Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

The purpose of this study was to gather knowledge about the functioning of the rein tension meter and test it for future studies of match and mismatch between rider and horse. We looked specifically into the possibilities to use a rein-tension meter to determine the quality of cooperation between horse and rider. We examined whether a rider shows a specific tension pattern and also if certain patterns could be recognised for a specific horse. During the study, a manual with pictures and text was written to support the practical use of the meter. The manual describes in a simple way the first steps in the installation and use of the meter.

The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations.

Bakgrund och syfteUnder en fotbollsmatch rör sig spelarna någonstans mellan 9-12 km i olika hastigheter. Ungefär 10 % av denna sträcka genomförs genom löpningar av hög intensitet, där de flesta sprinter sker kring 2 sekunder. Under 2 sekunder hinner en spelare ungefär 10-15 meter, beroende på spelarens accelerationsförmåga. Studier har visat ett samband mellan hopp och sprintförmåga både bilateralt och unilateralt. Dock är det få studier som följt förloppet från start till 30 meter med mellantider om varje 5 meter och få studier genomförda unilateralt hos fotbollsspelare.

At times when the electricity supply system is highly loaded, electricity is more expensive.

Ett Pure-Car/Truck-Carrier fartyg med kapacitet för 6000 bilar på en har prospekterats. Fartyget skall huvudsakligen gå mellan Ostasien, Europa och Nordamerika.I problemformuleringen beskrivs vilka utmaningar och förutsättningar som har varit, samt lösningsmetoder och begränsningar. Under Analys beskrivs hur tankegångarna har varit mer detaljerat och illustrerat med figurer. Analysen har i stort sett gjorts i den ordning som underrubrikerna följer. Nästan alla beräkningar är gjorda i MATLAB enligt kända metoder; många hänvisningar görs till respektive metod och MATLAB-kod som återfinnes i bilagorna.

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

Idrottsrörelsen är den största och mest livskraftiga folkrörelsen i Sverige. Prestationsförmågan och kraven har ökat inom idrotten och det pågår en ständig jakt efter nya talanger. Många, oavsett idrott, tränar väldigt mycket och på ett likartat sätt, men får sällan någon feedback på träningseffekten. Fysprofilen kan hjälpa till att optimera och styra träningen rätt genom att identifiera varje individs fysiska förmåga. Löp- och snabbhetskraven i lagsporter karaktäriseras mer av riktningsförändringar än av löpning rakt fram.

The sea-level is rising due to climate change. This report inquires into the possibleconsequences of sea-level rise in Värmdö and its archipelago with particular focus on roadsand buildings. Four scenarios with a sea-level rise of 0.5, 1.5, 2.5 meter and a worst casescenario of 3.9 meter are analyzed using a geographic information system (GIS) calledarcMap. The report also examines how Värmdö is taking into account future sea-level rise intheir planning today. The report´s findings show that uplift and sea-level rise cancel eachother out in the scenario with a sea-level rise of 0.5 meter, but that a number of more or lessimportant roads and buildings will be affected by a rise of 1.5 meters.

Fårön ligger strax norr om Piteå centrum och nyttjas för fritidsboende, permanent boende och som ett ströv- och naturområde. Idag förbinds ön till fastlandet över det 140 meter breda sundet av en lång bank och en cirka 10 meter lång betongbro. Den långa banken hindrar vattenströmningen i sundet och bidrar till en ökad uppgrundning. Bron är så smal att inga fordon kan mötas och även cyklister och gångtrafikanter upplever det besvärligt med mötande trafik på bron. Syftet med detta examensarbete har varit att för tre broalternativ undersöka vattenföringen i sundet, broarnas arkitektur, konstruktionslösningar och ekonomi och sedan utifrån dessa fyra parametrarna bedöma vilket utan broalternativen som är bäst lämpat att bygga.

The initial aim of the roll out of smart electricity meters in Sweden was to allow remote readings of the households? monthly electricity consumption for billing purposes. Since then the transition towards a smart grid has become a more prioritized matter. In the roll out of next generation smart meters more attention is therefore given to how the Distribution System Operator (DSO) can benefit from the meter through different smart grid applications. This study uses a qualitative research method to identify three general fields of application and 15 specific concepts corresponding to ways in which the DSO can create added value from the information provided by the smart meter.

ABSTRAKT  Det råder oklarheter om hur styrketräning för fotbollsspelare ska bedrivas på ett effektivt sätt. Syftet med studien var att undersöka hur fem veckors knäböjsträning med ?svänghjulsergometer (YoYo-squat)? påverkar styrke- och power relaterade prestationsfaktorer hos fotbollsspelare. Försökspersonerna var 16 manliga försökspersoner i åldern 16-19 år. De delades in i försöksgrupp (N=9) och kontrollgrupp (N=7).

This quantitative study aims to investigate whether there is a difference in the effect of the policy rate on the price per square meter for condominiums between small and large cities in Sweden. The study encompasses a total of seven Swedish municipalities, of which three located in large cities and four in small cities. Data regarding housing sales and additional variables have been collected for all municipalities, and the price per square meter is the dependent variable in the regressions performed on the dataset, which constitutes the empirical basis of the study. The aim is further to contribute to an increased understanding of how the effect of the policy rate might differ between Swedish cities and why. The results of the study show significant differences in how the policy rate affects the price per square meter in a small city compared to a large city, with the effect being greater in the latter.

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.
