Diagnostisering av projekt : En studie med utgångspunkt från SPA-ramverket
The work in project has been around since humans began to hunt in groups, building bridges or building of the Great Wall of China. In 1960- and 70´s, the word project got their value it has today. A project means a work done during a decided time, with decided economy and non-recurring nature (Jansson and Ljung 2004). The projects had a general analytical model. It was used for all projects the organization engaged.
Modeller för brösthöjdsålder för tall och gran :
The purpose of this study was to develop two types of prediction models for Scots Pine
and Norway Spruce. The first type for calculation of the stump diameter under bark the
year the tree reached breast height (Dstubh130). The second type for calculation of the
annual difference, e.g. the number of growth years between stump height (0.2 m) and
breast height (1.3 meters above ground level). The primary thought with these prediction
models is to obtain the breast height age in the trees on basis of the number of annual
rings at stump.
Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :
Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.
Empiriska växelkursmodeller för den svenska kronan - Är det någon som fungerar?
The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..
Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.
Centralitet och periferi i det nya Europa : Städer som regionala nav i samarbete och konkurrens
European cities of today are under the challenge to find ways to stay competitive and flourish in a rapidly changing world, where the old patterns of centrality and periphery not necessarily holds true. New and improved communication networks, a changed political geography in Europe, and the globalisation of not only the financial and industrial markets but also to a certain extent the globalisation of people, have all led to great challenges for cities and regions.In a changed spatial reality the classic monocentric models are challenged by newer models of urbanisation. The polycentric urban region is one such model which has been used to describe urban regions like the Randstad in the Netherlands and the Rhein-Ruhr region in Germany. Regions which lack the single dominant central city of the monocentric models of old, and instead shows a high degree of more equal-sized and sometimes more specialised cities in regional cooperation. The polycentric urban region is in that aspect a possible model for how other urbanised regions in Europe may act to be able to position themselves as attractive urban regions and regional hubs in the European urban network.Polycentric urban regions are not a universal solution, though.
Mobilt community - Bygga själv eller hjälpa till? : Kommersialisering av en plattform för användardriven karttjänst i mobiltelefoner
Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.
Gränslös välfärd? En studie om den europeiska integrationen har nått området välfärd genom sysselsättningspolitiken
Social policy has now received an increased attention in the European Union. The European welfare states experience a high level of unemployment, which the EU now tries to handle through the European Employment Strategy (EES). The core of this essay is whether the welfare institutions of the European member states are integrating through an institutionalization process or not. Within the EU four different types of welfare models can be identified: the Scandinavian, the Continental, the Southern and the Anglo-Saxon. The welfare models differ in the institutional settings e.g.
Vad påverkar en aktieanalystillförlitlighet? : En kvantitativ studie om relationen mellan tillförlitligheteni en aktieanalys och dess innehåll.
A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the reliability on the equity research and their practical use.
BPR och TQM: jämförelse mellan teoretiska modeller och dess tillämpning
Managementmodeller med inriktning mot processorientering blev populära i slutet av 1980-talet och början av 1990-talet och ett flertal olika modeller togs fram, marknadsfördes ivrigt av konsulter samt implementerades i många företag. Några av dessa modeller fick större genomslagskraft än andra. Många av dessa modeller blev så kallade managementtrender som fick stor uppmärksamhet under en period men sedan försvann. Litteraturstudier förde oss in på att Total Quality Management (TQM) och Business Process Reengineering (BPR) är två modeller som rönt stor uppmärksamhet. Det som intresserade oss vid litteraturstudierna var att studera hur dessa modeller upplevs i näringslivet idag, 10-15 år efter att de slagit igenom.
När barn behöver stöd i skolan : Direkta och indirekta målformuleringar
The aim of this thesis was to investigate the relation between different kinds ofremedial teaching models, not specifically addressed to pupils with physicaldisabilities, in the Swedish school context, and to describe and analyze theobjectives related to each model. Research focus was held on professionaldescriptions of school related problems and arguments for different kind of models,but also on objectives formulated in Swedish school policy. As theoretical toolswere used discourse analysis and interpretive policy analysis. The concept ofalienation as it appears throughout Foucault?s work was also used to understand howdifferent knowledge fields as education, special education, psychology and medicinedivide themselves from each other.
????Att lösa reglertekniska problem med Modelica
Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.
Järnåldersboplatser och historiska byar : En studie av agrara bebyggelsemönster i mälarbygder under 1500 år
Following paper deals with the questions about prehistorian and medieval settlements in the Mälar Valley and their relations to the historically known hamlets or single farmsteads from the 17th- and 18th-century cadastral maps. Models over settlement development through the period A.D 200 to 1700 done by geographers Ulf Sporrong and Dan Carlsson are tested and compared to the knowledge won by recent archaeological excavations. Is there a connection between the older settlements linked together by dry-stone walls and the late Iron Age settlements? Does the picture differ from the one presented for the Gotland region? How well are the general theories about different settlement development depending on basic natural conditions as for the potentials for cultivation and topography, corresponding to the physical remains? Are there other factors involved when the settlement structure takes its form?The methods that are used here constitutes mainly of a comparison between different locations in the Mälar Valley that has got a well known prehistory thanks to extensive archaeological excavations. Cadastral maps, soilmaps, topography maps and maps over ancient monuments are intertwined to the same map and analyzed through works in Geographical information systems.The results of this study reveal an interesting suspicion in the continuity-question through the Iron Age.
En studie av miljöfaktorers betydelse för förekomsten av Francisella
This thesis aims to analyse relations between the risk of Francisella in endemic areas and environmental variables. The thesis also discusses relations between occurrences of Tularemia and meteorological factors. The analysis resulted in several significant models that explained the occurrence of Francisella. These models can however only be applied to the year 2004 since there were too few test performed the other years, therefore no comparisons could be made. Another conclusion was that the relative humidity was significally higher in the year 2003, the same year as the occurrences of Tularemia was at its peak. .
Medborgarskap och immigration ? En kartläggning över utvecklingen i Tyskland och Frankrike sedan 1992
Citizenship and immigration policy are controversial aspects of the European integration project. Fourteen years ago Roger Brubaker stated that the vital differences between German and French citizenship policy were unthinkable to harmonise. This paper therefore seeks to investigate whether the old image of the two countries are accurate. By evaluating citizenship and immigration policies in today's context with the increasing influence of European Union policy I here present a more correct picture of the situation in both countries. Partly to see how the harmonisation has come this far.
