Joule heating and negative dielectrophoresis, caused by AC electric fields in a microchannel, have been employed for cloud point extraction of phospholipid as a model of membrane-associated biomolecules.

spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. this review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. the use of an appropriate sample handling technique is a...

Spectrometric techniques for the analysis of trace cadmium have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, such as electrochemical deposition, precipitation, coprecipitation, solid phase extraction, liquid-liquid extraction (LLE) and cloud point...

Nose tip detection is an essential point in 3d face alignment, pose estimation and the discrimination process. A method to determine nose tip location based on exploiting local descriptors(shape index) from each point cloud on the 3d surface mesh is presented in this paper. Furthermore, theeffective energy constraint was appliedover each 3d mesh data point. Then NN-Nearest Neighbour classificat...

LIght Detection And Ranging (LIDAR) for terrain and land surveying has contributed to many environmental, engineering and civil applications. However, the analysis of Digital Surface Models (DSMs) from complex LIDAR data is still challenging especially for highly sloped landscapes. Commonly, the first task to investigate LIDAR data point clouds is to separate ground and object points as a prepa...

Laser scanning data has been an important raw source for building model extraction. However, the automatic reconstruction of building model is still a problem. Roof plane Extraction from point cloud is a key step to building reconstruction, which can be easily affected by the noise existed in laser scanning data. It is often difficult to determine which plane a point should belong to when the p...

Mobile terrestrial laser scanners (MTLS) produce huge 3D point clouds describing the terrestrial surface, from which objects like different street furniture can be generated. Extraction and modelling of the street curb and the street floor from MTLS point clouds is important for many applications such as right-of-way asset inventory, road maintenance and city planning. The proposed pipeline for...

in this study, the trace amounts of erythrosine, as a food dye is determined by cloud point extraction-scanometry (cpe-scanometry) as a new, facile, available, fast, sensitive, and low cost method. the method is based on the cpe of analyte from aqueous solution, diluting the extracted surfactant-rich phase with ethanol, transfer to plexiglas®cell and scanning the cells containing the analyte so...

A new algorithm for deriving skeletons and segmentations from point cloud data in O(n) time is explained in this publication. This skeleton is represented as a graph, which can be embedded into the point cloud. The CAMPINO method, (C)ollapsing (A)nd (M)erging (P)rocedures (IN) (O)ctree-graphs, is based on cycle elimination in a graph as derived from an octree based space division procedure. The...
