Abstract:
In recent years, with only small fractions of modern processors now accessible in a single cycle, computer architects constantly fight against propagation issues across the die. Unfortunately this trend continues to shift inward, and now the even most internal features of the pipeline are designed around communication, not computation. To address the inward creep of this constraint, this work focuses on the characterization of communication within the pipeline itself, architectural techniques to avoid it when possible, and layout co-design for early detection of problems. I present work in creating a novel detection tool for common case operand movement which can rapidly characterize an applications dataflow patterns. The results produced are suitable for exploitation as a small number of patterns can describe a significant portion of modern applications. Work on dynamic dependence collapsing takes the observations from the pattern results and shows how certain groups of operations can be dynamically grouped, avoiding unnecessary communication between individual instructions. This technique also amplifies the efficiency of pipeline data structures such as the reorder buffer, increasing both IPC and frequency. I also identify the same sets of collapsible instructions at compile time, producing the same benefits with minimal hardware complexity. This technique is also done in a backward compatible manner as the groups are exposed by simple reordering of the binarys instructions. I present aggressive pipelining approaches for these resources which avoids the critical timing often presumed necessary in aggressive superscalar processors. As these structures are designed for the worst case, pipelining them can produce greater frequency benefit than IPC loss. I also use the observation that the dynamic issue order for instructions in aggressive superscalar processors is predictable. Thus, a hardware mechanism is introduced for caching the wakeup order for groups of instructions efficiently. These wakeup vectors are then used to speculatively schedule instructions, avoiding the dynamic scheduling when it is not necessary. Finally, I present a novel approach to fast and high-quality chip layout. By allowing architects to quickly evaluate what if scenarios during early high-level design, chip designs are less likely to encounter implementation problems later in the process.

Abstract:
There is a high rate of information system implementation failures attributed to the lack of alignment between business and information technology strategy. Although enterprise architecture (EA) is a means to correct alignment problems and executives highly rate the importance of EA, it is still not used in most organizations today. Current literature only gave anecdotal reasons why EA was not more widely adopted. This study explored the problem of EA underutilization by understanding how organizational executives value EA. This research used the grounded theory methodology to obtain the EA perspectives of organizational executives responsible for EA. Seventeen executives were selected using theoretical sampling and interviewed using a semi-structured interview approach. The interview data was recorded and coded, and interviewing continued until theoretical saturation was reached. The executives identified four distinct meanings of EA, i.e., business and IT alignment, a holistic representation of the enterprise, a planned vision of the future, and a process, methodology, or framework enhancing enterprise decision making. In addition, they identified 16 unique benefits that EA provided. Depending on the meaning of EA, it was possible to predict what benefits they expected. For example, if the meaning of EA was a holistic representation of the enterprise, then the benefits of increase operational effectiveness, planning, product selection, and speak a common language were expected. However, regardless of which of the four meanings of EA was selected, executives expected EA to facilitate the alignment of business and IT, the decision making process, and the simplification of system and architecture management. Based on the findings, an analytic story and a theoretical model were produced. The model depicted the influencers on what meaning an executive chose and, based on the meaning, the expected benefits of EA. The understanding of executives' perceptions of EA is critical because they are the most influential leaders within organizations. Without their understanding, it becomes less likely that EA initiatives would meet organizational expectations and have favorable outcomes. Furthermore, it is hoped that this study shapes future EA initiatives so that they become more aligned with the views of the executives who are responsible for them.

Abstract:
A evolução constante dos processadores está aumentando cada vez o overhead dos acessos à memória. Tentando evitar este problema, os desenvolvedores de processadores utilizam diversas técnicas, entre elas, o emprego de memórias cache na hierarquia de memórias dos computadores. As memórias cache, por outro lado, não conseguem suprir totalmente as suas necessidades, sendo interessante alguma técnica que tornasse possível aproveitar melhor a memória cache. Para resolver este problema, autores propõem a utilização de técnicas de computação reconfigurável. Este trabalho analisa um trabalho na área de reconfiguração na associatividade de memórias cache, e propõe melhorias nele para uma melhor utilização de seus recursos, apresentando resultados práticos de simulações realizadas com diversas organizações de cache.
With the constant evolution of processors architecture, its getting even bigger the overhead generated with memory access. Trying to avoid this problem, some processors developers are using several techniques to improve the performance, as the use of cache memories. By the otherside, cache memories cannot supply all their needs, thats why its important some new technique that could use better the cache memory. Working on this problem, some authors are using reconfigurable computing to improve the cache memorys performance. This work analyses the reconfiguration of the cache memory associativity algorithm, and propose some improvements on this algorithm to better use its resources, showing some practical results from simulations with several cache organizations.

Abstract:
Sistemas Ciberfísicos (SCF) são sistemas onde existe uma união entre computação e física. Os SCF serão utilizados nas mais diversas áreas, formando uma nova era de produtos e estarão em qualquer lugar, sendo utilizados por qualquer um e para qualquer tarefa. Aplicações para SCF incluem sistemas e dispositivos médicos altamente confiáveis, controle de tráfego e segurança, sistemas automotivos avançados, controle de processos, conservação de energia, controle ambiental, aviação, instrumentação, controle de infra estrutura crítica, sistemas de defesa, fabricação e estruturas inteligentes. O cenário de sistemas ciberfísicos (SCF) exigirá dos processadores de sistemas embarcados melhorias em características além de processamento de I/O, consumo de energia e comunicação, ou seja, as futuras arquiteturas de processadores deverão possuir também características de segurança, tolerância à falhas e flexibilidade arquitetural para adequação aos diversos cenários alvo de SCF. Neste contexto, nesta tese de doutorado, idealizou-se uma arquitetura modular multicore (AMM), voltada à SCF, composta por processadores multicore, hardware dedicado ou ambos. Dessa maneira, propõe-se um processador para a arquitetura AMM e avalia-se seu correto funcionamento por meio de simulações no software Modelsim e ferramentas de simulação de circuitos integrados. Apresenta-se um protótipo para uma primeira versão da arquitetura AMM e detalham-se alguns programas especificamente escritos para comprovar as principais características da arquitetura. Na tese, apresentam-se testes funcionais em FPGA para o processador base do protótipo AMM, dados de utilização do protótipo do processador da arquitetura AMM em FPGA e um protótipo do processador da AMM em silício. Analisa-se o protótipo da arquitetura AMM com aplicações criticas e de uso em SCF, tais como: segurança, redundância, e tolerância a falhas; as quais permitem concluir que os processadores futuros de SCF devem ter essas características. A tese mostra que esses quesitos podem ser incluídos em sistemas embarcados com características multicore dedicados a aplicações e necessidades de sistemas SCF.
Cyber-physical Systems (CPS) are systems where there is an union between computing and physics. The CPS will be used in several areas, forming a new era of systems or devices and could be anywhere, being used by anyone and anything. Applications for CPS include highly reliable medical systems and devices, traffic control and security, advanced automotive, process control, energy conservation, environmental control, aviation, instrumentation, control of critical infrastructure, defense systems, manufacturing, and smart structures. So, CPS scenario needs requirements design of embedded systems, composed by processors with new features in addition to I/O processing, power consumption, and communication. Then, the future of processor architectures should also have security, fault tolerance, architectural adaptation and flexibility to various and different scenarios. In this context, in this thesis, it is proposed a modular architecture to multicore processor (AMM) to use in the CPS. It is composed by multicore processors, dedicated hardware or both. Thus, in this thesis, we have proposed one processor architecture and we have done verification based on simulations using Modelsim software and simulation tools for integrated circuits, and we have running applications programs to demonstrate the main features of the AMM architecture. We also show a prototype of AMM using FPGA as well as implementation data such as FPGA usage and resources in silicon area. It is also presented an ASIC prototype of AMM core. The prototype architecture of the AMM was analyzed with critical applications which are used in CPS, such as security, redundancy and fault tolerance, and these tests suggest that the future CPS processors must have those characteristics. Thus, the thesis shows that these aspects can be included in embedded systems with dedicated features to multicore applications and systems used in CPS.

(1996) The role of usability in the organizational standards setting process. International Journal of Human-Computer Studies, 45(2), 243-258. ABSTRACT: The rapid introduction of microcomputers into organizations throughout the last decade gave new importance to the analysis of how technology impacts organizations. In particular, research on usability has sought to become central to the design and selection of technology for large organizations. However, definitions and methods are not yet standardized. Data gathered from semi-structured interviews of three MIS managers and 125 end-users in three organizations suggest that differences in emphasis on, and definition of usability can exist between these two groups. Usability was not a central concern to managers when evaluating end-user software packages considered for adoption as the organizational standard, though it appeared to be so for end-users. Moreover, managers tended to consider and evaluate usability based only on features contained in the user interface, whereas end-users often cited contextual factors such as task and environmental considerations. Implications for technology assessment and future research into organizational impact of I.T. are presented.

Abstract:

This dissertation aim is to investigate the application of higher-ordered feedback architectures, as a control system for an autonomous robot, on delayed response task problems in the area of evolutionary robotics. For the two architectures of interest a theoretical and practical experiment study is conducted to elaborate how these architectures cope with the road-sign problem, and extended versions of the same. In the theoretical study conducted in this dissertation focus is on the features of the architectures, how they behave and act in different kinds of road-sign problem environments in earlier work. Based on this study two problem environments are chosen for practical experiments. The two experiments that are tested are the three-way and multiple stimuli road-sign problems. Both architectures seams to be cope with the three-way road-sign problem. Although, both architectures are shown to have difficulties solving the multiple stimuli road-sign problem with the current experimental setting used.

This work leads to two insights in the way these architectures cope with and behave in the three-way road-sign problem environment and delayed response tasks. The robot seams to learn to explicitly relate its actions to the different stimuli settings that it is exposed to. Firstly, both architectures forms higher abstracted representations of the inputs from the environment. These representations are used to guide the robots actions in the environment in those situations were the raw input not was enough to do the correct actions. Secondly, it seams to be enough to have two internal representations of stimuli setting and offloading some stimuli settings, relying on the raw input from the environment, to solve the three-way road-sign problem.

The dissertation works as an overview for new researchers on the area and also as take-off for the direction to which further investigations should be conducted of using higher-ordered feedback architectures.

Abstract:
A descoberta do algoritmo de Shor, para a fatoração de inteiros em tempo polinomial, motivou esforços rumo a implementação de um computador quântico. Ele é capaz de quebrar os principais criptossistemas de chave pública usados hoje (RSA e baseados em curvas elípticas). Estes fornecem diversos serviços de segurança, tais como confidencialidade e integridade dos dados e autenticação da fonte, além de possibilitar a distribuição de uma chave simétrica de sessão. Para quebrar estes criptossistemas, um computador quântico grande (2000 qubits) é necessário. Todavia, alternativas começaram a ser investigadas. As primeiras respostas vieram da própria mecânica quântica. Apesar das propriedades interessantes encontradas na criptografia quântica, um criptossistema completo parece inatingível, principalmente devido as assinaturas digitais, essenciais para a autenticação. Foram então propostos criptossitemas baseadas em problemas puramente clássicos que (acredita-se) não são tratáveis por computadores quânticos, que são chamadas de pós-quânticas. Estes sistemas ainda sofrem da falta de praticidade, seja devido ao tamanho das chaves ou ao tempo de processamento. Dentre os criptossistemas pós-quânticos, destacam-se o McEliece e o Niederreiter. Por si só, nenhum deles prevê assinaturas digitais, no entanto, as assinaturas CFS foram propostas, complementandos. Ainda que computadores quânticos de propósito geral estejam longe de nossa realidade, é possível imaginar um circuito quântico pequeno e dedicado. A melhoria trazida por ele seria a diferença necessária para tornar essas assinaturas práticas em um cenário legitimamente pós-quântico. Neste trabalho, uma arquitetura híbrida quântica/clássica é proposta para acelerar algoritmos criptográficos pós-quânticos. Dois coprocessadores quânticos, implementando a busca de Grover, são propostos: um para auxiliar o processo de decodificação de códigos de Goppa, no contexto do criptossistema McEliece; outro para auxiliar na busca por síndromes decodificáveis, no contexto das assinaturas CFS. Os resultados mostram que em alguns casos, o uso de um coprocessador quântico permite ganhos de até 99; 7% no tamanho da chave e até 76; 2% em tempo de processamento. Por se tratar de um circuito específico, realizando uma função bem específica, é possível manter um tamanho compacto (300 qubits, dependendo do que é acelerado), mostrando adicionalmente que, caso computadores quânticos venham a existir, eles viabilizarão os criptossistemas pós-quânticos antes de quebrar os criptossistemas pré-quânticos. Adicionalmente, algumas tecnologias de implementação de computadores quânticos são estudadas, com especial enfoque na óptica linear e nas tecnologias baseadas em silício. Este estudo busca avaliar a viabilidade destas tecnologias como potenciais candidatas à construção de um computador quântico completo e de caráter pessoal.
The discovery of the Shor algorithm, which allows polynomial time factoring of integers, motivated efforts towards the implementation of a quantum computer. It is capable of breaking the main current public key cryptosystems used today (RSA and those based on elliptic curves). Those provide a set of security services, such as data confidentiality and integrity and source authentication, and also the distribution of a symmetric session key. To break those cryptosystem, a large quantum computer (2000 qubits) is needed. Nevertheless, cryptographers have started to look for alternatives. Some of which came from quantum mechanics itself. Despite some interesting properties found on quantum cryptography, a complete cryptosystem seems intangible, specially because of digital signatures, necessary to achieve authentication. Cryptosystems based on purely classical problems which are (believed) not treatable by quantum computers, called post-quantum, have them been proposed. Those systems still lacks of practicality, either because of the key size or the processing time. Among those post-quantum cryptosystems, specially the code based ones, the highlights are the McEliece and the Niederreiter cryptosystems. Per se, none of these provides digital signatures, but, the CFS signatures have been proposed, as a complement to them. Even if general purpose quantum computers are still far from our reality, it is possible to imagine a small dedicated quantum circuit. The benefits brought by it could make the deference to allow those signatures, in a truly post-quantum scenario. In this work, a quantum/classical hybrid architecture is proposed to accelerate post-quantum cryptographic algorithms. Two quantum coprocessors, implementing the Grover search, are proposed: one to assist the decoding process of Goppa codes, in the context of the McEliece and Niederreiter cryptosystems; another to assist the search for decodable syndromes, in the context of the CFS digital signatures. The results show that, for some cases, the use of the quantum coprocessor allows up to 99; 7% reduction in the key size and up to 76; 2% acceleration in the processing time. As a specific circuit, dealing with a well defined function, it is possible to keep a small size (300 qubits), depending on what is accelerated), showing that, if quantum computers come to existence, they will make post-quantum cryptosystems practical before breaking the current cryptosystems. Additionally, some implementation technologies of quantum computers are studied, in particular linear optics and silicon based technologies. This study aims to evaluate the feasibility of those technologies as potential candidates to the construction of a complete and personal quantum computer.

Abstract:
Com o crescimento exponencial do volume de dados estruturados e não estruturados (Big Data) em sistemas de armazenamento corporativos, aliado à também crescente demanda por preservação de tais dados devido a regulamentações e auditorias, surge o problema da preservação a longo prazo de Big Data, e mais especificamente o de como estender sistemas existentes ao longo do tempo. Pesquisas recentes contemplam arquiteturas de preservação de dados estruturados ou de arquivamento a curto prazo de Big Data, porém carecem de um modelo para arquiteturas que suportem a preservação a longo prazo de Big Data com elasticidade. Na presente tese, propõe-se uma arquitetura para o arquivamento, preservação a longo prazo e recuperação de Big Data com elasticidade. Um método de criação de arquiteturas de referência foi seguido e obteve-se como resultado uma arquitetura de preservação a longo prazo que é reprodutível e capaz de adaptar-se a uma demanda crescente, recebendo Big Data de fontes heterogêneas continuamente. A arquitetura é compatível com computação em nuvem e foi testada com diversas mídias de armazenamento, como mídias magnéticas, nuvem e de estado sólido. É feito também um comparativo entre a arquitetura desenvolvida e outras arquiteturas disponíveis.
With the exponential growth in the volume of structured and unstructured data (Big Data) in enterprise storage systems, along with the also increasing demand for preservation of such data due to regulations and audits, there arises the problem of long-term preservation of Big Data, and more specifically of how to extend existing systems with time. Recent research projects encompass architectures for the preservation of structured data or short term archiving of Big Data, however they lack a model for architectures that support long-term preservation of Big Data with elasticity. In the present thesis, we propose an architecture for the archiving, longterm preservation and retrieval of Big Data with elasticity. A method for creating reference architectures was followed and as a result a reproducible long-term preservation architecture was obtained, which is capable of adapting to a growing demand receiving Big Data continuously. The architecture is compatible with cloud computing and was tested against several storage media, such as magnetic media, cloud and solid state.

Abstract:
Today’s enterprises are operating in a highly complex environment with rapid disruptions from different areas such as technology, regulations or market, all of them capable of bringing the entire industry upside down. And many large organizations are adopting agile software development methods as part of their continuous push towards higher flexibility and shorter lead times. Agility, however, introduces challenges and problems for the engineering of enterprises, yet few reports on organizational alignment in this regard are available in the literature. This problem of alignment between business/operations and IT has been around for as long as computers have been introduced to the work offices and is still today an important issue for enterprises of any kind. This thesis, therefore, tries to investigate the lack of insight or fragmented knowledge regarding organizational design or architecture of modern enterprises in both academia and industry. The purpose of this thesis is to explicate the challenges and recommendations found in research papers, industrial whitepapers and interviews in order to propose guidelines for achieving better alignment. The goal of this thesis is to provide an inventory of available researches in the area of Business and IT Alignment (BITA) and organizational science in order to help suggest a basis for future research. For this purpose, a Design Science Research (DSR) strategy has been followed in combination with a literature review accompanied by two rounds of interviews as a means for data collection and evaluation. The artefacts resulting from this thesis take the form of fifteen guidelines extracted using coding analysis from the literature review and a first round of interviews at a major Swedish vehicle manufacturing enterprise. The guidelines were subsequently evaluated in a second round of interview with an industry expert reviewing the correctness and usefulness of the guidelines. The results of the evaluation proved that guidelines were useful for both the academia and industry experts. Hence, enabling the author to claim that a tentative proposition has been achieved.
Dagens företag arbetar i en mycket komplex miljö med snabba störningar från olika områden som teknik, regler eller marknader, som alla kan vända hela branschen upp och ner. Och många stora organisationer använder sig av agila programvaruutvecklingsmetoder som en del av deras kontinuerliga tryck mot högre flexibilitet och kortare ledtider. Agilitet eller snabbfothet medför emellertid utmaningar och problem för konstruktion av organisationer, men få rapporter om organisatorisk anpassning i detta avseende finns tillgängliga i litteraturen. Detta problem med anpassningen mellan verksamhet och IT har funnits så länge datorer har introducerats på arbetsplatserna och är än idag en viktig fråga för organisationer av alla slags. Denna avhandling försöker därför undersöka bristen på insikt eller fragmenterad kunskap om organisationsdesign eller arkitektur hos moderna företag i både den akademiska världen och såväl industrin. Syftet med denna avhandling är att beskriva de utmaningarna och rekommendationerna som finns i forskningspapper, industriella vitböcker och intervjuer för att föreslå riktlinjer för bättre anpassning. Målet med denna avhandling är att tillhandahålla en inventering av tillgängliga forskningar inom området Business and IT Alignment (BITA) och organisationsvetenskap för att kunna föreslå en grund för framtida forskning. För detta ändamål har en Design Science Research (DSR) strategi följts i kombination med en litteraturstudie åtföljd av två intervjuomgångar som ett medel för datainsamling och utvärdering. Artefakterna som härrör från denna avhandling har formen av femton riktlinjer extraherade med hjälp av kodningsanalys från litteraturstudien och en första intervjuomgång hos ett stort svenskt fordonstillverkningsföretag. Riktlinjerna utvärderades därefter i en andra intervjuomgång med en branschexpert som granskade riktigheten och användbarheten av riktlinjerna. Resultaten av utvärderingen visade att riktlinjerna var användbara för både akademin och branschexperter. Därför gör det möjligt för författaren att hävda att en preliminär proposition har uppnåtts.

Abstract:
For all intents and purposes, this show is the fourth edition of the textbook Computer Organization and Design Fundamentals by David Tarnoff. Since the first edition came out in 2005, the PDFs have been made free for download to anyone interested in computer organization. With the trend toward audio and video instructional material, it was time for an update. The presentation of the material in this series will be similar to that of the original textbook. In the first third, we will discuss the mathematical foundation and design tools that address the digital nature of computers. This will include an introduction to the differences between the physical world and the digital world, how those differences affect the way the computer represents and manipulates data, and the use and design of digital logic and logic gates. In the second third, the fundamentals of the digital logic and design will be used to design common circuits such as binary adders, describe checksums and cyclic redundancy checks, network addressing, storage devices, and state machines. The final third will examine the top-level view of the computer. This will include a discussion of the memory hierarchy and its components, the components of a CPU, and maybe even a discussion of assembly language along with some examples.

Abstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Architecture, 2010.
Includes bibliographical references (p. 88-89).
This thesis investigates generative methods of architectural form finding in matter force fields that produce spatial subdivision and organizational variation. Unlike the style driven contemporary free-form architecture or decorative computational form making processes, this thesis is interested in inventing methods of informing architectural forms with constraints of matter realities, namely mechanics of matter. The consideration of matter mechanics in a conventional design process is only a post-rationalization design input. The initial form is assumed to be the datum to work with and not re-configured after the engineering input beyond thickening material. This approach resembles the mindset of the modern era architect who desires to shape the world with their own ideas of how the world should be like rather than incorporating material realities in making forms. On the other hand, in a pure material efficiency driven design process, the designer generates form that is only able to provide a single shell space of a certain span distance and height. The latter process is neither able to provide organizational variation nor programmatic subdivisions. Given the advancements in computational tools, the designer is now able to create his own tools to evaluate both material and visual performance while thinking of organizational principles. This thesis investigates opportunities that work with the constraints of material force fields to generate organizational rules for spatial constraints by inventing its own computational procedures. Topology formations, pattern formations within topological boundaries and aggregated topology formations are three main categories of form finding methods being explored throughout the thesis. The goal of this particular thesis is not to find ways to achieve optimum structural efficiency with minimum material, but rather to attain the medium between the two while generating new aesthetics and organizational rules.

Many animal behaviors consist of using special patterns of motion for communication, with certain types of movements appearing widely across animal species. Oscillatory motions in particular are quite prevalent, where many of these repetitive movements can be characterized by a simple sinusoidal model with very specific and limited parameter values. We develop a computational model of categorical perception of these motion patterns based on their inherent structural regularity. The model proposes the initial construction of a hierarchical ordering of the model parameters to partition them into sub-categorical specializations. This organization is then used to specify the types and layout of localized computations required for the corresponding visual recognition system. The goal here is to do away with ad hoc motion recognition methods of computer vision, and instead exploit the underlying structural description for a motion category as a motivating mechanism for recognition. We implement this framework and present an analysis of the approach with synthetic and real oscillatory motions, and demonstrate its applicability within an interactive artificial life environment. With this categorical foundation for the description and recognition of related motions, we gain insight into the basis and development of a machine vision system designed to recognize these patterns.

NATO: Network Architecture; Tensile Organization is a project that seeks to create a lighter public forum where architecture mediates a space of metaphor, yet looks towards a hopeful future, in a place laden with the immensity of a dark past. This project exploits the emblematic condition of connectivity within various paradigms. These states range from international and diplomatic initiatives to the structural integrity of a piece of architecture to infrastructural connectivity and finally to the simple experience of traversing a site. The program and concept are based on an interdependent network where all architectural, programmatic and urban scale constituents are connected in order to foster urban renewal at the site of Mauerpark in Berlin, a place that from 1961 until 1989 was fundamentally divided and incapable of being traversed. The project seeks to define and give meaning to ways to mend a political, infrastructural and architectural scar that has been left on a city while depicting the very real and very palpable condition of the systemic political organization of the North Atlantic Treaty Organization (NATO) Public Diplomacy Division.

Abstract:
The ventral division of the medial geniculate body (MGV) is the primary tonotopically-organized nucleus of the auditory thalamus. Previous studies have suggested a close association between the anatomical structure of the MGV and its observed functional organization, but direct correlative studies are lacking. In the present study, regional differences in the cytoarchitecture of the rabbit MGV were described. These different regions were shown to have distinct frequency organizations. The central portion of the rabbit MGV is characterized by a laminated cytoarchitecture that is formed from the orderly arrangement of highly-oriented neuronal cell bodies. In this region, there exists a steep frequency gradient that extends across the dorso-ventral axis of the nucleus, orthogonal to the cellular laminae. This frequency gradient is marked by a discontinuous and stepwise-progression of best frequency. In regions lacking a laminated cytoarchitecture, a steep frequency gradient is absent. In addition, the morphology and basic response properties of individual cells were studied with the juxtacellular labeling technique. Two morphological types of projection neurons as well as two types of putative interneurons were identified on the basis of dendritic thickness, cell soma size and spine morphology. Both types of tufted projection neurons had a variety of different response properties, but the Onset pattern and summation response to binaural stimulation predominate. Quantitative spatial analyses demonstrated that the dendritic fields of both types of tufted neurons are highly oriented. Further, for neurons within the laminated portion of the nucleus, the major axis of orientation of the dendritic fields are parallel to the cellular laminae and orthogonal to the frequency gradient. Departures from this orientation parallel changes in Nissl and functional architecture. A model is presented that correlates the discontinuous and step-wise frequency gradient in the nucleus with the size and morphology of dendritic fields. Lastly, three-dimensional reconstructions of anterogradely-labeled thalamocortical axons reveal a novel class of thalamocortical axon that has collaterals to both layer I as well as layers III/IV of primary auditory cortex; these layers were previously thought to have exclusively separate inputs. This novel class of axon is further evidence for multiple parallel channels from the MGV to AI.

The development of architectural CAD systems implies a trend of using a comprehensive building model as the storage space for all relevant data about one design project. Instead of a set of drawing files, a building is represented as a collection of building object data and their relationships. In order to create and manipulate this complex organizational structure, we have to empower the CAD system with a more sophiSticated manipulating tool than it now possess. Hypermedia, as an associative way of organizing and presenting information, is able to support the practical requirements of designers. The thesis approaches the idea from two aspects: one is to represent a building model in a data structure, based on hypermedIa nodes and links. During this authoring process, we should create a hypermedia structure which can not only cope with the original building data structure but also provide the structural basis we can use in inquiring for buIlding data in the design process. The second aspect is to browse for building information in a model embedded in a hypermedia structure. The possibilities it provides can go far beyond the constraints of conventional organizational methods. The way we access building data can be greatly broadened. The flexibility and interactivity of hypermedia are leading us to better desIgn environments, with more machine power and intelligence being brought to architectural CAD systems. From the viewpoint of system analysis, the ideas and methods, together with the potential problems the thesis discusses will be of value to the real practice of creating and managing this kind of data structure in future architectural CAD systems.

Thesis submitted in fulfilment of the requirements for the degree Doctor of Technology: Information Technology in the Faculty of Informatics and Design at the Cape Peninsula University of Technology 2013
The alignment between business and information technology (IT) strategies has been a challenge for many years. Strategic alignment models and enterprise architecture methodologies and frameworks have been developed to assist business and IT managers with improving alignment between business and IT strategies. The business analyst, systems analyst and project manager are key role players in delivering the information systems (IS) needs of business and therefore key in aligning business and IT strategies. Despite literature and research suggesting a positive influence of emotional intelligence on occupational performance in various industries, the development of emotional intelligence of the business analyst, systems analyst and project manager is neglected by software development organisations. Emotional intelligence is neglected in industry IS competency models as well as documented standards for the business analysis and project management profession (BABOK and PMBOK). Emotional intelligence is not addressed in strategic alignment models and enterprise architecture methodologies and frameworks. Emotional intelligence is equally neglected in IS literature. Systematic research investigating the impact of emotional intelligence on occupational performance of IT professionals remains sparse. The purpose of this study was to determine which emotional intelligence competencies are needed to improve the occupational performance of business analysts, systems analysts and project managers in delivering business information system needs. The study took the form of a multiple interpretive case study. Qualitative data was collected using semi-structured interviews with stakeholders from 20 software development organisations utilising the roles of the business analyst, systems analyst and project manager. Quantitative data was collected using the Genos Emotional Intelligence Inventory with the aim of identifying the patterns of emotional intelligence visible in the sample of business analysts, systems analysts and project managers assessed. The study suggests emotional intelligence has a role to play in alignment between business and IT strategies. It is proposed that industry IS competency models as well as the standards for the business analysis and project management profession as documented in BABOK and PMBOK include specific emotional intelligence competencies. The study also proposes that higher education institutions in IT/IS such as universities of technology, as well as training providers focusing on business analysis, systems analysis and project management, should focus not only on technical skills but emotional intelligence skills as well when developing the supply pipeline of business analysts, systems analysts and project managers. Keywords: Emotional intelligence, business – IT alignment, information technology, enterprise architecture, business analyst, systems analyst, project manager, competencies, non-technical skills.
