Complex Equilibrium of Laterally Curved Wakes
… there has been little research being done on laterally curved wakes. Single and two-point velocity measurements were taken on a plane and laterally curved turbulent wakes to understand the evolution and effect of lateral curvature into the far wake region. The analyses provide useful …

Development of an Automotive Ground Vehicle Platform for Autonomous Urban Operations
… using a map-linearized PI controller and lateral curvature control using a bicycle model. The control algorithms proved capable of controlling the vehicle at a level acceptable for autonomous operations. Communications are implemented using the Joint Architecture for Unmanned Systems …

Contributions to the Understanding of Turbulent Boundary Layers Over Curved Walls
… the concurrent pressure gradient and wall curvature effects, which are commonplace in engineering. Three particle image velocimetry (PIV) configurations were employed to measure the boundary layer in detail: one spanned the entire afterbody, another had narrow strips sampled at 16 kHz, and …

A comprehensive analysis of long bone curvature in Neanderthals and modern humans using 3D morphometrics
… as having a marked degree of anteroposterior curvature of the femoral shaft. Although initially believed to be pathological, subsequent discoveries of Neanderthal remains made femoral curvature as well as the lateral curvature of the radius to be considered derived Neanderthal features. …

Genomic Analysis of Human Spinal Deformity and Characterization of a Zebrafish Disease Model
<p>Scoliosis is characterized by a lateral curvature of the spine that requires long-term bracing and invasive spinal surgery in cases with progressive deformity. Some individuals develop scoliosis secondary to congenital malformations or syndromic disorders, but most scoliosis is considered …

Investigating the Biological Mechanisms Underlying Axis Morphogenesis Using a Novel Zebrafish Model of Idiopathic-like Scoliosis
Scoliosis is characterized by an abnormal lateral curvature and three-dimensional rotation of the spine and adolescent idiopathic scoliosis (AIS), which has no known cause, affects about 4% of children worldwide. As a result of the complex genetic landscape of AIS as well as the historical lack of …

The Space-time Structure of an Axisymmetric Turbulent Boundary Layer Ingested by a Rotor
… ingestion noise. The combined effect of lateral curvature and streamwise pressure gradient are examined on the mean flow, turbulence structure, velocity correlations and wall pressure fluctuations. Additionally, the upstream influence of a rotor operating in this flow is examined to …

Dynamic surface topography and its application to the evaluation of adolescent idiopathic scoliosis
… idiopathic scoliosis patients. Scoliosis or curvature of the spine is one of the major skeletal diseases in adolescents where in the majority of cases the cause is unknown or idiopathic. The progression of the disease occurs in three dimensions with the spine simultaneously curving towards …
