Taylor-Galerkin Method for Wind Wave Propagation
Recently Taylor-Galerkin method has been used to successfully solve advection-dominated flow problems. This method performs quite well in reducing numerical dissipation and numerical dispersion...

On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...

Quantitative Stereology of Concrete Microcracking
Stereological methods enable extrapolation of quantitative microcrack characterization from two dimensions to three dimensional space. However, because these quantifying techniques are...

Behaviour of Prestressed Concrete End Blocks
This paper briefly reports on a series of experiments carried out on strip-loaded prestressed concrete end blocks. The results show that corresponding design methods presently used in...

Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...

Wavelet Transform Analysis of Several Transient or Nonstationary Phenomena in Engineering Mechanics
Several examples of the use of a wavelet transform in the analysis of transient events in mechanical systems are provided. The transform has the advantage over other transient analysis...

Experimental Photoelastic Analysis of Tunnels Containing Cracks
Due to the presence of cracks the strength of the structure is decreased in the present paper an experimental two dimensional photoelastic technique has been developed to analyze the circular...

Complementary Potentials of Finite Elasticity
The principles of virtual displacements and forces are embodied in a functional P. The complementary potential P_c is defined by the equation; P_c...

Nonstationary Response Characteristics of Linear MDOF Systems
A new approximate methodology for nonstationary random vibration analysis of multi-degree-of-freedom linear systems is developed. Simple analytical expressions for the covariance response...

Anatomy of the Loma Prieta Earthquake Records of Two Steel Buildings Using MIMO System Identification
The Loma Prieta strong-motion records of a 4-story and a 47-story steel building are analyzed using system identification. A time variation study from the 4-story building records reveals...

Stability of Systems of Rigid Bodies by Bounding Theorems
The stability of systems of systems of rigid bodies subjected to conservative and dissipative forces is investigated by considering the minimization of a work function subject to the kinematic...

An Expert System for Impeller Mechanical Design and Analysis
Impeller is the most critical component of centrifugal compressors. The mechanical efficiency and durability of the impeller determines the performance of the compressors. The shapes and...

Finite/Macroelement Meshes in Neural Rat Growth
The well known attributes of neural rat growth during 7 to 14 days postnatally are used to demonstrate the decrease in calculated growth discontinuities with macro, as opposed to finite,...

Form Comparison Without Anatomical Landmarks
The mathematical basis for various morphometric interpolating techniques is discussed. A technique, which enables analysis of biological forms without homologous anatomical landmarks,...

Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...

Genesis: The Creation of a Lunar Base
A lunar basing scenario that utilizes lunar resources to manufacture lunar concrete modules is considered. An eleven year basing program, starting with initial robotic exploration and...

Lunar Oasis
The Lunar Oasis emphasizes development toward self-sufficiency in order to reduce dependence on the Earth for resupply and to enable expansion utilizing indigenous resources. The Oasis...
