Opis:
Obecnie w niemal każdej dziedzinie życia zauważyć można znaczący wzrost znaczenia technologii. Rozwój ten jest konieczny i niesie za sobą wiele korzystnych zmian również w funkcjonowaniu nowoczesnego miasta, które w myśl współczesnych trendów ma stać się „SMART CITY”. Słownikowa definicja słowa „smart” wskazuje jego znaczenia jako „inteligentny, mądry”, co oznacza że „smart city” jest nie tylko inteligentne dzięki rozwiązaniom m.in. teleinformatycznym wspomagającym jego codzienne funkcjonowanie, ale także mądre mądrością korzystającą z dotychczasowych doświadczeń i odpowiadającą na nietechnologiczne potrzeby mieszkańców miast. Traktując współczesne technologie jako swoistą „nakładkę” na istniejącą lub projektowaną tkankę urbanistyczną należy pamiętać, że nowo projektowane obszary muszą być również „smart” swoją strukturą i programem tworzącym wysokiej jakości podbudowę pod miasto przyszłości.
We can currently observe a significant increase in the importance of technology in almost every aspect of life. This development is necessary and brings with it many beneficial changes, including those concerning the functioning of the modern city, which, according to contemporary trends, is to become a “SMART CITY”. The dictionary definition of the word “smart” points to its meaning as “intelligent, clever”, which means that a “smart city” is not only intelligent thanks to information technology-related solutions which support its day-to-day functioning, but also smart thanks to the wisdom of employing previous experiences and answering the non-technological needs of city residents. Treating contemporary technologies as a sort of “plug-in” for the existing or designed urban tissue, we must remember that newly designed areas should also be “smart” through their structure , as well as a programme that creates a high-quality foundation for the future city.

Opis:
The light-emitting diode (LED) is an essential component of intelligent street lighting (ISL) systems. An efficient ISL system can not only reduce power consumption by planning LED illuminating time but also reduce maintenance costs through a high degree of automation. In this paper, a buck-boost converter is used to realise composite transmission of power and signals for an ISL system. The power is modulated by the pulse width modulation (PWM) approach, and the switching ripple generated in the PWM process is utilised as the carrier of the signals transmitted between the remote-control centre and the slave nodes. Moreover, the proposed model involves a ‘request to send (RTS)/confirm to send (CTS)’ mechanism to avoid signal conflicts. Compared with the conventional power line communication (PLC) approach, the proposed transmission scheme has the advantages of simple circuit structure and simple system wiring. Additionally, a simulation model built in MATLAB/Simulink proves the designed transmission method has strong anti-noise ability.

Opis:
The electrical network is a man-made complex network that makes it difficult to monitor and control the power system with traditional monitoring devices. Traditional devices have some limitations in real-time synchronization monitoring which leads to unwanted behavior and causes new challenges in the operation and control of the power systems. A Phasor measurement unit (PMU) is an advanced metering device that provides an accurate real-time and synchronized measurement of the voltage and current waveforms of the buses in which the PMU devices are directly connected in the grid station. The device is connected to the busbars of the power grid in the electrical distribution and transmission systems and provides time-synchronized measurement with the help of the Global Positioning System (GPS). However, the implementation and maintenance cost of the device is not bearable for the electrical utilities. Therefore, in recent work, many optimization approaches have been developed to overcome optimal placement of PMU problems to reduce the overall cost by providing complete electrical network observability with a minimal number of PMUs. This research paper reviews the importance of PMU for the modern electrical power system, the architecture of PMU, the differences between PMU, micro-PMU, SCADA, and smart grid (SG) relation with PMU, the sinusoidal waveform, and its phasor representation, and finally a list of PMU applications. The applications of PMU are widely involved in the operation of power systems ranging from power system control and monitor, distribution grid control, load shedding control and analyses, and state estimation which shows the importance of PMU for the modern world.

This paper highlights the storage charging and discharging issue. The study objective is to manage the energy inputs and outputs of the principal grid at the same time in order to maximize profit while decreasing costs, as well as to ensure the availability of energy according to demand and the decisions to either save or search for energy. A fuzzy logic control model is applied in MATLAB Simulink to deal with the system’s uncertainties in scheduling the storage battery technology and the charging- discharging. The results proved that the fuzzy logic model has the potential to efficiently lower fluctuations and prolong the lifecycle.

Opis:
Transactive based control mechanism (TCM) needs the IoT environment to fully explore flexibility potential from the end-users to offer to involved actors of the smart energy system. On the other hand, many IoT based energy management systems are already available to a market. This paper presents an ap-proach to connect the current demand-driven (top-down) energy management system (EMS) with a market-driven (bottom-up) demand response program. To this end, this paper considers multi-agent system (MAS) to realize the approach and introduces the concept and standardize design of Agilometer. It is described as an elemental agent of the approach. Proposed by authors Agilometer consists of three different functional blocks, which are formulated as an IoT platform according to the LonWorks standard. Moreover, the paper also performs an evaluation study in order to validate the proposed concept and design.

Opis:
W artykule zaprezentowano wybrane wyniki realizowanego w Wojskowej Akademii Technicznej od 2013 r. projektu badawczego, którego celem jest wykonanie demonstratora technologii inteligentnego antypocisku służącego do zwalczania pocisków przeciwpancernych w ustalonej odległości od ochranianego obiektu. Przyjęto, że układem napędowym antypocisku będzie silnik rakietowy na paliwo stałe. W [1, 2] przedstawiono koncepcję oraz badania układu napędowego antypocisku dla przyszłościowego systemu ochrony aktywnej. W projektowanym układzie napędowym do zapalenia ładunku stałego paliwa rakietowego zostanie wykorzystany ładunek zapłonowy, w skład którego wchodzić będzie określona masa prochu czarnego. Ładunek ten będzie zamknięty w gnieździe znajdującym się w przednim dnie komory spalania. Pod wpływem gazów powstałych ze spalania ładunku zapłonowego nastąpi rozerwanie pokrywy zamykającej i uwolnienie (transfer) gazów zapłonowych do komory spalania. Z kolei zainicjowanie spalania prochu czarnego będzie dokonane wskutek impulsu cieplnego powstałego w wyniku przepływu prądu w zapłonniku elektrycznym (spłonce). W niniejszym artykule skoncentrowano się na analizach teoretycznych związanych z określeniem czasu trwania zapłonu paliwa rakietowego oraz czasem działania silnika rakietowego w kontekście wymaganych parametrów eksploatacyjnych antypocisku oraz na prezentacji wyników badań laboratoryjnego układu napędowego antypocisku polegających na obserwacji (wraz z rejestracją czasu) efektów działania układu: zapłonnik – ładunek prochu czarnego – ładunek paliwa rakietowego po podaniu impulsu prądowego na zapłonnik.
The paper presents indicative results of a research project carried out at the Military University of Technology (Warsaw, Poland), whose aim was to prepare a technology demonstrator of an active protection system against anti-armour missiles. One of the elements of this system is a smart counterprojectile designed to combat anti-tank missiles at a pre-determined distance from their intended target. The counter-projectile war-head includes electronic components sensitive to high launch loads. With this in mind, it was decided to use a solid propellant rocket motor as the propulsion system. The design concept of the counter-projectile and its propulsion system were developed on the basis of assessed requirements [1]. In the proposed propulsion system, a defined mass of black powder (ignition charge) ignites the solid rocket propellant. This ignition charge is enclosed in a pocket situated at the forward base of the combustion chamber. The igniter gases rupture the protective cover enabling the remaining gases to enter combustion chamber and ignite the main charge. The paper focuses on the theoretical analysis related to determining the duration of the ignition of rocket propellant and rocket motor operation time with regard to the required parameters. The paper presents the results of laboratory scale trials into the operation of the system: igniter – charge of black powder – a charge of solid rocket propellant after supply of an electrical pulse to the igniter.

Research background: With increasing evidence of cognitive technologies progressively integrating themselves at all levels of the manufacturing enterprises, there is an instrumental need for comprehending how cognitive manufacturing systems can provide increased value and precision in complex operational processes. Purpose of the article: In this research, prior findings were cumulated proving that cognitive manufacturing integrates artificial intelligence-based decision-making algorithms, real-time big data analytics, sustainable industrial value creation, and digitized mass production. Methods: Throughout April and June 2022, by employing Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, a quantitative literature review of ProQuest, Scopus, and the Web of Science databases was performed, with search terms including "cognitive Industrial Internet of Things", "cognitive automation", "cognitive manufacturing systems", "cognitively-enhanced machine", "cognitive technology-driven automation", "cognitive computing technologies", and "cognitive technologies". The Systematic Review Data Repository (SRDR) was leveraged, a software program for the collecting, processing, and analysis of data for our research. The quality of the selected scholarly sources was evaluated by harnessing the Mixed Method Appraisal Tool (MMAT). AMSTAR (Assessing the Methodological Quality of Systematic Reviews) deployed artificial intelligence and intelligent workflows, and Dedoose was used for mixed methods research. VOSviewer layout algorithms and Dimensions bibliometric mapping served as data visualization tools. Findings & value added: Cognitive manufacturing systems is developed on sustainable product lifecycle management, Internet of Things-based real-time production logistics, and deep learning-assisted smart process planning, optimizing value creation capabilities and artificial intelligence-based decision-making algorithms. Subsequent interest should be oriented to how predictive maintenance can assist in cognitive manufacturing by use of artificial intelligence-based decision-making algorithms, real-time big data analytics, sustainable industrial value creation, and digitized mass production.

Opis:
Presently, digitalization is causing continuous transformation of industrial processes. However, it does pose challenges like spatially contextualizing data from industrial processes. There are various methods for calculating and delivering real-time location data. Indoor positioning systems (IPS) are one such method, used to locate objects and people within buildings. They have the potential to improve digital industrial processes, but they are currently underutilized. In addition, augmented reality (AR) is a critical technology in today’s digital industrial transformation. This article aims to investigate the use of IPS and AR in manufacturing, the methodologies and technologies employed, the issues and limitations encountered, and identify future research opportunities. This study concludes that, while there have been many studies on IPS and navigation AR, there has been a dearth of research efforts in combining the two. Furthermore, because controlled environments may not expose users to the practical issues they may face, more research in a real-world manufacturing environment is required to produce more reliable and sustainable results.

Opis:
Intelligent transport systems (ITS) are undoubtedly an opportunity for the sustainable development of smart cities today. ITS is based on advanced transport technologies that help minimise the emission of harmful substances to the environment. Smart mobility and ITS are related to the use of ICT. The implementation of technologically advanced ITS is associated with several benefits, barriers and difficulties. However, transport, ITS and smart mobility (as a component of a smart city) are indicated as the most desirable option for sustainable urban transport systems. The article aims to identify barriers related to the implementation of ITS in cities from the point of view of people responsible for the organisation of urban transport representing the local government of selected voivodship cities in Poland. The goal formulated in this way allowed to identify the following research question: what are the problems and barriers of implementing ITS in the city from the local government’s perspective? To achieve the paper’s aim, the author based their analysis on a qualitative technique of collecting empirical data. Ten individual in-depth interviews were conducted with representatives of local governments (vice-mayors and members of urban transport organisers) in voivodship cities, which represented six Polish macro-regions. Research results and findings indicate the main categories and subcategories of barriers related to the ITS implementation. The identified barriers are grouped into the following categories: economic, social, organisational, technological and legal. The contribution is twofold: first, in the presentation of the theoretical and practical barriers to ITS in juxtaposition; and second, in identifying the intelligent transportation impact, which affects the provision of being a smarter city. The findings can positively influence as important factors for local governments to focus on intelligent transport.

Opis:
In a smart city environment, Intelligent Transportation System (ITS) enables the vehicle to generate and communicate messages for safety applications. There exists a challenge where the integrity of the message needs to be verified before passing it on to other vehicles. There should be a provision to motivate the honest vehicles who are reporting the true event messages. To achieve this, traffic regulations and event detections can be linked with blockchain technology. Any vehicle violating traffic rules will be issued with a penalty by executing the smart contract. In case any accident occurs, the vehicle nearby to the spot can immediately send the event message to Unmanned Aerial Vehicle (UAV). It will check for its credibility and proceed with rewards. The authenticity of the vehicle inside the smart city area is verified by registering itself with UAVs deployed near the city entrance. This is enabled to reduce the participation of unauthorized vehicles inside the city zone. The Secure Hash Algorithm (SHA256) and Elliptic Curve Digital Signature Algorithm (ECDSA-192) are used for communication. The result of computation time for certificate generation and vehicles involvement rate is presented.

Opis:
Smoke control solutions are used to maintain tenable conditions in buildings, enabling evacuation process, rescue operations and reducing the thermal stress on the building structure. For last 50-years the design process of such solutions did not significantly change – a required volumetric capacity is calculated with theoretical and empirical models, and further, mechanical design is prepared to deliver this capacity. In this paper, a new approach – “smart smoke control” is introduced, as a system that adapts the performance parameters based on the momentary measurements of temperature in the building. The system follows the growth and decay of fire in the building, which allows optimization of its mechanical parameters, and provides substantial increase in the performance. This paper provides a discussion on traditional and new concepts in smoke control, and defines areas, in which a paradigm shift must occur, to enable widespread adoption new and more efficient solutions. The paper does also refer to previous proof of concept studies, presenting the preliminary assessment of the performance of a smart smoke control system.
