Information on individual tree attributes is important for sustainable management of forest stands. Airborne Laser Scanning (ALS) point clouds are an excellent source of information for predicting a range of forest stand attributes, with plot and single tree volume being among the most important. Two approaches exist for estimating volume: area-based approach (ABA) and individual tree detection...

Crow-AMSAA (CA) plots are used to model reliability growth. Use of CA plots has expanded into other areas, such as tracking events of interest to management, maintenance problems, and safety mishaps. Safety mishaps can often be successfully modeled using a Poisson probability distribution. CA plots show a Poisson process in log-log space. If the safety mishaps are a stable homogenous Poisson pr...

In Bhutan the Persian Walnut (Juglans regia L.) is highly valued for its timber and listed under special class in Royalty on Forest Products of Bhutan. Possessing high other medicinal values, ecology species country was poorly understood. The study aimed to understand ecological requirements habitat modeling A purposive non-probability sampling adopted natural habitats four districts (Gasa, Pun...

To compare several promising product designs, manufacturers must measure their performance under multiple environmental conditions. In many applications, a product design is considered to be seriously flawed if its performance is poor under any level of the environmental factor. For example, if a particular automobile battery design does not function well under some temperature conditions, then...

Satellite handover happens frequently in Low Earth Orbit (LEO) satellite network due to satellite’s high mobility. In this paper, we propose a novel call admission control scheme which utilizes both the geographical information and the distance between the new call’s position and the preparing handover user’s position in the previous plot beam to intelligently decide whether to block a new call...

Despite the fact that erosion undermines productivity in the Ethiopian highlands, adoption of fertility enhancing techniques remained very minimal. The objectives of this study is to examine factors affecting adoption of fertilize and manure use and their interrelationships using plot and household level data collected from 211 farm households. A two-stage probit model results revealed a negati...

Background To review the multifocal visual evoked potential (mfVEP) technique and to illustrate its use in neuroophthalmology. Methods Monocular mfVEP recordings were obtained from both eyes. The display, 44.5° in diameter, contained 60 sectors. Each sector was a pattern-reversing checkerboard. Probability plots, analogous to the probability plot of the Humphrey Visual Field (HVF) Analyzer, wer...

The joint probability distribution of states of many degrees of freedom in biological systems, such as firing patterns in neural networks or antibody sequence compositions, often follows Zipf's law, where a power law is observed on a rank-frequency plot. This behavior has been shown to imply that these systems reside near a unique critical point where the extensive parts of the entropy and ener...

Performance standards for detector systems often include requirements for probability of detection and probability of false alarm at a specified level of statistical confidence. This paper reviews the accepted definitions of confidence level and of critical value. It describes the testing requirements for establishing either of these probabilities at a desired confidence level. These requiremen...
