High-resolution niche models via a correlative approach: Comparing and combining correlative and process-based information

Victor Bogosian III, Eric C. Hellgren, Michael W. Sears, Raymond W. Moody
2012 Ecological Modelling  
Correlative and process-based approaches to describing the ecological niche in a spatially explicit fashion have often been compared in an adversarial framework.  ...  Process-based information continues to be an important part of the niche, and may offer additional predictive accuracy via correlative approaches when included in an ecologically meaningful context.  ...  not be easily expressed in a correlative modeling approach or combined with temporally coarser habitat GIS layers.  ...

Abstracts - Keynote Lectures

2010 Alcoholism: Clinical and Experimental Research  
The special emphasis is paid to phase methods which require to design of FP features such as temporal and spatial carrier frequency or phase shifts.  ...  The paper is intended to be a review of fringe pattern analysis methods, FPA, and their capabilities to analyse an extended class of images.  ...  The other recent tendency in fringe pattern analysis methods is to form hybrid methods which combine advantages of the well known approaches including: • spatial and temporal heterodyning 6 .  ...

Parallel Processing Strategies for Big Geospatial Data

Martin Werner
2019 Frontiers in Big Data  
This paper provides an abstract analysis of parallel processing strategies for spatial and spatio-temporal data.  ...  Throughout this discussion, the need for a replacement or extension of the MapReduce paradigm for spatial data is derived.  ...  One example of this class is ALT search (Goldberg and Harrelson, 2005) which has won the ACM SIGSPATIAL GIS Cup 2015 in a shared memory multiprocessing setting for dynamic street networks (Werner, 2015  ...

Phase transition and computational complexity in a stochastic prime number generator

L Lacasa, B Luque, O Miramontes
2008 New Journal of Physics  
We finally relate the nature of the phase transition to an average-case classification of the problem.  ...  Further on we redefine the model as a search problem, fitting it in the hallmark of computational complexity theory. We suggest that the system belongs to the class NP.  ...  Chaos in a cup of flour.  ...

Intersexual spatial relationships in a lekking species: blue-crowned manakins and female hot spots

Renata Durães, Bette A. Loiselle, John G. Blake
2007 Behavioral Ecology  
Leks offer an intriguing evolutionary problem: why do males aggregate when this apparently leads to fitness costs?  ...  Our results indicate that this lack of spatial correlation between males and females results partly from differences in sex-specific habitat preferences.  ...  We thank Dr Patricia Parker for sharing the facilities of the Molecular Genetic Laboratory in Zoological Studies at the Department of Biology/University of Missouri-St Louis and K Halbert for her invaluable  ...

A Review of Rule Learning Based Intrusion Detection Systems and Their Prospects in Smart Grids

Qi Liu, Veit Hagenmeyer, Hubert B. Keller
2021 IEEE Access  
The evaluation on a subset of KDD CUP 99 dataset shows that their approach has an accuracy above 90% for all types of attacks, but suffers from a very high false positive rate for privilege escalation  ...  A common approach is to introduce an objective function that evaluates each network structure using training data, and then to search for the best Bayesian network according to this objective function  ...

Mapping neural networks onto message-passing multicomputers

Joydeep Ghosh, Kai Hwang
1989 Journal of Parallel and Distributed Computing  
The structural model offers an efficient methodology for mapping virtual neural networks onto a real parallel computer.  ...  Until the technology for direct hardware implementation of large neural networks is available, simulation remains the most viable alternative for the connec-tion& community.  ...  For more randomly structured networks, simple techniques developed for partitioning of graphs [ 371 prove effective.  ...
