We employ a new method for studying compositionally disordered ferroelectric oxides. This method is based on the virtual crystal approximation (VGA), in which two or more component potentials are averaged into a composite atornic potential. In our method, we construct a virtual atom with the correctly averaged atomic size and atomic eigenvalues. We have used our new method to study the composit...

This paper presents a novel FPGA implementation of a two dimensional (8x8) point Discrete Cosine Transform. It is shown how the development of a suitable architectural style can produce high quality circuit designs for a specific technology, in this case the Xilinx XC6200 series of FPGA. Distributed arithmetic and exploitation of parallelism and pipelining are used to produce a DCT implementati...

We propose a principled convolutional neural pyramid (CNP) framework for general low-level vision and image processing tasks. It is based on the essential finding that many applications require large receptive fields for structure understanding. But corresponding neural networks for regression either stack many layers or apply large kernels to achieve it, which is computationally very costly. O...

The robot localization problem is a fundamental and well studied problem in robotics research. Algorithms used to estimate pose on the map are usually based on Kalman or particle filters. These algorithms are able to cope with errors, that arise due to inaccuracy of robot sensors and effectors. The performance of the localization algorithm depends heavily on their quality. This work shows perfo...

With these issues in mind, we designed an audio-controlled digital oscillograph that uses an audio recognition algorithm to control the oscillograph; specifically, it controls the waveform display size attenuation and amplification as well as the scanning speed. The oscillograph display uses a standard VGA interface that can display waveforms on a PC monitor, projector, or other standard output...

The large data-transfer time among different cores is a big problem in heterogeneous multi-core processors. This paper presents a method to accelerate the data transfers exploiting data-transfer-units together with complex memory allocation. We used block matching, which is very common in image processing, to evaluate our technique. The proposed method reduces the data-transfer time by more tha...

The working principle of large optical transceiver is introduced in this article, and the time division MUX and the time division DEMUX are designed by the online system programmable technology and the FPGA (Field Programmable Logic Array), including hardware design, software design, and testing. The transmitting design and the receiving design method of time division MUX are introduced in deta...

An interactive Segmentation and Labelling Automatic Module (SLAM), especially developed for Windows-based Personal Computers, is described. The system is extremely user-friendly and it was designed with the aim of supporting speech scientists in assessing the very heavy and time-consuming task of segmenting a big amount of speech material such as that caused by the tremendous spread of new and ...
