Is Web-Based Supply Chain Integration Right For Your Company?
Companies are increasingly realizing that the progression from departmental to enterprise information systems has a logical next step: inter-organizational or supply chain solutions.
Technical Perspective: Learning to Act in Uncertain Environments
The problem of decision making in an uncertain environment arises in many diverse contexts. The key issue in effectively solving problems like this is known as the exploration/exploitation trade-off.
Cloud Computing and Developing Nations
For a growing number of organizations worldwide, cloud computing offers a quick and affordable way to tap into IT infrastructure as an Internet service. But obstacles and challenges remain.
Advances in computer technology have changed the way astronomers see and study the universe.
Why Cloud Computing Will Never Be Free
The competition among cloud providers may drive prices downward, but at what cost?
Enhanced Debugging With Traces
An essential technique used in emulator development is a useful addition to any programmer's toolbox.
Censored Exploration and the Dark Pool Problem
The success and proliferation of dark pool stock exchanges have created challenging and interesting problems in algorithmic trading—in particular, the problem of optimizing the allocation of a large trade over multiple competing dark pools.
