Recipe For Efficiency: Principles of Power-Aware Computing
Prior work on power management reflects recurring themes that can be leveraged to make future systems more energy efficient.
Andrew S. Tanenbaum talks about MINIX, microkernels, and electronic voting systems.
CHOC’LATE: A Framework For Specification-Based Testing
In spite of its importance in software reliability, testing is labor intensive and expensive. It has been found that software testing without a good strategy may not be more effective than testing the system with random data.
Swarms of Helicopter Robots Could Create Huge 3-D Displays
The Flyfire project at MIT's SENSEable City Laboratory is creating tiny LED-equipped helicopters that will move in concert to create dramatic, free-form displays.
Researchers are focusing on the so-called "removal chain" in an attempt to save landfill space, improve recycling rates, and trim the flow of toxic materials into the environment.
Technical Perspective: Seeing the Trees, the Forest, and Much More
Bristling with cameras, microphones, and other sensors, today's portable phones are nevertheless essentially deaf and blind. How shall we go about building machines that can see, hear, smell, touch?
Using the Forest to See the Trees: Exploiting Context For Visual Object Detection and Localization
Recognizing objects in images is an active area of research in computer vision. However, most of the algorithms for detecting objects perform an exhaustive search across all locations and scales in the image comparing local image regions with an object model. That approach ignores the semantic structure of scenes and tries to solve the recognition problem by brute force.
Almost 90% of what we learn comes from reading, estimates say, and the path that online information takes to your brain is less direct than most. The Communications Web site gets most of its readers from someplace else: 56.6% from referring sites, like Slashdot or Reddit, and 14.3% from search engines. Google alone sends 13.6%.
Toward Energy-Efficient Computing
What will it take to make server-side computing more energy efficient?
Virtual Computing Initiative at a Small Public University
Student participation and resulting expertise is as valuable as having the high-performance resource itself.
Making Decisions Based on the Preferences of Multiple Agents
Computer scientists have made great strides in how decision-making mechanisms are used.
Recent Progress in Quantum Algorithms
What quantum algorithms outperform classical computation and how do they do it?
Power-manageable hardware can help save energy, but what can software developers do to address the problem?
Managing Contention For Shared Resources on Multicore Processors
Contention for caches, memory controllers, and interconnects can be eased by contention-aware scheduling algorithms.
Software Model Checking Takes Off
A translator framework enables the use of model checking in complex avionics systems and other industrial settings.
Informatics Creativity: A Role For Abductive Reasoning?
Despite the fact that creative problem solving is desirable at all levels, it is constantly in short supply. Part of the problem may be that while some technology trainers advocate the search for creative solutions, the learning side of the equation is little changed by a "be creative" lecture component.
Can Automated Agents Proficiently Negotiate With Humans?
Exciting research in the design of automated negotiators is making great progress.
New Search Challenges and Opportunities
If search engines can extract more meaning from text and better understand what people are looking for, the Web's resources could be accessed more effectively.
Buildings collapse. Wind and rain beat them, temperatures cycle from freezing to blistering, and random strikes of lightning threaten sudden obliteration. Even more potent are the human challenges: war, fire, and deliberate destruction. But digital representations can survive such dangers, capturing structures forevermore.
Automated Translation of Indian Languages
India faces a daunting task trying to manually translate among 22 official languages, but assistance, in the form of advanced technology enabled by a lot of hard work, is on the way.
Structural Characterizations of Schema-Mapping Languages
Information integration is a key challenge faced by all major organizations, business and governmental ones alike. Two research facets of this challenge that have received considerable attention in recent years are data exchange and data integration.
Random Selection from a Stream of Events
Consider a stream of events received during a limited period of time, such as applications on the Internet. One event needs to be randomly selected as a "winner." Due to physical limitations, the list of all events cannot be stored.
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.
