there have been many productive methods developed so far for optimization of multiple response surface (mrs) problems. this paper tends to review the most seminal approaches in mrs and discuss the strength and weakness of each of the approaches through existing aspects in mrs. a numerical example is included to compare results by different methods. finally some of the prominent areas for future...

The design of experiments involving more than one blocking factor and quantitative explanatory variables is discussed, the focus being on two key aspects of blocked response surface designs: optimality and orthogonality. First, conditions for orthogonally blocked experiments are derived. Next, an algorithmic approach to computeD-optimal designs is presented. Finally, the relationships between d...

In recent years, visualization has become an increasingly important tool to support exploration and analysis of larger volumes of data. Still, the interests of the users are only rarely considered. Therefore, it is the goal of this thesis to shift the needs of users into the focus. For doing so, an event-based approach to visualization is pursued. This approach allows users to specify their int...

Even the most sophisticated automatic recognition of events must often be paired with an appropriate design of the users’ interaction with those events. This paper presents three presumably typical use cases and associated interaction design proposals, which illustrate (a) how untrained users can benefit from the organization of media in terms of complex events; (b) how they can have their own ...

This paper justifies how research results can be more effectively and efficiently communicated between interested parties. In particular, it will focus on the process of seeking research results that most of the time interested parties do not know when they will be communicated. This makes the entire retrieval method a very time consuming approach and most importantly not always a successful on...

The introduction of the idea of Business Process Re-engineering in the late 1980’s has resulted in an explosion of the literature. In practice the success rates of re-engineering projects is low since the majority of the approaches are founded on a functional understanding of business systems. To be really effective however, business system transformation needs to be founded in a constructional...
