Abstract:

A method for conducting leeway field experiments to establish the drift properties of small objects (0.1–25 m) is described. The objective is to define a standardized and unambiguous procedure for condensing the drift properties down to a set of coefficients that may be incorporated into existing stochastic trajectory forecast models for drifting objects of concern to search and rescue operations and other activities involving vessels lost at sea such as containers with hazardous material. An operational definition of the slip or wind and wave-induced motion of a drifting object relative to th

Abstract:

During the 2011 Great East Japan earthquake occurring at the North–East pacific region, serious secondary disasters caused by collision of drifting containers or ships occurred in various structures when tsunami came. Drifting objects including large ships and tankers come in and out of ports in Japan. Disaster deterioration caused by drifting objects during earthquake and tsunami has become another problem. In this study, it is assumed that a large drifting ship collides with a large-span bridge in the gulf line during a tsunami. To investigate the impact behavior of the bridge during collisi

Abstract:

The importance of drifting objects to small juvenile pelagic fish was investigated off the coast of New South Wales, Australia. Distance-related and temporal patterns in the distribution of clumps of drifting algae were investigated with 5000 m2 transects at five distances from shore (0.1, 0.5, 1, 5 and 10 km), two to three times per season for 2 years. Juvenile fish associated with drift algae were collected. Clumps of algae, predominantly Sargassum spp., were most abundant in spring, which coincided with the highest abundance of alga-associated post-flexion juvenile fish. Drift algae were al

Abstract:

When humans view a moving object, the spatial lag in perception expected from neural delays may be partially corrected by motion mechanisms biasing perceived position. The drifting-Gabor illusion seems to support this view: the perceived location of a static envelope filled with a moving pattern is shifted in the direction of motion. To test whether this shifting mechanism also extrapolates the position of moving displacing objects, we compared the perceptual position shift for drifting versus displacing Gabors when the motion is toward the fovea and when the motion is away from the fovea.

Abstract:

In Great East Japan Earthquake of 2011, debris entrained within the incoming tsunami waves was responsible for widespread infrastructure damage (Chock et al., 2011). The presence of debris within the inundating wave needs to be taken into consideration; however, few methodologies and tools exist to estimate debris hazards. Therefore, one option to evaluate the behavior of drifting debris is using numerical models. Currently, the particle method, which is a meshless analysis method, is expected to be utilized for analyzing the behavior of drifting objects (Goaseberg et al., 2017). However, the

Along with the 2011 Great East Japan Earthquake (Mw 9.0), a huge tsunami exceeding a maximum wave height of 15 m occurred. Many people and objects were destroyed and drifted by the tsunami. In addition, these debris were transported to various places that could not be predicted, resulting in significant secondary damage and increase in the number of missing. Therefore, in order to reduce the amount of damage, it is important to predict the behavior and landing points of person after set adrift in a tsunami. The best way to increase the rescue rate is to predict in advance the area that people

Abstract The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a “dying” pulsar, where radio emission ceases entirely. Here we report the discovery of a long-period pulsar, PSR J0452−3418, from the ongoing Southern-sky MWA Rapid Two-meter pulsar survey. The pulsar has a rotation period of ∼1.67 s and a dispersion measure of 19.8 pc cm−3, and it exhibits both quasiperiodic nulling and subpulse drifting. Periodic nulling is uncommon, reported in only <1% of the pulsar population, with even a smaller fraction s

The characteristics of a secondary disaster are not well known with respect to the drift-impact by storm surge or tsunami.

In this study, we numerically simulated the breakaway-drift-impact process of a container due to break waves using LS-DYNA, and additionally examined the applicability of the model.

Abstract:

Multi-object tracking (MOT), especially by using a moving monocular camera, is a very challenging task in the field of visual object tracking. To tackle this problem, the traditional tracking-by-detection-based method is heavily dependent on detection results. Occlusion and mis-detections will often lead to tracklets or drifting. In this paper, the tasks of MOT and camera motion estimation are formulated as finding a maximum a posteriori (MAP) solution of joint probability and synchronously solved in a unified framework.

Abstract The two-way Lagrangian particle-tracking model (PTM) is proposed for specifying sources of objects drifting with random-walk processes on the sea surface. First, to determine object source candidates, modeled particles are released from the point (hereafter, “receptor”) where an observer finds the objects using a backward-in-time PTM with modeled ocean currents of which directions are reversed in sign. Second, the modeled particles are released from these source candidates in a forward-in-time PTM using ocean currents originally computed in hydrographic models. Third, the source candi

There is concluded that both wind-driven and geostrophic currents at the sea surface should be accounted for forecasting of drift for buoys or any floating objects.

The issue delves into and extends across the sea by exploring critical art practices and methodologies at the intersections of performance art, new media and site-specific/installation art, that integrate ocean, waves, currents, tides, coasts, depths, sea objects/vessels or environmental conditions as vital agents of the artwork. It presents nine articles by artists and scholars whose art practice and research engages with performative, embodied, participatory and technological aspects of the sea by integrating processes of drifting, floating, standing, recording, transmitting and mapping, whi

Abstract:

It is conjectured that the relative frequency of streaming vs bouncing percepts yielded by two objects drifting toward and past one another reflects the relative ‘strength’ of the underlying ‘continuity’ and ‘discontinuity’ motion vectors in the stimulus. The frequency of the two perceptual states should then be predictable from the relative effective contrast of these components which, in turn, is governed by the relative speed sensitivity and spatiotemporal integration range of the underlying sensors. Three distinct experiments were run to test this hypothesis. Percentage bouncing (%B) was a

Abstract:

Computing global motion direction of extended visual objects is a hallmark of primate high-level vision. Although neurons selective for global motion have also been found in mouse visual cortex, it remains unknown whether rodents can combine multiple motion signals into global, integrated percepts. To address this question, we trained two groups of rats to discriminate either gratings (G group) or plaids (i.e., superpositions of gratings with different orientations; P group) drifting horizontally along opposite directions. After the animals learned the task, we applied a visual priming paradig

Abstract:

Accurate and responsive 3D tracking enables interactive and context-aware workspaces, including mixed reality 3D interfaces and collaborative tangible interactions. However, limitations of current tracking mechanisms - line-of-sight occlusion, drifting errors, small working volumes, or instrumentation that requires maintenance - ultimately restrict their adoption. This paper introduces MagDesk, an interactive tabletop workspace capable of real-time 3D tracking of passive magnets embedded in objects. Using a sensing array of 112 low-cost magnetometers underneath a table, our custom-designed sig

Abstract:

Perhaps the central question in action theory is this: what ingredient of bodily action is missing in mere behavior? But what is an analogous question for mental action? I ask this: what ingredient of active, goal-directed thought is missing in mind-wandering? My answer: attentional guidance. Attention is guided when you would feel pulled back from distractions. In contrast, mind-wandering drifts between topics unchecked. My unique starting point motivates new accounts of four central topics about mental action. First, its causal basis. Mind-wandering is a case study that allows us to tease ap

Abstract:

Since the mid-1990s, drifting Fish Aggregating Devices (dFADs), artificial floating objects designed to aggregate fish, have become an important mean by which purse seine fleets catch tropical tunas. Mass deployment of dFADs, as well as the massive use of GPS buoys to track dFADs and natural floating objects, has raised serious concerns for the state of tropical tuna stocks and ecosystem functioning. Here, we combine tracks from a large proportion of the French GPS buoys from the Indian and Atlantic oceans with data from observers aboard French and Spanish purse seiners and French logbook data

Эти представления об условиях развития и распространения селевых процессов отражены в Российских нормативных документах, определяющих состав инженерных изысканий для строительства: в них как селеопасные и потенциально селеопасные районы выделены только горные территории, а равнинные и холмистые территории показаны как не селеопасные. Таким образом, селевые риски при проектно-изыскательских работах как на большей части территории России, так и в мировой практике, не учиты

Abstract:

Visual tracking of humans or objects in motion is a challenging problem when observed data undergo appearance changes (e.g., due to illumination variations, occlusion, cluttered background, etc.). Moreover, tracking systems are usually initialized with predefined target templates, or trained beforehand using known datasets. Hence, they are not always efficient to detect and track objects whose appearance changes over time. In this paper, we propose a multimodal framework based on particle filtering for visual tracking of objects under challenging conditions (e.g., tracking various human body p

Abstract:

Abstract Interstellar objects (ISOs), the parent population of 1i/‘Oumuamua and 2i/Borisov, are abundant in the interstellar medium of the Milky Way. This means that the interstellar medium, including molecular-cloud regions, has three components: gas, dust, and ISOs. From observational constraints of the field density of ISOs drifting in the solar neighborhood, we infer that a typical molecular cloud of 10 pc diameter contains some 1018 ISOs. At typical sizes ranging from hundreds of meters to tens of kilometers, ISOs are entirely decoupled from the gas dynamics in these molecular clouds. Her
