Courses covering analytical methods for materials characterization are part of the educational program in many academic faculties, particularly in applied physics and chemistry. Employment of multimedia techniques in the presentation of the subject is increasingly accepted and even demanded by students as the required hardware and software becomes affordable and widely available at reasonable q...

Other papers in this volume describe some of the results which have come from the HDF data. I describe here several types of observations in the infrared which can take us beyond the redshifts probed by the HDF. Although I have split this paper into two main sections, one covering emission-line techniques and the other covering continuum-based techniques, it should be noted that all of these su...

In this paper, three types of (philosophical, optimistic and pessimistic) multigranulation single valued neutrosophic (SVN) covering-based rough set models are presented, and these three models are applied to the problem of multi-criteria group decision making (MCGDM).Firstly, a type of SVN covering-based rough set model is proposed.Based on this rough set model, three types of mult...

We survey techniques for solving binate covering problems, an optimization step often occurring in logic synthesis applications. Standard exact solutions are found with a branchand-bound exhaustive search, made more efficient by bounding away regions of the search space. Standard approaches are said to be explicit because they work on a direct representation of the binate table, usually as a ma...

This thesis tries to expand the frontiers of approximation algorithms, with respect to the range of optimization problems as well as mathematical tools for algorithms and hardness. We show tight approximabilities for various fundamental problems in combinatorial optimization. We organize these problems into three categories — new and applied constraint satisfaction problems (CSP), hypergraph co...

after mentioning the main differences between malaria control and malaria eradication, it is suggested that all anti–malaria activities in iran should be renamed as malaria control. applied research in malaria is identified into four categories covering the following subjects. 1- malaria parasites and anti-malaria drugs. 2- malaria vectors. 3- malaria in the community. 4- use of epidemiological...

Recently, sample complexity bounds have been derived for problems involving linear functions such as neural networks and support vector machines. In many of these theoretical studies, the concept of covering numbers played an important role. It is thus useful to study covering numbers for linear function classes. In this paper, we investigate two closely related methods to derive upper bounds o...
