People traditionally have considered the number of counters in the critical path as the met ric for the performance of a multiplier This report presents the view that tree topologies which have the least number of levels do not always give the fastest possible multiplier when constrained to be part of a microprocessor It proposes two new topologies hybrid struc ture and higher order arrays whic...

the collapse of a compression member gives rise to decrease of the load carrying capacity of the member. to perform a nonlinear analysis, in addition to the precritical behavior, the post-critical behavior of the compression member also must be determined. in this study, because of certain advantages of the finite element method, this method has been selected to evaluate the axial load-axial di...

Modern processors come close to executing as fast as true dependencies allow. The particular dependencies that constrain execution speed constitute the critical path of execution. To optimize the performance of the processor, we either have to reduce the critical path or execute it more efficiently. In both cases, it can be done more effectively if we know the actual path. This paper describes ...

chickpea (cicer arietinum l.) is one of the most important crops worldwide that is a subject of many plant breeding programs in many countries. in addition, climates are changing all over the world and drought becomes one of the most serious problems versus yield of crops. in order to screen drought tolerant genotype in chickpea, twenty genotypes were tested under rainfed and irrigated conditio...

Introduction: Unit risk management is a critical component of gas refining management, as risks that are not well-managed may lead to trip production failures. The present study aimed to provide a structural model for investigating the role and effect of different variables on stopping the gas production process in the gas refinery. Material and Methods: This study was a retrospective cross-se...

Project planning is part of project management, which is relates to the use of schedules such as Gantt charts to plan and subsequently report progress within the project environment. Initially, the project scope is defined and the appropriate methods for completing the project are determined. In this paper a new approach for the critical path analyzing a project network with random fuzzy activi...

in order to study the correlation between morphophenological and quantitative traits with yield and to determine the most important traits for yield, 600 ecotypes of mung bean were evaluated in normal and limited irrigation conditions through augmented design. computation of correlation coefficients showed that in two conditions, number of pods per plant, harvest index and biological yield had ...

To my family: for their continuous love and support. ii ACKNOWLEDGEMENTS This dissertation marks the end of a chapter of my life. My journey through school has been aided by many people over the years and I'm thankful for all their help and support. First, I must thank my family. They have always encouraged me to learn and have been supportive in every way they could be. My mother, Raghda Saidi...
