A multi-output second generation current conveyor (MOCCII), that can be used to realized first, second and third generations current conveyors, is proposed. The MOCCII consists of a CMOS differential stage for the voltage input, push-pull stage and the improved cascode current mirrors for the current output. Feedback techniques are proposed in order to provide a voltage gain of 0.991, a current...

This paper discusses a novel architecture for a Hybrid Fiber Radio (HFR) access network using Software Defined Radio (SDR) in a combined Base Station (BS) headend unit. While most of the current SDR approaches consider software radio to be used in the portable terminals to allow multi-mode operation, we propose a SDR-HFR based access network architecture. The combination of HFR and SDR allows s...

In this paper various representations of the exceptional Lie algebra G2 are investigated in a purely algebraic manner, and multi-boson/multi-fermion realizations are obtained. Matrix elements of the master representation, which is defined on the space of the universal enveloping algebra of G2, are explicitly determined. From this master representation, different indecomposable representations d...

Business transactions of today often rely on the involvement of several organizations in its preparation and realization. This means that value creation is distributed among several actors and needs to be coordinated. The division of multi-organizational businesses into business processes need to reflect the co-production of value arranged in distributed value production structures. There relie...

Multi-tenancy is an essential property of Cloud computing. It helps service providers to maximize resource utilization and reduce servicing costs per customer. It is therefore important for key components of the contemporary enterprise environment like the Enterprise Service Bus (ESB) to support and enable multi-tenancy. For this purpose, in this work we investigate the requirements for multi-t...

A general multi-step N 7−→ M probabilistic optimal universal cloning protocol is presented together with the experimental realization of the (1 → 3) and (2 → 3) machines. Since the present method exploits the bosonic nature of the photons, it can be applied to any particle obeying to the Bose statistics. On a technological perspective, the present protocol is expected to find applications as a ...

This paper copes with the problem of integrating peer-to-peer and multi-agent systems for the realization of both large-scale multi-agent systems and sophisticated peer-to-peer applications. In particular, it presents how JADE, one of the best known and most used software framework for the development of multi-agent systems, has been extended with a peer-to-peer technology, and how a JADE multi...
