Filtyp
In this paper we discuss the problem of finding a suitable filter used as prefilter at digital Kalman filtering. The process is described by a stochastic state model. Two different filters are analyzed: a low-pass filter and a mean value filter. Especially we examine optimal choices of the parameters of the filters i.e. optimal integration area in the mean value filter and optimal time constant in
Barnahus is a Nordic model for collaboration between different authorities regarding the issue of child victims of crime. As this means that different work logics interact, some argue that Barnahus can be seen as affected by juridification, which is a term that describes how law enforcement is prioritized over care-oriented services. The purpose of this study was to explore how coordinators of dif
Bakgrund: Arbete är en högt värderad aktivitet i dagens samhälle. Effekten av arbete har en betydande roll för individens hälsa och ur ett samhällsekonomiskt perspektiv. Nationella riktlinjer rekommenderar arbetsrehabiliteringsmodellen Individual Placement and Support för personer med allvarlig psykisk sjukdom och har god evidens för arbetsåtergång inom diagnosgruppen. Primärt har studier undersökIntroduction: Work is a highly valued occupation in today’s society and plays a significant important role for individual’s well-being and also out of a socio-economic perspective. Individual Placement and Support is an evidence-based model for vocational rehabilitation developed and standardized for people with severe mental illness. Studies show that the IPS-model have been implemented for new p
Det finns många svårigheter med att tillverka livsmedelsprodukter som är emulsioner. Syftet med detta projekt var att utveckla en emulsion enligt krav som beställaren av produkten hade satt upp. En första utveckling av produkten skedde ungefär ett år tidigare, och den fortsatta utvecklingen baserades alltså på denna produkt. Det som hade blivit ett problem med den första utvecklade produkten var aIt is a difficult process to create a drinkable food product that is an emulsion. The aim with this project was to create one, containing ingredients on levels described by a customer. A product had been developed before, but resulted in a product that had viscosity that was too high, and the aim with this further development project was to keep the levels of the ingredients on a level according t
This thesis addresses a project conducted in collaboration with Volvo Car Corporation, to develop a new concept for luggage covers in car luggage compartments. The purpose was to find a new concept, with focus on user friendliness and environmental sustainability, which automatically opens up for easy loading of the luggage compartment. The fabric in today's solution is made of polyester and P
Stroke is one of the leading causes of death and the most common cause for disability among the adult population in Sweden, due in part to the fact that many patients do not arrive at the hospital in time for treatment. A system that could detect unilateral arm weakness based on arm movement, a common symptom of stroke, is therefore desirable. In recent years there has been rapid development in th
In today’s world of uncertainties, video surveillance is widely used to make the people of our society feel safe and protected. As more cameras are installed, the time of installation and ease of use play a critical role when customers decide which camera solution to select. One way to limit the number of cameras needed to cover multiple directions and large areas is to install a multidirectional
När hjärtat slutar slå och inte pumpar blod längre, kallas det för hjärtstopp. Det finns olika orsaker som leder till hjärtstopp så som underliggande hjärtsjukdomar eller ventrikelflimmer. Utan behandling dör patienter som har drabbats av hjärtstopp och även med behandling leder hjärtstopp ofta till död eller neurologiska problem. Målet med detta arbete är att dela in hjärtstoppspatienter i olikIn this thesis, it is analysed if cardiac arrest patients can be grouped into similar clusters based on different underlying conditions and clinical variables and if there is a difference between clusters in either mortality or neurological outcome as measured by the Cerebral Performance Categories (CPC) scale. The two data sets both contain a targeted temperature management variable which indicat
År 2018 ändrades reglerna för förmånsbeskattning av privatfinansierad vård som arbetsgivare betalar åt sina anställda. Tidigare var sådan vårdförmån inte skattepliktig för den anställde och icke avdragsgill för arbetsgivaren, men värdet ska nu tas upp till beskattning i inkomstslaget tjänst och istället är kostnaden avdragsgill för arbetsgivaren. Ett huvudsakligt argument för arbetsgivare att stå In 2018, the rules on taxation of private health care and health care insurances that employers pay to their employees were changed. Previously, such care was not to be taxed for the employee and non-deductible for the employer. The value of such service must now be included for taxation for the employee and is instead deductible for the employer. A major argument for employers to bear these costs
This paper examines the state of public transportation in the swedish county of Scania during the Covid-19 pandemic. Through travel statistics from the agency that runs the county’s transit network (Skånetrafiken) it is concluded that travel numbers have decreased dramatically during the pandemic. Two employees at Skånetrafiken are interviewed and asked about what measures the agency has taken dur
This paper examines the sufficiency of a trading method based on singular value decomposition (SVD) of past stock prices. The SVD method is frequently used as a tool to reduce data noise, compress big-data, and analyse data components. Hence, the method is well suited to form a ground for a predictive tool of price developments. From the predicted pattern, a strategy was formed by construction of
Advancements in today's technology has motivated invention of faster mobile communication systems. The fifth generation mobile network, 5G, is the latest version made by the third generation partnership project (3GPP) and expects to both increase connection speed and reduce latency, which eventually will make it applicable in supporting state-of-the art technologies such as virtual reality and
The combination of item non response and cluster analysis is a field which has not been explored to its full extent. This study aims to investigate which consequences a data set with missing values has on the algorithm of cluster analysis and which model for imputation should be suggested in order to minimize standard error and the optimal number of clusters. Basing our research on principal compo
Private set intersection is a technique for finding the intersection of (two) parties' sets without disclosing anything else, and it finds it use in e.g. contact discovery, finding friends who are already on a social platform. Multi-party threshold private set intersection is an extension of this which allows multiple parties and only reveals the intersection if the intersection is larger than
Biological pharmaceuticals are the answer to many severe diseases of today’s society. Some of these are protein-based drugs and can be produced from human blood plasma. In order to guarantee the safety of patients, absence of any pathogens needs to be ensured. Such a pathogen is HIV-1, which holds high mutation rate and a large variation in its genome. The aim of this project was to develop novel
The purpose of this study was to examine the thoughts and experiences of children’s investigators of the social services regarding the recent incorporation of the UN Convention on the Rights of the Child (UNCRC) into Swedish domestic law. By doing so we wished to gain a greater understanding of the practical implications of this new law. Our method was qualitative and the data collected through se
