This paper proposes a metaphysical framework for distinguishing between human and machine intelligence. It posits two identical deterministic worlds -- one comprising a human agent and the other a machine agent. These agents exhibit different information processing mechanisms despite their apparent sameness in a causal sense. Providing a conceptual modeling of their difference, this paper resolves what it calls “the vantage point problem” – namely, how to justify an omniscient perspective through which a determinist asserts determinism from within the supposedly deterministic universe.

ABSTRACT In this study, performances of Multiple Linear Regression and Automatic Linear Modelling are compared for different sample sizes and number of predictors. A comprehensive Monte Carlo simulation study was carried out for this purpose. Random numbers generated from multivariate normal distribution by using RNMVN function of IMSL library of Microsoft FORTRAN Developer Studio composed the material of this study. Results of the simulation study showed that the sample size and the number of predictors are the main factors that lead to produce different results. Although both methods gave very similar results especially when studied with large sample sizes (n≥100), the Automatic linear modelling is preferred for analyzing data sets due to its simplicity in analyzing data and interpreting the results, ability to present results visually and providing more detailed information especially studying large complex data sets. It will be beneficial to use the Automatic linear modelling especially in analyzing massive and complex data sets for the purposes of investigating the relationships between one continuous dependent and 10 or more predictors and determine the factors that affect the response or target variable. At the same time, it will also be possible to evaluate the effect of each predictor with a more detailed response.

Among the skills to be developed in the study of reactive power compensation control devices in electrical power systems is the analysis of the control models of static reactive compensators. Python is free software that allows data analysis, control and simulation of electrical power systems. The objective of the article is to propose an application that allows the study of reactive power compensation that helps improve the teaching-learning process of the subject of Power Electronics. The study was based on a qualitative - descriptive methodology in which analytical - synthetic and inductive - deductive methods were used and the survey was used as empirical methods. For the processing and analysis of the information collected, the calculation of absolute and relative frequencies was used as a statistical method. The results corroborate the importance of using the proposed method to improve the teaching-learning process.

The narrative work of Cuban Calvert Casey (1924–1969) receives a decided influence from the literary and metaphysical world of the great Franz Kafka. This article shows some of the Kafkaesque constants that populate Casey’s stories. Atmospheres, symbols, characters, simulated attitudes, feelings of threat and hostility build the work of one of the most courageous and original Cuban writers of the sixties, who would also dedicate one of his essays to the author of The Metamorphosis.

Olive samples were subjected to the salting process in brine containing 1196 mol m−3 of NaCl and 402 mol m−3 of KCl. Samples were collected during 60 h and salt concentration values were determined. With the finite element method (FEM) and the minimization of the errors percentage between the simulated and experimental values, the mass transfer coefficients in the film (hm) were obtained, being 1.0072 × 10−8 and 1.2499 × 10−8 for NaCl and KCl, respectively. The salts concentration at the olive/brine interface was simulated by FEM and analyzed via SOFM. A network with 4 × 4 topology and 10000 training epochs was used. It was observed that the influence of the stationary film formed on the surface of the olives during the salting process depends on the position, the salt involved in the diffusion and that the concentration of the salts, at each point, varies according to the immersion time.

The Fourth Industrial Revolution has brought society many benefits, such as technological advances, and many challenges to be overcome. To increase the synergy between physical and digital systems, most often used in the optimization processes of physical systems, metrology 4.0 has become an essential tool for their development. A state-of-the-art paper is significant in understanding how these applications develop, focusing on Cyber-Physical Systems and Digital Twins in ionizing radiation. The online search was conducted in general and specific databases with keywords in English. Thus, twelve articles were analyzed and discussed, divided into three main themes: indirect applications, ionizing radiation metrology projects, and systematic reviews. It was possible to notice that the number of articles related to these technologies in ionizing radiation is still tiny compared to other areas, especially when compared to the industry, making it even more challenging.

ABSTRACT The geometric characteristics, physical parameters and contact parameters of coated cotton seeds were obtained through theoretical analysis and experimental measurements. A discrete element model reflecting the intrinsic parameters of cotton seeds was established, the contact parameters of coated cotton seeds were calibrated using Discrete Element Method (DEM), and the significant factors affecting the stacking angle were screened using the Plackett-Burman method. The optimal ranges of the parameters were determined by the steepest ascent method, and a second-order regression model of the stacking angle and significant parameters was established by a central composite design. The following optimal values were obtained for cotton seeds: collision recovery (0.38), static friction (0.57) and rolling friction (0.19) coefficients. The average value of the stacking angle obtained by simulations with the best combination of parameters was 30.52°, the result of the simulation test was 30.91°, and the relative error was 1.278%. It is shown that the discrete element particle model and calibration parameters of cotton seed are closer to the actual situation, which can provide theoretical reference for analyzing the precise seeding of cotton seed and optimizing the structural parameters of seed disperser.

BACKGROUND: Applying simulation for nursing education, especially in healthcare-associated infection prevention and control (HAI-PC) in developing countries has limited evidence. The study was conducted to explore educators’ perceptions of simulation as a teaching method for nursing education in HAI-PC in two Vietnamese and two Cambodian universities. METHODS: An exploratory qualitative design was applied. A focus group of 37 educators from four universities was conducted for data collection. Inductive and deductive qualitative content analysis was applied in analysing the data. RESULTS: The core category was constructed to reflect educators’ perception of scenario-based simulation (SBS) as a teaching method for nursing education in HAI prevention and control. This main category included three subcategories: (i) enhancing nursing competence; (ii) preparing students for simulation; and [1] promoting simulation pedagogy competence. CONCLUSIONS: The findings identified the importance and benefits of applying simulation as a teaching method in nursing education. Additionally, it emphasized the necessity of enhancing knowledge associated with HAIs and providing additional training on simulation for educators to improve the quality of conducting simulations.

Introduction: Rhinoplasty is indicated for performing aesthetic repairs in the nose, being functional when it also seeks to improve respiratory function. Procedure results are based on improved quality of life and patient satisfaction. It is a complex surgery that requires adequate training. In this sense, several strategies were introduced, such as educational videos, simulations, studies on cadavers and in clinical skills laboratories; however, the basis of training remains the master-apprentice relationship in surgery. Methods: The base materials used in the construction of the model were: hot glue, basin, water, detergent, epoxy putty, spatulas for crafts, nose mold, suture threads, white acetic silicone, disposable cup and spoon and coloring agents. Results: The resulting low-cost model has remarkable similarity with the external appearance and with the cartilages of the nose, allowing easy identification and handling of each structure. Allows good simulation of some steps of the open and semi-open techniques of rhinoplasty. Conclusion: The new synthetic model developed avoids ethical and legal questions that alternative methods such as animals and fresh cadavers raise. Although it requires skill for its manufacture, it has characteristics such as low cost, which favor its dissemination among medical schools. The exposed model can positively impact the learning process of rhinoplasty, revealing itself as an accessible and helpful tool for training in various stages of the technique of this complex surgery.

Different process of separation was used in the chemical industry, in particular, extraction is a process used to increase the quality of resins in oil removing impurities like organics solids and heavy metals. Supercritical carbon dioxide offers high selectivity at the end of the extraction process of light hydrocarbons from heavy oils mixture. A simulation technique in Aspen Plus ®software was used to develop the process and sensitivity analysis of the extraction configuration. The simulation of extraction process includes two output streams: the first one, a top stream (unpaved oil), and the second one a bottom stream (asphalt residue). A steady state methodology was implemented for process simulation. The sensitivity analysis was used to assess the influence of variables such as solvent flow rate, temperature and pressure. It was found a significant increase in the flow rate of unpaved oil when the solvent flow rate is increased. Optimal extraction values were selected depending on temperature and pressure effects over the process. An increase in temperature directly enhances the quality of API gravity. In certain occasions, an increase in pressure affects the light oils extraction because of product drag.

ABSTRACT Spray drift leads to wastage of spraying material and poses a threat to non-targeted crops and the environment. Therefore, the spray drift characteristics of a Ronnie Baugh (RB) tractor-trailed boom sprayer were determined through computational fluid dynamics to assist in designing the tractor for boom spraying with minimized spray drift. The wake region of the RB tractor was characterized by investigating its velocity profile, turbulent kinetic energy, and drag coefficient at different forward speeds. Additionally, spray droplet sizes and drift distances from the boom sprayer were measured at forward speeds of 4, 6, and 8 km/h, along with different wind directions. The RB tractor exhibits an estimated drag coefficient of 0.7. The results further demonstrate that, at varying forward speeds, the wake experiences low turbulent kinetic energy and minimal velocity profile variations. No spray drift was observed at tractor speeds below 4 km/h, whereas a drift of 0.19 m and 0.33 m is predicted at 6 km/h and 8 km/h, respectively. The tractor's wake is significantly influenced by changes in wind direction, resulting in varying drift distances from each nozzle due to exposure to both free and obstructed airflow. To minimize drift at higher travel speeds, it is recommended that the tractor be operated in line with the prevailing wind direction.

Introduction: The parotidectomy is an infrequent and technically complex surgery due to a difficult dissection that may affect the facial nerve, generating high degree of morbidity in patients. Animal simulation models may not reproduce the human characteristics of cervical anatomy. Therefore, it is necessary to explore other alternatives for training dissection skills. Our objective is to evaluate a parotidectomy’s techniques training program in a perfused cadaveric model. Methods: A Kern educational program was designed to train Head and Neck Surgery residents to perform total parotidectomy in a perfused cadaveric model. The evaluation was performed using Kirkpatrick model, at levels 1 (reaction), 2A (change of attitudes) and 2B (acquisition of knowledge and skills). Results: A theoretical-practical program based on lectures and high-fidelity simulation was developed. Most of the participants would recommend the course (Level 1); had greater motivation for learning (Level 2) and showed better indicators of knowledge, skills and perception of improvement in their competencies (Level 2B). Conclusion: The use of a simulated parotidectomy program in a high-fidelity model based on perfused human cadaveric models is an alternative that improves the quality of training and is useful and feasible for learning parotidectomy techniques in residents of Head and Head Surgery.

Vector-borne diseases are a cause of concern all around the world, especially in Brazil. In the past few years, the Brazilian health system faced recurrent epidemics such as Dengue and Malaria as well as new cases of Chikungunya, Zika and Yellow Fever. Vector control continues to be one of the most important counter measures against these types of diseases. Mathematical models are important tools for planning vector control strategies. In this work we present an approach in order to calculate what is the minimum vector control intensity to obtain stability in a simple population’s dynamics model of mosquitoes.We combined numerical simulations with analytic results. Transcritical bifurcations appear in our analysis considering different control’s parameters values for the eggs, larvae, pupae and adults mosquitoes populations. A discussion about combined strategies of vector control was also showed.

Collimated thermal neutron beams are obtained from neutron extraction channels in nuclear reactors for various applications in research and technology, such as neutron imaging techniques (neutron radiography, neutron radioscopy, neutron tomography, and neutron-based autoradiography). Practical setups for neutron radiography using ion beams from particle accelerators and radioisotopic sources of fast neutrons have been also developed. However, only radioisotopic sources enable autonomous and transportable thermalization systems that can produce thermal neutron collimated beams. This work presents the performance results for a prototype of a compact system that generates a collimated beam of thermal neutrons using low-activity isotopic 241Am-Be sources. It was designed with the aid of Monte Carlo simulation using the PHITS v 3.17 program. Experimental measurements of the fluence of the neutron beam produced by the built prototype showed good agreement with the simulated values by the Monte Carlo method.

ABSTRACT Introduction: Technology-enhanced simulations seem to be effective in dentistry, as they can support dental students to improve competencies in simulated environments. However, implementation of this technology in orthodontic education has not been reviewed. Objective: This scoping review aimed to comprehensively summarize the use of technology-enhanced simulations in orthodontic practice. Methods: A systematic search was conducted to identify literature on technology-enhanced simulation-based learning in orthodontic education published from 2000 to 2021. The search was conducted up to September 2021 to identify articles from Scopus, Embase, PubMed, ProQuest Dissertations & Theses Global, Google Scholar and the reference lists of identified articles. Results: The search identified 177 articles. Following the inclusion and exclusion criteria, 16 articles of 14 digital simulators were included in this review. The findings demonstrated an increasing use of technology-enhanced simulations in orthodontic education. They were designed in several formats, including three-dimensional virtual format, augmented reality, virtual reality, automaton, haptic, and scenario-based simulations. These simulations were implemented in varied areas of orthodontics including diagnosis and treatment planning, bracket positioning, orthodontic procedures, facial landmark, removable appliance and cephalometric tracing. Most included articles demonstrated the development process without outcome evaluation. Six studies provided outcome evaluations at reaction or learning levels. None of them provide the evaluation at behaviour and results levels. Conclusion: Insufficient evidence has been generated to demonstrate the effectiveness of technology-enhanced simulations in orthodontic education. However, high-fidelity computer-based simulations together with robust design research should be required to confirm educational impact in orthodontic education.

Daylighting provides significant benefits in architectural spaces, providing dynamism and enhancing the experience of the occupants in terms of wellbeing, health, and luminous and visual comfort; while leveraging energy sustainability. However, art exhibits have a difficult relationship with sunlight, as its variability makes for complications to control it, such as potential glare to occupants and artwork conservation issues due to overexposure to light. In this research I explore the luminous qualities of such spaces in Arica, Santiago and Punta Arenas to create a luminous ambience that allows for the artwork preservation without affecting the wellbeing of visitors. Through the measure of dynamic daylight metrics, findings show the best results to attain a comfortable luminous ambient were UDI 100-3000lux and ASE 1000/250hours . The daylight Glare Probability (DGP) index was used to rate human visual comfort, along with the UDI 0-200lux and ASE 1000/0hours modified metrics which allowed to rate the luminous security for artwork. From the results’ analysis, I concluded that the key factor is illuminance range max tolerance of 200 lux (IESNA, 2011), excluding direct daylight, accepting an imperceptible DGP percentage.

The principle of immersion has been a key factor in the success of many visual attractions since the 19th century, such as the cinema, reaching a new dimension with virtual reality devices for the general public. It is especially because it allows for interaction with the simulated environment, and the powerful sense of reality created by its device, that this technology is used in museum contexts. In addition to the perspectives that its use opens in terms of conservation, its ability to transport the visitor elsewhere and into another time invites us to question its geographicity: does its immersive effect come from an "organizing valence of the space"? Or is it only a simple special effect, as spectacular as it may be? This article aims to identify the modalities of "spectatorial" appropriation of this technology in a heritage context, based on an ethnographic study conducted at a virtual reality installation presented at the Museum of Art and History in Geneva (MAH). It proposes a theoretical framework for the hypothesis of an immersive and instrumented geographicity regime.

ABSTRACT Knowledge of soil water dynamics is essential for establishing appropriate methods of irrigation management. Water dynamics in unsaturated soils is a complex process that can be explained by the Richards equation. As this is a non-linear differential equation, there is no analytical solution, but requires the use of the finite element method, for example, to obtain solutions, where simulations using numerical modelling make it possible to predict the the flow of water from the soil. As such, the aim of this study was to evaluate a 2D numerical model in simulating water distribution and wet bulb formation resulting from a subsurface irrigation system, in addition to validating the generated model. The Pearson correlation coefficient (r), the coefficient of determination (R2) and the root-mean-square error (RMSE) were calculated. For each treatment, both during and after irrigation, the model showed a small relative error, high values for R2 and a positive correlation with the field data. It was concluded that the model is applicable to the design and management of subsurface irrigation systems, varying the installation depth of the drip tube, the spacing between emitters and the soil moisture, giving good results for the various simulated scenarios.

Abstract Objective: to build and validate a clinical simulation scenario on hospital nurse managerial decision-making competence for undergraduate nursing students. Method: a descriptive and methodological study was carried out in a higher education institution, with the participation of 10 judges and five players. To do so, the conceptual simulation model proposed by Jeffries and standards of the International Nursing Association for Clinical Simulation and Learning were used to prepare the scenario and the checklist. Results: the scenario was called “Managerial decision-making of nurses in the face of adverse events in a hospital”. The scenario script and checklist were built for validation. The checklist was face- and content-validated. Afterward, judges used the checklist to validate the scenario, which, in its final version, was composed of Prebriefing (seven items), Scenario in Action (18 items) and Debriefing (seven items). Conclusion: the scenario proved to be a teaching strategy that anticipates the reality of future nurses, bringing them the self-confidence to perform their activities and helping them to act critically and reflectively during decision-making processes.

The tools for process mapping, simulation, automation, analysis and reengineering have shown to be essential for the optimization and improvement of organizational management. Through process management, it is possible to improve the institutional administration, acting mainly to reduce or eliminate interferences and losses. This paper was design to apply these techniques to support process improvement. The process management program Bizagi Modeler was use to elaborate the complete and precise diagram of the process. The diagramming followed the BPMN (Business Process Modeling Notation) standard. The methodology adopted in this work is qualitative in nature. The means of data collection chosen were document analysis and verification by means of a checklist prepared according to ISO/TR 26122, of 2008. An adaptation of the SIPOC (Suppliers, Inputs, Process, Outputs and Customers) tool was adapted to informational processes, which contributed to identify key elements and to get a better understanding, indicating opportunities for improvement. Finally, an analysis was carry out presenting a proposal for improvement through process remodeling focused on the elimination of excessive bureaucratization and rework. And, a simulation of the processes (Original and Improved) was performed, using the Bizagi Studio program, to demonstrate and confirm that the scenario with the implemented improvement proposal offered a better result in its execution and processing.

ABSTRACT This study was carried out for two purposes: comparing performances of Regression Tree and Automatic Linear Modeling and determining optimum sample size for these methods under different experimental conditions. A comprehensive Monte Carlo Simulation Study was designed for these purposes. Results of simulation study showed that percentage of explained variation estimates of both Regression Tree and Automatic Linear Modeling was influenced by sample size, number of variables, and structure of variance-covariance matrix. Automatic Linear Modeling had higher performance than Regression Tree under all experimental conditions. It was concluded that the Regression Tree required much larger samples to make stable estimates when comparing to Automatic Linear Modeling.

ABSTRACT This study aimed to introduce R package pedSimulate, which was built to simulate pedigree, genetic merit, phenotype, and genotype data. These are amongst the most important data types that animal breeders and quantitative geneticists deal with. Twenty pedigrees with ten generations were simulated applying different combinations of three parameters: genetic variance (10 vs. 20), proportion of males selected (10 vs. 20%), and the pattern for selecting females (random, positively, or negatively based on own phenotype or parent average). Males were selected positively based on parent average. Consequently, assortative mating was applied to the pedigrees in which females were positively selected based on their own phenotype or parent average. Disassortative mating was applied to the pedigrees in which females were selected negatively based on phenotype or parent averages. Genetic gain and response to selection over generations were positive for all the pedigrees due to high selection intensity on males, mating each male with multiple females, and moderate to high heritability (0.25 and 0.40 for genetic variances 10 and 20, and the residual variance of 30). Genetic variance showed a slightly increasing trend over generations by assortative mating and lower selection intensity on males. Selection intensity on females was the same in all the pedigrees. This study provided examples of how R package pedSimulate can be adopted for pedigree, genetic merit, phenotype, and genotype data simulation in animal breeding studies. By using different functions and combining different parameters for their arguments, many scenarios can be simulated by R package pedSimulate.

Climate change and rising temperatures are some of the biggest challenges tropical cities face. These cities need to be designed to accommodate high population growth while providing a comfortable thermal environment. In this context, we propose a framework for developing urban design guidelines with a focus on improving thermal comfort in outdoor environments, a concept known as Outdoor Thermal Comfort (OTC). The framework is based on computing climate variables such as temperature, wind speed, humidity, and others for several urban design strategies at the district scale. Furthermore, we use the spatial occupancy over the course of the day in the district to calculate an overall OTC performance score. Finally, the design strategies are ranked and represented in a three-dimensional space. The strategies are extracted from the body of knowledge of urban planning and design, and adjusted to local status and building codes. The climate variables are computed using numerical climate models, and the OTC performance score is calculated using a statistical risk management model. The guidelines discussed in this paper are limited to passive design strategies such as urban geometry, orientation and vegetation for tropical cities with high density. These guidelines can be used to support architects and urban planners in the early design stages of a new district.

This article is part of the Com2SiCa research, which seeks two objectives: firstly, to understand the diversity of human behavior and the way in which it can evolve during a major, sudden and unpredictable disaster; and, secondly, to analyze the trajectories associated with spontaneous decisions to evacuate (or not) the area where a disaster has occurred.Knowledge in this field is scarce because of the difficulty, for both practical and ethical reasons, to address the diversity of behavioral responses during the course of a disaster. In order to capture this precise moment, “during” the event, we have developed an experimental field survey methodology that relies on an immersive visual and acoustic simulation. By immersing participants in disaster scenarios, this innovative method aims to produce data on observable behavioral responses to emergency situations. Trialed in two coastal cities, Nice and Le Havre, in order to test the replicability of the approach and compare the results, it was designed for "natural" or "industrial" disaster scenarios with common temporal characteristics, that is, a sudden, rapid onset with little or no warning. We present the approach, its goals and the type of methodological innovation it entailed. The city of Le Havre was chosen as a case-study to test our method. Our results highlight the validity and value of conducting immersive field investigations and confirm the fact that, for the same disaster scenario, people can behave in a wide variety of ways, and may be alert, in control or in a state of panic. Some people are static (for example, immobile or stunned), while others are dynamic (for example, searching for loved ones or fleeing). The result of this behavioural diversity is a heterogeneity in the trajectories taken to evacuate the site of the disaster or to take cover. We also observe that trajectories depend on the spatial configuration of the location where the event takes place. Knowledge of this behavioural heterogeneity as well as the influence of location could be useful to decision-makers and other stakeholders.

ABSTRACT The uniformity and quality of spraying depend on the stability of the spray boom, defined as the suspension system between the boom and the machine chassis. This paper presents a procedure for improving the performance of passive spray bar suspensions through parameter adjustment. Two multibody dynamics models of a tractor sprayer set were developed to evaluate their suspension systems: a rigid body dynamics model (RBDM) and a finite element model (FEM) using deformable bodies. To calibrate the models in the experiment, an accelerating force was applied to the suspension, and the displacements of the shock absorber and the rubber springs were monitored. The FEM is more suitable for the evaluation of the horizontal oscillations of the bar, based on root mean square (RMS) values and a standard curve used to evaluate the stability of the bar. The horizontal stiffness of the bar significantly influences the oscillatory displacement and must be included in the simulation models. Resizing the structure can reduce the horizontal oscillations of the bar.

We live today in a new virtual and global space. Computers and electronic devices (smartphones) make us stay online, immersed in the cyberspace, in a network connected in an all-to-all system. An increasingly hyperreal world implies how our perception depends on simulations. The whole system is swamped by indeterminacy and reality is absorbed by the hyperreality of the simulation, says Baudrillard. Hyperreality and simulation replace and seem more real than reality itself. We must reflect on what the virtual is and what are its effects or consequences, since each new electronic medium or digital device brings new procedures, behaviors, and ways of being. Following a theoretical and conceptual approach, the aims of this study are: a) to understand the implications of the virtual and its effects, and b) to problematize the ordinary experiences of hyperreality that reshape and restructure patterns of culture and social interaction. The virtual is not just what Baudrillard defines as illusion. The virtual thinks for us. In the recent past, it was the opposite. We conclude that technology has accustomed us to virtual mediatization and now we perceive it as real without distinction, preferring the unlimited power of the illusory with its effects to the limitations of the real.
