Split 1

French heiress Franoise Dior had been linked to the NSM from 1962 and had become romantically involved with Jordan, before also taking up with Tyndall following the latter's release from prison. However following Jordan's own release the two were back on and they were married on 5 October 1963 in a ceremony that involved each allowing a drop of blood to fall onto a copy of Mein Kampf. Although the couple separated only three months later and were divorced, following a failed attempt at reconciliation, in 1967 the marriage drove a rift between Tyndall and Jordan which was complicated further by increasing ideological differences between the two men and a growing power base for the London-based Tyndall against the Coventry-based Jordan. Tyndall had increasingly echoed Bean's earlier criticisms of Jordan's open Nazism and at the April 1964 NSM conference Tyndall demanded that control of the movement be handed over to him. Tyndall was expelled on 11 May 1964 and the following day Tyndall claimed that he had expelled Jordan and assumed control of the movement. However ultimately Tyndall broke from the NSM, taking most of the HQ staff with him, and his followers would later emerge as the Greater Britain Movement. Before long the National Student Front, small group led by James McIntyre that worked for the NSM in universities, had also departed to offer support to Tyndall instead.

The 1980s: repression and split

During the early 1980s, the Syrian government clamped down on political activity and the Communist Party was subject to severe restrictions, despite its participation in the NPF. It was prevented from publishing its newspapers Nidhal ash-Sha'b ("the People's Struggle") and an-Nour ("the Light"), and its activities were closely monitored by the security services. It effectively operated underground throughout most of the 1980s, with membership lists a closely guarded secret. In 1986, the anti-communist crackdown ended and the ban on the communist party was lifted by Assad as a concession to the Soviets. In 1986, Bakdash and deputy secretary Yusuf Faisal differed over the policies of perestroika and glasnost adopted by Soviet Communist Party general secretary Mikhail Gorbachev. Faisal was supportive of Gorbachev's reforms, while Bakdash was opposed. This led to another split in the party, with many of the party's intellectuals leaving with Faisal while much of its Kurdish base remained supportive of Bakdash. Both factions retained the name "Syrian Communist Party" and continued to participate in the NPF.

Approaches for dealing with split-brain

Davidson et al., after surveying several approaches to handle the problem, classify them as either optimistic or pessimistic. The optimistic approaches simply let the partitioned nodes work as usual; this provides a greater level of availability, at the cost of sacrificing correctness. Once the problem has ended, automatic or manual reconciliation might be required in order to have the cluster in a consistent state. One current implementation for this approach is Hazelcast, which does automatic reconciliation of its key-value store. The pessimistic approaches sacrifice availability in exchange for consistency. Once a network partitioning has been detected, access to the sub-partitions is limited in order to guarantee consistency. A typical approach, as described by Coulouris et al., is to use a quorum-consensus approach. This allows the sub-partition with a majority of the votes to remain available, while the remaining sub-partitions should fall down to an auto-fencing mode. One current implementation for this approach is the one used by MongoDB replica sets. And another such implementation is Galera replication for MariaDB and MySQL. Modern commercial general-purpose HA clusters typically use a combination of heartbeat network connections between cluster hosts, and quorum witness storage. The challenge with two-node clusters is that adding a witness device adds cost and complexity (even if implemented in the cloud), but without it, if heartbeat fails, cluster members cannot determine which should be active. In such clusters (without quorum), if a member fails, even if the members normally assign primary and secondary statuses to the hosts, there is at least a 50% probability that a 2-node HA cluster will totally fail until human intervention is provided, to prevent multiple members becoming active independently and either directly conflicting or corrupting data.

Post split

Frankie StubbsAfter Leatherface split in 1993, Stubbs moved on to two new bands, Jesse and Pope. Jesse released three singles and one self-titled album between 1995 and 1998. Stubbs also performed solo and released one single in 1995 and a 10'' EP in 2001. He was referenced in Franz Nicolay's song 'Frankie Stubbs Tears'. 'Heart is Home' was among the first four VinylVideos ever produced. Other membersGraeme Philliskirk & Dickie Hammond went on to form Medictation with the remaining members consisting of members from Montreal, Quebec based band The Sainte Catherine's. Their debut LP Warm Places was released in 2016. Hammond died in October 2015.

Split Enz and Crowded House
Split Enz and Crowded HouseSplit EnzAt the departure of drummer Mal Green from Split Enz in 1981, their percussionist Noel Crombie took up the role of drummer. After the release of the Enz album Time and Tide in 1982, the band took a break to focus on other projects. According to the radio documentary Enzology, when they reformed in mid-1983, both Finn brothers returned somewhat distracted. Tim Finn had just released the very successful solo album Escapade, while younger brother Neil Finn had a child on the way. The reunion resulted in Conflicting Emotions (November 1983), an album which marked the beginning of the end for the band. Before the tour to support the album it was decided that Crombie would return to percussion (something he says he enjoyed more than drumming), and the band would find a new drummer. Hester was auditioned on the advice of Rob Hirst of Midnight Oil and got the job. In June 1984, founder Tim Finn left Split Enz, and they released See Ya 'Round in November which included "This is Massive" which was written by Hester. When Split Enz disbanded in December, Hester and Neil Finn decided to start a new group. Crowded HouseInitially, the new band formed by Hester and Neil Finn was named "The Mullanes" and then underwent a few name changes. They recruited Nick Seymour to play bass guitar and Craig Hooper on guitar, Hooper left as they secured a recording contract with Capitol Records in the US. However, Capitol disliked the name and the band changed to Crowded House to record their debut eponymous album, Crowded House in 1986. Other records by Crowded House with Hester are: Temple of Low Men (1988), Woodface (1991), Together Alone (1993), and the Best-of collection Recurring Dream (1996). By 1993 Hester was frustrated by the demands of his career and suffered a phobia about leaving to go on tour. On his return to Australia that year he started to see a psychiatrist. He remained with Crowded House until 1994, when the pressure of touring and the birth of his first daughter made him want to stay home, rather than remain on the road. Hester left mid-way through a 1994 tour of America, forcing the band to recruit British drummer Peter Jones for the rest of the tour. Hester performed with Crowded House at the band's farewell concert on the forecourt of the Sydney Opera House in 1996.— — — — — —Banana SplitBanana Split is a 2018 American comedy film directed by Benjamin Kasulke and starring Hannah Marks (who co-wrote the screenplay), Liana Liberato and Dylan Sprouse. It is Kasulke's feature-length directorial debut.— — — — — —Omaha hi-low split-8 or betterIn Omaha hi-low split-8 or better (simply Omaha/8), each player makes a separate five-card high hand and five-card ace-to-five low hand (eight-high or lower to qualify), and the pot is split between the high and low (which may be the same player). To qualify for low, a player must be able to play an 8-7-6-5-4 or lower (this is why it is called "eight or better"). A few casinos play with a 9-low qualifier instead, but this is rare. Each player can play any two of his four hole cards to make his high hand, and any two of his four hole cards to make his low hand. If there is no qualifying low hand, the high hand wins (scoops) the whole pot. This game is usually played in the fixed limit version, although pot limit Omaha/8 is becoming more popular. A few low-stakes online tournaments feature no limit Omaha/8. The brief explanation above belies the complexity of the game, so a number of examples will be useful here to clarify it. The table below shows a five-card board of community cards at the end of play, and then lists for each player the initial private four-card hand dealt to him or her, and the best five-card high hand and low hand each player can play on showdown: In the deal above, Chris wins the high-hand half of the pot with his J-high straight, and Bryan and Eve split the low half (getting a quarter of the pot each) with 7-5-3-2-A. Some specific things to notice about Omaha/8 hands are: In order for anyone to qualify low, there must be at least three cards of differing ranks 8 or below on the board. For example, a board of K-8-J-7-5 makes low possible (the best low hand would be A-2, followed by A-3, 2-3, etc.) A board of K-8-J-8-5, however, cannot make any qualifying low (the best low hand possible would be J-8-5-2-A, which does not qualify). Statistically, around 60% of the time a low hand is possible. Low hands often tie, and high straights occasionally tie as well, as do, even more rarely, full houses. In theory, it is possible to win as little as a 14th of a pot (though this is extraordinarily rare). Winning a quarter of the pot is quite common, and is called "getting quartered." One dangerous aspect of playing for the low pot is the concept of "counterfeiting". To illustrate, if a player has, for example, 2-3 and two other cards in his hand and the flop is A-6-7, that player has flopped the "nut low". However, if either a 2 or a 3 hit the board on the turn or the river, the hand is "counterfeited" and the nut low hand is lost (the player still has a much weaker low hand however, with 3-4, 3-5 and 4-5 making better lows). This is why there is significant extra value in possessing the "protected" nut low. To illustrate this, if the player has 2-3-4 in his hand his low is protected, i.e. if a 2 or 3 hits the board he still has the lowest possible hand. To lose the nut low in this case either a 2 and a 3, a 2 and a 4, or a 3 and a 4 would have to hit the board on the turn and the river (giving the nut low to a player holding 4-5, 3-5 and 2-5, respectively), an unlikely possibility. For similar reasons it is significantly better to possess the protected nut low draw over the low draw. For example, this could be having A-2-3 with a flop of 7-8-9; any low card below 7 on the turn or river gives the player the best low. When four or five low cards appear on the board, it can become very difficult to read the low hands properly. For example, with a board of 2 6 A 5 8, the hand 2 4 5 K is playing a 6-5-4-2-A (either his 2-4 with the board's A-5-6, or his 4-5 with the board's A-2-6--either way makes the same hand). In this situation he is often said to be playing his "live" 4, that is, his 4, plus some other low card that matches the board but still makes a low because the one on the board is not needed. A player with 3 5 10 J is playing a "live" 3, for a low of 6-5-3-2-A, which makes a better low. However, a player with 3 7 Q Q can only play 7-5-3-2-A low; even though he has a "live" 3, he must play two low cards from his hand, and so he must play his 7-3, and cannot make a 6-high low hand. Starting hands with three or four cards of one rank are very bad. In fact, the worst possible hand in the game is 2 2 2 2. Since the only possible combination of two cards from this hand is 2-2, it is impossible to make low. As no deuce remains to appear on the board, it will be impossible to make three deuces or deuces full, and anyone with any matching card to the board will make a higher pair. Likewise, starting with four cards of one suit makes it less likely that you will be able to make a flush. Starting with four different suits yields no chance for a flush, and starting with four disconnected cards reduces straight possibilities. Computer analysis of the best starting hands has proven that the best starting hand for Omaha is A-A-K-K (double suited). One favorite starting hand for Omaha is A-A-J-10 (double suited), because of its wider range for making the nut straight (J-7, Q-8, K-9, and A-10). For the Hi-Lo variation, the most valuable starting holding is A-A-2-3 (double suited). Hands to avoid tend to contain mainly middle-ranked cards, which are of little use for any low splits and which tend to generate lower pairs and sets, weaker flushes and lower straights and can be very expensive. Four of a kind is the worst possible starting hand in Omaha, in contrast to most other poker games, where it is exceptionally strong. Straights and flushes are ignored when judging low hands. Low hand ranks from best to worst: 5-4-3-2-A (the wheel), 6-4-3-2-A, 6-5-3-2-A, 6-5-4-2-A, ..., 8-7-6-5-4. Low hands can thus be read as numbers between 54,321 and 87,654 (with the exception of any number that has a pair, i.e. 54,322). The lowest number that any player can make, while ordered from high card to low, is the best possible low hand in play. For example: 2 3 5 6 7 wins over A 2 3 4 8
Split
Quilapayn's path has been marked by internal issues over the years, with some members leaving and others taking their place. In 1987 Willy Oddo, its most charismatic member, decided to leave France to be closer to Chile. He chose to live in Argentina. In October 1988, Pinochet was overthrown by a referendum. After 15 years of exile Quilapayun could return to Chile and performed tours in 1988, 1989, 1991 and 1992. In 1989 Eduardo Carrasco returned to Chile while most of the group continued to live in France and perform around the world. In November 1991 Willy Oddo was murdered by an offender in Santiago. After Rodolfo Parada registered the name "Quilapayn" without the authorization of the other members, other historic members refused to continue with Parada and Wang, resulting in the group splitting into two, both claiming the name and legacy of Quilapayn, and leading to subsequent litigation. The Chile-based historic faction is celebrating the group's 40 year anniversary performing concerts in Chile, Latin America and Europe, together with the "historic" version of Inti-Illimani, another important Chilean group. These joint concerts have been advertised and promoted as IntiQuila. The current "historic" lineup includes Eduardo Carrasco, Rubn Escudero, Ricardo Venegas, Guillermo Garca, Ismael Odd (son of Guillermo "Willy" Odd), Hugo Lagos, Hernn Gmez, Carlos Quezada and Sebastin Quezada (son of Carlos). On December 5, 2007, the Court of Appeal of Paris forbade Parada and Wang's group "from making use of the name QUILAPAYN, subject to a fine of 10 000 euros per infringement". This judgement was confirmed by the Highest Court of Appeal (Cour de Cassation de Paris) on June 11, 2009. In 2015 the band's career reached its fiftieth year and both factions celebrated this anniversary. Parada's group performed three big shows at the end August in Santiago, together with other well-known Chilean artists while the "historic" faction made a big concert in front of Palacio de la Moneda in Santiago and announced several other anniversary concerts in Chile, Colombia and Spain on its website. In November 2015, the Chilean trademark conflict ended, since the Instituto Nacional de Patentes Industriales (INAPI), after a thirteen years process gave the exclusive right for using the mark "Quilapayun" to the group headed by Carrasco.• Other Related Knowledge ofa split— — — — — —Non-split reductive groupsAs discussed above, the classification of split reductive groups is the same over any field. By contrast, the classification of arbitrary reductive groups can be hard, depending on the base field. Some examples among the classical groups are: Every nondegenerate quadratic form q over a field k determines a reductive group G = SO(q). Here G is simple if q has dimension n at least 3, since G k displaystyle G_overline k is isomorphic to SO(n) over an algebraic closure k displaystyle overline k . The k-rank of G is equal to the Witt index of q (the maximum dimension of an isotropic subspace over k). So the simple group G is split over k if and only if q has the maximum possible Witt index, n / 2 displaystyle lfloor n/2floor . Every central simple algebra A over k determines a reductive group G = SL(1,A), the kernel of the reduced norm on the group of units A* (as an algebraic group over k). The degree of A means the square root of the dimension of A as a k-vector space. Here G is simple if A has degree n at least 2, since G k displaystyle G_overline k is isomorphic to SL(n) over k displaystyle overline k . If A has index r (meaning that A is isomorphic to the matrix algebra Mn/r(D) for a division algebra D of degree r over k), then the k-rank of G is (n/r) 1. So the simple group G is split over k if and only if A is a matrix algebra over k.As a result, the problem of classifying reductive groups over k essentially includes the problem of classifying all quadratic forms over k or all central simple algebras over k. These problems are easy for k algebraically closed, and they are understood for some other fields such as number fields, but for arbitrary fields there are many open questions. A reductive group over a field k is called isotropic if it has k-rank greater than 0 (that is, if it contains a nontrivial split torus), and otherwise anisotropic. For a semisimple group G over a field k, the following conditions are equivalent: G is isotropic (that is, G contains a copy of the multiplicative group Gm over k); G contains a parabolic subgroup over k not equal to G; G contains a copy of the additive group Ga over k.For k perfect, it is also equivalent to say that G(k) contains a unipotent element other than 1. For a connected linear algebraic group G over a local field k of characteristic zero (such as the real numbers), the group G(k) is compact in the classical topology (based on the topology of k) if and only if G is reductive and anisotropic. Example: the orthogonal group SO(p,q) over R has real rank min(p,q), and so it is anisotropic if and only if p or q is zero. A reductive group G over a field k is called quasi-split if it contains a Borel subgroup over k. A split reductive group is quasi-split. If G is quasi-split over k, then any two Borel subgroups of G are conjugate by some element of G(k). Example: the orthogonal group SO(p,q) over R is split if and only if |pq| 1, and it is quasi-split if and only if |pq| 2.

I mean, what does changing a noun in a sentence depend on?They are all correct, but mean slightly different things."They want a banana" - this could mean they want one banana to share, or more likely that they want a banana each. The "each" is often understood, especially when the alternative meaning of 6 people sharing a banana seems unlikely. "They want banana" - this is using "banana" as an uncountable noun. This could be because "banana" is a flavour - "Which milkshake do they want?", "They want banana". Or perhaps because it is mashed banana, as a baby might eat "What do the twins want to eat?", "They want banana""They want bananas" - this is back to a countable noun, and in the plural. Now it is clear that more than one banana is involved
What's the Difference Between a Bi-level Home and a Split-level Home?
What's the difference between a bi-level home and a split-level home?Split-level is pretty much just two sections of a two-story home set side-by-side in construction but off-set half-way in height so you actually end up with four separate levels interior accessed by three seperate stairways. The front door can access a level foyer on any level. A Bi-level I think is just a 2-story colonial or a ranch walk-out. A split-foyer is what your front entry way is coming in from the front door— — — — — —Levels of ETCSETCS is specified at four numbered levels: Level 0: ETCS-compliant locomotives or rolling stock do not interact with lineside equipment, i.e. because missing ETCS compliance. Level NTC (former STM): ETCS-compliant driving cars are equipped with additional Specific Transmission Modules (STM) for interaction with legacy signalling systems. Inside the cabs are standardised ETCS driver interfaces. With Baseline 3 definitions it is called National Train Control. Level 1: ETCS is installed on lineside (possibly superimposed with legacy systems) and on board; spot transmission of data from track to train (and versa) via Eurobalises or Euroloops. Level 2: As level 1, but eurobalises are only used for the exact train position detection. The continuous data transmission via GSM-R with the Radio Block Center (RBC) give the required signalling Information to the drivers display. There is further lineside equipment needed, i.e. for train integrity detection. Level 3: As level 2, but train location and train integrity supervision no longer rely on trackside equipment such as track circuits or axle counters.Level 0Level 0 applies when an ETCS-fitted vehicle is used on a non-ETCS route. The trainborne equipment monitors the maximum speed of that type of train. The train driver observes the trackside signals. Since signals can have different meanings on different railways, this level places additional requirements on drivers' training. If the train has left a higher-level ETCS, it might be limited in speed globally by the last balises encountered. Level 1Level 1 is a cab signalling system that can be superimposed on the existing signalling system, leaving the fixed signalling system (national signalling and track-release system) in place. Eurobalise radio beacons pick up signal aspects from the trackside signals via signal adapters and telegram coders (Lineside Electronics Unit - LEU) and transmit them to the vehicle as a movement authority together with route data at fixed points. The on-board computer continuously monitors and calculates the maximum speed and the braking curve from these data. Because of the spot transmission of data, the train must travel over the Eurobalise beacon to obtain the next movement authority. In order for a stopped train to be able to move (when the train is not stopped exactly over a balise), there are optical signals that show permission to proceed. With the installation of additional Eurobalises ("infill balises") or a EuroLoop between the distant signal and main signal, the new proceed aspect is transmitted continuously. The EuroLoop is an extension of the Eurobalise over a particular distance that basically allows data to be transmitted continuously to the vehicle over cables emitting electromagnetic waves. A radio version of the EuroLoop is also possible. For example, in Norway and Sweden the meanings of single green and double green are contradictory. Drivers have to know the difference (already with traditional systems) to drive beyond the national borders safely. In Sweden, the ETCS Level 1 list of signal aspects are not fully included in the traditional list, so there is a special marking saying that such signals have slightly different meanings. Limited SupervisionWhereas ETCS L1 Full Supervision requires supervision to be provided at every signal, ETCS L1 Limited Supervision allows for only a part of the signals to be included, thus allowing to tailor the installation of equipment, only to points of the network where the increase in functionality justifies the costs. Formally, this is possible for all ETCS levels, but it is currently only applied with Level 1. As supervision is not provided at every signal, this implies that cab signalling is not available and the driver must still look out for trackside signals. For this reason, the level of safety is not as high, as not all signals are included and there is still reliance on the driver seeing and respecting the trackside signalling. Studies have shown that ETCS L1 LS has the same capacity as plain Level 1 FS for half the cost. Cost advantages come from reduced efforts necessary for calibrating, configurating and designing the track equipment and ETCS telegramms. Another advantage is, that Limited Supervision has little requirements for the underlying interlocking, hence it can be applied even on lines with mechanical interlockings as long as LEUs can read respective signal aspects. In contrast Level 2 requires to replace older interlockings with electronic or digital interlockings. That has led to railway operators pushing for the inclusion of Limited Supervision into the ETCS Baseline 3. Although interoperable according to TSI, implementations of Limited Supervision are much more diverse than other ECTS modes, e.g. functionality of L1LS in Germany is strongly based on PZB principles of operation and common signal distances. Limited Supervision mode was proposed by RFF/SNCF (France) based on a proposal by SBB (Switzerland). Several years later a steering group was announced in spring 2004. After the UIC workshop on 30 June 2004 it was agreed that UIC should produce a FRS document as the first step. The resulting proposal was distributed to the eight administrations that were identified: ÖBB (Austria), SNCB/NMBS (Belgium), BDK (Denmark), DB Netze (Germany), RFI (Italy), CFR (Romania), Network Rail (UK) and SBB (Switzerland). After 2004 German Deutsche Bahn took over the responsibility for the change request. In Switzerland the Federal Office of Transport (BAV) announced in August 2011 that beginning with 2018 the Eurobalise-based EuroZUB/EuroSignum signalling will be switched to Level 1 Limited Supervision. High-speed lines are already using ETCS Level 2. The north-south corridor should be switched to ETCS by 2015 according to international contracts regarding the TEN-T Corridor-A from Rotterdam to Genova (European backbone). But it is delayed and will be usable with December 2017 timetable change. Level 2Level 2 is a digital radio-based system. Movement authority and other signal aspects are displayed in the cab for the driver. Apart from a few indicator panels, it is therefore possible to dispense with trackside signalling. However, the train detection and the train integrity supervision still remain in place at the trackside. Train movements are monitored continually by the radio block centre using this trackside-derived information. The movement authority is transmitted to the vehicle continuously via GSM-R or GPRS together with speed information and route data. The Eurobalises are used at this level as passive positioning beacons or "electronic milestones". Between two positioning beacons, the train determines its position via sensors (axle transducers, accelerometer and radar). The positioning beacons are used in this case as reference points for correcting distance measurement errors. The on-board computer continuously monitors the transferred data and the maximum permissible speed. Level 3With Level 3, ETCS goes beyond pure train protection functionality with the implementation of full radio-based train spacing. Fixed train detection devices (GFM) are no longer required. As with Level 2, trains find their position themselves by means of positioning beacons and via sensors (axle transducers, accelerometer and radar) and must also be capable of determining train integrity on board to the very highest degree of reliability. By transmitting the positioning signal to the radio block centre, it is always possible to determine that point on the route the train has safely cleared. The following train can already be granted another movement authority up to this point. The route is thus no longer cleared in fixed track sections. In this respect, Level 3 departs from classic operation with fixed intervals: given sufficiently short positioning intervals, continuous line-clear authorisation is achieved and train headways come close to the principle of operation with absolute braking distance spacing ("moving block"). Level 3 uses radio to pass movement authorities to the train. Level 3 uses train reported position and integrity to determine if it is safe to issue the movement authority. Level 3 is currently under development. Solutions for reliable train integrity supervision are highly complex and are hardly suitable for transfer to older models of freight rolling stock. The Confirmed Safe Rear End (CSRE) is the point in rear of the train at the furthest extent of the safety margin. If the Safety margin is zero, the CSRE aligns with the Confirmed Rear End. Some kind of end-of-train device is needed or special lines for rolling stock with included integrity checks like commuter multiple units or high speed passenger trains. A ghost train is a vehicle in the Level 3 Area that are not known to the Level 3 Track-side. ERTMS RegionalA variant of Level 3 is ERTMS Regional, which has the option to be used with virtual fixed blocks or with true moving block signalling. It was early defined and implemented in a cost sensitive environment in Sweden. In 2016 with SRS 3.5 it was adopted by core standards and is now officially part of Baseline 3 Level 3. It is possible to use train integrity supervision, or by accepting limited speed and traffic volume to lessen the effect and probability of colliding with detached rail vehicles. ERTMS Regional has lower commissioning and maintenance costs, since trackside train detection devices are not routinely used, and is suitable for lines with low traffic volume. These low-density lines usually have no automatic train protection system today, and thus will benefit from the added safety. GNSSInstead of using fixed balises to detect train location there may be "virtual balises" based on satellite navigation and GNSS augmentation. Several studies about the usage of GNSS in railway signalling solutions have been researched by the UIC (GADEROS/GEORAIL) and ESA (RUNE/INTEGRAIL). Experiences in the LOCOPROL project show that real balises are still required in railway stations, junctions, and other areas where greater positional accuracy is required. The successful usage of satellite navigation in the GLONASS-based Russian ABTC-M block control has triggered the creation of the ITARUS-ATC system that integrates Level 2 RBC elements - the manufacturers Ansaldo STS and VNIIAS aim for certification of the ETCS compatibility of this system. The first real implementation of the virtual balise concept has been done during the ESA project 3InSat on 50 km of track of the Cagliari-Golfo Aranci Marittima railway on Sardinia in which a SIL-4 train localisation at signalling system level has been developed using differential GPS. There is a pilot project "ERSAT EAV" running since 2015 with the objective to verify the suitability of EGNSS as the enabler of cost-efficient and economically sustainable ERTMS signalling solutions for safety railway applications. Ansaldo STS has come to lead the UNISIG working group on GNSS integration into ERTMS within Next Generation Train Control (NGTC) WP7, whose main scope is to specify ETCS virtual balise functionality, taking into account the interoperability requirement. Following the NGTC specifications the future interoperable GNSS positioning systems, supplied by different manufacturers, will reach the defined positioning performance in the locations of the virtual balises.
Problems of Phased Array Ground Penetrating Radar Detection System
Although GPR has been widely used in hydrology, engineering, environment and other fields, many basic theoretical and technical problems have not been fundamentally solved, so the real advantages of GPR have not been brought into full play.The main problems existing in GPR technology include:1) The detection depth is shallow, and the contradiction between detection depth and resolution cannot be overcome. Increasing detection depth means sacrificing detection resolution;2) Multiple spread and other clutter jamming are serious, and there has been no good elimination method, which exists in radars at home and abroad;3) The influence of medium unevenness is great and can not be eliminated, resulting in difficulty in obtaining necessary velocity data;4) The data collection method of single sending and single receiving can provide limited information for post-processing and interpretation.The above problems are fatal defects for GPR. Although many geophysicists, electromagnetic experts and geophysical workers have done a lot of research and improvement on radar antenna design, signal processing and underground target imaging, these works are only partial modifications to the existing GPR system. In order to develop GPR technology, we must update our ideas and solve the problems from the fundamental principle.In view of this situation, experts proposed to develop a new GPR system - phased array GPR detection system in 1999.The basic research idea is to replace the current monopole radar antenna with the phased array radar antenna by using the relatively mature military phased array radar technology. Its purpose is to gather the electromagnetic wave into a narrow beam to transmit underground (or detection object) through the phased array technology, and receive the radar echo signal reflected by the target by using the multi-channel acquisition technology, The advanced data processing is carried out, and finally the three-dimensional image of the internal structure of the detection object is given.Development prospect of ground penetrating radar technologyIt is worth noting that at present, similar products have appeared in the market, such as RIS antenna array series of a company, but these products simply combine multiple monopole antennas into array antennas, which is essentially different from the idea of phased array ground penetrating radar.Because the phased array radar converges the electromagnetic wave into a narrow beam by controlling the phase delay of each channel, the energy is concentrated and the wave front diffusion is small. Therefore, the detection depth of the phased array radar is much larger under the condition of the same frequency and transmission power; On the contrary, under the same detection depth, phased array radar can improve the transmission power, so its resolution is much higher than the existing radar. In addition, since the spherical wave transmission is changed to beam transmission, the influence of medium heterogeneity is much smaller.Secondly, the phased array radar works in a continuous scanning mode and can scan in multiple directions. Therefore, the amount of information is much larger than that of the existing ground penetrating radar. For some special detection work, such as the quality detection of embankment cut-off wall, its role is unmatched by the existing ground penetrating radar (monopole antenna radar can not detect the joints, forks and other defects of embankment cut-off wall at all).Because phased array radar is a multi-channel received signal, multi-channel superposition can be carried out, just like the multiple coverage technology of reflection seismic exploration. Therefore, multiple interference can be greatly eliminated, which is difficult for existing radars. The antenna of high frequency (600mhz-1ghz) phased array ground penetrating radar can be made smaller, and its advantages are unmatched by the existing ground penetrating radar in shallow detection.At present, the system prototype has been completed. The carrier free pulse working system with center frequency of 900MHz is adopted, and the transmitting and receiving antennas are separated. 16 (4 × 4) Transmit channel forming, beam aggregation and scanning 16 (4) × 4) The channel receives the echo, and the optional scanning angles are - 36 °, - 24 °, - 12 °, 0 °, 12 °, 24 ° and 36 °.The software part of the system has rich data processing functions. The main conventional processing includes filtering, gain adjustment, static and dynamic correction, deconvolution, complex signal analysis, time-frequency analysis, etc., and multi-channel data processing, such as velocity analysis, superposition technology, coherence analysis technology, array signal processing, etc. And weak signal extraction, target automatic recognition and inversion interpretation under various clutter interference. A large number of field experiments on concrete detection in Yichang Three Gorges dam are carried out. The experimental results show that the spotlight scanning function of phased array radar has been realized, the penetration depth is greater than 1.5m and the resolution is higher than that of ordinary radar.Editing: hfy
Suggestions for Journaling, Bullet Notes, Activity, Wiki Like Application
So I am thinking of a possible answer to my own question:Build my own journal note entry app linked to a wiki.Zim Wiki uses a file based system for wiki. Maybe I could write app to export/sync entries in its files. Or WikkaWikki uses a MySQL (which is probably what I would use for journal entries anyway) so perhaps use same DB for Wiki and journal, with Journal app "doing right thing" to enter/sync Entries in wiki.Does this seem like a good approach?Or maybe I can customize a wiki with existing plugins - "All" I really need is good journaling / date feature, time tracking, checklist, and tags. Perhaps there already are plugins for this?Please comment if you have feedback on this idea.1. Circular tag wiki excerptsTag excerpts should at least try and give a concise definition as to the subject, and provided any usage guidance if necessary.Therefore, you need to make sure to address a set of key points:In general, excerpts should provide at least some guidance, even if it may appear to be ridiculously basic. Therefore, interpretation of the rejection reason is critical:That's like saying, [abs]: For questions about [abs] filaments. That should probably be rejected. This is better: [abs]: For questions about [abs] filaments - filaments that are used with blah blah printers, and are not toxic for use.Or even better: [abs]: For questions about [abs] filaments - filaments that are used with blah blah printers, and are not toxic for use. Not to be confused with [pla] filaments. Do not use this tag if your question does not concern this filament specifically. Obviously, I have no idea if abs is even a thing. Anyways, I hope this helps :)2. Why is this answer a community wiki?Apparently the answer under scrutiny was made CW because it drew on an answer from another Stack site, and the answerer wanted to share it without being associated with it for good or for ill.But community wiki is not a tool for reputation denial (or for dodging the repercussions of questionable-quality answers) and practically speaking I see no difference between quoting a different Stack and quoting a blog or a book. We would never expect someone to eschew rep for quoting a blog or a book. The answerer went to the trouble of tracking down the information and sharing it; why should not rep gains should reflect that?The moderation team is under no obligation to revert the CW in this case, nor are they obligated to leave it be, but I would lean toward reverting it myself, for reasons which follow.We've talked about posting answers from other sites, and it's pretty clear this is not cheese.Community wiki used to be massively overused. Changes to the editing system rendered its original purpose largely moot, and there's now a lot of confusion about CW's role in the Stack mechanics. These days there are three basic reasons to use CW:I do not see this particular answer needing CW to make it "easier to edit and maintain by a wider group of users," so I do not see any reason for it to be a community wiki. Community wiki is a tool with a specific set of uses, and CW rollbacks are left to mod discretion. One of the responsibilities of our moderators is to help the community use the right tools for the job at hand.As for the answer itself--it's not very good by lit.se standards, because it was written for a different site with different priorities. And the question itself is under a tag whose implementation is still being debated, so quality there is... in flux, I suppose we could say. We need to bring in our own expertise and tailor the answer to meet the expectations of our own Stack.3. Need to Change Edit Approval Limits for Tag Wiki EditorsI just upped it from 3 to 5. Hopefully this alleviates the issue a bit. If we still notice a pattern of users being blocked we can look at adjusting further4. Difference between Wiki Library and Document LibraryYes there is difference, Below might be helpful to understand.Document library can contains documents, it can be any document like office documetnts doc,xls,ppt, js, css, jpg, png etc...any file extension you can think of. Main purpose of document library is to store documents. wiki library is a kind of document library which contains wiki pages, Wiki pages are html pages with rich text editing capabilities so that users can create pages using Rich Text Editor without knowing html in detail. So when wiki library template is selected it comes with some default columns created based on content type, this columns are useful to create wiki page. Making changes and edits in a wiki page is incredibly easy. Just click on the edit button (at the top of the page) and immediately the page appears as an editor's version of the page. You can then make edits straight away and simply hit save. The page will instantly be up and running with your changes in place.
How Many NCAA Football Bowls Are There?
About 8 I think1. where can i get ncaa football 10 rosters with names?For the last two years I got mine from "Pastapadre". From what i can tell they are really pretty accurate. Give it a shot2. where can I watch NCAA football games for free?...?Try channelsurfing.net. They pick up a lot of justin.tv stuff, and they have loads of ncaa football games, free, no spam, etc. I watch all the time with no problems3. Can you download a team on NCAA Football 10's Team Builder using a flash drive?Why would you want to do that? Build your own team. Do not take the wussy way out.4. NCAA Football 13 Heisman Challenge 3 Player Pack?The exclusive Heisman Challenge 3-Player Pack including Mark Ingram, Tim Tebow and Matt Leinart. See if you can match the career accomplishments of these former Heisman trophy winners in the all new Heisman Challenge Mode. Its come with your ordered game copy5. What ncaa football team is your favorite one?Oklahoma SOONERS!6. I want to do a dynasty in NCAA Football 14 what team should I use (I want it to be a challenge like a weaker)?Vanderbilt, they are in a great conference and are already headed in the right direction as far as getting better and it will be a challenge because you will be in the SEC7. does ncaa football deserve a playoffs instead of bowl games being based off of BCS rankings?Whether or not the NCAA deserves a playoff does not matter. They do not want one so they do not have one. Frankly, the national championship playoff debate is a joke. This is something created by sportswriters and tolkshow hosts for the sole benefit of sportswriters and talkshow hosts. The NCAA does not recognize a national champion of the FBS so any discussion about who should or should not be the champion is pointless bloviating. Win your conference. Beat your rivals. Go to a bowl game. Those are the only things that matter in college football.8. What was determining the NCAA football title like in pre-BCS years?Hawaii, is not a very reliable team, yet might desire to win the Sugar Bowl in simple terms as surely as Georgia as a results of fact their offense constantly performs like its at the back of and it wears down the protection whilst they might desire to conceal the whole field. The unfold offense is the excellent offense in college soccer. It supplies much less gifted communities liek Hawaii and Illinois a gamble to beat far extra gifted communities. that's alsovery risky, that's why some exceptionally ranked communities dont run it. Hawaii surely did no longer deserve a identify shot in simple terms as a results of fact Boise State gained The Fiesta Bowl. Boise beat a BCS convention team who complete 10-4(Oregon State who beat USC and Hawaii in Hawaii) Hawaii has no high quality wins and does not deserve a NT shot. ending undefeated might desire to get you a BCS sport nevertheless9. NCAA Football 2009-What Defense to run online?Usually the defense package that comes with the team you are using as the best combo of players are on the field10. Which Championship/Playoff Picture needs more work....the NFL or NCAA Football?everybody keeps blaming the computers, but the computers are pretty much the only good part about the BCS, it only counts as 1/3 anyways. another 1/3 is coaches, former players, former athletic directors and people like that, the other third is the media. a lot of voters admitted to not even watching a utah game until they played alabama, how messed up is that. so lets put the blame where it really belongs, the stupid voters, who do not educate themselves about what or who they vote for11. could an NCAA football team beat a weak pro team?No-NCAA teams always have weak links and for the most part are BOYS.NFL teams have chosen the best of the best,and are MEN12. What teams rush the ball the most in ncaa football?its either navy or army one of them thats pretty much all they do13. What D1-AA teams are in NCAA Football 08?Usually they are. Just check out some of the SEC teams schedules. You find a lot of them there. Looks like the truth hurts down there!

Your original cocktail was a solution of lots of non-volatile components (sugar, Splenda, citric acid from the lemon juice, and many many other things...) in some rather more volatile solvents (ethanol and water). Only a limited amount of any of the non-volatile compounds can dissolve in a given volume of solution. So as the volatile compounds evaporated, your solution gradually became saturated, then a little super-saturated, and then finally the non-volatile components started to crystallise out in the patterns you show.In general slow evaporation of a solvent is quite a common method of crystal growth, e. g. , for X-ray diffraction studies.— — — — — —OK, its the last day of mankind, and you can have one mixed drink/cocktail, what would it be?Tequilini Ingredients: 2 1/2 oz Casa Noble Tequila Crystal Few Drops of Dry Vermouth 1/2 oz Fresh Lime Juice Mixing instructions: Shake ingredients in mixing glass with ice, then strain into a cocktail glass.— — — — — —how do you make a frozen bikini cocktail?well firstly buy a bikini freeze it and then add it to a cocktail glass and add required bverages which i dont know what they are— — — — — —Drink Recipe?'?????????There are a lot of them, any of these sound right?

Automotive Backup Camera Systems, Backup Hub
rsync can be somewhat painful if you have a very large number of files - especially if your rsync version is lower than 3. On the other hand: if you use tar, you would generate a very big resulting tar-file (unless the data may be compressed a lot). Personally, I would look at rdiff-backup, but make sure that you test your restore situation: rdiff-backup can be very memory demanding when restoring.1. Backup files being created in KubuntuIt seems you forgot to ask the question :) I will assume the question is "how do I disable creation of backup files in Kate"The answer is: go to Settings - Configure Kate - Editor Component - Open/Save - Advanced and untick "Backup on Save" for Local Files and Remote Files. Then click OK2. Ubuntu 10.10 full backupThe problem is not just re-installing Ubuntu it is also all the peripheral programs that I have on my HD. Some take much effort and time to reinstall, setting up configuration files etc. WE really do need a one-button HD back up.. I would like to do this onto a USB HD ..can it be so hard, Apple have it!!..? ron..Themotorman3. GPO backup failsYou may have to troubleshoot a little further. Are you able to backup other GPOs? Did you try using an alternative admin account? Can you create a test one and back that up? If you can, then I would check permission on the previous GPO where you are receiving the error. There is a powershell command you can use:Backup-Gpo -Name MYGPO -Path C:GpoBackup -Comment "Backup-08-21-14".4. rsync --backup-dir not getting changed data - instead it is going to the original backup locationI suppose the options -b --backup-dir do not act as you hope. You can try to use a different option --link-dest instead. Your command line should be similar to the following What is the meaning? You are telling to rsync to compare the files in /scripts/source/ (the new ones) with the ones in /scripts/diff/ (that is empty) and in the additional directory /scripts/full/ (That is the one of your backup).Notes:5. Backup internals - What happens when a backup job is running - in terms of locking and performance overhead in SQL Server?Basically, SQL Server does a dirty copy of all pages on disk. Those pages are likely inconsistent if there is concurrent activity or if there previously way non-checkpointed activity.Then, SQL Server also copies the necessary part of the transaction log that is needed to bring the out of date pages to the latest version and make everything consistent on restore. I can not speak to the multi-threadedness of the backup operation. I expect it to be parallelized. How else could you back up a 10TB database on a 10GB/sec IO subsystem?6. amt .22 backup jam problem?Its the nature of the gun. Try this, and it will sound weird. Clean the gun, and then try to feel the feed ramp for burrs. If you can feel some, use a dremmel tool, and a mild abrasive for polishing metal, and a cloth wheel, to polish it smooth. To feel the burrs best, use your tongue. It is more sensitive than your fingers. This should resolve the problem, or at least be all that you can do. If it does not resolve the problem, you can put the gun on your desk as a real cool paper weight, as that it is truly only reliable for that. Bringing it to a gunsmith is an option, but they often will charge more to work the ramp, throat, and barrel than the gun is worth. Go buy a small Ruger SP101 in .357 if you want a back up. Good Luck.7. How to backup / partition before rooting?Those on Android 6 can try the instructions that I posted here, starting at step 5. I think this will work without root, but I have not tried. You will need 6 if you are running stock because some of these commands require tools only included in Toybox. See also Ryan Conrad's great answer, based on this xda-developers guide, also linked by Firelord above8. Ramifications of Deleting Transaction Log BackupSo order of operation:If this is correct then you will be fine. As long as the LSN or chain of (backup) events since the last full backup is not broken you should have no issues with recovery
Blockchain Technology Explained: Powering Bitcoin
Blockchain Technology Explained: Powering BitcoinMicrosoft recently became the latest big name to officially associate with Bitcoin, the decentralized virtual currency. However, the Redmond company did not go all out, and will only support bitcoin payments on certain content platforms, making up a tiny fraction of its business.What is The Big Deal With Bitcoin?Like most good stories, the bitcoin saga begins with a creation myth. The open-source cryptocurrency protocol was published in 2009 by Satoshi Nakamoto, an anonymous developer (or group of bitcoin developers) hiding behind this alias. The true identity of Satoshi Nakamoto has not been revealed yet, although the concept traces its roots back to the cypher-punk movement; and there's no shortage of speculative theories across the web regarding Satoshi's identity.Bitcoin spent the next few years languishing, viewed as nothing more than another internet curiosity reserved for geeks and crypto-enthusiasts. Bitcoin eventually gained traction within several crowds. The different groups had little to nothing in common — ranging from the gathering fans, to black hat hackers, anarchists, libertarians, and darknet drug dealers; and eventually became accepted by legitimate entrepreneurs and major brands like Dell, Microsoft, and Newegg.While it is usually described as a "cryptocurrency," "digital currency," or "virtual currency" with no intrinsic value, Bitcoin is a little more than that. Bitcoin is a technology, and therein lies its potential value.This is why we wo not waste much time on the basics — the bitcoin protocol, proof-of-work, the economics of bitcoin "mining," or the way the bitcoin network functions. Plenty of resources are available online, and implementing support for bitcoin payments is easily within the realm of the smallest app developer, let alone heavyweights like Microsoft. Looking Beyond The Hype — Into The BlockchainSo what is blockchain? Bitcoin blockchain is the technology backbone of the network and provides a tamper-proof data structure, providing a shared public ledger open to all. The mathematics involved are impressive, and the use of specialized hardware to construct this vast chain of cryptographic data renders it practically impossible to replicate.All confirmed transactions are embedded in the bitcoin blockchain. Use of SHA-256 cryptography ensures the integrity of the blockchain applications — all transactions must be signed using a private key or seed, which prevents third parties from tampering with it. Transactions are confirmed by the network within 10 minutes or so and this process is handled by bitcoin miners. Mining is used to confirm transactions through a shared consensus system, and usually requires several independent confirmations for the transaction to go through. This process guarantees random distribution and makes tampering very difficult.While it is theoretically possible to compromise or hijack the network through a so-called 51% attack the sheer size of the network and resources needed to pull off such an attack make it practically infeasible. Unlike many bitcoin-based businesses, the blockchain network has proven very resilient. This is the result of a number of factors, mainly including a large investment in the bitcoin mining industry.Blockchain technology works, plainly and simply, even in its bitcoin incarnation. A cryptographic blockchain could be used to digitally sign sensitive information, and decentralize trust; along with being used to develop smart contracts and escrow services, tokenization, authentication, and much more. Blockchain technology has countless potential applications, but that's the problem — the potential has yet to be realized. Accepting bitcoin payments for Xbox in-game content or a notebook battery does not even come close.So what about that potential? Is anyone taking blockchain technology seriously?Originally published at DreamiFly.— — — — — —Please explain me what is blockchain and how is it useful?Blockchain Technology is an upcoming term mostly heard in relation to the cryptocurrencies. This record-keeping tech is very important for bitcoins. In addition to this one can also see the use of Blockchain technology in sectors like banking and investing. It also enables a community of users to control the revision and any necessary updates for the record of information. On this level Blockchain technology seems quite similar to Wikipedia. In Wikipedia, a number of users contribute to a single content. But the main difference between the 2 is in their digital backbone. Wikipedia has a highly protected centralized database. The total control over this centralized database lies with the owner. The owner manages all updates, accesses and also protecting against any cyber threats. On the other hand, for the distributed database of the Blockchain technology, every node in the network has to come to the same conclusion while each updating the record independently. Thereafter only the most popular record is held at the official record instead of the existing master copy.
