در این پایان نامه، با بهره گیری از ویژگی های ترانزیستورset، ساختار جدیدی برای مبدل آنالوگ به دیجیتال مبتنی بر ساختار folding ارائه می شود و با مقایسه بین ساختار پیشنهادی و ساختارهای پیشین مشاهده می شود که فرکانس نمونه برداری بهبود یافته و از طرف دیگر تلفات توانی و تعداد اجزا به کار گرفته شده در ساختار کاهش چشم گیری داشته است. البته با به کار گیری مدار ترکیبی set/cmos در ساختار پیشنهادی شاهد بهت...
In this paper, a new distribution of the three-parameter lifetime model called the Marshall-Olkin Gompertz is proposed on the basis of the Gompertz distribution. It is a generalization of the Gompertz distribution having decreasing failure rate and can also be increasing and bathtub-shaped depending on its parameters. The probability density function, cumulative distribution function,...
UNLABELLED Cage-shaped protein, with its special structure, may have potential applications in biomedicine and nanotechnology. We developed a program CSPro (Cage-Shaped Protein) for efficient identification of cage-shaped proteins based on quaternary structure. CSPro is capable of revealing the corresponding cage-shaped feature more clearly and quickly than traditional visualization tools. Usin...
A major consideration in the design of the accelerator structures in the injector linacs of the JLC/NLC[1] is to keep the wakefield effects within tolerances for both the nominal (2.8 ns) and alternate (1.4 ns) bunch spacings. One important multi-bunch wakefield effect is beam break-up (BBU), where a jitter in injection conditions of a bunch train is amplified in the linac; another is static em...
This paper proposes an innovative band selection (BS) method called prototype space band selection (PSBS) based only on class spectra. The main novelty of the proposed BS lies in band representation in a new space called prototype space, where bands are characterized in terms of class reflectivity to pose reflection properties of classes to bands. Having clustered the bands by K-means in the pr...
A bizarre Cretaceous theropod dinosaur from Patagonia and the evolution of Gondwanan dromaeosaurids.
Fossils of a predatory dinosaur provide novel information about the evolution of unenlagiines, a poorly known group of dromaeosaurid theropods from Gondwana. The new dinosaur is the largest dromaeosaurid yet discovered in the Southern Hemisphere and depicts bizarre cranial and postcranial features. Its long and low snout bears numerous, small-sized conical teeth, a condition resembling spinosau...
Plunkett & Marchman (1993) showed that a neural network trained on an incrementally expanded training set was able to master the past tense and show the U-shaped learning pattern characteristic of children. In Jackson, Constandse & Cottrell (1996) we argued that Plunkett & Marchman’s restriction of the training set was unrealistic and proposed a model of selective attention that enabled our net...
The fossil record is the only source of information on the long-term dynamics of species assemblages. Here we assess the degree of ecological stability of the epifaunal pterioid bivalve assemblage (EPBA), which is part of the Middle Devonian Hamilton fauna of New York--the type example of the pattern of coordinated stasis, in which long intervals of faunal persistence are terminated by turnover...
Laparoscopic Adjustable Gastric Banding (LAGB) was done for the first time in Belgium in 1993. Gastric torsion after band slippage is extremely rare. Literature review of gastric banding and complications in pregnancy did not reveal any case of gastric torsion. Hence, we report this rare case of gastric torsion in a pregnant lady following gastric banding.
