Modular Dynamic Modeling and Development of Micro Autonomous Underwater Vehicle: Lancelet
… model of AUV suitable for modular parameter estimation and dynamic modeling is established. The empirical methods for the hydrodynamic coefficients and added mass estimation are summarized, and the relationship between hydrodynamic coefficients and hydrodynamic derivatives is derived. A …

Application of Optical CT to Estimate the Mass of Macroalgae in a Tank of Water
This thesis develops and tests a mass estimation system for macroalgae using optical computed tomography. The system consists of a table with a fixed camera and backlighting, which rotates around a container of macroalgae to collect images from various points. The images capture the translucency …

Evolution of the Stellar Mass Density of Galaxies Since Redshift 1.0
At variance to other methods of mass estimation of galaxies, stellar masses can be estimated also at higher redshifts and therefore with reduced angular resolutions, when observing with ground based instruments. For a sample of 25000 galaxies drawn from the COMBO-17 survey stellar masses are …

A Community-Scale Perspective on the Diversification of Tetrapod Ecology and Botanical Turnover based on the Pennsylvanian of the Maritimes Basin, Atlantic Canada
… a case study. For this dissertation, I use body mass and diet as the variables through which I study tetrapod functional diversity. In the course of this investigation, I ask three foundational questions about community structure developments through the Lower-Middle Pennsylvanian of the …

A quantitative genetic approach to study the ontogeny and evolution of ecogeographic patterns in the human limb skeleton
… whether allometric relationships between body mass and skeletal traits are conserved among different groups and across different age stages. Using a contemporary Taiwanese sample, I evaluated body mass estimation equations for children and juvenile individuals developed using a European …

The Development of a Locomotion Interface for Virtual Reality Terrain Simulation
… The document presents a CoM (center-of-mass) estimation algorithm that is based on LIP (linear inverted pendulum) model and ZMP (zero-moment point). And the estimation method is further validated through two applications: an initial framework of tele-locomotion and VR interaction. In the …

ADAPTIVE CONTROL DESIGN FOR QUADROTORS
… is considered with an adaptive component for the estimation of the uncertain mass of the quadrotor. For the rotational subsystem in the inner loop a backstepping based control design is adopted due to its systematic design and intuitive approach. An adaptive component is further integrated with it …

Development of hay yield monitoring systems
… using proximal and remote sensing for hay yield estimation has shown promise but faces several limitations. These include low accuracy in mixed species or low-density crops and in heterogeneous field conditions. Challenges also arise in selecting optimal data collection dates and dealing with …

Hydrodynamic added mass determination and attitude estimation of the Seahog - a remotely-operated underwater vehicle
… and magnetometer, the optimal attitude estimation of the Seahog required sensor fusion. The Seahog’s Inertial Measurement Unit (IMU) is a 9 degree of freedom (DOF) unit fitted with an embedded processor collectively referred to as the iNEMO. Due to the time-variant nature of the magnetic …

Efficiently Searching for Objects Within Large Collections of Images and Video
… new species in an expedition, known as missing mass estimation. ExSample adapts related ideas to improve sampling from videos in an online setting. Beyond their common application goal of helping users with image and video searches, both SeeSaw and ExSample also share some design goals: 1. …

Development of a Heavy Truck Vehicle Dynamics Model using Trucksim and Model Based Design of ABS and ESC Controllers in Simulink
… CG combination were utilized for this purpose. A mass estimation algorithm was developed which estimates the mass of the combination vehicle using the data which would normally be present on the CAN bus of an actual vehicle such as the engine torque, transmission gear status and vehicle speed. The …
