A Study Of The Use Of Simd Instructions For Two Image Processing Algorithms, Eric Welch Dec 2012

A Study Of The Use Of Simd Instructions For Two Image Processing Algorithms, Eric Welch

Theses

Many media processing algorithms suffer from long execution times, which are most often not acceptable from an end user point of view. Recently, this problem has been exacerbated because media has higher resolution. One possible solution is through the use of Single Instruction Multiple Data (SIMD) architectures, such as ARM's NEON. These architectures take advantage of the parallelism in media processing algorithms by operating on multiple pieces of data with just one instruction. SIMD instructions can significantly decrease the execution time of the algorithm, but require more time to implement. This thesis studies the use of SIMD instructions on a …

Quantification Of Mixing In Microchannels, Vijaymaran Manickam

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microchannels are used for delivery of two-or more fluids for multiple purposes, such as drug delivery, where good mixing is desired in a very short time (or distance). For this purpose, many design options are being proposed in the literature. For example herringbone baffles at the bottom of a rectangular channel are commonly proposed to enhance mixing in a drug delivery device. To assess the effectiveness of such devices many experiments need to be performed thus increasing the design cycle time and the cost involved. Computational fluid dynamics (CFD) can and is being used to shorten this design cycle by …

The Role Of Bip Nucleotide Exchange Factor Sil1 In Immunoglobulin Biosynthesis, Tyler Sanford Dec 2012

The Role Of Bip Nucleotide Exchange Factor Sil1 In Immunoglobulin Biosynthesis, Tyler Sanford

Theses and Dissertations (ETD)

BiP is an essential endoplasmic reticulum resident molecular chaperone of the HSP70 family that binds exposed hydrophobic regions of unfolded proteins. Substrates bound by BiP are protected from dangerous non-specific interaction with other unfolded proteins via their aggregation prone exposed hydrophobic regions, which are normally buried in the native state, and act as BiP binding targets. For these substrates to mature into the native state, BiP must be released. Like all HSP70 family members, cycles of BiP binding and release are nucleotide dependent and facilitated by two genres of cochaperones, HSP40s, and nucleotide exchange factors (NEFs). HSP40s function in stimulating …
