To solve the quick and accurate level-adjusting problem in the process of spacecraft precise mating, automatic leveling and equalizing hoist device for spacecraft is developed. Based on lifting point adjustment by utilizing XY-workbench, the leveling and equalizing controller by a self-adaptive control algorithm is proposed. By simulation analysis and lifting test using engineering prototype, v...

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...

Land leveling is one of the most important steps in soil preparation for consequent objectives.  Parallel policies need to take both energy and environmental subjects into the account as well as certain financial development and eco-friendly protection. Energy is one of the most important elements in agricultural sector. Nevertheless, pollution is linked with the usage of fossil fuels (particul...

Dialect loss is a relatively new but by now quite general phenomenon in Flanders (i.e., Dutch-speaking Belgium). Although the processes of dialect change and dialect loss have proceeded with great regional di¤erences in speed and intensity in the past decades, there is a general tendency toward replacing primary dialect features of a relatively local scope by secondary dialect features that hav...
