Bus network design is an important problem in public transportation. A main step to this design is determining the number of required terminals and their locations. This is a special type of facility location problem, which is a time-consuming, large scale, combinatorial problem. In a previous attempt by the authors, this problem had been solved by GAMS, based on a branch and bound algorithm. ...

Water flooding is a well-known secondary mechanism for improving oil recovery. Conventional approach to evaluate the performance of a water flooding process (e.g. breakthrough and post breakthrough behavior) is to establish a reliable geological reservoir model, upscale it, and then perform flow simulations. To evaluate the uncertainty in the breakthrough time or post breakthrough behavior, thi...

Developers of novel scientific computing systems are often eager to make their algorithms and databases available for community use, but their own computational resources may be inadequate to fulfill external user demand – yet the system’s footprint is far too large for prospective user organizations to download and run locally. Some heavyweight systems have become part of designated “centers” ...

We propose an asynchronous iterative scheme that allows a set of interconnected nodes to distributively reach agreement within pre-specified bound in finite number steps. While this could be adopted wide variety applications, we discuss it the context task scheduling for data centers. In context, algorithm is guaranteed approximately converge optimal plan, given available resources, Furthermore...

Scheduling is a fundamental operating system function, since almost all computer resources are scheduled before use. The CPU is one of the primary computer resources. Central Processing Unit (CPU) scheduling plays an important role by switching the CPU among various processes. A processor is the important resource in computer; the operating system can make the computer more productive. The purp...
