Threat and Error Management (TEM) har framförts som en modell för att förstå, förklara och utbilda i hur olika flygsäkerhetsrisker uppkommer och kan hanteras för att uppnå en ökad flygsäkerhet. Den bygger till stor del på den tidigare utvecklade modellen för övervakning av operationell flygverksamhet, Line Operations Safety Audit (LOSA). Information har insamlats med hjälp av litteraturstudier, in
Modern embedded development flows often depend on FPGA board usage for pre-ASIC system verification. The purpose of this project is to instead explore the usage of Electronic System Level (ESL) hardware-software co-simulation through the usage of ARM SoC Designer tool to create a virtual prototype of a cellular IoT modem and thereafter compare the benefits of including such a methodology into the
Eutrophication caused by nutrients such as phosphorus has become a major issue over the years. Dealing with this phenomenon is a major concern in many countries, and municipalities are establishing strict rules to cope with this problem in water bodies. However, the development of cities has a cost, and supplying the food needs of people is essential. In order to optimize agricultural lands, the u
Interactions between T-cells and other body cells is an essential part of the immune system. It involves the binding between surface receptors of the two cells. Specifically, T-cell receptors (TCRs) bind onto pMHC (peptide-loaded major histocompatibility complex) molecules on the partnering cell surface. This way, a cell signal from the TCR to the nucleus can be initiated. Depending on the "m
With socio-economic hardships arising and dramatically worsening as a cause of the present-day financial crisis, The World Bank has warned against severe cases of brain drain as emigration becomes increasingly desirable to the Lebanese population. Lebanon, already possessing one of the world’s largest diaspora, can be characterized as being one of the largest remittance-receiving countries, where
Vital societal functions and critical infrastructure rely to an increasing extent on services from space, such as navigation and positioning systems, timekeeping, and communications. However, understanding of space service dependencies is low among practitioners and society at large, with research on societal space dependency being limited as well. In order to avoid cascading effects from disrupti
Danske Bank has for several years modeled customer purchase behavior on category level (e.g. savings or investments). This thesis is a first attempt at predicting (first time) customer purchase behavior on product level. Five products within two categories were chosen and modelling was done with python using gradient boosters (mainly XGBoost, but also Light GBM). Results indicated that predicting
Of the food produced for human consumption, one-third is lost or wasted. Food waste has an impact on the environment in several ways and it is thus required to reduce food waste in all parts of the value chain. The objective of this thesis is to identify drivers and barriers for implementing food waste reducing strategies in school kitchens. The study is conducted within the project Göteborgsmod
Temperature recordings from a moving vehicle are frequently used in microclimatological research. This work aims at investigating three aspects of the quality and the representability of mobile-recorded temperature data: the displacement of air near the car's front; the inertia of the sensors which hinders the accurate recording of fast fluctuations, and how good temperature profiles obtained
The problem of increasing population is quite an old topic. The main aim of the study is to investigate the relationship between population and economic growth in Japan and Singapore in the period between the 1960s and 2000s. This is to be done using theoretical framework involving theories of economic growth, as well as structural and demographic change theories. The study indicates a positiv
The main aim of this project was to peel off the epitaxially grown nanowires (NWs) from their native substrate and transfer them to the cheaper carrier substrate in order to make solar cell device from transferred NWs. Potentially the peeling and transferring idea is about to decrease the cost of NWs growth by reusing the native substrate especially for expensive material such as InP and GaAs whic
This thesis aims to identify online branding channels used by SMEs and determine which of those channels are the most effective. For this, a quantitative study of four SME brands is conducted and their online branding efforts analyzed. The findings add to the existing theory in the field as well as propose a new framework for analyzing and classifying SMEs online branding channels. The gathered da
Sammanfattning Den här uppsatsen är en granskning av brittisk, svensk och kanadensisk upphovsrätt. Mer exakt utreder detta arbete de olika ländernas syn på parodier och hur dessa skyddas under respektive lands upphovsrättslag. För att få en bättre förståelse för om parodier kan kvalificeras som upphovsrättsliga verk, berör även denna uppsats vilka olika kriterier varje land har satt upp för att Summary This paper examines the copyright laws of the British, Swedish and Canadian systems. More precisely it investigates the different countries views on parodies and in what way they are or aren’t protected under their Copyright Act. To get a better understanding of parodies and how they can qualify as a copyright work, this paper also deals with the different requirement each country has set
The goal of this master thesis was to examine some of the available development tools for augmented reality in mobile applications. The best development tool were then used in development of an application for Android or iOS. The thesis has two main parts, the analysis of development tools and the application development. During the analysis ve dierent commercial development tools for augmented re
The possibility to print out metallic components with complex 3D-structures is could revolutionize the industry. In this master’s thesis the cause of process parameters have been investigated for three alloys; stainless steel, 316L, two nickel-based alloys, a derivative of Alloy 738 and 939. Microstructure, porosity, tensile testing, impact toughness, hardness and surface roughness was investigate
Value-at-Risk (VaR) forecasting in the context of Monte Carlo simulations is evaluated. A range of parametric models is considered, namely the traditional Generalized Autore- gressive Conditional Heteroscedasticity (GARCH) model, the exponential GARCH and the GJR-GARCH, which are put in the context of the Gaussian and Student-t distri- butions. The returns of the S&P 500 provide the basis for
This study gives an insight how new technology-based-firms (NTBFs) take part in investment readiness programmes (IRP) in practice and how this differs from the theoretical model by Mason and Harrison (2001). The first part of this study focuses on NTBFs, the role the play in the economy, the challenges they face and their need for financial resources. Furthermore, this paper explains the theoretic
This master thesis is on Statistical Process Control (SPC). The objective is to evaluate if SPC can be used in a process that produces plates for heat exchanger, the process evaluated is located at Alfa Laval Lund AB. The products are produced in the process by punching and shearing metal coils. An ambition in the project is also to increase the knowledge about Statistical Process Control at Alfa
