Traditional electronic systems are usually fabricated via printed circuit boards (PCBs). In a regular PCB, the electronic components are placed and mounted on a two-dimensional board. Such a component layout limits the freedom in the component placement process which results in larger electronic devices. With the use of Additive Manufacturing...
This study is primarily concerned with the measurement of the local radiative component of total heat transfer around a horizontal tube immersed in a large particle fluidized bed at elevated temperatures.Total heat transfer was also measured in order to assess the relative radiation contribution.The radiation measurement probe employs a silicon...
Photonic sintering of nanoparticles is a relatively new process for sintering of nanoparticles, deposited on a substrate, into functional solid structures. The working principle of this process is the incidence of large-area broad-spectrum light onto deposited nanoparticles, which results in heat generation in the nanoparticles and their subsequent densification. Key...
A common problem in energy allocation problems is managing the trade-off between selling surplus energy to maximize short term revenue, versus holding surplus energy to hedge against future shortfalls. For energy allocation problems, this surplus represents resource flexibility and is quantified as the surplus energy after meeting the demand. The...
Sintering of nanoparticles to create films and patterns of functional materials is emerging as a key manufacturing process in applications like flexible electronics, solar cells and thin-film devices. Further, there is the emerging potential to use nanoparticle sintering to perform additive manufacturing as well. While the effect of nanoparticle size...
Renewable energy sources are becoming increasingly important due to their low environmental impact and limitless nature. This thesis explores the design of a 250 mW permanent magnet linear generator wave energy converter to power ocean sensors. While many wave energy converters exist, this is a unique application because the wave...
Predicting condensation flow regimes and the associated heat transfer and pressure drop in microchannels is critical for designing terrestrial and space systems for heating, cooling, power generation, and advanced manufacturing. It is well established that in flows approaching the microscale (Dh < 1 mm) gravity-dominated flow regimes become less relevant,...
This thesis covers the use of a quarter car model to select damping rates for aFormula Student (FS) car, focusing on minimizing vertical tire force variation to improvegrip. A 2 degree of freedom (DOF) quarter car model is cycled over the road frequenciesof interest and the results compared with the...
There is growing commercial interest in the use of unmanned aerial vehicles (UAVs) in urban environments, specifically for package delivery applications. However, the size, complexity and sheer numbers of expected UAVs makes conventional air traffic management that relies on human air traffic controllers infeasible. To enable UAVs to safely and...
Offshore renewable energy (ORE) has the potential to be a significant source of future global electricity production, reduce carbon emissions, decrease dependence on energy importation, and stimulate economic growth in coastal and remote areas. The availability and abundance of ORE, paired with growing coastal population centers, position offshore wind, wave,...
This thesis uses the manuscript option, and consists of a previously-published paper and a paper that has been accepted for publication. Manuscript One details an independent confirmatory study to Choo et al. (2014), which demonstrated that correlations exist between personality type and the outcome of concept ideation methods. This is...
This work is a culmination of a series of published works related to the use of the Material Point Method (MPM) in modeling wood adhesive bonds. The use of wood as construction material has the potential to play a small role in the solution to the current CO2 and climate...
Adequate lubrication is of the utmost importance in internal combustion engines. Low temperature operation with low-proof alcohol may create some operational problems if alcohol and or water accumulates in the crankcase oil. Condensates of unburned alcohol and water may be blown into the crankcase oil with blow by gases. The...
Metal organic Frameworks (MOFs) that experience stimuli induced structural transformation could enable a whole new class of materials with remarkable properties. Photoactuating moieties in the structure could effect changes in the pore space or macroscale shape change enabling light driven gas separation and actuators. Here, we present a novel approach...
This research presents a methodology to analyze customer needs and direct the gathering of customer needs that both span the need space and are independent. An ontological categorization, the fundamental research contribution of this work, is created to support both aims of the overall methodology. Providing designers with a customer...
Concentrated solar power (CSP) plants have the potential to reduce the reliance on nonrenewable energies such as coal and natural gas and provide 24 hour, renewable electricity. A CSP system consists of a large field of heliostats that concentrate the sunlight on a centralized receiver, in this receiver a working...
Diffusion bonded microchannels provide significant benefits by reducing space requirements while improving thermal efficiency when used in heat exchangers. In particular, these microchannels have potential to improve efficiencies for combining concentrated solar power with supercritical CO2 Brayton cycles, where structures operate at high temperatures (760 ˚C) and high pressures (25...
This work develops the loads, boundary conditions, and model construction techniques used to create a high-level vehicle analysis model. The loads are derived from the overall performance parameters of the vehicle, which include 3 axis accelerations and aerodynamic forces from Computational Fluid Dynamics outputs. The boundary condition of the analysis...
Chainsaw users value cutting performance and safety. Knowledge of the forces exerted during sawing are necessary to understand and improve the cutting performance of saw chain. Additionally, cutting forces can be used to form metrics for evaluating performance tradeoffs when using a safety (i.e. low-kickback) saw chain versus a standard...
Assembly planning is a crucial task for every manufacturing product. In general, assembly operations consume more than 30% of the total manufacturing time and cost. Therefore, any effort in optimizing assembly will have a significant impact on the economic success of manufacturing. Finding an optimal assembly plan by hand is...
