The Pareto front can provide valuable information on land-use planning decision by revealing the possible trade-offs among multiple, conflicting objectives. However, seeking of allocation is much more difficult than finding a unique optimal solution, especially when dealing with large-area regions. This article proposes an improved artificial immune system for multi-objective (AIS-MOLA) to tackle this challenging task. proposed AIS equipped three modified operators, namely (1) heuristic...

Global flood models (GFMs) and earth observation (EO) play a crucial role in characterising flooding, especially data-sparse, under-resourced regions of the world. However, validation studies are often limited to handful historic events do not directly assess ability these products simulate hazard—the probability that flooding will occur given location. As result, it is difficult for stakeholders decipher either or observations identify hazard make decisions mitigate flooding. Here, we...

This paper presents an in-depth case study of a real-life scenario in which bridge was rapidly 3D replicated, validating the feasibility polyurethane foam printing (PF3DP) technology solution. In terms construction materials, analyzes printability extrudability, stacking stability, and curing characteristics; equipment, foaming equipment is assembled to Mobile Construction Platform (MCP). The data processed by Context Capture software create optimize model, then sliced printed via MCP....

Traditional inundation mapping often relies on deterministic methods that offer only binary outcomes (inundated or not) based satellite imagery analysis. While widely used, these do not convey the level of confidence in classifications to account for ambiguity uncertainty, limiting their utility operational decision-making and rapid response contexts. To address limitations, we propose a probabilistic method integrates local thresholds derived from Sentinel-1 SAR images land cover data...

Satellite remote sensing has been widely used to monitor surface water, but its application in observing rapid inundation changes remains challenging. Observations relying on only one sensor could hardly achieve both high temporal and spatial resolutions. High resolution images are not frequent enough capture the fast-changing inundation, while do provide sufficient detail variations. To address this compromise for response, here we propose a new automated method estimate daily sub-pixel...

A zero-voltage switching (ZVS) technique employing a resonant-transition during interval has been explored for many years. To ensure ZVS operation, two approaches were frequently chosen, separately or mixed. One is to have enough gap on the main core. The other add an external inductor in series with transformer. However, both suffer from parasitic ringing phenomena practical circuit. generated by leakage inductance/external and stray capacitance seen transformer primary winding. It...

Heavy precipitation and storm surges often co-occur compound together to form sudden severe flooding events. However, we lack comprehensive observational tools with high temporal spatial resolution capture these fast-evolving hazards. Remotely sensed images provide extensive coverage, but they may be limited by adverse weather conditions or platform revisiting schedule. River gauges could frequent water height measurement are sparsely distributed. Riverine flood surge models, depending on...

The rugged terrain, complex landforms and uneven coverage distribution of radio waves in high-altitude mountainous areas bring great challenges to the reliable networking mobile users, especially intelligent vehicle devices. This paper mainly studies influence terrain on propagation loss infrastructure (V2I) network this environment, predicts propagating from transmitter receiver. By establishing V2I system model high altitude area, using digital elevation (DEM) database triangulated...

Abstract BACKGROUND The bites and blood sucking of bed bugs ( Cimex spp.) (Hemiptera: Cimicidae) pose a serious threat to human physical mental health. Application an effective repellent can prevent or reduce bug bites. Previous studies on screening mainly focused lectularius L. In this study, we investigated the effect two safe food additives, ethyl anthranilate (EA) butyl (BA), against hemipterus (F.), also explored role antennae mouthparts C. perception repellents. RESULTS Both EA BA had...

China's global infrastructure financing flagship, the Belt and Road Initiative (BRI) encompasses countries hosting over 60% of population one-third worldwide GDP. It is based mainly on long-term loans that will mature decades into future, timely repayments are only possible if they remain commercially viable. But despite its vast scope, little known about climate risks could imperil operations BRI projects next few decades, and, consequently, threaten their sustainability. We narrow this gap...

With the maturity of LTE network construction and increasing number college students, explosive increase in base stations users makes current environment more complex, resulting weak coverage problems networks. Good quality helps to improve perception campus users. However, it is actually found that there are still poor signals areas when using mobile networks colleges universities. Therefore, great significance analyze optimize problem. In this paper, software tools such as Huawei's drive...

With the rapid growth of economy and acceleration urbanization, scarcity land resources has become increasingly prominent, changes in use types have a hot research topic. This study takes Zhenjiang City Jiangsu Province as an example, using data from 2000, 2010, 2020, combining ArcGIS with three methods: transfer matrix, dynamic degree, standard deviation ellipse, to analyze spatiotemporal amounts past two decades. The results indicate that firstly, are cropland, construction land, forests,...

Natural disasters such as floods, forest fires, and hurricanes can cause catastrophic damage to human life infrastructure. We focus on response caused by both river water flooding storm surge. Using models for surge simulation flood extent prediction, we generate forecasts about areas likely be highly affected the disaster. Further, overlay results with information traffic incidents correlate other data modality. present these in a modularized, interactive map-based visualization, which help...

Surface water has been monitored by using remote sensing techniques for decades. Nevertheless, remotely sensed images inevitably compromise temporal and spatial resolution, which limits the urgent application in sudden flooding response. Images with a high resolution cannot be acquired processed frequently to monitor fast-evolving flood events that could change dramatically within few days. To address such challenge, this paper presents method un-mix surface from MODIS derived indices,...
