Debido a la escasa información existente en el país sobre el comportamiento mecánico de las viviendas con estructura de madera, particularmente sobre la capacidad de los muros estructurales; el Instituto Forestal, junto con el apoyo de la División Técnica del Ministerio de Vivienda y Urbanismo, decidió realizar una se…
La presente tesis se centra en el estudio de las envolturas regeneradoras de un reactor de fusion por confinamiento magnetico. Estos componentes criticos para este tipo de reactor, deben proporcionar blindaje a los sistemas magneticos frent al plasma, generar tritio como combustible del reactor e intercambiar calor pa…
The University of Kentucky Center for Applied Energy Research (CAER), Minova USA Inc. and the University of Dundee, Scotland, have collaborated on a project to develop a rapidly deployable system to stabilize shock damaged structures to avoid catastrophic failure. The system comprises a dry-gunned or “gunite” apparatu…
We propose and study a hybrid plasmonic waveguide structure with gain medium. The structure is based on silicon with gain medium to be III-V compound semiconductor, which can be realized by bonding technology.
It has been recently demonstrated that Bi-doped glass optical fibers are a promising active laser medium for 1150-1550 nm. The new results in the field of Bi-doped fiber lasers and optical amplifiers will be considered.
We review photonic and optoelectronic applications of carbon nanotube (CNT) and graphene to such as light emitting, nonlinear, photovoltaic, modulating, and transparently conducting devices. We also present our works on application to short-pulse fiber lasers.
An ultra-short (L=9.5μm) polarization beam splitter (PBS) based on an asymmetrical bent directional coupler is demonstrated experimentally. The measured extinction ratios are about 15dB and 10dB for the TE and TM polarized lights around 1550nm.
A grating-based biosensor via phase detection is stated. The resolution will be 10-7 RIU in the state-of-the-art today. The workspace can be shifted in a large range while the sensor resolution can remain in a high level by only changing the incident angle.
We show that a planar structure, consisting of an ultrathin semiconducting layer topped with a solid nanoscopically perforated metallic film and then a dielectric interference film, can highly absorb (superabsorb) electromagnetic radiation in the entire visible range, and thus can become a platform for high-efficiency…
We investigate the gas absorption properties of porous alumina ceramics with different porosities using gas in scattering media absorption spectroscopy (GASMAS). The gas exchange time for ceramics with 70% porosity is typically within 1 minute.
Blue shift of the bandgap in InGaAsP/InP quantum well structure is demonstrated experimentally. The technique depends upon generation of point defects via plasma induced damage during deposition of sputtered SiO2 followed by rapid thermal annealing.
Edible coating can provide effective protection for fresh fruits. In the present paper we use an edible coating based on whey protein concentrate (WPC) and four different levels of rice bran oil (0, 0.2, 0.4, and 0.6 g/100ml) to maintain the quality of kiwifruit (A. deliciosa). We have tested and compared the followin…
When the segmentation algorithm which considers both the spatial information and color space information is applied to the image of small texture fabric,the segmentation often lacks fidelity.And on the other hand,if the segmentation algorithm which only considers color space information is applied to the image of larg…
A near-infrared wide-band polarization-insensitive absorber is demonstrated. It is composed of two-dimensional titanium disk arrays and a gold plate. The absorption at normal incidence is above 90% in the range of 164.2THz to 345.2 THz.

Aiming at the problem of microstructure control for 42CrMo bar,a mathematical model of phase transformation was proposed on the base of time temperature transformation(TTT) curve with the combination of thermodynamics and kinetics of phase transformation.Meanwhile,the temperature field of cooling process and the micro…
ハイドロタルサイト（HT）の有する陽イオン交換能及び塩基性化合物としての特性を活かしたPb(II)及びCd(II)の固相抽出法について検討を行った．その結果，Pb(II)及びCd(II)はいずれも水溶液のpH 4.0～10.0の範囲で良好にHTに吸着された．吸着実験の結果をLangmuir式で検討したところ，Pb(II)はK＝6.11×105（dm3/mol），b＝4.53×10－4（mol/g），Cd(II)はK＝4.46×105（dm3/mol），b＝1.53×10－4（mol/g）であり，HTがPb(II)及びCd(II)の吸着体として有効であることが示唆された．さらに，Pb(II)及びCd(II)を捕捉したHTを希塩酸に溶…
The Effect of introducing CuInSe2 (CIS) Nanocrystals with the electrolyte on the photocurrent response of DSSCs was investigated showing great enhancement in optical switching and electrical stability of DSSCs by improving the electrolyte’s reduction rate.
Scanning electron microscope(SEM),X-ray diffraction(XRD),X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy(TEM) were used to analyze the morphology,structure and chemical composition of the oxide films formed on stainless steel(SS) 316L in the simulated pressurized water reactor(PWR) primary…
