NIGHT VISION TECHNOLOGY ABSTRACT A night vision device (NVD) is an optical installment that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies‚ but are available to civilian users. The term usually refers to a complete unit‚ including an image intensifier tube‚ a protective and generally water-resistant housing‚ and some type of mounting system. Many NVDs also include sacrificial lenses‚ IR illuminators

Semiconductor The diode – A diode is an electronic component which allows electric current to glow in only one direction. Diodes are constructed from semiconductors. The anode is the positive terminal and the cathode the negative terminal. LED= light emitting diode a diode which emits light. Semiconductor materials Silicon is the most commonly used semiconductor in electronics‚ germanium is also used. These elements form a stable crystal lattice‚ with each atom sharing its four outer electrons

6. TREATMENT METHODS Screening‚ grit removal‚ flow equalization‚ sedimentation‚ or dissolved air flotation are used to reduce suspended solids (SS) load from sugar industry wastewater. Biological treatment includes aerobic and anaerobic process. Except biological methods‚ physico-chemical methods are also used for sugar industry wastewater treatment. 6.1 Biological methods Since‚ sugar industry wastewater contains mostly sugars and volatile fatty acids‚ which are easily biodegradable‚ therefore all

1. Results Part 1: When samples of austenitic stainless steel are immersed in a sulphuric acid solution and are taken through a current‚ it may be observed that corrosion products are formed around the electrodes‚ to differing degrees. The reason for this is because when a uniform voltage is applied across the series of interconnected electrodes in the acid solution different potentials are obtained at each electrode and hence different electrochemical reactions take place. The products of these

The fixed orthodontic appliances are subjected to corrosive damage which acts to degrade the physical properties and increase the potential for failure. The oral environment because of its enzymatic phenomenon is an ideal climate for corrosive attack of orthodontic appliances. This gradual destruction of materials resulting from chemical reactions can have several adverse effects such as the release of elements from metals‚ roughening of wire surface‚ and weakening of appliances‚ which can lead

1 Introduction This assignment provides the study on Disruptive Innovation using Clayton Christensen’s framework. Apart from this‚ this assignment also tells how the companies should react to the upcoming technologies and what should be the course of action for the same. 1.1 Innovation There is no specific definition for innovation as such. But‚ according to me‚ innovation is creating something new or changing the old to achieve the competitive advantage and meet the increasing customer demands
