An Effective Noise Removal Technique for Digital Images using Super Pixel Classification

2021-09-15T04:49:59+00:00

Good learning image priors from the noise corrupted images or clean natural images are very important in preserving the local edge and texture regions while denoising images. This paper exhibits a novel picture denouncing calculation in view of super pixel bunching and inadequate portrayal, named as the super pixel grouping and scanty portrayal (SC-SR) calculation. Rather than most existing techniques, the proposed calculation additionally learns picture nonlocal self-likeness (NSS) earlier with mid-level visual prompts by means of super pixel grouping by the inadequate subspace bunching strategy. As the super pixel edges clung to the picture edges and mirrored the picture basic highlights, auxiliary and edge priors were considered for a superior investigation of the NSS earlier. Next, each comparable super pixel district was viewed as a looking window to look for the principal L most comparative patches to every nearby fix inside it. For each comparative super pixel area, a particular lexicon was found out to acquire the underlying inadequate coefficient of each fix. Also, to advance the viability of the scanty coefficient for each fix, a weighted inadequate coding model was built under a requirement of weighted normal meager coefficient of the primary L most comparable patches. Exploratory outcomes showed that the proposed calculation accomplished exceptionally aggressive denoising execution, particularly in picture edges and fine structure conservation in examination with best-in-class denoising calculations.

ANALYSIS ON RESEARCH ON THE TEACHING MODE REFORM OF PSYCHOLOGY UNDER EDUCATIONAL PSYCHOLOGY

2021-12-22T09:29:29+00:00

Psychological education and teaching methods have a significant impact on educational
outcomes; therefore, in a changing educational environment and with shifting educational
objectives, it is important to actively promote education and teaching method reform.
Observations of educational and teaching practises at this point show that as network
applications become more widely used and computer technology becomes more widely
integrated into educational settings, the methods and modes of instruction are becoming
increasingly diverse. But it comes with a host of complications. Increasing numbers of college
students are hooked on the virtual world of the Internet. As a result, they suffer from mental and
physical health issues such as depression, confusion, and autism, and they may even turn to
crime as a means of coping with their situation. In this article, examples of educational
psychology's opportunities and challenges in colleges and universities under the influence of
information technology will be discussed. The author's goal is to help college students better
understand their own mental health.

Dispatching Economically Restricted Loads Using a Biogeography- Based Optimization Algorithm and an Improved Harmony Search Algorithm

2021-12-30T15:30:10+00:00

HSA, IHS, and BBO algorithms are compared in this work for handling restricted economic load
dispatch issues in a power system with a limited number of available resources. New solution
vectors are generated using the IHS algorithm, which makes use of numerous harmony memory
consideration rates and dynamic pitch adjustment rates. They were tested in a test system with
twenty producing units with ramp rate restrictions and valve point loading constraints, and the
algorithms worked well. IHS approach outperforms both Harmony search and Biogeographybased
optimization algorithm in terms of total fuel cost and convergence characteristics, as
shown by the simulation results.

Quantized thermal conductance in metallic heterojunctions

2021-12-30T15:31:40+00:00

It is critical to understand how charge and heat are transferred at the nanoscale in order
to create next-generation electronics and high-efficiency energy-harvesting devices for
future applications. When it comes to probing the quantum limitations of transport,
metallic atomic-size contacts are perfect systems. Several recent studies have shown that
the thermal conductance and electrical conductance of gold atomic contacts may be
quantized at room temperature. However, the quick breaking dynamics of metallic
junctions at room temperature, which might surpass the average reaction time of the
thermal measurement, represents a significant experimental barrier in such studies. An
integrated heater that also serves as a thermometer is used in this break-junction
arrangement, which combines Scanning Tunneling Microscopy with suspended
microelectromechanical systems with a gold-covered membrane. Other metals, including
as Pt, PtIr, and W, were used as tip materials instead of gold to demonstrate heat transfer
measurements across single gold atomic contacts. The relationship between thermal
conductivity and contact size is investigated as a function of the contact size and the
materials employed. In our experiments, we have discovered that by utilising Pt and Pt-
Ir tips, we may increase the mechanical stability and likelihood of creating single Au
atomic connections. In the next section, we demonstrate the quantization of electrical
and thermal conductances, followed by a demonstration of the Wiedemann-Franz law at
the atomic scale. We anticipate that these discoveries will expand the flexibility of
experimental methodologies for examining heat transport in metallic quantum point
contacts, as well as the ability to investigate the thermal characteristics of molecular
junctions.

Computational Fluid Dynamics Strut Flame Holder Efficiency ffor Supersonic Combustion

2022-04-11T17:51:19+00:00

For hypersonic vehicles, the ramjet engine's supersonic burning process is considered a suitable propulsion technology. The
flow in the combustor has an extremely short residence time (milliseconds) due to the supersonic combustion. Fuel-air mixing and
combustion efficiency have been evaluated using both normal and tangential fuel injection.. Shocks and vorticity created in the combustor
keep the flame in place and prolong its stay in there. For CFD analysis, the commercial numerical programme ANSYS FLUENT 15 i s
used. ICEM CFD is used for geometry and meshing, whereas FLUENT is used for analysis. Simulated flow field of hydrogen-fueled
scramjet combustor has been used to the finite-rate/eddy-dissipation reaction model. Fuel injector count is being investigated at different
Combustor inlets with a Mach number of 2.0 and fuel being introduced under sonic circumstances. Combustion efficiency is measured as
a function of the total mass of H2O in the combustor. Aiming for a better fuel-air combination in the combustion chamber and achieving
optimum combustion efficiency were the main goals of the work done.

Curriculum Implementation from the Perspective of a Language Teacher

2023-04-11T10:38:58+00:00

The concept of curriculum is defined in various ways. But the perceptions of teachers about the concept of curriculum can determine the effectiveness of teaching-learning process in a positive or negative way (Kyriakides, 1997). Though the involvement of students, parents, and school principals is important (Doll, 2008), teachers, who constitute one of the basic groups, should take an active role in curriculum development (Carl, 2005). Since the curriculum is put into practice by teachers in the classroom (Ornstein & Hunkins, 2012), it is reasonable to benefit from their perceptions (Marsh & Willis, 2003). The meaning attributed to the concept of curriculum by teachers includes important information for curriculum development (Yurdakul, 2015). This paper majorly examines curriculum from the perspective of a language teacher. It aims to find out the appropriateness of the given explanation on curriculum in Oxford Advanced Learner’s Dictionary, 2020 and describes the concerns of curriculum and compares them with the given explanation. It also tries to answer the question like “does the given explanation on curriculum take care of all its basic features?” After a thorough discussion on curriculum, an attempt has been made to justify the relevance of the process approach to curriculum development. And finally, three Skilbeck’s models on curriculum have been compared to find out which of these would be associated with product approach and which of these with process approach.
