A dimension reduction analysis is undertaken using ?-convergence techniques within a relaxation theory for 3D nonlinear elastic thin domains of the form where ! is a bounded domain of R 2 and f" is an "-dependent proole. An abstract representation of the eeective 2D energy is obtained, and speciic characterizations are found for nonhomogeneous plate models, periodic pro-les, and within the cont...

Small-sized hybrid wind-hydro-solar power generation systems may be designed to solve the power supply problem in some rural areas. Optimal design models are developed to design the hybrid generation systems including battery banks and to provide the optimum system configuration. It is ensured that the annualized cost of the systems is minimized while satisfying the required loss of power suppl...

We study interfirm competition on a product market where effort decisions are delegated to the firms’ workers. Intrafirm organization is captured by a principal-multiagent framework where firm owners implement alternative compensation schemes for the workers. We show that the value of delegation as well as the optimal design of the compensation scheme crucially depend on the intensity of compet...

The problem of designing controls for a linear dynamic system under input disturbance is considered. The input disturbance is bounded but the bound information is either deterministic or fuzzy. The control design is purely deterministic. However, the resulting system performance is interpreted differently, depending on the bound information. It may be deterministic or fuzzy (i.e. with a spectru...

his paper was prepared following the Royal Commission Research Unit and police representatives meeting held in Canberra in February 1989. The paper addresses behavioural design considerations for custodial environments in Australia, with particular focus on the situation of Aboriginal people in police custody and the prevention of deaths in custody. Specific design considerations and issues rai...

This Study describes a six degree -of-freedom hybrid simulation for the optimum design of a space vehicle re entry flight control system, utilizing the E A I HYDAC ® 2400 Combined Hybrid Computing System. The specific purpose of the simulation is the evaluation of a temperature-rate flight control system (TRFCS) which utilizes temperature sensors to provide shortperiod stabilization and long te...

This paper presents an adjoint method for the optimum shape design of unsteady flows. The goal is to develop a set of discrete unsteady adjoint equations and their corresponding boundary conditions for both the time accurate and non-linear frequency domain methods. First, this paper presents the complete formulation of the time dependent optimal design problem. Second, we present the time accur...

Considering the large amount of work that goes into the design of LNG processes there is surprisingly little attention to the subsequent operation. This probably comes from the misconception that optimal design and optimal operation is the same, but this is usually not true. In this paper we are studying optimal operation of a relatively simple LNG process, namely the PRICO process.
