Traditional flicker detection methods accurately extract the amplitude envelope as the premise, the complexity of large amount of computation. This paper presents a new real-time detection of voltage flicker method, analysis method with recursive frequency carrier signal frequency; use of the adjacent three-point sampling data, the frequency carrier signal frequency, sampling frequency voltage ...

Abstract—This study is purposed to develop an efficient fault detection method for Global Navigation Satellite Systems (GNSS) applications based on adaptive noise covariance estimation. Due to the dependence on radio frequency signals, GNSS measurements are dominated by systematic errors in receiver’s operating environment. In the proposed method, the pseudorange and carrier-phase measurement n...

Halide perovskites have been considered as nuclear radiation detection materials due to their high mobility, long carrier lifetime, and absorption coefficient. However, it has reported th...

An efficient analytical and simulation techniques were developed to analyze the bit error rate of PSK Nakagami-m fading systems with imperfect carrier recovery. We evaluate the detection loss due to the carrier recovery for different rms phase error values when coherent BPSK and QPSK systems are used in wireless channels. Our results are useful in designing practical systems and will enable des...

This paper describes a Ground Based Augmentation System (GBAS) ground-based monitor capable of instantly detecting anomalous ionospheric gradients at the time of satellite acquisition. The monitor utilizes differential carrier phase measurements across multiple reference station baselines as the basis for detection. Performance analysis shows that the monitor is highly sensitive to the quality ...

In this paper we propose an enhanced version of the DCSK (Differential Chaos Shift Keying) scheme where the carrier symbolic dynamics are exploited for conveying useful information. This is achieved by means of a pseudo-chaotic encoder which spreads the input sequence approximating the dynamics of the Bernoulli shift. The information encoded in the pseudo-chaotic carrier is retrieved by using s...

Analysis is done on the inter-carrier interference (ICI) that caused by multi-carrier communication system frequency offset. The application model of DFT/IDFT in ADSL access network is analyzed further; the hardware detection and software analysis scheme of the system are proposed for the accessing network. Experiments have proved that monitoring system can filter the network data flow and carr...

Background and Objectives: Beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. Although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. Thus, the objectives are to study the validity of Naked-Eye-Single-Tube-Osmotic-Fragility-Test (NES...

A carrier offset correction scheme based on Maximum Likelihood (ML) method for the downlink of an Orthogonal Variable bit rate Multicarrier-CDMA (MCCDMA) scheme in a fast frequency selective Rayleigh fading channel is proposed and discussed. The proposed methodology assumes perfect knowledge of phase offset, whereas an Equal Gain Combining (EGC) scheme is considered for MC-CDMA detection. Resul...

For endometrial cancer The ACS recommends that women at very high risk for endometrial cancer due to 1) known HNPCC genetic mutation carrier status; 2) a substantial likelihood of being a mutation carrier (ie, a mutation is known to be present in the family); or 3) the absence of genetic testing results in families with a suspected autosomal dominant predisposition to colon cancer should consid...
