ABSTRACT Geotechnical site characterization is the process of collecting geophysical and geospatial characteristics about the surface and subsurface to create a 3-dimensional (3D) model. Current Robot Operating System (ROS) world models are designed primarily for navigation in unknown environments; however, they do not store the geotechnical characteristics requisite for environmental assessment, archaeology, construction engineering, or disaster response. The automotive industry is researching High Definition (HD) Maps, which contain more information and are currently being used by autonomous vehicles for ground truth localization, but they are static and primarily used for navigation in highly regulated infrastructure. Modern site characterization and HD mapping methods involve survey engineers working on-site followed by lengthy post processing. This research addresses the shortcomings for current world models and site characterization by introducing Site Model Geospatial System

After hurricanes and other disasters, it is becoming more common for people to fly drones to record the damage and post videos on social media. Those videos are a resource for rapid damage assessment. By using artificial intelligence, researchers are developing a system that can automatically identify buildings and make an initial determination of whether they are damaged and how serious that damage might be
For wealthy countries like Switzerland, having a dense network of earthquake monitoring stations is a matter of course. This is not the case in less developed countries and on the floor of the world’s oceans. While poorer regions lack the money for the necessary number of sensors, the oceans require complex systems that can reliably measure minimal pressure changes at depths of thousands of meters and bring the data signals to the surface
An oil spill refers to the accidental or deliberate release of petroleum or other petroleum-based products into the environment. These spills can occur on land or in water bodies, such as oceans, rivers, or lakes, and can have devastating impacts on the environment, wildlife, and human health. Oil spills can harm aquatic and terrestrial ecosystems by contaminating water and soil, and by affecting the food chain. They can also cause economic losses, such as the loss of fisheries, tourism, and property values. Cleaning up oil spills can be a difficult and expensive process, and the effectiveness of the response can depend on various factors, such as the type and amount of oil spilled, weather conditions, and proximity to sensitive ecosystems. Preventing oil spills is critical to minimizing their impacts. This can be achieved through measures such as regular maintenance of oil transport and storage facilities, the use of double- hulled tankers, and the implementation of emergency response

This paper presents a simulation study of hydrogen leakage from an onboard hydrogen supply system in open, closed, and semi-closed spaces. The simulations investigate the effects of environmental factors and conditions such as obstacles on the diffusion process of hydrogen leaks. The results show that when hydrogen gas leaks, the direction of the leak determines the potential risk. If the leak is directed toward the cab, the gas will accumulate in the gap between the cab and the hydrogen supply system, posing a significant risk to the driver. On the other hand, if hydrogen leaks toward the rear, a combustible cloud forms mainly behind the vehicle at a safe distance of 3.8 meters. The study also investigated the effects of wind speed, wind direction, and ambient temperature. It was found that headwinds can cause hydrogen to spread near the vehicle, increasing the risk of an accident. The paper also investigates the effect of obstacles that inhibit the horizontal diffusion of hydrogen

Advanced technology plays a vital role in search and rescue operations after natural disasters such as earthquakes. Thermal imaging equipment and sensitive listening devices are deployed to seek out signs of life. Small aerial drones could also survey otherwise inaccessible spaces, but the inherent fragility of current designs have limited their use
Thousands die or are injured each year in automobile crashes. Reducing the number of these tragedies requires reframing our approach to vehicle- and human-based transportation mobility and depends on whether the mobility industry and individual human drivers take a more aggressive approach to saving lives and preventing injuries. Bringing automated driving systems technologies into the advanced driver assist systems (ADAS) and connected vehicle space will help humans drive more safely and better prepare us for automated vehicles (AVs). Reducing Human Driver Error and Setting Realistic Expectations with Advanced Driver Assistance Systems discusses the recent Partnership for Analytics Research in Traffic Safety report which shows that ADAS can indeed work. The path forward requires combining ADAS and ADS implementation with infrastructure engineering, law enforcement, education, emergency response, and public policy, with the goal of reaching zero deaths and serious injuries.

As fossil fuels are phased out in the effort to slow global warming, we will be depending upon a reliable source of electric power more than ever. And that means blackouts caused by weather events such as hurricanes, tornadoes, and snowstorms will have increasingly serious consequences
A research team at the University of Central Florida has developed technology that could prevent electric vehicle fires, like those caused by saltwater flooding from Hurricane Ian
To make sure our buildings and infrastructure are earthquake-safe, we must understand how seismic activity affects different structures. Two major research efforts funded by the Department of Energy (DOE) seek to fill in the gaps and provide resources for researchers and engineers to study earthquakes across scales, from the initiation of seismic waves at the fault rupture site deep underground, to the interactions between shaking soil and individual structures at the surface
Innovators at the NASA Langley Research Center have developed the Multi-Layer Nuclear Thermionic Avalanche Cell (NTAC), a novel electrical generator, which transforms nuclear gamma-ray photon energy directly to electric power by liberating intra-band atomic inner shell electrons
Motorcyclists are about 29 times more likely than passenger vehicle occupants to die in a motor vehicle crash and are 4 times more likely to be injured. Safe motorcycling takes balance, co-ordination, and good judgement. As per NHTSA, per 100,000 registered vehicles motorcycle fatality and injury rate stand at 58.33 and 975 and that of passenger vehicles stand at 9.42 and 1152. With such rates of fatality and injury of motorcyclists, there is strong need for motorcycle solutions that help to minimize traffic fatalities and improve road safety scenarios. Helmets are estimated to be 37% effective in preventing fatal injuries to motorcycle riders and 41% for motorcycle passengers but there is little to no post-crash assistance available on board the motorcycles. Post-crash emergency response is time sensitive and can be broken down into a subset of activities beginning with discovery of crash, notification, and activation of emergency medical service (EMS), response time, on-scene time

Data is information that has been recorded in a form or format convenient to move or process. It is important to distinguish between data and the format. The format is a structured way to record information, such as engineering drawings and other documents, software, pictures, maps, sound, and animation. Some formats are open source, others proprietary. Regardless of the format, there are three broad types of data. Table 1 lists these types of data and provides examples. DM, from the perspective of this standard, consists of the disciplined processes and systems utilized to plan for, acquire, and provide management and oversight for product and product-related business data, consistent with requirements, throughout the product and data life cycles. Thus, this standard primarily addresses product data and the business data required for stakeholder collaboration extending through the supply chain during product acquisition and sustainment life cycle. This standard has broader application

Coastal and riverine shorelines are dynamic landscapes that change continually in response to environmental forces. The combination of static infrastructure with dynamic and diverse landscapes creates management challenges for navigation, storm damage reduction, and ecosystem health that are exacerbated during natural disasters. The U.S. Army Corps of Engineers (USACE) flood risk management (FRM) mission strives to reduce the nation's flood risk and increase resilience to disasters. FRM is inherently interdisciplinary, requiring accurate identification of environmental, physical, and infrastructure features that can reduce risk from flood and coastal storm disasters
Road traffic injuries continue to be a leading cause of death around the world. Rapid emergency response is a key factor in improving occupant outcomes. Over the past ten years, Injury Severity Prediction (ISP) models have been developed and deployed to assist in effective dispatch of emergency medical services (EMS). Prior versions of ISP have relied on driver-based scenarios that are not relevant in many of the possible autonomous vehicle (AV) contexts. This paper describes the development and validation of occupant-based ISP models that predict injury severity for specific vehicle seat positions. Models show improved predictive performance, sensitivity 80% and specificity over 95%, for front row occupants. Second row occupant models have similar specificity, but sensitivity scores dropped due to occupant heterogeneity and small sample sizes of seriously injured occupants

Scientists have developed color-changing, flexible photonic crystals that could be used to develop sensors that warn when an earthquake might strike next. The wearable, robust, and low-cost sensors can respond sensitively to light, temperature, strain, or other physical and chemical stimuli, making them a promising option for cost-effective smart visual sensing applications in a range of sectors including healthcare and food safety
Conventional forensic analyses of collision avoidance behaviours involve assigning a perception and response time (PRT) interval to a driver which precedes the onset of evasive action. This approach relies on the investigator identifying a ‘time zero’ for when to begin the PRT interval, which nominally aligns with the first moment of hazard detection. However, depending on the incident circumstances, identifying the initial moment of hazard detection poses challenges. Recent research has shown the potential of an alternative method of forensic analysis that is based on the relationship between response onset and the projected time-to-impact (TTI). Accordingly, the aim of this research is to further investigate this relationship. Twenty subjects viewed driver-perspective recordings of a simulated vehicle travelling down a major roadway past several two-way stop-controlled minor roads. At various intersections, intruding vehicles entered from the left or right. These intruders were

A recent virtual panel discussion reminded me that we ought not forget the propulsion workhorse of our industries: the good ol' diesel engine. It's sometimes easy to forget in the avalanche of EV and fuel-cell developments - quite a few detailed in this very issue - that combustion engines will continue to power the majority of on- and off-highway vehicles at least for the next decade. To further improve ICE efficiency during this powertrain-diversification process, engineers and R&D departments still are plugging away (pardon the pun) at engine and fuel advancements. “For most of the sectors of the construction industry, diesel is the technology of choice particularly for the largest construction machines and equipment,” said Allen Schaeffer, executive director of the Diesel Technology Forum, which hosted the virtual event with industry leaders. “Diesel is still evolving, and it will continue to do so in the future with even lower emissions and greater efficiency
