The study evaluates how smart nanoparticles affect beam structural performance while using computational resources hosted on remote servers. An enhanced advanced adaptive harmony search algorithm (AAHS) serves to boost optimization efficiency levels. The algorithm makes two sequential parameter adjustment stages which start by adapting harmony memory through variable bandwidth methods and proceed with adaptive step-size implementations. The research investigates the best design parameters for ZnO nanoparticle reinforced nanocomposite sinusoidal beams under different axial force and foundation property conditions and applied voltage levels. Results show that the proposed AAHS method outperforms alternative optimization methods according to comparative research. Under 50 GPa buckling force and 100 V applied voltage the optimal beam should have L/h ratio of 4.425 together with 118 GPa foundation spring constant, 29 Pa shearing constant and 0.055 ZnO nanoparticle volume fraction. The study demonstrates that all three factors namely applied voltage, buckling force and foundation stiffness critically affect optimization of beams.

computer simulation was utilized to characterize the electrophoretic processes occurring during the enantioselective capillary electrophoresis-mass spectrometry (CE-MS) analysis of ketamine, norketamine, and hydroxynorketamine in a system with partial filling of the capillary with 19 mM (equals 5%) of highly sulfated gamma-cyclodextrin (HS-gamma-CD) and analyte detection on the cathodic side. Provided that the sample is applied without or with a small amount of the chiral selector, analytes become quickly focused and separated in the thereby formed HS-gamma-CD gradient at the cathodic end of the sample compartment. This gradient broadens with time, remains stationary, and gradually reduces its span from the lower side due to diffusion such that analytes with high affinity to the anionic selector become released onto the other side of the focusing gradient where anionic migration and defocusing occur concomitantly. The analytes that remain focused until the migrating HS-gamma-CD concentration boundary arrives at the cathodic end of the sample compartment become gradually released into the cathodic part and migrate in the absence of HS-gamma-CD toward the detector. This behavior is dependent on the length of the HS-gamma-CD zone in the cathodic part of the electrophoretic column, the initial sample zone length, and the sample matrix. The data presented reveal the possibility that only one of the enantiomers of an analyte migrates toward the detector, whereas the other is lost for the analysis, or that both enantiomers migrate toward the cathode but do not separate. Enantiomer separation followed by migration toward the cathode can only be achieved for analytes with rather low complexation constants, such as hydroxynorketamine assessed in this work, and is dependent on the slope of the HS-gamma-CD focusing gradient. The gained insights illustrate that dynamic simulation is an indispensable tool to investigate electrophoretic processes of complex systems.

Increasing requests for thickened fluid food are demanded with population aging, while the limited information provided by the International Dysphagia Diet Standardisation Initiative (IDDSI) is insufficient for food development. Recently, the introduction of computer simulation seems to be able to overcome this dilemma. Here, a thickened fluid system (xanthan gum and konjac glucomannan, XG and KGM) at different ratios was kept at the same IDDSI level 3. An obvious synergy was observed in the ratio of 1:9 (XG: KGM) with high surface tension, zero-shear viscosity, firmness and cohesion, and thus was used to prepare the brown rice paste. From computer simulation, the brown rice pastes (0.3 % and 0.5 % thickener) splashed and that with higher thickener content resulted in more residue. The thickener content of 0.7 % provided enough viscosity and cohesion to avoid splash, and most of the bolus flowed consistently, showing the best sensory quality and swallowing properties.

In this study, the effect of non-thermal effects of alternating electric field (AEF) treatment on hemp seed protein (HSP) was investigated, focus on the effect of different electric field strengths and reaction times as independent variables on the structure of HSP. The structural properties of HSP were the main focus, and the functional properties were supplemented to explore the modification effect of the AEF treatment on HSP. Multispectroscopic analysis revealed that the AEF-treated HSP (AEF-HSP) had a lower alpha-helix and beta-sheet content. In the determination of endogenous fluorescence spectroscopy, synchronous fluorescence spectroscopy, and 3D fluorescence spectroscopy, the hydrophobic amino acid residues were discovered to be exposed to the microenvironment, and the maximum fluorescence intensity was found to occur at an electric field strength of 6 V/ cm and a reaction time of 60 min. Moreover, the solubility and contact angle of AEF-HSP were also investigated, and revealed that the presence of an AEF effectively promoted the solubility of HSP. Meanwhile, the electrical effects generated during the AEF treatment were specifically computer simulated to explore the distribution and diffusion of non-thermal effects. The overall study is of great significance in promoting the reuse of HSP, a byproduct of hemp processing.

This paper proposes an innovative flood control simulation and early warning system integrating computer simulation and building information modeling (BIM). The system combines deep learning technology with water flow simulation, uses long short-term memory network (LSTM) to model and predict historical water level data, and combines the three-dimensional terrain information provided by the BIM model to dynamically evaluate the water flow and flood spread risks. Through this innovative algorithm, the system can achieve accurate flood prediction according to different scenarios and conditions, and improve the timeliness and accuracy of early warning. In the experimental part, a reservoir was used as a case for verification. The results showed that the LSTM-based algorithm improved the prediction accuracy by $\mathbf{2 0 \%}$ compared with the traditional regression prediction method, and the computational efficiency was improved by 15 %. Compared with traditional methods, the water conservancy flood control early warning system integrating BIM and deep learning is more stable and efficient under complex terrain. This study provides new ideas for intelligent decision-making in the field of water conservancy and flood control. It is not only highly practical, but also provides technical support for further promoting intelligent water conservancy management and disaster prevention and control.

This paper proposes an automated evaluation system for news communication effect based on computer simulation, aiming to realize real-time analysis and optimization of news communication through big data technology. The system designs a communication effect evaluation model based on big data, combines the dynamic changes in the information dissemination process, and simulates the dissemination path and effect of different news content in different audience groups. The automated process is used to simulate the effect of news dissemination in multiple dimensions, and analyzes the impact of different dissemination strategies on audience participation, dissemination scope and information feedback. The simulation results are processed by data analysis tools to show the differences in the dissemination effects of different news content on various platforms, and provide quantitative evaluation indicators. The experimental results show that the evaluation system based on big data has significant advantages in improving the accuracy of news dissemination analysis. It can generate dissemination effect reports in real time and show data changes such as 30% increase in audience participation and 15% expansion of information dissemination scope under different strategies. This provides scientific decision-making support for news publishers and media managers.

Introduction: Radiographers support the multidisciplinary team by facilitating medical imaging within the operating theatre environment. This project aimed to enhance student readiness for clinical competency in operative theatre imaging by implementing an authentic C-arm simulator for students to use prior to attending clinical placement. Methods: This study followed a pre-post, quantitative study design. *** (c) CA is a computer simulation software which allows users to produce radiographic images using a virtual 'C-arm' imaging scanner, within a 3D operating theatre environment. Educational workshops were followed by Likertscale surveys to ascertain perspectives relating to student satisfaction, engagement, knowledge and skill enhancement, and reflections on behavioral changes following engagement with the simulator. Results: The post-simulator survey demonstrated favourable scores were favourable in terms of student enjoyment (94 % agreed or strongly agreed), skill development (94 %), anatomical knowledge (63 %), operation of the machine (94 %) and its relevance to the radiographer's role (100 %) and professional capabilities (87 %). Most students found the program's instructions to be straightforward (81 %). Questions relating to confidence also demonstrated favourable results, with students highlighting perceived greater confidence in their abilities (87 %) and the theatre environment (61 %). When asked whether the C-Arm simulator is just as effective as hands-on placement experiences, 50 % of participants disagreed or strongly disagreed with this statement. Conclusion: The C-arm simulator enabled our students to engage in authentic, scenario-based cases within simulated settings, mirroring conditions encountered in clinical practice. Overall, the findings highlight positive levels of perceived development and satisfaction. Future studies should evaluate objective knowledge and skill development within the clinical setting. Implications for practice: S

The results of studies carried out using a computer programme simulating the coagulation of suspensions containing spherical sol particles and spherical coagulant particles are *** influence of the degree of dispersion of the system on the coagulation reaction kinetics was investigated. The obtained results of kinetic studies were tested in the light of classical Müller–Smoluchowski equations. The influence of the physical properties of the coagulant,such as size, density and mass, on the coagulation rate was tested. It was found that within the range described in this paper, the rate of the simulated coagulation process fulfils both the kinetic equation of a first-order reaction, and the kinetic equation of a second-order *** the tested range, a significant influence of the mass and size of the coagulant on the coagulation rate was ascertained. The kinetic Müller–Smoluchowski dependence is fulfilled in a broader range of the degree of dispersion, when the coagulant particle mass and the sol particle mass are equal. When the particle mass increases with an increase in the particle radius, the coagulation rate increases faster that it would result from the Müller's dependence.

To realize the technology of fabricating the rheologic semi-solid slurry of ZL112Y aluminum alloy via continues electromagnetic stirring process, ANSYS software was used to simulate electromagnetic force field and fluid velocity field in the alloy melt in a crucible tube in three coils. In the first section of the paper, eletromagnetic force field and fluid velocity field caused by single coil were simulated. The result of this simulation gives an average velocity of 3.2 cm/s and it is called critical velocity because a fluid velocity over it will cause a fine and spherical structure of solid primary a in a semi-solid melt. And, from this result, a reasonable temperature of semi-solid of the alloy and an electrical current intensity were established. The electrical current intensity of the result of this simulation corresponded to the current intensity used in a practice experiment, in which the primary α was obviously refined and sphericized. Based on this simulation of single coil electromagnetic stirring, in the second section of the paper, eletromagnetic force field and fluid velocity field caused by three coils were simulated. The result of the simulation shows that, 1) there is a semi-solid zone of 32 mm from bottom of the crucible tube to the upper; 2) the electrical current intensities of three coils of 400 A, 600 A, and 400 A, which were set to top range, middle range and bottom range of the tube, respectively, were the optimum parameters of electromagnetic current intensity under the condition of this investigation; and 3) under effect of these electromagnetic current intensity, the fluid velocities of the melt in the tube were 6.3 cm/s in top range, 3.75 cm/s in middle range, and 3.9 cm/s in bottom range of it, respectively.

A systematical simulation has been carried out on the indentation creep test on particle-reinforced composites. The deformation, failure mechanisms and life are analyzed by three reasonable models. The following five factors have been considered simultaneously: creep property of the particle, creep property of the matrix, the shape of the particle, the volume fraction of the particle and the size (relative size to the particle) of the indentation indenter. For all the cases, the power law respecting to the applied stress can be used to model the steady indentation creep depth rate of the indenter, and the detail expressions have been presented. The computer simulation precision is analyzed by the two-phase model and the three-phase model. Two places of the stress concentration are found in the composites. One is ahead of the indentation indenter, where the high stress state is deduced by the edge of the indenter and will decrease rapidly near to a steady value with the creep time. The other one is at the interface, where the high stress state is deduced by the misfit of material properties between the particles and matrix. It has been found that the creep dissipation energy density other than a stress parameter can be used to be the criterion to model the debonding of the interfaces. With the criterion of the critical creep dissipation energy density, a power law to the applied stress with negative exponent can be used to model the failure life deduced by the debonding of interfaces. The influences of the shape of the particles and the matching of creep properties of particle and matrix can be discussed for the failure. With a crack model, the further growth of interface crack is analyzed, and some important experimental phenomena can be predicted. The failure mechanism which the particle will be punched into matrix has been also discussed. The critical differences between the creep properties of the particles and matrix have been calculated, after a parameter has b
