in this study, we present a mrcpsp/max (multi-mode resource-constrained project scheduling problem with minimum and maximum time lags) model with minimization tardiness costs and maximization earliness rewards of activities as objective. the proposed model is nearby to real-world problems and has wide applications in various projects. this problem is not available in the literature exactly and ...

there are many indices for measuring property rights (pr) security. they may be classified into two groups: subjective proxies and objective proxies. most of the proxies are subjective. one contribution of this paper is introducing a new approach for measuring government expenditures devoted to pr protection. calculating physical capital within the introduced new approach is another contributio...

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

Many of the properties of the well-known Kohonen map algorithm are not easily derivable from its discrete formulation. For instance, the “projection” implemented by the map from a high dimensional input space to a lower dimensional map space must be properly regarded as a projection from a smooth manifold to a lattice and, in this framework, some of its property are not easily identified. This ...

The flawless functioning of the protein is essentially related to its three-dimensional structure. Therefore,predicting structure from amino acid sequence a fundamental problem that draws researchers' attentionin many areas. prediction (PSP) can be formulated as combinatorial optimization based on simplified lattice models such hydrophobic-polar model. In this paper, we propose new hybridalgori...
