Sensing temperature is important for identifying preferable temperatures and avoiding dangerous extremes. The cold pain limit of mammals in general is estimated to approximately 12 °C. I reasoned that such a skin temperature is unlikely to be sustainable in colder climates and studied cold-adapted dogs in northern Sweden using thermography. Skin temperature on the rhinarium (naked nose tip) was 2.
In the recent decade, European populist radical right parties have gained stronger position in politics, which is seen in both stronger voter support but also in greater legitimacy and increased political influence. However, there are differences between the newer and older member states of the European Union. Among the Eastern countries, who joined the union in 2004 or 2007, there are fewer succe
In 2013 the conservative ruling party of Spain, Partido Popular, launched a draft to a new Citizen Security Law that after a year of critical debate was rammed by the congress. The opponents claim that the laws are undermining democratic rights such as freedom of assembly and freedom of speech. Partido Popular defends the laws with reference to security and safety while opponents claim that the un
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
By using Axis pan/tilt/zoom cameras it is possible to create a simple, high quality video conference system, without the need for a separate computer to control the system. This can be achieved by connecting the camera to a standard television set and utilize open standards like the HDMI feature Con- sumer Electronics Control (CEC). With CEC it should be possible to control the system using a stan
Theoretically the relation between returns and idiosyncratic volatility should be non-existent or positive. Many empirical studies confirm this but Ang, Hodrick, Xing and Zhang (2006) contest the conventional view and find a negative relationship for a sample of U.S. firms. I contribute to the field by investigating the relation for a sample of U.S. mutual funds. The sample consist of a total of 1
This thesis studies the use of GIS applications to derive adjustment figures for the terrain factor in property valuation tasks. It aims at suggesting a quantitative approach alternative to evaluate the terrain factor as opposed to traditional methods and current industry practices where terrain is qualitatively judged based on visual observation at site and subjected to individual opinion. In th
The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a
This thesis evaluates whether it is possible to use conjunctural indices from Statistics Sweden (Statistiska Centralbyrån) in order to improve the sales predictions at a Swedish gas company. For this purpose sales data for three of the main gases are gathered from the year 1995 and forth. In the first step, this data is used to create ARX and State Space models. Sales predictions are made from the
The Volvo Group has an ambitious plan to efficiencies its construction equipment vehicles with an introduction of a hybrid engine. This Master thesis is based on, as a first approach, to control the energy split in a hybrid construction equipment vehicle (HCEV) with the control strategy Model Predictive Control (MPC). The work is divided into two main parts, where the first one is to create a piec
Friction is present in all mechanical systems and causes a wide range of problems for control. The development of friction models and methods to account for friction in control has been an active research area for many years. A promising friction model that is capable of describing a wide array of observed friction phenomena is the LuGre model. This thesis deals with the application of friction co
In a wireless communication system, the channel is ever changing due to multipath properties such as excess delays and constructive and destructive interference. In a step to optimize system performance, it would be beneficial to have access to channel state information of both present subchannels' future development and subchannels outside the currently used frequency interval. In this thesis
The demand of today for advanced manufactured parts with high precision is due to the increasing complexity of technologies. The parts are typically made by CNC (Computer Numerical Control) machines, which are expensive and comparably big. By using industrial robots that are significantly cheaper, reduced costs can be achieved, which is particularly beneficial for small and medium enterprises. Rob
Bakgrund: Tilliten för livsmedelsbranschen och således köttbranschen har blivit ifrågasatt av konsumenter de senaste årtiondena på grund av olika redlighetsfusk, sjukdomsutbrott och misskötta djur. Konsumenter värderar kvalitetsattribut som säkerhet och etiska aspekter allt mer. Bevis som stödjer dessa värderingar kallas tillitsattribut, dessa går inte att utvärdera ens efter konsumtion. För köttb
Abstract Authors: Frida Ljungsten, Sara Sandberg Titel: Victim of a human perpetrator – a qualitative content analysis of judicial decisions. Supervisor: Roberto Scaramuzzino Examiner: Anett Schenk It is not unusual today that one will find articles about crimes of rape in the Swedish media. These articles are often expressing a doubt against how the court of law sentences the offender or descr
In this study we investigate the impact of the lowering of the payroll taxes in Sweden, in 2007 and 2009. A fixed effect OLS model is used to evaluate the effects. The model estimates the effects of the payroll tax cut in five different regions between 2001 – 2011. The general results from the estimations show that the payroll tax cut did create jobs however the effect was small and the reform was
