Alternativa produktionsmetoder vid anläggningsarbeten Kringgjutning av el- och telekabelkanalisation
I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.
Private Equity-bolags styrning av portföljbolag; En fallstudie av värderingsmodellens översättning till olika organisationsnivåer.
The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.

Intern kontroll och ERP system : En explorativ studie i hur den interna kontrollen påverkas under implementeringen av ett ERP system
Denna explorativa studie beskriver hur den interna kontrollen i organisationer kan påverkas under implementeringen av ett ERP system. Intern kontroll är en del av organisationens ekonomistyrning och består av organisationens rutiner och aktiviteter för att undvika risker och säkerställa att organisationens mål uppfylls. Eftersom implementeringen av ett ERP system är en riskfylld process är det viktigt att förstå hur den interna kontrollen påverkas. För att undersöka detta används i studien ramverket Internal Control - Integrated framework. Datainsamlig genomfördes på en stor IT-organisation där ERP systemet Navision 2009 implementeras och 10 respondenter från olika avdelningar intervjuades.
ACTa våra stressade lärare: en randomiserad studie om Acceptance & Commitment Therapy (ACT) för stressade lärare
The present study examines the effect of a nine-hour Acceptance and Commitment Training (ACT) intervention for teachers who experience stress. Twenty-two teachers from four different counties in southern Sweden were randomly allocated to an ACT intervention (n=15) and a control group (n=7). The ACT condition received three three-hour sessions of ACT over a six-week period, and the control group received a three-hour stress lecture at one occasion. At a follow-up four-weeks after completed intervention, ACT participants showed significant in-group differences on stress, psychological flexibility, general health, and burnout. At a between group comparison, only psychological flexibility was significantly enhanced at the follow-up.
Hastighets- och positionsinterface för motorer
The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.
Val av stommaterial : Vilket är det mest fördelaktiga stommaterialet vid uppförande av en hallbyggnad?
When constructing an industrial- or hall building, the most common framework materials thatis used are wood, steel or concrete. Due to an assignment from Byggnadstekniska Byrån ABhas a document been created that makes it possible to investigate how the final costs is af-fected by gapes in between elements and which used foundation. And this with steel as thematerial. The purpose with this essay is to investigate which is the most well fitted materialwhen constructing an industrial- or hall building wood, steel or concrete. Information aboutthe different materials has been collected by litterateurs and by different internet pages.
Att testa kvalitet : En validerande informationsinsamlingsmetod för ökad kunskapsåterföring
This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.
Interorganisatorisk styrning av leverantörsrelationer inom lågprismodebranschen: -En fallstudie av lågprismodeföretaget BikBok
This thesis concerns the control of outsourced interorganizational buyer-supplier relationships in the low-price fashion industry. A qualitative case study has been performed on two supplier relationships of a low-price fashion company. By identifying specificities of the industry and relating them to control problems and their implications on control solutions, the thesis has established a relation between industry specific characteristics and the way companies in the industry control their supplier relationships. The analysis is based on a theoretical framework created by Dekker (2004). Amongst other factors, the difficulty to define, quantify and measure the design variables of a fashion good, the high heterogeneity between individual products and the difficulty to predict the trend based demand, create high coordination requirements as well as appropriation concerns solved through extensive formal control.
Projekthanteringssystem
This document is a summary of my work to create a project management system for
a small firm working with computer graphics. The intention is to manage
customers, projects, images and invoices in the easiest possible way. To make
the system as flexible as possible a web-interface was chosen which makes it
possible to access the system from any computer, making it independent of any
particular operating system. The only requirement on the user environment is
that the computer must have a connection to the Internet to be able to access
the system. The different techniques that have been used to develop the project
management system is primarily Ruby on Rails and a MySQL database.
Although Ruby on Rails was completely new to me, I decided to use this
framework instead of PHP, which I
already have a good knowledge of, because of the benefits Ruby on Rails
provide.
Prototyp av informationssystem för militärfordon
Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.
Kungsängsverket : ett reningsverk omvandlas till park
Today, there are few industries left in our cities. Industrial areas thatare located in urban settings close to water or city centers are oftenreplaced by housing. In my thesis I want to explore how such industrialsite located in an urban setting can be transformed into anindustrial park where the industrial structures are saved. By approachingthis type of environment in a positive manner, I wish tohighlight the potential aesthetic and functional value in the existingindustrial structure. Through the transformation and design of anexisting industrial site I will convey the previous use and history ofthe place.The wastewater treatment plant, Kungsängsverket, is located in thedistrict of Kungsängen in the southern part of Uppsala.
Undersökning av ramverket IF/ELSE:s applicerbarhet på vården
De flesta organisationer är beroende av kommunikation mellan olika individer både inom och utanförorganisationen för att fungera. Effektiviteten speglas ofta av kvalitén hos denna kommunikation. Detfinns många parametrar som påverkar kommunikationssituationen (fackspråk: interoperabiliteten)inom en organisation, t.ex. företagskultur, arbetsrutiner, språk, IT-system ochkommunikationsmedium. För att kunna påverka situationen krävs att man identifierar de involveradeparametrarna och sambanden emellan dem.
