A functional model of a simplified clarinet has been developed and implemented on a digital computer. The simplified clarinet consists of a standard clarinet mouthpiece and reed attached to a straight cylindrical tube. In the model, the tube and mouthpiece are represented by a lumped element approximation to a transmission line and the reed is represented as a nonuniform bar, clamped at one end...

This paper presents our work for participation in the 2012 CIPS-ParsEval shared task of Simplified Chinese parsing. We adopt a factored model to parse the Simplified Chinese. The factored model is one kind of combined structure between PCFG structure and dependency structure. It mainly uses an extremely effective A* parsing algorithm which enables to get a more optimal solution. Throughout this...

This work concerns the peristaltic flow of a Williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. The governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. The analytical results are computed with the help of regular perturbation and the numerical re...

The interaction between a fault arc and power system has a big influence on the successful reclosing of a faulted system and hence evaluation of this interaction is very important. This paper mainly focuses on a proposed technique of simplified arc model for evaluation of single phase reclosing scheme for extra high voltage transmission system. Both primary and secondary arcs behavior have been...

In this paper, we present a simplified higher-order Markov chain model for multiple categorical data sequences also called as simplified higher-order multivariate Markov chain model. The number of the parameters of the new model is only ) ) (( 2 sm s n O + which is less than ) (( 2 m ns O in the higher-order multivariate Markov chain model. Numerical experiments illustrate the benefits of our n...

Since the 1825 there is Gompertz mortality function for estimation of mortality data. All the attemts of finding apropriate mortality function lead to functions that are not easy to fit with the actual mortality data. The most recent reasearches (Azbel) offer simple function for fit mortality tables. Common characteristic of all these functions are difficulty of fiting data. We need to use nume...

expansion of apple growing to dry areas requires reliable approaches to select genotypes tolerant to water stress. we have simulated apple tree transpiration (ec) from different commercial orchards and compared it with actual transpiration (ea) derived from sap flow measurements. the modelling approach lies in rearranging a parameterized p–m equation and incorporating in it a stomatal conductan...

In Saudi Arabia, the Riyadh Sewage Treatment Plant (RSTP) uses the activated sludge technology as the secondary treatment process for sewage. Due to the complex nature of the process, a rather simplified, yet practical, steady state model that captures the most important features of the RSTP was developed. Actual operating and design conditions were obtained from RSTP data bank. The monthly ave...
