Algorithm for Automated Mapping of Land Surface Temperature Using LANDSAT 8 Satellite Data
Journal of Sensors - Tập 2016 - Trang 1-8 - 2016
Uğur Avdan, Gordana JOVANOVSKA
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 ...... hiện toàn bộ
Deep Convolutional Neural Networks for Hyperspectral Image Classification
Journal of Sensors - Tập 2015 - Trang 1-12 - 2015
Wei Hu, Yangyu Huang, Li Wei, Fan Zhang, Heng-Chao Li
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 wh...... hiện toàn bộ
Black Phosphorous and Cytop Nanofilm‐Based Long‐Range SPR Sensor with Enhanced Quality Factor

Bhishma Karki, Arun Uniyal, G. Srivastava, Amrindra Pal
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 ...... hiện toàn bộ
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
Michael Yit Lin Chew, Ke Yan
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 nowada...... hiện toàn bộ
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
Bin Tang, Hua Cheng
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 above...... hiện toàn bộ
A Survey of Routing Issues and Associated Protocols in Underwater Wireless Sensor Networks
Journal of Sensors - Tập 2017 - Trang 1-17 - 2017
Muhammad Khalid, Zahid Ullah, Naveed Ahmad, Muhammad Ayaz, Bilal Jan, Yue Cao, Awais Adnan
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 ...... hiện toàn bộ
Experimental Verification for Cable Force Estimation Using Handheld Shooting of Smartphones
Journal of Sensors - Tập 2017 - Trang 1-13 - 2017
Xuefeng Zhao, Kwang Ri, Niannian Wang
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...... hiện toàn bộ
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
Ju‐Won Kim, Junkyeong Kim, Seunghee Park
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 inves...... hiện toàn bộ
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
Soni Darmawan, Wataru Takeuchi, Yenni Vetrita, Ketut Wikantika, Dwi Kesuma Sari
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 acq...... hiện toàn bộ
Square Diaphragm CMUT Capacitance Calculation Using a New Deflection Shape Function
Journal of Sensors - Tập 2011 - Trang 1-12 - 2011
Md. Mosaddequr Rahman, Sazzadur Chowdhury
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 ...... hiện toàn bộ
