robotic arm
A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot.
Premise
· An automatically operated hand that replaces human effort, though it may not look much like a human arm.
· Advanced high-performance robotic arms are used today in automobile manufacturing and aircraft assembly, and electronics to sort or test finished products.
· Designing, construction and fixing of automobiles may not be perfect when done by humans. So we can use robotic arms to do the work.
· Robotic arms are also used in chocolate factories for packing the chocolates into their required cases.
· Robotic arms can be used at houses as it may reduce our effort on work.
ANALYSIS
Robots are used in many fields and some of them are:
· Vehicle and car factories,
· Precision cutting, oxygen cutting, lasers, etc.,
· Mounting circuits on electronic devices (i.e. mobile phones)
· Working where there might be danger (i.e. nuclear leaks, bomb disposal)
· Surgeons are performing robotic-assisted surgeries that, among other things, can equalize little
· Jiggles and movements of a surgeon's hands when doing delicate procedures, such as microscopically aided surgery or brain surgery, etc.
· Other manufacturing, such as certain repetitive steps in assembly lines or for painting products so humans don't breathe the over spray or have to work with respirators on, working in the heat of drying and treating ovens on wood products, etc.
· Mail delivery to various mail stations throughout the buildings in large corporations. (They follow routes marked with ultra violet paint).
· To assist police and SWAT teams in dangerous situations, such as with hostages or in shoot outs and stand offs. They can be sent to the scene to draw fire, open doors, "see" the environment from a closer view point, or look in windows with cameras, etc.
· Remote procedures by a surgeon or other doctor who is unable to be there to perform the surgery in person (such as at an ice-bound Antarctic research center) or where there is a shortage of surgeons in a specific specialty and the remote surgeon does or guides the procedure from far away via robotic "hands".
· Space
· Toy (Playing ect.)
Robotic systems are used in a
number of ways such as:
1) In manufacturing - To help make stuff, faster and with more quality control;
2) In processing operations - fitted with cameras to sort foods quality;
3) In inaccessible areas - very small robots accessing places we can't go, or
space exploration missions;
4) In dangerous areas - inside nuclear reactors to check them out;
5) In the military - to keep humans out of harms way;
6) In medical environments - helping surgeons perform operations;
7) To assist disabled people - with the use and control artificial limbs;
8) To help market their products - the Honda Robot, Vacuum Robot;
9) To find out what they are capable of doing - in universities and research
organizations;
10) In toys - Very simple robotic techniques are used in toys for children.
Pretty much in my opinion they are there to do jobs, that we can't do, are not
very good at doing (high precision, repetitive work) or don't want to do.
Almost anything. Anything you can build to do something for you is basically a
robot. One definition of robot is "artificial agent"
These days most of the really
popular robots are exploring places people can't go yet and doing things too
dangerous for humans to do safely (like hunting for roadside bombs in war zones
or searching the bottom of the ocean).
Nanotechnology is finally catching on, with motors and wheels the size of
atoms.

winter sports
Introduction
|
P |
eople who live in regions that experience cold, snowy winters have long enjoyed winter sports such as ice skating, skiing, and sledding. These activities have grown immensely in popularity over the years. Today thousands of resorts cater to the winter tourist trade, and millions of people each year take winter sports vacations. Many athletes also pursue these sports competitively. The Olympic Winter Games, first held in 1924, have become one of the most celebrated sporting festivals in the world, showcasing both traditional and relatively new winter sports.
Ice Skating
The activity of ice skating has given rise to two distinctive sports: figure skating, which involves the performance of various jumps, spins, and dance movements; and speed skating and short-track speed skating, both of which are forms of racing on ice skates. Ice hockey is the best-known team sport that involves skating.
Ice skating is at least a thousand years old and probably much older. There are references to it in many of the early books of continental Europe and still earlier mention in the Norse sagas of Iceland. The first skates were made from shank or rib bones of elk, oxen, reindeer, and other animals. It is not known when the metal runner was introduced. Until the middle of the 19th century the metal portion of the skate was fastened to a wooden base or footplate and the whole of the skate was fastened to the foot with leather thongs or straps.
From such early beginnings the modern steel-bladed shoe skate was developed. Three styles are in common use today. The figure skate, which is the type best suited for general pleasure skating as well as for figure skating, has a curved, short blade with a group of sawlike teeth at the front—called a toe pick—for quick starting and stopping. The speed skate has a long, thin, flat blade that extends beyond the toe of the shoe. The hockey skate is a hard, protective boot with a short blade that is curved at the ends to allow for quick turns.
Skiing— an International Sport
Skiing was a prehistoric activity; the oldest known skis date to between 8000 and 7000 BC and were discovered in Russia. Early skis have been found in many areas of northern Europe: a 4,000-year-old rock carving depicting skis was found near the Arctic Circle in Norway, and hundreds of ski fragments that are 1,000 to 3,500 years old have been found in bogs in Sweden, Norway, and Finland. Some of the first skis were short and broad, resembling snowshoes more than modern skis. Skiing was not confined to Europe, however, as the first written references to skiing are from the Han dynasty (206 BC–AD 220) and describe skiing in northern China. Skiing was used in warfare in Scandinavia from the 13th century or earlier, and military skiing continued into the 21st century.
The earliest mode of skiing developed into the sport now called cross-country skiing. Competitive cross-country skiing began in Norway in the 1840s. Ski-jumping competitions date from the 1870s. Alpine, or downhill, skiing developed later in the mountainous terrain of the Alps in central Europe. Through the years there has been fierce competition among the skiers of various countries. Rivalries helped produce many great champions in skiing history whose style and technique have influenced millions of recreational skiers.
Downhill skiing, which attracts the majority of skiing enthusiasts today, was once limited by the need to climb the hill before or after skiing down; the building of ski lifts began in the 1930s. Skis were originally made of a single piece of wood, usually hickory; laminated construction began in the 1930s, and plastic running surfaces were introduced in the 1950s. By the 1990s skis were typically made by surrounding a foam core with wood, wrapping both layers with fiberglass combined with Kevlar, aluminum, titanium, or carbon for strength, and finally adding a plastic base.
The business of skiing began its serious growth in the 1930s and became explosive in the 1950s and '60s; huge resorts now dot the Austrian, Swiss, and Italian Alps, the Rocky Mountains, and other mountainous regions around the world.
Sledding Sports
For a swift flight over snow, tobogganing offers sport that is as exciting as skiing. Toboggans are long, flat-bottomed sleds made of thin boards curved up at the front end. North American Indians were the first to use the toboggan, the name of which goes back to the Algonquian word odabaggan. The Indians probably used the toboggan originally for carrying their loads of food and supplies through the woods in winter.
The modern toboggan is usually built of thin, straight-grained boards of hickory, birch, or oak fastened together by light crosspieces. Some are made of metal or laminated wood. The front end is bent up and back to form the hood and is braced by rope or leather thongs. The flat sliding surface is generally about 18 inches (45 centimeters) wide and from 4 to 9 feet (1.2 to 2.7 meters) long. Several persons can ride at one time, either lying prone or in a sitting position. The toboggan can be steered by lifting and twisting the front or by dragging a foot in the snow.
Tobogganing as a sport appears to have originated on the slopes of Mount Royal in Montreal in the 19th century. World competition sledding today is often described as tobogganing, but it actually involves bobsledding, lugeing, and skeleton sledding.
The sport of bobsledding involves sliding down an ice-covered run on a large, four-runner sled called a bobsled, bobsleigh, or bob. A bobsled is equipped with a long seat for two or more (usually four) people, a steering wheel or steering ropes, and a hand brake. Bobsledding developed both in the Swiss Alps and in upstate New York in the 1880s and was included in the first Olympic Winter Games in 1924. Bob runs are typically about 4,920 feet (1,500 meters) long, with 15-20 banked turns. Four-person sleds attain speeds approaching 100 miles (160 kilometers) per hour.
A luge is a small sled that is ridden in a supine position and steered with the feet and subtle shoulder movements. Dating back to the 15th century, lugeing is a traditional winter sport in Austria and is also practiced in other countries. The course used is similar to that employed in bobsledding, and speeds above 90 miles (145 kilometers) per hour are not uncommon. Lugeing became an Olympic sport in 1964.
In skeleton sledding, a small sled is ridden downhill in a headfirst, prone position. The sport of skeleton sledding developed in the 1880s on the famed Cresta Run at Saint Moritz, Switzerland. The “bony” look of the early sleds gave the sport its name. Riders attain speeds of more than 80 miles (129 kilometers) per hour. It was first contested at the Olympics in 1928.
Snowshoeing
Snowshoeing probably originated in northern Asia several thousand years ago. For North American Indians and early American settlers, snowshoes were a principal means of winter travel. They are still used by hunters, trappers, and other workers in areas where snowmobiles and other vehicles cannot maneuver.
The two basic types of snowshoes are the short, broad, tailless bear-paw and the long, narrow shoe with a tail variously named Maine, Michigan, Alaskan, etc. The bear-paw is best for rough or heavily wooded terrain, where maneuverability is most important; the longer shoe is better for more open country or for racing. Snowshoes are usually made of wood with leather lacing, although by the 1980s lightweight metal, synthetic lacing, and plastic were in use.
The snowshoe is fastened to the foot with thongs or with a contrivance so adjusted that the back of the foot rises and falls freely as if the sole of the foot were hinged to the webbing at the rear edge of the toe opening. The adjustment should always be such that the tail of the snowshoe drags and is not raised when a step is taken.
An hour's practice generally will enable the beginner to master the use of snowshoes for ordinary tramping. Running, jumping, sliding, turning quickly, and climbing are accomplishments that will come gradually to the enthusiastic snows hoer. The sport enables a person to go almost anywhere across country and to discover the breathtaking beauty of the winter landscape.
Snowshoeing as an organized sport probably began with the founding of the Montreal Snowshoe Club in 1840. Snowshoe racers, moving with a characteristic bent-knee, shuffling gait, can cover a 100-yard (about a 90-meter) course in just over 12 seconds and a mile (1.6 kilometers) in about 5 minutes.
Some Other Winter Sports
Biathlon is a winter sport that combines cross-country skiing with rifle sharpshooting. It originated in Scandinavia and was first included in the Olympics in 1960. Competitors cover a course, carrying a single-shot rifle and ammunition and stopping at four points to fire five shots at small targets. There are a variety of race types, including relay, sprint, and pursuit.
The game of curling originated in Scotland in the early 16th century. In curling, two teams of four players each slide a round stone by means of a gooseneck handle on the top over a 138-foot (42-meter) stretch of ice toward a target circle. The object is to deliver the stone closest to the center (called the house). Each player delivers two stones, which average 40 pounds (18.1 kilograms) apiece, often applying a curl to the stone's trajectory. The player's teammates use a broom to sweep the ice ahead of the oncoming stone in order to facilitate a longer slide or to adjust the arc of the curl. Blocking and knocking out an opponent's stones are important strategies of the sport. In 1998 curling became a medal sport in the Olympic Winter Games.
The rapidly growing sport of snowboarding involves sliding downhill over snow on a wide ski, called a snowboard, ridden in a surfing position. Developed in the United States in the 1960s, snowboarding made its Olympic debut at the 1998 Winter Games. Three main styles of competition exist: Alpine, freestyle, and boarder cross. Alpine events are timed and contain gates around which snowboarders must maneuver. Freestyle competitors use a large, snow-covered trench, known as a half pipe, to repeatedly launch themselves into the air and are judged on their ability to perform various acrobatic tricks. In boarder cross contests, four to six racers simultaneously navigate a downhill course containing bumps (moguls), jumps, and other obstacles.

GOLDEN FISH
ON 25 JAN 2014 WE WENT TO MANALOOR.THERE WAS MY UNCLE'S HOUSE.NEAR BY WAS A FARM WHICH HAD FISHES ALSO.WHEN WE WENT TO SEE THE FARM WE SAW MORE THAN A GROUP OF GOLDEN FISH.MY SISTER TOLD SHE WANT ONE . AND MY ANOTHER UNCLE'S ASKED," WILL YOU SELL THESE". SALES GIRL TOLD,"YES WE WILL .BUT ONE THINK WE WILL GIVE AS PAIRS "UNCLE TOLD "OK " .

How to think?
My Mind. My Thoughts. Thinking how to think?
Your mind is a powerful tool. It has the unmatched ability to create and / or to destroy the potential in you. The question or tactic of learning how to think, remains to be an incomplete mystery to every human being, till date. Even so, there are simple ways to get your mind at work, effectively and efficiently to produce practically expected results.
Here we are today to help facilitate you in thinking about 'how to think'!
Let us believe that everyone is uniquely designed to work in ways that are differently productive than
the other. Read on to know more about learning on how to think-
Develop thoughts.
Put your ideas together. Form a combination of what you think. Try to compose your thoughts and organise them mentally. Imagine and create a sequence of your thoughts. Get used to 'changing and adapting'. Improvisation is a boon. Construct your thoughts according to your situational need.
Jot the purpose.
Attach a tag to what ever you think - 'purpose?'. Find a purpose for each imagination. Purpose has to be built-in, to give birth to something valuable, useful and worthwhile with your thoughts. Define your purposes when you think. Ask questions. Investigate why you're thinking about what you're thinking. Avoid to begin thinking without any purpose.
Examine.
Categorise your ideas into different sections of the situation. By examining, you're being careful to locate the need of relevance. Discover the contrast. Determine the idea and the connection between ideas. There's no time for inappropriate thoughts.
Edit.
Proof-read your thoughts. Differentiate between the need and other stand-by elements. Justify your thoughts with accurate information. Be your own critic. Rate yourself with principles or values. Make judgments based on priority and time. Validate your imaginations before you convert it into actions or words.
Understand and Remember.
Simplify your ideas. Keep it as simple as you can understand it. It must make sense to you though. Get the meaning straight. Check if your understanding matches with the purpose of the act. Remember it by naming, matching, choosing and so on. Illustrate what you understand, may be with facts and examples. On a longer term, you must be able to remember and interpret your thoughts on your own.
Application.
Thoughts rot in your brains if they're left alone. Apply. Take it an extra mile to bring life into it. Practice, Plan and Participate. Process your thoughts into actions. Use and develop your capacity to think better. Progress in application. Healthy and positive growth by thinking, would be much required in the modernised society. So, gear up.
Learning Beyond Education. Seeking Life.
Learning Beyond Education. Seeking Life.
There is an age old saying in Sanskrit language, 'Vidyaya-amritam-ashnute', which means wisdom provides immortality. A holistic growth of a person calls for knowledge beyond mere books or even systematic educational structures. Learning values and principles beyond education holds the key to moral living. It is an essential portion of a learner's journey in seeking knowledge and seeking life.
In observing an individual's 'cycle of learning', there has been a moral vacuum created in the process of giving emphasis to attaining knowledge and cultivation of occupational skills.
By being advanced or developed in every sphere of human existence, one may gradually cease to give light on moral growth and contribution. The number of educational institutions may have considerably increased, whereas the quality lags behind miserably still. Although there is an increase in the number of educated people around, social evil still persists and hovers over many parts of our modern society.
How be it, there is hope still.
Moral education inculcates a sense of oneness and cooperation among people. More than learning about different subjects, ideologies and theories in schools and colleges, it is timely essential to build the respect and reverence on moral and ethical values of life in a systematic manner. The educational process with moral value is very humanizing in nature. In general, the elements of equality, freedom, human rights, social justice, and dignity of the individual would play a vital role in shaping up democratic qualities.
Living in a diverse cultural atmosphere, there is an absolute need for effective value education, to curb anti-social elements such as casteism, behavioural disorder, lack of unity, violent activities, murder, hatred, selfishness and so on. Perhaps, upliftment of the weaker and oppressed sections of the society can happen only when we raise the standards of value-based educational system in the country.
"There is a part of a child's soul that has always been unknown but which must be known. With a spirit of sacrifice and enthusiasm we must go in search like those who Travel to foreign lands and tear up mountains in their search for hidden gold. This is what the adults must do who seeks the unknown factor that lies hidden in the depths of a child's soul. This is a labor in which all must share, without distinction of nation, race, or social standing since it means the bringing forth of an indispensable element for the moral progress of mankind." - Maria Montessori
Applying right principles into every system of society like Family, Government/Law, Education, Communications/Media, Economics(includes Science, Technology, Business), Religion, Arts & Entertainment; will be highly influential enough to create an order and to establish healthy and incorruptible lifestyle in the present world and the future to come.
Knowledge must confer to an overall development of an individual and enable chiseling of spiritual, mental, emotional, intellectual and physical aspects of one's existence. A balanced life is what we can call it. Educators around the globe can imbibe universal ideals of respect, non-violence, love and forgiveness, peace and tolerance, co-existence and effective communication, and share it with the students or learners around.
WONDERFUL NATURE
"Our nature is very precious. We should save it."
Every hearing this. how many of them really do this? no problem.
Now we can see some interesting photos of our own nature. 
See ,this beautiful nature is spoiled because of us. We the children can try to save our environment. See the polluted environment.
see, what is the condition between the first and the last pictures of our nature?
Think about it and write your views .
"SAVE EARTH
SAVE ENVIRONMENT"
uses of TV
Television is the most impressive , useful and powerful invention of 20th century.It was invented by John Logie Baird in 1928.Approximately 80-90% of the areas of the world have T.V coverage.T.V leaves better and everlasting impression on the viewers.It is a good source of entertainment.
.We are able to know about the happenings of the world through T.V telecast. Moreover, it is better than radio and newspapers. We can listen ,watch as well as read news on T.V whereas radio and newspapers don't provide us such facilities.Various live programs are shown on T.V like cricket , football , hockey matches etc.It also shows all religious functions/festivals and regular preachings of saints and religious gurus. Many channels are there on T.V which adds to our knowledge like business, tourism , discovery channels etc.Historical movies are good for everyone to know about the history.One of the best use of Television is that there are open educational channels which help students to learn and earn while sitting at there homes.In case of emergency/urgency, one can alert/warn the citizens through T.V.Yoga programs shown on T.V have helped millions of people.Live operations are shown on T.V like when Hotel Taj (Mumbai) was attacked by Pakistani terrorists or when Laden was killed by American Navy.These all had a great impact on people.Polling during elections or counting of votes or election results are shown live on T.V.

Latitudes are horizontal lines drawn on a globe or map that go around the Earth,parallel to the equator.Latitudes are also known as parallels.
10. What are longitudes?
Longitudes are vertical lines drawn on a globe or map, that run from the North pole to the South Pole.It measures the distance of a place east or west of the Prime Meridian. Longitudes are also known as meridians.
11. What are the features of latitudes?
(i) Latitudes run parallel to each other in the east-west direction.
(ii) They are at an equal distance from each other.
(iii) All of them form complete circles, except the North and South poles, which are points.
(iv) The latitudes decrease in length as it move from the equator to the poles.
