Fundamental oscillation up to 1.08THz in resonant tunneling diodes with high-indium-composition transit layers for reduction of transit delay

Fundamental oscillations up to 1.08 THz with the output power of 5.5 microwatts was achieved in GalnAs/AlAs resonant tunneling diodes (RTDs) at room temperature. The graded emitter, thin barriers, and high-indium-composition transit layers were introduced to reduce the tunneling and transit delays. The first two of these structures are the same as those in RTDs oscillating at 1.04 THz reported ...

Feature extraction for nearest neighbor classification: Application to gender recognition

In this article, we perform an extended analysis of different face-processing techniques for gender recognition problems. Prior research works show that support vector machines (SVM) achieve the best classification results. We will show that a nearest neighbor classification approach can reach a similar performance or improve the SVM results, given an adequate selection of features of the input...

Development of Neural Networks for Noise Reduction

This paper describes the development of neural network models for noise reduction. The networks used to enhance the performance of modeling captured signals by reducing the effect of noise. Both recurrent and multi-layer Backpropagation neural networks models are examined and compared with different training algorithms. The paper presented is to illustrate the effect of training algorithms and ...

The Soundness of Explicit Substitution with Nameless Variables

We show the soundness of a-calculus B where de Bruijn indices are used, substitution is explicit, and reduction is step-wise. This is done by interpreting B in the classical calculus where the explicit substitution becomes implicit and de Bruijn indices become named variables. This is the rst at semantics of explicit substitution and step-wise reduction and the rst clear account of exactly when...

A New Optimum-Word-Length-Assignment (OWLA) Multiplierless Integer DCT for Unified Lossless/Lossy Image Coding

Recently, we proposed a new multiplierless 1D Int-DCT modified from our existing Int-DCT by approximating floating multiplications to bit-shift and addition operations. The multiplierless 1D Int-DCT can be well operated both lossless coding and lossy coding. However, our multiplierless 1D Int-DCT is not focused on how to assign word-length for floating-multiplier approximation as short as possi...
