Title: Novel Fiber Sensing System
Abstract: Optical fiber-based devices have been widely deployed in recent years. There are many advantages of using fiber as a sensor. These include electrically-passive operation, light weight, immunity to radio frequency interference and electromagnetic interference, high sensitivity, compact size, corrosion resistance, easily multiplexing and potentially low cost. Several novel fiber-based sensors and technologies developed are presented here, including fiber Bragg grating (FBG) based sensors, photonic crystal fiber (PCF) based sensors, specialty fiber-based sensors and distributed fiber sensing systems. FBGs as instinctive sensors, are ingeniously designed as two-dimensional (2D) tilt sensors, displacement sensors, accelerometers and corrosion sensors here; PCF based evanescent field absorption sensor, PCF induced Mach-Zehnder interferometer and Fabry-Perot refractometer for temperature and refractive index sensing are presented; based on localized surface Plasmon resonant (LSPR) effect, nano-sized fiber tip with gold nanoparticles are demonstrated for live cell index bio-sensing applications.

Speech Title: Systems Thinking and Modern Modeling Methods in Developing Complex, Dynamic, and Adaptive Systems
Abstract: Modern-day systems are evolving and becoming more complex and interdependent as time progresses. Many contemporary systems are dynamic, adaptive, and may have emergent behavioral properties that are unexpected and can drastically affect system performance over the system’s lifetime. We address foundational systems thinking concepts such as Distinguished Systems Relationships, and Perspectives (DSRP), Vision, Mission, Culture, Learning (VMCL), Systems Architecting, and Holistic Thinking. We illustrate the connections between Systems Thinking and modern Enterprise and Systems Engineering principles, methods, and techniques such as Enterprise Architecture Methods, Object-Oriented Systems Engineering Methods (OOSEm), Decision Engineering, document and Model Based Systems Engineering (MBSE) methods and tools, and the use of Systems Modeling Language (SYSML) and Unified Modeling Language (UML). We discuss the application of Systems Thinking to the design and development of large, complex, dynamic, and adaptive systems and emphasize complex, systems design methods and issues such as wicked problems, emergent behaviors, and predictive behavior. We use Unmanned Aerial Vehicle systems, optical systems, and infrasound systems as examples.

Speech Title: 5G Wireless Communications and Networking
Abstract: The vision of next generation 5G wireless communications lies in providing very high data rates, extremely low latency, manifold increase in base station capacity, and significant improvement in users' perceived quality of service (QoS), compared to current 4G LTE networks. Ever increasing proliferation of smart devices, introduction of new emerging multimedia applications, together with an exponential rise in wireless data demand and usage is already creating a significant burden on existing cellular networks. 5G wireless systems, with improved data rates, capacity, latency, and QoS are expected to be able to overcome most of the current cellular networks' problems. In this speech, I will make an exhaustive review of wireless evolution toward 5G networks. I will first discuss the new architectural changes associated with the radio access network (RAN) design including air interfaces, smart antennas, cloud and heterogeneous RAN. Subsequently, I will briefly introduce underlying novel mm-wave physical layer technologies, encompassing new channel model estimation, directional antenna design, beamforming algorithms, and massive MIMO technologies. Then, the details of MAC layer protocols and multiplexing schemes needed to efficiently support this new physical layer are discussed.

Speech Title: Carrier phase estimation and nonlinearity compensation in optical communication systems using advanced modulation formats
.Abstract: Over 95% of digital data transmitted are carried by optical fibres, to form the great part of national and international communication infrastructure. Achievable information rates are natural figures of merit in coded communication systems to demonstrate the net data rates achieved by soft-decision decoding. Currently, achievable information rates of optical communication systems are limited by linear and nonlinear transmission impairments in the links. Although chromatic dispersion and polarization mode dispersion can be fully compensated using digital equalizers, additional distortions of equalization enhanced phase noise will be introduced due to the interactions between digital dispersion equalizers and laser phase noise. Also, with the increment of optical launch power the performance of communication systems will be significantly degraded by nonlinear distortions due to the fibre Kerr effect. The distortions from equalization enhanced phase noise and fibre nonlinearities are more severe for systems with larger transmission bandwidths, closer channel spacing, higher-order modulation formats and longer transmission distances. In this work, the efficacy of carrier phase estimation and nonlinearity compensation for enhancing achievable information rates in optical communication systems have been investigated, when different scenarios of system bandwidth, modulation format and transmission distance were applied.
Key Words: Optical fibre communication, achievable information rate, equalization enhanced phase noise, fibre nonlinear effects, carrier phase estimation, nonlinearity compensation
