This paper summarizes the results of experimental observations and measurements of beam-beam interactions in DAΦNE, the Frascati Phi-factory. The achieved results are reported with analysis of present limitations in both single and multibunch operation modes and compared with numerical simulations.
The Sensor Web provides access to observations and measurements through standardized interfaces defined by the Open Geospatial Consortium’s Sensor Web Enablement (SWE) initiative. While clients compliant to these standards have access to the generated sensor data, it remains partially hidden from other knowledge infrastructures building on higher-level W3C standards. To overcome this problem, i...
Present study examines turbulent structures of a rough bed open-channel flow in the context of deterministic approach. Instantaneous velocity field is measured in different hydraulic conditions using two dimensional Particle Image Velocimetry (PIV) in vertical plane and Stereoscopic PIV in horizontal plane. Different techniques and quantities such as swirl strength, two-point and cross-correlat...
