Die koloniale manifestasie van die Neo-Gotiese kerkboustyl op die Tuinroete van Suid-Afrika

De Swardt, Ignatius P. 03 1900 (has links)
Thesis (MA)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: During the 12th century the Ab Suger, a church leader from near Paris in France, initiated a new approach to church architecture, the Gothic style. He diverted from the existing traditions and utilized pointed arches as one of the basic components of the new style. Pointed arches, unlike normal arches, distribute load-carrying weight not only downwards, as normal arches do, but also sideways. Strategically placed flying buttresses can help neutralize the thrust to the sides and reduce the weight on walls. Walls no longer had to be massive and it became possible to utilize big parts of the walls for windows, which were filled with brightly coloured glass. The style deliberately made use of height and enclosed spaces as a design element, to an extent unknown until that time. For some four centuries cathedrals in this style were built all over Europe, before the style was replaced with the coming of the Renaissance. The 19th century saw the coming of a style of Gothic Revival. New building materials had become available and there were fundamental differences between the original Gothic style and the Neo-Gothic (or Gothic Revival) style. In some instances elements of the original style lost their functions and were applied in a purely decorative function in the Gothic Revival style. With the colonization of Africa, the Neo-Gothic style came to South Africa. It took root locally and became part of South African church architecture. Local conditions required that some adaptations be made and several varieties of the Neo-Gothic style became part of the South African architectural landscape. Many church buildings were constructed in South Africa in this style during the last century and a half. The ones older than sixty years enjoy some measure of protection under current legislation relating to heritage conservation. It became evident that within the variety of Neo-Gothic idioms a number of churches have become so simplified that only some characteristics of the style have remained. Throughout the study it was indicated how the significance of a building and its architectural style also impact on the non-material culture of a community. / AFRIKAANSE OPSOMMING: Gedurende die 12de eeu het ab Suger, ‘n kerkleier van naby Parys in Frankryk, met ‘n nuwe benadering tot kerkargitektuur na vore gekom wat later as die Gotiese styl sou bekend staan. Hy het afgewyk van bestaande tradisies en gebruike in verband met kerkargitektuur. Deur die aanwending van spitsboë is die afwaartse druk van ‘n kerk se dak gedeeltelik na buite verplaas, in plek van alles na onder. Strategies geplaasde boogstutte het die sywaartse druk geneutraliseer. Hierdie boumetode is saam met die gebruik van geribde gewelwe gebruik om die druk in so ‘n mate van symure af te haal dat die mure nie meer dik en sterk moes wees nie en dit moontlik was om groot dele van die mure met vensters van gekleurde glas te vul. Die nuwe styl het ingeslote ruimtes en hoë gewelwe gehad soos die Middeleeuse mens nog nie vantevore geken het nie. Vir sowat vier eeue lank het katedrale in dié styl oral oor Europa opgeskiet, totdat dit met die koms van die Renaissance deur ander style vervang is. In die 19de eeu het daar ‘n herlewing in die Gotiese styl gekom. Beter boumateriale was beskikbaar en die Gotiese Herlewingstyl het in sommige opsigte groot verskille met die oorspronklike getoon. Van die Gotiese boustyl se komponente is aangepas om totaal ander funksies te vervul. Verskeie aspekte van die Gotiese styl is slegs behou as versiering. Met die kolonisasie van Afrika het die Gotiese Herlewingstyl na Suid-Afrika gekom. Die styl het posgevat en versprei in Suid-Afrika maar plaaslike omstandighede het aanpassings daarvan genoodsaak en etlike variasies op die Neo-Gotiese tema het na vore gekom. ‘n Groot aantal kerke is in die afgelope anderhalf eeu in Suid-Afrika in hierdie styl gebou. Sommiges daarvan geniet ‘n mate van beskerming ingevolge Suid-Afrika se bewaringswetgewing. Hierdie studie fokus op kerkgeboue met Neo-Gotiese stylkenmerke in ‘n bepaalde geografiese gebied in Suid-Afrika. Daar is bevind dat van die variasies op die Neo-Gotiese styl so vereenvoudig het, dat daar slegs enkele stylkenmerke by hulle oorgebly het. Deurgaans is aangedui op watter wyse die betekenis van die kerkgebou en die styl daarvan ook die nie-tasbare kultuur van ‘n gemeenskap geraak het.

Návrh a ověření turistického průvodce Telčska\\ / Suggestion and testing of turist guide of Telč region\\

MALEČKOVÁ, Iveta January 2007 (has links)
The aim of my dissertation work is to propose and validate the system of touristic routes around Telč in a form available especially for children at primary school. It should be available also for other students and for public. Tourism is explained in general terms and is linked to specific curriculum of primary school. Telč and its surroundings is suitable particularly for hiking, but there are also possibilities for cycling. That is the reason why in my thesis I mentioned also cycling tourism.I am talking about Telč and its surroundings as a whole, however, there is a brief characteristics of some destinations in this area.Touristic routes are described in a special way as you could become acquainted with them before the trip: length and difficulty of the route, time demandingness, start and finish points, interesting things we can see. There is a map describing the route. Each route is named, mainly because of lucidity to motivate the people.

'n Ontleding van landboutourisme in die Tuinroete-gebied van Suid-Afrika

De Jager, Jacobus Lodevicus January 2003 (has links)
The aim of this study was to create a profile of the agricultural tourism industry in the Garden Route area of South Africa, and to determine what general influence agricultural tourism has on the macro environment (rural area) with regard to socio- economic development, as ell as on the micro environment (farm) with regard to the generating of additional income. This study only includes agricultural operations (farms) in the Garden Route area that practice tourism activities. Out of 54 potential agricultural units that were identified, 46 were willing to participate in the study. Information from only 40 of the abovementioned units was finally included in this study. Six agricultural units could not supply sufficient information during the surveys. Data were gathered by means of a scientifically compiled questionnaire. All the individuals involved in this study completed this questionnaire by means of a personal interview. The aspects investigated in order to compile a profile were the characteristics of the suppliers, activities and the extent of the agricultural tourism industry. In order to determine the contribution of agricultural tourism on micro- and macro levels, aspects such as the contribution to farming turnover were investigated as well as the socioeconomic contribution in view of the infrastructure development, job creation, education and housing. The results of this study indicate that 78% of respondents are aged 40 years and older, are mainly male, and, in most of the cases, married (95%). Agricultural tourism enterprises in the Garden Route area are, in most cases (60%), managed by the farmers’ wives. The business type whereby respondents’ agricultural tourism enterprises are conducted, is as follows: in 72.5% of the cases a sole ownership, 17.5% a private company, 5% a partnership, 2.5% a closed corporation and the other remaining 2.5% is managed as a trust. The majority (65%) of persons involved in the management of the agricultural tourism enterprise has received some form of tertiary education. A degree of statistical significance (p = 0.0728) exists between the education level of the type of person/persons that manages the tourist branches and the type of activity category that is offered. In 65% of the cases the farms that offered agricultural tourism, were smaller than 500 hectare. A negative correlation (r² = -0.31700; p<0.0001) was found between farm size and the total farming turnover per year. This trend is even more distinctive (r² = -0.47156; p<0.0001) for farms smaller than 1 000 ha. A statistically meaningful (p = 0.0115) relationship exists between farm size and the number of activities that were offered. This occured in cases where farms were smaller than 1 000 ha. In 25% of the cases only one agricultural tourism activity was offered, 12.5% of these farms were 100 ha or smaller. The maximum number of activities that were offered was 11 and it was found in 3.13% of the cases. A highly statistically meaningful (p = <0.0001) connection exists between the percentage tourism turnover per year and the different types of activity categories that were offered. In 35.75% of the cases these activity categories earned between 1 and 10% of the yearly tourism turnover. A highly statistically meaningful (p = 0.0036) connection also exists between the degree of popularity and the type of activity category that was offered. In 53.07% of the cases the most popular activities were those that are nature-based, followed by accommodation-based activities (23.46%). In 82.5% of the cases additional income was the main reason for offering agricultural tourism. Other distinctive reasons were the love for people (50%) and the desire to share the farm life and beauty with others (25%). The tourism activities that were offered on the farms were respectively, guest houses (62.5%) followed by hiking trails (57.5%) and swimming opportunities (32.5%). Wildlife viewing was the activity that has been offered for the longest period of time, some 11,5 years. The general location of the agricultural tourism operations were 21.9 km from towns and 9.65 km from main routes. Word-of-mouth was the most successful marketing method, followed by the use of own brochures (90%) and local tourism bureau brochures (87.5%). A degree of statistical significance (p = 0.0902) exists between the number of marketing methods and the average percentage of the tourism branch as a total part of the total farming turnover per year. A positive correlation (r² = 0.29118; p<0.0001) exists between the number of marketing methods and the total farming turnover per year. Visitors to the agriculture tourism operations were in 55% of the cases mainly domestic tourists, followed by 25% that includes both domestic and foreign tourists, and a further 20% that mainly includes foreign tourists. The majority (67.5%) of operations indicated that agricultural tourism formed less than 30% (between 2% and 30%) of their annual agricultural turnover, 5% between 30% - 50%, 25% between 80% - 100% of their turnover, while 2.5% generated no income from agricultural tourism. A highly statistically meaningful (p = 0.0010) relationship exists between the percentages that the tourism branch contributes as a total of the farming turnover per year and the number of years that the respondents hade been involved in the offering of agricultural tourism. A positive correlation (r² = 0.30005; p<0.0001) exists between the number of years involved with the offering of agricultural tourism and the average percentage of the total farming turnover per year. New infrastructure was created by 40% of the providers, a further 12.5% partially created new infrastructure, while 47.5% made use of infrastructure that was already in place. Thus far job opportunities have been created for 58 people of whom 13.79% are male and 86.21% are female. A statistically meaningful (p = 0.0406) relationship exists between the number of workers that had to be appointed additionally and the number of activities that were offered. In 17.5% of the cases it was only needed to appoint one worker, followed by 2.5% that appointed three workers each, 5% that had to appoint four workers each and a further 2.5% that had to appoint seven workers each. There are 27.5% of agricultural tourism providers that had to appoint additional workers, 20% provided education to those workers and 36.36% of the above-mentioned provided housing to those workers and their dependants. A statistically meaningful (p = 0.0209) relationship exists between education provided to workers that had to be appointed additionally and the type of activity combination that was presented. A degree of statistical significance (p = 0.0691) exists between housing provided to additional workers and the number of activities that were presented. A statistically meaningful (p = 0.0455) relationship further exists between housing provided to workers that had to be appointed additionally and the type of activity combination that was presented. From the results of this study it appeared that the development of agricultural tourism in the Garden Route area has a positive impact on the micro- and macro environments of the rural areas. This impact can make a direct or indirect contribution to the socio-economic development of this region and it can induce the generation of additional income, infrastructure development, job creation, education and housing. This study suggests that there is significant potential for the further development and exploitation of agricultural tourism.

Are Dominant Routes the Least Stressful Routes in a Bike Share System? An Investigation of Hamilton Bike Share using Weighted Level of Traffic Stress

Ubhi, Rajveer January 2021 (has links)
Level of Traffic Stress (LTS) is a four-level system that classifies the stress experienced by cyclists on road segments and at intersections. While LTS has been used in past studies to assess cycling connectivity, accessibility, and safety, very little is known concerning its influence on cycling preferences. This study investigates this topic using a dataset containing 323,163 unique GPS trajectories of Hamilton Bike Share (HBS) users collected over a 12-month period (January 1st to December 31st, 2019). A GIS-based map-matching algorithm is used to generate users’ routes from these trajectories along with attributes such as route length, number of intersections, and number of turns. Unique routes and their use frequencies are then extracted from all routes. The most popular routes between bike share hub (station) pairs are then identified as dominant routes while shortest distance routes are derived by minimizing distance traveled. Weighted level of traffic stress (WLTS), a novel measure of impedance (travel cost) developed for this study, is used to derive the least stressful routes between hub pairs. The three types of routes are compared statistically. The comparison finds that HBS users tend to choose longer routes with bicycle infrastructure in an effort to reduce their traffic stress. However, they do not choose to minimize traffic stress in its entirety by choosing the lowest WLTS routes. In other words, dominant routes are not the least stressful routes in a bike share system. Likewise, minimizing distance is not the sole consideration of HBS users. The findings suggest that other factors also influence route choice. This study not only enhances our understanding of cyclist route preferences with respect to LTS, it also presents a novel measure of impedance – WLTS – that could be used when planning new cycling infrastructure or as an alternative means to route cyclists between origins and destinations. / Thesis / Master of Science (MSc)

UNDERSTANDING BIKE SHARE CYCLIST ROUTE CHOICE BEHAVIOR

Lu, Wei 11 1900 (has links)
This thesis examines the existence of a dominant route between a hub pair and factors that influence bike share cyclists route choices. This research collects 132,396 hub to-hub global positioning system (GPS) trajectories over a 12-month period between April 1, 2015 and March 31, 2016 from 750 bicycles provided by a bike share program (BSP) called SoBi (Social Bicycles) Hamilton. Then, a GIS-based map-matching toolkit is used to convert GPS points to map-matched trips and generate a series of route attributes. In order to create choice sets, unique routes between the same hub pair are extracted from all corresponding repeated trips using a link signature tool. The results from t statistics and Path-size logit models indicate that bike share cyclists are willing to detour for some positive features, such as bicycle facilities and low traffic volumes, but they also try to avoid too circuitous routes, turns, and steep slopes over 4% though detouring may come with a slight increase in turns. This research not only helps us understand BSP cyclist route preferences but also presents a GIS-based approach to determine potential road segments for additional bike facilities on the basis of such preferences. / Thesis / Master of Science (MSc)

Développement de lois de comportement générales pour des sols soumis à des chargements de véhicules hors-routes

Cruz Sánchez, Jesús David 10 February 2024 (has links)
Il existe actuellement plusieurs modèles qui permettent de prédire le comportement et les performances d'un véhicule. Le succès ou non de ces modèles donnera le consentement pour le développement et l'intégration d'équipements hors-route utilisés dans la construction, l'agriculture et les véhicules de loisirs. Cependant, la représentation du sol dans ces modèles montre des limitations concernant au comportement de l'interface pneu-sol. Premièrement, la teneur en eau et le compactage sont des facteurs qui influencent le comportement rhéologique du sol et cette résistance à se déformer est à la fois influencée par les différentes formes d'application de chargement le long d'une trajectoire du pneu sur une particule de sol. Par conséquent, ce projet cherche à s'appuyer sur les fondements de la géotechnique routière pour la prédiction des performances des matériaux soumis à des charges cycliques. Des fondamentaux qui permettront de développer des outils pour comprendre, d'un autre point de vue, l'interaction entre les sols et les pneus provenant des véhicules hors-route. / There are currently several models that can be used to predict a vehicle's behaviour and performance. The success or failure of these models will give consent for the development and integration of off-road equipment used in construction, agriculture, and recreational vehicles. However, the soil representation in these models shows limitations in the behaviour of the tyre-ground interface. Firstly, moisture content and compaction are factors that influence the rheological behaviour of the soil and this resistance to deformation is both influenced by different forms of loading application along a tyre's trajectory on a soil particle. Therefore, this project seeks to build on the foundation of the geotechnics of roads for the prediction of the performance of materials subjected to cyclic loading. These fundamentals will enable the development of tools to understand, from another point of view, the nteraction between soils and tires from off-road vehicles.
