How to future proof a Business Model : Capture and capitalize value in the field of Urban Mining
Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.
Kartläggning av reparationsprocessen på Westermo Teleindustri AB : Identifiering av slöserier och förslag till förbättringar
This report is the result of a thesis performed at Westermo Industrial Ltd with its headquarters in Stora Sundby and it sums up the author's studies for University Engineering in Innovation, Production and Logistics at Mälardalen University.The main goal of the thesis was to identify problems and suggest actions that lead to the reduction of the repair time from 3 weeks to 2 weeks. The key questions that were answered in order to achieve the thesis objectives are: What are the biggest challenges that make the repair process time last for 3 weeks? What are the necessary means and measures in order to reduce the repair length to 2 weeks? The author adjusted the work to the Swedish repairs, repair issues that arise from sell unit Westermo Data Communications AB with its office in Västerås and performed the status report by mapping the repair process, through using observations, interviews and bibliography research studies. A flow map of four sub-processes (Inbound Delivery, BackOffice, Repair Department, and Logistics) was made and each section was observed, where also the employees were interviewed. Data that has been collected was analysed by the author and the decision to execute a workshop that affects Repair Department and Logistics was made.
Framtagning av reläskyddsinställningar för en transformatorstation
A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.
Framtida användningsområden för materialadderande tillverkning : En studie i hur materialadderande tillverkning kan användas i rymden
In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. Our studies have shown that Additive Manufacturing has great potential for establishing colonies on not only the Moon, but perhaps even further away from our home planet. With Contour Crafting-technology in combination with ISRU (In Situ Resource Utilization) we could, with material already present in the sediment layers of the Moon, construct advanced structures without having to transfer any extra material from Earth. This would lower the costs of establishing a colony on the Moon to such extents that it could actually be fiscally possible..
Översiktlig buller- och luftföroreningsinventering i Burlövs kommun år 1994 med hjälp av geografiska informationssystem : möjligheter och begränsningar
Det är framförallt två övergripande frågor som vi har försökt besvara med denna studien: Hur är situationen vad gäller väg- och tågtrafikinducerade buller- och luftföroreningar i Burlövs Kommun 1994 och hur många av kommunens invånare påverkas av för höga halter/nivåer? Är den översiktliga metoden som vi har valt att arbeta med, i kombination med tillgänglig data, lämplig och tillräckligt exakt för att beskriva den aktuella miljösituationen i Burlövs Kommun?.
Algebra i gymnasieskolan : Vilka svårigheter har eleverna?
During my practice as a teacher trainee at an upper secondary school it became clear to me that many pupils have difficulties with algebra. Also in a report from the National Agency for Education (1999) you can see that the students algebra knowledge get worse and worse. I was surprised to find that many pupils seemed to get stuck on the level of attainment for the senior level of the nine-year compulsory school. As I have not studied anything about difficulties in algebra during my training to become a qualified teacher I would like to get to know more about this. I also examine why you have to study algebra in upper secondary school.
Gässensinverkan på näringsreduceringsdammar i Sydvästskåne - kan lokala gåsbestånd bidra till en ökning av kväve och forfor i mindre vattensamlingar.
De flesta svenska gåsbestånden har ökat kraftigt de senaste decennierna, och de stannar ofta längre i Skåne innan och under flytt än vad de tidigare gjort. Detta har lett till ett ökat tryck på landskapet, särskilt i områden där stora flockar samlas som till exempel vid vattendrag. Syftet med studien är att illustrera vikten av gässens avföring med hänsyn till näringstillförsel i jämförelse med andra lokala näringskällor. Fyra dammar inventerades mellan maj 2004 och mars 2005..
Påsköns stenstatyer, moai : Vilket genus representerar de?
Abstract.The question in this analysis is which gender moai, the big statues on Rapa Nui, represent. My hypothesis is that they have developed from visual symbols to metaphores in mythologies from an polynesian context. That these statues were symbols for human origin and creation of ancestors ideological power, and gods in consideration male gender. In the long isolation, in both time and space, the mytologies in Rapa Nui was changed, and the pictures got a new meaning. These changes depended on clearing of wood and big trees and the following difficult situation in farming.
Culhwch & Lúthien : Keltisk mytologi i J. R. R. Tolkiens sagovärld
This study investigates in what respects Celtic mythology influenced J. R. R. Tolkien when writing the sagas incorporated in the mythopoeic compilation of The Silmarillion. Through narrative and comparative analysis, stories from the Irish prose collection Lebor Gabála Érenn, as well as the Welsh medieval manuscript Mabinogion, are collated to the tales of The Silmarillion in order to illuminate possible influences.
Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder
The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..

Termohalin cirkulation i Nordatlanten
Den termohalina cirkulationen är en global havscirkulation driven av densitetsskillnader, som gör att varmt vatten transporteras mot polerna och kallt vatten mot ekvatorn. Densiteten påverkas av temperatur och salinitet (och tryck, som vanligtvis ignoreras). Därför heter cirkulationen termohalin. Saliniteten minskar när vatten tillförs genom nederbörd, havsissmältning eller landavrinning. Saliniteten ökar genom avdunstning och isbildning.
