advancements are being used by the armed forces to reduce the risk of their losses and to defeat their enemies. The development of sophisticated technology relies mostly on the use of high- tech weapons or machinery. Robotics is one of the hot spheres of the modern age in which nations concentrate on the state of war and peace for military purposes. They have been in use for demining and rescue operations for some time now but are being propelled by using them for combat and spy missions. This project focuses on creating a LoRa-based spying robot with a wireless IP camera attached to it that can rising the human target. This robot transmits the signal via an IP camera to the base station. One of this project’s major applications can be analyzed using a PC that can be used to control the robot’s movement. The robot sends the signal through the LoRa transceiver at the base station to the LoRa transceiver mounted on the robot. With this function, the, robot can relay videos in real- time along with anti-collision capabilities and the enemies in the war zone cannot recognize them. More importantly, this project focuses on increasing communication using LoRa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lora" title="lora">lora</a>, <a href="https://publications.waset.org/abstracts/search?q=IP%20cam" title=" IP cam"> IP cam</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20detector" title=" metal detector"> metal detector</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20shoot" title=" laser shoot"> laser shoot</a> </p> <a href="https://publications.waset.org/abstracts/165994/warfield-spying-robot-using-lora" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165994.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">111</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Dual Band LoRa/GPS Dipole Antenna with Harmonic Suppression Capability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amar%20Danial%20Abd%20Azis">Amar Danial Abd Azis</a>, <a href="https://publications.waset.org/abstracts/search?q=Shipun%20Anuar%20Hamzah"> Shipun Anuar Hamzah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Noh%20Dalimin"> Mohd Noh Dalimin</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairun%20Nidzam%20Ramli"> Khairun Nidzam Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Sani%20Yahya"> Mohd Sani Yahya</a>, <a href="https://publications.waset.org/abstracts/search?q=Fauziahanim%20Che%20Seman"> Fauziahanim Che Seman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the design, simulation results, and testing of a compact dual-band printed dipole antenna operating at frequencies of 916 MHz and 1.57 GHz for LoRa and GPS applications, respectively. The basic design of this antenna uses a linear dipole that operates at 916 MHz and 2.7 GHz. A small triangular-shaped linear balun has been developed as the matching network. Parasitic elements are employed to tune the second frequency to 1.57 GHz through a parametric study. Meanwhile, a stub is used to suppress the undesired 2.6 GHz frequency. This antenna is capable of operating on dual-frequency bands simultaneously with high efficiency in suppressing the unwanted frequency. The antenna exhibits the following parameters: return loss of -18.5 dB at 916 MHz and -14 dB at 1.57 GHz, VSWR of 1.25 at 868 MHz and 1.5 at 1.57 GHz, and gain of 2 dBi at 916 MHz and 2.75 dBi at 1.57 GHz. The radiation pattern of the antenna shows a directional E-plane and an omnidirectional H-plane at both frequencies. With its compact size and dual-band capability, this antenna demonstrates great potential for use in IoT applications that require both LoRa and GPS communication, particularly in applications where a small yet efficient form factor is essential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual%20band" title="dual band">dual band</a>, <a href="https://publications.waset.org/abstracts/search?q=dipole%20antenna" title=" dipole antenna"> dipole antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20elements" title=" parasitic elements"> parasitic elements</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonic%20suppression" title=" harmonic suppression"> harmonic suppression</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa%20and%20Gps" title=" LoRa and Gps"> LoRa and Gps</a> </p> <a href="https://publications.waset.org/abstracts/194483/dual-band-loragps-dipole-antenna-with-harmonic-suppression-capability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194483.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">6</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Performance Evaluation of a Wireless 433 MHz Link in Underwater-Freshwater Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xavi%20Vilajosana%20Guillen">Xavi Vilajosana Guillen</a>, <a href="https://publications.waset.org/abstracts/search?q=Emilio%20Jos%C3%A9%20P%C3%A9rez%20Salgado"> Emilio José Pérez Salgado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This document presents experimental results obtained in a realistic environment using an underwater LoRa link.

Traditional learning outcome definition techniques such as Bloom’s taxonomy are not written to be utilized by the student. This might be disadvantageous for students in student-centric learning settings where the students are expected to formulate their own learning strategies. To solve the problem, we propose the learning outcome relation and aggregation (LORA) model. To achieve alignment, we developed learning outcome, assessment, and resource authoring tools which help teachers to tag learning outcomes during creation. A pilot study was conducted with an expert panel consisting of experienced professionals in the education domain to evaluate whether the LORA model and tools present an improvement over the traditional methods. The panel unanimously agreed that the model and tools are beneficial and effective. Moreover, it helped them model learning outcomes in a more student centric and descriptive way. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=learning%20design" title="learning design">learning design</a>, <a href="https://publications.waset.org/abstracts/search?q=constructive%20alignment" title=" constructive alignment"> constructive alignment</a>, <a href="https://publications.waset.org/abstracts/search?q=Bloom%E2%80%99s%20taxonomy" title=" Bloom’s taxonomy"> Bloom’s taxonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20outcome%20modelling" title=" learning outcome modelling"> learning outcome modelling</a> </p> <a href="https://publications.waset.org/abstracts/142400/lora-a-learning-outcome-modelling-approach-for-higher-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142400.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> An Analysis of LoRa Networks for Rainforest Monitoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Castilho%20Carvalho">Rafael Castilho Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Edjair%20de%20Souza%20Mota"> Edjair de Souza Mota</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the largest contributor to the biogeochemical functioning of the Earth system, the Amazon Rainforest has the greatest biodiversity on the planet, harboring about 15% of all the world's flora. Recognition and preservation are the focus of research that seeks to mitigate drastic changes, especially anthropic ones, which irreversibly affect this biome. Functional and low-cost monitoring alternatives to reduce these impacts are a priority, such as those using technologies such as Low Power Wide Area Networks (LPWAN). Promising, reliable, secure and with low energy consumption, LPWAN can connect thousands of IoT devices, and in particular, LoRa is considered one of the most successful solutions to facilitate forest monitoring applications. Despite this, the forest environment, in particular the Amazon Rainforest, is a challenge for these technologies, requiring work to identify and validate the use of technology in a real environment. To investigate the feasibility of deploying LPWAN in remote water quality monitoring of rivers in the Amazon Region, a LoRa-based test bed consisting of a Lora transmitter and a LoRa receiver was set up, both parts were implemented with Arduino and the LoRa chip SX1276. The experiment was carried out at the Federal University of Amazonas, which contains one of the largest urban forests in Brazil. There are several springs inside the forest, and the main goal is to collect water quality parameters and transmit the data through the forest in real time to the gateway at the uni. In all, there are nine water quality parameters of interest. Even with a high collection frequency, the amount of information that must be sent to the gateway is small. However, for this application, the battery of the transmitter device is a concern since, in the real application, the device must run without maintenance for long periods of time. With these constraints in mind, parameters such as Spreading Factor (SF) and Coding Rate (CR), different antenna heights, and distances were tuned to better the connectivity quality, measured with RSSI and loss rate. A handheld spectrum analyzer RF Explorer was used to get the RSSI values. Distances exceeding 200 m have soon proven difficult to establish communication due to the dense foliage and high humidity. The optimal combinations of SF-CR values were 8-5 and 9-5, showing the lowest packet loss rates, 5% and 17%, respectively, with a signal strength of approximately -120 dBm, these being the best settings for this study so far. The rains and climate changes imposed limitations on the equipment, and more tests are already being conducted. Subsequently, the range of the LoRa configuration must be extended using a mesh topology, especially because at least three different collection points in the same water body are required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IoT" title="IoT">IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=LPWAN" title=" LPWAN"> LPWAN</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa" title=" LoRa"> LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=coverage" title=" coverage"> coverage</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20rate" title=" loss rate"> loss rate</a>, <a href="https://publications.waset.org/abstracts/search?q=forest" title=" forest"> forest</a> </p> <a href="https://publications.waset.org/abstracts/165277/an-analysis-of-lora-networks-for-rainforest-monitoring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165277.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Development of a Flexible Lora-Based Wireless Sensory System for Long-Time Health Monitoring of Civil Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hui%20Zhang">Hui Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sherif%20Beskhyroun"> Sherif Beskhyroun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a highly flexible LoRa-Based wireless sensing system was used to assess the strain state performance of building structures. The system was developed to address the local damage limitation of structural health monitoring (SHM) systems. The system is part of an intelligent SHM system designed to monitor, collect and transmit strain changes in key structural components. The main purpose of the wireless sensor system is to reduce the development and installation costs, and reduce the power consumption of the system, so as to achieve long-time monitoring. The highly stretchable flexible strain gauge is mounted on the surface of the structure and is waterproof, heat resistant, and low temperature resistant, greatly reducing the installation and maintenance costs of the sensor. The system was also developed with the aim of using LoRa wireless communication technology to achieve both low power consumption and long-distance transmission, therefore solving the problem of large-scale deployment of sensors to cover more areas in large structures. In the long-term monitoring of the building structure, the system shows very high performance, very low actual power consumption, and wireless transmission stability. The results show that the developed system has a high resolution, sensitivity, and high possibility of long-term monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LoRa" title="LoRa">LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=SHM%20system" title=" SHM system"> SHM system</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20measurement" title=" strain measurement"> strain measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20structures" title=" civil structures"> civil structures</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20sensing%20system" title=" flexible sensing system"> flexible sensing system</a> </p> <a href="https://publications.waset.org/abstracts/159969/development-of-a-flexible-lora-based-wireless-sensory-system-for-long-time-health-monitoring-of-civil-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159969.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> WSN System Warns Atta Cephalotes Climbing in Mango Fruit Trees</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Federico%20Hahn%20Schlam">Federico Hahn Schlam</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferm%C3%ADn%20Mart%C3%ADnez%20Sol%C3%ADs"> Fermín Martínez Solís</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leaf-cutting ants (Atta cephalotes) forage from mango tree leaves and flowers to feed their colony. Farmers find it difficult to control ants due to the great quantity of trees grown in commercial orchards. In this article, IoT can support farmers for ant detection in real time, as production losses can be considered of 324 US per tree.A wireless sensor network, WSN, was developed to warn the farmer from ant presence in trees during a night. Mango trees were gathered into groups of 9 trees, where the central tree holds the master microcontroller, and the other eight trees presented slave microcontrollers (nodes). At each node, anemitter diode-photodiode unitdetects ants climbing up. A capacitor is chargedand discharged after being sampled every ten minutes. The system usesBLE (Bluetooth Low Energy) to communicate between the master microcontroller by BLE.When ants were detected the number of the tree was transmitted via LoRa from the masterto the producer smartphone to warn him. In this paper, BLE, LoRa, and energy consumption were studied under variable vegetation in the orchard. During 2018, 19 trees were attacked by ants, and ants fed 26.3% of flowers and 73.7% of leaves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BLE" title="BLE">BLE</a>, <a href="https://publications.waset.org/abstracts/search?q=atta%20cephalotes" title=" atta cephalotes"> atta cephalotes</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa" title=" LoRa"> LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN-smartphone" title=" WSN-smartphone"> WSN-smartphone</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a> </p> <a href="https://publications.waset.org/abstracts/148229/wsn-system-warns-atta-cephalotes-climbing-in-mango-fruit-trees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148229.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Advancing UAV Operations with Hybrid Mobile Network and LoRa Communications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Annika%20J.%20Meyer">Annika J.

One common approach to ensure redundant communication systems when flying beyond visual line of sight is for UAVs to employ multiple mobile data modems by different providers. Although widely adopted, this approach suffers from several drawbacks, such as high costs, added weight and potential increases in signal interference. In light of these challenges, this paper proposes a communication framework intermeshing mobile networks and LoRa (Long Range) technology—a low-power, long-range communication protocol. LoRaWAN (Long Range Wide Area Network) is commonly used in Internet of Things applications, relying on stationary gateways and Internet connectivity. This paper, however, utilizes the underlying LoRa protocol, taking advantage of the protocol’s low power and long-range capabilities while ensuring efficiency and reliability. Conducted in collaboration with the Potsdam Fire Department, the implementation of mobile network technology in combination with the LoRa protocol in small UAVs (take-off weight < 0.4 kg), specifically designed for search and rescue and area monitoring missions, is explored. This research aims to test the viability of LoRa as an additional redundant communication system during UAV flights as well as its intermeshing with the primary, mobile network-based controller. The methodology focuses on direct UAV-to-UAV and UAV-to-ground communications, employing different spreading factors optimized for specific operational scenarios—short-range for UAV-to-UAV interactions and long-range for UAV-to-ground commands. This explored use case also dramatically reduces one of the major drawbacks of LoRa communication systems, as a line of sight between the modules is necessary for reliable data transfer. Something that UAVs are uniquely suited to provide, especially when deployed as a swarm. Additionally, swarm deployment may enable UAVs that have lost contact with their primary network to reestablish their connection through another, better-situated UAV. The experimental setup involves multiple phases of testing, starting with controlled environments to assess basic communication capabilities and gradually advancing to complex scenarios involving multiple UAVs. Such a staged approach allows for meticulous adjustment of parameters and optimization of the communication protocols to ensure reliability and effectiveness. Furthermore, due to the close partnership with the Fire Department, the real-world applicability of the communication system is assured. The expected outcomes of this paper include a detailed analysis of LoRa's performance as a communication tool for UAVs, focusing on aspects such as signal integrity, range, and reliability under different environmental conditions. Additionally, the paper seeks to demonstrate the cost-effectiveness and operational efficiency of using a single type of communication technology that reduces UAV payload and power consumption. By shifting from traditional cellular network communications to a more robust and versatile cellular and LoRa-based system, this research has the potential to significantly enhance UAV capabilities, especially in critical applications where reliability is paramount. The success of this paper could pave the way for broader adoption of LoRa in UAV communications, setting a new standard for UAV operational communication frameworks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LoRa%20communication%20protocol" title="LoRa communication protocol">LoRa communication protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20network%20communication" title=" mobile network communication"> mobile network communication</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV%20communication%20systems" title=" UAV communication systems"> UAV communication systems</a>, <a href="https://publications.waset.org/abstracts/search?q=search%20and%20rescue%20operations" title=" search and rescue operations"> search and rescue operations</a> </p> <a href="https://publications.waset.org/abstracts/186081/advancing-uav-operations-with-hybrid-mobile-network-and-lora-communications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186081.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">43</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Using Multiple Strategies to Improve the Nursing Staff Edwards Lifesciences Hemodynamic Monitoring Correctness of Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hsin-Yi%20Lo">Hsin-Yi Lo</a>, <a href="https://publications.waset.org/abstracts/search?q=Huang-Ju%20Jiun"> Huang-Ju Jiun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Chiao%20Chu"> Yu-Chiao Chu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hemodynamic monitoring is an important in the intensive care unit.

Environmental parameters are critical information to air pollution and weather monitoring. Thus, it is necessary to develop a suitable air pollution and weather monitoring system for urban areas. In this study, a vehicle monitoring system (VMS) based on the IoT technique is developed. Cars are selected as the research tool because it can reach a greater number of streets to collect data. The VMS can monitor different environmental parameters, including ambient temperature and humidity, and air quality parameters, including PM2.5, NO<sub>2</sub>, CO, and O<sub>3</sub>. The VMS can provide other information, including GPS signals and the vibration information through driving a car on the street. Different sensor modules are used to measure the parameters and collect the measured data and transmit them to a cloud server through the LoRa protocol. A user interface is used to show the sensing data storing at the cloud server. To examine the performance of the system, a researcher drove a Nissan x-trail 1998 to the area close to the Da’an District office in Taipei to collect monitoring data. The collected data are instantly shown on the user interface. The four kinds of information are provided by the interface: GPS positions, weather parameters, vehicle information, and air quality information. With the VMS, users can obtain the information regarding air quality and weather conditions when they drive their car to an urban area. Also, government agencies can make decisions on traffic planning based on the information provided by the proposed VMS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LoRa" title="LoRa">LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20system" title=" monitoring system"> monitoring system</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle" title=" vehicle"> vehicle</a> </p> <a href="https://publications.waset.org/abstracts/63748/a-vehicle-monitoring-system-based-on-the-lora-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63748.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">416</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Airon Project: IoT-Based Agriculture System for the Optimization of Irrigation Water Consumption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%81frica%20Vicario">África Vicario</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20J.%20%C3%81lvarez"> Fernando J.

The AIRON Project tries to solve this problem by implementing an IoT-based system to sensor the irrigation plots so that the state of the crops and the amount of water used for irrigation can be known remotely. The IoT system consists of a sensor network that measures the humidity of the soil, the weather conditions (temperature, relative humidity, wind and solar radiation) and the irrigation water flow. The communication between this network and a central gateway is conducted by means of long-range wireless communication that depends on the characteristics of the irrigation plot. The main objective of the AIRON project is to deploy an IoT sensor network in two different plots of the irrigation community of Aranjuez in the Spanish region of Madrid. The first plot is 2 km away from the central gateway, so LoRa has been used as the base communication technology. The problem with this plot is the absence of mains electric power, so devices with energy-saving modes have had to be used to maximize the external batteries' use time. An ESP32 SOC board with a LoRa module is employed in this case to gather data from the sensor network and send them to a gateway consisting of a Raspberry Pi with a LoRa hat. The second plot is located 18 km away from the gateway, a range that hampers the use of LoRa technology. In order to establish reliable communication in this case, the long-term evolution (LTE) standard is used, which makes it possible to reach much greater distances by using the cellular network. As mains electric power is available in this plot, a Raspberry Pi has been used instead of the ESP32 board to collect sensor data. All data received from the two plots are stored on a proprietary server located at the irrigation management company's headquarters. The analysis of these data by means of machine learning algorithms that are currently under development should allow a short-term prediction of the irrigation water demand that would significantly reduce the waste of this increasingly valuable natural resource. The major finding of this work is the real possibility of deploying a remote sensing system for irrigated plots by using Commercial-Off-The-Shelf (COTS) devices, easily scalable and adaptable to design requirements such as the distance to the control center or the availability of mains electrical power at the site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title="internet of things">internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20water%20control" title=" irrigation water control"> irrigation water control</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa" title=" LoRa"> LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=LTE" title=" LTE"> LTE</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20farming" title=" smart farming"> smart farming</a> </p> <a href="https://publications.waset.org/abstracts/165894/airon-project-iot-based-agriculture-system-for-the-optimization-of-irrigation-water-consumption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165894.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Spatial Correlation of Channel State Information in Real Long Range Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdelghany">Ahmed Abdelghany</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernard%20Uguen"> Bernard Uguen</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Moy"> Christophe Moy</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Lemur"> Dominique Lemur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Internet of Things (IoT) is developed to ensure monitoring and connectivity within different applications. Thus, it is critical to study the channel propagation characteristics in Low Power Wide Area Network (LPWAN), especially Long Range Wide Area Network (LoRaWAN). In this paper, an in-depth investigation of the reciprocity between the uplink and downlink Channel State Information (CSI) is done by performing an outdoor measurement campaign in the area of Campus Beaulieu in Rennes. At each different location, the CSI reciprocity is quantified using the Pearson Correlation Coefficient (PCC) which shows a very high linear correlation between the uplink and downlink CSI. This reciprocity feature could be utilized for the physical layer security between the node and the gateway. On the other hand, most of the CSI shapes from different locations are highly uncorrelated from each other. Hence, it can be anticipated that this could achieve significant localization gain by utilizing the frequency hopping in the LoRa systems by getting access to a wider band. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IoT" title="IoT">IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=LPWAN" title=" LPWAN"> LPWAN</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa" title=" LoRa"> LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20signal%20power" title=" effective signal power"> effective signal power</a>, <a href="https://publications.waset.org/abstracts/search?q=onsite%20measurement" title=" onsite measurement"> onsite measurement</a> </p> <a href="https://publications.waset.org/abstracts/137827/spatial-correlation-of-channel-state-information-in-real-long-range-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137827.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Real-Time Mine Safety System with the Internet of Things</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eakir%20Bing%C3%B6l">Şakir Bingöl</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayram%20%C4%B0slamo%C4%9Flu"> Bayram İslamoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebubekir%20Furkan%20Tepeli"> Ebubekir Furkan Tepeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Mehmet%20Karakule"> Fatih Mehmet Karakule</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20K%C3%BC%C3%A7%C3%BCk"> Fatih Küçük</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20Sena%20Arpac%C4%B1k"> Merve Sena Arpacık</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Taha%20Kabar"> Mustafa Taha Kabar</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammet%20Metin%20Molak"> Muhammet Metin Molak</a>, <a href="https://publications.waset.org/abstracts/search?q=Osman%20Emre%20Turan"> Osman Emre Turan</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96mer%20Faruk%20Yesir"> Ömer Faruk Yesir</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C4%B1la%20%C4%B0nan%C4%B1r"> Sıla İnanır</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study introduces an IoT-based real-time safety system for mining, addressing global safety challenges.

In large sized farms, traditional methods based on direct observation or analysis of video recordings become labour-intensive and time-consuming. Thus, automatic monitoring systems using sensors have become increasingly important to continuously and accurately track the health status of dairy cows. Wireless sensor networks (WSNs) and internet-of-things (IoT) can be effectively used in health tracking of dairy cows to facilitate herd management and enhance the cow welfare. Since on-cow measuring devices are energy-constrained, a proper characterization of the off-body wireless channel between the on-cow sensor nodes and the back-end base station is required for a power-optimized deployment of these networks in barns. The aim of this study was to characterize the off-body wireless channel in indoor (barns) environment at 868 MHz using LoRa nodes. LoRa is an emerging wireless technology mainly targeted at WSNs and IoT networks. Both large scale fading (i.e., path loss) and temporal fading were investigated. The obtained path loss values as a function of the transmitter-receiver separation were well fitted by a lognormal path loss model. The path loss showed an additional increase of 4 dB when the wireless node was actually worn by the cow. The temporal fading due to movement of other cows was well described by Rician distributions with a K-factor of 8.5 dB. Based on this characterization, network planning and energy consumption optimization of the on-body wireless nodes could be performed, which enables the deployment of reliable dairy cow monitoring systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=channel" title="channel">channel</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20modelling" title=" channel modelling"> channel modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%20monitoring" title=" cow monitoring"> cow monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20cows" title=" dairy cows"> dairy cows</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20monitoring" title=" health monitoring"> health monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa" title=" LoRa"> LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=off-body%20propagation" title=" off-body propagation"> off-body propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=PLF" title=" PLF"> PLF</a>, <a href="https://publications.waset.org/abstracts/search?q=propagation" title=" propagation"> propagation</a> </p> <a href="https://publications.waset.org/abstracts/72679/off-body-sub-ghz-wireless-channel-characterization-for-dairy-cows-in-barns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> A Long Range Wide Area Network-Based Smart Pest Monitoring System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yun-Chung%20Yu">Yun-Chung Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan-Wen%20Wang"> Yan-Wen Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Sheng%20Liao"> Min-Sheng Liao</a>, <a href="https://publications.waset.org/abstracts/search?q=Joe-Air%20Jiang"> Joe-Air Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuen-Chung%20Lee"> Yuen-Chung Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes to use a Long Range Wide Area Network (LoRaWAN) for a smart pest monitoring system which aims at the oriental fruit fly (Bactrocera dorsalis) to improve the communication efficiency of the system. The oriental fruit fly is one of the main pests in Southeast Asia and the Pacific Rim. Different smart pest monitoring systems based on the Internet of Things (IoT) architecture have been developed to solve problems of employing manual measurement. These systems often use Octopus II, a communication module following the 2.4GHz IEEE 802.15.4 ZigBee specification, as sensor nodes. The Octopus II is commonly used in low-power and short-distance communication. However, the energy consumption increase as the logical topology becomes more complicate to have enough coverage in the large area. By comparison, LoRaWAN follows the Low Power Wide Area Network (LPWAN) specification, which targets the key requirements of the IoT technology, such as secure bi-directional communication, mobility, and localization services. The LoRaWAN network has advantages of long range communication, high stability, and low energy consumption. The 433MHz LoRaWAN model has two superiorities over the 2.4GHz ZigBee model: greater diffraction and less interference. In this paper, The Octopus II module is replaced by a LoRa model to increase the coverage of the monitoring system, improve the communication performance, and prolong the network lifetime. The performance of the LoRa-based system is compared with a ZigBee-based system using three indexes: the packet receiving rate, delay time, and energy consumption, and the experiments are done in different settings (e.g. distances and environmental conditions). In the distance experiment, a pest monitoring system using the two communication specifications is deployed in an area with various obstacles, such as buildings and living creatures, and the performance of employing the two communication specifications is examined. The experiment results show that the packet receiving the rate of the LoRa-based system is 96% , which is much higher than that of the ZigBee system when the distance between any two modules is about 500m. These results indicate the capability of a LoRaWAN-based monitoring system in long range transmission and ensure the stability of the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LoRaWan" title="LoRaWan">LoRaWan</a>, <a href="https://publications.waset.org/abstracts/search?q=oriental%20fruit%20fly" title=" oriental fruit fly"> oriental fruit fly</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=Octopus%20II" title=" Octopus II"> Octopus II</a> </p> <a href="https://publications.waset.org/abstracts/63806/a-long-range-wide-area-network-based-smart-pest-monitoring-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63806.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Experimental Study and Evaluation of Farm Environmental Monitoring System Based on the Internet of Things, Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farid%20Eltom%20A.%20E.">Farid Eltom A.

The aim of the study is to evaluate the farm environmental monitoring system based on (IoT) and to realize the automated management of agriculture and the implementation of precision production. Until now, irrigation monitoring operations in Sudan have been carried out using traditional methods, which is a very costly and unreliable mechanism. However, by utilizing soil moisture sensors, irrigation can be conducted only when needed without fear of plant water stress. The result showed that software application allows farmers to display current and historical data on soil moisture and nutrients in the form of line charts. Design measurements of the soil factors: moisture, electrical, humidity, conductivity, temperature, pH, phosphorus, and potassium; these factors, together with a timestamp, are sent to the data server using the Lora WAN interface. It is considered scientifically agreed upon in the modern era that artificial intelligence works to arrange the necessary procedures to take care of the terrain, predict the quality and quantity of production through deep analysis of the various operations in agricultural fields, and also support monitoring of weather conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20environment" title="smart environment">smart environment</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20systems" title=" monitoring systems"> monitoring systems</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa%20Gateway" title=" LoRa Gateway"> LoRa Gateway</a>, <a href="https://publications.waset.org/abstracts/search?q=center%20pivot" title=" center pivot"> center pivot</a> </p> <a href="https://publications.waset.org/abstracts/182419/experimental-study-and-evaluation-of-farm-environmental-monitoring-system-based-on-the-internet-of-things-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182419.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">48</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> An Approach to Determine the in Transit Vibration to Fresh Produce Using Long Range Radio (LORA) Wireless Transducers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indika%20Fernando">Indika Fernando</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiangang%20Fei"> Jiangang Fei</a>, <a href="https://publications.waset.org/abstracts/search?q=Roger%20Stanely"> Roger Stanely</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Enshaei"> Hossein Enshaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ever increasing demand for quality fresh produce by the consumers, had increased the gravity on the post-harvest supply chains in multi-fold in the recent years. Mechanical injury to fresh produce was a critical factor for produce wastage, especially with the expansion of supply chains, physically extending to thousands of miles. The impact of vibration damages in transit was identified as a specific area of focus which results in wastage of significant portion of the fresh produce, at times ranging from 10% to 40% in some countries. Several studies were concentrated on quantifying the impact of vibration to fresh produce, and it was a challenge to collect vibration impact data continuously due to the limitations in battery life or the memory capacity in the devices. Therefore, the study samples were limited to a stretch of the transit passage or a limited time of the journey. This may or may not give an accurate understanding of the vibration impacts encountered throughout the transit passage, which limits the accuracy of the results. Consequently, an approach which can extend the capacity and ability of determining vibration signals in the transit passage would contribute to accurately analyze the vibration damage along the post-harvest supply chain. A mechanism was developed to address this challenge, which is capable of measuring the in transit vibration continuously through the transit passage subject to a minimum acceleration threshold (0.1g). A system, consisting six tri-axel vibration transducers installed in different locations inside the cargo (produce) pallets in the truck, transmits vibration signals through LORA (Long Range Radio) technology to a central device installed inside the container. The central device processes and records the vibration signals transmitted by the portable transducers, along with the GPS location. This method enables to utilize power consumption for the portable transducers to maximize the capability of measuring the vibration impacts in the transit passage extending to days in the distribution process. The trial tests conducted using the approach reveals that it is a reliable method to measure and quantify the in transit vibrations along the supply chain. The GPS capability enables to identify the locations in the supply chain where the significant vibration impacts were encountered. This method contributes to determining the causes, susceptibility and intensity of vibration impact damages to fresh produce in the post-harvest supply chain. Extensively, the approach could be used to determine the vibration impacts not limiting to fresh produce, but for products in supply chains, which may extend from few hours to several days in transit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post-harvest" title="post-harvest">post-harvest</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20transducers" title=" wireless transducers"> wireless transducers</a>, <a href="https://publications.waset.org/abstracts/search?q=LORA" title=" LORA"> LORA</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20produce" title=" fresh produce"> fresh produce</a> </p> <a href="https://publications.waset.org/abstracts/55839/an-approach-to-determine-the-in-transit-vibration-to-fresh-produce-using-long-range-radio-lora-wireless-transducers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55839.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Surgical School Project: Implementation Educational Plan for Adolescents Awaiting Bariatric Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brooke%20Sweeney">Brooke Sweeney</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20White"> David White</a>, <a href="https://publications.waset.org/abstracts/search?q=Felix%20Amparano"> Felix Amparano</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20A.%20Clark"> Nick A.

Since 2017 our surgery program has used defined protocols and educational curricula pre- and post-surgery. In response to patient outcomes, our educational content was refined to include quizzes to assess patient knowledge and surgical preparedness. We aim to optimize adolescent pre-bariatric surgery preparedness by improving overall aggregate pre-surgical assessment performance from 68% to 80% within 12 months. Methods: A multidisciplinary improvement team was developed within the weight management clinic (WMC) of our tertiary care, free-standing children’s hospital. A manual has been utilized since 2017, with limitations in consistent delivery and patient uptake of information. The curriculum has been improved to include quizzes administered during WMC visits prior to bariatric surgery. The initial outcome measure is the pre-surgical quiz score of adolescents preparing for bariatric surgery. Process measure was the number of questions answered correctly to test the questions. Baseline performance was determined by a patient assessment survey of pre-surgical preparedness at patient visits. Plan-Do-Study-Act cycles (PDSA) included: 1) creation and implementation of a refined curriculum, 2) development of 5 new quizzes based upon learning objectives, and 3) improving provider-lead teaching and quiz administration within clinic workflow. Run charts assessed impact over time. Results: A total of 346 quiz questions were administered to 34 adolescents. The outcome measure improved from a baseline mean of 68% to 86% following PDSA 2 cycles, and it was sustained. Conclusion/Implication: Patient/family comprehension of surgical preparedness improved with standardized education via team member-led teaching and assessment using quizzes during pre-surgical clinic visits. The next steps include launching redesigned teaching materials with modules correlated to quizzes and assessment of comprehension and outcomes post-surgically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bariatric%20surgery" title="bariatric surgery">bariatric surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescent" title=" adolescent"> adolescent</a>, <a href="https://publications.waset.org/abstracts/search?q=clinic" title=" clinic"> clinic</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-bariatric%20training" title=" pre-bariatric training"> pre-bariatric training</a> </p> <a href="https://publications.waset.org/abstracts/170459/surgical-school-project-implementation-educational-plan-for-adolescents-awaiting-bariatric-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170459.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Improving Screening and Treatment of Binge Eating Disorders in Pediatric Weight Management Clinic through a Quality Improvement Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Fernandez">Cristina Fernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felix%20Amparano"> Felix Amparano</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Tumberger"> John Tumberger</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephani%20Stancil"> Stephani Stancil</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Hampl"> Sarah Hampl</a>, <a href="https://publications.waset.org/abstracts/search?q=Brooke%20Sweeney"> Brooke Sweeney</a>, <a href="https://publications.waset.org/abstracts/search?q=Amy%20R.%20Beck"> Amy R.

Clark</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Adolescents with obesity are at higher risk of disordered eating than the general population. Detection of eating disorders (ED) is difficult. Screening questionnaires may aid in early detection of ED. Our team’s prior efforts focused on increasing ED screening rates to ≥90% using a validated 10-question adolescent binge eating disorder screening questionnaire (ADO-BED). This aim was achieved. We then aimed to improve treatment plan initiation of patients ≥12 years of age who screen positive for BED within our WMC from 33% to 70% within 12 months. Methods: Our WMC is within a tertiary-care, free-standing children’s hospital. A3, an improvement framework, was used. A multidisciplinary team (physicians, nurses, registered dietitians, psychologists, and exercise physiologists) was created. The outcome measure was documentation of treatment plan initiation of those who screen positive (goal 70%). The process measure was ADO-BED screening rate of WMC patients (goal ≥90%). Plan-Do-Study-Act (PDSA) cycle 1 included provider education on current literature and treatment plan initiation based upon ADO-BED responses. PDSA 2 involved increasing documentation of treatment plan and retrain process to providers. Pre-defined treatment plans were: 1) repeat screen in 3-6 months, 2) resources provided only, or 3) comprehensive multidisciplinary weight management team evaluation. Run charts monitored impact over time. Results: Within 9 months, 166 patients were seen in WMC. Process measure showed sustained performance above goal (mean 98%). Outcome measure showed special cause improvement from mean of 33% to 100% (n=31). Of treatment plans provided, 45% received Plan 1, 4% Plan 2, and 46% Plan 3. Conclusion: Through a multidisciplinary improvement team approach, we maintained sustained ADO-BED screening performance, and, prior to our 12-month timeline, achieved our project aim. Our efforts may serve as a model for other multidisciplinary WMCs. Next steps may include expanding project scope to other WM programs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obesity" title="obesity">obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title=" pediatrics"> pediatrics</a>, <a href="https://publications.waset.org/abstracts/search?q=clinic" title=" clinic"> clinic</a>, <a href="https://publications.waset.org/abstracts/search?q=eating%20disorder" title=" eating disorder"> eating disorder</a> </p> <a href="https://publications.waset.org/abstracts/170456/improving-screening-and-treatment-of-binge-eating-disorders-in-pediatric-weight-management-clinic-through-a-quality-improvement-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170456.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Chaotic Dynamics of Cost Overruns in Oil and Gas Megaprojects: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20J.%20Olaniran">O.

Whilst the extant literature is filled with studies on incidents and causes of cost overruns, underlying theories to explain their emergence in oil and gas megaprojects are few. Yet, a way to contain the syndrome of cost overruns is to understand the bases of ‘how and why’ they occur. Such knowledge will also help to develop pragmatic techniques for better overall management of oil and gas megaprojects. The aim of this paper is to explain the development of cost overruns in hydrocarbon megaprojects through the perspective of chaos theory. The underlying principles of chaos theory and its implications for cost overruns are examined and practical recommendations proposed.

In this work we tried to prepare a ceramic electrolyte (Li6.5 La2.5 Ba0.5 Nb Zr O12(LLBNZO)) and sintered the pallets of as-prepared material at elevated temperature like 1050, 1100, 1150 and 1200 °C. The objective to carry out this research was to observe the effect of temperature on porosity, density and transport properties of materials. Preliminary results suggest that the material sintered at higher temperature could show enhanced performance in terms of fast ionic transport. This enhancement in performance can be attributed to low porosity of materials which is result of high temperature sintering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20state%20battery" title="solid state battery">solid state battery</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolyte" title=" electrolyte"> electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=garnet%20structures" title=" garnet structures"> garnet structures</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-ion%20battery" title=" Li-ion battery"> Li-ion battery</a> </p> <a href="https://publications.waset.org/abstracts/42973/effect-of-sintering-temperature-on-transport-properties-of-garnet-type-solid-state-electrolytes-for-energy-storage-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42973.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Extremely Large Sinus Pericranii with Involvement of the Torcular and Associated with Crouzon’s Syndrome </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felipe%20H.%20Sanders">Felipe H.

Although the majority of these vascular structures are due to trauma, some are congenital. Case report: Herein, we report a 5-month-old patient with a very large and fluctuating subcutaneous mass over the occiput and the diagnosis of Crouzon’s syndrome. The child presented with a large midline mass that on imaging, connected to the underlying torcular and was diagnosed as a sinus pericranii. At long-term follow up and without operative intervention, the sinus pericranii resolved. This uncommon relationship is reviewed. Conclusion: Premature closure of posterior fossa sutures as part of Crouzon syndrome can present with large sinus pericranii. Such subcutaneous swellings might resolve spontaneously. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congenital" title="congenital">congenital</a>, <a href="https://publications.waset.org/abstracts/search?q=craniosynostosis" title=" craniosynostosis"> craniosynostosis</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric" title=" pediatric"> pediatric</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular%20malformation" title=" vascular malformation"> vascular malformation</a> </p> <a href="https://publications.waset.org/abstracts/77300/extremely-large-sinus-pericranii-with-involvement-of-the-torcular-and-associated-with-crouzons-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77300.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Half-Human: Examining Right-Wing Authoritarianism and Social Dominance Orientation Effects on Dehumanization Tendencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brianna%20Ross">Brianna Ross</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Sollers"> John Sollers</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Edwards"> Christopher Edwards</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the age of heightened social and political discourse, there is a tendency for individuals and media sources to use dehumanization as a tool to influence group thoughts and attitudes. When considering individual interactions, there is a need to determine what characteristics increase or predict dehumanization. The present study investigated dehumanization tendencies related to social dominance orientation (SDO) and right-wing authoritarianism (RWA) while factoring in political affiliation. Two-hundred and seven individuals participated in an anonymous study to reveal that there was a significant relationship between high SDO and high RWA scores. There was also a significant correlation between the dehumanization of Black Lives Matter and SDO. These findings suggest that those who are “double high” (scoring highly on both SDO and RWA are more likely to dehumanize others, particularly social groups they disagree with. Acknowledging that there are significant changes occurring in the sociopolitical atmosphere, it is essential that researchers understand dehumanization tendencies in modern society to better define the concept of othering and its consequences on social interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dehumanization" title="dehumanization">dehumanization</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20dominance%20orientation" title=" social dominance orientation"> social dominance orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=right-wing%20authoritarianism" title=" right-wing authoritarianism"> right-wing authoritarianism</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20affiliation" title=" political affiliation"> political affiliation</a> </p> <a href="https://publications.waset.org/abstracts/129328/half-human-examining-right-wing-authoritarianism-and-social-dominance-orientation-effects-on-dehumanization-tendencies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129328.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Subacute Thyroiditis Triggered by Sinovac and Oxford-AstraZeneca Vaccine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ratchaneewan%20Salao">Ratchaneewan Salao</a>, <a href="https://publications.waset.org/abstracts/search?q=Steven%20W.%20Edwards"> Steven W.

Side effects are very low, but several adverse effects have been reported. Methods: A 40-year-old female patient, with a previous history of thyroid goitre, developed severe neck pain, headache, nausea and fatigue 7-days after receiving second vaccination with Vaxzevria® (Oxford-AstraZeneca). Clinical and laboratory findings, including thyroid function tests and ultrasound of thyroid glands, were performed. Results: Her left thyroid gland was multinodular enlarged, and severely tender on palpation. She had difficulty in swallowing and had tachycardia but no signs of hyperthyroidism. Laboratory results supported a diagnosis of subacute thyroiditis. She was prescribed NSAID (Ibuprofen 400 mg) and dexamethasone for 3-days and her symptoms resolved. Conclusions: Although this is an extremely rare event, physicians may encounter more cases of this condition due to the extensive vaccination program using this combination of vaccines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SARS-CoV-2" title="SARS-CoV-2">SARS-CoV-2</a>, <a href="https://publications.waset.org/abstracts/search?q=adenoviral%20vector%20vaccines" title=" adenoviral vector vaccines"> adenoviral vector vaccines</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccination" title=" vaccination"> vaccination</a>, <a href="https://publications.waset.org/abstracts/search?q=subacute%20thyroiditis" title=" subacute thyroiditis"> subacute thyroiditis</a> </p> <a href="https://publications.waset.org/abstracts/162529/subacute-thyroiditis-triggered-by-sinovac-and-oxford-astrazeneca-vaccine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162529.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Vibratinal Spectroscopic Identification of Beta-Carotene in Usnic Acid and PAHs as a Potential Martian Analogue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20I.%20Alajtal">A.

Terrestrial analogues of Martian sites have been identified and the biogeological modifications incurred as a result of extremophilic activity have been studied. Analytical instrumentation protocols for the unequivocal detection of biomarkers in suitable geological matrices are critical for future unmanned explorations, including the forthcoming ESA ExoMars mission to search for life on Mars scheduled for 2018 and Raman spectroscopy is currently a part of the Pasteur instrumentation suite of this mission. Here, Raman spectroscopy using 785nm excitation was evaluated for determining various concentrations of beta-carotene in admixture with polyaromatic hydrocarbons and usnic acid have been investigated by Raman microspectrometry to determine the lowest levels detectable in simulation of their potential identification remotely in geobiological conditions in Martian scenarios. Information from this study will be important for the development of a miniaturized Raman instrument for targetting Martian sites where the biosignatures of relict or extant life could remain in the geological record. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=raman%20spectroscopy" title="raman spectroscopy">raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=mars-analog" title=" mars-analog"> mars-analog</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-carotene" title=" beta-carotene"> beta-carotene</a>, <a href="https://publications.waset.org/abstracts/search?q=PAHs" title=" PAHs"> PAHs</a> </p> <a href="https://publications.waset.org/abstracts/1391/vibratinal-spectroscopic-identification-of-beta-carotene-in-usnic-acid-and-pahs-as-a-potential-martian-analogue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1391.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">338</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> 19th Century Exam, 21st Century Policing: An Examination of the New York State Civil Service and Police Officer Recruitment Efforts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Edwards">A. Edwards</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The civil service was created to reform the hiring process for public officials, changing the patronage system to a merit-based system. Though exam reforms continued throughout the 20th century, there have been few during the 21st century, particularly in New York state. In the case of police departments, the civil service exam has acted as a hindrance to its ‘21st Century Policing’ goals and new exam reform efforts have left out officers voices and concerns. Through in-depth interviews of current and retired police officers and local and state civil service administrators in Albany County in New York, this study seeks to understand police influence and insight regarding the civil service exam, placing some of the voice and input for civil service reform on police departments, instead of local and state bureaucrats. The study also looks at the relationship between civil service administrators and police departments. Using practice theory, the study seeks to understand the ways in which the civil service exam was defined in the 20th century and how it is out of step with current thinking while examining possible changes to the civil service exam that would lead to a more equitable hiring process and successful police departments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=civil%20service" title="civil service">civil service</a>, <a href="https://publications.waset.org/abstracts/search?q=hiring" title=" hiring"> hiring</a>, <a href="https://publications.waset.org/abstracts/search?q=merit" title=" merit"> merit</a>, <a href="https://publications.waset.org/abstracts/search?q=policing" title=" policing"> policing</a> </p> <a href="https://publications.waset.org/abstracts/85825/19th-century-exam-21st-century-policing-an-examination-of-the-new-york-state-civil-service-and-police-officer-recruitment-efforts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85825.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Orotic Acid-Induced Fatty Liver in Mink: Characterization and Testing of Bioactive Peptides for Prevention and Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Don%20Buddika%20Oshadi%20Malaweera">Don Buddika Oshadi Malaweera</a>, <a href="https://publications.waset.org/abstracts/search?q=Lora%20Harris"> Lora Harris</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruce%20Rathgeber"> Bruce Rathgeber</a>, <a href="https://publications.waset.org/abstracts/search?q=Chibuike%20C.%20Udenigwe"> Chibuike C.

In North America, nursing sickness affects about 45% of mink farms and in Canada, approximately 50,000 mink females is affected annually. Orotic acid (OA) plays a critical role in lipid metabolism and can increase hepatic lipids by enhancing Sterol regulatory element binding protein-1c expression and decreasing Carnitine palmitoyl transferase I activity. This study was conducted to identify particular pathways and regulatory control points involved in fatty liver development, and evaluate the effectiveness of arginine and bioactive peptides for prevention and treatment of fatty liver disease in mink. A total of 45 mink were used in 9 treatments. The experimental diets consisted of 1% OA, 2% L-arginine and 5% of whey protein hydrolysates. At the end of 10 days of experimental period, the mink were anaesthetized, sampled for blood and euthanized, samples were obtained for histological, biochemical and molecular assays. The blood samples will be analyzed for clinical chemistry and triacylglycerol. The liver samples will be analyzed for total lipid content and analyzed for 6 genes of interest involved in adipogenic transformation, ER stress, and liver inflammation. <p
