Conduction Theories in Gaseous Plasmas and Solids: Final Report, 1961
The theoretical studies on the transport proper ties of ionized media performed have been based entirely on the effective particle approach and have ignored all correlation effects as well as quantum corrections. Within this approximation several specific problems have been treated: the anomalous skin effect, the magneto-acoustic effect, magneto-galvanic resistance, and certain aspects of microwave diagnostics. The first two effects are of considerable interest in metals and semi-metals and were studied and extended so as to apply to plasmas. The microwave diagnostic techniques developed here were originally aimed at the interpretation of a specific problem in plasma physics but are of sufficient generality to treat a class of problems involving magneto hydrodynamic fluids, semi-metals, as well as semi-conductors
State Case Studies of Infant and Early Childhood Mental Health Systems: Strategies for Change
Profiles efforts to develop mental health identification and intervention systems for children up to age 5 in Colorado, Indiana, Massachusetts, and Rhode Island. Examines hurdles, reform potentials, and lessons learned, including the role of partnerships
Noise reduction in time series data from dynamical systems.
Introduction: The objective of this thesis is to determine if the amount of noise in the observed time series data has affected the outcome of the chaotic descriptors. To thoroughly analyzed this problem I will first introduce how the data was obtained, next how to find the chaotic descriptors, and then discuss and apply noise reduction techniques
Composition of sea water
The principle of constant ratios between the salts in ocean water unaffected by land drainage was laid down by Forchhammer in 1864, and firmly established by Dittmar (1884) . Dittmar\u27s examination of 77 samples, collected from all the oceans of the world by H .M.S. Challenger in 1873-76, was so comprehensive, and his results so consistent, that some of his values are used to this day
Simplex Algorithm for Optimizing Drainage Design
A methodology and computer model is developed to determine economically optimum closed subsurface drainage systems in irrigated areas. The model maximizes net benefits, by comparing profit driven by crop yield to drain system cost and selects an optimum drain layout. The optimization methodology used, is the SIMPLEX method, Neider and Mead. The SIMPLEX model was linked to the subsurface drainage model DRAINMOD Skaggs [10], and to the surface hydraulic model KINE, Walker and Skogerboe[14]. The selected optimum drainage system maximizes the difference between total revenue, and the total cost of installation, operation and management of a particular drainage system. The optimization sub-program provides a workable and simple procedure for optimizing water management simulation models
