The objective of the proposed work (Phases I and II) is to develop uncertainty quantification methodologies and software suitable for use in CFD simulations of aerodynamic flows, ranging from sub-sonic to hypersonic. We will address both pressure and density-based methods, as well as the class of algorithms addressing all-Mach number flows. The software developed here will be based on an existing ...

The overall objective of this proposal (Phases I and II) is to develop a robust and accurate solver for fluid-structure interaction computations capable of addressing multi-body flexible structures as well as rigid body motion. The fluid flow solution will be performed using our unstructured solution-adaptive flow solver TETHYS. We propose to develop a structural solver based on the Galerkin finit ...

Techshot, Inc. proposes continued research and development of an on-orbit cell counter culminating in a deliverable hand-held blood cell counter in the form of a "Microfluidic Multichannel Flow Cytometer". Crew health monitoring, the Human Research Program and research in Fundamental Biology will all benefit from the availability of on-orbit cell counters that can provide immediate and repeated b ...

The proposed "Observation platform for dynamic biomedical and biotechnology experiments using the ISS Light Microscopy Module" consists of a platen sized to fit the stage of NASA's Light Microscopy Module (LMM) on the International Space Station (ISS). At the heart of the innovation is a small hollow microscope slide into which specimens and reagent solutions can be injected by a combination of s ...

The International X-Ray observatory (IXO) is due to be launched in 2021. The core of the instrument is a very large (3.2 meter diameter) Wolter I optic, to be assembled from approximately 13,000 individual elements. Each element will, in turn, be created by 'slumping' glass over a precision mandrel, of which there must be in excess of 700. In addition to the very large size of the mandrels (up t ...

RECENT TECHNICAL ADVANCEMENTS IN THE SEMICONDUCTOR DEVICE AND POWER CONDITIONING TECHNOLOGIES HAVE LED TO SUBSTANTIAL IMPROVEMENTS IN TERMS OF SIZE, WEIGHT, EFFICIENCY AND POWER QUALITY OF THE POWER CONDITIONING EQUIPMENT WHICH IS BEING CONSIDERED FOR SPACE APPLICATIONS. WITH THESE ADVANCEMENTS COMES AN ABUNDANCE OF DESIGN CHOICES AND INCREASED DEGREES OF FREEDOM WITH RESPECT TO POWER SYSTEM CONTR ...

ONE PROMISING APPROACH TO THE DEVELOPMENT OF GENERALIZED MODELS OF COMMUNICATION SYSTEMS IS COMPOSITION OF MODELS FROM COMPONENT MODEL MODULES. IN THIS APPROACH, MODELS OF INDIVIDUAL SYSTEM COMPONENTS ARE DEVELOPED AND SUBSEQUENTLY LINKED INTO A MODEL BY MODEL COMPOSITION SOFTWARE. AN INTEGRATED SOFTWARE ENVIRONMENT SUPPORTS THIS TECHNOLOGY BY MANAGING A MODELBASE OF MODEL MODULES PROVIDING FOR TH ...

A CONSIDERABLE AMOUNT OF R & D WORK HAS BEEN DONE FOR THE WANKEL ROTARY ENGINE APPLICATION TO AUTOMOBILES, PLANES, ETC. RESULTING IN SIGNIFICANT PROGRESS. THE PERFORMANCE, RELIABILITY AND DURABILITY THAT THE WANKEL HAS DEMONSTRATED, HOWEVER, FALLS SHORT OF THE POPULAR DIESEL ENGINE. THE ADIABATIC, TURBOCOMPOUND CONCEPT THAT HAS BEEN DEMONSTRATED FOR THE DIESEL IS THOUGHT TO BE MORE BENEFICIAL TO T ...

CURRENT LIFE-SUPPORT SYSTEMS FOR EXPERIMENTAL ANIMALS CANNOT BE USED FOR DEVELOPMENTAL STUDIES OF ANIMALS IN SPACE. AN INNOVATIVE APPROACH TO THE DESIGN OF AN ANIMAL DEVELOPMENT HABITAT, COMPATIBLE WITH THE MIDDECK LOCKERS OF THE SPACE SHUTTLE, IS BASED ON STUDIES OF NATURALLY-OCCURRING MATERNAL BURROWS OF RODENTS, SURFACE/VOLUME RATIOS OF DIFFERENT HABITAT CONFIGURATIONS, AND ANALYSIS OF PHYSIOLO ...
