Brown University economists measure GDP growth from outer space

For many developing countries, the data for measuring economic growth is unreliable or incomplete. In response, a team of economists at Brown have suggested a new framework for estimating a country or region’s gross domestic product GDP by using satellite images of the area’s nighttime lights. by Chris Jablonski

A Comparison of Stream-Oriented High-Availability Algorithms

Recently, significant efforts have focused on developing novel data-processing systems to support a new class of applications that commonly require sophisticated and timely processing of high-volume data streams. Early work in stream processing has primarily focused on stream-oriented languages and resource-constrained, one-pass query-processing. High availability, an increasingly important goal for...

Energy-Aware Microprocessor Synchronization: Transactional Memory Vs. Locks

One important way in which multiprocessors differ from uniprocessors is in the need to provide programmers the ability to synchronize concurrent access to memory. Transactional memory was proposed as a way of improving throughput especially when the rate of synchronization conflict is low. This paper explores power implications of transactional...

Optic flow guides us in the right direction

The way we perceive the visual motion of objects as we move is a phenomenon called 'optic flow.' Now, Brown University researchers have discovered that optic flow helps us to walk. They've used Brown's Virtual Environment Navigation Lab, or VENLab, one of the largest virtual reality labs in the U.S....

Programming Languages: Application and Interpretation

This paper is the fruit of a vision for teaching programming languages by integrating the "Two cultures" that have evolved in its pedagogy. One culture is based on interpreters, while the other emphasizes a survey of languages. Each approach has significant advantages but also huge drawbacks. The interpreter method writes...

A Cooperative, Self-Configuring High-Availability Solution for Stream Processing

This paper presents a collaborative, self-configuring High Availability HA approach for stream processing that enables low-latency failure recovery while incurring small run-time overhead. The approach relies on a novel fine-grained check-pointing model that allows query fragments at each server to be backed up at multiple other servers and recovered collectively...

Plastic batteries coming soon?

Engineers at Brown University have built a prototype of an hybrid plastic battery that uses a conductive polymer. The system, which marries the power of a capacitor with the storage capacity of a battery, can store and deliver power efficiently. For example, during performance testing, "it delivered more than 100...
