Web services provision is the process of assigning particular services to the constituent tasks of business processes. It describes a promising scenario where services are dynamically chosen and invoked in a business process according to their functional and non-functional capabilities. It also introduces many challenging problems and has received much(More)
As the world of Web services is dynamic and heterogeneous, a requester often needs to invoke an unfamiliar Web service at run time. However, current Web services technology pays little attention to this issue. In this paper, we propose a requester-based mediation framework for a requester to dynamically invoke Web services. The framework can increase the(More)
In this study, we investigate the direct electron-transfer reactivity of immobilized hemoglobin (Hb) on a polyurethane elastomer (PUE) film for biosensor designs. The PUE film synthesized by an additional polymerization possesses good biocompatibility, uniformity, and conformability and is ready for protein immobilization. Electrochemical and spectroscopic(More)
This feature article provides an overview of the preparation of functional nanofibers by combined electrospinning, controlled radical polymerization and 'Click Chemistry'. A combination of the powerful capability of controlled radical polymerization and 'Click Chemistry' for the synthesis of functional macromolecules and on surface modification as well as(More)
Monodisperse wurtzite CuIn(x)Ga(1-x)S(2) nanocrystals have been synthesized over the entire composition range using a facile solution-based method. Depending on the chemical composition and synthesis conditions, the morphology of the nanocrystals can be controlled in the form of bullet-like, rod-like, and tadpole-like shapes. The band gap of the(More)
Cu(2)FeSnS(4) (CFTS) nanocrystals with tunable crystal phase have been synthesized using a solution-based method. As-synthesized CFTS nanocrystals in the shape of oblate spheroid and triangular plate with band gaps of 1.54 ± 0.04 and 1.46 ± 0.03 eV, respectively, appear attractive as a low-cost substitute for thin film solar cells.
Web services can be described as local autonomous routines communicating with each other through message exchange. Hence a good understanding of the messages defined in each Web service is crucial to enabling automatic composition. This paper presents a semantic specification framework for analyzing the functional composability of autonomous Web services.(More)
Monodisperse nanocrystals of a new wurtzite phase of Cu(2)CoSnS(4) (CCTS) have been synthesized using a simple solution-based method. The wurtzite CCTS nanocrystals grow in the shape of nanorods with an average length of 32 ± 2.0 and width of 16 ± 1.5 nm. The more stable stannite phase of CCTS has also been synthesized by increasing the reaction temperature(More)
Web services technologies promise to create new business applications by composing existing services and to publish these applications as services for further composition. The business logic of applications is described by abstract processes consisting of tasks which specify the required functionality. Web services provision refers to assigning concrete Web(More)
Self-host thermally activated delayed fluorescence (TADF) materials have recently been identified as effective emitters for solution-processed nondoped organic light-emitting diodes (OLEDs). However, except for the carbazole unit, few novel dendrons have been developed to build self-host TADF emitters. This study reports two self-host blue materials,(More)
