A Feasibility Study for a Remotely Controlled, Low-power- consumption Scanning Electron Microscope Suitable for Space Applications

Experiments and instruments for operation in and on small satellites are constrained by the volume, weight, power, and ruggedness requirements of the satellite design and structure. It is anticipated that increasing numbers of laboratory style experiments will be performed in space. An application of current interest is the in-space observation of material surfaces exposed to the space environment. One such instrument for possible small satellite flight operational use, is a scanning electron microscope (SEM). The design factors and parameters of such an SEM, as well as the trade-offs and instrument limitations, will be discussed. The electronic control and image relay requirements will be presented. This study shows that by choosing the proper design for an SEM, this instrument could be a valuable and useful tool to be flown on a small satellite

Design of a Low-Cost Data Communications/R.F. System for use with Low Earth Orbiting Store and Forward Satellites

The functional requirements and system overview for a low cost data communications system for small satellite use are presented. Tradeoffs of system parameters will be discussed such as: cost, transmission speed, power consumption, spectrum usage, and system complexity. Link calculations at 137 MHz, with transmission speeds of 9600 BPS, monopole antennas, and a 50kHz bandwidth show that adequate signal margins can be obtained with 2 Watts of R.F. power for most conditions. Use of low cost, amateur or commercial type radio equipment requires only minor modifications, and creates small reliability and performance risks

The documentation and preservation of art-in-architecture of Michigan: The section of fine arts projects

The Section of Fine Arts’ Art-in-Architecture program created public and permanent cultural artifacts that expressed and recorded American beliefs, values, and stories for future generations. Many of these artworks have been saved. Sadly, others have been neglected, mistreated, or forgotten. This project focuses on The Section’s post office art installations in Michigan. The Section of Fine Arts, one of FDR’s New Deal programs of the Depression era, operated under the auspices of the Treasury Department. The program utilized symbols of the common man to tie together a nation’s scattered and often isolated communities, to promote a common heritage and purpose, and to relate the past to the present while giving hope for the future. The documentation of these art-in-architecture projects is essential as is the need to conserve them. Although challenging, the effort is vital to insure the survival of these records of an important and distinctive American chapter

thesisThe goal of this study was to investigate the relationship between mood states and conversational argument behavior. Specifically, relationships among vigorous, angry, and depressive mood states and specific agreement or disagreement prone argument behaviors is analyzed. Stephen Toulmin’s argument model, concepts of field argument, and substantial and analytic argument types provided the theoretical background for this study, as Toulmin’s model of argument and related features outline how arguments unfold. An observational study of married couples revealed significant correlations between vigor with agreement acknowledgement, anger with objections, and depression with responses. Seventy-two individuals composing 36 romantic couples engaged in problem-solving interactions in their homes regarding conflict topics that they nominated. Correlations between mood state and argument behavior suggest that mood plays an important part as people negotiate conversational arguments. Specifically, mood and argument behavior appear to have a strong connection during social interaction. This study also revealed biological sex differences in how argument behaviors associate with mood. Moreover, links between positive and negative mood differ according to argument forms of agreement and disagreement. Finally, this study points toward future research exploring a wide range of mood states and argument behavior and possible causal connections between the two phenomena
