MULTI-AGENT SOURCE LOCALIZATION USING PASSIVE SENSING
… communication and rely solely on agent's passive sensing. The first source localization algorithm is composed of static individualistic and social behaviours. The individualistic behaviour is inspired from a bacterium's random walk while performing chemotaxis and is self-sufficient in …

Passive sensing of user behavior and Well-being at home
… behavior in their homes is central to health sensing, behavioral research, and building smarter environments. In this thesis, we explore learning such information in a passive and contactless manner - without asking people to wear sensors on their bodies or change the way they normally live. …

Dynamics of Multi-Agent Systems with Bio-Inspired Active and Passive Sensing
… information from its reflection. In contrast, passive sensors such as cameras and microphones rely on the signals emitted from the environment. In the current application of active sensors in multi-agent autonomous systems, agents only rely on their own active sensing and filter out any …
