Abstract We propose a method to establish time reversal symmetry violation at future neutrino oscillation experiments in largely model-independent way. introduce general parametrization of flavour transition probabilities which holds under weak assumptions and covers large class new-physics scenarios. This can be used search for the presence T-odd components by comparing data different baseline...
In this article we examine the impact of daily trade turnover on the day-of-the-week effect in emerging stock markets. The empirical analysis was made by using Vilnius Stock OMX equities return data. The main method suggested for analysis was based on formation of three portfolios with equities having low, medium and high daily turnover. By applying traditional statistical research methods, suc...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
تقریبا" 50 در صد موارد ناباروری به فاکتورهای مردانه مربوط میشود .امروزه انجماد اسپرم انسان برای افزایش میزان موفقیت در روشهای کمک باروری ،جهت ایجاد بانک اسپرم برای مردان در معرض شیمی در مانی انجام میگیرد . هدف از این مطالعه ، بررسی اثر انجماد شیشه ای بر روی پارامترهای تحرک، مورفولوژی، قابلیت حیات، شمارش( غلظت ) و نیز میزان آپوپتوز اسپرم بعد از ذوب می باشد. روش ازمایش: نمونه های سیمن 34 بیما...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
عوامل زیادی در عملکرد آزمونی زبان آموزان در متن یادگیری زبان موثر می باشد.این تحقیق تلاشی است در زمینه بررسی نقشی که سبک های شناختی و شخصیتی بر عملکرد یادگیرنده های زبانی در سوالات c-test z-test و تست های چند گزینه ای دارد. در این تحقیق سعی شده است تا نقش درون گرایی، برون گرایی، تکانشی و فکری بودن بر روی عملکرد شرکت کنندگان در این آزمون ها بررسی شود. به منظور دستیابی این هدف 212 یادگیرنده زبان ...
