SAAB Dynamics produces and develops warheads and uses computer simulations to evaluate its products. Recently, SAAB has begun using neural networks to quickly obtain accurate outputs, based on simulated data, from a set of input variables with success. This thesis investigated whether interim data in the form of video frames can improve the output of the network. This thesis investigated the use o
Arbetet ämnar till att undersöka eventuella samband mellan fordonsdata och förseningsdata för att fastställa om fordonsdata kan användas för att förutse förseningar. Fordonsdata som genererats till följd av behov för kontrollundersökning, i.e. felkoder, har kombinerats med förseningsdata från Stockholms pendeltåg mellan 2017-01-01 och 2018-12-08. Statistiska beräkningsmetoder har använts för att a
Power consumption has become a leading concern for SoC aimed at 5G products that demand increased functionality, smaller form factors, and low energy footprint. For some EMCA IP blocks a hierarchical clock gating mechanism ensures coarse-grained power savings based on actual processing need but for many blocks this approach cannot be employed. This implies that these blocks have to rely on a high
Studies on several target factors like specific antigens, biomarkers and cellular signals involved in High-risk Human papilloma virus (HR-HPV) infection and its mediated immune response aid in narrowing the gap to generate effective therapeutic solutions for oropharyngeal carcinomas. Thus, establishing cytotoxic T-lymphocytes (CTL) lines will aid in investigating and carrying out functional studie
Batch high-shear mixers are used in a variety of different processing industries,such as the pharmaceutical, chemical and food industries. One company that utilize this type of mixers is Tetra Pak. High-shear mixers can be used for many different mixing scenarios, but only liquid-liquid mixing is discussed in the thesis. The batch high-shear mixer is constructed with a rotor-stator at the bottom o
Commercial finite element codes are designed with a wide variety of tools and options to suit the needs of many different applications. However, in a teaching setting this is not always desirable as the effort required to learn the software draws focus and time from the teaching of the theoretical concepts. Using fully developed solvers might also allow solving of exercises without fully understan
Today communication, promotion and transaction of products are key functions of product packaging. The quality of the package print is therefore of great importance and needs to be consistent for large production quantities. One of the most common technologies for printing on paper or cardboard is flexographic printing. With this technology colors are applied one by one and through their combinati
This thesis deals with the study of how the Smart Mirror fares compared to other information oriented devices in three areas: Energy consumption, light interference from the mirror foils and general performance of the computer system. The development of Smart Mirrors has mainly been focused on usability, whilst research in performance and light interference is lacking. The project, contains compos
The purpose of this thesis is to explore the motivations of young people for manifesting their consumption behavior through Instagram stories. Additionally, the purpose includes gaining an understanding of the way consumption behavior is portrayed.
En morfologisk analys av ett konstprojekt som bedrevs inom ramen för den ideella föreningen Ars & Modus verksamhet mellan 2004 – 2009. Utifrån analysen dras riktlinjer upp för en pedagogisk studie. Konstprojektet skrivs först in i ett större politiskt, ekonomiskt och konstnärligt sammanhang, där konstbegreppet utvecklas och problematiseras. Därefter belyses konstens alltmer instrumentella situA morphological analysis of an art project that was active during the years 2004 through 2009 within the framework of the NGO Ars & Modus. With this analysis as a starting point a study is then outlined. First the art project is put in a wider political, economic and artistic context and the concept ”art” is further developed and problematized. Then the growing instrumentalisation of art is hi
The aim of this master thesis was to develop adaptive control for a quadrotor using Gaussian process regression (GP). Online regression with GPs can provide many benefits as it is a flexible non-linear regression model that can provide uncertainty measures of the estimate. However, online GP regression may also gives rise to problems. Because of the high numerical complexity of GPs, sparse approxi
Knowledge about the gas-phase close to an active catalyst is essential in order to understand the properties of the catalytic reaction process. By the use of planar laser-induced fluorescence (PLIF), the gas-phase can be visualized with high spatial and temporal resolution without affecting the catalyst. In this work, catalytic CO oxidation over a Pd(100) catalyst is investigated using laser-induc
It is important to the recruitment company that only quality candidates, and the candidates most likely to receive an offer of employment get short-listed to go through the carriers selection process. It is this second phase of the recruitment process, the short-listing of potential candidates, that will be the focus of this thesis. Data has being gathered by the recruitment company through an i
Until year 2050 the world population will be increased with more than two billion people, this will lead to high demands of food supply. At the same time many of the worlds fish stocks are overfished or under a lot of pressure due to the environment. This study has investigated the pros and cons with recirculating aquacultursystems from the viewpoint’s energy use, carbon dioxide emissions and ethi
Syftet med examensarbetet är att undersöka möjligheten att presentera en kompositvy där den ena delen av vyn visar bilens omgiving, sett ur ett fågelperspektiv, och den andra visar bilens backkamera. För att undersöka denna möjlighet byggdes två prototyper baserade på två separata implementationer av parkeringskameran. Den första prototypen baseras på Volvo Car Corporations egen version av AndroidIn this thesis two prototypes, based on separate implementations of a Park Assist Camera, was developed. The purpose was to investigate the possibility of presenting a composite view, where the first view shows the surroundings of the car from a bird’s-eye view and the other view shows the rear camera. The first prototype was based on Volvo Car Corporations flavour of Android OS, where the perform
An ensemble Green's function theory for many-electron systems with degenerate ground states, based on the von Neumann density matrix formalism, is proposed. The formalism is constructed without an assumption of an adiabatic connection. An ensemble analogue of Hedin's equations and the GW Approximation (GWA) is constructed. The formalism is applied to four model systems within GWA: a three-
Problem – Even though existing research demonstrated why higher education and entrepreneurship are being pursued, it remained unclear what drives people towards studying entrepreneurship at university. Aim – The aim of this work was to integrate the literature streams of higher education and entrepreneurship by exploring the motives and environmental factors for choosing to study entrepreneurship
The Earth’s climate has always been changing, since the origin of our planet. The rate of change is now rapidly increasing in a substantial scale, leading to new challenges. The average temperature on Earth has risen 0.9 degrees since the 19th century and the oceans have absorbed a substantial amount of heat and carbon dioxide, believed leading to ocean acidification killing the marine life. Ice s
Physics-informed neural networks integrate physical laws into machine learning models to solve differential equations. This thesis investigates an inverse physics-informed neural network framework for estimating viscosity in Tetra Pak’s injection molding process, where direct measurements are not possible. By enforcing the Navier-Stokes equations and using sparse velocity and pressure data, a virt
To be able to meet the global energy demands, a steady supply of green energy is required, even during sun- or windless hours. Concentrated solar power is a useful alternative, which can produce and store green energy by heating a heat transfer fluid (HTF) and extracting its energy via a heat exchanger. One such category of HTF is molten salts, and to understand and be able to model the behaviour
