Index Testing With a Data Acquisition and Control System
A computer controlled index test has been developed that can be used to optimize blade-gate relationships on adjustable blade (Kaplan) hydraulic turbines. This paper includes hardware...

Basic Considerations in Governed or Non-Governed Small Hydro Power Plants
This paper reviews the necessary studies and major considerations that must be completed for proper coordination and selection of a turbine governor, and generator. A discussion of the...

Grand Coulee SCADA System Procurement
Purchasing a quality Supervisory Control and Data Acquisition (SCADA) or Energy Control System (ECS) at a reasonable price for a particular installation can be a challenging undertaking....

Kaplan Blade Angle Controller
This paper describes a recently developed computerized Kaplan blade angle controller that is capable of improving turbine performance. Model Tests or Index Tests produce the Three-D-Cam...

Capabilities of Automated Control System Employing Advanced Programmable Controllers
This paper details Voith Hydro's range of experience in the use of Programmable Logic Controllers (P. L. C. 's) in the automation of new hydro electric sites....

Integrated Automatic Hydroelectric Plant Control
The increased acceptance and employment of microcomputers to control specific functions in small hydroelectric plants has led to computerized integrated total control of hydropower generation....

Accelerated Life Testing of Generator Coils
This paper presents a step-by-step procedure for doing a 400 hour, 60 Hz, 90 degree C accelerated life test on generator coils. Test procedure is as follows: 1. Initial coil examination...

Geotechnical Exploration and Site Preparation Techniques for Large Mall in Karst Terrain
A large commercial mall and secondary developments were planned for construction in a karst area near Clarksville, Tennessee. A geotechnical exploration was conducted to evaluate the occurence...

Geosynthetics for Soil Improvement: A General Report and Keynote Address
The paper summarizes major developments in the field of geosynthetics since the previous symposium in 1980. The paper addresses the engineering functions of major types of geosynthetics,...

Subsidence Over AML and Its Causes?A Case Study
Subsidence over abandoned mined lands can be attributed to several causes. For purposes of compensation and liability and developing remedial measures, it is essential to identify the...

Recent Thoughts on Probabilistic Fatigue Crack Growth
We briefly review recent results of analysis of fatigue crack growth data. Implications of this analysis are presented, and reasons are advanced in favor of increasing the dimension of...

Statistics of Concrete Shrinkage Test Data
The paper reports a large series of concrete shrinkage tests which can be used for statistical purposes. The series involves two groups of 36 identical cylindrical specimens, with a diameter...

Reliability of Geotechnical Systems Considering Geological Anomaly
Anomaly statistics at a given site are first assessed through Bayesian methodology on the basis of site exploration data. Several methods may be then used to incorporate the anomaly uncertainties...

Statistical Analysis of Occupant Dynamic Loads
Human-induced load-time histories were modeled by several dependent descriptive parameters. These parameters were treated as functions of two independent variables in a multivariate regression...

Design Wind Loads for Broadcasting Antennas from Short Time Records
Very useful would be procedures for the determination of the design wind load on the basis of short time records, of duration comparable with the preliminary and/or design phases, so that...

Approximate Reasoning in Engineering Decision Analysis
In this paper, the concept and methods of approximate reasoning are reviewed and discussed. The methodology of combining precise results of exact analysis, approximate solutions of exact...

Using the Microcomputer in the Software Development Process
The migration of the computer from the controlled environment of a computer room to the office desk-top provides the software engineer with a convenient and effective tool for enhancing...

Computerized Bridge Coding for HEC-2 Applications on I.B.M. P.C.
A computer program for conversion of survey field notes directly into SB, BT, and GR cards with simultaneous cross-section plot is described. It was designed to simplify the coding of...

Introducing Geostatistics?Estimating Spatial Data
The theory of regionalized variables commonly known as geostatistics is now being applied throughout the community of engineering and sciences. Measurements taken at different locations,...

Getting the VOCs Out of Well Water
Two technologies are successfully removing volatile organic chemicals (VOCs) from groundwater supplies. Not surprisingly, since the application is new, many of the designs were not optimized...
