در این پایان نامه ابتدا در مورد توابع تک ارز و خواص هندسی آنها و همچنین رابطه ئ این خواص هندسی با شرایط معادل خواص تحلیلی را مطالعه می کنیم. سپس زیر کلاسهای k وs^* (?) که شامل توابع نزدیک به محدب در دیسک واحد u است را تعریف می کنیم وبه کمک خواص پیروی و مشتق توابع تحلیلی خواص شمولیت، برآورد ضریب وقضایای پوششی وچند خاصیت دیگر را در مورد زیر کلاس k_s (?,a,b) مورد بحث وبررسی قرار می دهیم. کارهای ا...
in one pole of the continuum of language learning, theoreticians and practitioners traditionally consider english as english as a second language or english as a foreign language. however, in the other pole of this continuum where english is thought of as the most effective tool for international communication, it is referred to as a lingua franca. those who favor an approach to english growing...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
severe hepatic failure accounts for many deaths and raises medical costs each year worldwide. currently, liver transplantation is the most common therapeutic option for patients with end-stage chronic liver disease. due to decrease in the number of organ donors, many in need of transplantation continue to remain on the waiting list. hepatic tissue engineering is a step toward alleviating the ne...
We describe an ontology for mathematical modeling in engineering. The ontology includes conceptual foundations for scalar, vector, and tensor quantities, physical dimensions, units of measure, functions of quantities, and dimensionless quantities. The conceptualization builds on abstract algebra and measurement theory, but is designed explicitly for knowledge sharing purposes. The ontology is b...
• Even after the rigorous theoretical foundations of probability theory were laid down, it was not accepted by all in the scientific and mathematics communities as a legitimate field of mathematics. The primary controversy was one borne out of metaphysical concerns how could the mathematical reality underlying nature be written in the language of chance? Even today, there are researchers who cr...
Some new ideas in teaching mathematics to engineering students and the implementation of these ideas into the teaching of mechanical engineering students at Brighton University are discussed. The importance of explaining to the students why knowledge of mathematics is essential for their future practical work is emphasized. Mathematics is a language for expressing physical, chemical and enginee...
This paper examines three ideas: First, the traditional relationship between a science, the mathematics it uses and the engineering based on it. Second, the nature of (software) computer science, which may not be a science at all, and its unusual use of mathematics. And finally, the nature of software engineering, its relationship with computer science, and its use of mathematics called ‘formal...
