Studies on Variations in Sky View Factors of a Forest Using an All-Sky Photograph Model.
Journal of Japan Society of Hydrology and Water Resources, 1998 魚眼レンズの射影方式を参考に作成した全天写真モデルを用い,針葉樹林,非着葉状態の落葉樹林における全天開空率(P),太陽経路開空率(Q)を求め,樹高,植樹間隔が各森林のP,Qに与える影響,並びに樹木形状によるP-Q関係の相違を明らかにした.さらに森林方位の違いに基づく太陽経路開空率の変化について考察した.全天,太陽経路開空率は,それぞれ散乱放射,直達放射に対する森林の透過率として用いることができるため,森林内に透過する放射量を議論する上で重要な因子となる.両森林とも,樹高が低く,植樹間隔が広くなるほど全天,太陽経路開空率は上昇する.P-Q関係に及ぼす樹高の影響は,特に針葉樹林の太陽経路開空率に現れ,植樹間隔の影響は,針葉樹林,落葉樹林の全天開空率に認められた.P-Q関係は樹形によって異なり ...

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Different aspects in the quantification of the Sky View Factor in complex environments. [PDF]
, 2014 This paper examines potential applications of the sky view factor (SVF) regarding two- or threedimensional sites. First, the concepts of the radiation budget, Lambert's cosine law and hemispherical description of radiating of en vironments are introduced

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
