In this paper we present our approach and experiments with equipping a mobile robot with a novel MEMS angular rate sensor (gyroscope) that was originally developed for automotive usage and is therefore mass produced and very low priced. By fusing its measurement results with data obtained from other cheap sources, it is feasible to use this sensor for continuous tracking although it is still af...

Hydromagnetic flow and mass transfer of a viscous incompressible fluid over a microcantilever sensor surface are studied in the presence of slip flow. In addition, chemical reaction at the sensor surface is taken into account. The governing equations for the flow are reduced to a local nonsimilarity form. Resulting equations are solved numerically for various values of flow parameters. Effects ...

Inexpensive aerosol sensors have been considered as a complementary option to address the issue of expensive but low spatial coverage air quality monitoring networks. However, the accuracy and response characteristics of these sensors is poorly documented. In this study, inexpensive Shinyei PPD42NS and PPD60PV sensors were evaluated using a novel laboratory evaluation method. A continuously cha...

T he tragic events of September 11 underscored beyond a shadow of doubt that America is no longer invulnerable to large-scale terrorist attack, and the investigations since conducted into the nature of the threat have unveiled essentially limitless possibilities for more to come. The potential introduction of weapons of mass destruction into such a scenario only furthers the ability of a small ...

Our system is designed to cope with water depths of around 100m, meaning the number of measurements taken during one dive can be significant. Storage is thus required for the large volumes of measurement data: not only those collected by the diving unit but also from light and acceleration sensors placed on the top of the buoy. System data also needs to be saved; for example, the energy produce...

In order to maximize road maintenance funds and optimize the condition of road networks, pavement management systems need detailed and reliable data on the status of the road network. To date, reliable crack and raveling data has proven difficult and expensive to obtain. To solve this problem, over the last 10 years[1][2] Pavemetrics inc. in collaboration with INO (National Optics Institute of ...
