On the basic contrasts in PBIB designs

Construction of Rectangular Pbib Designs

In this paper, some methods of constructing rectangular PBIB design are presented using the incidence matrix of a known PBIB design and Hadanard matrix. The rectangular design so constructed has nice block structure properties. The dual of these rectangular designs generate semiregular GD designs. A rectangular design is also constructed by using treatments arranged in n square array. Dual of t...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
