Decomposition of non-stationary signals such as electroencephalogram (EEG) and electrocardiogram (ECG) into stationary or quasi-stationary, signal segmentation, is a wellknown problem in many signal processing applications. Previous methods for segmenting a signal had problems such as slow speed, low performance, and several parameters which must be defined experimentally. In this paper a new m...

the present study aimed to evaluate the antimicrobial activity of a hetroalkyl oximec synthetic compoundderivative (benzophenone o-4-bromoethyl oxime) against two gram positive and three gram negative bacteria.the antibacterial characteristic of this compound was shown using the circular zone diameter of bacterial growthinhibition by disk-diffusion method. in addition, the random amplified poly...

the synthetic seed technology is becoming popular due to its wide application in germplasm conservation and for exchanges between countries in the floriculture trade. in this study, this method was used to study the germination and conversion capabilities of orchid species dendrobium white fairy when stored at different storage times and with different storage containers. a high germination per...

in this work application of seven synthetic polymers as adsorbents for the removal of hg(ii) from aqueous solution was studied. the equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and ph of the aqueous solution. variations of hg(ii) concentration in solution have been studied through measur...

This paper studies the problem of point cloud simplification by searching for a subset of the original input data set according to a specified data reduction ratio (desired number of points). The unique feature of the proposed approach is that it aims at minimizing the geometric deviation between the input and simplified data sets. The underlying simplification principle is based on clustering ...

This Letter presents a novel, computationally efficient interpolation method that has been optimised for use in electrocardiogram baseline drift removal. In the authors' previous Letter three isoelectric baseline points per heartbeat are detected, and here utilised as interpolation points. As an extension from linear interpolation, their algorithm segments the interpolation interval and utilise...

BACKGROUND One factor associated with poor outcomes in hemodialysis patients is exposure to a foreign membrane. Older membranes are very bioincompatible and increase complement activation, cause leukocytosis by activating circulating factors, which sequesters leukocytes in the lungs, and activates platelets. Recently, newer membranes have been developed that were designed to be more biocompatib...

Customer segmentation is a process that divides a business’s total customers into groups according to their diversity of purchasing behavior and characteristics. The data mining clustering technique can be used to accomplish this customer segmentation. This technique clusters the customers in such a way that the customers in one group behave similarly when compared to the customers in other gro...

due to the remarkable advantages of wavelet transformation, this technique is now very common in gravity analysis. in this research the green’s function occurring in the poisson potential field theory is used to construct non-orthogonal, non-compact, continuous wavelets. this kind of wavelet is directly corresponded to upward continuation procedure. simple geometrical forward models such as sph...

introduction: nasal teeth eruption is a rare phenomenon. the variability of symptoms and generic history makes the diagnosis difficult. this difficulty is more challenging when the tooth is placed in the depth of septum.   case report: our case is an example of this problem. herein, we present a case of intraseptal tooth with nasal obstruction and septal deviation and recurrent sinusitis. we pr...
