In this article, we propose a mechanical rubbing method to eliminate the optical bounce and decrease the response time of homeotropic liquid crystal (LC) cells with sputtered silicon dioxide alignment films. After gently rubbing the inorganic alignment film (sputtered silicon oxide, SiO2), the decreasing polar anchoring energy results in slightly smaller pretilt angle which gives LC a toppling ...

the proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(x/h)0.5 for low-rise and mid-rise buildings, 2- sin(πx/h) for high-rise buildings. these two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. the assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...

Although numerous studies have reported the physiological strain associated with firefighting, cardiac responses during a large-scale fire operation have not been reported and cardiac responses have not been compared based on crew assignment. The aims of this study were (1) to characterize cardiac strain during simulated high-rise firefighting, and (2) to compare the cardiac strain associated w...

In the present study the slamming problem is simulated by numerical methods for investigating the hydroelastic effect during the slamming process. Slamming with two viewpoints of rigid and elastic structures (hydroelastic effect) had been modeled. Due to high impact speed of slamming, inertial and kinematic effects are quite evident in hydroelastic model. The results showed that considering hyd...

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...

The problem of generating the trajectory for high rise/ high speed elevators is investigated in this paper. Several approaches are used: open loop optimal control, closed loop optimal control and optimization algorithms. Each approach is accompanied by numerical simulations.

Summary In this study, the seismic performance of hexagrid structures which are composed of horizontal and vertical hexagrid by using a transitional story, has been investigated. To this end, 10 models of 50-story hexagrid structures were designed. 9 models with horizontal hexagrid cells which transited to vertical cells using a transitional story, and a model of completely horizontal hexagrid ...
