Privacy-Aware Object Representation for Surveillance Systems

Abstract Real-time object tracking, feature assessment and classification based on video are enabling technologies for improving situation awareness of human operators as well as for automated recognition of critical situations. To bridge the gap between video signal-processing output and spatio-temporal analysis of object behavior at the semantic level, a generic and sensor-independent object representation is [...]


Becoming a Measuring Instrument

Abstract This article provides an ethnographic examination of olfactory consumer testing in the perfume industry. What kind of reality is generated within such practices? The analysis is focused on one particular testing method used in order to assess the hedonic performance of fine fragrances. The authors observe what happens inside the testing venue. The article [...]


A brief history of measurement

Abstract The aim of this paper is to situate the subject of measurement and metrology in its historical and philosophical context. Everyone agrees that the numeration of objects and the quantification of the characteristics of some simple systems are very ancient practices encountered in any specific civilisation. Indeed the link between measurement and numeration comes [...]


Ambient Intelligence at the Beach

Abstract  We describe an experimental public resource monitoring system that combines sensor data and human input to create a new descriptor of ambient water conditions. We call this new metric the swimming pleasure measure. We give an overview of how it is composed, how it relates to existing public water health monitoring efforts and how [...]


Power Grids as Complex Networks. Typology and Fragility

Abstract We almost certainly agree that the harnessing of electricity can be considered the most important technological advance of the twentieth century. The development that allows this control is the power grid, an intricate system composed of generators, substations and transformers connected by cable lines hundreds of kilometers long. Its presence is nowadays so intertwined [...]


A Survey of Technical Requirements and Consumer Application Standards for IP-based Smart Grid AMI Network

Abstract The smart grid is a new advanced electrical network promoted by the government to address environmental sustainability, energy generation, distribution and consumption efficiency issues. As one of the enabling technologies, Advanced Metering Infrastructure refers to systems which measure, collect and analyze energy usage, and interact with advanced devices such as smart meters through various [...]


Understanding and Using Rendezvous to Enhance Mobile Crowdsourcing Applications

Abstract Researchers are exploring the rendezvous concept—bringing sensors close to one another in space or time—as a way to make sense of disparate data collected by individuals. Applications such as participatory atmospheric sensing illustrate the potential of rendezvous to help create powerful mobile applications. Comments This paper describes an attempt to use web and mobile technologies [...]


A Sensing Architecture for Mutual User-Environment Awareness Case of Study: A Mobility Aid for the Visually Impaired

Abstract In this paper, a platform to manage user-environment interaction is addressed. The core of the methodology consists of a continuous communication between a sensing module hosted on the user and a sensor network distributed in the environment. Such strategy provide the cognitive system with a continuous perception of both the environment and the user. [...]


Cognitive Diversity Sensing

Abstract Radar sensing is and will continue to have great importance in both the civil and military communities. This importance will increase in proportion to the tasks that radar is able to reliably carry out. New methodologies and new technical capabilities offer the potential for new functionality and improvements in existing ones. Radar is currently going [...]


Wearables in the Workplace: Sensing Interactions at the Office

Abstract Wearable computers such as PDAs and cell phones are prolferating in organizations. This paper introduces a methodology for leveraging this wearable infrastructure to provide isight to the undelying social dynamics of an organization. The work lays a foundation what will enable a variety of applications, from knowledge management to organizational simulation. Comments This paper [...]
