This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.

When a car owner want to lock or unlock his or her car today, it?s preferable done by using aremote control. The system is really comfortable when the car owner is using the remote.A problem arises if a thief gets the remote.The thief doesn?t have to know where the car is parked, an approximate estimation where thecar is parked is enough.For instance, it?s enough to know which car park the car is parked in. If the thief knows that,he/she can repeatedly activate the remote control while looking for a car indicating with lightsand sounds.Because of the fact that a car usually indicates that it has been unlocked by making a shortsound indication, there will be no problem finding the car.The purpose with this project is to make a prototype which makes it harder for a thief to findthe car.

The aim of this report has been to investigate the use of electricity energy before and after a conversion of foodservice. The ambition was also to highlight the food safety and the retention of nutrients in relation to the conversion. The methods being used were qualitative interviews, case studies, study visits and literature. The equipment and the use of energy was the same in 2008 as in 2011 for hot-holding of the tested component, sauce with ham. The chilled system used more than three times the energy and cost for one portion than one portion in the hot-hold system.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

Syftet med den här uppsatsen är att beskriva hur ledarskap och ekonomistyrning skapar framgång hos fyra företag i Norrbotten samt att visa hur ledarskap och ekonomistyrning relaterar till varandra genom en styrnings- och ledarskapsmodell av Johny Alm. Studien har genomförts som en fallstudie av fyra företag verksamma i Luleå och Piteå. Från studien kan vi dra slutsatserna att kopplingen mellan ekonomistyrning och ledarskap är väldigt stark och att företag inte kan vara utan det ena eller andra. Slutligen kan vi säga att ledarskapet och företagskulturen tenderar till att vara viktigare än ekonomistyrningen för att skapa ett framgångsrikt företag..

Problem-formulering: Hur fungerar ekonomi- och verksamhetsstyrningen inom den kommunala verksamheten? Hur sätter kommuner mål och hur följs de upp? Är sättet att fastställa mål och mätmetoder likartade eller finns det skillnader?Syfte: Syftet med uppsatsen är att studera hur kommunerna Gnesta, Nykvarn och Salem styr sina verksamheter via uppsatta mål och hur de följer upp dem ur ett ekonomiskt- och verksamhetsperspektiv.Metod: En fallstudie har gjorts vid tre kommuner. Primärdata samlades in genom semistrukturerade intervjuer.Teoretiskreferensram: Den teoretiska referensramen baseras på olika formella och informella styrmedel. Som formellt styrmedel behandlas budget medan de informella styrmedel som tas upp är organisationsstruktur, målstyrning, balanserade styrkort, nyckeltal och benchmarking.Empiri: Kapitlet inleds med en presentation av kommunallagen. Vidare presenteras de undersökta kommunernas sätt att styra sina verksamheter.Slutsats: Kommuner uppvisar både likheter och skillnader i sina sätt att fastställa mål och mätmetoder.

Ett högt ohälsotal i arbetslivet innebär stora kostnader för samhället, arbetsgivare och även för de anställda. Forskningen inom detta område har flyttat fokus från att studera ohälsa till att istället studera hälsa och vilka faktorer som befrämjar hälsa i arbetslivet, de så kallade friskfaktorerna. Föreliggande studies övergripande syfte var att studera om upplevelsen av organisationsrättvisa och personlighets¬faktorn work locus of control predicerar upplevd hälsa hos kollektivanställda män och kvinnor. Studien genomfördes utifrån ett kvantitativt perspektiv med 103 deltagare som besvarade en enkät. Svarsfrekvensen var 22,5 % och resultatet visade att work locus of control predicerar upplevd hälsa för männen och procedural rättvisa predicerar upplevd hälsa för kvinnorna.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

Syftet med denna uppsats är att undersöka hur företagen samlar in information om kunden och därefter bearbetar informationen. Vi undersöker även om kundinformationen leder till förändringar, för att skapa långsiktiga kundrelationer, samt värva nya kunder för att slutligen bidra till ökad lönsamhet..

Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties. Biological control can be described as the suppression of damaging activities inflicted of a harmful organism by one or more other organisms, which are called antagonists or natural enemies. In Sweden, there are currently no registered biological control products available to control cucumber powdery mildew. The aim of this study was to investigate the effect of two biological control products in order to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level in greenhouse produced cucumber. In the experiments, different application regimes were also studied.

At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ?Familybox-system?. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years decreased because of new infections so we have to do something before shifting ownership! This degree thesis is meant to answer the question about which the optimal extension would be today. By studying literature, use my own experience and make lots of calculations, I try to find out different opportunities.

Background: During the 2000s, there has been an increased interest in studying business management and strategy implementation with customer focus in public organisations. To achieve business goals it is important to continuously work with strategies to meet customerdemands for increased efficiency and service. Purpose: The aim of the essay is to examine how to work on strategy implementation in a municipal real estate company from a management perspective in order to achieve overall goals. Method: The study?s methodology is a case study based on qualitative telephone interviews that were conducted with representatives in managerial positions from various levels of the company. The choice of the qualitative data was considered relevant in relation to the chosen topic of the thesis. The empirical data was then compared to the theoretical framework of the thesis. Results: Strategies guide the company to achieve the overall goals, which are later on broken down into operational targets.

Bakgrund: Grunden till området som på svenska brukar benämnas ekonomistyrning och på engelska"management control"lades av Anthony 1965 och dominerar än idag litteraturen på området. Sedan dess har dock ytterligare decentralisering och en orientering mot processer och flöden ägt rum i företagen. Detta, menar vi, inte har gjort några avtryck i"management control"-litteraturen. Syfte: Syftet med denna uppsats är att kartlägga den ekonomiska ansvarsfördelningen i svenska kommersiella decentraliserade företag. Vidare syftar uppsatsen till att beskriva hur personer ålagda sådant ansvar upplever detta samt hur dessa använder ekonomisk information.

One can find it problematic to communicate in today?s information society and therefore has the importance of distributing information the right way grown. Managers possess the authority to control what information is to be distributed how and that has created a big need for managers to learn how to communicate. This study was conducted in hope of enlightening the phenomenon male and female management communication. We chose to do a case study on two managers on Solna Stad in Stockholm. One male and one female.
