• New OP variant with service time dependent profits and travel times. Mathematical formulation possible applications of this problem. Metaheuristic solution approach composed specific local moves. Benchmark instances known optimal solutions to verify the approach. Real data instance evaluate proposed model method. This paper addresses orienteering problem windows (TDOPTW-STP). In TDOPTW-STP, e...

reduced differental transform method (rdtm), which isone of the useful and effective numerical method, is applied to solve nonlinear time-dependent foam drainage equation (fde) with different initial conditions. we compare our method with the famous adomian decomposition and laplace decomposition methods. the obtained resultsdemonstrated that rdtm is a powerful tool for solving nonlinear par...

patients and methods this retrospective cohort study included 405 renal transplant patients from kerman university of medical sciences hospital, kerman, iran from 2004 to 2010. kaplan-meier method was used to estimate survival rates of patients, and time-dependent cox regression was used to examine the effect of allograft failure on patient survival. results during 4.06 years (median) of follow...

This paper considers a time dependent(the travel time is not constant throughout the day) pollution routing problem (TDPRP), which aids the decision makers in minimizing travel time, toll cost and emitted pollution cost.  In complexity of urban areas most of the time one point is accessible from another with more than one edge. In contrast to previous TDPRP models, which are designed with only ...

Pistachio butter (semi solid paste), which is made from roasted pistachio kernels, is an appropriate alternative to work on because of its high nutritional and economical values. In this study, timedependent flow properties of pistachio butter were determined at two different temperatures (25˚C and 45˚C) for five different formulations (with different levels of emulsifying agents). Forward a...

in this paper mathematical structure of time-dependent lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent lagrangian systems are considered. starting point is time-independent lagrangian systems ,then we extend mathematical concepts of these systems such as equivalent lagrangian systems to the...
