Dynamic Analysis of HSDB System and Evaluation of Boundary Non-linearity through Experiments

This paper deals with mechanical design and development of high speed digital board (HSDB) system which consists of printed circuit board (PCB) with all electronic components packaged inside the cavity for military application. The military environment poses a variety of extreme dynamic loading conditions, namely, quasi static, vibration, shock and acoustic loads that can seriously degrade or even cause failure of electronics. The vibrational requirement for the HSDB system is that the natural frequency should be more than 200 Hz and sustain power spectrum density of 14.8 Grms in the overall spectrum. Structural integrity of HSDB is studied in detail using finite element analysis (FEA) tool against the dynamic loads and configured the system. Experimental vibration tests are conducted on HSDB with the help of vibration shaker and validated the FE results. The natural frequency and maximum acceleration response computed from vibration tests for the configured design were found. The finite element results show a good correlation with the experiment results for the same boundary conditions. In case of fitment scenario of HSDB system, it is observed that the influence of boundary non-linearity during experiments. This influence of boundary non-linearity is evaluated to obtain the closeout of random vibration simulation results

Exploring the Enhanced Performance of a Static Synchronous Compensator with a Super-Capacitor in Power Networks

The use of a super-capacitor as a storage device integrated with a Voltage source converter-based shunt-connected Static Synchronous Compensator (STATCOM) is proposed for improving the STATCOM performance during sudden large disturbances in a power network. The super-capacitor was applied across the STATCOM capacitor during the disturbance condition. MATLAB simulations were carried out for the verification of a secondary function of the STATCOM like oscillation damping, transient stability improvement, and security of the power network with the storage device. The validation of the proposed super-capacitor was carried out in MATLAB

A study to assess receipt and utilization of janani suraksha yojana cash incentive among mothers in urban slums of Raipur city, Chhattisgarh, India

Background: Janani Suraksha Yojana (JSY) replaces the National Maternity Benefit Scheme. It was launched by the Government of India in April 2005. The aim was to reduce maternal and neonatal mortality by increasing institutional delivery by providing cash incentive to the beneficiaries as well as the link worker ASHA. Objectives of this study was to assess receipt of Janani Suraksha Yojana (JSY) cash incentive and to assess fields of utilization of Janani Suraksha Yojana (JSY) cash incentive.Methods: A Community based cross-sectional study was conducted among 384 mothers delivered within last one year in urban slum of Raipur city. Study centre was department of community medicine, Pt. J.N.M. medical college Raipur, Chhattisgarh. A pre-designed and pre-tested questionnaire was used to interview the study subjects.Results: Out of total 384 study subject’s cheque of JSY cash incentive was received by 70.83%. All (100%) beneficiaries who received cheque was stipulated amount as per JSY guideline. Reasons for not receiving cheque was no availability of BPL card for those who delivered in accredited private health facility. Other reasons were absconded after delivery, unaware of cash incentive, did not go back to get the cheque when called later, patient shifted to another ward. None of the study subjects who delivered at home received the cash incentive cheque. Realization of cheque was not done by 22.79% of study subjects due to complex procedure to open an account in bank. Cash incentive money was utilized in neonatal care, drugs, food, household activities and some deposited in bank.Conclusions: JSY scheme is definitely functioning well in terms of providing cash incentive cheque of JSY on delivery in Government Health facility. There is need to simplify the procedure to open an account so that beneficiaries can avail cash incentive money. There is need to address the problems to receive cheque in home delivery and accredited Private health facility in addition to motivation for institutional delivery

Thermoluminescence and Mechanoluminescence studies of (Cd0.95 Zn0.05)S: Ag doped phosphor

Through the execution of experimental investigation, mechanoluminescence of (Cd,Zn)S: Ag phosphor was studied which is synthesized by solid state reaction. In the observation, the peak value of ML depends on different concentration. It is seen that ML intensity increases with Ag ion concentration in (Cd, Zn)S phosphor. The peak value of TL depends on the different UV-irradiation time. It is seen that as UV-irradiation exposure increases the TL intensity also increases

Animal welfare attitudes: Effects of gender and diet in university samples from 22 countries

Animal Welfare Attitudes (AWA) are defined as human attitudes towards the welfare of animals in different dimensions and settings. Demographic factors, such as age and gender are associated with AWA. The aim of this study was to assess gender differences among university students in a large convenience sample from twenty-two nations in AWA. A total of 7914 people participated in the study (5155 women, 2711 men, 48 diverse). Participants completed a questionnaire that collected demographic data, typical diet and responses to the Composite Respect for Animals Scale Short version (CRAS-S). In addition, we used a measure of gender empowerment from the Human Development Report. The largest variance in AWA was explained by diet, followed by country and gender. In terms of diet, 6385 participants reported to be omnivores, 296 as pescatarian, 637 ate a vegetarian diet and 434 were vegans (n = 162 without answer). Diet was related with CRAS-S scores; people with a vegan diet scored higher in AWA than omnivores. Women scored significantly higher on AWA than men. Furthermore, gender differences in AWA increased as gender inequality decreased

Evaluation of the Codal Provision for Asymmetric Building

The research on asymmetric buildings has been extensive primarily focusing on the stability of a structure when subjected to earthquake. Based on them numerous guidelines are laid out for to make sure safety. I have during this paper tried to guage the effectiveness of the rules provided within the IS: 1893 (2000). Asymmetric buildings are more common now than they have ever been and their popularity has been growing primarily due to the functionality they provide. Due to the frequent earthquakes that India suffers, being at the junction of two tectonic plates it has become increasingly important to review Indian buildings for seismic safety. The buildings are analyzed supported the effect of torsion which is that the main explanation for damage for Asymmetric Buildings
