  • Design of a biomimetic-based monitoring and diagnostic system for civil structures

    Recent high intensity natural events such as hurricanes, tsunamis, and earthquakes have introduced new challenges for the design, maintenance, and sustainability of civil structures. Globally, civil infrastructures are deteriorating at an alarming rate caused by overuse, overloading, aging, damage or failure due to natural or man-made hazards. With such a vast network of deteriorating ...

  • Performance of damage detection algorithms for health monitoring of joints in steel frame structures using vibration–based techniques

    Steel frame structures are widely used for industrial buildings, bridges, off–shore structures, etc., due to their high reliability and less construction time. In these types of structures, beams and columns are often connected by welding or fasteners forming rigid joints. In this study, viability of several damage detection algorithms for health monitoring of joints in planar frame structures ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Application of nanocrystalline metal oxide gas sensors for air quality monitoring

    Increasing concern regarding health effects caused by air pollution, together with the limited spatial resolution achievable with conventional monitoring stations, have driven efforts to develop inexpensive metal oxide gas sensors for air quality measurements. The sensing mechanism is dependent on physicochemical reactions between adsorbed gas molecules and oxygen species on the oxide surface, ...

  • Occupation-specific screening for future sickness absence: criterion validity of the trucker strain monitor (TSM)

    Background: Monitoring psychological job strain may help occupational physicians to take preventive action at the appropriate time. For this purpose, the 10-item trucker strain monitor (TSM) assessing work-related fatigue and sleeping problems in truck drivers was developed. Objectives: This study examined (1) test–retest reliability, (2) criterion validity of the TSM with respect to future ...

  • Neon Gas and Where it is Used - PureAire Oxygen Deficiency Monitors for Safety and Why a Monitor May be Required?

    Neon gas has a range of uses in industry, including in the popular business signs advertising stores as open. Explore some of the less well-known ways to use neon and learn how use of the gas may require installation of an oxygen deficiency monitor to protect worker safety.   Uses for Neon Gas Neon gas can be filtered from helium using ...

  • Gas Monitoring for Ventilation Control and Energy Management

    The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

  • Construction site health and safety failures

    As what is largely agreed to be the world’s most dangerous industry, construction site Health and Safety failures constitute potentially severe harm to worker wellbeing, with the capacity to severely impact quality of life or – put bluntly – end it. Running contrary to this doom-laden approach though, improvements to the industry typically arise from assessing ...

  • Cyanobacteria successfully monitored and controlled by using ultrasound

    Cyanobacteria- also known as blue-green algae- cause problems when blooming in lakes, ponds and reservoirs. Mainly due to the production of toxins, cyanobacteria cause fish kill and the death of other aquatic animals. They also affect human beings, causing paralysis and skin irritation, and they are even thought to be related to the occurrence of liver cancer. In drinking water reservoirs, the ...

  • Forensic engineering for machine foundations

    Machine foundations are dynamically loaded structures whose response depends on a number of parameters such as strength, stiffness, mass, damping, soil–structure interaction and fatigue. Performance–based designs and evaluation procedures are gaining popularity particularly with respect to structures that have been built using codal provisions existing a few decades back. Enhancement of knowledge ...

  • Gas analysers support management of Swindon fire

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency ...

  • Improving service delivery of water, sanitation, and hygiene in primary schools: a cluster-randomized trial in western Kenya

    Water, sanitation, and hygiene (WASH) programs in schools have been shown to improve health and reduce absence. In resource-poor settings, barriers such as inadequate budgets, lack of oversight, and competing priorities limit effective and sustained WASH service delivery in schools. We employed a cluster-randomized trial to examine if schools could improve WASH conditions within existing ...
