In an age where information has become a crucial commodity, accessing appropriate information quickly is essential to economic success. Developing ways of improving information retrieval is therefore of central concern to human factors and technologists alike. One aspect of information access relates to the ability of individual office workers to manage and retrieve their own information effectively, and this is what the present research addresses. Previous work in the area has been dominated by designing computer interfaces for the average user. This research investigates how people's needs might differ according to circumstance and examines a wider range of design possibilities. Specifically it sets out to relate retrieval problems (specific information retrieval rather than e.g. browsing or reminding) to job and individual (personality) differences within the general context of personal information management in offices using traditional technologies of paper, filing cabinets and desks. This is achieved by both extensive fieldwork and the use of simulated filing-retrieval systems in a controlled context.

We have examined the technique of persistent spectral holeburning as a method for analog optical data storage. Two types of materials were examined from a theoretical standpoint, ones which exhibit photochemical holeburning (PHB) and ones which exhibit nonphotochemical holeburning (NPHB). We have presented the conditions under which a PHB material shows a linear relation between hole depth and exposure intensity or exposure time. Also we show that a NPHB material has no such condition. We conclude that a PHB material may be useful for analog optical data storage, while a NPHB material would not. Experiments were conducted with a NPHB material, R' color centers in LiF, to support the NPHB analysis.

The necessity for a functional user friendly laboratory data management program has become evident as the quantity of information required for modern scientific research has increased to to titanic proportions. The required union of strong computer power, ease of operation, and adaptability have until recently been outside the realm of most research laboratories. Previous systems, in addition to their high cost, are necessarily complex and require software experts in order to effect any changes that the end user might deem necessary. This study examines the Apple Macintosh computer program Hypercard as an interactive laboratory information system that is user-friendly, cost effective, and adaptable to the changing demands within a modern molecular or microbiology.

Search is becoming the primary way in which people get information. In 2010, global Internet usage was over two billion people, with 92% of online adults using search engines to find information. Most commercial search engines (Google, Yahoo, Bing, etc.) provide their indexing and search services at no cost. The DoD can achieve large gains at a small cost by making public documents available to search engines. This can be achieved through the utilization of important design components and effective knowledge management. This thesis examines methods for making information available to search engines at the Naval Postgraduate School (NPS) and the Defense Technical Information Center (DTIC). In a large-scale project, over 200,000 documents were organized on the website dodreports.com. The results of this research revealed improvement gains of 8-20% for finding reports through commercial search engines during the first six months of implementation.

The CODER (COmposite Document Expert/Extended/Effective Retrieval) project is a multi-year effort to investigate how best to apply artificial intelligence methods to increase the effectiveness of information retrieval systems. Particular attention is being given to analysis and representation of heterogeneous documents, such as electronic mail digests or messages, which vary widely in style, length, topic, and structure. In order to ensure system adaptability and to allow reconfiguration for controlled experimentation, the project has been designed as a moderated expert system. This thesis covers the design problems involved in providing a unified architecture and knowledge representation scheme for such a system, and the solutions chosen for CODER. An overall object-oriented environment is constructed using a set of message-passing primitives based on a modified Prolog call paradigm. Within this environment is embedded the skeleton of a flexible expert system, where task decomposition is performed in a knowledge-oriented fashion and where subtask managers are implemented as members of a community of experts. A three-level knowledge representation formalism of elementary data types, frames, and relations is provided, and can be used to construct knowledge structures such as terms, meaning structures, and document interpretations. The use of individually tailored specialist experts coupled with standardized blackboard modules for communication and control and external knowledge bases for maintenance of factual world knowledge allows for quick prototyping, incremental development, and flexibility under change. The system as a whole is structured as a set of communicating modules, defined functionally and implemented under UNIX™ using sockets and the TCP/IP protocol for communication. Inferential modules are being coded in MU-Prolog; non-inferential modules are being prototyped in MU-Prolog and will be re-implemented as needed in C++.

Informationssystem är resultatet av samarbete människor emellan. System designas, realiseras, testas och implementeras i de verksamheter som de ska stödja. Samarbetekrävs under alla dessa steg. I utvecklingsarbetets inledning är det inte ovanligt att kraven på systemen formuleras genom projekt som organiseras genom olika typer avsamarbetsformer. I föreliggande avhandling lyfter vi pä locket på samarbetsinriktad modellering och studerar i detalj vad som sker när krav på system formuleras. Genom en gedigen forskningsdesign och ett rikt datamaterial följer vi två modelleringsteam när de facililerar verksamhetsrepresentanter i olika situationer under tre modelleringsprojekt. Avsikten är att utveckla kunskap om vad som utmärker facililering i dessa situationersamt studera vad som utmärker situationsanpassning när modellerarna underlättar och möjliggör arbetet. Genom videobaserad forskning har modelleringsarbetet dokumenterats och med hjälp av olika analysmetoder, såsom konversationsinriktad handlingsanalys och multigrundad teoriutveckling, tolkas episoder i materialet och en plattform för en praktisk teori om facililering utvecklas. Resultatet utgörs av en typologi över samarbetsinriktad modellering, åtgärder för att utföra facililering av arbetet, samt insikter om vad som utmärker situationsanpassning när facilitering utförs och olika omständigheter måste mötas. Synsättet som förespråkas är att tillämpande av struktur och utnyttjandet av frihet är förutsättningar då goda krav på informationssystem ska formuleras genom samarbete.

This thesis encompasses a Welding Information System for Design, Operations, and Methods (WISDOM). In essence, the WISDOM project aimed at research and development of an innovative and comprehensive information collection on welding in close cooperation with industry utilizing modern micro-computer techniques of information review, retrieval, storage, updating, and transfer. Emphasis is placed on new and more efficient methods of knowledge communication, pursuing the idea of exploring knowledge (in contrast to rehearsing recipes). The development of this project concentrated on the following three main topics: 1. Background information on steel metallurgy and welding 2. Analysis and Design Methods for Welded Connections 3. Code Requirements of Welds Preliminary research on the WISDOM project involved communications with industry to determine primary objectives. The need for an information system on welding was unquestionably apparent. The knowledge base is supplemented with graphic images and analysis and design programs. It is hoped that the information in this system will be delivered to the engineer in an efficient and useful manner. The priority here is to raise welding awareness while promoting efficient welded design. In addition, we hope that the WISDOM system will close the ever widening gap between the design engineer and the fabricator. In the most general sense, the primary objective of the WISDOM project was to produce an integrated self-paced teaching tool for both engineering professional and student alike. The versatility of the system is maintained by presenting the information in modular form. Screen graphics oriented learning modules encourage the user to become more involved in the learning process than more conventional teaching methods allow. Analysis and design modules promote rapid and efficient connection design in a more consistent and professional manner. A smooth transition from the learning environment to engineering practice is envisioned by providing realistic design tools with a transparent background.

The ability to identify particular features and structures, such as faces or types of scenery in images, is a topic with many available applications and potential solutions. In this paper we discuss solar images and the results of our preliminary investigation of techniques that can be used to identify solar phenomena in images from the TRACE satellite. Being able to automatically identify various phenomena in solar images is of great interest for scientists studying phenomena on the sun. A set of characteristics that can be quickly extracted from solar images needs to be acquired. These characteristics are used to create classifiers for various phenomena contained in solar images. There are many obstacles that need to be overcome when extracting features and creating these classifiers. These include the inherent unbalanced data sets due to varying rates at which different phenomena appear and multiple phenomenon that could appear in each image. The classifiers that have been generated were used in the creation of an information retrieval system to make finding phenomenon solar images quick and easy.

Decisions are made with varying degrees of effectiveness and efficiency and are influenced by a myriad of internal and external forces. Decision Support Systems (DSS) software can effectively aid decision making through processing the facts and producing meaningful outputs for use by the person or team in making the final choice. Geographic Information Systems (GIS), a form of DSS, are very effective when locational data are present. This thesis talks about using GIS software in decision making procedures.

Most current approaches to Information Systems Development (ISD) tend to derive from past experience and practice, rules of thumb and technology trends. The lack of theoretical foundations hinders the systematic development and evaluation of new ISD methodologies. The research undertaken in this thesis addresses this issue by proposing a formal, theory-based model, Ontology/Object-Based Conceptual Modelling (OBCM), for conceptually representing IS applications. The formalism is novel in that it is grounded in first principles derived from metaphysics, in particular the system of Ontology developed by Mario Bunge. Underlying this approach is the premise that an Information System is a model of reality and that model should be therefore rooted in a theory of reality, ie. a metaphysics. As a result, basic assumptions in reality such as thing, substance, property, attribute, time, state and change are explicitly and rigorously addressed. OBCM features an ontologically well-defined construct, "object", which is used to directly represent entities in reality, thus lending theoretical credence to the so-called object-oriented paradigm found in recent programming languages and databases. In addition, the thesis presents a framework, Ontology/Object-Based Information System (OBIS), for systems implementation based on this model. This framework directly implements the object construct so that it can be immediately utilized by the information systems user in a "direct manipulation" style of end-user interaction. Further, OBIS strives for a single, homogeneous concept of system operation drawn from ontology rather than in terms of IS or computing technology. In principle, this one concept can be applied to any object in the IS, this simplifying the understanding and use of the Information System. In this way, the model attempts to unify the analysis, implementation and user-interface aspects of Information Systems Development, thereby reducing the so-called "semantic gap" which has often been observed between the reality of the application and its final implementation in an IS. A "proof of concept" prototype is described which illustrates the main principles and explores practical applications of the proposed model. This prototype is implemented as a single, stand-alone "shell" which can be used to support a wide variety of applications as well as providing the basis of a rapid prototyping or CASE tool. The prototype is used to implement sample problems including the well-known IFIP Working Conference problem, thus demonstrating the feasibility of the overall approach.

The past decade has seen extensive research on audio classification algorithms which playa key role in multimedia applications, such as the retrieval of audio information from an audio or audiovisual database. However, the effect of background noise on the performance of classification has not been widely investigated. Motivated by the noise-suppression property of the early auditory (EA) model presented by Wang and Shamma, we seek in this thesis to further investigate this property and to develop improved algorithms for audio classification in the presence of background noise.
With respect to the limitation of the original analysis, a better yet mathematically tractable approximation approach is first proposed wherein the Gaussian cumulative distribution function is used to derive a new closed-form expression of the auditory spectrum at the output of the EA model, and to conduct relevant analysis. Considering the computational complexity of the original EA model, a simplified auditory spectrum is proposed, wherein the underlying analysis naturally leads to frequency-domain approximation for further reduction in the computational complexity. Based on this time-domain approximation, a simplified FFT-based spectrum is proposed wherein a local spectral self-normalization is implemented. An improved implementation of this spectrum is further proposed to calculate a so-called FFT-based auditory spectrum, which allows more flexibility in the extraction of noise-robust audio features.
To evaluate the performance of the above FFT-based spectra, speech/music/noise and noise/non-noise classification experiments are conducted wherein a support vector machine algorithm (SVMstruct) and a decision tree learning algorithm (C4.5) are used as the classifiers. Several features are used for the classification, including the conventional mel-frequency cepstral coefficient (MFCC) features as well as DCT-based and spectral features derived from the proposed FFT-based spectra. Compared to the conventional features, the auditory-related features show more robust performance in mismatched test cases. Test results also indicate that the performance of the proposed FFT-based auditory spectrum is slightly better than that of the original auditory spectrum, while its computational complexity is reduced by an order of magnitude.
Finally, to further explore the proposed FFT-based auditory spectrum from a practical audio classification perspective, a floating-point DSP implementation is developed and optimized on the TMS320C6713 DSP Starter Kit (DSK) from Texas Instruments.
