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 کاملFour-dimensional dynamic flow measurement by holographic particle image velocimetry.
The ultimate goal of holographic particle image velocimetry (HPIV) is to provide space- and time-resolved measurement of complex flows. Recent new understanding of holographic imaging of small particles, pertaining to intrinsic aberration and noise in particular, has enabled us to elucidate fundamental issues in HPIV and implement a new HPIV system. This system is based on our previously report...
متن کاملPrimary Particle Size Distribution Measurement of Nanomaterials by Using TEM
Industrial applications of nano-particles are reported in many fields recently. Regulation of nano-materials is also discussed in Organization for Economic Co-operation and Development (OECD). European Union (EU) announced the definition of nano-material in 2012. According to EU definition, nanomaterial means a natural, incidental or manufactured material containing particles, in an unbound sta...
متن کاملStatus of two-dimensional ion velocity measurement system in NSTX
A two-dimensional ion velocity measurement system is being developed under a US-JAPAN collaborative activity. The diagnostic is used to determine Doppler shifts from the intensity ratio of a visible line from the same light source, measured with two interference filters that have different transmission pass bands. A fast visible camera is used as two-dimensional detector. The system was tested ...
متن کاملField Measurement of Particle Settling Velocity
Many stormwater management practices depend on sedimentation as their primary removal mechanism, but the settling velocity distribution of particles in runoff from a specific watershed is rarely known. A simple and effective method to characterize settling velocity distribution is needed to improve the design of stormwater management practices. Elutriation devices have been used to characterize...
