Awesome Watches...Seriously


These are no ordinary wrist watches. These are watches that tech-savvy people should have on their wrists but only if they the cash in their pockets or banks cause these time-giving masterpieces are not for the unfortunate.

The Tread 1 is no ordinary watch . According to Devon, it is made by a patented system called Interwoven Time Belts but reinvented.This what gives the belt it's singularity. The belts are powered by compact microstep motors providing power and accuracy, which is the important to watches. Counting 86,400 seconds per day is a task that human bestowed upon watches, certainly not an easy task. The watch is powered by a lithium polymer battery and one charge will last you a couple of weeks.


The son of a famed French watchmaker Jorg Hysek, Jorg Hysek Jr, design the stylish and awesome if I do say so myself the HD3 Slyde which has an LED screen with a sapphire crystal cover that curves to conform to your wrist. With no physical buttons, the watch has just three battery indicator lights on the side and a light sensor to automatically adapt the brightness of the screen. Everything is controlled by taps or slides on the touchscreen. So high-tech indeed.




Worldwide LHC Computing Grid






A considerable amount of people of Earth somewhat have heard about the Large Hadron Collider which is presently located in Cern, Geneva. Although the existence of such massive scientifically significant mega structure is known by a lot of people, very few are aware of one question :
If the Large Hadron Collider is collecting a lot of data for better understanding physics, what kind of supercomputer is managing the data?

The answer to that question resides in grid computing. Grid computing is unlike super computer.They are super virtual computer. A supercomputer are resources such as computers or processors connected via high speed system bus whereas super virtual computer are connected via high speed networks.

What is the Worldwide LHC Computing Grid?



The Worldwide LHC Computing Grid (WLCG) is a distributed computing infrastructure to provide the production and analysis environments for the LHC experiments.

It is managed and operated by a worldwide collaboration between the experiments and the participating computer centres. The resources are distributed across the world for funding and sociological reasons.

WLCG is therefore a distributed, or grid-based, infrastructure - the most effective solution for meeting the data analysis challenge on this unprecedented scale.

Currently WLCG is made up of more than 140 computing centers in 35 countries to process, analyze and store data produced from the LHC, making it equally available to all partners, regardless of their physical location.

Tiers

The WLCG is composed of four levels, or “Tiers”, which are made up of the computer centres. The tiers are called Tier 0, Tier 1, Tier 2 and Tier 3. These tier sites process, store and analyse all the LHC data between them.

Components

Massive multi-petabyte storage systems and computing clusters with thousands of nodes connected by high-speed networks are the building blocks of the WLCG centres.

Data processing

The challenge of analysing the volume of data produced at the LHC is an immense task. Two-stage processing using dedicated algorithms are in continuous development to reduce data 'noise', and assist in focusing on the most important data which could bring new physics discoveries.


Sadly, not enough info for the supercollider's super virtual computer since it is kept secret so that other competing organizations may reproduce such a scientific marvel but recently, the supercollider's committee decided to ask for public help to connect their pc's to the grid for extra resources.

AES Encryption


Ok guys, its been awhile since I last posted anything here but to avoid any nagging from admin I decided to up the ante for my next post. Here for all who is interested about encryption and computer security, a brief explanation about one of the basic encryption algorithm that all of them whom call themselves |-|4xx0|2 (if you don't what is this go learn about 1337). AES is simple in terms of implementation but complex in terms of production. Both simplicity and complexity is one the requirements for the AES when it was first proposed. I have to warn you th at this kind of stuff is not for the weak hearted and mind (seriously). This is a very complex thing but I know some people would have no trouble understanding.

The Advanced Encryption Standard (AES) is an encryption algorithm for securing sensitive but unclassified material by U.S. Government agencies and, as a likely consequence, may eventually become the de facto encryption standard for commercial transactions in the private sector. (Encryption for the US military and other classified communications is handled by separate, secret algorithms.)
In January of 1997, a process was initiated by the National Institute of Standards and Technology (NIST), a unit of the U.S. Commerce Department, to find a more robust replacement for the Data Encryption Standard (DES) and to a lesser degree Triple DES. The specification called for a symmetric algorithm (same key for encryption and decryption) using block encryption (see block cipher) of 128 bits in size, supporting key sizes of 128, 192 and 256 bits, as a minimum. The algorithm was required to be royalty-free for use worldwide and offer security of a sufficient level to protect data for the next 20 to 30 years. It was to be easy to implement in hardware and software, as well as in restricted environments (for example, in a smart card) and offer good defenses against various attack techniques.
The entire selection process was fully open to public scrutiny and comment, it being decided that full visibility would ensure the best possible analysis of the designs. In 1998, the NIST selected 15 candidates for the AES, which were then subject to preliminary analysis by the world cryptographic community, including the National Security Agency. On the basis of this, in August 1999, NIST selected five algorithms for more extensive analysis. These were:
  • MARS, submitted by a large team from IBM Research
  • RC6, submitted by RSA Security
  • Rijndael, submitted by two Belgian cryptographers, Joan Daemen and Vincent Rijmen
  • Serpent, submitted by Ross Andersen, Eli Biham and Lars Knudsen
  • Twofish, submitted by a large team of researchers including Counterpane's respected cryptographer, Bruce Schneier
Implementations of all of the above were tested extensively in ANSI C and Javalanguages for speed and reliability in such measures as encryption and decryption speeds, key and algorithm set-up time and resistance to various attacks, both in hardware- and software-centric systems. Once again, detailed analysis was provided by the global cryptographic community (including some teams trying to break their own submissions). The end result was that on October 2, 2000, NIST announced thatRijndael had been selected as the proposed standard. On December 6, 2001, the Secretary of Commerce officially approved Federal Information Processing Standard (FIPS) 197, which specifies that all sensitive, unclassified documents will use Rijndael as the Advanced Encryption Standard.
The Advanced Encryption Standard (Rijndael)
The block cipher Rijndael is designed to use only simple whole-byte operations. Also, it provides extra flexibility over that required of an AES candidate, in that both the key size and the block size may be chosen to be any of 128, 192, or 256 bits. (During an early stage of the AES process, a draft version of the requirements would have required each algorithm to have three versions, with both the key and block sizes equal to each of 128, 192, and 256 bits. This was later changed to make the three required versions have those three key sizes, but only a block size of 128 bits, which is more easily accomodated by many types of block cipher design.)
The original description of Rijndael is available at: http://www.esat.kuleuven.ac.be/~rijmen/rijndael/.

However, the variations of Rijndael which act on larger block sizes apparently will not be included in the actual standard, on the basis that the cryptanalytic study of Rijndael during the standards process primarily focused on the version with the 128-bit block size.
Rijndael is a relatively simple cipher in many respects.
Rijndael has a variable number of rounds. Not counting an extra round performed at the end of encipherment with one step omitted, the number of rounds in Rijndael is:
  • 9 if both the block and the key are 128 bits long.
  • 11 if either the block or the key is 192 bits long, and neither of them is longer than that.
  • 13 if either the block or the key is 256 bits long.
To encipher a block of data in Rijndael, you first perform an Add Round Key step (XORing a subkey with the block) by itself, the regular rounds noted above, and as already noted, the final round with the Mix Column step, as described below, omitted.

Now that you know a bit about this type of encryption, here is an example of what the encryption looks like kinda. You can download a pdf from:

Direct Download Skills

Imagine if there is a way to learn new things by directly download the new things into your brain.

Recently, experiment conducted by Boston University and ATR Computational Neuroscience Laboratory in Kyoto, Japan, has successfully demonstrated through stimulation on a person's visual cortex, one would be able to improve his/her own performance on visual tasks.


The researchers used decoded functional magnetic resonance imaging in order to induce a brain activity pattern from a previously determine state in a person. The method is believed can be used in inserting new knowledge through the visual cortex, eliminating the need for practice and hardwork.


Below is some description about this experiment according to NSF. Read full NSF press conference about this project here.

"Think of a person watching a computer screen and having his or her brain patterns modified to match those of a high-performing athlete or modified to recuperate from an accident or disease. Though preliminary, researchers say such possibilities may exist in the future.

Neuroscientists have found that pictures gradually build up inside a person's brain, appearing first as lines, edges, shapes, colors and motion in early visual areas. The brain then fills in greater detail to make a red ball appear as a red ball, for example."


In the press conference, Watanabe, one of the co-founder in this project said;

"The most surprising thing in this study is that mere inductions of neural activation patterns corresponding to a specific visual feature led to visual performance improvement on the visual feature, without presenting the feature or subjects' awareness of what was to be learned."

Though the project still has few limitations, this undoubtedly allows a new method of learning which can be beneficial for all mankind. Imagine having able to learn about stuff by just connecting yourself to a computer. Much like this:


I sincerely hope this i could get my hands on being the subject for this. Nevertheless, hopefully the project can give a lot of benefit to people with problem in studying.

Amondawa Tribe

You probably have never heard of Amondawa tribe, but this tribe has given scientists chaos in their theory that time was deep-rooted in human brain.


Amondawa tribe, is believed to not have the concept of time. The concept of time is so loss that they did not have words for "year", "week", "month". According to Chris Sinha, a professor at the University of Portsmouth, Amondawa people live in a world of events without embedding the time in the event like normal human should, or at least, normal to us. 


This people, rather than splitting day into specific part like morning, evening, afternoon or night, they just have two, day or night! Their season is also divided into two, rainy and dry.


Well, living without the concept of time certainly can benefit us in some way, but can you imagine if time does not exist??

The Accurate

For most people, living in constant fear may not be good, and for these people, the watch below might not be suitable for them. 

But people in some religion, especially Muslims, they will need this constant reminder because without this reminder, they may fall out of their religion's way of life. 


Design by Mr Jones Watches (MJW), the watch, which is called The Accurate, is designed so that the hour hand reads "remember" and the minute hand reads "you will die". 





You can get the watch at $157 and for special black edition, $167.

Electronic Contact Lens





University of Washington

Back in 2009, a contact lens in the works that displayed visual feedback right before your eyes, just like the 'Terminator Style' is being researched. Well, two years and a few months later, Professor Babak Parviz has a working model. He has given the new lens to rabbits, and reports complete success.
The device's display has only one pixel, but serves as a working proof-of-concept for developing more complex information lenses. A useful device would need hundreds of pixels at least, to display a short email or text message.
The lens harvests energy from an external source using an antenna and has an integrated circuit to store the harvested power and transfer it to a transparent sapphire chip with a single blue LED. Unfortunately, while the range of the display was about one meter in free space, that range was reduced to about two centimeters when it was placed on the eye.
Another of the challenges facing the creation of a Terminator-style eye display is that the minimum focal distance of a human eye is only a few centimeters. This means that information displayed on a contact lens would appear blurry. To address this, the researchers used thin Fresnel lenses to magnify the display.

Psychopath Vs Normal People

Not many people can be associated with psychopath eventhough he committed a crime. Psychopath is the term given to someone who is not able to get along with normal people. In many cases, psychopath is the one who committed a very sick crime, usually serial crimes. Annoyed by question what make psychopath different than other criminals, researchers from University of Wisconsin-Madison conducted a study to find the answer to the question.


Interestingly, in their study they've found out that ventromedial prefrontal cortex (vmPFC) connection with amygdala is reduced in psychopaths. VmPFC in human is thought to be responsible for emotion regulation such as empathy and guilt while the amygdala is responsible for social response such as fear and anxiety.

The study, is using functional MRI and Diffusion Tensor Image to see the brain of prisoners diagnosed with psychopathy. Using DTI, they found out that the white matter fibers connecting vmPFC and amygdala is reduced and the fMRI showed less activity and connection between these two areas.

Béla Kiss, Hungarian serial killer who killed at least 24 women and stuffed them in metal drum 

Joseph Vacher, known as the French Ripper who mutilated at least 11 people
According to Michael Koenigs, the assistant professor of psychiatry in the University of Wisconsin School of Medicine and Public Health, the two structures which are supposed to regulate the emotional and social response aren't communicating as they should.

Please ensure that you're not a psychopath by checking yourself in nearest hospital. Thank you.

Materializing Light from Vacuum

The idea of empty or nothingness in a vacuum is definitely wrong as in vacuum, particles are fluctuating, appear and disappear continuously. Since their existence is so brief and short, they were refer to as virtual particles.

Vacuum fluctuations may have a relation with "dark energy"

Christopher Wilson, a Chalmers scientist and his co-workers, by using this understanding, have succeeded in creating light from vacuum. The experiment, was an attempt to understand various basic physics concepts such as vacuum fluctuations which may have some connection with dark energy.

In 1970s, physicist Gerald Moore, claim that if virtual photon bounced on a mirror that is moving on the speed of light, the photon may leave its virtual state and exist in real state, which is essentially light. What Wilson and his team did was conducting this experiment in order to observe this phenomenon that is called the dynamic Casimir Effect.
Picture showing the Casimir effect in place.

Göran Johansson, Associate Professor of Theoretical Physics said that in this experiment, photons can jump from virtual state into real state simply because it lack in mass. He also said that by exerting more energy, we can create other particles such as electrons or protons.

Iris: A True Tablet PC for Anyone

Well, the world is certainly growing faster int terms of technology. Even as we speak, companies are developing their products in order to dominate the techno world.

The most famous tablet PC in the world, IPad.
Few years back, the late Steve Jobs introduced Ipad to the whole world which renders almost all companies to try inventing a tablet PC. And among the new inventions and design, a new tablet PC designed by four designers, Liu-Wei, Yao Kai-Chi, Hong Ruei-Hong & Cheng Ya-Fang, will definitely have chance in dominating the tablet PC market.

What they've designed is a transparent tablet PC, in which they called Iris. This tablet PC is using OLED screen and a transparent body, allowing the user to see through the tablet like seeing through a transparent glass. This is how Iris looks like:



Like other tablet PC, this tablet is equipped with speaker, camera and also tiny scanner. By activating the camera, according to gajitz, "this tablet can make a variety of augmented reality applications possible." Well, let's just see what this tiny thing can do that makes IPad sucks.


Well, if you want to have a mobile map that will show you where to go, definitely Iris is better. You can view the real life street with direction of where you're going. This helps especially if you're a tourist or new to some place that you've never been before.

Iris helps you in organizing your place. You can rearrange anything in Iris until you satisfied before you start arranging stuff only to find out that you don't like the arrangement.

With the help of scanner, Iris can translate whatever you're reading into your desired language. You just need to put Iris on a book, the scanner will process the words and boom, the translated text appears!

Also equipped with a sliding bar, Iris can separate the screen to allow you to do multiple works at the same time. Or if you want to share your screen with someone, just put the sliding bar in the middle and you can open different applications at the same time.

Imagine how many useful applications can be associated with Iris for example, VeinViewer. Or maybe at last, we'll have X-Ray scan just by using Iris. Well, I sincerely hope that they've already working on it because I'm gonna need one.

Smart Shirt to Make Hospital Less Scary

Being in a hospital definitely means there's something wrong with you. Especially after seeing all those big, scary machines with wires all over them. But now, thanks to a team at the Universidad Carlos III de Madrid in Spain, hospital is less scary and people are no longer attached to big wiry thingy and sit on their bed all the time.

Smart Shirt

What this team invented was something called "Smart shirt". This shirt can help doctors in monitoring patient's heart rate, blood pressure and temperature. On top of that, using wireless connection, they can perform echocardiogram (EKG) remotely, eliminating the need for staff to present during the test.


This smart shirt isequipped with GPS, well the actual reason is from it being stolen, but it is also used to track patients because they can wander around easily with this shirt. And if the patient wearing this cloth suffers from heart attack, fall, or any medical problems that require immediate attention, hospital staff can find him/her quickly using GPS. Also equipped with accelerometer, nurses or doctors can monitor if this patient is standing up, sitting, or lying down.


For every medical check up in a hospital, you'll get a free treatment for stress and a pleasing view.

Hopefully this shirt can help to make hospital less scary and more people will want to go to hospital for regular check up. But i definitely want this to be my own personal property!

New Way Of Creating Metamaterial

Well, if you have never encounter what the f*** is metamaterial, then click here

Uli Wiesner from Wesner Lab, has shown how to create metamaterial by using chemistry. The process involves in using what is called block copolymers to assemble 3-D structure in nanoscale features. 

Example of gyroid.


As you all know, polymer is substance that is made up by binding to molecules together to form a new material with new properties. A block copolymers on the other hand is the combination of two or more polymers. Now the two solid polymers will form geometric shapes with interconnected pattern that can be called as gyroid. More complex pattern or shapes can be achieved by using three polymers instead of just two. 

After this process, one of the polymers will be melted or dissolved, creating a hollow area which can be used to mold metal in nanoscale features, usually gold or silver. Now the gyroid consists of polymer and metal. The polymer is then burned, leaving the porous metal structure alone. Through all these process, Wiesner and his team researchers suggest that they can make the metal gyroid so that it can allow light to pass through. 


Maybe next time, the invisibility cloak is invisible through naked eyes, not some cameras or computers.

Using this process, the team said it is possible to create a materials with negative refractive index which is essentially metamaterial. The team now is conducting computer simulations to create the correct pattern for metal gyroid to be able to pass the light and have a negative refractive index in visible and near-infrared range. With this achievement, the world may be able to see cloaking device as has been seen in Star Trek or Harry Potter.

Augmented Reality in Medicine



Using the basic tone of Sheldon Cooper, i changed the question to "What is the scariest thing for doctors? By the way, there's only one correct answer."


The correct answer is getting sued by patient. Well, interestingly, there are many devices that were developed in order to prevent or at least reduce the error in healthcare management. Nowadays, we have robotic arms that could perform a surgery with far more accuracy than with human arms. Of course that's not the only thing. 

The video shown below is about VeinViewer, a technology developed by Christie Medical Holdings Inc a few years back. The device, which can be included in one of the greatest invention in healthcare can help doctors view the vasculatory system as if it is exposed on the skin. This will significantly helps doctors in drawing some blood for medical testing and diagnosis. 


Hopefully, in future we will have a lot more medical technologies which can help us in getting the best healthcare in any hospital. And hopefully too, more medical breakthrough will help in prolonging our life so that we can see the development of the future with our own eyes.
