HIIT och dess effekt på löpekonomi hos vältränade löpare och triatleter
Background: Running economy is one of the key factors to achieve top performance in endurance events. Little evidence exists for improving running economy using high-intensity interval training while running. Objectives: The purpose of this study was to examine how HIIT affects running economy and VO2max. Method: 14 well-trained athletes (age 35 ± 8,9 years, height 175 ± 11,7 cm and weight 69 ± 12,2 kg) were divided into two separate groups (HIIT and Control). HIIT group performed 3 HIIT exercises every week for 4 weeks and Control group continued with their separate training programs consisting of mostly traditional endurance training. Results: Running economy showed no improvement in HIIT (pre 38,62 and post 38,62 ml/kg/min, p=1.00) but Control improved (pre 45,41 and post 43,37 ml/kg/min, p=0,03). VO2max decreased in HIIT (mean 61,32 to 60,84 ml/kg/min) and in Control (mean 61,99 to 58,47 ml/kg/min)..
Deriving ECA-rules from timed-automata specifications.
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Alternativ för värme- och kylaförsörjning i planerade kontorsbyggnader på Arlanda
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.
Avståndets inverkan på styrningen: -en fallstudie hos Vin & Sprit
The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.
Car Lock Improved by Configurable Key
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.
Varmhållen och kyld skolmat : En jämförelse med fokus på energianvändning mot bakgrund av livsmedelssäkerhet och näringsretention
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.
En indirekt metod för adaptiv reglering av en helikopter
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.
Predicerar organisationsrättvisa och work locus of control hälsa hos kollektivanställda män och kvinnor
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.
Automatisk bedömning av reglerkretsarsprestanda
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.
Biological control of powdery mildew in greenhouse produced cucumber : an evaluation of two microbiological control agents
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.
Vasakronan: Det bästa av två världar
Mergers and acquisitions are common phenomenon in today´s society in order to increase shareholder value. Two years ago a fusion of Sweden´s two largest companies in the industry of real estate took place and even though three out of four mergers and acquisitions financially fail this certain case turned out highly successful. The aim of this thesis is to examine how the organizational structure and the management control have been designed and characterized the organizational performance and furthermore what are the success factors of the integration. By studying an acquisition and its potential effects on organizational structure and management control parallel to a model that describes the best practice guidelines for managers to successfully deliver value from their acquisitions, it can be shown that an acquisition has direct effects both on the acquirer and the acquired company and thus the new organizational structure. The main results, thus, is that through active leadership, increased specialization, and more decentralized and thus efficient management control a new organization has emerged consisting of the best features of two separate worlds..
Gemensam struktur för den kommunala ekonomistyrningen
Municipalities must establish budget annually but they are free to decide how the governance should be designed, this can lead to lack of consistency and measurability within and between municipalities. The purpose of this thesis was to present a proposal for a unified and more measurable financial structure of a municipality where this was lacking. In our theory we describe the issues of traditional management control and we introduce an alternative control with non-financial ratios included, called the Balanced Scorecard. In the empirical data it is investigated how the governance of a municipality could be designed, according to the respondents. In the analysis the information gathered to reach the answers to what are considered to be useful governance in municipality, are examined. In the conclusion, we design Balanced Scorecards with both financial and non-financial ratios to the councils of the municipality..
Bedömning av området energi : En jämförelse mellan Miljöbyggnad, Svanen, FEBY12 och PHI
The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.
En fallstudie av konsult-klientsamspelet vid ERP-implementering. : En fallstudie från den Polska marknaden.
For many providers of ERP-system, Poland is one of the most valuable markets in Central andEastern Europe. The Polish market for ERP-systems is still a growing market, especially; wecan see the low utilization of ERP-systems among small and medium-sized enterprises. Thisis due to several factors, primarily the cost of implementing the system and the necessary infrastructure.Subsequently due to the lack of knowledge, where there is no sufficientknowledge of the benefits arising from the use of an ERP-system in their business, and thereis a fear within the companies that its business would start stagnating.This paper investigates the implementation process of a Polish consulting company whichworks towards small and medium-sized businesses. The key success factors will be studied inthe implementation of ERP-systems, and the instance factors of the interrelationship betweenthe consultant and client from a consultant perspective. The review of the literature has beenidentified and discussed in relevance to the empirical study.
Framtidens lagefterlevnadsverktyg hos små och medelstora företag : en behovsanalys
This thesis aims to investigate what requirements companies have in order to achieve a successful legislative compliance control. The implementation of an environmental management system can help the company to structure their business and succeed with their environmental legislative compliance.Both small and medium sized businesses perceive that it is difficult and time consuming because the legislation can be difficult to interpret if you do not have the required knowledge. There are many companies that hire help in the form of consultants who audit their compliance, but this leads to a risk that the company will be exposed when the knowledge does not remain in the company if the consultant would cancel the cooperation. There are not so many tools today for businesses to obtain good legal compliance. The methods used are usually checklists included in the control program, and it costs a lot of resources to do everything needed.This study strives to deliver the expressed needs of the businesses.
