For the goal of cardiovascular disease risk detection, the statistic analysis is used to reduce the dimension of feature space and normalize each input feature; the modified Takagi-Sugeno model fuzzy neural networks are applied to realize the nonlinear mapping relationship between hemodynamic parameters and conclusions, which does not require predefining rules and subjective defuzzification. The preliminary testing results prove that the proposed method is promising for e-home healthcare usage.

Healthcare organisations using the European Foundation for Quality Management (EFQM) Excellence Model for self-assessment have found an opportunity to work more effectively and a powerful driver for improvement. Nevertheless, when these organisations address self-assessment processes for the first time the initial effort needed presents many difficulties. The aim of this paper is to offer a consensus support methodology based on fuzzy logic under a linguistic approach that would undoubtedly contribute to conduct self-assessment processes with questionnaires. We assume qualitative evaluation, through linguistic labels, to facilitate the individual responses, and we use the concept of fuzzy majority to calculate the measures which guide the consensus reaching process.

The current researches to improve the reliability of operating systems have been focusing on the evolution of kernel architecture or protecting against device driver errors. In particularly, the device driver errors are critical to the most of the complementary operating systems that have a kernel level device driver. Especially on special purpose embedded system, because of its limited resources and variety of devices, more serious problems are induced. Preventing data corruption or blocking the arrogation of operational level is not enough to cover the entire problems. For examples, when using device drivers, the violation of function's call sequence can cause a malfunction. Also a violation of behavior rules on system level involves the same problem. This type of errors is difficult to be detected by the previous methods. Accordingly, we designed a system that traces system behavior at runtime and recovers optimally when errors are detected. We experimented in Linux 2.6.24 kernel operating on GP2X-WIZ mobile game player.

A frequency domain correlator (FDC) with low-complexity architecture is proposed. This signal processing module is part of FFT-based acquisition stage of a global position system (GPS). The FDC is based on a single reconfigurable core capable of computing both decimation in frequency radix-2 (DIF-2) fast Fourier transform (FFT) and decimation in time radix-2 (DIT-2) inverse fast Fourier transform (IFFT). The proposed FDC reuses the reconfigurable core together with appropriate decimation choice, providing an improvement in resource management while avoiding any additional reorder data hardware. Additionally, the FDC architecture shows a great flexibility due to three levels of parameterization which allows to fix the number of complex input samples, data width and word format. The architecture has been implemented in Altera Cyclone II and Xilinx Virtex II Pro for N-points correlation with different word lengths. The simulation and synthesis results shows that the FDC is suitable for performing acquisition stage in GPS, enabling its utilization in software define radios.

The IEC61499 is an open standard for distributed control and automation. The interface between control software and hardware or communications is achieved by means of the so-called Service Interface Function Blocks (SIFB). This paper presents the guidelines to build communication SIFBs based on the emerging OMG DDS (Data Distribution Service) middleware. This specification implements in a very efficient way the Publisher/Subscriber paradigm providing significant QoS configuration possibilities. These characteristics make DDS suitable for implementing the communications among time-critical devices. By using these DDS-SIFBs within IEC61499 code generation tools, the designers of the distributed applications will be allowed to use this powerful technology in the new distributed applications.

In this paper we consider disturbance decoupling problems for switched linear systems. We will provide necessary and sufficient conditions for three different versions of disturbance decoupling, which differ based on which signals are considered to be the disturbance. In the first version the continuous exogenous input is considered as the disturbance, in the second the switching signal and in the third both of them are considered as disturbances. The solutions of the three disturbance decoupling problems will be based on geometric control theory for switched linear systems and will entail both mode-dependent and mode-independent static state feedback.
