Monitoring and Forecasting in Construction Projects Using Time Buffer
Abstract: The key to project management is effective performance monitoring and forecasting. The existing methods using input- output cash flow, earned value, etc. do not differentiate between work done on the critical path and work done on non-critical paths. Such methods mask the real situation and mislead the project team because progress on one path often compensate for the delay in other. The paper proposes a more effective method to facilitate …

Method of Analysis for Chloride Distribution in Concrete from Torrent Data
Abstract: Design w/c ratio becomes less important than achieved cover performance in the case of existing structure. Therefore, inspection data of chloride profile from some real structures do not always obey the rule of Fick’s law, suggesting the influence of a new parameter. In this study, chloride ion profiles and behavior of penetrating water for normal, fly ash and slag concrete with w/c ratio as 40, 55, and 70%, respectively, cast …

Probabilistic Sensitivity Analysis of Cover Quantity and Quality of Reinforced Concrete Structures
Abstract: Design procedures based on current specifications do not always ensure required service life, mostly due to the environmental effect, error at the time of construction and underestimated cover properties at the time of design. Moreover, single-point value of any property does not provide rational support to the decision maker. Statistical resampling technique for each of the cover properties used to find out the service life of the structures is thus …

Using digital holographic interferometry to monitor symmetrical temperature fields in liquids and an interference technique for simultaneous heat and mass transfer
Abstract: In this work, we offer a technique for off-axis digital holographic interferometry to measure dynamic temperature change quantitatively in real-time and visualise volumetric temperature fields formed by a 2D axial-symmetric heated fluid from a pulsatile jet in a water tank. For the experimental examination, a portable Mach-Zehnder interferometer was constructed. The pulsatile jet was supplied with hotter water and submerged in a tank of water. Results that have been averaged, …

Data Driven Controller Design For Distributed Power Sources In Microgrid
Abstract: AbstractUsing renewable power sources requires controlled procedures to accomplish satisfactory stabile levels of power transmission and keep up with grid power deviation. Additionally, these methodologies in a perfect world require no pre-information of the grid structure, and as meagre correspondence with neighbouring power sources as would be prudent. As a next stride, we concentrate on how the power can be dispatched from different power hotspots for enhanced grid productivity. Microgrids …
