Station-keeping guidance

The station-keeping guidance system is described, which is designed to automatically keep one orbiting vehicle within a prescribed zone fixed with respect to another orbiting vehicle. The active vehicle, i.e. the one performing the station-keeping maneuvers, is referred to as the shuttle. The other passive orbiting vehicle is denoted as the workshop. The passive vehicle is assumed to be in a low-eccentricity near-earth orbit. The primary navigation sensor considered is a gimballed tracking radar located on board the shuttle. It provides data on relative range and range rate between the two vehicles. Also measured are the shaft and trunnion axes gimbal angles. An inertial measurement unit (IMU) is provided on board the orbiter. The IMU is used at all times to provide an attitude reference for the vehicle. The IMU accelerometers are used periodically to monitor the velocity-correction burns applied to the shuttle during the station-keeping mode. The guidance system is capable of station-keeping the shuttle in any arbitrary position with respect to the workshop by periodically applying velocity-correction pulses to the shuttle

Economic Analysis of Using Soybean Meal as a Mushroom Growing Substrate

Mushrooms have been grown commercially on many different substrates for years, usually agricultural by-products such as straw or stover. Increased popularity for specialty mushrooms with consumers has led to increased production and great demand for economic substrates. Oyster mushrooms are easier to grow relative to other types of mushrooms and their production has increased dramatically in recent years. This study examines the economic feasibility of using soybean hulls as a primary substrate for oyster mushrooms, replacing traditional wheat straw. The study uses a cost-benefit analysis to determine an optimal substrate based on yield and the number of crops harvested per year. The study shows that soybean hulls, combined with corn gluten or soybean meal increases yield 4.5 times, which more than offsets for higher costs for soybean hulls. The use of soybean substrate also allows a producer to raise about four more crops per year, which in turn uses fixed resources more efficiently and increases profitability.Oyster, Mushrooms, Substrate, Soybean, Hulls, Meal, Economic, Feasibility, Crop Production/Industries,

Geometric Scaling and QCD Dynamics in DIS

DIS data from HERA show a striking regularity as \sigma^{\gamma^* p} is a function of the ratio \tau=Q^2/Q_s^2(x) only. The scaling function shows a break at \tau ~ 1, which has been taken as an indication for saturation. However, besides saturation also the transition between dominance of k_t-ordered (DGLAP) and k_t-non-ordered (BFKL) evolution contributes to a break around this value of \tau, as well as the suppression for small Q^2 due to finite quark masses and confinement. In this paper we use a dipole cascade model based on Mueller's dipole model, which also includes energy conservation and pomeron mergins, to investigate the contributions of these different effects to the scaling behaviour. As a result we predict that the scaling function for \tau 1 GeV^2 become available. We also investigate the scaling properties of the charm contribution and the impact parameter dependence of the saturation scale.Comment: references added, figures 2, 7 and 8 updated v3: reference added, some misprints correcte

Net solar generation potential from urban rooftops in Los Angeles

Rooftops provide accessible locations for solar energy installations. While rooftop solar arrays can offset in-building electricity needs, they may also stress electric grid operations. Here we present an analysis of net electricity generation potential from distributed rooftop solar in Los Angeles. We integrate spatial and temporal data for property-level electricity demands, rooftop solar generation potential, and grid capacity constraints to estimate the potential for solar to meet on-site demands and supply net exports to the electric grid. In the study area with 1.2 million parcels, rooftop solar could meet 7200 Gigawatt Hours (GWh) of on-site building demands (~29% of demand). Overall potential net generation is negative, meaning buildings use more electricity than they can produce. Yet, cumulative net export potential from solar to grid circuits is 16,400 GWh. Current policies that regulate solar array interconnection to the grid result in unutilized solar power output of 1700 MW. Lower-income and at-risk communities in LA have greater potential for exporting net solar generation to the grid. This potential should be recognized through investments and policy innovations. The method demonstrates the need for considering time-dependent calculations of net solar potential and offers a template for distributed renewable energy planning in cities

But Where Shall Wisdom be Found? \u3ci\u3eThe Lord of the Rings\u3c/i\u3e and the Wisdom Literature of the Hebrew Bible

Wisdom literature is a kind of writing that evolved in the ancient world as soon as mankind began to explore the meaning of life and sought understanding and insight. The Hebrew Bible contains three canonical books that scholars consistently identify as Wisdom Literature – Proverbs, Job and Ecclesiastes. This paper explores the connections (common content, shared plot elements and structure, similar characters with similar struggles and perspectives, and even themes and outlooks), between this body of wisdom and Tolkien’s The Lord of the Rings. Specifically, this essay will define wisdom literature, and then compare wisdom literature to Tolkien’s work in three ways: generally – looking at shared overall characteristics individually – looking at Proverbs, Job and Ecclesiastes separately and comparing each to The Lord of the Rings cumulatively – proposing that the three wisdom books, when taken together, offer a complex and nuanced overall theme, and demonstrating that this theme is also present in The Lord of the Rings

People Just Don\u27t Seem to be Listening : A Case for a Functional Approach to Reputation Management

This paper focuses on the growing study of corporate reputation management and the potential benefits of focusing management attention on building, sustaining, and defending the corporate brand\u27s reputation. Specifically, the purpose of the paper is to provide a logical justification for major corporations to add the role of chief reputation officer to their organizational structures in order to properly manage this significant intangible asset. Secondary research of print and electronic news media coverage was conducted to document a case history of the reputation crisis and ultimate demise of Big Five accounting firm Andersen (more commonly known as Arthur Andersen). The case history was developed to provide a significant example of the negative consequences of ignoring corporate reputation management. Because the study of corporate reputation management is relatively new, definitions of corporate reputation and reputation management are also presented to introduce the basic tenets of reputation management science. These definitions are drawn from the related disciplines of reputation management, corporate communications, brand management, corporate branding, identity, image, public relations, and integrated marketing communication. A review of multidisciplinary literature indicated a lack of consistency in the definitions that may be hindering the widespread adoption of formalized corporate reputation management. Secondary research on the concept of chief reputation officer revealed two academics and one practitioner coming from the reputation management perspective who have previously argued for the adoption of the role. However, the arguments lacked a comprehensive list of responsibilities, clear and tangible support such as short case histories, and fully developed justification and rationale. To rectify the deficiencies of these existing arguments, the paper offers an executive summary for corporate senior management and boards of directors to justify the chief reputation officer by detailing the role\u27s breadth and depth of responsibilities and providing a comprehensive list of the substantial benefits created by a good corporate brand reputation. Further support for the chief reputation officer role and formalized reputation management is provided through analysis of unplanned communications involved during the Andersen reputation crisis. The effect of negative unplanned communications from stakeholders and negative brand associations that spilled over from the accounting industry\u27s reputation commons added credence to the theory that poor reputations feed on themselves. An assessment of the research and related case histories indicated that management of corporate reputation involves complex internal and external factors that are well beyond the purview of the public relations and corporate communications functions. It also indicated that reputation is affected by multidimensional relationships between corporate brands and their stakeholders that can best be managed by a full-time senior executive who is singularly focused on building, sustaining, and defending the corporate brand\u27s reputation
