This method applies the same framework as is are used for training speech recognizers with abundant training data. The Baum-Welch adaptation method is adapted to all the parameters of the hidden Markov models (HMM) with adaptation data. If a large amount of adaptation data is available, these methods could gradually approximate the speaker-dependent ones. The approach is evaluated through the phoneme recognition task on the TIMIT corpus. On the speaker adaptation experiments, up to 91.48% recognition rate is achieved.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.

This paper analyzes the fault-tolerance and performance abilities of the proposed Phi network and compares it with its predecessor, the Omega network. The reduced numbers of stages of the designed MIN diminish the latency within the network markedly. The methods for routing permutations in the presence and absence of faulty components in both the networks have been analytically compared. The irregular nature of the Phi network allows 50% of the permutations to pass at the minimum path length of 2 whereas others pass at adaptable path length counting on the status of the path, largest being log/sub 2/N for a network of size N. The bandwidth of the new network shows optimal benefits. Bounds on reliability exhibit graceful degradation with time showing distinct gains over Omega where it reduces drastically, increasing the time between failures of the system. The comparison of these networks shows that irregular Phi network is a preferred choice to be used in the high-speed multiprocessor environment.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.

Up to date, physical therapists have not known patient vital signs exactly during physical therapy. This paper focuses on the measurement and analysis of biomedical signals using the telemetry technique with portable devices for exercising patients. The system measures the patient heart rate and respiration rate simultaneously and the collected signals are transmitted by a portable unit and received by a stationary device that is combined with a PC for analyzing and displaying in real time. This paper concentrates on removing unnecessary noise and motion artifacts using compensation hardware and software algorithms. The system could help to calculate the patient's present quantity of exercise and compare it with the maximum quantity of exercise of physiological permission to decide the term of physical therapy and check the patient's vital safety.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.

Thermal calculations, especially in nonconventional machines in which there is only limited information about heat dissipation, is an important stage in machine design. SRM is such a machine hence necessitating a defined methodology to carry out thermal analysis; this paper intensely attempts and provides a simulation method for thermal analysis. The thermal flux plot, the isothermal distribution, thermal gradients in different parts of SRM at its different rotor positions and the respective governing equation are presented. It is believed that this is the first time, a full length paper is totally devoted to discuss in simple terms the thermal distribution in SRM through FE methods.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.

The proposed system aims to overcome the problems of audible echoes in a simple echo hiding approach. Audibility of echoes is reduced especially for problematic signals by the application of signal-based attenuation, psycho-acoustic model and perceptual filter to adaptively modify the decay rate used in encoding the watermark. The proposed method is robust to common signal processing operations of noise addition, re-sampling, cropping, filtering and MPEG coding. If inaudibility and detection accuracy are of paramount importance, a psychoacoustic model coupled with single echo is the most appropriate encoding option to use when additional signal processing is imposed. The application of multiple echo hiding is also investigated. It is found that although multiple echo hiding improves inaudibility in general, detection accuracy is compromised when additional signal processing is imposed.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.

In spite of its promises, mobile agent systems have not gained substantial acceptance because of the security concerns that have not been adequately addressed yet. In this paper, we propose an architecture that allows user programs to run on third party hosts called Surrogate hosts. The architecture presents a hybrid approach utilizing both mobile agent paradigm as well as client-server paradigm. Apart from extending the computing power of the user system, the proposed surrogate host system allows users to run their applications while the user system remains disconnected. The proposed architecture reduces the stringency of security requirements of mobile agents based systems, is scaleable and uses a load balancing mechanism to evenly distribute the user programs.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.

For example, E-COIRS supports the query 'retrieve images that a black home appliance is to north of reception set'. The query includes two types of concepts: IS-A and aggregation-'home appliance' is an IS-A concept, and 'reception set' is an aggregation concept. For evaluating such a query, E-COIRS includes three Important components: a visual image indexer, thesauri and a query processor. Each pair of objects in an image captured by the visual image indexer is converted into a triple. The triple consists of two object identifiers (oids) and their spatial relationship. All the feature of an object is referenced by its old. The thesauri, which are mainly used by the query processor to detect concepts, consist of a triple rule-based thesaurus and a term thesaurus. The query processor obtains an image set associated with each triple in a user query by looking up an inverted file and CS-Tree. To support efficient storage use and fast retrieval on high-dimensional feature vectors, E-COIRS uses a new Cell-based Signature tree. E-COIRS is a more advanced content-based image retrieval system than other systems which support only concepts or image features.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.
