Open Source: The Dark Horse of Software?
|
|
In 1983, Richard Stallman created a Unix-like operating system called GNU (a recursive acronym for “GNU is Not Unix”) and released it under a license that provided certain rights for use and redistribution - an open-source license. Eight years later, a graduate student at the University of Helsinki, Linus Torvalds, created another Unix-like operating system, Linux, which he also made available for free.

The Nonequispaced FFT: An Indispensable Algorithm for Applied Science
|
|
Fast Fourier transforms (FFTs) are one of the "10 algorithms with the greatest influence on the development and practice of science and engineering in the 20th century" [1]. This is because the FFT is applied in almost every area of modern science, including fields as diverse as acoustics, astronomy, computational biology, fluid dynamics, medicine, physics, and digital signal processing.

The Critical Need for Computational Intelligence in Human Genetics
|
|
An important goal of human genetics is to identify which genes and which specific DNA sequence variations (polymorphisms) play an important role in determining susceptibility to common diseases such as cancer, essential hypertension, and schizophrenia. -

Adversarial Information Retrieval: The Manipulation of Web Content
|
|
Adversarial information retrieval has become a very active research area
in the last few years. As the name indicates, adversarial information retrieval research differs
from traditional information retrieval in that the content providers may have an adversarial relationship
with the entity (usually a search engine) that consumes their content. - Dennis Fetterly

Game Theory and the Design of Electronic Markets
|
|
Game theory is the study of decision making among multiple agents
(human or software). In a game, the decisions of all agents jointly determine the
outcome. An auction is a classic example of a game: the bids of all participants
determine the winner and the winning price. This essay illustrates some of the features
and bugs in the design of electronic consumer auctions. - Amy Greenwald

Autonomous Virtual
Characters: Realistic Inhabitants of Artificial Worlds
|
|
Virtual characters, also known as virtual actors, have become
very popular in the last ten years, mainly through three-dimensional
(3D) movies and games. In movies, they now have very realistic
physical and emotional characteristics, including their facial
expressions, hair, clothes, and motions. - Nadia Magnenat-Thalmann and Daniel Thalmann

Managing the Unmanageable: Putting Cryptography to Work for Digital Rights
|
|
The advantages of digital content distribution (DCD) include rapid
dissemination on a global scale, cost-effectiveness, unparalleled
production capabilities, and highly flexible pricing. However, the ease
and convenience of storing and transmitting data in digital form is a
double-edged sword. - Aggelos Kiayias

Brain
Machine Interfaces: Mind over Matter
|
|
Our brains use our bodies to interact with the external
world. However, emerging technology is poised to challenge this state
of affairs and create direct brain machine interfaces (BMIs) to open
up a digital channel between the brain and the physical world. - José

| Overlay
Networks: Networking on Top of the Network |
|
| During the last six years, overlay networks have
become one of the most prominent tools for Internet research and development.
Overlays permit designers to implement their own routing and packet
management algorithms on top of the Internet. - David G. Andersen |
