SEISMIC DESIGN OF DOUBLE LAYER GRIDS BY NEURAL NETWORKS
The main contribution of the present paper is to train efficient neural networks for seismic design of double layer grids subject to multiple-earthquake loading. As the seismic analysis and design of such large scale structures require high computational efforts, employing neural network techniques substantially decreases the computational burden. Square-on-square double layer grids with the va...
متن کاملOptical and Electrical Investigations on GaAs-Based Phototransistors
In order to exploit the potential of phototransistors for vertical-cavity surface-emitting laser (VCSEL) applications, optical and electrical investigations on GaAs-based devices were conducted. The characterization of phototransistors consists of measurements and improvements of the current gain and studies on the spectral behavior. In addition, the influences of various doping concentrations ...
متن کاملHigh-speed PNP PIN Phototransistors in a 0.18 μm CMOS Process
In this work we present three speed optimized types of phototransistors built in a standard 180 nm CMOS technology without process modifications. An OPTO ASIC wafer consisting of a p + substrate with a low doped p epitaxial layer on top of it is used for the implementation. The phototransistors were produced in 40×40 μm 2 and 100×100 μm 2 sizes. A gain in responsivity of more than 13 and bandwi...
متن کاملInvestigation of optically generated kink effect in GaAs-based heterojunction phototransistors
An optically generated kink observed in the Gummel plot of AlGaAs/GaAs single heterojunction phototransistors (sHPTs) is reported when illuminated with relatively high optical powers. The observed sudden rise in collector current and decrease in the base current, referred to as ‘optical kink effect’, is carefully studied and analyzed. The measurements are performed for incident optical power of...
