In areas where the maternal mortality is low, there is a need to shift focus to maternal near-miss cases or SAMM, which is a useful adjunct to maternal death enquiries.

Country’s economy depend on well-maintained roads as they are major means of transportation. It becomes essential to identify pothole and humps in order to avoid accidents and damages to the vehicles that is caused because of distress to drivers and also to save fuel consumption. In this regard, this work presents a simple solution to detect potholes and humps and hence avoid accidents and help drivers. Potholes are detected using Image Processing Technique and Ultrasonic Sensors are used to detect humps. Controlling device used is Raspberry Pi. The system acquires the geographical position of potholes using Wi-Fi and transmits it to authorities to take corrective measures

Electric vehicles are in demand in recent days due to depleting conventional energy resources. Electric vehicles which are environmental friendly are set to increase on road in coming days. The Electric vehicles which consist of electric drive systems are made up of electric motors, inverters and batteries. There is a need to increase their output quality while decreasing their size and cost. The multilevel inverter plays a vital role in improving the quality of the output voltage of the inverter. This paper presents the implementation of Elliptical Phase Disposition Pulse Width Modulation (EPD PWM) technique for higher level of Cascaded H-Bridge Multi Level Inverter (CHBMLI). The performance of 5, 7 and 9-level CHBMLI with proposed EPD PWM scheme is analyzed for three-phase RL-load. The simulation results prove that the voltage %THD reduces from 28.09 to 12.85 to 9.69 and current %THD reduces from 25.58 to 10.22 to 9.42 as the number of inverter output level increases from 5-7-9 level respectively. The simulation is carried out on MATLAB/ SIMULINK platform and the results were compared with conventional method to validate the proposed scheme. The simulation results prove that the novel EPD-PWM technique can be used to effectively control the CBHMLI.
