"Originally published in 1986, this valuable reference provides a detailed treatment of limit theorems and inequalities for empirical processes of real-valued random variables. It also includes applications of the theory to censored data, spacings, rank statistics, quantiles, and many functionals of empirical processes, including a treatment of bootstrap methods, and a summary of inequalities that are useful for proving limit theorems. At the end of the Errata section, the authors have supplied references to solutions for 11 of the 19 Open Questions provided in the book's original edition."

"This book develops systematically and rigorously, yet in an expository and lively manner, the evolution of general random processes and their large time properties such as transience, recurrence, and convergence to steady states. The emphasis is on the most important classes of these processes from the viewpoint of theory as well as applications, namely, Markov processes."

"The Aluminum 7075 (Al 7075) alloy is a precipitation hardening material instead of a strain hardening material. These mechanical properties are of a particular microstructure obtained by thermo-mechanical treatments. Among other things, this is a complicated microstructure which is responsible for the mechanical performance. The evolution of the mechanical properties of aluminum alloys is dependent on aging time parameters after heat treatment. In this study, the material has undergone a tempering heat treatment followed by a series of tensile tests. The experimental data (tensile curves in three directions during maturation time) is used to describe the evolution of the mechanical characteristics in terms of loading directions and maturation time, denoted respectively as: Ψ and t. The tensile curves are the source of data to begin the problem of identifying the behavior law of studied material using Barlat?s model and Hollomon?s isotropic hardening law. Thus, from the identified parameters (anisotropy coefficients and hardening coefficients), the evolution of the Lankford coefficient, deformation rate and load surfaces during the maturation time for three load directions (0°: rolling direction, 45° and 90°) are described. This study allows optimizing the response of the aluminum alloy to plastic strains, resulting from forming processes measured against the best time during maturation and the best load direction."

"Dalam beroperasinya suatu kapal dibutuhkan sistem yang terfokus mengatur tentang perawatan dan pemeliharaan pada bagian-bagian utama pada kapal tersebut. Sistem pemeliharan dan perawatan ini diterapkan untuk menghindari terjadinya masalah yang nantinya akan menghambat keoptimalan kinerja kapal tersebut. Sistem pemeliharaan kapal yang dilakukan untuk bagian-bagian kapal ini harus di susun secara terencana dan berkala sehingga mampu meningkatkan juga produktivitas kapal serta memperpanjang usia pakai kapal terbut. Dalam penyusunan sistem pemeliharaan kapal atau bisa disebut Plan Maintenance System ini telah diatur dalam ISM Code dan penyusunan sistem pemeliharaan ini sangat diperlukan pada suatu kapal. Dalam hal ini komponen-komponen yang terdapat pada lambung kapal patroli berbahan paduan aluminium yang akan dijadikan sebagai objek penelitian untuk penyusunan sistem pemeliharaan tersebut.

In the operation of the ship a focused system is needed to regulate the treatment and maintenance of the main part of the ship. This treatment and maintenance system is implemented to avoid problems that will obstruct the optimal performance of the ship. The ship maintenance system carried out for these ship parts have to be structured in a planned and periodic, so as to increase the productivity of the ship and extend the age of the ship. In preparing the ship maintenance system or it can be called the Plan Maintenance System, it has been regulated in the ISM Code and the preparation of this maintenance system is indispensable for a ship. In this case the components on the hull of the patrol boat made of aluminum alloy will be used as research objects for the preparation of the maintenance system."

"Because lithium is the least dense elemental metal, materials scientists and engineers have been working for decades to develop a commercially viable aluminum-lithium (Al-Li) alloy that would be even lighter and stiffer than other aluminum alloys. The first two generations of Al-Li alloys tended to suffer from several problems, including poor ductility and fracture toughness; unreliable properties, fatigue and fracture resistance; and unreliable corrosion resistance.
Now, new third generation Al-Li alloys with significantly reduced lithium content and other improvements are promising a revival for Al-Li applications in modern aircraft and aerospace vehicles. Over the last few years, these newer Al-Li alloys have attracted increasing global interest for widespread applications in the aerospace industry largely because of soaring fuel costs and the development of a new generation of civil and military aircraft. This contributed book, featuring many of the top researchers in the field, is the first up-to-date international reference for Al-Li material research, alloy development, structural design and aerospace systems engineering."
