Development of potholes from cracks in flexible pavements
… The development of cracks and the formation of potholes on road surface are widespread problems in road construction and maintenance. The objective of this study is to develop mathematical models to compute stresses and deflections associated with the cracks in flexible pavement and the …

Evaluating Surface Area-Basin Volume Relationships for Prairie Potholes
… between surface area and volume of prairie potholes provides a simple method to estimate changes in water storage across the landscape. Applications include better prediction of floods and improved design for wetland restoration. Length, width, depth, surface area, and volumes were surveyed …

Ecological Relationships of Breeding Blue-winged Teal to Prairie Potholes
<p>Ecology and behavior of breeding blue-winged teal (Anas discors) were studied in northeastern Day County, South Dakota in 1965 and 1966. Breeding pair use of the wetland habitat and importance of Type 1 ponds in the wetland complex were evaluated. Pair densities of 30.7 and 33.0 per square mile …

Modelling of the effects of potholes on motor vehicle structures
… the effects of the impulses induced by potholes on motor vehicle structures. MATLAB computer package was used to develop a computer program to carry out the tasks. This was done with a view to make recommendations in the nature and frequency of maintenance or replacement of vulnerable …

Monitoring tracer stones through the potholes of Fall Creek Gorge near Williamsport, Indiana
… record deposition and erosion of sediment within potholes. Tracer clasts introduced upstream of the potholes were transported through the reach over a period of a few weeks: we see no evidence for individual coarse sediment particles having long residence times within potholes. Initial transport …

Federated learning-based 3D pothole detection, evaluation, and routing for smart transportation
… driving conditions. Auto damages caused by potholes can add up to thousands of dollars per vehicle. Besides, pothole resolution is one of the most expensive street maintenance strategies. Most cities have established social data networks (i.e., Open Data KC 311 in Kansas City) for residents …

Geo-Locating Tweets with Latent Location Information
… conducted experiments with tweets (e.g., about potholes), and found significant improvement in disambiguating tweet locations using a ML algorithm along with the Stanford NER. Adding state information predicted by our classifiers increased the possibility to find the state-level geo-location …

Analyzing the use of radio frequency identification (RFID) on the container industry
… We set forth the potential benefits and the potholes that could make at the moment such a solution to fail, if the industry does not try to repair the systems faults and shows overconfidence in the proposed technology.

Line Detection and Lane Following for an Autonomous Mobile Robot
… the vehicle encounters obstacles, painted potholes, a ramp and a sand pit. The success of the robot is usually determined by the software controlling it. Johnny-5 was one of three vehicles entered in the 2004 competition by Virginia Tech. This paper presents the vision processing software …

Deploying drones for autonomous detection of pavement distress
… draw on crowd-sourced mechanisms to identify potholes. It builds on other recent technological solutions that employ remote sensing to collect and interpret data on pavement health. The results from this mission will be visualized through a web platform that can not only aid cities in …

Event Detection in the Terrain Surface
… flatness from which localized events such as potholes in the terrain surface can be found and is an important tool in pavement health monitoring and vehicle performance inspection. Repeated detection of terrain surfaces over an extended period of time can be used by highway engineers for long …

Road Pothole Detection Method Using Built-in Sensors In Smartphone
… is installed on vehicle as a tool to detect potholes on the road. The data collected and pre-processed by smartphone is then analysed to obtain the result. The history and status of pothole detection study is firstly discussed. The traditional pothole detection method has two disadvantages: …

Late Proterozoic bedrock geology and its influence on neogene littoral marine diamondiferous trapsites, MA1-Sperrgebiet, Namibia
… stillstands. Diamond trapsites in the form of potholes and gullies are incised into palaeo platforms formed during the sea-level stillstands. The marine erosion palaeo-platforms have been cut into the predominantly siliciclastic rocks of the Gariep Belt. The Late Proterozoic Gariep Belt is …

Lessons Learned in Energy Efficiency of Mini-Split HVAC Systems in Affordable Housing
… housing is not without cracks and potholes. Many building stakeholders have pointed to the discrepancies that exist between simulated and measured efficiency results, where some have called it a post-occupancy gap, others have called it an energy efficiency information gap. The …

Ground-Dwelling Arthropod Community Structure of Saskatchewan's Agroecosystems and Seeded Grasslands
… communities. To assess the influence of prairie potholes, two transects were established per sampled field, with one starting at the field margin while the other originated from a prairie pothole edge. Principal coordinate analysis and generalized linear models were employed to characterize …

Delineation of Surface Water Features Using RADARSAT-2 Imagery and a TOPAZ Masking Approach over the Prairie Pothole Region in Canada
… to delineating the surface water area of Prairie potholes on an ongoing and cost-effective basis. Optical satellite imagery is able to detect surface water but only under cloud-free conditions, a substantial limitation for operational monitoring of surface water variability. However, as an active …
