The problem of how we perceive the shape of an object in space is complicated by the optical fact that to a particular retinal form there does not correspond a unique physical form but a whole set of possible physical forms. A given sheaf of light rays whose cross section is a particular form may be reflected from any surface whose margins coincide with the margins of the sheaf of rays; the sur...

Foundations of structures which are subjected to uplift loading require anchoring systems to resist pullout loads. Such anchors can be broadly classified as gravity anchors, pile anchors and plate anchors. Plate anchors can be circular, square or strip in shape. The loading applied on plate anchors can be vertical, inclined or horizontal depending on the anchor orientation. In this study, vario...

This paper presents the experimental study of pressure and velocity fluctuations and their interdependence, in the turbulent flow impinging on arrangements of yawed circular cylinders simulating inclined tube banks with square arrangement and a pitch to diameter ratio of 1.26. Measurements were performed with hot-wires and a pressure transducer. Behaviour of fluctuating quantities is described ...
