Examining the Relationship Between Students' Measurement Schemes for Fractions and Their Quantifications of Angularity
In the basic understanding of measurement, students are expected to be able to subdivide a given whole into a unit and then change the position of that unit along the entire length of the whole. These basic operations of subdivision and change of position are related to the more formal operations …

Sensing for Electromechanical Systems
… In this work, custom instrumentation and measurement schemes are introduced and applied to non-contact voltage measurement, the integrated electronic piezo-electric (IEPE) standard, and cutting tool condition monitoring.

Hashing hardware : identifying hardware during boot-time system verification
… the machine starts in a trusted state. Such measurements, however, do not include any information about the underlying hardware of the machine. Recent DRAM-based attacks and the growing complexity of the supply chain attest to the importance of measuring hardware at boot. In this thesis, we …

The Violation of Bell's Inequality in a Deterministic but Nonlocal Model
… of Bell's Inequality through the use of nonlocal measurement schemes as encapsulated in a quasi-deterministic toy model. This toy model, called the Q Box, is reminiscent of Mermin's Box in that it describes a system that appears to be deterministic yet produces the statistics of a quantum type …

Efficient data collection strategies for rapid learning in physical environments
… allowing efficient scene inference under various measurement schemes and budget constraints. We introduce a novel nonlinear radar modality and discuss efficient design techniques for this setting. Finally, we introduce a novel methodology for optical imaging of non line of sight hidden scenes by …

Tuning Spin Currents with Ultrathin Heavy Metal Microstructure
… in common electrical spin injection / detection schemes. We probe spin reflection, transmission and accumulation at the HM|FM interface in three such measurement schemes with a systematic set of spin Hall magnetoresistance (SHMR), spin pumping and spin-orbit torque (SOT) effective field …

Condition assessment of GFRP-retrofitted concrete cylinders using electromagnetic waves
… cylinders through the use of far-field radar measurements (electromagnetic or EM waves). In this development, two far-field monostatic ISAR (inverse synthetic aperture radar) measurement schemes are identified for collecting radar measurements, and the backprojection algorithm is applied for …

The Measurement Problem within Quantum Mechanics on a Non-commutative Plane
This work addresses the measurement problem in quantum physics through the framework of quantum mechanics on a non-commutative plane. The study is motivated by the conceptual tension between unitary quantum evolution and the non-unitary collapse postulate, and by the incompatibility between general …

Evaluating Streambank Retreat Prediction Using the BANCS Model in the Valley and Ridge Physiographic Province
… to determine the impact of different erosion measurement schemes on bank erosion estimates and BANCS curves, and alternate NBS methods that capture flow energy beyond bankfull were applied. Three years of monthly erosion data on 64 streambanks were used to assess the spatial and temporal …

Random observations on random observations: Sparse signal acquisition and processing
… set of more general, often randomized, linear measurements. If properly chosen, the number of measurements can be much smaller than the number of Nyquist-rate samples. A common theme in this research is the use of randomness in signal acquisition, inspiring the design of hardware systems that …

A three dimensional surface measurement and reconstruction system for respiratory function analysis
… not well suited in application for spirometric measurement for ambulatory monitoring. A sensor matrix measurement technique is investigated to identify suitable sensing elements with which to base an upper body surface measurement device that monitors respiration. This thesis is divided into two …

Spatial Coupling for High-Dimensional Estimation
… problems allow flexibility in the way in which measurements are acquired. For example, in compressed sensing MRI, the sampling frequencies can be chosen to optimize reconstruction performance. This thesis investi- gates spatial coupling, a design technique that can enhance reconstruction …

Hydrodynamic and ballistic transport in high-mobility GaAs/AlGaAs heterostructures
… (4.1 K to 40 K) zero-field nonlocal resistance measurements at various locations in the device to map the movement of electrons. The experiments, along with interpretation using kinetic simulations, demarcate hydrodynamic and ballistic regimes and establish the dominant role of electron-electron …
