International Conference on Infrared and Millimeter Waves

作者： Hotsumi Iwasaki Makoto Okano Nozomu Komatsubara Madoka Nakamura Atsuto Moriwaki Harumi Sato Shinichi Watanabe Keio University Kanagawa Japan Kobe University Kobe Japan

We report on a drawing-ratio dependence of the refractive index difference between the two optic axes (Δn) of poly lactic acid films in terahertz frequency range. We found that Δη can be controlled in a range of 0-0.04 by changing the drawing ratio. The result shows that we can design a terahertz wave plate with arbitral retardation, which will be useful for establishing polymer-based terahertz optical component with low cost and easy implementation in mass production.

Non Line of Sight propagation is an important reason effecting to the positioning accuracy of Ultrawide Bandwidth system. It's difficult to model and distinguish NLOS signal, as the characteristics of NLOS signal are closely related to the environment. Therefore, the NLOS identification may be modeled a one-class classification problem. This method only uses LOS signal as the target class instance to determine the one-class classification interface and realize the detection of NLOS signals. The experimental results show that, without the NLOS signals, the detection performance of one-classclassification using only LOS signals is similar to support vector machine algorithm which need two kinds of signals.

A (u × v × w, k, λa, λc) optical orthogonal signature pattern code (3-D OOC) is a family C of (u × v × w) (0, 1)-matrices of Hamming weight k that satisfies two correlation properties. In this paper, new classes of three-dimensional (3-D) optical orthogonal signature pattern codes for applications to optical code-division multiple access (OCDMA) networks are proposed. The new classes are based in the two dimensional optical orthogonal signature pattern codes.

3D printing technology provides an affordable method of prototyping antennas. To design antennas with this technology it is necessary to characterize the materials used for printing precisely in terms of their permittivity and conductivity. Two major groups of materials for antenna design are dielectric and conductive materials. In this paper, we consider measurement of dielectric constants of three types of polylactic acid (PLA) plastic materials that can be used for 3D printing of antennas and other radio frequency (RF) devices.

A number of half-salen aluminum complexes bearing unsymmetrical [ONN]-type ligands were prepared from tridentate dinaphthalene-imine derivatives. These complexes were characterized by H-1 and C-13 NMR spectroscopy, elemental analysis and single crystal X-ray diffraction analysis. These complexes were employed for rac-lactide and L-lactide polymerization. Upon activation with isopropanol, complex (S)-B-6 (R-1 = R-2 = R-4 = H;R-3 = F) showed the highest activity (a monomer conversion of 94.6%) amid these aluminum complexes for the ring-opening polymerization of L-lactide;and complex (S)-B-2 (R-1 = R-2 = R-3 = H;R-4 = Bu-t) showed the highest stereoselectivity for the ring-opening polymerization of rac-lactide, obtaining a polylactide (PLA) with a Pm of 0.69. The polymerization kinetics utilizing (S)-B-6 as a catalyst were researched in detail. The data on the polymerization kinetics revealed that the rate of polymerization was first-order with respect to the monomer and the catalyst. There was a linear relationship between the L-lactide conversion and the number-average molecular weight of PLA.

Thermal Pretreatment of Kudzu Biomass (Pueraria lobata) as Filler in Cost-Effective PLA Biocomposite Fabrication Process

This article aims on the fabrication of cost-effective polylactic acid (PLA) biocomposites using kudzu biomass derivatives as new filler. In this way, it has been realized that pretreatment of the filler was an essential requirement. We demonstrated thermal pyrolysis process that targeted to extraction and isolation of all extractable and unnecessary compounds such as intracellular water and bio-oil from the biomass. Also, to further improve the compatibility of the filler with PLA, noncatalytic thermal esterification reactions of kudzu after thermal pyrolysis (called char) were carried out as second pretreatment stage in the presence of phthalic anhydride. Kudzu derivatives obtained from either first or second pretreatment reactions were melt-blended with PLA in various rates. The blends were then compression molded into dumbbell specimens. Physicomechanical properties of the prepared biocomposites were evaluated using several analytical techniques. It was found that biocomposites containing treated biomass had higher values of physicomechanical properties than untreated ones. The final rate of filler to PLA with acceptable properties was set up to 50%. Obviously, the cost of PLA can be reduced using higher rates of low-cost filler on a finished-product basis. Extracted valuable compounds from biomass via thermal pyrolysis could be another benefit of the process. POLYM. ENG. SCI., 55:340-348, 2015. (c) 2014 Society of Plastics Engineers

Novel crossbar antifuse for high-density user programmable logic array (PLA) is presented. Circuit area reduction and routability increase of PLA are achieved by crossbar architecture based on pure-CMOS antifuse adjacently integrated into low-voltage and high-speed logic transistors. In addition, since our crossbar antifuse technique can be fabricated according to the standard design rule of advanced CMOS process, it is easy to implement our PLA as a user-customizable embedded logic in SoC. The logic density of our test chip in 65 nm process technology is 1835 lookup-tables (LUTs)/mm 2 , which is larger than any previous reports.

Labeling salient region accurately in video with cluttered background and complex motion condition is still a challenging work. In this paper, an efficient and low complexity spatiotemporal consistency optimization model, and a video saliency framework using the spatiotemporal consistency are proposed. We derive the superpixel-level spatial and temporal saliency value by integrating three spatial saliency features and two temporal saliency features respectively. After optimizing the spatial and temporal saliency map respectively using spatiotemporal consistency optimization model, the spatial and temporal saliency map are fused and enhanced by spatiotemporal consistency optimization. Finally, pixel-level salient regions are generated by graph-cuts algorithm. Experimental results on two challenging benchmark video datasets demonstrate the superiority and robustness of proposed spatiotemporal consistency optimization model and video saliency detection framework over state-of-the-art methods.

Nowadays, some synthetic polymers have been replaced by biodegradable polymers in order to avoid environmental contamination. Among these biodegradables polymers, aliphatic polyesters such as polylactic acid (PLA) and polycaprolactone (PCL) have been widely used. In the present study, solvent-casting films of PLA, PCL and polymer blends with and without compatibilizer (PLA grafted with maleic anhydride) were prepared. The thermal diffusivity (a) of each sample was obtained by using the open photoacoustic cell technique. Morphology and thermal properties were determined by using scanning electron microscopy, transmission electron microscopy and differential scanning calorimetry (DSC), respectively. The blends showed lower thermal diffusivity compared to pure polymers. However, when the compatibilizer was used, the highest value of thermal diffusivity was obtained. Also, cold crystallization with the highest value of enthalpy of fusion was observed for the compatibilized sample, which was revealed by DSC. To our knowledge, this is the first time that the thermal diffusivity of these biodegradable polymer blends is reported.
