In this paper, we develop a novel theoretical model named “Social distancing SEIQR model” to control the spread of infection by combining both quarantine and social distancing explicitly based on the real cases that observed where medical equipment and others resources are limited. COVID-19 is …..

Palindromic, periodic and Möbius Rubik’s snakes

October 19, 2021 Engineering No Comments

A Rubik’s Snake is an interesting toy which can be thought as a serial chain with applications in the construction of reconfigurable modular robots. In this paper, we present some theorems related to a Rubik’s snake with palindromic, periodic and Möbius properties. Examples are given …..

Gumbel – pareto distribution and it’s applications in modeling COVID data

A new distribution namely Gumbel- Pareto from Gumbel -X family1 is introduced. Some properties including moments and order statistics are studied. A reliability measure for stress – strength analysis is derived. The method of maximum likelihood is proposed for estimating the distribution parameters.The flexibility of …..

Superior outcomes of Volumetric Modulated Arc Therapy (VMAT) in the palliation of skull metastases of multiple myeloma: a case report

October 11, 2021 Radiology & Cancer Therapy No Comments

Palliative radiotherapy (RT) is often given to symptomatic sites of multiple myeloma (MM). Three-dimensional conformal radiotherapy (3DCRT) is often the main modality due its efficiency but it may involve irradiation volumes which include organs at risk (OARs). A case of end-stage MM with innumerable skull …..
