Abstract: Described herein is a new design for a combat vehicle, such as a battle tank, that includes enhanced armor plating overhead of the passengers inside the vehicle. The enhanced armor may include thicker plating within a turret that is arranged over where one or more passengers are seated within a turret basket. In some respects, the plated region of the turret may also protect rear features such as an autoloader from frontal attacks. The armored turret region may have a thickness of at least 500 mm or may have a thickness that extends an entire height of the turret. One or more occupants of the combat vehicle may be seated within a turret basket beneath the turret, such that they are arranged beneath the armored turret region when seated and better protected from overhead attacks.

Abstract: The present disclosure provides new approaches in developing templated polymer-based chemical receptors. At least some embodiments of the invention use a stimuli-responsive polymer [e.g., poly-Nisopropylacrylamide (pNIPAM)] as a polymer backbone with the incorporation of functional monomers (for analyte recognition). In at least some embodiments of the invention, vinylferrocene may be used as a redox-active label for electrochemical transduction.

Abstract: A method and apparatus for producing boron nitride nanotubes and continuous boron nitride nanotube yarn or tapes is provided. The apparatus includes rotating reaction tubes that allow for continuous chemical vapor deposition of boron nitride nanotubes. The rotation of the reaction tubes allows the boron nitride nanotubes to be spun into yarns or made into tapes, without post process or external rotation or spinning of the gathered nanotubes. Boron nitride nanotube yarns or tapes of great length can be produced as a result, thereby providing industry with a readily useable format for this type of material. Dopants such as carbon can be added to engineer the band gap of the nanotubes. Catalysts may be formed outside or inside the reactor.

The apparatus and method are configured to eliminate gaps in image detection for fault-proof collection of imagery for an underwater survey. In some examples, long baseline (LBL) is utilized for mapping detected images to a location. In some examples, ultra-short baseline (USBL) is utilized for mapping detected images to a location. The apparatus and method are configured to utilize a simultaneous localization and mapping (SLAM) approach.

Abstract: This disclosure is generally directed to a microstrip phased array antenna with a switch line phase shifter to obtain steerable beam pattern. In an embodiment, the microstrip phased array antenna includes a plurality microstrip lines disposed/patterned on a substrate to form a relatively compact phase shifter network that can switchably introduce phase shifts into an RF signal. In particular, each phase shifter of the phase shifter network may be formed from a number of equal-length RF lines that extend from a common point and “loop” to form substantially circular paths. The common point from which each of the RF lines extend may include a VIA to couple to an antenna device. A plurality of switches, e.g., PIN diodes, may be disposed along the RF lines to switchably extend the overall length of each of the phase shifters, and more particularly each transmission line, to selectively introduce a target phase shift.

Abstract: Techniques are provided for implementing an end-fire synthetic aperture sonar system. A methodology implementing the techniques according to an embodiment includes generating a plurality of matched-filtered signals (pings) based on correlations of a transmitted sonar signal with a plurality of reflected or scattered returns of the transmitted signal received from a hydrophone, the reflected or scattered returns associated with a plurality of locations of the hydrophone relative to a location of a transmitter. The method further includes generating a coarse estimate of the locations of the hydrophone based on incoherent cross correlations of the pings, and generating a refined estimate of the locations of the hydrophone based on the coarse estimate and further based on coherent cross correlations of the pings. The method further includes performing delay-and-sum beamforming to combine the pings, the beamforming employing time delays based on the estimated locations of the hydrophone.

Abstract: Techniques for EMD-based signal de-noising are disclosed that use statistical characteristics of IMFs to identify information-carrying IMFs for the purposes of partially reconstructing the identified relevant IMFs into a de-noised signal. The present disclosure has identified that the statistical characteristics of IMFs with noise tend to follow a generalized Gaussian distribution (GGD) versus only a Gaussian or Laplace distribution. Accordingly, a framework for relevant IMF selection is disclosed that includes, in part, performing a null hypothesis test against a distribution of each IMF derived from the use of a generalized probability density function (PDF). IMFs that contribute more noise than signal may thus be identified through the null hypothesis test. Conversely, the aspects and embodiments disclosed herein enable the determination of which IMFs have a contribution of more signal than noise.

Abstract: A three step synthesis of the 8,12-dihydro-4H-dibenzo[cd,mn]pyren-3a2-ylium cation (triangulenium cation) is effected by cascade cyclization of a tetra-benzyl alcohol precursor in triflic acid solution. This cation is easily observed by NMR and optical spectroscopy. Quenching of the cation into basic solutions or by hydride transfer from triethylsilane provides access to stable dihydro and tetrahydro[3]triangulenes. This route makes several [3]triangulene precursors more readily available for development of new applications in the field of molecular electronics.
