Opis:
This paper investigates the non-fragile event-triggered control of positive switched systems with random nonlinearities and controller perturbations. The random nonlinearities and controller perturbations are assumed to obey Bernoulli and Binomial sequence, respectively. A class of linear event-triggering conditions is introduced. A switched linear co-positive Lyapunov function is constructed for the systems. For the same probability with respect to nonlinearities and controller perturbations in each subsystem, a non-fragile controller of positive switched systems is designed in terms of linear programming. Then, the different probability case is considered and the corresponding non-fragile event-triggered control is explored. Finally, the effectiveness of theoretical findings is verified via two examples.

Opis:
Some Kharitonov-like robust Hurwitz stability criteria are established for a class of complex polynomial families with nonlinearly correlated perturbations. These results are extended to the polynomial matrix case and non-interval D-stability case. Applications of these results in testing of robust strict positive realness of real and complex interval transfer function families are also presented.

Opis:
In this research work, a twelve-term novel 5-D hyperchaotic Lorenz system with three quadratic nonlinearities has been derived by adding a feedback control to a ten-term 4-D hyperchaotic Lorenz system (Jia, 2007) with three quadratic nonlinearities. The 4-D hyperchaotic Lorenz system (Jia, 2007) has the Lyapunov exponents L1 = 0.3684,L2 = 0.2174,L3 = 0 and L4 =−12.9513, and the Kaplan-Yorke dimension of this 4-D system is found as DKY =3.0452. The 5-D novel hyperchaotic Lorenz system proposed in this work has the Lyapunov exponents L1 = 0.4195,L2 = 0.2430,L3 = 0.0145,L4 = 0 and L5 = −13.0405, and the Kaplan-Yorke dimension of this 5-D system is found as DKY =4.0159. Thus, the novel 5-D hyperchaotic Lorenz system has a maximal Lyapunov exponent (MLE), which is greater than the maximal Lyapunov exponent (MLE) of the 4-D hyperchaotic Lorenz system. The 5-D novel hyperchaotic Lorenz system has a unique equilibrium point at the origin, which is a saddle-point and hence unstable. Next, an adaptive controller is designed to stabilize the novel 5-D hyperchaotic Lorenz system with unknown system parameters. Moreover, an adaptive controller is designed to achieve global hyperchaos synchronization of the identical novel 5-D hyperchaotic Lorenz systems with unknown system parameters. Finally, an electronic circuit realization of the novel 5-D hyperchaotic Lorenz system using SPICE is described in detail to confirm the feasibility of the theoretical model.

Opis:
The article pertain to a case study research of social assistance processes in a social policy system of G. city. A main method of investigation was opened, unstandardized systematic interviews with social workers, political figures and administrators of the system. Social services in experiences of our respondents we have interpreted as games for uncertainty control. The games in perspectives of social workers and administrators of the system we understand as pedagogical environments for customers which in the processes of these interactional games shape many of the social, adaptive skills. Such skills enable customers institutional identity management and effective winning spheres of freedom from control. Behavioural strategies of social workers in institutional and organizational environment in relation to customers we conceptualize as exchange models of a “gift for power” above customers spheres of uncertainty control. Inefficiency of social assistance comes from incapacity of such aid to effectively exchange gifts for uncertainty control in daily situations for customers. The Institution of social services has many functional substitutes in social, political and economic environments which are much more effective. Second goal of our investigation was a presentation and portrayal of the real pedagogical environment of social workers. Theory of social intervention and social pedagogy suffers from too many abstracts from reality foundations, premises und presumptions. So social pedagogy as practical science needs also careful and diligent investigation of

Opis:
The article describes the impact of the economic crisis caused by the global COVID-19 pandemic on enterprises from the service outsourcing industry operating in 11 European countries. The following research objectives have been indicated: 1) learning the opinions of managers on the crisis and its impact on the company, 2) indicating positive and negative features of the economic situation related to the global pandemic, 3) the analysis of the financial situation during the pandemic. The methodology adopted in the research is based on the descriptive approach, using the case study analysis. For the purposes of the research, the structured interview questionnaire was used. The questions asked concerned the description of the specificity of the business, the company’s location, the impact of the economic crisis on the situation of enterprises, the description of the positive and negative impact of the crisis on the operation of enterprises. The area of interest covered the subjective opinions of managers on the existing economic situation, which is metaphorically compared to the black swan in the article. The research conducted in the companies from 11 European countries indicated that in the period of March-August 2020, due to the strong dependence of the sector on the automotive industry, the companies were affected by the crisis. The turnover and the number of employees decreased dramatically. The slow recovery of contractors from the crisis as well as the change in customer approach to staff employment have changed the operating conditions of the quality outsourcing sector companies. Flexible adaptation to customer requirements has brought about that all the analyzed companies recorded an increase in the sales of their services, counting on the further good prosperity of the industry.
W artykule opisano wpływ kryzysu gospodarczego wywołanego globalną pandemią COVID-19 na przedsiębiorstwa z branży outsourcingu usług działające w 11 krajach Europy. Wskazano na następujące cele badawcze: 1) poznanie opinii menedżerów na temat kryzysu i jego wpływu na firmę, 2) wskazanie pozytywnych i negatywnych cech sytuacji gospodarczej związanej z pandemią światową, 3) analiza sytuacji finansowej podczas pandemii. Metodologia przyjęta w badaniu opiera się na podejściu opisowym, wykorzystując analizę studium przypadku. Na potrzeby badań wykorzystano ustrukturyzowany kwestionariusz wywiadu. Zadawane pytania dotyczyły opisu specyfiki działalności, lokalizacji firmy, wpływu kryzysu gospodarczego na sytuację przedsiębiorstw, opisu pozytywnego i negatywnego wpływu kryzysu na działalność przedsiębiorstw. W obszarze zainteresowania znalazły się subiektywne opinie menedżerów na temat istniejącej sytuacji gospodarczej, którą w artykule porównano metaforycznie do czarnego łabędzia. Badania przeprowadzone w firmach z 11 krajów europejskich wskazały, że w okresie marzec-sierpień 2020 r., ze względu na silne uzależnienie sektora od branży motoryzacyjnej, firmy zostały dotknięte kryzysem. Obroty i liczba pracowników drastycznie spadły. Powolne wychodzenie kontrahentów z kryzysu, a także zmiana podejścia klientów do zatrudniania pracowników zmieniły warunki działania firm z sektora outsourcingu wysokiej jakości. Elastyczne dostosowywanie się do wymagań klientów sprawiło, że wszystkie analizowane firmy odnotowały wzrost sprzedaży swoich usług, licząc na dalszą dobrą koniunkturę branży.

Opis:
The paper introduces a method of mathematical modeling of high scale road traffic networks, where a new special hypermatrix structure is intended to be used. The structure describes the inner-inner, inner-outer and outer-outer relations, and laws of a network area. The research examines the nonlinear equation system. The analysed model can be applied to the testing and planning of large-scale road traffic networks and the regulation of traffic systems. The elaborated model is in state space form, where the states are vehicle densities on a particular lane and the dynamics are described by a nonlinear state constrained positive system. This model can be used directly for simulation and analysis and as a starting point for investigating various control strategies. The stability of the traffic over the network can be analyzed by constructing a linear Lyapunov function and the associated theory. The model points out that in intersection control one must take the traffic density values of both the input and the output sections into account. Generally, the control of any domain has to take the density of input and output sections into consideration.

Opis:
Background: Pet therapy could help individuals improve their emotions; and physical and mental health. It also could be effective in the treatment of pain, anxiety, depression, and fatigue. The aim of this study was to determine the effectiveness of pet therapy, concurrent with common medication on positive, negative, cognitive and motor symptoms of schizophrenia. Methods: This was a randomized control trial. Statistical population of the current study included all patients who were admitted to the Razi Psychiatric Center of Tehran and received a diagnosis of schizophrenia based on a clinical interview and DSM criteria by a psychiatrist. Thirty six patients were recruited using snowball sampling. Members of the experimental group were transported by a bus to that spot at 9 a.m on the planned days, in the company of the researcher and a nurse. Patients gave care of the rabbits (including feeding, tidying their cages, moving their cages) for 24 sessions of 90 minutes, three days per week during autumn 2016. The One-way covariance test was also used to evaluate effects of Pet therapy on positive, negative, cognitive and motor symptoms of schizophrenia. Results: finding indicated that considering scores of pre-test for positive, negative and cognitive symptoms, there is a significant difference between the two controls and experimental groups, respectively, (F = 17.04, p < 0.05), (F = 17.39, p < 0.05), (F = 152.12, p < 0.05). Conclusion: Pet therapy could be successfully applied by parents, psychologists and care givers of these patients. We suggest using pet therapy for treatment of other psychiatric disorders as well and preferably like dogs and cats.

Opis:
Self-forgiveness is a process in which emotions, thoughts, and behaviours towards oneself are changed from negative to neutral or positive. In this study, we examined affectivity and emotional control (of anger, depression, anxiety) as emotional factors promoting or discouraging self-forgiveness. We examined self-forgiveness among Polish adults (N = 380, Mage = 36.26). Respondents completed the Polish version of the Positive Affect Negative Affect Scale, the Courtauld Emotional Control Scale (CECS), and the self-forgiveness subscale of Touissant’s Forgiveness Scale. In our cross-sectional study, we tested the moderating role of emotional control in the relationship between affectivity and self-forgiveness. Our results showed that positive affect was positively correlated with self-forgiveness, whereas negative affect was inversely correlated with self-forgiveness. Additionally, emotional control (anger, depression) was negatively correlated with self-forgiveness. Finally, total control of emotions and control of anger were found to be buffers between negative affect and self-forgiveness, the effect of negative affect on self-forgiveness being weaker among individuals who were more anger-controlling. The obtained results are a prelude to further research into the relationship between affectivity and self-forgiveness.

The study examined the importance of cognitive (positive orientation, basic hope) and emotional (positive and negative affectivity, emotional control) variables for state and trait forgiveness. One hundred and thirty nine participants completed six inventories in Polish version: HFS (Thompson et al., 2005), TRIM (McCullough et al., 1998), P-Scale (Caprara et al., 2012), BHI-12 (Trzebiński & Zięba, 2003a), SUPIN (Polish version of PANAS; Watson, Clark, & Tellegen, 1988), CECS (Watson & Greer, 1983). Results showed that dispositional forgiveness (general and positive) was associated with cognitive and emotional predictors, whereas episodic forgiveness primarily with certain emotional variables. In addition, the results indicated that emotional predictors merely participate in the process of reducing unforgiveness, whereas cognitive and emotional variables were shown to be necessary for full forgiveness.

Opis:
In this paper the problem of vibration reduction is considered. Generally, mechanical vibrations occurring during the operation of a system are undesirable and may have a negative effect on its reliability. A finite element model of a single active blade is developed using the Abaqus software. This structure consists of a multi-layer glass-epoxy composite beam with an embedded macro fiber composite (MFC) piezoelectric actuator. For vibration control the use of a positive position feedback (PPF) controller is proposed. To include the PPF controller in the Abaqus software, a special subroutine is created. The developed control algorithm code makes it possible to solve an additional differential equation by the fourth order RungeKutta method. A numerical dynamic analysis is performed by the implicit procedure. The beam responses with and without controller activation are compared. The control subsystem model also includes the hysteresis phenomenon of the piezoelectric actuator. Numerical findings regarding the PPF controller’s effectiveness are verified experimentally.

Opis:
This paper presents a new approach to robust adaptive control, using fractional order systems as parallel feedforward in the adaptation loop. The problem is that adaptive control systems may diverge when confronted with finite sensor and actuator dynamics, or with parasitic disturbances. One of the classical robust adaptive control solutions to these problems makes use of parallel feedforward and simplified adaptive controllers based on the concept of positive realness. The proposed control scheme is based on the Almost Strictly Positive Realness (ASPR) property of the plant. We show that this condition implies also robust stability in the case of fractional order controllers. An application to Model Reference Adaptive Control (MRAC) with a fractional order adaptation rule is provided with an implementable algorithm. A simulation example of a SISO robust adaptive control system illustrates the advantages of the proposed method in the presence of disturbances and noise.

W artykule przedstawiono zagadnienia związane ze sposobami oznaczania stref robót drogowych oraz stanem technicznym zastosowanych znaków pionowych i urządzeń bezpieczeństwa ruchu drogowego. Wpływ na bezpieczeństwo, oprócz nieodpowiedniego umiejscowienia oznakowania, ma również jego odblaskowość oraz czytelność. Omawiane niespełnienie wymagań przedmiotowych cech wynika z nienależytego dbania o zapewnienie właściwych parametrów i stanu technicznego używanych znaków pionowych i urządzeń bezpieczeństwa ruchu drogowego do oznakowania tymczasowych organizacji ruchu oraz w całym okresie ich stosowania. W głównej części artykułu opisano inwentaryzację istniejącego oznakowania na drogach w czasie prowadzenia prac budowlanych oraz przeprowadzono analizę zastosowanej organizacji ruchu, stanu technicznego znaków drogowych i wpływu tych elementów na bezpieczeństwo użytkowników ruchu drogowego.
This paper deals with ways of signing of road works areas and the technical condition of signs and traffic safety devices, and the impact on safety, in addition to the incorrect location of the marking, and its retro-reflective and legibility. This non-compliance with the requirements of the characteristics in question results from care not being taken to ensure that the signs and safety devices used are in good working order and throughout the period of application of the temporary traffic organization. The main part of the paper describes the inventory of existing road markings during construction work and analyzes the traffic organization used, the state of the road signs and the impact of these elements on the safety of road users.
