    Abstract : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

  3. 2. Analysis of machine learning for human motion pattern  recognition on embedded devices

    University essay from KTH/Mekatronik

    Author : Tomas Fredriksson; Rickard Svensson; [2018]
    Keywords : ai; machine learning; embedded systems; internet of things; human motion analysis; support vector machines; decision tree; random forest; features; cortex m-series; ai; maskininlärning; inbyggda system; internet of things; människliga rörelser; support vector machines; decision tree; random forest; features; cortex m-series;

    Abstract : With an increased amount of connected devices and the recent surge of artificial intelligence, the two technologies need more attention to fully bloom as a useful tool for creating new and exciting products. As machine learning traditionally is implemented on computers and online servers this thesis explores the possibility to extend machine learning to an embedded environment. READ MORE

  4. 3. Methodology for analysis of traffic-induced building vibrations

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Rickard Torndahl; Tobias Svensson; [2017]
    Keywords : infinite elements; soil dynamics; structural dynamics; wave propagation; dynamic reduction; traffic-induced vibration; finite element method; building vibration; structural design; Technology and Engineering;

    Abstract : Urban population growth leads to denser cities where buildings are being constructed closer to sources of vibration like motorways, railways and tramways. The risk of disturbing vibrations is thereby increasing which could affect residents and sensitive equipment, for instance equipment used in hospitals. READ MORE

  5. 4. Exoskeleton arm : How to construct a smart support structure for an arm

    University essay from KTH/Mekatronik

    Author : CHRISTOFFER BATOR; RICKARD SVENSSON; [2016]
    Keywords : ;

    Abstract : The purpose of this thesis was to find an optimal way to construct and control a product that could help those who suffer from muscle weakness or a muscle sickness. The device was made out of two major parts (upper arm and lower arm) which were connected through a motorized joint. READ MORE

  6. 5. Cued Click-Point Memorability

    University essay from Linnéuniversitetet/Institutionen för datavetenskap (DV)

    Author : Rickard Svensson; [2015]
    Keywords : User Authentication; Graphical Passwords; Cued Click-Points;

    Abstract : The Safety of passwords has been in question for over 40 years, long before the Internet. While improvements have been made to ensure security nothing has changed with passwords since the emergence of the Internet. Passwords need to be long and complex to be secure and users should not reuse their passwords. READ MORE
