In this paper, we propose a new geometric contour framework with support of specified vector field. First we define three criteria for selection of vector field in geometric model. According to the criteria, EdgeFlow, a powerful segmentation tool, is selected to generate desirable initial vector field. In order to overcome the drawbacks of conventional geometric models, multi-source external fo...

In this paper, we discuss approaches for blind source separation where we can use more sensors than the number of sources for a better performance. The discussion focuses mainly on reducing the dimension of mixed signals before applying independent component analysis. We compare two previously proposed methods. The first is based on principal component analysis, where noise reduction is achieve...

This work aims at a test-time fine-tune scheme to further improve the performance of an already-trained Denoising AutoEncoder (DAE) in the context of semi-supervised audio source separation. Although the state-of-the-art deep learning-based DAEs show sensible denoising performance when the nature of artifacts is known in advance, the scalability of an already-trained network to an unseen signal...

polyhydroxyalkanoates (phas) are bioplastics derived from renewable resources such as vegetable oils, corn starch, or microbes. the polyhydroxybutyrate (phb) is a short-chain-length pha, and the most important bioplastic produced by certain microorganisms in the presence of excess carbon sources. in this study batch cultivation of alcaligenes eutrophus with the aim of increasing phb production ...

Understanding the relationship between sink and source in maize is of prime importance in maize growing regions. In this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the College of Agriculture, Shiraz University, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of  SC704 maize hybrid.  A fa...

A reduction of a source distribution is a collection of smaller sized distributions that are collectively equivalent to the source distribution with respect to the property of decomposability. That is, an arbitrary language is decomposable with respect to the source distribution if and only if it is decomposable with respect to each smaller sized distribution (in the reduction). The notion of r...
