Meeting Medical Terminology Needs: The Ontology-Enhanced Medical Concept Mapper, Gondy Leroy, Hsinchun Chen

CGU Faculty Publications and Research

This paper describes the development and testing of the Medical Concept Mapper, a tool designed to facilitate access to online medical information sources by providing users with appropriate medical search terms for their personal queries. Our system is valuable for patients whose knowledge of medical vocabularies is inadequate to find the desired information, and for medical experts who search for information outside their field of expertise. The Medical Concept Mapper maps synonyms and semantically related concepts to a user's query. The system is unique because it integrates our natural language processing tool, i.e., the Arizona (AZ) Noun Phraser, with human-created …

An Object-Oriented Resource Pool Model In Support Of Discrete Event Simulations, Srinivas Gullapalli

Electrical & Computer Engineering Theses & Dissertations

The proper distribution of resources is a key factor in simulation. Resources provide the supporting facilities, equipment, and personnel for carrying out activities. The number of resources has a direct impact on the overall effectiveness of the simulation as it does in real life. If the number is insufficient, it generally takes more time for the process to complete. On the other hand, if the number is too high, the cost incurred on the resources will be unnecessarily large. Therefore, the count should be a compromise between the two extremes.

In this thesis, an attempt is made to generalize the …

Computer software is emerging as a powerful tool for controlling a large number of instruments and for the testing of these instruments. The main aim of this work is to provide a software program capable of controlling a large number of engineering instruments at the touch of a button. In addition, the software is to have the capability of connecting the instruments with the desired Unit Under Test. There is great need for such software driven testing in industry, especially for large complex systems. Advantages of such an approach include: (a) automated testing in a very quick and efficient manner; …

Minimum Mean Square Error Spectral Peak Envelope Estimation For Automatic Vowel Classification, Jaishree Venugopal

Electrical & Computer Engineering Theses & Dissertations

Spectral feature computations continue to be a very difficult problem for accurate machine recognition of speech. In this work, which focuses on vowels, a new spectral peak envelope method for vowel classification is developed, based on a missing frequency components model of speech recognition. According to the missing frequency components model, vowel recognition depends only on the spectral (harmonic) peaks. Smoothing and interpolation of the spectra, performed in the standard cepstral analysis method commonly used in automatic speech recognition, actually loses valuable information and results in reduced recognition accuracy. The new method for feature extraction presented in this thesis is …

Vhdl Implementation For Jawi Character Recognition, Mustafa Norita Adila

Student Works (2000-2009)

Kewujudan tulisan jawi sejak dahulu lagi telah menghasilkan pelbagai karya penting dalam perkembangan islam. Sebagai satu bahasa pengantara, tulisan jawi dianggap penting dalam bidang penulisan. Tidak terhad hanya kepada buku-buku, dokumen-dokumen dan manuskrip-manuskrip yang ditulis dalam tulisan jawi, malah penggunaanya amat meluas dan meliputi keseluruhan bidang. Menyedari kepentingannya, timbul minat saya untuk mengkaji dengan lebih mendalam bagaimana komputer boleh mengenali dan memahami tulisan ini tanpa menggunakan tenaga manusia berdasarkan kepada beberapa kajian yang sedia ada yang telah dijalankan oleb mereka yang pakar dalam teknologi komputer digital. Secara keseluruhan, kajian ini akan membantu memudahkan lagi pengecaman tulisan tangan jawi yang dilakukan …

Development Of Object-Oriented Components For Atm Network Simulation With Emphasis On Schedule Policies In Traffic Shaping, Chee Sum Wong

Student Works (2000-2009)

Asynchronous Transfer Mode (ATM) is considered to be the ground which B-ISDN is to be built. The traffic control of ATM network is important to provide Quality of Service (QoS) for network applications Therefore, different traffic management procedures have been introduced to achieve network performance objectives. Traffic shaping is one of the traffic management mechanisms that able to protect the network and the end-system from congestion probleam. This project focuses on the development for simulation of different scheduling policies in traffic shaping with object-oriented approach. The simulator is designed and implemented to ensure the correctness of scheduling within the network …

The Partial Evaluation Approach To Information Personalization, Naren Ramakrishnan, Saverio Perugini

Computer Science Faculty Publications

Information personalization refers to the automatic adjustment of information content, structure, and presentation tailored to an individual user. By reducing information overload and customizing information access, personalization systems have emerged as an important segment of the Internet economy. This paper presents a systematic modeling methodology— PIPE (‘Personalization is Partial Evaluation’) — for personalization. Personalization systems are designed and implemented in PIPE by modeling an information-seeking interaction in a programmatic representation. The representation supports the description of information-seeking activities as partial information and their subsequent realization by partial evaluation, a technique for specializing programs. We describe the modeling methodology at a …

Messaging Application, Hooi Phaik Yew

Student Works (2000-2009)

Statistics have shown that more and more people are switching to WAP (Wireless Application Protocol) handphones and most people would have heard of WAP before. Undeniably WAP's future is bright and WAP applications prospects are even better. This alone has encouragrd many programmers into developing WAP applications. Study had shown that this is true in part of the world with more and more hooking up to WAP hand phones. Internet Messaging programs have existed for a long time. Currently there's no WAP Messaging Application (WAP-MA) but it's just a matter of time before somebody invented it. This project is involved …

Learning Recursive Functions Refutably, Sanjay Jain, Efim Kinber, Rolf Wiehagen, Thomas Zeugmann

School of Computer Science & Engineering Faculty Publications

Learning of recursive functions refutably means that for every recursive function, the learning machine has either to learn this function or to refute it, i.e., to signal that it is not able to learn it. Three modi of making precise the notion of refuting are considered. We show that the corresponding types of learning refutably are of strictly increasing power, where already the most stringent of them turns out to be of remarkable topological and algorithmical richness. All these types are closed under union, though in different strengths. Also, these types are shown to be different with respect to their …

The Design Of 3d Cyberspace As User Interface: Advantages And Limitations, Maria Borisovna Quick

Theses : Honours

Virtual reality propagandists, technologists and the Internet community have long debated the issue of the usability of online three-dimensional (3D) environments. A lot of work was published about the benefits of 3D spaces for human-computer interaction and information visualisation due to their realism (Anders, Kalawsky, Crossley, Davies, McGrath, Rejman-Greene, 1998, Hamit, 1993, Heim, 1992, Aukstakalnis, Blatner, Roth, 1992). This topic also receives continuous industry support including standardisation of Virtual Reality Modeling Language ( VRML, VRML Consortium, 1997) and the more recent Macromedia & Intel alliance "to bring web 3D to the mainstream" (200 1, Intel Corporation). The actual implementation …

Unified Modeling Language: A Complexity Analysis, Keng Siau, Q. Cao

Research Collection School Of Computing and Information Systems

Unified Modeling Language (UML) is the standard visual modeling language for Object Oriented (OO) systems development, but it has been criticized for its complexity, inconsistent semantics, and ambiguous constructs. A set of complexity indices for UML and the nine diagramming techniques in UML was compiled recently. The complexity analysis is formulated based on the number of constructs, associations, roles, and so forth, in a modeling method. We argue that this set of metrics provides an indication of the theoretical complexity of the modeling methods. On the other hand, the theoretical complexity of the modeling methods does not necessarily relate to …
