Full textAbstract:
<p> The complexity of the manufacturing process has motivated manufacturers to consider testability as a requirement to assure the reliability and the functionality of each of their designed circuits. One of the most well-known test techniques is called Built-In-Self-Test (BIST). A BIST Universal Asynchronous Receive/Transmit (UART) has the objectives to firstly satisfy specified testability requirements and to secondly generate the lowest-cost with the highest performance implementation. UART has been an important input/output tool for decades and is still widely used. Although BIST techniques are becoming more common in industry, the additional BIST circuit that increases the hardware overhead increases design time and performance degradation is often cited as the reason for the limited use of BIST. </p><p> This project focuses on the design of a UART chip with embedded BIST architecture using Field Programmable Gate Array (FPGA) technology. The paper describes the problems of Very-Large-Scale-Integrated (VLSI) testing followed by the behavior of UART circuit using Verilog. In the implementation phase, the BIST technique will be incorporated into the UART design before the overall design is synthesized by means of reconfiguring the existing design to match testability requirements. The UART is targeted at broadband modems, base stations, cell phones and other designs. BIST is a design technique that allows a circuit to test itself. In this project, the test performance achieved with the implementation of BIST is proven to be adequate to offset the disincentive of the hardware overhead produced by the additional BIST circuit. The technique can provide shorter test time compared to an externally applied test and allows the use of low-cost test equipment during all stages of production.</p>

Alwan, Abdulrahman. "Implementation of Wavelet-Kalman Filtering Technique for Auditory Brainstem Response." Thesis, Linköpings universitet, Informationskodning, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-85116.
Full textAbstract:
Auditory brainstem response (ABR) evaluation has been one of the most reliable methods for evaluating hearing loss. Clinically available methods for ABR tests require averaging for a large number of sweeps (~1000-2000) in order to obtain a meaningful ABR signal, which is time consuming. This study proposes a faster new method for ABR filtering based on wavelet-Kalman filter that is able to produce a meaningful ABR signal with less than 500 sweeps. The method is validated against ABR data acquired from 7 normal hearing subjects with different stimulus intensity levels, the lowest being 30 dB NHL. The proposed method was able to filter and produce a readable ABR signal using 400 sweeps; other ABR signal criteria were also presented to validate the performance of the proposed method.

Full textAbstract:
This thesis reports on the design, simulation and implementation of a novel Implementation for a Wavelet-based Broadband Signal Detection System. There is a strong interest in methods of increasing the resolution of sonar systems for the detection of targets at sea. A novel implementation of a wideband active sonar signal detection system is proposed in this project. In the system the Continuous Wavelet Transform is used for target motion estimation and an Adaptive-Network-based Fuzzy inference System (ANFIS) is adopted to minimize the noise effect on target detection. A local optimum search algorithm is introduced in this project to reduce the computation load of the Continuous Wavelet Transform and make it suitable for practical applications. The proposed system is realized on a Xilinx University Program Virtex-II Pro Development System which contains a Virtex II pro XC2VP30 FPGA chip with 2 powerPC 405 cores. Testing for single target detection and multiple target detection shows the proposed system is able to accurately locate targets under reverberation-limited underwater environment with a Signal-Noise-Ratio of up to -30db, with location error less than 10 meters and velocity estimation error less than 1 knot. In the proposed system the combination of CWT and local optimum search algorithm significantly saves the computation time for CWT and make it more practical to real applications. Also the implementation of ANFIS on the FPGA board indicates in the future a real-time ANFIS operation with VLSI implementation would be possible.

Akehurst, David H. "Model translation : a UML-based specification technique and active implementation approach." Thesis, University of Kent, 2000. https://kar.kent.ac.uk/21926/.
Full textAbstract:
Many software applications involve models of data that are manipulated by the application. There is often a need to transform (or translate) the data from one model, into another in which the data is differently structured. In addition, there is an increasing requirement to pass data between different applications, which invariably have different formats for their data models. Both of these issues require a translation of the modelled data from one form to another. The process of translating a model from one form to another is known as model transformation or model translation. The literature on model transformation includes a number of techniques for specifying transformations. However, the majority of these techniques are grammar-based specifications, many of which use a textual grammar, although some make use of graphical (graph) grammars. These subsequently lead to a monolithic one-step implementation process that performs the transformation. This thesis addresses two issues that are related to the area of model transformation. Firstly, it addresses the need for a standard notation that can be used for writing model translator specifications. Secondly, a technique for implementing model translators is developed that actively performs the transformation. Rather than a single step process, that must be executed every time the source model changes, the active implementation approach presented performs a continuous translation updating the target model every time a change is made to the source model. The specification technique makes use of the standardised Unified Modelling Language (UML) and Object Constraint Language (OCL) for specifying a transformation relationship between two object-oriented models, each of which is also specified using UML and OCL. The implementation approach uses an event-based version of the observer pattern enabling the construction of translator to be formed from a number of mini-translator parts, each of which monitors a small set of components. These mini-translators act upon events generated by the model components and update the transformed components to reflect the changes. The specification and implementation techniques described can be applied to many problem areas. In particular this thesis discusses their application to Multiple View Visual Languages (i.e. the UML itself) and automatic performance model generation.

Posva, Ferdinand. "Setup Implementation for a Direct Measurement Technique of the Magnetocaloric Effect." Thesis, KTH, Materialvetenskap, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-277910.
Full textAbstract:
This project presents an attempt to construct a setup and implement a reliable technique for measuring the magnetocaloric effect (MCE) on various materials via a direct method for the acquisition of the data. The main objective of the latter is to produce a ∆Tadiabatic vs T graph over a reasonable temperature span (-100◦C up to 220◦C) by thermal monitoring of a magnetic material exposed to an oscillating magnetic field with a maximum strength of 1.2T. The setup consists of a vacuum-insulated glass tube containing the sample placed between two electromagnets of a vibrating-sample magnetometer (VSM) and increasingly heated by a resistance wire, while the temperature is recorded directly by a thermocouple. The first experiments are performed on Gadolinium (Gd) samples as a reference material in order to verify the overall reliability of the system. The obtained results on Gadolinium show that meaningful data can be acquired with this direct method, although the initially-extracted ∆Tadiabatic near room temperature stands at the accuracy limit (25%) generally accepted with this method. Unexpected interference signals from the thermocouple are encountered for high temperatures and are shown to be due to magnetic dependence from one of its constituents. Data from high temperatures can however be reliably corrected with respect to a baseline signal from a neutral nonmagnetic material. As such magnetocaloric properties of two Manganese-rich high entropy alloys are investigated with one exhibiting at most ∆Tadiabatic = 0.2◦C at its Curie temperature TC = 60◦C. Suggestions regarding the possibility of operating the setup at sub-zero temperatures are put forward and promising results from a new spot- welded thermocouple show a significantenhancement of the initial setup accuracy.<br>Detta projekt presenterar ett försök att konstruera en installation och implementera en pålitlig teknik för att mäta den magnetokolorisk effekten (MCE) på olika material via en direkt metod för insamling av data. Det sistnämnda syftet är att producera en ∆Tadiabatisk vs T över ett rimligt temperaturintervall (-100◦C up to 220◦C). Detta genom en termisk övervakning av ett magnetiskt material utsatt för ett oscillerande magnetfält med en maximal magnitud på 1.2 T. Utrustningen utgörs av ett vakuumisolerade glasrör som innehåller provet, vilket är placerat mellan två elektromagneter från en vibrating-sample magnetometer (VSM) och som stegvis värms upp av en resistanstråd, medan temperaturen registreras direkt av ett termoelement. De inledande experimenten utförs på prover av Gadolinium (Gd) som referensmaterial för att verifiera systemets totala tillförlitlighet. De erhållna resultaten från Gadolinium proverna visar att meningsfulla data kan produceras med denna direkta metod. Även om de extraherade ∆Tadiabatisk vid rumstemperatur befinner sig inom precisions gränsen (25%), vilken är allmänt accepterad med avseende på den direkta metoden. Oväntade missvisande signaler från termoelementet uppträder vid höga temperaturer och visar sig bero på magnetiskt beroende från instumentet. Data från höga temperaturer kan emellertid pålitligt korrigeras med en baslinjesignal från ett neutralt icke-magnetiskt material. Därmed undersöks de magnetokoloriska egenskaper hos två Mangan-rika hög entropi legeringar, där en uppvisar som högst ∆Tadiabatisk = 0.2◦C vid dess Curie-temperatur TC = 60◦C. Förslag beträffande möjligheten att använda installationen vid temperaturer under noll läggs fram. Lovande resultat från ett nytt punktsvetsat termoelement visar en betydande förbättringav den inledande installationens noggrannhet.

Full textAbstract:
The power supply designers choose flyback topology due to its promising features of design simplicity, cost effectiveness and multiple outputs handling capability. The designed product based on flyback topology should be smaller in size, cost effective and energy efficient. Similarly, designers focus on reducing the circuit losses while operating at high frequencies that affect the converter efficiency and performance. Based on the above circumstances, an energy efficient open loop high frequency flyback converter is designed and operated in MHz frequency region using step down multilayer PCB planar transformer. The maximum efficiency of 84.75% is observed and maximum output power level reached is 22.8W. To overcome the switching losses, quasi-resonant soft switching technique is adopted and a high voltage CoolMOS power transistor is used.

Philosophiae Doctor - PhD<br>The rapid expansion of the ART programme in South Africa has placed an additional
service demand on an already stretched public health infrastructure. The main aim of this
study was therefore to analyse the implementation of the ART programme in KwaZulu-
Natal province using the Donabedian Model of structure, process and outcome in order
to develop an ART delivery model. Ethical approval to conduct this research was issued by
the University’s Senate Research Committee. The first phase of the study used a
descriptive quantitative approach to review existing data from government departments
to analyse the ART programme. A checklist with the list of indicators for the three
elements of the study; the structure, process and outcome were used to collect data. A
pilot study was conducted and the Cronbach Alpha test was used to determine the rigour
of the study. In the second phase, a systematic review of studies on implementation of
the existing models of ART programme was conducted using quantitative descriptive
approach. The Quality Appraisal Tool was used to determine the validity of the research
findings from the literature. In phase 3, both qualitative and quantitative approaches
were used to conduct the Delphi study which included a group of experts in the field of
HIV and ART programme. Responses from the participants were modified to determine
the reliability of the study. The study found that there were structural problems such as
shortages of antiretroviral drugs and delays in the return of laboratory results. The
systematic literature review found that there were only two community-based ART
models in South Africa, namely; the adherence clubs and community-based adherence
clubs. These two models of ART delivery were implemented only in Cape Town.

Full textAbstract:
<p> This thesis implements a state-of-the-art solution separation advanced RAIM (ARAIM) algorithm as it is written as reported in the literature. Specifically, a GNSS fault detection and exclusion algorithm for a multi-constellation GNSS was implemented in software and tested against simulated data. RAIM algorithms have been created in many forms over the last couple of decades and are still in development today. The position solution results produced by this ARAIM algorithm were compared to that of a snapshot weighted least squares (WLS) solution in which failed satellites are removed before processing and an WLS solution with no corrections applied. In addition, the difference in position solution between ARAIM and the simulation truth was compared to the ARAIM reported horizontal and vertical protection limits, as well as, the position performance criteria. This thesis also investigates the performance of the exclusion method and how it affects the performance of the overall ARAIM algorithm. The algorithm implemented and tested in this thesis will be used as a basis of comparison for on-going research into robust GNSS processing techniques. </p><p>

Ingeniera Civil Eléctrica<br>La Tomografía de Ruido Ambiente (ANT) consiste en una técnica de busca modelar áreas
y estructuras cuya novedad es que utiliza el ruido ambiente como herramienta. Este tipo
de señal suele ser eliminada en técnicas como la Tomografía Sísmica (TS), la cual es la
más ampliamente utilizada, especialmente en el área de la minería para la exploración de
yacimientos. A diferencia de ANT, ésta hace uso señales de alta energía como terremotos
y explosiones artificiales, por lo tanto, dentro de su procesamiento elimina este ruido. En
zonas con baja actividad sísmica no es posible utilizar TS, por lo que es necesario desarrollar
técnicas alternativas. ANT es una de las opciones que cumple, además de ser amigable con
el medio ambiente.
Una de las problemáticas tanto de ANT es que no cuenta con un ground-truth. Dado
esto, no se puede saber con certeza qué tan cercano es el modelo estimado a la realidad. Para
intentar resolver esto, actualmente sismólogos contrastran los resultados provenientes de ST
o usan información de previo conocimiento del área, pero no es suficiente.
Era necesario el desarrollo de una plataforma sintética, que fuera lo más cercano a la
realidad posible. Sobre ésta se implementa la técnica de tomografía de ruido, con el objetivo
de identificar las variables que influyen en la estimación, tales como la posición de estaciones,
la frecuencia de la fuente, velocidad del medio, entre otras. También esta plataforma debe
cuenta con un ground-truth para determinar los errores de estimación.
En el presente trabajo, ésta plataforma fue implementada en lenguaje Python. Cada etapa
de la metodología y fue probada sobre tres escenarios sintéticos con diferentes caracteríasticas
de estructura. Se estudiaron las variables de interés y se realizó un análisis sobre cada etapa.
También se logró entregar una visualización clara y apropiada de los resultados.
Este trabajo sirvió para crear una base de conocimiento sobre esta nueva técnica para
que pueda continuar siendo desarrollada y mejorada. Diversas mejoras potenciales fueron
identificadas y se entregaron diversas soluciones para su posterior implementación en futuras
campañas para el mejor provecho de los recursos existentes.<br>Este trabajo ha sido parcialmente financiado por Proyecto CORFO 14IDL4-300327 EXPLORACIÓN MINERA POR TOMOGRAFÍA SÍSMICA

Full textAbstract:
For decades, unresolved conflicts have negatively influenced the general public through increased violence, overwhelming the judicial system. A literature review suggested that between 15% and 20% of conflicts result in an impasse. This study was designed to understand how the implementation and application of the transformative meditation technique (TMT) is used to resolve conflicts. The purpose of this qualitative case study was to investigate the interpretation and implementation of TMT. This qualitative case study was grounded in the conceptual framework of interest-based negotiation (IBN) principles. The research questions focused on mediators' perceptions, interpretations, and depth of knowledge, as well as the effectiveness of the transformative mediation technique (TMT) as an improvement over evaluative or facilitative techniques in resolving conflicts and reducing impasses. Twenty face-to-face interviews were conducted with purposefully selected mediators. Data were coded and analyzed to identify recurring themes: interests, needs, responsibility, relationship, empowerment, problem solving, and negotiation. The findings of the data analysis revealed that mediators were familiar with TMT; interpretation and implementation varied with mediator style. Moreover, most mediators were not highly educated in TMT. In addition, it was found that simply having knowledge of TMT did not prepare mediators to apply the technique appropriately. Mediators were more attracted to the hybrid transformative mediation technique (HTMT). This study has the potential to create positive social change by reducing the number of litigations, giving relief to the overburdened justice system, and thus decreasing the use of limited courts resources.

Performance/dependability evaluation via modeling results in fast and economic system development. Traditionally, simulations have been used to evaluate realistic systems but do not yield exact results. Analytic solution methods can yield exact results, but can suffer from the state-space explosion problem. A reduced base model construction technique for stochastic activity networks, which exploits the net structure to generate a considerably reduced state-space for systems with high degree of replication, has been developed. An implementation of this technique shows that it can be successfully used for efficiently evaluating realistic systems, previously considered unsolvable by traditional stochastic Petri net methods.

Full textAbstract:
碩士<br>朝陽科技大學<br>資訊管理系<br>102<br>Digital video is messages that digitally recorded video data. Video matting technique is mainly used for post-production of movie film and image synthesis. In the past, a lot of manpower is needed so that the cost is expensive for the extraction of the foreground object, especially in the edge portion. If you want to process the hair or complex edge area perfectly, it will have a considerable difficulty. This issue had been discussed in detail in the paper titled “A Closed-Form Solution to Natural Image Matting”, Levin 2008 [1]. As for this technical report, it is the implementation of the Levin’s paper. We explore techniques of the paper to design an operating software that it can be able to perform video matting simply and conveniently.
In the paper of “A Closed-Form Solution to Natural Image Matting”, the method based on Closed-Form Matting framework is used to estimate α value for each pixel, and then it is extended to video matting. In the experiment, it had been proved that the method can accurately remove foreground objects effectively. However, if you not only want to achieve efficiency but also to show the effect of the technique perfectly, to have a good operating tool is inevitable. As our results show, the system that technical report implemented not only can be used on different images, but also it can accurately estimate the alpha matte of the frames of the video. Moreover, the synthesized images or videos can reach a certain quality.

碩士<br>國立中正大學<br>電機工程研究所<br>106<br>Design and implementation of printed-circuit board electromagnetic surfaces is presented in this thesis. The microstrip electromagnetic elements with delay lines possessing wide adjustable reflection phase range are utilized to improve the design flexibility of the electromagnetic surfaces. The characteristics of the adopted electromagnetic element are analyzed while a linear and smooth reflection phase response covering about 600∘is obtained by adjusting the length of the delay lines attached on the element. Based on the theory of the reflectarray, the phase distribution of elements can be acquired and the required reflection phase shift can be fulfilled by changing the physical delay lines there by achieving the beam-forming capability.
An offset-fed electromagnetic surface with area of 50×50 square centimeter and was implemented. The beamforming capability of the electromagnetic surfaces has been verified by theory and measurements. According to the design considerations discussed in this thesis, the gain of the electromagnetic surface can be predicted and has satisfactory agreement with the measured results. Finally, the designed electromagnetic surfaces are placed at appropriate location to enhance the receiving signal quality of non-light-of-sight communication. Measurements of the direction of the reflected beam correlate well with theoretical expectation and the error vector magnitude is about 6.4 percent.
The other topic of this thesis is presenting an electronically tunable element using varactor diodes. The reflection phase responses of the element are acquired both from the equivalent-circuit model and full-wave electromagnetic simulator. The two simulated results show satisfactory agreement with the measurement. The designed electromagnetically tunable element with over 220∘of phase agility at center frequency 10 GHz.

Falling accidents become one of the major causes of injuries for the elderly. Therefore, how to detect and get appropriate rapid first-aid medical care is very important when elderly falling accidents occurred. There have been already various kinds of mobility aids provided to the elderly for their assistance needs in daily moving. For the purpose of convenience and portability, most of the elderly will choose a cane to assist their daily moving. This paper proposes an acceleration detection device added to an elderly cane. This device is implemented using Android embedded technology. A falling model is setup through learning and summarizing the moving acceleration curves in the different behaviors, like normal walking, cane throws, cane slips, and various kinds of falling, and so on, of using a cane. It can be further applied to detect accidental fallings and then automatically raise an alarm upon these emergency situations. Therefore, the proposed system could successfully enhance more helpful safety functions to an elderly cane.

碩士<br>國立中央大學<br>太空科學研究所<br>102<br>In this study, a single-input multi–output (SIMO) scheme is proposed to improve the azimuth resolution of conventional single-input single-output (SISO) Synthetic Aperture Radar (SAR) based on Displaced Phase Centre Antenna (DPCA) technique and Multi-Channel Reconstruction Algorithm (MCRA).
A DPCA SAR scheme can acquire more than one azimuth sampling during one pulse repeated period. Therefore, the required Pulse Repetition Frequency (PRF) can be greatly decreased while enabling a wider imaging swath. A Multi-Channel Reconstruction Algorithm (MCRA) is applied to recover the uniformity of non-uniform sampling signal resulted from the varieties of the PRF. We adopt a three-channel DPCA SAR system for experiments and several simulations are performed to verify the proposed reconstruction algorithm.
The images performance of the proposed method has been compared with conventional SAR. The experimental results show the advances of the SIMO-based SAR with wider swath under the same azimuth resolution.

Full textAbstract:
碩士<br>義守大學<br>資訊工程學系碩士在職專班<br>99<br>The development of software is highly labor- and money-consuming. Software is the crystallization of human wisdom, and also a kind of special commodity. If its core technology is cracked, its developer will face a great loss. Therefore, software protection becomes very important. With the increasing publication of software in the form of sharing in the network, the techniques of software protection and data encryption loom more and more prominent. For that reason, besides legal restrictions, software developers always put the focus of their concerns on how to intensify the protection of their own software, rather than how to stop others’ illegal copying.
The current protection techniques can be classified into two categories: hardware and software encryptions. The former is safer but costly and inflexible while the latter is economic and convenient. Consequently, software shell encryption becomes the current mainstream of packing techniques. This study aims to beef up the difficulty in cracking software by even tighter combination between the protection program and original function program of the software. The intensified difficulty is going to disable anyone from cracking software unless the cracker has ability to rebuild the software. For this purpose, the study looks into characteristics of the unpacking techniques that are currently prevalent, and hereby selects the tested packing programs together with corresponding software in order to analyze and find out the more reasonable methods by which protection programs are uneasy to be cracked.
On the basis of extensive acknowledgement that traditional packing software are not strong in their protection ability, this study designs a kind of simple packing tool by adopting a modular structure. In the light of the particularities of resources block in the Portable Executable files, the study analyzes the directory and data of resources respectively. At the same time, in order to improve safety, the study transforms the original input table if necessary, and designs a corresponding structure. Starting from the angle of Anti bugging technique, this study deeply analyzes the means to protect programs from being cracked as more reasonable, which provides corresponding counter-measures adopted in following program design.
In the end, this study analyzes the existing problems of the packing tool, and suggests some main means to improve the current safety of applied software.

Full textAbstract:
碩士<br>中華大學<br>電機工程學系<br>107<br>This thesis is focuses on the NB-IoT(Narrowband Internet of Things) SoC(System on the Chip) testing specifications implemented by ATE (Automatic Testing Equipment) for fast and complete verification of all chip functions in mass production.
ATE measurement is different from the measurement of general laboratory instruments. In the laboratory, several different instruments need to be pieced together to measure a single function. The ATE can quickly and consistently integrate digital, analog and RF signals through the Load Board to perform all functional measurements of all the different blocks in the device at one time. With the excellent MSE (Multi-Site Efficiency) feature of the ATE, the cost of the test is greatly reduced.
ADVANTEST V93000 Port Scale RF tester were used to automatic testing mass production and classification and have shown good testing performance for all NB-IoT RF specifications including Power, EVM, Gain, Noise Figure, I/Q Mismatch and IIP3.
Keywords: Narrowband IoT, ATE, Mass Production.

The physiological parameters are usually transmitted by using the infrared LED or RF in the biotechnology system. In this thesis, we transmit the records by using analog communication technique.
Besides mixers for modulation needed, we utilize a PLL to make carrier more stable in transmitter. On the other hand, we adopt 6th stage Gm-C BPF for channel selector and 2nd stage active RC LPF for demodulation in receiver. The PLL in receiver is to lock shifted phase in transmission path.
The specifications of our designed system are: 1. Modulation method: Amplitude Modulation, 2. Operation frequency: 20MHz ~100MHz 3. Biosignal amplitude: 1~10 mV. At last, we design the system on TSMC0.35um 2P4M fabrication. If the transmitter and receiver chips would be realized successfully, the system must provide much contribution to mankind health.

Full textAbstract:
碩士<br>中華大學<br>營建管理研究所<br>95<br>When construction projects in Taiwan suffer schedule delay problems, there are no standardized acceptable analysis methods for resolving the problems. In general, the manipulation principle for delay analysis in Taiwan is to accumulate the impacted days of delay events on critical path, and then make compensation or fine for such measured delay days. Many delay analysis techniques are developed overseas for assisting in delay analysis, but these techniques are complicated in methodology and laborious in calculation. To run such analysis techniques requires skilled schedule analysis and consumes much calculation time. To cope with the complicated analyses, there is a requirement for developing a delay analysis support system with the mechanism of speedy, objective and accurate calculation model in liability distribution. The developed system will benefit in saving calculation time and in reducing calculation processes. First, this study analyzed the But-for delay analysis technique to check its logic and integrity in resolving various delay events. After incorporating a mechanism for apportioning excusable-noncompensable delays, this study proposed a modified backward-based but-for analysis model. Based on the analysis results via IDEFØ and DFD techniques, this study generated system flow and information flow for proposed system. Furthermore, this study used the Visual Basic for Application (VBA) program in Microsoft Project to develop a prototype for proposed system. Through a modified real case, the developed system can quickly calculate project total delay days and accurately responsible days for contract parties. Calculation results can be a basis for further dispute resolution.

碩士<br>國立交通大學<br>電機學院碩士在職專班電子與光電組<br>95<br>Because of development of the network and increment of the information,it is the target how to use the limited bandwidth to get satisfied quality in multimedia content. By develop new coding method and use proper quantization factor, we can meet the trade off between quality of multimedia content and the capacity of bandwidth. For JPEG and MPEG , we always compress image by block based discrete cosine transform (BDCT). However, when we reconstruct a low bit rate image, we will see the noticeable blocking artifacts . Therefore if we do post- processing in reconstructed image, we will improve the quality of human visual. The capability of multi-scale and multi-resolution of wavelet ensures that we can use the forward wavelet transform to decompose an original image into smooth and detailed subimages in different multi-resolution levels, and restore specific subimages by using the backward wavelet transform to separate defects from regular noise model. In this research we use over-complete wavelet to separate the blocking noise and the origin image . By the character of over-complete wavelet , we can judge the blocking area, and use de-noise algorithm to eliminate the blocking effect.We also implement the hardware design by FPGA ,and test the real image.

碩士<br>國立臺北科技大學<br>機電整合研究所<br>98<br>There is a recovery when using traditional method to measure the NBTI effect. The recovery will affect the degradation of pMOSFETs and consequently the estimated lifetime of the devices. The on-the-fly technique is developed to reduce the effect of recovery. Therefore, more objective and accurate value of the degradation can be obtained with the on-the-fly technique.
The purpose of the study is to carry out on-the-fly technique by using the Agilent 4156C without extra equipment and creating a program to measure and to analyze the recovery effect during and after stress.
The program is written based on the built-in IBASIC of Agilent 4156C and then it is used to measure NBTI degradation. The measured data is then compared with the value measured with traditional measurement. The results reveal that the degradation value obtained by the program is larger and closer to real degradation. The program also helps us to find bigger effect of recovery after stress, which is also considered more realistic.
Above all, the on-the-fly technique developed using IBASIC breaks the original constraint in Agilent 4156C. Therefore this technique is not only providing more realistic measurement but also reducing the cost for buying new instrument in laboratory and enhancing the efficiency of use original Agilent 4156C.

碩士<br>國立成功大學<br>電機工程學系碩博士班<br>96<br>The object of this thesis is to realize the speed control of permanent magnetic synchronous machine (PMSM) using the self-tuning fuzzy technique. The control of state variables uses three phase mathematical transformation model to decouple abc states into q-axis and d-axis variables in synchronous rotating frame for field oriented control (FOC).
Following that, we implement the algorithms of FOC, space vector pulse-width modulation (SVPWM), and speed control using the digital signal processor (DSP). Regarding to the influence of controller parameters on dynamic response of the motor speed, this thesis proposes the speed control of PMSM using self-tuning fuzzy technique. By the self-tuning technique, the on-line fuzzy logic controller (FLC) output can give better speed response under the load disturbances or variable speed commands.
Testing results show the proposed control strategy is more robust than the traditional proportional-integral control.

碩士<br>國立成功大學<br>微電子工程研究所碩博士班<br>101<br>In the case that LED light source gradually replaces traditional light source, the color temperature is arousing attention from industry. We can explore the relationships between color temperature and comfort range by analyzing the color temperature in physiological and psychological attributes. Then, apply it to different circumstances and purposes. We can see lots of LED applications for color of lighting today.
The main goal in the thesis is to research on the method of LED color mixing. Through the given single LED package specifications, including luminous flux and chromaticity coordinate, then develop an algorithm of different specifications for LED color mixing. Afterwards, put the mixing number respectively into calculation to get the mixed chromaticity coordinate. Then use the formula of chromaticity coordinate transforming into color temperature to get the final mixing color temperature. Also, we can get the respective mixing number by putting the mixing parameters into algorithm of two and three specifications for LED color mixing. It is very helpful for LED applications of color temperature in solid-state lighting.
In this essay, use the experiments of LED street lighting arrays and FRED optical simulation software respectively to verify the algorithm for LED color mixing. About the experiments of LED street lighting arrays, this part is to mix into low color temperature(3000K~4000K) and middle color temperature(4000K~5000K)by mixing numbers of 88,90,112,135.It is Measured by the Luminous Intensity Distribution Instrument assigned from CNS15233 of Bureau of Energy, Ministry of Economic Affairs. It turns out two trends: the more the mixing number is, the more the inaccuracy is. And, the higher the mixing color temperature is, the smaller the inaccuracy is. Besides, both of the inaccuracies are below the standard of 4%. Through the experiment and simulation, we can get the conclusion that LED of low color temperature (P2N) arranged in the middle resulted in smaller inaccuracy. In the end, combine the algorithm for LED color mixing and PWM dimmer controlling to propose a new method of LED color mixing.

Full textAbstract:
碩士<br>臺灣大學<br>電機工程學研究所<br>98<br>In this thesis, we implement a Design-for-Test (DfT) technique to measure the integrator leakage of ΔΣ modulator. We use Field Programmable Analog Array (FPAA) to implement the ΔΣ modulator and utilize DC voltage as the test stimulus. The integrator leakage testing method is base on integrator charging/discharging; it is an iterative three-phase approach. In phase I, the integrator is charged with a constant DC input to reach a stable, leakage-dependent voltage level. In phase II, the integrator is gradually discharged. The time of discharging is recorded and used to derive the integrator leakage. In phase III, it is determined whether a new iteration can be executed to further enhance the test accuracy.
The field programmable analog array device is based on the switched capacitor technology. It is composed of four configurable analog blocks, seven IO cells, a clock generator, and configuration interface. The basic configurable analog block is composed of two operational amplifiers, a comparator and eight capacitor arrays. Circuits are realized through manipulation of switches between various circuit components inside the configurable analog block. Using field programmable analog array to design circuit will save us a lot of time and money.
We use the field programmable analog array to design a ΔΣ modulator with tunable integrator leakage and utilize DAQ to generate the test signal and acquire the output signal from FPAA. According to the experimental result, we improve the test method to achieve better accuracy --- the maximum error is reduced from 1.89% to 1.17%.

Full textAbstract:
博士<br>國立臺灣大學<br>電子工程學研究所<br>100<br>Because of the robustness of the Particle Filter (PF) in nonlinear/non-Gaussian applications, the PF algorithm is now very widespread and has a significant impact in virtually all areas of signal and image processing concerned with Bayesian dynamical models. The PF uses samples (particles) and associated weights to represent the probability density function (PDF) of the state. The estimation of the state we are interested can be obtained with the PDF predicted by the PF.
Due to wide application of PF, it is important to make the PF algorithm feasible for practical systems. In other words, the PF algorithm should be efficient in hardware/software implementation. In this dissertation, a novel PF algorithm, multi-prediction PF (MP-PF), is proposed. The proposed MP-PF can significantly reduce the memory requirement without loss of estimation accuracy. Besides, the parallel implementation technique is a popular approach to reduce the execution time. Most operations of the PF algorithm are independent and can be executed in parallel. However, the sequential operations of PFs still limit the improvement from parallel implementation. In general, the complexity of the sequential task is proportional to the particle number. The proposed MP-PF can reduce the particle number, as well as the complexity of the sequential task. To verify the benefit of the proposed MP-PFs, we implement the proposed MP-PF on Nvidia multi-core GPUs, which has high efficiency to process many parallel local computations. For the classic BOT experiments, the maximum improvements of the proposed MP-PF are 25.1 times and 15.3 times faster than the SIR-PF with 10,000 and 20,000 particles respectively.
In addition to the development on the basic PF algorithm, this dissertation also applies the PF algorithm into the positioning system. [27] reduces the particle prediction uncertainty by using the map information, so the PF can use fewer particles. However, the strong constraints reduce the flexibility of propagation model which we need to compensate the unawareness of target''s true behavior of motion. Rather than using a simple/constrained particle transition model, this dissertation proposes a location estimation framework which integrates location constraints into particle filter, including invalid regions, walls, and turning regions for adjusting the motion model. In the proposed location-constrained PF (LC-PF), the combination of location-constrained weight updating and constrained propagation makes large accuracy improvement. Comparing with the basic PF, the LC-PF can give the error reduction around 68%.

Full textAbstract:
碩士<br>國立中央大學<br>電機工程研究所<br>93<br>OFDM technique has been widely implemented in high-speed digital communications to increase the robustness against frequency selective fading or narrowband interface. The major advantage of OFDM is the ability to enhance the basic signal using approaches that can overcome channel impairments.
In digital communication, binary information is converted by means of a modulator into a continuous-time signal which is sent over the transmission channel. A digital receiver is to extract the information sequence from a discrete signal obtained after sampling and quantizing the distorted signal presented to the demodulator. At the receiver, accurate timing recovery is critical to obtained performance close to that of the optimal receiver. Timing in a data receiver must be synchronized to the symbols of the incoming data signals.
This study considers a non-synchronized sampling scheme. The received signal is performed by a fixed sampling clock; the samples are not synchronized to the incoming data symbols. Timing adjustment is done after sampling using interpolation. Farrow structure has been commonly used to efficiently implement the Lagrange interpolation for timing adjustment.
This thesis presents the efficient implementation of the Farrow structure for cubic and quintic interpolations. Results show that the developed cubic Farrow structure achieves a hardware cost reduction by 23% from the conventional one. The design concept can be readily extended to the Farrow structures for higher order interpolations.

This paper presents a novel edge-preserving image restoring technique for interlaced video. We utilize a motion-degree detector to determine motion direction of block between the adjacent images and a scene-change detector to estimate if the main body of block moves wildly. According to detection results, we choose temporal interpolation or spatial interpolation method to restore the missing pixels. Experiment results show that the data analysis and visual effects are better than other algorithm before.
Our technique is implemented with VLSI architecture by using Verilog HDL. The system is designed with pipeline architectures to achieve better performance. We used SYNOPSYS Design Vision to synthesize the design with TSMC 0.13μm cell library. Synthesis results show that our design contains 13.3K gate counts. It operates with a clock period of 5 ns and operates at a clock rate of 200 MHz.

Non-distorted compression is utilized the encoding statistics or looking for the table to finish the purpose to compressing. But it is insufficient places to the compression on video-information.
