The thesis is done for the company Gambro which manufactures dialysis products worldwide. The idea of this thesis is to investigate weaknesses of the communication protocol which is used in one of the Gambro dialysis machines, Prismaflex and thereby investigate opportunities to improve the system by using other protocols. The thesis is divided into three major parts. They are the study of Prismafl
The aim of this thesis is to investigate the factors hindering and enabling the use of the environmental composite indicator, the Ecological Footprint, in Denmark. In this project, Actor-network theory and case study research will be applied to the empirical material, consisting of five semi-structured interviews and written documents. The case study approach works as a general research strategy,
The purpose of this report is to evaluate the current fire hazards and evacuation safety on board the M/S Hansa in Helsingborg. The report is a part of the course, VBR054, Fire safety evaluation. The main goal of this report is to study the safety of people evacuating the building, therefore damage to property and structural stability has not been evaluated. M/S Hansa was originally built as a pas
På grund av svåra metodologiska och praktiska svårigheter domineras forskning om bolagsstyrning i allmänhet och styrelseeffektivitet i synnerhet av relativt ytliga modeller. Så kallade black boxstudier är mycket vanliga, och kontrasteras mest av rent konceptuella modeller utan kvantitativa amibitioner. Den här uppsatsen kikar in i den svarta lådan och utforskar den interpersonella kontexten i styrDue to severe methodological and practical difficulties, research on corporate governance in general and board performance in particular is dominated by relatively shallow models. So called black box studies are very common, and are contrasted mainly by conceptual models without any quantitative ambitions. This paper peeks into the black box, exploring the interpersonal context within the board ro
Flygprestanda AB supplies IT services for airline operations, management and control. The system delivered to facilitate this is the Flight Operation Control System or FOCS. This thesis addresses the Schedule View service included in the FOCS system. The Schedule View is a tool where the user gets an overview of aircrafts and planned flights. In addition aircrafts and flights can be added and modi
Gehörsundervisning är ofta obligatoriskt i musikutbildningar. Trots att många moment inom gehörsundervisning, såsom prima vista-sång, kräver en mängd kognitiva färdigheter visar tidigare forskning att den kognitiva sidan av gehör sällan behandlas inom musikpedagogiken. I studien analyseras forskningsresultat från musikpedagogik och mer kognitionsinriktad forskning för att undersöka i vad mån resul
Forskning har kunnat visa att aktiv framplockning av tidigare inlärda minnen kan hämma framplockning av konkurrerande minnen vilket leder till en framplockningsinducerad glömska, kallad retrieval-induced forgetting, RIF. Denna form av glömska tillskrivs ofta en kognitivt inhiberande process som aktiveras för att försvåra framplockning av icke relevanta konkurrerande minnen till förmån för underlätResearch has shown that active retrieval of previously learned memories can diminish retrieval of other concurring memories leading to what is known as retrieval-induced forgetting, RIF. This form of forgetting is often ascribed to a cognitive inhibition-process thought to be activated to reduce retrieval of not relevant concurring memories in favour of retrieval of sought after memories.

In this thesis, functions describing relations between chemical concentrations at equilibrium are studied. The functions have some parameters that are desired to be determined. Based on the properties of the functions, an optimization method will be proposed. Because of these special properties, it is appropriate to consider the residuals in the max norm, since then it is possible to show that the
The microbial community in five commercial Pu-erh tea products and one Liu Bao Cha tea were investigated in this study with the aim to search for beneficial live bacteria. Three different treatments were applied for every tea; non-brewed, brewed with and without leaf filtration. The results showed microbial activity in all teas and particularly lactic acid bacteria (LAB), except in the Liu Bao Cha
Consider n vertices arranged in a circle where each vertex is given a fitness from {0,1}. At each discrete time step, one of the vertices with fitness equal to zero (unless there are none of those, then pick a vertex with fitness equal to one) is selected with equal probability. Then this vertex and the two neighbouring vertices are each given a new fitness from a Bernoulli(p) distribution indepen
Today the word identity is filled with many different contents. Depending from which perspective one tries to examine a scientific research-question, there is a variety of interpretations of the problem. In this thesis the aim is to prove with help of postmodernist theory how the Swedish identity was built by the articulation of difference towards the other over decades. The analysis is conducted
The main characteristic of the Clean Development Mechanism (CDM) introduced by the Kyoto Protocol is its twofold objective, aimed at integrating the goal of reducing CO2 emissions, on a local and global scale, with the promotion of sustainable development in developing countries. This work discusses how sustainability assessment at the project level remains a critical issue, as it is often regarde
In this thesis I examine the development and expansion of judicial power in Sweden. The concept of judicial review is defined and related to democratic theory, and the various forms of judicial review in use in Sweden are explained. The main focus is on the political and scientific discussion concerning judicial review since the mid 1970s. It is shown that judicial review so far has been used only
In certain types of glulam roof structures with large spans, reliable methods for design with respect to instability are lacking. One example is a three-hinged roof truss with steel tension rods as shown in Figure 1. The types of structures shown in Figure 1 are investigated in the diploma project with the purpose to evaluate and improve the currently used design methods and detailing. Calculation
This report focuses on CFD-calculations using parallel processors carried out with the software Fire Dynamics Simulator (FDS). From a users point of view the advantages and disadvantages with parallel CFD-calculations were analyzed and evaluated. A simplified me-thod for quantitative evaluation was developed with guidance from ASTM E 1355 whereu-pon relative differences between serial reference sc
