Top 10 Graphic Cards




Are you interest in gaming?Then this will be a useful article to find out about the most important peace in a gaming pc.For a real gaming it needs a High-Performance Graphic Crad.If you have a super-high resolution monitor, for instance, you're going to need a high-end graphics card to make the most of it.But the problem is,The finest is the most expensive.Below article will show you the fastest and best Graphic Cards.Just remember to think carefully about how you match your graphics card with the rest of your PC.

1. Nvidia GeForce GTX Titan X




Price: £870


Oh yeah guys it's not cheap,not even close but this is the fastest and the finest single-GPU graphics card on the planet.This is clearly, undeniably, indisputably the best single-GPU graphics card you can buy.Nvidia has created Titan card purely for gaming.It is master piece of technology.There are cards with two GPUs on board that can better it in some tests. But they are also less reliable.

2. Nvidia GeForce GTX 980 Ti




Price: £550


This one almost as fast as the Titan X but less expensive.If you want the best performence you don't need to pay every single penny you have.The GTX 980 Ti brings you pretty much High-end graphics as Titan X  but comes in at around one third cheaper.I know guys it's expensive and nowhere near as good value as the GTX 970 below.

2. Nvidia GeForce GTX 970




Price:£255


This one also takes the second place on the list because it's fine and good as the GTX 980 Ti.GTX 970 will grunt all the graphics you will ever need.This is a stupendously powerful graphics card based on what we think is the best 3D tech currently available – Nvidia Maxwell architecture.The 970 isn't exactly cheap but it is a better way to feel real gaming,ecspacially in 1080p or 1440p.


3. AMD Radeon R9 290




Price: £220


The third place on our list,going to AMD s.This one is a proper high-end GPU at a price you can (possibly) afford.The R9 290 is a proper high-end bruiser, complete with a monster 512-bit memory bus and 4GB of graphics memory – all the better for running at high resolutions providing a bit of future proofing.

4. AMD Radeon R9 280




Price: £150


This one is old but still better in 1080p gaming.The R9 280 has cut-down flagship theme .What was once the Radeon HD 7970 has been, in effect, rebranded R9 280.You will get 1,792 stream processors, a 384-bit memory bus that even Nvidia's GTX 980 can't match and a decent 3GB lump of graphics memory for an eminently reasonable £150.AMD Radeon R9 280 great choice for slick 1080p gaming. It's not a bad choice for 1440p gaming also.

5. Nvidia GeForce GTX 770




Price: £220


Nvidia GeForce GTX 770 has Nvidia's awesome new Maxwell architecture. But it still offers great performance at standard clockspeeds and usually overclocks like a monster. At launch a couple of years ago, the 770 was priced well above £300 and was very nearly as quick as PC graphics got. Today, it remains a seriously speedy card, but it's yours for not much more than £200.


6. Nvidia GeForce GTX 960




Price: £150


The Nvidia GeForce GTX 960 is a more affordable version of its killer Maxwell graphics architecture, but still absolutely aimed at full-featured gaming, right down to its 1,024 CUDA cores. There is, however, a snag. Nvidia has seen fit to bequeath the 960 with a stingy 128-bit memory bus. That makes it a very hard sell for high resolution gaming including anything beyond 1080p.


7. AMD Radeon R9 270




Price: £115


From AMD Radeon R9 270 you can have a graphics based on exactly the same AMD technology as seen in both of the latest gaming boxes for not a great deal more than £100. Except this AMD board packs 1,280 of those all-important shaders, to the Sony PS4's 1,152 and the Xbox One's measly 768 cores. Nice. What's more, the 270 gets one over on Nvidia's GTX 960, too, thanks to its pukka 256-bit memory bus. All round, it's a very nice little package for the price. Our only real worry is whether 2GB of graphics memory is truly good enough these days.

8. Nvidia GeForce GTX 980




Price: £430


A seriously sweet card, assuming you can afford it.The Nvidia GeForce GTX 980 is one hell of a graphics card, beaten only by Nvidia's own Titan X beast, a card that costs almost twice as much.The 980 is really a mid-range graphics chip. If the 980 is quick, who cares how that is achieved. However, the telltale that gives away the 980 arguable mid-range status is a relatively stingy 256-bit memory bus, a feature AMD matches on its lowly R9 270 board for a quarter the price.

9. AMD Radeon R9 295 X2




Price: £500


The AMD Radeon R9 295 X2 a bonkers dual-GPU board that might just make sense.The AMD Radeon R9 295 X2 is over £300 cheaper than Nvidia's mighty new Titan X board. But it beats it in most benchmarks. The explanation, of course, is that the 295 X2 is a dual-GPU card and uses AMD's CrossfireX technology to get them working together to produce mega frame rates. The problem, which isn't unique to AMD but is also shared by Nvidia's similar SLI tech, is that running multiple GPUs doesn't always work. And when that happens, you suddenly have a £500 card that's giving your about £250's worth of performance.

10. Nvidia GeForce GTX 750Ti




Price: £100


The Nvidia GeForce GTX 750Ti is no big-bandwidth beast with a memory bus a mile wide. But it was the very first card to appear with Nvidia's incredible Maxwell graphics tech. And that means it definitely punches above its weight. For a card with just 640 CUDA cores (remember, the new Titan X has over 3,000), it does one hell of a job. Definitely don't try gaming beyond 1080p and definitely don't expect to play with every eye-candy option cranked up. But if you keep your expectations realistic, you might just be surprised at the amount of gaming grunt on offer for just £100.

Hybrid  Vehicles




A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine+electric motor. As a example present most of hybrid vehicles are using  diesel engine and electric battery power as the power sources. Other means to store energy include pressurized fluid.

How hybrid vehicles works



Hybrids-Electric vehicles (HEVs) combine the advantage of gasoline engines and electric motors. The key areas for efficiency or performance gains are regenerative braking, dual power sources, and less idling.
·         Regenerate Braking. The drive train can be used to convert kinetic energy (from the moving car) into stored electrical energy (batteries). The same electric motor that powers the drive train is used to resist the motion of the drive train. This applied resistance from the electric motor causes the wheel to slow down and simultaneously recharge the batteries.
·         Dual Power. Power can come from either the engine, motor or both depending on driving circumstances. Additional power to assist the engine in accelerating or climbing might be provided by the electric motor. Or more commonly, a smaller electric motor provides all of the power for low-speed driving conditions and is augmented by the engine at higher speeds.
·         Automatic Start/Shutoff. It automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed down. This automation is much simpler with an electric motor. Also see dual power above.

Types of a hybrid vehicles


Parallel hybrid




In a parallel hybrid vehicle an electric motor and an internal combustion engine are coupled such that they can power the vehicle either individually or together. In parallel hybrid vehicles most commonly the internal combustion engine, the electric motor and gear box are coupled by automatically controlled clutches.   For electric driving the clutch between the internal combustion engine is open while the clutch to the gear box is engaged. While in combustion mode the engine and motor run at the same speed. The using mode of these power sources are depending on the way of driving.

Mild parallel hybrid




These types use a generally compact electric motor, usually about 20KW or higher, to provide auto-stop/start features and to provide extra power assist during the acceleration, and to generate on the deceleration phase. As a example when you are driving it provides power and when you are driving in neutral gear the car regenerates the electric power from car wheels.

 

Power-split or series-parallel hybrid



In a power-split hybrid electric drive train there are two motors: an electric motor and an internal combustion engine. The power from these two motors can be shared to drive the wheels via a power splitter, which is a simple plantery gear set. The ratio can be from 100% for the combustion engine to 100% for the electric motor, or anything in between, such as 40% for the electric motor and 60% for the combustion engine. The combustion engine can act as a generator charging the batteries. On the open road, the primary power source is the internal combustion engine. When maximum power is required, for example to overtake, the electric motor is used to assist. This increases the available power for a short period, giving the effect of having a larger engine than actually installed. In most applications, the combustion engine is switched off when the car is slow or stationary reducing curb side emissions.

 

Series hybrid


A series- or serial-hybrid vehicle is driven by an electric motor, functioning as an electric vehicle while the battery pack energy supply is sufficient, with an engine tuned for running as a generator when the battery pack is insufficient. There is no mechanical connection between the engine and the wheels, and the purpose of the range extender is to charge the battery. When describing cars, the battery of a series hybrid is usually charged by being plugged in - but technically a series-hybrid allows for a battery to only act as a buffer (and for regeneration purposes), and for the electric motor's power to be supplied constantly by the supporting engine.

 

Plug-in hybrid electric vehicle (PHEV)


Another subtype of hybrid vehicles is the plug-in hybrid electric vehicle(PHEV). The plug-in hybrid is usually a general fuel-electric (parallel or serial) hybrid with increased energy storage capacity, usually through a Li-ion battery, which allows the vehicle to drive on all electric mode a distance that depends on the battery size and its mechanical layout (series or parallel). It may be connected to mains electricity supply at the end of the journey to avoid charging using the on-board internal combustion engine. For some users, this type of vehicle may also be financially attractive so long as the electrical energy being used is cheaper than the petrol/diesel that they would have otherwise used. Current tax systems in many European countries use mineral oil taxation as a major income source. This is generally not the case for electricity, which is taxed uniformly for the domestic customer, however that person uses it. Some electricity suppliers also offer price benefits for off-peak night users, which may further increase the attractiveness of the plug-in option for commuters and urban motorists


 

Charging


The optimum charging window for Lithium ion batteries is 3-4.2 V. Recharging with a 120 volt household outlet takes several hours, a 240 volt charger takes 1–4 hours, and a quick charge takes approximately 30 minutes to achieve 80% charge. 3 important factors-distance on charge, cost of charging, and time to charge. In order for the hybrid to run on electrical power, the car must perform the action of braking in order to generate some electricity. The electricity then gets discharged most effectively when the car accelerates or climbs up an incline. In 2014, hybrid electric car batteries can run on solely electricity for 70–130 miles on a single charge. Hybrid battery capacity currently ranges from 4.4 kWh to 85 kWh on a fully electric car. On a hybrid car, the battery packs currently range from 0.6 kWh to 2.4 kWh representing a large difference in use of electricity in hybrid cars.

Hybrid vehicle emissions



Hybrid vehicle emissions today are getting close to or even lower than the recommended level set by the EPA (Environmental Protection Agency). The recommended levels they suggest for a typical passenger vehicle should be equated to 5.5 metric tons of carbon dioxide. The three most popular hybrid vehicles, Honda Civic, Honda Insight and Toyota Prius, set the standards even higher by producing 4.1, 3.5, and 3.5 tons showing a major improvement in carbon dioxide emissions. Hybrid vehicles can reduce air emissions of smog-forming pollutants by up to 90% and cut carbon dioxide emissions in half. More fossil fuel is needed to build hybrid vehicles than a conventional cars but reduced emissions when running the vehicle more than outweigh this.

How Make A Water Rocket In Easy Way

Making A Water Rocket





Today I'm going to show you how to make a water rocket.It's pretty easy but don't get screwed while you are making the rocket launcher.So be careful and fly the rocket safely under the inspection of a elder.

First You Will Need These Materials


1/2 inch PVC pipe about 8 ft
2 X T-bonds
4 X End Caps
Bicycle Valve
2 X 2L Bottle
Pair of scissors
PVC Glue
Dutch Tape
Knife(Be careful)

Step 1


First get the 2L bottel and cut the top edge like down below to make the nose of the rocket.



Step 2


Then glue that piece to the other bottle's footer.Then remove the cap of the uncut bottle and make a hole which is suitable to place the bicycle valve.Be careful on this point because after placing the bicycle valve the hole should be 100% air-tight.Otherwise the rocket won't launch if the pressure leaks.If the pressure is leaking add some PVC glue and seal around the hole from inside and outside.

Step 3


Now set the cap tho the bottle again.Make some fins to the rocket and glue them to the rocket like this.(You should not cut the  bottle like this,only you have to do is glue them to the rocket)



So now the rocket is finished.Now it's looks like this one..



Now it's the time to make the launcher.It is harder to explain like this.So I believe it will be easy to under stand from a video clip.Don't be afraid,just easy steps and just carry on.

So lets see how to make the rocket launcher 




So now the Water Rocket is finished and it's the time to have a fun.As i said be careful,don't hurt others..Pump the air to the rocket and release it.
And I hope you will have a great fun..
