Analysis, assessment, and data management are core competencies for operation research analysts. This volume addresses a number of issues and developed methods for improving those skills. It is an outgrowth of a conference held in April 2013 at the Hellenic Military Academy, and brings together a broad variety of mathematical methods and theories with several applications. It discusses directions and pursuits of scientists that pertain to engineering sciences. It is also presents the theoretical background required for algorithms and techniques applied to a large variety of concrete...

This book examines the common metaphor that equates computing and writing, tracing it from the naming of devices ("notebook" computers) through the design of user interfaces (the "desktop") to how we describe the work of programmers ("writing" code). Computing as Writing ponders both the implications and contradictions of the metaphor.

During the past decade, analysis of digital media honed its focus on particular hardware and software platforms. Daniel Punday argues that scholars should, instead, embrace both the power and the fuzziness of the writing metaphor as it relates...

This book constitutes the thoroughly refereed post-conference proceedings of the 13th International Workshop on Digital-Forensics and Watermarking, IWDW 2014, held in Taipei, Taiwan, during October 2014.

The 32 full and 14 poster papers, presented together with 1 keynote speech, were carefully reviewed and selected from 79 submissions. The papers are organized in topical sections on forensics; watermarking; reversible data hiding; visual cryptography; and steganography and steganalysis.

Infrastructure makes worlds. Software coordinates labor. Logistics governs movement. These pillars of contemporary capitalism correspond with the materiality of digital communication systems on a planetary scale. Ned Rossiter theorizes the force of logistical media to discern how subjectivity and labor, economy and society are tied to the logistical imaginary of seamless interoperability. Contingency haunts logistical power. Technologies of capture are prone to infrastructural breakdown, sabotage, and failure. Strategies of evasion, anonymity, and disruption unsettle regimes of calculation...

The ubiquitous nature of mobile and pervasive computing has begun to reshape and complicate our notions of space, time, and identity. In this collection, over thirty internationally recognized contributors reflect on ubiquitous computing s implications for the ways in which we interact with our environments, experience time, and develop identities individually and socially. Interviews with working media artists lend further perspectives on these cultural transformations. Drawing on cultural theory, new media art studies, human-computer interaction theory, and software studies, this...

This work adds a new perspective to the stream of organizational IT security risk management literature, one that sheds light on the importance of IT security risk perceptions. Based on a large-scale empirical study of Cloud providers located in North America, the study reveals that in many cases, the providers' decision makers significantly underestimate their services' IT security risk exposure, which inhibits the implementation of necessary safeguarding measures. The work also demonstrates that even though the prevalence of IT security risk concerns in Cloud adoption is widely...

Why does information technology disappoint or enslave us? Why do so many information systems projects collapse? How can we do better? There are many technical, social, economic and other aspects to consider. How do we ensure we take all these into account as we research ITC or employ them? ICT affects our lives and world more profoundly than ever before. How may we understand it? This book employs philosophy to lay foundations for understanding the complexity of ICT, in five areas:

• The nature of information and computers, and artificial intelligence;

The two-volume set LNCS 9452 and 9453 constitutes the refereed proceedings of the 21st International Conference on the Theory and Applications of Cryptology and Information Security, ASIACRYPT 2015, held in Auckland, New Zealand, in November/December 2015.

The 64 revised full papers and 3 invited talks presented were carefully selected from 251 submissions. They are organized in topical sections on indistinguishability obfuscation; PRFs and hashes; discrete logarithms and number theory; signatures; multiparty computation; public key encryption; ABE and IBE; zero-knowledge; attacks...

The first part of this book covers the key concepts of cryptography on an undergraduate level, from encryption and digital signatures to cryptographic protocols. Essential techniques are demonstrated in protocols for key exchange, user identification, electronic elections and digital cash. In the second part, more advanced topics are addressed, such as the bit security of one-way functions and computationally perfect pseudorandom bit generators. The security of cryptographic schemes is a central topic. Typical examples of provably secure encryption and signature schemes and their security...
