Opis:
In this article, an engineering/physical dynamic system including losses is analyzed inrelation to the stability from an engineer’s/physicist’s point of view. Firstly, conditions for a Hamiltonian to be an energy function, time independent or not, is explained herein. To analyze stability of engineering system, Lyapunov-like energy function, called residual energy function is used. The residual function may contain, apart from external energies, negative losses as well. This function includes the sum of potential and kinetic energies, which are special forms and ready-made (weak) Lyapunov functions, and loss of energies (positive and/or negative) of a system described in different forms using tensorial variables. As the Lypunov function, residual energy function is defined as Hamiltonian energy function plus loss of energies and then associated weak and strong stability are proved through the first time-derivative of residual energy function. It is demonstrated how the stability analysis can be performed using the residual energy functions in different formulations and in generalized motion space when available. This novel approach is applied to RLC circuit, AC equivalent circuit of Gunn diode oscillator for autonomous, and a coupled (electromechanical) example for nonautonomous case. In the nonautonomous case, the stability criteria can not be proven for one type of formulation, however, it can be proven in the other type formulation.

Opis:
Modelling, solution, control and even design of many ecological and engineering systems involve dealing with nonlinear partial differential equations of which analytic solutions are rarely available and numerical approach with or without linearization, or approximation is inevitable most of the time. In this paper the possibility of analysing such systems by using a fairly new method known as Differential Taylor (DT) Transform and its advantages are proved. The results obtained by this method are compared with the experimental results and shown to be within good agreement with them. It is emphasised that DT Transform is not effective for only filtration systems, but can also be used equally well for absorption, heat and mass transfer, convective diffusion and similar systems.

Opis:
Given the most competitive nature of global business environment, effective engineering innovation is a critical requirement for all levels of system lifecycle development. The society and community expectations have increased beyond environmental short term impacts to global long term sustainability approach. Sustainability and engineering competence skills are extremely important due to a general shortage of engineering talent and the need for mobility of highly trained professionals [1]. Engineering sustainable complex systems is extremely important in view of the general shortage of resources and talents. Engineers implement new technologies and processes to avoid the negative environmental, societal and economic impacts. Systems thinking help engineers and designers address sustainable development issues with a global focus using leadership and excellence. This paper introduces the Systems Engineering (SE) methodology for designing complex and more sustainable business and industrial solutions, with emphasis on engineering excellence and leadership as key drivers for business sustainability. The considerable advancements achieved in complex systems engineering indicate that the adaptation of sustainable SE to business needs can lead to highly sophisticated yet widely useable collaborative applications, which will ensure the sustainability of limited resources such as energy and clean water. The SE design approach proves critical in maintaining skills needed in future capable workforce. Two factors emerged to have the greatest impact on the competitiveness and sustainability of complex systems and these were: improving skills and performance in engineering and design, and adopting SE and human systems integration (HSI) methodology to support sustainability in systems development. Additionally, this paper provides a case study for the application of SE and HSI methodology for engineering sustainable and complex systems.

Opis:
Satellite hardware has reached a level of development that enables imaging satellites to realize applications in the area of meteorology and environmental monitoring. As the requirements in terms of feasibility and the actual profit achieved by satellite applications increase, we need to comprehensively consider the actual status, constraints, unpredictable information, and complicated requirements. The management of this complex information and the allocation of satellite resources to realize image acquisition have become essential for enhancing the efficiency of satellite instrumentation. In view of this, we designed a satellite auto mission planning system, which includes two sub-systems: the imaging satellite itself and the ground base, and these systems would then collaborate to process complicated missions: the satellite mainly focuses on mission planning and functions according to actual parameters, whereas the ground base provides auxiliary information, management, and control. Based on the requirements analysis, we have devised the application scenarios, main module, and key techniques. Comparison of the simulation results of the system, confirmed the feasibility and optimization efficiency of the system framework, which also stimulates new thinking for the method of monitoring environment and design of mission planning systems.

Opis:
Modeling and simulation are key performance analysis and control techniques to optimize decision-making as well as design and operate complex production systems. They are also indicated as one of the technological pillars of modern industry and IT solutions supporting the implementation of the roadmap toward Industry 4.0 in the areas of digital transformation and automation. In the context of the required rapid transformation of today’s enterprises, it becomes extremely important to look for solutions that allow the use of the existing infrastructure, information, and energy, so as to minimize the negative impact of new technologies and the transformation process itself on the environment. The article presents an approach to modeling large and complex production systems with the use of distributed Petri net models allowing the use of the possessed IT infrastructure as consistent with the idea of sustainable development in the activities of enterprises. This eliminates two major problems that render traditional models unusable. The first is related to the difficulties in analyzing and verifying models of enormous size and infinite space of states. The second is related to the required computing power, if such analyzes are to be performed on one computing unit, which would force the producers to replace the IT infrastructure. For this purpose, modular Petri nets are introduced. Other benefits of modularization, such as smaller components that can be independently analyzed, are also presented in the paper. The proposed modular Petri net has been implemented in the proprietary GPenSIM software. The paper is complemented by a practical example of industrial modeling of production systems with automated guided vehicles (AGVs) using the Modular Model with Intelligent Petri Modules.

Sformalizowane systemy zarządzania są we współczesnych organizacjach standardem. W zasadzie większość myślących konkurencyjnie organizacji co najmniej jeden taki system posiada wdrożony. Najczęściej posiadanym przez organizacje systemem jest system zarządzania jakością zgodny z ISO 9001. Mimo, że wiele organizacji posiada wdrożony taki system to jest jeszcze wiele takich, które dopiero planują takie wdrożenia. Niekiedy wdrożenie ISO 9001 jest wymagane przez klientów. Aby to umiejętnie zrobić wskazanym jest korzystać z doświadczeń innych organizacji. Uzasadnionym jest więc analizowanie przyczyn i korzyści wdrożeń systemu zarzadzania jakością. Taki też cel postawiono sobie w badaniach, których wyniki prezentuje to opracowanie. Dzięki znajomości wyciągniętych wniosków organizacje przygotowujące się do wdrożenia ISO 9001 będą mogły zrobić to w sposób umiejętny. Przyczyni to się z pewnością do lepszych ich wyników, co jest jednym celów wdrożenia wymagań normy ISO 9001.

Opis:
Many risks as a result of accidents, catastrophes and natural disasters can contribute to crisis situation, which according to the definition means a set of circumstances, both external and internal, that affect a given system through changes. Crisis situations are usually the result of natural disasters. Where such phenomena occur, it is important to ensure communication both at regional and national level. This is particularly important in areas affected by disasters caused by force majeure, such as earthquakes. The main aim of the article is to provide an overview of the architecture of contemporary information systems including satellite links, in order to present information on the potential possibilities of their use in the case of crisis situations.
Wiele zagrożeń wynikających z wypadków, katastrof czy klęsk żywiołowych może przyczynić się do powstania sytuacji kryzysowych, przez które zgodnie z definicją rozumie się zbiór okoliczności, zarówno zewnętrznych, jak i wewnętrznych, mających wpływ na dany system poprzez zaistniałe zmiany. Sytuacje kryzysowe są zazwyczaj wynikiem klęsk żywiołowych. W przypadku wystąpienia takich zjawisk ważne jest zapewnienie odpowiedniej komunikacji zarówno na poziomie regionalnym, jak i krajowym. Jest to szczególnie istotne na obszarach dotkniętych klęskami żywiołowymi spowodowanymi siłą wyższą, takimi jak trzęsienia ziemi. Głównym celem niniejszego artykułu jest przegląd architektury współczesnych systemów informacyjnych, z uwzględnieniem sieci satelitarnych, w celu przedstawienia informacji na temat potencjalnych możliwości ich wykorzystania na potrzeby komunikacji w sytuacjach kryzysowych.

A practical perspective is taken rather than a theoretical approach with experimentation reported on and possible future directions discussed. Applications of this technology are also considered with regard to both therapeutic use and for human enhancement. The culturing of neural tissue and its embodiment within a robot platform is also discussed, as are other implant possibilities such as permanent magnet implantation, EEG external electrode monitoring and deep brain stimulation. In each case the focus is on practical experimentation results that have been obtained as opposed to speculative assumptions.
