Small screen devices, also known as small-form-factor (SFF) devices including mobile phones and ultra mobile PCs are increasingly ubiquitous. Their uses includes gaming, navigation and interactive visualisation. SFF devices are, however, inherently limited by their physical characteristics for perception as well as limited processing and battery power. High-fidelity graphic systems have signifi...

Changes in speaking fundamental frequency (SFF) associated with aging were studied in a total of 374 healthy normal speakers (187 males and 187 females) from adolescent to older age groups. Participants were asked to read a sample passage aloud, and acoustic analysis was performed. The main results were as follows: (1) Males exhibited no significant trend for SFF changes in aging. However, a sl...

self-incompatibility is one of the main problems in almond production. in this research work, at the first step, some local cultivars as well as some imported ones were evaluated from the point of their male and female organ compatibility. then, ten selected commercial self-incompatible cultivars(female parents) were crossed with two self-compatible cultivars(male parents) i. e. tuono and super...

Rapid prototypings using direct selective laser sintering (SLS) ofmetal/ceramic powders have a great potential for design and fabrication of near net shape of metal/ceramic parts. At presents CO2, Nd:YAG and Excimer are the only possible solutions for the heavy duty manufacturing applications. At the University of Connecticut, researchers advanced the concept of rapid prototyping and other desk...

Multi-speaker separation is necessary to increase intelligibility of speech signals or to improve accuracy of speech recognition systems. Ideal binary mask (IBM) has set a gold standard for speech separation by suppressing the undesired speakers and also by increasing intelligibility of the desired speech. In this work, single frequency filtering (SFF) analysis is used to estimate the mask clos...

PURPOSE The purpose of this study was to examine the speaking fundamental frequency (SFF) and pitch sigma (individual SFF variability) of African American and Caucasian children ages 6 through 8 years. METHOD Participants in this study included 63 Caucasian and African American children recruited from 6 urban schools and 1 day care center. All participants passed hearing and speech-language s...

A simple instrument was shown to be suitable for clinical measurement of fundamental voice frequency. Basal frequency (SFF) and lowest frequency (LF) were determined in 374 normal subjects aged 6 years to adulthood. SFF fell between ages 8 and 10 years in boys (from 259 to 247 Hz), but not in girls (253 Hz). LF fell between ages 6 and 10 years in boys (from 234 to 203 Hz) and girls (from 230 to...

self-incompatibility in almond and prunus species is an important genetic trait that prevents self-fertilization. self-incompatibility in almond is controlled gametophytically by the multiallelic s-locus. this study was done in order to identification and preliminary selection of self-compatible progenies resulted from controlled crosses in almond using specific primer sff-sfr.some important mo...

Precise glycan structures on specific glycoproteins impart functionalities essential for neural development. However, mechanisms controlling embryonic neural-specific glycosylation are unknown. A genetic screen for relevant mutations in Drosophila generated the sugar-free frosting (sff) mutant that reveals a new function for protein kinases in regulating substrate flux through specific Golgi pr...

Solid Freeform Fabrication (SFF) of food has the potential to drastically impact both culinary professionals and laypeople; the technology will fundamentally change the ways we produce and experience food. Several imposing barriers to food-SFF have been overcome by recent opensource printing projects. Now, materials issues present the greatest challenge. While the culinary field of molecular ga...
