Forest operations such as harvesting, thinning, and site preparation can affect the hydrologic behavior of watersheds on poorly drained soils. The influence of these operations conducted on organic soil sites can be more pronounced than on mineral soil sites due to the differences in bulk density and soil moisture relationships that exist between mineral and organic soils. This article reports ...

Although the effects of gap formation resulting from thinning on microclimate, plant generation and understory plant community have been well documented, the impact of thinning on soil microbial community and related ecological functions of forests particularly in subalpine coniferous region is largely unknown. Here, the effects of thinning on soil microbial abundance and community structure us...

The objective of this research is to estimate location and size using laser ultrasound guided wave for wall thinning evaluation of elbow. Wall thinning of carbon steel pipe is one of the most serious problems in Nuclear Power Plant especially wall thinning of carbon steel elbow caused by FAC (Flow-Accelerated Corrosion). Therefore non-destructive inspection method of elbow is essential for safe...

Grape composition plays important role for wine grapes in terms of wine grape quality. Besides, monoterpenes are a chemical class of compounds present in many highly aromatic Vitis vinifera L. cultivars belonging to Muscat family and some other special cultivars. One of these special grape cultivars is Sauvignon Blanc, and in this study, cluster thinning and its treatment times were used for a ...

This study uses two regionwide data sets, one exemplified by intensive management and the other by nonintensive management, to investigate whether including regional locale and thinning response improves the loblolly pine height– diameter relationship. Results showed that including geographic coordinates as scaled variables, in addition to including a thinning response modifier, reduces the var...

PURPOSE To determine the nature and extent of regional cortical thinning in patients with mesial temporal lobe epilepsy (MTLE). METHODS High-resolution volumetric MRIs were obtained on 21 patients with MTLE and 21 controls. Mean cortical thickness was measured within regions of interest and point-by-point across the neocortex using cortical reconstruction and parcellation software. RESULTS ...

Topological skeletons are shape descriptors that have been applied successfully in practical applications. However, many skeletonisation methods lack accessibility, mainly due to the need for manual parameter adjustment and the shortage of tools for comparative analysis. In this paper we address these problems. We propose two new homotopypreserving thinning algorithms: Flux-ordered adaptive thi...

[1] Mixing ratios and emission rates of monoterpenes were measured above a ponderosa pine plantation in the Sierra Nevada mountains before, during and after a precommercial thinning in spring 2000. The thinning removed and left onsite approximately one half of the plantations biomass. Monoterpene fluxes increased tenfold during the thinning and pinene mixing ratios in excess of 3 ppb were obser...

In this paper, we propose a new methodology to conceive a thinning scheme based on the parallel deletion of P-simple points. This scheme needs neither a preliminary labelling nor an extended neighborhood, in the opposite of the already proposed thinning algorithms based on P-simple points. Moreover, from an existent thinning algorithm A, we construct another thinning algorithm A′, such that A′ ...

This review paper provides a concise survey on different techniques for thinning and their comparison in image processing. Thinning is one of the fundamental requirements is to represent the structural shape of digital images. This can be done by reducing it to a graph. This process may be completed by obtaining the skeleton of the particular region of the image or the full image using skeleton...
