Breakdown Anodization (BDA) for hierarchical structures of titanium oxide
… method to construct micro-scale and nano-scale structures on titanium surfaces. This method uses environmentally friendly electrolytes, such as nitric acid, and can be fabricated within 30 minutes regardless of substrate size. Because the titanium dioxide is hydrophilic, the micro structured BDA …

Hybrid direct write lithographic strategies for complex hierarchical structures
… a single line or isolated voxel can result in a hierarchical pattern defined by the latent motif of the larger-scale technique. The net result is to shift the burden of high resolution patterning from the direct write to the large scale technique, effectively decoupling the correlation between …

Computational multiscale analysis and optimization of multiphase hierarchical structures within a continuum micromechanics framework
Hierarchical multiphase systems such as plant structures apply the concept of microheterogeneity repetitively across a hierarchy of well-separated length scales: composite microstructures at a smaller scale form the base materials for new microstructures at the next larger scale. Their complex …

The cognition of atonal pitch structures
The Cognition of Atonal Pitch Structures investigated the ability of a listener to internally organize atonal pitch sequences into hierarchical structures. Based on an information processing model proposed by Deutsch and Feroe (1981), the internal organization of well processed pitch sequences will …

New methodologies for multi-scale time-variant reliability analysis of complex lifeline networks
… of analysis as these were relevant for specific structures. Furthermore, chloride-induced deterioration network effects were investigated. Depending on how mathematical models incorporate new information, many approaches are available, such as Bayesian model updating. To make such procedures more …

Helping analysts reason about social network structure: Evidence from training and interactive visualization
… used an interactive program to determine if hierarchical sub-graph hypotheses conformed to network data. To determine what types of training best prepare analysts to interact with such networked data sets, participants were divided into four groups, each completing one of four training …

Development of hierarchical optimal control algorithms for interconnected nonlinear dynamical systems
… is to develop and advance the knowledge of new hierarchical algorithms for optimal control of interconnected nonlinear systems. To achieve this, four basic hierarchical structures are developed by taking into account the manner in which real process measurements taken from interaction inputs are …

Inductive Biases in Learning Hierarchical Abstractions for Bipedal Locomotion
… to the high dimensional state and action space. Hierarchical abstractions and inductive biases emerge as critical components in navigating this complexity, offering pathways for effective learning and adaptation in bipedal locomotion tasks. By leveraging hierarchical structures and inductive …

Fracture characterization of cortical bone at the micrometer and nanometer length scales
… direct product of the interactions between the hierarchical structures that form the building blocks within the material. To fully understand the mechanical properties associated with bone and relate these properties to the scale of the mechanical characterization test, mechanical testing must …

Feminism and the critique of hierarchy: theory and practice
… of the last two decades decried the dominance of hierarchical structures in public and private organizations. This thesis scrutinizes the differences and overlappings of three major feminist "schools" in regard to their advocacy of non-hierarchical forms of organization. The three strands examined …

A comparison of taxonomy generation techniques using bibliometric methods : applied to research strategy formulation
… landscapes through the automatic generation of hierarchical structures (taxonomies) comprised of terms related to a given research field. Several different taxonomy generation algorithms are discussed and analyzed within this paper, each based on the analysis of a data set of bibliometric …

Semantic and data-driven hierarchies for personalized models of affect
When building personalized models of affect, hierarchical structures are important in creating levels of separation and sharing between models. Past studies have indicated that semantic hierarchies along demographic divisions perform well in estimating affect. This work focuses on comparing these …

Power Distribution Network Analysis and Optimization in Digital VLSI Circuits
… and ground buses are broken down into multilevel hierarchical structures. Different algorithms are employed for the analysis at different hierarchies. In all the analyses, input-independent algorithms are used to reduce simulation time and obtain an accurate noise upper bound. Additional …

Scalable manufacturing of hierarchical nanostructures for thermal management
… coatings that have multiple length scales, or hierarchical features. Typically, the formation of hierarchical structures involves multiple steps and/or long processing times. In this new process, the hierarchical geometry is formed in a single step. The starting material-spherical copper …

Assembly and integration of two-dimensional nanomaterials for advanced interfaces and sensors
… In addition, I report on developing flower-like structures (i.e., nanoflowers) of molybdenum disulfide (MoS2) grown by metal-organic chemical vapor deposition (MOCVD), and further demonstrate dual-scale hierarchical structures by introducing additional buckle-delamination induced microscale …

Quantifying collagen-based biological tissues using Fourier-transform-second-harmonic generation imaging
… addition, many biological tissues consist of 3D hierarchical structures made of collagen. Therefore, a 3D quantitative imaging technique with high specificity to collagen fibers will be a valuable tool for diagnostic and medical purposes. Recently, we have generalized FT-SHG to 3D by utilizing …

Boiling on hierarchical nanoengineered surfaces
… have investigated well-ordered, non-scalable structures to study the fundamental limitations of boiling. Here, we developed a highly scalable, three-tier hierarchical surface deposition technique to investigate the pool boiling heat transfer performance with focus on the bubble departure …

Towards abstractive captioning of infographics
… predominantly focused on documents with rigid hierarchical structures and sequentially ordered inputs. These inputs include documents such as news stories, encyclopedia entries, books, and many others. However, little research has focused on understanding text-based information without this …

AN ECOLOGICAL CRITIQUE TO DIGITAL BUSINESS ECOSYSTEMS THROUGH THE CASE OF ESPORTS
… where complementarity, interdependence, and non-hierarchical structures define the interactions among networked organisational entities. Nonetheless, recent critiques have pointed out that many of these applications maintain an ecosystemic viewpoint only at a superficial level, failing to …

Exploring the relationships between dialogue and inclusive school communities
… case study examined the journey from exclusive, hierarchical structures to inclusive, democratic schools. In particular, the study examined the relationship between dialogue and inclusive leadership practices from three principals’ perspectives, including their conception of an inclusive school, …
