Induction Heating – Operation, Applications and Case Studies - Presentation S...Leonardo ENERGY
The industrial process heating applications that use electrotechnologies have been found to improve product quality, productivity, energy efficiency, reduce energy intensity and have many other non-energy benefits. Induction technology is another electrotechnology based heating method for heating electrical conductive materials. It involves sending an alternating current (AC) through a copper coil which surrounds the material to be heated or melted. When a metal is placed inside the coil and enters the magnetic field, circulating eddy currents are induced within the metal. The resistance of the metal to the flow of the eddy currents causes the metal to heat up. In this webcast, the operation principles of induction heating technology used for both heating and melting, its applications and EPRI case studies will be presented. The information of vendors as well as other links to reference materials will be presented at the end.
Resistance heating deals with the heating of conducting materials, metallic or non-metallic, in which an electrical current (DC or AC) flows.
In Direct Resistance Heating (DRH) the electrical current flows directly in the con-ducting workpiece to be heated; in Indirect Resistance Heating (IRH) the current flows in special resistance elements, from which the heat is transferred to the work-piece by radiation and convection. Resistace elements and workpiece are situated in a furnace.
Both heating systems must be conveniently designed in order to maximize efficiency and obtaining the desired heating pattern in the workpiece.
In the course the following topics will be dealt with:
• DRH with DC supply
• DRH with AC supply
• Characteristics of DRH bar heating installations
• IRH resistance furnaces
• Materials and design of IRH furnaces
• DRH and IRH heating systems efficiency

Abstract:
High performance and reliable electrical machines
are often required in modern applications and an appropriate
thermal management allows to fulfil such demand. Thermal
management is crucial for improving performance, reducing size
and preserving the insulation lifetime of electrical machines.
From this prospective, a novel cooling method for machine
end-windings is proposed in the present work. Its cooling action
focuses on the end-windings, since they are commonly identified
as the machine hot-spot. The effectiveness of the proposed
cooling method is experimentally proved and the improvement,
in terms of current density, for a given wire insulation thermal
class, is quantified.
A previously designed permanent magnet synchronous
machine, implementing a traditional housing water jacket, is
used as a case study. The influence of the improved current
density on machine torque density is investigated, through finite
element simulations, when the proposed cooling method is
integrated to the existing housing water jacket.
Solar photovoltaic thermal (PV/t) parabolic trough collector systemManav Shah
This system consists of concentrating parabolic trough collector to magnify the solar radiation onto the focal point where absorber tube has been placed. Working fluid such as water is passed from the tube with the help of pump. In order to increase the overall efficiency of the system, photovoltaic cells are placed on the absorber tube so that hot water and electricity can be produced from one integrated system.
Today, multiple manufacturers have products rated at 230°C poised for market release. The tantalum anode, tantalum pentoxide dielectric and manganese dioxide primary cathode material stand up well to these temperatures, although some optimization of the design and manufacturing process for these materials have been required.

A Study on Stochastic Thermal Characterization of Electronic PackagesIJERA Editor
Insofar as the electronics can be found now in several applications of multiple domains, we have tried to
highlight in this study that, those systems must be based on unquestionable reliability and meet the needs of the
external environment. Starting from the unit "°c / w" concerning the thermal resistance from the gap between
junction temperature and a reference temperature, we have tried to compare the thermal performance of
electronic packages taking into consideration the thermal management. Our approach is based on the Monte
Carlo simulation and the stochastic characterization of the QFN. From the norm of normalization, we have
obtained standardized data sheets allowing accurate comparisons of the thermal performance of electronic
packages as produced by different manufacturers. Our numerical model through simulation, prototyping
concerning the design involves the JEDEC recommendations, which we consider a very interesting alternative.
Through the deterministic analysis, we conducted an analysis from the Matlab program parameters, which
control the Ansys software, the results were processed by statistical techniques to evaluate the times of the
thermal resistance of the QFN. That is why we must consider the electronic package (encapsulating the
integrated circuit), through the printed circuit board (PCB) to ensure the junction temperature maintenance and
avoid the dissipation of the heat. Also our process was based on the union of the finite element method to the
Monte Carlo simulation and stochastic characterization of the QFN.

Thermal management of electronics spans the spectrum of handheld devices with no air cooling to rack servers in data centers. Even though methodologies needed for design can be different for each class of electronics cooling problem, proactive engineering at early stage is a common mantra widely accepted in the thermal management community. This presentation will look into the technical and practical challenges associated with implementing a wholistic thermal design approach across a supply chain spanning different companies. With the above as a motivation, the talk will introduce simulation based methodologies for implementing a chip-to-system co-design methodology. Specific topics include abstraction methods pertinent to system, board, Package and Chip. The role of compact modeling, which is an effective tool for communication across domain expertise as well as organizational boundaries will also be discussed. Most importantly, the talk will address the needs of thermal engineers interested in implementing solutions at their organization as well as beneficiaries whose success is vested in cooler, faster and user friendly end products.

The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
