restructuring the recent developments in the power system and problems arising from construction as well as the maintenance of large power plants lead to increase in using the distributed generation (dg) resources. dg units due to its specifications, technology and location network connectivity can improve system and load point reliability indices. in this paper, the allocation and sizing of di...

To tackle the challenge in artificial spinal disc (ASD) design of restoring mechanics a natural disc, this study proposes an innovative lattice-based ASD for reproducing patient-specific anisotropic rotational response, inspired by freedom provided lattice structures. Motivated great potential machine learning to improve computational processes, method is proposed computationally efficient topo...

Structure description and matching are useful techniques with wide area of applications. Common motivation could be the need for object identification. This work presents a specific method developed to describe and match particular type of structures – sets of points in two-dimensional space. The method incorporates creation of the structure description suitable for further matching and a proce...

Since solar, wind and tidal energies mainly depend upon statistical parameters with respect to changing climate and environment, focus on hybrid generation system design increases the availability of the power generation system. The hybrid system also reduces the dependence on one environment parameter thus providing the consumer with reliable and cheap electricity. Therefore optimal combinatio...

Floating bead filters (FBFs) are expandable granular filters that display a bioclarification behavior similar to sand filters. They function as a physical filtration device (or clarifier) by removing solids, while simultaneously encouraging the growth of bacteria that remove dissolved wastes from the water through biofiltration processes. Presently, there are two classes of FBFs that exist. Hyd...

A NIR method was developed for the on-line monitoring of alkali-free cloth/phenolic resin prepreg during its manufacturing process. First, the sizing content of the alkali-free cloth was analyzed, and then the resin, soluble resin and volatiles content of the prepreg was analyzed simultaneously using the FT-NIR spectrometer. Partial least square (PLS) regression was used to develop the calibrat...
