▼ In the last five years there has been a significant rise in the number of academic and extra-curricular programs that focus on developing technology-based long-term or infrastructure projects in economically underserved communities around the world. These ventures often fail because of disconnects between the designer, the implementer, and the end-user. There is a growing trend towards curricular and extra-curricular programs and student clubs that focus on appropriate technology-based projects to address the needs of marginalized communities. It is of crucial importance to the success of the venture to identify the optimum distribution of various kinds of equity that may be shared by the communities and partnering organizations. This thesis describes the Equilibrium Spot (E-Spot) Model, a method for identifying the appropriate stakeholders within a venture and defining their roles and responsibilities towards the venture. This model is the basis for the E-Spot Canvas, a design space and business strategy exploration tool. The canvas facilitates collective thinking amongst stakeholders to match project resource requirements with time, money, sweat, and other equities that can be expended by them to sustain their project socially, economically, and environmentally. The E-Spot Canvas serves three roles: 1) an educational tool for studying and practicing systems thinking; 2) an entrepreneurial tool for developing equitable business and implementation strategies; and 3) an ethical reflection tool for understanding motivations and incentives of various stakeholders and making decisions that optimize short-term and long-term benefit and minimize the risk for everyone involved. This thesis concerns the development and validation of the E-Spot Model and Canvas. The E-Spot Canvas is based on the systems-thinking tenets of interdependence, holism, multifinality, equifinality, differentiation, regulation, abstraction, and leverage points. I have delved into systems theory to compile and synthesize definitions of these tenets and have explained the linkages from a conceptual and practical perspective. I have piloted the E-Spot Canvas with about 80 students in various Humanitarian Engineering and Social Entrepreneurship (HESE) classes to obtain feedback and to refine it. Observations from fieldwork on HESE ventures in Kenya, Tanzania, and India have also been integrated into my entire endeavor. Three case studies have been presented in this thesis: a biogas digester, Kochia windmill project and Husk Power Systems (HPS). In addition, I have also examined application of the model to an Intelligent Street Lighting system.

Degree: 2011, Penn State University

▼ Electrodynamic tethers can be used to harvest energy onboard a spacecraft orbiting the Earth or any planetary body with a magnetic ﬁeld and surrounding plasma. The motion of the conductive tether in the Earth’s magnetic ﬁeld generates an electromotive force along the length of the tether. The ionospheric plasma completes the circuit to allow current to ﬂow through the tether and, ultimately, through the energy-handling components on the spacecraft. This energy can be used immediately or stored in batteries, capacitors, ﬂywheels, or other storage devices. As current ﬂows through the tether, the spacecraft loses altitude due to the electrodynamic force created by the ﬂow of electrons in the magnetic ﬁeld. One can think of the electrodynamic tether system as transforming orbital potential energy into electrical energy. The system can regain the lost altitude by forcing current to ﬂow against the generated electromotive force, creating a thrust in the direction of motion. Electrodynamic tether systems can augment a spacecraft’s performance or enable capabilities that were previously unobtainable, such as energy harvesting while in the Earth’s shadow. The objectives of this research were to evaluate the feasibility, performance, trade-oﬀs, and net beneﬁt of electrodynamic-tether power generation for space missions. Speciﬁc objectives included creating system concepts for various classes and sizes of spacecraft, characterizing eﬃciencies, and comparing alternative storage technologies. Our research has found that large satellites have the potential to harvest as much as kilowatts of power at some load. Small electrodynamic tether systems the size of CubeSats have the potential to harvest 50% more energy than solar panel systems alone and can produce over 40-watts-average power useful during, for example, a 10-minute ground station overpass. An energy storage module was added to our simulation software that models physical storage devices, such as supercapacitors and lithium–ion batteries, and a generic device. It also investigates orbital energy concepts such as in-plane energy changes, energy needed to torque an orbit, and the conservation of energy as orbital energy is transferred into electrical energy. In spite of the enhanced capabilities provided to orbiting spacecraft by electrodynamic tether systems, signiﬁcant research remains to realize the promise of electrodynamic tether systems as a unique solution to the energy needs of satellites.

▼ Cube satellites (CubeSats) have increased in popularity in recent years as a tool for space research and education. Students and faculty at Penn State's Student Space Programs Laboratory (SSPL) have been developing the Orbital Satellite to Investigate the Response of the Ionosphere to Stimulation and Space weather (OSIRIS-3U) CubeSat. By measuring the spatial and temporal response of the ionosphere using in situ and remote sensing instruments, OSIRIS-3U will help answer questions on plasma transport in the stimulated ionosphere. This work focuses on the mission development and incremental development of a science instrument for OSIRIS-3U. Mission development is a balance between system capabilities and desired measurements to meet the mission objectives. Building a system model is key to understanding system sensitivity to tradeoffs of operational time to power usage, and numbers of orbits through a science region to generated data volume. A Monte Carlo simulation of the OSIRIS-3U mission in AGI's Satellite Tool Kit (STK) provides the data points to observe and analyze system sensitivities using the Applied Research Laboratory's Trade Space Visualizer (ATSV) tool. This understanding is required to develop a clear set of requirements to guide future system development and implementation. The OSIRIS-3U system carries three primary instruments to address the science question including a Langmuir probe (LP) developed at Penn State, a UHF beacon developed by the Naval Research Laboratory, and an occultation instrument developed by The Aerospace Corporation. Previous work has been done at Penn State to develop another instrument that combines the LP with a plasma impedance probe (PIP), providing increased mission flexibility in small volumes such as on CubeSats. The present work incrementally builds on previous work at Penn State by building, calibrating, and testing the PIP and comparing the results with a network analyzer and laying a path for future development.

▼ The field of protocol analysis arose from the increasing need for network security. Analysis and identification of the protocols of traffic on a network allowed for some classification of whether or not the behavior on the network was permissible. This type of protocol classification can address similar needs in the software-defined radio space as well as in various military applications. In these, as well as many other, applications there is a need to classify the protocol of an unknown wireless signal and to provide some general insights into the activity that is present on such signals. To this end, a protocol detection system was developed to compare the protocol of an unknown set of recorded packet traces to a set of known and previously characterized protocols. The basis for this detection system was the concept that protocols can be defined by the related sets of packets that get transmitted between the client and server of a connection. Many protocols have a request-and-response communication structure in which one side of the connection, often the client, is requesting data from the other, often the server. In the case of the server sending command or configuration packets to the client device, there are often sets of acknowledgment packets that follow this request-and-response structure. This system was designed to analyze a network trace using an unknown protocol by comparing the packets to the request-and-response structure of previously characterized, known protocols. By determining how similar the unknown protocol traffic is to known protocols, a detection decision can be made based on the number of packets that are identified as belonging to each of the known protocols. This approach is shown to be relatively successful for the limited, available sets of network traces that were recorded for this research. Packet trace lengths of greater than 200 packets are shown to provide a sufficient amount of detection accuracy when comparing an unknown trace to the Bluetooth and ZigBee protocols. However, there is much room for improvement for this system in its detection-decision criteria.

▼ Engineering design idea-generation sessions often result in dozens, if not hundreds, of ideas. These ideas must be quickly evaluated and filtered in order to select a few candidate concepts to move forward in the design process. While creativity is often stressed in the conceptual phases of design, it receives little attention in these later phases – particularly during concept selection. This is largely because there are no methods for quickly rating or identifying worthwhile creative concepts during this process. Therefore, the purpose of this thesis was to develop and test a novel method for evaluating the creativity and feasibility of design concepts. The first phase of this research involved the creation of a creativity evaluation methodology that utilizes word selections and semantic similarity to quickly and effectively evaluate candidate concepts. To test its utility during concept selection, an empirical study with ten engineering designers was completed. The results revealed that our methodology and rating system could be used as a proxy for measuring design creativity regardless of the openness of the design task. The second phase of this thesis sought to investigate the impact of decision-making bias during concept selection and to refine our design creativity evaluation methodology. In order to accomplish this, an online questionnaire was developed and administered to 11 expert and 11 novice design engineers. The results from this study supported the use of our creativity evaluation methodology with both expert and novice raters for early design creativity. It also contributes to our understanding of experience bias in creativity evaluation and provided a framework for computational design creativity systems. The final phase of this thesis sought to explore the use of the creativity assessment methodologies within a classroom setting and to compare the results from team evaluations and individual team member evaluations. During this phase, our creativity evaluation methodology was developed into a printable toolkit to help students evaluate designs for an in-class project. In this study, 32 students in teams of four utilized the toolkit to analyze design sketches from their team members. The results from this study showed significant relationships between individual and team perception based evaluations that utilized sliding scales and group discussion and our adjective selection method. However, the widely adopted creativity evaluation method from academia that compared designs feature by feature appeared to be measuring something else entirely. The results from this thesis are used to develop recommendations for the use of creative concept selection tools in engineering design. In addition, the results are extrapolated to create recommendations for an online web application geared enhancing the usability and accessibility of concept selection tools for both academic and industrial implementation.

▼ Ion thrusters are able to provide low thrust and high specific impulse, making them suitable for station keeping missions and interplanetary travel. One important feature of this type of space propulsion is the emission of charged particles away from the spacecraft, requiring the use of a neutralizer emitting electrons in order to ensure thrust. This thesis presents the design and testing of a microwave miniature of ion thruster using an electron cyclotron resonance discharge. The propellant (argon or xenon) flows inside a discharge chamber at an operational mass flow rate of 0.15 sccm and is then ionized by the coupling between an oscillating electromagnetic field of frequency 5 GHz fed by a ring-type antenna and a permanent magnetic field created by two concentric magnets. Only 4 W of total absorbed power is required to obtain ionization of the plasma, and 0.4 W to sustain it. The plasma created then is accelerated through a pair of grids that have a given potential across them. Our device can operate either in an ion thruster mode, accelerating the argon or xenon atoms, or in an electron emission mode, accelerating only electrons. In the ion thruster mode the thruster is predicted to produce a thrust of 217 μN with a mass utilization efficiency of 46% and a total efficiency of 75% if the propellant used is argon. A numerical analysis of both the permanent magnetic fields and electromagnetic radiation inside the discharge chamber was also conducted. It was found that the thickness of the yoke plate to which the magnets are connected does not have any effect on the magnetic field inside the chamber and that the the antenna had to be positioned 2 mm away from the magnets in order to provide the best permanent magnetic field-electromagnetic radiation coupling. The electromagnetic radiation simulation also allowed us to validate the design of the microwave antenna.

▼ The design of an 8-GHz Microwave Electrothermal Thruster was studied and optimized via numerical modeling. The electromagnetics of the thruster was modeled in an effort to develop and optimize a thruster design that would produce a robust electric field and resonate at the mode shape. The fluid dynamics of the MET propellant injection system were modeled in two and three dimensions. The electromagnetics study investigated multiple designs and configurations in an effort obtain a robust mode shape with an intense electric field concentration at the nozzle end of the thruster cavity. Models using both coaxial and waveguide ports for microwave energy inputs were investigated and optimized. It was found that though the coaxial input provided a stable mode, a much stronger electric field could be obtained by coupling a waveguide to a coaxial port. Also, using a waveguide short, the result could be fine-tuned. The design was optimized through testing different waveguide sizes and varying the antenna depth in the chamber. It was also found that the electric field intensity varied based upon the amount of dielectric in the cavity. Also, the resonant frequency increased when using a dielectric with a higher dielectric constant, but had little effect on the electric field intensity. In the fluid dynamic analysis, three-dimensional models were developed for the propellant injection system using incompressible and weakly compressible fluid flow assumptions. A viscous compressible flow model was being developed using the governing equations: mass, momentum, and energy. Both two- and three-dimensional compressible flow models were developed; however, a three-dimensional compressible flow model was not completed. Future recommendations are made for future modeling efforts in completing the three-dimensional compressible flow modeling, as well as moving forward toward developing a numerical model that encapsulates the coalesced plasma characteristics that a physical prototype demonstrates.

▼ Research has been conducted on the microwave electrothermal thruster at The Pennsylvania State University since the 1980’s. Each subsequent thruster incorporated modifications that resulted in improvements in thruster performance compared to previous generations. Operational frequencies evaluated thus far include 2.45 GHz, 7.5 GHz, 8 GHz, and 14.5 GHz. As each thruster increased in operational frequency, plasmas have been ignited with successively lower amounts of input power. With higher frequency and lower power requirements, the physical sizes of the thruster and the power supply have been reduced. Decreased size results in a lighter propulsion system, which is ideal for space missions. This thesis concerns the design and development of a thruster operating at 30 GHz. Electromagnetic modeling was used in the design of the thruster to determine the optimal input antenna size and length. A 2.4-mm antenna size was chosen with a length that is flush with the bottom of the cavity. Modeling also aided in the understanding of how machining accuracy of the cavity radius affects thruster performance. The modeling results indicated that radius inaccuracies on the order of ±0.1 mm result in mode distortion, shifting of the resonant frequency, lowered electric field strength, and poor power transfer to the cavity. The experimental setup for the thruster system, propellant system, electromagnetic system, and pressure system are discussed. The 30-GHz MET has an approximate radius of 0.4 cm and height of 1.4 cm. The expected power requirement for plasma ignition is 5–10 watts. Scaling down the thruster size resulted in different adapters and enhanced pressure sealing requirements when compared to previous METs. Initial testing is being performed at a pressure of 30 Torr using helium as the propellant. A network analyzer was used to determine the exact resonant frequency of the cavity and to determine the power coupling to the cavity. The exact resonant frequency of the cavity is 29.939 GHz. The initial setup of the thruster indicated a power coupling of 6 dB while reducing the length of the antenna resulted in enhanced power coupling of at least 25 dB. The fabrication and testing of this thruster gave rise to many design improvements that are also discussed.

▼ The direct thrust output, efficiency, and specific impulse of an 8-GHz microwave electrothermal thruster (MET) was measured using a vertical thrust stand in an evacuated vacuum tank. Measurement was done by assembling a vertical thrust stand board inside a vacuum chamber. The thruster was mounted via flexible WR-112 waveguide to 1-kg load cell. Pressure was evacuated from the chamber to levels of 0.1 Torr and plasma was formed using ammonia and decomposed-ammonia simulated hydrazine as propellants. Thrust measurements were taken at previously determined parametrically optimized values and reconciled against predicted values computed from pressure differential calculations. The 8-GHz MET uses the resonant TMz011 mode to excite a propellant gas into a free-floating plasma. Due to density gradients and buoyancy issues in the plasma chamber, a vertical thrust stand was employed in order to obtain maximum thrust values. This constraint provided several challenges in thrust stand design, including cavity redesign, load cell sensitivity issues, and vibration noise issues caused by the vacuum chamber pump. Cavity redesign also allowed for materials optimization, including the reconstruction of the cavity using stainless steel for its better electrical properties, and a boron nitride separation plate. A converging–diverging nozzle with an area ratio of 25:1 was also included in the design to get more realistic operational values. Thrust measurements in most cases were within 20% of predicted values and yielded more repeatable results than previous thrust measurements using deflection cones and momentum traps. While some of this error could be accounted for with measurement uncertainty, this is still too large of a discrepancy between theoretical and measured values. Incorrect assumptions of the mixture dynamics for physical constants in calculations, thermal biasing of the load cell, vibration and electrical noise as sources of error all need to be explored and eliminated.

▼ A wire-mesh reactor with constant-current heating and non-thermal plasma assistance is described. The apparatus is capable of combining resistance heating and dielectric barrier discharge on solid or powder test samples. DC current that is variable between 0 and 180 amps is used for heating, and a thermal camera is used to capture heating rates and local heat distributions. AC voltage up to 30 kV is injected at frequencies between 0 – 10 kHz to generate a dielectric barrier discharge. The reactor provides an experimental setup enabling combustion as well as pyrolysis without the need for removing the oxygen from the environment.\par Experiments are carried out in the reactor on coal dust particles to demonstrate substantial profit on cold-start by the effects of dielectric barrier discharge. Ignition time for coal samples decreased with plasma present as opposed to no plasma. Thermal camera measurements indicate an increased rate of change of temperature, translating to a significant decrease in input power. To study the effect of the plasma on coal samples during combustion, results were obtained with a constant-current supply applied to samples under resistance heating. Additional experiments were performed with varying input current to understand the mechanisms of plasma assisted combustion. The physical interaction between non-thermal plasma and fine solids or dust particles in cold-start has yet to be described experimentally. As the energy industry reforms from fossil fuels to biofuels, plasma assisted combustion on solid or dust samples can be used as an alternative to traditional energy transformation. Several combustion systems incorporate plasma treatment before and during combustion with noble gases such as argon and helium. A system applying the same principles on molecules in their solid-state of matter is a promising alternative in the reforming energy industry.
