The document discusses abrasive processes for material removal. Grinding is the most important abrasive process where abrasive particles in a rotating wheel remove material from a workpiece. Other abrasive processes include honing, lapping, and superfinishing which use bonded abrasive sticks or abrasive particles in a fluid to create very fine surface finishes on complex geometries. Grinding can be done on surfaces or cylinders and is often used as a finishing process to achieve close tolerances and surface finishes not possible with other machining operations.Tangent cam

A tangent cam has straight flanks that are tangential to the base circle and nose circle. It is known as a tangent cam. A tangent cam is used when a roller has contact with the straight flank. One application of a tangent cam is in operating valves in internal combustion engines. There are two cases of a tangent cam: when the roller has contact with the straight flank and when the roller has contact with the nose.Optical measurent Mitesh kumar

Friction is a force that opposes the relative motion between two objects in contact. There are two main types of friction: static friction and dynamic friction. Static friction acts on objects at rest, while dynamic friction acts when objects are in motion. Dynamic friction is less than static friction. Friction can also be classified as sliding friction, rolling friction, or pivot friction depending on the type of relative motion. The coefficient of friction is defined as the ratio between the limiting friction force and the normal reaction force. The limiting angle of friction is the maximum angle at which an object will remain at rest on an inclined plane before sliding down. The angle of repose is the angle of inclination at which an object will just begin to slideKOM-Unit V-clutches

Womens security is a critical issue in todays world and its very much needed for every individual
to be acting over such an issue. This document describes a GPS based Women Security System''
that provides the combination of GPS devices as well as provide alerts and messages with an
emergency button trigger whenever somebody is in trouble They might not have so much time, all
that they have to do is generate a distress emergency signal by shaking up their phone. Our system
provides a realizable, cost effective solution to problem detection. Nowdays due to recently
happened cases such as rape by drivers or colleagues, burglary etc., women security, especially
women security has become the foremost priority of the world. System uses the Global Positioning
System (GPS) technology to find out the location of women. The information of women's position
provided by the device can be viewed on Google maps using Internet or specialized software. The
companies are looking for-ward to the security problem and require a system that will efficiently
evaluate the problem of women security working in night shifts, traveling alone. We focus on the
proposed model that can be used to deal with the security issue of women using GPS based tracking
systems.How to Un-Obsolete Your Legacy Keypad Design

For any number of circumstances, obsolescence risk is ever present in the electronics industry. This is especially true for human-to-machine interface hardware, such as keypads, touchscreens, front panels, bezels, etc. This industry is known for its high mix and low-volume builds, critical design requirements, and high costs to requalify hardware. Because of these reasons, many programs will face end-of-life challenges both at the component level as well as at the supplier level.
Redesigns and qualifications can take months or even years, so proactively managing this risk is the best way to deter this. If an LED is obsolete or a switch vendor has gone out of business, there are options to proceed.
In this webinar, we cover options to redesign and reverse engineer legacy keypad and touchscreen designs.

Kotlin can be very handy and easy to use. Kotlin offers the possibility to develop code that is easy to understand, safe, immutable, and thus predictable and follows standards that avoid side effects. I realized that very quickly after I started my Kotlin journey that already amounts to more than 5 years.
This is the third version of this presentation focused on more detail explaining inline, crossinline, tailrec and as a bonus a quick run through unnamed classes.Tally.ERP 9 at a Glance.book - Tally Solutions .pdf

Step into the world of high-performance programming with the Complete Guidance Book of C++ Programminga definitive resource for mastering one of the most powerful and versatile languages in computer science.
Whether you're a beginner looking to learn the fundamentals or an intermediate developer aiming to sharpen your skills, this book walks you through C++ from the ground up. You'll start with basics like variables, control structures, and functions, then progress to object-oriented programming (OOP), memory management, file handling, templates, and the Standard Template Library (STL).Modern multi-proposer consensus implementations
Modern multi-proposer consensus implementationsFran巽ois Garillot

Multi-proposer consensus protocols let multiple validators propose blocks in parallel, breaking the single-leader throughput bottleneck of classic designs. Yet the modern multi-proposer consensus implementation has grown a lot since HotStuff. THisworkshop will explore the implementation details of recent advances DAG-based approaches like Narwhal and Suis Mysticeti and reveal how implementation details translate to real-world performance gains. We focus on the nitty-gritty: how network communication patterns and data handling affect throughput and latency. New techniques such as Turbine-like block propagation (inspired by Solanas erasure-coded broadcast) and lazy push gossip broadcasting dramatically cut communication overhead. These optimizations arent just theoretical they enable modern blockchains to process over 100,000 transactions per second with finality in mere milliseconds redefining what is possible in decentralized systems.
