Automatiserad konstruktion av analoga förstärkare

The last few decades the development in the field of electronics has been huge. The components performance gets better at the same time as the manufacturing cost decreases. Many of the design moments that have to be done, are done automatically today, but it can get better. Especially for analog circuit design.At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the components (transistors, resistances, capacitances etc), so that the circuit can fulfill the performance requirements.

The effect of rapeseed oil and palm oil supplement and milking frequency on milk yield and milk fat quality

Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

Planering & produktionsstyrning : Lean filosofin vid produktion av asfalt

Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.

?Daddy?, from Vision to Video

?A designer rarely works alone?. The first sentence of Jonas Löwgren and Erik Stolterman's chapter on design as a social process made me curious. What if a designer worked alone? What are the actual differences between working on a project alone and as part of a group? How would it influence the creative process? What would be different when coming up with ideas, meeting with clients and setting deadlines? Does the influence of another designer stifle the individual creativity or does it actually nurish it? This paper is written to answer these and other questions as well as take you through the creative process of the production of ?Daddy? - the music video..

?Den stora förändringen?. En mönsterkollektion höst/vinter 2013

The big change is a project where I created patterns on fabric. It is a collaborative project with Lotta Niemi. She studied fashion and textile designers and tailors from the Swedish School of Textiles in Borås and University of Technology in Sydney. The collaboration was to create designs on fabric for her upcoming clothing line for women, Fall / Winter 2013. The clothes will be sold online, in stores in Sweden and Japan.For Lotta Niemi?s clothing line, I wanted to create exclusive designs, rich patterns that worked out handmade and digital.

Pedagogisk dokumentation : begränsningar och digitala möjligheter

AbstractFörfattare: Margareta Lööf och Annika JönssonTitel: Pedagogisk dokumentation ? begränsningar och digitala möjligheterEngelsk titel: Pedagogical documentation ? limitations and digital possibilitiesAntal sidor: 28Syftet med detta examensarbete är att via kvalitativa intervjuer med öppna frågor, undersöka hur pedagoger i förskolan har förstått att den pedagogiska dokumentationen ska genomföras, hur man ställer sig till den och vad man anser krävs för att den ska bli en mer naturlig del av den dagliga verksamheten i förskolan. Utöver dessa frågor kommer arbetet även att innehålla pedagogers tankar om att använda sig av digitala verktyg i den pedagogiska dokumentationen.Nya och förändrade krav på att det ska finnas systematisk dokumentation i förskolan gör att det nu är många som anser sig arbeta med arbetsverktyget pedagogisk dokumentation. Om man inte fullt ut förstått tankarna bakom den Reggio-Emilia inspirerade pedagogiska dokumentationen, finns det en risk att dokumentationen i allt för stor grad lägger fokus på enskilda barns lärande och utveckling, utan att detta sätts i relation till den verksamhet som erbjuds. Det finns då en risk att bedömning av barn i förskolan ökar, vilket går helt emot läroplanens intentioner.

Bakhjulsupphängning, fyrhjuling

Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.

Level-Up! : En uppsats om spelutvecklares väg till ökad autonomi

Vår uppsats fokuserar på data- och tvspelsbranschen med en inriktning på relationerna mellan spelutvecklare och spelutgivare. Bakgrunden till uppsatsen och studien bygger på att maktbalansen mellan spelutvecklare och spelutgivaren faller i favör för spelutgivaren som ofta kontrollerar både finansiering och distribution av en spelproduktion. Detta skapar en situation där spelutvecklaren, som står för den skapande delen av en spelproduktion, har liten till ingen kontroll över sin egen verksamhet. Denna balans håller på att förändras genom uppkomsten av nya finansierings- och distributionsalternativ som tillåter spelutvecklaren att förbigå spelutgivarens inblandning i spelproduktionen. I vår uppsats har vi valt att undersöka hur folkfinansiering, digital distribution och mun till mun-marknadsföring påverkar spelutvecklares autonomi.

Hållbar design för en bättre värld -med hemlösa i fokus

The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.

Honung och biodling : honungens ursprung, egenskaper och effekter på människans hälsa

This report describes honey, its origin, properties and effects on human health. Honey has been used for a long time in most civilizations and apiculture is an important activity sector in many parts of the world. The trend is an increase in honey production but a decrease in the number of beekeepers in Sweden. Honeybees live in a highly developed society with a strong hierarchy and a well organized distribution of the tasks. They visit a broad spectrum of plants and collect nectar to store it as honey.

Dagens Agora : En kritisk granskning av Internets möjligheter och begränsningar

The time we live in now is significant for its many ways of spreading information- it is indeed the era of communication. The Internet is the main reason for this evolution, where you can reach out to any corner in the world in less then a second. Information is flowing over us and we get more and more used to being in a constant accessible state. The individual might spread his own word as he wishes. From a democratic point of view this should give a great opening for everyone into the public spheer.
