There has been much recent work on machine learning based approaches for cognitive task scheduling in multifunction radar (MFR). However, the available MFR scheduling approaches rely on knowledge of the operating environment; in practice, though, the inherent uncertainty with dynamic radar environments poses significant challenges, especially for c...

Cognitive radars sense, interact with, and learn from the environment continuously. This paradigm can be applied to a multifunction radar (MFR), which performs multiple functions, such as surveillance, tracking, and communications amongst others. To execute these tasks, a radar resource management (RRM) module assigns the available resources to the...

A multi‐function radar is designed to perform disparate functions, such as surveillance, tracking, fire control, amongst others, within a limited resource (time, frequency, and energy) budget. A radar resource management (RRM) module within a radar system makes decisions on prioritisation, parameter selection, and scheduling of associated tasks. Ho...

In this paper, performance evaluation and technical audit of a 747 MW thermal power plant consisting of three generating units is conducted. The factors influencing the performance of the plant have been identified and improvements in processes and mechanical, electrical, instrumentation, and safety engineering are suggested. These improvements wou...

Full duplex (FD) communication has emerged as an attractive solution for increasing the network throughput, by allowing downlink (DL) and uplink (UL) transmissions in the same spectrum. However, only employing FD base stations in heterogeneous cellular networks (HCNs) cause coverage reduction, due to the DL and UL interferences as well as the resid...

In this paper, we develop a tractable model for joint downlink (DL) and uplink (UL) transmission of K-tier heterogeneous cellular networks (HCNs) with simultaneous wireless information and power transfer (SWIPT) for efficient spectrum and energy utilization. In the DL, the mobile users (MUs) with power splitting receiver architecture decode informa...

The emerging fifth-generation (5G) wireless communication system is expected to provide higher capacity, seamless connectivity and energy control to serve growing energy intensive multimedia applications. Simultaneous wireless information and power transfer (SWIPT) in heterogeneous cellular networks (HCNs) has the great scope in the 5G offering eff...

This paper describes the design and implementation of a portable, inexpensive and cost effective spectrophotometer. The device combines the use of compact disc (CD) media as diffraction grid and 60 watt bulb as a light source. Moreover it employs a moving slit along with stepper motor for obtaining a monochromatic light, photocell with spectral sen...
