Our interest lies in more efficient and advanced transportation and terminals, as globalization and new trends require effective solutions.The aim of our work is to explain the need for information technology applications in road haulage and associated terminal operations. Furthermore, we analyses terminal and applied information technology.
Sjuksköterskans erfarenheter av mötet med patienter med ett annat modersmål : - En litteraturöversikt
Background: Running economy is one of the key factors to achieve top performance in endurance events. Little evidence exists for improving running economy using high-intensity interval training while running. Objectives: The purpose of this study was to examine how HIIT affects running economy and VO2max. Method: 14 well-trained athletes (age 35 ± 8,9 years, height 175 ± 11,7 cm and weight 69 ± 12,2 kg) were divided into two separate groups (HIIT and Control). HIIT group performed 3 HIIT exercises every week for 4 weeks and Control group continued with their separate training programs consisting of mostly traditional endurance training. Results: Running economy showed no improvement in HIIT (pre 38,62 and post 38,62 ml/kg/min, p=1.00) but Control improved (pre 45,41 and post 43,37 ml/kg/min, p=0,03). VO2max decreased in HIIT (mean 61,32 to 60,84 ml/kg/min) and in Control (mean 61,99 to 58,47 ml/kg/min)..

BIM på Trafikverket : Förslag till en utvidgad investeringsprocess
2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.
Avståndets inverkan på styrningen: -en fallstudie hos Vin & Sprit
The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.

Syftet med studien var att beskriva specialistsjuksköterskors erfarenheter av att vårda kritiskt sjuka personer inom flygmedicinsk transport. Totalt intervjuades sju intensivvårdssjuksköterskor vid två sjukhus med helikopterverksamhet knutna till sig. En kvalitativ tematisk innehållsanalys utfördes på intervjuerna och resulterade i ett tema och sex kategorier. Temat som framkom var Säker intensivvård under flygmedicinsk transport. Kategorierna som framkom var Att egen erfarenhet och teamsamarbete behövs i svåra situationer, Att ställas inför dilemmat om närstående kan närvara eller ej, Att känna patientens och egen rädsla, Att uppleva vårdmiljön som en intensivvårdsplats med begränsat utrymme, Att en högljudd miljö försvårar kommunikationen under pågående flygtransport, Att planera och kontrollera för att minimera risker.
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
Utveckling av differentierade transportersättningar för rundvirskestransporter med lastbil
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.
Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm
When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.
Påverkan på energianvändning och termisk komfort vid reglerinstabilitet
The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.
Predicerar organisationsrättvisa och work locus of control hälsa hos kollektivanställda män och kvinnor
Ett högt ohälsotal i arbetslivet innebär stora kostnader för samhället, arbetsgivare och även för de anställda. Forskningen inom detta område har flyttat fokus från att studera ohälsa till att istället studera hälsa och vilka faktorer som befrämjar hälsa i arbetslivet, de så kallade friskfaktorerna. Föreliggande studies övergripande syfte var att studera om upplevelsen av organisationsrättvisa och personlighets¬faktorn work locus of control predicerar upplevd hälsa hos kollektivanställda män och kvinnor. Studien genomfördes utifrån ett kvantitativt perspektiv med 103 deltagare som besvarade en enkät. Svarsfrekvensen var 22,5 % och resultatet visade att work locus of control predicerar upplevd hälsa för männen och procedural rättvisa predicerar upplevd hälsa för kvinnorna.
Automatisk bedömning av reglerkretsarsprestanda
In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.
Energieffektivisering av linjesjöfarten till och från Tasmanien
Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.
Biological control of powdery mildew in greenhouse produced cucumber : an evaluation of two microbiological control agents
Powdery mildew is a serious problem in both field and greenhouse cucumber production and
can cause serious infection and radically reduced yields. Today, powdery mildew is the main
disease in greenhouse produced cucumber.
Disease control should preferably be both efficient and environmentally friendly, which is not
easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological
control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties.
Biological control can be described as the suppression of damaging activities inflicted
of a harmful organism by one or more other organisms, which are called antagonists or natural
enemies. In Sweden, there are currently no registered biological control products available
to control cucumber powdery mildew.
The aim of this study was to investigate the effect of two biological control products in order
to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level
in greenhouse produced cucumber. In the experiments, different application regimes were also
studied.
Vasakronan: Det bästa av två världar
Mergers and acquisitions are common phenomenon in today´s society in order to increase shareholder value. Two years ago a fusion of Sweden´s two largest companies in the industry of real estate took place and even though three out of four mergers and acquisitions financially fail this certain case turned out highly successful. The aim of this thesis is to examine how the organizational structure and the management control have been designed and characterized the organizational performance and furthermore what are the success factors of the integration. By studying an acquisition and its potential effects on organizational structure and management control parallel to a model that describes the best practice guidelines for managers to successfully deliver value from their acquisitions, it can be shown that an acquisition has direct effects both on the acquirer and the acquired company and thus the new organizational structure. The main results, thus, is that through active leadership, increased specialization, and more decentralized and thus efficient management control a new organization has emerged consisting of the best features of two separate worlds..
