Two experiments were designed to replicate and extend [Lindgaard et al.’s, 2006. Attention web designers: you have 50ms to make a good first impression! Behaviour and Information Technology 25(2), 115–126] findings that users can form immediate aesthetic impression of web pages, and that these impressions are highly stable. Using explicit (subjective evaluations) and implicit (response latency)...

Windows CE 3.0, also known as Pocket PC for palm-sized devices, is becoming increasingly popular among professionals and corporate enterprises. It is estimated that by 2004 Windows CE will have a share of 40% of the marketplace for palm-sized devices. The documented vulnerabilities against a major competitor of WinCE, Palm, and the proliferation of palm-sized devices highlight the need for secu...

Digital libraries have great potential to improve the educational experience. There are a wide variety of such repositories, especially those that focus specifically on education. However, a survey of existing work shows relatively few that have both a narrow subject focus and ample affordances for content browsing. We present our prototype design and implementation for the HumanCentered Comput...

Previously, it had been found that texture-coding was ineffective at reducing search time (Perlman & Swan, 1993). In the experiment reported here, 16 subjects searched for blank-, color-, texture-, and density-coded targets of varying complexity in a naturalistic task. The data showed that all non-blank methods were significantly and about equally more effective at reducing search time than bla...

Sheet metal forming problems are typical in nature since they involve geometry, boundary and material non-linearity. Cup drawings involves many parameters like punch and die radius, clearance, lubrication, blank holding force and its trajectories etc. So designing the tools for cup drawing involves a lot of trial and error procedure. To reduce number of costly trial error steps, the process can...

Helical gears are commonly used in industry as they have advantages of higher power density, quieter operation etc., compared to spur gears. Conventional gear design is based on various design criteria, including durability and bending strength load rating. In recent times, fracture failure modes are gaining importance in addition to conventional failure modes. Stresses due to operating fatigue...
