Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

The purpose of this essay is to investigate if signage for tourists in Stockholm is enough to easily find your way to attractions and public modes of transport and how the city works with the issue. Triangulation was chosen for the essay, that is, a mix of qualitative and quantitative methods. A survey of 100 tourists was carried out in the Old town of Stockholm and interviews were made with stakeholders in the tourism industry and signage policy in Stockholm. The survey showed that most of the tourists found it easy to find their way in Stockholm and that they were content with the signage. Few of the tourists thought it was difficult to find their way in Stockholm.

Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.

Syfte: Huvudsyftet med uppsatsen är att undersöka ett företags givna transportstrukturs miljöpåverkan i växthusemissioner eller CO2e. Detta genom att med hjälp av olika verktyg och teorier ta fram ett antal scenarion som har en lägre miljöpåverkan än befintlig transportstruktur. Det sekundära syftet är att ta fram modeller som hjälper företaget att ta hänsyn till de ekonomiska kostnader som kan vara kopplade till en omstrukturering av transportstrukturen.Metod: Kvalitativa intervjuer om grön logistik och vilka verktyg som används i detta arbete samt en kvantitativ datainsamling i beräkningar av emissioner med hjälp av NTMCalc.Slutsatser: Ett antal olika scenarion togs fram där miljöpåverkan uppskattades, utifrån dessa valdes 5 stycken ut som hade en lägre miljöpåverkan än befintlig transportstruktur. I dessa utvalda scenarion tas hänsyn till ytterligare faktorer som exempelvis ledtider, hur många landsgränser som måste korsas, tätortskörning etc. Då det inte finns ett ekonomiskt underlag för vad ett transportstrukturbyte skulle kosta förs det en diskussion med rekommendationer över åtgärder vid ett byte av transport..

Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.

ABSTRAKTBakgrund: Interhospitala transporter innebär ökade risker för medicinska komplikationer för den kritiskt sjuka patienten. Inom ramen för intensivvårdsjuksköterskans kompetens ingår att kunna utföra omvårdnad till den kritiskt sjuka patienten under interhospitala transporter. Sjuksköterskor med specialistutbildning inom intensivvård kan under transport av kritiskt sjuka patienter uppleva oro. För att kunna förbättra omhändertagandet av patienten är det av intresse att ta reda på om det finns fler perspektiv och upplevelser av arbetet vid denna komplexa situation som en interhospital intensivvårdstransport innebär.Syfte: Syftet med denna studie var att beskriva intensivvårdssjuksköterskors upplevelse av att vårda kritiskt sjuka patienter under markbundna interhospitala transporter.Design: Denna studie har en kvalitativ design.Metod: Semi-strukturerade intervjuer med åtta intensivvårdssjuksköterskor spelades in och transkriberades för att sedan analyseras med tematiskt analys.Resultat: Ur analysen konstruerades tre huvudteman. Att sträva efter att ha kontroll över situationen, Betydelsen av ett bra samarbetet i teamet och Att utmanas i sin yrkeskompetens.Slutsats: Resultatet visade att transportera kritiskt sjuka patienter mellan sjukhus kan ge upphov till både negativa och positiva känslor.

Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with different conditions to get a good flow on their transports. Today the transport pricing is very general and the payment consists of the unit round wood they are transporting and the distance of the transport. The purpose of this study were, from the freighter and the haulage company?s perspective, try to find ways to change the today applied transport pricing to more differentiated and compare them to historic payment of transportation.

Everyday life mobility of elderly people ? opportunities, restrictions and sustainable urban visions aim to examine and describe elderly people?s movement patterns, their opportunities and restrictions of reaching high mobility and accessibility, and their attitude towards various sustainable urban visions. This paper is based on an approach of time-space geography as it covers the topic of movements in time-space, explained and developed using the concepts of mobility and accessibility. To examine elderly people?s attitude towards sustainable urban visions, this paper also takes approach on theories such as New Urbanism, mixed-use and the compact city.The method used in the study is an interweaving of a time geographic diary and qualitative interviews, where the respondents are six retired people between 68 and 77 years old living in Gothenburg city.

The objective of the thesis is primarily to conform and encode a digital signal to be controlled by software. The idea is to transport today?s tracesignal through the IP-network instead of cable-net. In this report I will suggest a possible solution to get a fully passed result with no peculiar time delay. I will also suggest some ideas for a future work with the new tracesystem..

Genom utvecklingen av infrastrukturen i storstadsområdena ställs idag allt större krav på masstransportsystemen som binder samman olika områden. En viktig aspekt är att upprätthålla en god säkerhet samtidigt som persontransporten måste utföras så snabbt och effektivt som möjligt. Detta ställer stora krav på den som utför persontransporter. Syftet med denna studie var att undersöka tunneltågförares attityder och subjektiva normer till säkerhetsarbetet inom Veolia Transport AB, mäta deras beteendeintentioner till säkerhetskulturen och deras upplevda säkerhetsbeteende. Studien utgick från Ajzen & Fishbeins (1975) teori om beteendeintentioner, Reasons (1990) teori om människor och säkerhetskulturer, samt Westrums (1992) karaktäristika om utvärdering av organisationsstrukturer.

Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.

When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.
