Power electronic systems have a great impact on modern society. Their applications target more sustainable future by minimizing the negative impacts of industrialization environment, such as global warming effects and greenhouse gas emission. devices based wide band gap (WBG) material potential to deliver paradigm shift in regard energy efficiency working with respect mature silicon (Si). Galli...

This paper introduces an efficient Field Programmable Gate Array (FPGA) realization of a multirate decimation filter with narrow pass-band and narrow transition band for Noise thermometer application. The filter is composed of three stages; the first stage is a Cascaded Integrator Comb (CIC) decimation filter, the second stage is a two-coefficient half-band (HB) filter and the last stage is a s...

In this paper, we analyze the performance of cross-band adaptation in the short-time Fourier transform (STFT) domain for the application of acoustic echo cancellation. The band-to-band lters and the cross-band lters considered in each frequency-band are all estimated by adaptive lters, which are updated by the LMS algorithm. We derive explicit expressions for the transient and steady-state mean...

To investigate the hole transport across amorphous/crystalline silicon heterojunctions, solar cells with varying band offsets were fabricated using amorphous silicon suboxide films. The suboxides enable good passivation if covered by a doped amorphous silicon layer. Increasing valence band offsets yield rising hole transport barriers and reduced device effciencies. Carrier transport by thermal ...

Filter design specifications can be manifest in all manner of necessity, whether they are high-pass, low-pass, band-pass, or stop-band filters. In addition, the parameters for such filters are defined for a very specific application. A design for a lowpass filter with a pass-band of 2k Hz and a stop-band of 4k will be discussed. The further properties of the filter are to allow for a 48 dB drop...

A field micro-plot experiment using nitrogen isotope (15N) labeling was conducted to determine the effects of placement methods (broadcast and band) and N rates (60, 150 and 240 kg ha-1) on the fate of urea-15N in the wheat-soil system in Guangde County of Anhui Province, China. N fertilizer applied in bands increased grain yield by 15% compared with broadcast application. The N fertilizer appl...

We present Gibber: a live coding environment for web browsers. Gibber performances are written in pure JavaScript with no syntactical additions or modifications; this enables Gibber code to be executed in any web page viewed inside a browser implementing a realtime audio API. Gibber offers an array of synthesis options (FM, granular, subtractive, physical modeling), audio effects and sequencing...
