Within the past three years, several new AI textbooks have been published, all written by well-known researchers (Dean, Allen, and Aloiminos 1995; Russell and Norvig 1995; Shoham 1994; Ginsberg 1993). Thus, it is not surprising that the authors of each of these textbooks have sought a way to distinguish their own book from the rest. The hook for Stuart Russell and Peter Norvig's new textbook, A...

Problem Frames and i* are two broadly used approaches that require a good background from the requirements engineering. Both approaches have typical traits that fit in equivalent. On the other hand, there are features that do not fit. Thereby, there are some points which need improvements on both of them. This work analyzes the five basic problem frames, defined by Michael Jackson, in the i* co...

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

Trapezoidal prestressed unbonded retrofit (TPUR) systems have been recently developed and tested. The authors have already developed a comprehensive and accurate analytical solution for the TPUR system that takes many system parameters into account. The main aim of this paper is to develop a simplified analytical solution for predicting the behavior of metal beams that have been strengthened wi...

The purpose of this study is to examine the impact of the choice of cut-off points, sampling procedures, and the business cycle on the accuracy of bankruptcy prediction models. Misclassification can result in erroneous predictions leading to prohibitive costs to firms, investors and the economy. To test the impact of the choice of cut-off points and sampling procedures, three bankruptcy predict...

Consideration of comparative research as a "separate and different research process" is an issue that has not been addressed thoroughly, at least in Iran, and few of the research conducted under the title of "comparative" refer to studies conducted using different methods than the usual research methods. On the other hand, there has been a rise in the importance of interaction between different...

this paper presents the numerical analysis of seismic soil-pile-superstructure interaction in soft clay using free-field soil analysis and beam on winkler foundation approach. this model is developed to compute the nonlinear response of single piles under seismic loads, based on one-dimensional finite element formulation. the parameters of the proposed model are calibrated by fitting the experi...

previous studies have aimed at testing a hypothesis but the present study is data-first research in which researcher tries to form a theory from data rather than the use of data to test a hypothesis. this study aims at exploring teachers perceptions of the strengths and weaknesses of the current syllabus for college preparatory course. eight experienced teachers were selected to collect data du...

in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
