Arsenikförorenad mark efter träimpregnering : fastläggning, spridning och efterbehandling
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.

Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
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.
The vertical farm : varför har idén uppkommit och hur är den tänkt att fungera?
By immersion in the situation of the food production today and a historical study of how past development has led us to this point, one goal of this essay is to discuss whether the current way of farming can be applied in a sustainable future. Another objective of the essay is to study the vision Vertical farming as an alternative approach, and to focus on different aspects of this phenomenon in order to provide as comprehensive a picture as possible.The paper, thus, seeks to broaden the views for alternative approaches regarding a well-established method which we often take for granted. The aim is also to initiate a discussion around the need to also take radical ideas in regard if we want to face the future in a sustainable manner. The method is a qualitative literary study where scientific articles and papers have been used to discuss the issues: why has the idea of Vertical farming arisen, what is Vertical farming and how is the Vertical Farm meant to operate? Does Vertical farming have a place in the sustainable city of the future? For a long time us humans lived as one with nature, in a symbiotic relationship in which we gave and took as a functioning part of an ecosystem.
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.
Tre lampor och ett ben : produktserie för Gotlands Lampfabrik
Gotlands Lampfabrik är en nystartad verksamhet (2009) som drivs av Jonas Kling och Jane Odell centralt på Gotland. De producerar stilrena lampskärmar i ett ljust polymermaterial med papp på båda sidorna.Produktionen är liten och görs för hand på plats i den egna fabriken i Väskinde.Sortimentet består av 33 lampskärmar och i nuläget producerar inte Gotlands Lampfabrik sina egna lampben eller upphängningar utan köper in dem från fristående parter vilket medför att sortimentet kan uppfattas som spretigt och osammanhängande. Dagens sortiment saknar även vägglampor och ljuskällorna som används är glödlampor som från och med 2009 håller på att urfasas från den Europeiska marknaden efter ett beslut från EU. Möjligheten att kunna välja lampor från samma serie till sitt hem är både efterfrågat samt kan ge en känsla av sammanhållen och genomtänkt interiör. Genom att göra en produktserie med tillhörande upphängning samt lampben skulle verksamheten kunna profilera sig bättre och få en mer tydlig produktidentitet.I ett nära samarbete med Jonas på Gotlands Lampfabrik kom vi gemensamt överens om att skapa en ny produktserie med tydligt släktskap till varandra.
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.

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.

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.
