Test compression was developed to help address this problem. When an ATPG tool generates a test for a fault or a set of faults Jack Conklin Titans Jersey , only a small percentage of scan cells need to take specific values. The rest of the scan chain is do not care and are usually filled with random values. Loading and unloading these vectors is not a very efficient use of tester time. Test compression takes advantage of the small number of significant values to reduce test data and test time. The idea is to modify the design to increase the number of internal scan chains, each of shorter length. These chains are then driven by an on-chip decompressor, usually designed to allow continuous flow decompression where the internal scan chains are loaded as the data is delivered to the decompressor.One common choice is a linear finite state machine where the compressed stimuli are computed by solving linear equations corresponding to internal scan cells with specified positions in partially specified test patterns.The major difference between the two types of loading is the strain which would have opposite signs for tension (positive—it gets longer) and compression (negative—it gets shorter).When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand if the material compresses and shortens it is said to be in compression.Ceramics typically have a much higher compressive strength than tensile strength. Composite materials tend to have higher tensile strengths than compressive strengths. Industrial and consumer packages other than boxes can also be subjected to compression testing: drum, pail Jonnu Smith Titans Jersey , bottle, etc. Package components are also evaluated for compression resistance.
Tension testing is by far the most extensively developed and widely used test for material behavior, and it can be used to determine all aspects of the mechanical behavior of a material under tensile loads, including its elastic Taywan Taylor Titans Jersey , yield and plastic deformation and its fracture properties.Compression tests and torsion tests are alternative approaches that overcome this limitation. Compression-test specimens are simpler in shape, do not require threads or enlarged ends for gripping and use less material than tension-test specimens. Compression tests are often useful for subscale testing and for component testing where tension-test specimens would be difficult to produce.In highly textured materials that deform by twinning, as opposed to dislocation slip, compressive and tensile deformation characteristics differ widely. The failure of unidirectionally reinforced composite materials Adoree' Jackson Titans Jersey , particularly along the direction of reinforcement, is much different in compression than in tension.The characteristics of deformation during axial compression testing are described, including the deformation modes,compressive properties and compression-test deformation mechanics.Higher compression ratios will however make gasoline engines subject to engine knocking if lower octane-rated fuel is used Corey Davis Titans Jersey , also known as detonation. This can reduce efficiency or damage the engine if knock sensors are not present to retard the timing. Cds: Duplication Vs. Replication Cds: Duplication Vs. Replication February 7, 2014 | Author: Darrel Jefferson | Posted in Business Just when people were beginning to figure out exactly how to duplicate CD-ROMs and DVDs, the mainstream media switches to the Blu-Ray disc. This shift has come as a result of more advanced technology that allows for higher quality viewing. DVDs were read by a red laser, which was far more advanced than the no lasers involved in VHS. Blu-ray discs on the other hand are read by blue lasers Harold Landry Titans Jersey , hence the name.
First and foremost, CD duplication is something that you can do yourself in your home. With the rise of computer technology, chances are, you can even duplicate a CD right from your laptop. This is a really easy process that consists of you buying some blank CDs Rashaan Evans Titans Jersey , putting the CD into your computer, and then simply pressing the right button to have your CD in no time. At this point, you have four options to label your CD. Those options are marking it by hand, printing out a label Kevin Byard Big Tall Jersey , printing on the CD, or printing using thermal transfer.
All of these processes are handled in a mass producing factory, worked by automated machines in order to not allow for any error. Blu-Ray replication begins with master copies which must be provided on a portable hard drive, unlike DVD masters. Then a glass master Derrick Henry Big Tall Jersey , or aluminum master disc, is created from that. The glass master is then used to stamp the information and content into the hot polycarbon. This allows the Blu-Ray player to be able to read the imprints on the discs.
If you have ever seen a mix CD that your friend made, then you probably have seen a boring CD with unreadable print that nobody can understand written in a thick black sharpie. Although this might work for friends or maybe family, if you want to step up your game professionally Jack Conklin Big Tall Jersey , then you are going to also want to consider CD and DVD duplication.
Print on the CD – Some printers can print onto CD with affordable ink. This is a great option for those trying to avoid the thickness problem but still want a nice looking CD. This type of print though can wear off and this process can take some time to complete.
As Blu-Ray players can still read DVDs but DVD players cannot read Blu-Ray discs, it would be wise to make the shift now from DVD player to Blu-Ray player. Not only are DVDs going the way of the VHS, but Blu-Rays are becoming increasingly less expensive and more accessible. Soon enough DVDs will be a thing of the past and you will not be able to watch anything at home without a Blu-Ray player.
