Approximately 70% of sentinel events in medical care are related to communication mishaps, and despite regular and frequent occurrence, an even higher percentage (80%) of severe medical errors are related to miscommunication during handoffs (i.e., the transferring of information, responsibility, and authority for patient care from one provider to another). The TiER1 team proposes to address challe ...

Micro-RDC has developed portable radiation effects test structures that scale to new process nodes.These structures will enable the investigation of the effects of radiation on the new technology from the material processing level as well as the circuit level.Fabricating the chosen structures and the refinement of software to extract the model parameters will be completed in this effort.A suite of ...

In this STTR Phase I program, Structured Materials Industries, Inc. (SMI) and Arizona State University (ASU) will develop a SiGeSn based light emitter device technology on Si, which will be a key ingredient for Si-based integrated photonics applications, such as in lab-on-a-chip integrated chemical and biological spectrometers for landers, astronaut health monitoring, front-end and back-end for re ...

Swarm robotics is one of the key enabling technologies for significantly extending mankind's reach beyond the Earth's surface. However, when bringing theory to practice, challenging problems related to the coordination and control of these swarms quickly arise. Vecna Robotics proposes a collaboration with MIT to extend existing autonomy behaviors and test platforms to address a class of pl ...

Reducing the allowable concentration of carbon dioxide (CO2) in spacecraft is a critical need for NASA. The system now used on the International Space Station (ISS) is the carbon dioxide removal assembly (CDRA). While it has performed well on the ISS, managers have concluded that using the device to reach the new ppCO2 limit of 2.0 mm Hg is not practical and a new method is needed.In this projec ...

NASA has been investigating morphing aircraft for multi-mission capabilities and performance improvements in existing fixed-wing aircraft. In addition, the design of aeroelastic aircraft that can control the structural flexibility to their advantage, is an open area of research and development. In spite of the plethora of work on morphing aircraft and long slender wings, the goal of fielding such ...

Niobium alloy (C-103) reaction control system (RCS) chambers have been used on numerous NASA programs. However at elevated temperatures, the strength of C-103 decreases significantly. Higher strength niobium alloys have been developed, but these alloys lack the formability of C-103. Recently, Additive Manufacture (AM) of niobium and C-103 has been demonstrated using powder bed electron beam me ...

Opterus Research and Development, Inc. proposes to develop and validate multi-scale thin-ply High Strain Composites (HSCs) constitutive modeling tools for incorporation into commercial finite element analysis codes. The constitutive models will capture the time-temperature-load-deformation viscoelastic characteristics common to HSCs as well as the yielding or permanent deformation associated with ...

The landing surface damage and liberation of debris particles caused by rocket plume impingement flow during spacecraft propulsive landing on unprepared surfaces of Moon, Mars, and other celestial bodies poses a high risk for robotic and human exploration activities. Simply determining whether the plume induced loads exceed the bedrock bearing capacity threshold is not sufficient. An integrated m ...

Spacecraft propulsive landings on unprepared regolith present in extra-terrestrial environments pose a high risk for space exploration missions. Plume/regolith interaction results in (1) the liberation of dust and debris particles that may collide with the landing vehicle and (2) craters whose shape itself can influence vehicle dynamics. To investigate such gas-granular interactions for large-scal ...
