The report studies the area of positive pressure ventilation, how it can be used to obtain a more effective fire services intervention and how an incorrect initiation could drastically worsen the interior conditions for occupants inclusive of fire services personnel. The tests in the report examine how flow rate and pressure within a building are affected if parameters such as fan placement and ra

This master’s thesis has been carried out in collaboration with the dynamic, acoustic and tribology simulation group in the engine development department at Scania CV in Södertälje, Sweden. When simulating tribological conjunctions, such as a journal bearing, it is often necessary to take the surface topography of the two bearing surfaces into account. The surface topography can influence the hydr

China has experienced an exceptional amount of privatization, market liberalization and reform in the last forty years. With these changes in China’s economy and the strategy of using labour as its comparative advantage, it is of paramount importance to the development field, to investigate how these changes in the market have affected management approaches and their subsequent labour conditions.

This essay examines how eight identified negative effects influence the perceived motivation and performance of employees as a result of the current efficacious monetary incentive system. Through a multiple case study based on a qualitative research method, eight semi-structured were conducted. Afterwards the interviews were compiled in a database and analyzed. Both an inductive and deductive ap

Bilateral Investment Treaty is an agreement designed to increase FDI between signatories. Historically the treaty is concluded between a developed country and a developing country, as a risk-lowering instrument. In recent years agreements carried out between developed countries has put more focus on investments and adopted contents of a BIT, examples of this is TTIP, TPP and CETA. Yet there is lit

The Swedish Sea Rescue Society (SSRS) currently does not have a convenient and intuitive solution for the at sea communication. Today there are several helmets and radio devices tried to fulfill their needs but neither of them has succeeded to work well as a system. Through both primary research (Interviewing coastguards and other SSRS staff, field trips to rescue stations, trying out existing ge

We are a team of Environmental Management and Policy Master’s students at the International Institute for Industrial Environmental Economics (IIIEE), Lund University, Sweden. As part of our Strategic Environmental Development course we were invited by Madam Mayor of Zabrze, Ms. Małgorzata Mańka-Szulik, to develop a framework for a sustainable mobility strategy for the city of Zabrze. Zabrze is loc

Modelica is a declarative object-oriented language for describing mathematical models. Modelica models are used for simulation and optimization of systems and processes. The models are described using variables and equations. It is possible to associate units of measurement to variables, for example, variable x is in m/s. This thesis presents a way to analyze units in equations to find errors. Thi

Klassificering av pennor av olika material till touch-skärm Genom att koppla en kontaktmikrofon till en touchskärm och undersöka de vibrationsmönster som uppstår då olika objekt rör vid skärmen har en dator tränats till att känna igen olika typer av material. Om en filt och en träpenna användes kunde datorn känna skillnad på vilket material som användes i mer än 99,5% av fallen. Resultatet av proIn this report, a potential improvement of an optical touch screen solution by means of acoustic sensing is presented. The goal is to utilize the different vibration patterns that arise when different materials touch the screen to be able to identify them. This identification of different materials opens up new opportunities to give input to the touch-device which could potentially replace menu ba

Examining the relation between Swedish households’ debt, property price and interest rates are important when forming monetary policy implications. Several studies have examined the driving factors of household debt and property price, however the results are inconclusive. This thesis differs from previous research as it includes the variable interest to income ratio, instead of debt ratio, as the

The immigrants from China have generally taken over European immigrants to play important role in the North America since 1960s. Based on the human capital theory and neoclassical economic theory, this thesis examines the characteristics of Chinese immigrants who respectively arrived at the United States and Canada since 1990 (cohort 1990-1997 and cohort 1998- 2000). The data is coming from the 20

NTRU is a public-key cryptosystem, where the underlying mathematical problem is currently safe against large-scale quantum computer attacks. The system is not as well investigated, as for example RSA, and the company behind NTRU has created the NTRU Challenges, to remedy this. These challenges consist of 27 different public keys of increasing size, where the task in each challenge is to calculate

I denna uppsats har en ekonometrisk analys utförts för att undersöka räntans effekt på konsumtionen i Sverige mellan åren 1995-2016. En del av fokusen har legat på de låga räntenivåerna sedan 2009 och den rådande negativa reporäntan. I modellen har även ytterligare makroekonomiska variabler inkluderats för att undersöka vad som har en märkbar effekt på konsumtionen. Enligt resultat har variablernaIn this essay an econometric analysis have been done to investigate and evaluate the steering interest rate effect on consumption in Sweden between the years 1995-2016. Parts of the focus of this essay has been on the low rate levels since 2009, and the current negative rate. In the econometric model, additional macroeconomic variables have been included, in order to investigate what affects consu

Tanken att beskriva världen utifrån dess minsta beståndsdelar har levt ibland oss ända sedan Demokritos leverne. Det dröjde dock drygt 2300 år innan mänskligheten nådde en någorlunda tillfredställande teori för att förklara elementarpartiklarnas egenskaper och interaktioner, den så kallade Standardmodellen. Sedan dess har jakten efter en mer allmängiltig teori pågått. Denna uppsats behandlar en sThe thesis treats the construction of a supersymmetric model, inspired by an E8 unfication scenario. Via the introduction of adjoint representation chiral superfields, in combination with the inclusion of a global generation symmetry, the Standard Model fermion candidates are protected from gaining any mass until electroweak symmetry breaking. In addition, an accidental global baryon symmetry proh

Sydvatten AB is a municipally owned company producing and supplying drinking water to about 900,000 inhabitants in southern Sweden through two water treatment plants (WTP), Ringsjöverket and Vombverket. At Vombverket, the present capacity is somewhat reduced because of pressure losses in the pipe systems of the WTP. Parts of the WTP was built already in the 1950’s and it was significantly expande

Abstract Recent financial crises have demonstrated the importance of accurately measuring financial risks in order to be able to employ mitigating risk policies. This essay investigates the question whether a GARCH model augmented by an autoregressive conditional jump intensity component can improve value-at-risk forecasts in comparison to common GARCH models. Therefore, the VaR forecasting perfor
