Abstract
Catastrophic events such as hurricanes, flash floods and earthquakes in recent years have become a major threat to the whole world. It not only causes losses in economic and human life, it also led to significant damage to the critical infrastructures, mainly electrical supply systems. Failure in this system disrupts the functionality of many other critical infrastructures such as healthcare, banking, water supply and national security. Realising the importance of electricity supply system, remarkable efforts are made by power utilities and researchers to achieve a resilient electrical supply system. The aim is to ensure the system can resist the sudden changes and quickly recover after the occurrence of catastrophic events so that electricity can be supplied as maximum as possible. Distribution system has a great potential for resiliency improvement in a power system. This talk will discuss the concept of power system resilience and research opportunities to improve the resiliency of a distribution system. Overview of the current climate conditions that lead to catastrophic events will also be presented to show the needs of a resilience power system.

Abstract
It is an indisputable fact that the proportional-integral-derivative, PID, controller has been, and it still is, the workhorse of control at process industries. Even if more advanced control solutions are permeating into the control rooms, the PID continues to be the preferred solution at field level. Therefore, the reliability of those advanced, plant-level solutions, depends on the appropriate performance of such PID level. One of the cornerstones of activity in PID control is that of adjusting the PID gains: tuning the PID controller. Being this a basic need in control practice, the goal of obtaining simple, powerful and as generalist as possible tuning rules has been one of the major drivers of research for improvements on PID control.
In this lecture attention is focused on model-based tuning of single-loop PID controllers in terms of the robustness/performance and servo/regulator trade-offs. Although the robustness/performance compromise is commonly considered, it is not so common to also take into account, for example, the conflict between input and output disturbances, referred also as the servo/regulator trade-off. As interested in providing a unified tuning approach, it is shown how the proposed methodology allows to deal with different process dynamics in a unified way. The proposed approach to design is completely analytical and motivated by the solution to a conveniently stated H-inf problem.

Abstract
Ambipolarity has become important for many applications in recent years. In addition to device fabrication from materials with ambipolar behavior, many factors such as the controllability of ambipolarity and the degree of ambipolarity have attracted the attention of researchers. Many factors causing ambipolarity have been reported in the literature. Especially, 2D dicalgonites such as WS2 and MoS2 are the leading materials for FET devices with ambipolar behavior. Besides the properties of these 2D materials, the geometry of the device also has an effect on ambipolarity. In this study, the effect of geometric properties of the FET device, such as channel width, on ambipolarity was investigated. For the FET device, it was seen that the instability starts from a few layers of channel thickness and then decreases again as the thickness increases. It was observed that as the thickness increased, the degree of ambipolarity approached zero. The degree of ambipolarity approaching zero indicates that the WS2 channel exhibits natural n-type behavior and the ambipolar effect disappears.

Abstract
The vehicle sector has seen significant changes with the Intelligent Transportation System (ITS) over the last decade. New technologies are being integrated into vehicles to detect possible road hazards and enhance the driving experience. In today’s digital world, ITS plays a critical role in modern life mobility as vehicle connectivity grows. An important component is being integrated into cars is that communication technologies to establish vehicle connectivity. VANETs (Vehicular Ad-hoc Networks) are intelligent transportation system that enable vehicles to communicate each other directly through a wireless network. Each vehicle acts like node and equipped with transceiver to send and receive data. Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications are the two types of VANETs. In V2V communication, every vehicle exchanges traffic-related information to reduce traffic congestion, increase passenger safety, and enable efficient vehicle management. In V2I communication, on the other hand, the communication is between vehicles and wireless access points to make an early informed decision to the situation that could cause untoward incidents.
The focus of this talk is on 5G and its expected usage on Vehicle Communication. In this context, recent research developments that must be provided to allow a safe communication in Vehicle communication are discussed.
Recent research developments in VANETs consist of traffic management, road safety and infotainment applications. Road safety applications are designed to provide information to drivers about different possible risks such as collision avoidance (safe distance), road sign notifications (curve speed warning), incident management (emergency vehicle warning). Traffic management applications designed to improve road traffic management that make the users awere of local traffic information such as speed management and vehicle tracking. Traffic management and road safety applications are more of V2V interest. As for infotainment applications, these applications help provide internet access to the vehicles such as finding the nearby gas station or parking booking. Recently, studies for V2V communication are popular. Research and testing of communication technologies used in the VANETs environment is gaining attention. Reliable information exchange between vehicles depends on using V2V communication technology. Dedicated Short‑Range Communication (DSRC), Wireless Access in Vehicular Environments (WAVE) and Cellular Systems are types of communication technology in VANETs. An alternative solution for V2V communication technology is cellular systems. Cellular Systems covers the technologies that is already in use for V2V communications such as Long-Term Evolution (LTE) or Fifth Generation (5G) technologies. Different communities, such as the 5G Automotive Association (5GAA) and the Third Generation Partnership Project, are supporting the Cellular Systems. Each of communication technologies have their own set of advantages. For example, DSRC is effective for a short-range application (about 300 m) such as collision avoidance and other security applications, but Cellular Systems are better for applications that require longer coverage ranges.
