SME Strategies: An Assessment of High vs. Low Performers
Little has been known about how and to what extent small-medium sized enterprises (SMEs) are implementing supply chain management (SCM) initiatives and e-business practices. This article presents some preliminary survey results of relationships between environment, firm strategy and performance. It also discusses the comparative characteristics of strategies and practices between high and low performance SMEs.
User-Centric Services Provisioning in Wireless Environments
To date, services provided for mobile users are still hard to build. Two main challenges need to be considered. The first challenge is about the personalized access to services. The second challenge is about handling limited resources of mobile devices.
A European Perspective of VoIP in Market Competition
The debate on the future of VoIP (Voice Over Internet Protocol) is not new. For some time now this technological innovation has been considered one of main drivers for reshaping the telecommunications industry.
Technology Acceptance and ERP Documentation Usability
Enterprise resource planning (ERP) Systems have a reputation for being complex, problematic to implement and difficult for users to learn. The technology puts pressure on organizations to change their processes, leaving users struggling to relearn their jobs and day-to-day tasks even while coping with non-intuitive new software.
CTO Roundtable on Virtualization: Part I
Virtualization technology is hot again, but for the right reasons?
The Many Facets of Natural Computing
Natural computing builds a bridge between computer science and natural sciences.
Knowing the structure of criminal and terrorist networks could provide the technical insight needed to disrupt their activities.
Technical Perspective: Computational Photography on Large Collections of Images
This paper wil strike a familiar chord with anyone who has ever taken a picture. The problem is easy to understand— replacing unwanted parts of a photograph.
Scene Completion Using Millions of Photographs
What can you do with a million images? In this paper, we present a new image completion algorithm powered by a huge database of photographs gathered from the Web.
Daphne Koller discusses probabilistic relational modeling, artificial intelligence, and her new work with biologists.
How do we apply the concept of resource orientation by designing representations to support interactions?
As the line between GPUs and CPUs begins to blur, it's important to understand what makes GPUs tick.
Understanding Evolution in Technology Ecosystems
The current environment of information technology can be a complex place for analysts and firms to navigate, especially when making decisions about new product development, technology investment, and technology planning. Many industry analysts recognize that it is difficult, if not impossible, to accurately predict future technological advances.
RFID in the Supply Chain: Panacea or Pandora's Box?
Today, it is widely believed that the use of radio frequency identification (RFID) technology will enable substantive supply chain transformations. RFID can help reduce counterfeiting, theft, and the bullwhip effect; it can improve on-shelf availability, customer service, inventory management, downstream forecasting, warehouse and back room operations.
Spectral graph theory has proven to be very useful for text search and retrieval and for refining predictive-analysis systems.
The Student Productivity Paradox: Technology Mediated Learning in Schools
With increasing pressure on educational institutions to enhance learning outcomes and effectiveness, many school administrators and school boards are investing heavily in information and communications technologies (ICT). Of the 51 chief state school officers in the U.S., 48 ranked the “use of technology in instruction” as the second most important issue facing public education in […]
Technical Perspective: Transactional Memory in the Operating System
The long tradition of building ever-faster processors is ending, with the computer industry instead putting more processing "cores" on each processor chip. Therefore, to continue to benefit from advances in technology, applications must increasingly be able to perform useful work on multiple cores at the same time.
TxLinux and MetaTM: Transactional Memory and the Operating System
TxLinux is the first operating system to use hardware transactional memory (HTM) as a synchronization primitive, and the first to manage HTM in the scheduler. TxLinux, a modification of Linux, is the first real-scale benchmark for transactional memory.
Expect virtual immortality through enduring, realistic avatars based on published work and archived memory.
Scalable and distributed video coding offers the promise of two-way, real-time video.
Technical Perspective: A Methodology For Evaluating Computer System Performance
Computer science has long had a solid foundation for evaluating the performance of algorithms. The asymptotic complexity of the time required by an algorithm is well defined and usually tractable, allowing for a clear evaluation of whether one algorithm provides a fundamental improvement over another.
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.
