The design of simulated antenna is shown in Fig. 3.1. As can be seen from the figure‚ the Yagi-Uda antenna was built on a FR4 substrate (εr = 4.4) with the thickness of 1.6 mm. The design consists of one director element‚ a driven element and a ground plane acting as a reflector. To enhance the gain of the antenna coupling microstrips and metal plate were placed‚ that focus the entire beam towards a driven dipole.

ELEMENTS OF PSYCHOPHYSICS Sections VII and XIV Gustav Theodor Fechner (1860 - 1912) VII THE MEASUREMENT OF SENSATION [...] Weber’s law‚ that equal relative increments of stimuli are proportional to equal increments of sensation‚ is‚ in consideration of its generality and the wide limits within which it is absolutely or approximately valid‚ to be considered fundamental for psychic measurement. There are‚ however‚ limits to its validity as well as complications‚ which we shall have carefully

Recent air pollution rise in delhi heavy smog enveloped New Delhi last November. One year later‚ levels of particulate matter have hit nearly 20 times what the government considers a standard for health. Inhalable waste in the form of particulate matter 10‚ or PM10‚ hit 1‚940 micrograms per cubic meter in the city whereas The Delhi Pollution Control Committee’s standard for healthy conditions is 100 micrograms per cubic meter or lower. Air quality often deteriorates during the Diwali festival‚
