Requirements analysis includes a preliminary acquisition step where a global model for the specification of the system and its environment is elaborated. This model, called requirements model, involves concepts that are currently not supported by existing formal specification languages

Several recent studies have introduced lightweight versions of Java: reduced languages in which complex features like threads and reflection are dropped to enable rigorous arguments about key properties such as type safety. We carry this process a step further, omitting almost all features

This paper describes a simple heuristic approach to solving large-scale constraint satisfaction and scheduling problems. In this approach one starts with an inconsistent assignment for a set of variables and searches through the space of possible repairs. The search can be guided by a value

is that network is halted during the reconfiguring the virtual topologies. Therefore the delay of reconfiguration is important. Reconfiguration can be performed at one step or several step. Then, there is no research considering the sequence of reconfiguring. To maintain the survivability of networks

the modeling of various environments, relieving the modeler from the burden of low-level programming in a general-purpose language. Fleischer and Barr's work on the specification of environments supporting collisions and reaction-diffusion processes [20] is an inspiring step in this direction. Complexity

species. Ortholog clusters are seeded with a two-way best pairwise match, after which an algorithm for adding in-paralogs is applied. The method bypasses multiple alignments and phylogenetic trees, which can be slow and error-prone steps in classical ortholog detection. Still, it robustly detects complex

: specification, paired, and logic tests. The frame-work logs packet transmissions in the PCAP format to allow use of widely available packet analysis tools. Those tools help inspecting logical behaviour of student solutions, such as congestion control. We have designed five step-by-step assignments and evaluated

are preserved under partial isomorphism, by a simple induction. More precisely, one proves, for any assignment A and any partial isomorphism IÎI which is defined on the A-values for all variables x 1 , ..., x k , that M, A |= f iff N , IoA |= f . The crucial step in the induction is the quantifier case

and the Critical-Path-on-a-Processor (CPOP) algorithm. The HEFT algorithm selects the task with the highest upward rank value at each step and assigns the selected task to the processor, which minimizes its earliest finish time with an insertion-based approach. On the other hand, the CPOP algorithm uses

The purpose of this procedure is to ensure that SLAC’s environment, safety, and health (ESH) requirements are incorporated into the planning, procurement, and execution of green subcontracted work at SLAC. The SLAC work planning and control (WPC) program categorizes work activities as green, red, or yellow (see Chapter 2, “Work Planning and Control”). Green work is limited to those technical or administrative activities commonly performed by the public, posing well known hazards, with controls that may be implemented without permits or special ESH training, excluding training required to access an area (see Training: Minimum Training Requirements). This procedure applies to SLAC line management, points of contact (POC), procurement specialists, ESH coordinators, and subcontractor management and workers performing green work.
