all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
This paper extends the Brander-Spencer (1985) model by considering market uncertainty, exploring nonlinear policy, and examining ̄rms' choices of strategic variables. By investigating the interrelationship between trade policy and market conduct, we ̄nd that unlike the oftenstudied linear policy, a nonlinear policy can in°uence the domestic ̄rm's choice of strategic variables and hence alter th...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
هویت, شکل دادن و بازنمایی آن در گفتمان, توجه بسیاری از محققان این رشته را به خود جلب کرده است. تحقیق حاضر بر شکل دادن به هویت جنسیتی هشت تن از دانشجویان ایرانی مشغول به تحصیل در دوره کارشناسی ارشد از طریق بررسی روایات آنان از تجربیات شخصی, متمرکز شده است. تحلیل داده ها در این تحقیق مشتمل بر سه بخش است: بخش اول شامل کدگذاری موضوعی روایات است که بر اساس آن هویت جنسیتی شرکت کنندگان در تحقیق بر اسا...
In this issue, “25 Years Ago” revisits the article “Controlling Buildings: A New Frontier in Feedback,” by B.F. Spencer Jr. and Michael K. Sain IEEE Control Systems Magazine , vol. 17, no. 6, pp. 19–35, 1997. Below is an excerpt from article.
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
We now move on to a very interesting and powerful technique in combinatorics, called the probabilistic method. There is an excellent (really excellent!) textbook written by Noga Alon and Joel Spencer [AS16]. In fact, most materials that we will cover are from [AS16]. The method works as follows. Our goal is to prove the existence of certain object or structure with desired properties. We start ...
We give an account of the construction of exterior differential systems based on the notion of tableaux over Lie algebras as developed in [33]. The definition of a tableau over a Lie algebra is revisited and extended in the light of the formalism of the Spencer cohomology; the question of involutiveness for the associated systems and their prolongations is addressed; examples are discussed.
