(2013-09-19)The brake torque of a direct-injection diesel engine is known to plateau over a range of injection timings. Injection timing affects the engine’s ignition delay and the fractions of fuel which burn in premixed and diffusion ...
-
(2012-07-16)The Riverside Energy Efficiency Laboratory at Texas A&M University conducts sound quality testing for the Home Ventilating Institute. When the Home Ventilating Institute initially established their sound quality test, the ...
-
(2016-08-09)Microfluidic acoustophoresis is a nonlinear acoustic phenomenon that can induce the motion of microparticles or cells under acoustic excitations in microfluidic devices. Existing acoustophoresis models, which are derived ...
-
(1983)This report is a study of the development of an active, adaptive noise control system for a 4" I.D. duct. The study yielded the development of a series of circuits to be incorporated with a microprocessor in a continuous ...
-
(2013-08-06)In order to obtain sustainable engineering systems, this research investigates surface and interface properties of metals and active nanostructured coatings. The goal is to develop new approaches in order to improve the ...
-
(2017-12-06)In this work, a new concept was explored for the optimization of heating, ventilating, and air-conditioning (HVAC) systems in buildings. The methods assume that only commonly trended sensor data would be available and that ...
-
(2010-01-16)Recently, active suspension has been applied to many commercial automobiles. To develop the control algorithm for active suspension, a quarter-car test bed was built by using a direct-drive tubular linear brushless ...
-
(2009-05-15)A novel active material for controllable, high work density applications was designed, fabricated, analyzed, and tested. This active material uses a lens-shaped element to implement simple shear motion with gas pressure ...
-
(2011-08-08)The subject of this thesis is an extension of a two-dimensional, axisymmetric, Timoshenko-beam finite-element rotordynamic code to include a three-dimensional non-axisymmetric solid-element casing model. Axisymmetric beams ...
-
(2011-10-21)Disability is seen as a result of an interaction between a person and that person's contextual factors. Viewing disability in the context of the built environment, a better design of this environment helps to reduce the ...
-
(2017-05-08)Product family design is a popular approach for designing a group of related products to strategically share common features and components. One method for developing product families is by using a combination of shared ...
-
(Texas A&M University, 2004-11-15)Quality of Service (QoS) in real-time media applications can be defined as the ability to guarantee the delivery of packets from source to destination over best-effort networks within some constraints. These constraints ...
-
(2009-05-15)Some numerical simulations of multi-scale physical phenomena consume a significant amount of computational resources, since their domains are discretized on high resolution meshes. An enormous wastage of these resources ...
-
(2016-07-12)Recent years have witnessed a phenomenal increase in research efforts in energy storage for vehicle electrification. Lithium batteries, such as lithium-ion and lithium-sulfur batteries are leading the race towards meeting ...
-
Addressing the Role of Electrode Microstructure in Li-Ion Battery Thermo-Electrochemical Interaction (2017-07-17)Lithium-ion batteries are a ubiquitous part of modern technology as portability and reusability are heavily emphasized. As this is the case, it is important to further improve their electrochemical capabilities while ...
-
(2012-02-14)The adhesive contact problems of a conical frustum punch indenting a transversely isotropic elastic half space and an orthotropic elastic half space are analytically studied in this thesis work. To solve the problem involving ...
-
(2016-07-12)Adhesive wear is one of the most difficult types to study and is especially challenging for polymers. Such wear processes involve the mutual sticking of surface asperities followed by removal of debris from the bulk. This ...
-
Advanced Exergy and Exergoeconomic Analysis of the Major Components of a Combined Cycle Power Plant (2015-11-30)For a power plant, or any energy conversion system, exergetic analysis methods are used to determine the irreversibilities, or exergy destruction, in the system components. Advanced exergetic analysis methods indicate that ...
-
(2018-08-03)Inhaling air-borne metal particles is known to cause adverse health effects such as cancer, pulmonary heart disease, and asthma, to name a few. Metal particles can be released to air from various additives often used to ...
-
(2020-11-10)The Mixing Coefficient (MC) is an uncertain, assumed parameter for predicting the leading-edge temperature of a pad film domain. The conventional approach, employing an assumed MC has shown limitations for accurately ...
