I detta arbete studeras minsta kvadratmetoden för identifiering av en linjär samplad modell med en insignal och en utsignal. Speciellt har frågan om modellens ordningstal studerats. En numerisk algoritm, som iterativt anpassar modeller med växande ordningstal, har således utvecklats. För att bestämma modellens ordningstal användes statistisk hypotesprövning. Den klassiska F-testen, som utvecklats

Det problem, som skall behandlas här, ligger inom det område av regleringtekniken, som kallas optimeringteori. Detta är ett mycket vidsträckt område med stor praktisk betydelse. Det gäller ju ofta att maximera eller minimera en viss storhet, och detta oftast då samtidigt som vi måste införa begränsningar av olika slag för andra storheter.
Optimala styrningsproblem uppkommer i samband med proce

I denna uppsats genomförs en kritisk granskning av kriminaliseringen av olaga förföljelse som infördes i brottsbalken år 2011. Granskningen görs främst i förhållande till den straffrättsliga preventionsteorin, men även gentemot de kriterier för kriminalisering som formulerat i doktrin och förarbeten. Straffrättssystemets syfte är främst att påverka medborgarna att avhålla sig från oönskade gärninIn this essay I conduct a critical review of the criminalisation of the crime ”illegal persecution” which was included in the Swedish penal code in 2011. The review is made first and foremost in the light of the criminal law theory of the criminal system as preemptive, bur also in the light of the criminalisation criteria which has been formulated both in the criminal doctrine, and in the legislat

In a recent experiment, the partial half-life (t1/2) of proton emission from the Iπ = 19/2- state of 53Co was accurately measured. A previous estimate is t1/2 ~ 17 s. The purpose of this thesis was to explain this decay and give a theoretical estimate for the dominating hindrance factors. The angular momentum J in 53Co is coupled to J = 6 for the neutrons, and J = 7/2 for the protons. All of this

The purpose of this qualitative study, with a constructivist approach, was to examine how professionals work with children as next of kin to chronically ill patients in somatic care. Through a content analysis, using local guidelines and policy documents for the work with children as next of kin, as well as semi-structured interviews focusing on how the professionals themselves describe their

The study examined social workers experiences in their work with adolescents in out-of-home care, focused on sexuality. The aim of the study was to understand their experiences with a constructionist perspective on sexuality and with a focus on the organizational context that the experiences were formed in. These perspectives were selected with the ambition to achieve an extensive view of the stud

This study aims at investigating the thematic patterns in media presentations of Swedish communal social services and the social service workers: how is the media discussion created and established? Which areas are paid the main attention? How is the field being portrayed in media? The study is based on a material found in Swedish newspapers published under a three-month period in the end of 2014.

This master thesis investigates material characterization by reflection and transmission of electromagnetic waves in the 40-60 GHz band (millimeter-wave spectrum) for different materials. The free-space measurement method is a fast, efficient and non-destructive way of examining a material and is being researched by both academics and industries. The theory of how electromagnetic waves interact w
