This paper discusses a nonlinear spectrum processing approach to speech enhancement. The technique incorporates a "soft' nonlinearity which suppresses low—level noise components while passing higher—level speech components. Although the algorithm is an extension of the spectral subtraction concept, the soft nonlinearity provides less distortion of(More)
Enzymatically degradable semi-interpenetrating polymer networks (edsIPNs) were explored for their biocompatibility and ability to promote new scleral tissue growth, as a means of reinforcing the posterior wall of the eye. The edsIPNs comprised thermoresponsive poly(N-isopropylacrylamide-co-acrylic acid), customizable peptide crosslinkers cleavable by matrix(More)
There has been generally little attention paid to the utilization of biomaterials as an anti-myopia treatment. The purpose of this study was to investigate whether polymeric hydrogels, either implanted or injected adjacent to the outer scleral surface, slow ocular elongation. White Leghorn (Gallus gallus domesticus) chicks were used at 2 weeks of age.(More)
In this study, we have developed conductive tips with high aspect ratio and good sharpness by scanning electron beam induced deposition (SEBID) method. The structure and morphology of modified conductive tips were performed by analytical transmission electron microscopy (TEM) methods. Atomic force microscope (AFM), scanning Kelvin probe microscopy (SKPM)(More)

To truly make automation economical, there needs to be a shift in robotic performance: from highly specific at one task to general-purpose across many tasks. Unfortunately, such additional functionality is not cost-effective without a sacrifice in performance. In the case of robotics, it is a sacrifice in accuracy. This paper first investigates an industry(More)
This paper illustrates the design and implementation of a robotic software system based on robot-human interactions, which increases the applications of low-cost, inaccurate robots such as Baxter. The first four parts of the paper discuss the motivation, market & industry, IP strategy and system workflow. Then the paper explains a specific technical(More)
This project concerns the development of a system which allows tasks to be taught to a robotic manipulator using learning by demonstration. A subsystem calculates the accuracy required of the manipulator and determines which portion of the learned task it is able to perform. Therefore, the system can avoid performing tasks that require accuracy beyond the(More)
My project will be to design a RC helicopter that can be controlled with gestures via a control glove. The helicopter, including all mechanical parts, battery, and IR receiver, will come as-is out of box so the only thing that needs to be designed is the controller. The controller will be a in the form of a control glove and will contain different sensors(More)
