This report covers the implementation and evaluation of a Breadth-First Search operand for the Neo4j graph database and the Cypher query language. The evaluation compared the pre-existing Depth-First Search operand with both a non-optimized and two different optimized Breadth-First Searches. The focus of this evaluation was the runtime and memory usage for the different operands and to find out fo
This master’s thesis investigates the possibility to integrate an existing vehicle model from Simulink into the main testing software, CANoe. The purpose of integrating this was to achieve autonomous testing of real driving scenarios in an electronic control unit. This would in turn simplify and thus improve the test environment and test procedure at BorgWarner. By utilizing a vehicle model simila
Syftet med detta arbete var att designa och bygga en externt driven proteshand. Handen ska helst ha en eller flera funktioner som inte finns hos andra protester. Den mänskliga handen är väldigt komplex, den innehåller över 30 muskler och minst 18 leder. Jämförelsevis har en komplex och rörlig kommersiell protes fem aktuatorer och elva leder, men endast en eller två kontrollsignaler. Allt som allt The purpose of the thesis was to design and build an externally powered prosthetic hand. The hand should preferably have one or more new functionalities not found in other prostheses. The human hand is very complex, it contains over 30 muscles and at least 18 joints. In comparison, a complex and dexterous commercial prostheses has five actuators and eleven joints, but only one or two control signa
This BSc thesis focuses on trying to find approximate solutions to partial differential equations using the Fourier collocation method. This method uses Fourier basis functions to approximate the solution to a partial differential equation with periodic boundary conditions. Using Fourier basis functions, one does not need to use large matrices, which makes all computations relatively fast. Another
Spray painting by hand is a strenuous task for the operator and his shoulder joints. Today this is how the procedure is done at the Metso Sweden AB factory in Trelleborg. This thesis will analyze the spray painting process and investigate and implement a semi-automated robot which can be remote controlled from a safe environment as well as automated. The implementation has a focus on using vision
This report considers the problems of using a model-based approach to develop an estimation for a non-linear system using a linear model. Different estimation approaches were researched and evaluated using an ideal system, thus finding the suitable method for this thesis. The investigations considered both drive-train friction and the identification of oscillatory modes in a real industrial robot
Object classification has made great progress lately and a lot of it has to do with the advances in machine learning, processing power, and deep convolution neural networks. Today a camera can detect and classify objects with high precision using trained neural networks, but there is still room for improvements. Cameras using different spectrum, like visual and thermal, have their strengths and we
Artificiell intelligens (AI) används idag inom en rad olika områden som sjukvård, ekonomi, marknadsföring, bildanalys och taligenkänning. Syftet med den här undersökningen är att se vilken plats AI har, och kommer att få, inom arkitektur och stadsplanering. Genom en litteraturstudie samt intervjuer av representanter från några svenska arkitektkontor undersöker jag vilken effekt AI kan få på hur vi
Malmö is growing. By 2030 the north harbor will house a new neighborhood with the goal of bringing 3000 residents closer to the city center. Building vertically, roof top kindergartens and a large number of courtyards are some of the visions of the concept suggested by the architects. This new neighborhood and situation requires furniture accordingly and public furniture producer Nola wants to dev
Osteoporosis is a bone disease that is defined as low bone mineral density (BMD) and results in an increased risk of bone fracture. It is a serious public health problem that causes excess mortality and major economical and social impact. Today there are more than 8.9 million fractures connected to low bone mineral density worldwide. Hip fractures are of particular concern since they are associate
I en värld där samhället ställer höga krav på produkter, både sett till design och funktionalitet är behovet av vidareutveckling av befintliga produkter högt efterfrågat. Vissa produkter har dock halkat efter i denna utveckling och en av dessa som har identifierats är picknick-korgen som under de senaste åren inte har utvecklats till mer än vad den alltid varit, nämligen en väska med kylfunktion f
An Extreme Value Approach To Pricing Credit Risk will outline the possibility to investigate a company’s price of risk over different time periods given a pre-defined risk level. With help of credit default swap (CDS) prices and extreme value theory the credit risk can be estimated for different return levels. This is incorporated by investigating monthly CDS data from Deutsche Bank AG EUR CDS 5Y
Sammanfattning: I Sverige finns idag certifierade och icke-certifierade astma/KOL-mottagningar inom primärvården. Forskning visar att inhalationsteknik inte förbättrats de senaste 40 åren. Syfte: Syftet med studien är att undersöka om det finns skillnad i patienters uppfattningar om sin kunskap och den information de fått om inhalationsteknik vid en certifierad astma/KOL- mottagning och en icke ce
Poland with its long coal and landfilling traditions struggles to reach the European Union goals for both the share of energy produced from renewable sources and management of biodegradable waste. Biogas is proven to be a part of a sustainable solution addressing the problem of organic waste utilisation while providing an opportunity for renewable energy generation as well as for nutrients recycli
One of the modern cities environment issues is noise and vibration created by train traffic, especially since cities today strive towards being more dense. Urbanization leads to new areas built with pre existing railway tracks. This puts a lot of pressure on the structures built on those areas regarding vibrations. Heavy concrete buildings are more resilient against vibrations than light-weight st
Iceland is known for its remote location and rough beauty. In their seclusion, the Icelanders have built an independent and peaceful country. They are undeniably a very unique nation, where police officers are not allowed to carry guns, except on special occasions. The society displays a relaxed attitude towards prisons, which are built without concrete walls around. However, faced with the immens
The idea to artificially enhance our physical abilities has always fascinated humankind and over the cause of history it has resulted in countless important innovations such as wheelchairs and carbon-fiber-reinforced polymer leg prosthetics. By combining electronics and Artificial Intelligence the step towards artificially enhanced limbs has been greatly reduced. This master’s thesis describes the
Real-time bidding is getting increasingly popular for buying and selling online display advertisement. This has spurred a research interest into how to design optimal bidding algorithms, with advances during the last two to three years focusing heavily on reinforcement learning. This thesis focuses on creating bidding agent using recent innovations in combining reinforcement learning and deep lear
Dyslexia is a problem that can limit someone’s life if the person does not receive the appropriate support in order to develop strategies to deal with it, and it is not limited to one’s first language. The first limitations appear early in life during the school years as the child struggles with literacy issues. It is in the educational environment where the child will receive the first support a
