In this paper, we present a new algorithm for the design of orthonormal two-band rational filter banks. Owing to the connection between iterated rational filter banks and rational wavelets, this is also a design algorithm for orthonormal rational wavelets. It is basically a simple iterative procedure, which explains its exponential convergence and adaptability under various linear constraints (...

in this report, we describe a procedure for in-silico design of a novel haloalkane dehalogenase protein that exhibits luciferase property which can be potentially used in biosensor applications. from a pdb blast search, the selected haloalkane dehalogenase (pdb code: 1ede) had a close structural homology with a lucifearse (pdb code: 2psj chain a) sharing an identity of 33%. initially, the amino...

A new discipline, Usability Design, is introduced as an extension to Rational Unified Process (RUP). The aim is to make RUP more user-centred. The discipline springs out of best practices for user-centred design and contains activities that have been carefully tested. Five new roles are introduced to take responsibility for the different activities. An example is given to show the content of th...

We analysed four Rational Unified Process (RUP) projects in Switzerland that identified themselves as following a user-centred approach. Grounded theory served for analysis of 12 interviews with software developers, project managers, and UI specialists. For each professional group we analysed their work context, motivations, work practices, and strategies used to overcome the obstacles to user-...

3D virtual worlds are networked environments designed using the place metaphor. 3D virtual worlds as Computer-aided Design (CAD) tools have shown promising potentials in areas such as design simulation, distant team works as well as interdisciplinary design collaboration. Recent developments in collaborative 3D virtual worlds focus on interactivity, flexibility and adaptability. Rather than cre...

The importance of sharing designer’s intention (socalled design rationale, DR) is widely recognized. This paper focuses on modeling DR of supplementary functions which prevent undesirable states of a required function (e.g., malfunctions). Although they do not essentially contribute to the achievement of the required function, they play an important role in design and design improvement of arti...

One perspective of a design process in the engineering design community is that it is largely a process marked and defined by a series of decisions. The fundamental assumption in most developed design decision support methodologies is that decision makers make rational choices; that is, choices that maximize the payoff for the predicted outcome. Decisions that do not maximize the predicted payo...

Mechanism design (MD) has recently become a very popular approach in the design of distributed systems of autonomous agents. A key assumption required for the application of MD is that agents behave rationally in the mechanism or game, since this provides the predictability of agent behavior required for optimal design of the mechanism. In many cases, however, we are confronted with the intract...

Various schemes have been proposed for creating rational surface patches with a variable number of sides. Although these schemes appear to be unrelated, they all produce surface parameterizations that have parameter values for which the numerator and denominator of the deening rational functions vanish simultaneously. These parameter values are base points of the rational parameterization. This...
