Kvalitetssäkring:En analys av egenkontroll
A degree thesis about quality control and assurance in construction. Made in cooperation with Wästbygg. An analysis was made of the self-monitoring control that is conducted during the construction. The data was collected from interviews from personnel employed by Wäsbygg as either work-leader, project-manager or quality- and environmental-coordinator. During the study there was also a review of the literature in the subject.
Publika private equity-bolags påverkan på styrningen av sina portföljföretag. En fallstudie av styrmekanismernas utveckling under ägarperioden.
Recent years have been very turbulent for most private equity firms. Especially the financial meltdown in global economy has affected the industry, but also the public pressure has made private equity houses change their control strategies towards more conventional methods used in public companies. This thesis aims to put light on the control methods used in listed private equity houses which use a buyout strategy. The paper describes how the control methods change over the different phases the asset experience and how different value generating strategies use altered control methods. Using Merchant's (2003) framework for management control systems and Berg and Gottschalg's (2004) research on value generating strategies in buyouts the thesis shows that action controls as designing instructions for the board and a business plan, together with goal alignment is the commonly used control strategy directly after the acquisition.
Reglering av veka strukturer med multipla sensorer
In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.
FRAMTAGNING AV INSTALLATIONSKIT FÖR PROJEKTILINMÄTNINGSYSTEM
The report presents a thesis carried out on behalf of the company SAAB Training and Simulation which is situated in Huskvarna. The authors of this report are going to graduate as mechanical engineers focusing on product development and design, and this thesis should reflect the knowledge obtained during the education. The assignment, given from the company was to develop a concept of a stand that will constitute as a part of a mobile system for target practice. The reader get to follow throughout the project and can hopefully learn from the smart solutions and approaches that have arisen during the process.Today SAAB doesn?t have a mobile application in their portfolio that utilizes the benefits of their sensor measuring system, also called the LOMAH-bar.
Förlossningsupplevelsen. Ett designtillägg i förlossningssalen med fokus på mental ergonomi.
In this project I have created a design for the delivery rooms of Swedish hospitals with the psychological aspects ofbirthgiving in focus. This is something that I think the delivery rooms lack and so far it has been the midwifes job to,without any tools, give the women in labor the mental support and encouragement they need.My goal was to give the midwifes a tool to work with when it comes to encouragement, something helping themhelping the woman to feel safe and relaxed, strengthened, informed and in control of the situation.I choose to focus on the difficulties measuring the physical work the woman in labour had done and what was leftof the labour. I wanted to visualize the process of the birth, allowing the woman to see and being able to focus onwhere during the labour she is, how far she has left and also being strengthened by the amount of work already managed.Further I wanted to make the woman feel invited to take control over the birth and the room in which she isin labour. I wanted her to be able ? if she wanted ? to make her own settings of the mood in the room, deciding forherself if she wanted a more relaxed environment or perhaps a more energetic.
Vi har i alla fall tipsbolag : En studie av möjligheterna att styra med belöningssystem inom kommunal verksamhet
Background: The use of reward systems can be of strategic importance as well as an affective mean of control for the organization in its work to achieve its goals. The municipal sector is characterized by its transparency and its responsibility for the taxpayer?s money. We therefore wonder which possibilities the municipal sector has to use reward systems as a men of control. Purpose: We intend to research the possibilities that the reward system offer as a mean of control for employees at the higher municipal level, with a special focus on commitment and motivation.
Aktiva trasdockor med samverkande kontrollsystem i dataspel
Animation av karaktärer är en viktig del inom dataspel. Den interaktiva, oförutsägbara naturen av spel kräver att karaktärer måste kunna reagera dynamiskt på händelser i miljön för att upplevas som realistiska. För att göra detta möjligt räcker det inte att använda tekniker baserade på förinspelad animationsdata eller fysisk simulation av karaktärer i medvetslöst tillstånd.Ett system som kombinerar kontinuerlig fysisk simulation av karaktärer med ett kontrollsystem baserat på förinspelad animation åstadkommer fysiskt korrekta rörelser hos en karaktär. Genom att utöka ett sådant system med introducerandet av möjligheten för flera samtidigt samverkande kontrollsystem, baserade på dynamiska såväl som förinspelade tekniker, i ett uniformt interface kan en karaktärs rörelser modulariseras. Detta tillåter sammanställandet av en ?verktygslåda? av rörelser.En sådan uniform verktygslåda, kombinerad med en kontrollerande artificiell intelligens, gör det möjligt att utveckla fullt självständiga virtuella karaktärer i en dynamisk miljö..
Kan en central strategi leva lokalt?: En fallstudie av Sveriges ledande spelbolag
This thesis examines the approach for implementing strategy that has been applied by the study object, Svenska Spel. The specific approach originates from the theories of Elliot Jaques, whose key proposal is that individuals have different capability of carrying out tasks over different time-spans. The main purpose of the study is to analyze how the approach has influenced the management control systems in use, in order to ensure that the strategy is successfully implemented on corporate as well as operational level. Twenty in debt interviews conducted with employees, representing a vertical cross section throughout the organization, are the main source of the study?s empirical foundation.
Långtidsarbetslöshet och personlighet
Studien syftar till att se hur personlighet, söka-arbete self-efficacy och locus of control påverkas av arbetslöshet. Personlighet mäts enligt Costa & MacCraes fem-faktor modell och avser dimensionerna extroversion, neuroticism, öppenhet, trevlighet och samvetsgrannhet. Hypotesen är att det finns skillnad mellan nyarbetslösa och långtidsarbetslösa avseende personlighet, söka arbete self-efficacy och locus of control. Frågeformulär innehållande påstående om ovanstående faktorer besvarades av en grupp nyarbetslösa och en grupp långtidsarbetslösa. Resultatet visar inga signifikanta skillnader avseende personlighet och söka arbete self-efficacy mellan grupperna.
Design av PID-regulator baserad på kommersiell processormodul
The idea to develop a platform for a PID-controller came from the need to control the temperature in an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.
Pilotstudie för utformning av modell att uvärdera utrustning
Swedish Trotting association was formed in 1925. They are the ones who design the regulations concerning what is permissible and not permissible for the horse, driver and trainer, when they have a license at a Swedish racing track. The Veterinary department of Swedish Trotting association decides in consultation with representatives from veterinaries around the country what is allowed and not allowed, based proven experience, combined with the availability of scientific data and Veterinary Department's own assessment.
After stricter regulations for good animal welfare from the Swedish government, Swedish Trotting association is going to work out a workable model for how new equipment can be tested in the future to see how the equipment affects the horse. In the future, all equipment will be objectively tested before approved. The purpose of this work was to develop a well-functioning model for this.
The research-question for this work is:
Is this study design a well-functioning model of how the equipment should be tested in the future?
The equipment used for designing this model was bitless bridle with a bit.
Hantering av risk i en Leveraged Buyout-miljö: Ägarförändringsklausulen, ett nytt fenomen?
The change of control clause is nowadays a well used covenant in the Eurobond market, with the aims to protect bondholders in case of a leveraged buyout. This thesis intend to evaluate whether the change of control clause is a new phenomenon in the Eurobond market today and to estimate what have been the driven force for the popularity of it. The thesis found that the change of control clause already existed before and thus it is not a new phenomenon. Several factors where found though to explain the extended use of the clause today. Starting in 2005 the LBO activity increased rapidly, exposing almost every company to the risk of LBO.
Sjuksköterskans erfarenheter av mötet med patienter med ett annat modersmål : - En litteraturöversikt
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)..
Mobile first design vs. desktop first design : En jämförelse av en prototyp och en befintlig webbplats ur ett användbarhetsperspektiv
Detta examensarbete har haft till syfte att åskådliggöra eventuella skillnader och/eller likheter i den upplevda användbarheten vid användandet av en webbplats skapad via mobile first design och desktop first design. Målsättningen med examensarbetet har varit att ta fram en hifi-prototyp, skapad utifrån mobile first design, som visualiserade ett designförslag för flygfotoföretaget HimlaFotos startsida. Jämförelsen har utgått ifrån en egendefinierad version av begreppet användbarhet baserad på ISO:s definition, där användbarhet består av tre faktorer; kraftfullhet, effektivitet och tillfredställelse. För att samla in data om den upplevda användbarheten har användartester genomförts. Flera likheter har identifierats gällande användbarhetsmåtten kraftfullhet och effektivitet, medan skillnader har funnits vid måttet för tillfredställelse.
Fluid Simulation for Visual Effects
This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..
