Image fusion is finding its application in all spheres of life like medical, military, geological etc. The aim of Image fusion is to combine the information of same scene images taken from different sensors or the images with focus on different objects. Fused image is more informative and better in quality. In this paper, a hybrid technique is developed and carried out a detailed comparative analysis with the existing techniques based on RGB contents, Entropy of the image. This paper is based on considering the remote sensing application General TermsImage fusion, PCA, Wavelet Transforms, Hybrid Technique.

Apart from aerosols, contaminated surfaces with SARS-CoV-2 virus are the significant carriers of virus transmission. The disinfection and sanitization of the indoor and outdoor places are one among the powerful and effective strategies to avoid the surface-to-human transmission of SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) through frequent touch and physical contact. Electrostatic spraying is one of the effective and efficient methods to apply the liquid-based sprays on surfaces to be disinfected or sanitized. This technique covers the directly exposed and obscured surfaces uniformly and reaches to hidden areas of the target. In this paper, the design and performance parameters of a motorized pressure-nozzle based handheld electrostatic disinfection device were optimized and the chargeability of ethanol (C2H5OH), formaldehyde (CH2O), glutaraldehyde (C5H8O2), hydrogen peroxide (H2O2), phenol (C6H5OH) and sodium hypochlorite (NaClO) has been critically investigated. The chargeability indicator for disinfectants was presented in terms of the charge-to-mass ratio. The significant value of the charge-to-mass ratio of 1.82 mC/kg was achieved at an applied voltage of 2.0 kV, the liquid flow rate and pressure of 28 ml/min and 5 MPa, respectively. The experimental results are well aligned to the proposed theoretical context.

Modern avionics provide a comprehensive human-machine interaction. The modern electronic displays are the key components of any glass cockpit based aircraft employing the state of art avionics and are being increasingly used due to two main reasons: firstly, the continuous advancements and improvements in the electronic display technologies, and second being the progressive changes in the onboard data distributing and processing methods in both military and civil aircraft. In this article we have discussed several electronic display devices and relevant technologies for avionics display use especially with reference to the head-up displays. These display technologies have been analysed with reference to the avionics display requirements and vital parameters like
