The reason of this lack of attention lies mainly in the fact that CFD simulations typically take large periods of time to complete, and their results would thus not be available in time to be of use during an emergency. Firefighters often face uncertain conditions when entering a building to attack a fire. They would greatly benefit from a technology based on predictive fire simulations, able to assist their decision-making process. The principal constraint to faster CFD simulations is the fine grid necessary to solve accurately the physical processes that govern a fire. This paper explores the possibility of overcoming this constraint and using coarse grid CFD simulations for fire scenarios, and proposes a methodology to use the simulation results in a meaningful way that can be used by the fire fighters during an emergency. Data from real scale compartment fire tests were used to compare CFD fire models with different grid arrangements, and empirical correlations were obtained to interpolate data points into the grids. The results show that the strongly predominant effect of the heat release rate of the fire on the fluid dynamics allows for the use of coarse grids with relatively low overall impact of simulation results. Simulations with an acceptable level of accuracy could be run in real time, thus making them useful as a forecasting tool for emergency response purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20simulations" title=" fire simulations"> fire simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20response" title=" emergency response"> emergency response</a>, <a href="https://publications.waset.org/abstracts/search?q=forecast" title=" forecast"> forecast</a> </p> <a href="https://publications.waset.org/abstracts/50382/coarse-grid-computational-fluid-dynamics-fire-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50382.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1928</span> Numerical Simulations for Nitrogen Flow in Piezoelectric Valve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawel%20Flaszynski">Pawel Flaszynski</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Doerffer"> Piotr Doerffer</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Holnicki-Szulc"> Jan Holnicki-Szulc</a>, <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Mikulowski"> Grzegorz Mikulowski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Results of numerical simulations for transonic flow in a piezoelectric valve are presented.

Critical thinking is essential in providing safe, competent, and skillful nursing interventions. Educational institutions must provide a curriculum that improves nursing students' critical thinking abilities. In addition, the recent pandemic resulted in nursing students who previously received in-person clinical but now most clinical has been converted to remote learning, increasing the use of simulations. Unfolding medium and high-fidelity simulations and Socratic questioning are used in many simulations debriefing sessions. Methodology: Google Scholar was researched with the keywords: critical thinking of nursing students with unfolding simulation, which resulted in 22,000 articles; three were used. A second search was implemented with critical thinking of nursing students Socratic questioning, which resulted in two articles being used. Conclusion: Unfolding simulations increase nursing students' critical thinking, especially during the briefing (pre-briefing and debriefing) phases, where most learning occurs. In addition, the use of Socratic questions during the briefing phases motivates other questions, helps the student analyze and critique their thinking, and assists educators in probing students' thinking, which further increases critical thinking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=briefing" title="briefing">briefing</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title=" critical thinking"> critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=Socratic%20thinking" title=" Socratic thinking"> Socratic thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=unfolding%20simulations" title=" unfolding simulations"> unfolding simulations</a> </p> <a href="https://publications.waset.org/abstracts/146324/unfolding-simulations-with-the-use-of-socratic-questioning-increases-critical-thinking-in-nursing-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146324.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1925</span> Simulations of a Jet Impinging on a Flat Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reda%20Mankbadi">Reda Mankbadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we explore the use of a second-order unstructured-grid, finite-volume code for direct noise prediction.

The ANSYS Fluent commercial code is utilized for the calculations. The acoustic field is obtained directly from the simulations and is compared with the integral approach of Ffowcs Williams-Hawkings (FWH). Results indicate the existence of a preferred radiation angle. The spectrum obtained is in good agreement with observations.

To do so, we develop the general equilibrium model with ICT investment, obtain the equilibrium solutions, and then simulate the model with these solutions for some OECD countries. As a result, generally, during the corresponding periods we confirm that the relationship between ICT investment and income inequality is positive. In this mode, the increment of the ratio of ICT investment to the aggregated investment in stock enhances the capital’s share of income, and finally leads to income inequality such as the increase of the share of the top decile income. Although we confirm the positive relationship between ICT investment and income inequality, the upward trend for that relationship depends on the values of parameters for the making use of the simulations and these parameters are not deterministic in the magnitudes on the calculated results for the simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ICT" title="ICT">ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=inequality" title=" inequality"> inequality</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20accumulation" title=" capital accumulation"> capital accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/82723/the-role-of-ict-for-income-inequality-the-model-and-the-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1919</span> Amyloid-β Fibrils Remodeling by an Organic Molecule: Insight from All-Atomic Molecular Dynamics Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikhil%20Agrawal">Nikhil Agrawal</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20A.%20Skelton"> Adam A.

To disrupt the remodeling of Aβ fibrils, a number of candidate molecules have been proposed. To study the molecular mechanisms of Aβ fibrils remodeling we performed a series of all-atom molecular dynamics simulations, a total time of 3µs, in explicit solvent. Several previously undiscovered candidate molecule-Aβ fibrils binding modes are unraveled; one of which shows the direct conformational change of the Aβ fibril by understanding the physicochemical factors responsible for binding and subsequent remodeling of Aβ fibrils by the candidate molecule, open avenues into structure-based drug design for AD can be opened. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alzheimer%E2%80%99s%20disease" title="alzheimer’s disease">alzheimer’s disease</a>, <a href="https://publications.waset.org/abstracts/search?q=amyloid" title=" amyloid"> amyloid</a>, <a href="https://publications.waset.org/abstracts/search?q=MD%20simulations" title=" MD simulations"> MD simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=misfolded%20protein" title=" misfolded protein"> misfolded protein</a> </p> <a href="https://publications.waset.org/abstracts/52879/amyloid-v-fibrils-remodeling-by-an-organic-molecule-insight-from-all-atomic-molecular-dynamics-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52879.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1918</span> An Interpolation Tool for Data Transfer in Two-Dimensional Ice Accretion Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Cordero-Gracia">Marta Cordero-Gracia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariola%20Gomez"> Mariola Gomez</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Blesbois"> Olivier Blesbois</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Carrion"> Marina Carrion</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the difficulties in icing simulations is for extended periods of exposure, when very large ice shapes are created. As well as being large, they can have complex shapes, such as a double horn. For icing simulations, these configurations are currently computed in several steps. The icing step is stopped when the ice shapes become too large, at which point a new mesh has to be created to allow for further CFD and ice growth simulations to be performed. This can be very costly, and is a limiting factor in the simulations that can be performed. A way to avoid the costly human intervention in the re-meshing step of multistep icing computation is to use mesh deformation instead of re-meshing. The aim of the present work is to apply an interpolation method based on Radial Basis Functions (RBF) to transfer deformations from surface mesh to volume mesh. This deformation tool has been developed specifically for icing problems. It is able to deal with localized, sharp and large deformations, unlike the tools traditionally used for more smooth wing deformations. This tool will be presented along with validation on typical two-dimensional icing shapes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ice%20accretion" title="ice accretion">ice accretion</a>, <a href="https://publications.waset.org/abstracts/search?q=interpolation" title=" interpolation"> interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20deformation" title=" mesh deformation"> mesh deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20functions" title=" radial basis functions"> radial basis functions</a> </p> <a href="https://publications.waset.org/abstracts/59130/an-interpolation-tool-for-data-transfer-in-two-dimensional-ice-accretion-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59130.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1917</span> A Knee Modular Orthosis Design Based on Kinematic Considerations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Copilusi">C.

In contrast, ab initio molecular dynamics (AIMD) provides high precision by solving the Kohn–Sham equations yet requires significant computational resources, restricting the size of systems and time scales that can be simulated. To address these challenges, we employed NequIP, a machine learning model based on an E(3)-equivariant graph neural network, to accelerate molecular dynamics simulations of a 1M LiPF6 in EC/EMC (v/v 3:7) for Li battery applications. AIMD calculations were initially conducted using the Vienna Ab initio Simulation Package (VASP) to generate highly accurate atomic positions, forces, and energies. This data was then used to train the NequIP model, which efficiently learns from the provided data. NequIP achieved AIMD-level accuracy with significantly less training data. After training, NequIP was integrated into the LAMMPS software to enable molecular dynamics simulations of larger systems over longer time scales. This method overcomes the computational limitations of AIMD while improving the accuracy limitations of CMD, providing an efficient and precise computational framework. This study showcases NequIP’s applicability to electrolyte systems, particularly for simulating the dynamics of LiPF6 ionic mixtures. The results demonstrate substantial improvements in both computational efficiency and simulation accuracy, highlighting the potential of machine learning models to enhance molecular dynamics simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20batteries" title="lithium-ion batteries">lithium-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolyte%20simulation" title=" electrolyte simulation"> electrolyte simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics" title=" molecular dynamics"> molecular dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a> </p> <a href="https://publications.waset.org/abstracts/192137/accelerating-molecular-dynamics-simulations-of-electrolytes-with-neural-network-bridging-the-gap-between-ab-initio-molecular-dynamics-and-classical-molecular-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192137.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">18</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1915</span> The Evolution of the Simulated and Observed Star Formation Rates of Galaxies for the Past 13 Billion Years</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonios%20Katsianis">Antonios Katsianis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> I present the evolution of the galaxy Star Formation Rate Function (SFRF), star formation rate-stellar mass relation (SFR-M*) and Cosmic Star Formation Rate Density (CSFRD) of z = 0-8 galaxies employing both the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations and a compilation of UV, Ha, radio and IR data.

For dynamic energy simulations at city and district level, this paper provides an overview of the available GIS data models and their levels of detail.

As a result, their material properties would be degraded by water absorption. A full characterization of the material properties under hygrothermal conditions requires time- and cost-consuming experimental tests. To gain insights into the physics of diffusion mechanisms, atomistic simulations have been shown to be effective tools. Concerning the diffusion of water in polymers, spatial trajectories of water molecules are obtained from molecular dynamics (MD) simulations allowing the interpretation of diffusion pathways at the nanoscale in a polymer network. Conventional MD simulations of water diffusion in amorphous polymers lead to discrepancies at low temperatures due to the short timescales of the simulations. In the proposed model, this issue is solved by using a combined scheme of autonomous basin climbing (ABC) with kinetic Monte Carlo and reactive MD simulations to investigate the diffusivity of water molecules in epoxy resins across a wide range of temperatures. It is shown that the proposed simulation framework estimates kinetic properties of water diffusion in epoxy resins that are consistent with experimental observations and provide a predictive tool for investigating the diffusion of small molecules in other amorphous polymers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resins" title="epoxy resins">epoxy resins</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20diffusion" title=" water diffusion"> water diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20basin%20climbing" title=" autonomous basin climbing"> autonomous basin climbing</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic%20Monte%20Carlo" title=" kinetic Monte Carlo"> kinetic Monte Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20molecular%20dynamics" title=" reactive molecular dynamics"> reactive molecular dynamics</a> </p> <a href="https://publications.waset.org/abstracts/146647/water-diffusivity-in-amorphous-epoxy-resins-an-autonomous-basin-climbing-based-simulation-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146647.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1912</span> Effect of Hydroxyl Functionalization on the Mechanical and Fracture Behaviour of Monolayer Graphene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akarsh%20Verma">Akarsh Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Avinash%20Parashar"> Avinash Parashar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this article is to study the effects of hydroxyl functional group on the mechanical strength and fracture toughness of graphene.

In particular, the transition pressure to the rock-salt phase is calculated and the results are compared with other available works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gallium%20compounds" title="Gallium compounds">Gallium compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulations" title=" molecular dynamics simulations"> molecular dynamics simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=interatomic%20potential%20thermodynamic%20properties" title=" interatomic potential thermodynamic properties"> interatomic potential thermodynamic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20phase%20transition" title=" structural phase transition"> structural phase transition</a> </p> <a href="https://publications.waset.org/abstracts/18854/molecular-dynamics-simulations-of-the-structural-elastic-and-thermodynamic-properties-of-cubic-gabi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18854.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1908</span> Drama in the Classroom: Work and Experience with Standardized Patients and Classroom Simulation of Difficult Clinical Scenarios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliyah%20Dosani">Aliyah Dosani</a>, <a href="https://publications.waset.org/abstracts/search?q=Kerri%20Alderson"> Kerri Alderson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two different simulations using standardized patients were developed to reinforce content and foster undergraduate nursing students’ practice and development of interpersonal skills in difficult clinical situations in the classroom. The live actor simulations focused on fostering interpersonal skills, traditionally considered by students to be simple and easy. However, seemingly straightforward interactions can be very stressful, particularly in women’s complex social/emotional situations. Supporting patients in these contexts is fraught with complexity and high emotion, requiring skillful support, assessment and intervention by a registered nurse. In this presentation, the personal and professional perspectives of the development, incorporation, and execution of the live actor simulations will be discussed, as well as the inclusion of student perceptions, and the learning gained by the involved faculty. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adult%20learning" title="adult learning">adult learning</a>, <a href="https://publications.waset.org/abstracts/search?q=interpersonal%20skill%20development" title=" interpersonal skill development"> interpersonal skill development</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20learning" title=" simulation learning"> simulation learning</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20learning" title=" teaching and learning"> teaching and learning</a> </p> <a href="https://publications.waset.org/abstracts/120576/drama-in-the-classroom-work-and-experience-with-standardized-patients-and-classroom-simulation-of-difficult-clinical-scenarios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120576.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1907</span> Coarse-Graining in Micromagnetic Simulations of Magnetic Hyperthermia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Razyeh%20Behbahani">Razyeh Behbahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20L.%20Plumer"> Martin L.

With the goal to effectively simulate room-temperature loops for large iron-oxide based systems at relatively slow sweep rates on the order of 1 Oe/ns or less, a coarse-graining scheme is proposed and tested. The scheme is derived from a previously developed renormalization-group approach. Loops associated with nanorods, used as building blocks for larger nanoparticles that were employed in preclinical trials (Dennis et al., 2009 Nanotechnology 20 395103), serve as the model test system. The scaling algorithm is shown to produce nearly identical loops over several decades in the model grain sizes. Sweep-rate scaling involving the damping constant alpha is also demonstrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coarse-graining" title="coarse-graining">coarse-graining</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperthermia" title=" hyperthermia"> hyperthermia</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis%20loops" title=" hysteresis loops"> hysteresis loops</a>, <a href="https://publications.waset.org/abstracts/search?q=micromagnetic%20simulations" title=" micromagnetic simulations"> micromagnetic simulations</a> </p> <a href="https://publications.waset.org/abstracts/112852/coarse-graining-in-micromagnetic-simulations-of-magnetic-hyperthermia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112852.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1906</span> Information Exchange Process Analysis between Authoring Design Tools and Lighting Simulation Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudan%20Xue">Rudan Xue</a>, <a href="https://publications.waset.org/abstracts/search?q=Annika%20Moscati"> Annika Moscati</a>, <a href="https://publications.waset.org/abstracts/search?q=Rehel%20Zeleke%20Kebede"> Rehel Zeleke Kebede</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Johansson"> Peter Johansson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Successful buildings’ simulation and analysis inevitably require information exchange between multiple building information modeling (BIM) software. The BIM infor-mation exchange based on IFC is widely used.

In this research, interviews with lighting simulation experts and a case study provided by a company producing lighting devices have been the research methods used to identify the necessary steps and data for suc-cessful information exchange between lighting simulation tools and authoring design tools.

Existing knowledge about phenomena occurring in the MOVPE process allows to produce high quality nitride based semiconductors. However, process parameters of MOVPE reactors can vary in certain ranges. Main goal of this study is optimization of the process and improvement of the quality of obtained crystal. In order to investigate this subject a series of computer simulations have been performed. Numerical simulations of heat and mass transfer in GaN epitaxial growth process have been performed to determine growth rate for various mass flow rates and pressures of reagents. According to the fact that it’s impossible to determine experimentally the exact distribution of heat and mass transfer inside the reactor during the process, modeling is the only solution to understand the process precisely. Main heat transfer mechanisms during MOVPE process are convection and radiation. Correlation of modeling results with the experiment allows to determine optimal process parameters for obtaining crystals of highest quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Finite%20Volume%20Method" title="Finite Volume Method">Finite Volume Method</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductors" title=" semiconductors"> semiconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=epitaxial%20growth" title=" epitaxial growth"> epitaxial growth</a>, <a href="https://publications.waset.org/abstracts/search?q=metalorganic%20vapor%20phase%20epitaxy" title=" metalorganic vapor phase epitaxy"> metalorganic vapor phase epitaxy</a>, <a href="https://publications.waset.org/abstracts/search?q=gallium%20nitride" title=" gallium nitride"> gallium nitride</a> </p> <a href="https://publications.waset.org/abstracts/19033/finite-volume-method-simulations-of-gan-growth-process-in-movpe-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19033.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1904</span> Optimization of the Numerical Fracture Mechanics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Hentati">H.

Molecular Dynamics can be used to simulate, e.g., the binding and unbinding event of a small drug-like molecule with regard to the active site of an enzyme or a receptor. However, the time-scale of the overall binding event is many orders of magnitude longer than the time-scale of simulation. Thus, there is a need to speed-up molecular simulations. In order to speed up simulations, the molecular dynamics trajectories have to be ”steared” out of local minimizers of the potential energy surface – the so-called metastabilities – of the molecular system. Increasing the kinetic energy (temperature) is one possibility to accelerate simulated processes. However, with temperature the entropy of the molecular system increases, too. But this kind ”stearing” is not directed enough to stear the molecule out of the minimum toward the saddle point. In this article, we give a new mathematical idea, how a potential energy surface can be changed in such a way, that entropy is kept under control while the trajectories are still steared out of the metastabilities. In order to compute the unsteared transition behaviour based on a steared simulation, we propose to use extrapolation methods. In the end we mathematically show, that our method accelerates the simulations along the direction, in which the curvature of the potential energy surface changes the most, i.e., from local minimizers towards saddle points. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extrapolation" title="extrapolation">extrapolation</a>, <a href="https://publications.waset.org/abstracts/search?q=Eyring-Kramers" title=" Eyring-Kramers"> Eyring-Kramers</a>, <a href="https://publications.waset.org/abstracts/search?q=metastability" title=" metastability"> metastability</a>, <a href="https://publications.waset.org/abstracts/search?q=multilevel%20sampling" title=" multilevel sampling"> multilevel sampling</a> </p> <a href="https://publications.waset.org/abstracts/67617/accelerated-molecular-simulation-a-convolution-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67617.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1902</span> Evaluating Hourly Sulphur Dioxide and Ground Ozone Simulated with the Air Quality Model in Lima, Peru</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Od%C3%B3n%20R.%20S%C3%A1nchez-Ccoyllo">Odón R.

The objective of this research is to evaluate the effectiveness of the air-quality-WRF-Chem model with a horizontal resolution of 5 km x 5 km. For this purpose, the measurements of the hourly SO₂ and O₃ concentrations available in three air quality monitoring stations in Lima, Peru were used for the purpose of validating the simulations of the SO₂ and O₃ concentrations obtained with the WRF-Chem model in February 2018. For the quantitative evaluation of the simulations of these gases, statistical techniques were implemented, such as the average of the simulations; the average of the measurements; the Mean Bias (MeB); the Mean Error (MeE); and the Root Mean Square Error (RMSE). The results of these statistical metrics indicated that the simulated SO₂ and O₃ values over-predicted the SO₂ and O₃ measurements. For the SO₂ concentration, the MeB values varied from 0.58 to 26.35 µg/m³; the MeE values varied from 8.75 to 26.5 µg/m³; the RMSE values varied from 13.3 to 31.79 µg/m³; while for O₃ concentrations the statistical values of the MeB varied from 37.52 to 56.29 µg/m³; the MeE values varied from 37.54 to 56.70 µg/m³; the RMSE values varied from 43.05 to 69.56 µg/m³. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground-ozone" title="ground-ozone">ground-ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=lima" title=" lima"> lima</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphur%20dioxide" title=" sulphur dioxide"> sulphur dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=WRF-chem" title=" WRF-chem"> WRF-chem</a> </p> <a href="https://publications.waset.org/abstracts/154756/evaluating-hourly-sulphur-dioxide-and-ground-ozone-simulated-with-the-air-quality-model-in-lima-peru" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154756.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1901</span> Experimental Validation of Computational Fluid Dynamics Used for Pharyngeal Flow Patterns during Obstructive Sleep Apnea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pragathi%20Gurumurthy">Pragathi Gurumurthy</a>, <a href="https://publications.waset.org/abstracts/search?q=Christina%20Hagen"> Christina Hagen</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Ulloa"> Patricia Ulloa</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20A.%20Koch"> Martin A.

Recently, numerical simulations have been used to better understand the mechanism of pharyngeal collapse. However, to gain confidence in the solutions so obtained, an experimental validation is required. Therefore, in this study an experimental validation of computational fluid dynamics (CFD) used for the study of human pharyngeal flow patterns during OSA is performed. A stationary incompressible Navier-Stokes equation solved using the finite element method was used to numerically study the flow patterns in a computed tomography-based human pharynx model. The inlet flow rate was set to 250 ml/s and such that a flat profile was maintained at the inlet. The outlet pressure was set to 0 Pa. The experimental technique used for the validation of CFD of fluid flow patterns is phase contrast-MRI (PC-MRI). Using the same computed tomography data of the human pharynx as in the simulations, a phantom for the experiment was 3 D printed. Glycerol (55.27% weight) in water was used as a test fluid at 25°C. Inflow conditions similar to the CFD study were simulated using an MRI compatible flow pump (CardioFlow-5000MR, Shelley Medical Imaging Technologies). The entire experiment was done on a 3 T MR system (Ingenia, Philips) with 108 channel body coil using an RF-spoiled, gradient echo sequence. A comparison of the axial velocity obtained in the pharynx from the numerical simulations and PC-MRI shows good agreement. The region of jet impingement and recirculation also coincide, therefore validating the numerical simulations. Hence, the experimental validation proves the reliability and correctness of the numerical simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20validation" title=" experimental validation"> experimental validation</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20contrast-MRI" title=" phase contrast-MRI"> phase contrast-MRI</a>, <a href="https://publications.waset.org/abstracts/search?q=obstructive%20sleep%20apnea" title=" obstructive sleep apnea"> obstructive sleep apnea</a> </p> <a href="https://publications.waset.org/abstracts/67911/experimental-validation-of-computational-fluid-dynamics-used-for-pharyngeal-flow-patterns-during-obstructive-sleep-apnea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1900</span> Numerical Simulations of the Transition Flow of Model Propellers for Predicting Open Water Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huilan%20Yao">Huilan Yao</a>, <a href="https://publications.waset.org/abstracts/search?q=Huaixin%20Zhang"> Huaixin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Simulations of the transition flow of model propellers are important for predicting hydrodynamic performance and studying scale effects. In this paper, the transition flow of a model propeller under different loadings are simulated using a transition model provided by STAR-CCM+, and the influence of turbulence intensity (TI) on the transition, especially friction and pressure components of propeller performance, was studied. Before that, the transition model was applied to simulate the transition flow of a flat plate and an airfoil. Predicted transitions agree well with experimental results. Then, the transition model was applied for propeller simulations in open water, and the influence of TI was studied. Under the heavy and moderate loadings, thrust and torque of the propeller predicted by the transition model (different TI) and two turbulence models are very close and agree well with measurements. However, under the light loading, only the transition model with low TI predicts the most accurate results. Above all, the friction components of propeller performance predicted by the transition model with different TI have obvious difference. <p class="card-text"><strong>Keywords:</strong> <a
