Pollution Level Estimation for Tunnel Ventilation Control.

Application of fuzzy control to a road tunnel ventilation system

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

VOC level control by ventilation improvement of Flexography printing room using CFD modeling

Using Computational Fluid Dynamics (CFD) technique, the dispersion contours and the exposure rate of Flexographic printing workers to VOCs in a printing department is evaluated. Firstly, VOCs distribution is determined in the printing room due to the existing ventilation system. Through next steps, 4 scenarios for lowering VOCs concentration and its exposure rate to workers are analyzed. Concen...

Ventilation System Design for a Roadway Tunnel in Acapulco, México

There are several industrial methods for tunnel ventilation system design. In particular, for tunnels where axial flow fans are applicable, there are specialized computer programs that calculate the various pressure drops that consider wall friction and local losses due to signs and appurtenances, and considering vehicle emission factors based on up-hill or down-hill conditions, determine the n...

Fast High - level Power Estimation for Control - owIntensive

In this paper, we present a power estimation technique for control-ow intensive designs that is tailored towards driving high-level synthesis systems, where hundreds of architectural trade-oos are explored and compared. Our method is both fast and accurate. The algorithm utilizes the behavioral information to extract branch probabilities, and uses these in conjunction with switched capacitance ...
