This paper studies the ε-approximate range emptiness problem, where the task is to represent a set S of n points from {0, . . . , U − 1} and answer emptiness queries of the form “[a; b] ∩ S 6= ∅ ?” with a probability of false positives allowed. This generalizes the functionality of Bloom filters from single point queries to any interval length L. Setting the false positive rate to ε/L and perfo...

  All desalination methods which are currently used have limitations. A newly designed instrument by Zare A.M. was tested and compared with currently used method in Razi Vaccine and Serum Research Institute(RVSRI). Samples of anti snake venom for desalination was provided by department of anti-serum, RVSRI. Parameters included in this study were time and water consumption during desalination pr...

Early this year the author presented at the convention of the Optical Society of America a paper giving a brief review of the methods which had previously been used in measuring reflection factors, and describing a new type of absolute reflectometer. The complete description of that instrument, with the derivation of the theory, is now available in a scientific paper of this Biureau.* The instr...

A low-voltage low-power discrete time sigma delta modulator for biomedical signal acquisition designed and implemented in 0.18-μm CMOS process is presented in this paper. This sigma delta modulator is designed using cascaded 3rd-order feedback form of integrator with the over sampling ratio (OSR) of 32. The experimental prototype chip achieves 55dB and 60dB dynamic range for 200Hz and 500Hz sig...

A two-stage modelling schema to be used together with arithmetic coding is proposed. Main motivation of the work has been the relatively slow operation of arithmetic coding. The new modelling schema reduces the use of arithmetic coding by applying to large white regions global modelling which consumes less time. This composite method works well and with a set of test images it took only ca. 41%...

This paper explores the design and analysis of Static Random Access Memories (SRAMs) which focusses on optimizing delay and power. CMOS SRAM cell consumes very less power and have less read and write time. Higher cell ratios can decrease the read and write time and improve stability. PMOS transistor with less width reduces the power consumption. In this paper, 6T SRAM cell is implemented with r...

Dynamic lot sizing problem is one of the significant problem in industrial units and it has been considered by  many researchers. Considering the quantity discount in  purchasing cost is one of the important and practical assumptions in the field of inventory control models and it has been less focused in terms of stochastic version of dynamic lot sizing problem. In  this paper, stochastic dyn...

The paper extends a dynamic version of the classical von NeumannMorgenstern setting to incorporate a degree of confidence in or subjectivity of probabilistic beliefs. It provides a simple axiomatic characterization of a new preference representation that addresses ambiguity from a simple perspective, employing only basic tools from risk analysis. Conceptually, the paper renders the concept of s...

So it is time. I had rather hoped it would never come but, well now you have it, our journal has soon to start charging for publication. You see, for the past almost two years our generous publisher – OUP-has absorbed the costs of an incredible scientific output that has placed JHPS in the very forefront of publishing in the field of hip preservation surgery. Forefront? Let me show you. I did a...

Energy efficiency of software is an increasingly important topic. To achieve energy efficiency, a system should automatically optimize itself to provide the best possible utility to the user for the least possible cost in terms of energy consumption. To reach this goal, the system has to continuously decide whether and how to adapt itself, which takes time and consumes energy by itself. During ...
