Frozen tissue samples represent the state of the art in tissue preservation in many molecular analysis techniques as well as in in membrane analysis using free-fracture techniques. Rapid freezing eliminates the artifact caused by ice crystal formation within the tissues. Ice crystal nucleation and growth occurs between 0?C and -20?C typically. To avoid this damage and minimize destruction of pr ...

The use of eddy-current methods to detect damage in aerospace structures,and to characterize materials is well established, and is a key item to ensure that the risk of structural failures meets the strict damage tolerance requirements established by NASA. This is especially challenging when one considers that common aerospace structures are made from such disparage materials as aluminum, titanium ...

Additive manufacturing lacks efficient, composable physics-based computational frameworks to predict quality and performance for arbitrary geometry, orientation, location and process parameter combinations. A new set of composable computational tools capable of accurately predicting the geometrical accuracy, residual stress and microstructure of the parts made using metal based AM has been develop ...

The proposed innovation is a 3D metal printer, which offers the unique ability to fabricate metal components and tools in space. The proposed system will accomplish this task through the utilization of a two-stage filament melting process whereby a metallic filament is first heated to Curie temperature through induction and then deposited on a build platform where it is fused to the previous layer ...

A robust and reliable wireless communication system capable of surviving the harshness and radiation of space is required for future space missions. Current EVA (Extra Vehicular Activity) communications systems are out dated and in need of an overhaul. Silicon Technologies Inc. (STI) proposes to design a wireless communication ASIC that will include audio DACs, ADCs, and a Dual-band WLAN as well ...

There is high value in simulating the nonlinear dynamics of stowing, deploying, and performance of deployable space structures, especially given the profound limitations of physical testing. Dynamic simulation can reduce the risk of developing new deployable space structures, including solar arrays, by predicting transient motions and loads during stowage, deployment, and mission-related maneuvers ...

PC Krause and Associates is partnering with Purdue University, EleQuant, and GridQuant to create a hybrid modeling capability. The combination of PCKA?s extensive dynamic modeling experience, Purdue?s work in electromechanical systems analysis, and GridQuant and Elequant?s development of the HELM algorithm uniquely positions the team to create this technology. HELM is a novel algorithm that solves ...
