Caenorhabditis elegans locomotion is a stereotyped behavior that is ideal for genetic analysis. We integrated video microscopy, image analysis algorithms, and fluid mechanics principles to describe the C. elegans swim gait. Quantification of body shapes and external hydrodynamics and model-based estimates of biomechanics reveal that mutants affecting similar biological processes exhibit related...

Response of the cytoskeleton to mechanical stimulus, which involves coordinated assembly and disassembly of cytoskeletal polymers and their coupling to motor proteins, has been shown to be governed by a ubiquitous mechanical behavior called power-law rheology. Various experimental techniques in cell mechanics have yielded similar qualitative observations and quantitative behavior indicating tha...

OBJECTIVE To determine clinical features and outcome in dogs and cats with obsessive-compulsive disorder (OCD). DESIGN Retrospective study. ANIMALS 103 dogs and 23 cats. PROCEDURES Records of patients with OCD were analyzed for clinical features, medication used, extent of behavior modification, and outcome. RESULTS Most dogs affected with OCD had been obtained from breeders. Male dogs ...

Title of Document: DESIGN OF COMPLIANCE ASSISTED GAITS FOR A QUADRUPEDAL AMPHIBIOUS ROBOT Andrew Richard Vogel, M.S., 2013 Directed By: Professor Satyandra K. Gupta Department of Mechanical Engineering The goal of this thesis was to develop an amphibious legged quadrupedal robot and associated gaits. Gaits of interest included walking, swimming, and smoothly transitioning between the two. Compl...

~ This paper addresses the problem of controlling a manipulator in compliant motion while in contact with an environment having an unknown stiffness. Compliance control is used as an implicit force control scheme and establishes a user-specified target interaction ciyna]nics between the reference position and the contact force. ‘J’wo adaptive lag-plusfccdfor ward compliance compensators are dev...
