To model this, we introduce a binary variable xabr for each (unordered) pair of distinct trains a,b∈A(r), which is 1 if and only if a and b meet in r (i.e., the intersection of the time intervals spent by train
Since decoding complexity is proportional to the number of trellis states and branches, this tends to become excessively computationally expensive. 3.4.2 STBC Space-time block codes, as the name suggests, are block rather than trellis-based. In their best known form they avoid the complexity ...
A JAUS Subsystem can be large and complex, and complexity can increase over time as things are added. Things could be added without the oversight of a system engineer. Ethernet is susceptible to a DOS (Denial of Service) attack. Nodes are computers; they have operating systems which could be...
The provision to tripmakers of information, with varying degrees of resolution and accuracy, introduces considerable additional complexity in the system, as information could increase further the level of interaction, randomness and hence unpredictability of the system, or alternatively exert a regulation ...
The last decade of phylogenetics has seen the development of many methods that leverage constraints plus dynamic programming. The goal of this algorithmic technique is to produce a phylogeny that is optimal with respect to some objective function and tha
While using this pattern, you have to decide betweenunorderedWait(where it emits the result to the next operator as soon as the response is received, disregarding the order of the elements on the stream) andorderedWait(where it waits until all inflight I/O operations complete, then sends the...
DirectX 11引进了一种缓存类型,允许访问任一位置像素的值,该功能叫做UAV(unordered access view)。这个功能一开始只有像素着色器和compute shader可以用,到DirectX 11.1这里,所有的着色器都可以使用UAV功能。Opengl 4.3称这个功能为SSBO(shader storage buffer object)。两个名字都用他们自己的方式解释了这个功能。像素着...
A log is perhaps the simplest possible storage abstraction. It is an append-only, totally-ordered sequence of records ordered by time. It looks like this: Records are appended to the end of the log, and reads proceed left-to-right. Each entry is assigned a unique sequential log entry numb...
In the case of greatest interest, Arntzenius Continuum, every region has a unique complement so we may say a region has flat boundary if both it and its complement are convex. I shall restrict attention to that case. The unordered pair {u,v} consisting of two convex regions each the ...
In this paper we identify an extension of Petri nets with unordered data, for which this is not the case and continuous semantics leads to a substantial reduction in the complexity of the reachability problem. Unordered Data Petri Nets. The possibility of equipping tokens with some addi- tional...
