در محیط محاسبات فراگیر، تمام وسیله هایی که قصد برقراری ارتباط با یکدیگر را دارند با رویدادها سر و کار دارند. به همین دلیل، کشف سرویس ها و مدیریت رویدادها در این محیط از حساسیت و پیچیدگی محسوسی برخوردار است. با توجه به اهمیت موضوع، هدف این رساله ارائه ی شیوه ایست که با استفاده از پایگاه داده ی فعال و به کارگیری قوانین eca (event, condition, action)، پیچیدگی رویدادهای بین وسیله ها را کاهش داده ...

اصولی که می بایست در روشهای عددی از جمله روش حجم کنترل مورد توجه قرار گیرد تا یک مسئله فیزیکی بطور واقعی مدل سازی گردد عبارت است از: تعیین درست معادلات حاکم بر مسئله، گسسته نمودن معادلات به روابط جبری صحیح و تهیه الگوریتم حل. آز آنجا که در الگوریتم حل چگونگی حفظ پیوستگی میدان و ارضای قانون بقای جرم مورد توجه قرار می گیرد تدوین آن از اهمیت ویژه ای برخودار است . در این پرژوه ابتدا به معرفی معادلا...

In this research, behaviour of clayey soils under triaxial loading is studied using Neural Network. The models have been prepared to predict the stress-strain behaviour of remolded clays under undrained condition. The advantage of the model developed is that simple parameters such as physical characteristics of soils like water content, fine content, Atterberg limits and so on, are used to mode...

In this article, a new combined approach of a decision tree and clustering is presented to predict the transmission of genetic diseases. In this article, the performance of these algorithms is compared for more accurate prediction of disease transmission under the same condition and based on a series of measures like the positive predictive value, negative predictive value, accuracy, sensitivit...

Kaolin-SO3H as a new solid acid is prepared via reaction of kaolin and chlorosulfonic acid. This natural based catalyst is very inexpensive and easy available. Imidazoles are an important class of heterocycles being the core fragment of different natural products and biological systems such as anti-allergic, anti-inflammatory, analgesic, antifungal, antimycotic, antibiotic, antiulcerative, anti...

INTRODUCTION Rule induction tests such as the Wisconsin Card Sorting Test require executive control processes, but also the learning and memorization of simple stimulus-response rules. In this study, we examined the contribution of diminished learning and memorization of simple rules to complex rule induction test performance in patients with amnestic mild cognitive impairment (aMCI) or Alzheim...

 A simple, mild and practical procedure has been developed for the synthesis of symmetrical and unsymmetrical ethers by using DMSO, TBAI in the presence of K2CO3. We extended the utility of  Potassium carbonate as an efficient base for the preparation of ethers. A wide range of alkyl aryl and dialkyl ethers are synthesized from treatment of aliphatic alcohols and phenols with various alkyl hali...

The problem of estimating a random vector x from noisy linear measurements y = Ax + w with unknown parameters on the distributions of x and w, which must also be learned, arises in a wide range of statistical learning and linear inverse problems. We show that a computationally simple iterative message-passing algorithm can provably obtain asymptotically consistent estimates in a certain high-di...

We introduce a novel numerical method for a recently developed perspective Shape-from-Shading model. In order to discretise the corresponding partial differential equation (PDE), Prados et al. employed the dynamical programming principle yielding a Hamilton-Jacobi-Bellman equation. We reduce that model to its essential, namely to the underlying Hamilton-Jacobi equation. For this PDE, we propose...
