Background: COVID-19 crisis has increased the depression, anxiety and mental stress burden. Stressful situations and environments like
quarantine can further exacerbate these conditions. We studied association of depression, anxiety, stress and the lived experience on outlook
towards adherence to preventive practices.
Methods: A simultaneous (Quant + Qual) mixed method study was carried out in 228 persons in facility based quarantine in a rural area of India.
Depression, Anxiety and Stress Scale 21(DASS 21) and associated adherence behaviours to preventive measures were inquired into. Interviews
about lived experiences and a Focus Group Discussion was conducted to gain quality insights.
Results: Anxiety levels were higher with 19.7% reporting very severe anxiety, 11% reporting severe and 21.5% reporting moderate anxiety. Non
adherence to wearing masks (37.3%) and social distancing (34.6%) elicited higher depression, anxiety and stress scores whereas non adherence to
hand hygiene reported in 43.8% was not associated with signicant rise in anxiety scores.
Conclusions: Quarantined individuals suffering from depression, anxiety and stress require counselling. This time should also be used as an
opportunity to reinforce proper preventive behaviours found lacking among the quarantined as the experience makes them introspective and more
amenable to change.
In this paper different design scheme for a PID controller have been introduced for a single axis of a quadcopter. This type of model is also known as PVTOL (planar vertical take-off and landing) system. The PVTOL system possess complicated roll control schemes, nonlinearity, low stability and is a second order type process. This paper aims to present a comparison between different controllers used in a dynamic model of a PVTOL platform. Performance comparison of classical Zeigler Nicholas (ZN-PID) is done against Genetic Algorithm (GA) based controller optimization. The results are obtained using MATLAB and SIMULINK, the (ZN-PID) and (GA) based controller is designed for disturbance rejection, close loop response and set point tracking.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
