Modelling on vibration of skew plate with thickness and temperature variation
The present model describes the vibrational analysis of skew (parallelogram) plate made up of non-homogeneous material with variable thickness and temperature on clamped edges. One dimensional thickness and two-dimensional temperature variation is taken into consideration. The non-homogeneity of the plate varies circular in one dimension. The governing differential equation of motion for vibration analysis is solved by using Rayleigh Ritz technique and time period is calculated for the combination of different variation of plate parameters. The obtained results are presented in tabular form
Vibration of rectangle plate with variable density and Poisson’s ratio
The effect of variation in density and Poisson’s ratio is examined, on the vibration of rectangle plate with linear variable thickness. Bi parabolic temperature effect on the plate is also studied and vibrational modes of rectangular plate is calculated by using Rayleigh Ritz method. Authors also compared the present finding with the published results
Effect of linear variation in density and circular variation in Poisson’s ratio on time period of vibration of rectangular plate
In this paper, a theoretical analysis is carried out to investigate the effect of linear variation in density and circular variation in Poisson’s ratio on time period of frequency modes of rectangular plate with variable thickness under temperature field. The thickness variation is considered to be circular and temperature variation on the plate is assumed to be bi-linear. Rayleigh Ritz method is used to solve the differential equation. All the results (time period for first two modes of vibration) are presented with the help of tables
Natural vibration of tapered rectangular plate with exponential variation in non homogeneity
In this paper, authors studied the natural vibration of tapered non homogeneous rectangular plate on clamped edges. For tapering in plate, authors considered circular variation in thickness and for non-homogeneity (in plate’s material) Poisson’s ratio varies exponentially. Bilinear temperature (linear along both the axes) variation on the plate is being viewed. Rayleigh Ritz method is used to solve differential equation of motion. All the results are presented with the help of tables and graphs. A comparison of results is also given to support the present study
Nations within a nation: variations in epidemiological transition across the states of India, 1990–2016 in the Global Burden of Disease Study
18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016
DWEDDEEC: Distance Aware Waiting based EDDEEC Protocol for Hetrogeneous WSNS
As Wireless Sensor Networks (WSNs) contain numerous sensor nodes containing limited battery power that collect and transmit the data collected from all the nodes towards the Base Station which needs much energy utilization. There are several routing protocols which are already proposed under this consideration attaining effectiveness of energy in heterogeneous circumstances. Although, every protocol is unsuitable for heterogeneous WSNs. Efficiency of WSNs declines as varying the heterogeneity of sensor nodes. Though EDDEEC has depicted quite considerable outcomes compared to already developed existing WSNs protocols but it has ignore the utilization of waiting time of node to become cluster heads (CHs). Therefore might a few nodes will not turn out to be CHs for a very long time still they contain more confidence to become CHs. Therefore to conquer this issue we have used a waiting counter called . is then total number of waiting rounds for a given node to become CH. It will generate a +ve value that will constantly amplify the node to T (n) value for a specified node to become CH. So it will produce more optimized CHs. For getting the better results more we have used the minimum allowed distance (MDCH) between two CHs to cover the sensor field in the most proficient manner
