The main objectives of the heat transfer analysis is to enhance the heat transfer rate from system to
surrounding. To transfer the heat from any system either by conduction or convection medium. Both modes of
heat transfer has been enhanced by providing an additional equipments in the outer periphery of the heat transfer
system.Fins are basically mechanical structures which are used to cool various structures by the process of
convection. Most part of their design is basically limited by the design of the system. But still certain parameters
and geometry could be modified to better heat transfer. In most of the cases simple fin geometry is preferred such
as rectangular fins and circular fins. Many experimental works has been done to improve the heat release of the
internal combustion engine cylinder and improves fin efficiency.This study presents the results of air flow and
heat transfer in a light weight automobile engine, considering fins with dimple to increase the heat transfer rate.
An analysis has been using ANSYS WORKBENCH version 12.0 was conducted to find the optimum number of
dimples to maximizing the heat transfer across the Automobile engine body. The results indicate that the

It then analyzes 5 cases of converging-divergent nozzles with divergent angles from 15 to 35 degrees. The results show that static pressure decreases and Mach number increases with larger divergent angles, with the optimum angle being 30 degrees where Mach number reaches 3.66.
Class 4 process control loops
This document discusses different types of process control loops. It describes how pressure control loops can vary in speed depending on factors like fluid volume. Flow control loops are generally fast responding but may require filtering to remove noise from flow transmitters. The speed of level control loops depends on vessel size and flow rates. Temperature control loops tend to be slower due to the time needed to change fluid temperature. Various sensors, transmitters, controllers and control elements are used in these different process control loops.

Lecture 22 flapper nozzle & ip converter
This document discusses the nozzle/flapper system and how it can be used for signal conversion between pressure and mechanical motion. It describes how a regulated air supply passes through a nozzle, and the pressure of the signal can be varied based on the distance between the nozzle and flapper. When the flapper is closed, signal pressure rises to the supply pressure, and when open, pressure drops as air leaks through. It notes this system is sensitive in the central region and used in pneumatic controllers. It also explains that current-to-pressure converters use a nozzle/flapper system to linearly translate a 4-20 mA current into a 3-15 psig signal.

2. An experiment was conducted using a heat exchanger with varied inlet temperatures, outlet temperatures, and flow rates as control factors. ANOVA results identified inlet temperature and LMTD as highly influential on heat transfer rate.
3. The optimal parameter combination for maximum heat transfer was determined using S/N ratio analysis.
OPTICAL PYROMETER
An optical pyrometer is a non-contact thermometer that measures the temperature of objects by detecting their electromagnetic radiation. It works by comparing the brightness of the object to a calibrated lamp filament. The observer adjusts the lamp's current until its brightness matches the object, allowing the temperature to be determined. Optical pyrometers are accurate to within +/-5 degrees Celsius and are useful for measuring high temperatures between 1000-5000°F in applications like furnaces or molten materials where direct contact is not possible.
Pneumatic Comparator.pptx
Pneumatic comparators, also called pressure comparators, are precision instruments that use air pressure to compare dimensions. They work by measuring changes in air pressure or velocity caused by differences in the spacing between the measuring surface and workpiece. This allows for high magnification of up to 30,000 times. Pneumatic comparators have few moving parts, are non-contact, and can accurately measure diameters and detect ovality or taper in holes. However, they respond more slowly than other comparator types and require an accurate pressure regulator.

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.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
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.

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.

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.

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.

Editor's Notes
- Helps in Positioning of Spacecraft Helps in detection of Yaw Rate, thus, helps in calculation of steering Error Roll Over detection Gaming Companies use MEMS Gyroscope in making Gaming Consoles Smart Phones are nowadays equipped with it, making it an input device for running of various applications Used as a Image Stabilization device for Cameras and Camcorders Detect Vibrations and Movements, thus robots can work more efficiently
- Gyroscopes are based on the principle of coriolis effect. Coriolis force comes into effect whenever we observe a moving object from a rotating frame. As we can see from the figure. on the right side we see the observer is in the rotating frame and is observing the ball to follow a circular path but when we observe it from the inertial frame we see some other trajectory. The coriolis acceleration is given by following.
- We could see the effect of coriolis force in the nature also. The winds travelling due to pressure differences are deflected due to rotation of the earth. Thermal Gyroscopes are based on the similar principles. Air current is generated by heating. the temperature sensors on both sides would read same values when no deflection is there i.e. when its not rotating. when rotation starts the air deflects on one side thus creating temperature difference. By plotting delta T with omega we can find the value of omega by measuring delta T.
- Stream bend towards the direction of Force, illustrating the Effect of Coriolis Force
- Pressure2 increases with increase in omega while Pressure1 decreases with increase in omega
- COMSOL Calculated Pressure Difference for different values of Omega. Pressure v/s Omega was calculated using Matlab, and curve was fitted linearly to give equation of curve. In the actual device, this Pressure difference can be used to Calculate Omega of the device
- Slope is too high and sensitivity is too low to be of Practical Importance Other devices like Pressure Sensor and pressure creator would be required driving up the cost of device
