We address the problem of continuously observing and forecasting long-term semantic activities of a first-person camera wearer: what the person will do, where they will go, and what goal they are seeking. In contrast to prior work in trajectory forecasting and short-term activity forecasting, our algorithm, DARKO, reasons about the future position, future semantic state, and future high-level g...

The increasing use of location-aware devices has led to an increasing availability of trajectory data. As a result, researchers devoted their efforts to developing analysis methods including different data mining methods for trajectories. However, the research in this direction has so far produced mostly isolated studies and we still lack an integrated view of problems in applications of trajec...

for some parameter 0 < ε 1 and some mappings b :R × R → R and g :R ×Rk → R . Under reasonable conditions on b and g, it is clear that as the parameter ε goes to zero, the first component X̂ε(t) of the perturbed system (1.1) converges to the constant first component x of the unperturbed system, uniformly with respect to t in any bounded interval [0, T ], with T > 0. But in applications that is mo...

In iterative learning control (ILC), a common assumption is that the initial states in each repetitive operation should be inside a given ball centered at the desired initial states which may be unknown. This assumption is critical to the stability analysis, and the size of the ball will directly affect the final output trajectory tracking errors. In this paper, this assumption is removed by us...

The effects of auditory information on 4-month-old infants' perception of trajectory continuity.

Detecting stops is an important task in trajectory analysis. Stops can reveal interesting aspects of a moving object behavior such as its daily routine, bottlenecks in traffic jams, or visiting times of touristic places. In order to record those traces, trajectories must be sampled and, in some cases, post-processed. This process from collecting raw data to storing them may vary according to th...

Previous studies on movement control modulated target size or distance in order to investigate the mechanism underlying control strategies. While these elucidated the contribution of targets in the control, how trajectory itself influences movement strategy has received little attention. Here, using event-related fMRI, we examined neural processes of trajectorybased movement control as well as ...

The success of the Genesis spacecraft, as well as the current Artemis mission, continue to generate interest in expanding the trajectory options for future science and exploration goals throughout the solar system. Incorporating multi-body dynamics into the preliminary design can potentially offer flexibility and influence the maneuver costs to achieve certain objectives. In the current analysi...

We derive a near-time-optimal trajectory for wheeled mobile robots (WMRs) satisfying the following: 1) initial and final postures/velocities as well as 2) battery voltage and armature current constraints, under assumptions of simplified dynamics and constant translational/rotational velocity sections. We use a simplified dynamic model for WMRs neglecting inductances of motor armatures and divid...

projected approach. Note that the actual k-space trajectory follows well with the nominal one, indicating eddy current is not a problem for our design on our scanner. Figure 1: (a) Nonselective spiral (SPINS) trajectory. (b) Output trajectory in the proposed joint design for the cube excitation. The proposed joint design selective traverses regions in the k-space that need high energy depositio...
