  • Monitoring and control of CO emissions in parking structures

    Until recent years most parking garage owners and managers did not realize the detrimental effects that carbon monoxide emissions from motor vehicles have on the air quality inside parking garages. With increasing awareness of indoor air quality, astute parking garage owners and managers place great importance on the reduction of CO in parking garages. Ventilation systems are a must for today's ...

  • 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 ...

  • 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 ...

  • Fibre optic sensors as a non–destructive tool for structural monitoring

    Structural monitoring is a diagnostic tool for detection of defects/damages and for scheduling maintenance operations. It is essential to determine the safety of the structures by Non–Destructive Testing (NDT) for evaluation of strength/integrity. This assessment is required for the repair, rehabilitation and life extension of the structure. Fibre Optic Sensors (FOS) are attractive sensing ...

  • 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 ...

  • GW monitoring in saxony

    Background During the hundred-year flood in 2002 in Eastern Germany the river “Elbe“ and a lot of rivers in the catchment area exceeded the banks and caused damages of millions within a short period of time. Often unnoticed, the groundwater level was rising extremely after a certain time. The time of rising groundwater took considerably longer than the actual flood, and caused enormous ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...

  • Staying Safe with Environmental Monitoring

    Geotechnical Instrumentation involves administering the earth and environment and it is hence that designers have made different frameworks to make the occupation simpler. These frameworks grab thousands upon much information that it orders and illuminates so they can concoct evidence. The places where it is necessary are the pollution chance appraisal, trends in time and space; anticipatory ...

  • Dam Monitoring During Construction

    Intelligent Geo Data Logger Reads Vibrating Wire Sensors for Dam Monitoring  A hydroelectric dam under construction in Serbia required dam monitoring of several environmental and structural properties to guarantee long-term strength and stability. Therefore the dam’s construction engineers put forth a proposal for a large number of geotechnical sensors to be installed and used ...

    TenCate GeoDetect is the first sensor enabled geotextile on the market to provide soil reinforcement, structural health monitoring and an early warning system into one package. Our “intelligent geotextile” is the first system designed specifically for geotechnical applications and offers a technical solution for monitoring geo-structures for changes in strain, temperature or the ...

  • 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 ...

  • Understanding and Monitoring Hydrocarbons in Water

  • Monitoring of water node in wroclaw

    Background Wroclaw's water node has complicated structure. The river Odra has 3 main riverbeds and a lot of channels which are located in the centre of town. There are almost 100 hydro buildings which control flow of the water through the city and protect it against theflood. The great flood in 1997 proved that no one has control over it. Communication systems failure caused ...

  • 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 ...

  • Know About Tunnel and Environmental Monitoring

    Building a house may take a few months. Someone who has ever supervised the construction of a house must be aware that there are so many activities which are done for it. Now, think about the large construction projects. The roads, flyovers, railway tracks etc. we use today are result of rigorous hard work and planning undertaken by different construction companies. A large number of decisions ...

  • 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 ...

  • Pollutant monitoring in sludge treatment wetlands

    Phragmites australis for sludge dewatering and stabilization processes have been widely proved. The presence of reeds, indeed, efficiently allows solids dewatering and organic matter stabilization in order to obtain a stabilised product that can be suitable for land application, even if its environmental impact has to be considered. The actual revision of the European Union's Working Document on ...
