Multimedia communication over wireless Ad-hoc networks has become the driving technology for many of the important applications, experiencing dramatic market growth and promising revolutionary experiences in personal communication, gaming, entertainment, military, security, environment monitoring, and more. The advances in wireless communications and growth of real-time applications have necess...

The job-shop scheduling problem is one of the most difficult problems in scheduling. This paper presents an improved constraint satisfaction adaptive neural network for job-shop scheduling problems. The neural network is constructed based on constraint conditions of a job-shop scheduling problem. Its structure and neuron connections can change adaptively according to the real-time constraint sa...

In this paper, we study efficient temporal planning based on a continuous and differentiable nonlinear programming transformation of the planning problem. Based on the observation that many large planning problems have constraint locality, we have previously proposed the constraint partitioning approach that utilizes the constraint structure by partitioning the constraints of a planning problem...

Scheduling is one of the main problems that need to be solved by high-level hardware and software compilers. Existing heuristics are often incapable of finding feasible solutions for practical examples, because the tight time and resource constraints make the feasible-solution subspace very small compared to the size of the full search space. For that reason, constraint-analysis techniques that...

recently, hardware sensors are widely used in monitoring and measurement of water quality parameters. constraint of the instrument to measure some water quality parameters such as the 5-day biochemical oxygen demand (bod5), which are time consuming, causes efforts are diverted to the use of software sensors for online prediction of bod5. the main goal of this research is developing an appropria...

Automatically extracted data is rarely “clean” with respect to pragmatic (real-world) constraints—which thus hinders applications that depend on quality data. We proffer a solution to detecting pragmatic constraint violations that works via a declarative and semantically enabled constraint-violation checker. In conjunction with an ensemble of automated information extractors, the implemented pr...

We present Data Auditor, a tool for exploring data quality and data semantics. Given a rule or an integrity constraint and a target relation, Data Auditor computes pattern tableaux, which concisely summarize subsets of the relation that (mostly) satisfy or (mostly) fail the constraint. This paper describes 1) the architecture and user interface of Data Auditor, 2) the supported constraints for ...
