- Abstract
This report consists of several papers written, but not published, during the course of the WARNET study of requirements for a network of relatively low-cost, interconnected combat simulators for use in training pilots for combat readiness. It is projected that such a network would allow a number of aircraft to fight each other in simulated but realistic battles and incorporate many combat factors critical to the survival of the pilots. It would also allow aircraft to interact with ground vehicles and surface-to-air missiles. It is argued that this training would enable pilots to transfer skills from training to actual combat environments without the high risk of failure due to lack of experience. This conceptual research effort used information obtained from fighter pilots and computer and training experts to examine a range of questions and options that might be considered with a network of tactical aircraft combat simulators. Although the main emphasis of the research was on training, some consideration was given to the use of such a network in aircraft development and in pilot selection. While such a network of aircraft simulators remains to be built, the results of this study suggest that such a network should be given serious consideration. (DB)

Senkbeil, Karsten, Martin, Gillian, and O'Rourke, Breffni
- Abstract
This paper discusses the potential of immersing foreign language learners in Social Virtual Reality (SVR) in an international seminar, designed by the authors, called SpEakWise VR, combining the tandem language learning paradigm with gamification in immersive virtual environments. SpEakWise VR builds on an existing telecollaboration (SpEakWise) between undergraduate students in Trinity College Dublin and Hildesheim University. We set out to explore how inclusion of an SVR activity influences student engagement, learning involving intercultural and multilingual problem solving, and team building. This paper presents initial observations from our research, concerning multimodality in embodied immersion and code-switching, and proposes future avenues of inquiry.

Kaplan-Rakowski, Regina and Gruber, Alice
- Abstract
Many language learners lack the motivation to read complex texts. Because high-immersion Virtual Reality (VR) is increasingly reported to be highly motivating, the goal of our study was to compare English as a Second Language (ESL) learners' (N=79) motivation while reading a story with subtitles in VR (experimental group) versus reading the same story screencast in two-dimensions (2D -- control group). The Wilcoxon signed-rank test revealed that learners' motivation in VR was significantly higher compared with the control group. Our finding confirmed that VR is highly motivational in the context of reading foreign texts and can be useful for Computer Assisted Language Learning (CALL) researchers, practitioners, and instructional designers. This analysis is a part of a larger study (Kaplan-Rakowski & Gruber, 2023) on VR facilitating reading tasks.

107. Comparing Lexical Complexity Using Two Different VE Modes: A Pilot Study
- Author

Shiroyama, Tomotaka
- Abstract
The aim of this study is to compare how two different Virtual Exchanges (VE) contribute to language learning in a Japanese university context. Task-Based Language Teaching (TBLT) using VE has been a focus in this study. There are huge advantages of using technology in language teaching such as increasing language use opportunities, feedback, and others (Lee, 2016). However, many recent TBLT and VE studies have focused on students' interaction in the classroom (Hagley, 2020). This study investigated whether two different types of VEs have the potential to promote 'real-world communication' in a university context. The findings show that there was no significant difference regarding lexical complexity between both modes. The result suggests that both modes are unlikely to enhance students' vocabularies.

- Abstract
This paper describes a project which aims to create an authoring environment for simulation-based training in order to illustrate features necessary for: (1) an environment which can be used by teachers/trainers with minimum technical skills; (2) rapid prototyping by all courseware producers; (3) and tools for model building. The paper begins with a section summarizing results of an earlier survey of commercial and educational producers of computer-based training materials. The second section outlines training, authoring, delivery, and development requirements for simulation courseware, and the third section lists overall project requirements. The fourth section describes the current phase of the project, i.e., the production of a demonstration toolkit. Requirements for prototype courseware are summarized in the fifth section, including general requirements, courseware functionality, and assumptions. The sixth section presents prototype model requirements, covering general requirements, typical model components, and the nature of required models. The seventh section lists demonstration phase toolkit requirements, including general requirements, modelling tools, and authoring and learner interface tools. General, modelling, and authoring requirements not addressed by the demonstrator phase are discussed in the eighth section. The appendix includes a description of two courseware products to be produced in the demonstration phase and a list of the abstract properties of model objects. (MES)

- Abstract
In this paper, we describe the design for PurpleState, an internship simulation that applies the epistemic game model for informed civic learning. PurpleState places students in the role of interns at a political media firm and asks them to design a media campaign on a state level policy issue. Unlike the use of these models in STEM education, here we use the internship simulation to develop key skills, knowledge, and values "and" to ask participants to reflect on the simulation itself. In this way, we utilize PurpleState to help participants develop the argumentative thinking, epistemic cognition, and self-efficacy for informed citizenship and the reflective capacity to apply their understanding of the political ecosystem being simulated. The design of PurpleState contributes to the use of simulations in civic education by focusing on state level issues and using communities of practice as a model for learning and transfer to local civic engagement.

- Abstract
It is not immediately clear how costly behavior that benefits others evolves by natural selection. By saving on inherent costs, individuals that do not contribute socially have a selective advantage over altruists if both types receive equal benefits. Restrained consumption of a common resource is a form of altruism. The cost of this kind of prudent behavior is that restrained individuals give up resources to less-restrained individuals. The benefit of restraint is that better resource management may prolong the persistence of the group. One way to dodge the problem of defection is for altruists to interact disproportionately with other altruists. With limited dispersal, restrained individuals persist because of interaction with like types, whereas it is the unrestrained individuals that must face the negative long-term consequences of their rapacity. Here, we study the evolution of restraint in a community of three competitors exhibiting a nontransitive (rock-paper-scissors) relationship. The nontransitivity ensures a form of negative feedback, whereby improvement in growth of one competitor has the counterintuitive consequence of lowering the density of that improved player. This negative feedback generates detrimental long-term consequences for unrestrained growth. Using both computer simulations and evolution experiments with a nontransitive community of Escherichia coli, we find that restrained growth can evolve under conditions of limited dispersal in which negative feedback is present. This research, thus, highlights a set of ecological conditions sufficient for the evolution of one form of altruism.

113. Immersive Virtual Reality versus Webcam in an Online Language Course

Herrera, Borja
- Abstract
This paper investigates the differences between Immersive Virtual Reality (IVR) and the webcam (WBC) in the context of a Spanish distance-learning course. Two specific objectives were set: (1) to determine the existence of a relationship of dependence between the device used and the oral interaction, and (2) to analyse the existence of a dependency relationship between the device utilised and the perception of copresence. To that end, online courses and semi-structured interviews were conducted. Regarding the first objective, there is a higher chance of speaking exchanges between student-tutor and tutor-student when using WBC. As for the second objective, we did not have sufficient feedback to determine whether the perception of copresence varies depending on the two profiles. However, the analysis indicates that non-verbal communication was essential for IVR volunteers to experience copresence. The conclusions suggest that the IVR could be more appropriate than WBC for socio-constructivist and communicative teaching pedagogies [For the complete volume, "CALL and Professionalisation: Short Papers from EUROCALL 2021 (29th, Online, August 26-27, 2021)," see ED616972.]

- Abstract
This paper delves into the underlying phases involved in designing, developing, and deploying Augmented Reality (AR) applications and game-based scenarios that will be implemented during intercultural exchanges among students in two different academic institutions in Sweden and Cyprus. Building on principles of design-based research (Barab & Squire, 2004; Klopfer & Squire, 2008), the aim is to expand the learning ecology by leveraging instructional tools and developing novel scenarios to broaden the trajectories of collaboration, intercultural understanding and communication, and cultural knowledge. The AR applications and scenarios are in the process of being developed as part of the Digital Methods Platform for Arts and Humanities (DiMPAH) project, where game-based activities will foster intercultural collaboration, exploration of cultural heritage sites, intercultural understanding, knowledge, and interaction. Adopting a bottom-up approach, instructors collaborate with a software developer and an extended research team to design pedagogically and culturally potent scenarios embedded in novel technologies that bring the virtual into the physical world.

- Abstract
This study employs simulated electronic paper to investigate critical issues and focuses on improving legibility of display and reducing users' visual fatigue. Three critical factors--choice of surface treatment, ambient illumination, and bending curvature--are evaluated through the method of a letter-search task. The results show that subjects performed better on legibility and felt less visual fatigue with an anti-glare treatment. Choosing the better anti-glare treatment instead of the anti-reflection series can save significant cost for manufacturers. In addition, ambient lighting of 1500 lux is more appropriate for reading on electronic paper than an environment with extreme illumination (e.g., 8000 lux). The present study also found that curvature had no impact on legibility or visual fatigue. These evaluations of simulated electronic paper may provide manufacturers useful information in fulfilling ergonomic requirements for product design.

- Abstract
Genomes are tremendous co-evolutionary holistic systems for molecular storage, processing and fabrication of information. Their system-biological complexity remains, however, still largely mysterious, despite immense sequencing achievements and huge advances in the understanding of the general sequential, three-dimensional and regulatory organization. Here, we present the GLOBE 3D Genome Platform a completely novel grid based virtual "paper" tool and in fact the first system-biological genome browser integrating the holistic complexity of genomes in a single easy comprehensible platform: Based on a detailed study of biophysical and IT requirements, every architectural level from sequence to morphology of one or several genomes can be approached in a real and in a symbolic representation simultaneously and navigated by continuous scale-free zooming within a unique three-dimensional OpenGL and grid driven environment. In principle an unlimited number of multi-dimensional data sets can be visualized, customized in terms of arrangement, shape, colour, and texture etc. as well as accessed and annotated individually or in groups using internal or external data bases/facilities. Any information can be searched and correlated by importing or calculating simple relations in real-time using grid resources. A general correlation and application platform for more complex correlative analysis and a front-end for system-biological simulations both using again the huge capabilities of grid infrastructures is currently under development. Hence, the GLOBE 3D Genome Platform is an example of a grid based approach towards a virtual desktop for genomic work combining the three fundamental distributed resources: i) visual data representation, ii) data access and management, and iii) data analysis and creation. Thus, the GLOBE 3D Genome Platform is the novel system-biology oriented information system urgently needed to access, present, annotate, and to simulate the holistic genome complexity in a unique gateway towards a real understanding, educative presentation and curative manipulation planning of this tremendous evolutionary information grail - genomes.

- Abstract
A simulation is described in terms of its three major aspects: the scenario, the underlying model, and the instructional overlay. The major focus of this paper is the instructional overlay as the component that serves to optimize learning and motivation. Functions of simulations are identified as the acquisition of content, the application of the content, and the assessment of learning. Five simulation features that act as vehicles for achieving these functions are then discussed: generality, example, practice, feedback, and help. A general model for the design of computer-based simulations is presented which offers prescriptions for the design of the introduction, acquisition, application, and assessment stages of simulations and for dealing with the issue of control (system or learner). Variations on the general model are then presented which are based on the nature of the behavior (procedures, process principles and causal principles), complexity of the content, form of learner participation, form of changes (physical or non-physical) and motivational requirements. In conclusion, it is noted that these prescriptions are only a first step in an attempt to construct a validated prescriptive theory for the design of computer simulations, and that considerable research and extensive field tests are needed to provide the information necessary for both confirmation and revision of the various aspects of the theory.

- Abstract
This paper describes the development and current state of videodisk technology in Canada. The first section focuses on the technology itself, i.e., the disks, disk players, and the possibilities they offer for interaction between learner and machine. The current costs of the technology and the probable effect of these costs on the market are also discussed. The second section reports on a survey of the research and production of videodisks in Canada, and includes a discussion of the contents, educational design, costs, and features of projects completed by ACCESS Alberta, the Univesity of Alberta in Edmonton, Simon Fraser University in British Columbia, and the Ontario Institute for Studies in Education, among others. Issues involved in most of the projects include: (1) the effective design of interactive learning programs; (2) coordination of the team producing the videodisk; and (3) cost of the technology both to produce and to use. It is concluded that, although the potential of the educational videodisk is widely recognized in Canada, its wide acceptance as a valid, affordable alternative for educational delivery is still open to question. A list of contact individuals and references is included. (DB)

- Abstract
These proceedings contain the papers of the 11th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2014), October 25-27, 2014, which has been organized by the International Association for Development of the Information Society (IADIS) and endorsed by the Japanese Society for Information and Systems in Education (JSISE). The CELDA 2014 conference aims to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a fast pace and affecting academia and professional practice in many ways. Paradigms such as just-in-time learning, constructivism, student-centered learning and collaborative approaches have emerged and are being supported by technological advancements such as simulations, virtual reality and multi-agents systems. These developments have created both opportunities and areas of serious concerns. This conference aimed to cover both technological as well as pedagogical issues related to these developments. The conference included the Keynote Lecture: "Designing Learning Environments in a Digital Age: The Quest for What to Consider," by Professor Jan Elen, Faculty of Psychology and Educational Sciences, K.U. Leuven, Belgium.

- Abstract
We studied the influence of the operational variables (viz. ethylene-glycol concentrations of 50-70%, temperatures of 155-185 degrees C, times of 30-90 min and numbers of PFI beating revolutions of 500-1500) on pulp yield and various paper properties (breaking length, stretch, burst index, tear index and brightness) obtained in the ethylene-glycol pulping of vine shoots, cotton stalks, leucaena (Leucaena leucocephala) and tagasaste (Chamaecytisus proliferus). The fuzzy neural network models used reproduced the experimental results with errors less than 15% and smaller than those provided by second-order polynomial models in all cases. An ethylene-glycol concentration of 65% at 180 degrees C for 75 min and 1500 PFI beating revolutions were found to provide substantial savings in energy, chemicals and facility investments as a result of operating under milder conditions than the strongest ones studied in this work. Tagasaste was found to be the most suitable raw material among those tested as it provided the paper sheets with the highest breaking length (4644 m), stretch (2.87%), burst index (2.46 kN/g), tear index (0.33 m Nm(2)/g) and brightness (40.92%); its pulp yield was also high (62.88%), which reflects efficient use of this raw material.

- Abstract
Hemispatial neglect is a common disorder that can occur after a lesion in the right hemisphere. Its main characterization is the difficulty in processing visual stimuli emanating from the space contralateral to the lesion. Pencil and paper tests (such as target cancellation, line bisection, or drawing copy) are used to diagnose neglect. We propose using virtual reality technology and haptic force feedback to enhance pencil and paper tests. Our system can track the patients' eye-gaze and their hand movements. Also, the efficiency of several techniques used to decrease the neglect in different sensory spaces are investigated.

127. An Empirical Study on Immersive Technology in Synchronous Hybrid Learning in Design Education

- Abstract
Immersive technology plays an increasingly important role in design education, supporting digital literacy and experiential learning in higher education, particularly in the post-COVID-19 context. Many design disciplines, such as Architecture and Landscape Design, which used to rely heavily on physical field trips, and dialogic studios as signature pedagogies, had to adapt to the proliferation of innovative educational technologies due to the suspension of face-to-face teaching and learning. Augmented reality and virtual reality are now extensively used in technology and design education to support a more interactive, collaborative, and student-centred approach to learning. This paper expands on a pilot research study on the transition from traditional signature pedagogies of studio-based design education to technology-enhanced collaborative learning to support experiential learning. Based on Kolb's experiential learning framework concerning four learning modes, namely, concrete experience (CE), reflective observation (RO), abstract conceptualisation (AC), and active experimentation (AE), this paper analyses data from 75 undergraduate students across four cohorts in three different higher education institutions in Hong Kong. They were surveyed on their experiences of synchronous hybrid virtual experiential learning with design and technology curricula. Furthermore, six students were interviewed about their experiences. The research findings confirm two research hypotheses showing that immersive experiential learning could constructively align RO and AE, thus bringing an overall positive impact on the experiential learning process, but shows no conclusive influence on promoting CE, especially AC. The quantitative findings and qualitative results gave new insights into the discussion of the theoretical and practical implications of the study.

- Abstract
Laboratory experiments and numerical simulations have shown that the outcome of cyclic competition is significantly affected by the spatial distribution of the competitors. Short-range interaction and limited dispersion allows for coexistence of competing species that cannot coexist in a well-mixed environment. In order to elucidate the mechanisms that destroy species diversity we study the intermediate situation of imperfect mixing, typical in aquatic media, in a model of cyclic competition between toxin producing, sensitive and resistant phenotypes. It is found, that chaotic mixing, by changing the character of the spatial distribution, induces coherent oscillations in the populations. The magnitude of the oscillations increases with the strength of mixing, leading to the extinction of some species beyond a critical mixing rate. When mixing is non-uniform in space, coexistence can be sustained at much stronger mixing by the formation of partially isolated regions, that prevent global extinction. The heterogeneity of mixing may enable toxin producing and sensitive strains to coexist for very long time at strong mixing.

Numerical simulation of polypropylene laminated paper insulation is a serious challenge, as it must take into account the layered structure and presence of longitudinal and radial gaps in the coils of the winded tape for cables with sector-shape conductive cores. Thus far, it has been performed only with serious simplifications. We propose a technique for numerical modeling of electric parameters in this type of insulation by reducing a complex 3D problem to a simplified 2D model that takes into account the main influencing factors. The results of modeling the distribution of electric field strength and current density in insulation are presented, and the influence of the location of gaps between the edges of winded tape on the conductivity of cable insulation is estimated. Analytical expressions are obtained for estimating the electrical resistance of insulation while taking into account the parameters of the butt gap between the insulating tapes. The results of calculations, numerical modeling, and experimentally measured values of electrical resistance are compared, showing that there is a good match. The main effects affecting the properties of polypropylene laminated paper insulation are described. [ABSTRACT FROM AUTHOR]

- Abstract
In this paper, we describe a teaching scenario using a virtual environment (known also in the context of the 'metaverse'). This is motivated by the challenges that arise during the pandemic. More and more teaching scenarios are transferred to online learning settings, which allow learning at any time and at any time. One of the possibilities are virtual 3D environment. These allow more intensive immersion than for example video conferences. Furthermore, they offer new didactic concepts, for example, for group activities. The benefit of using virtual 3D environments we demonstrate by a concrete learning scenario: the simulation of robot programming. A further advantage when using virtual 3D environments are personal assistants (conversational/ pedagogical agents), for example, to the ease the work load borne by teachers; meanwhile, this works well also with natural language due to advantage stage of artificial intelligence implementations.

- Abstract
Researchers and educators have been exploring innovative methods in entrepreneurship education to address traditional approach failure at engaging students and developing their skills. Educational technology has shown promising results in early studies. Yet, there is a scarcity of reviews on their effectiveness in developing entrepreneurial competencies. This paper systematically reviews the empirical literature on the outcomes of educational technology used to teach entrepreneurship at higher education institutions. From an initial 316 search hits, 26 articles were selected for in-depth review. The learning outcomes were translated into entrepreneurial competencies, using the EntreComp Framework as a reference. Findings show that educational technologies, in general, positively impacted entrepreneurial competencies, especially financial and economic literacy, motivation and perseverance, and initiative taking. Gaming and simulations were the most researched, having an overall positive influence, while online learning and MOOCs showed limited and sometimes contradictory effects. The study fills the scholarly gap by connecting educational technology, entrepreneurship education, and entrepreneurial competencies. It provides a basic mapping linking each educational technology to the competencies it develops and advocates for a competency-based pedagogy in the delivery and assessment of entrepreneurship education. Educators can apply the findings and the mapping developed in this study to design and deliver entrepreneurship courses, incorporating educational technologies more insightfully and effectively in their pedagogies.

- Abstract
This study investigates how learners collaboratively construct embodied geometry knowledge in shared VR environments. Three groups of in-service teachers collaboratively explored six geometric conjectures with various virtual objects (geometric shapes) under the guidance of a facilitator. Although all the teachers were in different physical locations, they logged into a single virtual classroom with their respective groups and were able to see and manipulate the same geometric shapes as well as see their collaborators' avatars and actions on the shapes in real time in the shared virtual space. This paper introduces a novel multimodal data analysis method for analyzing participants' interactive patterns in collaborative forms of actions, gestures, movements, and speech. Results show that collaborative speech has a strong simultaneous relationship with actions on virtual objects and virtual hand gestures. They also showed that body movements and positions, which often focus on virtual objects and shifts in these movements away from or around the object, often signal key interactional collaborative events. In addition, this paper presents five emergent multimodality interaction themes showing participants' collaborative patterns in different problem-solving stages and their different strategies in collaborative problem-solving. The results show that virtual objects can be effective media for collaborative knowledge building in shared VR environments, and that structured activity design and moderate realism may benefit shared VR learning environments in terms of equity, adaptability, and cost-effectiveness. We show how multimodal data analysis can be multi-dimensional, visualized, and conducted at both micro and macro levels.

- Abstract
3D holograms are an effective tool for visualization, and their utilization in chemistry teaching can be beneficial in improving learning outcomes. However, studies on students' opinions about holograms in chemistry teaching and learning are scarce. The research aimed to examine the views of chemistry students on the application of 3D holograms in organic chemistry learning at the university level. In this cross-sectional study, 55 first-year chemistry students at the University of Novi Sad (Serbia) participated. The sample consisted of students aged 18-20, of which 85.5% were female and 14.5% were male. An online questionnaire designed for this research was used to collect quantitative data. Data obtained after an eight-week application of 3D holograms in organic chemistry classes revealed that students have a positive opinion about the application of 3D holograms in organic chemistry classes. Therefore, the research results imply that teachers should apply 3D holograms in chemistry classes.

Piety, Philip J.
- Abstract
The paper discusses the use of "Productive Disciplinary Engagement" (PDE) for a curricular project that features a technology-based alternate reality game (ARG) with the objective of teaching undergraduate students about the collaborative nature of STEM careers. Much of the PDE research uses PDE as either a design-principle or as an analytics lens. This project does both. Most of this extant research focuses on spoken discourse to teach disciplinary knowledge. This project uses workplace documentary texts that are embedded within a semester-long undergraduate course designed to teach students collaboration skills using the context of natural disasters. A range of texts are used in this design from didactic to disciplinary. Students learn about professional work through educational renditions of professional cultural historical activity systems. This paper focuses on design decisions and illustrates some ways that workplace documents can be used in education.

- Abstract
As part of the usual end of year meeting that has been a feature of the National Center for Engineering and Technology Education (NCETE) project, a conference intending to provide a forum for young voices in an outside of the Center was organized. The basic model for the gathering was borrowed from track and field. This was to be an intellectual conference meet, to which teams of scholars and their coaches/mentors would come, drawn from university programs where scholars worked at the intersection of engineering education and technology education, to share ideas and to engage each other. The conference theme was to be Research in Engineering and Technology Education (RETE). These proceedings summarize ideas from the presentations made during the day. One group of papers focused upon exploring "teachers' knowledge and dispositions to" science, technology, engineering, and mathematics (STEM) curriculum and instruction. A second set of papers focused upon "dealing with ill-defined problems and complex systems." A third set of papers "examine problem solving predisposition in children and adolescents." Three of the papers explore student interest in STEM careers. Beyond papers that cluster thematically are a few that pursue interesting lines that were influenced by cognitive and creativity considerations.

- Abstract
Sensor devices, such as accelerometers, are widely used for measuring physical activity (PA). These devices provide outputs at fine granularity (e.g., 10-100 Hz or minute-level), which while providing rich data on activity patterns, also pose computational challenges with multilevel densely sampled data, resulting in PA records that are measured continuously across multiple days and visits. On the other hand, a scalar health outcome (e.g., BMI) is usually observed only at the individual or visit level. This leads to a discrepancy in numbers of nested levels between the predictors (PA) and outcomes, raising analytic challenges. To address this issue, we proposed a multilevel longitudinal functional principal component analysis (mLFPCA) model to directly model multilevel functional PA inputs in a longitudinal study, and then implemented a longitudinal functional principal component regression (FPCR) to explore the association between PA and obesity-related health outcomes. Additionally, we conducted a comprehensive simulation study to examine the impact of imbalanced multilevel data on both mLFPCA and FPCR performance and offer guidelines for selecting optimal methods., (© 2024 The Author(s).

- Abstract
Background: High-efficient pesticide application equipment for protected cultivation is scarce. In response, a fixed-pipe twin-fluid clod fogger (FTCF) was proposed as a potential solution. To investigate the optimal nozzle layout and spray performance, a computational fluid dynamics (CFD) model was used to study the airflow distribution and spray deposition of a FTCF with different nozzle settings using the Euler-Lagrange approach. Specifically, two piping configurations, middle-cross-inverted (MCI) and bilateral-malposed-opposite (BMO), were combined with three nozzle spacings (2 m, 3 m, 4 m) resulting in six nozzle settings. Additionally, a greenhouse spray trial was conducted to test the performance of FTCF with the selected nozzle settings and to validate the model., Results: The simulation results revealed that MCI piping configuration exhibited a stronger airflow disturbance compared to BMO configuration, indicating a more significant air-guided effect in the MCI configuration. Combining this finding with the ground droplet distribution analysis of MCI piping configuration, it was observed that MCI-2 m had the lowest coefficient of variation (CV) for ground deposition (20.56%). Consequently, MCI-2 m was determined as the most optimal nozzle setting. Verification results demonstrated a high consistency between experimental and simulated spray deposition results., Conclusions: The FTCF system effectively generated a three-dimensional airflow field throughout the greenhouse environment. Furthermore, jet flow produced by FTCF disrupted the overall airflow pattern within the greenhouse space which facilitated droplet suspension and dispersion. This study provides valuable insights and innovative ideas for enhancing pesticide application technologies in protected cultivations. © 2024 Society of Chemical Industry., (© 2024 Society of Chemical Industry.)

There is extensive evidence that network structure (e.g., air transport, rivers, or roads) may significantly enhance the spread of epidemics into the surrounding geographical area. A new compartmental modeling framework is proposed which couples well-mixed (ODE in time) population centers at the vertices, 1D travel routes on the graph's edges, and a 2D continuum containing the rest of the population to simulate how an infection spreads through a population. The edge equations are coupled to the vertex ODEs through junction conditions, while the domain equations are coupled to the edges through boundary conditions. A numerical method based on spatial finite differences for the edges and finite elements in the 2D domain is described to approximate the model, and numerical verification of the method is provided. The model is illustrated on two simple and one complex example geometries, and a parameter study example is performed. The observed solutions exhibit exponential decay after a certain time has passed, and the cumulative infected population over the vertices, edges, and domain tends to a constant in time but varying in space, i.e., a steady state solution., (© 2024.

- Abstract
This study investigates the forces exerted on organs during swallowing, specifically focusing on identifying forces other than those resulting from direct organ contact. Using a swallowing simulator based on the moving particle method, we simulated the swallowing process of healthy individuals upon the ingestion of thickened foods, which were simulated as shear-thinning flow without yield stress. We extracted the resultant force vectors acting on the organs and shape of the bolus at each time interval. The simulation results confirmed that the bolus originates from tongue movement and is transferred between the oral cavity and pharynx, with each organ's coordinated movements with the tongue occurring at their respective positions, as indicated by the balance of the resultant force vectors. Utilizing the information about the resultant force vectors obtained through simulations, we calculated the physical parameters of impulse, energy, and power. The variations in these physical parameters were aligned with the behaviors of both the biological system and the food bolus during swallowing. The force values calculated from the simulations closely approximate the theoretical values. Furthermore, the forces calculated from the simulations were relatively smaller than the force values derived from pressure information, such as that from high-resolution manometry and tongue pressure sensors. This difference can be attributed to the simulations extracting only the forces exerted on the organ by the food bolus. Force information on organs has the potential to provide a new interpretation of conventional mechanical indicators such as manometry and tongue pressure sensors., (© 2024 The Author(s).

- Abstract
Soft biological tissues, such as arterial tissue, have the ability to grow and remodel in response to damage. Computational method plays a critical role in understanding the underlying mechanisms of tissue damage and healing. However, the existing healing model often requires huge computation time and it is inconvenient to implement finite element simulation. In this paper, we propose a computationally efficient gradient-enhanced healing model that combines the advantages of the gradient-enhanced damage model, the homeostatic-driven turnover remodeling model, and the damage-induced growth model. In the proposed model, the evolution of healing-related parameters can be solved explicitly. Additionally, an adaptive time increment method is used to further reduce computation time. The proposed model can be easily implemented in Abaqus, requiring only a user subroutine UMAT. The effectiveness of proposed model is verified through a semi-analytical example, and the influence of the variables in the proposed model is investigated using uniaxial tension and open-hole plate tests. Finally, the long-term development of aneurysms is simulated to demonstrate the potential applications of the proposed model in real biomechanical problems., (© 2024.

- Abstract
The fifth modeling workshop (5MW) was held in June 2023 at Favrholm, Denmark and sponsored by Recovery of Biological Products Conference Series. The goal of the workshop was to assemble modeling practitioners to review and discuss the current state, progress since the last fourth mini modeling workshop (4MMW), gaps and opportunities for development, deployment and maintenance of models in bioprocess applications. Areas of focus were four categories: biophysics and molecular modeling, mechanistic modeling, computational fluid dynamics (CFD) and plant modeling. Highlights of the workshop included significant advancements in biophysical/molecular modeling to novel protein constructs, mechanistic models for filtration and initial forays into modeling of multiphase systems using CFD for a bioreactor and mapped strategically to cell line selection/facility fit. A significant impediment to more fully quantitative and calibrated models for biophysics is the lack of large, anonymized datasets. A potential solution would be the use of specific descriptors in a database that would allow for detailed analyzes without sharing proprietary information. Another gap identified was the lack of a consistent framework for use of models that are included or support a regulatory filing beyond the high-level guidance in ICH Q8-Q11. One perspective is that modeling can be viewed as a component or precursor of machine learning (ML) and artificial intelligence (AI). Another outcome was alignment on a key definition for "mechanistic modeling." Feedback from participants was that there was progression in all of the fields of modeling within scope of the conference. Some areas (e.g., biophysics and molecular modeling) have opportunities for significant research investment to realize full impact. However, the need for ongoing research and development for all model types does not preclude the application to support process development, manufacturing and use in regulatory filings. Analogous to ML and AI, given the current state of the four modeling types, a prospective investment in educating inter-disciplinary subject matter experts (e.g., data science, chromatography) is essential to advancing the modeling community., (© 2024 Wiley Periodicals LLC.)

- Abstract
With an urgent change of the learning approach from face-to-face to online learning in academic institutions due to the COVID 19, this medium's effectiveness is arguable, particularly in the case of practicalbased courses. This paper discusses our experience in handling photography course during this pandemic time using an online simulator and proposes an interactive VR-based camera simulator to learn photography course using online platform. Photography has been selected as the main course based on the actual learning experience at the Applied Media Department, Higher Colleges of Technology (HCT), Men's Campus Abu Dhabi, UAE. We explore 10 online digital camera simulators and present an analysis of these applications' features, usability, and interactivity. Then, one chosen simulator is implemented to teach a 15 weeks photography course through a digital platform, and the feedbacks from students were collected and discussed. It is found that using a DSLR simulator allows students to explore and understand the concept of using a camera and photography. This paper presents the proof of concept for a DSLR simulator based on immersive environment and virtual reality, which is enhanced with interactive features that mimic the actual DSLR camera. Our proposal includes suggestions of missing features for the current simulators to overcome the course's physical and practical issues. [For the full proceedings, see ED623569.]

- Abstract
This paper describes how an Immersive Virtual Reality (VR) Classroom in a secondary school in Singapore is used to enhance learning through visualization and deepen understanding of science and increase interest and enjoyment in science. The VR Classroom is a futuristic classroom that taps the affordances of VR and AR to enhance HCI (Human-Computer Interactions) through visualization and interactivity, as well as increase engagement and enjoyment in the school curriculum. About the size of a regular classroom, this VR Classroom has three units of Oculus Rifts coupled adorned with life-size wall Augmented Reality posters of the Coronavirus and cells. Drawing from the author's experience in implementing VR lessons as a part of everyday classroom practice, this paper aims to provide practical ideas for educators to leverage on the affordances of virtual reality technologies to plan and design VR lessons. The author will also share sample lesson ideas on how educators can use VR 360 degrees videos to reach out to their students during this COVID-19 pandemic to complement the inquiry learning experience. The immersive and interactive nature of VR makes it an ideal tool for differentiated instruction to cater to diverse learners and learning needs especially during this pandemic. Data from findings using grounded theory and quantitative studies on affective outcomes show that there is significant increase in students' enjoyment in learning science when immersive VR is used and that the use of immersive VR increases students' self-efficacy. These findings have implications on the pedagogical design of lessons that use immersive VR. [For the full proceedings, see ED622227.]

In view of the present situation that the exhaust waste heat of the hot air hood in the paper drying section is too much and the environment is not friendly, a closed heat pump drying system model applied to the exhaust air hood is proposed and established. Effects of evaporation temperature and condensation temperature on supply air temperature, supply air moisture content, system performance coefficient (COP) and dehumidification energy consumption ratio (SMER) were studied. Results show that with the increase of condensation temperature, the supply air temperature is unchanged, and the moisture content of the supply air increase, while the COP and SMER of the system show a downward trend. The moisture content of supply air decrease with the increase of evaporation temperature, while the supply air temperature, COP and SMER all show an upward trend. Therefore, in order to improve the drying characteristics and improve the performance of the heat pump system, the condensation temperature can be reduced and the evaporation temperature can be increased.
