Prototype Genomics-Based Keyed-Hash Message Authentication Code Protocol

This is targeted for applications without an available public key infrastructure. Goddard Space Flight Center, Greenbelt, Maryland Cryptography and molecular biology share certain aspects and operations that allow for a set of unified principles to be applied to problems in either venue. A DNA-inspired hash code system is presented that utilizes concepts from molecular biology. It is a keyed-Hash Message Authentication Code (HMAC) capable of being used in secure mobile ad-hoc networks. It is targeted for applications without an available public key infrastructure. Ad-hoc does not mean the users are completely unknown to each other. They could be part of a military unit, police, emergency workers, mobile vendors, or any collection of users in a common geographical area that wish to communicate in a region lacking a PKI (Public Key Infrastructure).

Station Spacewalk

Ames Research Center, Moffett Field, California The Station Spacewalk game enables players to virtually conduct NASA repair work on the International Space Station, including jobs critical to help power up the space station so it can continue to operate. Players are provided with a limited quantity of oxygen during which they must complete extravehicular activities (EVAs) and return to the airlock before the air supply runs out.

Are we moving toward pilotless airliners?

This week's Question: NASA has worked with industry to help create the Synthetic Vision System (SVS), a virtual reality display system for cockpits. The SVS uses 3D to provide pilots with intuitive means of understanding their flying environment, including graphical displays of terrain and hazards. In coming months, Universal Avionics, an avionics manufacturer, will release a product called InSight, which blends larger displays, higher-resolution 3-D synthetic vision, and new icon-based command-and-control architecture. Some say that synthetic vision developments, along with other emerging aviation technologies like touch-screen steering and voice recognition, could lead to a day when airliners fly themselves. What do you think? Are we moving toward pilotless airliners?>

Product of the Month: December 2014

COMSOL, Burlington, MA, announced COMSOL Multiphysics® software version 5.0 that features product updates, three new add-on products, and the new Application Builder. The Application Builder lets users build applications for use by engineering and manufacturing departments, expanding accessibility to the expertise and to simulation solutions. The Application Builder enables engineers to make available an easy-to-use application based on their COMSOL Multiphysics model. Included with the Windows® operating system version of COMSOL Multiphysics® 5.0, the Application Builder provides tools needed to build and run simulation apps. Any COMSOL Multiphysics model can be turned into an application with its own interface using the tools provided with the Application Builder desktop environment. Other features include the Form Editor, in which the user interface layout can be designed, and the Methods Editor for implementing customized commands. The new version also includes a Ray Optics Module, Design Module, and LiveLinkTM for Revit®.

Thermal Imaging’s Pocket-Sized Potential

Let’s say you’re a prospective buyer touring an older home that you suspect has some weatherization issues. What if you could verify your hunch by literally seeing cold air seeping under doors or cooling walls where insulation is missing? And what if you could do this on the spot using a smartphone?
