This book constitutes the refereed proceedings of the 6th International Workshop on Multiple Access Communications, MACOM 2013, held in Vilnius, Lithuania, in December 2013. The 16 full papers presented were carefully reviewed and selected from various submissions. They describe the latest advancements in the field of multiple access communications with an emphasis on OFDM techniques, channel coding, spectrum management, medium access control protocols and different aspects of wireless access networks.

This book constitutes the refereed proceedings of the 19th International Conference on Analytical and Stochastic Modelling Techniques and Applications, ASMTA 2012, held in Grenoble, France, in June 2012. The 20 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on queueing systems; networking applications; Markov chains; stochastic modelling.

It is our great pleasure to present the proceedings of the 16th International ConferenceonAnalyticalandStochasticModellingTechniquesandApplications (ASMTA 2009) that took place in Madrid. The conference has become an established annual event in the agenda of the experts of analytical modelling and performance evaluation in Europe and internationally. This year the proceedings continued to be published as part of Springer's prestigiousLecture Notes in Computer Science (LNCS) series. This is another sign of the growing con?dence in the quality standards and procedures followed in the reviewing process and the program compilation. Following the traditions of the conference, ASMTA 2009, was honored to have a distinguished keynote speaker in the person of Kishor Trivedi. Professor Trivedi holds the Hudson Chair in the Department of Electrical and Computer EngineeringatDukeUniversity, Durham, NC, USA. HeistheDuke-SiteDirector of an NSF Industry-University Cooperative Research Center between NC State University and Duke University for carrying out applied research in computing and communications. He has been on the Duke faculty since 1975. He is the author of a well-known text entitled Probability and Statistics with Reliability, Queuing and Computer Science Applications, published by Prentice-Hall, the secondeditionofwhichhasjustappeared. Hehasalsopublishedtwootherbooks entitled Performance and Reliability Analysis of Computer Systems, published by Kluwer Academic Publishers, and Queueing Networks and Markov Chains, by John Wiley. He is also known for his work on the modelling and analysis of software aging and rejuvenation. The conference maintained the tradition of high-quality programs with an acceptance rate of about 40%.

This book constitutes the refereed proceedings of the 13th European Workshop on Computer Performance Engineering, EPEW 2016, held in Chios, Greece, in October 2016. The 14 papers presented together with 2 invited talks in this volume were carefully reviewed and selected from 25 submissions. The papers presented at the workshop reflect the diversity of modern performance engineering, with topics ranging from the analysis of queueing networks and stochastic processes, to performance analysis of computer systems and networks, and even modeling of human behavior.
