1. Adaptive tensor-based morphological filtering and analysis of 3D profile data
Sammanfattning : Image analysis methods for processing 3D profile data have been investigated and developed. These methods include; Image reconstruction by prioritized incremental normalized convolution, morphology-based crack detection for steel slabs, and adaptive morphology based on the local structure tensor.

2. Spatial decomposition of ultrasonic echoes
Sammanfattning : The pulse-echo method is one of the most important in ultrasonic imaging. In many areas, including medical applications and nondestructive evaluation, it constitutes one of the fundamental principles for aquiring information about the examined object. LÄS MER
3. Multiple-Input Multiple-Output Radio Propagation Channels : Characteristics and Models
Sammanfattning : In recent years, deploying multiple antennas at both transmitter and receiver has appeared as a very promising technology. By exploiting the spatial domain, multiple-input multiple-output (MIMO) systems can support extremely high data rates as long as the environments can provide sufficiently rich scattering. LÄS MER
4. Methods to Improve the Selectivity of Gas Sensor Systems
Sammanfattning : In several situations it is essential to be able to measure the composition of a gas mixture, discriminate between or quantify different gases mixtures (odors), or in some cases to give a 'fingerprint', which represents the gas mixture. A gas sensor system is designed to measure certain attributes of a gas mixture. LÄS MER
5. Characteristics of Vertical Forest Backscatter Profiles Measured using Radar Tomography
Sammanfattning : Forests are an integral part of the Earth’s climate system, having shaped the conditions of life throughout millions of years, but the coverage and conditions of forests are under rapid change. To monitor this change and predict the impact on climate, yearly global mapping of forest Above-Ground Biomass (AGB) is needed. LÄS MER
