Abstract:
Competitive global markets are increasing the commercial pressure on manufacturing companies to develop better products in less time. To meet these demands, the appliance manufacturer, Fisher & Paykel, has considered the use of computer simulation of fluid flows to assist in product design. This technology, known as Computational Fluid Dynamics (CFD), has the potential to provide rewarding insight into the behaviour of designs involving fluids. However, the investment in CFD is not without risk. This thesis investigates the use of CFD in oven design expressly to evaluate the numerical accuracy and suitability of CFD in the context of oven product development. CFD was applied to four cases related to oven design, along with detailed experimental investigations, and resulted in a number of relevant findings. In a study of an impinging jet, the SST turbulence model was found to produce better results than the k-ε turbulence model. Measurements indicated that the flow was unsteady, but CFD struggled to reproduce this behaviour. The synergy between experimental and numerical techniques was highlighted in the simulation of a two-pane oven door, and resulted in temperatures on outer surface of the door predicted by CFD to within 2% of measured values. In the third study, a CFD simulation of a tangential fan failed to deliver acceptable steady-state results, however a transient simulation showed promise. The final case examined the flows through the door and cooling circuit of the Titan oven. Velocities predicted by CFD compared well against measurements in some regions, such as the potential core of the jet at the outlet vent, but other regions, such as entrained air, were poor. Temperatures were predicted to within an average of 2% of measured values. It is found that limited accuracy does not necessarily prevent CFD from delivering engineering value to the product development process. The engineering value delivered by CFD is instead more likely to be limited by the abilities of the user. Incompatibilities between CFD and the product development process can reduce the potential value of CFD but the effects can be minimised by appropriate management action. The benefits of CFD are therefore found to be sufficient to merit its use in the product development process, provided its integration into the organisation is managed effectively and the tool is used with discernment. Recommendations for achieving this are provided.

Abstract:
The purpose of this study was to develop a framework for analysis and assessment of the cost of ownership and use of major cooking appliances. This involved an assessment of the monetary cost as well as the cost of human resources required to maintain and operate cooking systems. The goal was to provide information useful in making purchase decisions within a framework that can be used to organize information about cost beyond the initial purchase price. Five cooktops--conventional electric coil, induction, solid element with thermostatic control, solid element with thermal limiter, and gas--and a microwave oven were used to develop a decision-making matrix. Data were collected in the Virginia Polytechnic Institute and State University College of Human Resources household equipment laboratory. In addition, data were compiled from previous studies which included the same variables. One-way analysis of variance, Student-Newman-Keuls, and Tukey’s HDS techniques were used to analyze the data. Results were used to assign weights in the matrix used to develop a 10-point scale which represented the total cost of owning and using a cooking system in food preparation. The scale was then used to evaluate the appliances used in this study. Based on the matrix, the microwave oven received the highest score followed by gas, conventional electric coil, solid element with thermostatic control, solid element with thermal limiter, and induction cooktops. The cost of owning and using any of these appliances is not markedly different in terms of life expectancy, maintenance, energy, or cooking time. However, such factors as user interaction with the appliance, speed of heat-up, heat recover rate, retained heat, evenness of heating, cleaning time, and initial purchase price do vary and are likely to influence satisfaction with a cooking system.

Abstract:
Includes bibliographical references (p. 229-239).
Multi-view shape-from-silhouette systems are increasingly used for analysing stones. This thesis presents methods to estimate stone shape and to recognise individual stones from their silhouettes. Calibration of two image capture setups is investigated. First, a setup consisting of two mirrors and a camera is introduced. Pose and camera internal parameters are inferred from silhouettes alone. Second. the configuration and calibration of a high throughput multi-camera setup is covered. Multiple silhouette sets of a stone are merged into a single set by inferring relative poses between sets. This is achieved by adjusting pose parameters to maximise geometrical consistency specified by the epipolar tangency constraint. Shape properties (such as volume, flatness, and eiongation) are inferred more accurately from the merged silhouette sets than from the original silhouette sets. Merging is used to recognise individual stones from pairs of silhouette sets captured on different occasions. Merged sets with sufficient geometrical consistency are classified as matches (produced by the same stone), whereas inconsistent sets are classified as mismatches. Batch matching is determining the one-to-one correspondence between two unordered batches of silhouette sets of the same batch of stones. A probabilistic framework is used to combine recognition by merging (which is slow, but accurate) with the efficiency of computing shape distribution-based dissimilarity values. Two unordered batches of 1200 six-view silhouette sets of uncut gemstones are correctly matched in approximately 68 seconds (using a 3.2 GHz Pentium 4 machine]. An experiment that compares silhouette-based shape estimates with mechanical sieving demonstrates an application using the developed methods. A batch of 494 garnets is sieved 15 times. After each sieving, silhouette sets are captured for sub-batches in each bin. Batch matching is used to determine the IS sieve bins per stone. Better estimates of repeatability, and better understanding of the variability of the sieving process is obtained than if only histograms (the natural output of sieving) were considered. Silhouette-based sieve emulation is found to be more repeatable than mechanical sieving.

Abstract:
A high-order finite difference solver was written to solve the incompressible Navier-Stokes (NS) equations and was applied to analyze the blood flow. First, a computer code was written to solve incompressible Navier- Stokes equations using the exact projection method/fractional step scheme. A fifth-order weighted essentially nonoscillatory (WENO) spatial operator was applied to the convective terms of Navier-Stokes equations. The diffusion term was solved by using a sixth-order compact central difference scheme. A fractional step scheme in conjunction with the third-order Runge-Kutta total variation diminishing (RK TVD) scheme was used for the time discretization. At this stage, non-Newtonian effects and the pulsatile nature of the flow were not included. The developed Newtonian flow code was tested using benchmark problems for incompressible flow, namely, the driven cavity flow, Couette flow, Taylor-Green vortex problem, double shear layer problem, and skewed cavity flow. The results were compared with existing published experimental data in order to build confidence that the computer code was working properly in the simple blood flow conditions, i.e., as a Newtonian fluid. In the second stage, the backward-facing step was analyzed for Newtonian steady and pulsatile flow, and for non-Newtonian steady and pulsatile flow. The results were compared with experimental data and found to be in agreement. In the third stage, the computer program was extended to three dimensions. Flow through an infinite long pipe and through a 90-degree bend was carried out. The velocity profile in the pipe and at different locations of the bend was obtained, and the numerical values indicate good agreement with analytical and experimental values.

Many people in the developing areas of the world struggle to cook with stoves that emit hazardous fumes and contribute to green house gas emissions. Electric stoves would alleviate many of these issues, but significant barriers to adoption, most notably lack of reliable electric power, make current commercial options infeasible. However, a stove with an input power of 24V DC elegantly solves the issue of intermittent power by allowing car batteries to be used instead of a grid connection, while also allowing seamless integration with small scale solar installations and solar-based micro-grids. However, no existing commercial stoves nor academic research have attempted to create an induction stove powered from a low voltage DC source. This paper presents the design of a low voltage current-fed, full-bridge parallel resonant converter stove. The dynamics of this new topology are discussed in detail and simulations are provided to analyze the behavior. Additionally, a practical implementation of a 500W - 1 kW stove is described. This stove is the first of it's kind and represents a new contribution to both the field of induction cooking and the field of clean cooking solutions for the developing world.

Abstract:
This research performed Reynolds-averaged Navier-Stokes (RANS) simulations for the flow past an aircraft protrusion mounted on a flat surface. The major factor in this research is the investigation of shock-wave/boundary-layer interactions (SWBLIs). RANS computations were performed using the Spalart-Allmaras turbulence model and a second-order Navier-Stokes solver. The two complex three-dimensional geometries primarily focused on in this research were the circular-arc bump antenna and the TT-5006A antenna. Numerical results were in good agreement with the wind tunnel experimental results; however, some discrepancies in the flow properties occurred at the shock-interaction region. Computations were performed using the commercial software computation fluid dynamics (CFD) tool FLUENT in the High Performance Computing Center (HiPeCC) at Wichita State University.

Full text
Abstract:
A remote procedure call (RPC) mechanism permits the calling of procedures in another address space. RPC is a simple but highly effective mechanism for interprocess communication and enjoys nowadays a great popularity as a tool for building distributed applications. This popularity is partly a result of their overall simplicity but also partly a consequence of more than 20 years of research in transpaxent distribution that have failed to deliver systems that meet the expectations of real-world application programmers. During the same 20 years, persistent systems have proved their suitability for building complex database applications by seamlessly integrating features traditionally found in database management systems into the programming language itself. Some research. effort has been invested on distributed persistent systems, but the outcomes commonly suffer from the same problems found with transparent distribution. In this thesis I claim that a higher-order persistent RPC is useful for building distributed persistent applications. The proposed mechanism is: realistic in the sense that it uses current technology and tolerates partial failures; understandable by application programmers; and general to support the development of many classes of distributed persistent applications. In order to demonstrate the validity of these claims, I propose and have implemented three models for distributed higher-order computation over autonomous persistent stores. Each model has successively exposed new problems which have then been overcome by the next model. Together, the three models provide a general yet simple higher-order persistent RPC that is able to operate in realistic environments with partial failures. The real strength of this thesis is the demonstration of realism and simplicity. A higherorder persistent RPC was not only implemented but also used by programmers without experience of programming distributed applications. Furthermore, a distributed persistent application has been built using these models which would not have been feasible with a traditional (non-persistent) programming language.

Abstract:
The application of electronic-resonance enhanced (ERE) coherent anti-Stokes Raman scattering (CARS) for the detection of nitric oxide (NO) and acetylene (C2H2) is experimentally demonstrated and the effects of various parameters on the ERE CARS signal investigated. In addition, the detection of dipicolinic acid (DPA) using “normal” CARS is demonstrated. For NO detection, the frequency difference between a visible Raman pump beam and Stokes beam is tuned to a vibrational Q-branch Raman resonance of the No molecule to create a Raman polarization in the medium. The second pump beam is tuned into resonance with the rotational transitions in the (1,0) band of the A2Σ+-X2Π electronic transition at 236 nm, and the CARS signal is thus resonant with transitions in the (0,0) band. A NO gas cell was used for the experiment to detect NO at various pressure levels. A significant resonant enhancement of the NO CARS signal was observed and good agreement between calculated and experimental data was obtained. For C2H2 detection, ERE CARS experiments were performed in a roomtemperature gas cell using mixtures of 5000 ppm C2H2 in N2. Visible pump and Stokes beams were used, with the frequency difference between the pump and Stokes tuned to the 1974 cm-1 Ϡ2 Raman transition of C2H2. An ultraviolet probe beam with the wavelengths ranging from 232 nm to 242 nm is scattered from the induced Raman polarization to generate the ERE CARS signal. The effects of probe wavelength and pressure on signal generation are discussed. CARS was used to detect the 998 cm-1 vibrational Raman transition from a sample of polycrystalline DPA. The transition is the breathing ring vibration in the pyridine ring structure in the DPA molecule. The DPA 998 cm-1 transition is detected with excellent signal-to-noise ratio and the full-width-at-half-maximum is very narrow, approximately 4 cm-1.

In recent years, the South African online shopping industry has experienced remarkable growth which has attracted multi-national online stores to operate in the South African market thus creating competitive pressure for domestic online stores. Consequently, this presence of competition from well-resourced and recognisable online store brands it is critical that domestic online stores adopt measures to protect their competitive positions and to pursue competitive advantage. An adoption of a customer-centred approach focused on increasing customer satisfaction is one strategy for online stores to consider. This study had as its primary objective to develop a theoretical model of psychographic influences on customer satisfaction with electronic service quality. The associated objectives were to develop a theoretical model to (i) assess online shopping customers’ perceptions of electronic service quality, (ii) illustrate the effect of electronic service quality on customer satisfaction, (iii) measure the effect of customer satisfaction on customer behavioural intentions, and (iv) determine how customers’ perceptions of electronic service quality differ across different customer psychographic profiles. A quantitative descriptive cross sectional study was conducted to address the research objectives. Data was collected through a questionnaire from a sample of 344 South African online store customers. Statistical descriptive and inferential analyses were performed including mean values, structural equation modelling and analysis of variance. The findings included that, i) customers have negative perceptions of electronic service quality in South African online stores, ii) the constructs of electronic service quality, efficiency and contact, have a significant positive effect on customer satisfaction, iii) customer satisfaction has a significant positive effect on customer behavioural intentions, and iv) a significant difference in the perceptions of electronic service quality was found to exist among customers with different psychological profiles. Based on the study findings it is recommended that South African online stores should improve electronic service quality and apply market segmentation on the basis of customer psychological profiles in order to gain competitive advantage.

Abstract:
2002/2003
La struttura elettronica ed il magnetismo di atomi singoli e impurezze di metalli di transizione deposti su superfici metalliche sono stati studiati per mezzo di tecniche dicroiche di assorbimento dei raggi X (XMCD) e misure di magnetizzazione, in alti campi magnetici ed a temperature criogeniche. Le caratteristiche uniche delle XMCD nell'investigare sia momenti magnetici di spin che orbitali con selettività chimica sono state applicate a sistemi estremamente diluiti, con concentrazione di superficie dell'ordine di 1012 atomi cm-2 , fino al limite di atomi isolati. Questo genere di misure è stato applicato ai sistemi di impurezze di superficie soltanto in ultimi anni grazie alla disponibilità di sorgenti di radiazione di sincrotrone di elevata brillanza. Ad oggi queste misure rappresentano un esempio di punta nello studio sul magnetismo delle impurezze di superficie. l risultati sono riportati per tre gruppi di sistemi: Impurezze di V e Mn sulla superficie dei metalli alcalini (Cs, K, Na); atomi isolati di Mn, V, Fe, Co sulla superficie Cu(100) ed atomi isolati di Co su Pt(111 ).Inoltre è presentato uno studio della distribuzione dei momenti magnetici di uno strato monoatomico di manganese accoppiato alla superficie Fe(1 00). Il manganese su potassio è stato indicato possedere una configurazione elettronica simile a quella atomica d5 . Questa configurazione elettronica è particolarmente stabile per i piccoli cambiamenti di ibridazione indotti dal cambiamento della densità elettronica nei dai metalli alcalini. Se l'ibridazione è ulteriormente aumentata come nel caso di atomi di M n deposti su Al(1 00) le caratteristiche spettroscopiche che si evidenziano in strutture di multipletti atomici negli spettri sono soppresse e con esse il magnetismo. Le impurezze di vanadio sulle superfici alcaline mostrano una configurazione elettronica che non più così simile a quella degli atomi liberi, come ad esempio le configurazioni d o d4 .11 momento orbitale è trovato essere piccolo, minore di 0.5 f.ls, rispetto al momento orbitale delle configurazioni puramente atomiche, ma in similitudine con esse è allineato antiparallelamente al momento di spin. Inoltre il momento orbita le diminuisce risalendo lungo la colonna dei metalli alcalini (gruppo 1 A della tabella periodica degli elementi), cioè andando dal Cs al Li, mentre la densità elettronica è aumentata. Questo effetto è legato all'aumento dell'ibridazione dovuta alla maggiore densità elettronica. l momenti magnetici misurati sono dell'ordine di 3 f.ls e non possono essere spiegati con parametri puramente atomici. Due meccanismi possibili vengono proposti per spiegare l'estinzione parziale del momento orbitale: l'effetto di un debole campo cristallino e l'effetto dell'ibridazione in concomitanza con maggiore larghezza dello stato regato di Friedel nel caso dei primi elementi della serie dei metallo di transizione 3d. Gli atomi isolati di Fe sulla superficie del Cu(1 00) mostrano una grande anisotropia magnetica, di 1,5 me V/atomo ed un momento magnetico orbitale aumentato rispetto al Fedi volume. Il substrato di Cu non contribuisce considerevolmente all'anisotropia come nel caso del Co su platino. All'opposto gli atomi isolati di Co su Cu(100) non mostrano alcuni dicroismo e quindi alcun magnetismo. Questo risultato è spiegato in termini di effetto Kondo, poiché i singoli atomi di Co sono stati trovati per essere un sistema di Kondo con T K=88 K. Un confronto dei dati sperimentali per impurezze di V, M n, Fe e Co su Cu(1 00) con il comportamento magnetico calcolato dei adatomi lungo la serie 3d, mostra un buon accordo generale, ma con deviazioni importanti per le impurezze di Co e di V. Atomi singoli atomi di Co sulla superficie del Pt(111) hanno una straordinaria anisotropia magnetica di circa 9,2 meV/atomo (circa 1000 volte quella del Co di volume) ed ad oggi la più alta energia di anisotropia magnetica misurata per un sistema magnetico. L'origine di un effetto cosi' grande risiede in un momento orbitale aumentato dalla ridotta coordinazione del singolo atomo, alla rottura di simmetria sulla superficie ed all'effetto dell'ibridazione del platino, conseguenza di un mescolamento di stati 3d-5d tra Co ePt, che porta il substrato a contribuire all'anisotropia magnetica totale.
The electronic structure and the magnetism of transition metal single atoms and magnetic impurities on metal surfaces have been studied by means of x-ray absorption dichroic techniques (XMCD, and magnetization measurements) in high magnetic fields and at low temperatures. The unique capabilities of XMCD to probe the both spin and orbital magnetic moments with element selectivity have been applied to diluted systems with low surface concentration (1012 atoms cm-2 ) down to the limit of isolated atoms. This kind of measurements have been applied to surface impurity systems only in the last few year thanks to the availability of high flux and brilliance synchrotron radiation sources. At the present these measurements represent the state of the art in the study of the magnetism of surface impurities. Results are reported for three different classes of systems: Mn and V impurities on the surface of alkali metals (Cs, K, N a); M n, V, Fe, Co single atoms on the Cu(1 00) surface an d Co single atoms on the Pt(111) surface. Furthermore results have been presented, regarding the magnetic moment distribution of a Mn monolayer coupled to the Fe(1 00) surface. Manganese on potassium has been shown to possess an atomic like magnetic d5 electronic configuration. This electronic configuration is particularly stable for small hybridization changes induced by alkali metals of increased electronic density. lf the hybridization is further increased as on Al(100) the spectroscopic features related to atomic multiplets are suppressed together with magnetism. Vanadium impurities on alkali metal surfaces also show atomic multiplet features. The electronic configuration is not an atomic-like configuration as d3 or d4 . The orbital moment is found to be small, less than 0.5 !-ls with respect to the purely atomic configurations and to be antiparallel to the spin. lt decreases along the alkali metals column (group 1A) of the periodic table, as the electronic density is increased, i.e. going from Cs to Li. This effect is related to an increased hybridization with the substrate due to the larger electronic density. The measured magnetic moments are of the order of 3)-ls, and cannot be explained with simple atomic parameters. Two possible mechanisms have been proposed to explain the partial quenching of the orbital moment, the effect of a weak crystal field and the effect of hybridization through the larger width of Friedel resonant bound state for the early elements of 3d transition metal series. Fe single atoms on Cu(100) surface have a large ot1f of plane magnetic anisotropy of 1.5 meV/atom and enhanced orbital magnetic moment with the respect to the bulk. The Cu substrate does not contribute considerably to the anisotropy as in the case of Co o n Pt. At the apposite Co single atoms on Cu(1 00) surface do not show any dichroism an d hence magnetism. This result ca n be explained on the basis of the Kondo effect, since Co single atoms have been found to be a Kondo system with T K=88 K. A comparison of the experimental data for V, Mn, Fe, Co impurities on Cu(100) with the calculated magnetic behavior of adatoms along the 3d series, gives an overall reasonable agreement, with important deviations for V and Co impurities. Co single atoms on the Pt(111) surface have an extraordinary large out of plane magnetic anisotropy of about 9.2 meV/atom due to the interplay between an enhanced orbital moment, consequence reduced coordination of the single atom, at the surface, and the effect of Pt hybridization, consequence of a d-d mixing between Co and Pt orbitals. This result is of particular relevance since this magnetic anisotropy is the highest measured, by now, for any system.

Lo scopo della presente tesi è l'applicazione e lo sviluppo del metodo LCAO B-spline DFT, basato sulla Combinazione Lineare degli Orbitali Atomici (LCAO), sulla Teoria del Funzionale Densità (DFT) e sull'impiego delle funzioni di base Bspline, per lo studio della fotoionizzazione molecolare. Nel Capitolo 1 viene considerata una breve introduzione al processo di fotoionizzazione e alla teoria della fotoionizzazione molecolare. Nel Capitolo 2 vengono presentati i metodi computazionali utilizzati durante il presente lavoro di tesi. I risultati ottenuti sono presentati nei successivi Capitoli della tesi. Il lavoro è suddiviso in tre parti. Nella prima parte (Capitoli 3-6) il metodo LCAO B-spline DFT è applicato allo studio del Dicroismo Circolare nella Distribuzione Angolare (CDAD) dei fotoelettroni emessi da molecole chirali, ionizzate da luce circolarmente polarizzata di definita elicità. Un primo studio computazionale sull'effetto CDAD è focalizzato su una serie di derivati chirali dell'ossirano, con lo scopo di identificare tendenze lungo la serie molecolare. I risultati evidenziano una inaspettata sensibilità da parte del dicroismo circolare verso cambiamenti nella struttura elettronica molecolare. Inoltre i valori calcolati sottolineano come lintensità dell'effetto CD AD è da attribuire non tanto alla chiralità dello stato iniziale, ma bensì alla capacità della funzione d'onda del fotoelettrone (completamente delocalizzata su tutta la molecola) di sondare l'asimmetria nel potenziale molecolare effettivo. Il metodo LCAO B-spline DFT è quindi applicato allo studio del dicroismo circolare nella distribuzione angolare dei fotoelettroni emessi dai livelli di core e di valenza degli enantiomeri della canfora. I risultati sono confrontati con i valori calcolati attraverso l'approccio Continuum Multiple Scattering: i due metodi teorici mostrano un sostanziale accordo nei risultati. Inoltre, un confronto dei risultati calcolati con i dati sperimentali disponibili mostra un accordo sostanziale se non addirittura quantitativo. E' inoltre presentato uno studio teorico e sperimentale sul dicroismo circolare nella distribuzione angolare dei fotoelettroni emessi dai livelli di valenza del 3- idrossitetraidrofurano, il quale è una molecola relativamente flessibile. Questo lavoro mette luce su nuove caratteristiche del dicroismo in fotoemissione, il quale appare molto sensibile a fattori di tipo conformazionale. L'influenza degli effetti conformazionali sui parametri dinamici di fotoionizzazione, con particolare attenzione all'effetto CDAD, è quindi investigata in dettaglio. Il metodo LCAO E-spline DFf è applicato ai conformeri della molecola (1R,2R)-1,2-dibromo-1,2-dicloro-1,2-difluoroetano. Il parametro dicroico mostra una significativa sensibilità verso il conformero della molecola. Ciò suggerisce che il profilo energetico del parametro dicroico potrebbe essere utilizzato come un fingerprint dei conformeri di una molecola chirale. Il metodo computazionale è anche applicato alla rotazione del metile nella molecola (S)-ossirano, in modo da verificare l'assunzione che la rotazione del metile non influisca in maniera significativa sui valori calcolati dell'effetto CDAD. Si verifica invece come la rotazione del gruppo metile provochi variazioni inaspettate e drammatiche sul profilo del parametro dicroico. La seconda parte del lavoro (Capitolo 7) riguarda l'investigazione teorica sulla correttezza dell'assunzione che il Eranching Ratio nella ionizzazione dei livelli di core di siti atomici chimicamente diversi dello stesso elemento, segua il rapporto statistico. Il metodo LCAO E-spline DFT è stato impiegato per calcolare in maniera accurata le sezioni d'urto associate alla ionizzazione degli orbitali ls dei carboni per un set di molecole organiche scelte. I risultati mostrano che deviazioni nella sezione d'urto inducono forti andamenti non statistici da parte dei Eranching Ratios relativi alla ionizzazione dei livelli core, fino a diversi e V sopra la soglia di ionizzazione. La parte finale della tesi (Capitolo 8) riguarda il problema delle shape resonances. La razionalizzazione delle strutture risonanti, spesso presenti nello spettro molecolare del continuo, è un problema ampiamente discusso. Nel presente lavoro una nuova metodologia per localizzare e caratterizzare in termini molecolari le shape resonances viene proposta. Partendo da un sistema modello, è stato sviluppato un metodo per caratterizzare le risonanze in termini di contributo da parte degli orbitali virtuali di valenza. Il metodo sviluppato è quindi esteso al caso molecolare ed applicato alla localizzazione e caratterizzazione delle shape resonances che appaiono nella fotoionizzazione dei livelli crg di core e di valenza di N1.

Abstract:
Following changes to the Federal Rules of Civil Procedure in 2006 dealing with the role of Electronically Stored Information, digital forensics is becoming necessary to the discovery process in civil litigation. The development of case law interpreting the rule changes since their enactment defines how digital forensics can be applied to the discovery process, the scope of discovery, and the duties imposed on parties. Herein, pertinent cases are examined to determine what trends exist and how they effect the field. These observations buttress case studies involving discovery failures in large corporate contexts along with insights on the technical reasons those discovery failures occurred and continue to occur. The state of the art in the legal industry for handling Electronically Stored Information is slow, inefficient, and extremely expensive. These failings exacerbate discovery failures by making the discovery process more burdensome than necessary. In addressing this problem, weaknesses of existing approaches are identified, and new tools are presented which cure these defects. By drawing on open source libraries, components, and other support the presented tools exceed the performance of existing solutions by between one and two orders of magnitude. The transparent standards embodied in the open source movement allow for clearer defensibility of discovery practice sufficiency whereas existing approaches entail difficult to verify closed source solutions. Legacy industry practices in numbering documents based on Bates numbers inhibit efficient parallel and distributed processing of electronic data into paginated forms. The failures inherent in legacy numbering systems is identified, and a new system is provided which eliminates these inhibiters while simultaneously better modeling the nature of electronic data which does not lend itself to pagination; such non-paginated data includes databases and other file types which are machine readable, but not human readable in format. In toto, this dissertation provides a broad treatment of digital forensics applied to electronic discovery, an analysis of current failures in the industry, and a suite of tools which address the weaknesses, problems, and failures identified.

Abstract:
In manufacturing processes, the quality of a product often depends on its surface, and careful control of surface properties is critical to meet customer requirements. A thin layer of polyethylene (PE) is applied to paperboard to increase barrier functionality and high optical quality of the product. For PE-coated paperboard, product quality inspection is performed at the end of the manufacturing process by taking a portion of the reel to the laboratory for quality inspection. These associated offline characterization methods are destructive and time consuming and are representative of only a small portion of the product. The overall goal of this thesis is to provide new methods to characterize the Surface properties of PE-coated paperboard. Specifically, to determine imaging techniques for measuring surface parameters that affect its barrier functionality and surface roughness. In this thesis, two methods for surface characterization of PE-coated paperboard are presented to quantify the two most important product-related quality parameters, i.e. barrier functionality and optical quality, which are affected by the presence of defects in the coating and by the surface roughness of the product, respectively. First, a full-Stokes imaging polarimeter (FSIP) is used to detect the presence of PE-coated material and to distinguish between coated and uncoated samples at the pixel level. Second, a three-dimensional scanning electron microscope (3D SEM) is employed to calculate the Surface roughness of PE-coated paperboard. These surface characterization techniques offer an advantage over the industry standard due to the high speed and non-contact nature of the measurement, while increasing the throughput of the sample surface parameters studied. A classification accuracy of 99, 74% is achieved using a FSIP to distinguish between PE- and non-PE-coated paperboard at pixel level. Using the 3D SEM technique to measure the topography of PE-coated samples results in a faster method that is comparable in accuracy to a chromatic confocal microscope (CCM). The surface roughness measured with the 3D SEM differs from the standard method by up to 6% and good agreement with statistical parameters is found. In general, surface analysis of PE-coated is often a complex and difficult task for imaging techniques and suitable methods need to be evaluated for their sensitivity to measure the desired surface parameters. The presented characterization techniques inspect larger areas of PE-coated paperboard compared to current industry standards. These methods provide a quantitative solution for surface characterization to inspect the surface parameters necessary to assure the product’s quality.

Entering Web 2.0, online shoppers are more used to search product information before purchasing and share their comments after shopping. The MIC survey indicates that over 70% of online shoppers will explore the comments of others before purchasing and be affected. This shows that electronic Word-of-Mouth (eWOM) has a great influence on customers’ purchasing decision and worthy watching. Cosmetic in online stores could not be trail before purchasing, which is contrary to its experice quality product characters and lead to the booming of cosmetic community sites. In addition, many of the online cosmetic websites include the function called “True Story” to encourage customers share their experiences after using products, which means online cosmetic stores already know the power of eWOM and start to apply it in business operation. Even the influence and application of eWOM are already been proven, there are only still little researches relate to eWOM management. This study built a systematic structure to find the motivation and process for eWOM management of online cosmetic stores, tried to identify the context of this vague but important issue. The study aims to investigate the following questions: 1. What are the motivations for online cosmetics stores to manage eWOM? 2. How do they monitor eWOM? 3. How do they respond to eWOM? 4. How do they disseminate eWOM? Through interviewed three online cosmetic stores in Taiwan and applied secondary data analysis, the preliminary research findings include: 1. The motivations to manage eWOM for online cosmetic stores are collecting market information and building brand trust. 2. Online cosmetic stores take advantage of cosmetic community sites and official websites to monitor eWOM, identify the importance of eWOM by the detail descriptions. 3. Online cosmetic stores will optionally respond to negative eWOM to pacify and show the sense of responsibility. 4. Online cosmetic stores apply customer referral program, beauty knowledge conveying and promotion activities to increase the positive eWOM. 5. The respond mechanisms in online cosmetic websites also contribute to monitor and dissemination of eWOM. The study also contributed to the eWOM management theory by: 1. Supplement to the lack of eWOM respond and dissemination mechanisms. 2. Provide new references for eWOM management model revising. 3. Found the new relationship between eWOM and traditional marketing communication tools.

With increasing of popularity and growing of Broadband Network rapidly in Taiwan, the acceptance degree of consumers to Electronic Store is rising. According to the forecast of Institute for Information Industry, E-commerce market will grow and reach 50,100 million NT dollars by a wide margin in 2005. Because the appearing of business opportunity of the market, enterprises carried on E-Marketplace one after another. They believed that E-Marketplace will attract more people to participate in the operation of the Electronic Stores with the reducing of the technological threshold of information. Electronic Stores itself has looks relatively unique characteristic to the traditional stores, and the technology of information will not be a barrier to operate Electronic Stores. Why don’t people run Electronic Stores very successful? From the viewpoints of consumers, this study wants to find out what store images of Electronic Stores could catch consumers’ eyes. Furthermore, this study regarded FCB Grid as a classified basis of goods to find out what difference between store images of Electronic stores to consumers when they deal with different kinds of goods? The purposes of this study are below: 1. What store images of Electronic Stores do customers place importance on? 2. What difference between store images of Electronic stores to customers when they deal with different kinds of goods? With convenience sampling, this study collected the data by network questionnaire and face-to-face interview with people who had consumption experience in the Electronic Stores. The effective samples add up to 458. The result of study includes: 1. The top six components of store images which consumers place importance on Electronic stores are security, service quality, after-sale service, information, products quality and operation convenience. 2. It is failed to find the significant proof to prove that consumers will place different importance level on store images when they consume different kind of goods.

After over seventy-five years of development, the home appliance industry in Taiwan is a mature market. However, sales channels are still evolving and include traditional community appliance stores chained appliance stores, hyper wholesale shops and web shops for on-line ordering. The competition of the sales channels is fierce among all kinds of selling approach. The study is based on “Push-Pull-Moor” (PPM) theory to develop a research model to investigate the factors keeping consumers continually patronize traditional community appliance stores. The findings showed that the traditional appliance stores are still preferred by locals due to its strongest mooring effect of switching costs, even under the pushing force effect of poor store image and strong competitors' attraction pulling force effect. This study concluded three recommendations for the operational reference of traditional appliance stores.

Jegadeesh and Titman (1993) document the momentum strategy. Investors tend to underreact to new information, so that the stock price has the phenomenon of momentum. With buying the prior winners and selling the prior losers, the momentum strategy has obtained abnormal return over 3–12 months. This study forms the portfolios with1, 3, 6, 9, 12 months formation and holding periods to investigate whether abnormal positive returns in Taiwan stock market in 1991-2005 can be obtained by some investment strategies. We also examine the returns of momentum strategy in business cycle and stock market cycle. Moreover, we use economic indicators and technical analysis diagrams to form the investment portfolios and then to discuss whether these indicators provide useful information on forming strategies. Our empirical results show that the average return of momentum strategy is not significant positive in Taiwan stock market during 1991-2005. However, momentum strategy with information of business cycle and stock market cycle obtain positive profit. The winner portfolio is better than momentum portfolio in the expansion of business cycle and bull market. On the other hand, The loser portfolio perform better than momentum portfolio in the recession of business cycle and bear market. The period of momentum phenomenon in stock market cycle lasts longer than that in business cycle. The momentum portfolio in stock market cycle performs better than that in business cycle. In addition, leading indicator and the technical analysis of Moving Average(MA) provide useful information to investors.

We use the weekly return data from the first week in 1995 to the 8th in 1999 to discuss if the behavior of electronic stocks is according to the overreaction hypothesis. We use the weekly data instead of daily data as former review, because the variance of daily data is larger and there are some limits in Taiwan’s stock market; therefore, the weekly data can really react the short-run trend. Besides, we classify the electronic stocks according to the size, there are large, median, and small, to test if the stock behavior is according to the overreaction hypothesis. Here, we mainly discuss the strategies, the first one is to buy the loser and sell the winner at the same time (contrary strategy), which is the two-way strategy, and the other one is buy the winner or sell the loser at this time, which is a one-way strategy. We now discuss separately these two strategies if there is abnormal return in the situation. Without considering size effect, the results show that the first strategy (contrary strategy) will get the negative excess return; the second one shows it is obvious the excess return from sell the loser is more than that from buy the winner. This indicates that Taiwan’s electronic stocks get “the winner is keeping on upping and the loser is on downing.” Moreover, when considering size effect, the first strategy still gets the negative excess return but in small size, the effect is not as obvious as what is in large or median size. On the other hand, to buy the winner portfolio shows it will produce positive abnormal return when buying the small or median ones; however, it is not significant in large ones. To sell the loser, it will get the excess return whatever size it is, especially when selling the large-size loser. There is a big finding in size effect, the evidence shows Taiwan’s electronic stocks get “the winner is keeping on upping and the loser is on downing.” In result, the invest strategies are that it will get profits in whatever size it is while using the first strategy; when only buying winner portfolio, it is more possible to get profits in small and median size; when only selling the loser portfolio, it is more profitable in large size. 第一章 緒論 1 1.1 研究背景 1 1.2 研究動機與目的 2 1.3 研究流程與架構 4 第二章 文獻探討 6 2.1 理論依據 6 2.2 國外相關實證文獻 9 2.3 國內相關實證文獻 15 第三章 研究方法 24 3.1 研究期間與選樣標準 24 3.2 研究模式的選取 27 3.3 研究設計 30 3.4 研究假設與統計檢定 37 3.5 研究限制 43 第四章 實證結果與分析 44 4.1 市場模式之建立 44 4.2 未控制公司規模前的實證結果 48 4.3 控制公司規模後的實證結果 52 第五章 結論與建議 66 5.1 結論 66 5.2 建議 67 參考文獻 69
