This study aims to explore effectiveness within intermodal transportation of semi-trailers based on the variables cost and time. Intermodal transport can be explained as a transportation of a carrier, from the origin to the final destination, using two or more modes of transport (Crainic & Kim, 2007 p.467). This study focuses on the two modes of transport rail and road. The rail transportation has big advantages towards other modes of transport since it has less impact on the environment, given that the energy is produced in Sweden (Trafikverket 2017) but there are more benefits to be utilized. The rail transportation is generally more profitable on distances greater than 500 km, thus it can transport high volumes of goods over long distances for a low cost. The fixed costs that´s added in the terminals and the rail transports low degree of flexibility compared to the road transport is the primary reasons why rail transportation isn´t profitable on shorter distances. This study has made a market research to see where the final destinations for the imported semi-trailers are located in Sweden and Norway. This, to see where there are potential to develop and create new rail shuttles from Port of Gothenburg to dry ports across the Swedish and Norwegian inland for transportation of semi-trailers. Interviews have been conducted with carriers to create a more correct view of the current situation. Study results show that the greatest volumes of the transported semi-trailers ends up in the areas around Helsingborg and Stockholm, with the region around Gothenburg excluded. Dry ports positioned in this area show the best potential for development of new rail shuttles. The results from conducted interviews with carriers express that time is the most important aspect for their operation and their clients, that is also the reason why they don´t use the railway for transportation of semi-trailers. Carriers also consider the trains to be unreliable and the railway operation in Port of Gothenburg has so far not been operating well enough for them. The result show that 38 percent of the imported semi-trailers have their final destination in the area around Gothenburg and naturally it´s not possible for the railway to compete with the road transport at such a short distance. In order for the railway to compete with the road transport, rail shuttles to regions with high flows of semi-trailers must be developed to not loose in time and flexibility. Thus, the railway transportation has other opportunities than just transportation. In dry ports there are opportunities for storage of goods, which is generally cheaper than in the port and simultaneously create time gains in the final transportation, thus the goods are closer to the customer. Port of Gothenburg can compete with other ports, which are geographically closer to a certain customer, through more rail shuttles with more frequent departures and then take more market shares within Nordic transportation. / Studien syftar till att undersöka transporteffektiviteten för intermodala transporter av semitrailrar med utgångspunkt från variablerna kostnad och tid. Intermodala transporter kan förklaras som en transport av en lastbärare från dess ursprung till dess slutdestination med hjälp av två eller flera olika transportsätt (Crainic & Kim, 2007 s.467) och denna studie fokuserar på de två transportsätten järnväg och väg. Just järnvägstransporten har en stor fördel gentemot andra transportsätt då det är ett mer miljövänligt alternativ, förutsatt att det är eldrivna tåg samt att elen är producerad i Sverige (Trafikverket 2017) men det finns även fler fördelar som kan utnyttjas. Järnvägstransporten är generellt lönsammare på avstånd längre än 500 km, då det kan transportera stora volymer över långa avstånd till en låg kostnad. Varför det inte är lönsamt på kortare sträckor beror framför allt på de fasta avgifter som tillkommer vid terminalerna och järnvägens relativt låga flexibilitet gentemot vägtransporten. Studien har gjort en marknadsundersökning för att se var de importerade semitrailrarna har sin slutdestination inom Sverige och Norge. Det för att se var det finns potential för att utveckla och skapa nya järnvägspendlar från Göteborgs Hamn till torrhamnar för transport av semitrailrar via järnväg. Intervjuer har utförts med speditörer i anslutning till hamnen för att skapa en så bra bild som möjligt av nuläget. Resultatet visar att de största volymerna i flödet av semitrailrar går till Helsingborg och Stockholm med omnejd, med Göteborg exkluderat. Det är de två områdena som visar potential för att eventuellt skapa järnvägspendlar till torrhamnar. Vid intervjuerna som utförts uttrycker speditörerna att tid är den viktigaste aspekten för deras verksamhet och kunder. Det är även anledningen till att de inte använder sig av järnvägstransport för semitrailrar, då tågen är för opålitliga och verksamheten för järnvägstransport kring Göteborgs Hamn inte har fungerat för dem hitintills. Resultatet visar även att drygt 38 procent av de importerade semitrailrarna har sin slutdestination i Göteborgsområdet och där kan naturligtvis inte järnvägstransporten konkurrera med vägtransporten på grund av det korta avståndet. För att järnvägstransporten ska kunna konkurrera med vägtransporten måste det skapas pendlar till de regionerna med större flöden för att inte förlora tid och flexibilitet gentemot vägtransporten. Dock så ger järnvägstransporten andra möjligheter än bara transport av gods. I torrhamnarna finns möjligheter för lagring av gods, som generellt är billigare än lagring i hamnen och ger samtidigt tidsvinster när den slutliga transporten till kund ska utföras, då godset är närmare kunden. Göteborgs Hamn kan konkurrera med andra hamnar som geografisk ligger närmare en viss kund, genom att fler järnvägspendlar med frekventare avgångar kan skapas och på så sätt ta marknadsandelar inom nordisk transport.

本研究目的是從電影敘事和互文理論的角度去了解台灣電影預告片的風格模式為何？以好萊塢電影預告片為參照點，了解台灣電影預告片操作什麼元素來吸引觀眾？與好萊塢電影預告片有何差異？更重要的是透過研究者對台灣電影預告片剪接師的訪談資料，了解台灣電影預告片的產製環境和流程，完整了解台灣電影預告的生成，並試圖發現可能有的台灣電影預告片模式。 　　本研究以2000年至2010年國片票房前十名為研究樣本，首先依據製作規模與資金來源等將十部影片分成三類，並依據好萊塢電影預告片模式特徵，將文本分成敘事、視覺文本、聽覺文本、明星等四元素，分析三類別的預告特徵。 　　研究結果發現，不同的製作規模會影響台灣電影預告片風格，有國際資金與國際團隊規模製作的準好萊塢電影預告片，模式特徵與好萊塢電影預告片相似，重場面、類型、明星等，強而有力的視覺呈現是其重點與賣點；有亞洲資金與兩岸三地團隊製作的類好萊塢電影預告片，預告片的剪接技巧特徵仿效好萊塢預告片的同時，將場面和明星的不足，轉移到以衝突和人物為中心，故事輪廓漸浮現。 　　只有本土資金和傳統台灣電影手工業製作條件的演化中的台式電影預告片，呈現出明顯不同的電影預告片特色，此類別以故事來包裝，從本土出發，放入象徵台灣的符號、語言，並且嘗試不同技法來填補場面、類型、明星的不足，像是電影主題曲、大量演員、字卡、各大影展獎項等，利用其他元素來強化影片豐富度，敘事與聽覺變成揮灑創意的文本，補足視覺文本的不足。 　　本研究預期藉由台灣電影預告片的文本分析和產製端的訪問，形塑出台灣電影預告片的風格，並且進一步找到適合台灣電影預告片發展模式，增加台灣電影預告片整體效益。 / The purpose of the study is to investigate styles of Taiwanese movie trailers from the film narrative and intertextual perspectives. First of all, we need to determine elements used in Taiwanese movie trailers and what differences these elements have in comparison with those in Hollywood movie trailers. Moreover, we have to understand conditions and processes of producing those trailers by interviewing trailer editors in Taiwan. By doing so, we will be able to categorize different types of Taiwanese movie trailers. Based on four major elements of Hollywood movie trailers, namely, narration, visual, audio and stars, the study finds that there are three types of trailers in Taiwan cinema: Quasi-Hollywood trailers, Hollywood-like trailers, and Taiwan local movie trailers. It is hoped that the study findings might help Taiwan cinema to maximize effects of its movie trailers.

In this way of research, the present work aimed to develop a machine composed by gin, press baler and tow, which concerns the familiar cotton growers. The gin machine consists of a manual feeder cleaner, saws cylinder, brushes cylinder, condenser and coil. The baler press consists of veneer, hydraulic cylinders, hydraulic pump, control valve actuation, filtering devices for hydraulic oil and manometer: and the tow composed by chassis of U corner, 13" wheels, axis cusp, two bundles with five coil springs, iron ballast and self brake. The hole set has been evaluated and validated in field and by cotton growers of family farming associations considering the main characteristics of: fiber technology and physical and physiological of seed. For the ginning was studied the rotations, cultivars, saws types and cleaning processes; for the baler press was evaluated the number of presses and the capacity for forming a bale; while to the tow was considerate the safety factor of the axis and chassis scaling. Based on the results, the set of gin, baler and tow fully complied with the efficiency required by textile industry. The proposed goals proved that the technological characteristics of the cotton fiber benefited remained within the standards established by classification norm for the textile industry to not damage the quality of seeds. During the evaluation and validation made by farmers, composed by 15 items, considering efficiency of gin and the bale weight, this machine received the concept "very good" of the family cotton growers.

Articulated Heavy Goods Vehicles (HGVs) are more efficient than conventional rigid lorries, but exhibit reduced low-speed manoeuvrability and high-speed stability. Technologies such as autonomous reversing and path-following trailer steering can mitigate this, but practical limitations of the available sensing technologies restrict their commercialisation potential. This dissertation describes the development of practical vision-based articulation angle and trailer off-tracking sensing for HGVs. Chapter 1 provides a background and literature review, covering important vehicle technologies, existing commercial and experimental sensors for articulation angle and off-tracking measurement, and relevant vision-based technologies. This is followed by an introduction to pertinent computer vision theory and terminology in Chapter 2. Chapter 3 describes the development and simulation-based assessment of an articulation angle sensing concept. It utilises a rear-facing camera mounted behind the truck or tractor, and one of two proposed image processing methods: template-matching and Parallel Tracking and Mapping (PTAM). The PTAM-based method was shown to be the more accurate and versatile method in full-scale vehicle tests. RMS measurement errors of 0.4-1.6° were observed in tests on a tractor semi-trailer (Chapter 4), and 0.8-2.4° in tests on a Nordic combination with two articulation points (Chapter 5). The system requires no truck-trailer communication links or artificial markers, and is compatible with multiple trailer shapes, but was found to have increasing errors at higher articulation angles. Chapter 6 describes the development and simulation-based assessment of a trailer off-tracking sensing concept, which utilises a trailer-mounted stereo camera pair and visual odometry. The concept was evaluated in full-scale tests on a tractor semi-trailer combination in which camera location and stereo baseline were varied, presented in Chapter 7. RMS measurement errors of 0.11-0.13 m were obtained in some tests, but a sensitivity to camera alignment was discovered in others which negatively affected results. A very stiff stereo camera mount with a sub-0.5 m baseline is suggested for future experiments. A summary of the main conclusions, a review of the objectives, and recommendations for future work are given in Chapter 8. Recommendations include further refinement of both sensors, an investigation into lighting sensitivity, and alternative applications of the sensors.

The trailer will, therefore, be analyzed not only as a tool of movie marketing, but mostly as a 'shortmovie' which has a kind of parallel narrative and assist in the feature film, with a beginning, middle and end, trying to understand how that is constituted and how it still speaks to the disclosure´s posters and the opening credits of the film. Both 'core' sequence storyboard´s (trailer and movie) will also be used in this reading that seeks to comprehend the process of signification in the orbit of Psycho. / O objetivo desta dissertação é estudar a narrativa do trailer de um dos mais influentes filmes da história do cinema: Psicose (1960), de Alfred Hitchcock. O trailer será, portanto, analisado não apenas como uma ferramenta de marketing cinematográfico, mas principalmente como um 'curta' que conta com uma espécie de narrativa paralela e auxiliar à do longa-metragem, com início, meio e fim, tentando compreender como aquela se constitui e de que forma dialoga ainda com os cartazes de divulgação e com os créditos iniciais do filme. O storyboard da sequência 'central' de ambos (trailer e filme) também será utilizado nesta leitura que visa compreender o processo de significação na órbita de Psicose.

The controlling of mobile robots has been and still is in the focus of researchers. Fuzzy rule-based controllers are extensively used to control robots. Path planners were created using different search methods finding the shortest  trajectory between two points and thereby avoiding recorded obstacles. The low degree of automation in hospitals promises huge potential for increasing logistical effects by the use of mobile robots. Especially the automated transport of a hospital bed, which manually requires two persons, would release time from transportation activities. The usage of a mobile robot joined to a hospital bed makes controlling considerably harder. This document describes a project accomplished by me in cooperation with RobCab AB. During the project, a path planner was created and controlling strategies to move a mobile robot joined to a hospital bed between two locations was implemented. The controlling strategies are not only based on sensor readings from a laser mounted on the mobile robot and a list of way points provided by a path planner but incorporates also the position of the bed in the environment. The robot adapts its behavior to ensure a safe movement considering the position of the bed which is not only determined by the kinematics of the robot-bed model but also by an external force in the form of a person following the transport (human intelligence). Development was done on the Stage simulator and is intended to be finally transferred to a real robot platform. Tests done in the simulator showed that the implemented methods are applicable to bring the bed to the desired goal taking into account the reaction of the person following the transport.

Camping and caravanning is practiced by a segment of the population in South Africa. Various articles in the caravan and outdoor life magazine published in South Africa have indicated that municipal caravan parks are not providing the same facilities and service as was provided in the past .With this background the hypothesis was established as being, the facilities at municipal caravan parks such as Hendon Park are deteriorating due to lack of government commitment and funds. The objectives of this research was determined as being whether (1) it is economically viable for the municipality to continue to utilise the existing land as a caravan park or, (2) it is more beneficial to the taxpayer for the municipality to sell the prime land to a developer or, (3) it is in the best interest of the municipality and /or the community to sell the property to a private company for upgrading the facilities to meet campers requirements The scope of the investigation was determined and includes questionnaires to campers, as well as interview’s with various stakeholders. The researcher also considered various management strategies suggested by strategist David, Fry, Lambert and Stock and Massey that could be used by Hendon Park management to enhance the operation of the Caravan Park under their control and thus a suggested management strategy was compiled. A specific window period to gather the information was decided as being the Easter Holiday period as this was the period that all caravan parks in Cape Town are at full capacity and thus this was the best opportunity to gather the information as the target (campers) would be camping in great numbers. Finally the results was analysed and a conclusion was drawn. Specific recommendations were then proposed by the researcher to be implemented by the staff of Hendon caravan park.

As science and technology continue to advance, innovative developments in transportation can enhance product safety and security for the benefit and welfare of society. The federal government requires every commercial truck to be inspected before each trip. This pre-trip inspection ensures the safe mechanical condition of each vehicle before it is used. An Unmanned Aerial Vehicle (UAV) could be used to provide an automated inspection, thus reducing driver workload, inspection costs and time while increasing inspection accuracy. This thesis develops a primary component of the algorithm that is required to implement UAV pre-trip inspections for commercial trucks using an android-based application. Specifically, this thesis provides foundational work of providing stable height control in an outdoor environment using a laser sensor and an android flight control application that includes take-off, landing, throttle control, and real-time video transmission. The height algorithm developed is the core of this thesis project. Phantom 2 Vision+ uses a pressure sensor to calculate the altitude of the drone for height stabilization. However, these altitude readings do not provide the precision required for this project. Rather, the goal of autonomously controlling height with great precision necessitated the use of a laser rangefinder sensor in the development of the height control algorithm. Another major contribution from this thesis research is to extend the limited capabilities of the DJI software development kit in order to provide more sophisticated control goals without modifying the drone dynamics. The results of this project are also directly applicable to a number of additional uses of drones in the transportation industry.
