Optimerade material för optiska komponenter i koncentrerande solfångare

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

Sustainable business practices : a review of eco-efficiency

The current demanding business environment requires corporations to act fast in finding effective solutions to problems given the myriad of challenges they face (Dyllick & Hockerts, 2001). The challenges include the impact of climate change on business practices, natural resource consumption, chemical pollution, technological change etc. Moreover, the forces of globalization, heightened concerns about the deteriorating quality of the physical environment and increased stakeholder power are also increasingly having a real influence on business practices (Rainey, 2008). Since 1992, the World Business Council for Sustainable Development (WBCSD) has encouraged the adoption of the concept of ecological efficiency (eco-efficiency) to support business efforts aimed at addressing some of these challenges. The aim of eco-efficiency is to reduce the amount of energy and materials used in production processes to achieve economic and environmental benefits (WBCSD, 2000).

Hur enkel- & dubbelportsturbin i kombination med två olika avgassamlare påverkar gasväxlingsprestanda på en Scania V8

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

Return Behavior of Initial Public Offerings and Market Efficiency

This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.

In order to continue to be competitive in the current industrial climate, producers must increase efficiency at their plants. Several Swedish companies choose to utilise the principles of Lean production. Tour & Andersson AB (TA) has elected to create their own model using Toyota?s productions system which has been named TAPS (Tour & Andersson Production System). Following two years of working with TAPS the company has decided to introduce Total Productive Maintenance (TPM). Most of the work carried out in the maintenance department today is in form of repairs to already faulty equipment.

Lönsam energieffektivisering : En beskrivning av energieffektiva åtgärder i flerbostadshus och dess lönsamhet

Environmental impact and management of energy is a highly topical issue in today's society. Climate impact must be reduced. The Government has set a target to reduce energy consumption in buildings by 20 % by 2020 and 50 % by 2050 compared to the energy use in 1995.With this in mind, we chose to examine how property owners can work on improving energy efficiency in existing apartment buildings. We also wanted to investigate profitability of different increasing energy efficiency measures and the calculation methods and the risk assessment performed by such investments. To tie in with government objectives, we also saw the possibilities of achieving these goals.20 companies were interviewed, of which 14 were property owners and 6 were consulting firms that works with energy efficiency.

Till  framtida utvecklare

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Effektivitet som ett mål vid decentralisering, finns den? : Om samverkan och decentralisering i Kalmar kommun för en bättre arbetsmarknadsetablering av invandrare.

This essay will explain the effects of decentralisation, and what impact it has on the efficiency to create a better integration for immigrants on the Swedish labour market. Examples of literature that has been examined are Marcus Gossas and Jon Pierre. From these authors, I have been trying to explain the relationship between decentralisation, cooperation and efficiency.Since the end of the Second World War until the middle of 1980, Sweden mostly received labour immigrant. Since then, the immigrant pattern has changed to consist of mostly refugees. Changed immigration patterns together with increasing debts for the Swedish government has lead to decentralisation and cooperation between public authorities has therefore become a target to reach better efficiency.

Möjligheter till ökat utnyttjande av fosfor genom grödan med mineralgödselmedel

The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

Smartphones på arbetsplatsen : En studie av smartphones påverkan på effektivitet och välmående bland yrkesverksamma människor

In todays society IT in general and the Internet in particular are given elements in people´s everyday lives, and smartphones has come to be a big part of those elements. This study focuses on how the use of Smartphones in particular influences the individuals in their working environment, and how this use influence the efficiency and the well-being of said individuals.  To answer our research question regarding how said use comes to effect the efficiency and the well-being for proffesionals in their working environment we have used data from qualitative interviews who is enriched by a short initial diary study. This data has then been analyzed using the Affinity Diagrams Technique, leading to four central themes emerging from the data. The results show that smartphone use at work comes with both positive and negative effects; efficiency increased through the use of smartphones due to the great versatility that comes with the technology, while in terms of well-being issues of stress emerged.
