  1. 21. Uncertainty Quantification of a Large 1-D Dynamic Aircraft System Simulation Model

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Johan Karlén; [2015]
    Keywords : Uncertainty; Quantification; Dynamic; Modelica; Dymola;

    Abstract : A 1-D dynamic simulation model of a new cooling system for the upcoming Gripen E aircraft has been developed in the Modelica-based tool Dymola in order to examine the cooling performance. These types of low-dimensioned simulation models, which generally are described by ordinary differential equations or differential-algebraic equations, are often used to describe entire fluid systems.

  3. 22. Pedestrian Detection Using Convolutional Neural Networks

    University essay from Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakulteten

    Author : David Molin; [2015]
    Keywords : Convolutional neural network; pedestrian detection; Caltech pedestrian dataset;

    Abstract : Pedestrian detection is an important field with applications in active safety systems for cars as well as autonomous driving. Since autonomous driving and active safety are becoming technically feasible now the interest for these applications has dramatically increased. READ MORE

  4. 23. The Performance of Dual-Hop Decode-and-Forward Underlay Cognitive Relay Networks with Interference Power Constraints over Weibull Fading Channels

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Andawattage Chaminda Janaka Samarasekera; [2014]
    Keywords : Cognitive Radio; Weibull Fading Channels; Cooperative Communication; Cognitive Relay Networks;

    Abstract : With the rapid development and the increasing use of wireless devices, spectrum scarcity has become a problem. The higher frequencies have bad propagation characteristics and the lower frequencies have low data rates, therefore the radio spectrum that is available for efficient wireless transmission is a limited resource.

  5. 24. Performance Analysis of 3-hop using DAF and DF over 2-hop Relaying Protocols

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Faisal Mehmood; Muneeb Ejaz; [2013]
    Keywords : Bit Error Rate; Cognitive Radio; Decode Amplify and Forward; Energy Detection; Probability of Detection; Rayleigh Fading; Relay Network;

    Abstract : In wireless Communication, the need of radio spectrum increases nowadays. But in the system we are losing approximately 82-86% of spectrum most of the time due to the absence of Primary User (PU). To overcome this issue Cognitive Radio (CR) is an admirable approach. READ MORE

  6. 25. EEG enhancement for EEG source localization in brain-machine speller

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Parinaz Babaeeghazvini; [2013]
    Keywords : Brain-Computer interface BCI ; Brain-machine speller; Electroencephalogram EEG ; source localization; source reconstruction;

    Abstract : A Brain-Computer Interface (BCI) is a system to communicate with external world through the brain activity. The brain activity is measured by Electro-Encephalography (EEG) and then processed by a BCI system. EEG source reconstruction could be a way to improve the accuracy of EEG classification in EEGbased brain–computer interface (BCI). READ MORE
