Compression is the automatic reduction of gain as the signal level increases beyond a preset level called the threshold. It is an automatic version of “gain riding”, where one might manually lower a fader as the signal grows larger to maintain a more constant output level. For signals above the threshold, the increase in output amplitude for a given increase in input amplitude is known as the c...

A new transformerless quadratic buck–boost converter with a common ground and high-voltage gain ratio of D/(1?D)2 is proposed in this study. The output input currents the structure are continuous due to presence inductive filters ports. continuity current simultaneously reduces voltage ripple also capacitor stress at port. With structure, lower total switching device power higher attained same ...

This paper proposes a design method of generalized minimum variance control (GMVC) using strong stability rate. Strong stability rate is a novel and simple concept for plant safety, and it is defined by ratio of the open-loop gain and the closed-loop gain of controlled system through YoulaKucera parametrization. For safety, it is desirable that the open-loop output is closer to the closed-loop ...

In automatic speech grading systems, rare research is followed through addressing the issue of GOR (Goodness Of pRosody). In this paper we propose a novel method by taking the advantage of our QBH (Query By Humming) techniques in 2008 MIREX evaluation task. A set of standard samples related to the top-cream students are initially picked up as templates, a cascade QBH structure is then taken fro...

A new generic object recognition (GOR) method for robot perception is proposed in this paper, based on multi-feature fusion of two-dimensional (2D) and 3D scale invariant feature transform descriptors drawn from 2D images and 3D point clouds. The trained support vector machine is utilized to construct multi-category classifiers that recognize the objects. According to our results, this new GOR ...

In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...

BACKGROUND Gastro-oesophageal reflux (GOR) is an extremely common and usually self-limiting condition in infants. When treatment is required, Cisapride, a pro-kinetic agent, has been commonly prescribed for the symptomatic management of GOR. There have been recent reports of possibly serious adverse events, e.g. an increased QTc interval, cardiac arrhythmias, and death, associated with the use ...

The diagnosis of gastro-oesophageal reflux (GOR) is of great interest for paediatric gastroenterologists. pH monitoring is the commonly used procedure for GOR diagnosis but a major amount of postprandial GOR is missed due to the mostly non-acidic gastric contents in infants. The multiple intraluminal impedance technique is based on the recording of the impedance changes during bolus transport i...
