This paper presents a tuturial introduction to predictions of stock time series. The various approaches of technical and fundamental analysis is presented and the prediction problem is formulated as a special case of inductive learning. The problems with performance evaluation of near-random-walk processes are illustrated with examples together with guidelines for avoiding the risk of data-snoo...

The Chip Multiprocessor (CMP) architecture offers dramatically faster retrieval of shared data which is cached on-chip rather than in an off-chip memory. Remote cache requests are handled through a cache coherence protocol. In order to obtain the best possible performance with the CMP architecture, the cache coherence protocol must be optimized to reduce time lost during remote cache and offchi...

ater bodies fed by current or former industrial, agricultural, or mining areas frequently contain contaminated sediments, and throughout the U.S., miles of riverbeds and vast areas of harbors, lakes, and estuaries are affected (1, 2). Contaminants in sediments can have direct toxic effects on organisms and can accumulate in organisms consumed by humans. The presence of sediment contamination al...

OBJECTIVE To observe the changes of peristalsis of small intestine in guinea pigs after administration of traditional Chinese medicines activating blood to resolve stasis (Compound Danshen Decoction, CDSD) or/and medicines dredging intestines (Dachengqi Decoction, DCQD), and to explore the synergetic or intensive effect of CDSD on DCQD. METHODS By means of BL-420 Biological Experimental Syste...

LPS (Logic-based Production System) is a framework that combines logic programs with reactive rules and a destructivelyupdated database. The logic programs provide proactive behavior and allow definitions of processes, and the reactive rules provide reactive behavior. This paper describes a first attempt in using LPS to model the operations of cutter suction dredging (CSD). It is the result of ...

We report evidence on the profitability and statistical significance among 2,127 technical trading rules. The best rules are found to be significantly profitable based on standard tests. We then employ White’s (2000) Reality Check to evaluate these rules and find that data-snooping biases do not change the basic conclusions for the full sample. A sub-sample analysis indicates that the data-snoo...

December 2006 | Volume 4 | Issue 12 | e418 Most governments around the world set conservation policy based on the assumption that resource exploitation and species protection can co-exist in the same place. These policies have led to Orwellian “marine protected areas” that host commercial fi shing operations, leading one to wonder who’s protecting whom. A new study reveals the danger of this ap...
