Ellipsoidal bounds for static response of framed structures against interactive uncertainties
Kanno, Yoshihiro,Takewaki, Izuru Techno-Press 2008 Interaction and multiscale mechanics Vol.1 No.1
This paper presents an optimization-based method for computing a minimal bounding ellipsoid that contains the set of static responses of an uncertain braced frame. Based on a non-stochastic modeling of uncertainty, we assume that the parameters both of brace stiffnesses and external forces are uncertain but bounded. A brace member represents the sum of the stiffness of the actual brace and the contributions of some non-structural elements, and hence we assume that the axial stiffness of each brace is uncertain. By using the $\mathcal{S}$-lemma, we formulate a semidefinite programming (SDP) problem which provides an outer approximation of the minimal bounding ellipsoid. The minimum bounding ellipsoids are computed for a braced frame under several uncertain circumstances.
Experimental study on oscillating flow steam engine in a single micro tube
Kanno, Hiroshi,Han, Youngbae,Shikazono, Naoki Elsevier 2017 Experimental thermal and fluid science Vol.81 No.-
<P><B>Abstract</B></P> <P>Oscillating flow steam engine can be a cost-effective solution for recovering work from waste heat due to its structural simplicity. In the present study, the effects of design parameters and operating conditions of oscillating flow steam engine such as tube diameter, heating section temperature, cooling section length ratio and compression ratio are experimentally investigated. The pressure variation due to boiling and condensation induces a continuous oscillating flow in a single micro tube, which can generate work using crank-piston system. The indicated work and cycle efficiency both increase as the heating section temperature and compression ratio are increased. The investigated oscillating flow steam engine achieved indicated work of 1W with the cycle efficiency of <I>η</I> =5% at <I>T</I> <SUB>heat</SUB> =230°C and <I>T</I> <SUB>cool</SUB> =80°C in a <I>D</I> =1.0mm tube.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Oscillating flow steam engine is investigated for waste heat recovery. </LI> <LI> Experimental setup for oscillating flow steam engine in a single micro tube is made. </LI> <LI> Effects of several parameters on heat engine are investigated experimentally. </LI> <LI> Current heat engine achieved 1W work and 5% efficiency between 230°C and 80°C. </LI> </UL> </P>
Holographic dual of de Sitter universe with AdS bubbles
Kanno, S.,Sasaki, M.,Soda, J. North Holland 2012 Nuclear Physics, Section B Vol.855 No.2
We study the proposal that a de Sitter (dS) universe with an Anti-de Sitter (AdS) bubble can be replaced by a dS universe with a boundary CFT. To explore this duality, we consider incident gravitons coming from the dS universe through the bubble wall into the AdS bubble in the original picture. In the dual picture, this process has to be identified with the absorption of gravitons by CFT matter. We have obtained a general formula for the absorption probability in general d+1 spacetime dimensions. The result shows the different behavior depending on whether spacetime dimensions are even or odd. We find that the absorption process of gravitons from the dS universe by CFT matter is controlled by localized gravitons (massive bound state modes in the Kaluza-Klein decomposition) in the dS universe. The absorption probability is determined by the effective degrees of freedom of the CFT matter and the effective gravitational coupling constant which encodes information of localized gravitons. We speculate that the dual of (d+1)-dimensional dS universe with an AdS bubble is also dual to a d-dimensional dS universe with CFT matter.
조선초기 진휼곡 운송 문제: 조선왕조의 국가적 재분배 기능에 대한 고찰

朝鮮半島では, 數年ごとに小規模な饑饉があり, 十數年ごとに大規模饑饉が あった.王朝政府はこれに:對處するために救荒政策, すなわち賑恤政策を實施し た. 本橋では『世宗貿線』等にみえたこの間題に關する史料を分析して, 賑恤穀 の輸送·分配間題を考察した. 副題として「國家的再分配機能の考奈」としたが, これは經濟人類學者のカ-ル·ポラニ-(1886-1964)の市場制度批判·自給·相互扶助·再分配論に示晙 を得ている. まず地方財政と賑恤政策との關係について考寮が必要であった.そして地方財政 はいうまでもなく地方郡縣に所在した倉庫と密接な關係がある.ところ實線史 料では地方の倉庫は多樣な名稱で登場した.しかし實態は全て邑倉を指していた. そして, 收納·保官されている穀物は新穀·舊穀の區別もせず, また財政上の費目 とは無關係に括して管理された.出納時に義倉穀として, あるいは軍資穀とし ての費目で處理した.甚だしくは中央官?へ上納の際に, 不足があれば邑倉の軍 資穀からその不足分を補塡した.すなわち軍資穀は豫備費的財源として利用され ていたのである.そしてこれら地方倉は國家管理であって戶曹が管?した. つづぃて郡縣(邑)內での飢民への賑恤穀支合方法についてみた.被災民が賑 恤米の給貸與を受ける時は.「戶」なぃし個人が單位であった.居性している集 落單位ということではなかった.各「戶」ないし個人が國家機構と相對する關係 であった. 次に賑恤穀の全國的移送問題について檢討した.京畿では賑恤穀の不足の場合 は隣接する忠淸道, 全羅道から漕船で移送した.また京畿では王京の所在地という ことで, 中央政府の所持した備蓄米も賑恤米としてしばしば放出された.これは 隣接する忠淸道, 黃海道の場合も同樣ある.江原道では賑恤米か不足すると, 忠淸道の忠州附近所在し た 慶源倉備蓄穀物から陸路輸送した. 慶源倉はいわゆ る漕倉で 慶尙道の田稅米を -時的に收納したが, これ を江原道 への賑恤米に轉用 したのでゎゐ. 平安道녀は黃海道方面から, 咸吉道고は慶尙·江原道方面輸送から輸送した.また田稅米の收取 · 還上の集散の據點となゐ倉庫が附近たない場合, あゐいは國境に新しい 軍事施設を設けた際, 新倉庫を建設すゐことを命じた. ?境を朝鮮王朝の般行政地域へ組み人た際, 新倉庫を建設すゐことを命じだ. 朝鮮王朝の政治的中央集權は財政的中央集權をもたらし, 中央政府の 指揮の下に地域の?を越えた國家的物流が形成きれた. そして西ヨ-ロツベ·日本 等とは異質な中世社會を生み出した.
