This report presents a novel, cascaded approach to non-linear acoustic echo cancellation (AEC). The loudspeaker enclosure microphone (LEM) system is divided into two blocks: non-linear clipping and power filtering, and a conventional, linear AEC. They represent the non-linear amplifier and loudspeaker and linear acoustic channel and up-link path in a typical mobile communication scenario. We pr...

Results from several experiments were reviewed to collect information on the value of piglet " needle-neeth " clipping. The incidence of facial and udder lesions generally is increased when teeth are left intact. However, there is no evidence that these lesions affect piglet mortality or weaning weight. Thus, based on the conditions of these experiments, there is no strong justification for tee...

In Orthogonal Frequency Division Multiplexing (OFDM) systems, the peak to average power ratio (PAR) is much high. The clipping signal scheme is a useful method to reduce PAR. Clipping the OFDM signal, however, increases the overall noise level by introducing clipping noise. It is necessary to recover the figure of the original signal at receiver in order to reduce the clipping noise. Considerin...

Multiple color coordinate systems are usually involved in color image applications or systems. Forward and backward transformations are used to switch between color coordinate systems. The out of gamut problem emerges when the color coordinate systems’ gamut is different. Conventional approaches, including clipping R, G, B values and clipping luminance value are not ideal as they both produce s...

BACKGROUND AND PURPOSE The management of aneurysms is controversial because little is known about the impact of clipping on long-term outcome. This study was designed to evaluate long-term survival of patients with aneurysms undergoing clipping in a statewide population. METHODS We used a retrospective design using an administrative database to identify patients hospitalized with aneurysms (1...

Internal carotid-posterior communicating artery (IC-PC) aneurysms account for more than 20% of all intracranial aneurysms. As a result of the increase in coiling, there has also been an increase in recurrent IC-PC aneurysms after coiling. We present our experience of 10 recurrent IC-PC aneurysms after coiling that were retreated using surgical or endovascular techniques in order to discuss the ...

Smart grid can be a solution for reducing greenhouse gas (GHG) emissions. To perform its task, smart grid needs a communication link to communicate between nodes or devices. Using power-line communications (PLC) is beneficial as the power-lines infrastructure has been available. However, in PLC the transmitted signal undergoes multipath channels and impulsive noise corruption. Meanwhile, orthog...

This study was carried out to establish clipping interval of Pennisetum orientale (PO) and Panicum antidotale (PA) to get maximum biomass production with optimal nutritional value for Nili buffaloes. Two clipping intervals i.e. CI1, and CI2 (clipped after every one and two months, respectively) were studied for both grasses. The data on various parameters were compared with PO and PA each clipp...
