Rullande landsväg

This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.

Utvärdering av en interaktiv brand- och räddningsinstruktion genom tematisk analys baserad på användarintervjuer och heuristisk utvärdering

Syftet med rapporten är att utvärdera en interaktiv brand- och räddningsinstruktion som framförallt används inom försvarsmakten. Utvärderingen gick ut på att ta reda på hur användarna använder instruktionen och hur de vill att den ska utvecklas i framtiden för att möta deras behov. Utvärderingen genomfördes genom intervjuer med sju användare från olika delar av landet samt en heuristisk utvärdering utifrån Nielsens tio användbarhetsprinciper och med hänsyn till Sweller och Chandlers ?cognitive load theory?. Resultatet visade att instruktionen framförallt används som uppslagsbok och att användarna vill se en utveckling av instruktionen där den blir större och omfattar mer information, till exempel om haverier och utländska luftfartyg och att text och illustrationer i instruktionen är uppdaterad och korrekt.

Konstruktion av provladdareför singelmolekyldetektor

This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea?s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task.The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument.

Interaktionskvalitet - hur mäts det?

Den tekniska utvecklingen har lett till att massiva mängder av information sänds, i höga hastigheter. Detta flöde måste vi lära oss att hantera. För att maximera nyttan av de nya teknikerna och undkomma de problem som detta enorma informationsflöde bär med sig, bör interaktionskvalitet studeras. Vi måste anpassa gränssnitt efter användaren eftersom denne inte har möjlighet att anpassa sig till, och sortera i för stora informationsmängder. Vi måste utveckla system som gör människan mer effektiv vid användande av gränssnitt. För att anpassa gränssnitten efter användarens behov och begränsningar krävs kunskaper om den mänskliga kognitionen.

Experimentell undersökning av provkroppar för trälimfogar

This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper

The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..

Ombyggnad av lägenheter i ett 1950-tals flerbostadshus till kontorsbyggnad

The report aim to increase awareness of factors that have a major role whenremodelling an apartment building from the 1950s to offices.The thesis can be used for future projects when remodelling apartments to offices.The report can provide ideas and inspirations on how this can be done in aneffective way, ie . A way that does not require rebuilding the supporting structure,but only non bearing walls. The thesis also gives insight on the parts that will needto be supplemented from Boverket?s requirements in terms of accessibility,acoustic and fire requirements.The methods used in this thesis are literature studies, case study and sketch work.In the literature studies, the primary sources were Boverkets byggregler BBR, andArbetsmiljöverkets föreskrift AFS 2009:2 but other literature were also used. Theprimary items were chosen from the literature studies and they were furtheranalysed in the sketch work.

Hisskärna av skalväggar i höga byggnader : Ett alternativ till den platsgjutna kärnan

A common way to stabilize high rise buildings is to use an elevator core built of concrete. Today, we use to build these elevator cores of in-situ concrete. Precast concrete twin wall (double wall) is a semi-finished product that has become more common in recent years. This diploma work studies how the twin wall works out as structural elements in an elevator core. The work also shows some possible ways of designing twin walls and highlights some important parts of the design that will be vital to the stability of the building.    The result shows that it is important to think through where the element joints should be placed.

Sjuksköterskans arbete med Manchestertriage : arbetstillfredsställelse och kompetens

Background: Triage is the sorting of patients according to the severity of medical assessment. Triage has a long history of use in Anglo-Saxon countries but is a fairly new method in Sweden. Researchers have described the Manchester triage group method (MTS) and a literature review of the concept; working contentment and competence focusing on triage. Aim: The ambition with this study was to describe a number of triage nurses working conditions. The research questions were; working with MTS- does it bring work contentment? What kind of competence is needed? Method: Data was collected from 74 triage nurses by a questionnaire containing 37 questions and two questions provided the nurses the opportunities to describe their triage experiences.

Anhörigvårdares Upplevelser Av Sitt Vardagliga Arbete

The family and relatives caring of older people in Sweden lies on an old tradition. By legislation the responsibility for the older people has gone through a development from the family to the society. According to the new social service law (2000) it is not that clear that the utmost responsibility lies on the society. According to the social service law ( 5th chapter, 10 §) the municipality should ease things up by giving support and relief for relatives taking care of older people, prolonged ill and function disabled people. The purpose with the study was to examine how the family care givers are finding their everyday work and their experience of the support that the society is giving.

Barnavårdsutredningar i tid eller otid?

The aim of the study was to investigate social workers and managers experiences of ending child welfare investigations within the statutory period of four months. We also investigated their experience of investigation time is used in practice. To get answers for our purpose, we conducted a qualitative study. We strategic selected three social workers and four managers to our interviews.The results showed that both social workers and managers have experience with child welfare investigations that are not completed within the statutory time. A township that departed had no experience.

Tillförlitlighet hos trafikolycksklassificering

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.
