Den här uppsatsen utreder möjligheten att använda en modell som skattats med tidsserieanalys i Konjunkturinstitutets (KI) prognoser på offentlig konsumtion. Autoregressiva modeller skattas på realtidsdata från 1994. Modellerna skattas och utvärderas med out-of-sample prognoser. Modellernas prognosförmåga utvärderas mot första publiceringen av statistik för offentlig konsumtion för perioden 2004–20
In today’s competitive vehicle industry, fuel efficiency and weight plays a crucial role in performance and to maintain an attractive market position. The increasing technological development is opening new possibilities to design components with lighter materials. All components on Scania buses are favorably designed with as low weight as possible since the measured load on the back axis determin
The aim of this paper is to present the kinds of error that implicit bias can cause when we are to judge and rank which available candidate is the most suited for e. g. a job vacancy, and to investigate whether we can de-bias ranking lists in recruiting processes given that we suspect that implicit bias has influenced the ranking. I will argue that the available methods for this (positive discrimi
The North Sea stands out as one of the most rapidly warming regions of the globe and various types of geographic distribution responses have already been reported, from latitudinal changes to vertical changes. Using catch data from an international bottom trawling monitoring survey, this study investigated how the range size of the North Sea fish assemblage has changed during the last three decade
As the development of human civilizations, the classic definition of crowdedness index or population density is not able to describe population dynamic conciliations properly. Furthermore, the detailed population information is normally only stay on urban or country levels. Methods to compute crowdedness index of a small scale-area are lacked. Demographers need some new methods to compute human cr
The harbour porpoise (Phocoena phocoena) is the only cetacean regularly found in Swedish waters. Little is known about its movements and behaviour. Around the peninsula of Kullaberg, harbour porpoises are regularly found in relatively large numbers and they are considered to use the area for both feeding and reproduction. Along the northern coast of Kullaberg six passive acoustic data loggers; Cet
Syftet med denna studie är att undersöka vad som får elever att börja spela brassinstrument och vilka faktorer som motiverar dem till att fortsätta på Musik- och Kulturskolan. Bakgrunden till studien är att antalet elever på brassinstrumenten i Musik- och Kulturskolorna har minskat i Sverige under lång tid. Data består av gruppintervjuer med 11 elever i tre åldersbaserade grupper. Resultatet viThe purpose of this study is to investigate what motivates students to begin playing a brass instrument and the factors that motivate them to continue in the Community School of Music and Arts. The background for this study is that the number of students on brass instruments in the Community Schools of Music and Arts in Sweden has been decreasing for many years. Data collection was performed thro
Det proportionella valsättet bygger på tanken om en samförståndsmodell där olika intressen representeras efter sin storlek, att besluten växer fram efter förhandlingar och att man överbryggar klyftan mellan majoritet och minoritet. Det proportionella valsättet är således ett minoritetsskydd som tillförsäkrar även de mindre politiska partierna rätt till förtroendeposter och därmed makt och insyn.
Type 1 Diabetes (T1D) is an immune-mediated disease where the pancreatic beta cells are selectively destroyed by autoreactive CD8+ T cells. However, the triggering events that eventually leads to autoreactive CD8 T cells infiltrating the pancreatic islets and, subsequently, destroying them still needs to be unveiled. Genetic and epidemiological evidence points to a substantial influence of environ
Map design research has strongly come into the agenda with the extensive use of GIS and maps in geoportals. Geoportals are used to find, access and display geographic data via the Internet. Novel opportunities and techniques for displaying geographic data in viewing services also introduce new challenges and issues in cartographic design. Specifically, thematic polygon layers (foreground) will obs
The thesis deals with how to price swing options in the electricity market by using a least squares Monte Carlo method. This is a simulation method which uses a backwards moving algorithm where the optimal decision is calculated at every time step. Regression is used for the optimal decision and in this thesis both a polynomial regression and a cubic smoothing spline are used. They are both shown
I undersökningen ”Fokus på förskolläraruppdraget” har jag undersökt hur förskollärarna uppfatar sitt uppdrag samt hur de omsätter uppdraget i praktiken. Jag har även undersökt vilken påverkan kommunikationen har för förskollärare i deras uppdrag. Jag har avgränsat mig till att samtala med förskollärarna eftersom de har det yttersta pedagogiska an-svaret för verksamheten. Undersökningen är en kvali
This thesis considers quantitative tools for assessing concentration risks in credit portfolios that may underlie decision making in an active portfolio management setting. The study incorporates a literature review, which considers analytical and simulation based credit risk models in a Merton-type framework as well as aspects of credit portfolio management. The literature review is followed by a
Bushfire problem is a long-lasting problem which is a big threat and environmental problem in Australia. Planning to control bushfire is very important for Australian Environment. One of the most effective methods to fight bushfire disasters is planning for controlled burns in order to reduce the risk of unwanted bushfire events. Controlled burns management and planning has been always considered
The use of Islamic symbols in metal music has, until now, been a rare phenomenon. A few years ago, some black metal-bands in Istanbul started using Islamic symbols in both their artwork and lyrics, often in an anti-Islamic fashion. Although research on metal music is well established, little has been done on the relationship between black metal and Islam. This thesis explores the relationship betw
This paper investigates how the adaptation of the new regulations of Base III will affect the banking industry and how the theoretical framework around charter value hypothesis can explain these changes. The empirical study has been based on performance analysis of four major European banks with the purpose of identifying the impact of the new regulations on their finances. The data used for this
Enzymatic pretreatment of algae – by means of cellulose degrading enzyme – was evaluated through lab-scale and pilot-scale experiments. The degradation efficiency of the enzyme depended on the initial physical quality of the algae. Lab-scale batch anaerobic digestion experiments showed comparatively low methane potential for the pretreated algae at both mesophilic and thermophilic temperatures. Ho
Nowadays, urbanization is expanding over natural habitats, imposing changes on animal communities. Cities provide abundant supplementary food, but its nutritional are different from what birds can find in nature, for instance in the content of fatty acids (FAs). FAs fulfil important physiological functions, being essential in a multitude of processes throughout the life of animals. However, FAs ar
It is well-known that long memory and regime switching in the first moment of a stochastic process are easily confused. But the relation between long memory in the second moment and regime switching in the second moment is less well understood. We perform a simulation study in which we assess the possibility to distinguish the two properties in the case that data with long memory in the second mom
This master’s thesis project report deals with the design of multiplier for the reference signal to the Phase Locked Loop (PLL) used in WLAN application. The reference multiplier designed is based on a newly proposed architecture of dual loop feedback Delay Locked Loop (DLL) in which multiplication is performed within the loops. To lock the DLL, input signal is required to be delayed only for thre
