Characteristic Surfaces For Three Position Function Generation With Planar Four Bar Mechanisms, Clark R. Barker, P. L. Tso Jan 1987

Characteristic Surfaces For Three Position Function Generation With Planar Four Bar Mechanisms, Clark R. Barker, P. L. Tso

Mining Engineering Faculty Research & Creative Works

This paper considers the relationship between the three-position function generation problem and the solution space for planar four bar mechanisms. The two infinities of solutions possible are mapped in a plane to determine the locations where particular types of mechanisms occur. It is possible to generate a contour in the mapping plane which joins together all solutions which possess a common characteristic in regard to their link lengths. This same contour can be displayed in the solution space to ascertain the overall characteristics of potential solutions to the design problem. A numerical example is used for illustrative purposes, but the …

Microstructural Inhomogeneity In Sintered Pb(Mg1/3nb2/3)O3‐Pbtio3 Based Dielectrics, Jyoti P. Guha, Harlan U. Anderson Jan 1987

Microstructural Inhomogeneity In Sintered Pb(Mg1/3nb2/3)O3‐Pbtio3 Based Dielectrics, Jyoti P. Guha, Harlan U. Anderson

Materials Science and Engineering Faculty Research & Creative Works

The sintering behavior and microstructural development of dielectric ceramics based on Pb(Mg1/3Nb2/3)O3‐PbTiO3 solid solutions are greatly affected by the formation of a liquid phase at ∼ 1290°C. Prolonged sintering at and above this temperature gives rise to an excessive PbO loss and the resultant variation in composition leads to an inhomogeneous microstructure. The inhomogeneity is characterized by the formation of a dense, localized region containing a PbO‐rich liquid near the surface with a porous interior region in the bulk of the sample.

Modelling Earthquake Ground Motions In Seismically Active Regions Using Parametric Time Series Methods, G. W. Ellis, A. S. Çakmak, J. Ledolter Jan 1987

Modelling Earthquake Ground Motions In Seismically Active Regions Using Parametric Time Series Methods, G. W. Ellis, A. S. Çakmak, J. Ledolter

Engineering: Faculty Publications

Strong motion accelerograms can be efficiently modelled using time series analysis. Because of the nonstationarity of accelerograms, transformations must first be applied to stabilize the variance and frequency content. An ARMA model can then be fit to the stabilized series. By analyzing a large number of accelerograms in California, these ARMA and transform parameters have been related to physical variables. Thus it is possible to generate simulated ground motions in the area studied. The validity of the modelling process is measured by comparing the simulations and their frequency spectra to actual records.


Bridge Decks And Overlays, James H. Havens, Theodore Hopwood Ii, Edgar E. Courtney Jan 1987

Bridge Decks And Overlays, James H. Havens, Theodore Hopwood Ii, Edgar E. Courtney

Kentucky Transportation Center Research Report

The report presents a historical perspective of the Transportation Cabinet's bridge deck construction and maintenance efforts directed toward increasing bridge deck durability.

Bridge decks crack in specific patterns that primarily depend upon bridge designs. Normal deck cracking is due to load-induced and thermal effects. Each type of cracking has a distinct pattern.

One-hundred and nineteen experimental bridge deck overlays were inspected. Included were 9 membrane bridges, 87 latex concrete overlays and 23 low-slump overlays. The overlays had been placed originally on both new and existing bridge decks on various routes throughout the state. Most of the overlays were rated in …


Thermomechanical Design Criteria For Zr02-Y203 Coated Surfaces, J. Padovan, Benjamin T.F. Chung, Glen E. Mcdonald, Robert C. Hendricks Jan 1987

Thermomechanical Design Criteria For Zr02-Y203 Coated Surfaces, J. Padovan, Benjamin T.F. Chung, Glen E. Mcdonald, Robert C. Hendricks

Mechanical Engineering Faculty Research

Thermocycling of ceramic-coated turbomachine components produces high thermomechanical stresses that are mitigated by plasticity and creep but aggravated by oxidation, with residual stresses exacerbated by all three. These residual stresses, coupled with the thermocyclic loading, lead to high compressive stresses that cause the coating to spall. In the paper a ceramic-coated gas path seal is modeled with consideration given to creep, plasticity, and oxidation. The resulting stresses and possible failure modes are discussed.


Automated Data Acquisition For Low-Volume Road Inventory And Management, Theodore Hopwood Ii, Gary W. Sharpe, John W. Hutchinson, Robert C. Deen Jan 1987

Automated Data Acquisition For Low-Volume Road Inventory And Management, Theodore Hopwood Ii, Gary W. Sharpe, John W. Hutchinson, Robert C. Deen

Kentucky Transportation Center Research Report

Local governments need suitable inventories and condition surveys to accurately determine and prioritize their funding needs. An efficient method of performing an inventory of the roads and subsequently determining the condition of major system components is to use an automated data-acquisition system to measure and record essential data. The data may be collected and processed by a central inventory management group. The inventory should include pavement characteristics, roadway geometries, and roadside features. Pavement condition may include structural integrity, road roughness, and skid resistance. Roadway geometries include horizontal curvature, length, width, superelevation, and grade. Roadside features include signing, intersections, guardrails, and …

Experimental And Theoretical Studies On Design Calculations For Latent Heat Storage, Dieter Lindemann Jan 1987

Experimental And Theoretical Studies On Design Calculations For Latent Heat Storage, Dieter Lindemann

Open Access Theses

Research was conducted to obtain design data of latent heat-of-fusion thermal energy storage (LHTES) devices. The devices studied utilize a porous medium (PM) to increase the effective conductivity of the storage system. Therefore the melting and freezing process is accelerated. Metal shavings and metal spheres were used as porous media and water as the phase change medium (PCM). A simple experimental method to measure the conductivity of a water-metal mixture or ice-metal mixture was applied to obtain conductivity data. These measurements can be considered fairly accurate because measured conductivity of pure water and of pure ice agreed very well with …

Chromate Adsorption On Amorphous Iron Oxyhydroxide In The Presence Of Major Groundwater Ions, John M. Zachara, Donald Girvln, Ronald Schmidt, C. Thomas Resch Jan 1987

Chromate Adsorption On Amorphous Iron Oxyhydroxide In The Presence Of Major Groundwater Ions, John M. Zachara, Donald Girvln, Ronald Schmidt, C. Thomas Resch

United States Department of Energy: Publications

Chromate adsorption on amorphous iron oxyhydroxide was investigated in dilute iron suspensions as a single solute and in solutions of increasing complexity containing CO2 (g), SO42-(aq), H4Si04(aq), and cations [K+, Mg2+, Ca2+(aq)]. In paired-solute systems (e.g., CrO42- =H2CO3*), anionic cosolutes markedly reduce CrO42- adsorption through a combination of competitive and electrostatic effects, but cations exert no appreciable influence. Additionally, H4Si04 exhibits a strong time-dependent effect: CrO42- adsorption is greatly decreased with increasing H4SiO4 …

Belief Maintenance Systems: Initial Prototype Specification, Roseanne M. Fulcomer, William E. Ball, John P. Tadlock Jan 1987

Belief Maintenance Systems: Initial Prototype Specification, Roseanne M. Fulcomer, William E. Ball, John P. Tadlock

All Computer Science and Engineering Research

A fundamental need in future information systems is an effective method of accurately representing and monitoring dynamic, real-world situations inside a computer. Information is represented using an Extended Open World Assumption (EOWA), in which the data are explicitly true or false. Reasoning within the EOWA is done through the use of a dynamic dependency net which only represents those beliefs and justifications that are both currently valid and in current use. In this paper, we present definitions and uses of the EOWA and dynamic dependency net in our current research of developing a database with which we can use deductive …

"Reduction of peak demand on utility systems can be beneficial to both utilities and customers. One means of achieving peak demand reduction is by the use of load-leveling batteries. This thesis describes the technical and economic factors for demand side, customer-owned battery energy storage systems. The thesis has taken into account battery costs, converter and balance of plant costs, current utility rates, and customer load profiles typical of those for which battery storage may be feasible. Battery storage system designs and costs were described and quantified by using the results of EPRI project 1275-12. Utilities in the midwest were selected …


Statistical Analysis Of A Compound Power-Law Model For Repairable Systems, Max Engelhardt, Lee J. Bain Jan 1987

Statistical Analysis Of A Compound Power-Law Model For Repairable Systems, Max Engelhardt, Lee J. Bain

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Conclusions - A compound (mixed) Poisson distribution is sometimes used as an alternative to the Poisson distribution for count data. Such a compound distribution, which has a negative binomial form, occurs when the population consists of Poisson distributed individuals, but with intensities which have a gamma distribution. A similar situation can occur with a repairable system when failure intensities of each system are different. A more general situation is considered where the system failures are distributed according to nonhomogeneous Poisson processes having Power Law intensity functions with gamma distributed intensity parameter. If the failures of each system in a population …


Simultaneous System Identification And Decision-Directed Detection And Estimation Of Jump Inputs To Linear Systems, Wynn C. Stirling Jan 1987

Simultaneous System Identification And Decision-Directed Detection And Estimation Of Jump Inputs To Linear Systems, Wynn C. Stirling

Faculty Publications

A decision-directed approach is presented for analyzing linear systems with unknown jump inputs. The system model parameters are estimated using a Kalman filter, and an empirical Bayes detection procedure is introduced to set the detector parameters, resulting in a decision-directed generalized likelihood ratio test coupled with recursive system parameter estimation. Monte Carlo results are presented to validate the performance of the algorithm.


A New Approach To Signal Registration With The Emphasis On Variable Time Delay Estimation, Mohamad Namazi, John A. Stuller Jan 1987

A New Approach To Signal Registration With The Emphasis On Variable Time Delay Estimation, Mohamad Namazi, John A. Stuller

Electrical and Computer Engineering Faculty Research & Creative Works

Signal Registration is Concerned with the Problem of Estimating a Varying Displacement between Two Random Processes. We Approach Signal Registration Here as a Recursive Demodulation Problem in Which the Recursion is between Signal Estimations and Displacement Estimation. Special Attention is Given to the Problem of Estimating a Variable Time Delay. Thus, We Present New Algorithms for Estimating D(T) from Received Processes:

r1(t) = s(t) + n1(t)

R2(t) = s(t - D(t)) +n2(t)

Where s [Formula Omitted] is Signal and n1 (•) and n2 (•) Are Noise. Simulation Results Are Presented …
