XGBoost automates the characterisation of reversibly actuating planar-flow-casted NiTi shape memory alloy foil

Nickel-Titanium (NiTi) shape memory alloys (SMAs) are smart materials able to recover their original shape under thermal stimulus. Near-net-shape NiTi SMA foils of 2 meters in length and width of 30 mm have been successfully produced by a planar flow casting facility at CSIRO, opening possibilities of wider applications of SMA foils. The study also focuses on establishing a fully automated experimental system for the characterisation of their reversible actuation, significantly improving SMA foils adaptation into real applications. Artificial Intelligence involving Computer Vision and Machine Learning based methods were successfully employed in the development of the automation SMA characterisation process. The study finds that an Extreme Gradient Boosting (XGBoost) Regression model based predictive system experimented with over 175,000 video samples could achieve 99% overall prediction accuracy. Generalisation capability of the proposed system makes a significant contribution towards the efficient optimisation of the material design to produce high quality 30 mm SMA foils.

Objective: This thesis addresses a neglected aspect of bioinformatics research of hemifacial microsomia (HFM). Existing research stops short of prediction based on big data. This study combines multiple databases to explore underlying pathogenesis using bioinformatic approach. Methods: The research consisted of multiple bioinformatic methods, included pathogenic genes analyses, protein-protein interaction network construction, functional enrichment, and mining target genes related miRNA, for studying pathogenic genes of HFM. Results: Total of 140 genes were identified as potential genes in the study. The protein-protein interaction networks for pathogenic genes were constructed, which contained 138 nodes and 243 edges with RAF1, MAP2K1, MAP2K2, MAPK3, MAPK1, EGFR, BRAF, LMNA, ESPR1, and SFN as the hub genes. These genes were discovered significantly enriched in MAPK pathway. Besides, the whole of interactions between miRNAs and the top 5 hub genes were revealed. Conclusions: Our results indicated that occurrence of HFM is attributed to a variety of genes. Furthermore, the interactions of pathogenic genes were further elucidated by using bioinformatics approach. It reveals the MAPK pathway play an essential role in its pathogenesis. It may provide a novel perspective on better understanding the pathogenesis and more accurate early screening of HFM.

Power quality and stability improvement of a wind farm using STATCOM supported with hybrid battery energy storage

A large penetration of wind generation info the power system will mean that poor power quality and poor stability margins cannot be tolerated from wind farms. This requires that methods to improve power qualify and stability for such systems be found. The static compensator (STATCOM) with hybrid battery energy storage (BES) has great potential to fulfil this role, though considerable advances in the control of this system are still to be made. From an economic point of view, rating the STATCOM for steady-state power-quality improvement duty is appropriate. Rating the STATCOM to absorb large amounts of additional power in excess of its transient overload capability during network faults is inappropriate. A hybrid of BES and braking resistor is therefore proposed. A new hybrid STATCOM–BES control technique is developed and discussed in the context of improving the stability and power quality to fixed speed, induction generator, wind turbines. The variation of the network voltage, active and reactive power with the fluctuation of the wind generation is studied. A wind generation system with a STATCOM battery energy storage unit and the new control was simulated and the results demonstrate that both power quality and the stability margin can be improved significantly for wind farms.
Review of air-cooling strategies, combinations and thermal analysis (experimental and analytical) of a permanent magnet synchronous motor

This paper gives a brief review of advanced cooling methods and applications to the permanent magnet synchronous motors (PMSMs), as well as investigates the cooling systems design problem for PMSM systems. Heat sources and losses together with analytical and practical analyses are described. Next, the temperature distribution and its influence on the PMSM is investigated using simulation results. The main part of the paper includes a review of the proposed cooling methods that will release the requirement of heat transfer of the PMSM. The finite element methods (FEM) are applied using the AnSys CFD software to obtain high accuracy thermal model of the PMSM system. The new developed forced air-cooling methods are given in details, which enable to effectively redistribute the temperature and heat transfer increasing the efficiency of the PMSM machine. Examples of CFD simulation are outlined to illustrate the effectiveness and benefits of the strategies developed.
The DSSATv4.5 Canegro model: a useful decision support tool for research and management of sugarcane production.

THE NEW DSSATv4.5 Canegro model allows users to combine the latest advances in sugarcane modelling with the latest DSSAT functionality to address production and research problems. The objectives of this poster are to (1) describe the main features of the model, (2) report on its accuracy of simulating biomass, cane and sucrose yields in different parts of world, and (3) highlight potential applications in sugarcane research and management. The model uses daily weather data to simulate canopy development, interception of radiation, biomass accumulation and partitioning. It simulates the effect of water stress and lodging on photosynthesis, growth and sucrose storage. Eighteen cultivar parameters are used to simulate genetic control of crop response to environmental factors. Simulated green leaf area index, aboveground biomass, stalk mass and sucrose mass were compared with observed data from Australia, Brazil, South Africa, Thailand and Zimbabwe. The model performed remarkably well for these widely different cropping situations and cultivar types. In some cases, the simulated biomass accumulation rates declined too rapidly in winter leading to an underestimation of yields. This needs further investigation. The DSSATv4.5 Canegro model is now easily accessible and may be applied, after thorough testing, to support research and management world-wide.
Gas Path On-line Fault Diagnostics Using a Nonlinear Integrated Model for Gas Turbine Engines

Abstract Gas turbine engine gas path fault diagnosis is closely related technology that assists operators in managing the engine units. However, the performance gradual degradation is inevitable due to the usage, and it result in the model mismatch and then misdiagnosis by the popular model-based approach. In this paper, an on-line integrated architecture based on nonlinear model is developed for gas turbine engine anomaly detection and fault diagnosis over the course of the engine's life. These two engine models have different performance parameter update rate. One is the nonlinear real-time adaptive performance model with the spherical square-root unscented Kalman filter (SSR-UKF) producing performance estimates, and the other is a nonlinear baseline model for the measurement estimates. The fault detection and diagnosis logic is designed to discriminate sensor fault and component fault. This integration architecture is not only aware of long-term engine health degradation but also effective to detect gas path performance anomaly shifts while the engine continues to degrade. Compared to the existing architecture, the proposed approach has its benefit investigated in the experiment and analysis.
VAPBr: Values in Digital Games for Public Service in Brazil

In Brazil, many initiatives have emerged to promote the dialogue between citizens and public institutions using technology. This dialogue has been a challenging endeavor, and digital games have been proposed to stimulate interaction and understanding about public service process delivery. In this context, one fundamental aspect observed for the effectiveness of these games is the human values that the games can transmit. This paper proposes the “Values at Play Brazil” (VAPBr), a deck composed of 24 cards as a brainstorming tool to help designers identify values for public process-based digital games. The paper describes the design of VAPBr and its evaluation with 14 game designers aiming to obtain participants’ perception of VAPBr capability of clearly describing values and its usefulness for identifying them for a game. Results show a positive perception of VAPBr as a brainstorming tool to discover values to be designed in a public processbased digital game.
Evaluating Aging Properties of Crumb Rubber and Styrene–Butadiene–Styrene Modified Binders

In recent years, one of the questions about modified binders has been the durability of their improved performance throughout their service life. Aging properties of modified binders in various frequency and temperature ranges depend on the class and concentration of the modifiers as well as the binder type. The aging characteristics have been evaluated in several ways, but the use of master curve models for modified binders has received little attention because of the lack of appropriate models with an easily manageable number of parameters. A recently developed mathematical model, Double Logistic (DL), can be used to characterize the master curves of modified binders. For the investigation of the rheological properties of aged and unaged modified binders, two modifiers, styrene–butadiene–styrene and ground tire rubber, were selected. Two binder types were selected to evaluate the binder dependency of the results. All modified binders were subjected to short- and long-term aging conditions in the laboratory. Then the rheological master curves of the complex modulus and phase angle of all the binders in various aging conditions were generated and fitted by the DL model. The model correctly predicted the phase angle plateau values and other irregularities for many polymer-modified binders in several aging conditions in this research. In addition, the DL model captured aging behaviors, such as hardening or softening, more elastic or viscous response, and lower or higher temperature susceptibility of the neat and polymer modified binders at various temperature and frequency ranges.
Correlation of neutrophil-to-lymphocyte ratio and clinical outcome of acute thrombotic stroke in patients with COVID-19

The coronavirus disease 2019 (COVID-19) pandemic has caused millions of deaths worldwide. Acute ischemic stroke is a life-threatening risk factor for COVID-19 infection. Neutrophil-to-lymphocyte ratio (NLR) is one of the predictors of poor prognosis in acute ischemic stroke. The aim of this study was to assess the correlation between NLR values and the clinical outcome of acute thrombotic stroke patients with COVID-19 that was measured using the National Institutes of Health Stroke Scale (NIHSS). A cross- sectional hospital-based study was conducted in Dr. Soetomo General Hospital Surabaya, Indonesia. Patients with acute thrombotic stroke and COVID-19 admitted between 1 March 2020 and 31 May 2021 were recruited. The NLR values and the NIHSS scores were assessed during the admission and the correlation between NLR and NIHSS scores was calculated. This study included 21 patients with acute thrombotic stroke and COVID-19, consisting of 12 males and 9 females. The mean age was 57.6 years old. The mean NLR values was 8.33±6.7 and the NIHSS scores ranging from 1 to 33. Our data suggested a positive correlation between NLR values and NIHSS scores, r=0.45 with p=0.041. In conclusion, the NLR value is potentially to be used as a predictor of the clinical outcome in acute thrombotic stroke patients with COVID-19. However, further study is warranted to validate this finding.
Numerical Study on the Bombardment Effects of Tungsten by High-Intensity Pulsed Ion Beam

In order to study the response of tungsten under high heat load, the nonlinear thermodynamic equations considering the phase transition were established to the tungsten target irradiated by intense pulsed ion beam. Also the equations which describe the thermal stress and the total strain produced by the changed temperature in the material element were built. Numerical method was used to solve the evolutions of the thermal stress field formed in the target, and spatial temporal evolutions of stress field in the tungsten target are obtained. While the ion current density reached 100A/cm2, the surface materials of tungsten target at the beam incident center was melted and then re-solidified due to the heat conduction after the end of a pulse. There exists the gradient of temperature in tungsten, therefore the thermal stress formed. Radial tensile stress is produced within the melting region, meanwhile outside the region compressive stress is formed; the boundary appears on the edge of the melting region. The stresses on the incidental surface of target are larger compared with the internal.
Endoscopic Submucosal Dissection Skills Transfer to Clinical Practice after Hands-On Workshops: An International Survey

Background: Endoscopic submucosal dissection (ESD) is a complex procedure, requiring enhanced technical skills. Translation into clinical practice of ESD training programs has not been documented. Our aim was to assess ESD training pathways of endoscopists participating in dedicated workshops and its clinical impact on ESD outcomes. Methods: Participants of live porcine models ESD workshops, from 2013 to 2019, were included. They were invited to complete a survey focusing on human ESD performance after training, prior skills/competencies, complete learning pathway, and clinical outcomes. Results: From 118 invited participants, 40 (34%) completed the questionnaire. Nineteen (47%) endoscopists performed human ESD after the workshop, predominantly male (89%). At the beginning of human ESD, endoscopists had a mean of 7.7 (standard deviation (SD) 4.1) years of endoscopic experience and were all performing endoscopic mucosal resection (and emergency endoscopy. Before ESD practice, 100% of the participants were trained with live animal models and 68% with ex vivo models. The majority started clinical ESD in the lower third of the stomach or rectum (90%), with lesions ≤30 mm (89%). Each endoscopist performed a median of 19 (interquartile range 8–32) cumulative ESDs, over a mean of 3.9 (SD 2.0) years. Total en bloc resection rate was 92%, R0 resection rate 88%, and curative resection rate 86%, whereas adverse events remained <10%. Endoscopists with >10 human ESD procedures achieve clinical competence thresholds. Conclusions: Participants of ESD workshops are adequately skilled prior to clinical ESD, complying with recommendations for training and properly implementing the technique. Transfer to clinical practice, of prior ESD skills obtained in hands-on training courses, was documented. Structured training programs achieve clinical outcomes exceeding established standards, namely in the very initial clinical phase.
New insights in the relation between electron trap generation and the statistical properties of oxide breakdown

In this paper it is demonstrated in a wide stress field range that breakdown in thin oxide layers occurs as soon as a critical density of neutral electron traps in the oxide is reached. It is proven that this corresponds to a critical hole fluence, since a unique relationship between electron trap generation and hole fluence is found independent of stress field and oxide thickness. In this way literature models relating breakdown to hole fluence or to trap generation are linked. A new model for intrinsic breakdown, based on a percolation concept, is proposed. It is shown that this model can explain the experimentally observed statistical features of the breakdown distribution, such as the increasing spread of the Q/sub BD/-distribution for ultrathin oxides. An important consequence of this large spread is the strong area dependence of the Q/sub BD/ for ultrathin oxides.
Coplanar corporate feed effects in microstrip patch array design

The use of coplanar corporate feeds for microstrip patch arrays leads to constructional simplicity, but also to performance degradations due to feed radiation, in addition to limitations due to feed resistive loss, surface waves, mutual coupling and tolerances. These effects are quantified, and this allows specification of array performance limitations in addition to the recommendation of the use of smooth feed discontinuities, high line impedance, and thin substrates. Improvements due to the use of alternate feed geometries, such as sequentially rotated feeding and subarraying, are also quantified and are shown to be substantial.
Design of unknown inputs robust fuzzy observer for lane departure detection

A lane departure detection method is proposed using Takagi-Sugeno (T-S) fuzzy approach in this paper. To deal with this problem, a nonlinear model deduced from a vehicle lateral dynamic and a vision system is represented by an uncertain T-S fuzzy model affected by unknown inputs. The developed lane departure detection technique is based on an unknown inputs fuzzy observer. Design conditions of such observers are expressed in terms of Linear Matrix Inequalities (LMI). Indeed, the road curvature considered as unknown input is estimated and compared to the vehicle trajectory curvature. The proposed algorithm allows to reduce false alarms and to integrate the driver corrections by taking the steering dynamics into account. In order to show the ef? ciency of the given method, simulations with different driving scenarios are proposed.
Integrated Localization and Tracking for AUV With Model Uncertainties via Scalable Sampling-Based Reinforcement Learning Approach

This article studies the joint localization and tracking issue for the autonomous underwater vehicle (AUV), with the constraints of asynchronous time clock in cyberchannels and model uncertainty in physical channels. More specifically, we develop a reinforcement learning (RL)-based asynchronous localization algorithm to localize the position of AUV, where the time clock of AUV is not required to be well synchronized with the real time. Based on the estimated position, a scalable sampling strategy called multivariate probabilistic collocation method with orthogonal fractional factorial design (M-PCM-OFFD) is employed to evaluate the time-varying uncertain model parameters of AUV. After that, an RL-based tracking controller is designed to drive AUV to the desired target point. Besides that, the performance analyses for the integration solution are also presented. Of note, the advantages of our solution are highlighted as: 1) the RL-based localization algorithm can avoid local optimal in traditional least-square methods; 2) the M-PCM-OFFD-based sampling strategy can address the model uncertainty and reduce the computational cost; and 3) the integration design of localization and tracking can reduce the communication energy consumption. Finally, simulation and experiment demonstrate that the proposed localization algorithm can effectively eliminate the impact of asynchronous clock, and more importantly, the integration of M-PCM-OFFD in the RL-based tracking controller can find accurate optimization solutions with limited computational costs.
Low‐profile multibranch monopole antenna with integrated matching circuit for Lte/Wwan/Wlan operation in the tablet computer

A low profile, small‐size, planar tablet computer antenna for the long‐term evolution (LTE)/wireless wide area network and 2.4‐GHz WLAN operation is presented. The antenna is formed by three monopole strips configured into a compact configuration and printed on a thin FR4 substrate of size 10 × 40 mm2. A high‐pass matching circuit is integrated thereon, without increasing the antenna size, to greatly enhance the antenna's low‐band bandwidth to cover the LTE700/GSM850/900 operation (704–960 MHz) with a low‐antenna profile of 10 mm. The antenna's higher band is formed by two wide resonant modes contributed by the monopole strips and can cover the GSM1800/1900/UMTS/LTE2300/2500 operation (1710–2170/2300–2400/2500–2690 MHz). In addition, one of the resonant modes in the higher band can be adjusted to occur at about 2.4 GHz such that enhanced radiation characteristics for frequencies in the 2400–2484‐MHz WLAN band are obtained for the proposed antenna. © 2014 Wiley Periodicals, Inc.

EHR STAR: The State‐Of‐the‐Art in Interactive EHR Visualization

Since the inception of electronic health records (EHR) and population health records (PopHR), the volume of archived digital health records is growing rapidly. Large volumes of heterogeneous health records require advanced visualization and visual analytics systems to uncover valuable insight buried in complex databases. As a vibrant sub‐field of information visualization and visual analytics, many interactive EHR and PopHR visualization (EHR Vis) systems have been proposed, developed, and evaluated by clinicians to support effective clinical analysis and decision making. We present the state‐of‐the‐art (STAR) of EHR Vis literature and open access healthcare data sources and provide an up‐to‐date overview on this important topic. We identify trends and challenges in the field, introduce novel literature and data classifications, and incorporate a popular medical terminology standard called the Unified Medical Language System (UMLS). We provide a curated list of electronic and population healthcare data sources and open access datasets as a resource for potential researchers, in order to address one of the main challenges in this field. We classify the literature based on multidisciplinary research themes stemming from reoccurring topics. The survey provides a valuable overview of EHR Vis revealing both mature areas and potential future multidisciplinary research directions.
