The number of wireless communication links is witnessing tremendous growth and new standards are being introduced at high pace. However, circuit development is costly and time consuming due to mask costs and design iterations. Moreover, with ever-increasing radio standard complexity, these costs are increasing. This pleads for a Software Defined Radio approach, in which one piece of flexible ra...

in addition to its antioxidant effect, vitamin e or α–tocopherol is suggested to enhance remyelination in the animal model of non-inflammatory demyelination. in this study, the possible proliferative effect of vitamin e on human- induced pluripotent stem cell-derived neural progenitors (hips-nps) and the underlying mechanisms were investigated in vitro. nps were induced from ips cells via 3 ste...

Rough membership function defines the degree of relationship between conditional and decision attributes an information system. It is defined by where src=image/13429145_07.gif> subset src=image/13429145_08.gif> under relation src=image/13429145_09.gif> universe discourse. can be expressed in different forms like cardinality form, probabilistic form etc. In it as...

Many researchers have been working on recurrence relation which is an important topic not only in mathematics but also physics, economics and various applications computer science. There are many useful results sequence there main problem to find any term of we need all previous terms sequence. were theorems obtained relations. In this paper given special identity for generalized kth order rela...

background: despite more than a decade experience of annual student congresses in iran, major scientific writing weakness still exists in students’ abstracts submitted to the annual research congress of iran’s medical sciences students (arcimss). assessment of these abstracts can provide information on common scientific writing errors and subsequent development of abstract quality for the futur...

We determined the power and its graph simulations on discrete Poisson Chi-square distributions. There are four important steps of research methodology summarized as follow: (1) determine sufficient statistics (if possible), (2) create rejection area (UMPT test is sometime used), (3) derive formula power, (4) graphs using data (in simulation). The their curves then created <img src=image/1342768...

This paper presents a 4th order CLCL resonant converter which is suitable for constant current power supply applications. This converter is designed with Immittance characteristic with two inductors and two capacitors in resonant network. A detailed analysis and design process of a 200w converter as a constant current supply have been provided and simulation results are verified with results of...

the aim of this study was to estimate suspended sediment by the ann model, dt with cart algorithm and different types of src, in ten stations from the lorestan province of iran. the results showed that the accuracy of ann with levenberg-marquardt back propagation algorithm is more than the two other models, especially in high discharges. comparison of different intervals in models showed that r...
