Abstract: A variable structure model following controller (VSMFC) is designed for the tip position control of a single flexible link. The design is done for the system model in which only the first ...

Abstract: We show that a certain class of Hamiltonian systems with positive-definite potential admits, at each energy level, a continuum of solutions which satisfy the four Rosenberg conditions for normal modes.

Abstract: The statistical variance of total project cost is usually estimated by means of Monte Carlo simulation on the assumption that exact analytic approaches are too difficult. This paper tests that assumption and shows that, ...

Abstract: Time and cost are the most important factors to be considered in every construction project. In order to maximize the return, both the client and contractor would strive to optimize the project duration and cost concurrently. ...

Abstract: To improve the chance of success of a public-private partnership (PPP) scheme, it is essential to consider the feasibility of the scheme both from the economical and noneconomical perspectives according to the interests ...

Abstract: The selection of an appropriate project delivery system (PDS) is of paramount importance to an infrastructure project, as it could affect the success of the plan in terms of time, cost, and quality. Researchers have advocated ...

Abstract: The evaluation of consultant’s performance is crucial to the success of a consulting assignment especially when today’s construction projects are becoming more sophisticated, large-scale, and risky. However, since individual ...

Abstract: The mean thickness of a thin liquid film of deionized water with a free surface on a stationary and rotating horizontal disk has been measured with a nonobtrusive capacitance technique. The ...

Abstract: The current practice of contractor prequalification is characterized by the reliance on expert judgment and experiential knowledge. Previous studies have identified that the information concerning contractors' attributes ...

Abstract: In a real construction project, the duration and cost of each activity could change dynamically as a result of many uncertain variables, such as weather, resource availability, productivity, etc. Managers/planners must ...
