The Directed Layering Problem (DLP) solves a step of the widely used layer-based approach to automatically draw directed acyclic graphs. To cater for cyclic graphs, usually a preprocessing step is used that solves the Feedback Arc Set Problem (FASP) to make the graph acyclic before a layering is determined. Here we present the Generalized Layering Problem (GLP), which solves the combination of ...

Airborne LiDAR point cloud of a forest contains three dimensional data, from which vertical stand structure (including information about under-story trees) can be derived. This paper presents a segmentation approach for multi-story stands that strips the point cloud to its canopy layers, identifies individual tree segments within each layer using a DSM-based tree identification method as a buil...

ASTRAL is a high-level formal speciication language for real-time systems. It includes structuring mechanisms that allow one to build modularized speciications of complex real-time systems with layering. Based upon the ASTRAL symbolic model checker reported in DK99b], an approximation technique to speed-up the ASTRAL symbolic model checker for debugging a speciication is presented. The techniqu...

Background: The advantages of the PFM systems are to combine fracture resistance metal substructure with aesthetic property porcelain. present study compared shear bond strength ceramic material veneered zirconia core by layering and pressing techniques.Materials Methods: 50 samples blocks were divided into 2 groups. Each group consisted 25 samples. In I, over technique in II, was used. loaded ...

The present study in formulation and evaluation of Mebeverine hydrochloride micropellets. Mebeverine hydrochloride which is used as a anti spasmodic drug to treat irritable bowel syndrome. The pellets were prepared by pan coating powder layering method by using nonpareil seeds in core pellets and were coated with HPMC K4M, Eudragit S100 and Eudragit L100 in different ratios to form a film coat ...

Filtering Random Layering Effects for Imaging and Velocity Estimation

Data transport services are flourishing at the intra-domain level. Despite that, things look much worse when we try to cross a domain boundary. Operators are endlessly tuning Border Gateway Protocol (BGP) to achieve various traffic engineering goals [4], yet, unfortunately there is no easy way to allocate resources from point A to point B between two arbitrary domains on the Internet. Both work...
