This paper describes the degradation properties of bisphenol A type epoxy with a carboxyl-terminated butadiene-acrylonitrile (CTBN) and nano-clay. For evaluation of degradation by radiation, gamma rays of 500 kGy, 1000 kGy, and 1500 kGy were used to irradiate the samples at the dose rate of 8 kGy/hr. The degradation properties of the gamma-ray irradiated samples were measured using a thermogravimetric analyzer (TGA). In the TGA experiment, as the absorption dose increased and the heating rate decreased, the thermogravimetry-derivative thermo gravimetry (TG-DTG) curves of the samples rapidly decreased. As the absorption dose increased, the activation energy of the epoxy decreased sharply, but that of the samples to which clay had been added tended to decrease initially and then increase at 1500 kGy.
This paper summarizes a sensor fusion approach for rolling-element bearing prognostics developed in the DARPA engine system prognosis (ESP) program. Bearings are critical components of an aircraft engine, so detecting...

This paper presents a novel game-like advertising system called GameSense, which is driven by the compelling contents of online images. Given a Web page which typically contains images, GameSense is able to select suitable images to create online in-image games for advertising. The contextually relevant ads (i.e., product logos) are embedded at appropriate positions within the online games. The ads are selected based on not only textual relevance but also visual content similarity. The game is able to provide viewers rich experience and thus promote the embedded ads to provide more effective advertising. Copyright is held by the author/owner(s).
We present a novel reduction method of port-Hamiltonian systems by a renormalization group. The reduced system is suitable for a fast numerical calculation in a mesoscopic scale. Especially, we aim at the development ...

This paper introduces a development process of a manipulator that is installed to a mobile robot system and used to detect explosive ordnance and dispose it. Based on system requirements, its boundary conditions are analyzed and the minimum driving ranges and RPMs of each joint are calculated. To choose the optimum actuators including reduction ratio's of the gearbox, the advanced Straete et al.'s normalization method is used after conducting dynamic analysis. Two kinds of dynamic analyses are executed to confirm the result, one is MATlab's SimMechanics and the other one is PRO-Engineer's Mechanism. Finally, structural analysis is conducted to verify the robustness of the designed system.
