Practical Optical Survey Strategies For Near Geostationary Orbital Debris, Akhter Mahmud Nafi 2020 Utah State University

Practical Optical Survey Strategies For Near Geostationary Orbital Debris, Akhter Mahmud Nafi

All Graduate Theses and Dissertations

Uncontrolled space objects, more commonly known as space debris, consist of dead satellites, satellite deployment packages, and lost elements of these systems such as insulation blankets. These uncontrolled objects represent hazards to our nation’s most valuable space assets which include communication satellites, weather satellites, Earth monitoring systems, and military assets. To help mitigate this problem, this research proposes using the known astrodynamics of the near geosynchronous orbit (GEO) along with the known concentration of the uncontrolled GEO objects and observation constraints to design ground-based optical surveys that will detect uncatalogued debris. Furthermore, a scoring metric is developed to evaluate ...

Earth/Space Science - Earth's Place In Space: Seasonal Change, Elizabeth Martinez, Peg Steffen 2020 Illinois Mathematics and Science Academy

Earth/Space Science - Earth's Place In Space: Seasonal Change, Elizabeth Martinez, Peg Steffen

Model NGSS Lessons: 4th - 5th Grade

A key Disciplinary Core Idea for understanding our place in space is that the orbits of Earth and the sun and of the moon around Earth cause observable patterns. These include day and night; daily changes in the length of shadows; and different positions of the sun, moon, and stars at different times. There are many misconceptions about earth’s orbit but it is important to remember and to convey to students that Earth is moving around the Sun and the Moon is moving around us. What we see each day with the motion of the Sun moving across the ...


Integrated Photonic Device, Brittney Kuhn 2020 Chapman University

Integrated Photonic Device, Brittney Kuhn

Student Scholar Symposium Abstracts and Posters

In computer mediated communication networks, information is typically encoded optically to transmit signals over long distances. At a network node, the optical signal is transformed into the electrical domain, processed electronically, and transformed back to an optical state to reach its destination. Transitioning between optical and electrical encoding of the signal is a potential security weak point, especially for quantum communication links. If information can remain in one state as it travels through the network, then security breaches can be detected and dealt with more easily. Furthermore, keeping the information in one state can reduce power consumption in the network ...


A Linear Actuator/Spring Steel-Driven Glove For Assisting Individuals With Activities Of Daily Living, Daniel Chizhik 2020 University of Maine

A Linear Actuator/Spring Steel-Driven Glove For Assisting Individuals With Activities Of Daily Living, Daniel Chizhik

Electronic Theses and Dissertations

Over three million people in the U.S. suffer from forearm and hand disabilities. This can result from aging, neurological disorders (e.g., stroke), chronic disease (e.g., arthritis), and injuries. Injuries to hands comprise one-third of all work-related injuries worldwide. This can lead to difficulties with activities of daily living (ADL), where one needs to grasp, lift, and release objects in the household. There is a rise in demand for assistive orthoses and gloves that can allow many people to regain their grasping/releasing ability and, thereby, their independence. The main contribution of this thesis is developing an assistive ...


Unsteady Internal Ballistics Of A Hybrid Rocket, Naveen Sri Uddanti 2020 Embry-Riddle Aeronautical University

Unsteady Internal Ballistics Of A Hybrid Rocket, Naveen Sri Uddanti

Dissertations and Theses

With the recent progress made in the field of space tourism, hybrid rocket engines have gained a renewed interest due to their simplicity, low cost, operational flexibility, and safety. The flow in the ports of a hybrid rocket motor involves several coupled unsteady phenomena like moving walls, combustion in a boundary layer flow and mass addition along the port, through the regression of the solid fuel wall. The flow in the combustion chamber of a hybrid rocket is inherently unsteady because the geometry of the port varies as a function of space and time. In the current research, we develop ...

We believe that the application will aid students in a myriad of specific ways, including being involved in study groups and getting tutoring help, determining which classes ...


Using Taint Analysis And Reinforcement Learning (Tarl) To Repair Autonomous Robot Software, Damian Lyons, Saba Zahra 2020 Fordham University

Using Taint Analysis And Reinforcement Learning (Tarl) To Repair Autonomous Robot Software, Damian Lyons, Saba Zahra

Faculty Publications

It is important to be able to establish formal performance bounds for autonomous systems. However, formal verification techniques require a model of the environment in which the system operates; a challenge for autonomous systems, especially those expected to operate over longer timescales. This paper describes work in progress to automate the monitor and repair of ROS-based autonomous robot software written for an a-priori partially known and possibly incorrect environment model. A taint analysis method is used to automatically extract the data-flow sequence from input topic to publish topic, and instrument that code. A unique reinforcement learning approximation of MDP utility ...


Decoding Ldpc Codes With Probabilistic Local Maximum Likelihood Bit Flipping, Rejoy Roy Mathews 2020 Utah State University

Decoding Ldpc Codes With Probabilistic Local Maximum Likelihood Bit Flipping, Rejoy Roy Mathews

All Graduate Theses and Dissertations

Communication channels are inherently noisy making error correction coding a major topic of research for modern communication systems. Error correction coding is the addition of redundancy to information transmitted over communication channels to enable detection and recovery of erroneous information. Low-density parity-check (LDPC) codes are a class of error correcting codes that have been effective in maintaining reliability of information transmitted over communication channels. Multiple algorithms have been developed to benefit from the LDPC coding scheme to improve recovery of erroneous information. This work develops a matrix construction that stores the information error probability statistics for a communication channel. This ...

Investigating The Production Of Cores By Using Reclaimed Foundry Green Sand, Kristopher Lee Boss

Dissertations and Theses @ UNI

Increasing environmental regulations, transportation cost, delivery interruptions leading to production concerns, disposal cost, and demand from other industries have influenced the way foundry’s view used sand. The purpose of this research was to determine a beneficial reuse of overflow-green sand that would normally be disposed. The reclamation process used is a combination of mechanical and wet reclamation. The focus was on the production of foundry cold box cores and if using this reclamation process could create a core with a similar quality performance compared to new sand. Research in reclamation could pave the way for a closed loop sand ...

Performance Of A Precast Wall With End Columns Rocking-Wall System With Precast Surrounding Structure, Qingzhi Liu, Catherine W. French, Sri Sritharan

Civil, Construction and Environmental Engineering Publications

A large-scale structural assemblage was tested under quasi-static loading to investigate the seismic performance of a rocking-wall structure assembled by precast members. An innovative PreWEC (precast wall with end columns) system, which consisted of a precast non-bearing rocking wall, energy-dissipating O-connectors, and adjacent load-bearing end columns was used as the rocking-wall system. The structure surrounding the PreWEC included precast edge beam and columns and a floor system formed by untopped precast planks. Wall-floor connections were used to isolate the floor from vertical movements of the wall. Test results showed that the floor was successfully isolated from the uplift of the ...


Optimal Emergency Response Shelter Placement Based On Population Vulnerabilities, Alexander Johnson 2020 University of Arkansas, Fayetteville

Optimal Emergency Response Shelter Placement Based On Population Vulnerabilities, Alexander Johnson

Industrial Engineering Undergraduate Honors Theses

Hurricane Florence was a category 4 storm which caused an estimated $24 billion in damages and the loss of 53 lives. During and immediately following Florence, there were 235 shelters operating in and around the North Carolina (NC) area. These were used as temporary housing for storm victims and by emergency responders to distribute relief supplies and provide medical services. Emergency officials consider several factors when deciding where to open shelters, including, for example, proximity of victims and their levels of medical needs. Access disparities, or factors creating barriers that limit entry to shelters, put certain populations and regions at ...
