Text mining has become an established discipline both in research as in business intelligence. However, many existing text mining toolkits lack easy extensibility and provide only poor support for interacting with statistical computing environments. Therefore we propose a text mining framework for the statistical computing environment R which provides intelligent methods for corpora handling, meta data management, preprocessing, operations on documents, and data export. We present how well established text mining techniques can be applied in our framework and show how common text mining tasks can be performed utilizing our infrastructure. The second part in this thesis is dedicated to a set of realistic applications using our framework. The first application deals with the implementation of a sophisticated mailing list analysis, whereas the second example identifies the potential of text mining methods for business to consumer electronic commerce. The third application shows the benefits of text mining for law documents. Finally we present an application which deals with authorship attribution on the famous Wizard of Oz book series.

Through analysis of the site, and of the important historic precedents in the area of St. Andrew's, Manitoba, the project attempts to fill a void in the fabric of life of a rural community. Moreover, the project seeks to ameliorate the negative effects that sub-urbanization is having in the present, and will have in the future, upon the community of St. Andrew's. A community hall in a strategic location - at the junction of the historic Red River Heritage Parkway, and St. Andrews's Road - will increase the civic and community presence at the heart of the small town. Sited in relation to St. Andrew's Church, the St. Andrew's Rectory, and St. Andrew's Elementary, the proposed Community Hall will first of all provide a place for people in and outside the community to gather, be it for socials, dances, political meetings, or fall suppers. Secondly, the Community Hall will address the life of the Red River. A problem identified by the research was that new subdivisions within St. Andrew's fail to address the Red River. A Community Hall, which refocuses considerable attention towards river recreation, would increase the awareness of planners and other professionals so that St. Andrew's will be developed in ways which contribute to the fabric of life in St. Andrew's. To this end, the project supports the development of a descriptive, rather than prescriptive, park-like area along the banks of the Red River. Such a park would provide places for children and adults to seek out the river's edge for recreation, both in winter and in summer. Small hills will be enjoyed as sledding opportunities, while a concerted effort in cleaning and scraping the ice of the river will provide for public skating. Boat launches will be used in summer by visitors, and small shacks provided in both winter and summer for respite from the elements. The programme of the building will also support such activities. The main floor and mezzanine should be viewed as "formal," as they address the events of the community at large and ingrain themselves into the life of school, church, and town. The lower floor of the building, however, will have public washrooms, rentable rooms for boy scout meetings, floor hockey and the like, and a concession area. This lower level will address itself to the informal life of the community as embodied through the symbol of the Red River.

Ao contrário do homem, as cardiopatias de natureza hipóxica/isquêmica são pouco relatadas nos cães. Raros são os relatos de infarto agudo do miocárdio (IAM) nesses espécimes; entretanto, existem achados eletrocardiográficos que indicam hipóxia/isquemia miocárdica, como os desníveis (infra e supra) do segmento ST. Com o intuito de constatar algum dano nas células do miocárdio em condições de má perfusão, utilizaram-se 38 cães, dos quais 20 com traçados eletrocardiográficos normais e 18 com desníveis (infra e supra) do segmento ST, na derivação DII, velocidade de 50 mm/s e sensibilidade N. Nos animais normais (grupo 1), a dosagem sérica da enzima creatinafosfoquinase isoenzima MB (CK-MB) e da troponina I (cTnI) destinou-se à obtenção dos valores de referência (em ng/mL). Estes valores de referência foram confrontados com os obtidos de cães portadores de desnível (grupo 2), permitindo confirmar ou não a injúria miocárdica. Em relação à CK-MB, os cães do grupo 1 apresentaram média de 0,54 ng/mL e desvio-padrão de 0,89 ng/mL e os do grupo 2 apresentaram média de 0,44 ng/mL e desvio-padrão de 1,106 ng/mL. A média e o desvio-padrão foram, respectivamente, de 0,16 ng/mL e 0,110 ng/mL e de 0,20 ng/mL e 0,111 ng/mL, nos grupos 1 e 2. Houve 18 valores nulos de CK-MB, igualmente distribuídos entre ambos os grupos. O grupo 1 apresentou três valores nulos para cTnI. Houve diferença marcante em relação à idade, sendo o grupo 1 constituído por animais, preponderantemente, abaixo de 7 anos; o contrário ocorreu no grupo 2. São significativas, ao nível de significância de 5%, as associações da variável CK-MB com as variáveis idade, massa e CK-T (creatinafosfoquinase total) no grupo 1, e com a variável CK-T no grupo 2. A variável cTnI não apresentou evidências de associação, ao nível de significância de 5% , com as variáveis idade, massa, CK-T e nível sérico de potássio, para cada um dos níveis da variável grupo. Tanto para a variável CK-MB quanto para a cTnI, não houve diferenças significativas, ao nível de 5%, entre os grupos 1 e 2. Conclui-se que é possível a utilização do \"kit\" de ensaio imunométrico quimioluminescente humano para a espécie canina e que a hipóxia/isquemia, revelada pelo desnível do segmento ST, não acarreta dano miocárdico, ou que este é mínimo. / Although very often in men, hypoxic and ischemic heart diseases are poorly documented in dogs. There are few reports of acute myocardial infarction (AMI) in this species. However, some electrocardiographic findings may suggest myocardium hypoxia/ischemia, like ST segment elevation or depression. In order to investigate myocardial cells injury in poor perfusion conditions, 38 dogs, being 20 with normal electrocardiogram and 18 with ST segment elevation or depression in lead II, at a paper speed of 50 mm/sec and N sensibility (1 mV = 1cm), were included. Serum measurement of creatinephosphokinase isoenzyme MB (CK-MB) enzym and troponin I (cTnI) in normal dogs (group 1) determined reference values (in ng/ml). These values were compared to those obtained in dogs with deviation (group 2), which allowed confirmation or not of myocardial injury. CK-MB mean values obtained from dogs in groups 1 and 2 was 0,54 ng/mL (SD±0,54 ng/mL) and 0,44 ng/mL (SD±1,106), respectively. Mean cTnI values in groups 1 and 2 was 0,16 ng/mL (SD±0,110 ng/mL) and 0,20 ng/mL (SD±0,111 ng/mL) respectively. Three cTnI null values were found in group 1. There was a marked difference concerning to age, being group 1 composed, mainly, by animals ageing under 7 years, on the contrary of group 2. At a significance level of 5%, was significant the relation of CK-MB with age, mass and total creatinephosphokinase (CK-T) in group 1 and with CK-T in group 2. There is no relation, at a significance level of 5%, of cTnI with age, mass, CK-T or serum potassium concentration, for each level of group variable. Both CK-MB and cTnI variables showed no difference, at 5% level, between groups 1 and 2. In conclusion, it is possible to use the human chemiluminescent immunometric assay kit in canine species and that hypoxia/ischemia revealed by ST segment deviation does not mean significant myocardium injury.

A investigação da Terra através da gravimetria implica um grande número de informações sobre o seu interior em diferentes escalas de observação. O presente estudo considerou pesquisas anteriormente realizadas na área da Zona de Fratura São Paulo (ZFSP) e Arquipélago São Pedro e São Paulo (ASPSP), no Oceano Atlântico Equatorial, cujos dados geoquímicos e petrológicos apontam a presença de uma anomalia térmica. Nesta área alguns levantamentos geofísicos já foram realizados, mas nada que contribuísse de forma significativa através de dados gravimétricos. O objetivo principal deste trabalho é a caracterização gravimétrica da Zona de Fratura São Paulo através de dados de gravidade, anomalia ar livre, anomalia bouguer, tensor gradiente da gravidade e altura geoidal residual. Como objetivo secundário, procurou-se a expressão desta anomalia térmica no campo geopotencial. Entretanto, os resultados obtidos indicam que o efeito da batimetria sobre este dados deve ser levado em consideração. Uma vez que área de estudo está localizada na porção equatorial da dorsal mesoatlântica e o processo de compensação isostática nesta área está influenciando os valores da gravidade no local. Sendo, portanto, necessária a confluência de outros métodos geofísicos para detectar a expressão desta anomalia térmica. / The investigation of the Earth by gravity implies a lot of information about the interior at different scales of observation. This study considered research previously conducted in the area of St. Paul Fracture Zone (ZFSP) Archipelago and St Peter and St Paul (ASPSP), the Equatorial Atlantic Ocean, whose petrological and geochemical data indicate the presence of a thermal anomaly. In this area some geophysical surveys have been conducted, but nothing that would contribute significantly by gravity data. The main objective of this work is the characterization of gravimetric St. Paul Fracture Zone by gravity data, free air anomaly, Bouguer anomaly, the gravity gradient tensor and residual geoid height. As a secondary objective, have sought the expression of this thermal anomaly in the field geopotential. However, the results indicate that the effect of bathymetry on this data should be taken into consideration. Since the study area is located in the equatorial portion of the mid-ridge atlantic and the process of isostatic compensation in this area is influencing the gravity values at the site. Therefore required the confluence of other geophysical methods to detect the expression of this thermal anomaly.

The St Francis Bay beach has experienced chronic erosion over the past three decades. This erosion can largely be attributed to the stabilisation of a large coastal dunefield which contributed +/- 80 percent of the sand supply to St Francis Bay. Stabilisation began in 1975 initially using plant cuttings and followed by the development of the Santareme holiday suburb resulting in complete stabilisation by 1985. Effects were felt from the late 1970‟s and since then the beach has retreated at between 0.5 - 3 m.yr-1. Erosion has encroached on beachfront properties since the early 1990‟s, leading to the placement of 3-4 m high unsightly rock revetments along much of the beach. Where properly maintained these structures have proved successful in protecting the properties behind, however exacerbated erosion of areas in front and adjacent to these structures is evident. Currently no dry beach is present at high tide for most of the year, leading to a significant reduction in beach amenity value. Several technical studies to investigate remediation of this beach erosion problem have been conducted since the early 1990‟s. This study includes investigations into the processes and dynamics of the existing environment and evaluation of the effectiveness and impacts of several elements of a hybrid approach to coastal protection and amenity enhancement for St Francis Bay beach. This proposal incorporated: Multi-Purpose Reefs (MPR‟s) offshore, for coastal protection and amenity enhancement in terms of surfing; beach nourishment with sand from the Kromme Estuary and dune rehabilitation with appropriate native sand binding species. Extensive fieldwork and data collection were conducted, this included: a series of bathymetric surveys; diving surveys and a helicopter flight; sediment sampling; beach profiling and deployment of a wave/current meter. Analysis of these data provided a greater understanding of the existing environment and dynamics of St Francis Bay and provided reliable inputs for numerical modelling. Numerical and physical modelling was conducted to assess the existing processes and conduct MPR design testing. In addition calibrated hydrodynamic modelling of the Kromme Estuary was conducted in order to assess the impacts of sand extraction from the large sand banks within the mouth of the Kromme Estuary for use as beach nourishment. Comparison of bathymetric survey data collected by the author in 2005/06 with survey data collected by the South African Navy Hydrographic Office (SANHO) in 1952 suggest a major loss of sand from the bay, with a volume difference of some 8.8 X 106 m3 calculated. Greater losses were measured between 10-15 m water depths, with shallow areas of +/- 5 m water depth, remaining more stable. This can be attributed to the presence of shallow reef and rocky substrate through much of the bay at this depth range. Monthly RTK GPS survey data from September 2006 to September 2007 indicates a total loss of 40 000 m3 over this period with the greatest losses measured along the northern part of the beach. The greatest losses were measured after large long period waves from a southerly to south-easterly direction occurred in conjunction with equinox tides in mid March 2007. Sediment sampling at over 100 locations within the bay indicated a high percentage of reef (26 percent) and fairly consistent grain size in the fine to medium size class throughout much of the beach, bay and large sand bank within the estuary. While the majority of the South African Coast is exposed to the predominant south westerly winds and waves, St Francis Bay‟s orientation means that waves from a south easterly to easterly direction dominate. The results of the detailed numerical modelling of the hydrodynamics agree with previous calculations and modelling results which concluded that strong unidirectional longshore currents occur along the headland due to the oblique angle of wave incidence and the close to parallel angle of wave incidence along the beach leads to weak longshore currents of variable direction. Erosion along St Francis Bay beach is a result of cross-shore erosion due to large waves from a southerly to easterly direction. Detached breakwaters are the most effective form of coastal protection in these environments and MPR‟s offer additional benefits over traditional breakwater structures. Results of empirical calculations and numerical modelling indicate that the MPR‟s will provide effective coastal protection through the processes of wave dissipation, wave rotation, salient formation and alteration of nearshore circulation. Physical modelling results allowed the MPR design to be assessed and refined in terms of surfing amenity enhancement and construction constraints. In addition numerical modelling results indicate that impacts due to the extraction of up to 600 000 m3 of sand from the lower Kromme Estuary result in highly localised velocity reduction, mainly limited to the extraction areas. The calculated rate of sediment influx into the lower Kromme Estuary indicates that limited extraction, in the order of 20 000 – 40 000 m3 per year, should be sustainable in the long term. Sedimentation of the lower estuary over recent years has had negative recreational and ecological impacts, through reduced navigability and water exchange respectively. Therefore both the estuary and beach systems prove to benefit from this approach. Although not investigated in detail as part of this study, evidence from numerous projects worldwide indicates that foredunes help to trap wind-blown sand on the beach and form a buffer to storm erosion, therefore dune rehabilitation with native sand-binding plant species was recommended as the third element of the proposed remediation of St Francis Bay beach.

Picture a historical library and a historical art museum coming together to challenge the interaction between each other to help experience, explore, and discover the past within the present. While it sounds like a good idea, it is rare to see a library and museum under one roof. With the increasing population of tourists looking to visit places and buildings that reconnect with history, there is a higher demand for places to be able to 're-live the past' through art and literature. People enjoy visiting places where history was made and where it becomes part of a city's identity. With modern developments taking over, historical buildings are beginning to disappear. Designing a library and museum partnership is a solution to creating two institutions under one roof while preserving the space usually needed for both institutions if built separately. In order to challenge the idea of a hybrid building within a historical city, there needs to be an element of culture and historical remembrance that creates a shield against that city's potential loss of identity. Memory has become a key element in our true identity, becoming a form of support against erasure. It is that sense of culture and historical remembrance that will create recognition of things past. In order to address Florida's historical culture, the proposed site will be located in St. John's County, which includes America's oldest city St. Augustine. There are many different historical periods in St. Augustine that create its current cultural atmosphere. It is important to choose an environment where historical events took place because it allows the memory process of a place to create past experiences to be shared with new experiences. Through a methodology of the historical culture and conditions of the site, this thesis project will honor St. Augustine's culture by integrating the past with the present and creating a modern hybrid institution for the city. Furthermore, integrating the past with the present will allow users to enjoy St. Augustine as it used to be and as it currently is today.
