  • A new voltage sensitivity-based distributed feedback online optimization for voltage control in active distribution networks

    Kinga, S; Megahed, TF; Kanaya, H; Mansour, DEA

    Rising sustainability, environmental, and decarbonization considerations have prompted a recent increase in the integration of inverter-based distributed energy resources (DER), such as photovoltaics (PV), into the power grid. This trend raises concerns about potential voltage violations within distribution systems, emphasizing the growing relevance of effective voltage regulation. Utilizing smart inverters for active and reactive power control proves highly efficient in addressing voltage rise issues within active distribution networks (ADN). This work proposes a distributed feedback online optimization (FOO) strategy for voltage regulation in ADNs. The FOO strategy utilizes online recursive least squares (RLS) sensitivity-based feedback, relying on local measurements to iteratively compute optimal reactive power set points for DERs, ensuring bus voltage regulation to within acceptable limits. The distributed control algorithm employs a primal-dual update approach, enabling coordinated information exchange between neighboring controllers. This online feedback-based control offers a promising solution for real-time coordinated voltage control in distribution grids, particularly with the increasing integration of inverter-based DERs at the grid's edge. The approach demonstrates robustness under varying conditions, communication dynamics, and topology changes, validated using real distribution feeders with actual solar PV production and consumption data. Advancements in sensing, communication systems, and smart grid tools further enhance the feasibility and scalability of this strategy for evolving power systems.

    A digitizer is considered one of the fundamental components of an earthquake monitoring system. In this paper, we design and implement a high accuracy seismic digitizer. The implemented digitizer consists of several blocks, i.e., the analog-to-digital converter (ADC), GPS receiver, and microprocessor. Three finite impulse response (FIR) filters are used to decimate the sampling rate of the input seismic data according to user needs. A graphical user interface (GUI) has been designed for enabling the user to monitor the seismic waveform in real time, and process and adjust the parameters of the acquisition unit. The system casing is designed to resist harsh conditions of the environment. The prototype can represent the three component sensors data in the standard MiniSEED format. The digitizer stream seismic data from the remote station to the main center is based on TCP/IP connection. This protocol ensures data transmission without any losses as long as the data still exist in the ring buffer. The prototype was calibrated by real field testing. The prototype digitizer is integrated with the Egyptian National Seismic Network (ENSN), where a commercial instrument is already installed. Case studies shows that, for the same event, the prototype station improves the solution of the ENSN by giving accurate timing and seismic event parameters. Field test results shows that the event arrival time and the amplitude are approximately the same between the prototype digitizer and the calibrated digitizer. Furthermore, the frequency contents are similar between the two digitizers. Therefore, the prototype digitizer captures the main seismic parameters accurately, irrespective of noise existence.

    A metal-loaded double-layer unidirectional radiation slot antenna with flat gain is proposed for millimeter-wave (mm-wave) operations. Our presented antenna is constituted of a slot antenna with metal vias, an inner floating metal, a metal line, and ground patch. With the help of inner metal excited by the coupling of the slot antenna, an additional resonance point around 26 GHz could be obtained and the antenna gain is enhanced. To verify the design, the antenna has been fabricated with the prepreg technology. The whole fabricated size is only 0.62 × 0.62λ0² with a thickness of 0.057λ0 (λ0 is the free-space wavelength at 26 GHz). The measured impedance bandwidth is from 25.1 to 26.55 GHz. Moreover, the proposed antenna obtains a wide flat gain (5.78 ± 0.48 dBi) within the bandwidth and stable one-sided radiation patterns. The above characteristics show that the proposed antenna is a competitive choice for mm-wave systems.

    Multifocal (MF) and multicentric (MC) breast cancers are more likely to be aggressive than unifocal (UF) breast tumors, and they are linked to high recurrence probability, lymph node metastases, and low survival rates. Metastasis is the process through which cancer cells spread to different body areas. Although the longevity of patients with metastatic breast cancer is high, it is restricted by the growth of brain metastases. Medical imaging techniques have inherent limits. Hence, a precise and sensitive substitution is required. Because microwave imaging is portable, non-ionizing, and affordable, it has become a viable method for the detection of breast cancer. As far as we know, this is the first research aiming at discriminating MF and MC breast cancers from UF ones. This proposal presents a 2×2 planar metasurface-based array antenna in the Industrial Scientific Medical frequency band at 2.4 GHz. The proposed array configuration significantly enhanced the gain to 4 dBi rather than a single element at 50 Ω. The geometric arrangement of the four antenna elements is optimized to discriminate the critical stage of breast cancers (UF, MF, or MC). As the proposed structure does not surround the breast, it contributes to a higher degree of comfort than the conventional antenna configurations. The magnitude and phase of S-parameters of the backscattered signals are analyzed in this research.

    THz technology has the potential to revolutionize various fields, including high-speed wireless communication, medical imaging, and spectroscopy. One challenge facing THz technology, however, is the limited output power (on the order of microwatts) of photonic THz sources (e.g., uni-traveling-carrier photodiode). Researchers are therefore exploring THz beam steering techniques to maximize their power effectiveness. To this end, we propose a photonic THz beam steering method that utilizes fiber chromatic dispersion, eliminating the need for energy-consuming active electronics. This paper explains its basic operating principle, fabrication and performance analysis of the associated THz array antenna, and demonstrates the feasibility of achieving a 300 GHz beam steering within 10∘ by means of dispersion-varied polarization-maintaining fibers. In conclusion, the present scheme can greatly enhance the power efficiency of photonic THz sources, and enable the potential advantages of seamless integration with fiber-optic networks, including reduced complexity, simplified operation, low power consumption, and cost-effectiveness.

    Existing distribution networks were not designed with large-scale electric vehicle (EV) charging infrastructure in mind. Integrating EV charging stations with the distribution grid might lead to power quality (PQ) issues at the point of common coupling (PCC). This work proposes a two-mode, unit template-based synchronous reference frame hysteresis current-controlled (SRF-HCC) three-phase Level 2 EV charger. Mode one focuses on charging the EV battery from the grid (G2V) and utilizes current and voltage control techniques to enhance battery life and performance. Whereas mode two enables the EV's stored energy to be discharged to the grid (V2G) by the EV user, allowing the sale of power to support the transient effect of the grid voltage and frequency and enhancing the grid's PQ. The HCC generates switching pulses for both the AC-DC and buck-boost converters. The SRF-based unit template-based control (SRF-UTC) method ensures system stability, voltage, and frequency regulation for power exchange with the grid by combining its efficiency with that of the HCC. The EV charger proposal comprises three primary components: a 3-phase bidirectional AC-DC converter, a bidirectional buck-boost converter, and a filter circuit. The proposed system was modeled using MATLAB/Simulink and evaluated in two case studies to assess its performance.

    A planar array antenna consisting of a patch antenna fed by a coplanar waveguide (CPW) and a patch antenna excited through near-field coupling is presented. The utilization of a mixed-mode feed line, which incorporates both direct and indirect feed lines, enables radiating elements to resonate at two distinct frequencies. The feed network delivers an electric current to one patch antenna through a metalized via, whereas a surface equivalent magnetic current is induced in the other patch antenna through near-field coupling. Resonance occurs at 26 GHz after balanced series stubs are added to the feed line. To achieve a flat gain response, a notched slot is positioned between the locations of the electric and magnetic current sources. The measurement results of the antenna show a flat gain response covering an impedance bandwidth of 16.45% (25.1–29.6 GHz), which fulfills the 26 GHz and 28 GHz bands of fifth-generation (5G) mobile communication systems.

    Harvesting energy from multiple sources, antenna gain, rectifier power conversion efficiency, and rectenna size are essential properties to consider while designing an antenna for ambient energy harvesting. This paper represents two high-gain, dualband antennas using a metamaterial Artificial Magnetic Conductor array. Both antennas are designed to harvest energy from GSM-1800, and the 2.45 GHz Industrial, Scientific, and Medical (ISM) frequency bands. The first antenna achieves a gain of 6.85 dB and 6.57 dB at 1.8 GHz and 2.45 GHz, respectively. The second configuration shows a gain of 7.11 dB at 1.8 GHz and 6.79 dB at 2.45 GHz. The antennas are circularly polarized at 2.45 GHZ. A dualband rectifier is designed based on a novel matching procedure to complete the energy harvesting system. The measured peak conversion efficiency is 72 % at 1.8 GHz and 65 % at 2.45 GHz with an area of 33 ×55 mm2.

    In Okinawa Prefecture, the custom of eating goat meat is rooted in traditional food culture. However, the self-sufficiency rate for goat meat in Okinawa Prefecture is only about 40%. Even outside the prefecture, most of the domestic consumption is imported meat, so there is a shortage of supply compared to demand, and it is necessary to expand the scale of production. There is a need to establish techniques for raising multiple goats for meat purposes. In this paper, we realize an ear tag type small size low power consumption battery-less senor system (size=30 × 50 × 10 mm) by suppling electrical power from a solar cell on the sensor system. Using the sensor, we succeeded in measuring the real time body surface temperature of goats and found that the surface temperature changes during the estrous period.

    Landslides are one of the most destructive natural hazards that lead to the loss of lives and infrastructures. Understanding the landslide mechanism is one of the important parts of mitigating landslide hazards. The occurrence of landslides can be significantly influenced by the presence of vertical cracks. These cracks act as potential weak points in the slope, making it more susceptible to failure. In this paper, slope model experiments were carried out in the laboratory using K–7 sand incorporating rainfall intensity of 70 mm/h via a sprinkler system. The slope model was simulated with a slope angle of 40°. The main objective of the study was to evaluate the mechanism of slope deformation patterns in two different types of slopes, with vertical cracks and without vertical cracks. The soil moisture content and pore water pressure affect the instability of slope models. The results showed that the distribution of landslide activity was retrogressive and more vulnerable on a slope having vertical cracks compared to a slope without vertical cracks.

    Power electronic converters play a crucial role in integrating distributed generation, renewable energy sources, microgrids, and HVDC transmission networks into the grid. The control technique used in the voltage source inverters (VSI) is essential for handling load variations, system nonlinearity, stability, and fast transient response. This study focuses on improving the robustness and control performance of VSIs by integrating a Kalman filter adaptive observer into a finite control set model predictive control (FCS-MPC), resulting in an improved FCS-MPC strategy (IMPC). The classical FCS-MPC can be affected by inaccuracies due to measurement noise and uncertainties in system models, leading to less accurate predictions and suboptimal control actions. By employing the Kalman filter adaptive observer, real-time estimates of unmeasured variables are provided, compensating for uncertainties, and enhancing control performance. To further enhance flexibility and adaptivity, an artificial neural network (ANN)-based controller is designed. The ANN controller is trained offline using IMPC as baseline thus eliminating the need for online predictions and optimization. The ANN controller directly generates inverter switching configuration states, resulting in high-quality sinusoidal output voltage with low distortions. Comparative analysis is conducted for the classical FCS-MPC, IMPC, support vector machine (SVM), convolutional neural network (CNN), and ANN-based controllers under diverse operating conditions and system parameters. Although it has reduced interpretability, the ANN controller exhibits superior harmonic reduction, outperforming both MPC-based controllers and SVM. Evaluation against CNN-based controls also validates the ANN’s robustness and effectiveness in handling uncertainties, emphasizing its adaptability, efficiency, and practical applicability in power electronic applications.

    In Japan, where ICT is being actively promoted, this research focuses on improving wireless communications in underground structures, especially manholes. The main issue is to achieve stable wireless communication from inside manholes while meeting the basic requirements of manhole covers. Based on previous research, a slit shape that can be implemented in an actual cast iron manhole cover was studied based on the self-complementary pair theory, and the structural characteristics were optimized through analysis. Experimental results showed that the slit structure significantly improved radio transmission, and achieved a 30 dBm improvement in communication strength over conventional products in a wide bandwidth (840 MHz to 920 MHz).

    Water utilities in Japan face a number of challenges, including declining water demand due to a shrinking population, shrinking workforce, and aging water supply facilities. Widespread use of smart water meters is crucial for solving these problems. The widespread use of smart water meters is expected to bring many benefits such as reduced labor by automating meter reading, early identification of leaks, and visualization of pipeline data to strengthen the infrastructure of water services, business continuity, and customer service, as detailed data can be obtained using wireless communication. Demonstration tests are actively conducted in Japan; however, many problems have been reported with cast iron meter boxes blocking radio waves. To address the issue, a low-cost slit structure for cast iron meter boxes is investigated in this study. The results confirm that the L-shaped tapered slit array structure with a cavity, which can be fabricated in a cast iron integral structure, satisfies the design loads required for road installation. The proposed slit structure achieved gain characteristics from −3.32 to more than 9.54 dBi in the 800 to 920 MHz band. The gain characteristics of conventional cast iron meter boxes range from −15 to −20 dBi, and the gain has been significantly improved. Antennas with a gain of −2.0 to +1.5 dB (0.8 to 2.5 GHz) were used for the transmitter antenna, which was found to have a higher gain than the transmit antenna in the 800 to 880 MHz frequency band. In the 1.5 to 2.0 GHz band, a high peak gain of 4.25 dBi was achieved at 1660 MHz, with no null and the lowest gain confirmed that this is an improvement of more than 10 dBi over conventional products.

    Wireless sensor networks (WSNs) have become indispensable for environmental monitoring, especially in infrastructures like waste landfills. This research probed the feasibility of underground WSNs employing low-frequency electromagnetic waves (LFEMW) for transmitting data from sensors embedded within landfill waste layers to surface-based receivers. A conceptual WSN system was designed wherein data from these underground sensors was relayed via LFEMW to a surface receiver. This receiver subsequently forwarded the data to a cloud server. We investigated various factors that might influence LFEMW communication performance, including equipment installation conditions and the specific characteristics of landfill waste. Experiments conducted with incineration ash showcased the potential of LFEMW for underground communication. Furthermore, the research delved into how waste attributes like density, moisture, and metal content can impact communication, thereby reinforcing the practicality of using LFEMWs in landfill contexts. Conclusively, the study affirmed successful wireless communication within a simulated waste landfill over a span of 1 year, highlighting the promise of LFEMWs for consistent, real-time monitoring in landfill scenarios.

    Thermomechanical stress generation on a silicon chip in an embedded-die package (EDP) was investigated. Change in thermomechanical stress on the chip with temperature was evaluated using piezo-resistance gauges fabricated on the chip. To investigate the impact of a redistribution layer (RDL) on stress generation, an EDP where filling materials facing the top and bottom sides and the periphery of the embedded die were entirely removed was fabricated. The removal of filling materials was carried out by using the CO2 laser ablation technology. RDL having diagonal paths from the substrate to the chip was designed and fabricated in addition to the conventional orthogonal RDL. RDLs were made of copper. Temperature tests were carried out in the range from 260°C to 100°C. The experimental results indicate that, while the origin of thermomechanical stress is a mismatch in coefficients of thermal expansion (CTE) between the chip and the organic substrate, RDL plays a significant role in generating the thermomechanical stress on the chip. The results also show that the diagonal RDL design effectively reduces thermomechanical stress from the orthogonal RDL design owing to its spring characteristic.

    Under heavy rainfall, landslide early warning system (LEWS) is considered to be an effective method for providing timely warnings, but previous LEWS presents deficiencies such as high cost, high power consumption, and difficulties in secondary development. To address the shortcomings, the current study developed a low-cost and sustainable LEWS that integrates the Internet of Things (IoT) and an off-the-grid solar energy-powered integrated platform for data acquisition, data transmission, and data analysis. Obtained data such as soil moisture content, pore water pressure, deflection angle, and real-time factor of safety (Fs) are used as auxiliary warning indicators or cross-warning indicators. The LEWS considers three states before a landslide: monitoring state, alert state, and triggering state. Slope model tests and outdoor embankment slope tests were conducted to check the feasibility of the proposed LEWS. Results show that (1) compared with previous LEWS, the development cost and power consumption are greatly reduced, and the newly IoT-based LEWS provides an open architecture to meet different application scenarios and requirements and (2) a series of slope model tests based on LEWS successfully allows monitoring authorities to identify risk level, send warning signals, and predict potential movement so as to make enough time for risk management. The low-cost and standalone energy harvesting feature of the LEWS allows it to be applicable across the world.

    <p>In recent years, smoke and fire accidents have occurred frequently due to crushing of lithium-ion batteries (hereinafter referred to as "LIB") mixed with other waste at the time of waste collection and treatment. In this study, with the aim of constructing an LIB detection system using RFID tags, an automatic recognition technology, we conducted experiments to confirm the basic performance of the tags and to read the tags at multiple measurement sites, using RFID tags currently under development. The results showed that the tags could be detected even when attached to products containing metal objects that weaken radio waves due to their unidirectional directivity. Even in the daily life environment where other radio waves such as Wi-Fi are also flying, the reception performance was confirmed to be equivalent to that of an anechoic chamber if the reception distance is 1 m or less in the laboratory and 2.5 m or less outdoors. Further experiments and studies of detection methods will be conducted for practical use.</p>

    Low gain and directivity are the major drawbacks of conventional microstrip patch antennas (MSA). Microstrip patch antennas come in various shapes, including circular, triangular, and rectangular, and are utilized in numerous fields, including biomedical engineering, the military, and radar. This paper presents a simulated MSA designed for X-band applications (8-10 GHz). The proposal describes a microstrip patch antenna with a metasurface cover fed by a coaxial feed. It improves the performance of conventional microstrip antenna using simulation-based optimization for the best feed position and employing metasurface to enhance gain and directivity. A 4×4 square patches metasurface array is utilized to control the surface wave. The proposed antenna is simulated by analyzing the results of various MSA shapes using Computer Simulation Technology (CST). Here, we compare and examine parameters like reflection coefficient, gain, voltage standing wave ratio (VSWR), and directivity. Circular MSA matching was approximately three times better due to the precise selection of the coaxial feed position compared to the conventional configuration. In addition, the metasurface cover helped the rectangular MSA radiate 80 MHz closer to the desired resonance frequency.

A boost circuit was developed to obtain DC voltage from weak electromagnetic waves. Finally, an EH system composed of a temperature and humidity sensor and a BLE module was constructed to achieve sustained operation of the sensor and BLE without batteries. The total size of the circuit is 35 x 62 mm. We tested an RF (radio wireless) energy harvesting (EH) circuit using the 470-710 MHz band, which is the radio wave for digital terrestrial broadcasting. Field test suggests that the proposed energy harvesting circuit can operate continuously within a radius of 9.6 km from the TV tower.

    The development of the underground structure cover is a method of constructing a sewer water level detection system for flood prevention. The challenge in this design is that the metal cover needs to shield as little as possible of the signal emitted from the antenna in the underground structure. In this paper, we improved the penetration of the underground structure cover by opening self-complementary slit in the cover. A water level sensor is installed in the underground structure and connected to an antenna underneath the cover. The underground structure has been modeled, simulated and measured to obtain the antenna characteristic parameters. Through the slit in the cover, the antenna successfully transmits water level data to the outside. The underground structure cover is shown to perform as expected as verified by outdoor measurements.

    In this paper, we designed a terahertz-band on-chip slot array antenna for imaging devices. Terahertz (THz) waves are suitable for imaging devices for nondestructive, non-contact inspection due to their material permeability, like radio waves, spatial resolution, and many materials with absorption spectra in the terahertz frequency band. However, currently developed imaging devices using rectifier detectors have low detection sensitivity due to the low input voltage to the detector in the terahertz band. Therefore, in this study, a high-gain unidirectional (one-sided directional) slot array antenna for terahertz imaging is designed and fabricated using a minimal fab. The maximum gain was 4.32 dBi at 1.02 THz. 7.31 dBi at 1.02 THz for the array antenna improved the gain by about 3 dB by arraying.

    A quasi-Yagi antenna with parasitic cells and its array are proposed for 5G mm-wave bands. For the antenna unit, through introducing the parasitic cells, the gain could be enhanced maximum of 1.3 dB without increasing the antenna length and a wide bandwidth served for the 5G N258 band. Besides, substrate integrated waveguide (SIW) with short-circuit metal vias is employed as the feed structure and reflector, which can easily tune the impedance matching. For the antenna array, by designing a SIW power divider, the antenna element can be convenient to integrate as a 1 × 4 end-fire array. The antenna unit and its array have been fabricated and measured. The measured results show that the high peak gain of the element and array is 9.06 and 14.38 dB within the operation bands (24.25–27.5 GHz), respectively. It is suitable for miniaturized end-fire devices with 5G N258 mm-wave operation systems.

    This paper presents the performance optimization of a slot antenna using Bayesian Optimization (BO). BO is an optimization technique that can obtain accurate results in a short time with a small amount of data. Two slot antennas with a simple structure for 5GHz-band are designed. The one is the reference slot antenna, which is designed by EM simulation without BO, and the other is the optimized slot antenna which is optimized using BO from the reference slot antenna. One design parameter is optimized to ensure that the optimal solution is obtained. Both the reference slot antenna and the optimized slot antenna are fabricated and tested. EM simulated and measured results have good agreement. As a consequence, the optimized slot antenna provided better antenna characteristics such as reflection coefficient than those of the reference slot antenna. Compared with another optimization technique which is the parametric analysis of the EM simulator, BO achieved reducing the number of EM simulations drastically to find the optimal value.

    For the purpose of developing chemicals-free soil disinfection technology, microwave heating of a watery rod buried in soil has been investigated by using multiphysics simulation, COMSOL. The soil investigated was loamy soil having 13.77% moisture. A 2.45 GHz microwave was radiated using the standard horn antenna. Temperature of the water rod is found to become higher than the surrounding soil. There is a rod radius showing the highest heating rate. The presence of the highest-rate radius suggests that the microwave technique has the potential to develop a pest control method which can keep beneficial microorganisms alive. To improve spatial uniformity and increase heating depth, the pair-plate guide structure and the use of synthesized waves from double horn antenna are investigated.

    An experimental investigation of a thermomechanical stress on a silicon chip in the embedded die substrate was carried out to find out key causes of stress generation. Test packaging structures having air gaps at both sides of the chip and an air gap at either side of the chip were fabricated and tested in addition to the standard fully backfilled structure. The embedded test chip was implemented with silicon piezoresistance gauges to measure the residual stress after packaging and thermomechanical stress. Three resin materials with different coefficients of thermal expansion (CTE) and Young’s modulus were used to evaluate the material dependence of chip stress. The thermomechanical stress on a chip was measured at a temperature between 220̊C and 100̊C. The experimental results indicated that the thermomechanical stress is dominated by the CTE mismatch between the chip and the substrate core frame and constructional materials above or below the chip have less impact on the chip stress. The use of low CTE and low modulus material at the periphery of the chip helps to reduce the stress propagation to the silicon chip from the core frame. In addition, it is found that the use of low modulus material around the chip is effective to keep the stress low over the temperature range tested.

    In this paper, a compact, high-efficiency integrated rectenna is presented to operate in the 2.45 GHz band. A comparison between two rectifier topologies is performed to verify the benefits of removing the matching network from the rectifier. A rectifier high conversion efficiency of 74.1% is achieved. To complete the rectenna system, a novel omnidirectional antenna with high gain (3.72dB) and compact size (25mm*29 mm) is designed and fabricated. The same antenna is used with a reflector for raising the gain to nearly 8.3 dB. The simulation and measurement results of the antenna are in good agreement.

    In recent years, there has been an increase in environmental awareness and the development of IoT. One technology that has been attracting attention is energy harvesting (EH). EH is a technology that harvests unused energy in our surroundings and converts it into electric energy. Although it cannot generate electricity on a large scale, it is being considered for use in devices that can be driven by low power, such as sensors and communication modules like Bluetooth Low Energy (BLE). The high-frequency radio wireless energy focused on in this research is emitted into airspace by many wireless devices and propagates everywhere, but this energy is very weak. In this study, we focused on the electromagnetic waves emitted from UHF-band radio frequency identification (RFID) systems and developed a rectifier circuit that performs RF-DC conversion and boosts the output DC voltage. We also experimented with the proposed circuit to supply power to the sensors and BLE data transmission module.

    The occurrence of rainfall-induced landslides is observed worldwide. National and local government authorities have implemented monitoring systems to mitigate landslide disasters. However, most of these systems use complex devices that are high-cost and require a constant power source to transmit data to the servers. This research designed and deployed an IoT-based landslide early warning system (EWS). The architecture is divided into three layers-Data collection, Data transmission and Data display and analysis. For the tier of data collection, an off-the-grid solar energy-powered integrated platform with various portable and low-cost sensors was built; For the tier of data transmission, mobile routers were used to support the sensor platform; In terms of data display and analysis, research provided an open architecture to analysis data and proposed a method for predicting landslides with multiple indicators. The framework is tested, extended and tuned by the model test. Results presented accurate predictions, all warning times are before the occurrence of the landslide. Then the proposed EWS was put into an embankment slope in Fukuoka, Japan by considering geological conditions and sensor suitability. This research qualitatively guarantees the accuracy of landslide predictions while operating in a low-cost, sustainable manner. It presents how IoT-based EWS can generate a positive impact on disaster mitigation work.
