Future of semiconductor fabrication (fab) industries in india opportunities ...eSAT Journals
Abstract The peak demand of electronics products in India will reach several billions in forthcoming years. It has been always a dream of Electronics engineers in India to have a well structured manufacturing sector. At present a good number of companies are working in design but they don’t have their own fabrication facility here. The design projects which they are handling have larger dependency on foreign FABs. The country is a leading exporter of information technology service, including knowledge-intensive chip design under the EDA environment. India’s strength in chip design doesn’t help at all as we are lacking in wafer fabrication. Local electronics manufacturing remains disconnected from India’s chip design capabilities, research and development area. This has also affect the employment of electronics engineer as we have lacking in electronics manufacturing. India’s increasing domestic demand of electronics products results in rise in imports of final products and high dependency on key components/ICs. The manufacturing of semiconductor in India will only boost up with effective and growth oriented semiconductor policy and with a well maintained eco-system set up by the central government so that international player may attract to set up the wafer fabrication and R&D units in India. Keywords: FAB, ESDM, NPE, EDA, Wafer.

Structural and Morphological Studies of Nano Composite Polymer Gel Electroly...vivatechijri
n today’s society, we stand before a change in energy scarcity. As our civilization grows, many
countries in thedeveloping world seek to have the standard of living that has been exclusive to a few nations, so
their arises a need in thedevelopment of technology that is compatible enough with the resources provided by
nature in order to have sustainabledevelopment to all class of the society. In order to overcomethe prevailing
challenges of huge energy crises in near future, there is an urgent need for the development of electrical
vehiclesor hybrid electrical vehicles with low CO2 emissions using renewable energy sources. In view of the
above, electrochemicalcapacitors can fulfil the requirements to some extent.Preparation of nano composite
polymer gel electrolyte is the best optional product to overcome these problems. When fillers are added or
dispersed to the polymer gel electrolyte, amorphous or porous nature of electrolyte increases which enhances
the liquid absorbing quality of polymer and helps in removing the drawbacks of polymer gel electrolytes such as
leakage, poor mechanical and thermal stability etc. In this work dispersion of SiO2 nano filler is done in the
[PVdF (HFP)-PC-Mg (ClO4)2] for the synthesis of nano composite PGE [PVdF (HFP)-PC-MgClO4- SiO2].

An Alternative to Hard Drives in the Coming Future:DNA-BASED DATA STORAGEvivatechijri
Demand for data storage is growing exponentially, but the capacity of existing storage media is not keeping up, there emerges a requirement for a storage medium with high capacity, high storage density, and possibility to face up to extreme environmental conditions. According to a research in 2018, every minute Google conducted 3.88 million searches, other people posted 49,000 photos on Instagram, sent 159,362,760 e-mails, tweeted 473,000 times and watched 4.33 million videos on YouTube. In 2020 it estimated a creation of 1.7 megabytes of knowledge per second per person globally, which translates to about 418 zettabytes during a single year. The magnetic or optical data-storage systems that currently hold this volume of 0s and 1s typically cannot last for quite a century. Running data centres takes vast amounts of energy. In short, we are close to have a substantial data-storage problem which will only become more severe over time. Deoxyribonucleic acid (DNA) are often potentially used for these purposes because it isn't much different from the traditional method utilized in a computer. DNA’s information density is notable, 215 petabytes or 215 million gigabytes of data can be stored in just one gram of DNA. First we can encode all data at a molecular level and then store it in a medium that will last for a while and not become out-dated just like floppy disks. Due to the improved techniques for reading and writing DNA, a rapid increase is observed in the amount of possible data storage in DNA.

Cross Platform Development Using Fluttervivatechijri
Today the development of cross-platform mobile application has under the state of compromise. The developers are not willing to choose an alternative of either building the similar app many times for many operating systems or to accept a lowest common denominator and optimal solution that will going to trade the native speed, accuracy for portability. The Flutter is an open-source SDK for creating high-performance, high fidelity mobile apps for the development of iOS and Android. Few significant features of flutter are - Just-in-time compilation (JIT), Ahead- of-time compilation (AOT compilation) into a native (system-dependent) machine code so that the resulting binary file can execute natively. The Flutter’s hot reload functionality helps us to understand quickly and easily experiment, build UIs, add features, and fix bugs. Hot reload works by injecting updated source code files into the running Dart Virtual Machine (VM). With the help of Flutter, we believe that we would be having a solution that gives us the best of both worlds: hardware accelerated graphics and UI, powered by native ARM code, targeting both popular mobile operating systems.

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.

I. INTRODUCTION
Micromachining is the process of machining very small parts with tools smaller than 0.015 inch in diameter and
tolerances of just a few tenths. Micromachining can create very small and intricate parts that are required for
certain applications, particularly in the semiconductor and medical industry. It takes machinery with both
sufficient spindle speed and durable cutting tools to produce the repeatability and strength to run at high speeds.
Micromachining tools may be as small as 0.001 inch in diameter (1/3 diameter of human hair) to achieve the
precision and detail needed.In the industrial world the interest in microscopic scale manufacturing is
exponentially increasing in relation to the rapid growth of Micro Electro Mechanical Systems (MEMS) research.
Thus a greater attention is given to improve traditional techniques and developing nonconventional methods, in
order to obtain more precision.
Micromachining developed as a technique in the late 1990s, in response to an increasing demand for smaller and
more intricate parts from the semiconductor and medical industries. In response to this, precision engineers
began developing techniques to machine smaller parts with smaller tools, largely by trial and error.Finding the
right machinery and tools to deliver results on such a small scale was particularly a problem. Laser cutting
couldn’t create the clean edges required, and low RPM machines using small cutters could only provide limited
results.Upgrading to higher speed spindles and machines that are capable of producing smaller parts was
essential, and nowadays precision engineers not only use higher RPM machines to apply their own micro
milling capabilities, they also use Swiss-type lathes with live tooling and high-speed air spindles. Swiss-type
lathes can be used to create prototypes and produce small batches of turned parts that still require some milling,
