The aim of this paper is the evaluation overall performance of buyer-supplier relationships.In some situations the cost of inputs in a buyer-supplier chain are available, on the other hand, achieving a low cost position is necessary for most businesses. And, in a buyer-supplier chain wants to know how assign inputs with the least cost. This paper introduces cost efficiency with same and dierent...

With ever increasing online repositories of video content, accurate and fast near-duplicate detection is important; it can help deter piracy and distribution of illegal content, while improving user experience when searching existing video collections by de-duplicating results and providing contextual data, such as links to similar videos or helping to extract meta data by clustering content. E...

computers. Scheduling here is in principle moderate co-scheduling, with which the order of priority of the specic parallel processes is controlled per xed time. In addition, as a method to change the order of priority of parallel processes simultaneously for conducting co-scheduling, the authors proposed and installed internal synchronization which takes advantage of the synchronous clock that ...

A solid travelling salesman problem (STSP) is a travelling salesman problem (TSP) where the salesman visits all the cities only once in his tour using dierent conveyances to travel from one city to another. Costs and environmental eect factors for travelling between the cities using dierent conveyances are dierent. Goal of the problem is to nd a complete tour with minimum cost that damages the ...

Data Envelopment Analysis (DEA) cannot provide adequate discrimination among efficient decision making units (DMUs). To discriminate these efficient DMUs is an interesting research subject. The purpose of this paper is to develop the mix integer linear model which was proposed by Foroughi (Foroughi A.A. A new mixed integer linear model for selecting the best decision making units in data envelo...

Envelopment Analysis (DEA) is a very eective method to evaluate the relative eciency of decision-making units (DMUs). DEA models divided all DMUs in two categories: ecient and inecientDMUs, and don't able to discriminant between ecient DMUs. On the other hand, the observedvalues of the input and output data in real-life problems are sometimes imprecise or vague, suchas interval data, ordinal da...

Several (and successfull) Information Extraction systems have recently replaced the core parsing components with shallow but more ecient recognizers. In this paper we argue that the absence of an underlying grammatical recog-nizer, given the complex nature of several (non-english) languages , is a strong limitation for text processing functionali-ties, like those an IE system needs. We propose ...

Synopsis The electron-proton colliding beam facility HERA consists of two independent accelerators designed to store 820 GeV protons and 27.5 GeV electrons. The two b e a m s circulate in opposite directions in an underground tunnel, 6.3 km in length. At t wo interaction points the beams are collided head on and some of the highest energy ep collisions ever attained are observed. The H1 detecto...
