This paper describes the use of statechart notation to design the pattern of behavior that a user will have when interacting with a learning bean. The larger context of a learning bean and the stakeholders that are involved in its deployment and use are also introduced, two beans are briefly described and the results of a user trial presented.

Product family configuration design has been recognized as a promising dimension for implementing the assembly-to-order production strategy under mass customization environments. With a family of configuration design alternatives derived from a configuration space, product family configuration design evaluation is usually performed to select the “best” configuration design that meets customer v...

We report on a new game design where the goal is to make the stereoscopic depth cue sufficiently critical to success that game play should become impossible without using a stereoscopic 3D (S3D) display and, at the same time, we investigate whether S3D game play is affected by screen size. Before we detail our new game design we review previously unreported results from our stereoscopic game re...

Design has been recognized for a long time both as art and as science. In the sixties of the previous century design-oriented research began to draw the attention of scientific researchers and methodologists, not only in technical engineering but also in the social sciences. However, a rather limited methodology for design-oriented research has been developed, especially as to the social scienc...

This paper discusses a metrics approach for analyzing software designs that helps designers engineer quality into the design product. These metrics gauge project quality as well as design complexity at all times during the design phase. The metrics are developed from primitive design metrics which are predictive, objective and automatable. The architectural design metrics used are comprised of ...

PURPOSE Single-arm phase II trials may not be appropriate for testing cytostatic agents. We evaluate two kinds of randomized designs for the early development of target-based cytostatic agents. METHODS We compared power of the randomized discontinuation and upfront randomization designs under two models for the treatment effect of targeted cytostatic agents. RESULTS The randomized discontin...

We describe a search strategy that may be useful for a class of design problems by developing an example from cancer radiation treatment planning. This application problem involves typical features of design problems such as constraints, optimality, a large search space with continuously varying parameters as well as discrete (non-numeric) parameters. There is no known method of comparing eleme...

This thesis presents the design and development of several tactile displays, as well as their eventual integration into a framework of tactile and kinesthetic stimulation. As a basis for the design of novel devices, an extensive survey of existing actuator principles and existing realizations of tactile displays is complemented by neurobiological and psychophysical findings. The work is structu...

Visual overviews of tables of numerical and categorical data have been proposed for tables with a single value per cell. In this paper we address the problem of exploring tables including columns consisting of distributions, e.g. the distributions of movie ratings or trust ratings in recommender systems, age distributions in demographic data, usage distributions in logs of telephone calls etc. ...

The increasing popularity of automated tools for software and hardware verification puts ever increasing demands on the underlying decision procedures. This paper presents a framework for distributed decision procedures (for first-order problems) based on Craig interpolation. Formulas are distributed in a lazy fashion, i.e., without the use of costly decomposition algorithms. Potential models w...
