Здоровье всегда являлось весомым капиталом человека, а грамотное распоряжением им всегда приносило ощутимые инвестиции. В современном мире с его темпами, задачами и вызовами у большинства людей все меньше времени остается на сохранение, поддержание и тем более укрепление здоровья. Но на возникающий запрос, формируется решение, продиктованное самим обществом, а именно, его цифровым отражением. Оцифровка общественной и личной жизни, несмотря на ее множественные недостатки, предоставляет огромные возможности, в том числе в отношении здоровья. Понятие цифровое здравоохранение включает в себя инструменты и технологии, повышающие эффективность оказания медицинской помощи, ее доступность и прозрачность. По данным всемирной организации здравоохранения (ВОЗ), цифровые технологии теперь являются неотъемлемой частью повседневной жизни людей, инновации, особенно в цифровой сфере, происходят в беспрецедентных масштабах. В 4 томе доклада Приоритет 2030 «Глобальный ландшафт исследований и перспективных разработок в области укрепления человека» рассмотрены и описаны зрелые, развивающиеся и фронтир технологии в имплантируемой и носимой электронике для модификаций возможности человека.

Development of the Dependability and Quality Assessment Method for the Design of Wireless Devices

2021 · CHAPTER · en

Automation of control methods of necessary requirements fulfilment or non-fulfilment while ensuring dependability and quality for wireless devices (WD) are necessary at design stages. However, this approach is not used in enterprises. Companies are limited only to expert assessment (non-automated external audit) and assessment of efficiency private criteria in the quality management system (QMS). The existing statistics of failures of radio engineering devices installed on unmanned automatic spacecraft indicates that there are shortcomings of ensuring the dependability and quality of the WD strategy. Therefore, in this paper, the method of dependability assessment of the WD considering the quality management system is proposed. The paper presents a mathematical model of dependability assessment of the WD considering not only the categories of the WD failures but also the private criteria contribution of the QMS functioning efficiency. Automation of the method is achieved by using the developed software.

Research of Mathematical Models for Assessing the Pumping Flashtubes Failure Rate

2021 · CHAPTER · en

The research provides a review and analysis of the existing mathematical model of the pumping flashtubes operational failure rate. They are used in various spheres of human activity, such as: industry (laser welding, balancing devices), medicine (laser devices, endoscopes, blood analyzers), photography (high-speed cameras). A computational assessment was carried out using a decision support system, which makes it possible to numerically determine the importance of the factors considered in the work in assessing the operational failure rate. As a result of the study, the main parameters have been determined that have the greatest impact on the pumping flashtubes dependability. Mathematical models considering these parameters have been identified. Reliable mathematical model is proposed, suitable for evaluating the dependability characteristics of pulsed pump lamps.

Models Analyses for Traveling Wave Tubes Failure Rate Estimating in the Design

2020 · CHAPTER · en

The work is devoted to the mathematical models study for operational failure rate estimating of traveling wave tubes. The detailed analysis of the parameters taken into account in the considered models is carried out. The key factors that have the greatest impact on the reliability characteristics are highlighted. Based on the results of numerical evaluation of the traveling wave tubes operational failure rate according to the considered mathematical models, a significant difference in the obtained results is shown. Mathematical models of operational failure rate, taking into account the key factors (temperature and manufacturing technology) based on the analysis of the causes of failure of traveling wave tubes are recommended to use. However, the considered mathematical models, in aggregate, do not take into account the key factors. This leads to an unreliable assessment of the reliability characteristics at the design stages

Hardware/Software Implementation of Simulation Modeling in the Tasks of Electronic Equipment Reliability Function Evaluating

2020 · CHAPTER · en

The paper presents a solution to the question of increasing authenticity and accuracy in predicting dependability, in particular, the reliability of electronic equipment (EE) by simulation modeling. A review and analysis of existing solutions is carried out and their drawbacks are identified. The description of the developed FPGA based VI-module is given, which allows to assess the EE reliability characteristics with an accuracy of 18 decimal places. Also, the developed VI-module is highly reliable due to the use of a random number generator with a repetition period depending on the type of FPGA up to 2^(64-1) in the form of hardware/software implementation based on FPGA.
