in this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. to achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. the length of gasper air flow was compared with the distance between gasper outlet and...

Pathogen-mediated competition, through which an invasive species carrying and transmitting a pathogen can be a superior competitor to a more vulnerable resident species, is one of the principle driving forces influencing biodiversity in nature. Using an experimental system of bacteriophage-mediated competition in bacterial populations and a deterministic model, we have shown in Ref. [28] that t...

Manufacturing process frequently employs optimization of machining parameters in order to improve product quality as well as to enhance productivity. The material removal rate is a significant indicator of the productivity and cost efficiency of the process. Taguchi method has been implemented for assessing favorable (optimal) machining condition during the machining of nylon by considering thr...

there exist simple theories to predict the strain of sandwich structures under a bending load and specific support conditions. although theoretical predictions are highly effective, but the role of testing in validation of these theories and their progress is undeniable. the main goal of the present paper is to prepare a test instruction in order to minimize the error of data acquisition and th...
