PLC Plant Process Remote Monitoring And User Friendly Gui Using Labview

This project focused on the development of PLC remote monitoring software to control and remotely monitor a pick and place loader. Object Linking and Embedding for Process Control (OPC) is used as a standard interface between programmable logic controller (PLC) and LabVIEW’s remote monitoring application

Marquette Interchange Phase I Final Report

This report provides details on the design, installation and monitoring of a pavement instrumentation system for the analysis of load-induced stresses and strains within a perpetual HMA pavement system. The HMA pavement was constructed as part of an urban highway improvement project in the City of Milwaukee, Wisconsin. The outer wheel path of the outside lane was instrumented with asphalt strain sensors, base and subgrade pressure sensors, subgrade moisture and temperature sensors, HMA layer temperature sensors, traffic wander strips and a weigh in motion system. Environmental sensors for air temperature, wind speed and solar radiation are also included. The system captures the pavement response from each axle loading and transmits the data through a wireless link to a resident database at Marquette University. The collected data will be used to estimate the fatigue life of the perpetual HMA pavement and to modify, as necessary, pavement design procedures used within the State of Wisconsin

Diverse perceptions of smart spaces

This is the era of smart technology and of ‘smart’ as a meme, so we have run three workshops to examine the ‘smart’ meme and the exploitation of smart environments. The literature relating to smart spaces focuses primarily on technologies and their capabilities. Our three workshops demonstrated that we require a stronger user focus if we are advantageously to exploit spaces ascribed as smart: we examined the concept of smartness from a variety of perspectives, in collaboration with a broad range of contributors. We have prepared this monograph mainly to report on the third workshop, held at Bournemouth University in April 2012, but do also consider the lessons learned from all three. We conclude with a roadmap for a fourth (and final) workshop, which is intended to emphasise the overarching importance of the humans using the spac

Innovative technologies for restoration in Pompeii. The 3D morphometric survey in via dell’Abbondanza

The project had as primary objectives the safeguarding of architectural remains and the experimentation with restoration methodologies and materials. The restoration works addressed a number of facades along the stretch of the Decumanus Maximus known today as via dell'Abbondanza. After the collection of numerous notes from previous archaeological investigations and from visual inspections about architectural morphology, materials and state of conservation, surveys of ancient facades were carried out and measurement data were collected. The survey by means of 3D laser scanner of the varied and complex architectures have been characterized by an attempt to focus efforts on contributing representational knowledge of the existing site elements

THE NEED FOR 3D LASER SCANNING DOCUMENTATION FOR SELECT NIGERIA CULTURAL HERITAGE SITES

Heritage sites documentation with 3D laser scanning has proven to be great way of preserving information and narratives about these sites in a very detailed and complete style to facilitate reconstruction if, peradventure, their significant part is lost to natural or man-made disaster. This spatial information forms not only an accurate record of rapidly deteriorating sites, which should be saved for posterity, but also provides a comprehensive base dataset by which heritage site managers, archaeologists and conservators can monitor and perform necessary restoration work to ensure physical integrity of cultural sites. In the past, traditional methods of documentation such as direct hand measurement and drawing at the point of capture have been used for documentation in West Africa heritage sites, for example Nigeria. These methods are not only time consuming but prone to several and large scale error especially when it requires high density point capture. This paper suggests way of documentation that will provide accurate data in shorter duration of time, especially for heritage structures with irregular and unmarked geometrical details, by using 3D laser scanning technology. This technology can produce detailed 3D model, two-dimensional (2D) drawing, and a guide to preservation and virtual reconstruction of heritage sites

Analysis on the Appropriate Buried Depth of the Cold-proof Drainage Hole of the Tunnel in the Cold Region

A cold-proof drainage hole is an effective measure to prevent freezing injury of a tunnel in a cold region. However, the construction technology and insulation effect of the cold-proof drainage hole only focused on existing research. This study used MIDAS/GTS for modelling based on a tunnel in cold region of Qinghai Province, China to determine the suitable buried depth of a cold-proof drainage tunnel from the mechanical properties and variation of deformation of tunnel in cold region. The working conditions of first excavating the main tunnel and then the cold-proof drainage hole were set. The variation rules of displacement, stress, and plastic zone of the main tunnel and the cold-proof drainage hole under different buried depths were analyzed. The interaction mechanism between the main tunnel and the cold-proof drainage tunnel under different buried depths was revealed. Results show that: the structure of main tunnel hole is interplayed with that of cold-proof drainage hole; from the point of displacement change rule, the optimal effective buried depth for cold-proof drainage hole of a tunnel in China\u27s Qinghai Province is from 5 m to 6 m; from the point of stress change rule, the optimal effective buried depth for the cold-proof drainage hole is also from 5 m to 6 m; from the point of plastic zone change rule, the optimal effective buried depth for the cold-proof drainage hole is from 4 m to 6 m considering the stress uniformity of support and material for cold-proof drainage hole. The effective buried depth of the cold-proof drainage hole is confirmed to be 5 m. The results of finite element analysis are consistent with the field monitoring results, thereby verifying the reliability of the analytical results in this study. This study has guiding significance for the construction of the cold-proof drainage tunnel in the cold region

Developing an Automated System for Checking the Strut Arrangement in Deep Excavation

At the early stage of the project, the clash problem in the strut arrangement was reviewed by using two-dimensional construction drawings. This practice was time-consuming and error-prone. Moreover, some 3D construction software could detect clashes between the structural strut and permanent building structures. But they were still limited in this arrangement including (1) decision of strut arrangement relying on human judgment; (2) unable to distinguish between unreal clash and real clash in the strut arrangement based on work practice, and (3) unable to present overview of all clash detections from each strut at one time. To solve these problems, this paper integrated rule-based approach with Building Information Modelling (BIM) to develop an automated system for detecting and solving clashes of the structural strut. The methodology primarily developed three main modules of an automated system by using rule-based approach. Then, these modules applied with BIM software, visual programming and spreadsheet for generating, checking and solving the clashes. To proof the efficiency, a case study of office basement construction was applied to test the system. As a result, this system could improve the strut arrangement work by reducing the human judgement. Moreover, the system has shortened the time of the strut arrangement by only specifying on the real clash problems. Last, this system also could provide better visualization of clashes
