Description: Monitoring of structures and defining the severity of damages that occur under loading are essential in practical applications of civil infrastructure. In this article, we analyze failure using a smart aggregate sensor–based approach. The signals captured by smart aggregate sensors mounted on the structure under loading are de-noised using wavelet de-noising technique to prevent misdirection of the event interpretation of what is happening in the material. The performance of different mother wavelets on the de-noising process was investigated and analyzed. The objective is to identify the optimal mother wavelet for assessing and potentially reducing the effects of existing noise on signal properties for structural damage detection. In addition, we propose two innovative damage indices, entropy-based dispersion and entropy-based beta, for diagnostic purposes. The proposed entropy-based dispersion damage index is based on the modified wavelet packet tree and root mean square deviation, whereas the entropy-based beta damage index is based on the modified wavelet packet tree and slope of linear regression (beta). In both damage indices, the modified wavelet packet tree uses entropy as a high-level feature. Theoretical and experimental analyses are derived by computing indices on smart aggregate–based sensor data for concrete and reinforced-concrete beams. Validity assessment of the proposed indices was addressed through a comparative analysis with root mean square deviation damage index (benchmark) and the loading history. The proposed indices recognized the cracks faster than other measures and well before major cracking incurs in the structure. This article is expected to be beneficial for smart aggregate–based structural health monitoring applications particularly when damages occurred under loading.

Description: In this paper, we consider the problem on exponential stability analysis of the stochastic impulsive high-order BAM neural networks with time delays. Through employing Lyapunov function method and stochastic bidirected halanay inequality, we constitute exponential stability of the stochastic impulsive high-order BAM neural networks with its estimated exponential convergence rate and feasible interval of impulsive strength. An example illustrates the main results. © 2012 Springer-Verlag London Limited.

Description: The government of Australia is supporting the statement that sea levels are rising faster than ever before as a result of increased carbon dioxide emissions. Consequent to this, low-lying coastal areas, where the majority of Australians are concentrated, have been declared at risk of sea level inundations. Maps with 0.5, 0.8 and 1.1 m sea level rise have been proposed for Sydney, the major Australian city. However, long term tide gauges, recording sea levels worldwide, as well as along the coastline of Australia, and within the bay of Sydney, do not show any sign of accelerating sea level rises at present time.

Description: Background: The effects of foot posture on the dynamic function of the lower limb during gait remains relatively unknown. Objectives: The purpose of this study was to investigate lower limb kinematics between the normal and low arched foot during the gait cycle, particularly in the transverse plane. Method: Twenty-four children, twelve with normal and twelve with low arched feet, aged 11-12 years underwent a lower limb three dimensional gait analysis. Temporo-spatial parameters and patterns and ranges of motion of kinematic data were examined for the pelvis, hip, knee and ankle throughout the gait cycle. Results: Overall, there were very few differences found in the kinematics of the lower limbs between the normal and low arched group. Increased external hip rotation (6-7°) in the low arched group was the only bilateral significant difference (p < 0.05) between the two foot groups. No significant differences existed in any temporo-spatial parameters between the two groups. Conclusions: The increased external hip rotation and greater external foot progression angle in the low arched foot highlights the need to examine gait comprehensively to establish cause or effect of these differences observed and hence determine appropriate treatment. © 2011 Elsevier Ltd.

Description: Sports injuries are a significant clinical and public health concern. There is a growing call to improve the translation of available evidence-based and expert-informed sports injury prevention interventions into sustained use in practice by physicians and others (eg, athletic trainers, coaches, and parents) who care for injured athletes. This article provides a brief overview of the current sport injury prevention implementation literature before focusing specifically on the translation of guidelines (including consensus and position statements) developed to assist physicians and others diagnose and manage athletes with sport-related concussion and the associated return-to-play decisions. The outcomes of more than 20 published studies indicate that physician, athletic trainer, coach, parent, and athlete knowledge, use of, and compliance with sport-related concussion guidelines are limited. More concerted, coordinated, and theory-informed efforts are required to facilitate the widespread dissemination, translation, and implementation of such guidelines. An example is provided of how implementation drivers could be used to inform the development of a comprehensive, multilevel implementation strategy targeting the individual, organizational, and system-level changes necessary to support the translation of available sport-related concussion guidelines in both the clinical and sports settings.
