THE GREAT THOMAS ALVA EDISON

Let me say about EDISON in detailed,he studied for 3 months duration.and he is having very much zeal on experiments,at age of 8 years he setup his own laboratory at home.the requirements can buy it from MARKET by working as child labor.so he is not a rich man at starting.and keep on doing experiments at home ,and his mother was scared about him “one day the house was fired with his fault experiment “once up on a day he travels in train,and doing some experiment due to that the compartment fired than police was arrested him.and he was in jail for 6 months.

Finally THOMAS ALVA EDISON invented a bulb not only bulb, and he invented 1 ,2,3 ……………1093 new devices.

So friend try try try ………until and unless you get a success.

Odisha School Girl Wins Award At Google Science Fair For Developing Water Purifying Agent

Lalita Prasida Sripada Srisai, a 13-year-old student of class 9th in DPS Damanjodi in Koraputdistrict of Odisha, has made India proud by winning the ‘Community Impact Award’ at the prestigious Google Science Fair in California on Tuesday. Winning the award in the 13-15 years age group, she received 10, 000 USD as the prize MONEY She is also set to be supported by Google for a year to build her project.

Lalita developed a low cost bio-absorbent based water purifier. It functions mainly on waste corn cobs. The Corn cob is the least utilized part of the maize plant. It is a very important agricultural waste. Having high mechanical strength, rigidity and porosity, corn cob is a suitable absorbent. This enables contaminants like oxides of salts, detergent, suspended particles, coloured dyes,oil and grease to be absorbed in the surface of the corn cobs. Some of the heavy metals are also absorbed.

“If the drain pipe of the household is connected to a chamber having different layers of corn cobs in partition layers or to an S-trap pipe having corn cobs, it will separate about more than 70-80 % of contaminants including suspended particles from the waste water,” says the report published about her project on the Google Science Fair website.

This cheap and eco-friendly way of purifying water will open up a new market for corn corbs which are otherwise discarded as bio-waste.
To conduct the experiment, Lalita had collected the cobs from a nearby farm and sun dried them for a month. To make a hole at the centre of one cob, the pith was removed. In it 50 ml of domestic effluent collected from a kitchen drain pipe was poured. This was allowed to pass through the hole. Thereafter, the collected filtrate was tested for purity. This was the pilot stage.

After its successful completion, water with several added chemical impurities was through five bottles, each containing a different layer for purification. The layers had long pieces of corn cobs, small pieces of corn cobs, powdered corn cobs, activated charcoal made from corn cobs and fine sand.

The charcoal layer was observed to absorb most of the coloured substances present in the water, while the chaff layers of both long and small pieces of corn cobs absorbed the suspended particles. The powdered corn cob layer absorbed the gasoline waste.

Lalita’s teacher, Pallabi Mahapatro, claims that the technique can be used for immobilizing the contaminants in domestic and industrial effluents, and in ponds, reservoirs and water tanks.

For the time being, Lalita’s peers and staff at her school have been celebrating this grand victory while many are congratulating her on social media.

The Principal of DPS Damanjodi, Trinath Prasad Padhi, reveals that Lalita is also very proficient in co-curricular activities like song and dance. She is set to receive a grand welcome on her return to school through a major function.

see how power full positive belief was???

The importance of positive thinking (positive belief)Friends!

up to 1966 the whole world, says and trusted that “it was impossible to run  1 mile distance in 4 minutes for human. And medical doctors says its due to bleed circulation can’t be withstand for that level like that”

One day the great fellow and athlete named as “ROJER BANNISTER” practiced so many times, and chases the mile distance within 4 minutes. On that day his name announced in TV’s, newspapers and radios as well.

After that 30 peoples chase the same task within 4 minutes by his inspiration.

Today any athletic can run 1 mile distance within 4 minutes.

So friends in our body contains lot of energy. More than our assumption.so belief positively.

see how dangerous negative belief was?????

The drawbacks of negative thinking (negative belief)Friends!

మన మెదడు ఎంత విఛిత్రమినదంటే ????? అది మనము ఏమనుకుంటామో దానిని నిజం చేయడానికి ప్రయత్నం చేస్తాయి.

Why because human brain contains 10% power for conscious mind and remaining 90% for subconscious mind.

Because that reason the scientists and writers gets thoughts at night at most of times.

But we are not supposed to use subconscious brain well.and we are using that brain for stupid thoughts at night.

Ok fine wat am mentioned at top “మన మెదడు మనమనుకున్న వాతిని నిజం చేస్తుంది అని”,చుద్దాం ఎలానొ

ఓక రోజు నేను చదువుకుంతుంతే మా అమ్మ పిండి రుబ్బుకుంటూ నాకొక పని చెప్పింది,ఒరేయ్ నాకు ఉప్పు 

డబ్బా తెచ్చిపెట్టు అని చెప్పింది,అప్పుదు నేనన్నాను, నీ వంట గది ఒక గందర గోలము,బంజల దొడ్డి,దాంట్లొ 

నాకేమీ దొరకదు నువ్వే వెల్లి తెచ్చుకో అని.దానికి మా అమ్మ అన్నది,రెయ్ నేను వెల్లాలి అంతె చేతులు కదగాలి 

నువ్వు వెల్లు దొరుకుతుందిలే అని,అయిస్టం గానె reluctantly I went to the kitchen and search for salt 

bottle for 20 min in wean.ఆది నాకు దొరకలా వెంటనె మా అమ్మ దగ్గరకు వెల్లి నేను అప్పుదే చెప్పా నీ వంట గది

 ఒక గందర గోలము,బంజల దొడ్డి,దాంట్లొ నాకేమీ దొరకదు అనీ నువ్వు వినలేదు,ఇప్పుదు చూది నీ టైం వేస్ట్  

అయ్యింది న న టైం వేస్ట్  అయ్యింది.అప్పుదు మా అమ్మ చేతులు కదుక్కొని న బుజం పట్టుకొని నన్ను కిత్చెన్ 

లోకి తేసుకు వెల్లి,she showed me where the salt bottle was, to my shocked and surprised, the salt bottle 

lie in kitchen at middle of dining table. I may have looked that it but may could not seed.

నేను దానిని చూసే ఉంటాను ,కానీ నాకు అది కనపదలేదు.

నేను దానిని చూసే ఉంటాను ,కానీ నాకు అది కనపదలేదు   ఎందుకూ?????????? నేను గట్టిగా నమ్మాను అది నాకు 

కనపదదూ …… అని,   నా మెదడు ఏమి చేసింది,న ఆలొచనను నిజం చేసింది.చుసారా friends how dangerous negative thinking was?

So friends don’t think negatively and think positive than you can carry your subconscious mind power with you.

Success is not like a instant coffee. Most of the successes start with failures ex.FOURIER

3.FOURIER  & FOURIER SERIES

>> As a historical note Fourier is a French mathematician com administrator.in French his name pronounced “Fourier”, in English his name Fourier.

>> According to Fourier any type of periodic signals can be expressed with dc component + sum of different sinusoidal waves.

fig.1

                                                                         Fig.2

Generally square wave=fundamental sin wave (H1)+H2+H3+--------+Hn      see in fig.1

But we need to truncate series for easy calculations

Square wave=H1+H2+---+H49         see in fig.2

>>it gave raise to some sort of controversy.

>>based on his work Fourier submitted a paper .but apparently it could not be accepted in a scientific journal, because very eminent mathematician who was the referee seriously objected it

                                                Start with failure

>>in this event Fourier finally published in the form of book.

>>now a days Fourier forms plays a vital role in engineering & science, and is still going to increase their demand in science&engineering.

Success is not like a instant coffee

Success is not like a instant coffee. Most of the successes start with failures

From today onwards I will give examples of successful persons start with failures

Ex:1,2  henry Ford(inventor of FORD CAR) &Thomas Alva Edison (inventor of BULB+1092 things)

Henry ford studied up to 6^th class.but he is invented automobile (car).his spread the cars for every American at cheap cost.

And secondly Edison was great man invented 1093 new things. See how great he is?

He is discovered not only 1 or 2 or 3,its 1093 things. Butwe are knowing his name popular for inventor of ELECTRICAL BULB.

Do u know that “Edison studied only 3 months ,not even a year also.its true and not a joke.

>Now the question is “How the 6^thclass Ford can discover a CAR,and how the Edison(3 months study duration) can discover a 1093 things???????”

Ans:these two peoples HENRY FORD,THOMAS ALVA EDISON has a common friend  named as “napoleon hill”.

he was the friend &psysicien& teacher.and he motivate those peoples towards success and insert one type of positive mental attitude to those fellows.each and every cell of the body can filled with that attitude,that’s why EDISON invented a bulb and FORD invented a car.

But friends those are not succeed by single try.

Let me say about EDISON in detailed,he studied for 3 months duration.and his having very much zeal on experiments,at age of 8 years he setup his own laboratory at home.the requirements can buy it from market by doing as child labor.so he not a rich man at starting.and keep on doing experiments at home ,and his mother was scared about him “one day the house was fired with his fault experiment “once up on a day he travels in train,and doing some experiment due to that the compartment fired than police was arrested him.and he was in jail for 6 months.

Finally THOMAS ALVA EDISON invented a bulb not only bulb, and he invented  1 ,2,3   ……………1093 new things.

So friend try try try ………until and unless you get a success.

advance happy birth day to Nobel prized scientists.those are placing a ladders to us to growing our knowledge and helps to further research

SCADA (supervisory control and data acquisition)

SCADA (supervisory control and data acquisition) is a type of industrial control system (ICS). Industrial control systems are computer-controlled systems that monitor and control industrial processes that exist in the physical world. SCADA systems historically distinguish themselves from other ICS systems by being large-scale processes that can include multiple sites, and large distances.^[1] These processes include industrial, infrastructure, and facility-based processes, as described below:

• Industrial processes include those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes.
• Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, wind farms, civil defense siren systems, and large communication systems.
• Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations. They monitor and control heating, ventilation, and air conditioning systems (HVAC), access, and energy consumption.

A SCADA system usually consists of the following subsystems:

• Remote terminal units (RTUs) connect to sensors in the process and convert sensor signals to digital data. They have telemetry hardware capable of sending digital data to the supervisory system, as well as receiving digital commands from the supervisory system. RTUs often have embedded control capabilities such as ladder logic in order to accomplish boolean logic operations.
• Programmable logic controller (PLCs) connect to sensors in the process and converting sensor signals to digital data. PLCs have more sophisticated embedded control capabilities, typically one or more IEC 61131-3 programming languages, than RTUs. PLCs do not have telemetry hardware, although this functionality is typically installed alongside them. PLCs are sometimes used in place of RTUs as field devices because they are more economical, versatile, flexible, and configurable.
• A telemetry system is typically used to connect PLCs and RTUs with control centers, data warehouses, and the enterprise. Examples of wired telemetry media used in SCADA systems include leased telephone lines and WAN circuits. Examples of wireless telemetry media used in SCADA systems include satellite (VSAT), licensed and unlicensed radio, cellular and microwave.
• A data acquisition server is a software service which uses industrial protocols to connect software services, via telemetry, with field devices such as RTUs and PLCs. It allows clients to access data from these field devices using standard protocols.
• A human–machine interface or HMI is the apparatus or device which presents processed data to a human operator, and through this, the human operator monitors and interacts with the process. The HMI is a client that requests data from a data acquisition server.
• A Historian is a software service which accumulates time-stamped data, boolean events, and boolean alarms in a database which can be queried or used to populate graphic trends in the HMI. The historian is a client that requests data from a data acquisition server.

• SCADA is used as a safety tool as in lock-out tag-out
• A supervisory (computer) system, gathering (acquiring) data on the process and sending commands (control) to the process.
• Communication infrastructure connecting the supervisory system to the remote terminal units.
• Various process and analytical instrumentation

principle of engineers

We are electrical engineers but wat we know just compleeted b.tech with distinction still waiting for job. Thats not an engineering i think. we are just study abt conventional (old and basic) machins in our syllabus. but in this world at present so many special machins is avialable. but we dont know even though we are planned for further studies like pg. Finally wat am told that machins gurunchi sariga avagahana lekunda vatini ela design or controlling cheyagalam. "if we dont know diseases how can we apply drug to cure that. Andhuke antaru appude mbbs compleet chesina doctor kante well experienced compounder better ani. I.e the technology still running in this world but we are not runnig with them just one are two peoples are running . We are just seeing them.anduke steady state characteristics kante dynamic characteristics ku value is high. so try to run with technology.

If you checked abt top 100 sciencetists means most of legends from germany and united states and united kingdom why cont we become to chase them good followers are having more chances to reach those stars so wat we become to do nothing to get seat at top universitys and nothing to got top marks in courses also but wat ever you selecting subject just love it like it dream it
you must remember there is no subject is wast in world and the peoples got ranks by how much they learn on that subject and how much they know the same
