چکیده
In [4], given a binary 26-adjacency voxel-based digital volume V , the homological information (that related to n-dimensional holes: connected components, ”tunnels” and cavities) is extracted from a linear map (called homology gradient vector field) acting on a polyhedral cell complex P (V ) homologically equivalent to V . We develop here an alternative way for constructing P (V ) based on homological algebra arguments as well as a new more efficient algorithm for computing a homology gradient vector field based on the contractibility of the maximal

Effects of Digital Elevation Model (DEM) Spatial Resolution on the Recognition of Physiography Characteristics of the Basin )A Case Study of Shahrchai Watershed)
In recent years with developing geographic information systems tools, modeling and simulating methods has been developed quickly. Availability of accurate base maps is the basis of the cell sizes determination and preparing digital hydrologic models. Removing errors and minimizing of uncertainty factors in the digital models play the main role in improving the accuracy of the maps. The main pur...
متن کاملComparison of the Efficacy of Digital Caliper and a Newly Designed Digital Bone Gauge for Measurement of Edentulous Alveolar Ridge Width
Objectives: An efficient, safe, affordable and easily accessible measuring instrument for quantitative assessment of bone prior to dental implant placement enables more accurate treatment planning. Costly imaging modalities are neither widely available, nor affordable for some patients. This study sought to assess the efficacy of a newly designed digital bone gauge for measurement of bone width...

متن کامل"Technical Report" Flood Hydrograph Simulation Using HEC-HMS Model in Sarbaz River Basin of Sistan and Baluchestan Province
Hydrological models are simplified representation of the real basin system, which helps to assess basin function in response to different inputs and better understanding of hydrological processes. The HEC-HMS model is one of the most important hydrological models for Flood estimating volumes and discharge in watersheds. In this research, the HEC-HMS hydrologic model was used to simulate the ...
متن کاملBackground-Based Delineation of Internal Tumor Volumes on Static Positron Emission Tomography in a Phantom Study
Objective(s): Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. Methods: Three hollow models were filled with 55.0 kBq/mL fluorine18- fluorodeoxyglucose (18F-FDG) to represent tumors. The models were fixed to a barrel filled w...
