An exploratory study of the variance of the bidirec(Deschamps et al., 1994) instruments. Also, directional measurements have been made in a variety of laboratory tional reflectance over discontinuous plant canopies indicates that the patterns in variance can be related to the or field settings. However, soon there will be considerable directional imagery available, particularly from the propert...

There has been growing interest to develop a reliable and repeatable method for investigating the mechanical properties of thin films and MEMS materials. In this study, the mechanical response of suspended thin film Al membranes are examined by the Membrane Deflection Experiment (MDE) and nanoindentation. The MDE tests were conducted at temperatures of 2, 27, and 60°C in order to ascertain diff...

In the 1980s, University of Oxford physicist David Deutsch had an insight that would spawn an entirely new goal for physicists. He argued that a computer that manipulates information according to quantum rules rather than classical physics might work much faster than conventional machines. Subsequent studies confirmed that idea, although the rudimentary experiments on quantum computing have so ...

Human placental cells were transformed with wild-type simian virus 40 (SV40) and temperature-sensitive SV40 mutants of the A and B classes. Four criteria for transformation were used: decreased generation time, increased saturation density, increased efficiency of growth on plastic, and ability to overgrow a nontransformed monolayer. Cell lines transformed by tsA mutants lost the transformed ph...

We computationally investigate moth-eye anti-reflective nanostructures imprinted on the endfaces of As2S3 chalcogenide optical fibers. With a goal of maximizing the transmission through the endfaces, we investigate the effect of changing the parameters of the structure, including the height, width, period, shape, and angle-of-incidence. Using these results, we design two different moth-eye stru...

We have developed a novel μ–scale membrane deflection experiment particularly suited for the investigation of submicron thin films and MEMS materials. The experiment cons ists of loading a fixed-fixed membrane with a line load that is applied to the middle of the span with a nanoindenter column. A Mirau microscope-interferometer is positioned below the membrane to observe its response to loadin...

The Knowledge Base Acceleration (KBA) track ran in TREC 2012, 2013, and 2014 as an entitycentric filtering evaluation. This track evaluates systems that filter a time-ordered corpus for documents and slot fills that would change an entity profile in a predefined list of entities. Compared with the 2012 and 2013 evaluations, the 2014 evaluation introduced several refinements, including high-qual...

The control objective of exoskeleton for human performance augmentation is to minimize the human machine interaction force while carrying external loads and following human motion. This paper addresses the dynamics and the interaction force control of a 1-DOF hydraulically actuated joint exoskeleton. A spring with unknown stiffness is used to model the humanmachine interface. A cascade force co...

Dynamic Position Location and Tracking (PL&T) is proposed deploying the integrated approach of zone finding and triangulation using two friendly nodes equipped with Steered Directional Antenna (DA) in Mobile Ad hoc Networks (MANET). This approach allows the system to use only two references instead of a typical 3 references for a straight triangulation. Moreover, the performance of the proposed...
