Combustion synthesis and photoluminescence properties of CaAl2O4 : Eu2+, Y3+ based long lasting nanophosphors
(KOREAN ASSOC CRYSTAL GROWTH, INCSUNGDONG POST OFFICE, P O BOX 27, SEOUL 133-600, SOUTH KOREA, 2014)
Phosphorescent materials are known as long lasting materials including lanthanide atom doped nano particles which recently have found wide application field. Phosphorescent, classically, is the materials which have light ...
Existence of Countably Many Positive Solutions for Nonlinear Boundary Value Problems on Time Scales
(NATURAL SCIENCES PUBLISHING CORP-NSPPO BOX 32038, ISA TOWN 00000, BAHRAIN, 2014)
In this paper, we consider the existence of countably many positive solutions for nonlinear singular boundary value problem on time scales. By using the fixed-point index theory and a new fixed-point theorem in cones, the ...
A modeling and control approach to advanced nuclear power plants with gas turbines
(PERGAMON-ELSEVIER, 2013)
Advanced nuclear power plants are currently being proposed with a number of various designs. However,
there is a lack of modeling and control strategies to deal with load following operations. This research
investigates ...
Robust reactivity, neutron source, and precursor estimators for nuclear reactors
(ELSEVIER SCIENCE SAPO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2013)
Reactivity, precursor concentration, and external neutron source strength determine control, operation and performance of nuclear reactors. These main reactor quantities are not directly measurable and must be calculated ...
Amorphous carbon nitride (C3N4)
(ELSEVIER, 2024)
This detailed investigation employs an ab initio approach to explore the atomic structure and electronic properties of an amorphous carbon nitride (C3N4) model. The model, designed with an exact 3:4 ratio, is based on ...
Transition towards the sustainable development: unraveling the effects of mineral markets, Belt & Road Initiative, and the Paris Agreement on green economic growth
(ELSEVIER, 2024)
The Agenda 2030 strongly emphasizes implementing effective and equitable measures to address the urgent
challenge of global warming, primarily driven by unsustainable fossil-fuel combustion, and one of its core focuses
is ...
Multi-focus image fusion by using swarm and physics based metaheuristic algorithms: a comparative study with archimedes, atomic orbital search, equilibrium, particle swarm, artificial bee colony and jellyfish search optimizers
(SPRINGER, 2023)
The lenses focus only on the objects at a specific distance when an image is captured, the objects at other distances look blurred. This is referred to as the limited depth of field problem, and several attempts exist to ...
Investigating the Tradeoff Between the MMF Distortion and End Turn Length of a 2-Pole Line Start SynRM Performance
(Institute for Ionics, 2023)
Conventional 2-pole AC machine windings have long end windings and generate harmonics, which increase losses and
reduce torque density. This study investigates the performance tradeoff between the level of distortion (THD) ...
Matching variants for functional characterization of genetic variants
(Genetics Society of America, 2023)
Rapid and low-cost sequencing, as well as computer analysis, have facilitated the diagnosis of many genetic diseases, resulting in a substantial rise in the number of disease-associated genes. However, genetic diagnosis ...
An effective colorectal polyp classification for histopathological images based on supervised contrastive learning
(ELSEVIER, 2024)
Early detection of colon adenomatous polyps is pivotal in reducing colon cancer risk. In this context, accurately distinguishing between adenomatous polyp subtypes, especially tubular and tubulovillous, from hyperplastic ...
