nvironmental issues and lower fuel conE sumption require improved combustion engines. Several trends point toward use of feedback control directly from combustion, instead of using indirect measurements (as is mostly done today). One such trend is based on new sensors or improved interpretation of available sensor signals. An example is ionization current sensing, obtained by applying a sense v...

A model of a squeezer has been built and experiments are being made (see Fig. VIII-1). A 10-kv pulsed shielded cathode gun of perveance 106 is used to form the beam. The output cavity is very heavily loaded so that it can be used as an "ammeter" (low-impedance) to measure beam current. A polystyrene double-slug tuner allows us to vary the gap impedance over a range of approximately 36:1. The be...

In this paper we consider a model reference adaptive control scheme where the classical error augmentation and standard tuning error normalirat.ion are avoided through the use of Morse's high order tuner. We consider the particular scheme of Morse where the concept of dynamic certainty equivalence is used to reduce the error equation to one that involves only first order dynamics. With such an ...

The digital transition of analog TV is rapidly taking place throughout the world. However, the digital transition of radio is progressing at a slower rate. Diverse standards are being considered for adoption and different countries have different frequencies allocated for digital radio. As a consequence, the progress in the development of digital radio receiver chipsets has been rather stagnant...

Thin film coatings are used to reduce the generation of secondary electrons at the ends of the Advanced Photon Source (APS) rf cavity tuners because these electrons result in increased temperatures on the tuner. To improve the film properties over the existing evaporated titanium film, a magnetron-sputtered film of titanium nitride has been developed that is both harder and adheres more strongl...

1 | P a g e Author: Swaminathan G, Visteon Electronics, India Saminathan V, Visteon Electronics Innovation Head, India. Introduction In the past, automotive audio systems were characterized by simple functionality, a simple tuner, minimal user interface, and primitive two-way communication channels. They were also closed, in the sense that all of the software was loaded pre-sale by the manufact...

Résumé. Les entrepôts de données ont rendu les tâches d’administration et de tuning plus complexes que dans les bases de données traditionnelles. Cela est dû aux caractéristiques des entrepôts de données : la volumétrie, les requêtes complexes, les délais de réponse exigés par les décideurs et la gestion de l’évolution. Dans ce contexte, une panoplie de techniques d’optimisation ont été proposé...

This article is an extension for 2-D analogue signals (and more) of the methods presented in “A nearly One-to-One Method to Convert Analog Signals into a Small Volume of Data” which was published in an earlier issue. This new conversion method may save the storage space, the bandwidth of the transmitting channels and the necessary energy for transmission. It may be particularly interesting for ...

Inharmonicity of piano tones is an essential property of their timbre that strongly influences the tuning, leading to the so-called octave stretching. It is proposed in this paper to jointly model the inharmonicity and tuning of pianos on the whole compass. While using a small number of parameters, these models are able to reflect both the specificities of instrument design and tuner's practice...
