Evolution of Axial Skeleton Diversity across Reptilia
The axial skeleton is a key diagnostic character of vertebrate animals. Comprising the vertebral column and ribs, the axial skeleton is a support structure from which all appendages of the vertebrate body are suspended. Reptilia is a hugely diverse clade of vertebrates, with regards to body form, …

The effects of stroke on the skeleton
Stroke is now a well-recognised risk factor for hip fracture. The aim of this study was to elucidate the pathophysiological mechanisms by which hip bone loss occurs in hemiplegia and to test the efficacy of a novel pharmaceutical strategy for preserving bone in stroke patients. Patients who were …

Matrix probing, skeleton decompositions, and sparse Fourier transform
… inverting elliptic operators in variable media. Skeleton decompositions in sublinear time A skeleton decomposition of a matrix A is any factorization of the form A:CZAR: where A:C comprises columns of A, and AR: comprises rows of A. In this paper, we investigate the conditions under which random …

Hybrid architecture for human action recognition using skeleton data
… comparable to the state-of-the-art methods in skeleton based multi-person, multiview human action recognition. By leveraging attention-based GCN, the model captures context-dependent intrinsic topology while enhancing discriminative information. Furthermore, utilizing transformers, we harness …

Ontogeny and evolutionary morphology of the skeleton in frogs
Ontogenetic studies, or studies of development, have repeatedly proven insightful in exploring questions of morphological evolution. Here, two projects illuminate the relationship between ontogeny and the evolution of skeletal morphology in frogs. In the first part of this dissertation, I examine …

Sketch-based skeleton-driven 2D animation and motion capture.
… the development of a set of novel sketch-based skeleton-driven 2D animation techniques, which allow the user to produce realistic 2D character animation efficiently. The technique consists of three parts: sketch-based skeleton-driven 2D animation production, 2D motion capture and a cartoon …

3-D reconstruction of the human skeleton during motion
L’analisi del movimento umano ha come obiettivo la descrizione del movimento assoluto e relativo dei segmenti ossei del soggetto e, ove richiesto, dei relativi tessuti molli durante l’esecuzione di esercizi fisici. La bioingegneria mette a disposizione dell’analisi del movimento gli strumenti ed i …

Microcomputer-assisted diagnosis of inherited disorders of the skeleton
Several hundred inherited disorders of the skeleton have been delineated. Individually these conditions are rare, but as a group they cause much crippling and hardship. Several factors, including the rarity and complexity of the manifestations of these conditions, as well as semantic overlap, …

Non-lysosomal protein degrading systems in chicken skeleton muscle
In an attempt to understand the roles played by the ubiquitin-dependent and calpain pathways in protein degradation in chicken skeletal muscles, biochemical studies were conducted on components of these two systems as well as their potential endogenous and exogenous substrates. ATP- and ubiquity …

Transient liquid-phase infiltration of a powder-metal skeleton
… is a new method for densifying a powder-metal skeleton that produces a final part of homogeneous composition without significant dimensional change, unlike traditional infiltration and full-density sintering. Fabrication of direct metal parts with complex geometry is possible using TLI in …

THE NON-ERYTHROID MEMBRANE SKELETON AND ITS ROLE IN MECHANOTRANSDUCTION
… is thereby on the role of the spectrin membrane skeleton in transducing forces to and from non-erythroid mammalian cells. This spectrin based membrane skeleton has been the focus of much study in the context of red blood cells, as it determines their mechanical properties due to the lack of an …

Kinematics of the equine axial skeleton during aqua-treadmill exercise
Equine aqua-treadmills are increasingly applied within the industry for rehabilitation from injury and training. Research into aqua-treadmill exercise has been increasing yet there are still opportunities to further quantify the effect of water depth on locomotion in order to optimise …

Interactions Between Aging and Chronic Kidney Disease on the Skeleton
In the US, 15% of adults have chronic kidney disease (CKD). While CKD occurs across all ages, the prevalence is highest in the aged, with ~40% of individuals over age 65 having some form of CKD. CKD and aging are each independently associated with higher fracture risk, and thus overlaying CKD in …

Studies towards the synthesis of the guaianolide and pseudoguaianolide skeleton
A synthesis of the guaiane skeleton is presented in my thesis. Guaianolides and pseudoguaianolides are sesquiterpene lactones and share a sommon backbone: the guaiane skeleton. Hundreds of natural products belong to these families of compounds. The guaiane skeleton is characterised by a …

Structured meshes: composition and remeshing guided by the Curve-Skeleton
… which starts from a triangle mesh and the curve-skeleton of the shape. The second approach allows to build complex shapes by procedural composition of PAM's. Since both quad layouts and PAMs exploit their global struc- ture, similarities between the two will be discussed, especially how their …

Autonomous active ankle exo-skeleton devices provide metabolic cost reduction
… with the usage of an autonomous active ankle exoskeleton. The primary method to identify the associated metabolic costs was through the comparison of cardiovascular and respiratory activity during gait with and without the use of the exoskeleton. Rates of oxygen consumption, carbon dioxide …

Design and Implementation of the Kinect Controlled Electro-Mechanical Skeleton (K.C.E.M.S)
… feasibility and design behind a simple robotic skeleton that utilizes the Kinect to mimic human movements in near real-time. The goal of this project is to construct a 1/3-scale model of a robotically enhanced skeleton and demonstrate the abilities of the Kinect as a tool for human movement …
