Tradingmodeller för valutamarknaden
Syftet med denna uppsats är att testa olika tradingmodeller inom valutahandel, byggda på tekniska indikatorer, för att undersöka om man kan nå en positiv avkastning.Undersökningen omfattar 24 olika modeller, byggda på fyra olika tekniska indikatorer och med tre olika money management strategier. Modellerna testas på fem olika valutapar under tre månaders tid. Slutsatsen är att det går att nå positiv avkastning och även positiv överavkastning med automatiska tradingmodeller om rätt indikatorer och money management strategier används. Modellernas avkastning är mer känsliga för valet av money management strategi än för valet av vilka tekniska indikatorer och parametervärden som ska användas..
Crisis Management ? En analys av dess innebörd i ett svenskt företag
Syftet med uppsatsen är att göra en systematisk beskrivning, utifrån ett aktörs- och aktivitetsperspektiv, av ämnet Crisis Management. Detta för att skapa ett djup och en förståelse kring begreppet Crisis Management och dess innebörd i ett svenskt företag. Vi har för avsikt att först utföra en teoristudie för att sedan kunna jämföra denna med praktiken, för att erhålla den bas som behövs för att diskutera och besvara vår problemformulering. Resultatet av ett effektivt Crisis Management blir enligt oss, att Crisis Mangement utgör en psykologisk effekt på företag och dess aktörer. Den trygghetskänsla, vilken Crisis Management genererar, föder en säkerhet hos företag.
Temperaturzoner för lagring av värmeenergi i cirkulärt borrhålsfält
The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.
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.
Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie
The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..
Värdet av att bygga grönt för kommunala bostadsbolag
AbstractThe real estate sector is today responsible for 40 per cent of the total amount of energy consumption within the members of the EU. All over the world there are collaborations within research and projects to find ways of reducing the amount of energy consumed by the real estate sector. In Sweden, a directive from the European Union has posed demands on authorities as well as on the private sector to reduce the amount of energy consumed by new building constructions. Together with the directive from the EU there are also new requirements and demands from Boverket for the real estate sector. These requirements mostly concern the energy consumption of kilowatt-hour per square metre and that the consumed energy also should be renewable. The aim of this study is to explain what kind of value municipalities experience in using certifications and environmental investments for new and existing buildings. Within the chapter theory, essential areas are described such as; environmental certification systems, economical viability, proceeds connected to building green, difficulties with building green, the performance of green buildings when affected by the behaviour of tenants and customer value. The following chapter describes the methodology with which we have conducted this study.

Miljöstyrning i Riksbyggens ombyggnadsprocess med hjälp av Miljöbyggnad
How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses.
Norra Djurga?rdsstaden som nollstad : En studie av miljo?projektets sista etapp och dess potential
All around the world more and more people move from rural areas to live in the cities. Because of this, the urban areas have become an important part in the debate about the effects on the environment and sustainability. In many countries word wide initiatives have been taken to build sustainable cities and eco cities, the Stockholm Royal Seaport is one example. The vision for the district is to become a world class sustainable city based on the three dimensions of sustainable development: social, economic and ecologic. The municipality of Stockholm has set requirements for the buildings? energy usage, emissions and amount of waste generated during the building process.
Performance Management i E-handel
Too much attention has been given to mainstream approaches in performance management and management accounting research, without taking in to account changes in the environment with the rapid growth of online retailing. This paper evaluates how and/or if performance management differs in online contexts by using a conceptual model developed by Ferreira et al (2009). The model and its components are tested on three multichannel- and six e-commerce businesses. The result and its analysis is commented on by two e - commerce experts. The result shows that the operation method of the models twelve components do not differ in terms of work methods in online and offline contexts.

Äldreomsorgen och de sju små doktrinerna: En empirisk studie av New Public Management-reformer inom svensk äldreomsorg
The purpose of this paper is to perform an in-depth analysis of how New Public Management reforms have impacted management practises in two publicly financed elderly care providers in Sweden. The paper studies one public and one private elderly care provider and analyses to what extent they have implemented New Public Management methods. The results are based on interviews with several persons within the two organisations and analysed using the seven New Public Management doctrines as described by Christopher Hood (1991; 1995). The major finding in the thesis is that the level of exposure towards New Public Management reforms differs between the two studied organisations where the private provider is exposed to the reforms to a greater extent than the public. The paper concludes that the main reasons for the low extent of exposure in the public provider could be attributed to the lack of measurable standards performance as well as the proximity to the political leadership..
Filosofi, kultur och management i Folkrepubliken Kina - En studie av kopplingen mellan filosofi och praktik
In order to get full understanding of management culture and practice one must understand the underlying factors. This thesis examines the philosophical foundations for management in the People's Republic of China with its primary focus on the period 1949 -2012. China with its strong economic development in the recent decades is becoming an increasingly important actor in the world economy. Interaction between China and the rest of the word is considerable and currently Chinese firms increasingly expand outside China. This gives further importance especially for westerners to gain a deeper understanding of Chinese views and customs with regard to management.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.
