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.

Visualisering av FRAM

The Functional Resonance Accident Model is a method developed to analyze complex systems for the purpose of accident prevention. In FRAM-analysis a visualization of the complex system is created as an aid for identifying points of interaction in the system where the risk of accidents is high, and to determine where preventive measures are to be placed. FRAM Visualizer is a computer program developed as a tool for creating such visualizations.Many usability problems have been identified in FRAM visualizations created both manually according to established method and by using the FRAM Visualizer software. The purpose of this paper is to give a basis for how FRAM visualizations can be improved in accordance with usability criteria for use in future qualitative studies.The author suggests alterations to the FRAM visualization to resolve usability issues identified in previous articles and to achieve usability goals derived from visual communication theory. The design process is guided by established design principles.

Balanserat styrkort : Att förmedla vision och strategier inom divisionen för flygtrafiktjänst vid svenska Luftfartsverket

The purpose of this essay is to investigate how well vision and strategies communicates from division level to underlying business unit levels with focus on the Balanced Scorecard Concept. The investigation was carried out within the ANS division and two of its underlying business units at the LFV Group (Swedish Airports and Air Navigation Services). ANS is responsible for the air navigation services in Sweden and the production of the services is carried out of the business units AER (En Route) and ATA (Tower and Approach). With Air Navigation Services means supervision and conducting air traffic mainly within national air space. The purpose of the services is to insure that air traffic could be carried out in a safe way.The Balanced Scorecard was introduced for the first time in the beginning of the 1990´s.

Affärsmodeller inom IP-telefoni

When communications traffic increasingly turned into data, IP telephony became a disruptive technology for the telecommunication business. IP telephony was a hot topic when voice over IP services started to become available to consumers in the 1990s. The new technology changed the rules of the game and many new actors entered the market.The purpose of this study is to describe, study, and analyze how the business models of the Swedish telecom sector developed in the middle of the 2000s. The study is delimited to the Swedish consumer market for telephony.The study is built mainly upon deep interviews with 24 prominent persons in the telecom sector in 2006. To aid understanding, two telecom companies that have been chosen to represent different kinds of actors are described and analyzed more closely.

Riskhantering i projekt : Modell för uppföljning

In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket.The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan).

Hör du vad jag ser? -Kommunikation för koordination av skadeplatsarbete genom awareness

Skadeplatsarbete är en arbetsform med en speciell karaktär. Det som formar denna karaktär är dess uppkomst genom inträffandet av en olycka av något slag. Detta medför att olika aktörer och aktörsgrupper temporärt stålar samman och genomför ett samarbete med utgångspunkt från platsen för det inträffade. Ambulans, brandkår, polis och SOS Alarm AB är de vanligaste aktörsgrupperna på en skadeplats. Att rädda liv är ett samarbete mellan olika aktörsgruppers på en skadeplats.

Öppen dagvattenhantering i urbana miljöer :

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks.

Ny bebyggelse på Almöstrand - Planering av bostadområde i kuperad terräng

Tjörns kommun har planer på att bebygga Almön, en halvö belägen på nordöstra Tjörn intill Tjörnbron. Projektet är avgränsat till området som benämns Almöstrand, vilket är Almöns västra strand, en kuperad sluttning med kraftigt lutande partier som idag till största del består av skogsmark. Syftet är att undersöka hur man på olika sätt kan planera vägsträckningen i området, samt placering och utformning av hus, med hänsyn till en rad olika parametrar. Undersökningen visualiseras slutligen i 3D, i form av renderingar från Revit Architecture samt en fysisk modell.Initialt genomfördes en utredning för att ge beslutsunderlag till projektet. Vidare gjordes en fallstudie vilken har använts som referens och inspiration till arbetet.

This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

En intuitiv & lättillgänglig flyktmask för gruvmiljö

I have always lived around mines and around people work­ing with mines. They are a natural part of my life and, inev­itably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.

Kontraheringsplikt inom förmögenhetsrätten ? Avtalsfrihetens gränser

Swedish contract law is based on the main principle of freedom of contract, which means that a contract is built on a voluntary agreement of both parties. There are exceptions from the principle of freedom of contract. In some instances a party is obliged to contract (kontraheringsplikt), which also is the subject for this paper. Kontraheringsplikt can be described as an obligation for one of the parts in a relation to come to an agreement under normal circumstances with everyone who ask for it. The cases of kontraheringsplikt are rather different.

Karakterisering av bioslam för modellering av biogasproduktion

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.
