Algorithm for Automated Mapping of Land Surface Temperature Using LANDSAT 8 Satellite Data
Journal of Sensors - Tập 2016 - Trang 1-8 - 2016
Land surface temperature is an important factor in many areas, such as global
climate change, hydrological, geo-/biophysical, and urban land use/land cover.
As the latest launched satellite from the LANDSAT family, LANDSAT 8 has opened
new possibilities for understanding the events on the Earth with remote sensing.
This study presents an algorithm for the automatic mapping of land surface
temperat...
Deep Convolutional Neural Networks for Hyperspectral Image Classification
Journal of Sensors - Tập 2015 - Trang 1-12 - 2015
Recently, convolutional neural networks have demonstrated excellent performance
on various visual tasks, including the classification of common two-dimensional
images. In this paper, deep convolutional neural networks are employed to
classify hyperspectral images directly in spectral domain. More specifically,
the architecture of the proposed classifier contains five layers with weights
which are ...
Black Phosphorous and Cytop Nanofilm‐Based Long‐Range SPR Sensor with Enhanced Quality Factor
Journal of Sensors - Tập 2023 Số 1 - 2023
This numerical work proposes two novel designs of long‐range surface plasmon
resonance sensors (LRSPR) using two different coupling prisms. The performance
analysis of the proposed sensor has been investigated using the performance
parameters like quality factor (Q), detection accuracy (DA), sensitivity (S),
and full‐width half maximum (FWHM). The transfer matrix method (TMM) has been
employed to ...
Enhancing Interpretability of Data-Driven Fault Detection and Diagnosis Methodology with Maintainability Rules in Smart Building Management
Journal of Sensors - Tập 2022 - Trang 1-48 - 2022
Data-driven fault detection and diagnosis (FDD) methods, referring to the newer
generation of artificial intelligence (AI) empowered classification methods,
such as data science analysis, big data, Internet of things (IoT), industry 4.0,
etc., become increasingly important for facility management in the smart
building design and smart city construction. While data-driven FDD methods
nowadays outpe...
Application of Distributed Optical Fiber Sensing Technology in Surrounding Rock Deformation Control of TBM-Excavated Coal Mine Roadway
Journal of Sensors - Tập 2018 - Trang 1-10 - 2018
After roadway excavation, the deformation and failure of roadway surrounding
rocks typically results in roadway damage or collapse. Conventional monitoring
techniques, such as extensometers, stress meters, and convergence stations, are
only capable to detect the stress or strain data with the shallow layers of
surrounding rocks, and they require arduous manual works. Moreover, in the
abovementione...
A Survey of Routing Issues and Associated Protocols in Underwater Wireless Sensor Networks
Journal of Sensors - Tập 2017 - Trang 1-17 - 2017
Underwater wireless sensor networks are a newly emerging wireless technology in
which small size sensors with limited energy and limited memory and bandwidth
are deployed in deep sea water and various monitoring operations like tactical
surveillance, environmental monitoring, and data collection are performed
through these tiny sensors. Underwater wireless sensor networks are used for the
explorat...
Experimental Verification for Cable Force Estimation Using Handheld Shooting of Smartphones
Journal of Sensors - Tập 2017 - Trang 1-13 - 2017
Currently, due to the rapid development and popularization of smartphones, the
usage of ubiquitous smartphones has attracted growing interest in the field of
structural health monitoring (SHM). The portable and rapid cable force
measurement for cable-supported structures, such as a cable-stayed bridge and a
suspension bridge, has an important and practical significance in the evaluation
of initial...
Cross-Sectional Loss Quantification for Main Cable NDE Based on the B-H Loop Measurement Using a Total Flux Sensor
Journal of Sensors - Tập 2019 - Trang 1-10 - 2019
In the real world, the main cables of suspension bridges are commonly inspected
by conducting a periodic visual inspection of the exterior cover of the cable.
Although there is a need to conduct a nondestructive evaluation (NDE) of the
damage of the main cable, a suitable NDE technique has not yet been developed
due to the large diameter and low accessibility of the cable. This study
investigates ...
Impact of Topography and Tidal Height on ALOS PALSAR Polarimetric Measurements to Estimate Aboveground Biomass of Mangrove Forest in Indonesia
Journal of Sensors - Tập 2015 - Trang 1-13 - 2015
This study is focused on investigating the impact of topography and tidal height
on ALOS PALSAR polarimetric measurements on HH and HV for estimating aboveground
biomass (AGB) of mangrove forest in Indonesia. We used multitemporal ALOS PALSAR
polarimetric measurement that covered mangrove zone in Banyuasin, Cilacap, and
Teluk Bintuni and also collected tidal height data within the same acquisition...
Square Diaphragm CMUT Capacitance Calculation Using a New Deflection Shape Function
Journal of Sensors - Tập 2011 - Trang 1-12 - 2011
A new highly accurate closed-form capacitance calculation model has been
developed to calculate the capacitance of capacitive micromachined ultrasonic
transducers (CMUTs) built with square diaphragms. The model has been developed
by using a two-dimensional polynomial function that more accurately predicts the
deflection curve of a square diaphragm deformed under the influence of a uniform
external...
