Online Electric Vehicle System (OLEV)
Korea Advanced Institute of Science and Technology has
established an Online Electric Vehicle (OLEV) system. It is an electric
vehicle which is provided energy by the road while stationary or moving.
The power is supplied to such electric vehicles by the cables fixed in
the road. A permanent direct connection is not needed by these cables in
order to charge the vehicle. As an alternative, a magnetic field is
created which is converted into electrical energy by the devices carried
on the bus. Lots of components that are present in almost every
electric vehicle currently, for instance, heavy batteries, overhead
trolley lines are left out due to this particular feature. In addition
to this, these busses are not required to stop for recharging. The
limited range is a drawback of these vehicles as they cannot ride on the
side of the road that supports them.
The bus will be given 20 kHz and 100 kW (136 horsepower) electricity at
an 85% maximum power transmission efficiency while keeping a distance of
17cm (6.7 inch) between the bus floor and the asphalt. 5% to 15% of the
entire road surface needs to be rebuilt with the embedded cables. Formerly, this technology was successfully tested in a tramcar at an
amusement park in Seoul. Now, two OLEV buses are being tested which run
between the train station and In-dong district in the city of Gumi,
South Korea. This network entails 24km (15 miles) of road. The cables in the road only turn on when they sense an OLEV
approaching and the intensity of electromagnetic field is well within
limits enforced by international EMF standards. These features have been
anticipated to lessen the exposure of pedestrians and other vehicles to
the magnetic fields and will also look after the wastage of energy.
Anger Management
Understanding Anger
The emotion of anger is neither good nor bad. It’s perfectly healthy and normal to feel angry when you’ve been mistreated or wronged. The feeling isn't the problem—it's what you do with it that makes a difference. Anger becomes a problem when it harms you or others.
Why learning to control your anger is important
You might think that venting your anger is healthy, that the people around you are too sensitive, that your anger is justified, or that you need to show your fury to get respect. But the truth is that anger is much more likely to damage your relationships, impair your judgment, get in the way of success, and have a negative impact on the way people see you.
- Out-of-control anger hurts your physical health. Constantly operating at high levels of stress and tension is bad for your health. Chronic anger makes you more susceptible to heart disease, diabetes, high cholesterol levels, a weakened immune system, insomnia, and high blood pressure.
- Out-of-control anger hurts your mental health. Chronic anger consumes huge amounts of mental energy and clouds your thinking, making it harder to concentrate, see the bigger picture, and enjoy life. It can also lead to stress, depression, and other mental health problems.
- Out-of-control anger hurts your career. Constructive criticism, creative differences, and heated debate can be healthy. But lashing out only alienates your colleagues, supervisors, or clients and erodes their respect. What’s more, a bad reputation can follow you wherever you go, making it harder and harder to get ahead.
- Out-of-control anger hurts your relationships with others. It causes lasting scars in the people you love most and gets in the way of your friendships and work relationships. Chronic, intense anger makes it hard for others to trust you, speak honestly, or feel comfortable—they never know what is going to set you off or what you will do. Explosive anger is especially damaging to children.
When to seek help for anger management
If your anger is still spiraling out of control, despite putting the previous anger management techniques into practice, or if you’re getting into trouble with the law or hurting others—you need more help. There are many therapists, classes, and programs for people with anger management problems. Asking for help is not a sign of weakness. You’ll often find others in the same shoes, and getting direct feedback on techniques for controlling anger can be tremendously helpful.
- Therapy for anger problems. Therapy can be a great way to explore the reasons behind your anger. If you don’t know why you are getting angry, it’s very hard to control. Therapy provides a safe environment to learn more about your reasons and identify triggers for your anger. It’s also a safe place to practice new skills in expressing your anger.
- Anger management classes or groups.Anger management classes or groups allow you to see others coping with the same struggles. You will also learn tips and techniques for managing your anger and hear other people’s stories. For domestic violence issues, traditional anger management is usually not recommended. There are special classes that go to the issue of power and control that are at the heart of domestic violence.
If your loved one has an anger management problem
If your loved one has an anger problem, you probably feel like you’re walking on eggshells all the time. But always remember that you are not to blame for your loved one’s anger. There is never an excuse for physically or verbally abusive behavior. You have a right to be treated with respect and to live without fear of an angry outburst or a violent rage.

15 Tonne Volvo Truck Driven by A Hamster
To exhibit the lightness of its new Volvo Dynamic Steering system, Volvo Trucks has set up a publicity stunt that uses a carrot-hungry, cute and cuddly hamster. As a sequel to its previous video featuring its president Claes Nilsson performing a stunt, Volvo released another video as component of the marketing campaign for its FMX trucks, showing that its newest steering system is so simple and effortless to handle that you can steer it with just the tip of your finger!
After training little hamster Charlie for weeks, the team placed the pint-sized rodent inside a a hamster cage/wheel mounted on top of the steering wheel, making the hamster, efficiently ‘steer’ the truck as it ran. The hamster was directed by the stunt driver Seon Rogers who handled the pedals and with a carrot as bait, guided Charlie to turn truck in necessary direction.
Volvo set out to show that the new 15-ton FMX truck could climb to the top of a dangerously steep and narrow rough quarry in Los Tres Cunados, in northwest Spain. It was a crazy experiment, as one mistake could have proven very costly for both the driver and the hamster Charlie; not to mention the damage to the awesome truck. Without a doubt, the test wasn’t as easy as shown in the edited commercial video, but it’s still highly impressive seeing a 175-gram hamster steering a 15-tonne truck up the road.
There were a few tense moments, like when the truck hit a big rock boulder sending it crashing down into the water below, but in the end Charlie managed to steer the large vehicle across the finish line. For Volvo to release the video, you know beforehand the driver and the hamster made it alive, but it still accounts for an attention-grabbing watch. It’s definitely an inspiring commercial.

History of The World's Most Favorite Game, FOOTBALL
The Game.
The contemporary history of the world's favorite game spans
more than 100 years. It all began in 1863 in England, when rugby
football and association football branched off on their different
courses and the Football Association in England was formed -
becoming the sport's first governing body. Both codes stemmed from a common root and both have a long and
intricately branched ancestral tree. A search down the centuries
reveals at least half a dozen different games, varying to different
degrees, and to which the historical development of football has
been traced back. Whether this can be justified in some instances
is disputable. Nevertheless, the fact remains that people have
enjoyed kicking a ball about for thousands of years and there is
absolutely no reason to consider it an aberration of the more
'natural' form of playing a ball with the hands. On the contrary, apart from the need to employ the legs and feet
in tough tussles for the ball, often without any laws for
protection, it was recognised right at the outset that the art of
controlling the ball with the feet was not easy and, as such,
required no small measure of skill. The very earliest form of the
game for which there is scientific evidence was an exercise from a
military manual dating back to the second and third centuries BC in
China.
This Han Dynasty forebear of football was called Tsu' Chu
and it consisted of kicking a leather ball filled with feathers and
hair through an opening, measuring only 30-40cm in width, into a
small net fixed onto long bamboo canes. According to one variation
of this exercise, the player was not permitted to aim at his target
unimpeded, but had to use his feet, chest, back and shoulders while
trying to withstand the attacks of his opponents. Use of the hands
was not permitted.
Another form of the game, also originating from the Far East, was the Japanese Kemari, which began some 500-600 years later and is still played today. This is a sport lacking the competitive element of Tsu' Chu with no struggle for possession involved. Standing in a circle, the players had to pass the ball to each other, in a relatively small space, trying not to let it touch the ground. The Greek 'Episkyros' - of which few concrete details survive - was much livelier, as was the Roman 'Harpastum'. The latter was played out with a smaller ball by two teams on a rectangular field marked by boundary lines and a centre line. The objective was to get the ball over the opposition's boundary lines and as players passed it between themselves, trickery was the order of the day. The game remained popular for 700-800 years, but, although the Romans took it to Britain with them, the use of feet was so small as to scarcely be of consequence.
The Laws.
Football has come a long way
since its first laws were drawn up in London in 1863. That historic
meeting at the Freemasons' Tavern led not only to the foundation of the
Football Association but, moreover, to the game's inaugural set of
common rules.
Although
undergraduates at Cambridge had made an earlier attempt to achieve a
uniform standard in the late 1840s - albeit still allowing the ball to
be caught - it was not until 1863 that football, a sport played down the
centuries in often-violent village contests and then embraced in the
early 1800s by the English public schools, had a fixed rulebook.
One
club represented at the Freemasons' Tavern, Blackheath, refused to
accept the non-inclusion of hacking (kicking below the knee) and
subsequently became a founder of the Rugby Football Union. However, the
11 others reached an agreement and, under the charge of one Ebenezer
Cobb Morley, 14 laws were soon penned for a game that would, in the
following century, become the most played, watched and talked about
activity on the planet.
1. Original offside rule The
offside rule formed part of the original rules in 1863 but it was a far
remove from the law as we know it today. Any attacking player ahead of
the ball was deemed to be offside meaning early tactical systems
featured as many as eight forwards, as the only means of advancing the
ball was by dribbling or scrimmaging as in rugby. In the late 1860s, the
FA made the momentous decision to adopt the three-player rule, where an
attacker would be called offside if positioned in front of the
third-last defender. Now the passing game could develop.
Despite the unification of the rules and the creation of the FA in 1863, disputes, largely involving Sheffield clubs who had announced their own set of ideas in 1857, persisted into the late 1870s. However, the creation of the International Football Association Board (IFAB) finally put an end to all arguments. Made up of two representatives from each of the four associations of the United Kingdom (England, Scotland, Wales and Ireland), the IFAB met for the first time on 2 June 1886 to guard the Laws of the Game. Then, as today, a three-quarters majority was needed for a proposal to be passed.

Then, as today, a three-quarters majority was needed for a proposal to be passed.
2. Gradual changes
In those early years, the game gradually assumed the features we take for granted today. Goal-kicks were introduced in 1869 and corner-kicks in 1872. In 1878 a referee used a whistle for the first time. Yet there was no such thing as a penalty up until 1891. In the public schools where modern football originated, there was an assumption that a gentleman would never deliberately commit a foul. Amid the increased competitiveness, however, the penalty, or as it was originally called 'the kick of death', was introduced as one of a number of dramatic changes to the Laws of the Game in 1891.

Amid the increased competitiveness, however, the penalty, or as it was originally called 'the kick of death', was introduced as one of a number of dramatic changes to the Laws of the Game in 1891.
Penalties,
of course, had to be awarded by someone and following a proposal from
the Irish Association, the referee was allowed on to the field of play.
True to its gentlemanly beginnings, disputes were originally settled by
the two team captains, but, as the stakes grew, so did the number of
complaints. By the time the first FA Cup
and international fixture took place, two umpires, one per team, were
being employed to whom each side could appeal. But it was not the ideal
solution as decisions were often only reached following lengthy delays.
The referee, at first, stood on the touchline keeping time and was
'referred' to if the umpires could not agree but that all changed in
1891.
2. Referees introduced From
that date a single person with powers to send players off as well as
give penalties and free-kicks without listening to appeals became a
permanent fixture in the game. The two umpires became linesmen, or
'assistant referees' as they are called today. Also during that meeting
in Scotland, the goal net was accepted into the laws, completing the
make-up of the goal after the introduction of the crossbar to replace
tape 16 years previously.
With the
introduction of rules, the features of the football pitch as we know it
slowly began to appear. The kick-off required a centre spot; keeping
players ten yards from the ball at kick-off, brought the centre circle.
It is interesting to note that when the penalty came in 1891, it was not
taken from a spot but anywhere along a 12-yard line before 1902.
The
1902 decision to award penalties for fouls committed in an area 18
yards from the goal line and 44 yards wide, created both the penalty box
and penalty spot. Another box 'goal area', commonly called the
'six-yard-box', six yards long and 20 wide, replaced a semi circle in
the goalmouth. However it was not for another 35 years that the final
piece of the jigsaw, the 'D' shape at the edge of the penalty area.
3. Back-pass rule changed Despite
these changes, tactics during the 1990 FIFA World Cup™ suggested
something more needed to be done. The IFAB responded in 1992 by banning
goalkeepers from handling deliberate back-passes. Although the new rule
was greeted with scepticism by some at first, in the fullness of time it
would become widely appreciated. The
game's Law-makers then struck another blow against cynicism in 1998 when
the fierce tackle from behind became a red-card offence. With a new
century approaching, the commitment to forward-thinking football could
not have been clearer.
FIFA joins IFAB
Football
fast became as popular elsewhere as it had been in Britain and in May
1904, FIFA was founded in Paris with seven original members: France,
Belgium, Denmark, the Netherlands, Spain (represented by Madrid FC),
Sweden and Switzerland. There was some initial disquiet in the United
Kingdom to the idea of a world body governing the sport it had created
rules for, but this uncertainty was soon brushed aside. Former FA board
member Daniel Burley Woolfall replaced Frenchman Robert Guérin as FIFA
President in 1906 - the year the FA joined - and in 1913 FIFA became a
member of the IFAB.
In the restructured
decision-making body, FIFA was given the same voting powers as the four
British associations put together. There remained eight votes and the
same 75 per cent majority needed for a proposal to be passed, but
instead of two each, England, Scotland, Wales and Ireland now had one,
while FIFA was given four. On the field of
play, the number of goals increased aided by the 1912 rule preventing
goalkeepers from handling the ball outside the penalty area and another
in 1920 banning offsides from throw-ins. In 1925, the three-player
offside rule became a two-player one, representing another radical
change that propelled the game further forward.
Rous rewrites the Laws
By
the late 1930s it was felt that the Laws of the Game, now totalling 17,
required a makeover. The original Laws had been penned in the language
of Victorian England and since then, there had been more than half a
century of changes and amendments. Hence the task given to Stanley Rous,
a member of the IFAB and the official who first employed the diagonal
system of refereeing, to clean the cobwebs and draft the Laws in a
rational order. The Englishman, who would become FIFA President in 1961,
did such a good job that not until 1997 were the Laws revised for as
second time. Despite football's phenomenal
popularity, there was a general agreement in the late 1980s that the
Laws of the Game should be fine-tuned in the face of defensive tactics.
If fan violence was a serious off-the-pitch problem during that period,
then on it the increasingly high stakes meant a real risk of defensive
tactics gaining the upper hand.
Hence a
series of amendments, often referred to as for the 'Good of the Game',
which were designed to help promote attacking football. They began with
the offside law in 1990. The advantage was now given to the attacking
team. If the attacker was in line with the penultimate defender, he was
now onside. In the same year, the 'professional foul' - denying an
opponent a clear goal-scoring opportunity - became a sending-off
offence.
