Carbon fibers have been technically applied in high performance materials and industrial scale applications. Importantly, carbon fiber reinforced composite materials have found applications in aerospace industries. These properties of carbon fiber reinforced composites depend upon the carbon fiber features such as length, orientation, surface properties, adhesion with matrices, etc. To improve the surface properties of carbon fibers and adhesion and interactions with polymers, fiber modification has been suggested as an efficient approach. Carbon nanoparticle or nanocarbon functionalized carbon fibers have been manufactured using various facile physical and chemical approaches such as electrospraying, electrophoretic deposition, chemical vapor deposition, etc. Consequently, the modified carbon fibers have nanocarbon nanoparticles such as graphene, carbon nanotube, nanodiamond, fullerene, and other nanocarbons deposited on the fiber surface. These nanocarbon nanoparticles have fine capability to improve interfacial linking of carbon fibers with the polymer matrices. The chemical vapor deposition has been adopted for uniform deposition of nanocarbon on carbon fibers and chemical methods involving physical or chemical modification have also been frequently used. The resulting advanced epoxy/carbon fiber/nanocarbon composites revealed improved tensile and physical profiles. This review basically aims manufacturing and technical aspects of polymer/fiber/nanofiller nanocomposites toward the development of high performance structures. The resulting morphology, strength, modulus, toughness, thermal stability, and other physical features of the nanocarbon functionalized carbon fibers have been enhanced. In addition, the fabricated polymer/fiber/nanofiller nanocomposites have fine interfacial adhesion, matrix-nanofiller-filler compatibility, and other characteristics. The application areas of these nanomaterials have been found wide ranging including the strengthened engineering structures, supercapacitors, shape memory materials, and several others.

Understanding the anomalies generated by various subsurface targets and their responses to different geophysical techniques in various subsoil types is critical to near-surface geophysical investigations. Geophysical test site (GTS) plays a vital role in near-surface geophysical investigations and related Earth sciences to adequately predict the geometries and anomalies generated by the subsurface targets. Therefore, developing a GTS on a site requires some technical efficiencies, mechanical procedures, engineering concepts and scientific approach, depending on the operating environment and the purpose of construction. This paper reviews the evolving roles of GTS in engineering, sciences, and technology via remarkable pedagogical and scientific research. The procedures for designing and installing GTS were also discussed. Every constructed GTS is unique and has its operating environment and sets of scientific requirements. As a result, the execution of GTS should be subjected to numerous factors that invariably affect the overall long time usage and performance. Comparative studies of GTS activities indicate that GTS is a vital geophysical research and academic platform to enrich the outcomes of the geophysical modelling for near-surface geophysical applications in engineering, science and technology. The evolving application of GTS has greatly impacted the field of science and engineering by enhancing the knowledge and understanding of the earth’s interior, which invariably affects the engineers, geophysicists, archaeologists and geologists to be critical in the analysis, interpretation, and providing precise and accurate information of subsurface anomalies underlying the uppermost soil of the earth’s crust. After a critical investigation, it was noted that the installation of GTSs is usually conceived to replicate situations often encountered in field investigation contexts. Examination shows that GTS can provide an ideal platform for young geoscientists, engineers and archaeologists to acquire the requisite skills, knowledge, technical know-how, and professional techniques for resolving near-surface challenges in real-life work situations. More also, a well-developed and equipped GTS could be a watershed in technological advancement, research development, and new scientific ideas. The GTS platform also indicates a promising pedagogical approach to geophysical educational usage, research mobilization, and development of new shallow geophysical techniques for various near-surface investigation and calibrating/testing geophysical equipment, which invariably catalyzed engineering designs, scientific concepts and technological advancement.

We consider purely singular homogeneous Young measures associated with elements of sequences of piecewise constant functions and with limits of such sequences. We first consider a case when the limit of a such sequence is piecewise constant. The next point involves the sequences of bounded oscillating functions, divergent in the strong topology in L ∞ , but weakly∗ convergent to a homogeneous Young measure. We also present an example of a fast oscillating sequence, illustrating the result. In the presented results, generalizing to some extent known examples, we try to avoid advanced methods of functional analysis that are usually used when solving problems of this type.

In this publication, we refer to a certain novelty introduced to the presentation at the AGU 2020 conference. This novelty consists of quoting the thoughts, remarks, and comments of six young people who declared their interest in space research after listening to a lecture on the Interstellar Probe journey, organized in June 2020 by the Polish Space Agency. Therefore, they were then asked to express their comments after reading two publications on the Interstellar Probe that were sent to them. As a result, this idea also became the topic of this article. Although the interstellar mission is primarily a research and science project, its engineering, logistics, business (economic), and social aspects, as well as a short commentary on our home in the universe, which is the heliosphere, have also been included in this article.

The article presents theoretical and practical aspects of the operation of a key engineering category, i.e. technical engineering, and its dominant influence on the level of technical and civilisational development in evolving societies. The introduction discusses the concept, role, and place of technical engineering, and the general methodological framework applied in it. It emphasises the strong links between the scientific theoretical foundations of technical engineering and engineering practice, which stem chiefly from societal needs and utilitarian passions of many researchers involved in the creative art of engineering. The following section presents technical and technological assumptions and practical achievements of selected categories of technical engineering, such as: civil, water, military, mechanical, electrical, process, materials, and extreme engineering. The article is a conceptual review and stresses the synergy between science, knowledge, and technology (mainly technical and applied), as well as competences and skills, against the background of utilitarian societal needs.

We present online mathematical tests for engineering students devised as a replacement of regular in-class exams. When the correctness of solution is being analysed the consequent steps are checked via various types of questions available on a platform: single choice, multiple choice, true-false, matching and finally embedded questions. When the correct answer is entered the relevant number of points is added to the final score, while when the student enters incorrect answer he loses a relevant number of points. The incorrect answers are diligently worked out based on typical errors performed by students during in-class exams. Tests consist of problems with diverse complexity due to the type of problems considered. Due to a considerable number of students and random selections of questions in each test, every single question in each test has many different versions.

Characterinsing the nature of cybephysical systems is not easy task. What are core aspects and what are not? This is especially tricky in systems-of-systems aggregates. Some EU-funded cyberphysical systems projects have performed a roadmapping exercise over the domain of Cyber-Physical Systems-of-Systems. In particlular, the EU-CPSoS project roadmap has identified three major challenges and eleven research and innovation policies that shall be addressed to solve the three challenges. The third core challenge addresses Cognitive Cyber-physical Systems of Systems. In this article we address the role that knowledge and cognition are to play in future cyber-physical systems of systems from a life-cycle perspective of high autonomy systems.

Content available On a certain embedding in the space of measures
EN
We take under consideration Young measures - objects that can be interpreted as generalized solutions of a class of certain nonconvex optimization problems arising among others in nonlinear elasticity or micromagnetics. They can be looked at from several points of view. We look at Young measures as at a class of weak* measurable, measure-valued mappings and consider the basic existence theorem for them. On the basis of this theorem, an imbedding of the set of bounded Borel functions into the set of Young measures is defined. Using the weak* denseness of the set of Young measures associated with simple functions in the set of Young measures, it is shown that this imbedding assigns the Young measure associated with any bounded Borel function.

We continue considerations concerning Young measures associated with bounded measurable functions from a recent article. We look at them as at the weak* measurable, measure-valued mappings. We show examples explaining that we cannot regard a Young measure (i.e. a weak* -measurable mapping) δu(x) as an explicit form of a Young measure associated with a function u. We also consider convergence of the sequences of Young measures.

Determining the competencies required for engineering programmes has become important due to the increasing challenges faced by engineers after graduation and the tremendous development in technology. This research aims to identify the general competencies that fresh graduate students of engineering schools in Jordan believe they need to become competent and effective in their profession as engineers. This study was the first of its kind with students as respondents, and it was the first study of this kind in Jordan. Competencies were collected from a previous study with 48 competencies split into 11 groups. A questionnaire was prepared with these competencies, then rated for the degree of importance by answering “What engineering competencies graduates will require for their future work in Jordan?” The study showed that all competencies were vital, including technical, personal, nontechnical and attitudinal competencies. This study will help to link the outputs of university education provided by engineering departments with market needs as well as to harmonise study programmes offered by Jordanian universities. Also, the research outputs are expected to facilitate the transition process of students from one university to another. The empirically identified competencies could be used to help assess different engineering study programmes in Jordan.

The article discusses the concept of mathematical education of pupils of a school and the results of pedagogical research. Being trained to solve the simplest tasks without a deep (thorough) understanding of the meaning of mathematical relationships is not conducive to the development of intellectual abilities and is quickly lost after completing the topic. It is experimentally confirmed that a student aspiring to attain a higher technical education, in addition to computational skills, needs to have an idea about mathematics and its methods, possess logical development, a graphic culture, develop a spatial imagination, independent work skills, the ability, if necessary, to use the appropriate directory to restore specific facts and obtain the necessary information. The research also looks into ways of solving problems with designing the learning environment and elaborating variable models of studying the natural and mathematical sciences with application of certain components of a computer-oriented learning system with the aim of upgrading pupils’ performance (a mass model, the main model and the creative model – an advanced level). The structuring of knowledge and the correct correlation of the selected types of knowledge develop the content of profile education, taking into account significant differentiation and the possibility of building an individual educational curriculum for schoolchildren, and also contributes to the filling of the three most important components of the content of profile training: basic invariant, profile variational and additional ones.

Omówiono koncepcję edukacji matematycznej uczniów szkoły oraz wyniki pedagogicznych badań naukowych. Wyćwiczenie w rozwiązywaniu najprostszych zadań bez głębszego (świadomego) rozumienia sensu zasad matematycznych nie sprzyja rozwojowi zdolności intelektualnych i jest szybko zapominane po zakończeniu przerobionego tematu. Uczeń zamierzający uzyskać wyższe wykształcenie techniczne oprócz nawyków obliczeniowych powinien zdobyć wiedzę o matematyce i jej metodach, osiągnąć rozwój logiczny, kulturę graficzną, rozwiniętą wyobraźnię przestrzenną, nawyki samodzielnej pracy, umiejętność pozwalającą, w koniecznym przypadku, skorzystać z odpowiedniego źródła w celu ustalenia konkretnych faktów i otrzymać niezbędne informacje. Strategia realizacji nauczania profilowanego przewiduje oddzielenie poziomu ogólnokształcącego od poziomu profilowanego. W badaniu zostały również omówione sposoby rozwiązania zadań projektowania środowiska uczenia się i tworzenia modeli z zastosowaniem poszczególnych składników komputerowo-zorientowanego systemu kształcenia w celu poprawy wyników uczniów. Przeprowadzona strukturyzacja wiedzy i prawidłowe zestawienie wydzielonych typów wiadomości pozwalają na opracowanie treści nauczania profilowego, zakładającego znaczne zróżnicowanie i możliwość ułożenia dla uczniów indywidualnego programu nauczania (model masowy, model podstawowy i model twórczy – wyższy). W badaniu biorą udział metodycy w celu przeprowadzenia eksperymentów w szkolnej praktyce dla określenia zdolności intelektualnych, rezultaty są również analizowane na podstawie badań eksperymentalnych.
