  1. 16. Visual Quality Improvement of Digital Video by Stabilization Using Adaptive CMAC Filtering

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Amir Zahoor; Wittaya Koodtalang; [2013]
    Keywords : Digital video stabilization; DVS; Cerebellar model articulation controller; CMAC; Smoothness index; Peak signal to noise ratio; Point spread function;

    Abstract : A Digital Video Stabilization (DVS) system removes the unwanted shaking in the videos acquired by hand-held cameras and preserves the panning. In this thesis work, a digital video stabilization model is proposed based upon adaptive cerebellar model articulation controller (CMAC) filtering. READ MORE

  3. 17. Dynamic Modeling and Simulation of Digital Displacement Machine

    University essay from Fluida och mekatroniska system; Tekniska högskolan

    Author : Sanjib Chakraborty; [2012]
    Keywords : Digital Displacement machine; Digital Hydraulics; Hopsan; Digital fluid power; Generic model;

    Abstract : Improved efficiency, better controllability and low noise are the most demanding features form a displacement machine now-a-days. Most of the conventional displacement machines are basically a reciprocating pumping element controlled by valve plates or with the help of check valve [1]. READ MORE

  4. 18. Attenuation of Harmonic Distortion in Loudspeakers Using Non-linear Control

    University essay from Reglerteknik; Tekniska högskolan

    Author : Marcus Arvidsson; Daniel Karlsson; [2012]
    Keywords : EKF; exact linearisation; feed-forward; loudspeaker modelling; non-linear control; UKF;

    Abstract : The first loudspeaker was invented almost 150 years ago and even though much has changed regarding the manufacturing, the main idea is still the same. To produce clean sound, modern loudspeaker consist of expensive materials that often need advanced manufacturing equipment. READ MORE

  5. 19. Building a simple spectrum analyzer with dsPIC30F4013  

    University essay from Akademin för teknik och miljö

    Author : Xiangyu 翔宇 Lian 连; Chunguang 春光 Jiang 姜; [2011]
    Keywords : FFT; spectrum analyzer; dsPIC30F;

    Abstract : FFT-based digital spectral analyzer has become more and more widely used as a result of the development of Digital Signal Processing (DSP) techniques. Modern Analog-to-Digital Converters (ADC) and processors have made it possible to make fast measurements with a limited number of hardware. READ MORE

  6. 20. Simulation of the BMR450 DC/DC converter

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sriharsha Santhapur; Shivachaitanya Mamdur; [2011]
    Keywords : DC DC converter; BMR 450; Buck converter; MATLAB Simulink; PID Controller; state space analysis; Network Analysis; SimPowersystems;

    Abstract : This thesis is a part of collaborated project between Ericsson AB and Blekinge Institute of Technology to develop signal processing methods to be used in digital power in order to increase the functionality, performance and reliability of dc-dc converters. The task of this project work is to model a buck converter and a measurement system to sense the inductor current and output voltages of the buck converter system of Ericsson’s BMR450. READ MORE
