The paper presents an innovative networked radar system for detection of obstacles in a railway level crossing scenario. This Monitoring System (MS) is able to detect moving or still obstacles within the railway level crossing area automatically, avoiding the need of human presence for surveillance. The MS is also connected to the National Railway Information and Signaling System to communicate...
The paper focusses on the impact dryland ecosystems of conflicting governance in regulations land use, water for irrigation and electric energy from photovoltaic installations (PV). research uses empirical results a panel data model based long time series that enable sensitivity main crops to cost viability solar system connected grid be identified. We present evidence private social benefits i...
At low temperatures, the magnetization of the molecular ferric wheel NaFe6 exhibits a step at a critical field B(c) due to a field-induced level crossing. By means of high-field torque magnetometry we observed a hysteretic behavior at the level crossing with a characteristic butterfly shape which is analyzed in terms of a dissipative two-level model. Several unusual features were found. The non...
