Judy Robertson writes about researchers' use of the wrong statistical techniques to analyze attitude questionnaires.
Computer scientists are teaching machines to run experiments, make inferences from the data, and use the results to conduct new experiments.
Thanks to new research initiatives, autonomous humanoid robots are inching closer to reality.
Virtual possessions play an increasingly important role in our daily lives. How we think about them and deal with them is changing the way we think and interact with others.
The success of Germany's Dagstuhl Seminars has inspired a proliferation of Dagstuhl-like venues, especially in India.

Say you want to simulate the motion over time of the stars in a galaxy to learn about how galaxies formed and why the universe appears as it does. Is it feasible on a single processor? Sadly, even using today's fastest single …
We describe a parallel fast multipole method for highly nonuniform distributions of particles. We employ both distributed memory parallelism and shared memory parallelism to rapidly evaluate two-body nonoscillatory potentials …

It is widely held that parallel programming is far more difficult and error prone than writing sequential code. In particular, the myriad allowable interleavings of thread execution mean that different runs of a program can …
We introduce a new parallel programming model addressing the issues facing current methods of executing parallel
programs deterministically, and use Determinator, a proof-of-concept OS, to demonstrate the model's practicality …
