in this study, salmonella typhimurium bacteria removal from polluted water has been investigated using multiwall carbon nanotubes arrays. experimental results reveal that the contact time, the bacterial concentration and the weight of multiwall carbon nanotubes arrays have positive significant effects on the bacteria removal efficiency. increasing the contact time and the weight of multiwall ca...
Since MEG and EEG inverse problems are "illposed" (i.e., solutions cannot be uniquely determined), additional information such as fMRI and PET activation data can be used to impose additional constraints [1]-[6]. For example, fMRI data were used to fix the locations of equivalent current dipoles at activation areas [1][2][5] or to give higher weights for finding dipoles at activation areas [3][...
In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...
In this paper, we present the results of single-electron tunneling in two-dimensional (2D) hexagonal closed packed arrays of palladium nanoparticles. After inspecting the emergence of Coulomb blockade phenomena, we demonstrate the possibilities of using these arrays as a single-electron tunneling based hydrogen sensor. We assumed arrays of palladium nanoparticles with diameters of 3.5 and 6...
Lateral quantized charge transfer was observed with gold nanoparticle monolayers at the air/water interface. The electronic conductivity was measured by using an interdigitated arrays (IDA) electrode perpendicularly aligned at the air/water interface where a particle ensemble was trapped between the IDA fingers. The overall voltammetric responses were analogous to that of the Coulomb blockade w...
Multi-electrode arrays technology for the non-invasive recording of neural signals: a review article
The recording of electrophysiological activities of brain neurons in the last half-century has been considered as one of the effective tools for the development of neuroscience. One of the techniques for recording the activity of nerve cells is the multi-electrode arrays (MEAs). Microelectrode arrays (MEAs) are usually employed to record electrical signals from electrogenic cells like neurons o...
covering arrays of strength two have been widely studied as combinatorial models of software interaction test suites for pairwise testing. while numerous algorithmic techniques have been developed for the generation of covering arrays with few columns (factors), the construction of covering arrays with many factors and few tests by these techniques is problematic. random generation techniques c...
We investigate the structural and spectral properties of deterministic aperiodic arrays designed from statistically isotropic pinwheel tiling. By studying scaling cumulative integral its structure factor in combination with higher-order correlation analysis we conclude that belong to weakly hyperuniformity class. Moreover, by solving multiple scattering problem for electric point dipoles using ...
