This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The accumulation of space debris is increasing at a tremendous rate. More than 25,000 objects of at least 10 cm in diameter orbit the Earth. These objects pose significant danger to other potential spacecraft. Creating methods to stop this increasing process are important for the future for space exploration. This research was solidified by examining the use of solar sail technology as a viable option for mitigating the problem of space debris. Considering only two-dimensional motion, the Gauss Variational Equations (GVEs) were used along with the fundamental solar sail force equation to find a fixed optimal angle for the solar sail to minimize the time to deorbit a space debris in Low Earth Orbit (LEO). Other effects such as gravity from the Moon and Sun were ignored along with low-density drag. Further research was conducted, using the particle swarm optimization (PSO) technique along with the GVEs to find the optimal time-varying angle for the solar sail to minimize the time to deorbit space debris. Both problems are solved by using the computer program MATLAB. Future work will delve into refining the PSO algorithm as applied to this problem in order to obtain improved solutions.

Book excerpt: When the first sputnik was launched and the space era began, few gave thought to the possible negative impact of putting satellites into orbit. In fact, man's space activity has led to the formation of a new media named "space debris," i.e. man-made objects and their fragments launched into space, currently inactive and no longer serving any useful

Download or read book Particle Swarm Optimization written by Said M. Mikki and published by Morgan & Claypool Publishers. This book was released on 2008 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work aims to provide new introduction to the particle swarm optimization methods using a formal analogy with physical systems. By postulating that the swarm motion behaves similar to both classical and quantum particles, we establish a direct connection between what are usually assumed to be separate fields of study, optimization and physics. Within this framework, it becomes quite natural to derive the recently introduced quantum PSO algorithm from the Hamiltonian or the Lagrangian of the dynamical system. The physical theory of the PSO is used to suggest some improvements in the algorithm itself, like temperature acceleration techniques and the periodic boundary condition. At the end, we provide a panorama of applications demonstrating the power of the PSO, classical and quantum, in handling difficult engineering problems. The goal of this work is to provide a general multi-disciplinary view on various topics in physics, mathematics, and engineering by illustrating their interdependence within the unified framework of the swarm dynamics.

Download or read book New Solutions for the Space Debris Problem written by Joseph N. Pelton and published by Springer. This book was released on 2015-05-06 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing a pressing issue in space policy, Pelton explores the new forms of technology that are being developed to actively remove the defunct space objects from orbit and analyzes their implications in the existing regime of international space law and public international law. This authoritative review covers the due diligence guidelines that nations are using to minimize the generation of new debris, mandates to de-orbit satellites at end of life, and innovative endeavours to remove non-functional satellites, upper stage rockets and other large debris from orbit under new institutional, financial and regulatory guidelines. Commercial space services currently exceed 100 billion USD business per annum, but the alarming proliferation in the population of orbital debris in low, medium and geosynchronous satellite orbits poses a serious threat to all kinds of space assets and applications. There is a graver concern that the existing space debris will begin to collide in a cascading manner, generating further debris, which is known as the Kessler Syndrome. Scientific analysis has indicated an urgent need to perform space debris remediation through active removal of debris and on-orbit satellite servicing.

Book excerpt: Space debris has been and still remains a growing threat for the international space community. As a source of pollution, orbiting debris adversely damages the space environment. There is an increased risk of additional debris being generated by colliding with space objects, and such fragments remaining in space permanently. Every space actors, whether State-sponsored, civilians or commercial, are affected by the space debris population. Human lives are endangered: astronauts undertaking extra-vehicular activities or even the paying public enjoying commercial human spaceflights run the risk of colliding with pieces of debris. The continuing growth of debris in heavily used orbital regions, like Low Earth Orbit (LEO) and Geostationary Earth Orbit (GEO), not causes minor or complete abruptions to space operations, but potentially could prevent launches of planned space vehicles; thus, denying future access to, and use of, outer space. Further to stifling space development, the quality of the space environment is degrading, therefore. Preserving and sustaining that environment as a valuable resource for future space users has motivated interested space bodies to consider mechanisms to control the increase of debris. Such international meetings like the 5th European Conference on Space Debris and the US House of Representatives Committee on Science and Technology's Subcommittee on Space and Aeronautics on 'Keeping the Space Environment Safe for Civil and Commercial Space Users' have arrived to the same conclusion: better international agreed space debris mitigation methods to reduce the probability of additional debris must be created as well as remediation mechanisms being imposed. This Paper shall explore the different meanings and sources of 'space debris'. The population of orbital debris, also, is quantified, and three galvanising events are identified and commented as exacerbating its growth since 2007. This Paper then shall examine the effectiveness of space debris mitigation practices, which were adopted by the international space community, to tackle the rising population of orbiting debris. These measures are not binding under international space law: compliance is voluntary. The Space Debris Mitigation Guidelines are preventative practices designed to control the increase of space congestion in popular orbital regions like LEO and GEO to preserve their commercial and scientific value as well as use of, and access to, by future space users. It shall be demonstrated that in the absence of legal liability and sanctioning being imposed on space operators the mitigation practices can be ignored.
Download or read book Particle Swarm Optimisation written by Jun Sun and published by CRC Press. This book was released on 2011-12-19 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the particle swarm optimisation (PSO) algorithm requires relatively few parameters and is computationally simple and easy to implement, it is not a globally convergent algorithm. In Particle Swarm Optimisation: Classical and Quantum Perspectives, the authors introduce their concept of quantum-behaved particles inspired by quantum mechanics, which leads to the quantum-behaved particle swarm optimisation (QPSO) algorithm. This globally convergent algorithm has fewer parameters, a faster convergence rate, and stronger searchability for complex problems. The book presents the concepts of optimisation problems as well as random search methods for optimisation before discussing the principles of the PSO algorithm. Examples illustrate how the PSO algorithm solves optimisation problems. The authors also analyse the reasons behind the shortcomings of the PSO algorithm. Moving on to the QPSO algorithm, the authors give a thorough overview of the literature on QPSO, describe the fundamental model for the QPSO algorithm, and explore applications of the algorithm to solve typical optimisation problems. They also discuss some advanced theoretical topics, including the behaviour of individual particles, global convergence, computational complexity, convergence rate, and parameter selection. The text closes with coverage of several real-world applications, including inverse problems, optimal design of digital filters, economic dispatch problems, biological multiple sequence alignment, and image processing. MATLAB®, Fortran, and C++ source codes for the main algorithms are provided on an accompanying CD-ROM. Helping you numerically solve optimisation problems, this book focuses on the fundamental principles and applications of PSO and QPSO algorithms. It not only explains how to use the algorithms, but also covers advanced topics that establish the groundwork for understanding state-of-the-art research in the field.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book devoted entirely to Particle Swarm Optimization (PSO), which is a non-specific algorithm, similar to evolutionary algorithms, such as taboo search and ant colonies. Since its original development in 1995, PSO has mainly been applied to continuous-discrete heterogeneous strongly non-linear numerical optimization and it is thus used almost everywhere in the world. Its convergence rate also makes it a preferred tool in dynamic optimization.
