Är företagets lönsamhet och finansiella ställning avgörande för beslut beträffande företagets expansion?

Even if the main purpose is to decide if the companies profitability and financial position is a determining factor for its growth, the purpose is to determine if there are any differences between big and small companies in there economical positions then they grow, in the selected industry. This thesis is mainly a quantitative study. The selected industry for the study is extraction of turf. The financial measurement that most clearly differ the growing companies from the not growing companies or the companies that didn?t change there amount of employees was the returns of the companies own capital. It was also the returns of the companies own capital there the main difference existed between the big and the small companies.

Det Intelligenta Huset : - En studie i hemautomation

Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

Internet of Things & Kommunikationsprotokoll

Genom att studera olika kommunikationsprotokoll kunna svara på vad det är som gör att ett visst protokoll är bäst anpassat för att användas mellan mobila enheter och IoT-enheter.I arbetet användes en kvalitativ litteraturstudie för att ge en grundlig teoretisk bakgrund samt en experimentell studie där ett par teorier undersökts ifall de stämmer med resultaten ifrån verkligheten. De fem faktorerna kompatibilitet, batteritid, frekvens, räckvidd och tillförlitlighet undersöktes hos kommunikationsprotokollen Bluetooth Low Energy (BLE), Närfältskommunikation (NFC) och Wi-Fi. Dessa tre valdes eftersom de stöds av nyare mobila plattformar idag. Kommunikations-protokollen analyserades sedan gentemot olika användningsområden inom IoT, eftersom påståendet vad som är bäst anpassat beror på vad situationen kräver för egenskaper.En systemutvecklare som ska välja kommunikationsprotokoll till en IoT-tillämpning och läser denna rapport bör själv jämföra de olika protokollen mot varandra inom de fem faktorerna för att kunna avgöra vilket protokoll som passar bäst inom dennes situation. I arbetet utfördes endast experimentella studier på BLE på grund av begränsningar inom utrustningen.

Nitrogen flow in Scania : substance flow analysis on a regional level

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

Finansiell företagsvärdering med uppskattning av humankapital : En studie av värderingen på den svenska marknaden

The importance of human capital in firm valuation is something Huang and Wang points out in there paper from 2008. We expand Ohlson?s valuation model (1995) in line with Huang and Wang (2008) to enhance a market value that includes proxies for human capital. By using human capital based market value and one of Francis, Nanda and Olsson?s (2008) version of earnings quality, we create a value table which aim to sort for undervalued and overvalued companies during the  economic upswing of 2003 to 2007 in the human capital line of business.

Marknadsföring via sociala medier : Vilka marknadsföringsmöjligheter ger sociala medier för småföretag inom turism- och upplevelseindustrin?

This paper intends to show how micro- and small businesses in the tourism and experience industry makes use of social media as a marketing tool. The study also shows the possibilities for businesses to market themselves to customers through social media. Small businesses usually don?t have the same conditions or the same marketing resources that larger companies have. For small businesses that lack marketing resources, social media is a great addition to marketing since the technology around social media is relatively simple.

The Capital Structure Puzzle of SME's - Evidence from the Swedish Security Industry

The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..

Utredning av solenergi för drivning av sorptiv kylprocess för inomhusluften på Stockholmsarenan

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

Ökad resurseffektivitet i kraftvärmesystem genom säsongslagring av värme

Increased resource efficiency in an energy system could result in large economic and environmental benefits. Tekniska verken i Linköping AB (Tekniska verken) is responsible for the district heating network in Linköping. Their vision is to create the world?s most resource efficient region. An important step towards this vision is more efficient usage of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system.

Kommunicera mera! En kvantitativ studie om begreppet CSR och effekter av CSR-kommunikation på konsumenter inom konfektionsindustrin.

Companies in the apparel industry are becoming increasingly responsible with regards to the social and environmental issues related to textile production. Despite these tendencies, there are great insecurities surrounding the concept of CSR and the effects on consumers of CSR communication. There is currently no model for breaking the concept of CSR down into smaller elements, specific for the apparel industry. In the first part of this thesis, we create such a model, applicable in a consumer communication context. In the second part, we investigate the effects on consumer attitudes and intentions of communicating the different elements of CSR presented in the model.

Riskkapitalinvesteringar i svensk miljöteknik - obalans mellan utbudet och efterfrågan?

Earth?s resources have been exploited unsustainably. If an entire conception of exploitationof natural resources does not change now, this will entail enormous costs in the future.This insight has lead to a recently increased interest in clean technologies among privateequity capitalists. In the fourth quarter of 2006 about 10 percent of all private equityinvestments made in the US market were placed in the cleantech industry. Despite a goodinvesting climate in Sweden, Swedish capitalists have shown little interest in cleantechinvestments.

Jämförande simulering och modellering av framtida järnvägars elenergiförsörjning

In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.

Materiallogistik vid innerstadsprojekt : En fallstudie av ett innerstadsprojekt i förbättringssyfte av materialflödet

The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.

The purpose of this thesis was to investigate the need of working instructions in Derome Träteknik ?s industrial house-building factories. Furthermore we wanted to determine an appropriate way for developing working instructions adapted to the conditions in a certain production environment. In the construction industry today prefabricated building elements are frequently used. With this come repetitive work tasks that need to be carefully planned.

Preparering av kabelände inför statorlindning

At Uppsala university scientists have during the last years developed and built wave energy converters. This project is called "Lysekilsprojektet". The development has come so far that they are currently investigating how to gain profit in a mass production. For that reason they want to automate as many steps in the production as possible.The winding of the stator is one part that is being automated using industry robots. The stator is cable wound unlike many other generators.
