In the last decade, prediction markets became popular forecasting tools in areas ranging from election results to movie revenues and Oscar nominations. One of the features that make prediction markets particularly attractive for decision support applications is that they can be used to answer “what if” questions and estimate probabilities of complex events. Traditional approach to answering suc...

The threat of cyber-attacks grows up, as one can see by several negative security news and reports [8]. Today there are many security components (e.g. anti-virus-system, firewall, and IDS) available to protect enterprise networks; unfortunately, they work independently from each other – isolated. But many attacks can only be recognized if logs and events of different security components are com...

Although many researches have been carried out to analyze laboratory test errors during the last decade, it still lacks a systemic view of study, especially to trace errors during test process and evaluate potential interventions. This study implements system dynamics modeling into laboratory errors to trace the laboratory error flows and to simulate the system behaviors while changing internal...

A low power adaptive digital baseband architecture is presented for a low-IF receiver of IEEE 802.15.4-2006. The digital section’s sampling frequency and bit width are used as knobs to reduce the power under favorable signal and interference scenarios, thus recovering the design margins introduced to handle the worst case conditions. We show that in a 0.13 μm CMOS technology, for an adaptive di...

ince the advent of computing, the world has experienced an information " big bang " : an explosion of data. The amount of information being created is increasing at an exponential rate. Since 2003, digital information has accounted for 90 percent of all information produced [1], vastly exceeding the amount of information on paper and on film. One of the greatest scientific and engineering chall...

In fact, the development of a fully operational GIS for forest management will likely incorporate each activity as two distinct stages in its development (see Crain and MacDonald 1983, Jordan and Erdle 1990). For example, spatial data input, editing, and simple maps characterize the inventory and monitoring stage. In the modeling stage, overlays, reclassifications and suitability analyses are i...
