فرض کنید w یک گروه و w=(s) که در آن s = {s1,. . sn | (sisj)mij = 1, 1 ? i,j ? n} و m_ij in z و به ازای هر i, m_ij= 1 در این صورت گروه w را یک گروه کاکستر می نامیم. هر یک از s_i ها را انعکاس نامیم و مجموعه ی همه ی انعکاس ها را به صورت زیر نشان میدهیم. t= {wsw-1 : w in w , sin s} هم چنین فرض کنید w یک گروه و s زیر مجموعه ی کیلی از آن باشد. در این صورت گراف کیلی w نسبت به s را که با gamma(w,...
بررسی فرار آب از مخزن بالایی دست نیروگاه تلمبه ذخیرهای سد آزاد کردستان، یکی از عوامل مهم و اثرگذار در آببندی مخزن است. در این تحقیق با توجه به مقدار نفوذپذیری دیوارهها و کف مخزن که از آزمایشهای لوژن به دست آمده، میزان نشت آب به چند روش محاسبه شده است. نتایج معادله تحلیلی ودرنیکف، روش عددی المان محدود (نرمافزار seep/w)، مقدار کل نشت آب از مخزن مورد نظر را در حالت جریان پایدار، به ترتیب بر...
Let P be a finite set of primes, and let S be a finite sequence of positive integers. This paper presents an algorithm to find the largest P smooth divisor of each integer in S. The algorithm takes time b(lg b)2+o(1), where b is the total number of bits in P and S. A previous algorithm by the author takes time b(lg b)3+o(1) to find all the factors from P of each integer in S; a variant by Frank...
Volumetric Particle Modeling. (May 2007) Brent Michael Dingle, B.S., Bradley University; M.S., Texas A&M University Chair of Advisory Committee: Dr. John Keyser This dissertation presents a robust method of modeling objects and forces for computer animation. Within this method objects and forces are represented as particles. As in most modeling systems, the movement of objects is driven by phys...
Improving the sustainability of our society requires significant change in our collective behavior. But today, individuals in our society have no regular way of seeing that collective behavior, or how their own behavior compares to it. We are creating a research network that will study how new technologies such as mobiles and visualization can encourage individuals to change their behavior to i...
The Software Engineering for Business Process Change (SEBPC) programme of the Engineering and Physical Sciences Research Council (EPSRC) is intended to support academic research which can impact the business or engineering processes in industry. The CONVERSE project was funded as part of the first round of SEBPC projects and has been running for about a year. It is intended to enable a major co...

Previous studies have revealed surprising and persistent cross-cultural variations in overconfidence, whereby respondents in some Asian cultures (e.g., Chinese) exhibit markedly higher degrees of overconfidence than respondents in other cultures (e.g., in the United States and Japan). Most of those demonstrations have entailed general knowledge tasks (e.g., answering We are especially grateful ...
Masked translation priming between languages with different scripts exhibits a marked asymmetry in lexical decision, with much stronger priming from L1 to L2 than from L2 to L1. This finding was confirmed in a lexical decision task with Chinese–English bilinguals who were late learners of English. Following a suggestion made by Bradley (1991), the experiment was repeated using a speeded episodi...
sparked my interested in this research and who have remained a constant source of information throughout the study. I also wish to thank Shelly Bland for her hard work and assistance in gathering and entering the data for this study. I would like to thank the Attention and Working Memory Lab at Georgia Tech for the use of their cognitive tasks and for their assistance in contacting participants...
