Solving optimal control problems for many different scenarios obtained by varying a set of parameters in the state system is a computationally extensive task. In this paper we present a new reduced framework for the formulation, the analysis and the numeri ...
In this paper, we study the performance of IPOP-saACM-ES, recently proposed self-adaptive surrogate-assisted Covariance Matrix Adaptation Evolution Strategy. The algorithm was tested using restarts till a total number of function evaluations of 10^6D was r ...
Bringing flexibility and extensibility into Learning Management Systems) is crucial because it gives teachers and students a free choice of technologies and educational materials they want to use for their courses. The paper presents a solution via enablin ...
Modern social media systems are geared to serving weak ties: informal collections of individuals acting in relative isolation. But what about strong ties: the family and friends who form life's inner circle? More and more people are living apart. Can techn ...
Gold and rhodium nanoparticles stabilized by a cationic polymer can be readily modified by anion exchange to afford nanoparticles that may be dispersed in a wide range of organic solvents and ionic liquids. The catalytic activity of the Rh nanoparticle dis ...
This paper investigates the acceptability of using social media for collaborative learning in the context of higher education. A social media platform, Graasp, is used to support students’ learning activities in a project-based course. An evaluation of Gra ...
Within the research project KOLINE a cooperative system for urban road transport is developed. Its traffic related goals are to reduce travel time and fuel consumption as well as noise and pollutant emissions. The herein described evaluation shall determin ...
We present a novel microfluidic approach for on-line analysis of cell metabolism by simultaneous measurement of two important indicators (glucose and lactate) in a small volume (100 µl) of cell-culture medium. The in-vitro study of cell metabolism is espec ...
Various practical applications of the average (A) and difference (D) of Friedel opposites are described. Techniques based on the resonant-scattering contribution to Friedel differences are applied to see whether a crystal is centrosymmetric or not, and to ...
Summary: NoRSE was developed to analyze high-frequency datasets collected from multistate, dynamic expts., such as mol. adsorption and desorption onto carbon nanotubes. As technol. improves sampling frequency, these stochastic datasets become increasingly ...
