Based on the private message service described in [4] we show efficiency improvements of that private message service in the computational setting. Regarding an attacker which may control all but one of the queried servers we describe a private message service with a total communication complexity of blinded read between client and private message service of n bit upstream and k bit downstream,...

Contextual Inquiry is a method developed by Beyer and Holtzblatt for grounding design in the context of the work being performed. In this paper, we adapted the method successfully for analyzing pre-existing videotaped presentations. Our goal was to find improvements for a slide presentation program currently in development, called 'SlideShow Commander.' Contextual Inquiry provided us with meani...

In this type-II demo, we introduce SIDE (the Summarization Integrated Development Environment), an infrastructure that facilitates construction of summaries tailored to the needs of the user. It aims to address the issue that there is no such thing as the perfect summary for all purposes. Rather, the quality of a summary is subjective, task dependent, and possibly specific to a user. The SIDE f...

The growth of the Internet has encouraged the creation of visually rich and perceptual interfaces on personal computers and mobile devices. Organisations develop websites for various purposes, and over time, the features and functions of websites have evolved significantly. Since website quality affects organisational performance, it is important to be able to assess the efficacy of websites. H...

Based on data from firms in the personal computer industry, we study the effect of new product introductions on three key drivers of firm value: profit rate, profit-rate persistence, and firm size as reflected in asset growth. Consistent with our theoretical development, we find that new product introductions influence profit rate and size; however, we find no effect on profit-rate persistence....

We developed an application for learning the finger alphabet of Swiss German Sign Language. It consists of a user interface and a recognition algorithm including the Kinect sensor. The official Kinect Software Development Kit (SDK) does not recognize fingertips. We extended it with an existing algorithm.

1998 ABSTRACT i ABSTRACT Interest in the World Wide Web (WWW or web) is growing at a rapid pace. As more organisations and individuals seek a presence on the WWW, the size and complexity of web pages is growing at a rapid pace. However web page development is still predominantly performed in an ad hoc manner, often resulting in cost overruns, quality degradation, and maintenance problems. Altho...

Software engineering continues to develop methods for process improvement and quality. The Personal Software Process is one way to introduce software engineers to aspects of process tracking, assessment and improvement. In this paper, we describe the software tools that we’ve constructed to support the planning and postmortem of software activities. We describe an approach that allows the perso...

We have developed a prototype vision system maintaining conventional data transfer speeds that can achieve both high resolution and high-speed over 1000Hz feedback rate by using “Mm-Vision” concept, the technique of intelligent selection of pixel of interest for reducing the amount of output data. To verify the effectiveness of the system and its concept, some high-speed image processing experi...

Usually collecting data regarding software requires a lot of time and effort. Moreover, these data are often unusable because are affected by too many errors especially when these measurements are most important: during high stressing periods, as instance because of an approaching important deadline. An automated tool to collect such data in a noninvasive way should partially solve the problem ...
