Performance_Evaluation_of_Fully_Depleted_Silicon_on_Insulator_MOSFET.pdf
VLSI technology development nowadays is mostly focused on the downsizing of semiconductor devices, which is significantly reliant on advancements in complementary metal-oxide-semiconductor technology. Due to capacitance, shorter channel length, body biassing, faster-switching transistor, limited variability, and faster running transistor, Silicon-on-Insulator technology has seen a lot of changes. In comparison to traditional bulk technology, Silicon on Insulator offers intriguing new possibilities. The recent stalling of advancement in CMOS technology has been noticed. A fully depleted silicon on the insulator provides additional performance. Power usage and communication speed are two areas where performance can be improved. Silicon on insulator technology has the potential to reduce power consumption by nearly half while increasing speed by about 40%. Using the Atlas module of the SILVACO software, the research presents a comprehensive analysis of silicon on insulator-based nano metal oxide semiconductor field-effect transistors. Atlas is used to virtually construct a 20 nm silicon on insulator MOSFET. The gate metals employed are Aluminum, N. poly, W (Tungsten), and WSi2 (Tungsten Silicide), and their respective characteristics are obtained and compared. Finally, WSi2 was chosen as the final gate metal because it has the desired band offset, resulting in a positive threshold voltage without the need for any further implants in the channel region. Other metrics are collected, such as the variation of ID vs. VGS features at various values. There is also a fluctuation in drain current as a function of drain to source voltage.

Determination of Critical Flaw Size in Gun Launched 40mm Grenade
The inspection and screening of flaws in high explosive filled gun fired projectiles are crucial to ensure safety for soldiers using these items. In bore failure of structural components are sure to produce lethal consequences, therefore it is of great importance to determine what the maximum permissible crack size is for a given component coming off of the production floor.

Secondly, the explicit model results are passed to NASGRO software for critical flaw size determination using linear-elastic fracture mechanics theory. The modeling information and approach to the problem will be presented in this paper as well as explicit model results and proposed inspection criteria.

Finite element analysis of center pin and bracket of jig fixture assembly ijm...Dr.Vikas Deulgaonkar
The manufacturing industry caters the range of products to satisfy the ever changing market needs.
To overcome the increasing production demands, the industry implies various techniques. We need a technique for
increasing the production of drilling two holes on a Railway Pinion, improve the quality of product and reduce the
operation time. This project aims to design the Jig and Fixture for the same. The 3-dimensional Computer Aided Model
of the components is made using CATIA V5-R21 software. To study the behavior of component, simulation is carried out.
Preprocessing of the CAD model is carried in Hypermesh software. Boundary conditions are applied using physical
situations of the components. Finite element analysis of the components is done, and the results obtained are compared
with the theoretical analysis and also with the available literature. The stresses and deformations are found within desired limits. Using FE analysis, the parts are manufactured and assembled. Similar to Jj204 assignment (20)

Understanding User Needs and Satisfying Them
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs
