Complex computing platforms such as High Performance Computers and Data Centers are critical systems from the energy sustainability viewpoint, due to their high computational power demanding thermal stability specifications. In this context, cooling is a crucial component operate efficiently. Adavanced solutions, based on liquid hybrid topologies available today, but they come with twofold chal...

Recently, because of the expansion of TCP/IP networks, the evaluation of IP networks is being considered as a major task for network operators and administrators. As a result, many IP evaluation tools have appeared, but almost all of them can only be applied to a limited purpose. The authors have already developed an IP evaluation tool, called KITS (KDD Internet Test System) [1] that can genera...

Distributed collaboration is becoming increasingly important also in software development. Combined with an increasing interest in experimental and agile approaches to software development, this poses challenges to tool support for software development. Specifically, tool support is needed for flexible, distributed collaboration. We introduce the Distributed Knight tool that provides flexible a...

this research, for the first time presents the flexible flow shop model of scheduling method for considering runway assignment and operations planning together. one of the advantages of the developed model is considering the procedures of air routes in terminal airspace and separation between consecutive aircraft which is very similar to the real world condition. there are different objective f...

One of the most important problems in production planning of flexible manufacturing system (FMS) is machine tool selection and operation allocation problem that directly influences the production costs and times .In this paper minimizing machining cost, set-up cost and material handling cost as a multi-objective problem in flexible manufacturing systems environment are considered. We present a ...

The Freeform Thick Layered Object Manufacturing (FF-TLOM) process is very suitable for the production of very large objects. The technology is based on flexible blade cutting of thick foam layers, which are stacked to create a physical model. Positioning the tool under accurate cutting constraints is a complex and difficult task, since the tool setting is controlled by 6 degrees of freedom. The...

On time replacement of a cutting tool with a new one is an important task in Flexible Manufacturing Systems (FMS). A fuzzy logic-based approach was used in the present study to predict and simulate the tool wear progress in turning operation. Cutting parameters and cutting forces were considered as the input and the wear rate was regarded as the output data in the fuzzy logic for construct...
