Gravitational Influence on Human Living Systems and the Evolution of Species on Earth
( MDPI , 2021 , Article Review)Gravity constituted the only constant environmental parameter, during the evolutionary period of living matter on Earth. However, whether gravity has affected the evolution of species, and its impact is still ongoing. The ... -
Gravitational Instability of a Radiating Gas Cloud with Variable streams
( Qatar University , 2001 , Article)The self-gravitating instability of a radiating gas cloud possessing variable streams is investigated. The self-gravitating force is destabilizing according to restrictions, the radiation has a strong stabilizing influence ... -
Gravitational weighted fuzzy c-means with application on multispectral image segmentation
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper presents a novel clustering approach based on the classic Fuzzy c-means algorithm. The approach is inspired from the concept of interaction between objects in physics. Each data point is regarded as a particle. ... -
Gravitohydrodynamic Instability Of A Streaming Fluid Cylinder
( Qatar University , 1996 , Article)The capillary-gravitodynamic instability of a self-gravitating fluid cylinder (radius R«) dispersed in a self-gravitating medium of negligible motion has been developed. General stability criteria are derived, upon utilizing ... -
