  • Structural health monitoring using adaptive LMS filters

    A structure's level of damage is determined using a non-linear model-based method utilising a Bouc-Wen hysteretic model. It employs adaptive Least Mean Squares (LMS) filtering theory in real time to identify changes in stiffness due to modelling error damage, as well as plastic and permanent displacements, which are critical to determining ongoing safety and use. The Structural Health Monitoring ...

  • Damage detection utilising the artificial neural network methods to a benchmark structure

    This paper discusses the damage identification using artificial neural network (ANN) methods for the benchmark problem set up by IASC-ASCE Task Group on Health Monitoring. A three-stage damage identification strategy for building structures is proposed. The BP network and probabilistic neural network (PNN) are employed for damage localisation and BP network for damage extent identification. Four ...

  • Causal-effect structure transformation based on hierarchical representation for biomedical sensing

    In general, understanding causality among components in a target system, including a human body, is quite effective and efficient solution since utilisation of the causality helps predicting future system condition, making correct diagnosis and so forth. As for focusing on biomedical sensing, the causality among vital signals obtained from sensors built in measurement equipment should be ...

  • How Accurate is Your Monitor?

    When you consider the many regulations and guidelines that health and safety officers and first responders are faced with, it is amazing they maintain the ability to detect such a wide variety of hazardous pollutants and toxic agents.  There is no lack of regulations governing how to monitor chemical compounds, and the list grows longer all the time.  New standards for portable gas ...

  • Study on method for assessment of the physical structure integrity in Chagan lake in China based on remote sensing

    This paper, taking Chagan lake as the study area, uses and improves MWR V1.0 (Rivers (Lake) Health Assessment Indicators, Standards and Methods V1.0) relating to the theory and method of physical structure integrity assessment. A 500 m × 1000 m grid on the lakeshore zone is a basic evaluation unit, and then a lakeshore physical structural integrity evaluation system using remote ...

  • Making it Work: The Application of Time as a Public Health Control in the Field

    Time as a public health control (TPHC) is increasingly being recognized as a viable alternative to temperature control for potentially hazardous foods in the developed world. This is reflected by recent changes to food regulations and other pertinent health legislation in both Canada and abroad. Considerable ambiguity remains, however, as to when and how TPHC should be applied at the field level. ...

  • Construction and Civil Infrastructures Monitoring Systems

    Civil infrastructures are usually monitored through its whole life cycle. SHM (Structural Health Monitoring) technologies enable the estimation of the structural state and detection of structural change that affects the performance of a structure. Two discriminating factors in SHM are the time-scale of the change (how quickly the state changes) and the severity of the change. These factors ...

  • Managing Environment, Health and Safety Risks at the National Museums of Kenya for Sustainability

    AbstractUrban environmental policy cannot escape the dictates of global environmental requirements as stipulated by the principles of Stockholm Conference, Rio-Summit, and the Johannesburg Summit that includes multilateral environmental agreements. The National Museum of Kenya (NMK) is a public, educational, scientific and heritage management institution established in 1909. It has undergone ...


  • Human health risk assessment of lead in drinking water: a case study from Port-au-Prince, Haiti

    In Latin America and the Caribbean (LAC), human intoxication to lead is considered as an important public health issue. In Port-au-Prince, concentrations of lead ranging from 40 ?g/L to 90 ?g/L, greater than the threshold value (10 ?g/L) for drinking water, were measured in groundwater and drinking water. This study aims to assess human health risks generated by exposure to lead in the ...
