Amorphous Silicon Carbide Solar Cells Fabricated Using Ecr-Pecvd, Vu Anh Vu Jan 2000

Amorphous Silicon Carbide Solar Cells Fabricated Using Ecr-Pecvd, Vu Anh Vu

Retrospective Theses and Dissertations

Solar power is becoming important as an alternative energy source. Solar power generation utilizes solar cells, which generates DC electricity when light falls on them. Attractive materials for solar energy conversion are amorphous silicon (a-Si) and its alloys, such as amorphous silicon carbide (a-(SiC)). Although research on a-Si solar cells has been carried out in many countries since the 1970's, a-(SiC) solar cells have not been widely studied. Amorphous silicon carbide has a wider bandgap than amorphous silicon; therefore, we can expect to have solar cells with larger open-circuit voltage and high conversion efficiency for the high-energy ...

Class: A Nondestructive Flaw Classification System, Loren G. Knutson Jan 1995

Class: A Nondestructive Flaw Classification System, Loren G. Knutson

Retrospective Theses and Dissertations

One important application of nondestructive evaluation (NDE) methods involves the classification of the types of defects present in materials based on the measured response of those defects to different types of interrogating energy. This classification process typically involves 1) the transformation of the "raw" NDE measurements into domains more suitable for classification purposes, 2) the extraction of features in those domains that are distinguishing characteristics of different flaw types, and 3) the application of a particular classification method for making a decision on the type of flaw present (based on the strength of the features). Here, we describe the elements ...


An Ms Windows Prototype For Automatic General Purpose Image-Based Flaw Detection, Jorn Lyseggen Jan 1994

An Ms Windows Prototype For Automatic General Purpose Image-Based Flaw Detection, Jorn Lyseggen

Retrospective Theses and Dissertations

Flaw detection plays a crucial role in many industries to make sure that the products meet the specified quality requirements. When making for example a car it is important that all the parts satisfy certain quality standards to make sure the consumer buys a car that is safe to operate. A crack or another weakness in a crucial part can be catastrophic. To make sure their cars are as safe as possible, car manufacturers are conducting thorough testing of crucial parts. Similar tests are done in a wide variety of industries, and these quality controls are often referred to as ...


Tomographic Inspection System Using X-Rays, Vivekanand R. Kini Jan 1994

Tomographic Inspection System Using X-Rays, Vivekanand R. Kini

Retrospective Theses and Dissertations

Tomography refers to the cross-sectional imaging of an object from either transmission or reflection data collected by illuminating the object from many different directions. This technique revolutionized diagnostic medicine since it enabled doctors to view the slices of internal organs of the patient using x-rays. For the same reason, the method is being used in industry for applicationa such as inspection of turbine blades, rocket motors, ceramics, electronic components, castings, etc. The mathematical basis of CT was established by J.Radon in 1917 when he showed that it is possible to determine the value of a function over a region ...
