Detektering av in- och utandning vil bilkörning med hjälp av Matlab

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

Att bli värdigt bemött : En tvärsnittstudie om bemötande på akutvårdsavdelningar ur patientens perspektiv

Previous research and patient complaints to the Swedish Patient Support Committee shows that there is a lack of substance in the patient-nurse relationship. This may suggest that it can be difficult for health care to live up to health-care law which requires it to be of good quality, based on dignity and respect and designed so that the patient is an active participant and can make their own decisions when it comes to their health care. For a better understanding of what a dignified patient-nurse relationship is, this study aims to clarify what the patient values as good patient-nurse relationship and describe how they have experienced the patient-nurse relationship during their stay at an emergency care department. The study is a descriptive cross-sectional study with a quantitative approach, where the population consisted of patients who were cared for at an emergency care department in the County of Västmanland, Sweden during 2007. The sample consisted of 93 patients which were asked to answer a questionnaire.

Target Capital Structure and Adjustment Speed- a dynamic panel data analysis of Swedish firms

The purpose of this thesis is to test whether firms have target capital structure, and if so with what speed they adjust toward this target. Findings that support this purpose are also in line with the trade off theory. One of the key elements of this thesis is the method used, which successfully enables fulfilling the purpose. The panel data method captures the data characteristics of the cross sectional and time series dimension. By using this approach the dynamic effects of capital structure can be studied, thus if there actually is an adjustment towards a target the speed can be estimated.

We applied a qualitative method for research of the project to provide a high-quality empirical work. The result shows that by using well-structured story early in the design process you will easily succeed with your cross media design..

Cross-suckling when sows are group housed during lactation : associations with sow productivity and behaviour

Cross-suckling, i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of knowledge regarding cross-suckling increases. The overall aims with this thesis was to investigate how sow behaviour and productivity are associated with the occurrence of cross-suckling, and to investigate consistency in sow nursing behaviour related to cross-suckling. The study included information about the first 4 parities of 40 LxY sows kept in outdoor and indoor production environments. Sows were single housed the first 2 weeks after farrowing and group housed (4 or 5 sows per group) from 2 weeks after farrowing until weaning, 7 weeks after farrowing.

Marknadens värdering av redovisningskvalitet

The purpose of this thesis was to investigate whether accounting quality is a priced factor by investors. The event studied is the release of year-end result and the release of the annual report. To assess accounting quality a sample of 30 companies listed on the Stockholm Stock Exchange during 2003 to 2007 are studied. We assess accounting quality by the absolute size of discretionary accruals using the modified Jones model developed by Dechow et al. (1995).

Dog bite incidence and associated risk factors : a cross-sectional study on school children in Tamil Nadu

Dog bites pose a threat to public health globally and can lead to infection, disfigurement, incapacity, post-traumatic stress syndrome and even death. In geographical areas where rabies is endemic, bites from infected dogs account for over 90% of the human rabies cases. Children have been proven to be at a greater risk of being bitten by dogs and subsequently contracting rabies than adults. In this cross-sectional study, a school survey was undertaken in association with a rabies awareness campaign in India, to investigate the dog bite incidence and various risk factors associated with dog bites as well as assessing the knowledge of safe interaction with dogs among children in the age group 10-18 years. A total of 1295 questionnaires were collected. 43.2 % (n=556) out of the respondents were boys and 56.8 % (n=731) were girls with a mean age of 14 years.

Arbetsmotivation och psykisk hälsa bland sjuksköterskor inom psykiatrin : En jämförande studie mellan yngre och äldre sjukksöterskor

Background: The relation between work motivation and well-being are relatively well theoretically entrenched, but few studies have been conducted on nurses within psychiatry. Objective: The aim of the present study was to examine the differences in intrinsic work motivation (autonomy, competence, relatedness), mental health and burnout between young (?40 years) and older (>40 years) nurses employed in psychiatry. Method: The study was an observational study with a cross-sectional design and group comparisons, conducted as a survey. The sample constituted of 60 employed nurses.

Att vara eller inte vara i riksdagen : -en uppsats om två prognosmetoder för svenska riksdagsval

I uppsatsen kommer potentialen att prognostisera utfallet i svenska riksdagsval med logistisk regression och Seemingly Unrelated Regression (SUR) att undersökas. Estimeringarna baseras på svensk valdata från 1973 och framåt. Modellerna inkluderar makroekonomiska variabler såväl som indikatorer över de regeringens popularitet samt en tröttnadsvariabel. Resultaten tyder på att varken logistisk regression eller SUR är lämpliga att använda för prognostisering av svenska riksdagsval. Logistisk regression kräver en sådan förenkling av det politiska landskapet att några meningsfulla slutsatser är svåra att dra.

Cross-sectional study of the prevalence of Babesia bigemina in Uganda : wildlife-livestock interface at and around LMNP

Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. This cross-sectional study was conducted to establish and compare the sero-prevalence of the tick-borne pathogen Babesia bigemina among randomly selected Ankole Long-horned cattle and European crossbred cattle on 30 farms in Kiruhura district, in two sub-counties near Lake Mburo National Park in South-western Uganda. Half of the farms were situated in close proximity to the park and thereby housed cattle with more frequent wildlife-livestock interface (Sanga), whereas the other half had less frequent contact (Kikatsi).

Inkrementell responsanalys : Vilka kunder bör väljas vid riktad marknadsföring?

If customers respond differently to a campaign, it is worthwhile to find those customers who respond most positively and direct the campaign towards them. This can be done by using so called incremental response analysis where respondents from a campaign are compared with respondents from a control group. Customers with the highest increased response from the campaign will be selected and thus may increase the company?s return. Incremental response analysis is applied to the mobile operator Tres historical data.
