Mobicon: A Mobile Context-Monitoring Platform
User context is defined by data generated through everyday physical activity in sensor-rich, resource-limited mobile environments.
The Grand Challenge of Computer Go: Monte Carlo Tree Search and Extensions
The ancient oriental game of Go has long been considered a grand challenge for artificial intelligence. However, computer Go programs based on Monte-Carlo tree search now play at human-master levels and are beginning to challenge top professional players.
Technical Perspective: The Benefits of Capability-Based Protection
Affordable personal computing hardware and the usable GUI-based PC operating systems made the vision of "a computer on every desktop and in every home" a reality. Thanks to the Internet, personal computers did not remain personal for very long.
Technical Perspective: A New Way to Search Game Trees
Researchers in artificial intelligence know that computers still lag far behind human levels of play in many games of strategy. One such contest of wits is Go, which remains a stronghold of human superiority. That may be about to change.
A Taste of Capsicum: Practical Capabilities For Unix
Capsicum is a lightweight operating system capability and sandbox framework planned for inclusion in FreeBSD 9. Capsicum extends, rather than replaces, UNIX APIs, providing new kernel primitives and a userspace sandbox API. These tools support decomposition of monolithic UNIX applications into compartmentalized logical applications.
The Next Generation of GPS Navigation Systems
A live-view GPS navigation system ensures that a user's cognitive map is consistent with the navigation map.
Text-Mining the Voice of the People
Statistical techniques help public leaders turn text in unstructured citizen feedback into responsive e-democracy.
Software as a Service For Data Scientists
Globus Online manages fire-and-forget file transfers for big-data, high-performance scientific collaborations.
Avoid premature commitment, seek design alternatives, and automatically generate performance-optimized software.
Progress and Challenges in Intelligent Vehicle Area Networks
Vehicle area networks form the backbone of future intelligent transportation systems.
Technical Perspective: Modeling High-Dimensional Data
Data in high dimension is difficult to visualize and understand. This has always been the case and is even more apparent now with the availability of large high-dimensional datasets and the need to make sense of them.
Automated synthesis of program fragments from specifications can make programs easier to write and easier to reason about. To integrate synthesis into programming languages, software synthesis algorithms should behave in a predictable way.
The Gaussian mixture model is one of the oldest and most widely used statistical models. Our work focuses on the case where the mixture consists of a small but unknown number of Gaussian "components" that may overlap
Technical Perspective: Compiling What to How
The following paper by Viktor Kuncak et al. integrates declarative programming into a general-purpose language, allowing one to escape the host language when a subproblem can be solved declaratively.
Looking past the systems people use, they target the people using the systems.
Flexible Experimentation in Wireless Sensor Networks
Virtual testbeds model them by seamlessly integrating physical, simulated, and emulated sensor nodes and radios in real time.
Long-Term Confidentiality of PKI
How to guarantee files encrypted and transmitted today stay confidential for years to come.
(Computer) Vision Without Sight
Computer vision holds the key for the blind or visually impaired to explore the visual world.
Technical Perspective: Content-Centric Networking
Much has changed in the 50 years since the invention of packet switching and the early network designs and deployments that would evolve into today's Internet. The designs that began with Cerf and Kahn's 1974 landmark paper have proven durable — a tribute to their prescience and wisdom.
Technical Perspective: Where Do People Draw Lines?
Computer graphics once focused exclusively on realism. The field eventually broadened to include other pictorial styles. The breadth of situations in which line drawings are used makes it important to develop algorithms to generate them either automatically or in a user-assisted manner.
This paper presents the results of a study in which artists made line drawings intended to convey specific 3D shapes.
Current network use is dominated by content distribution and retrieval yet current networking protocols are designed for conversations between hosts. We present Content-Centric Networking which uses content chunks as a primitive — decoupling location from identity, security and access, and retrieving chunks of content by name.
Shape the Future of Computing
ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.
Get InvolvedCommunications of the ACM (CACM) is now a fully Open Access publication.
By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
