Privacy vs. Technology: What privacy rights do we have and how can we protect these rights?
… privacy interests of personal data and personal unobservability and how these might be affected by technology. Chapter Four focuses on personal data and argues that, under certain conditions, we should recognise a right to personal data otherwise our fundamental interests will be set back. …

Near aggregation: a time and frequency domain analysis using state trajectories and transfer function residues
… that near-aggregation is equivalent to near-unobservability (roughly, an invariant subspace close to the null space of C). Here we establish a relationship between near-unobservability and modal measures of observability as suggested by Selective Modal Analysis. With this result we then …

Economic Measurement of Consumers and Firms: A Model Consistent Approach
… This thesis exploits the similarity between the unobservability of utility and the unobservability of â outputâ in a multi-output setting. Duality theory provides the desired rigour of economic science. The quality of its operationalisation is dependent upon the art of modelling. An appropriate …

Essays on dynamic public policy.
… resources, and (3) the realized returns. The unobservability of returns creates a novel motive for subsidizing agents who have ideas but lack resources to invest in them. The unobservability of initial types and actions implies that the subsidy that poor agents with ideas receive is limited by …

Estimation and tracking of rapidly time-varying broadband acoustic communication channels
… due to channel structure, reflected as parameter unobservability in EKF and insufficient excitation in EM. Modifications of both algorithms, including a two-model based EKF and a subspace EM algorithm which selectively track dominant taps and reduce prediction error, are proposed to overcome the …

State Estimation and Voltage Security Monitoring Using Synchronized Phasor Measurements
… of the unknown voltages. The concept of depth of unobservability is introduced. It is a general measure of the physical distance of unobserved buses from those known. The effects of depth of unobservability on the number of PMU placements and the errors in the estimation of unobserved buses will …

Precision control of continuous microcontact printing
… system, including uncontrollability and unobservability, were quickly identified. Maximum potential control performance under these constraints was explored and demonstrated experimentally, and it was shown that the inherent limitations made satisfactory closed-loop performance …

The Distance to Uncontrollability via Linear Matrix Inequalities
The distance to uncontrollability of a controllable linear system is a measure of the degree of perturbation a system can undergo and remain controllable. The definition of the distance to uncontrollability leads to a non-convex optimization problem in two variables. In 2000 Gu proposed the first …

A Practical Comprehensive Approach to PMU Placement for Full Observability
In recent years, the placement of phasor measurement units (PMUs) in electric transmission systems has gained much attention. Engineers and mathematicians have developed a variety of algorithms to determine the best locations for PMU installation. But often these placement algorithms are not …
