Two source signals are provided to the system: a sine wave, A, and the sine wave, B, phaseshifted by ninety degrees compared to A. These are the supply signals, in phase and quadrature. The signal analyzer is used to measure the difference in phase between the input and outputsignal across the test component.II.

Roughness Front Figure 3- Inspection Probe (b)The inspection probe consists of a visible laser light source surrounded by four photo detectors.The idea of the apparatus is that laser light is transmitted along a hollow tube and reflects 90° offof a mirror and onto the surface of interest. If the surface is a mirror finish with no roughness,the light would be reflected back along the same path directly towards the laser source. If thesurface contains a rough finish the laser light will still reflect most of its light back towards thesource, but a portion of it will become scattered. Some of the scattered light will find its wayback down the tube, but not collinear with

After the material cools and the field is removed, theWeiss domains roughly remain in alignment. As a result, the material now has its own polaritywhich can be degraded by exceeding the mechanical, thermal, and electrical limits of thematerial. Subsequently, there is a growth in the direction parallel to the polarization and acontraction in the direction

-assurance era.”What the Physicists Do With Entangled PhotonsThe word “entangled” implies more than just correlation (however entangled photons willexhibit correlation in their measurement statistics). Systems A (or Alice) and B (or Bob) areentangled if their state vector is not a simple product, i.e., if it cannot be written in the form:(state of A)a times (state of B)b. Now taking (+) to represent the state of “spin up” along z and(-) to represent “spin down” – the only two possible spin states of an electron, an example of anentangled state is: (+)a (-)b + (-)a(+)b. If we ask “what is the spin of A?” the answer is – well itcould be up or down, depending on if we “draw” the first or second term respectively when wemeasure it’s state. However, we

respect to the plates, a uniform shear stress occurs across the plates.The steady state inelastic response that commences at a shear stress of 40 MPa continues until Page 12.1338.2fracture at 8% strain. The main role of inelasticity is its insensitivity to localized deformationsites that causes premature failure.The robustness of nacre arises from four design principles as postulated by He et al.1. These are:a) morphology which is optimized to maximize inelastic strain, b) nanoscale asperities that causemechanical interlocking at the interface; sufficient adherence of ceramic layers by the bond layerand d) lubrication provided by the polymer1.

An example final contest is shownin Fig. 4. In this contest, students appliedpreviously learned techniques to program theirrobot to autonomously find a soda can in amaze, and carry it to a ‘recycle bin’. The bin’sposition varied, but was always found under alight in the top section of a maze. The robotwas required to pass over certain “detectionpads” (A,B,C) to turn on the recycle

Determining Process Capability of an Industrial Process in Laboratory Using Computer Aided Hardware and Software ToolsAbstractQuality means suitability for use and it is inversely proportional to variability of product, service,people, processes, and environment. However, it is the dynamic state that is associated with eachof the above and that meets or exceeds expectations of a customer. Quality improvement istherefore the progressive reduction of variability. The gradual reduction of process and productvariability can be done by successive determination and removal of the causes responsible for thevariability.For a process industry, causes of product variability happen generally

Experimentationprovides students with a sense of where things deviate from theory, offering the opportunity toexplore non-ideal conditions; while also giving them the chance to play with hardware and gain theexperience and expertise that helps them become successful designers.1,2 For example, electronicstechnicians who had vast hands-on experience were able to reproduce large portions of complexcircuit diagrams after only a few seconds of viewing; whereas novices could not.3 This was due totheir ability to chunk the individual circuit elements that functioned together as an amplifier.Expert scientists and engineers are able to quickly recognize patterns of information; for example
