In dynamic analysis, frequency domain analysis can be used if the entire structure is linear. However, time history analysis is generally used if non-linear elements are present. Rayleigh damping has been widely used in time history response analysis. Many articles have reported the problems associated with this damping and suggested remedies. A basic problem is that the frequency area across w...

The competition between reptation and Rouse Dynamics is incorporated in the Rubinstein-Duke model for polymer motion by extending it with sideways motions, which cross barriers and create or annihilate hernias. Using the DensityMatrix Renormalization-Group Method as solver of the Master Equation, the renewal time and the diffusion coefficient are calculated as function of the length of the chai...

product innovation success has very much to do with the development of models ormetaphors that are able to guide actors. one can observe two traditions in thisregard: rational and non-rational models. apparently in the former the model, suchas “development funnel”, is regarded as a mechanism and rigid applicable, picturinginnovation as an orderly, goal-oriented, value-neutral, and systematic pr...

Background. In recent decades, information technology has become a vital component of various aspects of our lives. The use of information technology in different domains has made the analysis of the level of its acceptance/rejection a significant factor in organizations. Objectives. The aim of this study was to illustrate the application of the extended technology acceptance model in sports o...

In portfolio theory, it is well-known that the distributions of stock returns often have non-Gaussian characteristics. Therefore, we need non-symmetric distributions for modeling and accurate analysis of actuarial data. For this purpose and optimal portfolio selection, we use the Tail Mean-Variance (TMV) model, which focuses on the rare risks but high losses and usually happens in the tail of r...

This is Part 6 of a tutorial series on Term Vector Theory. The Extended Boolean Model is discussed. By varying the model p-norm parameter, from p = 1 to p = , we can vary its ranking behavior from that of a vector spacelike to that of a strict Boolean-like.

A major obstacle in applying finite-state model checking t o the verification of large systems is the combinatorial explosion of the state space arising when m a n y loosely coupled parallel processes are considered. T h e problem also known as the state-explosion problem has been attacked from various sides. This paper presents a new approach based o n partial model checking: Parts of the conc...

General Gaming is a field of research on systems that can manage various game descriptions and play them effectively. These systems, unlike specialized ones, must deal with various kinds of games and cannot rely on any kind of game algorithms designed upstream, such as DEEPER BLUE ones. This field is currently mainly restricted to complete-information board games. Given the lack of more various...

among the therapeutic options for achalasia are pneumatic dilatation (pd), an appropriate long-term therapy, and botulinum toxin injection (bt) that is a relatively short-term therapy. this study aimed to compare therapeutic effect of repetitive pneumatic dilation with a combined method (botulinum toxin injection and pneumatic dilation) in a group of achalasia patients who are low responder to ...
