This paper proposes an efficient watermark generation method for audio copyright protection and digital right management. It proposes a method of generating pseudorandom sequences based on iris image templates. These biometric generated sequences (bio-keys) are found to be unique for distinct identification purposes. These bio-keys are used as the watermark for audio signals. The correlation of...

Unsupervised projection approaches can support Intrusion Detection Systems for computer network security. The involved technologies assist a network manager in detecting anomalies and potential threats by an intuitive display of the progression of network traffic. Projection methods operate as smart compression tools and map raw, high-dimensional traffic data into 2-D or 3-D spaces for subseque...

EIn order to reduce formaldehyde emissions, an experimental investigation of lightweight flax shives based particleboards, prepared using two different binders: bio-based lignin (lignosulfonate) and partially epoxy resin (greenpoxy 56), was undertaken. The particleboards (with a target density 500 kg/m³), were elaborated by thermo-compression process 20 wt% binder content. directly valorised as...

Title of dissertation: DYNAMICS AND AEROELASTICITY OF HOVER CAPABLE FLAPPING WINGS: EXPERIMENTS AND ANALYSIS Beerinder Singh, Doctor of Philosophy, 2006 Dissertation directed by: Professor Inderjit Chopra Department of Aerospace Engineering This dissertation addresses the aerodynamics of insect-based, bio-inspired, flapping wings in hover. An experimental apparatus, with a bio-inspired flapping...

The variation of moisture during sewage sludge bio-drying was investigated. In situ measurements were conducted to monitor the bulk moisture and water vapor, while the moisture content, water generation, water evaporation and aeration water input of the bio-drying bulk were calculated based on the water mass balance. The moisture in the sewage sludge bio-drying material decreased from 66% to 54...

Many feature subset selection algorithms have been proposed and discussed for years. However, the problem of finding the optimal feature subset from full data still remains to be a difficult problem. In this paper, we propose novel methods to find the relevant feature subset by using biologically-inspired algorithms such as Genetic Algorithm and Particle Swarm Optimization. We also propose a va...

Mobile robots have been used widely in large number of intelligent based applications, where a random manoeuvring is an essential part of such systems, [1,2]. In this regards, experience has shown that mobile robots do require advanced parallel intelligent based control mechanisms. In this article, it is shown how a mobile robot can be controlled in movement via some rule based system. In this ...

Abstract 5 The techno-economic potential of the UK poplar wood and imported oil palm empty fruit 6 bunch derived bio-oil integrated gasification and Fischer-Tropsch (BOIG-FT) systems for the 7 generation of transportation fuels and combined heat and power (CHP) was investigated. The 8 bio-oil was represented in terms of main chemical constituents, i.e. acetic acid, acetol and 9 guaiacol. The co...

Bio-energy, that is, energy produced from organic non-fossil material of biological origin, is promoted as a substitute for non-renewable (e.g., fossil) energy to reduce greenhouse gas (GHG) emissions and dependency on energy imports. At present, global bio-energy use amounts to approximately 50 EJ/yr, about 10% of humanity's primary energy supply. We here review recent literature on the amount...
