Abstract: This technical correspondence presents a surprisingly simple analytical criterion for the stability of general second-order asymmetric linear systems. The criterion is based on the fact that if ...

Abstract: Guidelines for progress scheduling and control of department‐of‐transportation (DOT) construction projects are presented. The guidelines are based on best current practices and management techniques and are modified to ...

Abstract: An interactive system for analysis of construction operations is proposed. The analysis is carried out in the context of various work modules which address quantity development, resource definition, and production and cost ...

Abstract: The present work is concerned with the modeling of buoyancy-modified mixed convection flows, such flows being representative of low-flow-rate flows in the cores of Gas-cooled Reactors. Three ...

Abstract: Over the last several decades, several factors have contributed to a major transformation in heat pipe science and technology applications. The first major contribution was the development and ...

Abstract: In this paper, a new methodology for control of nonlinear unstable multivariable systems is developed. The method involves stabilization of the nonlinear plant followed by generation of sinusoidal input describing function ...

Abstract: The purpose of this paper is to present a new systematic procedure for synthesis of nonlinear controllers for single-input multiple-output systems. The procedure is based on several describing function models of the plant, ...

Abstract: The increasing competition in the construction industry today not only calls for lower bid prices but for accurate estimates as well. Therefore, a contractor must continuousiy strive to improve his or her estimating ...

Abstract: In many engineering applications, structured clay layers may be subjected to long-term loading and temperature variations. Review of the technical literature reveals that there are a number of constitutive models that deal ...
