A method for compression of large graphs and matrices to a block structure is proposed. Szemerédi’s regularity lemma is used as a generic motivation of the significance of stochastic block models. Another ingredient of the method is Rissanen’s minimum description length principle (MDL). We propose practical algorithms and provide theoretical results on the accuracy and consistency of the method.

A modular web-based approach for simulation-based optimization of multi-physics systems is described. The basic principle is the flexible coupling of an optimization toolbox with a variety of simulators via LAN or Internet. The structure and basic solutions for tool integration, communication, and user interaction are discussed. For a practical optimization task the usability of the approach is...

Two principally different statements of the problem of stable numerical differentiation are considered. It is analyzed when it is possible in principle to get a stable approximation to the derivative f ′ given noisy data fδ. Computational aspects of the problem are discussed and illustrated by examples. These examples show the practical value of the new understanding of the problem of stable di...

The paper deals with a modification of a Sparse distributed memory that uses some features of a Restricted coulomb energy classifier. The basic principle, topology, data storing and retrieving and one practical application of this net, including special input and output data encodings, are described.

Through an analysis of the unique features of the Internet as an environment for cyberdating, this work examines the issues of (mis)information and (dis)trust in romantic endeavors and encounters in the virtual world. With a critical application of Grice’s Cooperative Principle to a reported case of fraud in cyberdating, this paper offers practical suggestions for cyberdaters.

The property of monotonicity, th criterion of (first-degree) income dominance and the Pareto principle appear frequently in the literature on the axiomatic approach to the welfare economics of income distribution. Sometimes these are regarded as almost interchangeable for practical purposes. However, as we shall show, this interchangeability arises because of other important assumptions that ar...

Paper presents simple sixport principle and its frequency bandwidth. The novel multisixport approach is presented with its possibilities, typical parameters and frequency bandwidth. Practical implementation is shown with its measurement parameters and calibration. The bandwidth circa 1:100 is obtained. Keywords— microwave measurement, sixport, VNA, wideband.

kant’s ethical theory is one the most important theories in philosophy of ethics, which has always attracted the attention of the commentators and critics. although it has many positive points, there are some objections to this theory just as to any other human theory. in this article, it is attempted to point out the critiques that seem to have been leveled against kant’s ethics. some of these...

In replying to my argument that the speed furnished by parallel processing is highly relevant to the understanding of intelligence and mind, Krellenstein says that “the serial simulation of parallel processes and the portability of software are computational principles and everyday empirical realities.” While it is true that in principle parallel processes can be simulated on serial machines, t...
