The status of our development of strip anode MRPCs in the framework of the FOPI-ToF upgrade project is reviewed. For the counter readout we have developed a fast FEE (front-end-electronics) offering a high gain ða 200Þ at high bandwidth ðdf 1000MHzÞ and a new TAC-digitization system with an internal resolution of stp15 ps. In order to optimize the signal shape variations, strip/pitch configurat...

the chromatic dispersion curve of the fundamental mode in small core microstructured fibres (SCMF) is both calculated using a Finite Element Method (FEM) and measured with a low coherence interferometric method. The great sensitivity of the chromatic dispersion to variations of the geometrical parameters of SCMFs (the pitch  and the diameter d) is pointed out. An excellent agreement is obtaine...

The robustness of agility metrics has been studied to determine the sensitivity of selected metrics to variations in initial conditions and uncertainties in physical characteristics and coefŽ cients. The selected metrics are time to roll through bank anglemetric, time-averaged integral of pitch rate metric, and power onset/loss parameter. Each metric was evaluated with initial condition errors ...

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...

We have examined a tonal system of modern Hanoi dialect of Vietnamese. This has been described for a long time as a pitch contour prominent system with secondary phonatory variations. The present study aims to propose certain laryngeal features, [tense] and [glottal constriction], in addition to the former prosodic feature, [high], to cover the overall distinction within the system. Some acoust...

This paper presents the JD-1, a digital controller for analog modular synthesizers. The JD-1 features a capacitive touchsensing keyboard that responds to continuous variations in finger contact, high-accuracy polyphonic control-voltage outputs, a built-in sequencer, and digital interfaces for connection to MIDI and OSC devices. Design goals include interoperability with a wide range of synthesi...

New generation of speech coders have to achieve two goals: efficient use of bandwidth and high speech quality. The objective of this thesis is to improve the modelling of speech signal within the constraints of a low bit rate coder. Many speech coding algorithms use Linear Prediction (LP) coefficients to describe the power spectrum of the speech. These parameters are obtained for blocks of inpu...

The article describes the system we submitted for the three sub-challenges of INTERSPEECH 2012 Speaker Trait Challenge for the classification of the five personality traits of OCEAN, likability and intelligibility. The system was based on a two-class SVM-classifier using leave-one-speaker-out cross-validation to optimize SVM complexity parameter and to select the feature set for trait classific...

Various computer vision problems and applications rely on an accurate, fast head pose estimator. We model head pose estimation as a regression problem. We show that it is possible to use the appearance of the facial image as a feature which depicts the pose variations. We use a parametrized Multi-Variate Relevance Vector Machine (MVRVM) to learn the three rotation angles of the face (yaw, pitch...

|We propose methods to track natural variations in the characteristics of the vocal-tract system from speech signals. We are especially interested in the cases where these characteristics vary over time, as happens in dynamic sounds such as consonant-vowel transitions. We show that the selection of appropriate analysis segments is crucial in these methods and we propose a selection based on est...
