Forest fires have profound impacts on the spatial distribution of vegetation type and density. This research analyzes the impacts of the 2002 Ponil Fire in New Mexico on landscape patterns using a moving-window analysis of landscape metrics. Categorically derived landscape metrics and a measure of fire severity—the Normalized Burn Ratio—are used to produce a quantitative, spatial distribution o...

When modeling time series data using autoregressive-moving average processes, it is a common practice to presume that the residuals are normally distributed. However, sometimes we encounter non-normal residuals and asymmetry of data marginal distribution. Despite widespread use of pure autoregressive processes for modeling non-normal time series, the autoregressive-moving average models have le...

Recent years have witnessed a growing interest in the fields of video surveillance and mobile object tracking. This paper proposes a mobile object tracking algorithm. First, several parameters such as object window, object area, and expansion-contraction (E-C) parameter are defined. Then, a modified E-C algorithm for multiple-object tracking is presented. The proposed algorithm tracks moving ob...

The known ore deposits and mineralization trends are important key exploration criteria in mineral exploration within a specific region. Fry analysis has conventionally been considered as a suitable method to determine the mineralization trends related to linear structures. Based upon literature sources, to date, no investigation has been carried out that includes the Sensitivity Analysis of Fe...

This paper proposes implementations of the well-known traffic policing mechanisms for high speed networks. The implementations are based on a high performance development environment and are described through commented block diagrams. The considered mechanisms are Leaky Bucket with variants, Jumping Window, Triggered Jumping Window, Continuous Sliding Window, Discretized Sliding Window and Time...

This paper presents a new computer-based teleconference system. In order to build the system, we modified VNC(Virtual Network Computing) program and implemented Face mouse system. Face mouse is a mouse pointer that is followed by face video. It has multiple functions of video communication channel, mouse identification, and a connection between face window and a shared working space. By moving ...

PURPOSE In order to assess whether focal epileptic seizures can be detected and distinguished from exercise we evaluated four different heart rate variability (HRV) methods with short term moving window analysis of 30, 50 or 100 R-R intervals or seconds per analyzed window. METHODS The four methods consisted of: (1) reciprocal high frequency power based on Fast Fourier Transformation, (2) Car...

An effective method for finding the relevant number (window size) and the elapsed time (window age) of recently completed projects has proven elusive in software effort estimation. Although these two parameters significantly affect the prediction accuracy, there is no effective method to stratify and sample chronological projects to improve prediction performance of software effort estimation m...
