In this paper, Mirror sites enable client requests to be serviced by any of a number of servers, reducing load at individual servers and dispersing network load. Typically a client requests service from a single mirror site. We suggest a way for the client to access a file from multiple mirror sites in parallel to speed up the download. We have developed a technique that can deliver dramatic sp...

We endogenize circulation of currencies and price formation in a decentralized monetary trading environment with two countries and two currencies. In equilibrium sellers of homogenous goods may post prices in the national or also in the foreign currency, given unobservable buyers’ valuations. We prove that, under different monetary regimes, the absence of well integrated international goods mar...

Automatic labelling and identification of cerebral structure, such as cortical sulci, are useful in neurology, surgery planning, etc... In this paper, a method to detect the valley of the cortical sulci is presented. The aim of the method is to achieve the sulci medial surface. The method applied on MRI data, is based on geometrical features (curvature) which doesn’ t require the accurate segme...

The initial clinical manifestations of the Anderson Fabry Disease are unspecific and analizing them independently doesn ́t leave to a specific diagnosis. This is why at this time, this disease represents a diagnostic challenge. A prompt identification and determination of signs and symptoms in the pediatric patients will lead to an opportune disease diagnosis and an early enzymatic replacement t...

We present an object recognition architecture based on feature extraction by Gabor filter kernels and feature classification by an artificial neural network. The parameters of the Gabor filters are optimized to the specific problem by minimizing an energy function. Such Gabor filters extract features that can be more easily classified by the neural network. Moreover the feature space is low-dim...

In this paper we propose a novel approach for the systematic assessment and analysis of IT related risks in organisations and projects. The approach is model-driven using an enterprise architecture as the basis for the security management process. Using an enterprise architecture it is possible to provide an integrated description of an organisation’s structure, processes and its underlying IT ...

IT risk management is an important challenge for businesses and software vulnerabilities are a major source of IT risks, as the 2006 CSI/FBI Computer Crime and Security Survey [GLLR06] demonstrates. According to the survey, many companies consider it important to quantify the losses attacks against their IT systems cause but are unable to do so. In service-oriented architectures, we see a promi...
