The following problem is considered: Maximize the output energy of a linear time-invariant channel, given that the input signal is time and amplitude limited. It is shown that a necessary condition for an input U to be optimal, assuming a unity amplitude constraint, is that it satisfy the fixed-point equation U = sgn [F(u)], where the functional F is the convolution of U with the autocorrelatio...
در شبکه های بی سیم، تخصیص مناسب امکانات مستلزم طراحی الگوریتم های مسیریابی، کنترل نرخ ورودی، زمان بندی، تخصیص کانال و کنترل توان می باشد. اگر این الگوریتم ها هر یک به صورت جداگانه طراحی شوند و سپس در شبکه مورد استفاده قرار گیرند، تخصیص امکانات به صورت غیر بهینه خواهد بود و علاوه بر آن، چندباره کاریهای غیر ضروری در پیاده سازی این الگوریتم ها رخ می دهد. حال اگر الگوریتم های فوق بطور مشترک با هم ط...
this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
ساختار پایه ای به صورت پردازنده فازی آنالوگ دو-ورودی یک - خروجی با قابلیت پیکربندی دوباره بوسیله پالس های دامنه محدود آنالوگ و تولید کننده قواعد با استفاده از مدارات ساده با ترانزیستورهای mos ارائه شده است. یک روش ساده غیر فازی سازی با استفاده از مفهوم غیر فازیس سازی ماکزیمم پیشنهاد شده است شبیه سازی های hspice روی زیر مدارهای ساختار ارائه شده انجام شدهاست. برای کنترل سطح یک تانکر آب نیز شبیه س...

one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
in this paper, the problem of decentralized model reference adaptive control (mrac) for a class of large scale systems with time varying delay in interconnected term and input and state delays is studied. to compensate the effect of input delay indirectly, a smith predictor built on. to handle the effects of the time delays in input, the adaptive controller part includes two auxiliary dynamic f...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Abstract By reviewing economic performance, two main phenomena could be identified: The first phenomenon is prior to the third wave of the Industrial Revolution in which limited resources are the predominant input; in other words, physical and natural resources are much more credited than human resources. The second phenomenon resonates with the third wave of industrial revolution to the presen...
