Removal of Blotches and Impulse Noise in Gray Scale Images Using Non-linear Algorithm
Abstract: An image consists of artifact, which appears in an image that is actually not present in the original imaged object. An image artifact (noise) is sometimes the result of improper operation of the imager, and other times a consequence of natural processes or properties of the human body. Blotches (bulk noise) and impulses are the artifacts where blotch can be either bright or dark spots and impulse can be salt …

Adaptive Selective Harmonic Elimination Method for Quasi Z-Source Cascaded Multilevel Inverters in Varying DC Voltage Condition
Abstract: AbstractIn this paper, a new control method for adaptive selective harmonic elimination in a quasi Z-source cascaded multilevel inverter (QZS-CMI) is proposed. According to real condition, the DC sources feeding the inverter are considered to be varying in time. In this condition, the switching angle and shoot-through duty ratio for each module are obtained off-line for different DC source values using particle swarm optimization (PSO) algorithm. The off-line data set …

Solar Energy Harvesting for Wireless Sensor Network Nodes
Abstract: A Wireless Sensor Network (WSN) consists of numerous sensor nodes that senses, processes and transmits sensor data from periphery of the network to BaseStation (BS) located at central location. A number of router nodes are deployed to transmit the sensed data to the BS. Generally, WSN nodes are battery powered. The lifetime of nodes is decided by the lifetime of the battery. To increase the lifetime of the batteries Energy …

An Efficient Secure and Security Authentication Scheme for Vehicular Ad-hoc Networks
Abstract: AbstractVehicular ad hoc networks (VANETs) are planned to be deployed within the next decennary to repair driver protection, stop clash, and provide traffic interpreter. Present years have supported an increasing interest in the security schemes for VANETs, as this territory was generally less investigated contrasted with different regions medium access and routing. In particular, efficient authentication of the messages in a VANET with other desirable security features has been heavily …

Pattern Reconfigurable Yagi-Uda Antenna
Abstract: This study proposes a prototype of a reconfigurable Yagi-Uda Antenna that is capable of reconfiguration of the radiation pattern. The proposed flexible antenna will work as the director, and reflector can be switched in a Yagi-Uda set up antenna by using a radio frequency PIN diode. The radiating signals can be directed at desired signals away from undesirable signals that are impinging on the antenna in opposite directions. The antenna …

Reliability-Aware Mathematical Model for Radiation-Hardened Satellite Communication Systems
Abstract: Satellite communication systems operate in radiation environments in which total ionizing dose (TID), displacement damage, and single-event effects (SEE) can progressively degrade electronic, optoelectronic, and communication components and can ultimately reduce link availability and mission reliability. This paper develops a Reliability-Aware Radiation-Hardened Satellite Communication Model (R-RHSCM) that mathematically couples the orbital radiation environment, accumulated radiation dose, component degradation, communication-link performance, single-event failure probability, redundancy, thermal effects, and adaptive mitigation. The …

A Review of Torque Ripple Reduction Techniques in Switched Reluctance Motors
Abstract: Switched Reluctance Motors (SRMs) have emerged as a promising alternative to conventional motor technologies due to their rugged structure, low manufacturing cost, high-temperature capability, and suitability for harsh environments. Despite these advantages, the widespread adoption of SRMs in applications such as electric vehicles, household appliances, industrial drives, and aerospace systems is significantly restricted by the issue of torque ripple. Torque ripple manifests as periodic fluctuations in the developed electromagnetic torque, …
