Design knowledge belongs to intellectual property, presented in three main types: (1) Serviceable Design Knowledge (SDK), (2) Intangible Design Knowledge (IDK), and (3) Tangible Design Knowledge (TDK). These three types of design knowledge are respectively generated in three successive creation development stages, namely the early design strategy stage, the intermediate design process stage, an...

This work presents a new control method to track the maximum power point of a grid-connected photovoltaic (PV) system. A backstepping controller is designed to be applied to a buck-boost DC-DC converter in order to achieve an optimal PV array output voltage. This nonlinear control is based on Lyapunov functions assuring the local stability of the system. Control reference voltages are initially...

In the design of railway track layouts, there are only a small number of geometric configurations that are used in practice, and a number of constraints as to how those configurations can be fitted together to create a whole layout. In order to solve these problems, we construct a Haskell combinator library. The library has been used for the design of real-world track layouts.

Design, evaluation and refinement of intelligent systems was a popular topic at FLAIRS 2008. More and more authors have realized that the lack of systematic methods and formal techniques for the design, the evaluation, and the refinement are often important reasons for not using AI systems in practice. The first contributions in this field were limited to classical AI approaches such as rule-ba...

In an observational study using an eye-tracker, subjects were presented with a modeless cookie choice dialog preceding a short survey on Internet privacy. Subjects were later asked whether they believed ad trackers were present on the site or not. 41% believed there either were or were not ad trackers on the site based on not clicking ”allow” or ”block”, respectively. These results suggest that...

Competitive and recreational sport on artificial ice tracks has grown in popularity. For track design one needs knowledge of the expected speed and acceleration of the luge on the ice track. The purpose of this study was to develop an approximate simulation model for luge in order to support the initial design of new ice tracks. Forces considered were weight, drag, friction, and surface reactio...

This paper focuses on the tracking and synchronization problems of hyperchaotic systems based on active backstepping method. The method consists of a recursive approach that interlaces the choice of a Lyapunov function with the design of feedback control. First, a nonlinear recursive active backstepping control vector is designed to track any desired trajectory in hyperchaotic Wang system. Furt...

Michigan State University Serious Game Design Track. This site describes MSU’s new track in TISM. The homepage includes information on MSU game design programs, the Meaningful Play Conference, interviews with alumni designing serious games, and other materials of interest to educators in the field.
