In this paper we present a CORBA-based architecture for electronic auction applications. The core of this architecture is represented by two services, which considerably facilitate the implementation of an electronic auction house by performing some of the main tasks that typically have to be implemented by a developer in this context, such as distributing and recollecting bidding data. Besides...

As the shift towards the next generation of services runs its course, the emphasis within accounting for such services has moved towards robust and flexible components. An accounting architecture with the ability to scale, based on the foundation of a solid core of rating components, incorporating transaction management, object pooling and queuing is presented. Using the workbook approach to al...

Recent biomedical hydrogels applications require the development of nanostructures with controlled diameter and adjustable mechanical properties. Here we present a technique for the production of flexible nanofilaments to be used as drug carriers or in microfluidics, with deformability and elasticity resembling those of long DNA chains. The fabrication method is based on the core-shell electros...

A technique for enhanced generation of selected high harmonics in a gas medium, in a high ionization limit, is proposed in this paper. An aperiodically corrugated hollow-core fiber is employed to modulate the intensity of the fundamental laser pulse along the direction of propagation, resulting in multiple quasi-phase-matched high harmonic emissions at the cutoff region. Simulated annealing (SA...

We present the development of a flexible polyimide substrate that act as the conduit for power and signal transmission with the additional features of precise control of the metal trace geometries. Using microfabrication techniques, a metal trace is fabricated that possesses a flexible polyimide-based interconnection. The performance of the design was measured with multimeter. The HFSS simulati...

E-Business modelling and ebusiness systems development assumes fixed company resources, structures, and business processes. Empirical and theoretical evidence suggests that company resources and structures are emergent rather than fixed. Planning business activity in emergent contexts requires flexible ebusiness models based on better management theories and models . This paper builds and propo...

As a basis to improve software engineering education, comprehensive information is needed on learning and teaching arrangements and experiences that have been made with these arrangements, covering a wide range of aspects. In addition, this information needs to be analyzed in a flexible manner in order to identify suitable arrangements that might be adapted for future use in a specific software...

For flexible mapping of various task-level pipelines on a multi-core processor, the authors proposed the memory-centric network-on-chip (NoC). The memory-centric NoC manages producer–consumer data transactions between the tasks in the case of task-level pipelines are distributed over multiple processing cores. Since the memory-centric NoC manages the data transactions, it relieves burden of the...

H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...

In this work, CoMoO4@NiMoO4·xH2O core-shell heterostructure electrode is directly grown on carbon fabric (CF) via a feasible hydrothermal procedure with CoMoO4 nanowires (NWs) as the core and NiMoO4 nanosheets (NSs) as the shell. This core-shell heterostructure could provide fast ion and electron transfer, a large number of active sites, and good strain accommodation. As a result, the CoMoO4@Ni...
