Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank

The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.

Lärarledarskap i klassrummet : En etnografisk inspirerad studie med Critical Incident Technique som analysverksyg för att synliggöra strategier hos en specifik lärare

The purpose has been to investigate leisure-time centers actual work on children with attention deficit disorder. In addition, the study strives to make leisure-time centers way of working, in relation to their assignments, visible. The study has also compared how the leisure-time centers work and what the research says. The survey was conducted with the help of three exploratory interviews with pedagogues and three-piece observations at the leisure-time centers. It was carried out at three different schools in two counties in Sweden.The results of the survey show that the schools are trying to create clear procedures, though the centers succeed with this in varied degrees.

Public service vs Kommersiell TV. SVT, TV4-gruppen och MTG: En kvalitativ fallstudie om de ledande aktörerna på den svenska TV-marknaden och deras marknadsorientering.

The Swedish TV broadcasting market is constantly changing together with the players in it. The questionto be answered by this paper is how the players in the market handle these changes and to what extentthe players are changing the market. Also, are there any differences between the public service andcommercial players in this aspect? The purpose of this paper is to create a better understanding of theSwedish broadcasting market and its player's market orientation. Through case studies of the three mainbroadcasting companies, SVT, TV4-gruppen and MTG, the market is analyzed from their perspective.The conclusions from the analysis show that there are differences in the market orientation betweenpublic service and commercial players, where the commercial companies are more market driven..

Socialarbetares syn på datorspelande ungdomar : En intervjustudie om socialarbetares problematisering av ett nytt fenomen

The purpose of our study is to describe and understand whether, and if so, how social workers in school and in social services construct computer gaming adolescents as a social problem. We chose social workers who encounter adolescents with different problems. We have conducted qualitative interviews with vignettes to capture the social workers' reasoning about computer gaming adolescents and how they handle this in their work. The study shows that all social workers we interviewed had encountered adolescents with troubling computer gaming habits. In the study, all agree that computer gaming becomes a problem when it leads to deviant behaviour such as not going to school, staying up all night and so on.

Effektivisering av mellanspänningsnät med enkla medel : Feldetektorer och sommardriftläge

Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

Energianvändning i badhus : Simulering och jämförelse av gamla och nya system

Every year new premises are built in Sweden, and even if they are made as energy efficient as possible, this will not reduce the energy demands, but the rate of the increase of the energy use will be reduced. One type of facility in Sweden that is a major energy user is public baths, and this makes public baths an interesting facility to study more closely. There are around 500 public baths in Sweden and about 75 % of those can be seen as older baths with large need of renovation, and they all require a high level of energy efficiency measures. To show how the energy demand increase or decrease depending on the changes chosen to be made, the simulation application IDA Indoor Climate and Energy was used. Simulations were made and compared for several cases, with two extreme cases as starting points.

Maskulinitet och makt : En studie av Georgs maskulinitet i Lars Noréns drama Natten är dagens mor

In the following essay I have read the drama Natten är dagens mor (The Night is the Day's Mother) by Lars Norén. My main focus has been on the older brother Georg. By using post structuralist gender theories I have sought answers to the following two questions: How is Georg's masculinity constructed and maintained, when seen from a gender perspective? What power structures arise between Georg's and the other men's masculinities? In my analysis I have approached Georg via three perspectives. First, I have by the help of Judith Butler's theory concerning gender performative actions tried to define the men's gender codes.

Människan och lärarprofessionen : En livsberättelse

The aim of this essay is to get a deeper understanding of a teachers' profession and to get knowledge of how earlier experiences can influence you as a teacher. I have interviewed a female teacher, Pia to get this understanding. As a tool to get the teacher's whole story I used the life story method. In her profession she is influenced by her own importance of security as a child.Her own needs of security has given her an deeper understanding for pupils like herself during the childhood; insecure and afraid. Her understanding for all kinds of behavior among the children has increased by her own experiences.The story shows that Pia is frustrated by the fact that she can't control her own working time.

Omloppstid för returenheter

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

Energikartläggning och energieffektiviseringsåtgärder i Zoologen på Göteborgs Universitet

The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated to the building sector and to reduce the total energy consumption real efforts need to be made to make buildings more energy efficient.The aim of this study was to investigate how energy is used in one of Göteborg University?s buildings and to find measures that can be taken to improve its energy efficiency. The chosen building Zoologen, is used for research and education.The main method of the study is computer simulations of the present building and of possible energy reducing measures to be made in the future.

Vardagslyx

Our purpose with this research has been to obtain a deeper insight and understanding for the phenomenon and term ?weekday-luxury.?Through our research, we have found a link between value, service, brands and consumer behaviour into a relationship that we termed ?weekday-luxury.? This link of values is particularly interesting to us and we are curious about the underlying motivation to ?weekday-luxury? and the driving forces underlying the phenomenon. We have noticed in society that people need something extra in their daily lives and we attempt to speculate where their perceived value lies through the concept of ?weekday-luxury." Our goal is to determine a deeper understanding and insight into this phenomenon and how it meets our needs through an identifiable pattern. We also analyze the nature of ?weekday-luxury? and its meaning.

Deriving ECA-rules from timed-automata specifications.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Det Otidsenliga : Om tid och tänkande hos Gilles Deleuze

Through the notions of the untimely (l'intempestif) and untimeliness (intempestif) this paper seeks to gain a better understanding of the problematic surrounding and determining the concept of time in Deleuze. By tracing Deleuze's development of the concept of the untimely through Nietzsche and Kant, we are allowed to concretize the concept of time as pertaining to an experience of modernity (modern life), thus enabling us to better determine the place it holds within the philosophy of Deleuze itself - as a constitutive and productive problematic relating directly to the activity of thinking and being philosophically..

Tidsstudier i kalvuppfödning :

Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf. To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.

Analys av monteringslinan för luftbehandlingsaggregat (EC)

The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping. The work is going to answer the questions about today?s throughput time, how much waste that occurs, number of staff at the assembly line, how the supply of material works and possible improvements that can be made at the work stations. The work is also going to give a proposal of improve-ments that can be made.The methods used to get the result include observations and measurements, con-versations with technicians and operators and also data from Fläkt Woods? data-base.Large variations in throughput time are measured during the measure period, from 3 hours up to 5 hours and 35 minutes.
