Taking images of individual atoms in color: Researchers at Cornell University are using a new kind of scanning transmission electron microscope STEM to take pictures of individual atoms in color for the first time. It seems odd, but 'the current generation of electron microscopes can be thought of as expensive black and white cameras where different atoms...; Tags: Microscope, Atom, Researcher, Electron, Cornell University, Roland Piquepaille; Blog posts 2008-02-22
Semi-Oblivious Routing: Lower Bounds: This paper initiates the study of semi-oblivious routing; a relaxation of oblivious routing which is first introduced by Racke and led to many subsequent improvements and applications. In semi-oblivious routing like oblivious routing, the algorithm should select only a polynomial number of paths between the source and the sink of...; Tags: Cornell University, Sink, Engineering, Semiconductors, Hardware; White papers 2008-01-01
New ways to reduce computer-related injuries: According to some studies, computing-related injuries, such as carpal tunnel syndromes or back injuries, affect about one-third of computer users. A Cornell University researcher decided to find some ways to help us. So he studied new products able to prevent repetitive motion injuries, including a chair that undulates, a mouse...; Tags: Mouse, Chair, Cornell University, Computer, Mice, Productivity, Hardware, Peripherals, Roland Piquepaille; Blog posts 2007-12-22
Engineering a new curriculum: Engineering a new curriculumSome smaller schools are way ahead hereI teach engineering at two schools in CT. One University of New Haven has a core required course for non-technology students to give them an appreciation and understanding as well as the necessary vocabulary of the role that engineering and...; Tags: Sastry, Cornell University, Cornell, curriculum, new curriculum, social science, democracy, Siemens AG; Discussion threads 2007-09-10
Nanotechnology on the catwalk: This event didnt take place in Paris or Milano, but at Cornell University during their Cornell Design League fashion show on April 21. Its now official: "nanotechnology has entered the fashion world." Fashion designers and fiber scientists have unified their efforts at Cornell to show a two-toned gold dress and...; Tags: Nanotechnology, Leisure, Engineering &, Innovation; Blog posts 2007-05-03

Lighting the nanoworld with nanolamps: An interdisciplinary team of researchers at Cornell University CU has built nanolamps. These extremely small light bulbs are made of light-emitting nanofibers about the size of a virus or the tiniest of bacteria. Using a technique called electrospinning, the researchers spun the fibers from a metallic element, the ruthenium, and...; Tags: Engineering &, Innovation, Science &, Nature, Nanotechnology; Blog posts 2007-04-14
Optimizing Power Consumption in Large Scale Storage Systems: Data centers are the backend for a large number of services that are taken for granted today. A significant fraction of the total cost of ownership of these large-scale storage systems is the cost of keeping hundreds of thousands of disks spinning. This paper presents a simple idea that allows...; Tags: Power Consumption, Cornell University, Storage System, Data Centers, Storage, Storage Management, Hardware, Data Management; White papers 2007-04-10
The Price of Stability for Network Design With Fair Cost Allocation: Network design is a fundamental problem for which it is important to understand the effects of strategic behavior. Given a collection of self-interested agents who want to form a network connecting certain endpoints, the set of stable solutions - the Nash equilibria - may look quite different from the centrally...; Tags: Stability, Network, Allocation, Cornell University, Network Design, Networking, Network Administration; White papers 2007-01-01

Cornell researchers develop projector in your pocket: Coming soon to a cellphone near you ... the latest Hollywood blockbuster on HDTV. MIT Technology Review reports that researchers at Cornell University have developed a laser technology that could lead to the ability to project high-definition television images from devices the size of cell phones. The new technology...; Tags: Cornell University, mirror, MEMS; Blog posts 2006-09-06
SENSTRAC: Scalable Querying of SENSor Networks From Mobile Platforms Using TRACking-Style Queries: Future applications running on mobile platforms will sometimes need to query sensors and track sensor data over time. This paper uses the publish-subscribe paradigm as a natural solution to querying sensors from mobile platforms, and proposes a scalable approach to implement publish-subscribe, driven by the querying application. The approach is...; Tags: Mobile, Network, Sensor, Cornell University, Advertising & Promotion, Marketing; White papers 2006-08-10
Nicer hair for computer-generated blondes: Reproducing hair in computer graphics has always been a challenge, but it has certainly been more difficult for blondes. Now researchers at Cornell University have developed a better method for rendering blond hair. Their new algorithm, which starts by tracing rays from the light source into the hair, is much...; Tags: hair; Blog posts 2006-07-24
Scaling IP Routing With the Core Router-Integrated Overlay: IP routing scalability is based on hierarchical routing, which requires that the IP address hierarchy be aligned with the physical topology. Both site multi-homing and switching ISPs without renumbering break this alignment, resulting in large routing tables. This paper presents CRIO: a new approach to IP scalability for both global...; Tags: Router, Topology, Scalability, IP, Cornell University, Internet Service Providers (ISPs), Network Technology, Routers & Switches, Networking, Internet; White papers 2006-07-18
A signature of the big bang: Today, we'll look at the past, a very old one -- 13.7 billion years to be precise. According to a Cornell University news release, some new satellite data has revealed the beginnings of the universe. This data, based on measurements of the cosmic microwave background radiation CMB, confirms the theory...; Tags: big bang, Cornell University, bang; Blog posts 2006-03-31
On the Scalability of Cooperative Time Synchronization in Pulse-Connected Networks: The problem of time synchronization in dense wireless networks is considered. Well established synchronization techniques suffer from an inherent scalability problem in that synchronization errors grow with an increasing number of hops across the network. In this work, a model for communication in wireless networks is first developed, and then...; Tags: Network, Scalability, Cornell University, Networking, Wi-Fi, Wireless; White papers 2006-02-12
Termite: A Swarm Intelligent Routing Algorithm for Mobile Wireless Ad-Hoc Networks: A biologically inspired algorithm named Termite is presented. Termite directly addresses the problem of routing in the presence of a dynamic network topology. In the Termite algorithm, network status information is embedded in the network through the passage of packets. Probabilistic routing decisions are based on this information such that...; Tags: Algorithm, Mobile, Network, Cornell University, Wireless, Termite, Engineering, Networking; White papers 2006-01-15
The Power of Indirection: Achieving Multicast Scalability by Mapping Groups to Regional Underlays: Reliable multicast is a powerful primitive, useful for data replication, event notification (publish-subscribe), fault-tolerance and other purposes. Yet many of the most interesting applications give rise to huge numbers of heavily overlapping groups, some of which may be large. Existing multicast systems scale poorly in one or both respects. This...; Tags: Group, Scalability, Cornell University, Performance Management, Human Resources, Workforce Management; White papers 2005-11-25
Certified In-Lined Reference Monitoring on .NET: Mobile is an extension of the .NET Common Intermediate Language that supports certified In-Lined Reference Monitoring. Mobile programs have the useful property that if they are well-typed with respect to a declared security policy, then they are guaranteed not to violate that security policy when executed. Thus, when an In-Lined...; Tags: Microsoft .NET, Mobile, Security Policy, Monitoring, Cornell University, Advertising & Promotion, Security, Marketing; White papers 2005-11-11
