This paper presents a novel method to correlate audio and visual data generated by the same physical phenomenon, based on sparse geometric representation of video sequences. The video signal is modeled as a sum of geometric primitives evolving through time ...
This work outlines two approaches for small unmanned aerial vehicles (UAVs) performing surveillance with fixed cameras. Small UAVs present significant control challenges, due to relatively low-bandwidth actuation and significant disturbances due to wind. T ...
TASC (TYRES/TRACKS AND SOIL COMPACTION) is an Excel tool designed foremost as an aid in arable farming. The vulnerability of the soil to the passage of wheels or tracks is assessed after considering soil and load property factors. Danger of soil compaction ...
Spent railway ballast is a source of recycled aggregate. Recycling of aggregates contributes to sustainable development by reducing the volume of construction waste going to landfill, reducing transportation and reducing the impact of primary mineral extra ...
Railway ballast provides both the foundation and drainage for railway track. It can become heavily contaminated with diesel fuel due to leakage and spillage. Typical analytical methods for soils may not be applicable to the assessment of ballast. The effic ...

We present an algorithm for tracking video object which is based on an hybrid strategy. This strategy uses both object and region information to solve the correspondence problem. Low level descriptors are exploited to track objects regions and to cope wit ...
There is increasing concern about environmental pollution by diffuse emissions of various environmental hazards emitted by transportation activities. For the first time substances released by railways to the environment were investigated. We considered the ...
So-called “non-load bearing” parts of (railway) bridges increase the stiffness and decrease the stresses in short span bridge structures. The rail track, consisting of ballast, sleepers and rails, has a non-linear behaviour and its rigidity depends on the ...
