Intercalation, decomposition, entrapment a new route to graphene nanobubbles.
Venue: Physical chemistry chemical physics PCCP
Year: 2020

Graphene nanobubbles (GNBs) have become the subject of recent research due to their novel physical properties. However, present methods to create them involve either extreme conditions or complex sample fabrication. We present a novel approach which relies on the intercalation of small molecules (NH3) their surface mediated decomposition and the formation of larger molecules (N2) which are then entrapped beneath the graphene in bubbles. Our hypothesised reaction mechanism requires the copper substrate, on which our graphene is grown via chemical vapour deposition (CVD) to be oxidised before the reaction can occur. This was confirmed through X ray photoelectron spectroscopy (XPS) data of both oxidised and reduced Cu substrate samples. The GNBs have been analysed through atomic force microscopy (AFM, after NH3 treatment) and XPS, which reveals the formation of five distinct N 1s peaks, attributed to N2 entrapment, N doping species and atomic nitrogen bonded with the Cu within the substrate. This method is simple, occurs at low temperatures (520 K) and integrates very easily with conventional CVD graphene growth, so presents an opportunity to open up this field of research further.
The Influence of Support and Development Programs and Services on the Success of University Students from Low Socioeconomic Status Backgrounds
Year: 2016

This project engaged a mixed methods approach to explore how the success of students from low socioeconomic status (low SES) backgrounds was impacted by their interaction with support and development initiatives offered by the division of Student Life and Learning at UNSW Australia. A quantitative database study was used to determine the impact of intervention on several academic success indicators, and multilevel modelling was applied to identify significant results. Student interviews provided experiential accounts of support initiative interaction, which were drawn on to qualify the link between interaction and success. The initiatives examined were academic writing, disabilities, counselling, educational and careers support services, and co curricular development programs. Findings show that low SES students accessed Student Life and Learning support initiatives at similar or (in the case of some initiatives) higher rates than their peers and that these interactions contributed in multiple and diverse ways to student success. The benefits provided by interactions were not limited to low SES students, although there is some evidence to suggest that academic improvements may be more pronounced for this cohort.

Improving Security Message Adherence through Improved Comprehension: Neural and Behavioral Insights
Venue: AMCIS
Year: 2018

Security warnings are critical to help users make contextual security decisions. Unfortunately, users find these warnings hard to understand, and they routinely expose themselves to unintended risks as a result. Although it is straightforward to determine when users fail to understand a warning, it is more difficult to pinpoint why this happens. The goal of this research is to use eye tracking to step through the building blocks of comprehension attention, semantics, syntax, and pragmatics for SSL and other common security warnings. Through this process, we will identify ways to design security warnings to be more easily understood.

LUNGx Challenge for computerized lung nodule classification: reflections and lessons learned.
Venue: Journal of medical imaging
Year: 2015

Challenges, in the context of medical imaging, are valuable in that they allow for a direct comparison of different algorithms designed for a specific radiologic task, with all algorithms abiding by the same set of rules, operating on a common set of images, and being evaluated with a uniform performance assessment paradigm. The variability of system performance based on database composition and subtlety, definition of "truth," and scoring metric is well known;1 3 challenges serve to level the differences across these various dimensions. The medical imaging community has hosted a number of successful thoracic imaging challenges that have spanned a wide range of tasks,4,5 including lung nodule detection,6 lung nodule change, vessel segmentation,7 and vessel tree extraction.8 Each challenge presents its own unique set of circumstances and considerations; however, important common themes exist. Future challenge organizers (and participants) could benefit from an open discussion of successes achieved, pitfalls encountered, and lessons learned from each completed challenge.

Venue: 2020 IEEE International Conference for Innovation in Technology (INOCON)
Year: 2020

In the time of globalization, there is a requirement for conquering the language barrier and interfacing with an ever increasing number of individuals. The value of speaking to customers in their language is tangible with retention and engagement rates up over 70% when there are effective localization workflows in place. To do this, integrating Neural Machine Translation into traditional localization workflows is an efficient way. In this paper, we break down different models, approaches, inception, principle development, and structures utilized in NMT to discover a productive strategy to make a translation system and identifying the advances and imperfections of the equivalent. It also talks about evolution of various NMT techniques leading to the current methodologies and numerous challenges which could be taken further for future research trends and improvements carried on them.
Reliable flight control system architecture for agile airborne platforms: an asymmetric multiprocessing approach
Venue: The Aeronautical Journal
Year: 2019

System software subsystems in an unmanned aircraft system share hardware resources due to space, weight, and power constraints. Such subsystems have different criticality, requirements, and failure rates, and can cause undesired interference when sharing the same hardware. A component with high failure rate can reduce the reliability of the system unless a fault containment mechanism is adopted. This work proposes an asymmetric multiprocessor architecture to establish isolation at the hardware level for distributed implementation of safety critical subsystems along with user defined payload subsystems on the same hardware with minimally reduced reliability of the system. To achieve that, subsystems are strategically segregated in separate processors, connected to an on chip protective interconnect for inter processor communications. A custom watchdog and reset mechanism are implemented to reset a specific processor without affecting the entire system if required. The architecture is demonstrated on a FPGA chip. In addition, an example of an optimised distribution is provided for a specific flight control system with five subsystems.
How You Can Work to Increase the Presence and Improve the Experience of Black, Latinx, and Native American People in the Economics Profession
Year: 2020

Recently in economics there has been discussion of how to increase diversity in the profession and how to improve the work life of diverse peoples. We conducted surveys and interviews with Black, Latinx and Native American people. These groups have long been underrepresented in the economics profession. Participants were at various stages along the economics career trajectory, or on the trajectory no longer, and used their lived experience to reflect on what helps and hurts underrepresented minorities in economics. We heard a few consistent themes: bias, hostile climate, and the lack of information and good mentoring among them. Respondents' insights and experience point toward action steps that you can take today to increase the presence and improve the work life of underrepresented minorities in the economics profession.
Motivational Potential of Mobile Foreign Language Learning Applications Duolingo and Memrise and Their Use Among University Students in Croatia
Year: 2019

Mobile language learning applications, such as Duolingo and Memrise, have enabled virtually everyone to autonomously learn numerous foreign languages. This paper is based on a research into opinions and practices of students from the Faculty of Teacher Education of the University of Zagreb in Croatia, who have used the aforementioned applications to learn at least one foreign language. The responses were mostly positive: respondents were very interested or highly interested in learning a foreign language (83.6% they liked the gamification quality of the foreign language applications (80.1% they learned how to use them quickly or very quickly (85.4% and they liked the fact that they can use the applications whenever and wherever they want (77.6% On the other hand, only 24% of respondents completely agreed with the statement that they would be able tolearn a foreign language using one or more such mobile applications. A follow up research proposed in order to encompass other mobile learning applications, and to ascertain whether the high motivational factor would remain constant notwithstanding the repetitive nature of the exercises provided by these applications.
Distorted body image influences body schema in individuals with negative bodily attitudes
Venue: Neuropsychologia
Year: 2019

There is now a considerable body of evidence to suggest that internal representations of the body can be meaningfully separated into at least two general levels; body image as a perceptual construct and body schema as a motor metric. However, recent studies with eating disordered individuals have suggested that there may in fact be more interaction between these two representations than first thought. We aimed to investigate how body image might act to influence body schema within a typical, healthy population. 100 healthy adult women were asked to judge the smallest gap between a pair of sliding doors that they could just pass through. We then determined whether these estimates were sufficient to predict the size of the smallest gap that they could actually pass through, or whether perceptual and attitudinal body image information was required in order to make these predictions. It was found that perceptual body image did indeed mediate performance on the egocentric (but not allocentric) motor imagery affordance task, but only for those individuals with raised body image concerns and low self esteem; body schema was influenced by both the perceptual and attitudinal components of body image in those with more negative bodily attitudes. Furthermore, disparities between perceived versus actual size were associated with body parts that had larger variations in adipose/muscle dependent circumference. We therefore suggest that it may be the affective salience of a distorted body representation that mediates the degree to which it is incorporated into the current body state. HIGHLIGHTSBMI and attitudinal body image were predictive of participants' perceptual body image judgements.Affordance judgments were only influenced by body areas with large variation in adiposity/muscle.In women with bodily concerns affordance judgements incorporate distorted perceptual body image.Body schema was influenced by both the perceptual and attitudinal components of body image.
Dagger: Towards Efficient RPCs in Cloud Microservices With Near Memory Reconfigurable NICs
Venue: IEEE Computer Architecture Letters
Year: 2020

Cloud applications are increasingly relying on hundreds of loosely coupled microservices to complete user requests that meet an application's end to end QoS requirements. Communication time between services accounts for a large fraction of the end to end latency and can introduce performance unpredictability and QoS violations. This letter presents our early work on Dagger, a hardware acceleration platform for networking, designed specifically with the unique qualities of microservices in mind. The Dagger architecture relies on an FPGA based NIC, closely coupled with the processor over a configurable memory interconnect, designed to offload and accelerate RPC stacks. Unlike the traditional cloud systems that use PCIe links as the NIC I/O interface, we leverage memory interconnected FPGAs as networking devices to provide the efficiency, transparency, and programmability needed for fine grained microservices. We show that this considerably improves CPU utilization and performance for cloud RPCs.

An inverse design method with aerodynamic design optimization for wing glove with hybrid laminar flow control
Year: 2019

The design of the hybrid laminar flow control (HLFC) system involves the comprehensive design of the suction control and the profile, and it has become an urgent problem for a three dimensional shape design with the consideration of HLFC technology, especially in condition of the high Reynolds number with the large sweep angle. In order to deal with this issue, this paper conducts an inverse design method combining a design optimization oriented by pressure distribution. This methodology prescribes a target pressure distribution and then uses the optimization method to pursue the corresponding shape that matches the target pressure distribution. The optimization framework is mainly based on the particle swarm optimization algorithm and the Kriging surrogate model. The studied model is a wing glove, and the results show that the desired robust wing glove that meets the engineering requirements can be efficiently obtained. The optimized wing glove has a long enough laminar zone with the help of suction control, and it shows good robustness with the variation of sideslip angles and angles of attack.
Schadensaggregation in der Ruckversicherung die Principles of Reinsurance Contract Law (PRICL) als Mittel zur Schaffung hoherer Rechtssicherheit?
Venue: Zeitschrift fur die gesamte Versicherungswissenschaft
Year: 2020

Kaum eine Rechtsordnung kennt Regeln fur die Schadenaggregation in der Ruckversicherung. Eine Ausnahme bietet das englische Recht, wo sich diesbezuglich eine reiche Rechtsprechung entwickelt hat. Eine Analyse dieser Rechtsprechung zeigt, dass im Bereich der Schadenaggregation in der Ruckversicherung terminologische Unsicherheiten bestehen und dass die von der Rechtsprechung entwickelten Beurteilungsmassstabe nicht geeignet sind, Rechtssicherheit herzustellen. Dieser Zustand wird der Bedeutung der nichtproportionalen Ruckversicherung nicht gerecht. Mit dem Ziel, den Ruckversicherungsmarkten mehr Rechtssicherheit zu bieten, schlagt Kapitel 5 der Principles of Reinsurance Contract Law (PRICL) neu konzipierte Regeln zur Schadenaggregation vor.
Forecasting Threats and Opportunities for Foreign Innovators in China's Strategic Emerging Industries: A Policy Based Analysis
Year: 2016

This article reviews over 50 recent Chinese policies designated to develop China's "strategic emerging industries" (SEIs) and conducts interviews with foreign firms and Chinese government officials to identify the most significant threats and opportunities for foreign innovators in these industries. Threats identified include initiatives to stimulate the market primarily in the interest of Chinese firms, cultivate "indigenous" intellectual property (IP) rights, and create national champions in specific SEIs. Opportunities include using certain strategies to tap into monetary stimuli for SEIs and supporting industries, benefits from further regionalization and optimization of industrial bases, direct benefits and spillovers from improved IP protection and management, and potential opportunities from increased M&A by Chinese firms. These findings should be contextualized with the knowledge that not all aspects of the SEIs' initiative are "new" current Chinese industrial policy does not only target seven SEIs, and SEI policies may not all work exactly as intended.
A review of turbulence measurements using ground based wind lidars
Year: 2013

A review of turbulence measurements using ground based wind lidars is carried out. Works performed in the last 30 yr, i.e. from 1972 2012 are analyzed. More than 80 of the work has been carried out in the last 15 yr, i.e. from 1997 2012. New algorithms to process the raw li dar data were pioneered in the first 15 yr, i.e. from 1972 1997, when standard techniques could not be used to measure turbulence. Obtaining unfiltered turbulence statistics from the large probe volume of the lidars has been and still remains the most challenging aspect. Until now, most of the process ing algorithms that have been developed have shown that by combining an isotropic turbulence model with raw lidar mea surements, we can obtain unfiltered statistics. We believe that an anisotropic turbulence model will provide a more realistic measure of turbulence statistics. Future development in algo rithms will depend on whether the unfiltered statistics can be obtained without the aid of any turbulence model. With the tremendous growth of the wind energy sector, we expect that lidars will be used for turbulence measurements much more than ever before.

Design of Power and Area Efficient Approximate Multipliers
Year: 2017

Approximate computing can decrease the design complexity with an increase in performance and power efficiency for error resilient applications. This brief deals with a new design approach for approximation of multipliers. The partial products of the multiplier are altered to introduce varying probability terms. Logic complexity of approximation is varied for the accumulation of altered partial products based on their probability. The proposed approximation is utilized in two variants of 16 bit multipliers. Synthesis results reveal that two proposed multipliers achieve power savings of 72% and 38% respectively, compared to an exact multiplier. They have better accuracy when contrasted with existing estimated multipliers. Mean relative blunder figures are as low as 7.6% and 0.02% for the proposed inexact multipliers, which are superior to the past works. Execution of the proposed multipliers is assessed with a picture handling application, where one of the proposed models accomplishes the most astounding pinnacle flag to commotion proportion.
Student attitude towards Mathematics and performance: Does the teacher attitude matter?
Year: 2013

The indispensable role of attitude in the learning of Mathematics has garnered the attention of educational researchers and Mathematics educators for a very long time. Hence, literature is replete with empirical evidence on the relationship between teacher attitude and student academic performance in Mathematics. The study was fashioned to extend the discussion to the influence of teacher attitude on student attitude. The samples for the study were one hundred students and four Mathematics teachers making a total of one hundred and four respondents. The students were randomly selected while the teachers were purposively sampled. Two sets of questionnaires were used to gather data from the respondents after they had been validated and their reliability established. Students' end of term examination scores were used as a measure of students' academic achievements. The study unveiled a significant relationship between teacher attitude and student attitude toward Mathematics. It was realised that teachers' positive attitude radiated confidence in students hence made them develop positive attitude towards the learning of Mathematics. The results of the study were also consistent with existing findings on the relationship between teacher attitude and students' performance in Mathematics. Implications of the findings are discussed and recommendations have been proffered for practice.  Mathematics, teacher attitude, student attitude, student performance, influence and relationship
