På Volvo Cars Corporation (VCC), är vevaxelmoment styrsignal för kalibrering av växellådan under växling. Målet med detta examensarbete är att utforma en verifieringsmetod (DVM) för vevaxelns vridmoment. Baserat på hjulet vridmoment, beräknas vevaxel momentet genom att kompensera momentförluster steg för steg. De relativa vridmoment-förlusterna ges av tidigare mätningar. Momentförlusterna klassificeras enligt olika komponenter i fordonets transmissionssystem. Vevaxelns modellerade vridmomentsignal används som referenssignal för att utvärdera prestandan hos verifieringsmetoden (Design Verification Method). Referenssignalen är certifierad inom ett visst intervall av VCC.At Volvo Cars Corporation (VCC), crankshaft torque is a control signal for calibrating the gearbox for gear shifting operations. The goal of this master thesis is to design a verification method (DVM) for crankshaft torque. Based on the wheel torque, the crankshaft torque is calculated by compensating the torque losses step by step. The relative torque loss data are provided by the previous measurements. The torque losses are classified by different components in the vehicle transmission system. The modeled crankshaft torque signal will be used as a reference signal to evaluate the performance of the Design Verification Method. The reference signal is certificated within a certain range by VCC.

Full textAbstract:
With the rise of cloud computing and the migration to web-based applications, scalable systems have become highly desirable. And while developing software is hard, designing a scalable system is even harder. The microservice architecture is an attempt to improve the scalability but may introduce additional challenges. In order to correctly implement the microservice architecture, it is important to understand how the different mechanisms used in the architecture affect the quality of the application. The purpose of this research is to show how to evaluate microservice applications and how much they can differentiate from each other. A literature study and an architectural analysis are performed by reviewing research related to web applications and microservices. Subsequently, the empirical data is collected by evaluating and comparing two different microservice applications based on their quality characteristics. The results of the literature study indicate that performance efficiency, compatibility, reliability, security, maintainability and portability are the most relevant quality characteristics of the microservice architecture. Furthermore, the architectural analysis describes how microservices affect these quality characteristics. Lastly, the evaluation showed that different approaches can significantly alter the strength of the different characteristics. For this specific comparison between the two selected applications, it was determined that the biggest differentiating factor is the asynchronous and synchronous messaging. To conclude, the results show it is possible to evaluate a microservice application by its qualities. Additionally, while microservice applications may use completely different technologies, the fundamental concept behind them remains the same. What differs is the approaches used and how they affect the quality characteristics.

Full textAbstract:
Taguchi defines quality loss as the loss imposed to the consumer for each unit of deviation from the target consumer requirements. In this thesis, the effects of inspection error and rework on quality loss are studied for a nominal-the-best type quality characteristic. The distribution of the quality characteristic in a production environment where there are inspection error and a separate rework facility is investigated. 100 % inspection policy is considered. After deriving the mean and variance of the resulting distribution of the quality characteristic, the true and simulated quality loss values for a number of scenarios are calculated. Furthermore, effects of deviation of the process mean from the target and variance of the rework are studied besides inspection error and process capability through a full factor factorial experimental design. Results are discussed for possible uses as quality improvement project selection criteria.

Full textAbstract:
Most of the process measurement studies are related with time and cost based
models. Although quality is the other conventional aspect, there are no widely used
models for measuring the process quality in the literature. In order to provide
complementary information about the quality, a process quality measurement model
has been chosen to be developed and the studies about process characteristics have
been searched in the scope of the thesis. Moreover, by utilizing the similarities
between process and software, the studies in software quality have been investigated.
In the light of the researches, a model is built on the basis of ISO/IEC 9126 Software
Product Quality Model. Some of the quality attributes are redefined in the model
according to the process characteristics. In addition, new attributes unique only to the
process are developed. A case study is performed and its results discussed from
different perspectives of applicability, understandability and suitability.

Thompson, John D. "The role of the free-response receiver operating characteristic method for dose and image quality optimisation." Thesis, University of Salford, 2015. http://usir.salford.ac.uk/33459/.
Full textAbstract:
This thesis describes the value of the free-response receiver operating characteristic (FROC) paradigm for dose and image quality optimisation in a niche area of imaging. The empirical works discussed in this thesis focus on the diagnostic value of the low-resolution computed tomography (CT) images acquired for attenuation correction (AC) – a process primarily used to correct for photon attenuation with images produced merely as a consequence of the exposure. The potential discovery of incidental findings on these images was investigated. The observers taking part in the empirical studies were generally lacking in significant experience of interpreting CT images. As a consequence it was also deemed valuable to investigate the value of the novice observer in free-response studies. A further methodological consideration for studies of this kind is consistent and reliable image display and FROC data collection. Prototype software, ROCView, was designed and developed to make this an easy process and the key functionality and impact is analysed here. In addition to the empirical works, two review papers, aimed at the technologists and radiographers performing low-resolution CT for AC, are summarised. They explain the value of the FROC paradigm and the jackkinfe alternative FROC (JAFROC) analysis method to a wide audience in nuclear medicine.

Full textAbstract:
Maintaining or even improving image quality while lowering patient dose is always the desire in clinical computed tomography (CT) imaging. Iterative reconstruction (IR) algorithms have been designed to allow for a reduced dose while maintaining or even improving an image. However, we have previously shown that the dose-saving capabilities allowed with IR are different for different clinical tasks. The channelized scanning linear observer (CSLO) was applied to study clinical tasks that combine detection and estimation when assessing CT image data. The purpose of this work is to illustrate the importance of task complexity when assessing dose savings and to move toward more realistic tasks when performing these types of studies. Human-observer validation of these methods will take place in a future publication. Low-contrast objects embedded in body-size phantoms were imaged multiple times and reconstructed by filtered back projection (FBP) and an IR algorithm. The task was to detect, localize, and estimate the size and contrast of low-contrast objects in the phantom. Independent signal-present and signal-absent regions of interest cropped from images were channelized by the dense-difference of Gauss channels for CSLO training and testing. Estimation receiver operating characteristic (EROC) curves and the areas under EROC curves (EAUC) were calculated by CSLO as the figure of merit. The one-shot method was used to compute the variance of the EAUC values. Results suggest that the IR algorithm studied in this work could efficiently reduce the dose by similar to 50% while maintaining an image quality comparable to conventional FBP reconstruction warranting further investigation using real patient data.

Full textAbstract:
The paucity of research in performance management of call centres is evident from the confusion regarding what is desired by the customer from this mode of service. A variety of recommendations have been put forward in various studies, but a holistic perspective on what constitutes quality is still lacking. This research is an attempt to investigate key factors which determine performance measurement in technology mediated call centre environment with the help of a conceptual model. A combination of qualitative and quantitative approach has been used to develop and test survey items on direct customer response. The case call centres are selected on the basis of service classification model proposed in the study. A conceptual model is formulated based on preliminary literature review. Qualitative stage has involved semi-structured interviews with senior executives, followed by focus groups conducted with call centre agents. The analysis of survey developed hence has been performed using methods of quantitative data analysis. To the best of our knowledge this study is the first to apply communication theory to an exploration of relational (socio-emotional) aspect in call centres service performance. Identifying the association formed between the customer and service provider in its discreet sociological context, it is argued here that being susceptible to limitations attributed to technology-mediated communication channels, call centres are a unique context of study and therefore performance evaluation should take account of this inherent unique.

Full textAbstract:
Eulerian chemical transport models are extensively used to steer environmental policy, forecast air quality and study atmospheric processes. However, the ability of these models to simulate concentrated atmospheric plumes, including fire-related smoke, may be limited. Wildland fires are important sources of air pollutants and can significantly affect air quality. Emissions released in wildfires and prescribed burns have been known to substantially increase the air pollution burden at urban locations across large regions. Air quality forecasts generated with numerical models can provide valuable information to environmental regulators and land managers about the potential impacts of fires. Eulerian models present an attractive framework to simulate the transport and transformation of fire emissions. Still, the limitations inherent to chemical transport models when applied to replicate smoke plumes must be identified and well understood to adequately interpret results and further improve the models' predictive skills. Here, a modeling framework centered on the Community Multiscale Air Quality modeling system (CMAQ) is used to simulate several fire episodes that occurred in the Southeastern U.S. and investigate the sensitivity of fine particulate matter concentration predictions to various model inputs and parameters. Significant sources of uncertainty in the model are identified and discussed, including the spatiotemporal allocation of fire emissions and meteorological drivers. In addition, special attention is given to model grid resolution. Adaptive grid modeling is explored as a strategy to simulate fire-related plumes. An adaptive version of CMAQ, capable of dynamically restructuring the grid on which solution fields are estimated and providing refinement at the regions where accuracy is most dependent on resolution, is presented. The fully adaptive three-dimensional modeling technique can be applied to reach unprecedented levels of grid resolution and provide insight into plume dynamics unattainable with static grid models. Through this work the capability of current chemical transport models to replicate fire-related air quality impacts is evaluated, key research needs to achieve effective simulations are identified, and numerical tools designed to improve model performance are developed.

Full textAbstract:
För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras. Produktionsteknisk mätteknik och resultat från utförda mätningar används sedan som indata för statistisk processtyrning och övervakning av produktionsprocesser. Syftet med vår forskning har varit att först ta fram en nulägesbild av mätteknisk beredning inom fordons- och flygindustrin och utifrån den identifiera framtida trender med behovsanalys och gap. Utifrån analysen har vi sedan utforskat och utvecklat en modell och metodik för mätteknisk mät- och styrbarhetsberedning. I denna licentiat avhandling har vi utforskat området geometrisk och dimensionell mät- och styrbarhetsberedning (GMCP - Geometrical and dimensional Measurement and Controllability Planning). Vi presenterar en nulägesanalys av området och vi presenterar en teori med modell och ramverk för GMCP. Vidare har vi utforskat en metodik och verktyg benämnd kvalitetssäkringsmatris (QAM - Quality Assurance Matrix) och som vi lyfter fram i denna avhandling. I slutet av avhandlingen presenteras och diskuteras dem hittills uppnådda resultaten från forskningen och i det sista kapitlet dras slutsatser och den fortsatta forskningen inom ”SIMET-GICP” projektet presenteras.In order to ensure final product quality on machined components, manufacturing enterprises must measure and inspect the geometrical and dimensional characteristics of components before they go into higher-value assemblies. Commonly, the geometrical and dimensional measurement and inspection occurs every time at machine tool set-up, when a line is restarted or if the production process is changed. Production metrology and results from production measurements is used as input data for statistical process control and monitoring of production processes. The purpose of our research has been to firstly perform a state of the art analysis in the area of measurement planning applied in the automotive and aerospace industry. The output from the state of the art study has then been used to identify future trends and needs including a gap analysis. Then we used the analysis to explore and develop a model and methodology for measurement and controllability planning. In this licentiate thesis we have explored the area of GMCP (Geometrical and dimensional Measurement and Controllability Planning). As a major result in this thesis a state of the art survey on GMCP is presented. Based on the state of the art study a theory and model framework for GMCP has been explored and a methodology and tool called QAM (Quality Assurance Matrix) is highlighted in this thesis. In the end of the thesis we present and discuss the present research results we have accomplished and in the final chapter we draw conclusions and outline the continued research within the SIMET-GICP project.

Full textAbstract:
Quantify the magnitude, sources and distribution of variation in fruit quality traits within kiwifruit populations and identify opportunities for the management of this variation. Near-infrared (NIR) grading was used as a tool for monitoring fruit quality, and measurements combined with orchard/vine information to investigate opportunities for the management of the variation in fruit quality traits with a particular focus on fruit DM. NIR enabled non-destructive assessment of the quality characteristics of individual fruit from 96 commercial orchards, comprising 550 fruit-lines, across four consecutive seasons, resulting in a dataset of measurements made on 146.7 million individual fruit. The distribution of quality traits within fruit populations and the relationships between quality traits were examined. The spatial component of variation in fruit quality was investigated to assess the potential for zonal management practices. Finally, the effects of growth temperatures on fruit quality were studied. Significant variation in fruit quality was observed between-seasons, between-orchards, and between-vines within an orchard. From comparison of CVs between quality traits, cropload was more variable than fruit weight which varied more than fruit DM, independent of the production scale considered (between-orchard or between-vine). Across a hierarchy of fruit populations (individual vine, fruit-line and orchard), the majority of fruit quality distributions demonstrated significant deviations from normality. However, departures from normality can be tolerated for estimation of the proportion of fruit with specific quality criteria. The sources of variation in fruit weight and DM populations were investigated at both a between-orchard scale and a within-orchard scale. Between-orchard variation was significant, however, the majority of variation occurred within-fruitlines, within-orchards and within seasons. The within-fruitline component of variation was investigated separately. Both between-vine and within-vine variation were significant, but within-vine variation was dominant. The focus of management should be on reducing variation occurring within-fruitlines within-orchards, which is largely attributable to variation occurring within the individual vine. Higher croploads per vine have negative consequences for fruit weight but variable effects on DM. Increasing croploads reduce both FW and DW allocations for each fruit, therefore the effect of cropload on DM is dependent on the relative reductions in FW and DW. The DW allocations to fruit are not limited by DW production, at least up to the croploads observed in this study (≤65 fruit m-2). The potential for zonal management was investigated. Variation in fruit quality characteristics between-orchards across the Te Puke growing region, and between-vines within an individual orchard area were investigated using geostatistics. A spatial component to variation was identified both between-orchard and between-vine. However, the effect of spatial variation was diluted by that of non-spatial variation and therefore, zonation between orchards or between areas within-orchards should not be where the effort in managing variation is concentrated. Orchard altitude correlated with some aspects of fruit quality. Mean fruit weight declined 0.5g and within-orchard variation in fruit weight declined 0.25 units with a 25m increase in orchard altitude. Mean fruit DM was independent of orchard altitude and within-orchard variability in DM declined 0.023 units per 25m increase in orchard altitude. Differences in orchard altitude equated with differences in growth temperatures. Warm spring and cool summer temperatures favour the growth of high DM fruit. The effects of spring temperatures on canopy development and maturation were investigated to elucidate potential physiological mechanisms for temperatures effects on fruit growth. Higher spring growth temperatures increased the rate of total leaf area development and promoted development of leaf photosynthesis. Higher spring growth temperatures favoured a more positive carbon balance, which has beneficial effects on the development of fruit quality characteristics. Post-harvest, the traditional practice of grading fruit into count sizes generally also segregates for DM, and large count size fruit will often have higher DM than small sized fruit. Between fruit populations, a positive correlation was identified between fruit DM and acidity; therefore, segregation of the inventory by DM will also segregate for acidity. High DM fruit are also more acidic with a higher, more favourable brix/acid ratio when ripe. It is recommended that fruit DM status be managed in the inventory, not by maturity area as is the current practice, but by groups of similar count sizes within maturity areas.

Full textAbstract:
Dans le cadre du travail de recherche réalisé dans cette thèse, la réflexion porte sur les caractéristiques qualitatives des normes juridiques sous des dimensions à la fois théorique, pratique et comparée. L’intérêt majeur de ce travail est de s’interroger sur l’appréhension de la notion de qualité, qui intéresse beaucoup la doctrine, et est devenue une préoccupation croissante de nombreux systèmes juridiques alors même que les contours, et même le contenu, de la notion de qualité des normes restent flou. Le souci d’améliorer la qualité de la législation (au sens large du terme) répond à deux problèmes principaux dans la pratique et la théorie : sur le plan pratique, les défauts formels et substantiels de certaines normes les rendent inaptes à l’accomplissement de leur fonction principale, soit la régulation des relations sociales ; sur le plan théorique, l’exigence de bonne qualité des normes est une condition essentielle dans un état de droit qui permet aux citoyens de savoir à quoi s’attendre de leur gouvernement et à faire des investissements en conséquence (principes de prévisibilité et de sécurité juridique). En dehors de ces caractéristiques formelles ont été examinées les caractéristiques matérielles qui jouent un rôle important quant à l’acceptation des normes juridiques par les citoyens. La démarche adoptée dans le présent travail de recherche ne se limite pas à l’étude de l’élaboration d’une norme juridique, mais porte également sur l’exécution, l’interprétation et l’attitude des juges face aux normes. Toutefois, nous avons dépassé les études déjà réalisées, et nous avons examiné aussi la constitution et les actes administratifsAs part of the research work carried out in this thesis, reflection focuses on the qualitative characteristics of legal norms in terms of theoretical, practical and comparative dimensions. The main interest of this work is to question the apprehension of the notion of quality, which is of great interest to doctrine, and has become a growing preoccupation of many legal systems, even though, the contours, and even the content, the notion of quality standards remain unclear. The concern to improve the quality of legislation (in the broad sense of the term) addresses two main problems in practice and theory: in practice, the formal and substantive defects of certain norms render them unfit for the accomplishment of their main function,namely the regulation of social relations; on the theoretical level, the requirement of good quality of laws is an essential condition of the rule of law that allows citizens to know what to expect from their government and to make investments accordingly (principles of predictability and certainty). Apart from these formal characteristics were examined the material characteristics that play an important role in the acceptance of legal norms by the citizens. This implies the requirement of "rationality" and the "justice" in laws. The approach adopted in this research is not limited to the study of the development of a legal norm but also to the execution, interpretation and attitudes of judges in dealing with the legal norms. However, we have gone beyond the studies already carried out, and we have also examined the constitution and the administrative acts

Full textAbstract:
Engineering problems often involve many conflicting quality characteristics that must be optimized simultaneously. Engineers are required to select suitable design parameter values which provide better trade-off among all quality characteristics. Multiresponse optimization is one of the most essential tools for solving engineering problems involving multiple quality characteristics. Optimizing several quality characteristics when the quality characteristics are correlated makes the optimization process more complex. The aim of this research is to evaluate the performance of several existing multiresponse
optimization methods and investigate their capabilities in dealing with correlated quality characteristics. This study also investigates the impact of uncertainty in terms of input parameter selection. A new multi-response optimization approach has been proposed for solving correlated quality characteristics. The proposed approach is compared with the existing methods and found more robust in terms dealing with
uncertainty in target selection. The comparative study and application of the proposed approach is demonstrated by considering two examples from the literature having correlated quality characteristics.

This research examines Hemodialysis patients' psycho-social characteristics and predictors of quality of life and compliance at a small rural hospital. Sixty-four patients from the hemodialysis unit at Renfrew Victoria Hospital in Renfrew, Ontario, and a satellite unit at St. Francis Memorial Hospital in Barry's Bay, Ontario, were assessed using the Social Work Patient Profile, Perceived Quality of Life and Compliance Indices. Bivariate correlation and multiple regressions were conducted on psychosocial, physical and mental health variables to determine if they correlated, and could be predictors of, social worker and nurses' perceptions of patients' quality of life and compliance.Findings support multiple correlations between variables. Younger age, recreation, family support, self driving to dialysis, dementia, diabetes as the cause of chronic kidney failure (CKF), and other as the cause of CKF were significant individual predictors of social work quality of life score. Significant individual predictors for the nurses' quality of life scores were dementia, glomeruloneph, compliance, level of education, and polycystic kidney disease as the cause of CKF. The statistically significant risk factors for nurses' quality of life were lower levels of education and dementia. The four psychosocial variables that predicted compliance to treatment, suggested that there was increased compliance for patients who had recreation and family support, and increased risk factors with age and lower levels of education.

Part- baked technology has helped bakery industry in many ways because part-baked breads are more convenient to storage and transport. Also, customers spend less time obtaining a fresh-baked bread in bake shops or home. Even more, part-baked technology plays a role in prolonging shelf-life of breads. In order to maintain bread quality, part-baked breads usually go with frozen storage. However, the volume of part-baked breads will decrease and the hardness will increase during storage. Spoilage caused by microbial contamination is also a serious problem of a thawed part-baked bread since the water content is higher than traditional breads. Therefore, many researches use sourdough as a material of part-baked bread to improve the bread quality and inhibit microbial growth. In this research, there are five categories of samples called regular baked bread(RBB), part-baked bread(PBB), full-baked bread(FBB), commercial made sourdough part-baked bread(CMSPBB), and commercial made sourdough full-baked bread(CMSFBB). The purpose is to investigate characteristics of samples which underwent 3 days of ambient temperature storage or 8 weeks of frozen storage. Analyze whether the utilization of part-baked technology is benefit to bread quality or not, and discover methods to modify full-baking in order to improve appearance quality of full-baked bread. The results of this research indicates that the hardness of breads increased more slowly and water content varied more slightly during frozen storage than ambient temperature storage. However, there were still a significant difference after 4 weeks of frozen storage. Whether the samples underwent frozen storage or ambient temperature storage, full-baked breads were softer than regular braked breads. This is associated with the melting of starch granules during full-baking. It''s been reported that the process of starch retrogradation and bread firming can be reversed during full-baking. Concerning volume collapse of full-baked bread which underwent frozen storage, it can be improved by sourdough or modified full-baking methods including absorption method and high vapor method. The results showed that high vapor method is a better way to improve appearance quality between two modified full-baking methods.

The alluvial fan of Jhuoshuei River in central Taiwan is a known recharged area with adequate groundwater. It is a serious issue that groundwater could be pumped to make up the shortfall, maybe it is the reason why groundwater quality became worse recently. Three approaches to investigate ground water quality in central Taiwan have been applied in order to further establish the index of water quality. First, we have analyzed groundwater quality in central Taiwan area by factor analysis, the data showed that salinization factor could be the major factor. And other factors include nitrogen pollution factor, organic pollution factor and mineral factor. Second, the ions-related data showed that groundwater quality is fine. The most classified type of Stiff diagram is a combination of calcium ion and hydrogen carbonate, the next is a combination of calcium ion and sulfate; Piper diagrams has showed the most type is Type-I, the next is Type-II. Results of some monitor wells in coasting area of Miao-li, Chang-hwa and Yun-lin have showed that salinization may be caused by sea water. Third, regression data of ion strength, conductivity and total dissolved solids (TDS) seems the same as reference. The ratio of TDS to conductivity is 0.69 ± 0.11, it could present the characteristics of groundwater quality in central Taiwan. Overall speaking, groundwater quality in central Taiwan is quite good except for the salinization of groundwater in some coasting area. We suggest that the administrative agency has to keep monitoring for a long term. Eventually, representative groundwater pollution factors found from this study could provide as a reference for the pollution prevention and control of groundwater.

Financial reports have been the main resource for investors to know the operations of a corporation. After the scandal like Enron and WorldCom, the credibility of accountants and the reliability of financial reports are questioned widely. This study is try to find out that is there a relationship between accounting quality and corporation characteristic, and if the relationship does exist, what’s the direction of it. The sampled companies are selected from the listed companies in Taiwan Stock Exchange.Among the 510 samples, 150 companies are classified as good accounting information quality, the other 360 with poor accounting quality when logistic regression is undertaken. They areclassified accordind to the Predictive Value, Feedback Value and Timeliness of their accounting information. Wilcoxon test is performed to find out that is there siginificantly different corporation characteristics among the sampled companies divided into 3 groups with accounting information quality in different levels. And logistic stepwise regression is used to clarify the direction of the relationship. The result is as followed: 1. Companies with different accounting information quality are siginificantly different in profitabiliy, debt degree, company value and dividend policy, but not siginificant in equity structure when Wilcoxon test is performed. But when logistic stepwise regression is used, companies with good or poor accounting information quality are not siginificantly different in all 5 aspects. 2. The accounting information quality is not siginificantly different between electronic and non- electronic companies. 3. It is better to measure accounting information quality by taking into consideration of Predictive Value, Feedback Value and Timeliness, instead of Predictive Value and Timeliness only.

Process capability indices (PCIs) are an effective and easy–to–use approach for measuring the quality level of products in the manufacturing industry. However, using a single PCI cannot effectively reveal the causes of deficient quality characteristics in the manufacturing process. On the other hand, some multi–quality characteristic analysis charts (MQCACs) combining two or more PCIs have been proposed to overcome the problem products with two or more different types of quality characteristics. However, if quality managers use these existing MQCACs to evaluate whether the quality capability of a product meets the acceptance standard, the numerical analysis and calculation of the PCIs will be quite complex, which will directly affect the outcome of the analysis and entail a greater expenditure of time, cost and manpower. Also, these existing MQCACs cannot be useful in identifying problems with all substandard quality characteristics in larger–the–better and smaller–the–better situations due to process shift and/or variability. In practice, manufacturers should consider how to prioritize improvements that need to be made in all substandard quality characteristics in light of resource requirements, the potential for performance improvements and the uncertainty represented in decision data. Therefore, a key issue faced by the manufacturing industry is determining how to measure single or multiple quality characteristics and prioritize improvements to be made to all substandard quality characteristics of a product with respect to resource requirements and performance improvement potential. This dissertation is organized into five chapters in order to analyze and discuss the abovementioned issues. Chapter one covers the motivation, objectives, framework of this dissertation, and a literature review on PCIs. Chapter 2 illustrates how to combine the process capability index Cpm, minimum individual quality capability index C0, accuracy A and precision P to construct a quality capability analysis chart (QCAC). From the scatter diagram of related data on the QCAC, we can find all of the substandard quality characteristics, and identify the causes of all the substandard quality characteristics in a product owing to process shift and/or variability. Meanwhile, the values of the discrimination distance (DD) of all the substandard quality characteristics are calculated. Quality managers can use the values of the DD to rank all the substandard quality characteristics slated for improvement in order of priority if the total budget for all the substandard quality characteristics improvements is limited. Chapter 3 adds to the QCAC in Chapter 2 with the concept of six sigma to construct a new QCAC. Next, the new QCAC is tailored to combine entropy and technique for order preference by similarity to ideal solution (TOPSIS) methods into a QCAC–Entropy–TOPSIS approach. Quality managers can categorically prioritize improvement options for all substandard quality characteristics with respect to resource requirements, and consider the potential for performance improvements. Chapter 4 first uses the change–of–variable technique to transfer all of the sample data of nominal–the–best, larger–the–better and smaller–the–better quality characteristics into new evaluation data. Meanwhile, an MQCAC can be established as a powerful tool for finding all substandard quality characteristics of a product. Next, a novel hybrid method is presented that integrates a new MQCAC and a fuzzy technique for order preference by similarity to ideal solution (fuzzy TOPSIS). Quality managers can clearly prioritize improvement options for all substandard nominal–the–best, larger–the–better and smaller–the–better quality characteristics with respect to resource requirements and performance improvement potential under a fuzzy environment. Finally, Chapter 5 provides a summary of the main findings and conclusions of this dissertation, and offers suggestions for the direction of future work.

Since underground car parks are mostly located in enclosed spaces, lots of high polluting behaviors do happen there, such as starting and warming the engine, climbing or descending on the trail, and low speed cruising while looking for a vacant seat, and so on. The pollutants from motorcycle and automobiles are uneasy to clean up, and could deteriorate the air quality. In the current study, information regarding the physical size, volume, plane layout, traffic loading and venting facilities in the underground car parks of the gymnasium (GYM) and the business department building (BDB) of Feng Chia University were collected. Field survey on air pollutants (CO SO2 O3 TSP PM10 and PAHs ) with hourly traffic flow monitoring were proceeded, and afterwards the characteristics of the indoor air quality were analyzed. The results showed that both of the air quality and the air changes rate per hour （ACH） in the underground car parks of the GYM and the BDB of Feng Chia University all met the required regulations. The peak levels of the measured air pollutants in each underground car park occurred in around 3 p.m. and 5 p.m., which were coincident whit the activity time schedule of students. In general, indoor air pollution increased with the increasing number of motor vehicles entering/leaving the park. The air quality, except for SO2 and PAHs, in the car and motorcycle parks of the GYM were more deteriorating than those in the BDB, and indoor air quality in vacation days were better than the regular school days. In addition, the indoor air quality, except for TSP, in motorcycle park were more deteriorating than the car park. For the motorcycle park in the GYM, the winter time air pollution levels were higher than those in summer seasons. Finally, the assessment using CO as an air-traffic indicator showed that the air quality of motorcycle and car parks in the BDB were better than those in the GYM. The ventilation system in the BDB car parks had an obvious cleansing effect, while the ventilation system in the GYM car park did not function significantly.

Power quality has attracted considerable attentions from utilities and customers due to the popular uses of the sensitive electronic equipment. Harmonics, voltage swell, voltage sag, and power interruption could downgrade the service quality. Harmonic currents injected by non-linear loads throughout the network could degrade the quality of services to sensitive high-tech customers such as the science park of Xin-Zhu and Tai-Nan in Taiwan. In recent years, massive rapid transit system (MRT) and high speed railway (HSR) have been rapidly developed, with the applications of wide-spread semi-conductor technologies in the auto-traction system. Swell and sag could occur from thundering, capacitor switching, motor starting, nearby circuit faults, or artificial calamity, and could also attribute to the power interruption. To ensure the power quality, harmonic and voltage disturbances detection becomes important. Fourier transformation is used to analyze distorted waves in the frequency domain, with low-pass filter used to eliminate the fundamental component, and then characteristic harmonics can be detected. The complicated process is difficult to operate in real-time. The method-based processing model with physical harmonic data is needed to simplify the processing architecture. The thesis proposes to use wavelet transformation (WT) and probabilistic neural network (PNN) for power quality and characteristic harmonics detection. Wavelet-probabilistic network (WPN) is first used to extract distorted waves. PNN based processing model will then analyze the harmonic components. Computer simulation shows a simplified model to shorten the processing time in this study.

The objective of this study was to investigate the characteristics of air quality of traffic tunnels in Kaohsiung City. Air pollutants were sampled and analyzed at six traffic tunnels. Meanwhile, the number and velocity of vehicles passing tunnels were monitored. In addition , the pollution reduction and prevention strategies were proposed in the study. The air pollutants sampled and analyzed in the investigation included VOCs, TSP, PM10, CO, NOx, THC, and metals.Research results indicated that higher concentrations of CO were observed in the motorcycle-only tunnels and higher concentrations of NOx, on the other hand, were detected in the automobile-only tunnels. Therefore, CO can be used as an indicated pollution index of motorcycle-only tunnels while NOx can be used as an indicated pollutant index of automobile-only tunnels. The value of NO/NOX greater than 0.6 for all tunnels indicated that NO did not react with O2 to form NO2 completely and the NOX remained the primary pollutants of NOX.The study applied emission factor to estimate the amount of NOX, CO, and THC emitted from vehicles in traffic tunnels. Meanwhile, the measured concentration of air pollutants and the amount usually higher air pollutants estimated from emission factor and traffic flow were compared. The concentrations of an pollutants were inside longer tunnels resulting from accumulation. Besides, higher concentrations of air pollutants detected in the down wind of tunnels indicated that piston effect played an important role on the dispersion of air pollutants inside traffic tunnels.The value of NMHC/THC ranged from 0.53 to 0.91. NMHC was mainly emitted from exhaust gas and some from the vaporization of gasoline. Major VOCs detected in traffic tunnels included benzene, toluene, xylene, ethyl benzene, and styrene VOCs were mainly emitted from motorcycle. In addition, the BTEX concentration ratio was approximately 1.4: 4.0: 1.0: 4.0 .Result from the sampling of suspended particles in rainy and sunny day indicated that most of fine particles（<10um） in traffic tunnels were released from vehicles while coarse particles were contributed from the resuspension of road dust. The value of PM10/TSP in all traffic tunnels ranging from 0.27 to 0.54 indicated that most of TSP in tunnels were coarse particles. It was also revealed that motorcycles and heavy-duty diesel vehicles were major source of suspended particles.Major heavy metals detected in suspended particles were Ca, Al, and Mg, the results indicated that the major source of TSP was road dust. However, higher flowrate of vehicles would still affect the concentration of TSP. Besides, higher concentration of Zn inside the tunnel crossing Harbor than other tunnels indicated that Zn had significant correlation with heavy-duty diesel vehicles.The air pollution prevention strategies of traffic tunnels mainly included of emission sources, pollution control, reduction of exposure risk, and emergency rescue. Reduction of emission sources included the enhancement of control and penalty for violation of emission standard, the rearrangment of traffic sign and signals, the increase of clean frequency in tunnels, the construction subway or public transportation system ,such as, bus. Pollution control measured indicated air quality monitoring , ventilation system and air pollution control equipment. Reduction of exposure mainly depended up on traffic flow control and driver protection. In addition, the installation of detection, monitering and alarm system were suggested, and prevented traffic accident or the deterioration of air quality inside traffic tunnels.

One of the basic assumptions of Taguchi''s parameter design is that the error variances are not equal for all treatment conditions. Thus, the optimal level combination of parameter is determined by maximizing signal-to-noise ratio for the-smaller-the-better and the-large-the-better (LTB) type quality characteristics. On the contrary, one of the basic assumptions of experimental design is that error variance are equal for all treatment conditions. Thus, the factor level combinations whose quality characteristics is significant different from the other factors is found by using ANOVA. If the assumption of the later is true, then there is an alpha risk that Taguchi method may fail to select the optimal level combinations. The purpose of this paper is to investigate the alpha risk of Taguchi method for LTB type problem using simulation.

Demand of the remanufacturing toner cartridge has become stronger, because of the increase of the environmental consciousness. The key production and materials of toner cartridge are still held by the original company. However, the company of remanufacturing toner cartridge used trial-and-error to determine the combination of the components in the toner cartridge. It may take a lot of time and cost to find out the optimal setting using this way. In this research, we would use the Taguchi method combining with grey relation analysis and utility concept analysis to analyze the multiple quality response that includes how many papers the cartridge can print and how about the image density of the toner cartridge. This research would find out the most approximate combination of the components in the toner cartridge and discuss the impact on quality of different components. This research takes four factors that include organic photoconductor (OPC) drum, magnetic roller (MR), charge power roller (CPR), and toner for distribution of the experiment. Each factor has three treatments. So, we chose the Taguchi L9 orthogonal table for experiment. Analysis of the experiment presents the impact of OPC on quality isn’t significant. In general, the companies that product the remanufacturing toner cartridge use the new OPC to assemble the cartridge. So, the OPC would be changed or not may be the key point to reduce the material cost.

ABSTRACT Process capability analysis has been widely used and applied in industrial production processes. The objective of a process capability analysis is to estimate, monitor, and furthermore may reduce variability in industrial production processes. Additionally, process capability analysis provides a common standard of product quality for suppliers and customers. The most popular way to assess process capability is to use histograms and process capability indices (PCIs). In practice, there are many non-normal processes existed in industrial production processes, especially in the precision industrial processes, so that the use of PCIs based on the normality assumption can be misleading in many cases. In this research, we propose a new model to evaluate the non-normal process capability with smaller-the-better quality characteristic in order to achieve three goals: (1) to reflect the process status more realistically and to identify the quality characteristics of the non-normal process correctly, (2) to define, interpret and use PCIs adequately, and (3) to evaluate the non-normal process capability properly. This new model includes three functional modules. The data collection and clustering module collects and analyzes the data of process quality characteristics to find its own data types, and then separate the data appropriately into some data segments. The distribution-fitted module treats each data segment by goodness of fit method to find their approximation distribution function, and then calculates the process control limits, percentiles and the upper bound of defective rate. Finally, the PCIs evaluating module defines and calculates individual PCI and aggregate PCI of the process ( particularly for Cpu and “Equivalent”Cpu ) based on yield information. After experimenting with some examples for processes of smaller-the-better quality characteristic, It shows that this approach could avoid besetments and mistakes which may be exists when using traditional methods. Keywords: Process Capability Analysis, Non-normal processes, Smaller-the-Better Quality, Approximation Distribution Function, “Equivalent”Cpu

In recent years, the adaptation of Customer Relationship Management (CRM) has been recognized as an important tool to improve customer satisfaction by most enterprises. Customer satisfaction is one of the most representative indexes which can be influenced by the product or service performance. Most enterprises will perform customer satisfaction surveys and measure the product or the service performance and overall satisfaction. However, it is important to know the critical drivers of product or service performance which have great impact on the overall customer satisfaction. Kano model is the most well-known methodology to study the impact based on the categorized of the product or service attributes. On the basis of Kano model, there are several different categorized methods have been proposed. However, for a same data set, these methods could derive different outcomes due to their different arguments and assumptions. From the practical usage of point, an attribute with different impact categorized could baffle an analyzer. The main purpose of this research is to study characteristics of three categorized methods: Dual Importance Mapping (DIM), Penalty Reward Contrast Analysis (PRCA) and Correspondence Analysis (CA). The real case data sets were analyzed by using three methods, the different outcomes was compared and correct outcome was suggested. Besides, the outcome of this study will set up rules for the practical users as a selection guideline for choosing a proper Kano attribute categorized method.

In Taguchi’s parameter design, the optimal parameter levels are found by maximizing the signal-to-noise ratio of the quality characteristic. In this research, it is assumed that (1) the quality characteristic is normally distributed (2) the mean and standard deviations of all treatment combinations are equal. Thus, the alpha risk is that some factors are misidentified as significant factors. The purpose of this research is to investigate the alpha risk of Taguchi method for L12 by simulation. The results show that the alpha risk is very high for this orthogonal array.

One of the basic assumptions of Taguchi’s parameter design is that the error variances are not equal for all treatment conditions. Thus, the optimal level combination of parameter is determined by maximizing signal-to-noise ratio for the quality characteristics. On the contrary, one of the basic assumptions of experimental design is that error variance are equal for all treatment conditions. Thus, the factor level combinations whose quality characteristics is significant different from the other factors is found by using ANOVA. If the assumption of the later is true, then there is an alpha risk that Taguchi method may fail to select the optimal level combinations. The purpose of this paper is to investigate the alpha risk of Taguchi method for the-larger-the-better (LTB) type problem using L18 by simulation.

The monitoring wells on shallow layer in the area of Kaohsiung County were established by EPA (Environmental Protection Administration) under the project of “The integrated programming on groundwater quality of the monitoring network in Taiwan area” to periodically execute the sampling and monitoring of groundwater quality. The sampling of water quality data provided through the years can be utilized to judge the information of groundwater pollution at that time. In order to simplify the numerous monitoring items of groundwater quality and to search for the factors representing the pollution types as well as sources of groundwater quality in the Kaohsiung County, this study utilizes the multivariate statistical method to analyze the characteristics of the groundwater quality. Four principal factors were summarized as: (1) salted factor including electrical conductivity (EC), hardness, chloride (Cl-), sulfate (SO4=), sodium (Na), potassium (K), magnesium (Mg); (2) mineral factor including iron (Fe), manganese (Mn); (3) zinc environmental factor including Zinc (Zn); and (4) organic pollutant factor including total organic carbon (TOC). The four major principal factors on the groundwater quality in the area of Kaohsiung County can interpret the 79.5% variances of the integrated groundwater characteristics. Four groups were classified according to the similar characteristics and the variety of water quality among groups using the cluster analysis method. The results showed that the groundwater quality of hinterland was better than that of coastal area. Some coastal areas have already been affected by the seawater intrusion results in salting situation. The regional groundwater quality was classified from the hardness water to very hardness water. The general index of groundwater pollution determined by multivariate statistical method was compared their similarities with those determined by the method of Stiff shape diagram and the method of Piper diagram. The statistical method provided by this research can reduce the harassment of the missing items of monitoring water quality. The results of this research may provide the authority about the strategy preparation and execution suggestion for the groundwater monitoring and pollution prevention.

The purpose of this study was to explore the relationship among disease characteristic, self-care behavior and quality of life for Hemodialysis patients. Questionnaire survey between gender had been conducted on the Hemodialysis patients with age over 18 in North Taiwan area. Responses of 266 patients selected by Quota Proportional Sampling were statistically analysed with descriptive statistics, correlation analysis, canonical correlation analysis and structural equation modeling. The results of study are following：Most of the subjects are married, unemployed , with age 45 or above and have 7 year hemodialysis history averagely. Among all of them, 33% s has high overall quality of life, 22% has somewhat low overall quality of life , especially for Physical and Psychological Domain. Those with better self-care behavior have slighter disease characteristic. And the symptom control liability from medicine outweighted the influence from diet. The SEM shows that there are significant relationship between Disease characteristics and quality of life and also between the Disease characteristics and self-care behaviors.
