Opis:
W artykule przedstawiono badania odkształcalności słupa żelbetowego stanowiącego łącznik ścian prefabrykowanych. Elementy prefabrykowane, wykonane z modyfikowanej zaprawy Polytech zawierającej polistyren ekspandowany pochodzący z recyklingu, zastosowano do wykonania budynku mieszkalnego. Słupy żelbetowe w postaci łączników ścian w systemie Polytech są elementami nośnymi. W celu przeprowadzenia badań odkształceń słupa żelbetowego, będącego zarazem łącznikiem ścian prefabrykowanych w warunkach użytkowych, zastosowano innowacyjną technikę pomiaru odkształceń, polegającą na wprowadzeniu światłowodowych czujników odkształceń z siatkami Bragga. Metoda ta umożliwia ciągły pomiar odkształceń elementu podczas eksploatacji, co stanowi dużą zaletę systemu pomiarowego w odniesieniu do klasycznych systemów pomiarowych. Istotą rozwiązania jest wprowadzenie czujników światłowodowych FBG w strukturę konstrukcji żelbetowej. Zastosowanie metody pomiaru opartej na czujnikach z siatkami Bragga umożliwia również analizę bezpieczeństwa pracy elementu na etapie budowy i w trakcie użytkowania zrealizowanego obiektu. Przeprowadzone badania umożliwiły wyznaczanie rzeczywistego odkształcenia słupa żelbetowego po zamontowaniu w budynku modelowym oraz analizę pracy słupa podczas obciążeń normatywnych.
The paper presents technology of monitoring a reinforced concrete pillar-connector of prefabricated walls. Prefabricated units made from a modified Polytech mortar containing expanded polystyrene derived from recycling were used to build a residential object. Reinforced concrete pillars that serve as wall connectors in Polytech system are load-bearing elements. In order to control the reinforced concrete connector of prefabricated walls under realistic conditions, a control technology was applied that involved introducing fiber Bragg gratings deformation sensors. FBG monitoring method enables constant measurements of deformations of a construction element during its exploitation. This is a big advantage of the measuring system. The most important aspect of this solution are FBG sensors introduced into the reinforced concrete structure. The use of measuring method based on sensors with Bragg’s gratings allows constant analysis of operational safety of a given element both, in the construction phase and during the normal use of the building. Pillar reinforcement in the tested points did not deform identically. Localization of sensors in the controlled units is also important. Tests carried out by means of fiber optic sensors allow to determine the real scope of deformation of the monitored rebars used in the reinforced concrete pillar that is a connector of walls prefabricated in the Polytech system.

Opis:
The lack of proper analytical models of some production processes prevents us from obtaining proper values of process parameters by simply computing optimal values. Possible solutions of control problems in such areas of industrial processes can be found using certain methods from the domain of artificial intelligence: neural networks, fuzzy logic, expert systems, or evolutionary algorithms. Presented in this work, a solution to such a control problem is an alternative approach that combines control of the industrial process with learning based on production results. By formulating the main assumptions of the proposed methodology, decision processes of a human operator using his experience are taken into consideration. The researched model of using and gathering experience of human beings is designed with the contribution of agent technology. The presented solution of the control problem coincides with case-based reasoning (CBR) methodology.

Opis:
The paper refers to the evolution of methods, new technologies, and devices in security control processes in light of civil aviation requirements, procedures, and increased flow of passengers. The research problem has been defined as follows: How shall the international airport security controls function in the context of regulatory and operational conditions and current and future threats? In reference to the problem, the research hypothesis was defined as follows: Security control in civil aviation consists of screening persons and detecting prohibited articles and mainly depends on the professional competence of security staff and the proper selection and maintenance of electronic assistive devices. Professional competences refer to personnel’s knowledge, experience, qualification, monitoring, operational supervision, and quality control as part of their tasks. The development of new technologies requires the appropriate selection, commensurate with risk analysis, of electronic assistive devices, including equipment, methods, technical means, and their maintenance in a proper technical condition. The paper presents the results of empirical research conducted amongst experienced aviation security forums. Because of its complexity and unpredictability, this problem still leaves a wide margin for improvement and efficiency. The following research methods were used to solve the research problem: theoretical methods and empirical methods: diagnostic survey and expert interview.

Tekst dotyczy relacji między kontrolą społeczną a technologią. Związek ten analizowany jest na przykładzie jednego wybranego obszaru życia społecznego – sportu. Pole to stanowi bowiem miejsce niezwykle wyraźnie ukazujące dynamikę jego przemian. Na podstawie wybranych przykładów Autor poszukuje odpowiedzi na dwa główne pytania badawcze: kto dziś kontroluje technologię w świecie sportu i jak się ją kontroluje. Artykuł opiera się na badaniach empirycznych zrealizowanych w środowisku sportowym. Wykorzystuje on metodę case study. W jej ramach zastosowane zostały trzy techniki – desk research, analiza dyskursu medialnego oraz eksperckie wywiady jakościowe.
The paper concerns the relations between social control and technology. This phenomenon is illustrated by examples from a sport field. The sport remains a great indicator of social and technological changes, so it serves as an useful research context. The text analyses the three occurrences from nowadays sport world: legless athlete Oscar Pistorius and his artificial limbs; “shark skin” swimsuits; Frank Lampard’s disallowed goal in World Cup 2010. The cases lead to the two main questions. The first one is as follows: who (should) control technology in sport? The second one – how the technology should be controlled? The basis of this paper is an empirical research. The survey was conducted in sport environment. It uses the case study method. Within the method three minor technics were used: desk research, discourse analysis and expert’s IDI.

Opis:
Self-propelled wheelchairs favour the rehabilitation process, forcing the user to be physically active. Unfortunately, in most cases, the manual propulsion is not adapted to the individual needs and physical capabilities of the user. This paper presents the results of operational tests of a wheelchair equipped with a hybrid propulsion system in which the muscle strength generated by the user is assisted by two independent electric motors. The research aimed to investigate the influence of the applied control algorithm and the assistance factor (W) on the value of the muscular effort (MA) while propelling the wheelchair with the use of push rims. A modified ARmedical AR-405 wheelchair equipped with two MagicPie 5 electric motors built into the wheelchair’s hubs with a power of 500 W was used in this research. The tests were carried out on a wheelchair test bench simulating the moment of resistance within the range of 8–11 Nm. Surface electromyography was employed for the measurement of MA, specifically, a four-channel Noraxon Mini DTS apparatus. The research was carried out on five patients from the group of C50 anthropometric dimensions. The effort was measured for four muscles: deltoid–anterior part, deltoid–posteriori part, and triceps brachii and extensor carpi radialis longus. The effectiveness of the hybrid propulsion system was observed based on the extensor carpi radialis longus muscle. In this case, for the standard wheelchair, the MA ranged from 93% to 123%. In contrast, for a wheelchair equipped with the hybrid propulsion system, at W = 70%, the MA was within the range of 43%–75%.

Opis:
According to the requirements of green mine construction and the coordinated development of environmental protection regulations, the existing filling technologies in China are compared and analysed. Several types of technologies are discussed, including the dry filling technology for gangue, grouting and filling for separated strata zones in overburden, grouting and filling technology for caving gangue fissures, paste and paste-like filling, high-water and ultra-high-water filling, and continuous mining and continuous filling. Then, the characteristics of these individual technologies are analysed. Through the analysis and comparison of these technologies, considering the requirements of green mine construction and coordinated development of environmental protection regulations, it was found that continuous mining and continuous filling technology is a feasible mean for constructing green mines and protecting the environment. In this study, the application of continuous mining and continuous filling technology in the Yuxing coal mine is introduced. Results show that surface subsidence was less than 80 mm, and the recovery rate of the working face reached 95%. This indicates that continuous mining and continuous filling technology can solve the problems of surface subsidence, environmental damage, and coal resource waste. Finally, the development prospects of continuous mining and continuous filling technology are proposed, providing theoretical and technical support for similar mining.

Opis:
This paper is dedicated to an overview of components of an onboard control system of an autonomous ship. This system controls and operates the ship. Therefore, this system needs to be able to analyze the ship’s state, predict its future development and analyze the consequences of its own decisions. The paper focuses on software aspects of the onboard control system, not the hardware. The paper provides an overview of technologies that can be used to implement the components of such a system responsible for planning new routes, handling the ship during the voyage, ensuring its seaworthiness and safety during the voyage, monitoring an autonomous ship from an onshore control centre, ensuring the robustness of the onboard control system, and collective operations of multiple autonomous ships. The paper describes benefits the maritime industry would gain from deploying some of the technologies developed for autonomous ships on ordinary, human-controlled ships. The paper also describes some challenges, especially in the field of automatic decision and reasoning, arising from the emergence of autonomous and smart ships. The main contribution of the paper is that it summarizes existing research in different areas of autonomous ship technology.
