Segmentation of LIDAR data has been repeatedly addressed by prior research in the photogrammetric community. The main motivations behind such research are to abstract the huge number of points in a typical LIDAR survey and to relate the LIDAR discrete points to physical objects. The key challenges for an effective and accurate segmentation of LIDAR data are: 1) defining meaningful neighborhoods...
Despite many scholars in various domains including scientific, academic, professional and political fields talking about “Islamic city” and “Islamic ideal city” (Utopia), there is not a specific definition for “Islamic city” based on sacred Islamic texts. In other words, a variety of definitions and attributes of the “Islamic ideal city” are spread in texts based on different backgrounds and st...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. banana fruit is one of important fruit. in this study some physical properties of banana fruit (cavendish variety) were determined. properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...

this paper presents a comparative study between three versions of adaptive neuro-fuzzy inference system (anfis) algorithms and a pseudo-forward equation (pfe) to characterize the north sea reservoir (f3 block) based on seismic data. according to the statistical studies, four attributes (energy, envelope, spectral decomposition and similarity) are known to be useful as fundamental attributes in ...
Precise estimation of the forest structural parameters supports decision makers for sustainable management of the forests. Moreover, timber volume estimation and consequently the economic value of a forest can be derived based on the structural parameter quantization. Mean age and height of the trees are two important parameters for estimating the productivity of the plantations. This research ...

With the increasing use of three-dimensional (3D) scanning tools and corresponding growth in the number and complexity of scanned objects or models, there is an increasing need in the development of robust and efficient processing techniques for scanned raw data, also referred to as point set surface and surface attributes. We present a features-preserving filtering algorithm for point set surf...
