Driver Drowsiness Detection System: An Approach By Machine Learning Application
The majority of human deaths and injuries are caused by traffic accidents. A
million people worldwide die each year due to traffic accident injuries,
consistent with the World Health Organization. Drivers who do not receive
enough sleep, rest, or who feel weary may fall asleep behind the wheel,
endangering both themselves and other road users. The research on road
accidents specified that major road accidents occur due to drowsiness while
driving. These days, it is observed that tired driving is the main reason to
occur drowsiness. Now, drowsiness becomes the main principle for to increase in
the number of road accidents. This becomes a major issue in a world which is
very important to resolve as soon as possible. The predominant goal of all
devices is to improve the performance to detect drowsiness in real time. Many
devices were developed to detect drowsiness, which depend on different
artificial intelligence algorithms. So, our research is also related to driver
drowsiness detection which can identify the drowsiness of a driver by
identifying the face and then followed by eye tracking. The extracted eye image
is matched with the dataset by the system. With the help of the dataset, the
system detected that if eyes were close for a certain range, it could ring an
alarm to alert the driver and if the eyes were open after the alert, then it
could continue tracking. If the eyes were open then the score that we set
decreased and if the eyes were closed then the score increased. This paper
focus to resolve the problem of drowsiness detection with an accuracy of 80%
and helps to reduce road accidents
Ambient Temperature Based Thermal Aware Energy Efficient ROM Design on FPGA
—Thermal aware design is currently gaining importance in VLSI research domain. In this work, we are going to design thermal aware energy efficient ROM on Virtex-5 FPGA. Ambient Temperature, airflow, and heat sink profile play a significant role in thermal aware hardware design life cycle. Ambient temperature is a temperature of surroundings. Airflow is measured in Linear Feet per Minute (LFM). Medium profile and high profile are two different heat sink profile available in XPower analyzer.When frequency goes from 4.0GHz to 1.0GHz, there is 21.8% reduction in clock power, 75% reduction in I/O Power, 35.6% reduction in leakage power and 53.8% reduction in total power at the same frequency.</jats:p
FPGA Based Low Power ROM Design Using Capacitance Scaling
An ideal capacitor will not dissipate any power, but a real capacitor will have some power dissipation. In this work, we are going to design capacitance scaling based low power ROM design. In order to test the compatibility of this ROM design with latest i7 Processor, we are operating this ROM with frequencies (2.9GHz, 3.3GHz, 3.6GHz, 3.8GHz and 4.0GHz) supported by i7 processor.By using different capacitance there comes is reduction in I/O Power and Total power but not in other Powers like Clock, and Leakage (almost negligible). When capacitance goes from 30pF to 5pF, there is a saving of 28.12% occur in I/O Power, saving of 0.2% occur in Leakage Power, there will be a saving of 11.54% occur in Total Power. This design is implemented on Virtex-5 FPGA using Xilinx ISE and Verilog.</jats:p
