We show that nanoimprint lithography combined with electron-beam evaporation provides a cost-efficient, rapid, and reproducible method to fabricate conical nanostructures with very sharp tips on flat surfaces in high ...

A novel nonparametric concavity point analysis-based method for splitting clumps of convex objects in binary images is presented. The method is based on finding concavity point-pairs by using a variable-size rectangular ...

OpenCL is a programming language standard which enables the programmer to express the application by structuring its computation as kernels. The OpenCL compiler is given the explicit freedom to parallelize the execution ...

We prepare diffractive planar arrays of metal nanoparticles that are chiral because of either the shape of individual particles (“molecular” chirality) or the orientation of achiral particles in the array (“structural” ...

The aim of this paper is to evaluate the impact of selected topology planning aspects on performance of WCDMA cellular network and mobile positioning techniques. The assessment is based on field measurements and simulations. ...

We present a novel ordinal co-occurrence matrix framework for the purpose of content-based texture retrieval. Several particularizations of the framework will be derived and tested for retrieval purposes. Features obtained ...

Color is the major source of information widely used in image analysis and content-based retrieval. Extracting dominant colors that are prominent in a visual scenery is of utmost importance since the human visual system ...

A photoacoustic (PA) sensor has been developed for the detection of nitrogen dioxide (NO2). Ten amplitude-modulated high-power light emitting diodes (LEDs), emitting a total optical power of 9W at 453 nm, are used to excite ...
