    Application of Wavelet Transform for Determining Diagnostic Signs
    (CEUR-WS, 2019-06) Babikova, Kateryna; Isaienko, Volodymyr; Eremenko, Volodymyr; Zaporozhets, Artur
    It is proposed to apply the wavelet transform to localize in time the frequency components of the information signals in this article. The wavelet transform allows to fulfil time-frequency analysis of signals, which is very important for studying the structure of a composite material from the mode composition of free oscillations. The proposed approach to the development of information signals using wavelet transform makes it possible to further study the nature of the occurrence of free oscillations and the propagation of acoustic waves in individual layers of composites and to study the change in the structure of composites from the changes in the three-dimensional wavelet spectrum.

    Quality assurance services and products – the basis of agritourism in Ukraine
    (2015-05) Babikova, Kateryna; Бабікова, Катерина Олександрівна
    Агротуристична діяльність – пріоритетний напрямок розвитку туристичної діяльності в Україні. Масовість відпочинку, рекреаційна привабливість регіонів зумовлюють до постійного моніторингу й контролю за якістю основних компонентів довкілля (атмосферне повітря, ґрунт, питна вода, рослинницька продукція тощо), а також послуг, які надаються туристам. Відсутність статистичних даних, організованих, систематичних досліджень і зумовлюють актуальність та практичну значимість отриманих результатів. Проведення комплексного аналізу екологічної ситуації в регіонах, залучених до агротуризму відіграє важливу роль у забезпеченні якості послуг та продукції. По-перше, агротуристична діяльність тісно взаємопов’язана зі станом природно-ресурсного потенціалу, по-друге, розвиток аграрного туризму певною мірою залежить від екологічних факторів. Вагомим аспектом забезпечення якості продукції та послуг є екологічна паспортизація та категоризація агросадиб (у відповідності до існуючих національних і міжнародних стандартів). Агросадиби, які пройшли екологічну паспортизацію та отримали відповідний сертифікат, в першу чергу гарантують високу якість послуг та охочіше відвідуються екологічно свідомими туристами. Введення у практику системи екологічної паспортизації й категоризації дозволяє власникам агросадиб: підвищити конкурентноздатність на ринку агротуристичних послуг; розширити обсяги вирощення екологічно чистої продукції; збільшити число відпочиваючих в садибах; отримати більше прибутків; підвищити екологічну свідомість та культуру тощо . Управління якістю продукції та послуг в сфері аграрного туризму є вкрай необхідним та, на жаль, не вирішеним завданням. А тому, на порядку денному повинно стояти питання щодо забезпечення якісного відпочинку та оздоровлення людини в сільських регіонах з екологічно сприятливими умовами, однак з найменшим (практично відсутнім) впливом на довкілля.

    Using hilbert transform in diagnostic of composite materials by impedance method
    (Periodica polytechnica electrical engineering and computer science, 2020-08-13) Eremenko, Volodymyr; Zaporozhets, Artur; Babak, Vitalii; Isaienko, Volodymyr; Babikova, Kateryna
    The article is devoted to the problem of the increasing of information quality for the impedance method of nondestructive testing. The purpose of this article is to get for the pulsed impedance method of nondestructive testing the additional informative parameters. Instantaneous values of the information signal's amplitude is a sensitive parameter to the effects of interference, in particular friction, which necessitates the use of additional informative features. It was experimentally measured signals from defective and defectless areas of the test pattern. Using of the Hilbert transform gave possibility to determine phase characteristics of these signals and realize demodulation to extract a low-frequency envelope for further analysis of its shape. It was received the informative features as a result of researches. Among them are instantaneous frequency of a signal, the integral of a phase characteristic on the selected interval and the integral of a difference signal phase characteristics. In order to compare quality of the defect detection using selected parameters it was carried out evaluation of the testing result reliability for a product fragment made of a composite material. Considering the influence of the change in the mechanical impedance of the researched area on the phase-frequency characteristics of the output signal of the converter, it is proposed to use as the diagnostic signs: the instantaneous frequency and the value of the phase characteristic of the current signal for certain points in time. The proposed informative features enable to increase general reliability of composite materials testing by the pulsed impedance method.
