The recently developed Spring Back Reflector has low stiffness in the deployed configuration. A general method of stiffening this type of reflector without changing its folding properties is presented. The stiffening is achieved by adding a conical skirt around the edge of the dish; this skirt snaps elastically when the dish is folded. The paper concludes that it is possible to design spring ba...

in the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. experimental investigation has been carried out in cylindrical column with and without twisted tapes. twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different sta...

According to the deformation and movement requirements of the FAST reflector, a multipurpose analysis, including the load-bearing behavior, deformation, construction costs of the reflector supporting structure and its model, is presented in this paper. The advantages and disadvantages of steel and aluminum alloy structures are also discussed and compared through detailed design calculations und...

We have successfully prepared anodized alumina membrane distributed Bragg reflector (DBR) using electrochemical anodization method. The transmission peak of this distributed Bragg reflector could be easily and effectively modulated to cover almost any wavelength range of the whole visible spectrum by adjusting anodization temperature.

We have proposed and fabricated a new mid-infrared reflector using the guided-mode resonance (GMR). The GMR reflector consists of subwavelength Ge grating on GaAs substrate with a low-refractive-index SiOx layer in between. With a total thickness of about 2 μm, a near-100% reflectivity at 8 μm has been obtained both theoretically and experimentally.

A millimeter wave antenna measurement system is presented. The frequencies of operation are around 100 GHz and 300 GHz (W/J Bands). The facility is a single reflector compact range system. Design tasks deal with the serrated reflector and the corresponding millimeter wave instrumentation design.

background: the aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age. materials and methods : twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angels were estimated by this algor...

専攻科電子工学専攻におけるPBL教育について 皆本佳計*、横山隆志*、 * 新居浜工業高等専門学校 電気情報工学科 新居浜工業高等専門学校紀要(特定論文) 第 51 巻 pp1-4 平成 27 年 1 月 PBLとは、Project Based Learning(プロジェクト・ベースト・ラーニング)の略称であり、日本語では 「プロジェクト型学習」や「問題解決型授業」などと訳されることが多い。PBLは、 課題の解決を目的と し、それをチームの力によって課題を解決することや受講者の自主性・自律性を重んじることなどで、従 来の教育手法では育成が難しかった問題解決能力を効率的に育成することが可能な教育手法して注目を集 めている。専攻科電子工学専攻では、技術者に必要な倫理観とシステムデザイン能力を身につけ、ものづ くりを通して社会貢献できる人材を育成することを目標としている。これを実現するため...

conclusions lv twist, torsion and untwist and also rate of them are significantly impaired in dcm and this impairment is well-related to lv global systolic and diastolic dysfunction. vvi is a new noninvasive technique that can be used to evaluate lv torsional parameters. results lv twist value (5.54 ± 1.94° in dcm vs. 11.5 ± 2.45° in control group) and also lv torsion (0.71 ± 0.28°/cm in dcm vs...
