A synchronous motor is electrically identical with an alternator or AC generator.
A given alternator ( or synchronous machine) can be used as a motor, when driven electrically.
Some characteristic features of a synchronous motor are as follows:
1. It runs either at synchronous speed or not at all i.e. while running it maintains a constant speed. The only way to change its speed is to vary the supply frequency (because NS=120f/P).
2. It is not inherently self-starting. It has to be run up to synchronous (or near synchronous) speed by some means, before it can be synchronized to the supply.
3. It is capable of being operated under a wide range of power factors, both lagging and leading. Hence, it can be used for power correction purposes, in addition to supplying torque to drive loads.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Impact of Power Electronics on 'Global Warming'.
1. Impact of Power
Electronics on
Global Warming.

2. Abstract
Global energy consumption is increasing rapidly day by day due to increase in world’s population and changes in living standards. Most
of this energy comes from fossil fuels. The burning of these fossil fuels lead to emission of Green House Gases (GHG) causing global
warming. This presentation is the impact of power electronics to reduce the global warming and to utilising the renewable sources.
3. Introduction
● The global energy demand is increasing significantly due to growing population, improvement in the living standard of the humanity, industrialization of
the countries.
● The primary source of energy is fossil fuel.
● Fossil fuel burning causes environmental pollution problems, particularly the Global warming by the emission of green house gases.
● The safe and environment friendly renewable energy sources, such as wind, solar etc are getting more importance in order to decrease the global warming
problems and also expected to replace the conventional energy resources in future.
● Power electronics technique is playing a important role in global energy conservation and helping the environmental pollution control and reduction in
global warming problems.
● About 20% of global energy consumption can be reduced by using power electronics techniques.
● Another 20% can be saved by reducing the losses by using conservation methods.
4. Global Warming Problems
● Adverse effect on world climate.
● Melting of glaciers and polar ice caps.
● In the tropical countries near the equator damages agriculture and vegetation due to drought.
● Arising the cyclone, heavy rainfall and floods. Spread of disease, loss some animal species.
● Sea water acidity increases.
According to UN survey, some of scenarios due to global warming are:
❖ India’s agricultural production will decrease by 38% by 2080 due to absence of water.
❖ 50% of Bangladesh will be underwater in 300 years displacing 75M people.
❖ Within 100 years several Island nations in the Pacific will be underwater.
❖ In Antarctica and Greenland regions melting of ice will cause ocean level rise by 200 ft.
❖ In the world ocean level increases by 210 ft. due to melting of ice.
❖ Arctic regions will becomes free of ice by 2070.
❖ If today fossil fuel burning is completely stopped, ocean level will rise by 4.6 ft. in next 1000 years.
5. IMPACT OF POWER ELECTRONICS
Power electronics helps to improve the energy efficiency and generation of environmental friendly energy or green energy.
In addition to applications in energy systems and industrial automation, power electronics is now playing a significant role in global energy conservation that is
helping environmental pollution control indirectly, i.e. solving the global warming problem.
Some of them are,
1. Solar Energy
2. Wind Energy
3. Lighting
4. Electric/Hybrid Vehicles
6. Solar Energy The process of converting solar energy into electrical energy by use of solar
cells called the photovoltaic effect. The efficiency of a solar cell is depends by
its ability to convert available sunlight into usable electrical energy. Solar cells
must have large surface areas so as to produce large amount of power. The
main role of power electronic interfaces for the PV systems is to convert the
generated DC voltage into a suitable AC for utility connection and consumer
use. The generated DC voltage magnitude is required to be boost to a higher
value by using DC-DC converters (chopper) before converting them to the
utility AC. The DC-AC inverters are then used to convert the voltage to
required frequency AC.
7. Wind Energy Wind energy is source of clean energy. Wind turbine system converts the
kinetic energy of the wind into mechanical energy that can be converted into
electrical energy with a generator.
The important features considerations with wind energy conversion system are:
❖ Available wind energy.
❖ Type of wind turbine employed.
❖ Type of electric generator.
❖ Power electronic circuitry used for interfacing with the grid.
8. Lighting Power electronics based high frequency compact fluorescent lamps (CFLs) are
much more i.e. four times more efficient than traditional incandescent lamps
and giving longer life. Light dimming control method of CFL can further
improve energy efficiency. In the future the CFLs are completely replacing the
incandescent lamps. The Solid state LED lamps with higher efficiency and
longer life compare to both incandescent lamps and CFLs.
9. Electric/Hybrid Vehicles In Electric Vehicles (EVs) battery is the very important component because it
stores energy. The dc is converted to variable frequency variable voltage ac
with the help of power electronics to run the propulsion motor (induction or
synchronous motor). During braking energy can be regenerated and restore in
battery. The range in EV is limited by battery capacity, but in Hybrid Electric
Vehicles (HEVs), there is no such problem. Unfortunately, battery technology
today is not yet mature. It is bulky, expensive, has limited life cycle and long
charging time. The Ni-MH batteries have been used extensively, currently
because it has large storage density, but expensive. There is large emphasis on
Li-ion battery research in recent years. Presently Most of EVs/HEVs uses
Li-ion batteries
10. CONCLUSIONS
➢ Global energy demand is increasing continuously,
major part of these energy demands are fulfilled by the
non-renewable energy sources like coal, natural gas, oil
etc.
➢ These energy sources may last for another 200 years.
Also generation of power by these sources leads the
emission of green house gases which increases the
earth’s temperature and causes global warming.
➢ Renewable energy sources (solar and wind) play
important role as energy sources in future. Power
electronics technology will play very important role in
energy saving.
➢ Green and Clean energy generation is made possible
using power electronics and reduction in green house
gas emissions, hence reduction in global warming.
