This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.

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.

Brädde, L & Ramstorp, C (2013). Öppna frågor i geometri i ett specialpedagogiskt perspektiv (Open-ended questions in geometry within special pedagogic perspective). Speciallärarexamen 90hp matematikutveckling, Skolutveckling och ledarskap, Lärande och samhälle, Malmö högskola. Problemområde Både internationella och nationella undersökningar visar att elevernas matematikkunskaper har försämrats. Ahlberg (1995; 2001) anser att flertalet forskare är eniga om att elevernas problemlösningsförmåga måste utvecklas. Vi blev inspirerade av de positiva effekter som Ingmar Holgersson från högskolan i Kristianstad framförde (18/2 2012) om öppna frågor i matematik.

Införande av nya innovationer och utmönstring av äldre teknologier inom hälso- och sjukvården är inte helt okomplicerad. Ett flertal omständigheter och problem måste beaktas, exempelvis att ökad tillgång till bättre teknologi och tillämpning av ny kunskap visserligen ger förbättrad hälsa, men utvecklingen och användningen av ny medicinsk teknologi innebär även ökade hälso- och sjukvårdskostnader. Hälso- och sjukvården måste därför kunna balansera de tre målen kostnadseffektivitet, kostnadskontroll och främja utvecklingen av innovationer. Det är fakta som tas upp redan i inledning och bakgrund och områdena behandlas framåt i uppsatsen. Syftet med den här uppsatsen är därför att beskriva och analysera införandet av nya innovationer och utmönstringen av äldre teknologier inom hälso- och sjukvården.
