In this paper we present the application of a particular neuro-fuzzy system, named KERNEL, to the problem of differential diagnosis of erythematosquamous diseases, which represents a major problem in dermatology. A multistep learning strategy is adopted to obtain, starting directly from available data, a fuzzy rule base that can be used to identify the particular disease. The obtained classific...

This work arises from the purpose of applying new tools in dynamical systems to time problems in biological systems. The main aim of this paper is to develop a numerical method to perform the effective computation of the phase advancement when we stimulate an oscillator which has not yet reached the asymptotic state (a limit cycle). That is, we want to extend the computation of the phase resett...

When metadata is distributed across many metadata servers in a distributed file system with a locality-preserving metadata distribution unit like a directory, simply increasing the number of metadata servers does not give high-aggregate performance for the metadata operation such as file creation. This paper proposes an effective and consistent method for processing metadata operations, at low ...

The goal of the HERMES project was to conceive means to integrate existing heterogeneous database products in a transaction management system. The project produced the 2PC Agent method based on the 2PC protocol. The method is based on simulation of the prepared state at participating sites and it guarantees serializable executions in the presence of site and transaction failures. A restriction ...

Soccer simulation is an effort to motivate researchers and practitioners to do artificial and robotic intelligence research; and at the same time put into practice and test the results. Many researchers and practitioners throughout the world are continuously working to polish their ideas and improve their implemented systems. At the same time, new groups are forming and they bring bright new th...

In this paper we consider one-dimensional two-phase Stefan problems for a class of parabolic equations with nonlinear heat source terms and with nonlinear flux conditions on the fixed boundary. Here, both timedependent and time-independent source terms and boundary conditions are treated. We investigate the large time behavior of solutions to our problems by using the theory for dynamical syste...

Two-phase micro-pipeline asynchronous modules show faster performance than common four-phase control systems, but the conventional systems with multi-port modules normally suffer from long signal paths on stacked C-elements. NOR-based control schemes provide an alternative solution to problems such as propagation delay. This paper compares modified versions of these two popular pipelined system...

Data management in network systems is different from that in traditional data systems. It is important to ensure data consistency not only between network management systems, but also between network elements, which may not support database protocols such as two-phase commit, as well as between network management systems and network elements. The problem is nontrivial, especially when data are ...
