This paper presents a new client-driven pointer analysis algorithm that automatically adjusts its precision in response to the needs of client analyses. We evaluate our algorithm on 18 real C programs, using five significant error detection problems as clients. We compare the accuracy and performance of our algorithm against several commonly-used fixed-precision algorithms. We find that the cli...

this paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. a novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. parameters of the fuzzy estimator are adapted to minimize the estimat...

in present paper, a numerical analysis for a rectangular cavity filled with a anisotropic porous media has been studied. it is assumed that the horizontal walls are adiabatic and impermeable, while the side walls of the cavity are maintained at constant temperatures and concentrations. the buoyancy force that induced the fluid motion are assumed to be cooperative. in the two extreme cases of he...

driven precast reinforced concrete piles (dprcp) is extensively used as a foundation for bridges constructed over canals in egypt in order to avoid the diversion of water canals. the objectives of this research include identifying the main activities of dprcp execution in the bridge-construction industry in egypt and the risk factors affecting them. in addition, assessment of the effects of the...

Entrepreneurship is influenced by many factors and environments such as institutions. Institutions have an important role to play in the individual's tendency toward necessity and opportunity entrepreneurship. The purpose of this paper was to examine the impact of institutional quality (property rights) on opportunity and necessity entrepreneurship. The results, based on unbalanced panel data f...

Model transformations are pivotal artifacts in model-driven software projects. As with any software product, maintenance significantly contributes to the lifecycle costs. This is particularly true for model transformations. We present Transformation Analysis, a tool that supplements existing transformation editors under Eclipse with a graph view on the program’s data and control dependencies. T...

This paper deals with the Featured Driven Development (FDD), an agile software development method. According to the requirement analysis for the FDD method application, an information system has been created providing all team members with instruments to follow the method. This tool has been implemented as a multi-user web-based application enabling creation of feature lists, planning a project...

The manual measurement of functional size is generally very timeconsuming and has many precision errors. For this reason, it is necessary to automate the measurement process to obtain a solution that can be applied in a MDA industrial development. The OO-Method COSMIC Function Points (OOmCFP) is a measurement procedure that has been designed to measure the functional size of object-oriented app...

In this paper we overview the merits of a data dissemination mechanism that allows information to propagate from its producers to servers that are closer to its consumers. This dissemination reduces network traac and balances load amongst servers by exploiting geographic and temporal locality of reference properties exhibited in client access patterns. The level of dissemination depends on the ...

We explain two approaches to the design of system modeling frameworks and perform their comparative analysis. The analysis familiarizes the reader with strengths and weaknesses of the approaches, and thus helps to grasp the preferences for their practical applications. The first of the approaches is illustrated with the example of Model Driven Architecture (MDA), and the second – with the examp...
