A new style of charge-separation position-sensitive detector has been tested which has similar cost benefits as other charge-separation devices but has an error-awareness capability to provide an increased collection rate. The wedge-on-wedge anode is similar to the wedge-and-strip anode except that the four electrodes possess both wedge and strip character. This provides additional charge infon...

An interaction of plasma flow with an arc-anode attachment in a dc arc plasma torch was investigated. Statistical processing of the photographic images of plasma jet was used for analysis of an effect of the anode attachment on structure and stability of plasma flow. Deflection, flattening and flutter of the plasma jet was found to be caused by disturbing effect of the arc-anode attachment.

This review divides naturally into sections covering the war and postwar periods. Parts 1 and 3 give surveys of the work which came within the purview of the Aeronautical Research Committee until its reconstitution as a Council in 1945, and of the Council since that date, respectively. Part 2 describes matters concerned with the formation of the Council. (iv) A numerical list of papers publishe...

Iterative mockup prototyping is a widely used way of tackling the problem requirements change during product development. This usually combined with use Likert-style scales for quantitative feedback on each iteration. However, there are inherent limitations in explanatory power running from negative to positive values (e.g. “strongly dislike“ like”). In this ar...

The aim of this study was to present a usability evaluation conducted under the User Experience (UX) perspective of a sonificated search engine called WhatsOnWeb, an accessible application based on sophisticated graph visualization algorithms which conveys datasets using graph-drawing methods based on semantically clustered data. Starting with evidence from an amodal system processing spatial r...
