Abstract: Separation of crack growth signals is of fundamental importance for detecting, locating, and determining the significance of an internal flaw using acoustic emission techniques. The methodology used to determine the acoustic ...

Abstract: In previous work, it is reported that increased dilution at midrange injection pressures produces longer first stage combustion duration. There is also corresponding decreases in nitric oxide ...

Abstract: This paper presents the results of an undergraduate civil engineering curriculum revision at the Georgia Institute of Technology. The process of revision included a variety of important constituencies that provided important ...

Abstract: Most of the myriad (order of 109) interconnected coronary vessels interact nonlinearly with their embedding contracting myocardium. Their dynamic flow can be simulated based on a nonlinear ...

Abstract: This paper presents an overview of a finite-element-method (FEM) approach for the calculation of the dynamic stiffness of circular, externally pressurized gas thrust bearings with a nonuniform ...

Abstract: Although low-temperature premixed compression ignition (PCI) combustion in a light-duty diesel engine offers dramatic and simultaneous reductions in nitric oxides (NOx) and soot, associated increases ...

Abstract: This research uses laser ultrasonic techniques to develop transfer functions that remove the effect of geometric features on experimentally measured Rayleigh waves. These transfer functions are developed using a repeatable, ...

Abstract: This research uses laser ultrasonic techniques to study the effect of aggregate size on the attenuation of Rayleigh surface waves in cement-based materials. The random, multiphase, and heterogeneous nature of cement-based ...
