Background: IUCD is a temporary method of contraception in use for many years. Our main objective is to find the acceptance of (postplacental intrauterine contraceptive device) PPIUCD in recent years. Methods: Retrospective Analysis was carried out to collect information regarding IUCD insertion in all women delivered at semi urban based medical college in Tamil Nadu from April 2014 to March 2016. Results: Total women delivered in our hospital were 20949 over a period of two years. Two year comparative study revealed significant increase in acceptance of PPIUCD insertion among primipara from 39.1% TO 68.9%. Acceptance of PPIUCD in primipara was 51.6% in first year (April 2014 to March 2015) to 87.8% in second year (April 2015 to March 2016).Most of the women were in the age group of 20 to 29 years (81.5%). Conclusions: The present study being retrospective analysis showed sudden increase in coverage rate of PPIUCD from 2014-2015 to 2015-2016. Though the patients were motivated in the same way throughout the period, training and motivation given to the staff nurses and duty doctors in the labour ward for PPIUCD insertion and daily review instead of weekly had brought the significant increase in the coverage. This clearly shows the role of service provider in the success of a national program though acceptor is always ready in most of the times.

Background: Tubal sterilisation is a permanent method of contraception in use for many years. Main objective of our study is to find the acceptance of permanent method of tubal sterilisation in women delivering in a semi-urban based medical college hospital. Methods: Retrospective analysis was carried to find the number of women undergoing tubal sterilisation in our hospital for period of one year from April 2015 to March 2016. Results: Total women delivered over a period of one year were 10959 out of them 2619 women underwent tubal sterilisation. Analysis showed acceptance was high when combined with lower segment cesarian section (LSCS) and more among women in the age of 20-29 years. Conclusions: The present study showed the acceptance of tubal sterilisation following vaginal delivery to undergo mini lap is still low compared to concurrent sterilisation with LSCS. High order births are still prevalent in semi-urban based hospitals. Not only motivation, also regular review of registers that update the eligible couples, identification of complications and timely referral to higher centers will help in achieving the goal of bringing down the number of high order birth which in turn will reducing the maternal and perinatal mortality and morbidity.

The Flying Capacitor Multicell Inverter (FCMI) possesses an inherent balancing of voltage across the capacitors and it is used to distribute the input voltage and minimize the voltage stress. This FCMI's RMS is first controlled with fuzzy controller and the outputs are analyzed, then a suitable Model Predictive Controller (MPC) is considered to be in command of the RMS voltage of the Flying Capacitor Multicell Inverter and the outputs are measured up to with fuzzy controlled FCMI. The controller (Fuzzy and MPC) are considered for different levels of FCMI circuits and has been found that MPC controller gives better performance as compared to the fuzzy controlled FCMI. To weigh against the performance of Fuzzy and MPC controllers the Rise time, Settling time, Overshoot, Peak and Peak time are taken as comparison parameters and the comparison chart is presented for analysis.

Reduced Voltage Source Multicell Converters are one of the best alternative for Capacitor Multicell Converter, as the former uses only a single voltage source as compared to the later which uses two voltage sources for a single phase converter. In this paper three different levels (i.e., 5 level, 7 level and 9 level) of reduced voltage source multicell converters are analyzed by taking THD as an analyzing parameter, from the analysis it can be inferred that the THD decreases with increase in the number of levels. Suitable fuzzy controllers are designed for the different levels of reduced voltage source multicell converters to control the RMS output voltage. The performance of the fuzzy controllers for the different levels of reduced voltage source multicell converters are analyzed.
