Compressive strength (CS) of concrete is a key quality factor that is being monitored continuously in all construction projects which use huge quantity of concrete throughout the world. Engineers need to be open minded with the attitude of lifelonglearning to upskill with the ever-evolving softwareand hardware technologies. Seven day and twenty-eight-day compressive strengths of concrete samples with varied amounts of cement, blast furnace slag, fly ash, water, super plasticizer, coarse aggregate, and fine aggregate are studied. Multiple Linear Regression (MLR) models are fitted for this data in Microsoft Excel. Artificial Neural Networks (ANNs) in RStudio are developed for this data. The performances of both methods are compared. This paper takes care of Goal 12 of United Nations Sustainable Development of ensuring sustainable consumption and production patterns as environmentally degrading materials (flyash and blast furnace slag) are used.

AIP Conference Proceedings 2022年第1期2425卷

作者： A. Papargiri V. Kalantonis P. Vafeas M. Doschoris F. Kariotou G. Fragoyiannis 1Department of Electrical and Computer Engineering University of Patras 26504 Patras Greece 2Department of Chemical Engineering University of Patras 26504 Patras Greece 3Institute of Genetics and Biometry Leibniz Institute for Farm Animal Biology 18196 Dummerstorf Germany 4School of Science and Technology Hellenic Open University 26222 Patras Greece

The current research is focused on the study of the effect of head shape geometrical deformations to the solution of the forward electroencephalographic (EEG) problem and its sensitivity response. A novel and accurate analytical scheme has been developed by performing a perturbation analysis in the linear regime, where a homogenous three-shell spherical model, equipped with all the necessary mathematical tools, is introduced. The efficacy of the method is demonstrated by incorporating the numerical implementation of the obtained formulae in which both cases, with or without surface deviations, are presented and benchmarked. The suggested procedure provides us with a criterion, which recognizes whether surface perturbations will influence EEG recordings.

The paper focuses on the need for optical communication in future eras. Spatial reprocess cannot meet the present conditions with increasing traffic demand in Radio Frequency (RF) communication. The frequency spectrum in traditional methods of wireless communication has been saturated. Visible Light Communication (VLC) and Internet-of-Things (IoT) integration will open up many indoor applications in the near future. Light Emitting Diodes (LEDs) and Photodetectors (PDs) in VLC support reliable uplink and downlink for Device-to-Device communication indoors. There is emergence of the energy-efficient variant of the VLC due to the shortage of energy budget in the upcoming era. The VLC works well in low illuminance. Energy conservation is supportedby consuming much lower energy through the usage of LEDs in *** can be achieved through the hybrid of single and multicarrier modulation. The work is about to discuss dimming techniques that support VLC in low illuminance and multicarrier modulation, which supports high data rate transmission.

The aim of current Paper is to examine the effect/result of ‘heat source’ parameter over a wedge through porous-medium for electrically-conducting fluid flow for a magneto hydrodynamic Casson nanofluid with activation energy. The influence/impact of ‘second law’ analysis for electrically conducting fluid(s) with chemical-reaction also investigated. Dimension-less ordinary differential equations(ODE) are obtained/derived from the highly non- linear PDEs by using similarity transformations. The ‘Runge- Kutta –Fehlberg with shooting technique’ is utilized to solve remodelled ODEs numerically. The effect(s) of the ‘physical parameter’ on velocity, temperature and concentration are extensively discussed through several plots. Numerical result(s) for Nusselt number, skin friction coefficient & ‘Sherwood number’ for various parameter(s) are computed.

Proper recycling of garbage can be done easily if it is segregated prior to the recycling process. This project aims to present a smart garbage segregation system which segregates garbage into its respective type (wet waste, dry waste, metallic waste etc.) using different types of sensors and Arduino controller which takes care of all the task. The entire task is performed on a conveyor belt having multiple sections depending on number of types of wastes one wants to segregate. Waste is detected and directed to the respective slot or section for segregation. Then various piles of waste are created which are moved to their respective recycling units without much human effort.

An alternative source is growing in popularity with increasing global energy use and perceivable environmental degradation everywhere in the universe. The growth of wind farms necessitates system stability analysis, which incorporates dynamical distributed generation models. Doubly fed induction machines are widely used in the context of turbines of power higher than 1MW. However, direct-drive wind turbines that use synchronous generator principles have gained significant market penetration. This investigation implements a synchronous generator model using a frequency-based matrix converter with the assistance of an SVPWM method, which measures stator as grid voltage/current and analyses total THD. Converting the fluctuating voltages to something like a stable value using a frequency-based method is done with a matrix converter.

引用

AIP Conference Proceedings 2022年第1期2503卷

作者： Mikhail Loktev 1Laboratory of Computer Graphics V. A. Trapeznikov Institute of Control Sciences of Russian Academy of Sciences 65 Profsoyuznaya street Moscow 117997 Russia 2Department of Engineering Graphics Moscow State Technological University “STANKIN” Vadkovsky Pereulok 3a. 127055 Moscow Russia

The article discusses an approach to research in the field of interpore space analysis, which is primarily geometric in nature. The method of functional-voxel modeling is used as a basic geometric tool, since it allows you to form graphic M-images (model image) of any dimension. For the analytical representation of the geometry and Voronoi diagram of the model, the mathematical apparatus of R-functions (Rvachev functions) is used. A software implementation of the proposed approaches for constructing a Voronoi diagram in three-dimensional space will be presented.
