Usage of different CAD systems for engineers is a true reality, therefore it is very useful for a specialist to be able to use different programs. Modern graphic programs (AutoCAD, SolidEdge) do have many similar opportunities but they also contain some very specific dissimilarities. It is necessary to be able to use several of those programs however it could be a problem for a future engineer to be able to find enough time to be able to get familiar with all CAD programs out there. In the article are compare functions of two different graphic programs and look at the possibility of usage both CAD systems to work with drawings.

In speaking of modern higher education, we mean an educational system that allows young specialists to fit into the labour market. Such specialists need to be equipped with the necessary knowledge and skills not only to perform work on the project, but also to attack the problem creatively. The task of higher school is to provide the necessary set of knowledge and skills that will allow young specialists to work successfully and to be on the march. The language of communication of engineers is drawings. Computer drawings allow reducing the working time considerably in the development, production, remediation, transfer, and retention. Therefore, the ability to use drawing program for working with images is necessary. Despite all the powerful design tools and visualization, a key moment in computer design is the documentation of the product and its design in accordance with accepted standards that is considered to be an integral part of the design process. After the successful development of a 2D environment, the expert can confidently move on to 3D modeling that facilitates the receipt of drawings and models at times and gives you the opportunity to inspect the settings of the virtual model and, if necessary, to improve them significantly. Usage of different CAD-systems for communication engineers- partners is a reality. Therefore it is very useful for a specialist to be able to use different programs. Modern graphic programs (AutoCAD, SolidEdge) have many similar opportunities, but they also have some differences. Knowledge of several drawing programs is necessary and reduces the amount of time for the skills development for usage of each CAD-system is the problem of the future engineer. The article compares two different programs and the possibility of using the both CAD-systems for working with drawings.

The article considers applications of foreign CAD-systems in creating the challenging projects at domestic enterprises and design bureaus. As stated in the article "... presently, there is no domestic CAD-system that could completely replace such foreign products as NX, CATIA, Credo". Besides, due to international cooperation in creating the challenging projects (for example, the project to create a modern wide-body aircraft, proposed jointly with China), it makes sense to use the worldwide known and popular CAD systems (the aforementioned NX, CATIA, Credo). Therefore, in the foreseeable future, we will still have to use foreign software products. Of course, there always remains a question of the reliability of the results obtained. Actually, this question is always open regardless of what software product is used - domestic or foreign. This question has been haunting both developers and users of CAD systems for the last 30 to 40 years. But with using domestic systems, it is much easier to identify the cause of inaccurate results and correct the mathematical models used, the methods of numerical integration applied, and the solution of systems of nonlinear algebraic systems. Everything is much more complicated if we use a foreign software product. All advertising conversations that there is a tool to make the detected errors available to the developers, remain only conversations in the real world. It is easily understandable to domestic users, and, especially, to domestic developers of similar software products. The existing development rates and competition for potential buyers dictate a rigid framework of deadlines for releasing all new versions of the product and introducing the latest developments into commercial product, etc. As a result, the known errors migrate from version to version, and many users have accepted it long ago. Especially, this concerns the less popular tools rather than the most popular applications (modules) of a CAD system. For example, in CAD systems, the "Modeling" module where geometric models of designed parts and assembly units are created has been repeatedly crosschecked. But most of the errors are hidden in applications related to the design of parts from sheet material and to the pipeline design, as well as in applications related to the analysis of moving mechanisms and to the strength or gas dynamic analysis by the finite element method.The article gives a concrete example of a moving mechanism in the analysis of which an error was detected using the mathematical model of external influence (a source of speed) in the NX 10.0 system of Siemens.

The new algorithm of solving harmonic balance equations which used in electronic CAD systems is presented. The new algorithm is based on implementation to harmonic balance equations the ideas of model order reduction methods. This algorithm allows significantly reduce the size of memory for storing of model equations and reduce of computational costs.

Проведен анализ случаев возникновения тиристорного эффекта в СВЧ ИС, изготовленных по технологии SiGe БиКМОП, при воздействии ионизирующего излучения. Рассмотрены области СВЧ ИС, чувствительные к возникновению ТЭ, определены основные параметры тиристорных структур. Проведена апробация подхода к восстановлению параметров схемно-топологической радиационно-ориентированной модели тиристорной структуры для САПР. The paper analyzes ionizing radiation induced latchup in microwave SiGe BiCMOS integrated circuits (ICs). Critical parts of ICs sensitive to latchup have been identified and basic parameters of corresponding parasitic thyristor structures have been determined. An approach has been approved to the thyristor structure compact model parameters extraction procedure intended for use in CAD systems.

COVID-19 has brought not only fear and anxiety, but also legitimate restrictions of communication and consequential touch-deprivation in our daily lives. Couples’ relational wellbeing continues to be impacted by these COVID-19 related stressors. Protecting both personal and relational wellbeing is therefore particularly important at this time. Using a preventative intervention approach, the current paper argues the theoretical benefit of the Positive Massage programme and reports a qualitative analysis of stressed but healthy couples’ experience of engaging in the programme. Thirty-four participants completed 3 weekly classes and home-based practice of massage exchange. Data from an open text online questionnaire completed every week of the programme and again 3 weeks afterwards were analysed using thematic analysis. The identified themes included “holistic stress relief”, “relationship-promotion”, and “selves-care skill”. Couples perceived Positive Massage as an effective mutual support skill to relax and help one another by de-stressing, both emotionally and physically through verbal and nonverbal communication, creating gratitude, deeper connection and self-efficacy via quality time together and pleasurable touch. Theoretically and experientially, Positive Massage can be an effective preventative selves-care skill. Promoting the concept of selves-care and its practical application through Positive Massage would be beneficial for couples’ personal and relational wellbeing in a touch-deprived era.
