This paper relates to vibration control using passive electrical shunt circuits. However, the vibration shunt control efficiency relies on the optimization of the vibration energy transfer between a structure and a Lead-Zirconate-Titanate (PZT) piezoelectric ceramic material. The problem is further complicated by the material composition of the substrate or host material the PZT is coupled to. ...

As services in an SOA can be composed of lower level services, there will exist dependencies between services. Changing services can impact other services in the SOA and a lot of manual service management tasks are required. Our goal is to create a method for analyzing change effects of service adaptations within an SOA. More specific, we study: which services are affected when a certain servic...

We present identity-based identification (resp. encryption, signature, blind signature, ring signature) from composite degree residuosity (CDR). Constructions of identifications and signatures motivated by several existing CDR-based bandwidth-efficient encryption schemes are presented. Their securities are proven equivalent to famous hard problems, in the random oracle model. Motivated by Cocks...

This paper describes the simulation-based synthesis of optimum dispatching rules for the wafer test area of a semiconductor production plant. The target of the optimisation task is the minimum average lead time under the constraint of maintaining on-time delivery. Dispatching is a very fast and robust technique for sequence-planning even when cycle times are not perfectly controlled. A broad ra...

Web Service Choreography Description Language is a main-stream standard for the description of peer-to-peer collaborations for the participants for service composition. To predict the performance of composite service processes gives the way to tell whether the process meet the non-functional requirements, and to choose the process with better performance from those with identical function. Unfo...

The electrical properties of solution-processed composite thin films consisting of functionalized graphene sheets (FGS) as the filler and polystyrene (PS) as the host material are described. We demonstrate that transistors from graphene-based composite thin films exhibit ambipolar field effect characteristics, suggesting transport via percolation among FGS in the insulating PS matrix. Device ch...

The paper describes a program currently underway at Composite Technology Development, Inc. to dramatically improve the design and capabilities of lightweight linerless composite tanks. The program integrates material development and characterization, micromechanics-based analyses of composite materials and structural design and fabrication of prototype tanks. This integrated systematic approach...

BACKGROUND Silorane-based composites and their specific self-etch adhesive were introduced to conquest the polymerization shrinkage of methacrylate-based composites. It has been shown that additional etching of enamel and dentin can improve the bond strength of self-etch methacrylate-based adhesives but this claim is not apparent about silorane-based adhesives. Our objective was to compare the ...

Silver nanoparticles were synthesised by a chemical reduction process in order to produce an aqueous colloidal dispersion. The resulting colloids were then characterised by a combination of UV-Vis spectroscopy, dynamic light scattering, X-ray diffraction and transmission electron microscopy and the nanoparticles were found to have an average diameter of 20-22 nm. The Ag/polymer nanocomposites w...
