A comparative study of modern transient pipe-line techniques using ammonia as fluid medium
(1970)This thesis presents a comparative study of transient pipeline techniques using ammonia as a fluid medium. Physical properties and characteristics of the use of liquid ammonia in pipelines is first given, and then two basic ... -
A developmental study of a low cost housing system
(1969)In this thesis, a low cost housing system was developed that will sell for under seven thousand dollars per dwelling. The housing system consists of factory produced and finished modular volume units that are combined at ... -
A digital computer simulation of an automatically controlled complete mix activated sludge wastewater treatment plant using food : mass ratio control
(1975)With the activated sludge wastewater treatment process being as complicated as it is, a concerted effort is needed to develop an automatic control system which will respond effectively to variations in influent flow and ... -
A dynamic design procedure for fixed bed activated carbon adsorption of organics from concentrated industrial wastewater streams
(1970)Future fresh water supply demands require a technological fix in fresh water supply practices if such are to be met. Two courses of research appear able to provide a broader fresh water supply base: desalinization of brine ... -
A dynamic mode of the effects of groundwater recharge in the Clear Lake City-NASA area
(1976)High rates of groundwater withdrawal have resulted in serious declines in water levels in the aquifers of the Houston area. These declines have been instrumental in the high subsidence rates present in the area. The study ... -
A laboratory data acquisition system utilizing the SDS-920 computer
(1970)The problem of measuring and recording static and dynamic transducer data has long been one of vital concern to experimental stress analysts. As most of the parameters that are measured vary with time, a requirement for ... -
A laboratory scale approach to domestic solid wastes evaluation: monitoring of leachate
(1970)The landfill is the oldest and still the most commonly used type of solid waste management. In spite of this, there have been few attempts to determine the extent of the threat posed to the purity of groundwater by landfilling ... -
A method for improving performance of cooling ponds
(1970)This thesis presents the results of a study of the efficiency of a cooling pond as related to temperature decreases, residence times and flow patterns. A literature review of cooling pond design principles and operational ... -
A real time study of pollutant gaseous exhaust stack emissions from a stationary gas turbine
(1970)This thesis presents the results of a study of pollutant stack emissions from a gas turbine performed on a real time basis. Field studies were made at the site of a stationary industrial gas turbine utilizing natural gas ... -
A review and evaluation of the theoretical determination of bearing capacity and settlement of footings
(1973)The most accepted theories on bearing capacity of foundations are summarized. Factors influencing bearing capacity, such as varying ground water level, sloping ground surface, and eccentric and inclined loading, are reviewed. ... -
A review of moment distribution and its use in solving multi-story frames
(1975)This thesis presents the history of the development of the moment distribution procedure and its impact on the solution of statically indeterminate beams and frames. The basic procedure, and both approximate and exact ... -
A Scalable Variational Inequality-Based Formulation That Preserves Maximum Principles for Darcy Flow with Pressure-Dependent Viscosity
(2017-08)The overarching goal of this thesis is to present a robust and scalable finite element computational framework based on Variational inequalities (VI) which models nonlinear flow through heterogeneous and anisotropic porous ... -
A statistical evaluation of dynamic pile driving formulae in sand
(1970)Seven dynamic pile-driving formulae are used in this investigation to predict the capacity of 140 timber, precast concrete, and steel piles driven in, or to, sand. The piles were subdivided into different groups according ... -
A study of a horizontal flow vertical fixed phase biochemical wastewater treatment reactor
(1968)A bench-scale horizontal-flow, vertical fixed-phase aerobic biological process was studied with reference to support media, biological growth and film characteristics, oxygen requirements, and organic carbon removal for ... -
A study of an electrochemical process for the removal of phosphate, fluoride and ammonia from an industrial waste water
(1971)Unfortunately, not until recently has any appreciable emphasis been placed on restricting inorganic contaminants from our fresh waters and estuaries. Since a large percentage of these inorganic contaminants, mainly phosphorus, ... -
A study of creep in concrete
(1967)This volume presents a literature search on the subject of creep in concrete. Various theories are presented and discussed in detail. The factors which affect creep are critically reviewed. Results are presented on an ... -
A study of the autofrettage process
(1967)Over the past few decades, modern industrial processes have required higher and higher operating fluid pressures, and use of these high pressures have necessitated development of the auto-frettage procedure. This procedure ... -
A study of the biodegradation of organic pollutants in a dilute aqueous system
(1969)The biochemical oxygen demand test (BOD) and the chemical oxygen demand test (COD) have often been designated as tests to monitor bio degradation of organic pollutants in dilute aqueous systems. Specific limitations to ... -
A study of the buckling of built-up columns
(1968)Many steel bridges, buildings, transmission and reception towers are constructed using built-up members. The buckling load of a built-up column is of interest to the designer because bending moments and stresses from the ... -
A study of the coagulation-filtration process for the removal of suspended matter from an aqueous system
(1970)This thesis presents the results of a study of removal of particulate matter from a fresh water system by a coagulation-filtration process. Laboratory studies were made on an aqueous system containing a suspension of ...
