Machine learning in general, and artificial neural networks in particular, have gained a lot of attention in recent years. Using deep neural networks for classification tasks, such as face recognition, has proven more and more successful over time. The performance increase is partly due to more complex network architectures, and partly due to the use of larger datasets. The increased complexity of
The lack of availability and relevance of both credit ratings and traded market instruments, forces nancial institutions to nd alternative ways to validate the credit qualities of their counterparties. To address this issue, existing bankruptcy prediction models are evaluated and re-estimated. Furthermore a new model is constructed that outperforms the previous models in terms of default classicat
To simulate district heating networks, in this project the simulation environment Dymola was used. The goal was to run simulation of district heating network and at the same time have good network representation to easily change between different models and also change between doing simulation and optimization. Different models had to be created in Dymola and tested to ensure they work accordingly
In recent years the capital requirements for banks have been updated which has complicated the pricing procedure for derivatives. Nordea has developed a proxy model that approximates the risk measure Exposure At Default, which is an important component in the recently updated requirements. The purpose of this thesis is to validate the accuracy of Nordea’s model. In order to fulfill this purpose, m
Conclusions: The findings of this paper suggest that there is a need for banks to adjust their management control systems (MCS) if they are to foster innovations and be truly ambidextrous. The design of the MCS seems to be of significant importance to achieve contextual ambidexterity. This is concluded as we have found tensions between innovative activities and the banks’ MCS, which are designed f
Extrema regn förväntas ske både oftare och slå med större kraft i framtiden enligt prognoser från FNs klimatpanel. Vid extrema regn, eller skyfall, är det praktiskt taget omöjligt att undvika översvämningar i ledningssystemen, då ledningarna inte är dimensionerade för att klara så stora flöden som dessa regn medför. För att minimera skadorna vid översvämningar spenderar svenska myndigheter enorma Forecasts on the climate change are pointing towards an increased amount of extreme rains or cloudbursts in the future. Cloudbursts are already today a big problem. When cloudbursts occur over dense urban areas, flooding occurs. To prevent damage to property and important functions for society, Swedish municipalities spend an enormous amount of money every year. To make sure that the investments a
This thesis describes the process to build an entity recognizer and disambiguator, named HERD. The goal of the system is to find mentions of entities in text and link those mentions to a unique identifier. This system is designed to be multilingual and has versions in English, French and Swedish. I use Wikipedia as a knowledge source of both names and concepts, and Wikidata, a language agnostic,
This master thesis project reports the dependence on pH of the conformational exchange in the enzyme FKBP12. Previous NMR studies have identified two conformational exchange processes in FKBP12, where the faster process is believed to be an exchange to an intermediate state between the more slowly exchanging conformations. In this project I carried out different NMR experiments across the pH-inte
Today’s rapidly changing environment amplifies the need for companies no matter the industry, to stay on top of their game and not lose market share to competing firms. This is particularly true of companies in mature industries, and therefore, is a worthy area of study and the focus of this thesis. Rethinking Competitive Strategy in Mature Industries is an in-depth, exploratory study, with an em
Software development for embedded systems has a lot of dependencies on the hardware of the system. To possibly reduce the lead time and ease the development process, an emulated model is investigated. This model is examined in terms of how it fits in the platform transition, daily development and testing processes at Axis. The results indicate that an emulated model is a powerful tool for a softwa
Spatial relationships are a comprehensive and essential part of geographical information management and GIS. Topological relationships are a subgroup of the spatial relationships. They are defined by the fact that they do not break under topological transformations, meaning they remain when stretching, twisting or crumbling the underlying space. Topological relationships are for instance relations
Abstract Responsive web design is the technique lot of companies apply to their website today. The reason is, that with this technique the website’s content adapts nicely on all devices from mobile phones to desktops. IKEA recently followed this trend on some of their platforms and among these is their internal communication platform called IKEA Inside Outside. IKEA is not entirely satisfied in
Användningen av smarta telefoner och områden i vilka smarta telefonlösningar erbjuds, har ökat drastiskt det senaste decenniet. Det område som däremot inte har varit lika benäget att anta detta tillvägagångssätt är restaurangbranschen. Målet med denna studie syftar till att undersöka hur villiga användare är att anpassa sig till detta tillvägagångssätt och beskriver de krav och önskemål av en sådaThe use of smart phones and the areas in which smart phone solutions are provided have increased immensely over the past decade. However, one area which has not been as keen of adopting the smart phone approach is the restaurant area. This study aims to investigate the amenability of users to adapt to this approach and outlines the requirements and desires of such a product. It also presents a sol
In this thesis, two methods were developed for a web-based GIS to make the spatial perspective of flood disaster risk reduction and response accessible. Flood disaster can cause major disruption to the street network, which further affects the emergency services and evacuation work in finding the safest and fastest routes. Thus, a method for dynamic street network analysis was developed and implem
The present thesis explores the elements that affect the relationship between importers and exporters of agricultural products, using as case study the market for tropical fruits in Sweden. For this, the thesis looks into secondary data, backed with some interviews, to i) identify some of the perceptions and expectations that importers of tropical fruit have, ii) the way these affect the possibili
The purpose of this thesis was to reduce the start-up and restart time of a hemodialysis machine by targeting time consuming control loops. This was done by investigating different techniques of modelling to find the best combination of versatility and conformity to the process. Finding the best controller was done by evaluating different controllers in simulations with the model in MATLAB/Simulin
The aim of this study was to examine attitudes surrounding the needle exchange program in Malmö and Lund in Sweden. More specifically the aim was to examine how the staff of the needle exchange program experience the attitudes surrounding the needle exchange program and if/how these attitudes affect them in their work. The analysis of nine interviews with staff members revealed similarities in how
In June the 23, 2016 United Kingdom will hold a referendum on their EU-membership. One of the triggers was the letter that David Cameron sent to Donald Tusk November 10, 2015: “A settlement for the United Kingdom in a reformed Union“. The purpose of the present thesis is to make a profound analysis of David Cameron’s letter, analyzing the proposals and demands he places on EU. Cameron has four ma
This report is made in order to evaluate the fire safety for the personnel and patients at Ystad hospital. A risk analysis was conducted, focusing on hazards related to fire, and on the client's wishes it was determined that the analysis should be done on the section of the hospital called building 17 and that the writers especially should consider the risk of arson. Through the analysis two d
