Optimal System of 1-D Subalgebras and Conserved Quantities of A Nonlinear Wave Equation in Three Dimensions Arising in Engineering Physics
Authors: Adeyemo Oke Davies , Khalique Chaudry Masood 
Published: July 2024

Abstract
The construction of explicit structures of conserved vectors plays diverse crucial roles in the study of nonlinear science inclusive of the fact that they are invoked in developing appropriate numerical schemes and for other mathematical analyses. Therefore, in this paper, we examine the conserved quantities of a nonlinear wave equation, existing in three dimensions, and highlight their applications in physical sciences. The robust technique of the Lie group theory of differential equations (DEs) is invoked to achieve analytic solutions to the equation. This technique is used in a systematic way to generate the Lie point symmetries of the equation under study. Consequently, an optimal system of one-dimensional (1-D) Lie subalgebras related to the equation is obtained. Thereafter, we engage the formal Lagrangian of the nonlinear wave equation in conjunction with various gained subalgebras to construct conservation laws of the equation under study using Ibragimov’s theorem for conserved vectors.
Reduced Gain PI/PID Controllers for FOPTD/SOPTD Processes Under Load Disturbance
Authors: Bożek Andrzej , Trybus Leszek 
Published: July 2024

Abstract
In practical applications, an engineer is sometimes expected to execute the step test for tuning the controller without waiting much for the steady-state or a low level of disturbances. Hence, knowing that the initial settings may not be quite reliable, he/she detunes the controller by reducing its gain as a precaution against possible poor behaviour of the closed-loop system. It is up to their experience to choose by how much to detune. Therefore, the development of a practically oriented approach that would assist the engineer to choose the degree of gain reduction is the goal of this paper. The approach assumes that process parameters are determined by the least-squares approximation of the step response. Accuracy of the approximation is evaluated by a relative approximation error involving integrals of the error and the process response itself. The SIMC tuning rules are applied to choose the initial controller settings. The approach relies on detecting by simulation the worst case that may happen when the step response is triggered at any time. Detuning nomograms specify by how much to reduce the initial gain for PI-FOPTD and PID-SOPTD designs, given the relative approximation error. Two long-lasting lab experiments involving temperature control identify a plant, verify the load disturbance model through multiple step tests and demonstrate usage of the approach in the closed-loop system.

Published: July 2024

Abstract
This work presents experimental and numerical studies of heat transfer during cooling fluid flow in a group of five minichannels 1 mm deep. The main purpose was to determine the heat transfer coefficient on the contact surface between the fluid and the heated wall of the selected minichannel at subcooled boiling. The temperature distribution on the outer surface of the heated plate was measured by means of an infrared camera. Thermal and flow parameters were monitored by an appropriate data-acquisition system. The test section was placed horizontally with fluid flowing above the heated wall. The HFE-649, HFE-7100 and HFE-7200 working fluids were examined in the experiments. Simcenter STAR-CCM+ software was used for numerical analysis of heat transfer in the test section. Furthermore, a simplified two-dimensional (2D) model was proposed that designates subcooled boiling heat transfer during fluid flow in a central minichannel. The heat-transfer process in the heated plate and the working fluid was described using indicated partial differential equations with appropriate boundary conditions. The solution to the proposed system of equations led to the solving of two more inverse Cauchy-type problems. The classical Trefftz method (TM) and the homotopy perturbation method (HPM) combined with the TM allowed for obtaining temperature distributions in the heater and the fluid and consequently, the heat transfer coefficient at the heater–fluid interface from the Robin boundary condition. Comparison of the results from numerical simulation due to Simcenter STAR-CCM+ showed similar temperature distributions at the heated surface. The calculated heat transfer coefficients, by HPM and Simcenter STAR-CCM+, were validated using the 1D approach. Furthermore, the results from simulations in Simcenter STAR-CCM+ in the form of local temperatures of the heater were confronted with experimental data for comparison. Similar results were achieved.
Thermal Stresses in A Multi-Layered Spherical Tank with a Slowly Graded Structure
Authors: Kulchytsky-Zhyhailo Roman 
Published: July 2024

Abstract
The central-symmetrical problem of thermoelasticity for a multi-layered spherical tank is considered. The thermal stresses were caused by a temperature difference between the inner and outer surfaces of the tank. Two approaches to solving this problem have been proposed. In the first approach, the boundary problem defined in the components of a considered inhomogeneous spherical tank was solved. In the second approach, the homogenization method with microlocal parameters was used. Good agreement between the solutions was obtained.

Abstract
The use of nanoparticle-infused blended refrigerants is essential for achieving an effective sustainable system. This investigation analyses the efficiency of three nano-refrigerants (CuO-R152a, TiO2-R152a and TiO2-R113a) on the basis of the thermal performance and energy usage of the compressor using MATLAB-Simulink in the vapour compression refrigeration cycle with a two-phase flow domain. Also, nanoparticle volume concentrations of 0.1%–0.5% in the basic refrigerants are investigated. In the Simulink model, the outcomes are calculated mathematically. Using the NIST chemistry webbook, the thermo-physical characteristics of base refrigerants were calculated, and different numerical models were used to compute the characteristics of nano-enhanced refrigerants. MS Excel was used to perform the liquid–vapour interpolation. It was discovered that refrigerants with nanoparticles have superior heat-transfer properties and operate most excellently at an optimal volume fraction of 0.1% for TiO2-R152a and CuO-R152a with a coefficient of performance (COP) as 10.8. However, the other blended nano-refrigerant TiO2-R113a performed the best at 0.5% of nano-particle volume fraction with a COP value of 5.27.

Abstract
In a world in which biometric systems are used more and more often within our surroundings while the number of publications related to this topic grows, the issue of access to databases containing information that can be used by creators of such systems becomes important. These types of databases, compiled as a result of research conducted by leading centres, are made available to people who are interested in them. However, the potential combination of data from different centres may be problematic. The aim of the present work is the verification of whether the utilisation of the same research procedure in studies carried out on research groups having similar characteristics but at two different centres will result in databases that may be used to recognise a person based on Ground Reaction Forces (GRF). Studies conducted for the needs of this paper were performed at the Bialystok University of Technology (BUT) and Lublin University of Technology (LUT). In all, the study sample consisted of 366 people allowing the recording of 6,198 human gait cycles. Based on obtained GRF data, a set of features describing human gait was compiled which was then used to test a system’s ability to identify a person on its basis. The obtained percentage of correct identifications, 99.46% for BUT, 100% for LUT and 99.5% for a mixed set of data demonstrates a very high quality of features and algorithms utilised for classification. A more detailed analysis of erroneous classifications has shown that mistakes occur most often between people who were tested at the same laboratory. Completed statistical analysis of select attributes revealed that there are statistically significant differences between values attained at different laboratories.
Beyond Volatility: Harnessing VUCA Methodology for Sustainable Collaboration in Bintan Island’s Mangrove Ecotourism Governance

Published: July 2024

Abstract
Collaborative Governance has emerged as a critical strategy for achieving public goals through collaboration with diverse organizations and individuals. The policy process requires the participation of various public institutions, with stakeholders directly or indirectly involved in addressing societal problems. In developing countries such as Indonesia, the power of stakeholders in implementing existing programs is critical to the success of collaborative governance. Indonesia has adopted an ecotourism strategy emphasizing sustainable practices, while the tourism industry emphasizes environmental preservation. Bintan Island is an attractive location for ecotourism activities due to its many prospective tourist destinations, ranging from land to sea, including mangrove forests in the coastal area. Due to its proximity to the Indonesia-Singapore-Malaysia border, the island has tremendous economic value for the local community. However, our research shows that the current situation regarding stakeholder participation in collaborative governance shows a weak correlation between actors. Significant gaps in collaborative governance dimensions and indicators must be addressed during the VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) period. In particular, many stakeholders lack the knowledge and understanding to engage interested parties and foster positive social interactions. To address this shortcoming, we propose to adopt the VUCA methodology as an alternative evaluation method for collaborative stakeholder-based governance. By doing so, we can integrate a more dynamic and adaptable framework to better adapt to rapidly changing socio-economic conditions.
Is There Basic A Priori Knowledge of Necessary Truth?
Authors: Wright Crispin 
Published: July 2024

Abstract
Following Kant, Frege took the idea that there is such a thing as bona fide a priori knowledge of a large range of necessary propositions for granted. In particular he assumed that such is the character of our knowledge of basic logic and arithmetic. This view is no longer orthodoxy. The idea that pure (for Frege, logical) intellection can provide for substantial knowledge of necessary features of the world is widely regarded with suspicion. However it is fair to say that most recent scepticism about it has been driven either by abstract background theoretical commitments—for instance, by a thoroughgoing empiricism, as in Mill and Quine, or by epistemological externalism1—or by the conviction that the concept of a priori justification allows of no stable, theoretically interesting characterisation.2 The present discussion focuses on the example of elementary arithmetic to develop and explore a different, relatively neglected and, it may be suggested, more fundamental kind of sceptical challenge, one prefigured in the writings on mathematics of the later Wittgenstein but independent of the discussion of following a rule to which his generally deflationary or conventionalist cast of thinking about mathematical knowledge is, after Kripkenstein,3 nowadays usually attributed. Elementary arithmetical truths are normally taken to be justifiable a priori if any truths are. They are also normally taken to be both necessary and substantial—essentially applicable to our dealings with the world and empirically predictive, yet good for counterfactual reasoning about however far-fetched and exotic scenarios. Yet, I will argue, scrutiny of the kind of methods—simple informal cognitive routines involving counting and pictures—whereby such judgements are initially apt to win our confidence serves to make it puzzling how they can justify what they are supposed to at all: how such procedures can merit either the very high levels of confidence we standardly place in the judgements they lead to, or the modal (counterfactual) significance we standardly attach to those judgements. The present discussion elaborates these apparent shortfalls (§§2–4) and reviews four proposals (§§5–8) for redressing them, arguing that each is ineffective. The sceptical challenge accordingly stands unanswered. §9 elaborates its relation to one strand in the Remarks on the Foundations of Mathematics. §10 summarises the resulting dialectical position. The upshot, I believe, is a deepened understanding of an important aspect of Wittgenstein’s later philosophy and a major intellectual challenge to those—possibly still a majority—who incline to side with Frege’s view of the epistemological status of arithmetic.
Movement refrains of people with visual impairments: A post-phenomenological geography beyond space and place
Authors: Pospíšilová Lucie , Doboš Pavel , Osman Robert 
Published: July 2024

Abstract
The paper intervenes in current discussions within post-phenomenological geography. It analyzes the movement of people with visual impairments in order to develop an approach to post-phenomenology that emphasizes the in-betweenness of bodies in motion. Our perspective differs from phenomenological (and humanistic) geographies and from post-phenomenological geographies that are rooted in object-oriented ontology. They both rely on the differentiation between space and place, accept pointillism, treat places as points in space, time as exclusively chronological, and bodies as beings, not becomings. We analyze data from interviews with people with visual impairments. We first consider their movement through the perspective of humanistic (particularly phenomenological) geography. After acknowledging the limits of this approach, we turn to our actualized conception of post-phenomenological geography, which draws on Deleuze’s concepts of movement, path, refrain, and involuntary memory. With this conceptual repertoire, we go beyond the space-place dichotomy and highlight the in-betweenness and virtuality of movement. We explore difference-producing repetitions, which are constituted through refraining into paths. Our approach conceptualizing movement as “refraining into paths” is instrumental to studying the movement of people with visual impairment: It helps to dispute ableism, and it enriches the current discussion about post-phenomenological geography in its insistence on relations and becoming.
Are Roma losing their roots? Traditional and non-traditional Roma occupations in two large communities in Romania: Timișoara and Cluj-Napoca

Published: July 2024

Abstract
In Romania, one of the countries with the largest Roma community in Europe, the gap between the majority population and the Roma minority continues to be wide. The paper explores whether there is a sustainability of traditional Roma occupations and crafts or whether we are witnessing a continuous occupational dynamic. The objective of the research is to identify the patterns of traditional and non-traditional economic activities practised in Roma communities in two cities: Timişoara and Cluj-Napoca. The research hypothesis investigates whether there is a wide range of economic activities in analyzed Roma communities, where traditional activities tend to have a negligible share and dynamics compared to non-traditional ones. Also, we analyze whether traditional activities remain relevant in Roma communities and whether they represent a significant occupational resource in the case of external migration. The following statistical hypotheses are presented: there are significant differences between members of Roma communities in Timisoara and Cluj-Napoca. These are observed in the choice of practising non-traditional-traditional economic activities in the country. There are significant differences between members of Roma communities in Timisoara and Cluj-Napoca in the practice of traditional versus non-traditional occupations according to ethnic subgroup membership.

Abstract
Botrytis is one the most economically important fungal taxa, comprising pathogens that infect a wide range of crops and causing gray mould. Two morphologically indistinguishable species, Botrytis cinerea and B. pseudocinerea, are significant pathogens found in close association in the same niches all over the world. Both species cause the same diseases in many plants; however, their mycelial compatibility in Latvia has not been reported. The aim of this study was to compare the morphological characteristics of B. cinerea and B. pseudocinerea isolates and determine their compatibility based on culturing on potato dextrose agar (PDA) media. A total of 113 isolates with the characteristic colony morphology of Botrytis spp. were obtained from four different host plants: tomato (Solanum lycopersicum), faba bean (Vicia faba), strawberry (Fragaria × ananassa), and cranberry (Vaccinium macrocarpon). The obtained isolates were divided into ten groups based on their morphological traits and hosts, and representatives from each group were chosen for further analyses. Botrytis spp. were identified at the species level using the DNA sequences of three protein-coding genes (RPB2, DNA-dependent RNA polymerase II; HSP60, heat shock protein 60; and G3PDH, glyceraldehyde 3-phosphate dehydrogenase). All ten isolates (five B. cinerea and five B. pseudocinerea) were pathogenic on wounded leaves and stems of ten-week-old tomato plants, and the pathogen was re-isolated and identified to fulfill Koch’s postulates. A high degree of phenotypic diversity was observed between and within B. cinerea and B. pseudocinerea. Mycelial compatibility was found to vary depending on the species, particular isolate, and host plant. This is the first report of B. pseudocinerea as a causal agent of gray mould on tomatoes in the Baltic region.

Published: July 2024

Abstract
The present research aims to conduct an in-depth analysis of the degradation of Romania’s demographic situation, with a particular focus on the implications of the aging trend. The study aims to investigate how this demographic shift may lead, in the absence of reformation measures, to elevated levels of poverty, social exclusion, and dependency among the elderly population. The contributing factors to this phenomenon include migration patterns, negative natural population growth, and the increasing life expectancy of the population. These factors collectively result in a growing imbalance between the elderly and working-age populations. The repercussions of this demographic shift include heightened pension costs, increased public debt, exacerbated social inequalities, and a potential hinderance to economic growth.
