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.
Albys skärvor : Lipid- och morfologisk analys av tidigneolitisk keramik från Öland
In this essay, Neolithic potsherds from Alby, Öland has been examined. The purpose was to investigate the connection between the lipid residues and the vessel shapes and ornament. To solve the attempt lipid and morphological analyses were executed. The lipid analysis revealed traces of different food residues and the morphological method showed various shapes and decors. The result indicates that the Alby ceramics has been used for cooking/storage of different fish and meat dishes, as well as vegetables and that the vegetables doesn?t derive of cereals..
Utveckling och tillämpning av en GIS-baserad hydrologisk modell
A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.
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.
Färsk ved till Hallstaviks pappersbruk :
Hallstaviks papermill is an industry plant within Holmen Paper. Hallstavik is a mechanical
mill and produce newspaper and journal paper. During year 2000, Hallstavik used
approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the
production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.
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.
Några svenskars fritid- En strike för det sociala kapitalet?
The title of this study came about from the title of Robert Putnams book Bowling Alone, where Putnam mentions that less people are bowling in teams than before. Bowling is still a large leisure activity in the USA but people tend to bowl more and more in small groups and less in organized teams. This study deals with social capital and leisure time. Its aim is to find out if some Swedish people create social capital on their leisure time and also how do they spend their leisure time. Robert Putnams book Bowling Alone serves as main background material along with the work by Bo Rothstein.
Analys och reducering av kapitalbindning i lager : Analysis and reduction of capital tied to existing stock
Detta arbete genomfördes under 10 veckor vårterminen 2009 på Bigso Box AB i Nybro,ett företag som tillverkar förvaringslösningar för hemmet och har stora kunder somIKEA.Bigso vill ha hjälp med att undersöka materialflödet och de lagernivåer företaget besitteri sin producerande fabrik i Litauen. Främsta målet med arbetet var att minskakapitalbindning i färdiga produkter samt på halvfabrikat i fabriken. Då Bigsos störstakund IKEA ställer extremt höga krav på leveranstider och företaget ibland hamnar eftermed ordrar önskar Bigso även att genom en större kontroll av materialflödet och genomatt hålla rätt lagernivåer även komma till rätta med detta problem..
Tidspress och ekonomiskt risktagande
Stress and time pressure is more present in todays labor markets. In financial markets a securities broker is forced to take decisions on investments under high cognitive load and under extreme time pressure. The research of decision under risk gained new ground with the development of the prospect theory and gave us new insights to the decision making of men. Prospect theory has shown that people are risk seekers when dealing with loss decisions and risk avert when dealing with profit decisions. The value function are defined over gains and losses.
Dammsugare att motivera till dammsugning
How can a vacuum cleaner motivate you to use it? From a sustainability perspective,the author asked the question of how such a solution would looklike? These where issues that the project tackled and devised solutions for. Theproject wanted to explore the physical modeling and a large part of the finalresult consisted of a full scale model. The project found that the problem ofvacuuming largely consisted of the problem of storage the product. The projectfound that the motivation for the job, therefore, could be resolved by a betterdesigned vacuum cleaner with a built-in hose, folding handles, which couldbe stored integrated within the vacuum cleaner.
Följdinvandring och medborgarskap : en statistisk analys
During the last years around 100 000 immigrants have arrived to Sweden, people with different reasons and different goals for settling down in Sweden. The reason for immigrating to Sweden that will be dealt with in this thesis is following immigration, i.e. when someone moves here because they have relatives living in the country.The reason why it is interesting to study following immigration is that it is an affecting factor for how many that will immigrate to Sweden the following years and may then be used to make a forecast, based on how many first time immigrants there are. To be able to investigate the following immigration analyses are made with time series, logistic regression and Poisson regression. An ARIMA-model has been used to estimate the number of following immigrants in the future.The other part of this thesis will inquire the matter how inclined immigrants are to become Swedish citizens, whether they even apply for citizenship and also how long time it takes from the time when they fulfil the conditions for Swedish citizenship until they apply.
Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.
Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.
