assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Fragmentation measurement using image processing
In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...
متن کاملAssessment Effect of the Spatial Resolution of Digital Elevation Model on Daily Discharge Estimation of Arazkuseh Watershed Using SWAT Model
The spatial quality of the Digital Elevation Model (DEM) has a great effect on the Soil and Water Assessment Tool (SWAT) semi-distributed model. The purpose of this study was to evaluate the effect of spatial accuracy of three DEMs with spatial resolutions of 10, 50 and 200 m on the results of daily discharge simulation in the Arazkuseh subwatershed located in Gorganroud watershed, Golestan pro...
متن کاملSpatial Resolution Properties of Penalized-Likelihood Image Reconstruction: Space-Invariant Tomograp - Image Processing, IEEE Transactions on
This paper examines the spatial resolution properties of penalized-likelihood image reconstruction methods by analyzing the local impulse response. The analysis shows that standard regularization penalties induce space-variant local impulse response functions, even for space-invariant tomographic systems. Paradoxically, for emission image reconstruction, the local resolution is generally poores...
متن کاملTraffic Spatial Measurements Using Video Image Processing
In certain conditions, images of a traffic scene give to the traffic engineer a lot of valuable informations. Due to its efficiency and flexibility video image analysis can be used in the three main domains of traffic management, that is measuring, monitoring and control. Moreover, this technique permits spatial measurements not available by classical means. Finally, portability, and ease of in...
