Dhansak ("Dhan" is Persian/Urdu for "seed"- referring to grains or legumes; "Sak" (derived from Gujarati "shaak" meaning vegetable greens or cooked vegetables). The Gujarati element of the recipe is the liberal use of a variety of Indian spices and condiments, in contrast to the more mellow Iranian recipes. In Parsi homes, dhansak is traditionally made on Sundays owing to the long preparation time required to cook the lentils and vegetables into a mush (in the days before pressure cooking was employed). Dhansak is also always had on the fourth day after the death of a near one. There is no meat
Pulse compression The SNR is proportional to pulse duration formula_30, if other parameters are held constant. This introduces a tradeoff: increasing formula_30 improves the SNR, but reduces the resolution, and vice versa. How can one have a large enough pulse (to still have a good SNR at the receiver) without poor resolution? This is where pulse compression enters the picture. The basic principle is the following: In radar or sonar applications, linear chirps are the most typically used signals to achieve pulse compression. The pulse being of finite length, the amplitude is a rectangle function. If the transmitted signal has a duration
