This paper investigates the formation control of connected autonomous vehicle (CAV) platoons moving in multi lanes using distance-based formation control techniques based on rigid graphs and V2V communication. A hierarchical architecture is proposed to decompose the cooperative control into velocity planning...
Distance-based formation of groups of mobile robots provides an alternative focus for motion coordination strategies respect to the standard consensus-based formation strategies. However, the setup formulation introduces non rigidity problems, multiple formation patterns that verify the distance constraints or...
This study deals with the formation control problem of swarm robots using position sensitive detector (PSD) proximity distance sensors based on light-emitting diodes (LEDs). These proximity distance sensors are lightweight and quickly responsive, and are expected to enhance the mobility and flexibility...
A common technique is based on the radial distance measured from a central point in the region to each pixel (x(n), y(n)) on the boundary. Generally, the centroid (xc, yc) is used as the central point and the radial distance sequence (15.18)d(n)=[x(n)-xc]2+[y(n)-yc]2n=0...
Based on the tests, the main parameters influencing the process control could also be identified. The main influences are the hatch distance, the scanning speed, and the layer thickness with their respective linear effects. Furthermore, the complexity of the process interrelationships, which are ...
As used herein, the term “object” is used according to its broadest meaning and may include solid, liquid, gas, and plasma-based things. The sensor device 1 includes a number of cells 2 arranged to form an array 3 and each constituting an elementary sensor. The simplicity of the ...
The sample size was determined using a-priori power analysis with the G-Power program128. Based on the within-subject design of the study, a power of 0.95, an alpha level of 0.05, and an effect size of 0.5, a minimum sample size of 54 was required. Data collection involved a larger ...
In this work, we propose a new technique to help the social distance maintenance based on augmented reality (AR). Motivated by the education in the significance of social distance for pandemic prevention, where a dedicated video is sometimes played to show the spread of the respiratory droplets ...
The distance-based phylogenetic method is fast and remains the most popular one in molecular phylogenetics, especially in the big-data age when researchers often build phylogenetic trees with hundreds or even thousands of leaves. A distance-based method has two components: the evolutionary distance ma...
A movement distance calculation device includes: a first movement distance calculation unit which calculates a first movement distance of a movable body based on plural rotation spe
