It is the purpose of this study to develop an economical Robust design methodology for micro-scale secondary flow control in compact inlet diffusers. To illustrate the potential of economical Robust Design methodology, two different mission strategies were considered for the subject inlet, namely (1) Maximum Performance, and (2) Maximum HCF Life Expectancy. The Maximum Performance mission maxim...

TECHNICALNOTES are shortmanuscript s describing new developments or important results of a preliminary nature. TheseNotes cannot exceed sixmanuscript pages and three Ž gures; a page of text may be substituted for a Ž gure and vice versa. After informal review by the editors, they may be published within a few months of the date of receipt. Style requirements are the same as for regular contribu...

The geomorphology and the climate represent the two elements that form the basis of biotope diversity in the Lesser Antilles. They are home to many plant species expressing various combinations. Irrespective of their morphogenetic phases and phytocenotic evolution stages, the taxa occupy specific sites. These sites named installation and expansion site represent volumes (epigeous and hypogeous ...

A physically interpretable model of an experimental strip guidance installation, operated at Hoogovens Research and Development in the Netherlands, is derived by means of system identification. This process consists of an offset pivot guide steering roll with five degrees of freedom, four cylindrical guide rolls, and one driving roll. In this experimental installation, an endless steel strip is...

The aim of this paper is to present the design and evaluation process of a Fuzzy PD controller for an experimental platform for buildings based on a fieldbus system. The experimental platform consists of interconnected nodes (sensors and actuators), using the European Installation Bus (EIB) fieldbus network infrastructure. A “smart node” consisted of a personal computer, containing custom contr...

The production process of pre-cast concrete installation is analyzed to investigate possible ways for onsite productivity improvement. Although manufactured construction enjoys higher quality and productivity, it is observed that it suffers delays compared to site built construction. Delay causes and respective severity are analyzed for improvement. Firstly, the production process is investigat...

In this paper I analyze the interaction between sound and the visual arts as well as its development through the acoustic space and time. In other words, I am trying to understand the aesthetic implications of the sound sculpture and sound installation disciplines. Nevertheless, in order to understand the main characteristics of this relatively new media, we need first to consider some importan...

Users often install applications from untrusted sources. Alcatraz is a system that provides isolation of a system from potentially untrustworthy user programs. However, we find performance and functionality concerns with Alcatraz. Nevertheless, Alcatraz demonstrates the feasibility of one-way isolation of user programs. During a port of Alcatraz to a modern commodity operating system, Mac OS X,...

PURPOSE: To develop a method for direct measurement, using anatomic specimens, of the precision of MR-guided stereotaxic location and to describe its application to a 1.5-T MR unit with a Leksell stereotaxic frame. METHODS: Small pieces of gel foam ( 1 X 1 X 1 mm), soaked in gadopentetate dimeglumine, were stereotaxically introduced into formalin-fixed human heads using a Leksell D (three exper...
