This paper presents a detailed parametric analysis of the impact geometrical characteristics wind catchers on their flow features to enhance effectiveness cross-ventilation strategies buildings. The following are evaluated in detail: (i) ceiling tilt angle, (ii) radius outer-corner bend, (iii) leeward-side (iv) straight inlet extension length, (v) nozzle-shaped radius, and (vi) inner-corner ben...

Mini and micro robots, which can swim in an underwater environment, have drawn widespread research interests because of their potential applications to the clinical drug delivery, biotechnology, manufacturing, mobile sensor networks, etc. In this paper, a prototype of microrobot based on the motion principle of living microorganisms such as E. Coli Bacteria is presented. The properties of this ...
