New surface acoustic wave gas sensor of the mass-sensitive type sensitive to the thermal properties of gasesSENSORS, 2002 IEEE - Tập 1 - Trang 372-375 vol.1
The basic principles of a new surface acoustic wave (SAW) gas sensor are described. Being essentially a sensor of the mass-sensitive type, the proposed device possesses certain features of the thermometric SAW sensors and is not only sensitive to the vapors of volatile substances, but capable of detecting gases by their thermal properties as well. This principles consists of making a certain delay...... hiện toàn bộ

Temperature dependences of fibre-optical sensors of mechanical valuesProceedings. 3rd Annual Siberian Russian Workshop on Electron Devices and Materials - Tập 1 - Trang 3 pp. - 2002
In the work the temperature dependences of the fibre-optical sensor of mechanical values are explored. The examinations of influence of temperature changes on the transmitting characteristic of FOS were spend. As a sensing device the silicon membrane with width h1=40 micron with strong centre by width h3=200 micron was used. The measuring were spend at temperatures T1=20/spl deg/C, T2=60/spl deg/C...... hiện toàn bộ

Shoreline feature extraction from remotely-sensed imageryIEEE International Geoscience and Remote Sensing Symposium - Tập 6 - Trang 3417-3419 vol.6
Different methods of delineation were used to extract shoreline features from images with different spatial and spectral resolutions acquired by airborne and spaceborne sensors. The exact location of the shoreline is difficult to obtain from the images and therefore the definition of shoreline was based upon the geomorphological and oceanographic characteristics of the area of study. Extracted sho...... hiện toàn bộ

The investigation of an integrated gas sensor arraySENSORS, 2002 IEEE - Tập 1 - Trang 343 vol.1
A micro integrated gas sensor array has been designed and fabricated with surface micro-machining technology. The sensor array consists of four elements integrated on a chip. Two different kinds of SnO/sub 2/ film were sputtered on the four sensors. Au and Pt were deposited on the surface of SnO/sub 2/ film as catalysts. The four sensors can be independently controlled by separate heater and tempe...... hiện toàn bộ

Fast data association algorithmProceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 3 - Trang 2167-2170 vol.3
The static problem of associating measurements from three bearing-only sensors in the presence of clutter, missed detection, and an unknown number of targets is presented in this paper. The main feature of our algorithm is to estimate the target location via the intensity of space intersection. This data association algorithm has been compared with some classical methods.

Upcoming naval space missions for remote sensing of the oceans, atmosphere and spaceIEEE International Geoscience and Remote Sensing Symposium - Tập 2 - Trang 702-704 vol.2
The U.S. Navy is permanently forward-deployed and depends critically on precise knowledge and predictability of global environmental conditions from under the ocean, throughout the atmosphere and into near-Earth space. To satisfy global mission needs, the Navy depends on spaceborne remote sensing platforms to characterize and monitor each of these environments at wavelengths from the microwave to ...... hiện toàn bộ

The impact of data aggregation in wireless sensor networksProceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 575-578
Sensor networks are distributed event-based systems that differ from traditional communication networks in several ways: sensor networks have severe energy constraints, redundant low-rate data, and many-to-one flows. Data-centric mechanisms that perform in-network aggregation of data are needed in this setting for energy-efficient information flow. In this paper we model data-centric routing and c...... hiện toàn bộ

Learning from data: a tutorial with emphasis on modern pattern recognition methodsIEEE Sensors Journal - Tập 2 Số 3 - Trang 203-217 - 2002
The purposes of this tutorial are twofold. First, it reviews the classical statistical learning scenario by highlighting its fundamental taxonomies and its key aspects. The second aim of the paper is to introduce some modern (ensembles) methods developed inside the machine learning field. The tutorial starts by putting the topic of supervised learning into the broader context of data analysis and ...... hiện toàn bộ

Information-theoretic bounds on target recognition performance based on degraded image dataIEEE Transactions on Pattern Analysis and Machine Intelligence - Tập 24 Số 9 - Trang 1153-1166 - 2002
This paper derives bounds on the performance of statistical object recognition systems, wherein an image of a target is observed by a remote sensor. Detection and recognition problems are modeled as composite hypothesis testing problems involving nuisance parameters. We develop information-theoretic performance bounds on target recognition based on statistical models for sensors and data, and exam...... hiện toàn bộ
