Evaluation of Fixed Base vs. Base Isolated Building SystemsIJERD Editor
This document compares the seismic performance of a 6-story building designed with a fixed base versus one with a base isolation system. It first describes the modeling and design of the fixed base building in ETABS and manually, where story drift was found to be the controlling factor. Member sizes of C45x45 columns and B45x35 beams were determined to satisfy demands. The modeling of the isolated building in ETABS used response spectrum analysis, with lateral forces much less than the fixed base building. The same member sizes were found to satisfy the reduced demands. Manual calculations of the seismic design parameters and story drift checks are shown for both the fixed base and isolated base buildings according to codes.

This document describes a photoelastic stress analysis of the bending strength of a helical gear. The analysis involved creating a 3D photoelastic model of the gear, subjecting it to loading, and freezing the stresses. Slices were cut from the model and observed under polarized light to determine stress distributions. Maximum bending stresses were calculated for different slices and scaled up to prototype values. Finite element analysis was also performed and showed good agreement with experimental results, with less than 2% variation in maximum stress values. The analysis found that helical gears experience higher peak bending stresses than spur gears due to their point contact loading.

Finite Element Analysis (FEA) is a numerical technique used to determine the behavior of complex geometries and systems. It breaks components down into finite elements in order to solve problems that cannot be solved through classical calculations. FEA provides outputs like stresses, strains, displacements and structural capacity that help evaluate a design. The FEA process involves preprocessing like creating a model and mesh, solving with applied loads and materials, and postprocessing the results. Models are simplified to reduce run time while ensuring accuracy of important features. FEA can be used to optimize designs before physical testing.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
