Students Impression About Using Mobile Phones in Classroom
(
Kassel University Press GmbH
, 2020 , Article)
Mobile phones are widely used by university students and there is a controversial topic whether students should be able to use them freely during lectures. A survey was distributed seeking student opinions on using mobile ...
Herd immunity against severe acute respiratory syndrome coronavirus 2 infection in 10 communities, qatar
(
Centers for Disease Control and Prevention (CDC)
, 2021 , Article)
We investigated what proportion of the population acquired severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2) infection and whether the herd immunity threshold has been reached in 10 communities in Qatar. The ...
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 motion of a point vortex in multiply-connected polygonal domains
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2020 , Article)
We study the motion of a single point vortex in simply-and multiply-connected polygonal domains. In the case of multiply-connected domains, the polygonal obstacles can be viewed as the cross-sections of 3D polygonal ...
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 ...
First principle study of transition metals codoped MoS2 as a gas sensor for the detection of NO and NO2 gases
(
Elsevier B.V.
, 2021 , Article)
Exposure to nitrogen oxides (NOx) has been reported to seriously affect the respiratory systems. More precisely, breathing NOx may lead to the appearance of asthma symptoms, and may also result in the infection with asthma ...
Efficient monitoring of coefficient of variation with an application to chemical reactor process
(
John Wiley and Sons Ltd
, 2021 , Article)
Control chart is a useful tool to monitor the performance of the industrial or production processes. Control charts are mostly adopted to detect unfavorable variations in process location (mean) and dispersion (standard ...
Numerical Simulation of Magnetic Dipole Flow Over a Stretching Sheet in the Presence of Non-Uniform Heat Source/Sink
(
Frontiers Media
, 2021 , Article)
The main objective of current communication is to present a mathematical model and numerical simulation for momentum and heat transference characteristics of Maxwell nanofluid flow over a stretching sheet. Further, magnetic ...
On designing an assorted control charting approach to monitor process dispersion: an application to hard-bake process
(
Taylor and Francis Ltd.
, 2020 , Article)
The monitoring of process variability is an important feature to get optimal output from a process. Control charts are vital tools used for efficient process monitoring. The commonly used types of charts include Shewhart, ...
Simulation of natural convective heat transfer and entropy generation of nanoparticles around two spheres in horizontal arrangement
(
Elsevier
, 2021 , Article)
Herein, laminar convective heat transfer from two horizontally arranged spheres has been evaluated by using numerical models inside water-based fluids incorporated with alumina (Al2O3), copper oxide (CuO), and copper (Cu) ...
