Although gratings beyond the Nyquist limit of the peripheral retina are visible as aliased percepts when presented in isolation, the reported lack of aliasing for targets with complex spectra (edges, lines, letters) suggests that aliased frequency components are invisible in the presence of sub-Nyquist image components. We tested this hypothesis by systematically exploring a range of stimulus p...

Supply chains are constantly exposed to various risks. An incident or uncertain event, which has positive or negative effect on the objectives of a project, is called a risk. According to this identification, analysis and prioritization of risks may have a significant role in the success of the project. The purpose of risk management is to reduce the risks of non-achievement of these object...

general, any n-sequence determines a multiset of (= n!/k!(n-k)!) k-sequences. "J Suppose, conversely, that we are given a multiset 01 k-sequences. Does that multiset come from some sequence? If so, is the source sequence unique? Such questions are reminiscent of the problem of reconstructing graphs from vertex-deleted sub raphs, which has received a great deal of attention in the last twent yea...

The paper deals with a new technique of fragile image watermarking. Proposed technique exploits inter-subband dependencies in order to minimize the influence of inserted watermark on the host image quality. Using the unique watermark based on the low-frequency subband, proposed scheme is resistant against attacks based on series of images analysis. Tampering detection ability of the proposed te...

Background and objectives: Menthol and menthone are two important components in the essential oil of peppermint(Mentha piperita L.) which are commercially used in the pharmaceutical industries. This study has presented the allometric ratio of menthol and menthone to pulegone affected by the induction of bioregulators. Methods: The experiment w...

In this paper a novel approach for energy disaggregation is introduced that identifies additive sub-components of the power signal in an unsupervised way from high-frequency measurements of current. In a subsequent step, these sub-components are combined to create appliance power traces. Once the subcomponents that constitute an appliance are identified, energy disaggregation can be viewed as n...

Traditional network abstractions follow a layered model in which a sub-system interacts with other network components through very narrow interfaces. We content that this model is weak both in providing clear models of end-to-end properties and allowing adaptation to the more abstract properties of systems. We propose instead a graphcentric, contextual abstract model in which sub-systems can re...

to study the effects of zabol wastewater treated with two kinds of fertilizer (manure and chemical fertilizer) application vs use of ordinary water on grain yield and yield components in corn (kosc704) a field experiment was conducted at the university of zabol, iran during 2007 growing season. the statistical plan selected was a split plot one of three replications. the treatments were compris...
