In a dyadic informed forager task, chimpanzees (Pan troglodytes) are known to exploit the knowledge of informed subordinates; however, the behavioral mechanisms they employ are unknown. It is tempting to interpret outcome measures, such as which individual obtained the food, in a cognitively richer way than the outcomes may justify. We employed a different approach from prior research, asking h...

Evolutionary patterns of intrinsic caudal musculature in ray-finned fishes show that fine control of the dorsal lobe of the tail evolved first, followed by the ability to control the ventral lobe. This progression of increasing differentiation of musculature suggests specialization of caudal muscle roles. Fine control of fin elements is probably responsible for the range of fin conformations ob...

In this paper, an unscented Kalman filter (UKF) for curvilinear motions in an interacting multiple model (IMM) algorithm to track a maneuvering vehicle on a road is investigated. Driving patterns of vehicles on a road are modeled as stochastic hybrid systems. In order to track the maneuvering vehicles, two kinematic models are derived: A constant velocity model for linear motions and a constant...

The proposed method allows evaluating an automobile handling with or without accounting withdrawal, various types of drive wheels and steering using partial acceleration. Determination lateral tangential reactions on tire while turning in view slip more accurate maneuverability, stability handling. vehicle total angular accelerations during its driving into rotation withdrawal developing vehicl...

The paper presents the design of a hybrid controller used to control the movement of a ship in different operating modes, thereby improving the performance of basic maneuvers. This task requires integrating several operating modes, such as maneuvering the ship at low speeds, steering the ship at different speeds in the course or along the trajectory, and stopping the ship on the route. These mo...

Background. This study aimed to describe how people move about in manual wheelchairs (MWCs) during everyday life by evaluating bouts of mobility or continuous periods of movement. Methods. A convenience sample of 28 MWC users was recruited. Participants' everyday mobility was measured using a wheel-mounted accelerometer and seat occupancy switch for 1-2 weeks. Bouts of mobility were recorded an...

Spatial Spectrum Estimation with a Maneuvering Sensor Array in a Dynamic Environment by Jonathan L. Odom Department of Electrical and Computer Engineering Duke University

This paper is devoted to the method of choosing a scheme for placing navigation signs on sections inland waterways ensure vessels with given level risks. The methods used are known from theory probability and mathematical statistics assessment risks, which proposed be performed by stochastic methods, estimating dis-placement center vessel's size variability maneuvering lane. It shown that accor...

Abstract The detection and tracking of small weak maneuvering radar targets in complex electromagnetic environments is still a difficult problem to effectively solve. To address this problem, paper proposes dynamic programming tracking-before-detection method based on long short-term memory (LSTM) network (LSTM-DP-TBD). With the predicted target motion state provided by LSTM network, transition...
