A deterministic model was developed to predict pollutant mass first flush and to utilize it for better design of best management practices (BMPs) that focus on treating the first flush. The model used the kinematic wave equation to calculate flow and mass transport, and erosion equations to calculate pollutant concentrations, which were assumed to be from a short and a long term source. The mod...

II. BACKGROUND Abstract: This paper describes the application of distributed system techniques to an MIT Media Lab sponsored project on multi-point video recording. The two main improvements to the system are: (1) An algorithm to calculate optimum camera angle based on the locations of other cameras in the system and (2) A method of forwarding information between out-ofrange cameras via interme...

introduction: radioactive materials deliver internal radiation dose to patients in nuclear medicine. manual internal radiation dose assessment is a complicated method. introduction of a simple dose calculation software is the main goal of the present study. methods: using the best current data in internal dose calculation (s-factors) recommended by icrp and by considering other technical metho...

The aim of the present study is to determine the feasibility of making a rectangular twist waveguide used to rotate electromagnetic waves. For this purpose, the process of fabricating an aluminum rectangular twist waveguide was simulated by making use of finite element method and Deform software. The optimum length and angle of the twist die for manufacturing a twist waveguide with inner cross ...

1. The mesothoracic wings of tettigoniid insects are used in song production and flight; the metathoracic wings in flight only. In Neoconocephalus triops the wing stroke frequency during flight is about 25 Hz; the frequency during singing about 100 Hz. 2. The twitch duration of mesothoracic, first tergocoxal (Tcxl) wing muscles is only about one-half the duration of the upstroke or downstroke p...
