Software
Climate change is likely to be one of the defining global issues of the 21st century. The past decade—the hottest in recorded history—has witnessed countries around the world struggling to deal with drought, heat waves, and extreme weather. The sheer scale of the problem also makes it hard to understand, predict, and solve. Climate science journals regularly publish special issues on specific climate models, typically timed to present results from a major new release of a given model. However, these tend to focus on the new science that the model enables, rather than describing the software and its development. The November/December special issue of Software focuses on the software behind climate change models.
Intelligent Systems
Over the past 30 years, video surveillance systems have been a key part of intelligent transportation systems (ITSs), which use various image sensors to capture visual information about vehicles and pedestrians to provide real-time information about traffic conditions. Specifically, they capture vehicles' visual appearances and support mining more information about them through detection, localization, classification, recognition, behavior analysis, and so on. Video systems also help generate overall vehicle statistics such as estimations of flow rate, average speed, and density.
In "Hierarchical and Modular Surveillance Systems in ITS" in the September/October issue of IS, the authors describe video surveillance system studies aimed at developing and increasing the capacity to obtain various types of traffic information. Based on the analysis of problems in present surveillance systems and their understanding of the current status and future of surveillance systems, the authors propose a new framework for video surveillance systems, the hierarchical and modular surveillance system (HMSS).
Computer Graphics
Researchers have previously studied brain injury in children by assessing linear and angular accelerations, but without taking into account vibratory loads. In "Modeling Neck and Brain Injuries in Infants" in the November/December issue of CG&A, authors Ernesto Ponce, of the Universidad de Tarapacá, and Daniel Ponce, of the Universidad Federal de Santa Catarina, propose an approach that employs a new mathematical head model that includes vibration to analyze how shaken-baby syndrome affects infants. To account for vibrations, the model applies finite-element methods to model the stresses, strains, and displacements in the neck vertebrae and brain.
Computing
Scientific computing increasingly involves massive data; in astronomy, observations and numerical simulations are on the verge of generating petabytes. This innovative data-centric computing requires a new look at computing architectures and strategies. In "Extreme Data-Intensive Scientific Computing" in the November/December issue of CiSE, author Alex Szalay of Johns Hopkins University says that by using Amdahl's law to characterize architectures and workloads, it's possible to use existing commodity parts to build systems that approach an ideal Amdahl machine.
Security & Privacy
A cyberwar exists between malware writers and antimalware researchers. At this war's heart rages a weapons race that originated in the 1980s with the first computer virus. Obfuscation is one of the latest strategies to camouflage the telltale signs of malware, undermine antimalware software, and thwart malware analysis. Malware writers use packers, polymorphic techniques, and metamorphic techniques to evade intrusion detection systems. In "Obfuscation: The Hidden Malware," in the September/October issue of S&P, a team of authors from the Centre for Secure Information Technologies at Queen's University Belfast argues for new antimalware approaches that focus on what malware is doing rather than how it's doing it.
Pervasive Computing
The October-December issue of PvC looks at a range of applications that have the potential to impact our everyday lives. Two reports describe sensor-based systems for energy management and eldercare, while three automotive computing proposals offer solutions for activity promotion, path prediction, and vehicle passing. Other proposals explore eyes-free solutions for the mobile Web, the use of humans as sensors for increased reliability, and a smartphone-based sensor that assists in early stroke diagnosis.
Internet Computing
Advances in wireless networks and mobile devices have motivated an intensive research effort in mobile computing and mobile data services. The goal is to provide users with anywhere, anytime connectivity to the Internet along with access to services that are valuable depending on a user's context. One of the most interesting context factors is user location. In "Semantics in Location-Based Services," IC's September/October guest editors Sergio Ilarri, Arantza lllarramendi, Eduardo Mena, and Amit Sheth introduce several articles on context-aware services.
Micro
"GPUs and the Future of Parallel Computing" in the September/October issue of Micro discusses the capabilities of state-of-the art GPU-based high-throughput computing systems and considers the challenges to scaling single-chip parallel-computing systems, highlighting high-impact areas that the computing research community can address. A team of authors from Nvidia Research describes the firm's Echelon project for developing architectures and programming systems that aim specifically at the energy efficiency and locality challenges facing future systems.
MultiMedia
Techniques that enhance television sports broadcasts use algorithms to track objects such as a ball or puck to create informative, graphical visualizations embedded into the broadcast image. A coalition of researchers from sports broadcasters and Georgia universities investigate recent advances in sports visualizations in "Augmenting Live Broadcast Sports with 3D Tracking Information," in the October-December issue of MultiMedia.
IT Professional
In the basement of the Hoover building in Washington, D.C., FBI employees and contractors are working together to create Sentinel, a case-management software system designed to revolutionize how the FBI gathers, stores, and links its data. Read "The FBI Gets Agile" in the September/October issue of IT Pro to learn how the FBI team used agile methods to transform this time-consuming, expensive, and off-track government IT project into a successful program. The FBI's experience in developing Sentinel provides practical insight into how government agencies and other traditionally nonsoftware-development-focused organizations can exploit agile methodologies.
Annals
The electrical efficiency of computation has doubled roughly every year and a half for more than six decades, a pace of change comparable to that for computer performance and electrical efficiency in the microprocessor era. "Implications of Historical Trends in the Electrical Efficiency of Computing" in the July-September issue of Annals looks at how these efficiency improvements enabled the creation of laptops, smartphones, wireless sensors, and other mobile computing devices, with many more such innovations yet to come. A Web Extra appendix outlines the data and methods used in this study.
