an infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولAn Approach to Non-standard Analysis
This note has two principal aims: to portray an essence of Non-Standard Analysis as a particular structure (which we call lim-rim), noting its interplay with the notion of ultrapower, and to present a construction of Non-Standard Analysis, viewed as a matter of mathematics, where the set A of non-standard elements of a set A – “the adjunction of all possible limits” is a “good” kind of lim-rim ...
متن کاملProof planning Non-standard Analysis
We describe how non-standard analysis can be used to prove real analysis theorems, and how these proofs can be automated using proof-planning. In particular we borrow from the constructive analysis notions of inductive partitioning, and show how transferring to the non-standard model for the reals allows us a simple proof of the correctness of partitioning algorithms for certain real analysis t...
متن کاملThe Analysis of Iran Cotton Producers’ Risk Degree Based on Non-Linear Mean-Standard Deviation Model
As regards decreasing cotton cultivation in Iran during these years, the degree of risk taken by a cotton cultivator in the agricultural part is important. The studies showed that the cotton crop yield during the past years did not have enough growth and the cotton cost product in the period of study cotton production costs, has increased. In this paper, the risk orientation of cotton cultivato...
متن کاملAn Introduction to Non-Standard Analysis and its Applications
When Newton and Leibnitz practiced calculus, they used infinitesimals, which were supposed to be like real numbers, yet of smaller magnitude than any other type of postive real number. In the 19th century, mathematicians realized they could not justify the use of infinitesimals according to their sense of rigor, so they began using definitions involving ’s and δ’s. Then, in the early 1960’s, th...
