A computational methodology dedicated to embankment dam performance assessment has been designed and implemented. The model’s inputs are the whole set of available information and data: visual observations, monitoring measurements, calculated data and documents related to design and construction processes. Firstly, a formal grid is proposed to structure the inputs. It is composed of six fields:...

Firstly, the concept of digital reservoir is proposed and discussed in the paper, then the method how to monitor dam’s state by digital means and how to transmit the monitoring data by GPRS technology is presented, and the method can monitor the dam’s state in real time and its advantages such as real-time, visibility, visualization are analyzed later. The indicators reflecting the safety of da...

Pervasiveness of location acquisition technologies such as GPS, GSM, and Wi-Fi are growing swiftly. This opens the doors to use these technologies for ease and advancement in the lives of human. Human daily routine trajectory activities like visiting different places (e.g., Office, Restaurant, and Sports Club) for performing particular tasks have significant impacts on life. In this paper, we p...

Usually, dam monitoring systems are based on both boundary conditions (temperature, rainfall, water level, etc.) and structural responses (displacements, rotations, pore pressures, etc.). Statistical analysis tools are widely used to compare the current response of the dam with a whole set of recorded data, in order to determine eventual unwanted behaviors. The main drawback of this approach is...

This paper presents the application of Parallel Small Baseline Subset (P-SBAS) algorithm, provided by Geohazards Exploitation Platform for precise monitoring an earth dam's ground deformation using C-band Sentinel-1 data. The test site object this study was Kramis dam, located in Mostaganem State, Western Algeria. Among multiple advanced DInSAR techniques, SBAS is very adequate long-term displa...

OBJECTIVES The aim of this study was to assess technical preferences of general dental practitioners when restoring anterior composite restorations. How the level of clinical experience or post-graduate training infuenced their options was also tested. MATERIAL AND METHODS A cross-sectional study was performed using a questionnaire with general dental practitioners (GDPs) (n=276) in Southern ...

The regime of sediment transport in the Jingjiang Reach has significantly changed from quasi-equilibrium to sub-saturation since the impoundment of the Three Gorges Dam (TGD), and vertical profiles of suspended sediment concentration (SSC) have changed accordingly. Vertical profiles of SSC data measured at three hydrological stations in the Jingjiang Reach (Zhicheng, Shaishi, and Jianli), befor...
