abstractbackground : in order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 mhz low level ultrasound based on °oh radicals generated by acoustic inertial cavitation in aqueous solution was monitor...
We present a large scale production scheduling problem where each order is unique and the processing time for an operation can be close to the size of a time period. Because modeling the problem as a multiprocessor owshop results in a computationally intractable formulation, we cast the problem in production planning terms and extract a production schedule from the solution. To solve our model,...
19. T. Oka, J. Mol. Spectrosc. 228, 635–639 (2004). 20. Here J denotes the rotational quantum number comprising end-over-end rotation R and internal rotation. 21. P. Bunker, B. Ostojić, S. Yurchenko, J. Mol. Struct. 695–696, 253 (2004). 22. Here we use the quantum number J instead of R, because the rotational motion in the state is not purely the end-over-end rotation. 23. M. Kolbuszewski, P. R...
this paper deals with continuous frames and continuous riesz bases. we introduce continuous riesz bases and give some equivalent conditions for a continuous frame to be a continuous riesz basis. it is certainly possible for a continuous frame to have only one dual. such a continuous frame is called a riesz-type frame [13]. we show that a continuous frame is riesz-type if and only if it is a con...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Extensive research has been devoted to economic production quantity (EPQ) problem. However, little atten-tion has been paid to problems where depreciation cost and process quality cost must be considered, simulta-neously. In this paper, we consider the economic production quantity model of minimizing the annual total cost subject to depreciation cost and process quality cost, where depreciation...
