Isolations of sylvatic dengue-2 virus from mosquitoes, humans and non-human primates in Senegal show synchronized multi-annual dynamics over the past 50 years. Host demography has been shown to directly affect the period between epidemics in other pathogen systems, therefore, one might expect unsynchronized multi-annual cycles occurring in hosts with dramatically different birth rates and life ...

in this paper, a new alternative method for order reduction of high order systems is presented based on optimization of multi objective fitness function by using harmony search algorithm. at first, step response of full order system is obtained as a vector, then, a suitable fixed structure considered for model order reduction which order of original system is bigger than fixed structure model. ...

In this paper, we examine the parametrization of all stabilizing multiperiod repetitive controllers with the specified frequency characteristics. The parametrization of all stabilizing multi-period repetitive controllers, those are used to improve the disturbance attenuation characteristics of the repetitive controller, for non-minimum phase systems was solved by Yamada et al. However, when we ...

The accelerated penetration rate of renewable energy sources (RES) brings environmental benefits at the expense increasing operation cost and undermining satisfaction N-1 security criterion in transmission systems. To address latter issue, this paper envisions control RES dominated power systems through stochastic multi-period AC constrained optimal flow (SCOPF). extends state-of-the-art, i.e. ...

Decision-makers in organizations and other hierarchical systems interact within and across multiple organizational levels and take interdependent actions over time. The challenge is to identify incentive mechanisms that align agents’ interests and to provide these agents with guidance for their decision processes. To this end, we developed a multiscale decision-making model that combines game t...

Process integration aims at optimizing industrial processes by identifying the heat recovery potential and the optimal integration of energy conversion systems. Most industrial processes especially in the food industry are non-continuous problems (batch problems) that are more difficult to tackle with process integration techniques. Process integration of multi-period problems can become comple...

We consider a basic model of multi-period trading, which can be used to evaluate the performance of a trading strategy. We describe a framework for single-period optimization, where the trades in each period are found by solving a convex optimization problem that trades off expected return, risk, transaction cost and holding cost such as the borrowing cost for shorting assets. We then describe ...

This work deals with a multi-period capacitated location problem inspired by telecommunication access network planning problems, where demands and costs vary from one period to another. On each concentrator site, several capacitated concentrators can be installed at each period. Similarly, several capacitated modules can be installed at each period between each terminal and concentrator sites. ...
