Abstract:
A low-cost robotic shake table and method for operating the same is disclosed. The shake table includes a chassis having a pedestal slidably coupled to two linear shafts. The shake table also includes a motion system having a stepper motor, a transmission, and a motor driver, with the stepper motor coupled to the pedestal through the transmission. The shake table includes a perception system having a camera, an accelerometer coupled to the pedestal, and a plurality of fiducial markers coupled to the pedestal, and a microcontroller communicatively coupled to the motor driver and the perception system. The microcontroller is configured to receive an input motion data, produce a set of translational velocities based upon the input motion data, and convert the set of translational velocities into a control signal that will cause the stepper motor to move the pedestal along the linear shafts according to the translational velocities.
Abstract:
A method for temporally and spatially aligning a laser-based x-ray source and maintaining alignment is disclosed. A pump laser beam, which interacts with a plasma source to create an electron beam, is aligned with the electron beam. A scattering laser beam is overlapped with the pump laser beam at an intersection point. The pump laser beam and scattering laser beam alignments are monitored and adjusted to maintain optimal alignment during operation of the laser-based x-ray source.
Abstract:
This invention relates to a method and device for collecting a Mycobacterium complex species, such Mycobacterium tuberculosis (MTB) from the oral cavities of particularly children and infants. A device is provided which has a distal end and an operative end portion manufactured from a parent polymer which has been functionalised with a chemical compound having an affinity to the Mycobacterium complex species to collect same such that the presence thereof in the sample can be detected. The invention further extends to a method of preparing biological material obtained from such collected sample.
Abstract:
Recombinant mycobacterial strains which overproduce essential biosynthetic enzymes of pathogenic mycobateria are provided. These strains overproduce enzymes involved in the synthesis and incorporation of D-alanine into mycobacterial peptidoglycan, the backbone of the mycobacterial cell wall. These overproducing strains may be used as reference strains in in vitro screening methods to identify antimycobacterial agents.

Abstract:
The present invention relates to the fabrication of a boron carbide/boron semiconductor devices. The results suggest that with respect to the approximately 2 eV band gap pure boron material, 0.9 eV band gap boron carbide (B5C) acts as a p-type material. Both boron and boron carbide (B5C) thin films were fabricated from single source borane cage molecules using plasma enhanced chemical vapor deposition (PECVD). Epitaxial growth does not appear to be a requirement. We have doped boron carbide grown by plasma enhanced chemical vapor deposition. The source gas closo-1,2-dicarbadecaborane (orthocarborane) was used to grow the boron carbide while nickelocene (Ni(C5H5)2) was used to introduce nickel into the growing film. The doping of nickel transformed a B5C material p-type relative to lightly doped n-type silicon to an n-type material. Both p-n heterojunction diodes and n-p heterojunction diodes with n- and p-type Si null1,1,1null respectively. With sufficient partial pressures of nickelocene in the plasma reactor diodes with characteristic tunnel diode behavior can be successfully fabricated.
