This paper presents a hierarchical approach to network construction and time series estimation in persistent scatterer interferometry (PSI) for deformation analysis using the time series of high-resolution satellite SAR images. To balance between computational efficiency and solution accuracy, a dividing and conquering algorithm (i.e., two levels of PS networking and solution) is proposed for e...

many new technologies have been employed to improve welfare conditions and to provide an optimum utilization of the existing resources in agriculture sector. laser leveling technology is one of the most progressed in maintenance of soil and water resources which itself has an important role in sustainable development. the purpose of this study was to realize the specifications of adopters vs. n...

The application of conventional leveling approaches is limited to large scale production. This paper presents a systematic procedure for leveling of low volume and high mix production. It employs clustering techniques to group product types into product families. After that, a family-based leveling pattern is created which describes a repetitive sequence of capacity slots considering all famili...

Focused on revealing variations of dynamic characteristics of an auto-leveling system used in mobile elevating work platforms (MEWP) at large height, a unified mathematical model composited of a series of sub-models was built for the leveling systems. An effect on dynamic characteristics including the fast response and relative stability from varying-parameters was investigated. Results display...

Production leveling is an essential element of the Toyota Production System. It aims at balancing production volume as well as production mix to reduce waste, overburden, and unevenness. The application of conventional leveling approaches is limited by the requested product diversity. Because of this production leveling is predominantly used in high volume production. Nevertheless it can be imp...

The Ordos Block in China experiences tectonic activity and frequent earthquakes due to compression from the Tibetan Plateau extension North Block. This has prompted construction of a high-resolution three-dimensional (3D) deformation field better understand region’s crustal movement. Considering limitations existing geodetic observations, we used InSAR, GPS, leveling observations create high-pr...

Leveling is a mechanism that restores or imposes uniformity on paradigms, thereby upholding the principle “one meaning one form” (Humboldt’s Universal). In a set of inflectionally-related forms, the shared element is the verb stem, whose meaning is constant across all forms. The principle of onemeaning-one-form is contravened whenever a stem alternation arises as the result of a phonological pr...

We present results on the leveling of polymer microdroplets on thin films prepared from the same material. In particular, we explore the crossover from a droplet spreading on an infinitesimally thin film (Tanner's law regime) to that of a droplet leveling on a film thicker than the droplet itself. In both regimes, the droplet's excess surface area decreases towards the equilibrium configuration...
