A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications (2013)
Presentation / Conference Contribution
Zolfaghari, M., Riley, N. G., Mahdawi, M., & Shen, J. (2013, November). A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications. Presented at 2013 Loughborough Antennas and Propagation Conference, LAPC 2013

The paper presents a co-planar wave guide (CPW)-fed slot loaded low return loss planar printed antenna with a small size designed for wireless communication and UWB applications. First, a conventional UWB antenna is modeled to provide a reference poi... Read More about A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications.

Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio (2013)
Presentation / Conference Contribution
Mehdawi, M. A., Riley, N. G., Ammar, M., Fanan, A., & Zolfaghari, M. (2013, November). Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio. Presented at 2013 21st Telecommunications Forum Telfor, TELFOR 2013 - Proceedings of Papers

Cognitive radio offers an increasingly attractive solution to overcome the underutilization problem. A sensor network based cooperative wideband spectrum sensing is proposed in this paper. The purpose of the sensor network is to determine the frequen... Read More about Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio.

Active fault tolerant control for nonlinear systems with simultaneous actuator and sensor faults (2013)
Journal Article
Sami, M., & Patton, R. J. (2013). Active fault tolerant control for nonlinear systems with simultaneous actuator and sensor faults. International journal of control, automation and systems, 11(6), 1149-1161. https://doi.org/10.1007/s12555-013-0227-1

The goal of this paper is to describe a novel fault tolerant tracking control (FTTC) strategy based on robust fault estimation and compensation of simultaneous actuator and sensor faults. Within the framework of fault tolerant control (FTC) the chall... Read More about Active fault tolerant control for nonlinear systems with simultaneous actuator and sensor faults.

An ultrasonic transducer transient compensator design based on a simplified Variable Structure Control algorithm (2013)
Journal Article
Ma, S., Wilkinson, A. J., & Paulson, K. S. (2014). An ultrasonic transducer transient compensator design based on a simplified Variable Structure Control algorithm. Ultrasonics, 54(2), 502-515. https://doi.org/10.1016/j.ultras.2013.07.017

A non-linear control method, known as Variable Structure Control (VSC), is employed to reduce the duration of ultrasonic (US) transducer transients. A physically realizable system using a simplified form of the VSC algorithm is proposed for standard...
