1 This book provides an overview of Moving Target Defense (MTD) and the importance of developing novel MTD schemes to protect distributed systems It presents MTD-based research efforts to protect cloud data centers, along with network and security risk-aware approaches to place Virtual Machines (VM) in cloud data centers These approaches include MTD-based network diversity models that enable an evaluation of the robustness of cloud data centers against potential zero-day attacks Since these models can be used as a security metric the authors include different network configurations and policies, consider the similarity and dissimilarity of network resources, and account for minimum impact to maximum impact attacks Also offered is a framework for determining the cost of MTD-based VM migration on cloud data centers
Designed for researchers and practitioners, Moving Target Defense for Distributed Systems enables readers to understand the potential of MTD capabilities It enables defenders to change system or network behaviors, policies, and configurations automatically to keep potential attack surfaces protected Advanced level students in computer science, especially those interested in networks and security, will benefit from this book

2 This book contributes to making urban rail transport fast, punctual and energy-efficient -significant factors in the importance of public transportation systems to economic, environmental and social requirements at both municipal and national levels It proposes new methods for shortening passenger travel times and for reducing energy consumption, addressing two major topics: (1) train trajectory planning: the authors derive a nonlinear model for the operation of trains and present several approaches for calculating optimal and energy-efficient trajectories within a given schedule; and (2) train scheduling: the authors develop a train scheduling model for urban rail systems and optimization approaches with which to balance total passenger travel time with energy efficiency and other costs to the operator

Mixed-integer linear programming and pseudospectral methods are among the new methods proposed for single- and multi-train systems for the solution of the nonlinear trajectory planning problem which involves constraints such as varying speed restrictions and maximum traction/braking force Signaling systems and their effects are also accounted for in the trajectory planning model

Origin-destination passenger demand is included in the model formulation for train scheduling Iterative convex programming and efficient bi-level approaches are utilized in the solution of the train-scheduling problem In addition, the splitting rates and route choices of passengers are also optimized from the system point of view

The problems and solutions described in Optimal Trajectory Planning and Train Scheduling for Urban Rail Transit Systems will interest researchers studying public transport systems and logistics whether from an academic or practitioner background as well as providing a real application for anybody studying optimization theory and predictive control

3 This brief examines recent developments in the Heterogeneous Vehicular NETworks (HETVNETs), integrating cellular networks with Dedicated Short-Range Communication (DSRC) for meeting the communications requirements of the Intelligent Transport System (ITS)services Along with a review of recent literature, a unified framework of the HetVNET is presented The brief focuses on introducing efficient MAC mechanisms for vehicular communications, including channel access protocols, broadcast/multicast protocols, the location-based channel congestion control scheme and the content-based resource allocation scheme The cooperative communication between vehicles is discussed

This brief concludes with a discussion on future research directions, and provides the readers with useful insights into the future designs in the HetVNETs, to motivate new ideas for performance improvements in vehicular networks

4 This book introduces a new intuitive design methodology for the optimal design path for next-generation software defined radio front-ends (SDRXs) The methodology described empowers designers to “attack” the multi-standard environment in a parallel way rather than serially, providing a critical tool for any design methodology targeting 5G circuits and systems Throughout the book the SDRX design follows the key wireless standards of the moment (i e , GSM, WCDMA, LTE, Bluetooth, WLAN), since a receiver compatible with these standards is the most likely candidate for the first design iteration in a 5G deployment The author explains the fundamental choice the designer has to make regarding the optimal channel selection: how much of the blockers/interferers will be filtered in the analog domain and how much will remain to be filtered in the digital domain The system-level analysis the author describes entails the direct sampling architecture is treated as a particular case of mixer-based direct conversion architecture This allows readers give a power consumption budget to determine how much filtering is required on the receive path, by considering the ADC performance characteristics and the corresponding blocker diagram

5 The book provides a complete overview of the SIMATIC automation system and the TIA Portal with the engineering tool STEP 7 “Automating with SIMATIC” addresses all those who
– want to get an overview of the components of the system and their features,
– wish to familiarize themselves with the topic of programmable logic controllers, or
– intend to acquire basic knowledge about configuration, programming and interaction of the SIMATIC components

At first, the book introduces the hardware of SIMATIC S7-1200, S7-300, S7-400 and S7-1500, including the ET 200 peripheral modules This is followed by describing the work with STEP 7 in the programming languages LAD, FBD, STL, SCL and S7-Graph, and offline testing with S7-PLCSIM The next section describes the structure of the user program, which is followed by the illustration of the data communication between the controllers of the automation system as well as with the peripheral devices by use of the bus systems Profinet and Profibus The book closes with a survey of the devices for operator control and process monitoring and their configuration software
