As NASA’s Director of Space Technology Programs, Michael Gazarik contributes to the development of technology that can be applied to NASA’s exploration systems, space operations, and science missions. Gazarik integrates and tracks all investments...

Hybrid Diagnosis Engine (HyDE) is a general framework for stochastic and hybrid model-bused diagnosis that offers flexibility to the diagnosis application designer. The HyDE architecture supports the use of multiple modeling paradigms at the component and system level. Several...

As communication and networking technologies advance, networks will become highly complex and heterogeneous, interconnecting different network domains. There is a need to provide user authentication and data protection in order to...

The Sensory Ego-Sphere (SES) is a short-term memory for a robot in the form of an egocentric, tessellated, spherical, sensory-motor map of the robot’s locale. Visual attention enables fast alignment of overlapping images without warping or position optimization, since an attentional...

Crewmembers returning from long-duration space flight face significant challenges due to the microgravity-induced inappropriate adaptations in balance/sensorimotor function. The Neuroscience Laboratory at JSC is developing a method based on stochastic...

The memristor is the fourth fundamental passive electronic device in addition to the resistor, capacitor, and inductor. By integrating with complementary metal oxide semiconductor (CMOS) devices, memristors show promise for development of revolutionary new nanoelectronic computing architectures with...

Historically, the military has used special- purpose Global Positioning System (GPS) radios for radio navigation. This has the disadvantage of locking users into fixed technology solutions designed to meet a fixed set of requirements. Software Defined Radios (SDR) have the...

Realistic combinations of ceramics and/or semiconductors have been developed that simultaneously achieve high hardness (>40 GPa) and toughness (>400 MPa*m1/2). To achieve this goal, there were three primary objectives: (1) the development of physically base...

The Spoken Language Communication and Translation System for Tactical Use (TRANSTAC) is developing and fielding freeform, two-way translation systems that enable speakers of different languages to communicate with one another in real-world tactical situations without an...

Sparse data models, where data is assumed to be well represented as a linear combination of a few elements from a dictionary, have gained considerable attention in recent years, and their use has led to state-of-the-art results in many signal and image processing tasks. Sparse modeling calls for constructing a succinct...

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity. The electrochemical formate production and the biological carbon dioxide fixation...

The first gateway to the detection of potentially cancerous tumors or lesions often occurs during the physical exam at the doctor's office, which is performed through touch. As one might imagine, conclusions made from such a test could be very subjective, depending on the physician's experience...

A tiny prototype robot that functions like a living creature could be safely used to pinpoint diseases within the human body. Called ‘Cyberplasm’, it will combine advanced microelectronics with latest research in biomimicry (technology inspired by nature). The aim is for Cyberplasm to have an...
