I this paper, we investigate the equilibrium behavior of decentralized supply chains with competing retailers under demand uncertainty. We also design contractual arrangements between the parties that allow the decentralized chain to perform as well as a centralized one. We address these questions in the context of two-echelon supply chains with a single supplier servicing a network of (competi...

H-rotor Vertical Axis Wind Turbine (VAWT) is one of the most efficient energy suppliers which have been investigated in many recent types of research. The aim of this work is to study the aerodynamic performance of a doubled-row H-Darrieus VAWT. First, an ordinary three-bladed VAWT with NACA4415 profile is simulated by means of 3D computational fluid dynamics (CFD) and results are compared to a...

This paper describes the drone-based visual assist system for teleoperated construction robot. The drone hovers at side or front of robot to capture images work area. operator switches drone's hover position by operating a switch. If many positions are set, can determine in detail, but operational burden may increase. proposed several combinations and compared them experimentally.

The Front Cover shows some of the key features and benefits employing BIANs as redox non-innocent ligands including a chemist with two flasks helping to illustrate just how “simple” BIAN synthesis can be. ability use electron reservoirs capable storing releasing electrons on demand in catalysis has helped unleash an onslaught 1st-row metal catalysts onto chemical community. Armed ligands, chemi...

Increasing level of carbon dioxide CO2 due to industrial activity is primarily cause of global warming. Planting Artoplex lentiformis can help to reduce atmospheric CO2 buildup partly replacing use of fuels and by carbon storage. The objective of this study was to determine the effects of row spacing on carbon storage. A split- plot design with three replications included three row spacing (2×2...

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

background: economic burden due to premature mortalities is significant both on health system and on the society as a whole. this study aimed to determine the productivity costs and years of potential life lost associated with five leading causes of death in iran from 2006 to 2010.   methods: data on mortality by sex and age-groups due to five main leading causes of death   (myocardial infarcti...

the present study is an attempt to find out cultural exophoric references in four common english textbooks, namely touch stone, american file, top notch, and total english series used at iranian english language institutes and to compare the frequency of occurrence of such references in these coursebooks. in order to compare cultural exophoric references used in these coursebooks, the researche...
