Designing for 3D Printing

3D printing has progressed over the past decade to include multimaterial fabrication, enabling production of powerful, functional objects. While many advances have been made, it still has been difficult for non-programmers to create objects made of many materials (or mixtures of materials) without a more user-friendly interface.

Making VR a NASA Reality

NASA researchers want to prove that a virtual reality headset like the Oculus Rift is not just a toy. Josh Kinne, a deputy project manager at NASA Langley Research Center, sees a future role for virtual and augmented reality in the agency’s research and development, CAD design, and data visualization efforts.

IoT Security Toolkit

Icon Labs (West Des Moines, IA) recently announced its Floodgate IoT Security Toolkit. The solution enables IoT edge devices to be easily and securely integrated with IoT cloud platforms, including Verizon’s ThingSpace IoT Cloud Platform, and provides security management for remote IoT devices from a single user interface. The new Icon Labs Floodgate IoT Security Toolkit provides connectivity to the cloud platform over a secure communication link for both normal device operation and for security management. The solution includes critical security countermeasures to protect the device from attack, intrusion detection to identify when the device is being attacked, and security management to respond to attacks.

Lunar Thin Section Particle Identification and Analysis Algorithm

Particle shape is a very important property in many fields of research, and with many practical, diverse, and commercially important applications including pharmaceuticals, civil engineering, metallurgy, health, and food processing. Many of the methods used to evaluate the shapes of solid particles employ a plane section through the particles. This mode may be termed Plane of Section. Plane of Section abstracts three-dimensional (3D) objects to two dimensions (2D).

Libibvpp

Libibvpp provides a C++ wrapper API to the libibverbs library. Libibverbs is the OpenIB library that provides the Verbs API for programming Infiniband hardware. It is written in C and provides a C API. Because the API is in C, it is up to the library user to do explicit resource management for the objects created through the API.

Analytical Methodology to Predict the Radiometric Emissivity of a Parabolic Mesh Reflector

The demands for high-sensitivity and high-resolution radiometry have recently led the science community to examine the use of large deployable mesh reflectors, which have heretofore only been used in telecommunications applications.

Detection and Characterization of Recurring Slope Lineae

Recurring Slope Lineae (RSL) are low-albedo features that appear and disappear seasonally on Martian slopes. They provide distinct surface markers that are thought to result from the activity of subsurface water. Reliable characterizations of RSL activity are needed to test this hypothesis. RSL are of high scientific interest, and could inform future mission planning priorities beyond sample return.
