Examination of Internal Defects in the Casting Process by Using a Scanning Electron Microscopy
Abstract: In today's manufacturing landscape, stringent requirements and specifications for mechanical properties and other characteristics have become crucial for top casting manufacturers. This paper focuses on using Scanning Electron Microscopy (SEM) as a powerful tool to analyze internal defects that significantly impact the performance of castings. Specifically, it delves into various aspects of this approach, including the identification of bifilm deficiencies in ductile and chromium cast iron, near-surface corrosion induced by …

Experimental Investigation of Bearing Inner and Outer Wall Defects by Ultrasonic Waves
Abstract: Sometimes the bearings show their defects by exchanging between the network gears, and this can be useful for experimental and similar experiments. These defects will cause the bearing to malfunction, the bearing to malfunction and need to be repaired and maintained, which can be useful for the industry and save potential costs. These defects can be significant through ultrasound to combine time and frequency variables, which is addressed in this …

Optimization Techniques for Battery Health Monitoring and Management
Abstract: The "IoT-Based Battery Management System" project represents an innovative solution to address the growing demand for efficient and intelligent battery monitoring and management across various applications. In order to achieve maximum efficiency from a multi-cell Li-ion battery, every cell inside the battery must be "matched." Most battery safety and qualification standards demand that a battery be built entirely of compatible cells. Still, not much work is done to ensure that …

Investigating Pipeline Integrity Failure as a Result of Corrosion
Abstract: The study reviewed different failure factors and data of onshore crude oil pipelines covering corrosion, external interference, structural defects, and operators’ errors. The focus of this research is to identify factors affecting failure of crude oil pipelines in Nigeria due to corrosion with analysis of failure data from 2008–2017. Corrosion (internal and external) over total length of available pipelines for each year was analysed to determine the current mean time …

Fault Location in Two Phase Traction System
Abstract: Owing to the installation of autotransformers at regular intervals along the line, distance protection relays cannot be used with the aim of locating ground faults in 2×25 kV railway power supply systems. The reason is that the ratio between impedance and distance to the fault point is not linear in these electrification systems, unlike in 1×25 kV power systems. Therefore, the location of ground faults represents a complicated task in …

A Close-Packed Tri-Band Multi- Input Multi- Output Antenna System With DGS
Abstract: ABSTRACTIn this manuscript, A Close-packed tri-band multi input multi output antenna system with defective Ground structure for Electronic countermeasure application is proposed. Two monopoles are placed on the one end of the PCB and spaced 10mm apart. Near field of two identical monopoles creates mutual coupling that is reduced by placing metal strip (2x19) mm2 on the ground plane. The Projected Wang-formed DGS (Defective Ground Structure) of size (20x16) mm2 …

Review of Feature Selection Methods and Semi Supervised Feature Selection Algorithms for Classification
Abstract: Current evolution in technology has resulted in tremendous growth of data with respect to dimensionality and sample size. Knowledge discovery from these high dimensional data are becoming cumbersome. Though powerful machine learning algorithms are prevalent, noisy data, imperfect sensing and collection of data leads to poor and defective knowledge discovery. Noise and redundant features cannot be circumvented due to which data collection process is biased. Dimensionality reduction techniques namely feature …

Hardware Protection of Design Data for Integrated Circuits: A Review
Abstract: Due to globalization of integrated circuit (IC) design flow, the supply chain elements can pirate ICs, overbuild ICs and insert hardware Trojans. Ending piracy of ICs is locked by inserting additional keys and only a correct key makes the design to produce correct outputs. Test of ICs is essential to ensure their quality; the test is meant to prevent defective ICs from entering into the supply chain. Due to the …

Gene Editing: Rewriting the Life and Consequences
Abstract: ABSTRACTGene editing is the rational, precise and candid modification of DNA sequences or genes in living cells and organisms, literally for anything and everything possible. Its manifestation ranging from designing disease resistant crops or therapeutic correction of defective genes responsible for myriad of debilitating diseases in human beings to reprogramming of organisms that can produce new sophisticated and potent biologicals. The possible implication of gene editing is wide ranging and …
