String regularities such as repetition, palindrome, period, seed, square, cover, etc., have been studied extensively recently. Particularly, string regularities play an important role of applications in bioinformatics tools. For a given string, its quasiperiod is the cover with the minimum length, which can be used in the hybridization method in DNA sequencing. Many algorithms have been propose...

Many fire disasters have occurred on the thermoplastic expanded polystyrene (EPS) external thermal insulation composite systems (ETICS) installed vertically building facade. Thus, it is important to understand reaction-to-fire performance of EPS ETICS and effect sample scale, orientation, masonry cover in tests. In this work, both specimens alone with are tested under three different scales, (1...

one of the most important information in urban forestry is acquaintance of urban landscape’s area or proportion. nowadays, in several countries variable methods are used to achieve this aim. since there is not any complete method to study urban forest’s status in iran, it is impossible to exert authentic management for these resources. hence, in this research, sampling methods and ikonos satell...

RESUME The paper presents the results of land cover and crops identification achieved on the basis of the time series of 27 ENVISAT -1/ ASAR images acquired in Image Mode and Alternating Polarization Mode during the 2003 observing campaign for Malbork test site in northern Poland. The results are compared with those obtained from SPOT -4 multitemporal data. High degree of their similarity has b...

BACKGROUND The purpose of this study was to evaluate the efficacy of a quantitative analysis method for comitant exotropia using video-oculography (VOG) with alternate cover. METHODS Thirty-four subjects with comitant exotropia were included. Two independent ophthalmologists measured the angle of ocular deviation using the alternate prism cover test (APCT). The video files and data of changes...

Google Earth (GE) releases free images in high spatial resolution that may provide some potential for regional land use/cover mapping, especially for those regions with high heterogeneous landscapes. In order to test such practicability, the GE imagery was selected for a case study in Wuhan City to perform an object-based land use/cover classification. The classification accuracy was assessed b...

Ice-core records show that climate changes in the past have been large, rapid, and synchronous over broad areas extending into low latitudes, with less variability over historical times. These ice-core records come from high mountain glaciers and the polar regions, including small ice caps and the large ice sheets of Greenland and Antarctica.
