Automated Quality Control

We consider the task of automated quality control of sound recordings containing voice samples of individuals. It is shown that in this task the most acute is the small sample size. In order to overcome this problem, we propose the novel method of acoustic measurements based on relative stability of the pitch frequency within a voice sample of short duration. An example of its practical implementation using aninter-periodic accumulation of a speech signal is considered. An experimental study with specially developed software provides statistical estimates of the effectiveness of the proposed method in noisy environments. It is shown that this method rejects the audio recording as unsuitable for a voice biometric identification with a probability of 0,95 or more for a signal to noise ratio below 15 dB. The obtained results are intended for use in the development of new and modifying existing systems of collecting and automated quality control of biometric personal data. The article is intended for a wide range of specialists in the field of acoustic measurements and digital processing of speech signals, as well as for practitioners who organize the work of authorized organizations in preparing for registration samples of biometric personal data.

Vorgestellt wird ein Maschinenprototyp zur Feinbearbeitung von Werkstückkanten und -oberflächen. Dieser verfügt über integrierte optische Messtechnik, die zur Kontrolle der Bearbeitungsergebnisse und gegebenenfalls zur automatisierten Nachbearbeitung eingesetzt werden kann. Mit dem Prototypen werden zum einen Fräswerkzeuge präpariert und zum anderen die Prozessparameter und deren Effekte analysiert. Abschließend beschreibt der Fachbeitrag einen Ansatz zur automatisierten Auslegung der Prozessparameter.   This paper presents a machine prototype for the finishing of edges and surfaces of work pieces. The prototype has an integrated optical measurement device, which can be used for the control of the process results and possibly automated remachining. The machine is used for the preparation of milling tools. Process parameters and their effects are analyzed and an approach for the automated setting of the process parameters is shown.

The present state of laser glasses production for optoelectronic systems and devices is considered. The limitations of existing laser glasses and the necessity to create new ones have been viewed. The urgency of the development and introduction of new types of laser glass for its use in both civilian and defense equipment sectors is shown. The technological complexity of the phosphate erbium glasses production is substantiated. The purpose of the work is to create laser glasses and make a laser element, will be operating wavelength of 1.54 μm. Optimum concentration of rare earth oxides in laser glasses has been determined. The quality control methodology and technology of laser glasses were developed. The production of a new laser glass makes it possible to use it in modern optoelectronic systems. The laser elements were fabricated and their generation characteristics were investigated. The results of the laser elements industrial testing are presented.
