The purpose of this note is to informally specify a case study in coordination describing a real world problem. The case study concerns peer review and evaluation of submissions to scientific conferences exploiting the Internet as the infrastructure for communication and cooperation. More precisely, we intend to specify a system for supporting all the activities which typically have to be perfo...

This paper proposes a new approach to operating system support for fault tolerance. We argue that in order to meet diverse application fault-tolerance requirements, the operating system should allow users to extend its functionality to support application-specific fault-tolerance protocols. We show that this kind of customisability can be achieved by explicitly decomposing the operating system ...

In this paper, we describe the Triana problem-solving environment and outline how a scientist might use it to modularize their applications into a set of cooperating components. We show that using this approach, applications can be distributed onto the Grid in a flexible and intuitive way using any of the distribution policies and mechanisms available within Triana. This is illustrated through ...

This paper proposes a purpose-based framework for supporting privacy preserving access control policies and mechanisms. The mechanism enforces access policy to data containing personally identifiable information. The key component of the framework is purpose involved access control models (PAC) that provide full support for expressing highly complex privacy-related policies, taking into account...

Aiming at harvesting ambient mechanical energy for self-powered systems, triboelectric nanogenerators (TENGs) have been recently developed as a highly efficient, cost-effective and robust approach to generate electricity from mechanical movements and vibrations on the basis of the coupling between triboelectrification and electrostatic induction. However, all of the previously demonstrated TENG...

Fluid phase separations of racemates are difficult because the subtle, short-ranged differences in intermolecular interactions of like and unlike pairs of chiral molecules are typically smaller than the thermal energy. A surface restricts the configurational space available to the pair of interacting molecules, thus changing the effective interactions between them. Because of this restriction, ...

â a model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. while the model’s solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the cpu time is decreased ess...

We present a computational investigation of the mechanism governing size-based particle separation in microfluidic pinched flow fractionation. We study the behavior of particles moving through a pinching gap (i.e., a constriction in the aperture of a channel) in the Stokes regime (negligible fluid and particle inertia) as a function of particle size. The constriction aperture is created by a pl...

The retention mechanism of electrostatic ion chromatography (EIC) is currently under debate and is the focus of this paper. A comprehensive set of retention data has been obtained on a C18 column coated with the zwitterionic surfactant 3-(N,N-dimethylmyristylammonio)propanesulfonate used with a range of mobile phases in which both the mobile-phase anion and cation have been varied systematicall...
