Temporal Patterns for Burglar Alarms and Police-coded Burglaries
… This dissertation considers that the timing patterns for alarm occurrence might provide a window into the timing patterns by which burglaries themselves occur. The researcher examines and compares detailed patterns for alarms as well as other evidence of burglary timing, including burglary …

Vegetation ecology of springs: ecological, spatial and temporal patterns
… is an appropriate tool to detect spatial and temporal patterns of ecosystem alterations, such as acidification and recovery. However, to know the interrelationships between organisms and their environment is an indispensable precondition for the identification of indicator species. The …

Dynamics of stochastic spatial-temporal patterns in transitional turbulence
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-12-01

Spatial-temporal patterns in evolutionary ecology and fluid turbulence
… both highly non-equilibrium and exhibit spatio-temporal complexity during the course of their evolution. It might seem that they are too complicated to extract universal properties, even if there are any. Surprisingly, it turns out that each of them can shed light on the other, enabling them …

Sketch interpretation using multiscale stochastic models of temporal patterns
… extracting as much information as possible from temporal patterns that appear during sketching.

Spatio-Temporal Patterns, Correlations, and Disorder in Evolutionary Game Theory
… Monte Carlo simulations to study emerging spatio-temporal patterns, spatial correlations, and the influence of quenched spatial disorder in rock-paper-scissors systems either with or without conserved total population number. In balanced rock-paper-scissors systems far away from the ``corner'' of …

Spatio-Temporal Patterns of Biodiversity and their Drivers - Method Development and Application
Landnutzungsveränderungen und Klimawandel führen weltweit zu einer rapiden Veränderung von Landschaften und Ökosystemen. Es werden dringend standardisierte und vergleichbare Daten benötigt, um den damit einhergehenden Verlust von Biodiversität zu erfassen. Daher ist es überaus wichtig, Methoden für …

Modelling the Transmission of Dengue Fever Based on Spatial and Temporal Patterns
… and vector interactions result in complex spatiotemporal patterns in dengue disease. Moreover, it has been previously indicated that the dengue fever epidemic is due to several climatic, social, environmental, and biological factors, and these factors vary from place to place and with time. …

Soft sediment ecology of Lough Hyne Marine Reserve - spatial and temporal patterns
… to investigate changes across spatial and temporal scales. Investigations took place at Lough Hyne Marine Reserve using a range of methods. Data on the sedimentation rates of organic and inorganic matter were collected at monthly intervals for one year at a number of sites around the Lough, …

Environmental variables influencing spatial and temporal patterns of fish spawning and recruitment
… collected from the literature. The comparison of temporal patterns in spawning of South African fish species showed variable spawning times and intensity depending on the environmental conditions within that spawning habitat. Their spawning migration durations were suggested to be short since they …

The effect of telecommuting on the temporal patterns of managers and employees
… interest are how teleworking has changed temporal patterns associated with work and how these changes have affected interactions between teleworkers and those with whom they work. This thesis explores these issues through interviews with both teleworkers themselves and their colleagues and …

Spatial and Temporal Patterns of Areal and Volumetric Phytoplankton Productivity of Lake Texoma
Phytoplankton productivity of Lake Texoma was measured for one year from August 1999 to August 2000 for four stations, using the oxygen change method and laboratory incubation. Mean values of the photosynthetic parameters, PBmax and alphaB ranged from 4.86 to 46.39 mg O2.mg Chl-1.hr-1 for PBmax and …

Spatial and temporal patterns of visibility in Las Vegas, July 2000--July 2001
… and background/transport. Strong diurnal patterns were found at the urban and suburban sites. The background site had low levels of air pollution, and most of the haze at this site was due to light scattering by particles. The suburban site followed a well-defined diurnal pattern during …

Recognition and investigation of temporal patterns in seismic wavefields using unsupervised learning techniques
… The latter allows the recognition of wavefield patterns, such as short-term transients and long-term variations, with a minimum of domain knowledge. Besides classical earthquake seismology, investigations of temporal patterns in seismic data also concern novel approaches such as noise …

Learning, Recognizing and Early Classification of Spatio-Temporal Patterns using Spike Timing Neural Networks
Learning and recognizing spatio-temporal patterns is an important problem for all biological systems. Gestures, movements, activities, all encompass both spatial and temporal information that is critical for implicit communication and learning. This dissertation presents a novel, unsupervised …
