Accurate-ish
In the highly constructed landscapes of memory in the United States, existing practices of preservation and maintenance of the past are centered on addition and expansion of what has value within the collective public memory, but there is a hesitation that lingers around the notion of …

Accurate and discernible photocollages
There currently exist several techniques for selecting and combining images from a digital image library into a single image so that the result meets certain prespecified visual criteria. Image mosaic methods, first explored by Connors and Trivedi[18], arrange library images according to some …

Accurate Hardware RAID Simulator
… Also a python implementation of this model, Accurate Hardware RAID Simulator (AHRS) is presented and validated against a current hardware RAID controller. It is shown that AHRS can reproduce the behavior of a hardware RAID system with an accuracy of 97.92\% on average compared to a LSI …

Fast and accurate visibility preprocessing
… as well as for algorithms that are more accurate. For most applications these features are not required simultaneously. In this thesis we present two novel visibility preprocessing algorithms, each of which is strongly biased toward one of these requirements.

Fast and Accurate Graph Clustering
… are fast and scalable but significantly less accurate. In this manuscript, we focus on accelerating the performance and improving the scalability of stochastic block partitioning (SBP), a bottom-up (agglomerative) inferential graph-clustering algorithm based on sequential Bayesian inference. …

Accurate Prediction of Chiroptical Properties
Accurate theoretical predictions of optical rotation are of substantial utility to the chemical community enabling the determination of absolute configuration without the need for poten- tially lengthy total synthesis. The requirements for robust calculation of gas-phase optical rotation are well …

Towards Accurate and Fair Deepfake Detection
In this thesis, we tackle two problems in the field of deepfake detection. First, we present a novel approach for the detection of deepfake videos using a pair of vision transformers pre-trained by a self-supervised masked autoencoding setup. Our method consists of two distinct components, one of …

WiFiPoz -- an accurate indoor positioning system
… process and the positioning systems are only as accurate as the offline training phase has been detailed. Moreover, the offline phase must be repeated every time a change in the environment occurs. To avoid these limitations, we focus on improving the accuracy of the indoor positioning system, …

Accurate portfolio risk-return structure modelling
Markowitz's modem portfolio theory has played a vital role in investment portfolio management, which is constantly pushing the development on volatility models. Particularly, the stochastic volatility model which reveals the dynamics of conditional volatility. Financial time series and volatility …

Accurate image reconstruction in radio interferometry
This thesis is concerned with accurate imaging from radio interferometry data and with subsequent analysis so as to determine source positions and fluxes in the radio sky. The thesis makes proposals and implementations of new algorithms, which substantially improve the accuracy of image products …

Accurate characterization of nanophotonic grating structures
Augmented reality waveguides are designed to have grating regions to in-couple, out-couple, and propagate light from a light engine to the user. This thesis develops two reliable systems to qualify manufactured waveguides. The first system determines grating quality by measuring grating pitch and …

Physically accurate collisions in StarLogo Nova
… and games, it may be useful to have physically accurate elastic, inelastic, or partially inelastic collisions. However, StarLogo's current collision detection system relies on detecting overlapping objects after they have already collided, so it cannot simulate such collisions. We create a new …

Accurate frequency estimation with phasor angles
… as soon as it is practical to do so. An accurate measurement of both frequency deviation and rate of change of frequency will greatly facilitate the restoration process. In this thesis, a recursive algorithm for precise frequency and rate of change of frequency measurement is presented. …

Accurate Measurement of Blood Pressure in Pregnancy
… morbidity and mortality in the UK and worldwide. Accurate recording of blood pressure measurement (BPM) is critical to ensure hypertension in pregnancy is correctly diagnosed and managed. Defective equipment and a failure to follow the correct BPM technique can lead to inaccurate readings. Studies …
