The article is related to the field of geodetic and engineering construction monitoring building structures in form rod systems. It investigates measurement accuracy compression deformation rod. As an example, there considered a vertical rectilinear high flexibility, loaded with longitudinal axial force. Experience demonstrates that rod, under influence compressive load not exceeding permissibl...

the relative eye size, types of visual cell and mosaic, and the existence of retinal tapetum in the eyes of the spotted barb puntius binotatus were determined to gain baseline information on its visual capability. the p. binotatus acquired relatively larger eye size than the other similar sized freshwater fish species with its retina being contained both cone and rod visual cells (cone ellipsoi...

正方形の断面を持つ石英ガラス棒の隣接する2面に0と45 nm，または30と70 nmの異なる膜厚の組合せで金薄膜層を形成して表面プラズモン共鳴（SPR）センサーとし，一端から入射した無偏光を他端の偏光板で偏光方向を選択することで，SPR現象がp偏光のみで起こることを利用してセンサーの応答面を選択できることを見いだした．センサーの応答特性は多層フレネル等式を用いて計算された理論曲線とよい一致を示し，理論により応答特性の予測が可能であることも確認された．また，受光部の偏光板の代わりに偏光ビームスプリッターを用いて偏光を二つに分け，2面の同時かつ独立の測定を試みた．その結果，偏光ビームスプリッターの分離特性の影響を受けるが，2面の応答を同時かつ独立して測定が可能であることが分かった．これらの研究により，角型ガラス棒と偏光を組み合わせることによる応答面の選択という，センサー開発における新しい...

Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...

We find that a column of glass beads exhibits a well-defined transition between two phases that differ in their resistance to shear. Pulses of fluidization are used to prepare static sedimented states with well-defined particle volume fractions φ in the range 0.57–0.63. The resistance to shear is determined by slowly inserting a rod into the column of beads. Force measurements and bed height me...

in this research, a braiding-pultrusion production line is developed by modifying a conventional textile maypole braiding machine and adding it to a pultrusion line for production of braid-pultruded (bp) composite rods. in order to evaluate the mechanical properties of bp rods and study the effect of some braiding parameters, they were produced with different braid roving linear densities and b...
