Abstract In Jutten’s blind separation algorithm, symmetrical distribution and statistical independence of the signal sources are assumed. When they are not satisfied, the learning process becomes unstable. In order to avoid the unstable behavior, two stabilization methods are proposed. Since large samples easily disturb symmetrical distribution, the outputs of the separation process with large ...

We develop tools to study the problem of containment of symbolic powers I(m) in powers I for a homogeneous ideal I in a polynomial ring k[P ] in N + 1 variables over an arbitrary algebraically closed field k. We obtain results on the structure of the set of pairs (r, m) such that I(m) ⊆ I. As corollaries, we show that I2 contains I(3) whenever S is a finite generic set of points in P2 (thereby ...

Climate change litigation has emerged as a powerful tool societies steer towards sustainable development. Although the mainly takes place in domestic courts, implications can be seen global specific climate rulings influence courts across national borders. However, while phenomenon of judicialization is well-known social sciences, relatively few have studied issues legitimacy that arise politic...

We provide a simple model to investigate decisions about vertical separation. The key feature of this model is that more than one input is required for the final product of the downstream monopolist. We show that as the bargaining powers of independent complementary input suppliers grow larger, the downstream monopolist tends to separate from its input units. The results are related to a visibl...

Privilege user is needed to manage the commercial transactions, but a super-administrator may have monopolize power and cause serious security problem. Relied on trusted computing technology, a privilege separation method is proposed to satisfy the security management requirement for information systems. It authorizes the system privilege to three different managers, and none of it can be inter...

The UT Austin Villa 2003 simulated online soccer coach was a first time entry in the RoboCup Coach Competition. In developing the coach, the main research focus was placed on treating advice-giving as a learning problem. The coach learns to predict agent behavior from past observations and automatically generates advice to improve its team’s performance. Using this approach, the UT Austin Villa...
