Distributional Boundary Values Of Harmonic And Analytic Functions, R. Estrada, R. P. Kanwal Jan 1982

Distributional Boundary Values Of Harmonic And Analytic Functions, R. Estrada, R. P. Kanwal

Faculty Publications

A theory for distributional boundary values of harmonic and analytic functions is presented. In this analysis there arise several indicators that measure the growth of these functions near the boundaries. An extension of the Phragmén-Lindelöf maximum principle is derived. Furthermore, the algebraic properties of the space of real periodic distributions are studied. By introducing a new product, the harmonic product, the boundary conditions involving harmonic functions are transformed into ordinary differential equations. © 1982.

Control Algorithms, Tuning, And Adaptive Gain Tuning In Process Control., Alberto Arner Rovira Jan 1981

Control Algorithms, Tuning, And Adaptive Gain Tuning In Process Control., Alberto Arner Rovira

LSU Historical Dissertations and Theses

Controller tuning relationships based on optimizing the response of a first order lag plus dead time process are developed for proportional-plus-integral (PI) and proportional-plus-integral-plus-derivative (PID) control algorithms. Minimum error integrals were used as criteria of performance for the feedback control loop. The relationships presented are shown to provide excellent response characteristics in particular for processes where little or no overshoot is desired. The effect of applying the proportional action to the feedback variable in a PI control algorithm is analyzed and found to provide a more consistent response to set point changes and load changes than the conventional PI algorithm, …

Feasibility Analysis, Dynamics, And Control Of Distillation Columns With Vapor Recompression., Edgar Hernandez Jan 1981

Feasibility Analysis, Dynamics, And Control Of Distillation Columns With Vapor Recompression., Edgar Hernandez

LSU Historical Dissertations and Theses

The conventional distillation system owes its existence to its simplicity, low investment, and inexpensive energy. Inexpensive energy is something that belongs to the past. Therefore, vapor recompression has indeed become more attractive despite the more complex flow arrangements. In this research, a steady state model was developed to study the effect of different variables on the feasibility of heat pump installations. As expected, the heat pump system favored the close boiling mixture against the wide boiling mixture. A relationship between the savings and the thermodynamic availability of the mixture was devised. The savings were also found to be very sensitive …

The Effects Of Noise, Provocation, And Level Of Self-Awareness On Physical Aggression., John Fontan Knipmeyer Jan 1981

The Effects Of Noise, Provocation, And Level Of Self-Awareness On Physical Aggression., John Fontan Knipmeyer

LSU Historical Dissertations and Theses

The cognitive-labeling hypothesis states that the arousal properties of noise will increase aggression only if a person has been provoked and labels the arousal as anger. The arousal hypothesis states that noise-induced arousal may directly increase aggression. It is suggested that discrepant findings are due to differences in subjects' level of self-awareness when participating in sedate versus physical measures of aggression. Male subjects engaged in physical aggression by throwing balls at a confederate within a 2 x 2 x 2 design comprised of provocation versus no provocation, noise versus no noise, and low versus high self-awareness. The ball-throwing was videotaped …

Methane Production From Alkaline Food Waste., Wilson Thomas Gautreaux Jr Jan 1981

Methane Production From Alkaline Food Waste., Wilson Thomas Gautreaux Jr

LSU Historical Dissertations and Theses

Anaerobic digestion of an alkaline food waste for methane production was investigated. The waste generated by potato processing contained significant quantities of carbohydrate degradation products and sodium carbonate. Anaerobic digestion was determined to be a reliable process for waste treatment and methane production. The high sodium levels did not inhibit anaerobic digestion at a substrate concentration of 1.0 wt % alkaline peel solids. Single and two-stage (separate acid, methane stages) anaerobic digestion systems were studied. In two-stage bench-scale studies at 37(DEGREES)C, methane production averaged 0.28 m('3)/kg COD feed or 0.65 m('3)/(m('3)(.)d) in a settled bacterial sludge methane fermenter with a …

Simulation And Evaluation Of Distillation Control Systems Which Control Pressure With Reboiler Heat., William Bell Stewart Jr Jan 1981

Simulation And Evaluation Of Distillation Control Systems Which Control Pressure With Reboiler Heat., William Bell Stewart Jr

LSU Historical Dissertations and Theses

A recent industrial development in distillation control strategy is to involve pressure control as an integral part of an overall control strategy, rather than as an external feature. This approach is not to simply maintain column pressure, but to manipulate other variables using the pressure as a controlled variable. In order to study control systems which utilizes this approach, a rigorous non-linear multicomponent dynamic distillation model which includes pressure dynamics was developed. The model was based on total mole, component, and enthalpy balances as well as phase equilibrium relationships and tray hydraulics on each stage. The differential equations of this …
