This paper proposes and evaluates a model of supply chains as networks of auctions. In this model, companies are represented according to the first level of the Supply Chain Council’s SCOR model and the trading strategy of the agents is adapted from a model proposed by Steiglitz and colleagues. Specifically, the highest level of SCOR treats a company as comprising three functions, namely Source...

In a programming project, it is easy to lose track of which files need to be reprocessed or recompiled after a change is made in some part of the source. Make provides a simple mechanism for maintaining up-to-date versions of programs that result from many operations on a number of files. It is possible to tell Make the sequence of commands that create certain files, and the list of files that ...

Building the Nano composites for getting material with combinational properties and improving properties of currently used material has been taken significant attention. One of the ways of building Nano composites is using a method known as powder metallurgy. Because with this method not only wastes are decreased to minimum but we can also mix the materials with high melting point with the mate...

considering concepts such as emphasize on the role of the all stakeholders in urban regeneration, is one of the important and fundamental principles. this is important because in most cases, the private sector, government and municipal are considered more in process of intervention in distressed area and play a key role in this situation. but the role of people is often considered minor. empowe...

While it used to be satisfactory that sea r ch applications used to look up simple keywords in the past, nowadays a sea rch engine is increasingly expected to be able performing sema ntic sea rch as well. This leads to an intensified research on ontologies supporting these applications. Users might only have a vague idea of the exact keywords to the content they seek, especially when it comes t...

Some of the data available to today’s enterprise applications is inconsistent. This is an inevitable consequence of data being distributed and partially replicated in many locations. The usual approach to dealing with these imperfections is to attempt to drive them out at the application level, if not throughout the entire system. However, since at least some of the systems holding information ...

Irregular buildings make up a large portion of  urban infrastructure. Presence of irregularities can be due to architectural and  user changes in building stories. Main objective of this article is evaluate seismic performance of structures with vertical irregularities. Seismic responses are obtained by enveloping peak inelastic responses resulting from pushover analyses according to provided p...

It is generally said that code clone is one of the factors to make software maintenance difficult. A code clone is a code portion in source files that is identical or similar to another. Clones are introduced because of various reasons such as reusing code by ‘copy-and-paste’ and so on. Since developers usually modify the copied-and-pasted code portions, there are some gaps between the original...
