Abstract: A method of controlling an additive fabrication process includes providing a primary substrate and a test substrate. Polymer test material is extruded onto the test substrate utilizing an extrusion head. The extrusion head is moved relative to the test substrate, and a force required to move the extrusion head relative to the test substrate is measured to thereby generate test data. A part is fabricated by extruding polymer material onto the primary substrate utilizing the extrusion head. The test data is utilized to control at least one process parameter associated with extruding polymer material onto the primary substrate.

Abstract: A sensor system for sensing deformation of a flexible structure includes a beam structure that will be coupled to a surface of the flexible structure having a natural frequency fs, an axial strain ?axialstructure, and a shear strain ?xystructure associated therewith. The beam structure has an axial strain ?axialbeam and a shear strain ?xybeam associated therewith. The beam structure satisfies criteria defined by minimization of a root mean square difference between ?axialstructure and ?axialbeam and minimization of a root mean square difference between ?xystructure and ?xybeam. Fiber optic strain sensors are coupled to and distributed in a spaced-apart fashion along the beam structure. The beam structure is more flexible than the flexible structure such that a combination of the beam structure, the fiber optic sensors, and the flexible structure has a natural frequency fc defined by (0.95)fs?fc?(1.05)fs.

Abstract: The present invention relates to a waveguide-to-microstrip line transition package for superconducting film characterization. The package allows propagation and impedance properties thin-film microwave line superconductor to be characterized at millimeter wave frequencies as a function of frequency. The superconducting film's kinetic inductance can be varied by applying direct current along the ground plane via spring loaded probe. When implemented with a non-superconducting metal housing the present invention is highly suitable for measuring resonators with the quality factor, Q, ranges from 100 to 1×104. Through the use of a housing realized from an appropriate superconducting bulk material or coating the upper end of this range of applicability can be readily extended to >1×106.

Abstract: A base structure is clad and coolant channels are formed through the cladding and into the base structure. A line of tangency relative to the outer clad surface is defined for each point thereon. Linear rows of a metal feedstock are directed towards and deposited on the outer clad surface as a beam of weld energy is directed to the metal feedstock so-deposited. The metal feedstock is the same material as the cladding or one that is weld compatible therewith. A first angle between the metal feedstock so-directed and the line of tangency is maintained in a range of 20-90°. The beam is directed towards a portion of the linear rows such that less than 30% of the cross-sectional area of the beam impinges on a currently-deposited one of the linear rows. A second angle between the beam and the line of tangency is maintained in a range of 5-65°.

Abstract: An antenna system includes a reflector, an offset feed horn and a support platform. The reflector has a reflector surface. The reflector and offset feed horn are attached to the support platform. The offset feed horn transmits RF microwave energy toward the reflector surface. The antenna system further includes a turntable which has a single rotation axis. The turntable rotates about the antenna rotation axis. The support platform is attached to the turntable such that the turntable rotates the support platform. The reflector surface has a perturbed paraboloid geometrical shape that reflects most RF microwave energy along a beam peak pointing direction. The reflector surface reflects RF microwave energy towards the earth's surface in such a manner that the reflected RF microwave energy illuminates a narrow strip of the earth's surface from nadir to a point near the earth's horizon with substantially constant intensity.

Abstract: Method of miles-in-trail passback restrictions for use in air traffic management. Miles-in-trail restrictions can be used as a traffic management initiative when downstream traffic congestion at airports or in sectors is anticipated. To successfully implement the miles-in-trail at airspace fixes or navigational aids, it is desired that restriction values be computed for passing back to upstream facilities at specific boundaries. This method incorporates traffic manager feedback, resulting in significant improvement in guidance. Additional operational considerations required by traffic managers to implement the passback restrictions, namely maximum ground delay and absorbable airborne delay, are used in this method. The method also includes the step of absorbing a small amount of ground and airborne delays which are sufficient to handle the imposed constraint.

Abstract: Episomally transfected primary mesenchymal stem cells (MSC) express a polypeptide consisting of an antigenic polypeptide (e.g., one or more polypeptides) relating to a pathogen (e.g., one or more virus, bacterium, or parasite). The antigenic polypeptide can have the amino acid sequence of a natural polypeptide from the pathogen or an amino acid sequence differing from the natural sequence by one or more conservative amino acid substitutions. Uses and method for treating or preventing infections with episomally transfected primary MSC also are described.

The controller is configured to cause the light source to emit light on the surface, receive the photocurrent from the collector, and determine at least one chemical reaction of the surface based on the received photocurrent.

Abstract: An eye movement-based methodology and assessment tool may be used to quantify many aspects of human dynamic visual processing using a relatively simple and short oculomotor task, noninvasive video-based eye tracking, and validated oculometric analysis techniques. By examining the eye movement responses to a task including a radially-organized appropriately randomized sequence of Rashbass-like step-ramp pursuit-tracking trials, distinct performance measurements may be generated that may be associated with, for example, pursuit initiation (e.g., latency and open-loop pursuit acceleration), steady-state tracking (e.g., gain, catch-up saccade amplitude, and the proportion of the steady-state response consisting of smooth movement), direction tuning (e.g., oblique effect amplitude, horizontal-vertical asymmetry, and direction noise), and speed tuning (e.g., speed responsiveness and noise). This quantitative approach may provide fast and results (e.g.
