this review paper provides researcherwith a comprehensive information about the carbon nano tubes and the catalyst parameters that influences theproduction and morphology of the of carbon nano tubes.carbon nanotubes, referred to as cnts, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. since discovery of cnts in 1991, many scienti...

The normal and lateral line cycloid scales of a cyprinid fish Rutilus frisii kutum Kamenskii, 1901 have been subjected to scanning electron microscopy technique to study their detailed structure. The scales have the general morphological characteristics of the cycloid scales. In the normal scale located below the dorsal fin, the focus lies on the anterior region with few mucous pores. There is ...

Determination of the type of precipitated calcium sulfate in mixing two incompatible injection and formation waters was studied experimentally in this work at two temperatures of 26oC and 80oC. Here the SEM, EDX and XRD techniques have been used to inspect the temperature effects on the morphology, type, and size of the precipitated calcium sulfate crystals. The result...

Anisotropic particles, with morphology from crescent to moon shape and size from micrometer to nanometer scale, are fabricated in batch scale with Janus emulsion as template. The strategy is also useful in the synthesis of Janus particles with chemically distinct hemispheres.

| EEcient implementation of morphological operations requires the decomposition of structuring elements into the dilation of smaller structuring elements. Zhuang and Haralick presented a search algorithm to nd optimal decompositions of structuring elements in binary morphology. In this paper we use the concepts of Top of a set and Umbra of a surface to extend this algorithm to nd an optimal dec...

The morphology of neurons and networks plays an important role in processing electrical and biochemical signals. Based on neuronal reconstructions, which are becoming abundantly available through databases such as NeuroMorpho.org, numerical simulations of Hodgkin-Huxley-type equations, coupled to biochemical models, can be performed in order to systematically investigate the influence of cellul...

Our ultimate long-term goal is to further the understanding of bed morphology and sediment dynamics under oscillatory flows. Experiments will be conducted to expand existing data sets of sand bed morphology and evolution in large scale laboratory facilities under controlled flow conditions. Based on this additional insight from the improved data set we aim to advance presently available tools f...

[1] Abyssal hills, which are pervasive landforms on the seafloor of the Earth’s oceans, represent a potential tectonic record of the history of mid‐ocean ridge spreading. However, the most detailed global maps of the seafloor, derived from the satellite altimetry‐based gravity field, cannot be used to deterministically characterize such small‐scale (<10 km) morphology. Nevertheless, the small‐s...

This paper presents the design and VLSI implementation of a new ASIC which performs in real-time the morphological operations of dilation and erosion. The ASIC's architecture is based on the extension of the majority-gate algorithm for morphological operations. The ASIC was implemented using a DLM, 0.7 ìm, CMOS, N-well process and it occupies a silicon area of 14.78mm2. Its maximum speed of ope...
