Face recognition is challenging especially when the images from different persons are similar to each other due to variations in illumination, expression, and occlusion. If we have sufficient training images of each person which can span the facial variations of that person under testing conditions, sparse representation based classification (SRC) achieves very promising results. However, in ma...

Entire matrix-valued functions of a complex argument (entire matrix pencils) are considered. Bounds for spectral variations of pencils are derived. In particular, approximations of entire pencils by polynomial pencils are investigated. Our results are new even for polynomial pencils. © 2005 Elsevier Inc. All rights reserved.

Matrix balancing is a term that describes the process of altering the elements of a matrix to make it conform to known regularity conditions while still remaining close to the original matrix Often the regularity conditions relate only to the row and col umn sums which yields problems having a desirable network structure We describe an application in telecommunication demand forecasting that ad...

Due to the mismatch of mechanical properties in composite laminates, propagation of delami-nation is considered as a severe damage mechanism in beams with various lay-up configurations. Delamination can be generated due to matrix cracking propagation or it can also be initiated due to the manufacturing process before using composite beams. Using a micromechanics model, this study is aimed to in...

Material layers with a thickness of a few nanometers are common-place in today’s semiconductor devices. Before long, device fabrication methods will reach a point at which the other two device dimensions are scaled down to few tens of nanometers. The total atom count in such deca-nano devices is reduced to a few million. Only a small finite number of “free” electrons will operate such nano-scal...

Business operations are always under the influence of variations due to change in customer needs, market demands, internal processes and technology upgrades. These changes have direct impact on the performance of IT processes cascading down to the quality of products/services. In order to mitigate the adverse effects due to the variations of the aforementioned, organizations need to understand ...
