The Modelica language is an object-oriented, equation-based language used for modeling and design in many different domains and for various physical applications. In order to exchange models both between Modelicabased tools and other tools the Functional Mock-up Interface (FMI) has emerged. This interface enables exchange of virtual models between manufacturers and/or divisions within a company. T
El Niño and the Southern Oscillation (ENSO) have a great impact on global climate, often with disas-trous effects in many parts of the world. The carbonate skeleton of corals record El Niño activity by tracing sea surface temperature and salinity in the oceans where they grow. As El Niño’s core region is the equatorial Pacific Ocean, this is where the most direct consequences of ENSO are seen, com
One of the topics that has generated discussions and focuses on demographic theory is undoubtedly the treatment of fertility rates, another important number of studies have incorporated different methods for measuring behaviors in count data, such as Poisson models, also used in the present document. On the other hand, by using panel data, we estimate a random effects model and evaluate the dete
Solar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. However, the atmosphere is constantly changing, which makes for
The accuracy and portability of depth cameras have increased by a lot in recent years, which allows for advanced 3D scanning of the environment for robotic applications. In this thesis we have developed a system that uses a depth camera mounted on a robot arm to identify and localize arbitrary objects, and give hints on how to move the camera to get better localization results. The system works by
This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. The first class of algorithms relates to the calibration of the transceiver (TRX) chains responses of the antenna array and makes use of the antenna array mutual coupling, which
South East Asia, and Thailand in particular, are experiencing rapid population ageing. In Thailand older people are increasing in both proportion of the population and absolute number. Adaptations are needed to support this ageing population and to prevent poverty in old age. Since 2009 Thailand has had a minimum universal social pension, the Old Age Allowance (OAA) for all citizens aged 60 and ov
Although nanoparticles (NPs) are very small, their field in science is currently growing very large. There are several biological, medical and technical applications possible for NPs when bound to proteins. Protein-NP interactions are difficult to predict and therefore a lot of fundamental research is yet to be completed. This study is an attempt to contribute with the aim to explore the interacti
Several governments recently adopted strategies to facilitate the development of artificial intelligence (AI), one of the reasons being the pursuit of sustainability – a claim with little scientific grounding so far. In this thesis, I strived to outline the scope of AI’s potentials by showing i) the limits of its theoretical and practical usefulness and ii) the political barriers to using it for s
The development of sports within the European Union (EU) has been blooming the latest century, especially in the football sector, which has been transformed into a multi-billion industry. The development of European football has attracted investors outside the EU into heavy investing in football clubs across Europe. This has enabled purchases of new talents and high profile players for astronomica
The aim is to develop a profound comprehension of what role knowledge plays in the process of integrating the internal knowledge within organizations with the external knowledge that can be found in the surrounding cluster initiatives. This research contains a qualitative case study which was developed by following an interpretative, abductive approach that granted the authors to work with theory
Increase of urbanization and climate change are one of the factors that have been highlighted to influence the change of urban runoff hydrograph. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding is the main problem that arises. To solve this, the sustainable urban drainage system techniques are adopted for reducing peak flow and increase baseflow. This t

The goal of this Master's Thesis is to successfully detect and classify humans in a LiDAR data stream. The focus of the Thesis is on the detection and classification, not on the LiDAR technology. To classify humans machine learning was used and to train the machine learning model we collected our own data and annotated it. A custom software was made for speeding up the annotation process.
Abstract Title: Developing an Inventory Control Policy and Forecasting Model for an E- Commerce Company Authors: Patrik Lorentsson & Nilan Nabavieh Supervisor: Johan Marklund, Department of Industrial Management and Logistics Background: Increasingly competitive business environments forces companies to develop better control of the material flows in their supply chain. Inventories are oft
Background: In workplace health promotion, all potential resources needs to be taken into consideration, not only factors relating to the absence of injury and the physical health of the workers, but also psychological aspects. A dynamic balance between the resources of the individual employees and the demands of work is an important prerequisite. In the home care services, there is a noticeable t
An experimental study of nuclear reactions between Si-28 nuclei at 200 and 300 MeV/nucleon and hydrogen or deuterium target nuclei was performed at the CELSIUS storage ring in Uppsala, Sweden, to collect information about the reactions responsible for single-event effects in microelectronics. Inclusive data on Si-28 fragmentation, as well as data on correlations between recoils and spectator proto
Background: Although widely used, the validity and reliability of the Clavien classification of postoperative complications have not been tested in urologic procedures, such as percutaneous nephrolithotomy (PCNL). Objective: To validate the Clavien score and categorise complications of PCNL. Design, setting, and participants: Data for 528 patients with complications after PCNL were used to create
There is currently a strongly growing interest in obtaining optimal control solutions for vehicle maneuvers, both in order to understand optimal vehicle behavior and to devise improved safety systems, either by direct deployment of the solutions or by including mimicked driving techniques of professional drivers. However, it is nontrivial to find the right mix of models, formulations, and optimiza
