Eftersom information blir mer och mer tillgänglig börjar företag idag leta efter potentiella sätt att använda informationen för att blir mer attraktiva på marknaden. Ett sätt att utnyttja informationen på är att stödja datadrivna beslut. Målet med detta examensarbetet är att utveckla och designa en applikation som underlättar datadrivna beslut för företaget Grade AB. Detta genom att erbjuda behövaWith data becoming more and more abundant, companies will want to use this data in meaningful ways to gain competitive advantages on the market. One way of utilizing the data is to make data-driven decisions, which is often called data-driven decision-making. The goal of this master's thesis is to develop and design an application for the company Grade AB to alleviate data-driven decisions mad

The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. The optimisation possibili

The marine environment is a vital resource protecting our ecosystem and a critical part of the wellbeing of our planet. Marine Strategy Planning (MSP) is essential for conservation and protection of marine monitoring systems and governments should constantly improve their strategies and aim for increased effectiveness of these systems. This thesis focuses on marine conservation in Sweden and revie

About 20 percent of Sweden's municipal street network is now in urgent need of maintenance. This is assumed to correspond to a cost of about 12 billion Swedish crowns. That the streets are maintained in an effective manner is of great importance both for the users' safety and accessibility. Today, however, numerous municipalities suffer from a maintenance debt incurred because of the lack

Inter-frequency measurements are needed to determine when user equipment should make a handover to the best available base station in a cellular mobile network. The measurements are expensive from a resource point of view and therefore there is a need for optimization of this kind of measurements. In this work both this optimization and a way to predict the future of the measurements have been eva

The rise of Big Data is creating tremendous opportunities across all industries. As the development promises disruptive changes of business processes and manifold benefits both on the company and customer side, health and life insurance companies engage and invest in Big Data approaches. By collecting, storing, and analysing huge amounts of customer centric data, they hope to enhance their risk as

This project’s objective was to gather knowledge of ways to mechanically increase speech intelligibility and decrease wind noise through the design of microphone ports. The project focused on ports that would be applied in outdoor intercom products. The project used experimental testing through the development method Robust Design to investigate different parameters that could be changed in a

Finding vulnerabilities in open source software is an important part of software security. Software security is in turn a vital part in risk management and making risk assessments. The purpose of this thesis is to help organisations make decisions about vulnerabilities they have in their software programs by helping them make their own risk assessment. Our research uses the Common Vulnerability Sc

The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin. An alternative to these non-ren

På Lunds Tekniska Högskola studenter som studerar på programmet Civilingenjör inom Kemiteknik en obligatorisk kurs Energiteknik KETF30. Kursen har ett laborationsmoment om värmeväxling som behöver förnyas. Målet med kandidatarbetet är att få fram en laborationsbeskrivning med fokus på värmeväxlarens beteende beroende på olika parametrar och jämföra de två metoder som kan användas för att beskriva At Lund University, students in the program Chemical engineering have a compulsory course Heat Engineering (Energiteknik KETF30). The course has a laboratory practical concerning heat exchanger that needs to be renewed. The goal of this bachelor thesis was to write a description for the practical, focusing on the heat exchanger’s behavior considering different parameters and comparing the who comm

Sweden faces an upcoming period where thousands of buildings built during the million program period will be in need of a façade renovation. There is a large energy-saving potential in these buildings, since they are often poorly insulated and often have a ventilation system without heat recovery. Performing energy-efficient renovation measures to a building are expensive, which results in that th

The coastal city of Kalmar is known as an attractive summer destination, both locally and internationally. The coast has long been included as one of the municipality’s priority goals. In its city development vision, the municipality strives to utilize the coast and take it into consideration in urban planning. On the other hand, Kalmar has a historic character, which is visible through its urban

Radar is a technology that is widely used in many diverse areas; from monitoring space down to ocean surveillance, with many more applications in between. The technology existed before, but was mainly developed in secret by several nations during World War II. Radar technology uses radio waves to detect various kinds of objects and can determine their range, velocity and orientation. It is, theref

Den europeiska stålindustrin står för en betydande del av EUs CO2-utsläpp, men har samtidigt begränsade möjligheter att minska utsläppen från befintliga produktionsmetoder. Det krävs därför nya, banbrytande processinnovationer för att åstadkomma verkligt stora utsläppsminskningar. Denna rapport ger en översiktlig beskrivning av den europeiska stålindustrin teknologiska innovationssystem, belyst geThe EU steel industry is a major contributor to human-induced CO2 emissions and has limited possibilities to improve incumbent production methods further. The industry is therefore strongly dependent on new breakthrough decarbonisation technologies in order to further mitigate emissions. This report provides an overview of the EU steel industry’s technological innovation system, through a new mapp

The Internet of Things is coming. With it comes security challenges not present on common, more capable, devices such as desktop computers or servers. We argue that traditional channel security needs to be complemented with object security to cope with the constrained nature of small devices and Low Power Lossy Networks. The main reason for a partial transition to object security being heavy use o

The automotive industry is a field of enormous competition. Customers and regulations demand economical and sustainable products. To achieve maximum efficiency, engine systems require detailed control. To increase the accuracy of the models that describe the combustion process, a demand has arisen at Scania for an exact prediction of the combustion chamber volume. During engine operation, the com

Linearity and high efficiency are crucial requirements for any power amplifier. However, power amplifiers have high efficiency levels when they are in non-linear regions. To overcome this issue there have been many suggestions in literature, one of the most successful methods is digital predistortion method. Digital predistortion (DPD) method’s low resource usage and fairly easy algorithm dr
