Explanation: master grade is laboratory standard and made from steel carbide or tungsten carbide. tool grade is normal industrial purpose angle gauges made from steel.
Explanation: versatility of angle gauges increases when used with a square plate. square plates with angle gauge can measure angle greater than 90o.
Explanation: standard a has 13 gauges and standard b has all gauges from standard a except 0.05’ i.e. 12 gauges.
Explanation: these are low-power instruments. laser systems have wide dynamic range, high contrast and low optical cross-talk. laser systems can be used in inspection of surfaces and in dimensional measurements and are very useful in precision and accuracy measurements.
Explanation: he-ne lasers are used in laser inspection. light produced by he-ne lasers is at a wavelength of 6328 Å or 0.6 μm and that is in phase and coherent. this source is a 1000 times more intense than other monochromatic sources.
Explanation: we can define topology as the study of properties of a figure that are unaffected by any deformation, as long as there is no joining or tearing of the figure. we use topological properties in the region description.
Explanation: if a topological descriptor is defined by the number of holes in an image, then the number of holes will not vary if the
Explanation: we know that, as stretching affects distance, topological properties do not depend on the notion of distance or any properties implicitly based on the concept of distance measures.
Explanation: the image shown in the question has two holes and one connected components. so, the euler number e is given as 1-2=-1.
Explanation: it is very important to classify the polygonal network. let v,q and f denote
