Impact of ungulate exclusion on understorey succession in relation to forest management in the Intermountain Western United States

Creator:: Pekin, Burak K., Endress, Bryan A., Wisdom, Michael J., Naylor, Bridgett J., and Parks, Catherine G.
Abstract:: QUESTIONS: Do successional trajectories in plant diversity, heterogeneity and dominance respond differently to ungulate exclusion in unmanaged forests vs managed forests that are thinned and burned? Is vegetation in recently thinned and burned stands more sensitive to changes in the grazing regime? LOCATION: Northeast OR, USA. METHODS: We evaluated changes...

Creator:: Pekin, Burak K., Wisdom, Michael J., Parks, Catherine G., Endress, Bryan A., and Naylor, Bridgett J.
Abstract:: Questions: Are exotic plant species favoured by non-native ungulate herbivores and disadvantaged by native herbivores in forested rangelands? Do the impacts of ungulates on exotic vs native plants depend on forest management activities such as prescribed fire and stand thinning? Location: Northeastern Oregon, USA. Methods: We recorded changes in richness...

Ungulate Browsing Maintains Shrub Diversity in the Absence of Episodic Disturbance in Seasonally-Arid Conifer Forest

Creator:: Pekin, Burak K., Wisdom, Michael J., Endress, Bryan A., Naylor, Bridgett J., and Parks, Catherine G.
Abstract:: Ungulates exert a strong influence on the composition and diversity of vegetation communities. However, little is known about how ungulate browsing pressure interacts with episodic disturbances such as fire and stand thinning. We assessed shrub responses to variable browsing pressure by cattle and elk in fuels treated (mechanical removal of...

Active and Passive Structural Vibration Mitigation for High-Speed Machine Tools

Creator:: Indrarto, Christopher Wilfred
Abstract:: This thesis presents novel feedback and feedforward control system design strategies for active to passive vibration mitigation of residual vibrations on high speed machine tools. Residual vibrations on high-speed machine tools are triggered when the machine axes (table) undergo large accelerations, which induce sudden inertial forces and excite the lightly...

Smooth Trajectory Generation for Machine Tools and Industrial Robots

Creator:: Tajima, Shingo
Abstract:: This thesis presents accurate and time-optimal smooth reference trajectory generation techniques for manufacturing equipment such as high-speed machine tools (MT) and industrial robots (IR). Typical machining tool-paths for MTs and IRs are defined as a series of discrete linear moves. Although Point-to-Point (P2P) feed motion can be generated by interpolating...

Optimal High-bandwidth Non-collocated Control of Ball-screw Drives

Creator:: Dumanli, Alper
Abstract:: This work presents a novel optimal control strategy for precision motion control of flexible ball-screw feed drives. Typically, ball-screw feed drive control relies on state feedback taken both from motor and the load sides. The controller designed in this thesis is based on the non-collocated framework, where all the feedback...

Active and Passive Control of Machine Tool Vibrations for High Speed and Accuracy

Creator:: Dumanli, Ahmet Alper
Abstract:: High-performance mechatronic systems are widely used in precision manufacturing equipment such as CNC machine tools, 3D-Printers, photolithography systems, industrial robots, and Coordinate Measuring Machines (CMMs). These equipment are utilized in producing parts and components for aviation, semiconductor, optics, and many other emerging industries, with geometric features and surface properties within...

Mechanics and Dynamics of Low Frequency Vibration Assisted Machining

Creator:: Eren, Bora
Abstract:: This thesis presents mechanics and dynamics of Low Frequency Vibration Assisted Turning (LFV-T). First, a mechanistic model for analytical cutting force and specific cutting energy prediction is presented. Kinematics of the process is used to analyze the cut surface topography and derive the uncut chip thickness variation for various modulation...
