Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

Wooden joist slabs is a common type of floor in residential buildings. Higher demand and production of residential buildings increases the possibilities of profiting by optimizing the system of joists in a variety of areas. Spring and deflection is something most people can relate to since it?s not that uncommon to hear furniture rattle when you walk over a wooden floor. To remove the presence of those kinds of vibrations the system of joists have to be made stiffer than the standard joist construction that is used in today?s constructions.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.
Utveckling av en ny tillverkningslina
This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.
Hur pratar lärare om konkret material i matematiken?
Då jag varit ute på praktik har jag sett att elever allt för ofta bara sitter och räknar i läroboken. Vi matematiklärare måste bli bättre på att variera och börja laborera i vår undervisning. Både för att få med eleverna kunskapsmässigt i undervisningen och för att få dem intresserade och engagerade. Jag har därför i mitt examensarbete undersökt om lärare i år 4-6 använder sig utav konkret material i sin matematikundervisning. Mina problemformuleringar var:- Vad använder lärare i år 4-6 för konkreta material i sin matematikundervisning?- Hur gör lärare i år 4-6 för att konkretisera matematikundervisningen?- Varför väljer de som konkretiserar matematikundervisningen att konkretisera?Metoder som jag använt i min undersökning är litteraturstudier och intervjuer.
Perspektiv på genusidentitet i förhistorien : Så resonerar forskarna
This essay examines how four archaeology scholars reason about gender. I have used a qualitative method in making this study of their dissertations. The aim is to obtain a deeper understanding of gender identity in prehistory, gaining a broader appreciation of how this might be expressed through archaeological material. This essay takes its theoretical departure from postprocessual thinking, where gender perspectives, including feminist and queer theories are in focus. The result of this study shows that the scholars have a postprocessual, structuralistic theoretical perspective in common, and that they use stereotypical identity-descriptions.

Is goat milk a better milk replacement to piglets, rat pups and foals than cow milk is?
AbstractOne opinion among people who are experienced in hand rearing newborn mammals is that goat milk is more suitable than cow milk if the young needs a milk replacer. The purpose of this literature review was to find out if there is scientific evidence that goat milk is a better milk replacer for piglets, rat pups and foals than cow milk. The milk is essential for the newborn animal, as its only source of nutrition until it has learned how to eat solid food. In this literature review, the composition of goat milk and cow milk is compared with the nutrient requirements after birth in piglets, rat pups and foals. The nutrient requirements and the milk composition are partly determined by the newborn mammals activity level and suckling frequency, which also is described.
CSRD och det offentliga : En analys av svenska kommuners anammande av CSRD
The European Union's Corporate Sustainability Reporting Directive (CSRD) aims toenhance and standardize sustainability reporting to support the green transition. While the public sector is expected to lead in sustainability, the application of CSRD within Swedish municipalities is fragmented. Many municipally owned companies fall below reporting thresholds individually, creating a transparency gap despite the municipal group often exceeding these thresholds collectively. This discrepancy raises moral and strategic questions regarding public accountability and the effective utilization of the framework. This thesis investigates the rationale for the proactive adoption of CSRD principles bySwedish municipalities, irrespective of formal legal requirements.
Prisvolatiliteten på återvunnet material: En studie av prisvolatilitetens historiska förändring på marknaden för återvunnet material
Tidigare forskning visar på att en prisvolatilitet existerar på marknaden för återvunnet material och att den många gånger är högre än volatiliteten för dess motsvarande jungfruliga material. Prisvolatilitet på marknaden för återvunnet material verkar vara en av orsakerna till osäkerhet på marknaden vilket i sin tur hämmar investeringar i marknaden, vilket leder till att färre substituerar jungfrulig råvara mot återvunnen råvara. Volatiliteten på återvunnet material kan ses från två olika perspektiv, ett där volatilitet är en orsak av effektiva marknader som styrs av utbud och efterfrågan och ett där volatilitet är en orsak av olika marknadsmisslyckanden. Syftet med denna studie är att mäta förändringen i volatiliteten för återvunnet material, utifrån ett antagande om att volatiliteten minskar över tiden då marknaderna för återvunnet material mognar och blir mer etablerade. Standardavvikelse används som mått för att mäta volatiliteten, där volatiliteten mäts för fem olika material, vilka har olika tidsperioder beroende på material.
Alternativa förpackningsmaterial och konstruktioner för »Hackman tools«-serien
Choosing a new plastic material for a container includes several different steps. In this case,the Finnish company Hackman needed a new type of packaging material for theircutlery- and kitchentool series »Hackman tools«. The project was carried out in cooperationwith the design agency Ytterborn & Fuentes, which has Hackman as a client.Several different demands were put on the material in order to fulfill as many of the clientswishes as possible. The most urgent problem with the existing container was the difficultysfor the customer to clearly see the contents in the container. Because of this problemthe customer tried to open the container in the shop.
Electrolux och patenten. En studie av Electrolux patentstrategiska agerande 1950-1970.
Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.
