Mestrado em Finanças<br>Este projeto consiste num relatório de avaliação da Corticeira Amorim S.G.P.G, S.A., que segue o formato recomendado pelo CFA Institute. Inclui uma especialização no estudo da abordagem Sum of Absolute Rank Differences (SARD) na seleção do grupo de empresas para a avaliação através dos múltiplos. Apenas informação pública até 31 de dezembro de 2018 foi utilizada neste relatório.
O FCFF foi usado como principal proxy para estimar o preço-alvo da COR de €10.9 por ação, representando um potencial positivo de 21%, de 31 de dezembro de 2018, levando a uma recomendação de compra.
COR é a líder de mercado no negócio das rolhas de cortiça com uma quota de mercado de 44%. A Cork Stoppers BU é a unidade de negócio que contribui mais para as vendas totais da COR. Entre 2018-23, a empresa deverá aumentar as vendas totais em 4.4% CAGR, principalmente devido ao aumento do consumo do vinho e da tendência de premiumization.
O preço-alvo da COR foi novamente calculado através da avaliação dos múltiplos, mas com uma diferença no processo de seleção do grupo de empresas, onde a abordagem SARD foi implementada com o intuito de se obter resultados mais precisos. No entanto, o preço-alvo obtido com esta alternativa não suporta a nossa recomendação base. Ficou demonstrado que este método nem sempre é a alternativa mais eficiente no processo de seleção de empresas comparáveis e pode não funcionar muito bem quando é aplicado a indústrias dominadas por poucos concorrentes.<br>This project is an Equity Research of Corticeira Amorim S.G.P.S., S.A. following the format recommended by the CFA Institute. Includes a specialization on the study of the Sum of Absolute Rank Differences (SARD) approach when selecting a peer group of companies for the valuation through multiples. Only public information until December 31st, 2018 was used in this report.
The FCFF was used as the main cash-flow proxy to estimate COR's price target of €10.9/sh, representing an upside potential of 21%, from December 31st, 2018, leading to a BUY recommendation.
COR is the market leader in the cork stoppers business with 44% market share. The Cork Stoppers BU is the business unit that contributes the most for COR's total sales. From 2018-23 the company should increase total sales by 4.4% CAGR, mainly due to the increase in wine consumption and premiumization trend.
COR's price target was once again computed through the multiples valuation, but with a difference regarding the selection process of the peer sample, where the SARD approach was implemented to reach more accurate results. However, the price target obtained with this alternative does not support the base recommendation. It was demonstrated that this method is not always the most effective alternative when choosing peer companies and it may not work that well when it is applied in industries dominated by a few players.<br>info:eu-repo/semantics/publishedVersion

Full textAbstract:
Sand production is a complex problem that has plagued the oil and gas industry for decades, leading to reduced productivity, wellbore instability, equipment failure and expensive sand control and management techniques. Therefore, a reliable prediction of the potential of a formation to produce sand as well as the mass and volume of the sand produced is required for an appropriate and economically effective sand management. In this thesis a novel approach (yield energy model) to predict the potential of formation to produce sand and to quantify the mass of sand produced around yielded wellbore region based on energy dissipation is presented. During drilling and hydrocarbon production, yield and fragmentation of rock around a wellbore may occur when the rock is exposed to stresses which exceed its failure criterion, creating yield zone and hence the potential for instability and sand production. Generally, in brittle rocks, grains are deformed elastically with increasing stress, storing strain energy in the process. The stored strain energy is dissipated during failure, some of which is available for the fragmentation of the rock along failure surfaces. It is argued that the major source of sand production in competent rock is associated with the debris created by slippage along shear fractures in the yielded zone along perforation wall. The potential for sand production and the mass or volume of the sand created around the yield zone is predicted by quantifying the reduction in strain energy stored in the rock as its yields around a completion on removal of completion fluid and the imposition of drawdown. The resultant sand then becomes available as a source for sand production. The yield energy model has been applied to assess the potential of several reservoir samples to produce sand and also quantify the mass of the sand produced as a result of formation instability caused by drilling and hydrocarbon production in a field specific manner. Results from laboratory testing of representative samples and field data has been utilised as input parameters. The extent of the failed zone, the sand production potential and the mass of debris have been analysed as a function of mud weights, drawdown pressures and production rates. The impact of unique production performance of different horizons on formation stability has been accounted for by employing deliverability expressions. The results have been assessed with regards to field observations and were found to be consistent.

Full textAbstract:
Levees provide protection for vast amounts of commercial and residential properties. However, these structures degrade over time, due to the impact of severe weather, sand boils, subsidence of land, seepage, etc. In this research, we focus on detecting sand boils. Sand boils occur when water under pressure wells up to the surface through a bed of sand. These make levees especially vulnerable. Object detection is a good approach to confirm the presence of sand boils from satellite or drone imagery, which can be utilized to assist in the automated levee monitoring methodology. Since sand boils have distinct features, applying object detection algorithms to it can result in accurate detection. To the best of our knowledge, this research work is the first approach to detect sand boils from images. In this research, we compare some of the latest deep learning methods, Viola Jones algorithm, and other non-deep learning methods to determine the best performing one. We also train a Stacking-based machine learning method for the accurate prediction of sand boils. The accuracy of our robust model is 95.4%.

Cette thèse est divisée en trois parties. Dans une première partie, on donne une description nouvelle des points récurrents par chaînes d'un système dynamique comme ensemble d'Aubry projeté d'une barrière ultramétrique. Cette approche permet de munir l'ensemble des composantes transitives par chaînes d'une structure d'espace ultramétrique expliquant leur topologie totalement discontinue, et de retrouver un théorème célèbre de Charles Conley concernant l'existence de fonctions de Lyapunov décroissant strictement le long des orbites non-récurrentes par chaînes. Dans une deuxième partie, on développe une théorie d'Aubry-Mather pour les homéomorphismes d'un espace métrique compact. On introduit dans ce cadre un ensemble d'Aubry métrique, puis topologique, ainsi qu'un ensemble de Mañé. Ces notions, plus fines que la récurrence par chaînes, permettent de mieux comprendre les fonctions de Lyapunov d'un tel système dynamique. Dans une dernière partie, on montre un résultat général de densité de certains contre-exemples au théorème de Sard pour lesquels l'ensemble des points critiques est un arc topologique et on donne des applications dynamiques de ce résultat. Celles-ci sont liées à des problèmes d'unicité, à constantes près, des solutions KAM faibles (ou solutions de viscosité) de certaines équations d'Hamilton-Jacobi.

Mestrado em Contabilidade, Fiscalidade e Finanças Empresariais<br>O seguinte trabalho tem como objetivo a avaliação das ações da Sporting Clube de Portugal - Futebol, SAD (Sporting SAD). Para tal, foi feito um estudo da indústria do futebol, um segmento da indústria desportiva que tem vindo a atrair cada vez mais adeptos/espectadores assim como a gerar mais receitas. No entanto, quanto ao caso em estudo, a Sporting SAD não tem apresentado uma estrutura de capital sólida, estando muito dependente tanto dos resultados desportivos como da venda de jogadores para atingir bons resultados financeiros.
Esta avaliação foi realizada à data 30/06/2017. De referir que quaisquer informações ou acontecimentos relacionados com a Sporting SAD ou com o sector após maio de 2018 não foram considerados no nosso estudo.
Esta avaliação foi feita seguindo o método Discounted Cash Flow tendo-se optado pela abordagem dos Free Cash Flow to Firm (FCFF). De forma a obter uma recomendação mais robusta e sustentada, a avaliação foi complementada com uma metodologia de avaliação relativa, o Método dos Múltiplos.
O resultado obtido foi a subvalorização das ações uma vez que o preço histórico da ação é de 0,62€ e o target price obtido foi de 0,92€ (FCFF), apresentando um upside potencial de 47,96% que leva a uma recomendação final de compra de ações da Sporting SAD.

Full textAbstract:
As a proactive, information-based policing approach, problem-oriented policing emphasizes the use of crime analysis techniques in the analysis of the underlying causes of the problems that police deal with. In particular, analysis applications can be powerful tools for criminal investigation, such as crime reconstruction, profiling, IAFIS, VICAP, and CODIS. The SARA Model represents a problem-solving strategy of problemoriented policing. It aims to address the underlying causes of the problems and create substantial solutions. However, implementing problem-oriented policing requires a significant change in both the philosophy and structure of police agencies. Not only American policing but also the Turkish National Police should consider problem-oriented policing as an alternative approach for solving criminal activities.

Full textAbstract:
<p> Determining the hydraulic properties of aquifer and aquitards (K,T,and S) is very important in hydrogeologic studies. These parameters can be identified by methods such as laboratory permeability and borehole hydraulic response test. Because these approaches are sometimes costly, involving drilling test holes, and often may not be feasible, numerical modeling approaches can be considered as alternatives. In the following study, numerical modeling is applied to simulate groundwater flow system to determine the hydraulic properties of a weathered/fractured zone in a valley located within the Appalachian Plateau Geomorphic Province. The Appalachian Plateau is characterized by relatively flat-laying but intensely eroded bedrock, comprising cyclical sequences of Pennsylvanian age sedimentary bedrock dominated by sandstone, siltstone, shale, coal, claystone, and occasionally limestone. Fractured/weathered sandstone is potentially the main bedrock groundwater transmitting formation. The extent of fractures is from the ground surface to about 120-150 ft (or roughly 30-40m) under the ground surface. The main groundwater flow occurs from within the intergranular pore space through fractures and along bedding planes of the bedrock. </p><p> The water level at a perennial stream in the valley can be considered as the phreatic ground-water level. Therefore, the elevation points along this stream may serve as model calibration points. Because the outflow from the valley is almost entirely via the creek, and creek water represents the groundwater level all along the valley, the model is calibrated and verified by the creek water elevations and the amount of water discharging through the valley. The site- specific hydrogeologic interpretation and evaluation technique presented in this study may be very well applicable to the significant portions of the Allegheny Plateau with similar geomorphologic, tectonic and lithologic characteristics.</p><p> </p>

Full textAbstract:
Biblical interpretation in the contemporary context of globalisation faces a variety of challenges. This thesis addresses the challenges presented to the discipline by the incorporation of poststructuralism, postcolonialism, and liberation theologies, particularly the problem of interpretive ghettoisation and the ethics of contemporary biblical interpretation. It proposes one possible answer to the question of how the field of biblical hermeneutics can move beyond the segregation passively encouraged by subjectivity and self-determination toward the integration of academic and vernacular hermeneutics in the interests of justice for the dominated and the reconstitution of the dominant. This thesis first presents the interpretive theories of Edward W. Said, addresses the major criticisms of his work, and proceeds to discuss the adaptation of his concept of contrapuntal reading to the interpretation of biblical texts. Second, it presents a survey of current work in the field which attempts to overcome the gap between academic and vernacular hermeneutics and critiques these approaches in light of Said’s concepts. Third, it presents the book of Job as an appropriate context in which to explore the possibilities of contrapuntal hermeneutics. This section analyses various academic and vernacular interpretations of the book of Job and places these interpretations in contrapuntal dialogue over the course of three chapters. The first of these chapters explores the possibilities for dialogue between those interpretations that view suffering as a key theme in the book and those that do not; the second chapter explores interpretations of the book of Job and the issue of suffering in various Euro-North American psychological contexts and in various African contexts of HIV/AIDS; and the third chapter juxtaposes academic and vernacular interpretations of the book of Job in various Asian contexts. Finally, the study closes with an argument for pedagogical reform based upon the ethical and interpretive insights of contrapuntal hermeneutics.

É extremamente comum que o solo de uma determinada região não tenha os parâmetros geotécnicos favoráveis a implementação de projetos de pavimentação e fundações. Com o passar do tempo, o homem ocupou praticamente todos os locais onde as características do solo são favoráveis à construção civil, principalmente nos grandes centros urbanos, restando os locais que desafiam os projetistas a fazerem obras de baixo custo e qualidade técnica. Com intuito de solucionar este problema, vários trabalhos estão sendo desenvolvidos através da técnica de melhoramento ou estabilização de solos com agentes cimentantes. Deste modo, o presente trabalho teve como objetivo validar uma nova abordagem para a obtenção de parâmetros de resistência ao cisalhamento de uma areia artificialmente cimentada. Para aplicação desta abordagem, utilizou-se resultados de compressão simples e diametral, sendo estes comparados com os resultados obtidos a partir de ensaios de compressão triaxial consolidados e drenados com as mesmas características dos ensaios de compressão não confinada. Com o intuito de enriquecer o conhecimento sobre o assunto, também foram aplicados outros modelos de previsão de resistência ao cisalhamento, tais como, o critério de ruptura de Griffith (1921) e o modelo experimental de Mitchell (1981). Para isto, o solo utilizado foi uma areia de granulometria fina com adição de Cimento Portland CPV-ARI, com três diferentes porcentagens de cimento em relação a massa de solo seco (3, 5,1 e 8,6) e, para tempos de cura de 03, 07, 28 e 90 dias. Baseados nos resultados obtidos através deste trabalho, concluiu-se que: quanto ao comportamento tensão-deformação, os ensaios apresentaram pico de resistência bem definido com comportamento de material rígido e queda acentuada da resistência após a ruptura; quanto a utilização da nova abordagem proposta, os parâmetros de resistência do modelo quando comparados com os resultados obtidos pelos ensaios triaxiais foram satisfatórios, deste modo validando esta metodologia. O emprego da teoria de Griffith e do modelo de Mitchell, não apresentaram resultados com a mesma qualidade obtida pela nova abordagem proposta.<br>It is extremely common that the soil of a particular region does not have the favorable geotechnical parameters for implementing paving and foundations projects. With the passage of time men has occupied virtually all locations where soil characteristics are favorable for constructions, especially in large urban centers, leaving the places that challenge engineers to design works of low cost and technical quality. In order to solve this problem, several studies are being developed through soil improvement and stabilization technique with cementing agents. Thus, the present study aimed to validate a new approach to obtain shear strength parameters of an artificially cemented sand. To apply this approach, results of unconfined compression tests were used, which were compared to the results obtained from consolidated and drained triaxial compression tests, with the same characteristics of the unconfined compressive tests. In order to enrich the knowledge on this subject, other models were applied to predict parameters of resistance, such as the Griffith (1921) failure criterion and the experimental model of Mitchell (1981). The soil used was a fine grained sand with addition of Portland cement CPV-ARI, with 3.00, 5.06 and 8.60 percentage of cement in relation to the mass of dry soil at curing times of 03, 07, 28 and 90 days. Based on the results obtained through this work, it was concluded that the use of the new approach proposed is valid because the strength parameters of the model when compared with the results obtained by the triaxial tests were satisfactory. The use of the Griffith theory and Mitchell model did not obtain results with the same quality obtained by the new approach proposed. Regarding the stress-strain behavior, the triaxial tests showed peak strength with well-defined behavior of rigid material and sharp drop in resistance after the rupture.

Full textAbstract:
Ecological evaluation techniques have been used to classify or evaluate the relative conservation worthiness of a portion of the Eastern Cape coastal zone from Cannon Rocks to Port Alfred. A system-based approach, using a basic GIS, was used to compare three aspects of the coastal zone. Two existing planning documents (EMATEK/s Coastal Vegetation Importance Rating plan and CPA's Cape Coastal Conservation plan) were statistically compared - based primarily on the size and number of the landscape fragments (environmental criteria polygons). The resultant plan, an Intermediate Sensitivity Class map, was further integrated with the biophysical aspect of the coastal zone - coastal dunes. The final map is the product of these overlays to be used as a-working overlay for coastal zone decision-making. This is an Environmental Sensitivity map, which has no particular direct reference to any particular biophysical criteria, which categorizes the coastal zone according to the environmental sensitivity or conservation worthiness of the site. The categories are listed according to a sliding-scale of sensitivity or worthiness. There is, however, it strong association between the final map and the vegetation status of the coastline, as a direct result of the vegetation rating map and indirectly from the perception based coastal conservation plan. The formation of most assessment or evaluation plans are based on the vegetation status of the area. This map can be overlayed over the particular stretch of the coastline which it covers and the particular conservation status noted. There are numerous techniques available for assessment and evaluation each having their own specific merits and advantages. This plan, however, is a first attempt at integrating other specific plans into a single working document for the coastal zone manager.

Full textAbstract:
Synthetic Aperture Radar (SAR) imaging is a well-known technique in the domain of remote sensing, aerospace surveillance, geography and mapping. To obtain images of high resolution under noise, taking into account of the characteristics of targets in the observed scene, the different uncertainties of measure and the modeling errors becomes very important.Conventional imaging methods are based on i) over-simplified scene models, ii) a simplified linear forward modeling (mathematical relations between the transmitted signals, the received signals and the targets) and iii) using a very simplified Inverse Fast Fourier Transform (IFFT) to do the inversion, resulting in low resolution and noisy images with unsuppressed speckles and high side lobe artifacts.In this thesis, we propose to use a Bayesian approach to SAR imaging, which overcomes many drawbacks of classical methods and brings high resolution, more stable images and more accurate parameter estimation for target recognition.The proposed unifying approach is used for inverse problems in Mono-, Bi- and Multi-static SAR imaging, as well as for micromotion target imaging. Appropriate priors for modeling different target scenes in terms of target features enhancement during imaging are proposed. Fast and effective estimation methods with simple and hierarchical priors are developed. The problem of hyperparameter estimation is also handled in this Bayesian approach framework. Results on synthetic, experimental and real data demonstrate the effectiveness of the proposed approach.

Thesis (MA)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: Children with specific learning disability (SLD) struggle with reading, spelling and/or writing, and tend to have poor narrative skills (Fey, Catts, Proctor-Williams, Tomblin & Zhang, 2004; Scanlon, 2013). Although learners with SLD mostly use grammatical sentences after discharge from conventional speech-language therapy, they often still struggle with creating narratives and find comprehension tasks challenging. For this study, I chose an action research design (McNiff & Whitehead, 2013). I used a lesser known therapy approach with some of these learners, in an attempt to ascertain whether kinetic methods of teaching language can improve their narrative skills. The research question posed was: What changes in narrative skills (if any), measured in terms of micro and macro structure, are brought about by the Sandtray Play Approach (STPA) in first language (L1) Afrikaans-speaking Grade 3 learners with SLDs?
I used the STPA with four L1 Afrikaans-speaking Grade 3 boys with SLD over a course of six weeks (on average two therapy sessions per week). During each session, they each choose a variety of miniature objects with which they individually built a so-called “Sandworld” in their own sandtray. After each Sandworld was built, the boys took turns telling their story and listening to those of the other group member. After each narration, each listener made one positive comment and asked one question about the story. During the intervention period, I regularly presented mini-sessions teaching the participants how to create, improve and expand their narratives. The Language in Multilingual Society: Multilingual Assessment of Narratives (LITMUS: MAIN-Afrikaans) (Gagarina, Klop, Kunnari, Tantele, Valimaa, Baluciuniene, Bohnacker, & Walters, 2012) was used to analyse pre- and post-intervention narratives in terms of story structure components; (in)completeness of episodes; mean length of utterance (in words); and use of subordinating and co-ordinating conjunctions, conjunctive adverbs and internal state terms. The pre- and post-intervention results of the four boys in the experimental group were compared to those of four boys who did not receive any STPA intervention and who formed the control group. All eight participants had been clinically diagnosed as presenting with an SLD. Comparisons of the LITMUS: MAIN-Afrikaans scores indicated inter-group differences: Post-intervention, the experimental group used a higher number of story structure components, internal state terms, words, and utterances (those linguistic aspects introduced and practised during STPA intervention) than the control group. The experimental group’s Sandtray narratives also increased in multiple areas of structural complexity – e.g., in the use of conjunctive adverbs; subordinating and co-ordinating conjunctions; and embedding.
These results have implications for speech-language therapy practice, showing that the STPA is potentially a valuable resource for teaching narrative skills to learners with SLD, and that positive changes can be observed in as little as six weeks. The STPA has been used in Europe with learners with hearing or learning impairment and with mainstream learners. In the South African context, it appears only to have been used to teach oral language use to deaf learners; and no South African studies on the use of the STPA for narrative skill development could be traced. This study was the first of its kind and indicated that using the STPA can assist Speech-Language Therapists in developing narrative skills of children with atypical language development.<br>AFRIKAANSE OPSOMMING: Kinders met spesifieke leergestremdheid (SLG) sukkel met lees, spelling en/of skryf, en neig om swak narratiefvaardighede te hê (Fey, Catts, Proctor-Williams, Tomblin & Zhang, 2004; Scanlon, 2013). Alhoewel leerders met SLG meestal grammatikale sinne gebruik ná ontslag uit konvensionele spraak-taalterapie, sukkel hulle steeds gereeld met narratiefproduksie en begripstake. Vir hierdie studie het ek gekies om ‘n aksienavorsingsmetode (McNiff & Whitehead, 2013) te gebruik. Ek het ‘n minder bekende terapiebenadering met sommige van hierdie leerders gevolg, in 'n poging om vas te stel of kinetiese metodes van taalonderrig hulle narratiefvaardighede kan verbeter. Die navorsingsvraag was: Watter veranderinge in narratiefvaardighede (indien enige), gemeet in terme van makro- en mikrostruktuur, word teweeg gebring deur die Sandbak-Speelbenadering (SBSB) in eerstetaal- (T1) Afrikaanssprekende Graad 3-leerders met SLG?
Ek het die SBSB met vier T1 Afrikaanssprekende Graad 3-seuns met SLG oor ses weke gebruik (gemiddeld twee terapiesessies per week). Tydens hierdie sessies het elkeen ‘n verskeidenheid miniatuur voorwerpe gekies waarmee elkeen individueel ‘n sogenaamde “Sandwêreld” in hulle eie sandbakkie gebou het. Nadat elke Sandwêreld gebou is, het die seuns beurte geneem om hulle storie te vertel en na die stories van die ander groeplede te luister. Nadat elke storie vertel is, het elke luisteraar een positiewe punt van kommentaar oor die storie gelewer en een vraag oor die storie gevra. Gedurende die intervensietydperk het ek gereeld mini-sessies aangebied om die deelnemers te leer hoe om narratiewe te skep, te verbeter en uit te brei. Die Language in Multilingual Society: Multilingual Assessment of Narratives (LITMUS: MAIN-Afrikaans) (Gagarina, Klop, Kunnari, Tantele, Valimaa, Baluciuniene, Bohnacker, & Walters, 2012) is gebruik om voor- en ná-intervensie-narratiewe te ontleed in terme van storiestruktuurkomponente; (on)volledigheid van episodes; gemiddelde lengte van uiting (in woorde); en die gebruik van onderskikkende en neweskikkende voegwoorde, verbindingsbywoorde en interne toestand-terme. Ek het hierdie tellings vergelyk met dié behaal deur 'n kontrolegroep (vier manlike klasmaats van die eksperimentele groep). Ek het ook 'n seleksie van drie verteenwoordigende sandbaknarratiewe per eksperimentele groepdeelnemer in terme van hierdie metings geassesseer Al ag deelnemers is klinies gediagnoseer met SLG.
Vergelykings van die LITMUS: MAIN-Afrikaans-tellings het inter-groepsverskille aangetoon: Die eksperimentele groep het ná intervensie ‘n groter aantal storiestruktuurkomponente, interne toestand-terme, woorde en uitinge (d.i. daardie linguistieke aspekte wat bekendgestel en geoefen is tydens SBSB-intervensie) gebruik as die kontrolegroep. Die eksperimentele groep se sandbaknarratiewe het ook toegeneem in terme van veelvuldige areas van strukturele kompleksiteit – byvoorbeeld in die gebruik van verbindingsbywoorde, onderskikkende en neweskikkende voegwoorde, en inbedding.
Hierdie resultate het implikasies vir spraak-taalterapiepraktyk: Dit toon aan dat die SBSB potensieel ‘n waardevolle hulpbron is vir die leer van narratiefvaardighede aan leerders met SLG, en dat positiewe veranderinge in so min as ses weke waarneembaar is. Die SBSB word in Europa met leerders met gehoor- of leergestremdheid gebruik asook met hoofstroomleerders. In die Suid-Afrikaanse konteks is dit skynbaar nog slegs gebruik om gehoorgestremdes te leer praat; geen Suid-Afrikaanse studies oor die gebruik van die SBSB vir narratiefvaardigheidsontwikkeling kon gevind word nie. Hierdie studie was die eerste van sy soort en toon aan dat die gebruik van die SBSB Spraak-Taalterapeute kan help om narratiefvaardighede te ontwikkel in kinders met atipiese taalontwikkeling.

Manifolds usually consist of metallic, rectangular base bodies into which lines are inserted by means of drilling, thus logically linking the built-on or built-in valves according to the hydraulic circuit diagram. Using additive manufacturing methods, additional degrees of freedom can be used in the design of manifolds, resulting in further benefit in hydraulic drives and their controls. The challenge is not only to understand and apply additive manufacturing technology, but also to align the entire value chain with it.

Full textAbstract:
The Ground-Based Synthetic Aperture Radar (GB-SAR) is a relatively new technique,
which in the last ten years has gained interest as deformation measurement and
monitoring tool. The GB-SAR technique is based on an imaging radar-based sensor, which
o ers high sensitivity to small displacements, in the region of sub-millimetres to
millimetres, long-range measurements, which can work up to some kilometres, and massive
deformation measurement capability. These features confer to the GB-SAR technique
interesting advantages with respect to other point-wise deformation measurement
techniques.
The process of estimating deformation from the GB-SAR data is not straightforward:
it requires complex data processing and analysis tools. This dissertation is focused on
these tools, covering the whole deformation estimation process. This thesis collects the
main research results achieved on this topic during my work at the Active Remote Sensing
Unit of the Institute of Geomatics. Two di erent approaches for measuring deformation
with GB-SAR data are described and discussed. The irst one is the interferometric
approach, based on the exploitation of the phase component of the GB-SAR data, which
is the commonly used GB-SAR method. The second one is a non-interferometric approach,
which exploits the amplitude component of the GB-SAR data, o ering an interesting
alternative way to exploit the GB-SAR data.
This dissertation has two main objectives. The first one is presenting, step by step, a
complete interferometric GB-SAR procedure for deformation measuring and monitoring.
The second one is presenting two new algorithms, which represent the most innovative
part of this thesis. The first algorithm faces the phase unwrapping problem, providing an
automatic solution for detecting and correcting unwrapping errors, which is called 2+1D
phase unwrapping. The second algorithm is the base of the above mentioned non-
interferometric approach, which overcomes some of the most critical limitation of GB-SAR
interferometry, at the expense of getting less precise deformation estimates.
The dissertation is divided in 6 chapters. The first one is the introduction, while the
second one provides an overview of GB-SAR interferometry, introducing the main aspects
that are the basics of the subsequent chapters. Chapter 3 describes a complete GB-SAR
processing chain. Chapters 4 and 5 contain the most original part of the dissertation, i.e.
the 2D+1 phase unwrapping algorithm, and the non-interferometric approach. Finally, in
Chapter 6 the conclusions are discussed and further research is proposed.<br>El radar terrestre d’obertura sintètica (GB-SAR) és una tècnica relativament nova
que, en els últims deu anys, ha guanyat interès com a eina per a mesurar i monitorar
deformacions. La tècnica GB-SAR es basa en un sistema radar amb capacitat per
proporcionar imatges, que ofereix una alta sensibilitat a petits desplaçaments, d’ordre
mil·limètric o submil·limètric, que és capaç de mesurar a llargues distàncies (alguns km)
i que té una alta capacitat per fer mesures massives. Aquestes característiques donen a la
tècnica interessants avantatges respecte a altres tècniques clàssiques de mesura de
deformacions, típicament basades en mesures puntuals.
Derivar mesures de deformació a partir de dades GB-SAR no és un procés senzill, ja
que requereix uns procediments complexos de processat i anàlisi de dades. Aquesta tesi es
centra en aquests processos. Aquesta tesi recull alguns dels resultats més destacats de la
investigació que he desenvolupat sobre aquest tema a la unitat de Teledetecció Activa de
l'Institut de Geomàtica. Al llarg del document es descriuen dues aproximacions diferents
per mesurar deformacions amb GB-SAR. Una es basa en la explotació de la tècnica de la
interferometria, és a dir explotant la component de la fase de les imatges GB-SAR: és la
tècnica GB-SAR usada habitualment. La segona, anomenada tècnica no-interferomètrica,
es basa en la component de l’amplitud de les dades GB-SAR i ofereix una interessant
alternativa a la primera.
La tesi acompleix dos objectius principals. En primer lloc presenta un procediment
complet per la mesura i monitoratge de deformacions mitjançant interferometria GB-SAR.
En segon lloc, descriu dos nous algorismes que resolen problemes específics de la
interferometria clàssica aplicada al GB-SAR i que representen la part més innovadora
d’aquesta tesi. El primer algorisme aborda un dels problemes oberts de la interferometria,
el phase unwrapping, proposant un mètode automàtic per detectar-ne i corregir-ne els
errors. El segon algorisme proposa un nou mètode per a l'explotació de les dades GB-SAR
per mesurar deformacions sense utilitzar la interferometria.
La estructura de la tesi consisteix en sis capítols. Després de la introducció, el Capítol
2 proporciona una visió general de la interferometria GB-SAR, introduint els conceptes
principals utilitzats en la tesi. En el tercer capítol es descriu una cadena de processament
basada en GB-SAR interferomètric. Els capítols quart i cinquè contenen la part més
original de la tesi: l'algorisme de phase unwrapping i el mètode no-interferomètric per la
mesura de deformacions. Finalment, es discuteixen les conclusions principals i es proposen
futures línies d’investigació.

Full textAbstract:
The motivation for the study had its origin in the fact that sexual abuse in South Africa seems to be a formidable problem which has a detrimental effect on the adolescent’s development and functioning. Social workers have to deal with sexual abuse often and do not always have the necessary programmes and skills acquired to follow through therapeutic intervention with these victims. Therefore this study focused on the development, implementation and evaluation of a narrative social work intervention programme where sand play techniques were integrated in the narrative process.
The research problem formulated was that many adolescents suffer from the effects of sexual abuse and therefore the aim of the study was to develop and evaluate a narrative social work intervention programme for adolescent survivors of sexual abuse. The study served to broaden the body of social work knowledge by means of meaningful quantitative and qualitative enquiry. Quantitative data were obtained through the use of questionnaires and qualitative data through the use of combined sand play and narratives as approaches. Four (4) participants were included in a series of 10–15 sand play sessions. Only the data of one (1) participant was used for data–analysis. Two (2) sessions were used for general assessment and building of therapeutic relationship and an additional session was used for an interview with the parent(s).
The researcher undertook mixed method research where the quantitative and qualitative approaches were combined into the research methodology of the single study. Intervention research was used as basic methodology. Purposive sampling was used in the selection of the research subject for this study. Collected data was analyzed according to Tesch’s approach to qualitative data analysis (Creswell, 1994).
The researcher applied the developed social work intervention programme with four (4) adolescent participants who had allegedly been sexually abused. The sand play sessions were audio recorded and evaluated by means of data analysis.
The findings of this study emphasized the psycho–social impact of sexual abuse on survivors of sexual abuse. This thesis reflects the contribution and impact that the social work intervention programme had on the adolescent survivor of sexual abuse. This programme was found to be a valuable tool that can be used in intervention with adolescents and could add to the knowledge of social workers and other professionals working with the survivors of sexual abuse.
The research can be recognized as a positive demonstration of the value of a narrative social work intervention programme. Recommendations regarding future implementation of the narrative social intervention programme have been made.<br>Thesis (Ph.D. (Social Work))--North-West University, Potchefstroom Campus, 2012.

Full textAbstract:
This thesis examines the work of two of the twentieth century’s foremost cultural figures, the Palestinian-American literary critic Edward Said (1935-2003) and the Palestinian poet Mahmoud Darwish (1941-2008), and focuses specifically on the formulation and representation in their respective work of the theme of identity. It explores the depictions of this concept in their writing; comparing and contrasting their personal viewpoints on the various facets of their own identity as Palestinian Arabs and cosmopolitan global citizens expressed through their chosen literary medium, prose for Said and poetry for Darwish. At the same time, this analysis of the creative writing of these two authors will serve to shed light on the complex and ongoing process which is involved in identity formation and maintenance, and conceptualization of the self. Said and Darwish’s multi-conceptualisations of self-identity take place in Chapter Three, which is divided into seven zones of self-identity. Their understanding of self-identity is observed through the spaces of their names, language, family relationships, friendships, ethnicities, nationalism, hybrid identities, and cosmopolitanism. The concept of post-Nakba and Naksa literature maps the critical developments in evaluations of Arabic literature and, more particularly, Palestinian literature. The understanding of Palestinian cultural context requires an adequate assimilation regarding the impact of Nakba and Naksa in Palestinian literature, linked strongly with the general impact of Nakba in all Arab literature. The thesis begins by establishing the major socio-political, cultural and historical contexts which shaped the lives and work of Said and Darwish. Then using an innovative theoretical framework which draws on elements of post-colonial theory Said’s own contrapuntal technique and close textual analysis, the thesis explores a number of key facets pertaining to identity construction which it can be argued are of particular relevance to the Palestinian case. These include trauma, collective cultural memories, displacement, the Diasporic experience and the dream of return. At the same time, the thesis reveals how whilst both Said and Darwish remained dedicated to the Palestinian cause they adopted a cosmopolitan identity which was reflected in their respective work and its identification with diverse groups of oppressed peoples.

Full textAbstract:
Peat moorlands represent a nationally significant carbon store. Wildfires in peat moorlands release CO2 into the atmosphere, reducing the carbon store and burn into the seed bank preventing vegetation recovery. Burned areas of bare peat remain, known as ‘burn scars’ which are eroded by freeze thaw and desiccation, then weathered by precipitation and wind to cause discolouration of the water supply. A technique for the systematic monitoring of peat moorland burn scars is essential for informing land management and moorland restoration. Satellite data enables peat moorland burn scars to be monitored at the landscape scale for operational services e.g. European Forest Fire Information System (EFFIS). However, in the UK cloud is highly problematic for optical satellites and thermal data provides only a short window of opportunity for active fire detection. This thesis provides a unique line of enquiry by exploring the potential of Synthetic Aperture Radar (SAR) intensity and Interferometric Synthetic Aperture Radar (InSAR) coherence for burn scar characterisation and persistence, using a multi-temporal and multi-sensor approach for degraded peat moorland. The Peak District National Park (PDNP) was selected because it is a marginal moorland environment, which experiences high rates of peat erosion and will experience more wildfires, based on future projections of increased temperature, due to global warming. Initial SAR intensity results for the Bleaklow 2003 burn scar showed a clear post-fire increase of 7 dB for burned peat bog when acquired under wet conditions. Post-fire, dry − wet InSAR pairs were characterised by vegetation removal caused by combustion within the burn scar area, whereas wet − wet InSAR pairs characterised the burn scar, but also degraded peat moorland caused by previous wildfires blurring the new burn scar perimeter. Intensity differed significantly with slope for the PDNP 2003 wildfires, reducing the effectiveness of the technique for characterising burn scars on slopes facing away from the sensor, although these wildfires showed no significant difference on coherence for the inland bare ground class. When using coherence as a burn scar discriminator, this research found that it is essential to acquire InSAR pairs immediately post-fire with B⊥ < 550 m. Using a combination of intensity and coherence data a multi-difference colour composite was produced and an ISODATA classification applied. Results were reclassified to produce a burned area map with an overall map accuracy of 94% and Kappa Coefficient of 0.69 covering the Bleaklow and Kinder 2003 burn scars. Burn scars < 6 km2 provided a persistently higher burned area intensity signal for up to six months after the wildfire but only 2 − 3 months for coherence. The smaller Edale burn scar (0.10 km2) was characterised by 2 − 3 dB greater intensity for the burned area over a year after the wildfire. The Edale 2008 case study showed that L-band PALSAR data is less sensitive to characterising peat moorland burn scars compared to C-band data. This study therefore strongly recommends C-band data for peat moorland burn scar characterisation and monitoring. Future research will explore the new C-band Sentinel-1 data which offers improved spatial resolution and repeat-pass time.

Dans la présente étude intitulée « Une approche transnationale des écritures des femmes ottomanes et françaises (européennes) au 19ème et au début du 20ème siècle » nous avons étudié les ouvrages et œuvres de femmes ottomanes et européennes autour de l’image du « harem » avec une approche transnationale féministe. La revendication de la thèse est que l’on ne peut ni parler d’une seule image du harem ni d’un type de récit de harem de femme ottomane, anglaise ou française. En replaçant ces ouvrages, classés dans la catégorie de « littérature de harem » au rang de la littérature mondiale, nous avons observé les différentes manières d’appréhender la lutte pour la libération de la condition féminine des femmes ottomanes comme autant de témoignages différents. D’autre part, nous avons mis en évidence, les interactions et la solidarité que les femmes féministes ottomanes et européennes ont mis en place, malgré les différences, de race, langue et religion pour leur lutte pour la condition féminine, dans un commun état d’esprit lié aux revendications de leur genre, du 19ème siècle au début du 20ème siècle<br>In this manuscript titled « A Transnational Approach to Literatures of Ottoman and French (European) Women Writers of 19th and Early 20th Centuries » works of Ottoman and European women writers gathered around the image of « harem » are explored with a comparative and transnational feminist method. Their work is analyzed in a non-Eurocentric, transnational, multi-cultural and multi- lingual, global and systematic perspective divorced from discourses of male hegemony. The central argument of this manuscript is that there are multiple images for the East and hardly any type of European women’s narrative can serve as a prototype. In this study, narratives piled under the category « harem literature » are evaluated as part of the greater World Literature and arenas for contrasting testmonies of Ottoman Women’s Liberation Movement. Moreover, solidarity and interaction developed among Ottoman and European women are noted who had common gender-related problems next to differences due ethnicity, language and religion, in the 19th and early 20th centuries

Full textAbstract:
Cette thèse présente une méthode de reconstruction 3D de bâtiments à empreinte à angles droits et à toit plat par morceaux, à partir d'images interférométriques RSO (RADAR à synthèse d'ouverture) haute résolution en bande X provenant du capteur RAMSES (ONERA). De part l'acquisition en visée latérale et la nature électromagnétique de l'onde RADAR, les images RSO sont très différentes des images optiques et difficilement interprétables. C'est pourquoi, une analyse géométrique et phénoménologique des images RSO est tout d'abord effectuée. Cette analyse permet de comprendre l'origine des primitives utilisées lors de la reconstruction. Pour réduire le chatoiement, les images RSO sont tout d'abord filtrées. Le filtre non paramétrique mean shift est introduit en imagerie RSO et étendu à l'image de cohérence. L'extraction des primitives est ensuite effectuée grâce à des algorithmes basés sur la transformée de Hough. La méthode de reconstruction utilise la gestion d'hypothèses car l'ensemble des primitives extraites ne suffit généralement pas à décrire le bâtiment complètement. Pour cela le bâtiment est décomposé de façon hiérarchique par un ensemble d'éléments (façade, toit etc.). La gestion d'hypothèses permet de générer l'ensemble des hypothèses de bâtiments à partir des primitives extraites. Ensuite, les hypothèses générées sont validées ou rejetées par la détection des incompatibilités géométriques et interférométriques. Enfin, un classement des hypothèses validées est effectué. En perspective, les contributions apportées dans cette thèse sont mises en avant en montrant leur adaptabilité à d'autres données (polarimétrie, meilleure résolution).

Full textAbstract:
<p>The process of allocating necessary resources like clean water, fuel/energy and food have resulted in an unsustainable use of natural resources causing problems with Soil erosion, soil fertility, desertification, deforestation, eutrophication and global warming. The purpose of this study was to gain information on the functional design of a waste management system enabling the organic components of domestic waste to be processed as useful resources while at the same time allow them to be re-circulated. The main part of this study was carried out at the Kendu SDA Hospital in the Rachyonyo district in western Kenya. For the case of this study two main objectives where chosen. The first was to develop a principal technological solution using three classed “appropriate technologies” found suitable for the purpose namely biogas, ecological water treatment systems and slow sand filtration. The second was to further analyse each included technology to further develop their potential to fit the concept. Results from the pilot facilities where then to be retrieved from the actual component selection and construction process itself, with performance analysis left for future studies.</p><p>The main purpose of the biogas system study has been to evaluate the original ideas of overall concept, details, materials and construction methods. The 1 m3 biogas system has improved significantly during the development process and is today not far from an implementation, i.e. construction on a slightly larger scale. The biogas system developed during the project has proven to have potential for digestion of both latrine and kitchen waste. Using the two as fuel for the process does not only remove a problem – it grants several benefits.</p><p>The ecological waste water treatment system main objective was to design and construct a pilot SSF-wetland. Results show that the construction process for smaller scaled SSF systems is simple and does not require trained personnel or specialized equipment and that significant cost reduction can be made by using locally available materials.</p><p>The slow sand filtration sub system concept is called PT SCX and though still in the stage of development proved to have great potential concerning both efficiency and sustainability. The PT SCX comprises the advantages of slow sand filtration with further development of individual system solutions. It was adapted to enable both integration to the IWESS solution and stand alone installations purifying even highly turbid surface water sources to drinking water quality.</p><p>The result from the study confirms the suitability of the three included technologies, ecological waste water treatment, biogas and slow sand filtration to work in an integrated system called IWESS- Integrated Water Energy and Sanitation Solution. The combined subsystems can together with source separated sewage offer full resource recovery enabling recirculation of both nutrients and water. In addition the system can be designed as a net producer of renewable and emission free energy.</p>

Full textAbstract:
‘Teach these boys and girls nothing but Facts. Facts alone are wanted in life. Plant nothing else, and root out everything else’. This famous line from Charles Dickens’s Hard Times reflects an attitude that, it seems, still appears in some education programmes in Saudi Arabia. This thesis reports on a critical investigation into a teacher-training programme; the research broadening from solely investigating the programme at Department of Curriculum and Instruction at King Saud University, to a two strand examination, also considering the low status of art and art education in Saudi schools and society. The study particularly examined the effect of academic recognition on the programme by the Centre for Quality Assurance in International Education granted according to the standards of the American National Council of Teacher Education. Much of my research adopted participatory arts based methods, inviting participants’ expression of ideas through sets of activities during six months of fieldwork, using semistructured interviews, focus groups, and observation of some of the participants. The research is responsive to multiple stakeholder perspectives: students, student-teachers, faculty members, NCATE committees, Deanship of Quality and myself as researcher. Arts based participatory activities were used to examine the current situation of the teachertraining programme post-CQAIE recognition; connecting art education to individual development, changing perceptions, and general attitudes to art and art education, working towards improving society through art. It appears that the programme remains a conventional vocational course; objectives driven and operating largely along a 'banking concept of education' as described by Freire, with little consideration given to developing skill and students’ voices in the context of the teacher-training programme. Finally, this thesis posits a more progressive, holistic approach within the teacher-training programme, developing students’ skills and abilities and perhaps improving the perception of art and art education in the broader world beyond the institution.

Les communications cellulaires sont indispensables au bon fonctionnement des organismes multicellulaires, notamment pour s’adapter à un environnement changeant en permanence. Les cellules du système immunitaire n’échappent pas à cette règle mais les interactions entre cellules immunitaires restent peu connues et compliquée à étudier. La récente apparition des technologies de séquençage dites ‘cellules uniques’ représente une opportunité unique pour étudier ces communications. Dans cette thèse, différentes approches expérimentales et analytiques ont été développées pour étudier ces communications à une échelle de cellules uniques. Ces stratégies ont ensuite été appliquées à différents contextes pathologiques, incluant le COVID-19, la maladie d’Alzheimer ou une immunisation par des pathogènes inactivés, et ont permis d’identifier des voies de communications cellulaires jusqu’ici inconnues ou mal comprises. Néanmoins, l’efficacité de ces approches est limitée par l’absence d’informations sur la localisation des cellules et des travaux supplémentaires intégrant ce genre de données est essentiel pour aller plus loin dans la dissection des communications entre cellules immunitaires<br>Cellular communications are essential to the proper functioning of multi-cellular organisms, particularly in order to adapt to a constantly changing environment. The cells of the immune system are no exception to this rule, but the interactions between immune cells remain little known and complicated to study. The recent emergence of 'single cell' sequencing technologies represents a unique opportunity to study these communications. In this thesis, different experimental and analytical approaches have been developed to study these communications on a single cell scale. These strategies were then applied to different disease contexts, including COVID-19, Alzheimer's disease or immunisation with inactivated pathogens, and identified previously unknown or poorly understood cellular communication pathways. However, the effectiveness of these approaches is limited by the lack of information on cell location and further work integrating such data will be essential to go further in the dissection of immune cell communications

Full textAbstract:
A critical analysis of the implementation of the 'pay now, argue later' principle by SARS as provided by section 164 of the Tax Administration Act 28 of 2011: Abstract: The 'Pay Now, Argue Later' principle applies in income tax or value-added tax collection procedure after the South African Revenue Services has concluded an assessment in terms of the Tax Administration Act 28 of 2011 and found that an amount of tax is due and payable by the taxpayer. In terms of the 'pay now, argue later' principle, the taxpayer has to pay the assessed amount before being accorded an opportunity to raise any objections. The purpose of this paper is, to do an in-depth evaluation of the implications of the implementation of the 'pay now, argue later' principle by SARS. The implementation of the principle will be evaluated to determine if it is unjust, inequitable or unreasonable. In addition to the latter evaluation, the principle's shortfalls will be highlighted with the inclusion of a brief legal position in other countries. The paper acknowledges the existence of the principle, although the implementation thereof by SARS remains questionable and a source of controversy. The paper ultimately concludes that the 'pay now, argue later' principle, though constitutionally validated to a certain extent need to be revised. A balance has to be struck between the taxpayer's rights, public interest and SARS' powers in implementing the principle. A recommendation is therefore made to place the implementation thereof in the Tax Ombud in view of UK's Taxes Management Act where Commissioners resolve such disputes between taxpayers and the Inland Revenue Authority.

Limitation of interest deduction in South Africa: a suggested approach to the application of sections 31 and 23M of the Income Tax Act 58 of 1962 to debt and equity business financing methods. Abstract:
The South African income tax system acknowledges the financing of resident companies by a related non-resident company through the use of debt and equity. However, the use of debt financing method is a cause for concern to the South African Revenue Services as it results in the base erosion and profit shifting of taxable profits through mispricing and excessive interest deductions. Section 31 and 23M were inserted into the South African Income Tax Act 58 of 1962 to address excessive debt levels and interest deductions. The objective of this paper is to analyse the rationale behind the use of debt and equity financing methods. This paper will also discuss the application of both s 31 and s 23M. Due to the close connection of s 31 and s 23M to debt transactions, an approach on how the two sections can be applied is suggested. This paper finds that the provisions of both s 31 and s 23M are applicable to the same set of facts. The paper also finds that s 31 provisions are applied to determine if a company has excessive debts taking into account the arm's length principle while s 23M provisions are applied to limit interest deductions. The paper suggests that the legislature should provide guidance on the interplay of the two provisions and in the absence of any guidance, the provisions of s 31 should be applied first followed by the provisions of s 23M.

Full textAbstract:
Oil sand deposits are found at three depths; shallow, intermediate, and deep. Shallow deposits are processed by surface mining while deep deposits are processed using thermal extraction methods. There are currently no production methods to extract oil sand at intermediate depths. The motivation for this research is to demonstrate the technical applicability of methods to access oil sand that is too shallow for thermal extraction methods and too deep for economical surface mining.
This work consisted of developing a system concept as a method for accessing, fragmenting, and removing oil sand at intermediate depths. A technical analysis and a cost estimate were also performed. In addition, the applicability of a comparative methodology was demonstrated with case studies.
A key gap in the understanding of how to implement the system concept is tooling design and power requirements for fragmenting oil sand and interburden; and so a set of laboratory experiments was conducted to investigate the power required to cut oil sand. Oil sand blocks were formed from oil sand samples for the experiments. These blocks underwent various tests to examine their characteristics. Tests included: shear testing, extraction testing, porosity measurements, and scanning electron microscopy.
Lab-scale experiments were conducted in dry, wet, and frozen conditions in support of the fragmentation aspect of the system concept. Thermal imaging was used to qualitatively view temperature variation during the testing process and cutter wear was viewed using a digital microscope. Results were compared against a steady-state cutting model with recommendations for future work.

碩士<br>國立中興大學<br>土木工程學系所<br>105<br>Since Taiwan is located in the coastal area of wind rushing, it often has to face the problem with the damage of strong winds and sand drifting, especially when winter comes, the wind velocity is often up to 10m / s or more, so we have to take the importance of sand-drifting research seriously. Currently, it is rare to see the field of civil engineering using CFD to do the research of sand-drifting combined action on construction of embankment in our country. In this research, the main purpose is to design the construction of embankment and analyze different wind velocity, particle size, and the density of sand to study the amount of sand-drifting residues after strong winds blow over the construction of embankment, and determine its necessity and effectiveness.
In recent years, with the advance of hardware and software, by data processing and high speed arithmetic capability, using computational fluid dynamics (CFD), adopting FLUENT, and the experimental measurement data in the literature as a basic found of numerical simulation and experimental results. To let numerical simulation results and literature results use of comparative analysis, it verified the feasibility of using CFD in two-phase flow sand drifting, and then proceed the design of the embankment simulation. We can take the result that we got as reference for the continual works construction.

碩士<br>國立雲林科技大學<br>資訊管理系碩士班<br>92<br>Significant improvement of medical treatment makes people convince that most viruses can be controlled effectively and neglect their implicit danger. The nightmare made by SARS in the last summer reveals such a vivid example. The object of this study is to construct a computer system for investigating the behaviors of viruses (spread and adaptation of viruses) under different environments (temperature, humidity, acid/alkalinity, environment cleanness, environment energy and so on). An artificial world model for investigating the spread and adaptation of viruses with different fatality types of viruses, different type of spreading media, and different government policies was constructed.
It is extremely difficult and quite expensive, or even impossible, to investigate the above issues if we try to implement it on the real world (e.g., conduct experiments on people with real viruses). In the meantime, it is not easy to comprehend clinical experimental results. Moreover, it is illegal to perform physical human experiments. More important, people still have very limited knowledge of SARS viruses. Computer simulation and artificial worlds approach allow us to fill up this gap, as we can temporarily set aside the insufficient knowledge of SARS and step ahead the dilemma of difficulty in collecting real data so as to engage in a variety of experiments without interfering the real world.
