ADtrees, a data structure useful for caching sufficient statistics, have been successfully adapted to grow lazily when memory is limited and to update sequentially with an incrementally updated dataset. For low arity symbolic features, ADtrees trade a slight increase in query time for a reduction in overall tree size. Unfortunately, for high arity features, the same technique can often result i...

where χ is a non-trivial additive character of the finite field Fq, q = p odd, and a ∈ Fq . In my dissertation [5], in particular in [4], I considered more generally the sums S(a,N) for all factors N of p+1. The aim of the present note is to evaluate S(a,N) in a short way, following [4]. We note that our result is also valid for even q, and the technique used in our proof can also be used to ev...

The growing importance of real-time computing in numerous applications poses problems for network architectures, especially safety-critical Wide Area Networks (WANs). Assessing network performance in safety-critical real-time systems is difficult, and suggests the use of both human and technical performance criteria because of the importance of both dimensions in safety-critical settings. This ...

Tidal harmonic analysis simulations along with simulations spanning four specific historical time periods in 2003 and 2004 were conducted to test the performance of a northern Gulf of Mexico tidal model. A recently developed method for detecting inundated areas based on integrated remotely sensed data (i.e., Radarsat-1, aerial imagery, LiDAR, Landsat 7 ETM+) was applied to assess the performanc...

This paper presents a comparison of two versions of an Emergency Automated Response System (EARS), a fully manual version and a partially automated version. User evaluations involving both versions of the system were conducted using a low workload task and a high workload task. The results indicate that the automation employed by the partially automated system decreased overall response time an...

Huet and Levy pioneered lazy sequential evaluation of equational programs based on the concepts of strong-sequentiality and needed redexes. Natural extensions of their strategy are not well-suited for parallel evaluation since they do not support independent searches for needed redexes along diierent paths in the input term. Furthermore, the size of compiled code can be exponential in program s...

Recent advances of physical communication media allow data transmissions at very high transmission capacity and low error rates. Concurrent to this evolution, an increase interest in real-time and mul-timedia applications can be seen in science, medicine, manufacturing, as well as entertainment. The design, planning and construction of these new communication structures can be supported in an e...

The issue of computing (co)homology generators of a cell complex is gaining a pivotal role in various branches of science. While this issue can be rigorously solved in polynomial time, it is still overly demanding for large scale problems. Drawing inspiration from low-frequency electrodynamics, this paper presents a physics inspired algorithm for first cohomology group computations on three-dim...

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...

appearing in Cronon’s oft-cited collection Uncommon Ground were focused more on coming to terms with the consequences of the cultural mediation of our knowledge of nature and models of ecological change in postwar environmentalism, Cronon’s own dismantling of the meanings and images associated with the American wilderness idea suggested that the earlier conservation movement was also implicated...
