Effektivisering av kvävereduktionen i en konstruerad våtmark avsedd att behandla avloppsvatten
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Inlärning i Emotional Behavior Networks : Online Unsupervised Reinforcement Learning i kontinuerliga domäner
The largest project at the AICG lab at Linköping University, Cognitive models for virtual characters, focuses on creating an agent architecture for intelligent, virtual characters. The goal is to create an agent that acts naturally and gives a realistic user experience. The purpose of this thesis is to develop and implement an appropriate learning model that fits the existing agent architecture using an agile project methodology. The model developed can be seen as an online unsupervised reinforcement learning model that enhances experiences through reward. The model is based on Maes model where new effects are created depending on whether the agent is fulfilling its goals or not.The model we have developed is based on constant monitoring of the system.
Interaktiv arbetsbeskrivning
Under framtagandet av nya produkter måste ett antal prototyper tillverkas för
att verifiera konstruktionen. För en metodingenjör som tar fram
reparationsmetoder
innebär prototyptillverkning att tankar som växt fram under utvecklingsfasen
kan provas för första gången på en fysisk produkt. Detta sker relativt sent i
produktutvecklingen och eventuella ändringar som kan uppstå på grund av att
servicevänlighet inte uppnås blir mycket kostsamma. Om däremot prototypen
där metoderna verifieras för första gången är digital och detta sker tidigt
blir kostnaderna för eventuella ändringar avsevärt mycket mindre. Modellen som
ligger till grund för metodstudierna kan sedan används för att skapa ett utkast
till service litteratur, detta medför att även den delen av slutprodukten
kommer att
vara i fas med övriga utvecklings avdelningar.
Under detta projekt har en digital prototyp av en Scania motor använts för
genomförandet av metodstudier.
Fallföretaget X - Ett grönt företag i tiden
The textile business is one of the oldest industries of our time, and it employs nearly 1.4 million workers within the European Union alone. It is not unusual that this is the foundation of a country?s industrialisation. Even though the industry brings many positive factors, there are also negative factors that will influence the industry?s growth in the future.
Apputveckling : En studie av motsättningar mellan design- och användningspraktiker ur ett verksamhetsteoretiskt perspektiv
We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

Hur påverkar bävern skogens värden?
The activities of beavers in forested landscapes affect both ecological and economical values. The creation of the dynamic wetland mosaic associated to beaver activities can even improve the quality of water and have been documented as an important landscape engineer affecting the environment for many species. The local office of Sveaskog in Skinnskatteberg is responsible for the management of large areas of the forests in the County of Västmanland. In this area one of several company?s goals are to create ten new wetlands in their own forests as a part of cooperation with the Swedish bird society and Swedish wetland association.
Det bästa av två världar: en analys av bibliotekskultur vid Malmö högskola
The study of culture is specifically relevant to libraries confronting changes. A variety of conditions makes it beneficial for libraries to understand the strengths as well as the weaknesses of the underlying culture. Such an understanding can help libraries in adjusting to changes easier, without losing the cultural values that they hold important to their identity and strategic strengths.Taking this as a starting point the purpose of this essay is to examine and describe what aspects in prevailing library cultures are important to pay attention to when meeting changes. To accomplish this we will explore the concept of library culture, its substance, meaning and expression.Culture is reflected in the artifacts, values and underlying assumptions of formal and informal groups. Culture can be found at various levels.

Titel: Human being and Christian ? creationtheology of Gustaf Wingren.Analysis of an accentshift from a juridical theological metaphor to a biological theological metaphor.Author: Tove Pilroth.The purpose of the essay is to analyse the meaning and the consequences, in a critical and constructive way, of an accentshift of interpretation and understanding of the gospel, from a juridical theological metaphor to a biological theological metaphor. The purpose is presented in the frame of the creationtheology of Wingren. To be able to make the research and to answer the purpose of the essay, the following questions are essential:The human being is captive and redemption is liberation. If we are serious about that the gospel gives the human being rehabilitation, satisfaction, liberation and a life and a future with God, the essential question is which metaphor, a juridical or a biological, that speaks to the human being in the best way? What is the meaning of an accentshift from a juridical to a biological metaphor? How does the creationtheologhy of Wingren, from a biological metaphor, meets the situation of the existence for the human being, her longing for life, health and meaning? What kind of theological resources are present in the creationtheology of Wingren, in the confrontation with future theological challenges?The essay is stressing the need of pluralism in the interpretation of the gospel.

This report presents a thesis project conducted by two students at Mälardalens högskola. The project covers 15 points in industrial design and was conducted during April to June 2014. The principal of the thesis works at Plastic Produkter. The assignment was to develop equipment for an effective way to dose, mix silicon, fill a special designed plastic bag and then seal it. The bag is then formed into a breast model.When a customer for various reasons decides to do a breast augmentation or a breast reconstruction, there may be doubt or uncertainty about the result.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.
Energiåtgång och Kostnad för Interna Transporter
Detta examensarbete är genomfört åt Sandvik Mining and Construction inom ramen för det statliga samarbetsprojektet MinBaS II. Sandvik Mining and Construction är ett av Sandvik koncernens affärsområden och har en världsledande position på marknaden för maskiner och tekniska lösningar för bergbrytning m.mMinBas II är ett samarbetsprojekt mellan ett stort antal företag och universitet där staten står som huvudman och löper till 2010.Uppgiften med examensarbetet var att se om det fanns någon metod för att kartlägga de interna transporterna och beräkna deras energiåtgång i en bergtäckt. I brist på en befintlig skulle det tas fram en ny metod och sedan testa denna genom att genomföra fältstudier i en bergtäkt tillhörande Skånska Makadam AB för att sedan göra beräkningar på energiåtgången där.Volvo CE har under arbetet ställt upp med information och även givit oss SiteSimulation, ett simuleringsprogram för simulering av användning av deras maskiner.En del av arbetet var också att utreda hur energiåtgången ändras om förkrossen placeras på en högre respektive lägre nivå än det ställe där bergbrytningen genomförs.För att införskaffa underlag till beräkningarna har fältstudier genomförts i Skånska Makadam AB:s bergtäkt. Där gjordes bl.a. uppmätningar av den fysiska miljön som t.ex.
