We present an overview over recent developments of traffic flow models for production networks. Particular emphasis is given to the implementation of service rules for complex systems, involving multiple product types and re entrant loops. A rather general scheduling concept is introduced and demonstrated on some numerical experiments.

| This paper describes the unrolling of loops with indeterminate loop counts in system level pipelines. Two methods are discussed in this paper. The rst method is the varied latency method, where the input is blocked until the pipeline is clear. This variation in the input arrival time gives rise to the name. In this method the output will be in the same order as the input. The second method, c...

Achieving a high fraction of peak performance on today’s computer systems is difficult for complex scientific applications. To do so, an application’s characteristics must be tailored to exploit the characteristics of its target architecture. Today, commercial compilers do not adequately tailor programs automatically; thus, application scientists must settle for lackluster performance or manual...

The assignments of the isoscalar scalar mesons f0(980), f0(1370), and f0(1500) in terms of their q̄q substructure is still a matter of heated dispute. Here we employ the weak and electromagnetic decays D+ s → f0π and f0 → γγ, respectively, to identify the f0(980) and f0(1500) as mostly s̄s, and the f0(1370) as dominantly n̄n, in agreement with previous work. The two-photon decays can be satisfacto...

An important problem facing parallelizing compilers for distributed memory mimd machines is that of distributing data across processors. This distribution aaects the amout of data movements among processors that is required to execute the computations of the input program. This work proposes a branch{and{bound based method to automatically compute a distribution for the arrays of the input prog...

The phase-locked loop (PLL)-based grid-following inverters have been widely used as the interface between renewable energy resources (e.g., wind and solar power) utility grid. In addition to basic PLL inner current control that are responsible for tracking phase angle of point common coupling (PCC) voltage regulating injection according estimated angle, respectively, these commonly also equippe...

Let An be the set of n X zero-one matrices satisfying matrix equation A2 = Jn; where Jn is all ones. In this article, it proved that number non-isomorphic left loops order k gives lower bound to size for k2. Mainly we have established any in corresponding loop has rank 2k - 2, k2, some positive integer k.
