Acoustic manipulation of sound with soft material-based actuators
No full textThis thesis describes a unique parabolic acoustic manipulator with an inflatable structure, which has high gain and directivity. We created a morphable elastomeric reflecting surface with a diameter of 14 cm (6 in). Applying vacuum deforms the device into a concave structure, which provides directional amplification of incoming acoustic waves. In addition, the author characterized the impedance of the soft material employed in the acoustic reflector, Ecoflex 00-10, in an impedance tube. Ecoflex 00-10 has a measured reflection coefficient of approximately 0.9 at frequencies ranging from 500 Hz to 5000 Hz. This new characterization suggests this class of silicone-based elastomers is capable of advanced morphable devices to manipulate sound. Simulations also demonstrate that the soft reflecting surface is capable of transformation into a set of desired parabolic shapes between an initial planar geometry (neutral position) and a configuration with maximum curvature. With an applied vacuum, the membrane reaches its maximum deformation limited by the aluminum housing. At this stage of actuation, experimental results show the deformed membrane has similar gain and directionality (polar response) as rigid parabolic reflectors. This type of system might find future uses for adjustable parabolic microphones and long-range communication devices.M.S.Includes bibliographical referencesby Yanjun Wan
Bioinspired preparation of polydopamin microcapsule for multienzyme system construction
No full textInspired by the structural organization of mitochondria and the bioadhesive principle, a simple and versatile approach to construct a multienzyme system is developed. More specifically, the multienzyme system is composed of a polydopamine (PDA) microcapsule scaffold and three spatially separated enzymes. The PDA microcapsules are prepared through the rapid, spontaneous self-polymerization of dopamine on the surface of CaCO3 microparticle template, followed by dissolution of the template using EDTA. The wall thickness of the microcapsules can be tuned by the dopamine concentration in an aqueous solution. The three enzymes are respectively immobilized through physical encapsulation in the lumen, in situ entrapment within the wall and chemical attachment on the out surface under extremely mild conditions. As an example, a multienzyme system, containing α-amylase, β-amylase and glucosidase, was constructed to convert starch into isomaltooligosaccharide, and the multienzyme system displays higher catalytic activity and enhanced operational stability. The method developed in this study will establish a powerful platform for the facile construction of multienzyme cascade systems. © 2011 The Royal Society of Chemistry.Lei Zhang, Jiafu Shi, Zhongyi Jiang, Yanjun Jiang, Shizhang Qiao, Jian Li, Rui Wang, Ruijie Meng, Yuanyuan Zhu and Yang Zhen
Discovering patterns in a survey of secondary injuries due to agricultural assistive technology
No full textThe research is motivated by the need for hazard assessment in agriculture field. A small and highly-imbalanced dataset, in which negative instances heavily outnumber positive instances, is derived from a survey of secondary injuries induced by implementation of agriculture assistive technology which assists farmers with injuries or disabilities to continue farm-related work. Three data mining approaches are applied to the imbalanced dataset in order to discover patterns contributing to secondary injuries.
All of patterns discovered by the three approaches are compared according to three evaluation measurements: support, confidence and lift, and potentially most interesting patterns are found. Compared to graphical exploratory analysis which figures out causative factors by evaluating the single effects of attributes on the occurrence of secondary injuries, decision tree algorithm and subgroup discovery algorithms are able to find combinational factors by evaluating the interactive effects of attributes on the occurrence of secondary injuries. Graphical exploratory analysis is able to find patterns with highest support and subgroup discovery algorithms are good at finding high lift patterns.
In addition, the experimental analysis of applying subgroup discovery to our secondary injury dataset demonstrates subgroup discovery method's capability of dealing with imbalanced datasets. Therefore, identifying risk factors contributing to secondary injuries, as well as providing a useful alternative method (subgroup discovery) of dealing with small and highly-imbalanced datasets are important outcomes of this thesis.</p
AudioEar: Single-View Ear Reconstruction for Personalized Spatial Audio
No full textAbstract
We introduce AudioEar3D, a high-quality 3D ear dataset consisting of 112 point cloud ear scans with RGB images, to benchmark the ear reconstruction task. We further collect a 2D ear dataset composed of 2,000 images, each one with manual annotation of occlusion and 55 landmarks, named AudioEar2D. To our knowledge, both datasets have the largest scale and best quality of their kinds for public use.

No full textNitrate and phosphate supplementation to increase toxin production by the marine dinoflagellate Alexandrium tamarense
No full textAlexandrium tamarense toxins have great value in biotechnology research as well as important in connection with shellfish poisoning. The influence of nitrate or nitrate and phosphate supplementation on cell biomass and toxin content were investigated in batch cultures. When cultures at low nitrate (88.2 mu M NaNO3) Were supplemented with 793.8 mu M NaNO3 at day 10 the cell density and cellular toxin contents were increased by 6-29% and 20-76%, respectively, compared with controls, and maximal values were 43,600 cells/ml (day 38) and 0.91 pg/cell (day 31). Supplementation with nitrate at day 14 or with nitrate and phosphate at day 10/14 to the cultures did not increase the cell density compared with the non-supplemented middle nitrate or high phosphate (108 mu M NaH2PO4) cultures, respectively, but increased the cellular toxin contents by an average of 52%. The results showed that supplementation with nitrate or with nitrate and phosphate at different growth phases of the cultures increased toxin yield by an average of 46%. Supplementation with nitrate at selected times to maintain continuous low level of nitrate might contribute to the effective increase of toxin yield of A. tamarense. (c) 2005 Elsevier Ltd.
