  • Structural Monitoring Inside a Copper Mine

    CAS DataLoggers recently supplied the intelligent datalogging solution for the operators of a copper mine. For the safety of both miners and machinery, it was essential that any potentially dangerous situations were identified early by closely monitoring the mine’s entire structure to detect ground movement or subsidence around the mine which could make the structure become unstable. A ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • 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 ...

  • 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 ...

  • GPR: a new tool for structural health monitoring of infrastructure

    Abstract Recent developments in acquisition methodology, data acquisition systems, post-processing software, and the availability of user friendly high-frequency antennas have enabled the GPR user to generate accurate three dimensional images of the interior of concrete structures. Four case studies are discussed with emphasis on output that is readily understood by the ...

  • 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 ...

  • 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 ...

  • Innovative contractual structures for inter-organisational systems

    This paper tests the principal-agent theory in the context of contracting practices for the development of large-scale engineering projects. Five hypotheses are derived from the principal-agent theory regarding the propensity to use behaviour-based contracts versus outcome-based contracts function of the project owner's risk aversion and monitoring competencies, of the goal congruence between ...

  • 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 ...

  • 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 ...

  • 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:  ...

     Purpose of Document The purpose of this document is to provide standardized procedures for California Integrated Waste Management Board (Board) inspectors to use when performing landfill gas (LFG) monitoring during routine disposal site inspections. The standardization of procedures is intended to produce an acceptable level of confidence in the monitoring. This document presumes that each ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
