Real-time Neural MPC: Deep Learning & Model Predictive Control Framework

Pooja Kashyap

Model predictive control (MPC) is a powerful technique that has gained popularity in recent years for controlling the movements of robotic agents. It involves using a model of the agent’s dynamics to predict its future behaviour. Followed by optimization of this behaviour to achieve a desired goal while also satisfying a set of constraints. MPC algorithms are capable of handling complex scenarios and can consider various factors such as the agent’s physical constraints, environmental conditions, and the dynamics of other objects in the environment. This makes MPC a popular choice…

Ushering An Era of Quantum Computers with Built-in Optics: The Qubit Technology

Pooja Kashyap

Quantum computers are hypothetical devices with higher computational power than a traditional computer. The classical system involves bits as the smallest unit of data, that is represented by 0 or 1, while quantum computers are made up of quantum bits, also known as qubits. Unlike the conventional computer, where a bit has to be either 0 or 1, quantum mechanics grants a qubit to be in both the states at the same time. A qubit would be represented as 0 and 1 simultaneously,  a hallmark which is rudimentary to quantum…

Google’s First Quantum Computer: A Combination of D-Wave and Universal Gate-Model

Pooja Kashyap

Quantum logic gate based on qubits is what most of the quantum computing labs is working on to make the product a reality. However, these labs show no or less confidence in companies like D-Wave, the Canadian based that came out with world’s first commercially available quantum computer functioning on 128-qubit chipset, in 2011. Lately, in an interesting turn of events, Google went a step ahead by hiring a team of researchers for building their initial Google quantum computer using quantum annealing as per the D-Wave approach than the conventional…

Magneto-Optical Storage: The Next Generation of Plastic Computers

Pooja Kashyap

In an effort to replace silicon chips with flexible plastic within gadgets like computers, cellular devices and related systems, researchers from University of Iowa and New York University have come up with an alternative to the high capacity storage technology. During the fiber optic transmission, it is easier and convenient to encode data in light while magnetism helps in storing information with an unlimited expiry date. With the proposed technology, converting information from one form to another is a critical issue. Since, the energy cost for this process is insignificant…

Silicon Photonics Chip Mimics Human Brain

Pooja Kashyap

Researchers from Ghent University came up with a breakthrough approach by demonstrating processing of information on a chip, mechanism of which was based on the functioning of human brain. Artificial neural networks or the bio inspired technique has been used in the past to bring about complex tasks which otherwise would have been tricky to solve by rule-based programming like computer vision and speech recognition. The researchers applied 16 nodes of neural network directly in hardware with the help of silicon photonics chip. Unlike the traditional computer chips that require…

Cybathlon 2016: The Championship for Robot-Assisted Parathletes

Pooja Kashyap

ETH Zurich in collaboration with the Swiss National Competence Center of Research in Robotics have attempted to take Paralympics to the next level by coalescing the conventional prosthetics with robotics. There has already been an incremental improvement with the equipments being employed by the players in the Paralympic Games including but not limited to prosthetic limbs and swimsuits. If we talk about the props like bows & arrows, cycles, wheels, we would agree that taking these equipments to the higher level of proficiency is not a difficult job than enhancing…

New Computer Vision System: Emotion Recognition

Neha Shukla

Everyone, in some point or the other in life, must have faked of being in pain or being ill, to escape from going school, college, office or so on. We humans are not always correct to distinguish a fake emotion from the genuine one. Lately, researchers have developed a computer system that can easily distinguish when an individual is genuinely in pain or is just faking it away more accurately than the humans.

How To: Improve PC Performance For Win OS

Pooja Kashyap

Lately, I have noticed that my machine with Win OS is running slow. Though this is not a general problem but happened recently so I worked along the following strategies. It helped me improving my machine’s overall performance. I hope the following eleven steps might serve you well too in case any of you are facing the same issues. 1. Disk space: At least 15% of the storage space must be kept free as it helps in efficient running of the machine. How this can be done? Go to My…

Computer Noises Now A Gateway To RSA Key Extraction

Pooja Kashyap

Since the inception of RSA public-key encryption in 1977, it has acted as a sentinel guarding online privacy and verified authenticity across the globe while using computers, gadgets and web browsers. But now it seems, like any other product cycle, this one too has reached the platform and soon enough it might require a revamp. A team of three researchers in Israel has claimed their ability to crack 4096-bit RSA encryption keys by listening to internal computer components that produces shrilling noises. Researchers said that they studied the noises produced…

Stanene Could be The New Building Block For Circuit Structures

Pooja Kashyap

Topological insulators by default mean heavy and electron-rich elements however, recent research at sub atomic levels are changing this age-old fact. Researchers have been fascinated with this evolved class of material. According to Wikipedia, A topological insulator is a material with time reversal symmetry and trivial topological order, that behaves as an insulator in its interior but whose surface contains conducting states, meaning that electrons can only move along the surface of the material.

Semiconductors: Graphene Will Be Replacing Silicon In The Chips

Pooja Kashyap

Researchers at the International Technology Roadmap for Semiconductors (ITRS) envision that copper-based relay points in silicon chips would very soon become obsolete. All types of interconnections employed in integrated circuits (ICs) will also cover this redundancy. Graphene, as per scientists, will be the next frontier in computing. Traditional silicon-based transistors and metal interconnects were using materials, which were bulky in the sense that it was affecting the feature-sizes and contact resistance problem. So in order to address this issue, researchers in electrical and computer engineering at the University of California,…

Mathematical Obfuscation: A Trajectory In Cryptographic Research

Pooja Kashyap

Figuring out any computational system’s Achilles’ heel won’t be a trouble-free job as it might be before. Hackers are you listening! Period. Algorithms now are so progressive that deducing future trends is just a matter of few lines of codes. For instance, alogs can calculate which post might pull the maximum readership, on what topic one gets the highest number of tweets or how many times one scans own pic after uploading on facebook (this one’s for datasexuals).
