User data dissemination concepts for earth resources

Domestic data dissemination networks for earth-resources data in the 1985-1995 time frame were evaluated. The following topics were addressed: (1) earth-resources data sources and expected data volumes, (2) future user demand in terms of data volume and timeliness, (3) space-to-space and earth point-to-point transmission link requirements and implementation, (4) preprocessing requirements and implementation, (5) network costs, and (6) technological development to support this implementation. This study was parametric in that the data input (supply) was varied by a factor of about fifteen while the user request (demand) was varied by a factor of about nineteen. Correspondingly, the time from observation to delivery to the user was varied. This parametric evaluation was performed by a computer simulation that was based on network alternatives and resulted in preliminary transmission and preprocessing requirements. The earth-resource data sources considered were: shuttle sorties, synchronous satellites (e.g., SEOS), aircraft, and satellites in polar orbits

User data dissemination concepts for earth resources: Executive summary

The impact of the future capabilities of earth-resources data sensors (both satellite and airborne) and their requirements on the data dissemination network were investigated and optimum ways of configuring this network were determined. The scope of this study was limited to the continental U.S.A. (including Alaska) and to the 1985-1995 time period. Some of the conclusions and recommendations reached were: (1) Data from satellites in sun-synchronous polar orbits (700-920 km) will generate most of the earth-resources data in the specified time period. (2) Data from aircraft and shuttle sorties cannot be readily integrated in a data-dissemination network unless already preprocessed in a digitized form to a standard geometric coordinate system. (3) Data transmission between readout stations and central preprocessing facilities, and between processing facilities and user facilities are most economically performed by domestic communication satellites. (4) The effect of the following factors should be studied: cloud cover, expanded coverage, pricing strategies, multidiscipline missions

Playful Tarot: Adaptations of Tarot In, Through, and Across Games.

The magical practice of divination through tarot emanates from the sacred, ritualistic power of play. Long before tarot accretes esoteric symbolism as a divinatory tool, Italians played it as the parlour game tarrochi. Extending this history, many games implement tarot as a mechanical framework and a source of visual imagery. Yet, not all implementations of tarot are equally successful artistically and spiritually. Ludic tarot is often mechanistic (just another way to think about buffs and stats) or superficially thematic (visual imagery without underlying semiotic content). In this paper, we will unravel the intertwined history of games and tarot, exploring its relationship to other cartomantic practices, including the dark Gnostic “Game of Saturn” decoded by Peter Mark Adams in the Sola-Busca deck, the pragmatically cryptic Lenormand deck, and the divinatory use of standard 52-card playing decks in folk witchcraft. Building upon this historical insight, we will then analyse three related tabletop games as case studies: Chalice (in which tarot generates narratives of a failed Grail quest), Alas Vegas (which resolves conflict and generates narrative through tarot-driven blackjack), and Invisible Sun (which reinvents tarot through the circular Sooth deck driving its magic system). All three of these games weave resonant connections between the imagery and mechanics of cards and fictional gameworlds, thereby investing tarot with an eerie sense of meaningful coincidence or synchronicity. Understanding the techniques that create a more resonant experience of tarot can open the way for a deeper implementation of tarot in game development, as well as enable playful reflection and insight within the magical practice. Specifically, insights into non-digital ludic implementations of tarot can pave the way for richer and more resonant digital tarot applications, building upon and deepening the recent use of tarot in videogames (such as Tanya X. Short’s Cartomancy anthology and Adam Malone’s VR tarot)

Development of scenarios for land cover, population density, impervious cover, and conservation in New Hampshire, 2010–2100

Future changes in ecosystem services will depend heavily on changes in land cover and land use, which, in turn, are shaped by human activities. Given the challenges of predicting long-term changes in human behaviors and activities, scenarios provide a framework for simulating the long-term consequences of land-cover change on ecosystem function. As input for process-based models of terrestrial and aquatic ecosystem function, we developed scenarios for land cover, population density, and impervious cover for the state of New Hampshire for 2020–2100. Key drivers of change were identified through information gathered from six sources: historical trends, existing plans relating to New Hampshire’s land-cover future, surveys, existing population scenarios, key informant interviews with diverse stakeholders, and input from subject-matter experts. Scenarios were developed in parallel with information gathering, with details added iteratively as new questions emerged. The final scenarios span a continuum from spatially dispersed development with a low value placed on ecosystem services (Backyard Amenities) to concentrated development with a high value placed on ecosystem services (the Community Amenities family). The Community family includes two population scenarios (Large Community and Small Community), to be combined with two scenarios for land cover (Protection of Wildlands and Promotion of Local Food), producing combinations that bring the total number of scenarios to six. Between Backyard Amenities and Community Amenities is a scenario based on linear extrapolations of current trends (Linear Trends). Custom models were used to simulate decadal change in land cover, population density, and impervious cover. We present raster maps and proportion of impervious cover for HUC10 watersheds under each scenario and discuss the trade-offs of our translation and modeling approach within the context of contemporary scenario projects

Justice for Rodney King

May 1992 letter from three Howard University School of Law students to President George H.W. Bush advocating that the United States Department of Justice invoke the Petite Policy to initiate a criminal action against the Los Angeles Police Department police officers responsible for brutally beating Rodney King despite the fact that these offers had been acquitted in a California state court. The letter, which was read in front of the White House by Thomas Mitchell to hundreds of people who had gathered to urge the federal government to take action, sets forth a clear legal basis to permit the Justice Department to prosecute those responsible for the trampling of Rodney King\u27s civil rights

Paper Session I-C - Multifunctional Air Revitalization Systems

The end goal in developing air revitalization systems is improved performance and enhanced capability to enable long-duration interplanetary life support. The evolution of current and near-term techniques is the most likely path to achieve future systems in which consumables are regenerated to effect weight and cost savings. Regenerative solid amine sorbents are now in use in the Space Shuttle Extended Duration Orbiter (EDO); currently, the solid amine performs only the carbon dioxide (CO2) removal function. Testing was conducted on solid amines to better understand the behavior during CO2 adsorption and the influences of trace contaminant gases. Tests were conducted, beginning hi 1991, using Thermogravimetric Analysis (TGA) system and on a sorbent column linked to a mass spectrometer and a gas chromatograph to ascertain the ability of the solid amine to remove CO2 and trace contaminants. Solid amine adsorption and desorption test data were obtained for trace contaminants representing corrosive and reactive compounds typical of space cabin atmospheres. Test results show that the solid amine has the ability to regeneratively remove trace contaminants, although some highly corrosive gases bond irreversibly. The TGA system proved to be a rapid, versatile method to screen trace contaminants for effects on solid amine; the column system provided more realistic conditions and analysis of off-gas products. Both analysis tools have provided initial capability to assess regenerative air revitalization techniques that may then be combined to create a multifunctional, closed-loop atmosphere purification system

Constructing Confidence Intervals For Flexible Budget Cost Estimates

A multiple-cost flexible budget can be constructed using either the Aggregate Cost Analysis Method or the Component Flexible Budget Method.  This paper derives and illustrates the use of a confidence interval formula for an annual cost estimate that is developed by summing 12 monthly flexible budget estimates

Disposal of Household Wastewater in Soils of High Stone Content (1981-1983)

Four experimental filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm below the soil surface. The fragipan restricts downward movement of water and is the designlimitingfeature. The four filter fields were: 1. A standard filter field, 76 cm deep. The bottom of the trench was in the fragipan. 2. A modified standard filter field, 30 cm deep. The bottom of the trench was above the fragipan. 3. A modified pressure filter field, 40 cm deep. The bottom of the trench was above the fragipan. In addition, a pressure-distribution system was used to insure uniform distribution of effluent in the trench. Inadvertently, this field was installed in a different soil, and the results cannot be compared directly with the other three. 4. Another modified pressure filter field with the bottom of the trench only 6 cm below the soil surface. Observation of these systems confirms that placing filter fields higher in the soil above the hydraulically limiting horizon results in improved hydraulic performance. The presence of the fragipan amplified the adverse effects attributable to climatic stress. The seepage beds which are higher in the soil profile are able to handle the effluent load and climate load with less danger of surfacing
