ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry

ABSTRACT Exhaustive long‐term and large‐scale ice jam records are scarce in most cold river environments. Many discrete events occur in small, sparsely populated river systems and are poorly represented in open‐source databases. These observation biases are transferred to predictive models of ice jams and the collective understanding of their formation

Design of a low noise amplier for a X-band phased array radar system in SiGe BiCMOS technology
A LNA is the first active stage of a radio frequency receiver module, with the prevalent goal of minimizing the noise figure of the whole system. This work presents the design of two narrow-band LNA and a wide-band LNA for phased array radar applications.

In order to increase telecommunication data rates and enhance the precision and range of modern radar systems, improving the noise factor of a communication link has become crucial. As demonstrated by the FRIIS formula, the noise factor of a reception architecture is mainly determined by the noise factor of the first stage.

ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...
