Ideas for a speedy,effective and cost efficient education


Hi make the following post , these are my ideas , i want them to be implemented.

1)All offices and homes must be attached or must be at a walkable distance i.e., No transport must be required to go for office to home or home to office.Cities must be planned as such.

2)All colleges must have compulsory hostels and special permission must be given to depressed/home sick students who wish to live with family.The two above points will save tons of petrol from being consumed and will have a positive effect on Indian economy.

3)Websites like flipkart.com must be given more support technically and must rapidly expand , all online shopping websites must be integrated.All small & medium shops in CITIES must be integrated into the online websites compulsorily.The government must supply a small basic TABLET computer which help people who don't have money to buy daily items from these shopping websites.Those people who lose their jobs after the shops are closed will be given free training material(pdf files)  which can be read on their tablet computers provided.After a period of 6 months those all who have lost their jobs MUST write a test and get NEW JOBS.THE TRAINING AND JOBS WILL BE TECHNICAL EITHER MEDICINE RELATED OR ENGINEERING RELATED.The following shops must be closed:shops selling all kinds of Textiles shops selling all kinds of Electronic itemsshops selling all kinds of Shoes and accessories,Vegetable and non-veg selling shops and markets selling grocery items etc.Toy shops ,Shops selling baby products.Servicing shops for all electronic items.Real Estate Agencies, Jewellery shops And all of these online must allow COD-CASH ON DELIVERY , To prevent Prankers from ordering items to somebody else's address , a verification system is required -a 5 digit code will be sent to the customers mobile phone for confirmation of a set of purchases,which has to be entered in the webpage to confirm deal.A genuine reason must be for cancellation,If somebody plays a prank for more than 5 times , the person must pay a fine.Those who lose their employment in this process(from shops closing) and are unable to pass the tests(held by government for technical employment) must be made to transport goods from/to customer place to/from warehouse where these materials are sold.In case these people are still interested in studying they must be allowed to write a re-test after 6 months and will have to pay a small fee.There are many other jobs like Chef,house keeping,security guards etc for people unable to travel to deliver products due to age/handicap.For those who don't are interested in learning full time and want to pass these exams faster and are aiming for BETTER JOBS such as in D.R.D.O. etc must be given notes(pdf files) from IIT free of cost in a special reading hall where the person can study the notes,the person must not be allowed to take the computer on which he reads the notes provided out of this reading hall,no other electronic items must be allowed into this reading hall.This kind of reading hall must be available in every major city and town and village.The reading hall will have only fans and tube lights and 1 chair for each person.A small fee is taken from the readers for maintenance.a separate tablet computer for this reading hall users will be provided by the Government.this reading hall must be open 24 hours a day , 7 days a week, 365 days a year. The only people managing the reading hall will be highly trained security guards , a manual will be displayed in different languages for people who don't know how to use a tablet computer. Proper Hygiene in the Reading room must be maintained by the security guards.No canteen in the building housing the reading room . Only rest rooms will be present in one corner of the building housing the reading room on each floor.In tamil nadu,Laptops have been given to all college students but very few of the recipients of the laptop i know use it to listen to music and play games,watch movies !
My solution:Interactive software which  is based on psychometric analysis and mutates depending on the student to make the student more interested in learning is essential,otherwise building libraries and distributing laptops is of little use !To prevent terrorists from entering this building,Voter's ID card,Passport or a smart card issued by the library have to be produced everytime users enter the library.


If the Government does not undertake the task,then a private concern may follow the following steps to achieve:
Phase 1:Online shopping website.
Must include every single shop in the remotest part of the city,If a person in xyz street orders a packet of Lays online ,a message is forwarded to the shop in that street,that person sends the product to the customer.
The business firm has the option of providing & maintaining a delivery boy to the shop-keeper.
The customer can be pulled towards buying products by giving them Gifts when they purchased above Rs.10,000 in a stipulated period of "X" months,The gift can be a educational book,software,hardware,stationery item,music CDs etc
The business man can also tie up with major book manufacturers to provide CDs/books worth Rs.1000+ as free gifts possible when large number of people are eligible for the price.

Phase 2:
Every person directly connected as a staff to this online website , will get study material in the form of pdf (if interested).For future studies.

Phase 3:
Re-arrangement of city.

Post dedicated to the Government of India & Tamil Nadu:

Reg: Better transportation  better safety for passengers of MTC bus.
The MTC buses must have Google's self - driving car software installed in them , 
with manual intervention which could be useful in case of failure.

A MTC bus commuter who is very sure will use MTC bus service for more than 100 days in a period of 4  months 
should be granted a bus pass before the period of 4 months or after the period of 4 months on submitting proof.
The passenger will be able able to get a refund of atleast Rs.200(If the route is longer ,more savings are possible).

Proof required to be submitted by passenger for refund of extra money:
The passenger can either submit tickets or MTC can implement the following technology which must be combined 
with the technology used by google in self driving car.

A device similar to a mobile phone must be provided in combination with the following technology:

An effective alternative to this is the system used by Apollo hospitals to track patients:
A sticker with a bar code is applied to the arm of the patients which is used for identification,similarly a complex bar code 
can be attached to the ID card/bus pass which also has photo graph of the person for whom the bus pass has been provided by MTC, 
so that the MTC BUS CONDUCTOR can simply scan the bar code and give a ticket or a duplicate bus pass if the person
is robbed of the original bus pass.

Also a mobile phone app can be introduced which will ease the commuter on the time remaining for a MTC bus 
to reach a particular bus stop.
The mobile app must provide the following details:
1)The MTC bus number that arrive at a particular bus stop in tamil nadu.
2)the time a MTC bus will take to arrive at a particular bus stop in tamil nadu.
3)The time a MTC bus with empty seats will arrive at a particular bus stop.
4)The *minimum* time taken by a MTC bus to reach a particular bus stop.With the help of (Google self driving)GPS, the *approximate* maximum time a bus will take to arrive
at a bus stop can also be calculated.Google's elf driving can calculate approximate time based on the speed of the vehicle even if it is manually controlled.
5)The app must be secure against hackers and free mobile anti-virus must be suggested to be downloaded,installed and scanned before this app is downloaded.
6)the app must be made available for different platforms , this can be done by introducing a multi-platform app or the A version of the same app for various platforms ranging from Android ,Ubuntu to Windows Phone.

In Addition to mobile phone app the following must be implemented on every MTC bus stop in chennai :
1)A large Led display displaying the following details must be made available:



THE WORDS 
 COLUMN 1 IS TO BE REPLACED BY "BUS NUMBERS"
 COLUMN 2 IS TO BE REPLACED BY "TIME LEFT FOR THE NEXT MTC BUS TO ARRIVE AT THIS MTC BUS STOP"
 COLUMN 3 IS TO BE REPLACED BY "NUMBER OF BUSSES OF THE NUMBER MENTIONED IN COLUMN 1 WILL BE ARRIVING IN THE TIME MENTIONED IN COLUMN 2"

    THE ALPHABETS IN DARK PINK FONT IN THE ABOVE PARAGH ARE TO BE REPLACED BY THE ALPHABETS IN GREEN FONT IN THE PLACE OF DARK PINK FONT IN THE LINE BELOW.

  Column 1     ||||||||||  Column 2      |||||||      Column 3

           27D                   30 MINUTES                         1
           23C                  30 MINUTES                         2
           120                   15 MINUTES                         3
          


ADVANTAGES OF GOOGLE'S SELF DRIVING TECHNOLOGY WITH RESPECT TO MTC.
1)The technology will calculate the most fuel-efficient and fastest route from source to the destination, agreed that MTC buses
follow the same route every day,but their speed is not the same, Google's technology can vary the speed of the MTC bus 
to achieve fuel efficiency,speed of transportation,safety of passengers in extreme cases.
2)In case an ambulance is on it's way to a hospital,The speed of the MTC buses on their respective routes will be adjusted such
that the Ambulance is at it's fastest.
3)In case of an emergency within the MTC bus , the MTC bus can commute to the location where the critical nature of the emergency is at it's minimum.
4)Further development can be done to google's self driving technology by adding a method to detect the engine conditionas to detect any malfunction
due to which it may break down,so that the bus will be guided to the next bus stop while another bus is directed to the particular bus stop to commute passengers.
The MTC bus which is about to break down is safely guided to it's garage or to the side of the road.
5)Google's technology can be further improved by the following idea
(suggestion must be sent to google by the state government ,So that Google launches
such technology ASAP).
Keeping the engine of the MTC bus in working condition when it is about to be damaged 
and reverse the process of damage to the vehicle by using certain chemical solutions which can be stored in the vehicle
and can be let to the desired part of the engine to control the damage to the vehicle.


If the bar code cannot be used by the MTC,then MTC must provide a device like a basic mobile phone worth less than Rs.1000 INR having an IMEI number which can be tracked and retrieved on being robbed/lost.
The device must be capable of sending messages , making calls and must have a pre-installed app with the features of the app mentioned above.The firmware of this device must be very secure.


BENEFITS OF MAKING THE ABOVE IDEA A REALITY :
MAJORITY OF THE NON-TECH PUBLIC WHO DO NOT CARRY VALUABLE ITEMS DURING THEIR DAILY JOURNEYS WITHIN CITY LIMITS WILL SHIFT TO
MTC BUSES.ALSO IT WOULD BE VERY HELPFUL IF A POLL IS AVAILABLE WITH THE FOLLOWING QUESTIONS AND MORE:
1)WOULD YOU PREFER TO TRAVEL IN AN MTC BUS WITH AIRCONDITIONER IF IT IS AFFORDABLE ?
A)YES       B)NO
2)CAN YOU AFFORD TO PAY THE TICKET WHICH AMOUNTS TO Rs.INR FOR AC BUS ?
A)YES       B)NO

I GOT THE IDEA FROM THIS WEBPAGE

MY PERSONAL SUGGESTION:Introduction of Complimentary Tablet/Cell phone battery charging in AC BUSES,FIRST CLASS LOCAL TRAIN COMPARTMENTS .
THE CABLE OF THE CHARGER MUST BE AVAILABLE WITH THE CONDUCTOR AND BE PROVIDED ON DEMAND,ONCE INSERTED INTO THE CHARGING SOCKET
IT MUST BE REMOVED ONLY USING A SPECIAL KEY WHICH IS PROVIDED TO THE CONDUCTOR.
ALSO YOU COULD PROVIDE DOWNLOADS OF EDUCATIONAL & BUSINESS MATERIALS SUCH AS FREE & COMMERCIAL MAGAZINES/BOOKS,MUSIC , MOVIE CLIPS, GAMES WHICH ARE STORED ON A EXTERNAL DRIVE AND CAN BE
TRANSFERRED USING A UNI-DIRECTIONAL DATA CABLE/BLUETOOTH.ALSO A DIGITAL TELEPHONE DIRECTORY CAN BE PROVIDED TO SMART PHONE/TABLET/LAPTOP USERS TO ACCESS CONTACT INFORMATION OF
CARPENTERS,PLUMBERS,WELDERS,CEMENT SUPPLIERS,FURNITURE SERVICE & RETAIL/WHOLESALE,SHOPPING PLACES IN CHENNAI , LIST OF GOVERNMENT/PRIVATE TOURIST PROVIDERS,HOSPITALS FOR POOR AND HOSPITALS 
FOR RICH,WITH REGULARLY UPDATED CONSULTATION TIMES OF DOCTORS,LABS,LIST OF COMPUTER TECHNICIANS,AUTOMOBILE MECHANICS,COURIER SERVICES,
FIRST AID FOR PATIENTS REQUIRING EMERGENCY ASSISTANCE comprising of INJECTIONS,TABLETS ,BASIC MEDICAL DEVICES.
ALSO A MOBILE BASED GROCERY SERVICE CAN BE PROVIDED BY IRCTC/MTC, WHERE YOU CAN ORDER BY CONNECTING TO IRCTC/MTC SERVER VIA BLUETOOTH ON TABLET/LAPTOP/MOBILE PHONE
OR BY VISITING THE WEBSITE OF IRCTC/MTC AND THE ORDERED PRODUCTS WILL BE DIRECTLY DELIVERED TO THE COMMUTER WHO HAS ORDERED 
AT THE SPECIFIC TIME FOR AN EXTRA COST.
ALSO BASED ON THE REQUEST OF REGULAR MTC BUS COMMUTERS, AND ON PAYMENT OF A DEPOSIT,THE MTC MUST AGREE TO FETCH ACCESSORIES OF COMPUTERS,ELECTRONIC ITEMS,
OR BETTER THE MTC MUST SIGN AN AGREE WITH WWW.FLIPKART.COM AND SIMILAR WEBSITES.

Also,Airconditioning might be helpful,But costly,A Cost-effective alternative is as follows.
"

 If the speed of commutation is increased along with fuel, The passenger will be exposed to lesser pollution because on the whole all the vehicles are moving on a 100 % pre-(better)planned route using the idea mentioned above.
 "
Last but not the least, a bus conductor informed me that MTC bus co-operation is being sold off to a private organisation and will not be a Government service anymore,In case if it is due to the Government Lacking ideas , then the above has plenty,If the Government must sell MTC i suggest it sells MTC to Google ,Obviously after forcing Google to open it's Wholly owned Indian companies (WOIC) in India , for more details Please open the following link http://rahulmehta.com/301.pdf and search for the folowing phrase: "WOIC".

An UPDATE AWAY FROM THE MAIN TOPIC (contribution to https://www.khanacademy.org/)



The main problem is not collecting and creating the information , It is maintaining the security of the website,keeping the website online at all times,Because such one website can cause the downfall of many others.

My humble suggestion would be that The Many websites present on the internet must collaborate & co-operate with each other and Form a SINGLE WEBSITE ,Based on the links a user clicks , the person who suggested & secures the links be put on the web page gets the money.

There are better websites,My humble suggestion , kindly merge with them.If you want to educate,If you want to earn Money carry own ...ALL THE BEST.


Many of the status contain queries on the following topics included in the list below:

I very humbly request the admin of this group to include the following in the *pinned* post and it's comments.

The most important:(NEED GUIDANCE -GET IT FROM THE BEST-FOR UG LEVEL ONLY,I DON'T KNOW ABOUT PG & HIGHER)
Google search :forbes.com best universities world wide

This webpage appears:
http://www.forbes.com/sites/susanadams/2012/10/03/the-worlds-top-universities-2012/

search for names of universities found in the links in the  webpage 

Next open google search in a new tab:
type the following in the search box or you can use advanced search option:

site: ft:

example:

site:caltech.edu homerf ft:.pdf ft:.ppt ft:.doc

If the above does not work try something like this:

This is lengthier but more effective

This is the search phrase (Precautions need to be followed in this method,skip few lines to know them)

site:*.edu homerf


'*' indicates all characters in a string of every possible length.




Some websites end with .org hence if you don't get the search results using the above phrase try:
site:*.org homerf
Google has certain bugs due to which i am not getting perfect results while i combine two different domain names,Bug seems to hide universities even using advanced search.


Precautions to be followed in the second method:
Verify a url that appears in the search before clicking it using 

who.is
www.siteadvisor.com
http://www.domaintools.com/

After you find out the owner/organisation name , Google the owner/organisation name to find out whether such a university exists,If it Does ,You have got very good tutorial for the topic you have been searching !

How can this be Improved ?
A firefox add-on ,Chrome extension helping us verify the websites or a google feature which lists only webpages of Universities/colleges.


Last request DON'T USE INTERNET EXPLORER ! Chrome and Firefox are faster(And more secure according to online statistics)

Directed Energy Weapon - CHEMICAL LASER GUN & Active Denial System for the Local POLICE



Recently:
foxnews.com
http://www.foxnews.com/story/0,2933,518142,00.html

says that government has tested the LASER and termed it as useless since it produces no pain , but this could be used as a warning system before the active Denial  System is out to use .
An advanced version of this is used in the Air Force to attack missiles and prevent the missiles from causing damage to allied forces.

LASER - Light Amplification by Stimulated Emission of Radiation , its main characteristic dense collimated beam can be used for defense right from the aerospace to the local police with lathi depending on the intensity of the beam.

This article, for the local police could carry a non- lethal LASER GUN which would blind you only for the moment been rather than permanent damage and injury to internal organs . It's specification:

Specifications:
500 Milliwatt, 532nm (Green) Flashing Laser
Overall Length 11 Inches, Maximum Diameter 2.25 Inches
Powered by Primary Lithium Batteries
Delivery: 8 weeks ARO

source:laserdazzlers.net (go to GOOGLE - TYPE "laser dazzlers" click on most appropriate link.
For more General details visit above mentioned site.


Since the CHP Laser DazzlerTM (Patent Pending) is designed to
be compact yet effective at distance in bright ambient
conditions IT IS NOT SUITABLE FOR CLOSE IN WORK DUE TO
ENERGY DENSITIES THAT HAVE THE POTENTIAL OF CAUSING
IRREVERSIBLE EYE DAMAGE AT CLOSE RANGE.

To prevent the above what changes could be made , the intensity of the LASER BEAM could be decreased by varying the power

armlaser.net
Designed with a tempered black pure hard aluminum casing, the Armlaser 300mw green laser dazzler can withstand extreme laser functionalities, may it be in the battle field or inside a laboratory. extremely effective, non-lethal, waterproof high powered green laser built specifically for rugged, harsh environments. This laser is classified as TALI™ (Threat Assessment Laser Illuminator)          



Another product has been featured on Discovery Channel's "Future Weapons",  is equipped with versatile focus-adjustable collimating lenses to compensate for range and power intensityi'd seriously consider red diode based lasers. Most green laser assemblies will not be able to tolerate the shock/recoil for very long , will cause the material to get plasticized and result in damage.
But doing this would result in the confusion of the laser be termed as class 3 B or class 1 , due to it's varying damage on the eye referencecd to MPE- Maximum Permissible Exposure.


for information on safety of lasers: 


The following device is not only more effective in dispersing people but will not result in severe Injury caused by Lathis PROVIDED THE INTENSITY OF THE RADIATION EMITTED FROM THE ACTIVE DENIAL SYSTEM IS BELOW THE THRESHOLD WHICH CAN BE SERIOUSLY INJURIOUS TO HUMAN TISSUE.
This primarily a replacement for the lathis used by the local police One laser mounted on a vehicle would be sufficient to deal a crowd instead of many lathis and many police officers being involved and getting themself injured.



If the frequency of the emitted spectrum is moved away from what is being used in the laser dazzler then the active denial system which operates at higher frequency is got.
The intensity of the device can be changed to cause intense pain or to kill the person or crowd.but the power involvement is very high , i am very much in favor of the above technologies because a single weapon can tackle a large crowd , very useful if a stampede occurs and if they are mounted at appropriate position at traffic signals then one of them could be used on a traffic rule breaker depending on the harm caused/causable due to violation of the law.



The difference is that the active denial system requires more power , more tough material and is more dangerous(IF NOT HANDLED WITH PRECAUTIONS), BUT effective.

Drift Tolerant Phase Shift Memory

PCM leverages the resistance change that occurs in the material -- an alloy of various elements -- when it changes its phase from crystalline (low resistance) – to amorphous – featuring high resistance – to store data bits. In a PCM cell, where a phase-change material is deposited between a top and a bottom electrode, phase change can controllably be induced by applying voltage or current pulses of different strengths. These heat up the material and when distinct temperature thresholds are reached cause the material to change from crystalline to amorphous or vice versa.

In addition, depending on the voltage, more or less material between the electrodes will undergo a phase change, which directly affects the cell's resistance. Scientists exploit that aspect use four distinct resistance levels to store the bit combinations "00", "01" 10" and "11".

The scientists implemented an iterative "write" process to overcome deviations in the resistance due to inherent variability in the memory cells and the phase-change materials:

We apply a voltage pulse based on the deviation from the desired level , measure the resistance. If achieved, we apply another voltage pulse and measure again – until we achieve the exact level.

Worst case Performance:10us 100 times slower than flash memory to get the desired resistance.

For demonstrating reliable read-out of data bits,  tackling the problem of resistance drift. Because of structural relaxation of the atoms in the amorphous state, the resistance increases over time after the phase change, eventually causing errors in the read-out.


To overcome that issue, the IBM scientists applied an advanced modulation coding technique that is inherently drift-tolerant.

The modulation coding technique is based on the fact that, on average, the relative order of programmed cells with different resistance levels does not change due to drift.


About the Drift Tolerant cells:

The following advantages of substrate bias in n-channel MOS technology.

Advantages include:

Elimination of substrate injection current from localized forward biasing of diodes, improved speed and power characteristics, and a larger differential data signal on the bit sense lines.

The generator circuit avoids several pit-falls on on-chip V/SUB BB/ generation.  Circuit pumps to a known regulated voltage avoiding substrate drift with changes in substrate current resulting from changes in cycle time.

Drift will change device characteristics and degrade storage levels. A unique two-level reference scheme avoids changes in substrate bias voltage that otherwise result from the shift or back bias

Rising Prices of PETROL (Sorry for going out of the way and posting an idea of my OWN)

with ever increasing prices of PETROL i am worried if i will be able to get a JOB in the forthcoming days because for that i will need to study and for that i need to live

well PETROL prices cannot be controlled depend on INTERNATIONAL AFFAIRS

But atleast its usage can be controlled .

Very simple and secure methods such as using meters attached to vehicles can monitor the travel versus efficiency of the vehicle.

PETROL price must vary from vehicle to vehicle , person to person

Decidedly on the use , this wuld control increase of prices of other commodities atleast.

Last but not the least will try edit this post later to enter a block diagram and other possibile infos

WISHING EVERYBODY A PETROL FREE LIFE to GROW RICH this dream would come true in a few years atleast if not now for those who need to survive.
