The ball and plate system is.an inherently nonlinear under actuated benchmark system used for validating the performance of various control schemes. A mathematical model depicting the dynamics close to that of the system is very much required for such a test bed. In this correspondence, the complete nonlinear model, a simplified nonlinear model, and a linearized model of the ball and plate system are developed. The system comprises.a ball and plate mechanism and a rotary servo unit. The ball and plate mechanism is modelled using the Euler–Lagrange method, whereas the rotary servo subsystem is modelled from the first principles. The nonlinear model of the combined system is developed by including the dynamics of the servo motor with gear and rolling resis.ance between the ball and the plate. The simplified nonlinear model of the system is obtained with suitable assumptions. The model is linearized around the operating point using the Jacobian. The validity of the developed models is investigated through correlation function analysis. The open-loop response of the three models, viz., nonlinear, simplified nonlinear, and linearized models, is.analyzed in the MATLAB/simulink platform. since the open-loop system is uns.able, the experimental validation of the model is performed with a double-loop PsO (particle s.arm optimization) PID control scheme.

In the last four decades,the importance of non-alcoholic fatty liver dis.ase(NAFLD)has increased as the etiology of cirrhosis in the world and associated hepatocellular cancer(HCC).Recently,the terminology has been changed to metabolic-dysfunction associated steatotic liver dis.ase(MAsLD)(1).Importantly,a recent validation of the criteria revealed that 99.5%of NAFLD patients in a large cohort of sweden met the MAsLD criteria(2).The authors concluded that previous natural history data can be used.

A rudimentary aspect of human life is the health of an individual,and most commonly the wellbeing is impacted in a colos.al manner through the consumption of food. The intake of calories therefore is.a crucial aspect that must be meticulously monitored. Various health gremlins can be largely circumvented when there is.a subs.antial balance in the number of calories ingested versus the quantity of calories *** food calorie estimation is.a popular domain of res.arch in recent times.and is meticulously analyzed through various image processing and machine learning techniques. However,the need to scrutinize and evaluate the calorie estimation through various platforms.and algorithmic approaches.aids in providing a deeper insight on the bottlenecks involved,and in improvising the bariatric health of an individual. This paper pivots on comprehending a juxtaposed approach of food calorie estimation through the use of employing Convolution Neural Network(CNN)incorporated in Internet of Things(IoT),and using the Django framework in Python,along with query rule-based training to analyze the subsequent actions to be followed post the consumption of food calories in the constructed webpage. The comparative analysis of the food calorie estimate implemented in both platforms is.analyzed for the swiftness of identification,error rate and classification accuracy to appropriately determine the optimal method of use. The simulation results for IoT are carried out using the Raspberry Pi4B model,while the Anaconda prompt is used to run the server holding the web page.
