Modelling, analysis and control design of hybrid dynamical systems

Abstract This paper introduces a methodology for one of the challenges regarding cyber-physical systems, ie modelling and control design them as hybrid systems. The proposed methodology comprises modules with specific steps to accomplish the tasks. Specifically, the paper aims to utilize hybrid systems framework onto the chosen hydraulic hybrid system with complex dynamics to showcase different aspects of hybrid systems. The mathematical model was derived using hybrid automata framework and then transformed into the linear form either using Jacobi matrices or using linear approximations without Jacobi matrices. After that the system was validated and analysed and the control design utilizing piecewise linear-quadratic regulator optimal control was proposed. Furthermore, parameters of control algorithm were tuned using particle swarm optimization algorithm. The whole logic, system dynamics and constrains are implemented within MATLAB/Simulink simulation environment using s -functions. The proposed methodology can be implemented on the various types of cyber-physical systems as far as they can be described as hybrid systems.
Language learning and inclusion in Italy

Abstract The study of inclusion models has regained attention in light of recent migratory phenomena. In this context, research in the area of second language (L2) teaching methodologies occupies a central role because it examines the most effective teaching approaches to promote the learning of a language that will be instrumental in the inclusion of the migrant For a definition of migrant see the European Migration Network (EMN) Glossary: “In the global context, a person who is outside the territory of the State of which they are nationals or citizens and who has resided in a foreign country for more than one year irrespective of the causes, voluntary or involuntary, and the means, regular or irregular, used to migrate”. https://ec.europa. eu/home-affairs/what-we-do/networks/european_migration_network/glossary_en (accessed April 7, 2018). in a new socio-cultural context. This work proposes some reflections on the bonds between language and cultural identity, with particular focus on the problematics related to culture shock. The premise is that language plays a key role as an instrument in inclusion because it allows the individual to understand a new reality and to make him or herself understood by others through a narrative process (storytelling). To promote the true inclusion of migrants into the fabric of the society of the adopted country, it is important to pursue a dual objective: to provide migrants with the instruments necessary for inclusion into the host society and, at the same time, educate the members of the host society as regards intercultural relationships. The purpose of this work is to furnish some research-based guidelines suitable to effective L2 teaching and present an example of an experience in the process of inclusion mediated through Italy’s works of art in museums.
Is Playing Soccer More Osteogenic for Females Before the Pubertal Spurt?

Abstract The aims of this study were to assess bone mass in children and adolescent soccer players and to evaluate the influence of both gender and pubertal status on bone mass. A total of 110 soccer players (75 males / 35 females; 12.73 ± 0.65 / 12.76 ± 0.59 years) participated in this cross-sectional study. They were divided into two groups according to their pubertal status. Bone and lean masses were measured with Dual-energy X-ray Absorptiometry. An independent t-test and an adjusted by subtotal lean and training experience multivariate analysis of covariance were used to analyse the differences in bone mass values between genders and maturity status. Female soccer players presented higher bone mass values than their male counterparts in most of the measured weight-bearing sites. Moreover, when stratifying by pubertal status, peripubertal and postpubertal females had higher subtotal body and lumbar spine bone mass than males. Comparing between pubertal status groups before adjustment, both male and female postpubertal players showed higher bone mass than their pubertal counterparts. After adjusting, these differences disappeared and, in fact results were inverted as bone mass at the femoral neck was higher in both male and female peripubertal soccer players than in postpubertal players. Bone mass seems to be more intensely stimulated by playing soccer in female than male players, particularly in the lumbar spine. The results of peripubertal players showing higher bone mass at the femoral neck after adjusting suggest that playing soccer during the peripubertal stage could be an effective activity to achieve optimal bone mass values.
Anthropometric and Motor Performance Variables Are Decisive Factors for The Selection of Junior National Female Volleyball Players

Abstract This study examined whether anthropometric and fitness tests might successfully predict selection of young female volleyball players for a junior national team. Sixty four female players (age: 14.4 ± 0.5 y, body height: 1.76 ± 0.05 m, body mass: 63.9 ± 6.4 kg) underwent a selection procedure for the junior national team. Anthropometric data and speed and power test results were obtained and players were graded for their performance in a volleyball tournament. Selected players differed from the non-qualified in body height (3.4%; p = 0.001), standing reach height (2.6%; p = 0.001), the sum of skinfolds (15.4%; p = 0.035), body mass index (BMI; 7.1%; p = 0.005) and spike jump and reach (SJR) (2.5%; p = 0.001). Selected players were classified in the 99.2 ± 1.6 percentile in body height and in the 51.4 ± 20.6 percentile in the BMI, which were significantly different from those of the non-qualified players (95.4 ± 7.0 and 66.7 ± 18.6, p = 0.02 and p = 0.004, respectively). Stepwise discriminant analysis yielded a discriminant function (p < 0.001, η2 = 0.78) that was highly loaded by height, SJR and the BMI (r = 0.79, r = 0.74 and r = -0.53, respectively). Cross validation results showed that selection was correctly predicted in 15 out of the 20 selected players (predictive accuracy: 75.0%) and in 35 out of the 44 non-qualified players (predictive accuracy: 79.5%). In conclusion, body height, the BMI and SJR height successfully discriminated between selected and non-qualified elite young female junior national team volleyball players. The equal vertical jump, sprint and agility of selected and non-qualified players, highlight the importance of body height and the BMI for selection of elite junior female volleyball players.
Could biodynamics help bridge the gap in developing farmer intuition?

Abstract Several scientific studies indicate that farmers do not often use formalised decision support tools as expected, and many prefer to rely on their intuition to make practical management decisions. While agricultural science and education acknowledge the different types of knowledge that farmers utilize, intuition continues to receive little attention in agricultural science, indicating a gap in farmer decision-making research. The mechanism driving intuition remains under debate, but is described as a pervasive, involuntary, rapid way of knowing, offering access to tacit (internal, intangible) knowledge that complements analytic processes. Many studies agree that intuition can be trained to increase accuracy and reliability. However, the comprehensive works on intuition by Rudolf Steiner hardly feature in modern science, and yet his writings and biodynamic agriculture approach offer farmers and non-farmers guidelines for systematic development of subtle abilities like intuition. There may be value in collaborative, transdisciplinary exploration between agricultural research and biodynamic theory and practice, for supporting farmers to develop their intuitive knowing. Such an alliance could help increase the awareness and practice of biodynamics, expand the knowledge base and lexicon for the em erging research field of intuitive farming, and help reinvigorate agricultural research toward more efficient, customized and connected farming practices.
Reinventing Organizations: Model of Self-Organized Process Organization (SOPO)

Abstract Background and Purpose: Self-organization in teams and Business Process Orientation have been subjects of many separate researches, yet there is lack of research actually joining it within a common research. The purpose of our research is to define a research model for new type of service organization - called SOPO (Self-Organised Process Organization). This model sets research base to determine SOPO’s maturity level and a self-assessment tool, helping new emergence or transitions of existing organization toward SOPO. Methodology: We conducted a case researches in three ICT service companies, which were undergoing a transition process towards SOPO. We conducted several in-depth, un-structured and structured part of interviews with employees holding three different positions in each organization. Hereby we present the researched organisation with most explicit case. Results: We defined the key elements of the model and tested it in a case research. Key elements are Self-Organised Work Teams (SOWT) and Business Process Orientation (BPO). Both SOWT and BPO are positively affecting level of SOPO. Level of SOPO is positively related to both, enthusiasm of personnel to work in self-organised environment and perceived Quality of Service (QS). Conclusion: SOPO model can be used: (1) in existing companies as a blueprint for SOPO implementation, (2) to assess the maturity level of companies reinventing their organizational structure, and (3) helping SOPO organizations to structure changes toward higher service quality. SOPO model is a viable starting point in further research. Further verification of the SOPO model by a quantitative research is needed.
What is wrong with false-link conditionals?

Abstract It is a common intuition that the antecedent of an indicative conditional should have something to do with its consequent, that they should be somehow connected. In fact, many conditionals sound unacceptable precisely because they seem to suggest a connection which is not there. Although the majority of semantic theories of conditionals treat this phenomenon as something pragmatic, for instance, something that is conversationally implicated, no one has offered a full-fledged pragmatic explanation of why missing-link, and, in particular, false-link conditionals strike us as odd. The aim of this paper is to explore the possibility that the link is an example of a conversational implicature. We discuss possible tests one can employ to identify conversational implicatures, and, ultimately, we show that the connection between a conditional’s antecedent and consequent fails them all.

Technical Assessment of Old Buildings by Fuzzy Approach

Abstract A group of old apartment houses with the age over 100 years (that is those carried out before the First World War) takes an important place in polish building resources. Technical maintenance of apartment houses, traditional methods erected, is nowadays and will be a valid problem in the nearest future. The results of the work refer to the general population, estimated for 600 objects, that is about 20% of municipal downtown apartment houses in Wrocław. The purpose of the research was to identify an influence of widely considered maintenance of apartment houses on a degree and intensity of their elements’ deterioration. The goal of the work has been fulfilled by symptoms’ analysis of declining of inspected elements’ exploitation values, that is identification of mechanics of their defects arising. The range of the work has required creation of original qualitative model of pinpointed defects and its transfer into quantitative one. It has made possible to analyse the reason - effect phenomena „defect - technical wear” relevant to the most important elements of Wroclaw downtown district’s apartment houses. The research procedure has been conducted in accordance of fuzzy sets theory which made possible to describe qualitative model of pinpointed defects and its transfer into a quantitative one.
Sewage sludge as a source of triclosan-resistant bacteria

Abstract Subinhibitory concentrations of antibiotics and biocides in wastewaters and sewage sludge have a great impact on the development of antibiotic resistance and its spread among bacteria. The aim of this work was to determine the occurrence of coliform bacteria and enterococci resistant to biocide triclosan in samples of sewage sludge. Subsequently, isolated strains of coliform bacteria were identified and characterized in terms of their antibiotic susceptibility and ability to form a biofilm. Occurrence of the studied bacteria was monitored in three samples of stabilized sludge from three different wastewater treatment plants (Vrakuňa, Petržalka, and Senec). The number of triclosan-resistant coliforms was the highest in the sludge sample from the wastewater treatment plant in Senec and the lowest in the sludge sample from the wastewater treatment plant in Petržalka. Triclosan-resistant Enterococcus spp. were not found in any sample of stabilized sludge. Most isolates were identified as Citrobacter freundii and Serratia spp. Triclosan-resistant isolates showed also resistance to antibiotics and the majority of them were strong biofilm producers.
Application of Tropospheric Sulfate Aerosol Emissions to Mitigate Meteorological Phenomena with Extremely High Daily Temperatures

Abstract This research examined whether tropospheric sulfate ion aerosols (SO42−) might be applied at a regional scale to mitigate meteorological phenomena with extremely high daily temperatures. The specific objectives of this work were: 1) to model the behaviour of SO42−aerosols in the troposphere and their influence on surface temperature and incident solar radiation, at a regional scale, using an appropriate online coupled mesoscale meteorology and chemistry model; 2) to determine the main engineering design parameters using tropospheric SO42−aerosols in order to artificially reduce the temperature and incoming radiation at surface during events of extremely high daily temperatures, and 3) to evaluate a preliminary technical proposal for the injection of regionally engineered tropospheric SO42−aerosols based on the integral anti-hail system of the Province of Mendoza. In order to accomplish these objectives, we used the Weather Research & Forecasting Model coupled with Chemistry (WRF/Chem) to model and evaluate the behaviour of tropospheric SO42−over the Province of Mendoza (Argentina) (PMA) on a clear sky day during a heat wave event occurred in January 2012. In addition, using WRF/Chem, we evaluated the potential reductions on surface temperature and incident shortwave radiation around the metropolitan area of Great Mendoza, PMA, based on an artificially designed aerosol layer and on observed meteorological parameters. The results demonstrated the ability of WRF/Chem to represent the behaviour of tropospheric SO42− aerosols at a regional scale and suggested that the inclusion of these aerosols in the atmosphere causes changes in the surface energy balance and, therefore, in the surface temperature and the regional atmospheric circulation. However, it became evident that, given the high rate of injection and the large amount of mass required for its practical implementation by means of the technology currently used by the anti-hail program, it is inefficient and energetically costly.
Irritable bowel syndrome – psychiatric issues

Abstract Introduction: Irritable bowel syndrome is a chronic gastrointestinal disease classified as a functional gastrointestinal disorder. It has been diagnosed on the basis of the so-called Rome IV criteria since 2016. The prevalence of IBS in the general population is about 10–20%, with most patients being women. The etiology of the syndrome is multifactorial and is associated with visceral sensory dysfunction, abnormalities of motor and secretory bowel function, a history of infectious diarrhea and abnormalities in gut microbiota, dysregulation of the brain–gut axis (the influence of the hypothalamic-pituitary-adrenal axis and sex hormones), genetic, psychosocial, and environmental factors, and the patient's personality traits. IBS patients may show differences in the structure and function of the brain when compared to healthy control individuals. Treatment of IBS involves the use of non-pharmacological interventions (psychotherapy, education, hypnotherapy, dietary modifications, regular physical activity) and pharmacotherapy (cholinolytic drugs, opioid receptor antagonists, tricyclic antidepressants, serotonin 5-HT3 receptor antagonists and 5-HT4 agonists). Aim: The aim of the authors of this work is to draw attention to certain psychiatric aspects of the irritable bowel syndrome. It meets the criteria for a somatization disorder. Somatization is an important psychological factor directly related to the severity of IBS. It is estimated that the prevalence of psychiatric disorders among IBS patients ranges from 40% to 90% and is higher than in the general population. Affective disorders and anxiety disorders are the most commonly diagnosed. Method: The article reviews the research and works available in the Google Scholar and PubMed databases combining the issue of IBS with psychiatric aspects, i.e. common for IBS and psychiatric disorders, etiopathogenesis, the concept of somatization in the context of IBS, and the coexistence of diseases and mental disorders with the irritable bowel syndrome. Conclusion: Further research is needed to determine the causes of comorbidity of IBS and mental disorders.
Language teachers’ perceptions of multilingualism and language teaching: The case of the postgraduate programme “LRM”

Abstract This paper explores the language views and practices of postgraduate student-teachers attending a distance-learning Master’s Programme of a Greek University, entitled “Language Education for Refugees and Migrants” (LRM). Teachers and professionals working with language learners in linguistically diverse contexts make up an interesting research sample in order to explore their perceptions and practices concerning bi/multilingualism and language learning. The study was conducted through an open-ended questionnaire, delivered and completed electronically by the student-teachers of two modules of the Programme (LRM 53: Language teaching for adult refugees and migrants and LRM54: Language teaching for children with refugee and migrant background) and included open-ended questions regarding their profile, their perceptions towards bi/multilingualism and translanguaging, language use in the school context, the first language and its relation to second language learning. Taking into account the students’ sample profile, the data can provide insights into the ways student-teachers view and deal with language diversity in their classrooms. Issues of attitudes and practices towards multilingualism and language teaching are discussed in relation to students-teachers’ professional development/education. Also, through comparisons between the two groups of students of the modules, the results are expected to explore some common ground assumptions on the differences between language teaching for children and adults (in the refugee context) but also potential nuances and elements of distinctiveness in the two areas.
Efficacy of Tolvaptan in Elderly Patients with Heart Failure and Preserved Ejection Fraction

Abstract Background: There is no known therapy with proven efficacy for improving clinical outcomes in elderly patients with heart failure (HF) and preserved ejection fraction (HFpEF). In this study, we aimed to evaluate the efficacy of tolvaptan (TLV) in elderly HFpEF patients. Methods: This retrospective observational study involved 100 consecutive elderly HFpEF patients hospitalized at the Nagoya Heart Center, Japan. Inclusion criteria were: (1) patients aged ≥75 years; (2) first hospitalization secondary to HF; (3) received medical therapy for HF, without invasive treatment; and (4) clinical follow-up for >6 months after discharge. The primary endpoint was rehospitalization due to worsening HF, and the secondary endpoint was worsening renal function (WRF) during hospitalization and at 6 months after discharge. Sixty background-matched HFpEF patients were divided into 2 groups: with TLV therapy (TLV (+), n = 29) and without TLV therapy (TLV (–), n = 31). In the TLV (+) group, TLV therapy was continued after discharge. Clinical outcomes of these patients were evaluated. Results: Bed rest period and length of hospital stay were significantly shorter in the TLV (+) group than in the TLV (−) group. The dose of loop diuretics, mean serum creatinine levels, and incidence of WRF development were significantly lower in the TLV (+) group. Incidence of rehospitalization was also significantly lower in the TLV (+) group (log-rank test; p = 0.018). The multivariate logistic regression analysis demonstrated that TLV therapy reduces the incidence of rehospitalization in elderly patients with HFpEF. Conclusions: TLV therapy reduced the bed rest period, length of hospital stay, and rate of rehospitalization without WRF in elderly HFpEF patients, suggesting that TLV could represent an effective therapy for this group of patients.
Reliability Test of a GNSS Onboard Receiver in the Kinematic Mode

Abstract The article presents the results of the aircraft Cessna 172 positioning based on navigation solutions in the GPS and EGNOS (SBAS) tracking mode. The article makes a comparison of coordinate readings of the Cessna 172 in the ellipsoidal BLh frame. The verification of the coordinates of the aircraft Cessna 172 was used to assess the reliability of the GNSS satellite technique in aviation. In a research test, the navigation data were recorded by the onboard receiver Thales Mobile Mapper during an air test performed over the military aerodrome EPDE in Dęblin. Judging by the conducted investigations, it is possible to conclude that the difference in BLh coordinates of the aircraft Cessna 172 on the basis of the GPS solution and EGNOS (SBAS) solution equals, respectively: from −0.5 m to +3 m for component B; and from −2 m to +6 m for component L; from approximately −11 m to over +1 m for component h. In addition, the paper defines factors of dilution of precision PDOP, based on the GPS and EGNOS (SBAS) solutions. The average value of the PDOP coefficient for a solution in the tracking GPS mode was 2.7, whereas in the EGNOS (SBAS) tracking mode, it was equal to 2.8.
