Oil pollution is one of the major critical risks to Egypt’s marine environment due heavy traffic caused by shipping in Suez Canal and exploration production crude oil. Indeed, such frequent oil cases harm ecosystem creates pressure on socio-economic activities within coastal economic zone Egypt. Limited data availability obstacles precise monitoring ability alert agency take any necessary actio...

This paper proposes a novel multi-target tracking method which jointly solves a data association problem using images from multiple cameras. In this work, the spatiotemporal data association problem is formulated as a multidimensional assignment problem (MDA). To achieve a fast, efficient, and easily implementable approximation algorithm, we solve the MDA problem approximately by solving a sequ...

In cities with tall buildings, emergency responders need an accurate floor level location to find 911 callers quickly. We introduce a system to estimate a victim’s floor level via their mobile device’s sensor data in a two-step process. First, we train a neural network to determine when a smartphone enters or exits a building via GPS signal changes. Second, we use a barometer equipped smartphon...

Light and transmission electron microscopic observations of the venom gland of the blue coral snake revealed a main venom gland and a long duct. The main secretory cell showed characteristic features of a protein secreting cell, with small microvilli, and a cytoplasm containing vacuoles and vesicles. Another type of "dark cell" and a third type of "basal cell" were also seen. "Nerve terminals" ...
