A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy
Journal of Field Robotics, EarlyView.ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers
River Research and Applications, EarlyView.ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Small Methods, EarlyView.This study introduces an in situ UV torsional force spectroscopy method to track how polymers harden under UV light. The technique maps stiffness and energy loss beneath the surface in real time. It reveals how cross‐linking develops and identifies regions with different mechanical behavior, helping optimize UV curing processes in polymer materials ...

Wildlife Biology, EarlyView.We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

Evaluation of Rumble Stripes on Low-Volume Rural Roads in Iowa—Phase II Final Report, November 2011 [PDF]
, 2011 Single-vehicle run-off-road crashes are the most common crash type on rural two-lane Iowa roads. Rumble strips have proven effective in mitigating these crashes, but the strips are commonly installed in paved shoulders on higher-volume roads that are ...

Enhancement of synthetic jets by means of an integrated valve-less pump Part II. Numerical and experimental studies [PDF]
, 2005 The paper studies the performance of the new fluid jet actuator based on the novel principle of the generation of fluid jet, which has been presented in [Z. Travnicek, A.I. Fedorchenko, A.-B.

The effectiveness of delineation treatments [PDF]
, 2005 A literature review undertaken for Transit NZ has found that delineation has a significant effect on driver behaviour with, for example, shoulder rumble strips reducing run-off-theroad crashes by between 22% and 80% (average of 32% for all crashes and 44%

Animal Conservation, EarlyView.A diagram of the integrated species distribution model of river otter intensity of use. Three types of data (latrine detections, roadkill detections, and detection/nondetection surveys) are linked by different observation processes to the same underlying intensity of use.

Multiscale Residual Convolution Neural Network and Sector Descriptor-Based Road Detection Method
IEEE Access, 2019 Road detection is a focus of research in the field of remote sensing image analysis. This task is normally difficult due to the complexity of the data, which are heterogeneous in appearance with large intra-class and lower inter-class variations that ...

Contributions to predicting contaminant leaching from secondary materials used in roads [PDF]
, 2004 Slags, coal ashes, and other secondary materials can be used in road construction. Both traditional and secondary materials used in roads may contain contaminants that may leach and pollute the groundwater.
