Evaluation of carbon fiber laminates via the use of pulse-echo ultrasound to quantify ply-stack orientation and manufacturing defects.
(2021-11-10)
The use of carbon fiber composites have become more prevalent. Laminated composites provide advantages over traditional materials as the final properties of the part can be tuned. These materials also provide new challenges ...
Numerical and theoretical study of natural oscillations of supported drops with free and pinned contact lines.
(2021-04-19)
The oscillation of drops supported by solid surfaces is important to a wide variety of applications, such as dropwise condensation. Identification of the natural frequencies of supported drops of different sizes and liquids ...
On the performance of convolutional neural networks initialized with Gabor filters.
(2021-08-05)
Over the years, image recognition has been gaining popularity due to its various possible usages. Convolutional Neural Networks (CNNs) have been the classic approach taken on by many researchers because of their capability ...
Neural network watchdog for out-of-distribution input mitigation.
(2021-10-19)
Neural networks have often been described as black boxes. The prevalence of publicly available neural networks and the application of transfer learning has allowed for the development of systems with minimal understanding ...
Static analysis-based software architecture reconstruction and its applications in microservices.
(2021-08-10)
Microservice architecture (MSA) is the predominant building block of modern cloud-based enterprise applications. MSA has several advantages over monolithic applications like scalability and maintainability, but it comes ...
Study of pumping conditions on output of optically pumped interband cascade lasers.
(2021-08-08)
This thesis presents the results of optically pumping two interband cascade laser (ICL) semiconductor samples and measuring both their output power and spectral data. The samples were prepared by the Naval Research Laboratory ...
Variation of cold-soaked fuel frost roughness with location on a flat plate.
(2021-11-09)
Cold-soaked fuel frost occurs when moist air flows over an aircraft surface that is colder than the dew point temperature following a flight. Previous studies show that cold-soaked fuel frost depends on surface temperature, ...
The influence of vapor pressure on droplet contact dynamics on smooth surfaces.
(2021-07-14)
Droplet impact experiments were performed with different fluids using Total Internal Reflection Microscopy (TIRM) on a smooth surface to gain insight into the mechanism for the air film failure of volatile liquids. Several ...
Design, simulation, construction, and measurement testing of fast-reconfigurable radio frequency switched-stub matching networks.
(2021-04-21)
Today’s world is increasingly dependent on wireless communications, and fifth generation (5G) cellular technologies have recently entered the picture. Part of their designated spectrum overlaps with that of S-band radar ...
Reducing the size and power of stochastic computing neural networks through training.
(2021-08-01)
It has been demonstrated that stochastic computing (SC) has the ability to reduce the size and power requirements of artificial neural network (ANN) circuits [1]. There are two prevailing SC neuron topologies: multiplexer ...
