A spatial domain non linear filtering algorithm for the restoration of gray scale, and Color images that are corrupted by high density impulse noise is proposed. The proposed algorithm well suited for suppressing impulse and also Gaussian noises with different noise leves.It shows better results than the Standard Median Filter (MF), Trimmed Median Filter (TMF) and Weighted Median Filter. Experi...

Abstract— This Paper Presents Comparative Study of High Density Impulse Noise Removal method. Impulse noise is interference information pixels which result the black and white dots are spread distributed on the image. This type of noise can be caused by analog-to-digital converter errors, bit errors in transmission. Modified Mean-Median & ROM (MMM&R) filter that used to reduce impulse noise. Me...

2-Dimethyl amino ethyl azide (DMAZ) has attracted much attention as a suitable liquid fuel replacement for monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH) in propellant systems because, in contrast to these fuels, it is noncarcinogen. In this research, performance, and ignition delay time of DMAZ were studied with common liquid oxidizers such as inhibited red fuming n...

impulse buying is a significant aspect of consumer behavior and a critical concept in the marketplace. dramatic increases in consumption and possibility of credit buying all over the world has provided appropriate situations for impulse buying, however there is little information about impulse buying in eastern and in transition societies and economies. the purpose of this study is to develop a...

OBJECTIVE Impulse control disorders are commonly associated with dopaminergic therapy in Parkinson's disease (PD). PD patients with impulse control disorders demonstrate enhanced dopamine release to conditioned cues and a gambling task on [(11)C]raclopride positron emission tomography (PET) imaging and enhanced ventral striatal activity to reward on functional MRI. We compared PD patients with ...

Today, thanks to the rapid development of technology, importance digital images is increasing. However, sensor errors that may occur during acquisition, interruptions in transmission and storage cause noise degrades data quality. Salt pepper noise, a common impulse one most well-known types images. This negatively affects detailed analysis image. It very important pixels affected by are restore...

In this paper, we propose a method of designing an infinite impulse response (IIR) equalizer used to shape the readback signal to a partial response target in longitudinal and perpendicular recording channels. Based on the minimum mean-squared error (MMSE), the coefficients of the IIR equalizer are explicitly derived. For both recording channels, the proposed IIR equalizer performs better than ...

Abstract Commonly used 3D printed samples are partially infilled to reduce time and cost of printing, with mechanical properties dependent on the infill. In this work, influence percentage pattern infill in PLA elastic modulus characteristic stresses was analyzed. The modulus, E , ( σ 0.2 4 maximum tensile stress) were determined for each sample using impulse excitation technique, IET, uniaxial...
