How the brain processes all the incoming information it receives is still an unanswered question, and many different theories about how it is done exist. This thesis expands on one of these theories which views the brain's information processing as a widely distributed network phenomena, which contradicts the currently most popular hierarchical theory consisting of areas dedicated to processin
There are several accident investigation methods and they are used in a wide range of fields. However, the methods have not been used so much in the fire accident area. In the present thesis, the methods’ capability to investigate fires and what they result in are explored. In addition, answers are given concerning how important the background information is for their applicability. First, a selec
This report is a cost benefit analysis of a proposal for new sprinkler installation guidelines for ro-ro deck. It is a relative comparison between the present guidelines and a new proposal developed by SP Technical Research Institute of Sweden. The results and conclusions in this report are based on; data gathered from multiple water sprinkler tests, other relevant literature, experts’ judgment an
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
In 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 variablerna
The 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
