Processing of the Data Obtained with the Advanced Doppler Velocymeter

We present data obtained after a 2 years period of monitoring the wave’s parameters in an off-shore location. We have used the location of a working petroleum platform situated at: N44031’, E29034’ at 50 km from land and 80 km NE from Constanta Harbor, in the Romanian Black Sea waters. We describe monitoring systems used.and their solution. The Advanced Doppler Velocymeter (ADV) for parameters of marine waves is based on Doppler effect and it is composed of a transmitter at a frequency of 10 MHz and of 3 receivers which are equidistant from 1200. Data storage on the HDD PC, with the possibility of take-over and normal review (ASCII file). We can get the values of the speed and current division marine tide amplitude and direction of the wave at each measurement, the number of measurements, date, hour, minute and second of measurement, as well as other parameters, both as numeric values and a graph having abscissa registration number. This monitoring, which comprises the period of one year including, reveals an amplitude an annual average of the wave of hmed=1.53 m, obtained by taking maximum envelope appeared in a measurement range of 120 seconds. We compare these off-shore values with the coastal ones and we conclude that the wave’s energetic off-shore potential is unexpectedly bigger that in the coastal region.

Research on Calculation of Molecular Connectivity Index

Compared to other topological indices, molecular connectivity index has good structural selectivity and correlation.According to the molecule’s 2D and 3D topology file, we conducted research on the mol2 format file to consider how to convert the ASCII file into the adjacency matrix. Based on the adjacency matrix, we analyzed the relevant algorithm to calculate the molecules’ molecular connectivity index through adjacency matrix. As a molecular descriptor, the molecular connectivity index can be used in QSAR.

Post simulation visualization model for effective scheduling of modular building construction1This paper is one of a selection of papers in this Special Issue on Construction Engineering and Management.

The factory-based modular construction process has proven to increase the speed of construction, and improve quality and safety, while providing value to the customer and a rapid return on investment to the builder and owner. However, onsite module assembly creates new schedule demands, as activities are scheduled on a minute-by-minute basis; therefore simulation of the process becomes essential at early stages of a project. Although simulation proves to be an effective tool for project engineers to assess complex construction operations, it remains a symbolic base model with no visual link to the actual physical shape and look of the project’s activities. This paper presents the application of integrated simulation and post simulation visualization as a tool to assist the modular construction industry in scheduling onsite installation of prefabricated modules. The proposed methodology uses simulation model output as an ASCII file in a binary format and imports this ASCII file to 3D Studio Max to perform the animation. The output from the high level simulation model is transformed into frames/second in 3D Studio Max. The proposed methodology was tested on the planned construction of a 34-storey building in Brooklyn, New York, USA. Simulation visualization of the process proved to be effective in communicating the value and simplicity of a minute-by-minute schedule. Based on the output information, the most efficient solutions were generated. The use of post simulation visualization was effective in analyzing the construction methods of the case study which consisted of 950 structural steel modules. Issues related to construction activities’ productivity were synchronized to achieve onsite installation of the project in only 56 working days.
