Design, analysis and passive balance control of a 7-DOF biped robot
(2007)
Biped robots have many advantages than traditional wheeled or tracked robots. They have better mobility in rough terrain and can travel on discontinuous path. The legs can also provide an active suspension that decouples ...
Introduction to the legacy forest small streams study : runoff patterns and related biogeochemistry on the western portion of the boreal shield
(2007)
The Forest Watershed and Riparian Disturbance (FORWARD) Project is an ongoing study initiated on the western Boreal Plain (northwestern Alberta) in 2001 to incorporate hydrologic processes into industrial forest management. ...
Cognitive appraisals, symptom severity, and obtained treatment during the perimenopause : a retrospective study
(2007)
Menopause is a prevalent concern for women ranging from the ages of 40 to 60, as it is often associated with significant amounts of physical and emotional distress. Previous research has shown an association between women's ...
Psychological responses to three dimensional body shape exposure in female university students
(2007)
The purpose of the present study was to experimentally investigate the psychological responses of women to two dimensional (2D) or three-dimensional (3D) body image exposure. Seventy female undergraduate students were ...
Stand structure differences resulting from post-harvest silviculture in boreal mixedwoods
(2007)
Under the Ontario Forest Accord, several parcels of land have recently been designated as protected areas reducing the area available for forest management. As a result, forestry companies will likely have to intensify ...
Nonlinear dynamics of railway wheelsets incorporating randomness
(2007)
The thesis is to investigate the dynamic behavior of a single-axle railway wheelset and identify its chaotic behavior by means of time history, phase portrait, Lyapunov exponents, information dimension, bifurcation diagram ...
Effect of water salinity on the hydro-mechanical behaviour of light backfill material
(2007)
A series of one-dimensional compression tests was conducted to examine and compare the hydro-mechanical behaviour of light backfill (LBF) material, composed of 50% bentonite and 50% sand, in the presence of distilled water ...
On-line estimation of first order plus dead time process parameters based on under or over-parameterized models
(2007)
Simple on-line process identification methods that can be used in tuning PID controllers or any other controllers have been studied in this work. The underlying continuous-time first order plus dead time FOPDT process model ...
Integrated mechanisms for QoS and restoration in mesh transport networks
(2007)
Survivable networks have the capability to survive from the events of network components failures. The resilience mechanisms in these networks protect and restore the impaired communication paths by using spare capacity. ...
Pulsatile flow interaction with a stented artery : compliance mismatch effects
(2007)
Atherosclerosis is a group of diseases characterized by thickening of the arterial wall resulting in a reduction in the cross-sectional area of the lumen. One of treatments for these artery diseases is stent angioplasty. ...
