Värdering av Speed ? Ett onoterat aktiebolag

Värdet på ett företag kan variera beroende på vilken nytta det kan anses ha för olika individer.Att finna ett värde på ett företag som är fullkomligt sant, objektivt eller obestridligt är därför iprincip en omöjlighet. Resultatet av en företagsvärdering bygger i stor utsträckning påantaganden och subjektiva uppskattningar vilket påverkar bedömningen, men även syftet ochvilken typ av företag det gäller har betydelse för värderingen.Värdering av såväl onoterade som noterade företag bygger på samma modeller och principer,men det är förknippat med större osäkerhet och svårighet att bedöma ett onoterat företag.Problematiken ligger bland annat i att det för onoterade företag saknas löpandemarknadsvärde från börsen. Dessutom är det förknippat med större svårighet att fastställadiskonteringsräntan vid användandet av en diskonteringsmodell och finna ett sannolikt måttpå risk. Problem kan även uppstå på grund av att onoterade företags värde i många fall har enstark koppling till dess ägare.Syftet med uppsatsen är att beskriva vilka delar som påverkar en värdering av ett onoterattjänsteföretag, för att därefter förklara hur ett teoretiskt förankrat värde kan fastställas. Studienomfattar bemanningsföretaget Speed Management AB och uppsatsen grundar sig på följandefrågeställningar:? Vilka delar bör beaktas vid en värdering av det onoterade företaget Speed?? Vilket värde på Speed kan slutligen uppskattas när teori förankras i empiri?Studien utgår från olika teoretiska värderingsmodeller för att påvisa arbetsgången när ettonoterat företag skall värderas.

Konsekvenser av ny teknik på en sjukhusmottagning

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

FE safety analysis of a high speed wood planer cutter. An alternative method to achieve the requirements of EN847 standard

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

Hur rör sig polisens tjänstehundar? : en pilotstudie gällande tjänstehundars rörelsesymmetri mätt med tryckmätningsmatta

SammanfattningBakgrundDet är i Sverige svårt att tillgodose behovet av cirka 450 tjänstehundar och gällande hälsa är uppfattningen bland användarna att hundarnas fysiska hållbarhet blivit sämre. Med hänsyn till att det lider brist på tjänstehundar och att de tas ur tjänst tidigare än önskat vore det av stort värde att kunna förlänga en polishunds tjänstgöringstid. Ett sätt att förverkliga detta kan vara att använda undersökningstekniker vilka tidigt kan fånga upp lindriga förändringar i rörelsesymmetri, förändringar som kan vara ett första tecken på smärta. En tryckmätningsmatta kan registrera små förändringar i hur hunden belastar sina ben, förändringar som är svåra att se med blotta ögat. Det kan därför vara av intresse att ta fram ett normalmaterial för tjänstehundar så att det med tryckmätningsmattans hjälp tidigt går att upptäcka om en stoisk tjänstehund har ett förändrat rörelsemönster.Syfte & hypotesSyftet var att använda en tryckmätningsmatta för att skapa ett normalmaterial för en tjänstehundspopulation gällande parametrar registrerade med tryckmätnings-mattan.

High speed network adapters

Syftet med examensarbetet har varit att undersöka om Mt Memotekniks produkter uppfyller ISO/IEC 11801:2 standarden, eller om de med hjälp av kondensatorer kan klara kraven för överhörningar. Vi har även jämfört deras produkter med AMP?s Keystone jack som redan klarar kraven för Cat 6 standarden. Memoteknik tillverkar en kretskortsprodukt som består av nätverksmoduler för Ethernet. Dessa kabelsystem skall uppfylla en viss standard för kategori 6.

Överföring av digital video via FireWire

Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.

Strömningen i och över en skog : utvärdering av en 'mixing-layer' hypotes

A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.

CFD-simulering av kallras från fönster : Konvektorers och nischdjupets inverkan på lufthastigheter i rummet

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

Marknadsanalys av ett svenskt transportsystem med höghastighetsgodståg.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

En kvalitativ utvärdering av det accelerometerbaserade hältdetektionssystemet ?Lameness Locator? :

Background: Evaluation of lameness in horses is traditionally performed by a veterinarian who subjectively evaluates the movements of the horse. Accordingly, lameness diagnosis varies with the veterinarian and circumstances for which the horse is examined. Research within the area has long tried to establish an objective and standardized method for lamenessevaluation in horses. Several methods have been shown to be reliable and are used regularly within research, for example measurement of forces between the hoof and ground, and measurement of movements with high speed cameras or accelerometers. However these methods require considerable preparation, standardization, and expensive equipment as well as produce large amounts of data that are incomprehensible for the clinician.

Simulering av miljoner grindar med Count Algoritmen

A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Småföretagsfördelar vid tillväxt

Growth of small businesses is vital to the Swedish economy, and many entrepreneurs want their enterprises to grow. However, the business climate of today is more changing than ever, and attributes becoming increasingly important for companies in order to deal with this are flexibility, speed, and adaptability: characteristics normally attributed to small enterprises. As a larger organization often is associated with more rigidity as a consequence of a higher degree of formalization, entrepreneurs are hesitant to seize growth opportunities, as they fear it will have negative impact on the aforementioned competitive advantages their enterprise possesses as a small business. This simple case study of a growing small enterprise investigates the effects of organizational growth on a small business' organizational structure and through its above mentioned advantages. The study finds that avoiding formalization while growing damages the competitiveness of the firm, and concludes that a degree of formalization is a necessity to maintain the flexibility, speed and adaptability in a growing small business..

Capacity studies on DeLavals sort gate DSG10

In the dairy production it is necessary to be able to sort cows. Dairy cows are sorted for many different reasons i.e. regrouping into production strings or for treatments i.e. inseminations, pregnancy and health checks, vaccinations or hoof trimmings. One labour saving way of conducting sorting is by using an automatic sort gate.
