Effects of Promoting Health Among Teens: A Brief General Health Program Intervention For African American Adolescents From A Multi-Site Trial
… such program is Promoting Health Among Teens (PHAT) - a brief, culturally tailored intervention to increase general health knowledge and improve health behavior for African American adolescents. The effects of this program were evaluated among 1654 African American adolescents in the eastern …

Time Delay Estimate Based Direction of Arrival Estimation for Speech in Reverberant Environments
… steered response power with phase transform (SRP-PHAT), are available that perform better than TDE based algorithms, the huge computational load required for this algorithm makes it unsuitable for applications that require fast refresh rates using short frames. In addition, the estimation errors …

A binaural sound sources localisation application for smart phones
… scenes with help of human users. The GCC-PHAT algorithm was chosen as the underlying core DOA algorithm due to its suitability for pair-wise localization as highlighted in literature. A stochastic power accumulation algorithm was designed and implemented to improve estimation outcomes by …

Domain-specific accelerators using optically-addressed phase change memory
… To tackle these challenges, we propose PHAT, a Photonic Accelerator for TFHE that leverages OPCM. OPCM-based PIM systems offer high computational and communication throughput, making them well-suited for accelerating FFT operations in TFHE. Nonetheless, mapping FFT computations onto OPCM …

Development of Robust Correlation Algorithms for Image Velocimetry using Advanced Filtering
… incorporate the use of the Phase Transform (PHAT) Generalized Cross Correlation (GCC) filter applied to the image cross-correlation. The use of spatial windowing is subsequently examined and shown to be ideally suited for the use of phase correlation estimators, due to their invariance to the …

The Andromeda Optical and Infrared Disk Survey
… from the Panchromatic Hubble Andromeda Treasury (PHAT) survey (Williams et al. 2017). We find substantial (0.3 dex) differences in stellar mass estimates despite a common use of the Chabrier (2003) initial mass function. Stellar mass estimated from the resolved stellar population is larger than …
