This research estimates the associated primary energy consumption for different combinations of dynamic switching energy for storage (J/bit), for processing (J/computation) and global computation intensity (computations/s). Bottom-up extrapolation is used. With ≈10 ronnacomputations/s in 2050, the J/computation should improve ≈36% per year from 2024 to 2050 to ≈50 attoJ/computation to keep computing processing energy flat. Also the dynamic switching energy needs a similar reduction rate to keep the computing processing energy flat. Hence, a paradigm shift is required to reduce the power used by computing. Technology could keep the use of primary energy flat if global computations and stored data grow slower than expected and especially if 50 aJ/computation and 1 nJ/bit can be delivered in 2050.

The aim of this project to create or to build a prototype solar tracking system to improve the performance of photo voltaic modules. The operation involves a continuous alignment of the photo voltaic modules with the sun rays to optimize the extraction of Sun’s energy or the conversion of Sun’s energy into Electrical Energy.The project involves developing of software for tracking through Microcontroller Unit. Two DC motors are used to get control in horizontal and vertical ones by using a Arduino Microcontroller Unit. Four LDR (Light Dependent Resistor) are used to collect the date of sun's intensity or irradiation.

This study focused on exploring sedimentation phenomena by developing a simplified theoretical model to analyze the mechanics of high-density spherical particles, specifically those with submicrometric sizes, as they deposit in homogeneous liquids. A theoretical equation was derived to quantify the relationship between the terminal velocity of these particles and their diameters. Simulation results revealed significant variations in terminal velocities among the examined particles. Specifically, particles with diameters of D1 = 10^-9 m, D2 = 10^-8 m, and D3 = 5 × 10^-8 m demonstrated terminal velocities of 0.073 m/s, 0.738 m/s, and 3.691 m/s, respectively. These findings suggest that even minor changes in particle size can lead to substantial differences in sedimentation rates, highlighting the critical role of particle diameter in sedimentation dynamics. This research contributes to a deeper understanding of sedimentation mechanisms at the nanoscale and has potential implications for various fields, including environmental science, materials engineering, and nanotechnology. The developed model not only quantifies sedimentation behavior but also serves as a foundational tool for future research aimed at optimizing the deposition processes of submicrometric particles in liquid mediums.

This article develops a theoretical model for the study of vibrating strings and resonance, which can be explored and discussed in the mutual study of Physics and Art. The results demonstrate that the equations obtained in this mathematical model can be used for activities that encompass a diversity of scientific concepts associated with everyday practices, highlighting the cultural relevance of Physics in modern society. After studying the concepts covered in the developed activities, it was observed that it is possible to work with the mathematical models applied in the interpretation of phenomena, even in scientific dissemination activities.
