In a distributed process control system, information about the behavior of physical processes is usually collected and stored in a real-time database which can be remotely accessed by human operators. In this paper we propose an analytic approach to compute the response-time distribution of operator consoles in a distributed process control environment. The technique we develop is based on Mark...

Replication is fundamental to science, so statistical analysis should give information about replication. Because p values dominate statistical analysis in psychology, it is important to ask what p says about replication. The answer to this question is "Surprisingly little." In one simulation of 25 repetitions of a typical experiment, p varied from <.001 to .76, thus illustrating that p is a ve...

Enumeration of the twin primes, and the sum of. their reciprocals, is extended to 3 x 1015 , yielding the count 1r2 (3 x 1015 ) = 3310517800844. A more accurate estimate is obtained for Brun 's constant, B2 = 1.90216 05823 ± 0.00000 00008. Error analysis is presented to support the contention that this estimate produces a 95 % confidence interval for B2 • In addition, published values of the co...

It has been pointed out that the construct of commitment plays a central role in business relationships. This article draws on the relationship marketing literature in order to construct a framework that can be used to investigate what motivates clients to continue their relationship with an audit ®rm. The results from an empirical study provide evidence for existence of a number of antecedents...

Novice drivers tend to restrict their search of the road on dual-carriageways, relative to the scanning observed in experienced drivers. The present study determined whether the difference was the result of novices having limited mental capacity remaining after vehicle control had been maintained, or whether it resulted from an impoverished mental model of the events likely to occur on a dual-c...

Two distinct mechanisms are often considered necessary to account for generation of the past-tense of English verbs: a lexical associative process for irregular forms like speak “ spoke, and a rule-governed process (‘add -ed ’) for regular and novel forms like talk “ talked and wug “ wugged. An alternative account based on a parallel-distributed processing approach proposes that one complex pro...

Telemanipulators have been introduced into cardiac surgery recently expanding the scope of minimally invasive techniques and enabling endoscopic cardiac surgery. Our aim was to evaluate clinical results of totally endoscopic single vessel bypass grafting on the arrested as well as on the beating heart. Since 1999, 44 totally endoscopic single vessel arterial bypass grafting procedures were perf...

Surface and structural damage to plasma-facing components due to the frequent loss of plasma confinement remains a serious problem for the tokamak reactor concept. The deposited plasma energy during major disruptions, edge-localized modes (ELMs), and vertical displacement events (VDEs) causes significant surface erosion, possible structural failure, and frequent plasma contamination. Surface da...

One of the most robust qualities of our visual world is the scale invariance of natural images. Not only has scaling been found in different visual environments, but the phenomenon also appears to be calibration-independent. This paper proposes a simple property of natural images which explains this robustness: they are collages of regions corresponding to statistically independent "objects". E...
