In Aviation sector, fatigue life and its analysis of each component is one of the prime factors of consideration due to the catastrophic failures that can result from it. Most of the components fail in high cycle fatigue regimes, but the compressor's fatigue life is intermediate between high cycle fatigue and low cycle fatigue. Objective of this paper is to estimate and compare the suitability of...
In this research paper, a rectangular fractal antenna is designed which may be used for IRNSS based smart city applications in India. For tracking and positioning applications, the government of India has developed its own navigation system which is called Indian Regional Navigational Satellite System (IRNSS). To design an antenna for such an application is desirable. For the upcoming smart cities...
In this paper, a simple self similar multi fractal cantor antenna is designed for IRNSS and GAGAN applications in India. A new navigational system which is developed and controlled by Indian government is called Indian Regional Navigational satellite system (IRNSS). IRNSS simply replaces the role of Global Positioning System in India by which, it provides integrity, availability, continuity and selectivity...
In this letter, a simple microstrip patch antenna is designed for Wireless Local Area Network (WLAN) applications in IEEE 802.11b/g/n are presented. WLAN is most commonly used wireless distribution standard for short distance network communication. This paper describes a high-gain; single band microstrip antenna is printed on FR-4 substrate and has dimensions of 29.2 × 29.2 × 1.6mm3 with a ground...
This paper presents the design and implementation of a miniaturized dual band hybrid operating at two arbitrary frequencies. The hybrid is realised by adding quarter wavelength stubs to the conventional single section hybrid. The folded stub approach is used to miniaturize the size of this hybrid. The hybrid was designed and fabricated for S and C band with centre frequencies at 2.35 GHz and 4.6 GHz...
In this paper, we present a bandwidth-efficient data reliability mechanism for Smart Grid Wide-Area Monitoring communication networks. Reliable transmission of data pack-ets, especially feedback control packets, is deemed a critical requirement. By sending multiple copies of data packets on node or edge disjoint paths, reliability can be achieved. However, this is inefficient in terms of bandwidth...
In this paper, we present efficient data reliability mechanisms for a communication network supporting wide area monitoring applications in the electrical Smart Grid. Reliability of data packets, especially control packets, is deemed a critical requirement. Reliability can be achieved by sending multiple copies of the data packet on disjoint paths. However, this is inefficient in terms of bandwidth...
The future of the electrical power grid is the “Smart Grid” that uses a combination of digital sensing and actuation technologies. For example, Phasor Measurement Units (PMU) can be used to accurately measure the quality of power and help improve the reliability and efficiency of the grid. A specially designed network architecture is required to transport the PMU data to the data processing systems...
Scarcity of energy resources, increasing power generation cost and ever-growing demand for electric energy necessitates optimal economic dispatch in today's power systems. The main objective of economic dispatch is to reduce the total power generation cost, while satisfying various equality and inequality constraints. Traditionally in economic dispatch problems, the cost function for generating units...
