Energy efficient smart street light for smart city using sensors and controller
Smart street light is an intelligent control of street lights to optimize the problem of power consumption of the street, late in night. Conventional street lights are being replaced by Light Emitting Diode (LED) street lighting system, which reduces the power consumption. The focus of this project is to design a system of street lights controller to provide a reduction in power consumption. The prototype was designed by using Light Dependent Resistor (LDR), Infrared sensor (IR), battery and LED. The brightness of the lamps is being controlled in this project to reduce the power consumption. The dimming of the lamps depends on the speed of object motion detected such as pedestrians, cyclists and cars. The higher speed of moving object, the greater the level of intensity. For this idea, the innovation of street lights is not quite the same as conventional street lights that are controlled by timer switch or light sensor which automatically turns light on during sunset and off during sunrise. According to the study, motion detection devices may help to save up to 40% of energy per month.

When the LDR detects darkness, it decreases resistance and turns lights on through a relay. When light is detected, resistance increases and lights turn off. The system was tested and installed in offices at a polytechnic to automatically control lighting and conserve electricity. It provides automatic switching without manual operation and reduces energy costs compared to traditional lighting controls.
Best therapy for small superficial treatment areas
The document compares electron therapy and low energy photon therapy for small superficial treatments. Film dosimetry experiments show that electron therapy results in underdosing of the central treatment area and overdosing of surrounding healthy tissue for fields smaller than 3 cm due to the wide penumbra. In contrast, photon therapy provides a more uniform dose across the majority of the treatment area with a much narrower penumbra, avoiding misdosing. Therefore, photons are concluded to provide a safer and more effective option than electrons for small superficial treatments.
Photoelectric calculations
The document discusses the photoelectric effect and calculations related to photon energy. It begins by defining the formula for energy per photon as E=hf, where E is energy, h is Planck's constant, and f is frequency. It then works through examples of calculating the energy of photons with different wavelengths and frequencies incident on various metals. The key points are that photon energy must exceed the work function (W0) of the metal for photoelectric emission to occur, and the kinetic energy of the emitted electrons is equal to the photon energy minus the work function. The document also notes that photon frequency determines the possibility and rate of photoelectric emission from a metal, while intensity affects the emission rate.

The document discusses the photoelectric effect and provides details on several key topics:
1. It outlines 5 main subtopics to be covered in the chapter, including how the intensity and frequency of light affects photoelectrons and the quantitative equations involved.
2. It describes the photoelectric effect as the emission of electrons from a metal surface when light shines on it. Experimental results showed inconsistencies with the wave theory of light.
3. Einstein's photon theory predicted the kinetic energy of ejected electrons would increase linearly with frequency, in agreement with experiments, resolving discrepancies with the wave theory.
Photoelectric effect ppt
This document discusses evidence for both the wave and particle nature of light. For the wave nature, it mentions phenomena like reflection, refraction, diffraction, and interference that were observed in experiments. For the particle nature, it discusses observations that supported Planck's quantization of energy and Einstein's model of light as discrete photon particles, including the photoelectric effect, atomic spectra, and blackbody radiation. The photoelectric effect in particular provided strong evidence that light behaves as a particle by instantaneously ejecting electrons from metals above a threshold frequency, rather than depending on intensity as waves were thought to. This helped establish the dual wave-particle nature of light.
Photoelectric effect ppt
Einstein proposed that light is made up of discrete packets called photons. Each photon has an energy proportional to its frequency. Photons have no mass or charge and travel at the speed of light. The photoelectric effect occurs when photons of sufficient frequency eject electrons from metal surfaces. Experiments showed that the kinetic energy of ejected electrons depends on photon frequency, not intensity. Einstein explained this using a quantum model where photons transfer discrete units of energy. Photoelectric cells and light dependent resistors use this effect, finding applications in cameras, alarms, and other devices.
Opticalcomputing final
The document discusses optical computing technology as an alternative to traditional electronic computing. It notes that optical computing was researched in the 1980s but work tapered off due to materials limitations. Light is well-suited for computing due to its speed, ability to be manipulated, and suitability for parallelization. Optical computing could solve miniaturization problems and allow data to be processed in parallel. Key components discussed include vertical cavity surface emitting lasers, smart pixel technology, wavelength division multiplexing, and spatial light modulators. The document outlines some advantages and challenges of optical computing.

MAGNETIC OPTICAL CURRENT TRANSFORMER
This document discusses magneto optical current transformers (MOCTs). MOCTs use the Faraday effect to measure current optically without breaking the current path. They have several advantages over conventional current transformers, such as providing insulation, withstanding high fault currents without saturation, and having no electromagnetic interference. A MOCT consists of a sensor head near the current carrying conductor that uses polarized light, a signal processing unit, and fiber optic cables connecting them. The sensor measures the rotation of the light's polarization due to the Faraday effect to determine current magnitude. MOCTs are well-suited for outdoor applications and provide more accurate current measurements than conventional transformers.
Optical computers
Optical computers use photons of light rather than electric current to perform computations. They promise massive increases in computer efficiency, speed and decreases in size and cost compared to silicon-based computers. Optical computers use components like lasers, photonic crystals and spatial light modulators to simulate transistors and logical gates using light. Applications include high-speed intercommunication and data processing. Research is ongoing to improve optical switching and signal processing capabilities.
MOCT
The document describes a Magneto Optic Current Transducer (MOCT) which uses the Faraday effect to measure electric current.

Key advantages over conventional transformers include increased safety, simpler insulation, and immunity to electromagnetic interference. While MOCTs provide benefits, their accuracy is currently insufficient for power system applications.

CR & DR..(5).pptx
This document provides an overview of computed radiography (CR) and digital radiography (DR). CR uses an imaging plate that captures x-ray data, which is then processed to produce digital images. DR directly converts x-rays to digital signals using detectors like selenium or scintillator crystals. Both produce digital images but DR has higher image quality and requires less time as there is no imaging plate development step. While DR systems have higher costs, the digital format allows for improved image processing and long-term storage compared to conventional radiography.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
