Abstract: The importance of developing accurate seismic analysis for dams becomes crucial, especially in active seismic zones. In this research, a probabilistic seismic hazard analysis (PSHA) for 48 Spanish dams in the Andalusian ...

Abstract: Surveying technology as regards total stations (TS) has changed in the last fifty years. The original idea of measuring and storing polar coordinates has been progressively revolutionized by means of reflectorless distance ...

Abstract: Increasing nonstationarity increases the uncertainty of hydrological processes. Consequently, intrinsic randomness increases in magnitude and occurrence. In order to generate a reliable and robust predictive model, time ...

Abstract: This paper comprises the search of the optimal geometric parameters (area and volume) for double-arch dams. The approach is structured in several consecutive stages. The process begins with a definition of the problem about ...

Abstract: nvironmental measurements often show unsteady variability and background red noise (stochastic component) superimposed on persistent trivial daily, seasonal, and annual variability. In addition to this, environmental time ...

Abstract: Bunching at bus stops can be a major problem for traffic and passengers if bus arrivals are not well distributed. Arrivals can be better staggered if bus stops are divided into more than one berth. This article presents a ...

Abstract: This article proposes an optimization model for designing the intervals (headways) and sizes of buses circulating on public transport networks by minimizing the system’s operating and user costs. The proposed model takes ...

Abstract: Management practices of lean production within the last planner system (LPS) have enabled significant improvements in project performance worldwide. These improvements are, in part, attributed to practices that strengthen ...

Abstract: International standards establish strict criteria for the measurement of railway track geometric parameters by track inspection trolleys. In the case of the rails’ internal geometry, the values of some parameters (such as ...

Abstract: Torque influences the main phenomena that occur during friction stir welding (FSW) process. However, models for torque have received little attention. In this paper, inverse problem method is used to estimate the parameters ...
