Digital electromagnetic calorimeters for future collider applications
The LHC will run until 2040, after which time a new generation of particle colliders is anticipated. To measure the properties of known interactions at the LHC with greater precision, and to probe physics beyond the Standard Model, it is expected that a lepton collider will be constructed. This thesis focuses on the application of digital CMOS MAPS sensors to electromagnetic calorimetry at future colliders.
Simulations of various geometrical configurations of a digital ECAL in the FCC-hh environment, a proposed 100TeV circular proton-proton collider, are presented. The optimal configuration using 50 silicon layers sandwiched between 0.6 thick layers of lead is found to provide an energy resolution of . While this is a slightly poorer standalone resolution than the liquid argon baseline ECAL, this detector technology enables improved combination with information from the inner tracker due to its higher granularity, which may be required to mitigate the high pile-up regime in FCC-hh.
Beam tests of a digital ECAL prototype with 48 ALPIDE sensors (EPICAL-2) are analysed. An event selection algorithm for EPICAL-2 is presented and its merits and performance are evaluated. The response of EPICAL-2 is analysed, and the intrinsic resolution from electron beam tests in the range 1--5~GeV found to be when a simple clustering algorithm is applied. The performance is also modelled in Allpix simulations, and the resolution from simulations found to be .
This is comparable to the CALICE analogue ECAL prototype and a significant improvement upon the resolution of the previous EPICAL-1 prototype. The lateral profiles of EPICAL-2 are presented and the maximum hit density for a 5~GeV electron beam is found to be 300hits/mm. Lastly, the forward-backward asymmetry of EPICAL-2 is examined and its causes identified using simulations
Advanced magnetic suspensions for vibration isolation and fast-attitude control of space-based generic pointing mounts
Advanced magnetic suspension for vibration isolation and fast-attitude control of space-based generic pointing mounts (GPM) is presented in the form of viewgraphs. The following subject areas are covered: design criteria for GPM; GPM system features; GPM performance characteristics; GPM functional block diagram; and other applications for generic magnetic suspension technologies
Learning to Create Jazz Melodies Using Deep Belief Nets
We describe an unsupervised learning technique to facilitate automated creation of jazz melodic improvisation over chord sequences. Specifically we demonstrate training an artificial improvisation algorithm based on unsupervised learning using deep belief nets, a form of probabilistic neural network based on restricted Boltzmann machines. We present a musical encoding scheme and specifics of a learning and creational method. Our approach creates novel jazz licks, albeit not yet in real-time. The present work should be regarded as a feasibility study to determine whether such networks could be used at all. We do not claim superiority of this approach for pragmatically creating jazz
P1_1 The Chief ’s Downfall
In this paper, we calculate an estimate of the Master Chief’s vertical velocity with varying altitude and atmospheric density as he falls towards Earth in the game Halo 3. We plot the velocity over the fall as a function of time and estimate the final velocity to be 69.6ms-1

An idiographic statistical approach to clinical hypothesis testing for routine psychotherapy: A case study.
In order to develop more targeted, efficient, and effective psychotherapeutic interventions, calls have been made in the literature for greater use of idiographic hypothesis testing. Idiographic analyses can provide useful information regarding mechanisms of change within individuals over time during treatment. However, it remains unclear how clinicians might utilize idiographic statistical analyses during routine treatment to test clinical hypotheses, and in turn, guide treatment. We present an idiographic statistical framework for clinical hypothesis testing with routine treatment data that enables clinicians to examine a) whether the client's symptoms and hypothesized mechanisms change over time, b) whether trajectories of change reflect the timing of interventions, c) whether mechanisms predict subsequent symptoms, and d) whether relationships exist between multiple mechanisms, symptoms, or other treatment-related constructs over time. We demonstrate the utility of the approach for clinical hypothesis testing by applying it to routine treatment data collected from a 56 year-old male who presented with a combination of anger problems, anxiety, and depressive symptoms. We discuss how results from analyses can inform the case-formulation and guide clinical decision-making. We aim to make these methods more accessible by providing an online platform where clinicians can enter client data, test their clinical hypotheses using idiographic analyses, and utilize the results to disseminate their findings
Abnormal Ocular Pneumoplethysmographic Results in Unilateral Neovascular Glaucoma.
Little is known about the predictive value of ocular pneumoplethysmography in patients with ophthalmic disease. We evaluated eight patients with unilateral increased intraocular pressure due to neovascular glaucoma who did not have evidence of severe extracranial carotid stenosis by duplex scanning and continuous-wave Doppler ultrasound. The ophthalmic systolic pressure measured by ocular pneumoplethysmography was decreased in the affected eye of all eight patients, indicating that neovascular glaucoma may be a cause of abnormal ocular pneumoplethysmographic results. Patients with neovascular glaucoma tended to have larger interocular ophthalmic systolic pressure differences than other patients with false-positive ocular pneumoplethysmographic results by noninvasive criteria
Research-Based Web Design & Usability Guidelines [2006 edition]
The new edition of the U.S. Department of Health and Human Services’ (HHS) Research-Based Web Design and Usability Guidelines. These guidelines reflect HHS’ commitment to identifying innovative, research-based approaches that result in highly responsive and easy-to-use Web sites for the public.
These guidelines help move us in that direction by providing practical, yet authoritative, guidance on a broad range of Web design and communication issues. Having access to the best available research helps to ensure we make the right decisions the first time around and reduces the possibility of errors and costly mistakes

Implementing The Prison Rape Elimination Act: A Toolkit for Jails
Minor edits. “The goal of this Toolkit is to provide jails of all sizes, political divisions, and geographic locations with a step-by-step guide for preventing, detecting, and eliminating sexual abuse of inmates in their custody – and for responding effectively to abuse when it occurs. Prison rape includes all forms of inmate sexual abuse within a correctional facility, including state and federal prisons, county and municipal jails, police lock-ups, holding facilities, inmate transportation vehicles, juvenile detention facilities, and community corrections facilities. Protecting arrestees, detainees, and inmates from sexual violence is part of a jail’s core mission. This toolkit will help assess your jail’s operations with an eye to improvements.” The Toolkit is divided into folders holding materials related to: introductory information about PREA [Prison Rape Elimination Act] and it Standards; a Self-Assessment Checklist with supporting forms “to provide a step-by-step process for jails to review and assess policies, procedures, and practices in light of the PREA Standards and accepted best practices”; and additional resources to assist you in PREA-readiness
