Web service composition (WSC) offers a range of solutions for rapid creation of complex applications by facilitating the composition of already existing concrete web services. One critical challenge in WSC is the dynamic selection of concrete services to be bound to the abstract composite service. In our research, we identify and elaborate on the challenges involved on developing a market-based...

We present a new localization algorithm called Sensor Resetting Localization which is an extension of Monte Carlo Localization. The algorithm adds sensor based resampling to Monte Carlo Localization when the robot is lost. The new algorithm is robust to modelling errors including unmodelled movements and systematic errors. The algorithm can be used in real time on systems with limited computati...

The League of Arab States (also known as the Arab League) is well past its sixth decade of establishment. However, it has a long way to go to achieve the objectives enumerated in its charter. In a sense, there is much stronger propensity towards disintegration than integration in the League. This article seeks to study the reasons that account for the failure of such integration in the Arab Lea...

The class of modern datacenters recently coined as “warehouse scale computers” (WSCs) has traditionally been embraced as homogeneous computing platforms. However, due to frequent machine replacements and upgrades, modern WSCs are in fact composed of diverse commodity microarchitectures and machine configurations. Yet, current WSCs are designed with an assumption of homogeneity, leaving a potent...

the aim of this paper was to identify the strengths, weaknesses, opportunities and threats of talent identification in championship sport of i.r. iran and to examine its bottlenecks and challenges. for data collection, the documents and related literature were reviewed, council meetings were held and a researcher-made questionnaire and swot analysis were used. 256 subjects including 13 managers...

Because of reducing the number of spectators of football premier league, this study is seeking for identifying factors put the most impact on this decline. The statistical population consisted of all spectators in Iran football premier league in 2015-16, out of which 395 spectators were randomly selected as the research samples. The data were collected via a researcher-made questionnaire. The f...

Plenty of work based on the Rapidly-exploring Random Trees (RRT) algorithm for path planning in real time has been developed recently. This is the most used algorithm by the top research teams in the Small Size League of RoboCup. Nevertheless, we have concluded that other simpler alternatives show better results under these highly dynamic environments. In this work, we propose a new path planni...

Using data from professional baseball, basketball, and hockey, we estimate the parameters of a sequential game model of best-of-n championship series controlling for measured and unmeasured differences in team strength and bootstrapping the maximum-likelihood estimates to improve their small sample properties. We find negligible strategic effects in all three sports: teams play as well as possi...
