Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

This report is a Master?s Thesis performed by Andreas Adolfsson and David Jacobsson atChalmers University of Technology. The purpose of this master?s thesis is to evaluate anew method for load-shedding, the voltage controlled underfrequency load-sheddingdeveloped by ABB. This report presents a comparison between conventionalunderfrequency load-shedding and this new method for load-shedding.

One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

En effektiv och lönsam logistik kan företag använda som en konkurrensfördel. Det gäller att hitta en balans mellan att exempelvis ge hög service till kunderna och samtidigt tvingas ta hänsyn till höga kostnader för lagerhållning. Denna uppsats syftar till att beskriva och analysera hur Peak Performance hanterar denna balans mellan logistikkostnader, kapitalbindning, leveransservice och miljö. Tre av dessa delar är hämtade från en modell av Lumsden (1998). Vi har därefter modifierat modellen och tillfört den fjärde komponenten, miljö.

The aim of this study is to evaluate whether the value of occupant load is over or under estimated when the Swedish general value for department stores, 0,5 person/m2, is used for dimensioning shopping centers. The data that was analyzed derives from seven shopping centers and one department store. A conservative method was used to calculate the occupant load factor. The analysis shows that two groups can be discerned: one group that is characterized by a lower occupant load factor that does not exceed 0,3 person/m2, and one group with a higher occupant load factor. Shopping centers with a higher occupant load factor are located centrally in large urban areas.

Syftet med denna undersökning har varit att underlätta för företaget Re-Load att presentera sin lastpall som produkt för potentiella kunder. Syftet har också varit att stötta Re-Load till att bli licenserad EUR-pall samt att successivt ersätta befintliga lastpallar och långsiktigt exekvera företagets affärsplan. Målet har varit att undersöka produkten avseende lönsamhet, miljöinverkan och hur den påverkade arbetsmiljön. Under-sökningen har genomförts med ett befintligt flöde där produkten använts och utifrån detta kunde en flödesstudie samt en komparativ produktstudie utföras med en alternativ lastpall. Med data hämtat ur detta flöde utfördes en investeringskalkylering, miljöberäkningar, subjektiva intervjuer samt dokumentation.

Vi står inför en förändring, att minska vårt beroende av fossil energi till förmån för en ökad användning av förnybar energi. Incitament i form av ökade punktskatter på fossilt bränsle påskyndar omställningen för företag till förnybar energi och- eller energieffektivisering av sin produktion. Konsekvensen blir en successivt fördyrad kostnad för produktion av fjärrvärme med eldningsolja till tillverkningsindustrin. Punktskatt på eldningsolja stiger med 41 procent, från 2010 till 2015 för företagen. Att konvertera befintliga oljepannor med träpulverbrännare är en lösning för att hålla produktionskostnaden nere och behålla sin konkurrenskraft.

To achieve peak performance as a young elite athlete, there are many psychological andphysical factors that have impact on human?s performance. Factors that affect theperformance interplay and interact must work to maintain ability to perform at its peak.The purpose of this study is to examine the factors that contribute to peak performance.Data collection method of the study has been done with a questionnaire, addressed toyoung elite athletes on a secondary school. It was 87 respondents who participated onvoluntary and anonymously conditions. The respondents consisted of men and womenbetween 16 and 19 years old.

Att skatta sannolikheter för extrema händelser är svårt eftersom de sällan inträffaroch underlaget att bygga skattningar utifrån är begränsat. Ofta används skattningsmetodergrundade på asymptotiska resultat från extremvärdesteorin som inte självklart äruppfyllda när man utgår från en verklig datamängd. I den här uppsatsen har en sådan metod, som kallas peak over threshold-metoden, jämförts med en modifierad metodsom inte bygger på sådan asymptotik; fastypsmetoden. I peak over threshold-metoden skattas den betingade sannolikheten att befinna sig långt ut i svansen av en fördelning med hjälp av en generaliserad paretofördelning. I fastypsmetoden skattas istället den betingade sannolikheten att befinna sig långt ut i svansen med en fastypsfördelning.

Background: In the martial art of Muay Thai, techniques are used with hands, elbows, knees and kicks. The contestants are divided into different weight classes and experience levels. The Swedish martial arts association has decided that techniques with elbow are not allowed in B-class. Why is it so?Objective: The aim of this study was to investigate whether the martial arts delegation decision to restrict techniques with elbows to the head in the B-class is justified.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
