Measurements such as the person’s nose width‚ length of their forehead‚ and width of the lips are digitally stored and the data is used to identify a person; this process is known as geometrical recognition. An alternative process called photometric recognition‚ generates an outline of the facial features and uses the data for identifications. Data extracted from a picture can be scaled and be compared to other pictures in a database. The technology can be used to progress a child’s picture

Experiment 19 - Determination of the equilibrium constant for the reaction Fe3+ (aq) + SCN( (aq) = FeSCN2+ (aq) Object: To determine the equilibrium constant by a colorimetric method Theory: Colorimetric methods of analysis are usually applied to the determination of small concentrations of either inorganic or organic materials in a solution. The constituent sought must be coloured or must be capable of reacting with a reagent to produce a substance having a suitable colour. Beers Law‚ which

Work Specific Skills Work specific skills focusing on the use of standard operating procedures for different types of laboratory equipment‚ the calibration of standard laboratory equipment and the use of a lab book. This was chosen as a priority for me due to these skills being an essential part of any work I wish to do in the future‚ working or continuing my studies with in a lab. This set of skills is relevant to my skills matrix because it is a skill I have only had the chance to develop at

determine the accuracy of the copper and zinc composition percentages in a random sampling of pennies. The penny was dissolved to make aqueous copper ions and four copper dilutions were made from stock solution. Each cuvette sample was measured in a colorimeter and the data was plotted linearly using Beer’s law plot. Mass percent and percent error were found using calculations. Analysis of class data provided further data to determine the copper and zinc composition percentages. Experimental Procedure
