The buckling and postbuckling behaviors of a composite beam with single delamination are investigated. A three-dimensional finite element model using the commercial code ANSYS is employed for this purpose. The finite elements analyses have been performed using a linear buckling model based on the solution of the eigenvalues problem, and a non-linear one based on an incremental-iterative method....

In the broad literature of corporate risk management classic models of optimal hedging assume a one-period hedging decision, and therefore no financing need arises to maintain the hedge position. The multi-period models are usually based on the assumption of no liquidity constraints, and accordingly the eventual financing need can always be met from the market. As a consequence of the recent cr...

The Shapley value solution occupies a central place in fair division literature, specially in settings where a set of positions in a queue need to be shared between a set of agents using payments. But computing the Shapley value of an agent requires solving exponential number of optimization problems (marginal value problem). Moreover, it requires exact knowledge of valuation functions of agent...

as a continuous research for discovery of new cox-2 inhibitors, chemical synthesis, in vitro biological activity and molecular docking study of anew group of 1,4-dihydropyridine (dhp) derivatives were presented. novel synthesized compounds possessing a cox-2 so2me pharmacophore at the para position of c-4 phenyl ring, different hydrophobic groups (r1) at c-2 position and alkoxycarbonyl groups (...

We examine how participation and positioning in global value chains (GVC) affect wages. also whether this relationship is conditioned by a country’s development level labor market regulation. The results show that upstream specialization GVCs are associated with higher wages but only developed countries. In developing countries, while GVC wages, exerts downward pressure on For analysis focusing...

The construction of the Silk Road Economic Belt refers to enhancement trade and cultural communication among China countries along Road, aiming achieve mutually beneficial friendly development promote global economic growth. value chain represents a business organization that integrates commodity manufacturing, production, sales, after-sales services. holds significant position plays crucial ro...

Problem 1. this needs to be fleshed out We will use 3 arrays A, B, and C. A will represent that actual array and hold the stored items in their stored positions. Arrays B and C will act as “checks” for which entries of A are truly initialized. B will contain a list, built up sequentially from position 0, of all entries of A that have been filled. We use a “length” variable i to keep track of th...

[Purpose] The purpose of this study was to investigate the effect of forward head posture (FHP) on proprioception by determining the cervical position-reposition error. [Subjects and Methods] A sample population was divided into two groups in accordance with the craniovertebral angle: the FHP group and the control group. We measured the craniovertebral angle, which is defined as the angle betwe...

Various rehabilitation robots have been employed to recover the motor function of stroke patients. To improve the effect of rehabilitation, robots should promote patient participation and provide compliant assistance. This paper proposes an adaptive admittance control scheme (AACS) consisting of an admittance filter, inner position controller, and electromyography (EMG)-driven musculoskeletal m...
