abstract one of the basic assumptions in hub covering problems is considering the covering radius as an exogenous parameter which cannot be controlled by the decision maker. practically and in many real world cases with a negligible increase in costs, to increase the covering radii, it is possible to save the costs of establishing additional hub nodes. change in problem parameters during the pl...

We demonstrate high dynamic range (HDR) imaging with the Plenoptic 2.0 camera. Multiple exposure capture is achieved with a single shot using microimages created by microlens array that has an interleaved set of different apertures. © 2009 Optical Society of America OCIS codes: (040.1490) Cameras, 110.5200 Photography.

in recent years, researchers have become interested in examining the effect of pettlep imagery on motor performance and how pettlep imagery can improve the performance. the aim of this study was to compare the effect of pettlep imagery and balance practice on dynamic balance in the elderly. participants were 42 male elderly in arak city. they were divided into 4 groups based on the scores of dy...

insulin-like growth factor (igf-1) is an anti-apoptosis factor in multiple cell types associated with various cancers. computational methods allow investigating the systems between 50–100 atoms in the frame of quantum mechanics and up to 50,000 atoms with molecular dynamics. since there are specific interactions between the residues, the solvent could play an important role in the stability of ...

Abstract Electrode materials for lithium-ion batteries (LIBs) typically show spherical particle shapes. For cathode materials, the shape is obtained through synthesis method. graphite, by far most popular anode material LIBs, particles are a spheroidization process. The yield of that process quite low and limited to about 50%, leaving substantial amounts by-products. Using such lower quality by...

this paper studies the dynamic behavior of price elasticity and its effects on the overall profit. although price elasticity has a significant effect on sales, its dynamics have not been examined so far in pricing models. in this paper, a simple pricing model is suggested in which, price elasticity is considered dynamic. the suggested pricing model is concerned with a monopolist that its object...

Long-term hypothermic storage of animal blood can lead to the loss its quality and cause complications in recipient animals after transfusion, so search for new methods increasing preservation erythrocytes continues. The article presents data ozonation effect on rate ovine human during with Alsever’s solution mannitol medium. Hemolysis, osmotic fragility distribution density by sphericity index...

Mg alloys have poor formability due to their hexagonal tightly packed (HCP) crystal structure, low active shear system at room temperature, and anisotropic behavior in polycrystalline structure. While this situation hindered the development commercialization of some extent past, today developments machining, liquid forming semi-solid technology removed these obstacles. Semi-solid has been subje...

Approaches to the design of recycling-tolerant Al-Zn-Mg alloys were formulated be achieved via combined Ca, Fe, and Si, appropriate solidification conditions heat treatment. A CalPhaD calculation experimental study employed for analysis Al-8%Zn-3%Mg alloy doped with 1–2%Ca, 0.5%Fe, 0.5%Si. The Al-8%Zn-3%Mg-1%Ca-0.5%Fe-0.5%Si (AlZnMg1CaFeSi) was preliminarily found promising since it showed a hi...
