Summary Objectives: This article discusses our new Path-Graph approach for the interactive Live-Wire segmentation method in 2D applied to pre-segmented data. Furthermore, we examine whether or not the Live-Lane extension provides advantages in combination with pre-segmentation. Methods: We automatically over-segment the image data in a preprocessing step, using region growing with an automatic seed point generation. The Live-Wire algorithm is applied on this mosaic data by using the outlines of the homogeneous regions as the basis for graph building. We present a new definition of this underly

Streszczenie:

Trajectory planning is a classic problem in robotics, with different approaches and optimisation objectives documented in the literature. Most of the time, the path is assumed, i.e., pre-defined, and optimisation consists of finding the timing of motion under a number of constraints. The focus of this work is on the minimum-time manoeuvring of robotic manipulators. A nonlinear optimal control approach is proposed that does not require the provision of either a pre-defined path or a pre-defined control structure and allows the inclusion of dynamic constraints. The solution (path and timing of m

Abstract This study investigates the use of four common path planning algorithms - RRT (Rapidly-Exploring Random Tree), Dijkstra, A*, and ACO (Ant Colony Optimization) - for autonomous endpoint search in pre-defined grid mazes. Path planning is a crucial problem in robot navigation, involving the ability to find optimal paths with the minimum running time in complex environments. In this research, it firstly introduces the basic principles and mechanisms of each algorithm. RRT is a random sampling-based algorithm that explores the search space by generating a tree-like structure randomly. Base

In the multi-agent path-finding (MAPF) problem, the task is to find a plan for moving a set of agents from their initial locations to their goals without collisions. Following this plan, however, may not be possible due to unexpected events that delay some of the agents. We explore the notion of k-robust MAPF, where the task is to find a plan that can be followed even if a limited number of such delays occur. k-robust MAPF is especially suitable for agents with a control mechanism that guarantees that each agent is within a limited number of steps away from its pre-defined plan.

This is an extension of previous work which used an artificial neural network with a back-propagation algorithm and a lookup table to find the inverse kinematics for a manipulator arm moving along pre-defined trajectories. The work now described shows that the performance of this technique can be improved if the back-propagation is made to be adaptive. Also, further improvement is obtained by using the whole workspace to train the neural network rather than just a pre-defined path. For the inverse kinematics of the whole workspace, a comparison has also been done between the adaptive back-prop

A pre-defined path is designed, and the rover is programmed to move the rover in the desired path. The Arduino IDE software tool is used to write the program and the program is being dumped into the microcontroller. A gripper with two arms is used to pick and place objects that are functionally similar to a hand.

An active sound profiling (ASP) control algorithm based on the command FxLMS with an additive feedforward enhancement is suggested to overcome the limited performance to track a pre-defined target sound in a car cabin when an electronic sound generator (ESG) attached to a cowl panel of a car was adopted as a secondary actuator. As the uncertainty of the secondary path including the ESG-cowl pair was increased especially at higher frequencies, the tracking performance of a pure ASP algorithm was limited. The feedforward enhancement was added to the pure ASP algorithm to allow a robust tracking

We consider the problem of finding a rectilinear path between two designated points in the presence of rectilinear obstacles subject to various optimization functions in terms of the number of bends and the total length of the path. Specifically we are interested in finding a minimum bend shortest path, a shortest minimum bend path or a least-cost path where the cost is defined as a function of both the length and the number of bends of the path. We provide a unified approach by constructing a path-preserving graph. guaranteed to preserve all these three kinds of paths and give an O(K+e log e)

Empire is regularly defined as a political unit of large extent controlling a number of territories and peoples under a single sovereign authority. Of the three criteria, only one, sovereign authority, is quantified. In the early sixteenth century, maritime Europe, starting on its own path to empire, encountered large imperial regimes across the globe — the Ottoman, Safavid, Mughal, Ming, Aztec, and Inca — each of which had an identifiable genealogy and model. To a meaningful degree, global political history is simply the oscillation between universal empires and multi-state systems. In their

This chapter proves the iso-definability of unit vector C when C is a curve using Riemann-Roch. Recall that a pro-definable set is called iso-definable if it is isomorphic, as a pro-definable set, to a definable set. If C is an algebraic curve defined over a valued field F, then unit vector C is an iso-definable set. The topology on unit vector C is definably generated, that is, generated by a definable family of (iso)-definable subsets. In other words, there is a definable family giving a pre-basis of the topology. The chapter explains how definable types on C correspond to germs of paths on

Roman political leaders used distance from Rome as a key political tool to assert pre-eminence. Through the case studies of Caesar’s hegemony, Augustus’s autocracy, and Tiberius’s reign, this book examines how these figures’ experiences and manipulations of absence established a multipolar focus of political life centred less on the city of Rome, and more on the idea of a single leader. The Roman expansion over Italy and the Mediterranean put the political system under considerable stress, and eventually resulted in a dispersal of leadership and a decentralization of power.

The welding process is currently carried out manually and requires a great deal of experience on the part of the welder. In this process, one or more branch member pipes are welded to a base pipe, which vary in their diameters and alignment to each other. This results in a small batch size for which no standard automation solution can be considered. The approach of a pre-defined offline path-planning is no
