The intermediate disturbance hypothesis predicts that the highest diversity will occur at levels of moderate disturbance. We measured the species diversity, abundance, and species diversity of bacteria on the human body in relation to disturbance by washing. Bacteria were sampled from three surfaces on the human body with varying disturbances, counted, and classified into morphospecies. The sit...
The main contribution of this paper is to provide a classification of disturbance vectors used in differential collision attacks against SHA-1. We show that all published disturbance vectors can be classified into two types of vectors, type-I and type-II. We present a deterministic algorithm which produce efficient disturbance vectors with respect to any given cost function. We define two simpl...
The intriguing history of disturbance cancellation control is reviewed in this thesis first, which demonstrates that this unique control concept is both reasonable and practical. One novel form of disturbance cancellation, ADRC (Active Disturbance Rejection Control), attracts much attention because of its good disturbance rejection ability and simplicity in implementation. Hydraulic systems ten...
The identification of disturbance thresholds is important for many aspects of aquatic resource management, including the establishment of regulatory criteria and the identification of stream reference conditions. A number of quantitative or model-based approaches can be used to identify disturbance thresholds, including nonparametric deviance reduction (NDR), piecewise regression (PR), Bayesian...
In recent years, emotion dysregulation and anxiety sensitivity have been introduced of the most effective factors in sleep disturbance. The purpose of this study was to examine emotion dysregulation and anxiety sensitivity as potential contributor to sleep problems in students. The statistical population of this research consisted of all the Bu-Ali Sina University’s students in the academic yea...
Article history: Received 26 December 2006 Received in revised form 8 February 2008 Accepted 9 February 2008 Forest disturbance and recovery are critical ecosystem processes, but the spatial pattern of disturbance has never been mapped across North America. The LEDAPS (Landsat Ecosystem Disturbance Adaptive Processing System) project has assembled a wall-to-wall record of stand-clearing disturb...
