Standardiserad systemlösning för mikroföretag

The thesis is about exploring possibilities for developing a standardised system solution for micro businesses, this since most of the micro business lack proper system solutions, a contributing factor of this is price and also incompatibility between the solution and the business itself. The system solutions we will refer to are solutions which task is to cover the most important needs that a micro business might have on their system. The main goal with this research is to see if this is possible, and if so, how the developers should think to take it further. We chose to do this by identifying the most significant of needs a micro business has when it comes to this type of system solution.In this thesis we will present three needs which were evaluated and brought forth through the analyses of various interviews and observations we had done during the study. The interviews took place at respective company with their employees and consisted both closed and open questions with our main focus on the open questions because we wanted to obtain as much information from the respondents as possible from several viewpoints.

Vem bryr sig? : Ett kommunikativt perspektiv på fusionen mellan Växjö Universitet och Högskolan i Kalmar

This essay takes the three models from Allison and Zelikow book Essence of decision and applies them on the Swedish defense system. After the cold war the Swedish defense system had to undergo changes to be a more modern defense and be able to defend Sweden against threats. To also be able to cooperate with other countries in peacekeeping operations the Swedish defense had to be reorganized. The solution was to change direction from a defense system that was organized for invasion to instead be a movable defense ready for any challenge in Sweden or abroad. This reorganization will be analyzed according to the three different models..

Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga

This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..

Kvighotell : samarbete mellan mjölkproducent och rekryteringsuppfödare

This master thesis is about the collaboration between the custom dairy heifer grower and thedairy producer.The custom dairy heifer grower is a rather unusual strategy of reproductive management inSweden compared to other countries like U.S. and Denmark where the specialization withindairy production gone much further. In these countries the research also has reached muchfurther within this type of industry. However in Sweden there has been research made in thearea of collaboration, but then only within collaborations in the industries of crop production,dairy production and pork meat.The down going trend of profitability within dairy production together with poor profitabilityin the beef industry could partly remedy if more collaborations around heifer contractingwould arise. But since the industry still is of a rare kind in Sweden the knowledge about howthese types of collaborative arrangements works and their contracts are put together is poor.By that the aim of this master thesis is formulated as follows: "how is usually thecollaborative arrangement between the dairy producer and custom dairy heifer growerdesigned".

Egyptiska universitetsstudenters åsikter om det egyptiska utbildningssystemets förutsättningar att främja en demokratisk utveckling i Egypten

The purpose of this essay is to examine Egyptian university students´attitudes about the Egyptian education system´s ability to support a democratic process in Egypt. In order to carry out my study, scientific books and articles have been read and interviews have been made among Egyptian university students. The interviews contained questions about the Egyptian education system´s impact on the democratic process in Egypt and which impact the Egyptian education system has had on the Egyptian revolution.The conclusion drawn from my study is that Egyptian university students find the contemporary Egyptian education system based on authoritarian rules and with a lack of democratic values. The Egyptian university students believe that to establish democratic institutions in Egypt, the Egyptian citizens need a better understanding about democratic values. However, some of the students believe that the democracy that should be established in Egypt, must be based on Islamic values and to succeed with that, Islamic studies must play a greater part in the Egyptian education.When it comes to the Egyptian education system´s impact on the Egyptian revolution the Egyptian university students´opinions were somehow divided. .

Lantbrukare och rådgivare : tillsammans kan de främja biologisk mångfald.

With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.

Stabilitet och förändring i samband med en ERP-implementering : En fallstudie

Utvecklingen och användningen av ERP-system har blivit allt vanligare och trots att ett sådant system kan bidra med effektivitet kan implementeringen av ett sådant system innebära en omfattande organisatorisk förändring. Vid en förändring i form av införande av ny teknologi inverkar befintliga rutiner och institutioner på huruvida stabilitet kan upprätthållas. Stabilitet kan upprätthållas då nya regler går i linje med rådande rutiner eller vid närvaro av en lös koppling mellan dessa. Uppsatsens syfte är att genom en fallstudie undersöka om och isåfall hur stabilitet och förändring kan samverka vid implementering av ett ERP-system. Studien visar att detta är möjligt, dels tack vare att de anställda får vara delaktiga, att de inser förändringens huvudsakliga syfte samt att de nya reglerna går i linje med rådande rutiner och institutioner.

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..

A table was made where different timeschedules were accounted for the new press, with semi- and full automatic plate changing for present and to be added papers.

Borde Sverige gå från ett spelmonol till ett licenssystem gällande EMV lotterier? : En kostnadsnyttoanalys

The gambling industry goes from a national matter towards an international market. Since more and more members of EU does liberalise the gambling reforms and introduces a license system more participants will get an EU license for online gambling. With an EU license it is difficult for members of the EU to refuse a company to offer a gambling supply on the Internet if they don?t have an open license system. This paper tries to acknowledge the problem regarding the monopoly Sweden has today and calculate the effect if Sweden would move to a license system regarding online gambling by doing a cost benefit analysis.

Reglering av turbins ledskenor i vattenkraftverkmed hjälp av elektriska ställdon

Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

Prestandaförändringen hos en bergvärmeanläggning efter fem års drifttid

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

OSE och Linux : En studie om prestanda

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..
