This master thesis explores the feasibility of using genetic algorithms in order to automate the process of optimizing hyperparameters for artificial neural networks (ANN). Today there is no standard way to optimize hyperparameters for ANN; often they are set manually by trial and error. In order to explore the feasibility of using genetic algorithms to optimize hyperparameters for ANN, two algori
Riskområden med snabb föroreningsspridning via grundvatten – grafisk illustration i ArcGIS Enskilda avlopp utpekas allt oftare som en betydande källa till spridning av förorenande substanser och patogener. Hur kan man identifiera och visualisera transporttider för föroreningar baserat på ett områdes geologiska karaktär? Idag finns cirka 700 000 hushåll med enskilt avlopp i Sverige varav hälften The raw water source lake Vombsjön is situated in the center of southern Scania and provides drinking water by artificial groundwater recharge for approximately 450 000 inhabitants each day. More than 2800 households within the catchment of lake Vombsjön treats their domestic wastewater with a decentralized sewer system. The configuration of these sewer systems varies, but it is common to have som
In ADB Safegate's airfield lighting product portfolio, two sizes of LED inset luminaires consist of similar internal components with different design. This project has investigated the possibilities to find generic design solutions for the internal components to fit both product sizes. By using modularized components the company will decrease the indirect costs of the product, for instance cos
The term Female Genital Mutilation is often used to describe a process whereby a part or all of the external female genitalia is been cut as a result of factors generally embedded around culture and tradition. This study takes a panoramic view at FGM beginning from a historical perspective when the practice was generally regarded as a cure to the sexual “excesses” of the female to the present day
Vad har kroppen för betydelse vid musikaliskt lärande? I en samhällsstruktur och akademisk tradition, där kroppen mer betraktas som ett transportmedel än som bärare av reell kunskap, ställs frågan i motvind. Denna studie ämnar i första hand undersöka idéstrukturer som omger vår syn på kroppens betydelse för och relation till musikaliskt lärande. Studien är inriktad på att via ett explorativt och What importance does the body hold in a musical learning experience? In a social structure and academic tradition, in which the body is more considered as a means of transport rather than as bearer of real knowledge, the question faces a headwind. This study mainly aims to investigate the preconceptions surrounding our view of the body's relevance and connection to musical learning experiences
The aim of the thesis is to analyse the current role of management accountants, how it is affected by contextual factors, and how it has changed over time. A quantitative content analysis of job advertisements is conducted. The factors of analysis are identified based on a combination of deductive and inductive approach. First, reporting, planning, budgeting, forecasting, cost accounting, MS Offi
Thesis Purpose The purpose of this research is to increase the understanding of occupational gender segregation by exploring how preschool teachers and principals perceive gender diversity, what they consider to be the primary issues that hinder men from entering this profession, and what they think a larger inclusion of men in the profession could lead to. Theoretical Perspective We based our re
The Jordanian state apparatus is increasingly limiting civil society in Jordan from engaging in open debate, and organisations are gradually inhibited from executing their activities and events. These are the premises on which this research is based, and in exploring them several questions arise. How can civil society in Jordan be characterised and applied? What do these obstacles look like in pra
Research Purpose: To explore the understandings of workplace inclusion through indepth investigation of the concept in an organizational context. Research Question: How do employees in Microsoft Denmark understand workplace inclusion? Methodology: Following an interpretive paradigm, we seek to explore in-depth understandings of employees in our case company. We conducted a multi-method qualitati
Säkerhet ses oftast som en del av en teknisk lösning vilket gör att företag har en tendens att dedicera mer resurser till teknisk säkerhet, snarare än strategisk säkerhet. Mänskliga faktorer kan ha en avgörande negativ roll för informationssäkerheten inom företag om grunden till informationssäkerheten inte hanteras på rätt sätt. Uppsatsen undersöker kopplingen mellan modellen CIA-triadens olika de
Language learning strategies are presented in several parts of the Swedish national syllabus for English for high school and teachers are expected to both teach learning strategies and to test and grade students’ use of them. Despite supporting documents, teachers have expressed an insecurity regarding what in the Swedish national syllabus for English is referred to as “[…] strategies to assimilat
Today energy supply is moving towards more renewable, which brings challenges to the power grid. Intermittent power is difficult to predict and cannot be regulated in the same way as conventional power. If the grid is not dimensioned to handle the power peaks, the intermittent power can cause overload on the grid. Overload causes larger losses, can damage electrical components in the grid and/or a
The main purpose of this thesis is to give a basic understanding of the GMV portfolio theory and the problematics that arise when using the sample covariance matrix as the only parameter. The reason for this is the amount of estimation error that tends to increase as the sample covariance matrix goes to a higher dimension. In an attempt to reduce the amount of error, an alternative approach based
This bachelor thesis is a critical policy analysis of two legislative proposals, L155 and L158, currently debated in the Danish Parliament. The proposals concern security measures for the potential extraction of uranium and other raw materials in Greenland. The aim of the paper is to examine the premises of the mentioned discussion and thereby derive knowledge about the current power relations bet
The purpose of this study is to investigate the feasibility of both online and offline fault location and state of health technologies for airport series circuits used to provide power to light fixtures on the runway. In current series circuits, only some ground faults can be detected and no automated fault location or state of health features are available. Fault location is currently performed w
Using derivative securities can help investors increase their expected returns as well as minimize their exposure to risk. For a risk-averse investor, options can offer both insurance and leverage and for a more risk-loving investor they can be used as speculation. Basket option is a kind of option whose payoff de- pends on an arbitrary portfolio of assets. The basket is made out of a weighted sum
This report is about further development of a test rig called the Delhi Metro Rail Corporation Test Rig, called the DMRC Test Rig. A method for testing pneumatic valves,used in the systems for train brakes and called brake valves, was developed.The main objective was to automatize the testing of all existing and future developed pneumatic brake valves, made by the company Faiveley Transport, using
Evaluating evacuation experiments is a time consuming work. This report explores the possibilities of an automated time saving procedure with the help of ordinary computer programs and video cameras. Simplifying the procedure means that more types of tests can be made, i.e. walking paths of people turning corners. Trials were performed during two days with fire safety engineering students at the F
