Efficient integrated DC-DC converters for ultra-low voltage energy harvesters
Jayaweera, Herath; Muhtaroğlu, Ali; Sustainable Environment and Energy Systems (2017-8)
The self-starting on-chip fully integrated ultra-low voltage DC-DC converters for energy harvesting applications presented in literature generally have low efficiency and output power capacity. Any improvement in DC-DC converter circuits in terms of energy efficiency, output power, self-starting modes, and voltage gain will contribute significantly to the widespread application of energy harvesters. Two novel fully integrated, self-starting, ultra-low voltage DC-DC converter topologies and model based optim...
Efficient finite difference calculation of partial derivative seismic wavefield using reciprocity and convolution
Sheen, Dong-Hoon; Tuncay, Kağan; Baag, Chang-Eob; Ortoleva, Peter J. (2004-01-01)
Seismic waveform inversion is commonly studied by the least‐squares method which transforms the inverse problem to an iterative minization problem of residuals between the synthetic model response and observed data. One can solve this problem using the gradient method, the Gauss‐Newton method or the full Newton method. The performance of the inverse method depends on the algorithm for calculating the partial derivative seismic wavefield due to perturbations in the subsurface. In this work, 2‐D elastic stagg...

Efficient inertially aided visual odometry towards mobile augmented reality
Aksoy, Yağız; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2013)
With the increase in the number and computational power of commercial mobile devices like smart phones and tablet computers, augmented reality applications are gaining more and more volume. In order to augment virtual objects effectively in real scenes, pose of the camera should be estimated with high precision and speed. Today, most of the mobile devices feature cameras and inertial measurement units which carry information on change in position and attitude of the camera. In this thesis, utilization of in...
Efficient light emitting diodes from polyfluorene copolymer blends
Çırpan, Ali; Karasz, FE (Elsevier BV, 2005-04-30)
Highly efficient light emitting diodes were obtained by blending blue-emitting poly [(9,9-dioctylfluorenyl-2,7-diyl)-alt-co-(N,N'-diphenyl)-N,N-di(p-butyl-oxyphenyl)-1 ,4-diaminobenzene] (1) with green-emitting poly [(9,9-dioctyl-2,7-divinylene-fluorenylene)-alt-co-{2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylene}] (II). Only green emission was obtained from the films of polymer blends and from corresponding double-layer LEDs, indicating an almost complete Forster energy transfer from I to II. These devices sho...
