Langley aerospace test highlights, 1985

The role of the Langley Research Center is to perform basic and applied research necessary for the advancement of aeronautics and space flight, to generate new and advanced concepts for the accomplishment of related national goals, and to provide research advice, technological support, and assistance to other NASA installations, other government agencies, and industry. Significant tests which were performed during calendar year 1985 in Langley test facilities, are highlighted. Both the broad range of the research and technology activities at the Langley Research Center and the contributions of this work toward maintaining United States leadership in aeronautics and space research, are illustrated. Other highlights of Langley research and technology for 1985 are described in Research and Technology-1985 Annual Report of the Langley Research Center

Solar Energetic Particles and their Measurement with Space Borne Instruments

The study of our Sun and its various modes of activity is an important area of research in the field of space physics and heliophysics. These active phenomena such as solar flares and Coronal Mass Ejections are associated with energetic particles (protons, electrons, ions, etc.) which are released into our solar system and possess high speed. Some of these energetic particles are likely to reach Earth. In this work, I looked into the various types of solar particle events and their characteristics as well as how these energetic particle properties are measured using space borne instruments. Different instruments using different measurement techniques were also studied, which gives us information about the kind of energetic particles that are measured or detected by these different instruments. A design of a particle telescope, which employs the use of multiple detectors was studied in this work. The telescope had three Si-detectors, a foil material (Kapton polyimide film) and a caesium iodide (CsI) detector. The detector thicknesses were optimised in order to achieve a desired result. Thus in total the design had four detectors and an entrance foil. The thicknesses of the foil material and CsI detector were as well converted into their respective silicon range equivalence in order to optimise the layer thicknesses in the design. Particles are measured at different angles of incidence but for the purpose of this work, I looked at particles penetrating the detectors at 0⁰ and 25⁰ as the limiting values. The results show that the minimum energies a particle needs to penetrate the foil material at 0⁰ and 25⁰ are 4.97 MeV and 5.27 MeV respectively. The effective threshold energy of protons detected in the first detector (D1) is between these values. Furthermore the results give us the information that as the angle of incidence is increasing, the energy also increases steadily. The energy channel resolution for protons stopping in D1, D2 and D3 were 0.386, 0.355 and 0.374 respectively which was close to the desired value (0.4) set as a target of the design

Recommendations for the Classroom Technology and Layout at WPI

The Academic Technology Center (ATC) at WPI replaces the technology in each classroom every five years. The goal of this project, sponsored by the ATC, was to determine how current classroom technology could be improved to enhance the teaching and learning experience. Using interviews and surveys we gathered both qualitative and quantitative information from more than 140 faculty members and 550 students. Based on those findings, we formulated recommendations that include increasing the size of the podium tops and moving the projector screen to maximize board space

Fort Point Channel: Maglev Transit Hub and South Station Expansion Master Plan

This project entails the design of a Magnetic Levitation (or ‘maglev’) transportation hub that interacts with the urban environment of Boston, becoming a modern terminal for this new form of travel as well as a threshold into the heart of the city. Included is the focus on the junction of many scales of transportation (i.e., maglev, train, metro, bus, pedestrian…) currently present at South Station, while stimulating a community with many levels of commercial development and social interventions

The polarimetric and helioseismic imager on solar orbiter

This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter mission (SO/PHI), the first magnetograph and helioseismology instrument to observe the Sun from outside the Sun-Earth line. It is the key instrument meant to address the top-level science question: How does the solar dynamo work and drive connections between the Sun and the heliosphere? SO/PHI will also play an important role in answering the other top-level science questions of Solar Orbiter, as well as hosting the potential of a rich return in further science. SO/PHI measures the Zeeman effect and the Doppler shift in the FeI 617.3nm spectral line. To this end, the instrument carries out narrow-band imaging spectro-polarimetry using a tunable LiNbO_3 Fabry-Perot etalon, while the polarisation modulation is done with liquid crystal variable retarders (LCVRs). The line and the nearby continuum are sampled at six wavelength points and the data are recorded by a 2kx2k CMOS detector. To save valuable telemetry, the raw data are reduced on board, including being inverted under the assumption of a Milne-Eddington atmosphere, although simpler reduction methods are also available on board. SO/PHI is composed of two telescopes; one, the Full Disc Telescope (FDT), covers the full solar disc at all phases of the orbit, while the other, the High Resolution Telescope (HRT), can resolve structures as small as 200km on the Sun at closest perihelion. The high heat load generated through proximity to the Sun is greatly reduced by the multilayer-coated entrance windows to the two telescopes that allow less than 4% of the total sunlight to enter the instrument, most of it in a narrow wavelength band around the chosen spectral line

Development of a design evaluation tool for primary school projects

Thesis (Master)--İzmir Institute of Technology, Architecture, İzmir, 2003Includes bibliographical references (leaves: 113-115)Text in English; Abstract: Turkish and Englishxi, 116 leavesEducation should play an important role in transforming children into productive adults and members of society. School should be the environment of these transformations as an educational milieu in which children collect data through perception. School should also offer a motivating environment while concepts of three-dimensionality, size, proportion and symbolization develop in the child.s mind. Therefore, the spaces in which children are educated have very special importance in their lives.Contemporary schools should have environmental adaptation, be functionally sufficient, aesthetically attractive and structurally appropriate.Since August 18'th 1997, new educational measures have been taking such as renovation of Turkish National Education Program and primary school education which have been extended from five years to eight years. This required capacity increase, restoration of existing school buildings and design of new projects.Development of an evaluation tool for primary school projects has the aim of creating a basis for future primary school projects for both private and national ones
