About at the break of sixties and seventies of this century the first functional and publicly used information system developed from originally experimental and non commercial applications of computer technology in storing and retrieval of document records. At the beginning these were mostly parallel editions of bibliographies in both printed and magnetic format. Thus developed on one hand data...

In the economical caching problem, an online algorithm is given a sequence of prices for a certain commodity. The algorithm has to manage a buffer of fixed capacity over time. We assume that time proceeds in discrete steps. In step i, the commodity is available at price ci ∈ [α, β], where β > α ≥ 0 and ci ∈ N. One unit of the commodity is consumed per step. The algorithm can buy this unit at th...

This article proposes two conformal Solow models (with and without migration), accompanied by simulations for six Organisation Economic Co-operation Development economies. The are proposed employing suitable Inada conditions on the Cobb–Douglas function making use of truncated M-derivative Mittag–Leffler function. In exact solutions derived in this manuscript, new parameters play an important r...

health lifestyle as a multi causal phenomenon, multidimensional and multiresonalcontributes to behavioral patterns that deals with health minatory problems of people; and in this way, can guarantee their health. by cockerham vision, health lifestyle realizes with choice concept, but a choice that occurs in social structure that itself affects by different factor. in this paper we try to find th...

Since the financial crisis burst out in 2008, the capital structure of banking has become the important question which the theorists pay close attention to, so this article focused on China Listed Commercial Bank’s capital structure. Based on a summary on the capital structure theory, this article analyzed the definition and characteristics of the banking capital structure. Besides, this articl...

A successful cogeneration system design project needs an estimation of the economical parameters of the project, including capital investment, costs of fuel, expenses in maintenance and operating, and the proper cost for the products. This study describes the economic consideration of the benchmark cogeneration systems, called CGAM system located in the United States. To evaluate the profitabil...

As a service to the bridge design profession, Bethlehem Steel has conducted hundreds of studies of steel plate girder bridges using its Preliminary Bridge Girder Optimization Program. The program is unique because it optimizes plate girder designs on the basis of least cost, not least weight. An evaluation of many study results leads to a number of guidelines which are offered in this paper. Wh...

This thesis proposes architectures and algorithms for digital acquisition of parametric signals. It furthermore provides bounds for the performance of these systems in the presence of noise. Our simple acquisition circuitry and low sampling rate enable accurate parameter estimation to be achieved economically. In present practice, sampling and estimation are not integrated: the sampling device ...
