The Peak Particle Velocities (PPVs) were measured at several station points in the vicinity of a limestone quarry in Turkey, and a Scaled Distance (SD) value for each individual blast was calculated. A linear regression analysis was performed and results were plotted. An attenuation equation unique ...

In spite of simplicity and effectiveness in segmenting homogeneous regions in an image, Split-and-Merge (SM) algorithm is unable to segment all types of objects due to huge number of objects with myriad variations among them and due to high dependability on the threshold values used in splitting and ...

Tin Oxide (SnO2) thin films grown on glass substrate at 648 K using direct evaporation method with two gold pads deposited on the top for electrical contacts were exposed to ethanol vapours (200-1000 ppm). The operating temperature of the sensor was optimised. The sensitivity variation of films having ...

In most of the real life applications of imaging, the Point Spread Functions (PSFs) responsible for degrading the observed images are not known. Hence, PSF and image must be identified from the observed noisy blurred image. Here, we present a computationally simple iterative blind deconvolution algorithm ...

This paper discusses ongoing research regarding the application of theoretical probability distributions to a reliability assessment model called GenRel. GenRel is a computer model for reliability analysis of mining equipment based on Genetic Algorithms (GAs). The reliability changes over time due to ...

The purpose of this paper is to present a theoretical analysis of B-spline signal representation from a signal processing point of view. The noise component included in the measured signal waveform greatly affects the result of numerical signal waveform processing. In order to suppress the harmful influence ...

Indium Tin Oxide (ITO) thin films have been grown on glass substrates using a direct evaporation method. After deposition, two gold pads were added on the top to make electrical contact to the sensing film. The operating temperature of the sensor was optimised at 673 K and exposed to acetone vapour ...

This paper presents two new ideas to improve the performance of Radial Basis Function (RBF) networks. In the first instance, we choose a set of patterns for training, which are closer to decision boundaries, from different classes of training samples that constitute the input space. We call those set ...

Changes in cleat permeability of coal seams are influenced by internal stress, and release or adsorption of gas in the coal matrix during production/injection processes. Coal shrinkage swelling models have been proposed to quantify such changes; however none of the existing models incorporates the effect ...

The DSP system was customised to control the data acquisition process of 16 × 16 optical sensors array, arranged in parallel beam projection. The data collected was used to reconstruct the cross sectional image of the pipeline conveyor. For image display purpose, the reconstructed image was sent to ...
