Previous studies have showed that phytoestrogen α-zearalanol (α-ZAL) could antagonize homocysteine (Hcy) induced endothelin-1 (ET-1) expression, oxidative stress and apoptosis in human umbilical vein endothelial cells in vitro, however, its effect on vascular function in vivo remains to be determined. This study was designed to investigate the effects of α-ZAL on vascular function in ovariectomized...
Although many methods for services composition can guarantee enforceability of services composition, they can not guarantee the rationality of services composition that can not determine whether an instance of services composition to achieve the desired target. Petri net-based model for grid services compositon is proposed for the grid application system in the paper. Then the reachability, boundedness,...
A dynamic application customization and service composition model based on max application template was proposed in this paper. We describe a kind of applicationpsilas businesses logic with max application template; in this template a customized application could be derivate according to userpsilas inputs. Based on the customized application the composed services can be processed to reach userpsilas...
As the importance of service's continuity for service-oriented computing (SOC) system and present QoS assurance mechanisms in SOC system did not take full account of the impact of the service components dynamics. In order to solve this problem credit model and credit function was put forward, CRD (credit record data) is used to quantize the SOC system's dynamic. A new QoS assurance mechanism which...
It is a big challenge to realize the dynamic selection and integration of the grid service component in the dynamic, cross-organizational grid environment. This paper introduces a dynamic-reconfigurable grid model (DRGM) with SOA. Reconfigurable idea is introduced to this model, and the implementation framework and method are proposed, so DRGM can support dynamic-reconfiguration at a lower level for...
Metal photo rework scheme which consists of NBA resist strip and ashing result to yield loss for 0.25 mum CMOS product. The failure pattern is cluster failures at the wafer center and mild failure at the wafer edge. Investigation showed that the frequency of heat treatment from 220degC to 250degC promotes the severity of sort failure. It indicates that there is insufficient thermal budget. Thus, the...
Energy performance contracting is an energy saving investment mode which using saving cost of energy to pay the cost of energy saving project. The general evaluating methods are unable to evaluate objectively the managerial elastic and strategic value existing in projects while evaluating the energy saving projects, thus the real value of projects can't be reflected. In the light of this problem,...
To achieve improvement of reliability and seamless transition between interconnected mode and islanding mode, the splitting strategy of intentional islanding of distributed generation (DG) is studied. This paper proposes rooted tree to model DG island separation according to the radial structure and service restoration process of distribution system. The level and directed properties of rooted tree...
The impact of distributed generation interconnection on reliability indices is analyzed in this paper. The reliability indices of sample network with re-closing, alternate feed, anti-islanding, intentional islanding are calculated respectively. Distributed generators often have a negative impact on reliability indices through re-closing failure, unintentional islanding and other improper strategies...
