This document summarizes a study that investigated the effect of wire-electro discharge machining (WEDM) process parameters on material removal rate and surface roughness when machining die steel D3. The study used a Taguchi design of experiments approach with three parameters (peak current, pulse-on time, and wire tension) each at three levels. The results showed that peak current had the greatest influence on both material removal rate and surface roughness, followed by pulse-on time, while wire tension had the least influence. Material removal rate and surface roughness both generally increased with increasing levels of the three parameters. The optimal combination of parameters was determined to maximize material removal rate while minimizing surface roughness.
Optimization of Wire Cut EDM of Aluminium Alloy 6063 by using Taguchi Techniqueijtsrd
The cold work applications like aluminium extrusion, it allows complex shapes to be formed with very smooth surfaces and it is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames should have high toughness, wear resistance, compressive strength, high corrosion resistance, high surface finish and complex profiles. AA 6063 is an aluminium alloy, with magnesium and silicon as the alloying elements. This material can satisfy the above requirements, because of its hardness and strength AA 6063 cannot be machined easily through traditional machining processes. Advanced machining processes are used only when there is no suitable traditional machining process to meet necessary requirements efficiently and economically. Among them wire cut EDM is employed because of its tight tolerances and high surface finish. Based on intense literature survey, it was noticed that very few works were reported on WEDM of AA 6063. As a part of our thesis, WEDM of AA 6063 is considered for the study. In this work Pulse on time, pulse off time, peak current, wire speed, wire tension and flushing pressure of dielectric medium are considered as parameters and their effect on performance measures, metal removal rate MRR and surface roughness will be studied through experimental investigation. Using Taguchi approach, considered parameters will be optimized for maximum MRR and minimum for Surface roughness separately. Taguchi method will be applied to generate mean S N ratios to identify the optimum process parameters. Kandukuri Srinivas | K. Anabayan | P. H. J.

Development of a Taguchi-based framework for optimizing two quality character...IJERA Editor
A framework based on Taguchi parameter design was developed and successfully demonstrated to optimize two
quality characteristics- surface roughness and angular accuracy in Wire Electrical Discharge Machining (WEDM)
process. An orthogonal array (OA)L9was used in the Taguchi experiment design for four controllable
factors, each with three levels. With one non-controllable factor investigated, 18 experiments were conducted in
the Taguchi-based experiment setting, compared to 3
4
(=81) parameter combination as required by a traditional
DOE setting. Conducted for the two response variables, Taguchi experiments from the case study gave the
optimal combination of pulse on time at 9µs (A1), feed rate at 35 in/min (B2), voltage at 8v (C2), and wire
tension at 165g (D3) for surface roughness optmization, and pulse on time at 13µs (A3), feed rate at 35 in/min
(B2), voltage at 8v (C2), and wire tension at 160g (D2) for angular accuracy optmization. This optimal parameter
setting combination was verified through a confirmation run that confirms the optimal quality responses of
126.1µin for surface roughness and 0.024º for angular accuracy. This research ultimately showed the dual
output variable improvement and the framework established itself as a means to solve similar problems in other
machining applications. The developed framework can serve as guidance for researchers to obtain multivariable
optimal setting in a systematic way.

A Comparative Study to Maximize MRR in Electro Discharge Machining Process by...IJERA Editor
Electro Discharge Machining (EDM) is a non-traditional machining process, based on thermo electric energy between the work piece and electrode. In this process, the material removal is occurred electro thermally by a series of successive discrete discharges between electrode and the work piece. Electro Discharge Machine which has the ability to machine hard, difficult to machine material and parts with internal complex shape by using precisely controlled sparks that occurs between electrode and work piece in the presence of dielectric fluid. This spark removes material from both work piece and electrode. Material Removal Rate (MRR) is of crucial importance in this process. In this research experiment has been done along with Copper and Graphite tool material as well as Mild Steel and Aluminium material has been used as work piece. Three major Parameters named as Electrode Speed (V), Current (I), and Depth of Cut (h) are considered to determine the MRR. In this experiment three levels of each parameter has been taken by using Taguchi L9 orthogonal array to find out the best combination of electrode and work piece at the optimal setting of control parameters for maximum Material Removal Rate.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

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.
