Abstract Aeration is the process of increasing dissolved oxygen (DO) content water, which an important water quality parameter for survival aquatic life. In this process, large amounts air bubbles develop; as a result, contact surface area increases, and hence water-air-mass transfer accelerates. There are numerous methods DO concentration in including self-aeration, mechanical aeration, chemic...

Both timbre and dynamics of isolated piano tones are determined exclusively by the speed with which the hammer hits the strings. This physical view has been challenged by pianists who emphasize the importance of the way the keyboard is touched. This article presents empirical evidence from two perception experiments showing that touch-dependent sound components make sounds with identical hammer...

Large-Scale Particle Image Velocimetry (LSPIV) is an extension of a quantitative imaging technique to measure water surface velocities using simple and inexpensive equipment. This paper describes the implementation of imaged-based LSPIV in eight different environmental flow and hydraulic engineering applications for the investigation of complex configurations with and without sediment transport...

INTRODUCTION The objective of this study is to provide a synthesis of the pertinent design criteria for submerged bendway weirs. The technical paper is an extension of previous research conducted by the National Center for Computational Hydroscience and Engineering (NCCHE) at the University of Mississippi on the hydrodynamic effects on flow characteristics and effectiveness of submerged bendway...

Common coding theory suggests that any action (pressing a piano key) is intimately linked with its resultant sensory effect (an auditory musical tone). We conducted two experiments to explore the effect of varying auditory action-effect patterns during complex action learning. In Experiment 1, participants were assigned to 1 of 4 groups, watched a silent video of a hand playing a sequence on a ...

This paper reviews the work of Keshava Munhy and collaborators in the area of proportional weirs. It brings forlh the lacuna that existed in the theory of weirs and focusses on why there was need a for a generalized theory of ,,"'(irs. It oullines the theorem of slope discharge continuity developed, emphasizing the importance of a datum or reference plane for every weir. It explains briefly the...
