Background: To reach the global goals of 2030, changes need to be maderegarding how decision makers decide to freight their goods. In Sweden,road traffic is held accountable for 90% of the carbon dioxide emissions.To help solve the problem with vast distances in Sweden's rural areas,scientists have researched the possibility of coordinating the transports.The research has shown that transports receive a more appropriate fill rate,lower transportation costs, and because of those two factors, lowered theircarbon dioxide emissions. Purpose: The purpose of this study is to lay a scientific foundation andpresent an example of a decision model. The decision model mainly aimstowards decision makers in rural municipalities but also companies thatwork toward these rural areas.  Methodology: This research undertook a qualitative research approach inan exploratory method. In order to ensure that the criteria’s and the prosand cons with coordinating freight transports the researchers interviewedkey persons for the rural municipalities in a semi structured or structurednature. Findings: The study has found the most relevant pros and cons with acoordination of freight transports and the criteria’s needed to build anexample of a decision model.  Conclusions: The theoretical and empirical data has been similar in many,but one stands out, and that is the increase of lead times as a negativefactor the rural areas, because of the coordination. The citizens andcompanies these rural areas are more interested in consistency andreliability. The study concluded the necessary criteria’s needed to build thedecision model. / Bakgrund: För att Sverige ska kunna nå sina uppsatta klimatmål innan år2030, behövs stora förändringar ske i hur vi skickar och transporterar vårtgods. Idag står Sveriges vägtrafik för 90% av de koldioxidutsläpp somsker av alla inrikes transporter. För att lösa problemet med de långaavstånden ut mot glesbygden har man undersökt möjligheten till attförsöka samordna varutransporterna som ska till glesbygdsområden.Tidigare varusamordningsprojekt har visat sig tillföra starka fördelar förtransportföretag som bland annat bättre fyllnadsgrad och reduceradetransportkostnader, samtidigt som att man minskar utsläppen kopplade tilltransporter. Syfte: Studiens syfte är att lägga en vetenskaplig grund förvarusamordning samt presentera en beslutsmodell. Beslutsmodellen riktarsig mot kommunala beslutsfattare samt beslutsfattare inom företag somjobbar mot glesbygder.

Dessa för- ochnackdelar är tänkta att synliggöra varusamordningens möjligheter samttillkortakommanden.Vidare presenteras en beslutsmodell med förslag på beslutskriterier somtagits fram från de teoretiska och empiriska information som insamladestill studien.

Over the last decade, extensive research efforts have been placed on performance evaluation and the benefits of innovative CV applications. Findings indicate that CV technology can effectively mitigate the safety, mobility, and environmental challenges experienced on transportation networks. Most of research evaluated CV technology through simulation studies. However, a field study provides a more ideal method of assessing CV technology effectiveness. Therefore, a field study to obtain the actual effectiveness of CV technology was warranted, to validate previous findings, and to add to the body of knowledge surrounding this topic. This thesis presents both a field study and simulation evaluation of the effectiveness of CV smartphone technology on a 1.1 mile segment of State Road 121, containing five intersections, in Gainesville, Florida. Field observations were conducted using a CV application, developed by Connected Signals, Inc., that uses a smartphone application, called EnLighten, to communicate intersection information to driver’s smartphone, which serves as a vehicle on-board unit. Traffic operation and safety performance was evaluated using start-up lost time, discharge distribution model, and speed harmonization. Findings show that the CV smartphone technology improved intersection performance with a reduction in start-up lost time of approximately 86%. Additionally, driving safety improved with a reduction in speed variability by nearly 61% between vehicles in a specific lane for a 100% CV penetration rate. Cost analyses of deploying CV smartphone technology indicate that implementation may result in an average total economic cost savings associated with crashes of nearly $6.8 million at the study site, and approximately $5.6 billion statewide. Findings of the simulation evaluation revealed that the CV technology improved performance of intersections operating at a Level of Service (LOS) B or better, compared to lower operating levels. Operational performance improved at intersections operating at a LOS C with a 30% to 60% CV penetration rate.

Abstracts in English, Afrikaans and Zulu / Emalahleni, situated in Mpumalanga Province in South Africa, has been exposed to over a hundred years of continuous mining of coal. Evident challenges include the sterilisation of land due to underground fires, polluted water, surface collapse and acidification of topsoil (McCarthy & Pretorius, 2009:65; Schneider, 2016:1). The researcher reviewed existing literature to determine existing frameworks thereby identifying gaps. Consequently, the researcher found no published decision-making framework that may assist coal mining companies in South Africa to preserve the environment and its natural resources. Research objectives and research questions as well as a preliminary framework were developed. A qualitative research design was adopted in which personal interviews were employed to gather primary data from coal mining companies in South Africa whilst a focus group was utilised to validate the framework. Personal interviews established that majority of participants were not familiar with EMA and that EMA tools such as ISO, LCC and the green strategy would add value to the coal mining industry. Furthermore, there was no consistency in the application and adherence to environmental regulations. Participants also indicated that current processes employed by the coal mining industry were not effective in saving the environment. In validating the framework, the focus group established that tools (methodologies) will serve the purpose as indicated in the framework and that the framework was relevant to the coal mining industry. There was a general consensus that regulatory aspects can go a long way in controlling adverse effects on the environment, so long as these would be applied to all industries, and not only the coal mining industry. Input from the focus group assisted in enhancing the framework by testing the associations and links. Key recommendations indicated that coal mining companies should incorporate environmental accountability in their corporate decisions; education and training should be conducted in all coal mining companies in order for these companies to know the type of information that they need to utilise in identifying waste. Future research could include a similar study of statistical nature that will test the decision-making framework developed in this study. Going to the coal mining companies to exercise the framework on a real-life setting. / Emalahleni, hu wanala kha Vundu ḽa Mpumalanga Afrika Tshipembe, ho ṱanea lwa miṅwaha i fhiraho ḓana nga migodi ya malasha ine ya khou bvela phanḓa.

As gevolg hiervan raak grond steriel weens ondergrondse brande, word water besoedel, sak die grondoppervlak in en versuur die bogrond. In die literatuur kon die navorser kon geen besluitnemingsraamwerk waarvolgens Suid-Afrikaanse steenkoolmaatskappye die omgewing en natuurlike hulpbronne bewaar, vind nie. Navorsingsdoelwitte is gestel, en navorsingsvrae en ʼn voorlopige raamwerk is opgestel. ʼn Kwalitatiewe navorsingsontwerp is gevolg en persoonlike onderhoude is by Suid-Afrikaanse steenkoolmaatskappye gevoer om die primêre data te versamel. Die geldigheid van die besluitnemingsraamwerk is met ʼn fokusgroep getoets. Uit die persoonlike onderhoude het geblyk dat die meeste deelnemers onbekend was met omgewingsbestuuraanspreeklikheid (OBA) en dat hulle nie geweet het dat hulpmiddels soos ISO, ʼn lewensikluskosteberekening (LSK) en ʼn groen strategie waarde tot die steenkoolbedryf kan toevoeg nie. Afgesien hiervan is omgewingsregulasies nie eenvormig toegepas en nagekom nie. Deelnemers het eweneens laat blyk dat die steenkoolbedryf se huidige prosesse gemik op omgewingsbewaring oneffektief is. Die fokusgroep het vasgestel dat die hulpmiddels (metodologieë) die oogmerk van die raamwerk verwesenlik, en die raamwerk dus geldig en van groot nut vir die steenkoolbedryf kan wees. Daar was eenstemmigheid dat die regulerende aspekte die nadelige uitwerking van mynbouwerksaamhede op die omgewing kon beheer, op voorwaarde dat dit nie alleen in die steenkoolbedryf nie, maar in alle bedrywe toegepas word. Die raamwerk is aan die hand van die fokusgroep se insette verfyn deur die verbande en skakels te toets. Die belangrikste aanbevelings behels dat omgewingsaanspreeklikheid deel van steenkoolmaatskappye se besluitneming moet uitmaak, en dat alle steenkoolmaatskappye opgelei moet word in die soort inligting waarvolgens bepaal word wat afval is. In die toekoms kan ʼn soortgelyke statistiese studie onderneem word om die besluitnemingsraamwerk wat in hierdie studie ontwikkel is, te toets. Dit sal behels dat die raamwerk in lewensegte omstandighede by steenkoolmaatskappye ondersoek word. / Business Management / D. B. L.

This thesis addresses the three principal questions concerning the development of CT urography for investigating haematuria and each question is the subject of a separate chapter. The questions are: What is the reasoning behind using CT urography? What is the optimum diagnostic strategy using CT urography? What are the problems with using CT urography and how may solutions be provided? Haematuria can signify serious disease such as urinary tract stones, renal cell cancer, upper tract urothelial cancer (UTUC) and bladder cancer (BCa). CT urography is defined as contrast enhanced CT examination of kidneys, ureters and bladder. The technique used here includes unenhanced, nephrographic and excretory-phases for optimized diagnosis of stones, renal masses and urothelial cancer respectively. The reasoning behind using excretory-phase CT urography for investigating haematuria is based on results showing its high diagnostic accuracy for UTUC and BCa. Patients with haematuria are classified as low risk or high risk for UTUC and BCa, by a risk score, determined by the presence/absence of risk factors: age > 50 years, visible or nonvisible haematuria, history of smoking and occupational exposure. The optimum diagnostic strategy for patients at high risk for urothelial cancer, uses CT urography as a replacement test for ultrasonography and intravenous urography and as a triage test for flexible and rigid cystoscopy, resulting in earlier diagnosis and potentially improving prognosis. For patients at low risk, ultrasonography, unenhanced and nephrographic-phase CT urography are proposed as initial imaging tests. Problems with using CT urography include false positive results for UTUC, which are eliminated by retrograde ureteropyelography-guided biopsy, an innovative technique, for histopathological confirmation of diagnosis. Recommendations for the NHS and possible future developments are discussed. CT urography, including excretory-phase imaging, is recommended as the initial diagnostic imaging test before cystoscopy for patients with haematuria at high risk for urothelial cancer.

The thesis will discuss the Systems Engineering phase of an original Conceptual Design Engineering Methodology for Aerospace Engineering-Vehicle Synthesis. This iterative phase is shown to benefit from digitization of Integrated Product&Process Design (IPPD) activities, through the application of Product Lifecycle Management (PLM) technologies. Requirements analysis through the use of Quality Function Deployment (QFD) and 7 MaP tools is explored as an illustration. A "Requirements Data Manager" (RDM) is used to show the ability to reduce the time and cost to design for both new and legacy/derivative designs. Here the COTS tool Teamcenter Systems Engineering (TCSE) is used as the RDM. The utility of the new methodology is explored through consideration of a legacy RFP based vehicle design proposal and associated aerospace engineering. The 2001 American Helicopter Society (AHS) 18th Student Design Competition RFP is considered as a starting point for the Systems Engineering phase. A Conceptual Design Engineering activity was conducted in 2000/2001 by Graduate students (including the author) in Rotorcraft Engineering at the Daniel Guggenheim School of Aerospace Engineering at the Georgia Institute of Technology, Atlanta GA. This resulted in the "Kingfisher" vehicle design, an advanced search and rescue rotorcraft capable of performing the "Perfect Storm" mission, from the movie of the same name. The associated requirements, architectures, and work breakdown structure data sets for the Kingfisher are used to relate the capabilities of the proposed Integrated Digital Environment (IDE). The IDE is discussed as a repository for legacy knowledge capture, management, and design template creation. A primary thesis theme is to promote the automation of the up-front conceptual definition of complex systems, specifically aerospace vehicles, while anticipating downstream preliminary and full spectrum lifecycle design activities. The thesis forms a basis for additional discussions of PLM tool integration across the engineering, manufacturing, MRO and EOL lifecycle phases to support business management processes.
