A climatology of the diurnal cycles of HIRS clear-sky brightness temperatures was developed based on measurements over the period 2002–07. This was done by fitting a Fourier series to monthly gridded brightness temperatures of HIRS channels 1–12. The results show a strong land–sea contrast with stronger diurnal cycles over land, and extending from the surface up to HIRS channel 6 or 5, with reg...

A summary of the results from two research investigations into sensor specification relaxation and image volume registration is presented. The objective of the former study was to develop new processing concepts that would enable the effective deployment of commercially available imaging sensors on low-cost UAV platforms. Within the second study, a range of novel algorithmic designs and process...

-A rotating side-scan sonar system was designed to make time-lapse sonographs of a circular area of the sea floor. To construct the system, the transducers of a commercial side-scan system (frequency 105 kHz; pulse length 0.1 ms; horizontal beam width 1°; vertical beam width 20°; beam depressed 10 ° with respect to horizontal) were mounted 2 m above the sea floor on a vertical shaft that had a ...

Methods A 12 y/o female diagnosed with AIS presented to the clinic, with recent history of 6 degree progression (over 3 months)in thoracic and lumbar curves to be 21 degrees right thoracic and 27 degrees left lumbar, Risser 0, premenarchal, at initiation of treatment. Risk of progression, as calculated using Lonstein-Carlson equation, was greater than 90%. In addition, she had a ScoliScore of 1...

Evolutionary Algorithms (EAs) are common optimization techniques based on the concept of Darwinian evolution. During the search for the global optimum of a search space, a traditional EA will often become trapped in a local optimum. The Scouting-Inspired Evolutionary Algorithms (SEAs) are a recently–introduced family of EAs that use a cross–generational memory mechanism to overcome this problem...

Imprecise manipulation of source code (semi-parsing) is useful for tasks such as robust parsing, error recovery, lexical analysis, and rapid development of parsers for data extraction. An island grammar precisely defines only a subset of a language syntax (islands), while the rest of the syntax (water) is defined imprecisely. Usually water is defined as the negation of islands. Albeit simple, s...

micropolar plasticity provides the capability to carry out post-failure simulations of geo-structures due to microstructural considerations and embedded length scale in its formulation. an essential part of the numerical implementation of a micropolar plasticity model is the integration of the rate constitutive equations. efficiency and robustness of the implementation hinge on the type of inte...

in this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. generally the lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. because of uncertainties and undesired factors, the nominal position and velocity obtained by lambert technique need to be followed in actual flight. ...

Molecular Dynamics (MD) simulations were applied to calculate self-diffusion coefficients (Di ) and heats of adsorption for ethane, propane and n-butane. The simulations were done in temperature range of 300-525 K for various concentrations inside the pores of silicalite type zeolite. The calculated values of self-diffusion coefficients and heats of adsorption resulted from the current wo...
