Sampling And Reliability In Class Action Litigation, Hillel J. Bavli

Faculty Journal Articles and Book Chapters

It is often argued that the use of sampling to prove classwide liability and damages in class action litigation serves purposes of efficiency, but only at the cost of reliability. Concern for reliability is central to the permissibility of such methodologies. This article explains certain conclusions regarding sampling and reliability — and, particularly, that sampling may improve the reliability of legal outcomes — and discusses these conclusions in light of the Supreme Court’s recent decision in Tyson Foods, Inc. v. Bouaphakeo.

Copyright In Pantomime, Brian L. Frye

Cardozo Arts & Entertainment Law Journal

Why does the Copyright Act specifically provide for the protection of "pantomimes"? This Article shows that the Copyright Act of 1976 amended the subject matter of copyright to include pantomimes simply in order to conform it to the Berne Convention for the Protection of Literary and Artistic Works. It further shows that the Berlin Act of 1909 amended the Berne Convention to provide for copyright protection of "les pantomimes" and "entertainments in dumb show" in order to ensure copyright protection of silent motion pictures. Unfortunately, the original purpose of providing copyright protection to '"pantomimes " was forgotten. This Article argues …

Individual And Population-Level Responses To Ocean Acidification, Ben P. Harvey, Niall J. Mckeown, Samuel P. Rastrick, Camilla Bertolini, Andy Foggo, Helen Graham, Jason M. Hall-Spencer, Marco Milazzo, Paul W. Shaw, Daniel P. Small, Philippa J. Moore

Research outputs 2014 to 2021

Ocean acidification is predicted to have detrimental effects on many marine organisms and ecological processes. Despite growing evidence for direct impacts on specific species, few studies have simultaneously considered the effects of ocean acidification on individuals (e.g. consequences for energy budgets and resource partitioning) and population level demographic processes. Here we show that ocean acidification increases energetic demands on gastropods resulting in altered energy allocation, i.e. reduced shell size but increased body mass. When scaled up to the population level, long-term exposure to ocean acidification altered population demography, with evidence of a reduction in the proportion of females in the …

Phase Transformation And Deformation Behavior Of Niti-Nb Eutectic Joined Niti Wires, Liqiang Wang, Cong Wang, Laichang Zhang, Liangyu Chen, Weijie Lu, Di Zhang

Research outputs 2014 to 2021

NiTi wires were brazed together via eutectic reaction between NiTi and Nb powder deposited at the wire contact region. Phase transformation and deformation behavior of the NiTi-Nb eutectic microstructure were investigated using transmission electron microscopy (TEM) and cyclic loading-unloading tests. Results show that R phase and B19′ martensite transformation are induced by plastic deformation. R phase transformation, which significantly contributes to superelasticity, preferentially occurs at the interfaces between NiTi and eutectic region. Round-shaped Nb-rich phase with rod-like and lamellar-type eutectics are observed in eutectic regions. These phases appear to affect the deformation behavior of the brazed NiTi-Nb region via five …

Developing Equations For Estimating Reference Evapotranspiration In Australia, Matin Ahooghalandari, Mehdi Khiadani, Mina Esmi Jahromi

Research outputs 2014 to 2021

Quantifying reference evapotranspiration (ET₀) is essential in water resources management. Although, many methods have been developed with different level of accuracy, in this study, two new equations were developed and optimized for estimating ET₀ using Honey-Bee Mating Optimization (HBMO) algorithm. The firs eq. estimates ET₀ from extraterrestrial radiation (R_a), relative humidity (RH) and mean daily temperature (T_mean), while the second uses the same parameters except that mean daily temperatures is replaced with maximum daily air temperature (T_max). Both equations were developed using climatic data from eight weather stations in Western …

The Stability Of Old Skills During Transfer, Craig P. Speelman, John D. Forbes, Kris Giesen, Matthew Parkinson, Lois Johnson

Research outputs 2014 to 2021

This research was designed to evaluate the extent to which power functions can predict performance on a task when performance context has been altered. Since power functions reliably describe performance improvements during practice, an assumption implicit in some theories of skill acquisition and transfer is that transfer performance will continue to improve as an extrapolation of the practice power function. In the training phase of Experiment 1, 120 participants practiced solving simple problems from the six-times table. In the transfer phase, these same problems were presented again, intermixed with problems from one of the six conditions differing in various respects …

New Cost Model For Feasibility Analysis Of Utilising Special Purpose Machine Tools, Ana Vafadar, Majid Tolouei-Rad, Kevin Haywood

Research outputs 2014 to 2021

Special purpose machine tools (SPMs) have been widely used to perform drilling-related operations in high volume production including within automotive component industries. The first step in designing and manufacturing a SPM is a feasibility analysis. Since SPMs have relatively higher investment cost than other machine tools, this task must be performed before any investment on the preparation of detailed design. The present paper explores an economic feasibility analysis strategy which aims to make logical decision by assessing the strengths and limitations of an SPM in comparison with other machine tools. The mathematical product cost model for SPMs is proposed for …

An Automated Approach For Digital Forensic Analysis Of Heterogeneous Big Data, Hussam Mohammed, Nathan Clarke, Fudong Li

Research outputs 2014 to 2021

The major challenges with big data examination and analysis are volume, complex interdependence across content, and heterogeneity. The examination and analysis phases are considered essential to a digital forensics process. However, traditional techniques for the forensic investigation use one or more forensic tools to examine and analyse each resource. In addition, when multiple resources are included in one case, there is an inability to cross-correlate findings which often leads to inefficiencies in processing and identifying evidence. Furthermore, most current forensics tools cannot cope with large volumes of data. This paper develops a novel framework for digital forensic analysis of heterogeneous …

Structural Geodesic-Tchebychev Transform: An Image Similarity Measure For Face Recognition, Ali Nadhim Razzaq, Zahir Hussain, Hind Rustum Mohammed

Research outputs 2014 to 2021

This work presents a new holistic measure for face recognition. Face recognition involves three steps: Face Detection, Feature Extraction and Matching. In the face detection process to identify the face area in face images, Viola-Jones algorithm has been used. Feature extraction is based on performing double-transformation, where discrete Tchebychev transform is performed on the geodesic distance transform of the grayscale image. Structural Similarity (SSIM) is applied to the resulting image double-transform to find matching factor with other image faces in the FEI (Brazilian) database. Performance is measured using a confidence criterion based on the similarity distance between the recognized person …

The Possibilities Of A Line: Marking The Glissando In Music, Cat Hope, Michael Terren

Research outputs 2014 to 2021

The glissando as it is deployed in Western art music notation carries with it a number of challenges to the hegemony of traditional harmony, rhythm, and notation. The glissando embodies the smooth line, unlike the striated pitch-time space of traditional Western music, which aligns the glissando to many philosophical concepts, as well as mathematical, scientific, and architectural disciplines. Select works by Iannis Xenakis, James Tenney and Giacinto Scelsi are discussed for their development of glissandi as integral formal components, especially around the glissando’s tendency to encourage stasis. Compositional attempts to combine the nature of glissandi with drone in the author’s …

Unsynchronized Scanning With A Low-Cost Laser Range Finder For Real-Time Range Imaging, Isa Hatipoglu

All ETDs from UAB

Range imaging plays an essential role in many fields: 3D modeling, robotics, heritage, agriculture, forestry, reverse engineering. One of the most popular range-measuring technologies is laser scanner due to its several advantages: longer range, highly precise and real-time measurement capabilities, no lighting condition dependency, and less computational power requirement. However, laser scanners are very costly. Their high cost limit their usage in applications with low-cost limitation, especially for static environments like heritage sites. In this work, we present an unsynchronized scanning with a low-cost laser range finders (LRFs) to decrease scanning period and reduce vibrations caused by “scan-stop” in synchronized …

Laboratory-Scale Investigations Of Low-Permeability Porous Media By Analysis Of Transient Pressure Measurements, Michael Joseph Hannon

All ETDs from UAB

To provide a greater understanding of critical parameters of ultra-tight geologic formations such as shales, this report considers alternative approaches to the laboratory-scale pressure-pulse-decay permeametry method. These include new analytical models with which to analyze data from the principal rapid pulse-decay variants used in professional laboratories today. Novel revisions to the pulse-decay method are suggested and compared, in theory, against existing technologies. A new experimental procedure for the assessment of whole-core cylindrical samples is proposed that simultaneously determines the porosity and apparent permeabilities parallel and perpendicular to the native bedding plane from a single test on a single cylindrical core …
