Sewing Machine Needles by W. A. Wimalaweera Introduction We know that the needle is a main element in the sewing machine. Earlier people used tiny pieces of material for sewing. Initially they were made from hones or bones of animals. In this session we will follow the gradual improvement of the needle. According to the type of material‚ there are different types of needles available. How ever the structural parts of a needle is common to all types. Needles are available in a wide range of sizes

“All Can Be Lost: The Risk of Putting Our Knowledge in the Hands of Machines” by Nicholas Carr shows the negative effects of automation and how fast it is growing. With how fast automation is growing these days‚ it is easier to hand the most difficult jobs to machines to replace humans. In this article‚ Carr talks about some dangerous experiences that were caused by automation. Carr opens up the article with stories of where some people make a costly mistake and didn’t know how to fix it. The plane

They were originally designed to machine metals; however‚ with the advent of plastics and other materials‚ and with their inherent versatility‚ they are used in a wide range of applications‚ and a broad range of materials. In machining jargon‚ where the larger context is already understood‚ they are usually simply called lathes‚ or else referred to by more-specific subtype names (toolroom lathe‚ turret lathe‚ etc.). These rigid machine tools remove material from a rotating workpiece via

Therefore‚ for it to ensure a timely and a sufficient supply of masterbatches to its customers‚ we will be suggesting theoretically possible means to increase production capacity‚ evaluate them qualitatively‚ then try to adjust them to SPC’s case. The flowchart in figure 1 depicts a logical tree on how to increase capacity in a firm: Optimization of Machine Utilization • Reduce Equipment Loss by setting monitors that track machines’ input to make sure it

EE 2403 SPECIAL ELECTRICAL MACHINES 2 MARKS UNIT-I - SYNCHRONOUS RELUCTANCE MOTOR 1. What is synchronous reluctance motor? A reluctance motor is a type of synchronous electric motor which induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. 2. Define the characteristics of synchronous reluctance motor. The synchronous reluctance motor is not self starting without the squirrel cage. During run up it behaves as an induction

The Physics of an MRI Machine. Whitney Wright PH106/006 Dr. Probst 06/05/2012 The Physics of an MRI Machine There are many physical concepts used in a Magnetic Resonance Imaging‚ also known as MRI‚ machine. There are many physical concepts used when an MRI is taken of the body‚ such as; radio waves‚ resonance and pulse sequences‚ magnetic fields being produced and lastly‚ magnets. Radio waves much stronger than the magnetic field of the Earth are sent through

R.Yusuf Akbal 210112409 03.05.2013 Can machines be conscious? Can machines be conscious? Well‚ the answer actually depends on the kind of machines you are talking about. Based on quite a few instances and research work done on this particular topic‚ I think that the machines can indeed be categorized as conscious beings and in the following paragraphs I will be providing a couple of examples in order to support my argument. If we look at the definition of consciousness‚ which implies that ‘one

Economic Tools and Concepts The shortage of physician in the Unites States is a concern today and will likely continue to be a concern for American healthcare into the future. Some of the reasons sited for physician shortages include population growth‚ aging patients‚ and physician retirement (Dill & Salsberg‚ 2008). The economic concepts of supply and demand‚ price elasticity‚ and marginal analysis can help explain this trend and project the possible changes to physician supply in the future
