Score Improvement Comparison from PSAT to SAT Between two Schools
<p>The score a student earns on the PSAT is a predictor for what they earn on the SAT. Based on a student's PSAT score, we construct a Bayesian model to predict, with 95% certainty, what they will earn on their SAT. Furthermore, we explore differences in this prediction between two high schools in …

Hydrodynamic Behavior of Pop-Up Satellite Archival Tags (PSAT) Subject to Vortices
Pop-up Satellite Archival Tags (PSATs) are a combination of satellite and archival tags used by marine biologists to collect large scale movement and behavioral data of large pelagic life for up to two years [1]. However, current commercial PSATs have an unusually high failure rate when tagged on …

Comparison of DigSILENT, Matlab PST and PSAT for steady state and stability studies on HVAC-HVDC systems
It is said that the electric power system is the most complex system ever built by mankind. Over the past few decades, many software packages focusing on the study of this complex system have been developed. These software packages range from academic/ research based to industrial/commercial based …
