1. 1. Removal of ultrafine particles by intermediate air filters in ventilation systems. Evaluation of performance and analysis of applications

   Författare :Bingbing Shi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurements; ultrafine particles; lifetime cost; indoor air quality; health effect; air cleaning; particle source; modelling; intermediate filter; filter standard;

   Sammanfattning : Epidemiological and toxicological studies demonstrate that ultrafine particles (UFPs) are strongly related with respiratory and cardiovascular diseases and syndromes. One common method to reduce human exposure to particulate air pollution is the use of intermediate class filters (F5-F9 class filters according to EN779:2002). LÄS MER

3. 2. Fast multi-dimensional filter networks : design, optimization and implementation

   Författare :Björn Svensson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : As the title implies a fast filter network is a structure of filters, designed for efficient computation of a set of multi-dimensional filters. The efficiency is due to decomposition of multi-dimensional filter sets into a structure of smaller sparse filters called sub-filters. LÄS MER

4. 3. On computational methods for nonlinear estimation

   Författare :Thomas Schön; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; Particle filter; Kalman filter; System identification; Convex optimization; Differential-algebraic equation; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The Bayesian approach provides a rather powerful framework for handling nonlinear, as well as linear, estimation problems. We can in fact pose a general solution to the nonlinear estimation problem. However, in the general case there does not exist any closed-form solution and we are forced to use approximate techniques.

5. 4. Techniques for Efficient Implementation of FIR and Particle Filtering

   Författare :Syed Asad Alam; Oscar Gustafsson; Kent Palmkvist; Yajun Yu; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filter; Particle filter; architecture; ASIC; FPGA;

   Sammanfattning : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters. LÄS MER

7. 5. Sensor Fusion for Automotive Applications

   Författare :Christian Lundquist; Fredrik Gustafsson; Thomas B. Schön; Uwe Hanebeck; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kalman filter; PHD filter; extended targets; tracking; sensor fusion; road model; single track model; bicycle model;

   Sammanfattning : Mapping stationary objects and tracking moving targets are essential for many autonomous functions in vehicles. In order to compute the map and track estimates, sensor measurements from radar, laser and camera are used together with the standard proprioceptive sensors present in a car. LÄS MER
