A microactuating structure with vertical polyimide hinges has been designed, fabricated and tested. Unlike traditional microactuators, which are located on the substrate surface, this new actuation mechanism is capable of producing linear motion at a point far from the substrate. This advantage can make it possible to drive other out-of-plane folded structures for on-wafer or out-of-wafer appli...

In this work we present an adaptive method for detection of Brazilian license plate. This method enhances adaptively an input image, improving low contrast areas and guaranteeing a good contrast in the plate region. Based on the fact that license plate’s area is rich in texture and vertical edge information, we can identify it after filtering the image with Sobel and Canny operators eliminating...

Vertical load was applied uniformly over the entire top surface of the plate, and the load was increased in increments. For each load increment, the equilibrium state of the problem was determined. Because of the continuously hardening postyield behavior of Titanium Grade 7, equilibrium could be achieved for any vertical load. However, at a certain load level, the region of the plate between th...

Experimental investigations has been done to find out the heat transfer characteristics and friction factor of water based Al2O3 nanofluids as a coolant in  brazed plate heat exchanger. Plate heat exchanger either use horizontally or vertically. The base plate of the plate heat exchanger was kept inclined at (0⁰, 30⁰ ,60⁰, 90⁰). The experimentation have been done on the two different concentrat...

The author's recent investigations on plate theories form the basis to review development of plate theories. In spite of several review articles on plate theories reported in the literature, the present work is essentially due to Jemielita's inspiring article (1993). It is shown that methods of analysis based on vertical displacement as domain variable deal with solution of associated torsion p...

Consider a vertical plate with a leading edge. The temperature of the plate is above the spontaneous nucleation temperature, so that vapor completely covers the plate. Two-dimensional quasi-parallel theory is used to examine the stability of the two-phase system. Numerical calculations show that the main parameter determining the thickness of the vapor film and its stability is the difference b...

Fig. 1 a —c. Motion sensitive neurons of the lobula plate of Calliphora erythrocephala stained by intracellular injection of procion yellow. The tracings (a, b) were obtained from 12 «m frontal sections and show the injected cells drawn into a semi-schematic vertical elevation of the brain (lateral structures, indicated by thin lines: lobula plate and medulla; oval structure in the center: oeso...
