High Speed Delay-Locked Loop for Multiple Clock Phase Generation

In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...

Robust Tracking for High Rise/High Speed Elevators

Jing Li David Niemann Hua O. Wang Department of Electrical and Computer Engineering Duke University, Durham, NC 27708, U.S.A Abstract This paper deals with control design for the motion control of high-rise/high-speed elevators. Two main problems, tracking and releveling, are treated in the framework of output regulation problem. By doing this, we design a single controller satisfying both perf...

Factors Influencing Failure Emergency Evacuation in Work Environments during Fire

One of the necessary measures of saving human life in emergency situations, such as fires, is the safe and swift evacuation of people. The prerequisites for this are to anticipate, identify, and eliminate factors preventing people from leaving buildings in a timely and safe manner while moving them to a safe place [1]. The occurrence of errors caused by engineering, design, human, and psycholog...

Explanation of the physical factors affecting the mental image of residents of high-rise residential buildings

When dealing with a diverse and rich environment, humans record limited information in their minds, and this information forms a comprehensive, albeit inaccurate, mental image of the environment. On the other hand, living in high-rise residential buildings in Iran is always associated with dissatisfactions that a clear mental image in the minds of the residents can reduce these dissatisfactions...
