This paper describes an audio digital signal-processing toolkit that the authors develop to sup-plement a lecture course on digital signal processing (DSP) taught at the department of Electrical and Electronics Engineering at the University of Rwanda. In engineering education, laboratory work is a very important component for a holistic learning experience. However, even though to-day there is an increasing availability of programmable DSP hardware that students can largely benefit from, many poorly endowed universities cannot afford a costly full-fledged DSP laboratory. To help remedy this problem, the authors have developed C#.NET toolkits, which can be used for real-time digital audio signal processing laboratory. These toolkits can be used with any managed languages, like Visual Basic, C#, F # and managed C++. They provide frequently used modules for digital audio processing such as filtering, equalization, spectrum analysis, audio playback, and sound effects. It is anticipated that by creating a flexible and reusable components, students will not only learn fundamentals of DSP but also get an insight into the practicability of what they have

the study is to specify whether socio-demographic factors and physical activ-ity result in differences in subjective assessment of life in women diagnosed with breast cancer. Material and methods: The study group consisted of 145 women who had been diagnosed with breast cancer. The women had undergone radical surgery, chemotherapy and radiotherapy. The participants filled in an anonymous questionnaire which contained a num-ber of detailed questions relating to their socio-demographic standing, life style, condition and the current self-assess-

ACKNOWLEDGEMENTS This report shows some of the results of some preliminary analysis aimed at designing a better distribution of targeted programs at the regional level. We have benefited from several discussions with the people at WFP Dhaka, in particular with

The term photocatalysis is often used to refer to processes carried out in the presence of photoactive materials and aimed toward wastewater decontamination or water splitting for the generation of hydrogen as a fuel. However, the idea that photocatalysis can provide an alternative to more conventional synthetic pathways has been gradually emerging [1-13]. In its broadest sense, photocatalysis for synthetic purposes concerns the use of light to induce chemical transformations of organic or inorganic substrates that are transparent in the wavelength range employed. The radiation is absorbed by a photocatalyst, whose electronically excited states are able to trigger the chemical reactions of interest. The overall process can be considered photocatalytic when i) the photoactive species is regenerated in its initial state at the end of a reaction cycle, just as happens in thermal catalysis; ii) the photocatalyst is consumed less than in stoichiometric amounts, while light is a stoichiometric reagent. Selectivity is a key issue in photocatalytic processes aimed at the

Multi-objective evolutionary algorithms which use non-dominated sorting and sharing have been mainly criticized for their (i) O(MN computational complexity (where M is the number of objectives and N is the population size), (ii) non-elitism approach, and (iii) the need for specifying a sharing

Multi-objective evolutionary algorithms which use non-dominated sorting and sharing have been mainly criticized for their (i) -4 computational complexity (where is the number of objectives and is the population size), (ii) non-elitism approach, and (iii) the need for specifying a

and prospective users of these techniques are clam-oring more and more loudly for a “methodology ” of object-oriented software construction- or at least for some methodological guidelines. This article presents such guidelines, whose main goal is to help improve the reliability

Abstract. We present a novel method for generic visual categorization: the problem of identifying the object content of natural images while generalizing across variations inherent to the object class. This bag of keypoints method is based on vector quantization of affine invariant descriptors

Most current approaches to concurrency control in database systems rely on locking of data objects as a control mechanism. In this paper, two families of nonlocking concurrency controls are presented. The methods used are “optimistic ” in the sense that they rely mainly on transaction backup as a
