Fitting Smooth Paths to Speherical Data

Applied Statistics, 1987
Given a set of data points on the sphere at known times, one often wishes to fit a smooth path to the data. In this paper we propose a unified approach to deal with such problems. Our method can be described as ''unwrapping'' the data onto the plane, where standard curve fitting techniques can then be applied.

Smooth Local Path Planning for Autonomous Vehicles

Proceedings, 1989 International Conference on Robotics and Automation, 1990
Two cost functions of paths for smoothness are defined: path curvature and the derivative of path curvature. Through these definitions, two classes of simple paths are obtained, namely the set of circular arcs and the set of cubic spirals. A cubic spiral is a curve whose tangent direction is described by a cubic function of path distance s.

Smooth Path Algorithm Based on A* in Games

2011
Pathfinding is a core component of many games especially real-time strategy games. The paper proposed a smooth path generation strategy based on the A * algorithm. Firstly, adopted an admissible heuristics function, and a key-point optimization is applied to make the path to be connected by a series of key points.

Smoothing the path of advanced therapies

Nature Italy, 2021
The pandemic has shown how the path from the lab to the clinic can be shortened. These lessons must be applied to innovations such as stem cells and gene therapy.

Mobile robot path planning for fine‐grained and smooth path spcification

Journal of Robotic Systems, 1995
AbstractThis article introduces and draws a comparison on B‐splines and clothoids for generating fine‐grained, smooth path specifications as applied to mobile robot path planning. At one level, a sequence of objective points that the robot must attain to avoid obstacles and to progress toward its goal are supplied by a coarse path planner.

Path smoothing extension for various robot path planners

2016 16th International Conference on Control, Automation and Systems (ICCAS), 2016
Many path planning algorithms have previously been proposed for mobile robots to navigate from a start to a goal location in a given map. These planners generate a path which keeps a safe distance from the obstacles in the map. However, most of the global path planners generate a path with sharp and angular turns which is not desired for robot motion ...

The Intragastric Balloon – Smoothing the Path to Bariatric Surgery

Obesity Surgery, 2006
Intragastric balloon placement in association with diet for weight reduction is steadily gaining popularity. However, long-term follow-up studies on the effect of this method in maintaining weight loss are lacking. This study evaluated the long-term outcome following balloon removal in morbidly obese patients who had selected this method for weight ...

Smooth path planning for autonomous parking system

2017 IEEE Intelligent Vehicles Symposium (IV), 2017
In this paper, we present a path planning algorithm for autonomous parking system. We focus on the kinematics of the car-like vehicle and improve the conventional geometric parking algorithm by proposing a new curve element named linearly steering spiral. A path planning algorithm based on smooth path searching and optimizing are presented. This method

Smoothing the path to the theatre.

Health estate, 2010
How operating theatre design has changed, and the considerable differences in approach taken in the UK, mainland Europe, and North America in the past 5-10 years to enhancing the design of both the theatre itself, and the associated waiting, preparation and recovery facilities, were the subject of a fascinating presentation by Keith Millay, director ...
