The Chair of the IEEE Computer Society Technical Committee on Data Engineering (TCDE) is elected for a two-year period. The current Chair, Paul Larson, is unavailable to be a candidate. A Nominating Committee for electing a new chair for the period 2011-2012 consisting of Calton Pu, David Lomet and Erich Neuhold has been formed. The Nominating Committee invites nominations for the position of C...

Recently, several reversible information hiding methods based PVO (pixel value ordering) techniques have been proposed, in these methods, secret data always are embedded in pixels with largest or smallest value in the block. In order to make use of the block with multiple largest-valued (or smallest-valued) pixels, a PVO-K method was proposed, which treats K largest-valued (or smallest-valued) ...

In a previous paper the CSCR domain was defined. Here this is taken to the next stage where we consider the design of a particular Collaborative Research Environment to support Students and Supervisors CRESS. Following the CSCR structure a preliminary design for CRESS has been established and a portal framework analysis is undertaken in order to determine the most appropriate set of tools for i...

Discrepancies between assumed dynamical models and observations are often handled by making further probabiIistic assumptions, a tactic which has both strengths and weaknesses. A re-examination of filtering and smoothing is conducted, and an alternative multicriteria approach, which is probability free, is advanced. This approach involves vector minimization as a key ingredient, and it speciali...

Encouraging people to consider multiple alternatives appears to be a useful debiasing technique for reducing many biases (explanation, hindsight, and overconfidence), if the generation of alternatives is experienced as easy. The present research tests whether these alternative generation procedures induce a mental simulation mind-set (cf. Galinsky & Moskowitz, 2000), such that debiasing in one ...

The DARPA Internet uses the Domain Name Sys tem DNS a distributed database to map host names to network addresses and vice versa Using a vulnerability rst noticed by P V Mockapetris we demonstrate how the DNS can be abused to sub vert system security We also show what tools are useful to the attacker Possible defenses against this attack including one implemented by Berkeley in re sponse to our...

We replicate Moskowitz and Grinblatt’s (1999) findings on industry momentum using data for US large cap stocks between 1998 and 2007. Moskowitz and Grinblatt find that industry momentum strategies appear to be highly profitable. Moskowitz and Grinblatt also demonstrate that individual stock momentum strategies, which buy past winning stocks and sell past losing stocks, are less profitable after...

In the increasingly rare segment, the stage curtain is raised to reveal an individual or team performing an unusual stunt, often accompanied by music from the CBS Orchestra ... after about thirty seconds the curtain is lowered and Letterman discusses with [Paul] Shaffer whether the act was ‘something’ or ‘nothing’ ... it was resurrected on the March 22, 2006, episode.
