The objective of this paper is to give a new approach for identifying the human body parts like head, hands and legs for activity analysis. Here, the proposal is made for using different colour space algorithms for identifying the elements of the human body. We have used six dissimilar colour space algorithms such as RGB, YCbCr, HSV1, HSV2, HSI and rgb (Normalised RGB) to analyse the human activities in indoor video sequences. Here, 11 activities have been considered. In the proposed work, the RGB skin model provides the efficiency of 96.35% whereas YCbCr colour space algorithm gives 45.51%.
Sample preparation is the key to quality analysis with a laser analyser
Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than others. How well an analyser can tolerate dirty surfaces depends on many variables such as the nature of physical...
Application note issue #5 - Cement Analysis August 2017
Cement analysis using FP program (Fundamental Parameters) Cement is a blend of several minerals. It is critical to control the elemental composition and properties such as strength, setting, time and color. ED-XRF is being used to analyze the raw components, raw meal, clinker, and the final cement product (Na, Mg, Al, Si, S, K, Ca, and Fe in Cement, Clinker, and Raw Meal).XRF is at the heart of the control of the production process in any modern cement works and is central to the ability of the cement maker...

Quantitative Analysis of Geological Samples- X-Calibur
Abstract Quantitative and qualitative analysis of geological samples (rocks and river sediments) was performed on Xenemetrix EDXRF Benchtop Spectrometer System, model X-Calibur Objective: Perform XRF measurements on certified geological reference materials to build calibration curves for the major oxides (Na2O, MgO, SiO2, Al2O3, SiO2, P2O5, SO3, K2O, CaO, TiO2, MnO and Fe2O3) and for trace elements Cr, Co, Ni and Pb in these samples. Quantify geological samples of unknown concentrations with respect to...
