An autonomous system needs “active sensing” to decide which combination of action and sensing is expected to give the largest increase in information. This paper deduces the intrinsic properties of information and sensor processing from first principles, and combines them to define active sensing in a coordinate-free way. Intrinsic properties don’t depend on the choice of coordinates, reference...

In previous studies, active suspension system in conventional powertrain systems was investigated. This paper presents the application of active suspension system in parallel hybrid electric vehicles as a novel idea. The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...

Embedded sensing systems are pervasively used in lifeand security-critical systems such as those found in airplanes, automobiles, and healthcare. Traditional security mechanisms for these sensors focus on data encryption and other post-processing techniques, but the sensors themselves often remain vulnerable to attacks in the physical/analog domain. If an adversary manipulates a physical/analog...

Legume-nodulating bacteria (rhizobia) usually produce N-acyl homoserine lactones, which regulate the induction of gene expression in a quorum-sensing (or population-density)-dependent manner. There is significant diversity in the types of quorum-sensing regulatory systems that are present in different rhizobia and no two independent isolates worked on in detail have the same complement of quoru...

Rodents demonstrate an outstanding capability of texture discrimination and shape recognition with their whiskers (vibrissae). Many neurophysiological and behavioural studies reported that active whisking plays a critical role on tactile perception. However, the role and limitation of passive sensing has not been studied in detail. In this paper, we compare passive sensing and active sensing fo...

In order to realize an autonomous nuclear power plant, the sensing system performing daily inspection inside of the plant is indispensable. For the sensing system, reliability and exibility are demanded to cope with risky and complicated environments. In order to build such sensing system, we have been emphasizing the importance of cooperation and active control of various sensing functions, an...

This paper describes a methodology for modelling light pollution using geographical information systems (GIS) and remote sensing (RS) technology. The proposed approach attempts to address the issue of environmental assessment in sensitive suburban areas. The modern way of life in developing countries is conductive to environmental degradation in urban and suburban areas. One specific parameter ...

The aim of the present study was to identify geographical areas and time periods of potential clusters of dengue cases based on ecological, socio-economic and demographic factors in northern Sri Lanka from January 2010 to December 2013. Remote sensing (RS) was used to develop an index comprising rainfall, humidity and temperature data. Remote sensing data gathered by the AVNIR-2 instrument onbo...
