Redundancy optimization problem with cost constraints is a typical problem in reliability engineering. This study investigates standby redundancy optimization problem with uncertain lifetimes and uncertain costs. Three models for optimizing different performances of a standby system are formulated. In these models, maximizing the reliability measure, maximizing the system lifetime and minimizin...

Recent advances in automation of systematically reduced mechanisms are reported here with the aim to accelerate the development process. A computer algorithm has been developed enabling fast generation and testing of reduced chemistry. This algorithm has been used to develop various reduced mechanisms of methane-air combustion for modelling of turbulent combustion. A 10-step reduced chemistry h...

We introduce the concept of Expressive Performance Generated Composition where the initial specification for a composition comes from the details of an expressive performance. This expressive performance may have been of a previous piece or be specially produced for the composition. The expressive deviations in the performance are used to generate a meaningful interpretation of the performance ...

During the last few years the performances and therefore the complexity of the variable-speed drives as well as those of the modern power plants have considerably increased. Consequently, an optimized design of these equipments requires suitable numerical simulation tools in order to guarantee the feasibility and the performances of such equipments in steady-state or transient operation. More p...

Revenue management has been successfully implemented in the airline industry since the deregulation in 1978. There have been very few comprehensive, rigorous studies of its practices and impact, however. In this paper we examine how revenue management practices affect airline performances such as loadfactor and revenue, and how revenue management practices are implemented in different market st...

This paper proposes an simple but yet effective approach to structured parametric controller design in a linear fractional form. The main contribution consists in using structured H∞ oriented optimization tools in an original manner to either (i) construct a parametric controller or (ii) a family of controllers with varying performances. Practical and numerical issues are also discussed to prov...

DNS Tunnels are built through proper tools that allow embedding data on DNS queries and response. Each tool has its own approach to the building tunnels in DNS that differently affects the network performance. In this paper, we propose a brief architectural analysis of the current state-of-the-art of DNS Tunneling tools. Then, wepropose the first comparative analysis of such tools in term of pe...

This study evaluates operation performances of 67 international tourist hotels in Taiwan by using the Context-dependent DEA model of Date Envelopment Analysis (DEA) in order to find out the performance of these hotels and their competitive advantages. This study differentiates the levels of efficient frontier with the efficiency of each international tourist hotel. Based on the efficiency, the ...

This study investigates cross-border collaboration between beef organisations in Australia and Singapore. It aims to identify factors impacting trust and technology diffusion by gauging gaps between expected importance and perceived performance rating of the factors. The research presents results of a survey comprising 69 beef organisations from Australia and Singapore. The research identifies ...
