Artificial Intelligence & Machine Learning: A Model For A New Judicial System?, Paula C. Arias

Articles

Artificial Intelligence and Machine Learning are a result not only of technological advances but also of the exploitation of information or data, which has led to its expansion into almost all aspects of modern life, including law and its practice. Due to the benefits of these technologies, such as efficiency, objectivity, and transparency, the trend is towards the integration of Artificial Intelligence and Machine Learning in the judicial system. Integration that is advocated at all levels and, today, has been achieved mostly under the implementation of tools to assist the exercise of the judiciary. The «success» of this integration has …

Higher Order Correlations In A Levitated Nanoparticle Phonon Laser, Kewen Xiao, Robert M. Pettit, Wenchao Ge, Long H. Nguyen, Siamak Dadras, A. Nick Vamivakas, Mishkatul Bhattacharya

Articles

We present theoretical and experimental investigations of higher order correlations of mechanical motion in the recently demonstrated optical tweezer phonon laser, consisting of a silica nanosphere trapped in vacuum by a tightly focused optical beam [R. M. Pettit et al., Nature Photonics 13, 402 (2019)]. The nanoparticle phonon number probability distribution is modeled with the master equation formalism in order to study its evolution across the lasing threshold. Up to fourth-order equal-time correlation functions are then derived from the probability distribution. Subsequently, the master equation is transformed into a nonlinear quantum Langevin equation for the trapped particle’s position. This equation …

Beyond Reasonable Doubt: A Proposal For Undecidedness Blocking In Abstract Argumentation, Pierpaolo Dondio, Luca Longo

Articles

In Dung’s abstract semantics, the label undecided is always propagated from the attacker to the attacked argument, unless the latter is also attacked by an accepted argument. In this work we propose undecidedness blocking abstract argumentation semantics where the undecided label is confined to the strong connected component where it was generated and it is not propagated to the other parts of the argumentation graph. We show how undecidedness blocking is a fundamental reasoning pattern absent in abstract argumentation but present in similar fashion in the ambiguity blocking semantics of Defeasible logic, in the beyond reasonable doubt legal principle or …

Long Term Predictions Of Coal Fired Power Plant Data Using Evolved Recurrent Neural Networks, Travis Desell, Abdelrahman Elsaid, Zimeng Lyu, David Stadem, Shuchita Patwardhan, Steve Benson

Articles

This work presents an investigation into the ability of recurrent neural networks (RNNs) to provide long term predictions of time series data generated by coal fired power plants. While there are numerous studies which have used artificial neural networks (ANNs) to predict coal plant parameters, to the authors’ knowledge these have almost entirely been restricted to predicting values at the next time step, and not farther into the future. Using a novel neuro-evolution strategy called Evolutionary eXploration of Augmenting Memory Models (EXAMM), we evolved RNNs with advanced memory cells to predict per-minute plant parameters and per-hour boiler parameters up to …

Smart Routing: Towards Proactive Fault Handling Of Software-Defined Networks, Ali Malik, Benjamin Aziz, Mo Adda, Chih-Heng Ke

Articles

In recent years, the emerging paradigm of software-defined networking has become a hot and thriving topic in both the industrial and academic sectors. Software-defined networking offers numerous benefits against legacy networking systems by simplifying the process of network management through reducing the cost of network configurations. Currently, data plane fault management is limited to two mechanisms: proactive and reactive. These fault management and recovery techniques are activated only after a failure occurrence and hence packet loss is highly likely to occur. This is due to convergence time where new network paths will need to be allocated in order to …

In Their Shoes: A Structured Analysis Of Job Demands, Resources, Work Experiences, And Platform Commitment Of Crowdworkers In China, Yihong Wang, Konstantinos Papangelis, Ioanna Lykourentzou, Hai-Ning Liang, Irwyn Sadien, Evangelia Demerouti, Vassilis-Javed Khan

Articles

Despite the growing interest in crowdsourcing, this new labor model has recently received severe criticism. The most important point of this criticism is that crowdworkers are often underpaid and overworked. This severely affects job satisfaction and productivity. Although there is a growing body of evidence exploring the work experiences of crowdworkers in various countries, there have been a very limited number of studies to the best of our knowledge exploring the work experiences of Chinese crowdworkers. In this paper we aim to address this gap. Based on a framework of well-established approaches, namely the Job Demands-Resources model, the Work Design …

Delivering Gender Justice In Academia Through Gender Equality Plans? Normative And Practical Challenges, Sara Clavero, Yvonne Galligan

Articles

This paper employs the concept of epistemic justice to examine the potential for gender equality plans (GEPs) to bring about sustainable transformative change towardsgender equality in higher education. Mindful of both the limitationsand opportunitiesof gender policy interventions,the paper highlights the importance of approaching gender inequality as a problem of justice and power rather than asan issueof “loss of talent.”The paper drawson Fricker's account of epistemic justice as well ason Bourdieu's analysis of power in the academic field, to evaluate seven GEPs in European universities for their potential to transform gender–power relations in academia.

Analysing Gender And Institutional Change In Academia: Evaluating The Utility Of Feminist Institutionalist Approaches, Sara Clavero, Yvonne Galligan

Concussion And The Severity Of Head Impacts In Mixed Martial Arts, Stephen Tiernan, Aidan Meagher, David O'Sullivan, Eoin O'Keefe, Eoin O'Kelly, Eugene Wallace, Colin Doherty, Mathew Campbell, Yuzhe Liu, August Domel

Articles

Background: Concern about the consequences of head impacts in US football motivated researchers to investigate and develop instrumentation to measure the severity of these impacts. However, the severity of head impacts in unhelmeted sports is largely unknown as miniaturised sensor technology has only recently made it possible to measure these impacts in vivo.

Aim: The objective of this study was to measure the linear and angular head accelerations in impacts in mixed martial arts (MMA), and correlate these with concussive injuries.

Methods: Thirteen MMA fighters were fitted with the Stanford instrumented mouthguard (MiG2.0). The mouthguard records linear acceleration and angular …

Measuring The Mathematical Problem Solving And Procedural Skills Of Students In An Irish Higher Education Institution – A Pilot Study, Fiona Faulkner, Mark Prendergast, Cormac Breen, Michael Carr

Articles

In 2010 the Irish second level mathematics curriculum underwent a period of significant change when a new mathematics curriculum was introduced. Some preliminary research has been carried out into the impact, if any, that this mathematics curriculum is having on students mathematics performance which have suggested that students’ procedural skills are declining year on year however their problem solving skills may have improved (Treacy and Faulkner 2015). Additional research in this area also highlighted that students willingness to engage in problem solving activities may have improved (Prendergast et al 2017). However preliminary analysis on the impact of the reformed mathematics …

Expectations Of Artificial Intelligence And The Performativity Of Ethics: Implications For Communication Governance, Aphra Kerr, Marguerite Barry, John D. Kelleher

Articles

This article draws on the sociology of expectations to examine the construction of expectations of ‘ethical AI’ and considers the implications of these expectations for communication governance. We first analyse a range of public documents to identify the key actors, mechanisms and issues which structure societal expectations around artificial intelligence (AI) and an emerging discourse on ethics. We then explore expectations of AI and ethics through a survey of members of the public. Finally, we discuss the implications of our findings for the role of AI in communication gover- nance. We find that, despite societal expectations that we can design …

Digital Age Of Consent And Age Verification: Can They Protect Children?, Liliana Pasquale, Paola Zippo, Cliona Curley, Brian O'Neill, Marina Mongiello

Articles

Children are increasingly accessing social media content through mobile devices. Existing data protection regulations have focused on defining the digital age of consent, in order to limit collection of children’s personal data by organizations. However, children can easily bypass the mechanisms adopted by apps to verify their age, and thereby be exposed to privacy and safety threats. We conducted a study to identify how the top 10 social and communication apps among underage users apply age limits in their Terms of Use. We also assess the robustness of the mechanisms these apps put in place to verify the age of …

Negative Curvature Hollow Core Fiber Based All-Fiber Interferometer And Its Sensing Applications To Temperature And Strain, Dejun Liu, Wei Li, Qiang Wu, Haoyu Zhao, Fengzi Ling, Ke Tian, Changyu Shen, Fangfang Wei, Wei Han, Gerald Farrell, Yuliya Semenova, Pengfei Wang

Articles

Negative curvature hollow core fiber (NCHCF) is a promising candidate for sensing applications; however, research on NCHCF based fiber sensors starts only in the recent two years. In this work, an all-fiber interferometer based on an NCHCF structure is proposed for the first time. The interferometer was fabricated by simple fusion splicing of a short section of an NCHCF between two singlemode fibers (SMFs). Both simulation and experimental results show that multiple modes and modal interferences are excited within the NCHCF structure. Periodic transmission dips with high spectral extinction ratio (up to 30 dB) and wide free spectral range (FSR) …

Nis2 As A Broadband Saturable Absorber For Ultrafast Pulse Lasers, Pengfei Wang, Han Zhang, Yu Yin, Qiuyun Ouyang, Yujin Chen, Elfed Lewis, Gerald Farrell, Masaki Tokurakawa, Sulaiman Wadi Harun, Cong Wang, Shi Li

Articles

Nickel disulfide (NiS2) has recently been found to possess strong nonlinear saturable absorption properties. This feature is highly attractive for nonlinear photonics applications. Ultrafast pulse generation is successfully demonstrated in this article for both Ytterbium- and Erbium-doped fibre lasers using micro-fibre deposited nickel disulfide (NiS2) as a saturable absorber (SA). The fabricated SA device has a modulation depth of 23% at 1.06 μm and 30.8% at 1.55 μm. Stable dissipative soliton operation was achieved at 1064.5 nm with a pulse duration of 11.7 ps and another stable conventional soliton pulse train was also obtained at 1560.2 nm with a pulse …

Intense Mid-Infrared Emission At 3.9 Μm In Ho3+-Doped Zbya Glasses For Potential Use As A Fiber Laser, Haiyan Zhao, Ruicong Wang, Xin Wang, Shijie Jia, Yaxian Fan, Elfed Lewis, Gerald Farrell, Shunbin Wang, Pengfei Wang

Articles

Intense mid-infrared emission at 3.9 µm in Ho3+-doped ZBYA glasses with direct upper laser level (Ho3+ : 5 I5) pumping at a wavelength of 888 nm is reported for the first time, to the best of our knowledge. Spectroscopic parameters were determined using the Judd–Ofelt theory and the measured absorption spectrum. The maximum emission cross section of the Ho3+-doped ZBYA glass is estimated to be 2.7 × 10−21 cm2 at 3906 nm. Additionally, fluorescence spectra and lifetimes of ZBYA glasses with different Ho3+ ion doping concentrations were measured. The results provide theoretical and experimental basis for better selection of rare-earth-doped …

The Historical Evolution Of The Methodology For Quantifying Federal Reserved Instream Water Rights For American Indian Tribes, Dylan R. Hedden-Nicely

Articles

From the earliest days of their relationship with the United States, the tribes from the region today referred to as the Northwestern United States have been steadfast in their effort to protect the land, waters, plants, and animals of their traditional homelands. That effort is not coincidental; North America's indigenous people have a singular relationship to the environment they have been a part of for millennia. In particular, they have relied on the streams of their territory for food, fiber, transportation, recreation, cultural, and spiritual sustenance. As a result, through litigation, restoration, and conservation management, tribes have focused on maintaining …

Innovation In A Legal Vacuum: The Uncertain Legal Landscape For Shared Micro-Mobility, David Pimentel

Articles

The last few years have seen an explosion in the number and size shared of micro-mobility systems (“SMMS”) across the United States. Some of these systems have seen extraordinary success and the potential benefit of these systems to communities is considerable. However, SMMS have repeatedly ran into legal barriers that either prevent their implementation entirely, confuse and dissuade potential users, or otherwise limit SMMS’s potential positive impact. This paper reflects a detailed study of state laws relating to SMMS and the platforms commonly used in these systems. The study uncovered many inconsistencies with micro-mobility laws across the country. Currently, many …

Advancement Of Predictive Modeling Of Zeta Potentials (Ζ) In Metal Oxide Nanoparticles With Correlation Intensity Index (Cii), Andrey A. Toropov, Natalia Sizochenko, Alla P. Toropova, Danuta Leszczynska, Jerzy Leszczynski

Articles

It was expected that index of the ideality of correlation (IIC) and correlation intensity index (CII) could be used as possible tools to improve the predictive power of the quantitative model for zeta potential of nanoparticles. In this paper, we test how the statistical quality of quantitative structure-activity models for zeta potentials (ζ, a common measurement that reflects surface charge and stability of nanomaterial) could be improved with the use of these two indexes. Our hypothesis was tested using the benchmark data set that consists of 87 measurements of zeta potentials in water. We used quasi-SMILES molecular representation to take …

Thermophotovoltaic Systems For Achieving High-Solar-Fraction Hybrid Solar-Biomass Power Generation, Cm Iftekhar Hussain, Aidan Duffy, Brian Norton

Articles

Medium operating temperature hybrid solar-biomass TPV power plant design requires complex integration of multiple high temperature processes with low band-gap TPV cells. A 0.72 eV band-gap GaSb TPV cell has been used in thermophotovoltaic (TPV) systems operating at temperatures above 1400 °C. Low band-gap TPV cells, such as InGaAs (Eg = 0.55 eV) and InAs (Eg = 0.36 eV) could enable a TPV system to operate optimally at temperatures ≈1000 °C. To examine this, two hybrid solar-biomass TPV system configurations are studied using TRNSYS simulation that incorporates a new algorithm for TPV. It is found that in a high solar …

A Preconditioned Lattice Boltzmann Flux Solver For Steady Flows On Unstructured Hexahedral Grids, Brendan Walsh, Fergal Boyle

Articles

The lattice Boltzmann flux solver (LBFS), first introduced by Shu et al. (2014) on structured meshes, allows fluid flow problems to be solved on unstructured meshes discretised by the finite volume method. The solver calculates the macroscopic fluxes at the cell interfaces from a local reconstruction of the lattice Boltzmann solution. In this paper the LBFS is extended to three-dimensional unstructured hexahedral meshes and a preconditioned lattice Boltzmann flux solver (PLBFS) is presented. The PLBFS involves applying the preconditioning technique proposed by Guo (2004) to the LBFS and is achieved by modifying the equilibrium distribution function used to calculate the …

Land-Based Wind Energy Cost Trends In Germany, Denmark, Ireland, Norway, Sweden And The Unitedstates, Aidan Duffy, Maureen Hand, Ryan Wiser, Eric Lantz, Alberto Dalla Riva, Volker Berkhout, Maria Stenkvist, David Weir, Roberto Lacal-Arántegui

Articles

This paper presents work by the International Energy Agency’s Task 26 ‘Cost of Wind Energy’ on technological and cost trends in land-based wind energy in six participating countries (Denmark, Germany, Ireland, Norway, Sweden, United States) and the European Union between 2008 and 2016. Results indicate that there is a general trend towards larger, taller machines with lower specific powers resulting in higher capacity factors, despite small falls in new site wind resources in most countries, while wind project capital costs and project finance costs also fell. This resulted in an average levelized cost of energy (LCOE) fall of 33% for …

Influence Of Graphene Oxide And Carbon Nanotubes On The Fatigue Properties Of Silica/Styrene-Butadiene Rubber Composites Under Uniaxial And Multiaxial Cyclic Loading, Zongchao Xu, Stephen Jerrams, Hao Guo, Yanfen Zhou, Liang Jiang, Yangyang Gao, Liqun Zhang, Li Liu, Shipeng Wen

Articles

The influence of equivalent replacement of silica (SiO2) by carbon nanotubes (CNT) or graphene oxide (GO) on the microstructure, mechanical and fatigue behaviors of SiO2/styrene-butadiene rubber (SBR) composites was investigated. Results showed that the synergistic effect between CNT (or GO) and SiO2 was beneficial for the filler network and improved the mechanical properties of SBR composites. Furthermore, the introduction of CNT (or GO) led to low crack growth rates and the crack propagation tips were easy to deflection. Under multiaxial fatigue conditions, the maximum engineering stress was determined to be a reliable fatigue life predictor for SBR composites.

The Contemporary Methodology For Quantifying Reserved Instream Flow Water Rights To Support Aquatic Habitat, Dylan R. Hedden-Nicely

Articles

Since time immemorial, indigenous people have relied on the streams of their territory for food, fiber, transportation, recreation, cultural, and spiritual needs. Accordingly, tribal people-particularly those in the region now called the Northwestern United States-placed singular emphasis on preserving their traditional subsistence culture when negotiating with the United States during the reservation era. Although rarely expressed in these treaties, the tribes are nonetheless entitled to water rights sufficient to fulfill these traditional subsistence treaty rights. Of the suite of water rights to maintain traditional uses of water, likely the most commonly claimed is for water to maintain fish habitat. A …
