Computer Model More Accurately Predicts Flight Delays

Researchers at Binghamton University have devised a new computer model that can more accurately predict delays faster than anything currently in use. The multilevel input layer artificial neural network handles categorical variables with a simple structure to help airlines easily see the relationships between input variables (such as weather) and outputs (flight delays).

Aircraft Arrival Technology Will Reduce Flight Delays

Flight Deck Interval Management (FIM) promises to safely increase the number of airplanes that can land on the same runway at busy airports by more precisely managing the time, or interval, between each aircraft arrival.

Secret Sharing Schemes and Advanced Encryption Standard

There are many secret sharing schemes and variations available to hide and reconstruct the given secret. Shamir’s Secret Sharing Scheme, making use of linear Lagrange interpolation on the dealer-generated polynomial, was used to reconstruct the secret from the stipulated threshold number of participants’ shares. Such a scheme had been widely analyzed by mathematicians and computer scientists for potential weaknesses in the reconstruction of the secret by an external eavesdropper.

SIPHER: Scalable Implementation of Primitives for Homomorphic Encryption

Prior to the Proceed program, the main challenges preventing practical demonstrations and use of Fully Homomorphic Encryption (FHE) were efficiency and scalability. At the start of the Program, the state-of-the-art FHE implementations were both inefficient and not scalable. Work in Scalable Implementation of Primitives for Homomorphic EncRyption (SIPHER) has brought FHE into the realm of practice, bringing several orders of magnitude runtime improvement, and resulting in FHE implementations that can be executed on single and multicore computers (including iPhones). Furthermore, implementation of an FHE hardware accelerator on a Virtex 7 Field Programmable Gate Array (FPGA) can speed up core FHE functions by over three orders of magnitude.

Using Mathematics to Make Computing on Encrypted Data Secure and Practical

In order to make computing on encrypted data more practical to use and more secure from attack, it is necessary to discover, develop, and understand the mathematics on which it is based and the mathematics that can be used to attack it.

Pushbroom Stereo for High-Speed UAV Navigation in Cluttered Environments

Unmanned aerial vehicles (UAVs) rely on an external motion-capture apparatus that gives the vehicles almost perfect state information at high rates. Major challenges in gathering sensing data necessary for flight are the limited payload, computation, and battery life of the vehicles. Lightweight cameras are a good solution, but require computationally efficient machine vision algorithms that can run within the limits of these vehicles.

Modeling and Simulation of an Unmanned Ground Vehicle Power System

Robotic vehicles such as unmanned ground vehicles (UGVs) have multiple sources of power, including batteries, fuel cells, combustion engines, ultracapacitors, and solar cells to allow for extended periods of operation. Fuel-based power sources have a higher specific energy than batteries, which is why most current automobiles are gasoline-powered. Batteries have many other advantages in terms of low noise profile, easy replacement, and direct energy conversion. Solar charging allows for harvesting of natural resources to increase total energy reserves. Mission duration may be maximized using a combination of power systems.

Dual-Node, Short-Depth 4U Chassis

Advantech (Irvine, CA) has launched the 4U, dual-node, short-depth (350mm), industrial chassis ACP-4D00 designed for machine automation applications that require two computers in one piece of equipment. The dual node architecture allows the user to install two half-size slot SBCs in two sub-systems and integrate them in a compact 4U cage. Each ACP-4D00 node supports a PICMG 1.3 or PCI half-size CPU card with computing power up to desktop Core™ i7, 6-slot backplane with maximum 3 PCIe or PCI expansion slots (3 slots are occupied by CPU card) and 250W or 350W high-efficiency 80 Plus power supply.

Currently Advantech offers two PICMG 1.3 CPU cards— PCE-3028 (Intel® Q87), PCE-4128 (Intel® C226), and three PICMG 1.3 backplanes—PCE-3B03-00A1E, PCE-3B06-00A1E, and PCE-3B06-03A1E, for use with ACP-4D00. The system configurations support the latest Intel® 4th generation Core™ i processors, advanced PCIe Gen 3, or legacy PCI expansions.
