Technical Perspective: A New Spin on an Old Algorithm
A paper by Ballard, Demmel, Holtz, and Schwartz considers a fundamental problem, adopting a new perspective on an old algorithm that has for years occupied a peculiar place in the theory and practice of matrix algorithms.
Technical Perspective: Silicon Stress
Moore's Law has been the mainstay of semiconductor electronics since the invention of the transistor and its application to the integrated circuit. Implicit in this evolution is the assumption that we can print these circuits in an economical manner. This assumption is now in question.
TSV Stress-Aware Full-Chip Mechanical Reliability Analysis and Optimization For 3D IC
Three-dimensional integrated circuit (3D IC) with through-silicon-via (TSV) is believed to offer new levels of efficiency, power, performance, and form-factor advantages over the conventional 2D IC.
A Historical Perspective of Speech Recognition
What do we know now that we did not know 40 years ago?
Retweeting the Fukushima Nuclear Radiation Disaster
The Japanese government tweeted to calm public fear, as the public generally listened to tweets expressing alarm.
Touchless Interaction in Surgery
Touchless interaction with medical images lets surgeons maintain sterility during surgical procedures.
Democratizing Transactional Programming
Control transactions without compromising their simplicity for the sake of expressiveness, application concurrency, or performance.
Legal Aspects of Interface Accessibility in the U.S.
Accessible information technology is not just good design and a clever way to win new users, it is the law.
Big data promises automated actionable knowledge creation and predictive models for use by both humans and computers.
Replicated Data Consistency Explained Through Baseball
A broader class of consistency guarantees can, and perhaps should, be offered to clients that read shared data.
Technical Perspective: The Cleanest Garbage Collection
In quite a tour de force, the authors of the following paper have built a provably correct real-time garbage collector for reconfigurable hardware (field programmable gate arrays).
And Then There Were None: A Stall-Free Real-Time Garbage Collector For Reconfigurable Hardware
We present a garbage collector synthesized directly to hardware, capable of collecting a heap of uniform objects completely concurrently. These heaps are composed entirely of objects of a fixed shape. Thus, the size of the data fields and the location of pointers of each object are fixed.
Computing Technologies For Reflective, Creative Care of People with Dementia
Mobile apps manage data on individual residents to help carers deliver more person-centered care.
Media Tablets For Mobile Learning
Tablets offer hope for improving learning and collaboration but only if truly integrated into learning settings.
The competitive nature of AT, the scarcity of expertise, and the vast profits potential, makes for a secretive community where implementation details are difficult to find.
Adaptation of Audiovisual Contents and Their Delivery Means
Coupling content adaptation with context awareness is a promising approach for improving the user's experience.
Technical Perspective: Centip3De Demonstrates More Than Moore…
Exponentially increasing transistor integration also demands more interconnections, which have started hitting fundamental limits. The Centip3De design demonstrates two concepts to address this challenge: near-threshold computing, and 3D integration.
Centip3De: A Many-Core Prototype Exploring 3D Integration and Near-Threshold Computing
This paper evaluates the use of three-dimensional integration to reduce global interconnect by adding multiple layers of silicon with vertical connections between them using through-silicon vias.
Formal Verification of Phase-Locked Loops Using Reachability Analysis and Continuization
We present a scalable and formal technique to verify locking time and stability for charge-pump phase-locked loops (PLLs).
Trends in Computer Science Research
Keywords in the ACM Digital Library and IEEE Xplore digital library and in NSF grants anticipate future CS research.
Improve online public discourse by connecting opinions across blogs, editorials, and social media.
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.
