A Novel and Efficient Method for Computing the Resistance Distance
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
The resistance distance is an intrinsic metric on graphs that have been extensively studied by many physicists and mathematicians. The resistance distance between two vertices of a simple connected graph $G$ is equal to ...
Integrated lab-on-a-chip optical biosensor using ultrathin silicon waveguide soi mmi device
(
MDPI AG
, 2020 , Other)
Waveguides with sub-100 nm thickness offer a promising platform for sensors. We designed and analyzed multimode interference (MMI) devices using these ultrathin platforms for use as biosensors. To verify our design ...

Food waste (FW) is a critical challenge in the Gulf Cooperation Council (GCC). This paper analyzes research dealing with food waste in the GCC countries (viz. Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates). ...
Model robust profile monitoring for the generalized linear mixed model for Phase I analysis
(
John Wiley and Sons Ltd
, 2020 , Conference Paper)
The generalized linear mixed model (GLMM) becomes very popular in profile monitoring, especially when the production processes follow nonnormal distribution. In most of the real-life applications in industry, medicine, ...
A new approach to predicting cryptocurrency returns based on the gold prices with support vector machines during the COVID-19 pandemic using sensor-related data
(
MDPI
, 2021 , Article)
In a real-world situation produced under COVID-19 scenarios, predicting cryptocurrency returns accurately can be challenging. Such a prediction may be helpful to the daily economic and financial market. Unlike forecasting ...
The theta-complete graph Ramsey number r(θk, K5); k = 7, 8, 9
(
Forum-Editrice Universitaria Udinese SRL
, 2021 , Article)
Finding the Ramsey number is an important problem of the well-known
family of the combinatorial problems in Ramsey theory. In this work, we investigate
the Ramsey number r(θs, K5) for s = 7, 8, 9 where θs is the set of ...
Understanding the buffering effect of social media use on anxiety during the COVID-19 pandemic lockdown
(
Springer
, 2021 , Article)
During the COVID-19 outbreak, lockdown measures have been deployed worldwide. In the wake of these measures, internet and social media use has reached unprecedented peaks. We hypothesize that social media can, in the context ...
Isoperimetric properties of condenser capacity
(
Elsevier
, 2021 , Article)
For compact subsets E of the unit disk D we study the capacity of the condenser (D,E) by means of set functionals defined in terms of hyperbolic geometry. In particular, we study experimentally the case of a hyperbolic ...
