We consider the following problem for wireless ad hoc networks: assume n nodes, each capable of communicating with nodes within a radius of r, are distributed in a ddimensional region of side l; how large must the transmitting range r be to ensure that the resulting network is connected? We also consider the mobile version of the problem, in which nodes are allowed to move during a time interva...

Even in case of the Brownian motion as most natural rate of return model it appears too difficult to obtain analytic expressions for most risk measures of constant continuous annuities. In literature so-called comonotonic approximations have been proposed but these still require the evaluation of integrals. In this paper we show that these integrals can sometimes be computed, and we obtain expl...

Most failures of linear electron accelerators (LEA) are caused by malfunctions in the systems of RF-feeding, modulators and clystrons. And a great part of malfunctions lead to the increased dispersion of amplitudes of output signals of the system. In this paper we consider the algorithms of failure prediction based on some indication functions and the use of these algorithms in the LEA control ...

For the past six years, we have been teaching a neuroscience for non-science majors course titled "From Botox to Behavior: Neuroscience for non-scientists." The primary objectives for this course are to create science literate students using neuroscience concepts as the foundation. The evidence from our course assessments suggest that the students are learning fundamental concepts and developin...

A method of evaluating the thermal focal length of nonlinear crystal via transmission spectrum of a swept cavity (TSSC) is presented. By recording the resonant point offset of the TSSC, the thermal focal length can be successfully measured. Furtherly, by distinguishing the absorption of ultraviolet (UV) laser and UV laser induced infrared absorption (ULIIRA), it is clear that the ULIIRA is the ...

Construction of a recognizer in a new target language usually involves collection of a comprehensive database in that language as well as manual annotation and model training. For rapid development of new language recognizer, we propose (1) substituting target language phoneme models by source language phoneme models trained previously; and (2) adapting target language phoneme models from sourc...

This paper presents an application of BAT algorithm for multi-objective optimization problem in power system. Considering the environmental impacts that grow from the emissions produced by fossil-fuelled power plant, the economic dispatch that minimizes only the total fuel cost can no longer be considered as single objective. Application of BAT algorithm in this paper is based on mathematical m...
