This thesis covers a product development process carried out in collaboration with Ericsson –Enclosure & Power and their development of Radio Base Stations (RBS). As Ericsson expands into new markets, the different customer demands on their support systems increases in number and variation. In order to improve their business structure and still provide a wide array of product solutions, they are currently developing a new modular product family. Today numerous methods for product modularization exist, but there is a lack of experience of using such methods at Ericsson – Enclosure & Power. This thesis is an exploration of what methods could be suitable to use in this context, and how to implement them in a beneficial way. The object of study is the Battery Base Unit (BBU), a mounting base for RBS cabinets that contains a compartment for backup batteries. A methodology is suggested for developing this product in a way that secures a proper modular structure. Part of the methodology consists of standard product development methods such as Quality Function Deployment (QFD), concept selection and prototyping. The other part consist of the modularization methods Function Structure Heuristics and Design Structure Matrix (DSM), that are employed first on functional level before developing concepts and secondly on component-based level while detailing the final concept. The thesis describes how these implementations have been made, how the product have been developed from idea to prototype and the resulting product modularity. The final design is evaluated against the product specification and the benefits and drawbacks of using a formalized modularization process for product development at Ericsson – Enclosure & Power are discussed.Detta arbete handlar om den produktutveckling som utförts i samarbete med Ericsson –Enclosure & Power och deras utveckling av kabinett för radiobasstationer (RBS). Ericssons expansion på nya marknader ökar mängden krav på deras olika supportsystem. För att kunna vidareutveckla sin verksamhet och samtidigt erbjuda ett stort antal produktlösningar utvecklar de för närvarande en ny modulbaserad produktfamilj. Idag finns ett flertal metoder för produktmodularisering men man saknar erfarenhet av att arbeta med sådana metoder på Ericsson– Enclosure & Power. Detta arbete undersöker vilka metoder som är lämpliga att använda i detta sammanhang, och hur man på bästa sätt ska implementera dem. Objektet för denna studie är Batteribasenheten (BBUn) som är ett fundament för montering av RBS kabinettet med ett utrymme för reservbatterier. Ett övergripande tillvägagångssätt föreslås för att säkerställa att utvecklingen av denna produkt inkluderar en bra modulär uppbyggnad. Delvis består tillvägagångssättet av vanliga produktutvecklingsmetoder såsom Quality Function Deployment (QFD), koncepturval och prototyper. I övrigt består det i modulariseringsmetoderna Function Structure Heuristics och Design Structure Matrix (DSM) som används först på funktionsnivå innan konceptgenereringsfasen och därefter på komponentnivå under detaljutvecklingen av det slutliga konceptet. Detta arbete beskriver hur dessa metoder har implementerats, hur produktenhar utvecklats från idé till prototyp samt den resulterande produktmodulariteten. Den slutliga utformningen utvärderas mot den angivna kravspecificeringen och fördelarna och nackdelarna med att använda en formaliserad metod för produktutveckling på Ericsson – Enclosure & Power diskuteras.

Dans cette thèse, nous nous sommes intéressés aux design, vérification et implémentation des systèmes à base de composants. Nous proposons d'abord une méthodologie de design et de vérification compositionelle et incrémentale à base de contrats pour les systèmes de composants. Nous proposons ensuite une implémentation distribuée qui permet de préserver certaines properiétés globales de ces systèmes. La méthodologie de design proposée utilise les contrats comme un moyen de contraindre, raffiner et d'implémenter les systèmes. Elle est basée sur un formalisme de contracts générique, que nous instancions pour un formalisme de composants permettant la description des propriétés de progrés. Nous étendons cette méthodologie pour raisonner sur des systèmes de taille arbitraire et nous prouvons son utilité pour vérifier des propriétés de sûreté et de progrés d'un réseau de noeuds distribués. Dans le contexte des systèmes distribués, les systèmes doivent être implémenter de manière distribuée. Nous proposons dans cette thèse un protocole qui permet l'exécution distribuée des systèmes tout en préservant certaines propriétés globales à savoir des synchronisations et des priorités et où les composants interagissent par échange de messages. Nous proposons également une implémentation du protocole pour une plateforme particulière.

Mobile robotics has become a rapidly developing field of interdisciplinary research within robotics. This promising field has attracted the attention of academicy, industry, several government agencies. Currently from security to personal service mobile robots are being used in a variety of tasks. The use of such robots is expected to only increase in the near future.
In this study, it is aimed to design and manufacture a versatile robot base. This base is aimed to be the main driving unit for various applications performed both indoors and outdoors ranging from personal service and assistance to military applications. The study does not attempt to individually address any specific application, indeed it is aimed to shape up a robotic module that can be used in a wide range of application on different terrain with proper modification. The robot base is specifically designed for mixed terrain applications, yet this study attempts to provide some guidelines to help robot designers. The manufactured robot base is tested with tracks, wheels, and with both tracks and wheels, results are provided as guidelines to robot designers. Last but no the least, this study aims to obtain the know-how of building functional and flexible robots in Turkey by facilitating local resources as much as possible.

As part of a Naval Postgraduate School's capstone project in Systems Engineering, a project team from cohort 311-081 performed a Systems Engineering analysis of an Advanced Sea Base Enabler (ASE). For a sea base to be truly beneficial a capability must exist that supports efficiently transporting needed materiel from the sea base to the desired debarkation point. The capability must support peace-time, non-combat operations' and war-time, combat operations' logistics and support needs. The solution must be cost effective and capable of operating under all environmental conditions, including sea states, under which necessary military operations are expected to take place and must support a transport rate sufficient to ensure materiel is delivered within operational time requirements. The proposed ASE is intended to fully enable the potential of the sea base. The bulk of effort by the team was on collection, analysis and validation of operational requirements, functional analysis based on the operational requirements, consideration of possible alternatives compared to the collected requirements, prioritizing the alternatives based on stakeholder priorities and selection and documentation of a preferred alternative. Addtionally, the team conducted cost analysis and risk analysis, as well as a limited simulation study.

Modern wireless communication systems transmit complex modulated signals with high peak to average ratio in order to deliver high data rates. It demands wide bandwidth and rigorous efficiency performance for power amplifiers. Today’s conventional RF power amplifiers have relatively poor operating efficiency and require more power and area for operation. Therefore, more research on high efficiency power amplifier is crucial to the growth of the wireless industry. Until recent days, WiMAX systems are using technology processes such as Gallium Arsenide (GaAs) and Si LDMOSFET to obtain the performance. Although they are providing the required functional performance, they do not optimize cost and/or size.
The primary focus of this thesis is to enhance the efficiency and output power of a compact microwave Power Amplifier suitable for a WiMAX base station. To achieve this goal, this thesis explores the highly efficient switched mode Class E microwave power amplifier using the Gallium Nitride on Silicon Carbide HFET (GaN-on-SiC) technology. The smallest gate length (0.15 µm) device recently released by NRC is used in this design. It provides higher performance at lower cost and area than the alternative Gallium Arsenide (GaAs) technology. Importance is given in designing the bias network of the device. The biasing network has a great impact on efficiency of power amplifiers. Many new techniques of Class E design have been presented to date, but there is not significant improvement related to the biasing network. A highly efficient Class E power amplifier for WiMAX base station transmitter was developed in this thesis for 2.5 GHz application. An improved bias network was introduced for biasing the active device. This successful design shows acceptable simulated performance with a gain of 10.12 dB, an output power of 34.12 dB, and a power added efficiency of 41.7 % at the peak output power.

In this Master?s thesis an optimization model for finding the optimal design of a standby base operating in remote regions is presented. The research and development within optimization of standby vessel design is limited. The objective of this thesis has been to utilize the state of the art within the areas of maritime fleet optimization, ship design optimization and the analytical hierarchy process in the development of a working model. Application of emergency preparedness assessment processes in the North Sea as quantifiable mathematical restrictions is also addressed.By developing a linear optimization model, and implementing it into optimization software, a possible solution in finding the optimal design of a standby base has been approached. The scope of the thesis has been to find the basic design of the standby base, its attributes and the fleet of cooperating standby vessels with the minimum total cost and satisfactory emergency preparedness. As an addition, the model has also been extended with a weighted objective function considering the trade-off between cost and emergency preparedness.In order to investigate the behavior of the model in producing the optimal design and functionality of a standby base, it was tested on a case study for future petroleum development near Jan Mayen. The results revealed a significant cost reduction when the standby base was implemented as apposed to only standby vessels. It also revealed that different design options proved more appropriate as a standby base when the data was run for the original model and the weighted objective function extension.Because of the limited state of the art connected to optimizing the design of standby vessels, the model in this thesis is a version of what I consider to be a possible way of developing a tool in aiding naval architects. Because of the model?s use of expert judgments, obtaining applicable results demands extensive work connected to data pre-processing.

The objective of this thesis is to design and develop a knowledge base model to support the maintenance system structure. The aim of this model is to identify the failure modes which are the heart of maintenance system through the functional analysis and then serves as adecision support system to define the maintenance tasks and finally to implement a preventive maintenance task. This knowledge base management system is suitable to design and develop maintenance system since it encompasses all necessary steps in maintenance area. Moreover, it is capable of being integrated with other knowledge base systems. The structure and the environment of this knowledge base system is flexible to allow users to deploy different kinds of tools which they will. It is also a well structured approach to develop, debug, upgrade and trace. In this thesis, the CommonKADS methodology is used as the knowledge base methodology. At the first step, a knowledge base system is developed to create the maintenance system infrastructure. To implement this, Reliability-Centered Maintenance (RCM) has been chosen as the method to design a maintenance system. In order to make it more specified, a Spindlesubsystem is taken as a case study to make the model clearer. Secondly, another knowledge base system is developed for decision making process to select the suitable maintenance task and finally, a general knowledge base model is developed for condition-based monitoring onSpindle. In chapter 1, background, previous works and gap analysis have been surveyed. Then in chapter 2 the methodology and tools have been discussed and described. Design and development the knowledge base for maintenance system is described in detail in chapter 3 and finally in chapter 4, the conclusion and the future works are presented.

The basis of a novel bipolar transistor structure was proposed by Dr R. Aubusson of Middlesex Polytechnic in 1977. The novelty lies in replacing the conventional overlay transistor's P+ base grid with a refractory metal grid, in order (a) to lower the base resistance and (b) to autoregister the emitter. It was claimed that the linearity of the transistor would also be improved. A number of questions raised by this idea have been investigated, the methods and conclusions of which are presented here. Plausible structures, using the metal base grid, are proposed and compared with conventional structures. Some advantages are seen to be possible. The current understanding of distortion analysis applied to transistors is reviewed. The main ideas are presented in a unified manner and are extended to higher order. A number of the transistor's second order effects are analysed in a novel fashion. The metal base grid transistor is analysed and compared with conventional transistors, with favourable results. Practical aspects of fabricating the metal base grid transistor were investigated. A procedure for deposition has been determined and is presented here along with the film physical and electrical characteristics. Analysis of the tungsten-silicon interface shows the suitability of the metallization as a base grid. Suitable means of delineating the tungsten film have been assessed and a working procedure determined. Subsequent deposition of various insulators has been investigated and the problems associated with the readily oxidized tungsten film have been overcome. Formation of the emitter, requiring further high temperature processing, has been assessed in view of the limitations imposed by the preformed base metallization. In summary, it has been shown that the novel structure can be constructed and that significant performance improvement is to be expected, although a full realization was not possible within the resource constraints of the project.

Tese de Mestrado em Design de ModaEsta investigação explora o fenómeno da Sinestesia - mistura e associação de sentidos - como base criativa na área do Design de Moda. Será que as percepções sinestésicas de um indivíduo fornecem dados suficientes para serem a única base de inspiração na concepção de vestuário? Para constituir hipótese, foi efectuada uma investigação sobre a sinestesia, as suas variantes e as suas condicionantes, e sobre a concepção de vestuário e os elementos essenciais a ter em conta no desenvolvimento de uma colecção de moda. A hipótese colocada pela investigadora foi que de facto a sinestesia pode ser a única inspiração na concepção de uma colecção, dado que as percepções sinestésicas incluem cores, formas, texturas e manchas/padrões - dados que vão de encontro aos elementos do design essenciais à concepção de vestuário. Para provar a hipótese, realizou-se um projecto experimental envolvendo um grupo de casos de estudo, todos sinestésicos, que culminou na concepção de um projecto de moda baseado exclusivamente nos dados provenientes dessa experiência. O projecto foi o principal objectivo da investigação e constitui a validação da hipótese, sendo a sua prova prática. A colecção final é um espelho do trabalho de investigação, dos quatro sinestésicos que participaram na experiência e do fenómeno da sinestesia em si. Obteve-se, assim, o resultado perfeito para uma investigação cuja uma temática é tão fascinante e fora do comum. Este projecto de investigação prova ainda que é possível a interligação de duas áreas completamente distintas - a Neurologia e o Design de Moda - de maneira harmoniosa e bem sucedida, originando um resultado inovador, que faz jus à temática da sinestesia e é enriquecedor para ambas as áreas.
This investigation explores the phenomenon of Synesthesia - a mix and association of senses - as a creative basis for Fashion Design. Can synesthetic perceptions provide enough data to be the only inspiration in the creation of clothes? In order to create an hypothesis, a deep investigation was carried out, focusing synesthesia and its variants, as well as the conception of clothing and the elements we have to keep in mind while creating a collection. The hypothesis was that indeed synesthesia could be the only inspiration in the conception of a collection, since synesthetic perceptions include colors, shapes, textures and patterns – all of which conform to the design elements that are essential to the conception of clothing. In order to prove this hypothesis, an experimental project took place, implicating a group of case studies, all synesthetes, that culminates with the conception of a fashion project based exclusively on the data gathered from that experience. This project was the main goal of the investigation and it is the validation of the hypothesis, its practical proof. The collection mirrors the investigation, the four synesthetes that took part in the experience and the phenomenon of synesthesia itself. This way, starting with a very unusual, peculiar and fascinating subject, we managed to reach a perfect conclusion for our investigation,. This project also proves that it is possible to connect two completely different areas – Neurology and Fashion Design – harmoniously and successfully, creating an innovative result that merits synesthesia and enriches both areas.

Web maps are today used more than ever. These are often displayed in geographical information system solutions. Web maps are often constructed in the terms of different layers where the bottom-most layer is called base map or background map. A specific kind of base maps are those that are the canvas for utility networks. These base maps can look vastly different from each other. Sometimes the base map can be overlooked. Currently there are different theories and opinions on how these base maps shall be designed and what information they shall contain. This thesis investigates a suitable base map design for utility network management and also creates some prototypes as a proof of concept. The thesis focus mostly on three factors, colour, information visualisation and symbology. This is investigated by using a user-centred design approach and comparing it to existing findings in literature and among map theories. The user-centred design process involves a case study performed with participants that work with utility networks in web map solutions. The research method is an iterative process where the participants are answering three quantitative surveys. The surveys includes prototypes which is refined for each step after analysing the participants answers. The thesis concludes that low saturated colours is good practise to enhance the network, this is both evident in literature as well as in the case study. Amount of lightness in the base map seem to be more of a opinionated matter and can highly differentiate depending on users device. Using hue is recommended to make borders between map elements more distinct. The base map shall only obtain the most relevant information and more specific information is recommended to be added through additional layers. Further studies need to be done in order to investigate the networks design and there is also a need to investigate how a map solution with several layers shall be design and how the relationships between those layers shall be constructed for utility network management

Der volle Inhalt der QuelleAnnotation:
This thesis describes the system design and implementation of the secure Ephemerizer System that was first introduced by Radia Perlman in 2005. The system is designed to enable users to keep data for a finite period of time before making the data unrecoverable by destroying the keys with which the data was encrypted. The task of the Ephemerizer System service is to create, advertise, and destroy keys required for the Ephemerizer System's functionalities.
We designed the Ephemerizer System Service's security by placing the sensitive key management modules into a Trusted Computing Base (TCB). Our compartmentalized approach distributes security requirements at different sensitivity levels into different protection domains. In our approach, we implement the trusted protection domain (our TCB) on a tamper-resistant Javacard.
We placed the key storage database into the partly trusted protection domain to improve scalability and availability of the Ephemerizer System. The partly trusted protection domain requires memory isolation and other security mechanisms provided by the underlying operating system. We implemented several mechanisms on the TCB, such as the signature engine, cryptographic modules, the on-card expiration validator, and on-card time verification. We make the Ephemerizer System available to users as a web service and expose it though a uniform API. This approach enables the seamless integration of the Ephemerizer System into business processes on heterogeneous platforms.

A presente pesquisa considera que a moda passa a ser pensada, no contexto contemporâneo, de forma sistêmica e complexa, segundo os princípios teórico-metodológicos do design. Para atingir essa dimensão, a moda e o design se aproximam cada vez mais, quer pela prática, quer pela teoria, constituindo-se num universo de cultura de projeto. Logo, o design de moda, como cultura de projeto, pode ser questionado segundo os pressupostos do design estratégico. Dessa forma, esta pesquisa tem como objetivo discutir o design de moda como cultura de projeto com base nos conceitos que definem o design estratégico para a configuração de uma metodologia de projeto estratégico aplicada ao design de moda no contexto industrial. Justifica-se a abordagem proposta tendo em vista que a configuração de uma metodologia de projeto estratégico aplicada ao design de moda torna-se fundamental como plataforma de conhecimento para a prática projetual na indústria da moda como estratégia de inovação. Nesse sentido, a metodologia adotada para a realização da pesquisa consiste num estudo de caso, desenvolvido por meio de entrevistas com gestores e designers de três indústrias no segmento da moda localizadas na sede do município de Erechim/RS. A análise dos dados obtidos no estudo de caso e o cruzamento dessas informações com a fundamentação teórica possibilitaram o entendimento do processo de design de moda no contexto industrial. Da mesma maneira, a relação estabelecida entre os métodos de projeto desenvolvidos no design de moda e no design estratégico possibilitou a identificação de princípios teórico-metodológicos complementares ao processo de design de moda, sobretudo considerando os limites e contribuições do design estratégico para o design de moda. Por sua vez, o estudo realizado permitiu responder à problematização desta pesquisa, ou seja, o que define o design de moda no contexto industrial e qual é a contribuição do design estratégico para o design de moda. Ao final, sugere-se uma metodologia de projeto estratégico aplicado ao design de moda, atingindo, assim, os objetivos propostos nesta pesquisa.
This investigation shows that fashion is becoming to be thought, in the contemporaneous context, in a complex and systemic way, according to the theoretical-methodological principles of design. To reach this dimension, fashion and design more and more approach to each other, both in practice and in theory, constituting a universe of culture of project. Thus, fashion design, as culture of project, may be questioned according to the conjecture of strategic design. This investigation aims at discussing fashion design as a culture of project, based on the concepts which define strategic design for the configuration of a methodology of strategic project applied to fashion design in an industrial context. This approach is justified due to the fact that the construction of a methodology of strategic project applied to fashion design is fundamental as a knowledge platform for project practice in fashion as innovation strategy. In this sense, the adopted methodology for the performance of this investigation consists of a case study, developed by means of interviews with managers and designers of three factories in the field of fashion located in the city of Erechim/RS. The analysis of data obtained through the case study and the crossing of this information with theoretical basis made possible the understanding of the process of fashion design in an industrial context. In the same manner, the relation established among the methods of the project developed in fashion design and in strategic design made possible the identification of theoretical-methodological principles complementary to fashion design process, mainly when considering the limits and contributions of strategic design for fashion design. On its turn, the study allowed to answer the problem of the investigation, that is, what defines fashion design in an industrial context and what the contribution of strategic design for fashion design is. Finally, a methodology of strategic project applied to fashion design is suggested, this way, fulfilling the objectives here proposed.

Fundação de Amparo à Pesquisa do Estado do Rio de JaneiroKlaxon, Base and Noigandres are three brazilian magazines that serve as examples of avant garde publications in which graphic design was instrumental to display ideas shared among the artistic groups involved on its making. They are landmarks of the modern design, fitting in the concept of erudite product (bourdieu), aimed not at the general public, but to a group of pairs that shared esthetic values and who shared aesthetic values and ambitions to the condition of the vanguard in their respective artistic fields. These magazines are exponents of the field of modern graphic design, which only became institutionalized as a field of production in the 60s with the creation of ESDI and the beginning of the concrete movement in the arts.
As revistas Klaxon, base e Noigandres são exemplos de revistas de vanguarda em que o design gráfico foi usado como instrumento para a expressão de idéias, compartilhadas pelos grupos artísticos envolvidos em sua publicação. São marcos do design moderno, encaixando-se no conceito de produto erudito (Bourdieu), destinado não ao grande público, mas a grupos de pares, que compartilhavam os valores estéticos e as ambições à condição de vanguarda em seus respectivos domínios artísticos. Estas revistas são expoentes do campo do design gráfico moderno, que só viria a se institucionalizar na década de 60, com a criação da ESDI e o surgimento do movimento concretista nas artes plásticas.

What might count as the technological knowledge bases (or underpinning) of design practice (and more particularly, Industrial Design, and Design and Technology in general education) has always been an unresolved matter. This series of papers, developed through an action research approach over a number of years, sought to develop understanding of the technological knowledge base of design, (taking account, also, of the apparent needs of Industrial Design practitioners and of those engaged in Design and Technology in schools). Hence, a theoretical position and research agenda developed concerning the nature of technology for (the purposes of those engaged in) designing. Three areas have been explored through a case study format: designing and materials and processes at advanced (A) and advanced supplementary (AS) level in UK Design and Technology syllabuses; the teaching and learning of mechanics and materials technology by Industrial Design and Technology undergraduates; the use of flexible learning and information technology (IT) to support the analysis of structures by Industrial Design and Technology undergraduates.

YesRF power amplifiers in mobile WiMAX transceivers operate in an inherently nonlinear manner. It is possible to amplify the signal in the linear region, and avoid distortion, using output power back-off; however, this approach may suffer significant reduction in efficiency and power output. This paper investigates the use of Doherty techniques instead of back-off, to simultaneously achieve good efficiency and acceptable linearity. A 3.5 GHz Doherty RFPA has been designed and optimized using a large signal model simulation of the active device, and performance analysis under different drive levels. However, the Doherty EVM is generally poor for mobile WiMAX. Linearity may be improved by further digital pre-distortion, and a simple pre-distortion method using forward and reverse AM-AM and AM-PM modeling. Measurements on the realized amplifier show that this approach satisfies the EVM requirements for WiMAX base stations. It exhibits a PAE over 60%, and increases the maximum linear output power to 43 dBm, whilst improving the EVM.

This study is about using the performance-based design for base-isolated buildings . The study introduces an example isolated building, which is a 15-story reinforced concrete building that was simulated and designed by MIDAS software . First , it set performance targets for the isolated building . The targets include the behavior of the specification , the peak ground acceleration of performance point , and toughness ratio . Second , in the study , the axial forces of column are not the same for each building, so it has to design the isolator according to the axial force of column . Then , I find out the performance point , which is the moment when the isolator is broken, and obtain the seismic base shearing force and ultimate peak ground acceleration . Next , the study decided a combination of isolators to complete the design of the isolation layer . Third , according to the base shear force of upper structure at performance point , it adjusts seismic base shearing force for design . Then , the study decided the reinforcement of structure to complete the design of upper structure . Finally , the study has to check whether the design matches the original targets . The seismic base shearing force for design must to be re-adjusted until it matches the performance targets . As a result , the values of the study are in line with the performance targets , and verify that the design process is feasible . There are three ideas that we can learn from the process of designing isolation building. First , the peak ground acceleration of performance and toughness ratio can be used as the performance targets to design the base-isolated buildings . Second , it is more reasonable and conservative to use the design spectrum ,which is acted by 2500-year regression period seismic force ,to calculate the peak ground acceleration of performance. Third , the seismic base shear for design of specification is so conservative that the yield strength is too high. For reference and comparison of people working in civil engineering industry, this study provides a complete design process with performance-based design for base-isolated buildings .

In organic synthesis, controlling stereochemistry can be a challenge whether you are working with small molecules or larger natural products. Current chiral bases, such as Sparteine, are difficult to make or expensive to purchase. Their other drawback is that many chiral bases only can access one stereochemical configuration, not both. In the work presented here, progress has been made towards developing a chiral base from an amino acid derivative, L-valine. The chiral base has been fully synthesized. The use of the amino acid starting material, allows for us to make both the R and S selective amino acid. Efforts are being made to determine the efficacy of the base to control stereochemistry.

In recent year , GIS technology has been successfully applied to a variety ofdomain applications. The accumulated GIS data volume grow fast over the pastyears. End users requesting GIS data sooner or later will have to deal Withsuch problems as：How to efficiently request and manage GIS data to meet different domain needs ? How to effectively realize the content of GIS data , as to determine if it applicable ?How to manage various thematic data from different resource in GIS environment ?Such obstacle will surely impede the progress of future GIS. This research suggests an approach to build a metadata database to manage a variety of GIS data and aid users understanding toward data. After analyzing the way GIS datais managed , the metadata design consists of three major categories : DB , fileand layer. Users can determine if the data meet demands with the aid of metadatadatabase. Since metadata design is the key factor for this research , the designstrategy of this research is based on a primitive and general perspective thatcan used in different type of GIS data.The research also introduces an object-oriented concept onto Relational DatabaseManage System. Such concept provides a new direction for layer-based GIS to generate "virtual" thematic data that is previously not existed. distribution the result demonstrates that an appropriate design will help the data and communication in GIS environment. By applying object -oriented conceptsto data management mechanism will increase efficiency and flexibility in GIS data retrieval.

Binary number representation is widely used in various digital electronic systems. With the improvement of the quality of life, the circumstance of mobile telecommunication and multimedia applications needs great and complex computational costs. These costs result in costly hardware design and high power consumption. For security application, RSA operand size needs 1024 bits or greater in length meaning such that it is difficult to achieve high data throughput rates. In RSA cryptography system, there is considerable to adopt DBNS (Double Base Number System) encryption. Base on the recent researches, DBNS can reduce the execution times of modular multiplication and increase the efficiency of RSA Cryptography. This paper makes Double Base Number System be a spindle and apply our fruitful results in Modular exponentiation. DBNS (Double Base Number System) is a new number representation which can be used for low-power and high-speed logic implementation. This thesis presents a fast Binary-to-DBNS conversion approach and hardware design. In DBNS system, the input binary number is firstly converted into Radix-4 form. Then the accurate DBNS representation is obtained by simple and fast logic simplification. Comparing to the exhaustive search approach which is the only one conversion method up to now, our proposed algorithm can achieve more 100 times faster than the exhaustive method. For hardware design, the proposed converter can be implemented by simple logic circuit instead of large LUT tables. This makes that the proposed converter is suitable to efficient VLSI chip implementation.

The microwave communication is a kind of communication method using wireless transmission, so there is no need to use transmission medium. Owing to the specialty, it takes less time and cost than wire transmission when establishing system. Although the transmission bandwidth is not as good as fiber optical communication-the best wire transmission type used in backbone network, it is sufficient for the communication flow of trunk circuits. Therefore, using microwave communication to establish trunking base station is an economical and efficient method. Nevertheless, the feasibility evaluation of microwave trunking base station establishment in practical depends on an on-site factitious test. This test takes too much time and labor cost to complete the evaluation. So it needs to be improved and simplified. This thesis designs a simulation procedure to evaluate the feasibility, and verify the result by on-site factitious test. The goal is replacing the factitious test to increase the establishment efficiency.

The main objective of this thesis discusses design of antennas for LTE base stations. This study proposed a multi-band antenna for telematics applications. The multi-band was constructed by combining three antennas, operated in three different frequency bands, on the system ground plane. The proposed antenna includes a dual polarization array antenna operates in the TD-LTE (2300 MHz ~ 2700 MHz) band. The dipole array antenna is designed for WiMAX application. The third antenna, PIFA antenna, operates in the Wireless LAN band. At the beginning of the design process, there were only two antenna designed for WLAN. To reduce the interference between the two WLAN antennas, an additional antenna, acted as a resonator, is placed between the original two WLAN antennas. The resonator is used to block surface currents and improve the isolation between each source on the system ground. The results show that three antennas both operate in acceptable bandwidth. The isolation for the additional antenna also shows less than 20 dB.

Video codec have been an active research area for years. Most standards such as H.26X and MPEG-X are block DCT (Discrete Cosine Transform) / DM (Differential Modulation) based. Recently, MPEG-4 provides very good coding efficiency compared to other methods. However, the complexity of a MPEG-4 encoder makes hardware solutions very expensive. Furthermore, it usually requires a powerful CPU as the controller if real-time compression is desired. Recently, Wavelet based image coding methods become more and more popular when compared to DCT based JPEG because they usually enjoy higher compression ratio. In this thesis, a block Wavelet based video codec combined with DM coding scheme is presented. An efficient modified SPIHT (Set Partitioning in Hierarchical Trees) is proposed for easy hardware implementation. A low complexity lifting based DWT (Discrete Wavelet Transform) is also designed. Straightforward coding strategies and coding without table make the hardware implementation much easier compared to MPEG-4. The entire codec can be hardwired without the use of a CPU controller if desired. Note that the overall performance can be further improved if more complicated coding schemes are used. The overall gate count is less than 85000 when designed with Synopsys and TSMC .35 cell library. When the system runs at 40 MHz clock rate, it achieves VGA resolution at 30 frames per second. Low cost and high quality make the proposed design very attractive for portable IA (Information Appliance) devices where cost and power consumption are critical. The proposed system is also verified over an Altera APEX 20K FPGA evaluation board.

The objectives of this study are to investigate the design and analysis of the column base plates in the steel buildings. According to the version of ASD(1989), LRFD(1986), LRFD(1993), LRFD(1999) and AISC(2005) which published by American Institute of Steel Construction (AISC) to be the object of this study. All theory of column base plates in these versions would be detailed, include the dimension (N and B) and the thickness (tp) of the column base plate, and by the calculation of the example we could know well about the meaning of the specification. Moreover, we can compare the difference of these versions. On the other hand, when we discuss the effect of column base plate which caused to the moment, we also introduce the design and the theory about resistance of the column base plate to the moment clearly, and we would compare the difference of ASD(1989), LRFD(1993), LRFD(1999) and AISC(2005). By the outcome of this research, we found out the version of AISC(2005) is more economic than the version ASD(1989) when using the way of Allowable Strength Design(ASD), and we could get the same size and thickness when using the way of Load and Resistance Factor Design(LRFD). And we could get more economic size of design of the column base plate by the way of Load and Resistance Factor Design (i.e., LRFD(1986),LRFD(1993), LRFD(1999) and the LRFD parts of AISC(2005)) than the way of Allowable Strength Design(ASD).

This design proposes a vision-based monitoring system. The hardware and software consist of infrared sensor circuit, rotary mechanism, controller, MySQL database, remote monitoring, moving target detection and color tracking. The system uses eight infrared sensors to detect the burglar. The sensors are installed in a fixed octagon platform. When a burglar enters, the developed system detects the locality of the burglar according to the sensory results. A pan-tilt-zoom (PTZ) camera is immediately rotated to aims the burglar according to the detection results of locality. Because the rotation of PTZ camera is less than 360 degree, a rotation mechanism is designed to rotate the PTZ camera. Image processing technologies are first used to find a rectangle region that covers the image of the burglar for tracking initialization. Color feature analysis is used for tracking. An algorithm will be proposed for tracking the burglar. Color feature analysis, mean shift, and fuzzy rule inference are used to control the pan/tilt/zoom motor of PTZ camera for tracking the burglar. The algorithm must make the camera monitor the burglar image precisely by the mean shift method and Fuzzy sets rules. To meet the real time requirement, all possible condition will be offline processed to build a decision table. The decision table is used for the system to implement the tracking algorithm. The system successfully detects and tracks the moving man in the experiments. The target image will be always shown in a camera’s view. The SQL database is setup for sending the message of remote control. The user easily controls the PTZ camera by Internet

A user oriented test data base(TDB) provides various functions when used in different phase of IS development. In system testing, TDB can certify the correctness and consistency of software in verification and validation process by uncover the hidden problems in systems. If prototyping methodology is used in analysis and design phase, a user oriented TDB can enhance user involvement in employs iterative process to get the feedback from the developers/users and modify intermediate product towards satisfactory performance. In addition, when developing IS with pakages, a user oriented TDB can be used in user training and learning to make sure that pakages are perform accurate functions in practice. Thus, how to construct a TDB becomes an important issue in the imformation system planning and development. Based on concepts of simulation and statistical methods,the study analyze the fidelity of TDB. In order to create the TDB a framework of TDBG (Test Data Base Generator) is proposed. The components of TDBG is discussed and a set of procedures to create TDB are described. The study conducts a case study to illustrate how proposed approach can be implemented. By applying the TDBG, a test data base with fidelty and adequacy can be realized.

Meeting quality of service (QoS) requirements for various services in networks has been very challenging to network designers. Besides of increase the bandwidth of network directly, it must allocate bandwidth and bound delay to meet the requirements of each application. The traditional scheduling mechanism can not meet differentiated service requirement. We will develop the scheduler, which can provide differentiated service for each priority flow. There are two major complexities about scheduler:1)calculating time stamps and system potential; and 2)the packet sorting to determine the transmission order. we would evaluate the scheduler algorithm from three properties: 1)minimum service rate、2)deterministic delay bounds and 3)fairness service, and the four influences on traffic: 1)Delay, 2)Jitter, 3)Throughout and 4)Loss rate. This paper provides performance analysis and the VLSI architecture design of the packet scheduler. Currently, WFQ has excellent performances which includes minimum delay bound and fairness, but it calculating complexity is , where N is the number of session. Because of the high complexity, we adopt Self-Clock Fair Queuing（SCFQ） which emulates WFQ, and its performance approximates to WFO and the calculating complexity is . For the hardware implement, we use “shorten length field” and “artificial weights” to reduce calculating time. We also adopt two skills: 1）Zone Compare, and 2）time stamp search engine, to determine the transmission order. These two skills can be implemented with RAM-base CAM-base in hardware design separately, and them can overcome roll-over problem. By the above skills, the VLSI architectures for scheduler are proposed to support high speed network scheduling.

Current design of column base plate only considers the effect of axial load and uniaxial bending. Some concerns have also been expressed as to the possibility that base plates designed by current code may behave more rigidly than expected. Hence, this paper will discuss the effect of new design method and propose biaxial bending design method. Here are the topics that will be analyzed by finite element program: thickness of base plate, the size and amount of anchor rod, stiffer and the effect of biaxial bending with axial load. Based on the previous researches, the base plate in new design method will develop certain plasticity with some yield zone in column, which is a better ductile behavior comparing with the design of current method, and can be successfully applied to new biaxial bending design method.
