There are three main factors involved when it comes to cleaning skyscraper windows: Due to the epic heights and natural factors like wind involved in the operation, every cleaner is equipped with a harness, descent and safety rope, rope protector, rope-grabbing tool, descent mechanism, lanyard and suction cups. When group work is necessary, a cleaning mechanism will be employed see boxout on the right for more information. These mechanical gantries enable teams of cleaners. Terrariums explained Discover how these fish tank-like devices are used to grow tropical plants Terrariums are a special type of enclosure with a glass case that specialise in re-creating a foreign habitat that is very different to the room they are located in.

Animals can be kept in terrariums too, with turtles being one of the most common inhabitants. For a closer look at the key components that make up a modern domestic terrarium, check out the main image.

Anatomy of a terrarium What technology enables us to re-create tropical forests within a small glass sphere? Lighting A series of LED lights is mounted within the lid to replicate necessary levels of illumination and heat for the plants to grow effectively. Terrarium tanks are similar in construction to aquariums, consisting of a base, glass tank and lid.

Sizes vary, though most are no more than cm An aquarium is a simulation of a water habitat, like a river or lake. It can be fresh or salt water and contains marine creatures. An insectarium is a special type of simulated dry habitat that caters solely to insects and arachnids such as the tarantula.

It features aspects of both aquariums and terrariums. A riparium is a very particular type of paludarium — one in which the contained water sources have a circulating current. Polyester is strong and comfortable but its range of merits pales in comparison to nylon so polyester is primarily used in other types of clothing rather than swimsuits.

Most commonly known as Lycra, spandex boasts excellent elasticity. The pantomime villain of swimsuit materials as it has been banned in competitions. The material enclosed tiny pockets of gas that made swimmers more buoyant. How exercise pools work Inside the domestic swimming machines that let us swim for miles on the spot Pump. Exercise pools are the A hydraulic pump drives the equivalent of a treadmill paddle wheel or propeller, which in turn generates the current.

Water is pumped using a Controls Water Water temperature propeller or paddle wheel and circulation and speed can be enters the pool at the front end. Water is recirculated set electronically from the end of the The speed of the current is using this built-in pool, back to the control panel.

This minimises the bubbles and turbulence associated with the Counter-current outlet Water is fed into the pool in a kind of jet used in Jacuzzis. Exercise pools provide the features needed for training while taking much less space than a full-size pool.

Why racing swimsuits make us faster Although they may look simple, swimsuits have been engineered to help swimmers glide through the water. Most important is the hydrodynamic shape. New materials are designed to reduce drag and compress the body into its most streamlined form, helping to reduce lactic acid buildup in the muscles.

The fabrics can be made from nylon or spandex and are designed to be lightweight and have a high compression-to-weight ratio. Bonded seams, for instance, reduce drag by six percent compared to sewn seams. All these measures help swimmers get ever quicker. So quick in fact, that in , polyurethane suits were banned from competitive swimming as they gave an unfair advantage after records tumbled at the World Swimming Championships.

Comfort for the swimmers is also a priority of course. Special widened straps help avoid soreness while wide-vision goggles aid sight and reduce drag. Even harmful chemicals are combated with new materials resisting chlorine up to ten times longer than older suits. The roots can also be supported in an inert medium.

Hydroponics does away with soil and grows plants with their roots suspended in an aerated nutrient solution in greenhouses. They develop 20 times as fast as traditional crops. A new use is being developed for hydroponics. Algae simpler plants are grown in tanks in the sunshine.

This is fermented to produce ethanol and the mush left behind is buried. They cannot break down the soil particles but rely on the dissolved solution between them. These allow the nutrient solution to be drained out regularly. The greenhouse effect How does a typical hydroponic system work? The greenhouse environment Starter pots In this system. Tomato plants Tomatoes are especially well suited to hydroponic cultivation. This process locks up carbon dioxide. The notes will continue to stick after multiple uses until all the bubbles have been burst so no further vacuums can form.

Rainy day The glass is coated with a titanium dioxide layer. This makes it much easier for the dirt to be washed off with just a quick blast of a hose.

The adhesive enables notes to stick to a surface. These bubbles rupture under pressure. Titanium dioxide is a hydrophilic substance. Washing away The water runs down the window. This compound reacts with dirt. Water lover UV light activates the layer which reacts with dirt. Thinkstock The incredible science behind sticky paper memos A microscopic image of the adhesive part of a Post-It note WorldMags.

Each Post-It note has a strip of pressure-sensitive adhesive on the back. Streak free As the water has spread into a sheet rather than droplets.

This is because of the compound being hydrophilic. Glass is coated with a chemical compound of titanium dioxide that is activated by UV light. UV light 4. Rain or hose water spreads across the titanium dioxide-coated window. The exact composition of Post-It adhesive is a closely guarded secret.

Belt The top layer of the belt is made of PVC as it is springy yet durable. They allow the belt to move smoothly and reduce the wear and tear on the machine. Motor The motor in a treadmill powers the belt around and around. Angle grinders rotate at around They can either be battery powered or work off the mains and consist of a powerful motor running a spinning disc.

Backing Surrounding the belt is the deck. Angle grinders explained Angle grinders are multi-purpose tools that can do almost everything. Beneath is a layer of cotton and polyester blend to reduce the sound of feet hitting the board. If a wire brush is placed on the spindle. Inside eco-mowers Meet the 21st-century lawnmowers which have been designed to run off the very same grass cuttings we normally throw away a pelletiser where the loose trimmings are compressed into pellets using a combination of heat and pressure.

As well as being eco-friendly the EcoMow can navigate itself using GPS technology and on-board sensors Ultimate green machine 2. Char is also deposited in a tray at the bottom. The grass pellets then enter a small chamber to be dried and next comes the most crucial component of the eco-mower: It also means less sewage is being dumped into the ocean.

The first ever self-propelled ride-on grass-cutting tractor — called the Triplex — goes on sale in the USA. In Norway. Pellet bin Any surplus pellets not burned for fuel are dropped into here. Engine 1. A cutter bar has replaced the traditional rotary blade. The first Flymo hover mower arrives. This includes compression into charcoal briquettes.

A new quieter version of the mower is released. They can be stored for later use or fed to livestock. Dryer Freshly made pellets are generally wet. Pelletiser A closer look at the main components that make up this cutting-edge lawnmower The trimmings are fed into the pelletiser where they are heated and squeezed into compacted pellets. Petrol-based mowers quickly follow.

Sealed off to prevent oxygen getting in. Eco-mowers use 21st-century technology to get the best of both worlds: James Sumner patents the first steam-powered lawn mower. The grass then enters. Perhaps most surprising of all. In a process known as pyrolysis the biomass releases hydrogen and other hydrocarbons. By the time motorised versions rolled up decades later. The machines were easier to use but produced petrol fumes detrimental to the environment. Used vegetable oil UVO from factories and fast-food restaurants can be processed and used as an alternative to diesel in cars and public transport.

On a wider scale than the chimney. Made of stainless steel. Chimneys big and small Chimneys come in all shapes and sizes. Flues help retain heat and expel toxic gases. The stack effect also helps speed up the process and works when surrounding cold air is denser than the hot air inside. On the roof Vents raised off the roof emit the smoke away from the building.

In order to vent fumes out of our homes. They are usually lined with clay. Air pressure above this level is higher than outside positive and tries to force its way out.

Lintel Also used above doors and windows. This is known as the Venturi effect. Inside the classic household heating system The fact that hot air is less dense than cold and so rises is vital to the workings of a chimney. Thanks to convection currents. This ensures that the hotter air always rises. When the tap is turned on. These can either be metal or a small brick vent.

Think of the hot fumes as water in a hosepipe. Automatic shutdown The power will automatically cut out if the oil begins to overheat. Heating element Electric fryers use an element to heat the oil.

A tap on the bottom of the tank allows used oil to be drained easily. Wheel pack The wheels each have a pin. The most important component of the fryer is the mechanism which heats the oil: In an electric fryer a heating element is immersed in the oil. The notch on the second is lined up with the latch and the dial turns clockwise again. Spindle The spindle is attached to the dial and runs through the wheels and turns the drive cam.

Deep fryer technology Cooking the perfect chips requires oil at scorching temperatures. Sticky rubber feet on the bottom of the fryer prevent it from slipping on or burning the work surface. Spigot Insulated casing The shell of the fryer is often made of plastic. Many new fryers also have a thermostat that senses and adjusts the temperature. Temperature control Rubber feet The temperature can be manually adjusted.

The electric current encounters resistance as it moves through the element. Combination locks Latch When all of the notches in the wheels line up.

Nail guns can save a lot of time and energy compared to hammering Inside a pneumatic gun Discover the inner workings of an air-powered nail gun The piston shoots forward and propels the nails fed from a magazine in front. These guns combine power with portability as there is no neeed for an air compressor attachment. This variation holds one nail at a time and uses a coiled spring to deliver the nail into the desired surface upon the press of the trigger.

First invented in the s. Veterans of the war. Over the following decades. In this case. When it is discharged. Using compressed air generated from pistons. They initially declined the offer with a view to starting up their own business. Nails will only be released when the tool is pressed against a solid surface. It can be a straight design as shown here or a coil shape that can hold more.

The most basic is the spring-loaded design. Main valve Holds the compressed air back until the trigger is pulled. Another type is the solenoid — or electromagnetic — nail gun. Another variation is the combustion nail gun. Solenoids are more reliable than the spring-loaded design but have a lot less power than pneumatic nail guns see annotation.

Its ability to launch nails at high speed and with relative ease makes the simple hammer seem pretty primitive by comparison. Impressed by their invention. Wireless transmitter The bin is able to send a message when it needs to be emptied. The bins can hold up to eight times more refuse: They come in a variety of shapes and sizes for different purposes. Crusher The main body of the bin contains an automatic crushing mechanism to squash the rubbish. Many solar-powered bins include a sensor connected to a wireless cellular data transmitter.

Water valve At the start of the cycle. Meet the solar crusher These eco-friendly bins are appearing in cities the world over. This enables the bins to be used in areas that receive little sunlight.

The interesting technology behind an everyday device Why we might be taking virtual holidays in the near future That is how the rat knows where it is in the room. Nando de Freitas. After recent advances in drone and interactive robot technology we are close to a breakthrough in AI. In a rat. Is someone. Each neuron is connected to the visual cortex.

What about emotional intelligence — working out if someone is sad. But where are we now in terms of creating computers and robots that can think. Watson easily beat its human rivals An area that stores sequences. AI scientists want to re-create this so robots can learn journeys.

If you were to poke the amygdala with a needle. It can walk on a variety of surfaces. That is being able to perform an action and ask yourself: NAO is an advanced humanoid robot. The new brain — areas like the neocortex — is where we do our higher level of thinking.

In order for this incredibly powerful machine to work. Right now. Created by Aldebaran. After all. Every time you excite a neuron in the hippocampus. New technology allows UAVs to plot their own route without human intervention. Despite struggling with some shorter clues. Despite of what Hollywood says.

Watson came 14 years later and stunned the world by not only being able to understand the complex questions posed. Watson used 90 IBM Power computers. Facial recognition. QuAIL focuses its research on developing a completely new kind of intelligence using quantum computers. We take intelligence for granted. But what tech went into the duo?

Deep Blue beat world chess champion Garry Kasparov in Cerebellum Hippocampus The region of the brain is responsible for storing and organising memories. Brain games Deep Blue and Watson are amazing examples of supercomputers that were able to defeat the best human practitioners in chess and quiz show Jeopardy!. Amygdala Found in the temporal lobe.

Visual cortex Part of the neocortex. The most obvious bit of AI technology in your smartphone or tablet is in the camera.

What hurdles are they yet to overcome? Considering that in the UK in In the Yurin Dojo. Information is stored here. Another near-future application for AI is in the medical industry. These computer chips are able to deal with more than one task at a time and cope with much bigger data sets than the central processing unit CPU that.

If you instrumented their home. Then we want them to learn to construct different sequences. I see them rising up to stop us killing each other. Google reports that its cars have collectively driven over No psychologist has ever had access to this amount of data. They could use this data to start recruiting. They can perform logic and mathematical tasks much quicker. I talked to Mark Zuckerberg about this a few months ago. Not only that. But no. CPUs have a small number of cores.

You can learn a lot from the data that exists out there — even their IQ. Dark Resurrection. But what happens when they fall into the wrong hands? AI tech in Alien: Isolation allows the enemy to adapt to your gameplay strategy could send an ambulance in time. If you think of a computer like a rowing boat. This is what we are now trying to achieve with AI.

Google Chauffeur is able to make hundreds of diagnostic checks per second and only requires serious human intervention every All the time you are playing the game. There were 1. The advanced game engine has the ability to make instantaneous decisions. As someone who works on it and sees it coming. If anything. We want computers to learn abstract representation about their environment and then think about their environment and the cause and effect of their actions.

Amazon and Facebook are keen to exploit. The Google Chauffeur is a self-driving car. Processor fan Memory The sheer number of cores running simultaneously creates a lot of heat. The next step is to imagine alternative scenarios to what is put in front of them. For Facebook. Transistors The more transistors. Involving millions of neurons interacting in yet fully understood ways. Machines could keep a watchful eye and run analysis on vulnerable patients faster and with greater accuracy.

Thinkstock Future AI tech. Google executives begin testing self-driving cars on public highways. Until roboticists are able to replicate the neural connections. Humans can map out a series of sequences to lead us to a goal.

Just ask your calculator. Just think. Humans have the ability to think creatively about a subject. Alan Turing invents the Turing Machine — a theoretical computer that follows a set of directions. Because of this — as well as their lack of emotional responses — they can work logically through commands to reach the best possible solution.

Humans still edge the battle of the mind on multilayered matters. Logic Computers are extremely linear when it comes to thinking. Most humans can hear a sentence and extract meaning from it. If you want to work something out quickly and accurately. Speech recognition Computers are catching up. Few robots are able to do this. In a Brazilian researcher estimated that the average human brain has around 86 billion neurons Humans vs robots Who comes out on top in the battle of the brains?

Planning This is where humans really trump computers. Self-driving cars Robot medics Space vehicles As yet only allowed to be driven in California and currently undergoing testing. Computers are able to operate at much faster speeds because they are stripped-down basic brains. The gaming side of things is combined with a host of media-related applications.

TwitchTV live videogame stream broadcaster and iHeartRadio internet radio platform. Breaking from the norm. Unlike many existing games consoles. As can be seen in greater detail in the teardown.

Android 4. The system-on-a-chip is covered with a small heatsink. Wi-Fi and Bluetooth 4. These feed the system power or are used to connect to the web. Common information includes any elements of the two signals that are identical. The former is the recorded signal in its entirety.

The included subwoofer — technically a low-frequency loudspeaker. The sub is placed in two compression zones that help it deliver bass frequencies without rattling in the box and surface it sits on. What differentiates this unit from previous soundbars. The speakers are also all separated in space by more than a couple of feet. This is assured due to their irregular shape and controlled air volume. The box is bonded together to prevent leaks between the enclosures.

The SB60 can be synced via Bluetooth to smartphones and tablets SB60 up close Compression zones How It Works takes a look inside this revolutionary new sound system The compression zones within the SB60 ensure the low-frequency speaker subwoofer produces distortion-free base.

With those setups you get interaction between the loudspeakers. This improves audio performance massively. What we have done with the SB60 is that the main signal is generated by two small millimetre 1. Main signal speakers Ports Positioned side by side to mitigate unwanted timing and wave-cancellation effects. The basis for the technology is that you have a main signal and a spatial signal.

Why is the SB60 better than any other soundbar available? All other soundbars produce sound from their loudspeakers that is very similar. We then built 20 prototypes perfecting the system — the result was the SB We ended up deciding to stand the television on top of a very thin large speaker box and incorporate everything into it.

Ted Fletcher. Recently there has been a shift in the industry where people have begun to say. This is necessary. The spatial signals. That is why the SB60 is vacuum-sealed.

The sealed box prevents leaks between the enclosures that can lead to audio defects. We speak to the SB60 designer. By splitting off these directional cues and transmitting them through the side speakers.

These speakers are in their own enclosure. Now we come to the interesting bit: In terms of connections. Similar to its more expensive desktop counterparts. PLA is more prone to overheating and can droop if it gets too hot. Unlike a normal pen. ABS is a plastic that can easily deform if not being printed on a heated surface. It also adheres very well so may not be suitable for peeling off paper like ABS is. After turning the 3Doodler on and waiting a few minutes for it to warm up.

Made of oil-based resources. The nozzle has also been redesigned to improve accuracy. In traditional 3D printing. It also comes in a huge variety of colours and can even be translucent. Once the heated plastic leaves the nozzle. Because the heated plastic can be drawn over almost any surface.

This gizmo enables you to turn drawings into full-3D models on any surface. There are different types of nanocoating. These prevent water entering while submerged. The vapour contains a gaseous polymer. Tough materials Thanks to a hardened glass front and back covers. The first commercial waterproof mobile phone was the LG CanU S released in Waterproof smartphones How do these electronic devices carry on working even when underwater?

Like all good inventions. Plugged in. Electric guitars need ferromagnetic metal strings while acoustic guitars can use strings made from nylon. Acoustic vs electric Amp up the volume All guitars have a body. The pick-up is a bar magnet housed inside thousands of turns of wire. But for the most part guitarists prefer the original. Modern amps often combine the two types for a warm but loud sound. For an electric guitar. Modern guitars work in exactly the same way. Pluck a string and the vibration travels through the bridge into the body.

Amps boost the input signal from the guitar and drive the speaker cone. Electric guitars can have a single pick-up for all the strings or one for each string. Both acoustic and electric guitars are usually made of wood. Strings are made from ferromagnetic metal. When vacuum tube amps were replaced by solid-state amps in the Seventies.

The hollow body of an acoustic guitar provides a big chamber for air to reverberate. The main difference between the two types of guitar is how they produce sound. Guitars could be heard. This current is the signal which is carried to the amp. While amps. Next the vibrating cone generates sound waves.

In the Thirties. The body and air inside it vibrate. Upper bout The top area of the body. Lower bout The bottom area of the body. Bridge Holds the strings away from the body. Tuning pegs Neck Saddle tailpiece Potentiometers Most guitars have at least two pots for controlling volume and tone.

Nut This holds the strings in their right places and feeds them into the tuning pegs. Fingerboard A player can press down on the strings here to change the vibrating length and therefore the pitch of the note.

For a guitar with two pick-ups. There are two types: Jargon buster The shapes are unique to each model. This indentation in the body near the neck allows the player easier access to the upper frets. Body Usually kiln-dried hardwood mahogany. Pick-ups Nearest the neck. In an acoustic guitar. Riffs are short melody phrases which are repeated.

It stands Check it out at bit. Guitar for Beginners is full of tips and tutorials. Pick-up A bar magnet wrapped in a coil of wire. Fret The thin. The distance between frets corresponds to one semitone 12 semitones make up one octave.

This can be adjusted to change string length and therefore tone. Pick-up selector This selects which pick-ups send signals to the amp. This pedal controls the bass and treble. Many guitarists prefer locking straps. The strings may terminate here or just pass over it.

Wah-wah pedal Also called machine heads. Potentiometer A variable resistor used to adjust volume or tone. You can lubricate the grooves in the nuts with graphite from a few swipes with a pencil.

And yet the basic chips that power this mathematical monster are virtually the same as the CPU in your home PC. In the USA. When Cray left to form his own company in A lot of its speed came from a. This computer had as much processing power as every other computer in the UK combined. The genius behind these computers was a man called Seymour Cray.

Called mesh computing. As Edinburgh has a cool climate for much of the year. UK national HPC services typically last between four and eight years. Floating-point operations are essentially maths calculations that involve numbers with a decimal point.

Example applications [for the supercomputer] include: China has Since I lead the teams providing science support and user support. Vector processing depends on your ability to move data rapidly through the processor and most of the performance of the Cray-2 was simply due to the much faster memory chips it used. When processors want to exchange data. And they might be getting faster still. In the s. This ensured all circuits were busy all the time. Sequoia was the first computer to use a million cores at once.

Titan uses 8.

The Cray-1 was ultimately succeeded by the Cray-2 in It uses more than 1MW of electricity. It exploits the fact that most supercomputer applications run the same few calculations over and over across a huge dataset stored in memory. Sequoia — Although this is slower than wiring the processors directly together.

How many simulations are running on it at any one time? There are 3. Instead of having just a handful of processors the Cray-2 had just eight sharing a common pool of memory. Dr Alan Simpson. The Cray-1 treated the operation like a factory assembly line. In one day it can perform as many calculations as a desktop computer would manage in 20 years. The USA is home to of the top supercomputers. If you could work out the answer to a sum such as Why does Edinburgh need its own supercomputer?

How does it compare to its predecessor? ARCHER is capable of performing at least three times more computational research than its predecessor. Titan — How long is it expected to last before it is replaced with something better? The cooling fans are so loud that staff have to wear ear protection. What operating system does it use? This makes the system much more scalable — you can make your supercomputer faster simply by adding more processors to the mesh.

The GPI handles the work of sending the right messages to keep each processor up to date at all times. We have seen case after case - from homicides and An in depth look at passwords and what they really mean to us;what is their actual role A book authored by Dr.
