UAG R-268

This study was supported by the Bureau of Land Management through interagency agreement with the National Oceanic and Atmospheric Administration under which a multi-year program responding to need of petroleum development of the Alaskan continental shelf is managed by the Outer Continental Shelf Environmental Assessment Program (OCSEAP) Office. Drawings were done by Debbie Cocci a and Jim Burton. The idea of this project arose during a conversation between George Edwardson, Jr., and one of the Principal Investigators. Rachael Craig and Edna MacLean helped in initiating the project and Mrs. Molly Pederson of the North Slope Borough Inupiaq Language Commission obtained some of the narratives and interviews and provided translations. Teri McClung assisted with transcription of interviews and editing. Finally, the hospitality of the family of Kenneth Toovak during the translation process is gratefully acknowledged.The objective of this program was to extend the data base on ice hazards along the Beaufort Sea coast of Alaska backward in time by using the knowledge and understanding of ice and weather conditions of the local residents. Information for this pilot project was obtained through direct interviews with residents, or from narratives supplied by them. The results of these procedures were evaluated to provide a basis for improving similar efforts in future. Observations of particular interest obtained from these interviews and narratives include (1 ) a description of a major motion of the landfast ice off Harrison Bay in late February, (2) a description of the formation of ice push ridges and ride-up at Cape Halkett during break up, (3) reports of whales traveling inshore of Cross Island during the fall migration and of whales being taken by crews from the Prudhoe Bay area at that time of year, and 4) descriptions of conditions in the nearshore area during summer. In addition information of historical and cultural interest was obtained.Supported by NOAA Contract 03-5-022-55, Task No. 6ABSTRACT -- ACKNOWLEDGEMENTS -- TABLE OF CONTENTS : INTRODUCTION ; PROCEDURES ; RESULTS ; DISCUSSION AND EVALUATION -- APPENDIX I -- APPENDIX II -- APPENDIX II

A component-based model and language for wireless sensor network applications

Wireless sensor networks are often used by experts in many different fields to gather data pertinent to their work. Although their expertise may not include software engineering, these users are expected to produce low-level software for a concurrent, real-time and resource-constrained computing environment. In this paper, we introduce a component-based model for wireless sensor network applications and a language, Insense, for supporting the model. An application is modelled as a composition of interacting components and the application model is preserved in the Insense implementation where active components communicate via typed channels. The primary design criteria for Insense include: to abstract over low-level concerns for ease of programming; to permit worst-case space and time usage of programs to be determinable; to support the fractal composition of components whilst eliminating implicit dependencies between them; and, to facilitate the construction of low footprint programs suitable for resource-constrained devices. This paper presents an overview of the component model and Insense, and demonstrates how they meet the above criteria.Preprin

Secondary techniques for increasing fault coverage of fault detection test sequences for asynchronous sequential networks

The generation of fault detection sequences for asynchronous sequential networks is considered here. Several techniques exist for the generation of fault detection sequences on combinational and clocked sequential networks. Although these techniques provide closed solutions for combinational and clocked networks, they meet with much less success when used as strategies on asynchronous networks. It is presently assumed that the general asynchronous problem defies closed solution. For this reason, a secondary procedure is presented here to facilitate increased fault coverage by a given fault detection test sequence. This procedure is successful on all types of logic networks but is, perhaps, most useful in the asynchronous case since this is the problem on which other techniques fail. The secondary procedure has been designed to improve the fault coverage accomplished by any fault detection sequence regardless of the origin of the sequence. The increased coverage is accomplished by a minimum amount of additional internal hardware and/or a minimum of additional package outputs. The procedure presented here will function as part of an overall digital fault detection system, which will be composed of: 1) a compatible digital logic simulator, 2) a set of fault detection sequence generators, 3) secondary procedures for increasing fault coverage, 4) procedures to allow for diagnosis to a variable level. This research is directed at presenting a complete solution to the problems involved with developing secondary procedures for increasing the fault coverage of fault detection sequences --Abstract, pages ii-iii

The reaction of urea with primary alkyl bromides

The reactions between urea and the primary alkyl bromides from 1-bromobutane to 1-bromooctane were investigated. The effect of concentration, temperature, and solvents on the yield was determined. Second order reaction rate constants at temperature of 80°, 100°, and 132°C were calculated from the data for yield. The yield is defined as the percent of bromine from the alkyl bromide titrated as bromide ion. The results indicate that the reactions of the primary alkyl bromides with urea are similar; the reaction being of the second order and the ex. tent of reaction being approximately the same for each alkyl bromide for corresponding reaction conditions. At a temperature of 132°C, yields of approximately 90% or greater are obtainable for reaction periods of two hours or more. Further chemical and kinetic investigation is required in order to define the mechanism of reaction with greater certainty

Species composition and pasture productivity of Bermudagrass-fesue-legume combinations for yearling beef steers

A beef-steer (Bos sp.) grazing experiment was conducted on a Typic Hapludalfs soil. The 1.2 ha pastures were (1) Midland (Cynodon dactylon (L.) Pers.) + fescue (Festuca arundinacea Schreb.)(25) + N, (2) Midland + fescue(25) + legumes, (3) Midland + fescue(50) + legumes, (4) fescue + legumes, (5) 1/3 annual grasses + N and 2/3 fescue + legumes in separate pastures (0.4 and 0.8 ha), (6) common (C. dactylon var. dactylon) + fescue(25) + legumes, and (7) orchardgrass (Dactylis glomerata L.) + ladino clover (Trifolium repens L.). Legumes refer to overseedings of ladino clover, red clover (T. pratense L.) and lespedeza (Lespedeza striata (Thunb.) H & A). The 25 and 50 refer to the distances in cm between fescue rows at seeding. Annual grasses were a sorghum-sudangrass hybrid (Sorghum bicolor (L.) Moench) seeded in mid-May and rye (Secale cereale L.)-ryegrass (Lolium multiflorum L.) seeded in early September each year. Annual grass pastures received 134 kg N ha-1 year-1, Midland + fescue(25) + N pastures received 290 kg N ha-1 year-1. Pastures were grazed continuously. Forage growth and consumption were estimated by the cage and strip method. Yearling beef steers weighing 230 kg in the spring grazed 131 to 168 days and were weighed at 21-day intervals. Forage consumption was 62% or more of forage growth, which ranged from 6786 to 14232 kg/ha. Crude protein was well above the minimum requirement for growing steers. Neutral- and acid-detergent fiber ranged from 63 to 67%, and from 39 to 43%, respectively. Stocking rates were between 3.2 and 7.7 steer/ha. Average daily gains (ADG) were greatest on Orchardgrass + clover (869 g/day) and ranged from 478 to 821 g/day for the other treatments. Productivity ranged between 591 animal grazing days/ha for Common + fescue(25.) + legumes and 1537 for Midland + fescue(25), and ranged from 605 to 833 for the other pastures. Daily forage dry matter (DM) intake was 6.3 to 15.3 kg/steer, with conversion efficiencies of about 12 to 20 kg DM/kg gain. Beef production-was 630, 474, 510, 597, 431, 392, and 545 kg/ha for treatments 1-7, respectively. The Species Composition Index (SCI) was evaluated in relation to the-effects of year, season, grazing pressure, forage quality, precipitation, and air temperature on forage growth and consumption, and animal performance. It was compared to the traditional classification variable \u27treatment\u27 to describe the seven different pasture combinations. When treatment was entered into the model to explain total variation in forge growth and consumption, ADG, and beef production, R2\u27s of 0.15, 0.32, 0.34, and 0.36 were obtained respectively; when SCI was used, they were 0.36, 0.51, 0.53, and 0.56
