Bitter gourd and Okra were grown in seven thanas in paired plots using both arsenic free and arsenic contaminated irrigation water. Fifty paired plant samples (edible part), collected from both arsenic free(More)
Traffic arrival pattern is an important parameter in delay estimation at signalized intersection. Usually, arrival pattern is assumed to be Poisson distribution. However, it varies widely under different volume-capacity ratio at signalized intersection of an arterial road. Therefore, conventional Poisson model cannot predict traffic pattern properly.
