We analyze two- and three-link planar snakelike locomotion and optimize the motion for efficiency. The locomoting system consists of two or three identical inextensible links connected via hinge joints, and the angles between the links are actuated as prescribed periodic functions of time. An essential feature of snake locomotion is frictional anisotropy: The forward, backward, and transverse c...

according to variety of accessible hydrological models, evaluateing the efficiency of models for different management objectives are essential. therefore, models with simple structure and using minimal input that can provide an acceptable result can serve as an effective tool to watershed managers. hence, the objective of this research is to evaluate the relative performances of the lumped conc...

Molecular Dynamics (MD) simulation and Density Functional Theory (DFT) methods have been used to evaluate the efficiency of four quinoline derivatives on corrosion inhibition in the aqueous phase. Some quantum chemical parameters such as hardness (η), electrophilicity (w), polarizability (a), energy of the highest occupied molecular orbital (EHOMO), energy of th...

to determine sugar beet water requirement and the effect of changing the quantity of applied water on some production components, a study was carried out in ekbatan agricultural research station of hamedān, iran in four years (1994-1997) during which optimum water requirement, root and sugar yield, water use efficiency on the basis of root yield, sugar percentage and water use efficiency on the...

Pareto dominance plays an important role in diverse application domains such as economics and e-commerce, and it is widely being used in multicriteria decision making. In these cases, objectives are usually contradictory and therefore it is not straightforward to provide a set of items that are the “best” according to the user’s preferences. Skyline queries have been extensively used to recomme...

In this paper we explore how specific aspects of mechanism design affect the efficiency of the market outcome. In particular, we are interested whether the availability of information about actions of other participants improves market efficiency. We consider a simple market of a homogeneous good populated by buyers and sellers. The valuations of the buyers and the costs of the sellers are give...

Although at the moment electronic payment via the Internet has no major impact on e-commerce sites, it will be a prerequisite for new business models, such as pay-per-view, and necessary for the success and cost efficiency of future e-commerce applications. Many payment protocols and frameworks for various business domains exist. However, they are incompatible which makes it hard for service de...

The systematic and proactive development of human resources is of major importance in organizations that rely heavily on the competencies of their employees when engaging in innovative endeavors. Human capital, however, is not only a resource required for conducting research, but also the eventual result of that research. When selecting a research portfolio, the decision-maker thus needs to tak...

Trust is known to be vital to business to customer (B2C) electronic commerce adoption. However, its role in customers’ blending of the online and traditional channels is largely unexplored. In this study, we progress beyond single channel adoption and investigate the interplay of trust and perceived efficiency on channel blending. Our conceptual framework models channel blending as a dynamic co...
