BOES: Building Occupancy Estimation System Using Sparse Ambient Vibration Monitoring
In this paper, we present a room-level building occupancy estimation system (BOES) utilizing low-resolution vibration sensors that are sparsely distributed. Many ubiquitous computing and building maintenance systems require fine-grained occupancy knowledge to enable occupant centric services and optimize space and energy utilization. The sensing infrastructure support for current occupancy esti...
متن کاملMonitoring a Building Using Deconvolution Interferometry. II: Ambient- Vibration Analysis
Application of deconvolution interferometry to earthquake data recorded inside a building is a powerful technique for monitoring parameters of the building, such as velocities of traveling waves, frequencies of normal modes, and intrinsic attenuation. In this study, we apply interferometry to ambient-vibration data, instead of using earthquake data, to monitor a building. The time continuity of...
متن کاملReal-time Monitoring of Structural Vibration using Spectral-domain Optical Coherence Tomography
we report in this paper the development of a spectral-domain optical coherence vibration tomography (OCVT) using a broadband CCD-based spectrometer and a shortcoherence white light source. We demonstrate that both the vibration amplitude and frequency can be quantified, in the frequency range of 0250 Hz, with an axial resolution of 1 m. Furthermore, the inner structure (layer thickness) of a ...
متن کاملStructural Identification of an 18-Story RC Building in Nepal Using Post-Earthquake Ambient Vibration and Lidar Data
Few studies have been conducted to systematically assess post-earthquake condition of structures using vibration measurements. This paper presents system identification and finite element (FE) modeling of an 18-story apartment building that was damaged during the 2015 Gorkha earthquake and its aftershocks in Nepal. In June 2015, a few months after the earthquake, the authors visited the buildin...
