Studie av integration mellan rategyron och magnetkompass
This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.
DUBBELDIAGNOS Upplevelser av bemötandet från psykiatrin, socialtjänsten, omgivningen och personalen på boendet.
With this study, we have chosen to continue our B-essay about dual-diagnosis.
In the essay we have done some research on how this target group feels about the treatment from the dependent unit, psychiatry unit, social services unit and the housing environment. We wanted to know about the feelings because during the B-essay we found out that individuals whit the dual-diagnosis is skipped between different caregivers. We used a qualitative method with six interviews from two different housings in south of Sweden. The information we got we used in our result and analysis part, where we found out that the caretaker?s thought the treatment were fine and that it was the surroundings they found the most fault with..
Styrelsesammansättningens påverkan på revisorsarvodet
Introduction:By insight in the company and by monitoring the management, the board has an important function in creating trust in governance of the company. Furthermore, the board reduces the asymmetry of information between the owners and the management, which also is the function of the auditor, by auditing how the board governs the company and the accounting. In case the board does not effectively monitor the management, the auditor has to extend its monitoring, which increases the owners agency costs through the audit fee. The board composition can affect how effectively the board practices the monitoringProblem: How is the audit fee affected by the board composition?Purpose: The purpose of this study is to explain how the board composition affects the audit fee.Method: The study uses a quantitative method, where the data was collected from the annual reports of 112 limited companies listed on the NASDAQ OMX Large and Mid Cap lists on January 2, 2012.
Utveckling av ett hjälpmedel för träning och utvärdering av förare av tunga fordon
The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.
Feldetektering för diagnos med differentialgeometriska metoder -en implementering i Mathematica
Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.
Framtidens elbilar utmanar nutidens elnät : Påverkan av ett ökat antal elbilar på ett halländskt elnät
The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.
Utvärdering av CTI på virkesfordon : ? CTI-projekt Holmen Skog/Örnfrakt 2005-2006
The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility
Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure.
The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.
Vilken information och instruktion om munhygien, kost, fluor och tobak med hänsyn till diagnos får patienter som behandlas av tandhygieniststuderande vid Högskolan Kristianstad?
ABSTRACTWhat kind of information and instructions with the consideration to diagnosis do patients, treated by the dental hygienist students at the University Kristianstad, get regarding oral hygiene, diet, flour and tobacco.The aim of this study was to examine what kind of information and instructions regarding oral hygiene, diet, flour and tobacco have patients treated by the dental hygienist students at the University Kristianstad, if they had the diagnosis caries or periodontitis. The study is based on a review of dental records of adult patients from twenty years on a supportive treatment program. In all 640 patients were enrolled at the clinic, 20050309. A selection of 100 patients treated at the clinic from 2000 was made. Fifty off the dental records should have the diagnosis caries and fifty the diagnosis periodontitis.
Diagnosens vara eller icke vara - det är frågan: en studie om den neuropsykiatriska diagnosens betydelse
Occasionally the views of medicine and social sciences can collide. Doctors typically relate to a explanatory biological model, and social workers and psychologists seek social and historical reasons for neuropsychological diagnoses.A diagnosis is an obligation for medical doctors as well as other professionals within Child and Adolescent Psychiatry, and a neuropsychological diagnosis is a prerequisite for treatment and more often than not for other forms of support from society.The aim of this study is to examine the function of a neuropsychological diagnosis with regards to the individual patient, Child and Adolescent Psychiatry and society. A second aim was to examine how psychologists and social workers trained in the social sciences view neuropsychological diagnoses.Qualitative interview research methods have been used. Most of the interviews were recorded and transcribed in their entirety. The data has been organised into appropriate categories and the most relevant quotes have been selected.
Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor :
The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.
Barns uppfattningar om och förståelse kring sin dyslexi : En studie i hur barn upplever sin dyslexidiagnos
AbstractThis act is about how five children with dyslexia consider and understands their diagnosis. It is also about their self-image, future sights and about how their school life is compared with before they got their diagnosis. The study is implemented autumn 2011 on a medium-sized school in central Sweden. The survey was implemented through interviews with the five children, of which four was girls and one was a boy. The study shows that the children understand their dyslexia relatively well, but that they experience that it is bothersome to live with dyslexia.
Utvärdering och implementering av automatiska farthållare i fordonssimulator
Vehicle simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice simulator will be described and a comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.
Barn med ADHD-diagnos : En studie om den sociala miljöns inverkan på beteenden som föranleder ADHD-diagnos
The purpose of this study was to illustrate how professionals, who work with psychosocialproblems among children, look at the impact of social factors on behavior that causes ADHDdiagnosis and at the relationship between social factors and the increased diagnosis that hasoccurred in recent years. To answer our purpose, we chose a qualitative approach byinterviewing six professionals who had different professional affiliations. We analyzed theresults using systems theory and attachment theory. The results showed that the professionalssaw various social factors that influenced the behaviors that cause ADHD diagnosis, particularlytroublesome growing environment and the school environment that requires greater cognitiveability and social skills of children today. They also saw that social factors could have an impacton the increase of diagnoses, particularly that the diagnosis can result in that the understandingchanges and that it is considered easier to get extra support at school with a diagnosis..
