Although one is made to believe that a collaborative application that runs on a collection of heterogeneous mobile devices can be easily developed with the existing middleware technologies such as JXTA, BREW, compact .NET and J2ME, the reality is that they require too many ad-hoc techniques as well as cumbersome and time-consuming programming. Our System on(More)
Curcumin has very broad spectrum of biological activities; however, photodegradation, short half-life and low bioavailability have limited its clinical application. Curcumin-loaded solid lipid nanoparticles were studied to overcome these problems. The aim of this study was to optimize the best formulation on curcumin-loaded solid lipid nanoparticles.(More)
Most current reputation models fail to calculate peers’ reputation accurately when there is little transaction history between the peers. To this end, this paper presents a trust model combing reputation and credential which accepts inputs of both feedback and credential. The model is based on reputation-based trust model, and according to the(More)
The Photovoltaic–assisted Charging Station (PVCS) is regarded as one of the most promising charging facilities for future electric vehicle (EV) energy supplementation. In this paper, the operation mode and profitability of a commercialized PVCS are analyzed under the energy policy of China. In order to evaluate the long-term effectiveness of using the PVCS(More)
Graphene nanoplatelets were activated by a hydrothermal method using potassium hydroxide (KOH) as an activating agent. The activation process significantly increases the sample specific surface area from 2.4 m<sup>2</sup>/g to 48 m<sup>2</sup>/g. The activated graphene nanoplatelets (aGNP) were used as counter electrode (CE) in dye-sensitized solar cells(More)
