Estimating Time Available For Sensor Fusion Exception Handling, Robin R. Murphy, Erika Rogers

Computer Science and Software Engineering

In previous work, we have developed a generate, test, and debug methodology for detecting, classifying, and responding to sensing failures in autonomous and semi-autonomous mobile robots. An important issue has arisen from these efforts: how much time is there available to classify the cause of the failure and determine an alternative sensing strategy before the robot mission must be terminated?

In this paper, we consider the impact of time for teleoperation applications where a remote robot attempts to autonomously maintain sensing in the presence of failures yet has the option to contact the local for further assistance. Time limits are …

Tunable Picosecond Infrared Laser System Based On Parametric Amplification In Ktp With A Ti:Sapphire Amplifier, D. E. Gragson, D. S. Alavi, G. L. Richmond

Chemistry and Biochemistry

A picosecond laser system that will generate high-power tunable IR pulses with bandwidths suitable for spectroscopic applications is discussed. The system is based on white-light continuum generation in ethylene glycol and optical parametric amplification in potassium titanyl phosphate. The nonlinear-optical processes are driven by a regeneratively amplified Ti:sapphire laser that produces 1.7-ps pulses at a repetition rate of 1 kHz. Energies as high as 40 and 12 µJ have been achieved over the signal (1.02–1.16-µm) and idler (2.6–3.7-µm) tuning ranges, respectively. The IR beam temporal and spatial characteristics are also presented.

Market Power And Performance: A Cross-Industry Analysis Of Manufacturers And Retailers, Kusum L. Ailawadi, Norm Borin, Paul W. Farris

Marketing

Two recent studies of manufacturer and retailer profitability in the food industry have raised questions about whether the widely cited, but empirically untested, shift of power from manufacturers to retailers has really occurred. Has the marketing community been operating under a misconception or are these studies flawed? This paper uses more complete measures of exercised and potential market power and a broader sample of industries and retail classes to address this critical question. Not only do our measures have strong theoretical grounding in the industrial organization, finance and accounting literature, they incorporate in them the impact of actions that have …

Irrigation Water Conservation - Benefits And Tradeoffs, Charles M. Burt

BioResource and Agricultural Engineering

Water conservation must be examined within the context of a water balance for a zone of specified boundaries. On-farm conservation may not result in basin conservation, and may actually damage water supplies within the basin, especially if groundwater supplies dwindle. Conservation must also take place with recognition of water rights, and therefore concepts such as Irrigation Efficiency and Irrigation Sagacity must be well understood. Because of the diversity of hydrology, there is no single menu of water management improvements which are applicable in all cases. In the future, more emphasis will be placed upon improving crop yields with a given …

Three-Phase Intersection Points In Monolayers, John P. Hagen, Harden M. Mcconnell

Chemistry and Biochemistry

Some phospholipid/dihydrocholesterol Langmuir monolayers form coexisting liquid phases. Gas domains form at the interface between the phospholipid-rich and dihydrocholesterol-rich liquid phases when these monolayers undergo expansion to low surface pressure. Analysis of the domain shapes thus formed yields the relative line tensions of the gas/phospholipid, gas/dihydrocholesterol, and phospholipid/dihydrocholesterol phase interfaces.

Essential Water Delivery Policies For Modern On-Farm Irrigation Management, Charles M. Burt

BioResource and Agricultural Engineering

Successful on‐farm irrigation scheduling requires that water delivery projects adopt a service concept, and that water deliveries be made with a high degree of reliability. An arranged delivery schedule and seasonal volumetric allocations are additional requirements. Until these conditions are met, attempts to implement modem on‐farm irrigation scheduling techniques to maximize water use efficiency and yields will be only partially successful.

Guidelines For Establishing Irrigation Scheduling Policies, Charles M. Burt

BioResource and Agricultural Engineering

Successful on-farm irrigation scheduling requires that water delivery projects adopt a service concept, and that water deliveries be made with a high degree of reliability.

Remanence Measurements On Individual Magnetotactic Bacteria Using A Pulsed Magnetic Field, Ietje Penninga, Hendrik De Waard, Bruce M. Moskowitz, Dennis A. Bazylinski, Richard B. Frankel

Physics

We describe pulsed-magnetic-field remanence measurements of individual, killed, undisrupted cells of three different types of magnetotactic bacteria. The measurement technique involved the observation of aligned, individual magnetotactic bacteria with a light microscope as they were subjected to magnetic pulses of increasing amplitude. We show that for MM cells, the hysteresis loop is square, with the coercive field variable from cell to cell. This is consistent with just two magnetization states for the single chain of magnetite particles. For MR and MMP cells, the hysteresis loops are not square, indicating that there are several different magnetization states, and that individual cells …

Controlled Biomineralization Of Magnetite (Fe3O4) And Greigite (Fe3S4) In A Magnetotactic Bacterium, Dennis A. Bazylinski, Richard B. Frankel, Brigid R. Heywood, Stephen Mann, John W. King, Percy L. Donaghay, Alfred K. Hanson

Physics

A slowly moving, rod-shaped magnetotactic bacterium was found in relatively large numbers at and below the oxic-anoxic transition zone of a semianaerobic estuarine basin. Unlike all magnetotactic bacteria described to date, cells of this organism produce single-magnetic-domain particles of an iron oxide, magnetite (Fe₃O₄), and an iron sulfide, greigite (Fe₃O₄), within their magnetosomes. The crystals had different morphologies, being arrowhead or tooth shaped for the magnetite particles and roughly rectangular for the greigite particles, and were coorganized within the same chain(s) in the same cell with their long axes along the chain …
