Development of a Weatherproof Windscreen for a Microphone Array
Microphone windscreens are typically used to reduce the noise associated with wind flowing over a microphone diaphragm by reducing the velocity of the airflow. While most windscreens are effective at reducing this noise, they do not protect the microphone from many natural elements, such as …

An Approach for Conducting Stakeholder Interviews for a Novel Technology, as applied to the Locomotive Industry
… head up display” (AR-HUD). The goal is to use a windscreen mounted transparent display to provide a wide field-of-view while maintaining AR conformality using image-based head tracking. Stakeholders have different backgrounds and expectations, so solicitation and evaluation of opinions is …

Minori rumeni tra percorsi migratori e rappresentazioni. Nè soli, nè accompagnati a Bologna
… teenagers engaged in Bologna in activities like windscreen washing, pocket-picking, begging and street prostitution. The aim of the research was to gain access to their daily life, to observe their relationship with the adults who “accompany” them and the strategies they activate in order to take …

Optimization Of Wind Fence Enclosures For Infrasonic Wind Noise Reduction
A large porous wind barrier enclosure has been built and tested to optimize wind noise reduction at infrasonic frequencies between 0.01-10 Hz in order to develop a technology that is simple, cost effective, and improves upon the limitations of pipe and porous hose arrays. The effects of varying the …
