A cosmic ray detection system, consisting of standardized detector stations connected through the Internet, is described. The system can be used for detecting air showers that arrive over a wide area with correlated time. The data at each site are exchanged in (quasi) real time, which makes the system suitable for displaying cosmic ray arrivals at museums and schools.

The high computational cost of complex engineering optimization problems has motivated the development of parallel optimization algorithms. A recent example is the parallel particle swarm optimization (PSO) algorithm, which is valuable due to its global search capabilities. Unfortunately, because existing parallel implementations are synchronous (PSPSO), they do not make efficient use of comput...

Rezensionen Sinnentstellender Fehler in letztem LDV-Forum: Re-zension zu " Lexikon und Text " (Feldweg/Hinrichs) sowie " Lexikonimport, Lexikonexport " (Hoetker/ Ludewig) In der letzten Ausgabe ist auf schwer nachvollziehbare Weise in der Sammelrezension der beiden Niemeyer-Bände über Lexika (Feldweg/Hinrichs: Lexikon und Text sowie Hoetker/Ludewig: Lexikonimport, Lexikonexport) ein schwerer, s...

More and more accessible databases are available in the Web. In order to provide people a unified access to these Web databases and achieve information from them automatically, a comprehensive solution for Web database integration is proposed in this paper. After summarizing the research status in this area, the works which are the focus of my PhD thesis are presented.

In this paper we consider pulsating strings in warped AdS 6 × S 4 background, which is a vacuum solution of massive type IIA super-string. The case of rotating strings in this background was considered in hep-th/0402202 and it was found that the results significantly differs from those considered in AdS 5 ×S 5. Motivated by this results we study pulsating strings in the warped spherical part of...

Strong Confidence is a new method for setting frequentist limits that enjoys a large number of good properties[1], including that of being free from all those conceptual difficulties that have been of concern in the HEP community in past few years. Probably its most important characteristic is to comply with a form of Likelihood Principle, which is absolutely unique to the method and appears to...

The present paper contributes to the theoretical analysis of the human capital investment and participation decision of heterogeneous workers in the search and matching framework‎. ‎Its aim is to characterize the equilibrium and to identify the efficiency‎. ‎Here‎, the paper studies search equilibrium and matching to consider the participation decision of heterogeneous workers who have differen...

In this paper, we discuss the usual stochastic‎, ‎likelihood ratio, ‎dispersive and convex transform order between two parallel systems with independent heterogeneous extended generalized exponential components. ‎We also establish the usual stochastic order between series systems from two independent heterogeneous extended generalized exponential samples. ‎Finally, ‎we f...

Process monitoring using profile data remains an important and challenging problem in various manufacturing industries. Motivated by application case of motherboard testing processes, we develop a novel modeling framework for heterogeneous multivariate profiles. In this framework, graphical model is constructed to depict the complicated relationship among channels. Then channels can be reduced ...
