The terms atomic battery, nuclear battery, tritium battery and radioisotope generator are used to describe a device which uses energy from the decay of a radioactive isotope to generate electricity. Like nuclear reactors they generate electricity from atomic energy, but differ in that they do not use a chain reaction.
The purpose of this IEEE 1692 Abstract is to familiarize the reader with the faults that are accountable for most of the
unexplained lightning related damage, and explain the advantages of blocking technologies that can effectively isolate
and protect communications and other equipment.
An e-bomb (electromagnetic bomb) is a weapon that uses an intense electromagnetic field to create a brief pulse of energy that affects electronic circuitry without harming humans or buildings. At low levels, the pulse temporarily disables electronics systems; mid-range levels corrupt computer data.
ARDUINO MICROCONTROLLER BASED UNDERGROUND CABLE FAULT DISTANCE LOCATORIAEME Publication
The growing concern for safety and infrastructural proliferations in the densely
populated urban and suburban areas as well as the quest to preserve the aesthetic
values in many modern localities have necessitated the need for underground
installations. The underground cabling installations are devoid of faults common to the
overhead transmission lines but are associated with certain kinds of faults such as short
circuit and open circuit faults. Locating the exact position of any of these kinds of faults
is very exhausting, costly and time-consuming because its power distribution system is
invisible. Hence, a microcontroller based underground cable fault distance locator
powered by Arduino is designed to detect and pinpoint location of faults in underground
cable lines. A basic ohm’s law is employed to achieve the variation of current with
respect to resistance that determines the position of the fault. This device has a power
supply unit, cable unit, control unit, tripping unit and display unit. The power supply
unit provides power to the other components. The cable unit consists of a three-phase
cabling system with switches between each phase to activate faults. The control unit
takes in signals from the cable unit to cause control of tripping unit and display unit.
The tripping unit then detects the phase which encounters the fault and the display unit
shows the fault characteristics on the LCD. The distance to the fault is displayed,
alongside the phase which encounters the fault for easy clearance.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. Introduction
The most recent war operations relied on air power and precision
guided ammunitions.
Future campaigns will require more suitable weapons to achieve
shock effect over large targets with small attacking forces.
Electromagnetic bombs (E-Bombs) can perform such a role.
6/13/2013 3
4. Basic Principle of E-Bomb
The Electro Magnetic Pulse (EMP) effect .
The Electromagnetic Pulse is an electromagnetic shock wave.
This pulse of energy produces a powerful electromagnetic field
sufficiently strong to produce short lived transient voltages of
thousands of volts on exposed electrical conductors like
wires, printed circuit boards etc.
This can cause irreversible damage to wide range of electrical and
electronic equipments particularly computers and radio or radar
devices.

6. Flux Compression Generators(FCG)
FCG can produce tens of Mega Joules in tens to hundreds of
microseconds.
Main parts of FCG include:
Armature(copper tube).
Stator(helical heavy wire coil).
Initiator(plane wave explosion lens) and

Jacket(prevents disintegration due to magnetic field).
FCG start current is provided by an external source.
When start current peaks initiator is fired to initiate explosive burn.
Explosive pressure expands armature and creates moving short.
Moving armature compressses a magnetic field.

9. Contd…..
Electron beam is accelerated through foil or mesh anode.
Electrons passing through anode will form a bubble of space charge
around anode.
Under proper conditions this space charge will oscillate at micro
frequencies.
Peak power of tens of GW for 100s of sec.
Cheap and simple to manufacture.

12. Firing of E-Bombs:
Warhead comprises of priming current source,FCG(cascade) and
Vircator tube.
Missile installations must supply 100% of weapon priming energy
from own supply.
Bomb installation-weapon can be precharged before release from
aircraft.
A free fall E-Bomb is more lethal.
6/13/2013 12
14. Firing options:
Aircraft Dumb bombs (free fall delivery).
GPS or satellite guided bombs.
standoff missiles.
Cruise Missiles(weight restricted to 340kg).
6/13/2013 14
15. Defence and Hardening
Destroy the delivery vehicle.
Electromagnetically harden/hide important assets.
Use optical fibres for data transfer and comprehensive shielding.
Isolate power feeds with transient arrrestors.
Use non-electromagnetic power feed and electromagnetic “air
lock”.

17. Military applications of E-Bomb:
Electronic combat:
The E-Bomb enables rapid attrition of enemy electronic assets over
large areas.
The E-Bomb offers important force multiplication effects compared
to conventional weapons.
Strategic warfare:
Economic vitals-finance and stock
markets,manufacturing,petroleum are highly vulnerable.
6/13/2013 17
18. Contd…..
Transport infrastructure-signalling and vehicle ignition systems are
vulnerable.
Population-radio and TV receivers.
Military equipments are vulnerable.
Theatre Warfare
Offensive Counter Air operations-disable aircraft in flight,on
ground and destroy their supporting infrastructure.
6/13/2013 18
19. Contd…..
Sea Control-disable surface combatants prior to attack with
conventional weapons.
Punitive Missions:
The E-Bomb is a punitive weapon as it can cause much economic
and military damage with no loss of civilian life.
E-Bombs could be profitably used against countries which sponser
terrorism and info-terrorism.
6/13/2013 19
20. Advantages:
Not lethal to humans.
Negligible collateral damage.
No mass media coverage of bombing casualities(broadcast
equipment destroyed)will reduce threshold for the use of strategic
air power and missile forces.
6/13/2013 20
22. Conclusion:
E-Bombs are weapons of electrical mass destruction.
High payoff in using E-Bombs against fundemental infrastructure
results in substantial paralysis.
Decisive advantage in the conduct of electronic combat.
E-Bombs are non lethal weapon.
The critical issues for next decade are the devolopment of E-
Bombs and hardening of infrastructure.
