This paper introduces an optical 2-axis Micro Electro-Mechanical System (MEMS) micromirror actuated by a pair of electrothermal actuators and a set of passive torsion bars. The actuated element is a dual-reflective circular mirror plate of 1 mm in diameter. This inner mirror plate is connected to a rigid frame via a pair of torsion bars in two diametrically opposite ends located on the rotation...
In design steel frames, combining semi-rigid and rigid connections can result in better structural performance, particularly seismic locations. this study, the effects of beam-to-column located on performance frame structures are investigated. The analysis uses six twelve-story moment resisting frames (MRSF) with rigid, semi-rigid, dual beam-column connections. These designed according to Egypt...
A three-storey aluminium space frame is modelled using beam elements with unrepresentative rigid joints. Five model-updating experiments are carried out using di!erent sets of updating parameters. All of them are shown to produce improved predictions, even for modi"ed con"gurations of the frame. The set of parameters that on average produces the best results is also considered to provide a phys...
In this paper we present a new discriminative approach to achieve consistent and efficient tracking of non-rigid object motion, such as facial expressions. By utilizing both spatial and temporal appearance coherence at the patch level, the proposed approach can reduce ambiguity and increase accuracy. Recent research demonstrates that feature based approaches, such as constrained local models (C...
