آلتراسوند یکی از روش های تصویربرداری است که هیج ضرری برای بدن ندارد، بنابرین نسبت به سایر دستگاه های پزشکی از محبوبیت و کاربرد بیشتری برخوردار است. طراحی بورد front-end یکی از چالشهای بزرگ در طراحی دستگاه سونوگرافی است که در آن سیگنالهای مدوله شده از بدن با دامنه بسیار کم باز می گردند که می توانند در رنج فرکانسی 2 تا 12 مگاهرتز کار کنند. تکنولوژی روز سعی در کوچک کردن مدارهای الکترونیکی و کمینه ...
In the nineties, A.G. Spera introduced a construction principle for divisible designs. Using this method, we get series of divisible designs from finite Laguerre geometries. We show a close connection between some of these divisible designs and divisible designs whose construction was based on a conic in a plane of a 3-dimensional projective space.
A divisible design graph is a graph whose adjacency matrix is the incidence matrix of a divisible design. Divisible design graphs are a natural generalization of (v, k, λ)-graphs, and like (v, k, λ)-graphs they make a link between combinatorial design theory and algebraic graph theory. The study of divisible design graphs benefits from, and contributes to, both parts. Using information of the e...
Example 1 Lets consider the integers from 1 to 10,000. The properties are defined as follows: E1 = property that an integer is divisible by 4 E2 = property that an integer is divisible by 5 E3 = property that an integer is divisible by 6 The probabilities of individual divisability are easily computed: Pr [E1] = probability the number is divisible by 4 = 1=4 Pr [E2] = probability the number is ...
Recently, some divisible electronic cash (e-cash) systems have been proposed. However, in existing divisible e-cash systems, efficiency or unlinkability is not sufficiently accomplished. In the existing efficient divisible cash systems, all protocols are conducted in the order of the polynomial of logN where N is the divisibility precision (i.e., (the total coin amount)/ (minimum divisible unit...
Divisible design digraphs are constructed from skew balanced generalized weighing matrices and Hadamard matrices. Commutative non-commutative association schemes shown to be attached the divisible digraphs.
The algebraic structure of divisible abelian semigroups has been studied in [9] and [l]. Some results on the topological and algebraic structure of compact uniquely divisible abelian semigroups have been obtained in [4] and [5]. A statement of equivalent conditions for a compact abelian semigroup to be divisible is presented in the present paper. Some of the results in [4] are extended to subun...
We introduce the concept of a (p; d)-divisible problem, where p reeects the number of processors and d the number of communication phases of a parallel algorithm solving the problem. We call problems that are recursively (n ; O(1))-divisible in a work-optimal way with 0 < < 1 ideally divisible and give motivation drawn from parallel computing for the relevance of that concept. We show that seve...
