Visualization of Heliostat Field of Solar Thermal Tower Power Plant Using Virtual Reality (VR) Technologies
No full textAn important part of future global energy depends on the development of the solar industry.
To date, we have noticed the shift from fossil fuels energy towards renewable energy. The past decade
has shown significant progress in computer science, and CAD is increasingly used for design and
development. Visualization of the data generated from the models in the CAD program plays an
important role in the creation of state-of-the-art designs. An important limitation during the design
phase is the visualization of three-dimensional geometry. This article attempts to illustrate the use of
VR technologies in solar thermal power plant development. This article analyzes various strategies
and methods for the visualization of CAD models in virtual reality. Android phone interfaces with
a desktop computer, as well as head movement control strategies, are discussed. It is concluded
that VR technologies can help with visualization, as well as in the development of the field of solar
thermal power plants, having minimal design-related issues

Phytomelatonin: An overview of the importance and mediating functions of melatonin against environmental stresses
No full textRecently, melatonin has gained significant importance in plant research. The presence of melatonin in the plant kingdom has been known since 1995. It is a molecule that is conserved in a wide array of evolutionary distant organisms. Its functions and characteristics have been found to be similar in both plants and animals. The review focuses on the role of melatonin pertaining to physiological functions in higher plants. Melatonin regulates physiological functions regarding auxin activity, root, shoot, and explant growth, activates germination of seeds, promotes rhizogenesis (growth of adventitious and lateral roots), and holds up impelled leaf senescence. Melatonin is a natural bio-stimulant that creates resistance in field crops against various abiotic stress, including heat, chemical pollutants, cold, drought, salinity, and harmful ultra-violet radiation. The full potential of melatonin in regulating physiological functions in higher plants still needs to be explored by further research
Classification of Motor Imagery Based Electroencephalographic Brain Computer Interface Using Brain Connectivity
No full textCLASSIFICATION OF MOTOR IMAGERY BASED ELECTROENCEPHALOGRAPHIC BRAIN COMPUTER INTERFACE USING BRAIN CONNECTIVITY
No full textMotor imagery-based brain-computer interfaces have gained much attention in the past few years. It enables the ability to control external devices, such as prosthetic arms and wheelchairs, using brain activities. Several studies discuss the occurrence of MI actuated signals in primary sensorimotor areas. In contrast, other researchers report the inter-communication of multiple brain regions during motor tasks, thus making it difficult to isolate one or two brain regions where the motor activity takes place. Therefore, a deeper understanding of the behavior of brain neural patterns is important for BCIs to provide more useful and insightful features. Since the execution of motor or cognitive task results in the information exchange of multiple mutually interconnected brain regions

No full textUrdu Dictionary Board has successfully completed the editing and publishing of its 22-volume Urdu dictionary on historical principles, recording the largest number of entries ever enlisted in any Urdu dictionary. But when it was being compiled, Dr Shaukat Sabzwari (1908-1973), one of the editors, had pointed out in an article some of the discrepancies in the proposed manuscript relating to the entries beginning with the letter alif. A copy of this article was handed over by the author to Muhammad Ahsan Khan (Lahore), who was helping the board as an external scholar at that time and continued in the same capacity for about 50 years till the completion of the project in 2010. This article remained unpublished for some 30 years and is now being published through the courtesy of Muhammad Ahsan Khan. It discusses some errors that had crept into the entries given in the proposed manuscript of the dictionary's first volume, which was being in the process of compilation in those days. Some of the errors mentioned persisted in the final draft that was published in 1977, albeit some of them were amended
Peran Strategis Retorika Dakwah dalam Membangun Komunikasi Politik yang Efektif di Masyarakat Muslim Indonesia
No full textThis study aims to analyze the role and urgency of da'wah rhetoric in political communication in Indonesia, with a focus on the context of the Muslim-majority society. As an art of communication, da'wah rhetoric has evolved into a tool for building relationships between leaders and the public, both in spiritual and socio-political dimensions. In this study, the author employs a qualitative approach with a literature review as the primary method, relying on written sources such as books, articles, and previous research to explore the concepts of da'wah rhetoric and its application in political communication. The findings of this study show that da'wah rhetoric not only serves to strengthen religious identity but also functions as a strategic means of shaping public opinion and advancing public agendas, using moral and religious values that can influence the feelings and emotions of the audience. The study discusses three methods of da'wah rhetoric: the method of hikmah (wisdom), mau'izhah hasanah (good advice), and mujadalah billati hiya ahsan (debate in the best manner). The application of these methods is crucial for delivering political messages effectively and persuasively

A modular microscopic smartphone attachment for imaging and quantification of multiple fluorescent microparticles
No full textPortable smartphone-based fluorescent microscopes are becoming popular because of their
capability to carry out some of the major functionalities offered by regular benchtop microscopes
at a fraction of the cost. However, these smartphone-based microscopes still have a lot of
limitations, such as being limited to only one fluorophore, unavailability of multiple
magnifications to name a few. To overcome these challenges, we present the design of a modular
smartphone-based microscopic attachment. Its modular design allows the user to easily swap
between different sets of filters and lenses, thereby providing the choice between multiple
fluorophores and magnification levels. Furthermore, our proposed attachment can image
specimens on glass slides, cover slips, and microfluidic devices. A 1951 USAF resolution test
target was used to quantify the maximum resolution of the microscope which was found to be 3.9
μm.
The performance of the designed smartphone-based fluorescent microscope was then compared
with regular benchtop microscope by counting fluorescent microparticles imaged. We found the
performance of our design to be satisfactory with an R2 value of 0.99. Additionally, to automate
the quantification of fluorescent microparticles, we developed and trained multiple artificial neural
networks (ANNs) using various training algorithms, and evaluated their performances compared
to the control (ImageJ) and found an R2 value of 0.99. We also performed ANOVA and Tukey’s
post-hoc analysis and found a p-value=0.97 indicating no significant difference.
As a potential application of the designed smartphone-based microscope, we also developed a
PDMS based microfluidic chip to capture and quantify leukocytes from human blood. Anti-human
CD45 antibodies were functionalized inside the capture chamber of the microfluidic chip. These
antibodies captured cells of interest based on antigen antibody interaction. These captured cells
were then made to fluoresce by using a green nuclear stain and the microfluidic chip was imaged
under the smartphone based fluorescent microscope.M.S.Includes bibliographical reference
