Langley Atmospheric Information Retrieval System (LAIRS): System description and user's guide

This document presents the user's guide, system description, and mathematical specifications for the Langley Atmospheric Information Retrieval System (LAIRS). It also includes a description of an optimal procedure for operational use of LAIRS. The primary objective of the LAIRS Program is to make it possible to obtain accurate estimates of atmospheric pressure, density, temperature, and winds along Shuttle reentry trajectories for use in postflight data reduction

Put Down that Book! Producing Poetry to Center Students as Organic Intellectuals

Schools are often sites of hegemony, where certain knowledge and voices are prioritized over others. This hierarchy frequently discounts students as producers of their own knowledge, ignoring the wisdom gleaned from their lived experiences, diverse racial and ethnic backgrounds, and cultural communities. While the study of literature inside a high school English classroom can be fruitful for students to acquire empathy and perspective, it is only effective when it is equitable. Educators must implement diverse representation in narratives, characters, authors and texts to represent students whose identities exist at the margins. Positioning work by Women of Color in the classroom is central to inviting students, especially the historically underrepresented and under researched experiences of Black and brown girls in education, to engage with organic intellectualism, and see themselves as producers of knowledge. This field project offers a curriculum of three lesson plans which elevate the work of Aurora Levins Morales and bell hooks, and eight selected poets (who are also women of color), to model organic intellectualism and its power in personal poetry. These lessons culminate in original, student created poetry, with opportunities for classmates to witness and cherish each others’ voices and wisdom

Wind-tunnel free-flight investigation of a supersonic persistence fighter

Wind-tunnel free-flight tests have been conducted in the Langley 30- by 60-Foot Wind Tunnel to examine the high-angle-of-attack stability and control characteristics and control law design of a supersonic persistence fighter (SSPF) at 1 g flight conditions. In addition to conventional control surfaces, the SSPF incorporated deflectable wingtips (tiperons) and pitch and yaw thrust vectoring. A direct eigenstructure assignment technique was used to design control laws to provide good flying characteristics well into the poststall angle-of-attack region. Free-flight tests indicated that it was possible to blend effectively conventional and unconventional control surfaces to achieve good flying characteristics well into the poststall angle-of-attack region

DNA-based memory device and method of reading and writing same

The present invention is directed to a memory device having very high storage density capability. In general, the memory device includes an array of individual memory cells which store information that is assigned a value based on the molecular contents of the memory cell. In a preferred embodiment, the molecules utilized for storing information in the memory cells may be single-strand polynucleotides, for instance single-strand oligonucleotides of between about 5 and about 20 monomer units. The present invention is also directed to methods and systems useful for writing and reading the molecular-based memory devices. In particular, the devices may be written and read via modified atomic force microscopy processes
