for planting fine seeds in cellular trays, an automatic pneumatic seeder was designed, constructed and evaluated. catia software was used to design and analysis the system parts of the seeder. different parts of the seeder, including vibrating seed hopper, vacuum boom, seed picking nozzles, seed tube, pneumatic system and electronic control unit for automation of the seeder, were designed and c...

The seed for this collaborative project has been the Land-Ocean Interaction in the Coastal Zone [LOICZ] typology group: a loosely organized set of researchers examining and estimating fluxes in basic nutrients in the coastal zone [1] This prior work has resulted in a well-defined process and a set of stand-alone and web-based tools for automatic typology development with geospatial data sets [3...

In this paper, we present a semi-automatic region growing algorithm to segment the intrathoracic airway tree from 3-d CT images. A common problem with region growing is leakage. In order to limit leakage, our method bounds the segmentation using cylinders of adaptive orientation and dimensions. The leaks are detected based on anatomical information of the airways and an algorithm to avoid them ...

In this paper, we propose a novel tubular structure segmentation method, which is based on an intensity-based tensor that fits to a vessel. Our model is initialized with a single seed point and it is capable of capturing whole vessel tree by an automatic branch detection algorithm. The centerline of the vessel as well as its thickness is extracted. We demonstrated the performance of our algorit...

Tasks such as classification of data and determining the groundstate a Hamiltonian cannot be carried out through purely unitary quantum evolution. Instead, inherent non-unitarity measurement process must harnessed. Post-selection its extensions provide way to do this. However they make inefficient use time resources -- typical computation might require $O(2^m)$ measurements over $m$ qubits reac...

We present an accuracy evaluation of a semi-automatic registration technique for 3D volume reconstruction from fluorescent confocal laser scanning microscope (CLSM) imagery. The presented semi-automatic method is designed based on our observations that (a) an accurate point selection is much harder than an accurate region (segment) selection for a human, (b) a centroid selection of any region i...
