According to the special requirements of Sheet Molding Compound (SMC) a set of quadrangular leveling system is designed, whose leveling precision is controlled by electro-hydraulic proportional technology. Based on analyzing the components and working principle of the quadrangular leveling system, the mathematical model of this system is established. The dynamic characteristics of stability and...

Although leveling is a very precise technique for geodetic deformation monitoring, it is quite expensive and timeconsuming. InSAR is a relatively new technique for precise deformation monitoring and has some important advantages compared to leveling: the high spatial resolution of the data and the relatively low costs of the technique. In this article both techniques are considered for the esti...

In project scheduling, many problems can arise when resource fluctuations are beyond acceptable limits. To overcome this, mathematical techniques have been developed for leveling resources. However, these produce a hard and inflexible approach in scheduling projects. The authors propose a simple resource leveling approach that can be used in scheduling projects with multi-mode execution activit...

Differential interferogram images derived from repeat-pass spaceborne Synthetic Aperture Radar (SAR) systems give the possibility to map surface deformations of small spatial extent and to monitor their spatiotemporal evolution. A slow and local phenomenon of subsidence caused by underground coal mining has been observed near Gardanne, France, from images acquired by both European ERS-1/2 satel...

Shoreline change was identified as a vital sign for the Southwest Alaska Monitoring Network because land loss or gain at the marine edge has important ecological and jurisdictional implications to resource managers of coastal National Parks. To evaluate the type of shoreline changes occurring along the 82 km coastline of Lake Clark National Park and Preserve, 7 of 10 cross-shore beach profiles ...

Abstract Laser-controlled land leveling (LLL) can help improve rice production's spatial and temporal management, leading to optimized water crop management. This research resulted in sustainable performance indicators illustrate that LLL is a technology for production. The assessment was conducted Cambodia, the Philippines, Thailand, Vietnam, India. Benefits of include saving use, water, agron...
