There are plenty of people out there who claim that they are hardcore gamers, people who spend countless hours on counter strike or Team Fortress 2, but not actually trying out other genres of games. I guess you can categorize the different types of gamers out there; FPS gamers, RPG gamers, or RTS gamers. I believe that being a true hardcore gamer, you’d have to be good at every game you play and be able to pick up on the game play right away.
I figured that with this article, I would discuss about the different gamers out there and their preferred games. The reason for this is because in RPGs (role playing games), it usually requires you take a character’s part (step into their role) and plan out how the character will grow through-out the game. For instance, if you’ve ever played any of the final fantasy series game, you’d know that you’re controlling a team of fantasy characters such as wizards, warriors, archers, etc. MMORPGs are pretty much RPGs but played online. There are hundreds of thousands playing world of warcraft all over the world trying to build their character to have the best stats and have the best equipment.
Japan is a densely populated country, and that makes the Japanese market more difficult compared with other markets. If we utilize the possibilities of near-shore installations or even offshore installations in the future, that will give us the possibility of continued use of wind energy. If we go offshore, it’s more expensive because the construction of foundations is expensive. But often the wind is stronger offshore, and that can offset the higher costs. We’re getting more and more competitive with our equipment. The price—if you measure it per kilowatt-hour produced—is going lower, due to the fact that turbines are getting more efficient. So we’re creating increased interest in wind energy. If you compare it to other renewable energy sources, wind is by far the most competitive today. If we’re able to utilize sites close to the sea or at sea with good wind machines, then the price per kilowatt-hour is competitive against other sources of energy, go the words of Svend Sigaard, who happens to be president and CEO of the world’s largest wind turbine maker, Vestas wind systems out of Denmark. Vestas is heavily involved in investments of capital into helping Japan expand its wind turbine power generating capacity. It is seeking to get offshore installations put into place in a nation that it says is ready for the fruits of investment into alternative energy research and development.
The Japanese know that they cannot become subservient to the energy supply dictates of foreign nations—World War II taught them that, as the US decimated their oil supply lines and crippled their military machine. They need to produce energy of their own, and they being an isolated island nation with few natural resources that are conducive to energy production as it is defined now are very open to foreign investment and foreign development as well as the prospect of technological innovation that can make them independent. Allowing corporations such as Vestas to get the nation running on more wind-produced energy is a step in the right direction for the Japanese people.
The production of energy through what is known as microhydoelectric power plants has also been catching on in Japan. Japan has a myriad rivers and mountain streams, and these are ideally suited places for the putting up of microhydroelectric power plants, which are defined by the New Energy and Industrial Technology Development Organization as power plants run by water which have a maximum output of 100 kilowatts or less. By comparison, “minihydroelectric” power plants can put out up to 1000 kilowatts of electrical energy.
In Japan, the small-scaled mini- and micro-hydroelectric power plants have been regarded for a considerable time as being suitable for creating electricity in mountainous regions, but they have through refinement come to be regarded as excellent for Japanese cities as well. Kawasaki City Waterworks, Japan Natural Energy Company, and Tokyo Electric Power Company have all been involved in the development of small-scale hydroelectric power plants within Japanese cities.
There is a lot of exciting stuff going on in the stars above us that make astronomy so much fun. The truth is the universe is a constantly changing, moving, some would say “living” thing because you just never know what you are going to see on any given night of stargazing.
But of the many celestial phenomenons, there is probably none as exciting as that time you see your first asteroid on the move in the heavens. To call asteroids the “rock stars” of astronomy is simultaneously a bad joke but an accurate depiction of how astronomy fans view them. Unlike suns, planets and moons, asteroids are on the move, ever changing and, if they appear in the night sky, exciting and dynamic.
Like rock stars, asteroids have been given their fair share of urban myth and lore. Many have attributed the extinction of the dinosaurs to the impact of a huge asteroid on the earth. This theory has some credibility and, if it is true, it evokes some pretty startling images and foreboding fears in the current reining species on earth, the human race.
The fact that asteroids are fast moving space debris only makes their movement and activity more interesting and exciting. Unlike a moon, planet or star, the odds that an asteroid could hit the earth are entirely reasonable and in fact, there are many documented cases of small asteroids making it through our atmosphere and leaving some pretty impressive craters in the earth’s surface.
Popular culture has happily embraced the idea of an asteroid impact. The idea has spawned many a science fiction story adding the idea that alien life forms may ride asteroids to our world and start a “war of the worlds” situation. But by far, the most talked about concept that has captured the imagination and the fears of science fiction fans and the general public is of another asteroid hitting the earth that could wipe out life as allegedly happened to the dinosaurs. In fact, the movie “Armageddon” was based on this idea and the concept that somehow mankind could avert that catastrophe with technology.
But probably the best way to calm our fears and replace science fiction with science is with understanding and knowledge. The truth is, there has been a lot of study of asteroid activity and the serious scientific community has gained significant knowledge of these amazing celestial bodies. A number of probes to asteroids have been conducted which have given us a wealth of information about their composition and how we might predict their behavior.
We now know that the majority of asteroids we get to witness come from an asteroid belt that exists between Mars and Jupiter. It is from this community of asteroids that many of the notable asteroids emerged. Scientists have gained significant knowledge about the composition of asteroids and separated them into classes including class S which comes of the part of the belt that is closest to Mars, classes C, D and V which are classified by composition and a class called “Centaurs” whose flight patterns take them closer to Jupiter and Uranus.
Some of the probes NASA has conducted on near flying asteroids have performed some pretty amazing studies of these eccentric celestial bodies. In 1994 the Galileo probe got within 1000 miles of the asteroid Ida and discovered that Ida actually had its own moon.
Other probes have fired impactors into asteroids and even landed on an asteroid to produce some amazing scientific data for us. There is much to learn about asteroids in our love of astronomy and that knowledge only makes our enjoyment of seeing them in the cosmos even more exciting.
A hybrid car is such a car in which two types of motors are synchronized to provide power to the wheels. The most popular combination is the one in which the gasoline engine is assisted by the electric motor so that the gas engine is periodically shut off in order to reserve fuel.
Usually hybrid cars are subdivided into two major categories.
In the first type, only the use of electric motor propels the engine at very low speeds. The electric motor has the inherent ability to assist the engine when more power is required. It helps out the gasoline engine even while climbing or passing a steep road. The Ford Escape Hybrid and the Toyota Prius fall into the initial category.
The second of its kind requires extra horsepower for its gasoline engine to drive while in rapid acceleration or when moving up the hill. It utilizes that excess power only from the electric motor to assist the internal combustion engine. The Honda Insight and Civic Hybrid are ideal examples of the second category. These two engines do possess some resemblances as well.
When electric motor is used to assist the gasoline engine, both of the hybrids extract power from the battery depleting power, which in turn gets simultaneously self-recharged from the gasoline engine. Hence a hybrid car does not need to be plugged into a power source to recharge its battery, which is the most important aspect of hybrid cars.
Hybrid cars usually utilize sealed nickel metal hydride batteries, a technology which is popularly used in laptops and cell phones. These batteries are easy to make, cost effective and long lasting thus making it ideal for a higher valued car.
Hybrid engineers more than often have opted for unconventional design facets to maximize aerodynamics inside the engine, giving rise to its slim structure. These car units originally have very low (ultra low) drag coefficient due to sleek configurations, which make the cars slippery. All carmakers strive to reduce drag, as a vehicle with less drag requires less power as well as fuel to move.
The electrical system is monitored by an onboard computer system. The system is program controlled in such a way that when the vehicle is coasting downhill or the brakes are applied, polarity of the system is automatically reversed as the motor actually turns into an energy generating unit. This process is popularly known as regenerative where the conversion of mechanical energy to electrical energy stores up power into the battery.
All hybrid cars normally shut the gasoline engine off during road signals so as to conserve fuel reserve. The phenomenon is called idle stop characteristics. It cuts electrical consumption down during idle condition other than fuel saving and emission reduction. On pressing the accelerator paddle, the gasoline engine resumes work getting assistance from electric motor. The process being silent and seamless, the loss or delay in overall performance during this time is almost negligible.
The hybrids are manufactured by a special forging process termed as shot peeing, which reduces friction in the sidewalls of the cylinder thus increasing efficiency.
Hybrid cars, thus, by virtue of their technological advancement, exceptional fuel economy and marginal gas emissions, can be easily termed as the next generation cars
Prices for top selling luxury cars can easily top $50,000 when taxes, destination charges, and dealer prep fees are factored in. Generally, this isn’t a problem as the customer who purchases a vehicle of this renown can afford the big price tag. However, automakers have learned that there is a market for “entry level” luxury cars for up and coming buyers who want the name without paying the steep price. The dilemma for automakers is not to water down the product line, rather to offer a car that upholds the marquee without diluting its value. One such car that has successfully filled that criterion is the Jaguar X Type, the focus of this review.
Admittedly, I am biased toward purchasing American cars even through the ups and downs of the U.S. car industry. Still, I am fascinated by changes that occur in vehicles throughout the world as I know that at some point those changes will be incorporated into cars traversing North American highways. One such feature that I have seen grow more commonplace is the use of all wheel drive to power automobiles. Subaru, for years, has offered all wheel drive across their model line, but few cars – foreign or domestic – have incorporated what has chiefly been the realm of sport utility vehicles.
Photos are generally regarded as “factual,” as opposed to a drawing or painting, which would be the artist’s interpretation. Photos tend to be trusted more, because they accurately depict what was in front of the camera at the moment the picture was taken.
At least, photographs are supposed to be accurate. How easy is it to edit a photo so that it shows something different than what really happened?
The concept of photo editing is almost as old as photography itself. The first photographic images were recorded in the 1820s, and one of the first widely known edited photos was a portrait of Abraham Lincoln. Sometime in the 1860s, someone took a standing portrait of Southern Congressman John Calhoun, pasted in Lincoln’s face from the portrait for the five dollar bill, and created a historic photo of Lincoln on the spot.
Even an action as simple and innocent as cropping the picture can be controversial. Imagine a scene of the wreckage left by a tornado. If the photographer cropped out all of the damage, and focused instead on a single building that somehow survived, it would appear that the tornado hadn’t damaged very much at all.
In today’s world of digital photography, some photo editing is necessary on nearly every picture. Digital cameras have to “guess” at the proper color, contrast, and shading of the pictures they take, and proper use of photo editing tools can correct or even enhance the camera’s guesswork.
At the same time, digital photographers must keep in mind that photography–especially journalistic photography–is meant to be a record of a moment in time, and not an artistic recreation of what the photographer wants his audience to see. While editing photographs has become quicker and easier, the temptation to alter the photographs has risen as well.
