Recent studies indicate that the rates of sea level rise (SLR) along U.S. mid‐Atlantic coast have accelerated in recent decades, possibly due to a slowdown Atlantic Meridional Overturning Circulation (AMOC) and its upper branch, Gulf Stream (GS). We analyzed GS elevation gradient obtained from altimeter data, Florida Current transport cable measurements, North Oscillation (NAO) index, coastal 10 tide gauge stations Chesapeake Bay coast. An Empirical Mode Decomposition/Hilbert‐Huang...

This paper introduces a dataset gathered entirely in urban scenarios with car equipped one stereo camera and five laser scanners, among other sensors. One distinctive feature of the present is existence high-resolution images grabbed at high rate (20 fps) during 36.8 km trajectory, which allows benchmarking variety computer vision techniques. We describe sensors employed highlight some applications could be benchmarked using work. Both plain text binary files are provided, as well...

In previous works, we reported a method experimentally obtain an optimized kinematic model for tracked based on boundedness instantaneous centers rotation...

Gas distribution modelling constitutes an ideal application area for mobile robots, which - as intelligent gas sensors offer several advantages compared to stationary sensor networks. In this paper we propose the Kernel DM+V algorithm learn a statistical 2-d model from sequence of localized measurements. The does not make strong assumptions about sensing locations and can thus be applied on robot that is primarily used monitoring, also in case treats density estimation problem. contrast most...

Over 360 million people worldwide suffer from disabling hearing loss. Most of them can be treated with aids. Unfortunately, performance aids and the benefit obtained using vary widely across users. Here, we investigate reasons for such variability. Sixty-eight hearing-aid users or candidates were fitted bilaterally nonlinear standard procedures. Treatment outcome was assessed by measuring aided speech intelligibility in a time-reversed two-talker background self-reported improvement ability....

Over 30 years of hydrographic data from the northern Chile (18°S–24°S) upwelling region are used to calculate surface and subsurface seasonal climatology extending 400 km offshore. The interpolated a grid with sufficient spatial resolution preserve cross‐shelf gradients then presented as means within four seasons: austral winter (July‐September), spring (October‐December), summer (January‐March), fall (April‐June). Climatological monthly wind forcing, temperature, sea level three coastal...

One of the major disadvantages use Metal Oxide Semiconductor (MOS) technology as a transducer for electronic gas sensing devices (e-noses) is long recovery period needed after each exposure. This severely restricts its usage in applications where concentrations may change rapidly, mobile robotic olfaction, allowing sensor forces robot to move at very low speed, almost incompatible with any practical operation. paper describes design new e-nose which overcomes, great extent, such limitation....

Metal Oxide Semiconductor (MOX) gas transducers are one of the preferable technologies to build electronic noses because their high sensitivity and low price. In this paper we present an approach overcome a certain extent major disadvantages: slow recovery time (tens seconds), which limits suitability applications where sensor is exposed rapid changes concentration. Our proposal consists exploiting double first-order model MOX-based from steady-state output anticipated in real given...

This work addresses range-only SLAM (RO-SLAM) as the Bayesian inference problem of sequentially tracking a vehicle while estimating location set beacons without any prior information. The only assumptions are availability odometry and range sensor able identifying different beacons. We propose exploiting conditional independence between position distributions each beacon within Rao-Blackwellized Particle Filter (RBPF) for maintaining independent Sum Gaussians (SOGs) beacon. Unlike other...

Range-only SLAM (RO-SLAM) represents a difficult problem due to the inherent ambiguity of localizing either robot or beacons from distance measurements only. Most previous approaches this employ non-probabilistic batch optimizations delay initialization new within probabilistic filter until good estimate is available.

Rao—Blackwellized particle filters (RBPFs) are an implementation of sequential Bayesian filtering that has been successfully applied to mobile robot simultaneous localization and mapping (SLAM) exploration. Measuring the uncertainty distribution estimated by a RBPF is required for tasks such as information gain-guided exploration or detecting loop closures in nested environments. In this paper we propose new measure takes both path map into account. Our approach relies on entropy expected...
