GTm_R modelGNSS meteorologyPrecipitable waterAtmospheric weighted mean temperature, T-m, is a key parameter in ground-based GNSS precipitable water (PW) retrieval, especially for a real-time mode. Considering the seasonal variability of the T-m vertical gradient across the globe, a global grid-...
互联网 Existing clustering algorithms can be generally categorized into 5 classes: partitioning, hierarchical, density - based, grid - based, and model - based. 现有的聚类算法可以分为5类:分 割算法, 分层算法, 基于密度算法,基于网格算法, 以及基于建模的算法. ...

In addition to supply and demand, grid-based MES models must consider the energy flows in the networks, energy storage and the energy conversion between networks. Two approaches are used to model such systems: the integrated approach and model linkage or co-simulation. In the integrated approach,...
In this example, you used a "constant-velocity" model with the tracker. This motion model assumes that the targets move at a constant velocity, meaning constant speed and direction. However, in urban scenes, this assumption is usually not accurate. To compensate for the unknown acceleratio...

To demonstrate the capability of our multiphase flow model for the water impact of the complex body, the water entry of a multihull section similar to the catamaran is simulated. The geometrical shape and dimensions of the multihull are shown in Fig. 11, and the multihull surface is describe...
Promising results have been reported for supervised approaches, but many training samples are needed to precisely model the feature distribution to final target classes. These supervised methods are also subject to training sample collection and machine learning adoption. For this reason, many attempts ...
