The present study is concerned with the propagation of Lamb waves in a homogeneous isotropic thermoelastic micropolar solid with two temperatures bordered with layers or half spaces of inviscid liquid subjected to stress free boundary conditions. The generalized theory of thermoelasticity developed by Lord and Shulman has been used to investigate the problem. The secular equations for symmetric...

Drought is one of the most hazardous natural disasters in terms number people directly affected. An important characteristic drought prolonged absence rainfall relative to long-term average. The intrinsic persistence conditions continuing from month next can be utilized for monitoring and early warning systems. This study sought better understand probabilities baselines two agriculturally regio...

Skew refers to the text which is neither parallel nor at right angles to a specified or implied line.Even a smallest skew occurring in a document image results in the failure of segmentation of characters from words or text lines.It is therefore essential to detect and correct the skew at the preprocessing stage so that the perturbation of skew can be avoided for further processing. In this pap...

The stochastic data envelopment analysis (SDEA) was developed considering the value ofinputs and outputs as random variables. Therefore, statistical distributions play an importantrole in this regard. The skew-normal (SN) distribution is a family of probability densityfunctions that is frequently used in practical situations. In this paper, we assume that the inputand output variables are skew-...
