improving mechanical properties of composites based on strength-to-weight ratio has been gained much attention in various applications. having the most resistant and at the same time the lightest and the most economical structure is believed as an aim in these applications. these three factors are usually opposed to each other. so, applying optimization algorithms for improving mechanical prope...
The conclusions reached by a diverse group of scientists who attended an intense 2-day workshop on hybrid organic-inorganic perovskites are presented, including their thoughts on the most burning fundamental and practical questions regarding this unique class of materials, and their suggestions on various approaches to resolve these issues.
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
Hybrid sticky price model is one of the main models, used to analyze the Persistencyand inertia in inflation. In recent years, Mankiw and Reis (2002),s sticky information model, has also been considered by many economic analysts. So, in present paper, we try to investigate and compare these models by using a Dynamic Stochastic General Equilibrium (DSGE) framework, based on new Keynesian s...
Hybrid (discrete/continuous) systems are systems that exhibit both discrete state and continuous state dynamics. In addition, these two aspects of system behavior interact to such a significant extent that they cannot be decoupled and must be analyzed simultaneously. We consider the modeling, simulation and sensitivity analysis of hybrid systems, with particular emphasis on the interactions bet...
Abstract. We consider a non linear ordinary differential equation and want to control its behavior so that it reaches a target by minimizing a cost function. Our approach is to use hybrid systems to solve this problem: the complex dynamic is replaced by piecewise affine approximations which allow an analytical resolution. The sequence of affine models then forms a sequence of states of a hybrid...
Modeling gene regulatory network is a difficult task. Experiments often fail at giving enough information for parameterizing existing models. We propose herein a dedicated hybrid modeling. To overcome the lack of quantitative information, our modeling focuses on (i) the biological compound product signs and (ii) the temporal properties associated with the biological effects of the interactions....
Keywords: Workforce management Hybrid heuristic Personnel scheduling Matheuristic Retail a b s t r a c t This work proposes a scheduling problem for the workforce management in a chain of supermarkets operating in Italy. We focus on determining the ideal mix of full-time and part-time workers which are needed every week to guarantee a satisfactory service level during the check-out operations. ...
