Automatic speech recognition systems have the potential to make hard to understand speech more easily recognizable. Designing a system that recognizes impaired speech is more difficult than a system that recognizes normal speech. The Automatic Malay Speech Recognition for Speech Disorder system is able to recognized impaired Malay words spoken by people who suffer from dysarthria, a motor speech disorder resulting from neuron damage, characterized by poor communication. It is developed using techniques used for normal speech recognition but modified to cater for the speech impairment. A feature extraction technique based on the Mel Frequency Cepstrum Coefficient (MFCC) is used along with artificial intelligent algorithms to recognize the speech. In addition, novel pre-processing steps are required to segment the speech prior to recognition taking into account the speech irregularities. The system requires that the user is registered with the system and the system is then trained to accommodate the user speech pattern. The outputs of the system are the visual display of the corrected words uttered or synthesized audio version of the corrected words.

Speech compression is one area of digital signal processing that focusing on reducing the bit rate of the speech signal for transmission or storage without significant loss of quality. In recent years a new technique called wavelet transform has been proposed for signal analysis. It has been successfully used in image compression application. So far, less attention has been paid to the research in the speech compression . using wavelet. This paper attempts to evaluate the wavelet compression technique on speech signals Different wavelet filters were used to select the best filter suitable for speech signal in providing low bit rate and IOW computation complexity. Our implementation was evaluated base on PSNR, SNR, NRMSE and compression ratio tested on 8 kHz bit speech signals. This algorithm was also compared to the following speech compression schemes: Linear Productive Coding (LPC) which reduces the transmitted data by factor of more than twelve, and Global system Mobile (GSM) which reduces the transmitted data by factor of five As a result from this study, wavelet speech compression gives higher SNR and better speech quality than the other techniques. © 2003 IEEE.

Face annotation for personal photos has a number of potential applications in Multimedia Information Retrieval (MIR). We propose a novel face annotation method that systematically combines contextual information of photos with traditional Face Recognition (FR) technologies. To overcome the limitations of conventional FR-based annotation approaches, situation and person clustering methods are proposed based on context of personal photos. By relying on the proposed clustering methods, multiple facial images that belong to the same person are applied to subspace FR methods. This allows traditional FR methods to take advantages of feature- or measurement-level fusion strategies for automatic annotation of faces on personal photos. The effectiveness of the proposed method was successfully tested on 1,120 personal photos selected from standard MPEG-7 Visual Core Experiment 3 (VCE-3). Extensive experimental results showed that the proposed method improves annotation accuracy by at least an order of magnitude, compared with conventional FR-based approaches. Copyright 2008 ACM.

The main deficiency of standard TCP and all existing variations in ad hoc mobile network arises in its inability to classify packet losses. Conventional TCP diagnoses all losses due to congestion since non-congestion losses are rare and ignorable in wired network. However, these losses are generated frequently in MANET due to signal attenuation, interference and node's mobility. In order to prevent TCP form invoking congestion control over non-congestion loss and vice versa, Packet loss classification with high accuracy is desirable. This paper proposes an end-to-end sender-side approach which aims to classify congestion loss, wireless channel loss and link failure loss using queue usage estimation. Relative One-way Trip Time is key factor in calculating queue usage. Packet losses with queue usage rate greater than predefined threshold is always interpreted as congestion loss no matter how loss recognized. However, queue usage less than threshold signify presence of non-congestion losses. Non-congestion loss which recognized by three duplicate ack labels loss due to wireless channel error since it is indication of route existence between communicating end point that duplicate ACKs moved along. However Non-congestion loss which recognized after retransmission timer expiration has been probably due to link failure. Different approaches efficiency are evaluated based on loss classification's accuracy under different conditions such as various flow numbers, various wireless loss rates and variable speed for nodes. Simulations illustrate that obtained accuracy of enhanced scheme is the highest among proposed methods. © 2011 IEEE.

E-health is closely related with networks and telecommunications when dealing with applications of collecting or transferring medical data from distant locations for performing remote medical collaborations and diagnosis. In this book we provide an overview of the fields of image and signal processing for networked and distributed e-health applications and their supporting technologies. The book is structured in 10 chapters, starting the discussion from the lower end, that of acquisition and processing of biosignals and medical images and ending in complex virtual reality systems and techniques providing more intuitive interaction in a networked medical environment. The book also discusses networked clinical decision support systems and corresponding medical standards, WWW-based applications, medical collaborative platforms, wireless networking, and the concepts of ambient intelligence and pervasive computing in electronic healthcare systems.

A DISTRIBUTED PROBLEM-SOLVING system FOR SHORT-TERM LOAD FORECASTING

引用

ELECTRIC POWER systemS RESEARCH 1993年第3期26卷 219-224页

Based on the attractive features of both distributed artificial intelligence and existing load forecasting techniques, a distributed problem solving system for short-term load forecasting is proposed. Such a distributed paradigm is a multi-agent system, each processing agent of which can compute autonomously and cooperate with other agents to reason an accurate and satisfactory solution for load forecasting. The designed load forecasting system solves problems using three basic modules: a blackboard module, knowledge sources, and a control mechanism. In addition, to achieve a high degree of accuracy in load forecasting, the existing techniques are embedded in the domain knowledge source and the root mean square error is referred to as the key driven by the constraint knowledge source. This system has been implemented by the expert system tool CLIPS in a SUN network environment and tested with practical data. It was found that the developed distributed system is a valuable tool for system operators for short-term load forecasting.
