A new design approach of a digital delta-sigma modulator with small output fluctuation is proposed. The digital delta-sigma modulators are used in the digital-analog converters, the fractional-N phase lock loop, etc. and its output fluctuation is one of the important performances although a higher order modulator often produces large fluctuations. In this work, the noise shaping filter of the m...

Super Flexible Messaging (SFM) provides a powerful and elegant message passing abstraction for transferring arbitrary data between remote processes. SFM achieves the simplicity of stream-oriented mechanisms and the ability to transfer structured data as found in high-level remote object invocation systems. Leveraging off of dynamic typing and named arguments in functions, SFM offers a simple sy...

Design is a multi-objective decision-making process considering manufacturing, cost, aesthetics, usability among many other product attributes. The set of optimal solutions, the Pareto set, indicates the tradeoffs between objectives. Decision-makers generally select their own optima from the Pareto set based on personal preferences or other judgements. However, uncertainties from manufacturing ...

Several radial basis function based methods contain a free shape parameter which has  a crucial role in the accuracy of the methods. Performance evaluation of this parameter in different  functions with various data has always been a topic of study. In the present paper, we consider studying the methods which determine an optimal value for the shape parameter in interpolations of radial basis  ...

Oblivious transfer (OT) is a cryptographic primitive of central importance, in particular in twoand multi-party computation. There exist various protocols for different variants of OT, but any such realization from scratch can be broken in principle by at least one of the two involved parties if she has sufficient computing power—and the same even holds when the parties are connected by a quant...

in this article, we propose an adaptive grid based on mesh equidistribution principle for two-parameter convection-diffusion boundary value problems with continuous and discontinuous data. a numerical algorithm based on an upwind finite difference operator and an appropriate adaptive grid is constructed. truncation errors are derived for both continuous and discontinuous problems. parameter uni...

In this study, the performance of an irreversible regenerative Brayton cycle is sought through power maximizations using finite-time thermodynamic concept in finite-size components. Optimizations are performed using a genetic algorithm. In order to take into account the finite-time and finite-size concepts in the current problem, a dimensionless mass-flow rate parameter is used to deploy ti...
