Abstract (sommario):
This thesis performs an investigation into issues concerning the broad area ofIdentity and Access Management, with a focus on open environments. Through literature research the issues of privacy, anonymity and access control are identified. The issue of privacy is an inherent problem due to the nature of the digital network environment. Information can be duplicated and modified regardless of the wishes and intentions ofthe owner of that information unless proper measures are taken to secure the environment. Once information is published or divulged on the network, there is very little way of controlling the subsequent usage of that information. To address this issue a model for privacy is presented that follows the user centric paradigm of meta-identity. The lack of anonymity, where security measures can be thwarted through the observation of the environment, is a concern for users and systems. By an attacker observing the communication channel and monitoring the interactions between users and systems over a long enough period of time, it is possible to infer knowledge about the users and systems. This knowledge is used to build an identity profile of potential victims to be used in subsequent attacks. To address the problem, mechanisms for providing an acceptable level of anonymity while maintaining adequate accountability (from a legal standpoint) are explored. In terms of access control, the inherent weakness of single factor authentication mechanisms is discussed. The typical mechanism is the user-name and password pair, which provides a single point of failure. By increasing the factors used in authentication, the amount of work required to compromise the system increases non-linearly. Within an open network, several aspects hinder wide scale adoption and use of multi-factor authentication schemes, such as token management and the impact on usability. The framework is developed from a Utopian point of view, with the aim of being applicable to many situations as opposed to a single specific domain. The framework incorporates multi-factor authentication over multiple paths using mobile phones and GSM networks, and explores the usefulness of such an approach. The models are in tum analysed, providing a discussion into the assumptions made and the problems faced by each model.

Abstract (sommario):
The motivation for this study argued that current information security ed- ucation systems are inadequate for educating all users of computer systems world wide in acting securely during their operations with information sys- tems. There is, therefore, a pervasive need for information security knowledge in all aspects of modern life. E-Learning 2.0 could possi- bly contribute to solving this problem, however, little or no knowledge currently exists regarding the suitability and practicality of using such systems to infer information security knowledge to learners.

Abstract (sommario):
The increasing reliance on information technology to support business processes has emphasised the need for information security mechanisms. This, however, has resulted in an ever-increasing workload in terms of security administration. Security administration encompasses the activity of ensuring the correct enforcement of access control within an organisation. Access rights and their allocation are dictated by the security policies within an organisation. As such, security administration can be seen as a policybased approach. Policy-based approaches promise to lighten the workload of security administrators. Separation of duties is one of the principles cited as a criterion when setting up these policy-based mechanisms. Different types of separation of duty policies exist. They can be categorised into policies that can be enforced at administration time, viz. static separation of duty requirements and policies that can be enforced only at execution time, viz. dynamic separation of duty requirements. This dissertation deals with the specification of both static separation of duty requirements and dynamic separation of duty requirements in role-based workflow environments. It proposes a model for the specification of separation of duty requirements, the expressions of which are based on set theory. The model focuses, furthermore, on the enforcement of static separation of duty. The enforcement of static separation of duty requirements is modelled in terms of invariant conditions. The invariant conditions specify restrictions upon the elements allowed in the sets representing access control requirements. The sets are themselves expressed as database tables within a relational database management system. Algorithms that stipulate how to verify the additions or deletions of elements within these sets can then be performed within the database management system. A prototype was developed in order to demonstrate the concepts of this model. This prototype helps demonstrate how the proposed model could function and flaunts its effectiveness.

Abstract (sommario):
The importance of information in business today has made the need to properly secure this asset evident. Information security has become a responsibility for all managers of an organization. To better support more efficient management of information security, timely information security management information should be made available to all managers. Smaller organizations face special challenges with regard to information security management and reporting due to limited resources (Ross, 2008). This dissertation discusses a Framework for Information Security Management Information (FISMI) that aims to improve the visibility and contribute to better management of information security throughout an organization by enabling the provision of summarized, comprehensive information security management information to all managers in an affordable manner.

Abstract (sommario):
To perform their business activities effectively, organizations rely heavily on the use of information (ISO/IEC TR 13335-2, 1996, p 1). Owens (1998) reiterates this by claiming that all organizations depend on information for their everyday operation and without it business will fail to operate (Owens, 1998, p 1-2). For an organization it means that if the right information is not available at the right time, it can make the difference between profit and loss or success and failure (Royds, 2000, p 2). Information is an asset and just like other important business assets within the organization, it has extreme value to an organization (BS 7799-1, 1999, p 1; Humphreys, Moses & Plate, 1998, p 8). For this reason it has become very important that business information is sufficiently protected. There are many different ways in which information can exist. Information can be printed or written on paper, stored electronically, transmitted electronically or by post, even spoken in conversation or any other way in which knowledge and ideas can be conveyed (URN 99/703, 1999, p. 2; Humphreys, Moses & Plate, 1998, p 8; URN 96/702, 1996, p 3).It is, therefore, critical to protect information, and to ensure that the security of IT (Information Technology) systems within organizations is properly managed. This requirement to protect information is even more important today, since many organizations are internally and externally connected by networks of IT systems (ISO/IEC TR 13335-2, 1996, p 1). Information security is therefore required to assist in the process of controlling and securing of information from accidental or malicious changes, deletions or unauthorized disclosure (Royds, 2000, p 2; URN 96/702, 1996, p 3). By preventing and minimizing the impact of security incidents, information security can ensure business continuity and reduce business damage (Owens, 1998, p 7). Information security in an organization can be regarded as a management opportunity and should become an integral part of the whole management activity of the organization. Obtaining commitment from management is therefore extremely important for effective information security. One way in which management can show their commitment to ensuring information security, is to adopt and enforce a security policy. A security policy ensures that people understand exactly what important role they play in securing information assets.

Abstract (sommario):
This thesis examines distributed authentication in the process of controlling computing resources. We investigate user sign-on and two of the main authentication technologies that can be used to control a resource through authentication and providing additional security services. The problems with the existing sign-on scenario are that users have too much credential information to manage and are prompted for this information too often. Single Sign-On (SSO) is a viable solution to this problem if physical procedures are introduced to minimise the risks associated with its use. The Generic Security Services API (GSS-API) provides security services in a manner in- dependent of the environment in which these security services are used, encapsulating security functionality and insulating users from changes in security technology. The un- derlying security functionality is provided by GSS-API mechanisms. We developed the Secure Remote Password GSS-API Mechanism (SRPGM) to provide a mechanism that has low infrastructure requirements, is password-based and does not require the use of long-term asymmetric keys. We provide implementations of the Java GSS-API bindings and the LIPKEY and SRPGM GSS-API mechanisms. The Secure Authentication and Security Layer (SASL) provides security to connection- based Internet protocols. After finding deficiencies in existing SASL mechanisms we de- veloped the Secure Remote Password SASL mechanism (SRP-SASL) that provides strong password-based authentication and countermeasures against known attacks, while still be- ing simple and easy to implement. We provide implementations of the Java SASL binding and several SASL mechanisms, including SRP-SASL.

Abstract (sommario):
Traditional methods of IT recruitment in tertiary institutions need to be reviewed and more modern approaches analysed. A lot of successes and failures have been reported for each type of sourcing strategy in the IT sector. Many organizations have been liquidated due to poorly planned mergers, takeovers, and total outsourcing strategic shifts. The primary objective is to review the current IT sourcing strategies in tertiary institutions and to analyse and discuss the benefits and limitations of employing permanent IT staff, contract workers or outsourced staff.

Abstract (sommario):
Outsourcing has become an attractive option for today's organisation. Since outsourcing Information Technology (IT) is a relatively new phenomenon in Australia, little research has been conducted as to IT management strategies needed when considering outsourcing. To guide management in the decision whether or not to outsource IT, the study developed and tested a decision-making model comprising the phases of intelligence, analysis and planning, strategy selection, action, and evaluation and monitoring. The significance of decision phases and tasks contained in the model was established through a survey of major Australian organisations. The sample included Australia's top 390 companies. Such organisations would be likely to have large IT installation and therefore would have greater knowledge of IT outsourcing. The model was also applied in four major case studies to contribute to the survey and to help in interpreting the survey results. Respondent experiences in making IT outsourcing decisions were discussed. The study found that the 'action' phase of IT outsourcing is the most important decision-making phase. It is largely determined by the track record and the ability of the potential vendor to provide high service levels for the client. The need for an acceptable level of service is also strongly apparent when management evaluates and monitors the outcome of IT outsourcing. In recognition of the importance of the action phase the study presented an expanded model. It shows an expanded representation of the activities, presented in life eyrie form, related to selecting a suitable vendor and entering into an outsourcing contract. The study concluded that the proposed model was sufficiently comprehensive and structured to be a useful guide for IS outsourcing decision making. It enabled decision makers to consider complex, wide ranging and interrelated decision criteria concerning IS outsourcing for their particular circumstances and needs. Knowledge of the above findings should provide the following benefits: *The identification and description of phases, tasks and subtasks provides a checklist of what needs to be taken into account during IT outsourcing decision-making; *The identification of key phases, tasks and sub tasks will help management and others to focus on critical areas that need to be managed well in order for IT outsourcing to be successful; *The identification of the action phase as the most important phase enables management attention to be particularly focussed; *The framework can be used on a 'as needed' basis thereby making it useful for different outsourcing decision scenarios and situations. The study concludes with the research limitations and suggestions for future research.

Testo completo
Abstract (sommario):
La stéganographie est l’art de la dissimulation de l’information secrète dans un médium donné (cover) de sorte que le médium résultant (stégo) soit quasiment identique au médium cover. De nos jours, avec la mondialisation des échanges (Internet, messagerie et commerce électronique), s’appuyant sur des médiums divers (son, image, vidéo), la stéganographie moderne a pris de l’ampleur. Dans ce manuscrit, nous avons étudié les méthodes de stéganographie LSB adaptatives, dans les domaines spatial et fréquentiel (DCT, et DWT), permettant de cacher le maximum d’information utile dans une image cover, de sorte que l’existence du message secret dans l’image stégo soit imperceptible et pratiquement indétectable. La sécurité du contenu du message, dans le cas de sa détection par un adversaire, n’est pas vraiment assurée par les méthodes proposées dans la littérature. Afin de résoudre cette question, nous avons adapté et implémenté deux méthodes (connues) de stéganographie LSB adaptatives, en ajoutant un système chaotique robuste permettant une insertion quasi-chaotique des bits du message secret. Le système chaotique proposé consiste en un générateur de séquences chaotiques robustes fournissant les clés dynamiques d’une carte Cat 2-D chaotique modifiée. La stéganalyse universelle (classification) des méthodes de stéganographie développées est étudiée. A ce sujet, nous avons utilisé l’analyse discriminante linéaire de Fisher comme classifieur des vecteurs caractéristiques de Farid, Shi et Wang. Ce choix est basé sur la large variété de vecteurs caractéristiques testés qui fournissent une information sur les propriétés de l’image avant et après l’insertion du message. Une analyse des performances des trois méthodes de stéganalyse développées, appliquées sur des images stégo produites par les deux méthodes de stéganographie LSB adaptatives proposées, est réalisée. L’évaluation des résultats de la classification est réalisée par les paramètres: sensibilité, spécificité, précision et coefficient Kappa
Steganography is the art of the dissimulation of a secret message in a cover medium such that the resultant medium (stego) is almost identical to the cover medium. Nowadays, with the globalization of the exchanges (Internet, messaging and e-commerce), using diverse mediums (sound, embellish with images, video), modern steganography is widely expanded. In this manuscript, we studied adaptive LSB methods of stéganography in spatial domain and frequency domain (DCT, and DWT), allowing of hiding the maximum of useful information in a cover image, such that the existence of the secret message in the stégo image is imperceptible and practically undetectable. Security of the message contents, in the case of its detection by an opponent, is not really insured by the methods proposed in the literature. To solve this question, we adapted and implemented two (known) methods of adaptive stéganographie LSB, by adding a strong chaotic system allowing a quasi-chaotic insertion of the bits of the secret message. The proposed chaotic system consists of a generator of strong chaotic sequences, supplying the dynamic keys of a modified chaotic 2D Cat map. Universal steganalysis (classification) of the developed methods of stéganography, is studied. On this question, we used the linear discriminating analysis of Fisher as classifier of the characteristic vectors of Farid, Shi and Wang. This choice is based on the wide variety of tested characteristic vectors that give an information about the properties of the image before and after message insertion. An analysis of the performances of three developed methods of steganalysis, applied to the produced stego images by the proposed adaptive methods of stéganography, is realized. Performance evaluation of the classification is realized by using the parameters: sensibility, specificity, precision and coefficient Kappa

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: in Information Technology in the Faculty of Informatics and Design at the Cape Peninsula University of Technology Supervisor: Dr Ephias Ruhode Cape Town campus December 2013
The use of ICTs such as computers, electronic databases and other technologies have been in use for a number of years within the public sector to organise, manage and disseminate information to the public as well as to facilitate day-to-day communication in government offices. In this context, the value of the use of ICTs has been to assist and streamline government operations. The technological development in South Africa has opened up the possibilities of the use of ICTs in the democratic and governance process. E-democracy has been defined as a tool for abandoning the representative system for one with more direct citizen engagement. This study sets out to explore the challenges of the current electoral process, and also determine the factors that could influence the adoption and diffusion of e-voting technologies within the South African context. Literature has shown that countries such as Brazil and India have successfully implemented electronic voting systems and other countries are at various piloting stages to address many challenges and problems associated with manual paper based system such as costs of physical ballot paper and other overheads, electoral delays, distribution of electoral materials, and general lack of confidence in the electoral process. It is in this context that the study also seeks to determine whether the South African electoral management body can leverage on the opportunities that e-voting presents. However, with all the benefits that e-voting presents, there are countries such Germany, the Netherlands etc. that have tried and tested e-voting systems and decided to abandon these system to go back to the manual paper ballot voting systems because of various reasons ranging from cost, security and verifiability. This research is exploratory in nature and adopts qualitative research approach and it is within the interpretivism paradigm. Survey and interview strategies were used to collect data. A purposive sampling method was used to select the participants for the survey. To gain an understanding of the views of voters and electoral management body (IEC) about the current electoral process and e-voting technologies, literature was explored, a questionnaire was distributed online to voters and an in-depth semi-structured interview was conducted with the IEC. The study targeted voters who had access to the internet since the survey questionnaire was distributed online. The analysis is based on thematic analysis and diffusion of innovation (DoI) theory was also used to provide an analytical framework for the study. Through this framework the aims and objectives of the study were conceptualized around three constructs from the theory (relative advantage, compatibility and complexity). The findings of the study revealed that the three constructs from the DoI framework are important factors that may influence the adoption process of e-voting technologies. The findings also revealed other factors such as availability of ICT enable infrastructure and resources, digital divide, trust in technology, awareness of the technology and environment could that also influence the adoption process. The contributions of this research are anticipated to be a better understanding of the adoption of e-voting technologies in South Africa. For the electoral management bodies, the contribution of this research is that the research to some extent portrays factors that could influence the adoption of e-voting technologies in South Africa. Therefore, findings such as availability of ICT infrastructure and accessibility of these infrastructures should be taken into consideration before introducing e-voting technologies. Keywords: DoI (diffusion of Innovation), e-voting (electronic voting) technologies, E-governance, e-participation.

Thesis (LLM)--Stellenbosch University, 2004
ENGLISH ABSTRACT: This thesis deals with the criminal liability of Internet providers. The focus is on Germany, but the analysis is put in a wider, comparative context. This is done with reference to South Africa, as well as Europe and the American system. This thesis demonstrates and discusses the existing legal norms to regulate Internet provider liability for illegal content on the Internet and the international efforts to deal with this issue. In the introduction it is shown how the Internet has given rise to a new form of global communication and the accompanying legal problems. This is followed by an examination of the different functions Internet providers have. A survey of some of the important crimes affecting the Internet and also some Internet-specific offences put the more general issue of liability in a more specific context. Traditional and new forms of crimes are discussed. This section is followed by an analysis of Internet provider liability under German criminal law and Germany's Teleservices Act. From an international criminal law perspective some international instruments, like the Cybercrime Convention of the Council of Europe, is discussed. National legislation, especially in the context of the European Union, must always be put in the proper regional and international context. The thesis concludes with some thoughts on alternative, or perhaps complementary, methods to fight illegal and criminal conduct on the Internet. This is done not as a critique of the responses to Internet crime, but rather to strengthen the many hands trying to reduce Internet crime.
AFRIKAANSE OPSOMMING: Hierdie tesis handeloor die strafregtelike aanspreekliheid van Internet diensverskaffers. Die fokus val op Duitsland, maar die analise word ook geplaas in 'n wyer, vergelykende konteks. Dit word gedoen met verwysing na Suid-Afrika, sowel as Europa en die VSA. Die tesis demonstreer en bespreek die bestaande regsnorme wat Internet diensverskaffers reguleer met spesifieke verwysing na aanspreeklikheid vir onwettige inhoud op die Internet en internasionale pogings om hierdie probleem aan te spreek. Ter inleiding word daar aangetoon hoe die Internet aanleiding gee tot nuwe vorme van globale kommunikasie en die regsprobleme wat dit tot gevolg het. Dit word gevolg deur 'n ondersoek na die verskillende funksies van Internet verskaffers. 'n Ontleding en bespreking van Internet-spesifieke misdrywe plaas die meer algemene vraagstuk in 'n meer gefokusde konteks. Tradisionele en nuwe vorme van misdaad word bespreek. Hierdie afdeling word gevolg deur 'n ontleding van Internet diensverskaffer aanspreeklikheid ingevolge Duitse reg en die Duitse wetgewing op die terrein van telediens. Uit 'n internasionale strafreg oogpunt word sekere internasionale instrumente, soos die Cybercrime Convention van die Raad van Europa, bespreek. Nasionale wetgewing, veral in die konteks van die Europese Unie, word ook in die relevante regionale en internasionale konteks geplaas. Die tesis word afgesluit met sekere gedagtes oor alternatiewe, of moontlik komplimentêre, metodes in die stryd teen Internet-kriminaliteit. Dit moet nie gesien word as kritiek op die huidige stand van sake nie, maar eerder as 'n poging om die talle rolspelers in die stryd teen Internet misdaad se hande te sterk.

Abstract (sommario):
The work presented in this thesis comprises a proposed robust diffusion weighted magnetic resonance imaging (DW-MRI) pipeline, each chapter detailing a step designed to ultimately transform raw DW-MRI data into segmented bundles of coherent fibre ready for more complex analysis or manipulation. In addition to this pipeline we will also demonstrate, where appropriate, ways in which each step could be optimized for the maxillofacial region, setting the groundwork for a wider maxillofacial modelling project intended to aid surgical planning. Our contribution begins with RESDORE, an algorithm designed to automatically identify corrupt DW-MRI signal elements. While slower than the closest alternative, RESDORE is also far more robust to localised changes in SNR and pervasive image corruptions. The second step in the pipeline concerns the retrieval of accurate fibre orientation distribution functions (fODFs) from the DW-MRI signal. Chapter 4 comprises a simulation study exploring the application of spherical deconvolution methods to `generic' fibre; finding that the commonly used constrained spherical harmonic deconvolution (CSHD) is extremely sensitive to calibration but, if handled correctly, might be able to resolve muscle fODFs in vivo. Building upon this information, Chapter 5 conducts further simulations and in vivo image experimentation demonstrating that this is indeed the case, allowing us to demonstrate, for the first time, anatomically plausible reconstructions of several maxillofacial muscles. To complete the proposed pipeline, Chapter 6 then introduces a method for segmenting whole volume streamline tractographies into anatomically valid bundles. In addition to providing an accurate segmentation, this shape-based method does not require computationally expensive inter-streamline comparisons employed by other approaches, allowing the algorithm to scale linearly with respect to the number of streamlines within the dataset. This is not often true for comparison based methods which in the best case scale in higher linear time but more often by O(N2) complexity.

Abstract (sommario):
De nos jours, les smartphones et les tablettes génèrent, reçoivent, mémorisent et transfèrent vers des serveurs une grande quantité de données en proposant des services aux utilisateurs via des applications mobiles facilement téléchargeables et installables. Le grand nombre de capteurs intégrés dans un smartphone lui permet de collecter de façon continue des informations très précise sur l'utilisateur et son environnement. Cette importante quantité de données privées et professionnelles devient difficile à superviser.L'approche «Privacy by Design», qui inclut sept principes, propose d'intégrer la notion du respect des données privées dès la phase de la conception d’un traitement informatique. En Europe, la directive européenne sur la protection des données privées (Directive 95/46/EC) intègre des notions du «Privacy by Design». La nouvelle loi européenne unifiée (General Data Protection Régulation) renforce la protection et le respect des données privées en prenant en compte les nouvelles technologies et confère au concept de «Privacy by Design» le rang d’une obligation légale dans le monde des services et des applications mobiles.L’objectif de cette thèse est de proposer des solutions pour améliorer la transparence des utilisations des données personnelles mobiles, la visibilité sur les systèmes informatiques, le consentement et la sécurité pour finalement rendre les applications et les systèmes mobiles plus conforme au «Privacy by (re)Design»
Nowadays, smartphones and smart tablets generate, receive, store and transfer substantial quantities of data, providing services for all possible user needs with easily installable programs, also known as mobile applications. A number of sensors integrated into smartphones allow the devices to collect very precise information about the owner and his environment at any time. The important flow of personal and business data becomes hard to manage.The “Privacy by Design” approach with 7 privacy principles states privacy can be integrated into any system from the software design stage. In Europe, the Data Protection Directive (Directive 95/46/EC) includes “Privacy by Design” principles. The new General Data Protection Regulation enforces privacy protection in the European Union, taking into account modern technologies such as mobile systems and making “Privacy by Design” not only a benefit for users, but also a legal obligation for system designers and developers.The goal of this thesis is to propose pattern-oriented solutions to cope with mobile privacy problems, such as lack of transparency, lack of consent, poor security and disregard for purpose limitation, thus giving mobile systems more Privacy by (re) Design

Lewis, Tony. "Electronic data interchange in the construction industry". Thesis, Loughborough University, 1998. https://dspace.lboro.ac.uk/2134/11183.

Abstract (sommario):
The aim of this research is to improve the efficiency of the construction process through the application of electronic data interchange (EDI). This thesis describes the development and application of EDI messages. The messages described are targeted to provide a means for transferring construction specific information during the construction process. The definition of electronic data interchange and its technical issues are first described. The nature of EDI, replacing paper based communication with electronic messages, impacts on the way in which business is conducted, and also has far reaching legal implications due to the reliance of many legal systems on paper documents and signatures. The business and legal implications are therefore discussed in detail. The application of EDI in the construction industry is investigated by means of a literature review. This work is furthered by a longitudinal study of the construction industry's application of EDI, which consisted of two surveys at a five year interval. A model of the information flows within the traditional construction process is developed to assist in the identification of information flows suitable for EDI. A methodology for message development was produced. The methodology was then applied to develop a description data model that could be utilised in the existing bill of quantity and trading cycle messages. The bill of quantity message set was at a stage ready for trial. To determine the issues related to implementation specifically in the construction industry a trial implementation of this message set was undertaken. The official implementation undertaken by EDICON is described. Software was also developed to undertake the trial. This software was tested and proved the message set developed was suitable for the transfer of bill of quantity related information during a construction project. The factors causing the failure of the implementation of the bill of quantities message set are discussed. A number of these factors are considered valid for all construction project information flows. Finally, the use of shared project models to re-engineer construction information tasks is recommended as a means of achieving significant benefit from electronic data exchange in the construction process.

Testo completo
Abstract (sommario):
The synthesis of imperative programs for hierarchical, algebraically specified abstract data types is investigated. Two aspects of the synthesis are considered: the choice of data structures for efficient implementation, and the synthesis of linked implementations for the class of ADTs which insert and access data without explicit key. The methodology is based on an analysis of the algebraic semantics of the ADT. Operators are partitioned according to the behaviour of their corresponding operations in the initial algebra. A family of relations, the storage relations of an ADT, Is defined. They depend only on the operator partition and reflect an observational view of the ADT. The storage relations are extended to storage graphs: directed graphs with a subset of nodes designated for efficient access. The data structures in our imperative language are chosen according to properties of the storage relations and storage graphs. Linked implementations are synthesised in a stepwise manner by implementing the given ADT first by its storage graphs, and then by linked data structures in the imperative language. Some circumstances under which the resulting programs have constant time complexity are discussed.

Abstract (sommario):
The aim of this work was to investigate signal processing and analysis techniques for Ground Penetrating Radar (GPR) and its use in civil engineering and construction industry. GPR is the general term applied to techniques which employ radio waves, typically in the Mega Hertz and Giga Hertz range, to map structures and features buried in the ground or in manmade structures. GPR measurements can suffer from large amount of noise. This is primarily caused by interference from other radio-wave-emitting devices (e.g., cell phones, radios, etc.) that are present in the surrounding area of the GPR system during data collection. In addition to noise, presence of clutter – reflections from other non-target objects buried underground in the vicinity of the target can make GPR measurement difficult to understand and interpret, even for the skilled human, GPR analysts. This thesis is concerned with the improvements and processes that can be applied to GPR data in order to enhance target detection and characterisation process particularly with multivariate signal processing techniques. Those primarily include Principal Component Analysis (PCA) and Independent Component Analysis (ICA). Both techniques have been investigated, implemented and compared regarding their abilities to separate the target originating signals from the noise and clutter type signals present in the data. Combination of PCA and ICA (SVDPICA) and two-dimensional PCA (2DPCA) are the specific approaches adopted and further developed in this work. Ability of those methods to reduce the amount of clutter and unwanted signals present in GPR data have been investigated and reported in this thesis, suggesting that their use in automated analysis of GPR images is a possibility. Further analysis carried out in this work concentrated on analysing the performance of developed multivariate signal processing techniques and at the same time investigating the possibility of identifying and characterising the features of interest in pre-processed GPR images. The driving idea behind this part of work was to extract the resonant modes present in the individual traces of each GPR image and to use properties of those poles to characterise target. Three related but different methods have been implemented and applied in this work – Extended Prony, Linear Prediction Singular Value Decomposition and Matrix Pencil methods. In addition to these approaches, PCA technique has been used to reduce dimensionality of extracted traces and to compare signals measured in various experimental setups. Performance analysis shows that Matrix Pencil offers the best results.

Abstract (sommario):
An investigation is presented into an interrupt-generating object model which is designed to reduce the effort of programming distributed memory multicomputer networks. The object model is aimed at the natural modelling of problem domains in which a number of concurrent entities interrupt one another as they lay claim to shared resources. The proposed computational model provides for the safe encapsulation of shared data, and incorporates inherent arbitration for simultaneous access to the data. It supplies a predicate triggering mechanism for use in conditional synchronization and as an alternative mechanism to polling. Linguistic support for the proposal requires a novel form of control structure which is able to interface sensibly with interrupt-generating active data objects. The thesis presents the proposal as an elemental language structure, with axiomatic guarantees which enforce safety properties and aid in program proving. The established theory of CSP is used to reason about the object model and its interface. An overview is presented of a programming language called HUL, whose semantics reflect the proposed computational model. Using the syntax of HUL, the application of the interrupt-generating active data object is illustrated. A range of standard concurrent problems is presented to demonstrate the properties of the interrupt-generating computational model. Furthermore, the thesis discusses implementation considerations which enable the model to be mapped precisely onto multicomputer networks, and which sustain the abstract programming level provided by the interrupt-generating active data object in the wider programming structures of HUL.

Thesis (Diploma (Electrical Engineering))--Cape Technikon, 1986.
This thesis describes the implementation of a general-purpose, microprocessor-based Data Logger. The Hardware allows analog data acquisition from one to thirty two channels with 12 bit resolution and at a data throughput of up to 2KHz. The data is logged directly to a Buffer memory and from there, at the end of each 109, it is dumped to an integral cassette data recorder. The recorded data can be transfered from the logger to a desk-top computer, via the IEEE 488 port, for further processing and display. All log parameters are user selectable by means of menu prompted keyboard entry and a Real-Time clock (RTC) provides date and time information automatically.
