The value in name patients

In all the coverage of Sen. Edward Kennedy's brain tumor, one fact has gone little remarked. The surgery is taking place at Duke. Not in Massachusetts. In North Carolina. The surgeon is Dr. Allan H. Friedman (right, from Duke University Medical Center). He was...

Scalability and Accuracy in a Large-Scale Network Emulator

This paper presents ModelNet, a scalable Internet emulation environment that enables researchers to deploy unmodified software prototypes in a configurable Internet-like environment and subject them to faults and varying network conditions. Edge nodes running user-specified OS and application software are configured to route their packets through a set of ModelNet...

Using Random Subsets to Build Scalable Network Services

This paper argues that a broad range of large-scale network services would benefit from a scalable mechanism for delivering state about a random subset of global participants. Key to this approach is ensuring that membership in the subset changes periodically and with uniform representation over all participants. Random subsets could...

Balancing Site Goals and Service Goals in Datacenter Management

A shift is witnessed from large mainframe computing to commodity, off-the-shelf clusters of servers. The cluster paradigm allows organizations to acquire resources at a fine granularity, scaling the cluster to provide the resources necessary for increasingly-powerful simulations, multimedia rendering, and web farms. As yesterday's clusters grow into today's data centers,...

Printing with enzymes

Researchers at Duke University have developed a new printing technique using catalysts to create microdevices such as labs-on-a-chip. Their inkless printing technique uses enzymes from E. coli bacteria and has an accuracy of less than 2 nanometers. While they're are now using enzymes to stamp nanopatterns without ink, the research...

CAD-CAM for nanotechnology manufacturing

A team of U.S. researchers has used a computer aided design and manufacturing (CAD-CAM) process to guide an atomic force microscope AFM. According to them, this automated technique is 'paving the way for a nanotechnology's industrial revolution.' And their results look very promising. If they're confirmed -- and adopted by...

Characterizing Intrusion Tolerant Systems Using a State Transition Model

Intrusion detection and response research has so far mostly concentrated on known and well-defined attacks. The authors believe that this narrow focus of attacks accounts for both the successes and limitation of commercial in Intrusion Detection Systems IDS. Intrusion tolerance, on the other hand, is inherently tied to functions and...

Watch your future baby in 3-D

If researchers from Duke University can successfully install an updated version of a new image-viewing software found on clinical ultrasound scanners, it soon could be possible to see developing fetuses in the womb in living 3-D movies. These 3-D ultrasound imaging systems dont need any additional hardware, except special goggles....

TCP Performance Re-Visited

Detailed measurements and analyses for the Linux-2.4 TCP stack on current adapters and processors are presented. The impact of CPU scaling and memory bus loading on TCP performance is also described. As CPU speeds outstrip I/O and memory speeds, many generally accepted notions of TCP performance begin to unravel. In-depth...

Defining Steady-State Service Level Agreeability Using Semi-Markov Process

The ability of the servers to deliver services to the clients according to pre-defined agreements is becoming an important requirement. These pre-defined agreements are sometimes referred to as Service Level Agreements SLA. In most practical cases, these agreements are based on the response times observed by the customer. This service...

A unified theory of animal locomotion

You probably already know that there is a master equation for all life processes based on metabolism. Now, physicists from Duke University have applied the so-called 'constructal theory' to explain how running, flying and swimming modes of locomotion are similar even if they're apparently unrelated. And this single unifying physics...
