The advances in mobile computing and social networking services enable people to probe the dynamics of a city. In this paper, we address problem detecting describing traffic anomalies using crowd sensing with two forms data, human mobility media. Traffic are caused by accidents, control, protests, sport events, celebrations, disasters other events. Unlike existing traffic-anomaly-detection methods, identify according drivers' routing behavior on an urban road network. Here, detected anomaly...
Ultraviolet radiation (UVR) is a risk factor for the development of ocular disease in humans, including acute photokeratitis, chronic corneal spheroidal degeneration, and cataract formation. This report describes lesions seen 21 mice chronically exposed to UVR as part skin carcinogenicity study. All globes were affected varying degrees. The primary lesion, not previously reported UVR-exposed mice, was marked loss keratocytes relative age-matched controls. Secondary included stromal thinning,...
We address the problem of real-time navigation in dynamic environments for car-like robots. present an approach to identify controls that will lead a collision with moving obstacle at some point future. Our generalizes concept velocity obstacles, which have been used among and takes into account constraints robot. use this formulation find allow free environments. Finally, we demonstrate performance our algorithm on simulated robot obstacles.
We introduce a novel, online method to predict pedestrian trajectories using agent-based velocity-space reasoning for improved human–robot interaction and collision-free navigation. Our formulation uses velocity obstacles model the trajectory of each moving in robot’s environment improves motion by adaptively learning relevant parameters based on sensor data. The resulting agent is computed statistical inferencing techniques, including combination ensemble Kalman filters maximum-likelihood...

Urban transportation is increasingly studied due to its complexity and economic importance. It also a major component of urban energy use pollution. The importance this topic will only increase as urbanization continues around the world. A less researched aspect refueling behavior drivers. In paper, we propose step toward real-time sensing citywide petrol consumption. We reported trajectories from fleet GPS-equipped taxicabs detect gas station visits, measure time spent, estimate overall...
This paper presents LQG-Obstacles, a new concept that combines linear-quadratic feedback control of mobile robots with guaranteed avoidance collisions obstacles. Our approach generalizes the Velocity Obstacles [3] to any robotic system linear Gaussian dynamics model. We integrate Kalman filter for state estimation and an LQR controller into closed-loop model which higher-level objective is "control input". then define LQG-Obstacle as set objectives result in collision high probability....

Our key contributions are efficient techniques dynamic coupling discrete vehicle simulation with aggregated behavior demonstrate flexibility scalability our interactive visual technique on extensive...
SUMMARY Intraocular pressure ( iop ) was measured, using applanation tonometry, in both eyes of 20 horses after topical application 0.5% proparacaine to the cornea. Ultrasonic pachymetry used measure central, mid-peripheral, and peripheral corneal thickness ct all 4 quadrants 25 horses. All measurements were repeated auriculopalpebral nerve block, sedation by iv administration xylazine, or combination block sedation.

To determine the feasibility, safety, and effectiveness of an episcleral or deep scleral lamellar sustained release cyclosporine (CsA) device in a naturally occurring animal model uveitis.A two-compartment perfusion chamber was used to assess vitro human equine permeability fluorescein, dexamethasone-fluorescein, CsA. A biodegradable, matrix-reservoir CsA implant designed, rates were determined vitro. Tissue levels measured eyes with implant. Horses recurrent uveitis (ERU) received implants...

There exists a vast amount of geographic information system (GIS) data that model road networks around the world as polylines with attributes. In this form, are insufficient for applications such simulation and 3D visualization-tools which will grow in power demand sensor become more pervasive governments try to optimize their existing physical infrastructure. paper, we propose an efficient method enhancing map from GIS database create geometrically topologically consistent be used real-time...

'Virtualized traffic' reconstructs and displays continuous traffic flows from discrete spatio-temporal sensor data or procedurally generated control input to enhance a sense of immersion in dynamic virtual environment. In this paper, we introduce fast technique reconstruct in-road measurements for interactive 3D visual applications. Our algorithm estimates the full state flow sparse (or procedural input) using statistical inference method continuum model. This estimated then drives an...

Traffic congestion is a perpetual challenge in metropolitan areas around the world. The ability to understand traffic dynamics thus critical effective control and management. However, estimation of conditions over large-scale road network has proven be challenging task for two reasons: first, are intrinsically stochastic; second, availability quality data vary great extent. Traditional monitoring systems that exist mostly on major roads highways insufficient recover an entire network. Recent...
