Anticipating impacts

Creator:: Hermens, Benjamin J.
Abstract:: We present an approach for generating a character’s response in anticipation of an impending impact. Protective anticipatory movement is built upon several simple actions that have been identified as response mechanisms in monkeys and in humans. These actions are parameterized by a model of the interaction based on the approaching...

Assessing Several Modeling Approaches in Depletion Studies of a TRISO-Fueled Microreactor

Creator:: Hoffman, Keenan J.
Abstract:: The impact of MCNP6 depletion resolution on core lifetime is examined in the context of the Snowflake microreactor with explicit TRISO fuel. The change in core lifetime and iso- tope mass as a result of different tracked isotopes, timesteps, and spatial regions is discussed. Calculation speed of a prototype MCNP...

Assessing the Feasibility of Utilizing UAS-Based Point Clouds for Pavement Smoothness/Roughness Quantification

Creator:: Sen, Fatih
Abstract:: Transportation agencies continuously strive to improve driving quality and highway safety, which are both highly correlated with the level of smoothness of the road. The International Roughness Index (IRI) is a widely adopted, standardized metric calculated from longitudinal profile data collected on the road. Inertial profilers are devices mounted to...

Branched Covering Space Construction and Visualization

Creator:: Golbabaei, Sanaz
Abstract:: Branched covering spaces are a mathematical concept which originates from complex analysis and topology and has found applications in tensor ﬁeld topology and geometry re-meshing. Given a manifold surface and an N-way rotational symmetry ﬁeld, a branched covering space is a manifold surface that has an N-to-1 map to the...

Commercialization potential of viscoelastic thermal compressed (VTC) wood

Creator:: Macias, Natalie R.
Abstract:: The increasing demand for forest products and restricted use of natural forests has resulted in a shortage of high-strength wood fiber. The area covered by plantation forests is steadily rising, but the fiber produced by these forests is often unsuitable for high-strength applications. One attempt to combat this problem is...

Computing Bounded Chains and Surfaces in a Simplicial Complex with Bounded-treewidth 1-skeleton

Creator:: Black, Mitchell
Abstract:: We consider three problems on simplicial complexes: the Optimal Bounded Chain Problem, the Optimal Homologous Chain Problem, and 2-Dim-Bounded-Surface. The Optimal Bounded Chain Problem asks to find the minimum weight d-chain in a simplicial complex K bounded by a given (d−1)-chain, if such a d-chain exists. The Optimal Homologous Chain...

Corporate social responsibility and its implementation : a study of companies in the global forest sector

Creator:: Han, Xiaoou
Abstract:: Corporate social responsibility (CSR) can be defined as companies acting in accordance with societal demands. In recent years, CSR has gradually become a leading issue in business. Heightened corporate attention to CSR has not been entirely voluntary. Many companies awoke to it only after being surprised by public response to...

Cost-Age-Time Data Organized Garbage Collection

Creator:: Lee, Dongjun
Abstract:: NAND flash based solid state drives (SSDs) require out-of-place updating due to the characteristics of flash memories. In addition, due to the mismatched granularity between read/write and erase operations, a cleaning policy involving garbage collection and wear leveling has to perform data migration incurring high overhead. Another challenge is that...

Creating and editing motion machines for 3D characters

Creator:: Korada, Suman
Abstract:: Recent efforts in user-control of data-driven characters have focused on designing high-level graph data-structures that we call a Behavior Finite State Machine (BFSM). A BFSM is an interactive data-structure that benefits from the advantages of both motion graphs and blend-based techniques for generating animated motion. Each node in a BFSM...

Dual Purpose Utilization of Titanium Alloy Bars for Impressed Current Cathodic Protection and Near Surface Mounted Retrofit in Reinforced Concrete Beams

Creator:: Slawinski, Amanda K.
Abstract:: Many older reinforced concrete bridges and buildings in the United States are considered deficient due to past design codes that are not conservative, increased loading, and deterioration of structural components. Deterioration is most commonly caused by corrosion, which reduces the steel cross sectional area and damages the concrete cross section....
