چکیده

The factor transducer of a word associates to each of its factors (or subwc~rds) their first occurrence. Optimal bounds on the size of minimal factor transducers together with an algorithm for building them are given. Analogue results and a simple algorithm are given for the case of subsequential suffix transducers. Algorithms are applied to repetition searching in words. Rl~sum~. Le transducteur des facteurs d 'un mot associe a chacun de ses facteurs leur premiere occurrence. On donne des bornes optimales sur la taille du transducteur minimal d'un mot ainsi qu 'un algorithme pour sa construction. On donne des r6sultats analogues et un algorithme simple dans le cas du transducteur sous-s~luentiel des suffixes d 'un mot. On donne une application la d6tection de r6p6titions dans les mots.

Impact Analysis of Variation in Geometrical Features on Intrinsic Characteristics of Capacitive Micro-machined Ultrasonic Transducers

Capacitive Micro-machined Ultrasonic Transducers (CMUTs) are the ultrasonic devices which produce better features in contrast to piezoelectric transducers. The intrinsic parameter of CMUT varies with the variation in geometrical dimension of the device. The cavity height and the radius of the CMUT with circular membrane is varied in the lumped parallel plate model for its impact on the paramete...

Piezoceramic Element Design and Fabrication for Ultrasonic Transducer of Gas Meter

Ultrasonic transducers play a significant role in generating and receiving the acoustic waves in ultrasonic flowmeters. Depending on the required accuracy, the ultrasonic transducers can be installed either in one pair or more in an ultrasonic flowmeter. The main part of an ultrasonic transducer is its piezoceramic element. In this work, four piezoceramic elements with different diameter to thi...

معرفی روش تطبیقی اصلاح شده برای اندازه‌گیری دقیق ولتاژ در مبدل ولتاژ نوری

There are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. Although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

The influence of task frequency and force direction on psychophysically acceptable forces in the context of the biomechanically weakest links.

This study examined the influence of frequency and direction of force application on psychophysically acceptable forces for simulated work tasks. Fifteen male participants exerted psychophysically acceptable forces on a force transducer at 1, 3, or 5 repetitions per minute by performing both a downward press and a pull toward the body. These exertions were shown previously to be strength and ba...
