Due to their numerous merits (such as high durability, diverse applicability, ready-availability, low-cost, reusability, and so on), the presumably inevitable use of plastics makes waste ubiquitously dispersed in our environment, especially oceans. The environmental damage posed, ecosystem, initiated need for recourse control these environmentally refractory pollutants. In this review, various ...

In this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of Exhaust Gas Recirculation (EGR) temperature on destruction of the fuel’s availability due to combustion processes in IDI diesel engine cylinder. To serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...

performing commitment by the third party   yusef mulaei (ph.d.) [1] amir najafi ghamat [2]   abstract by the personal intervention of the third party (other than the indebted) in performing a commitment, a new process will begin that is not out of the following three conditions. one is that the payment is “forcible” according to the legal ruling as is partially accepted by some internal regulat...

We consider power system expansion planning under uncertainty. In our approach, integer programming and stochastic programming provide a basic framework. We develop a multistage stochastic programming model in which some of the variables are restricted to integer values. By utilizing the special property of the problem, called block separable recourse, the problem is transformed into a two-stag...

Opportunities to make sequential decisions and adjust activities as a season progresses and more information becomes available characterise the farm management process. In this paper, we present a discrete stochastic two-stage utility efficient programming model of organic dairy farms, which includes risk aversion in the decision maker’s objective function as well as both embedded risk (stochas...

In this paper, we study a dynamic fleet management problem with uncertain demands and customer chosen service levels. We first show that the problem can be transformed into a dynamic network with partially dependent random arc capacities, and then develop a structural decomposition approach which decomposes the network recourse problem into a series of tree recourse problems (TRPs). As each TRP...

This paper reports on a recent development in Japan, funded by the Science and Technology Agency, for the creation and analysis of a very large database, including emotional speech, for the purpose of speech technology research. In order to capture spontaneous samples of naturally-occurring emotion without recourse to acting, a very large amount of conversational speech and daily spoken interac...

We solve a linear robust problem with mixed-integer first-stage variables and continuous second stage variables. We consider column wise uncertainty. We first focus on a problem with right hand-side uncertainty which satisfies a "full recourse property" and a specific definition of the uncertainty. We propose a solution based on a generation constraint algorithm. Then we give several generaliza...
