Evaluation of Sampling for Data Mining of Association Rules

Discovery of association rules is a prototypical problem in data mining. The current algorithms proposed for data mining of association rules make repeated passes over the database to determine the commonly occurring itemsets or set of items. For large databases, the I/O overhead in scanning the database can be extremely...

InterWeave: A Middleware System for Distributed Shared State

As an alternative to message passing, Rochester's InterWeave system allows the programmer to map shared segments into programs spread across heterogeneous, distributed machines. InterWeave represents a merger and extension of the previous Cashmere and InterAct projects, combining hardware coherence within small multiprocessors, Cashmere-style lazy release consistency within tightly coupled clusters,...

New chip promises longer battery life

It always happens when you need it the most: the battery of you cellphone just died. But now, researchers of the University of Rochester have developed a wireless chip that needs ten times less power than current designs. The new chip relies on a technology named injection locked frequency divider...

Staffing and Routing in a Two-Tier Call Center

This paper studies service systems with gatekeepers who diagnose a customer problem and then either refer the customer to an expert or attempt treatment. The probability of successful treatment by a gatekeeper decreases as the problem's complexity increases. The authors determine the optimal staffing levels and referral rates that minimize...

A Taxonomy of Wireless Micro-Sensor Network Models

In future smart environments, wireless sensor networks will play a key role in sensing, collecting, and disseminating information about environmental phenomena. Sensing applications represent a new paradigm for network operation, one that has different goals from more traditional wireless networks. This paper examines this emerging field to classify wireless micro-sensor...

Scientists replicate the physics of a stellar jet in laboratory

Astronomers will tell you that among the most beautiful structures observed in the Universe are the intricate jets of matter speeding away from accreting stars, such as young proto-stars and stellar mass black holes. But they have a hard time explaining it. A pair of professors the University of Rochester...

Nehalem servers could spark a $27bn feeding frenzy

Nehalem servers could spark a $27bn feeding frenzyItanium doesn't stand a chance to NehalemOne things for sure (and probably why Intels Tukwila/Itanium has slipped by about a year) is that Itanium doesn't stand a chance against Nehalem and even when Tukwila does arrive, will have a tough ride against Nehalem-EX....

When bandwidth is free

If you haven't heard this already it bears repeating. (Picture from the University of Rochester.) Internet bandwidth is essential infrastructure. Like freeway lanes, like sea and airports, the quality and price of your Internet bandwidth determines how much it costs to do intellectual business...

Do squirrels really know how to avoid cancer?

University of Rochester researchers have discovered that small rodents with long lifespans, such as squirrels or chinchillas, can live decades without developing any form of cancer. Apparently, these rodents are using a previously unknown anti-cancer mechanism different from the ones used by humans or other large mammals. The lead researcher...

First true 3-D processor runs in labs

University of Rochester researchers have developed the first true 3-D processor and it runs today at 1.4 GHz. Previous attempts to build 3-D chips simply stacked identical processors on the top of one another. On the contrary, the new 3-D chip, dubbed the 'Rochester Cube,' was specifically designed to optimize...

A virus in our genes, think about that....

Really fascinating news: Virus is passed from parent to child in the DNA. Researchers found that roseola, an infection that everyone apparently gets but only 20 percent of children develop the characteristic rash that gives it its name, is actually in our DNA. It co-evolved into us, which raises some...
