This study reports on a case study examining the impact of emergency vehicle preemption on closely spaced arterial traffic signals. The study was conducted on SR 26 a principal arterial and main thoroughfare connecting Interstate 65 with US 52 on the East side of Lafayette, Indiana. This study examined four coordinated intersections along SR 26 using seven preemption paths and three different t...

This article introduces a concept for evaluating integrated knowledge and co-operation platforms which was derived from systematic examination of computer supported co-operative work (CSCW) and knowledge management systems and from research of available evaluation approaches to CSCW and knowledge management systems. It consists of various evaluation perspectives (individual, group, organisation...

The Cipher Block Chaining (CBC) mode of encryption was invented in 1976, and it is currently one of the most commonly used mode. In our previous research works, we have proven that the CBC mode of operation exhibits, under some conditions, a chaotic behavior. The dynamics of this mode has been deeply investigated later, both qualitatively and quantitatively, using the rigorous mathematical topo...

This paper investigates the relationship between oculomotors, which consist of eye-movement and pupillary change, and the traditional subjective index for “usability”, to determine the possibility of evaluating HumanComputer Interaction (HCI). An evaluation experiment was conducted by operating a target on a computer display using input devices: mouse, keyboard and key pad. The results show the...

A prospective randomised double-blind controlled trial was carried out to evaluate the place of a single dose of triazolam, flurazepam, and placebo on the evening before an elective operation in 96 patients. Features of sleep were recorded by patients and nurses on questionnaires. Onset of sleep was delayed and duration of sleep reduced in two-thirds of patients allocated placebo compared with ...

This chapter describes a methodology for analyzing some of the manufacturability aspects of machined parts during the design stage of the product development cycle, so that problems related to machining can be recognized and corrected while the product is being designed. Starting with the CAD design for a proposed part, our basic approach is to systematically generate alternative operation plan...

Ahatcaet Factors involved in construction and utilization of an inexpensive, rapid-response potentiostat with 50 mA current capabilities are discussed. The potentiostat can be used with ancillary units, eg function generators, for a variety of rapid perturbation approaches, eg cyclic voltammetry at scan rates to 4000 V/s or greater, potential-step chronoamperometry with data acquisition after 4...

We examine residual evaluation, perhaps the most basic operation in numerical simulation. By raising the level of abstraction in this operation, we can eliminate specialized code, enable optimization, and greatly increase the extensibility of existing code.
