Student perspectives on the integration of artificial intelligence into healthcare services
( SAGE Publications Inc. , 2023 , Article)Background: Healthcare workers are often overworked, underfunded, and face many challenges. Integration of artificial intelligence into healthcare service provision can tackle these challenges by relieving burdens on ... -
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 ... -
SU (5) with nonuniversal gaugino masses
( World Scientific Publishing Co. Pte Ltd , 2018 , Article)We explore the sparticle spectroscopy of the supersymmetric SU(5) model with nonuniversal gaugino masses in light of latest experimental searches. We assume that the gaugino mass parameters are independent at the GUT scale. ... -
A superconducting millimetre switch with multiple nano-bridges
( International Symposium on Space Terahertz Technology , 2014 , Conference Paper)In this paper, we describe the design of a planar superconducting on/off switch comprising a high normal resistance nano-bridge deposited across a slotline transmission line. We present preliminary experimental results ... -
A symmetric oscillator with multi-stability and chaotic dynamics: bifurcations, circuit implementation, and impulsive control
( Springer , 2021 , Article)Finding chaotic oscillators with unique properties is a hot topic. In this paper, a symmetric oscillator with multi-stability is proposed. This oscillator has bounded dynamics for any initial conditions. It is also shown ... -
Symmetric oscillator: Special features, realization, and combination synchronization
( MDPI , 2021 , Article)Researchers have recently paid significant attention to special chaotic systems. In this work, we introduce an oscillator with different special features. In addition, the oscillator is symmetrical. The features and ... -
Synchronization and chimeras in a network of photosensitive FitzHugh-Nagumo neurons
( Springer Science and Business Media B.V. , 2021 , Article)Recently, a photosensitive model has been proposed that takes into account nonlinear encoding and responses of photosensitive neurons that are subject to optical signals. In the model, a photocell term has been added to ... -
Synthesis and characterization of Cu-doped TiO2 thin films produced by the inert gas condensation technique
( Institute of Physics Publishing , 2017 , Conference Paper)The bandgap of thin films Cu-doped TiO2 nanoclusters prepared using the inert gas condensation (IGC) technique have been investigated at various Cu contents. The samples were characterized using XRD, SEM/EDS and UV-visible ... -
Synthesis, characterization and biological applications of selenoureas having ferrocene and substituted benzoyl functionalities
( Elsevier Ltd , 2019 , Article)In this article we have comprehensively reported the synthesis, complete chemical characterization (FTIR, multinuclear NMR, single crystal XRD, CHNS, AAS) and biological applications of seventeen ferrocene incorporated ... -
System of variational inequalities with interconnected obstacles
( Taylor and Francis , 2020 , Article)Our objective with this paper is to discuss multi-switching problems, arising as variational inequalities, that models decision under uncertainty. We prove general existence theory through monotone scheme and discuss ... -
T-tetrominoes tiling's Markov chain mixes fast
( Elsevier B.V. , 2018 , Article)Korn and Pak (2007) [3] conjectured that there exists a fully polynomial randomized approximation scheme (fpras) for approximating the number of ways of tiling a 4n x 4m rectangular lattice with T-tetrominoes. Using a flow ... -
Temperature dependence of the pressure induced monoclinic distortion in the spin S=1/2 Shastry–Sutherland compound SrCu2(BO3)2
( Elsevier Ltd , 2014 , Article)We investigate the monoclinic distortion that occurs at 4.7 GPa at room temperature in the frustrated Shastry-Sutherland model quantum magnet SrCu 2(BO3)2 as a function of pressure and temperature by means of powder and ... -
Testing statistical assumptions in research
( wiley , 2019 , Book)This book facilitates researchers in checking the assumptions of statistical tests used in their research by focusing on the importance of checking assumptions in using statistical methods, showing them how to check ... -
TESTING SYMMETRY USING A TRIMMED LONGEST RUN STATISTIC
( Blackwell Publishing Asia Pty Ltd. , 2007 , Article)A distribution-free test is proposed for the symmetry of a continuous distribution about a specified median. The test is based on a longest run statistic on the upper portion of the sequence of ordered �centred� observations ... -
Tests of a diamond field-assisted positron moderator
( Elsevier , 2002 , Conference Paper)Diagnostic studies have been performed on a 70 μm thick diamond film with a view to its development as a possible field-assisted moderator (FAM) for slow positron emission. The film was coated on one side with a 200 nm ... -
The common solutions of the split feasibility problems and fixed point problems
( Springer International Publishing , 2015 , Article)An extraordinary split problem, which can be regarded as a superimposition of the split feasibility problem and the split fixed point problem, is considered. A superimposed algorithm is presented. The analysis technique ... -
The generalized trust-region sub-problem with additional linear inequality constraints-Two convex quadratic relaxations and strong duality
( MDPI AG , 2020 , Article)In this paper, we study the problem of minimizing a general quadratic function subject to a quadratic inequality constraint with a fixed number of additional linear inequality constraints. Under a regularity condition, we ... -
The Ramsey number for two graphs of order 5
( Taylor and Francis Ltd. , 2018 , Article)For two graphs F1 and F2, the Ramsey number R(F1, F2) is the smallest positive integer r such that for every graph G on r vertices, G contains F1 as a subgraph or the complement of G contains F2 as a subgraph. We present ... -
