- Description: For the last quarter of a century understanding of the nature of telecommunication network traffic has been considered as an important research topic. Any well designed recovery strategy has to take into account the different resilience requirements of the single traffic flows in order to avoid excessive usage of bandwidth for standby links. Faced with multiple recovery options, an internet service provider (ISP) must decide which flows to protect to what extent against networks. Traditional techniques and models used to determine the availability and failure rates of telecommunications networks are based on classic failure models such as Mean-time between failure and Mean-time between service outage predictors. Network failures occur for many different reasons and occur in many different forms. These classic models only assume that the failure is caused by a hardware component of the network. With the widespread deployment of Internet technologies other factors that cause or contribute to failure in a telecommunications network must be explored. Two additional failure modes to existing published failure models, failure from Denial of Service attacks, and failures due to catastrophic events have been identified and defined along with an initial outline of a generalized prediction model based on Dynamic System Theory. Discussion is done on the effects of failures and survivability issues in network failures and how to overcome failures in IT based telecommunication network

- Description: We propose attributes that are needed in sophisticated agent teams capable of working to manage an evolving disaster. Such agent teams need to be dynamically formed and ca- pable of adaptive reorganization as the demands and com- plexity of the situation evolve. The agents need to have self- awareness of their own roles, responsibilities and capabilities and be aware of their relationships with others in the team. Each agent is not only empowered to act autonomously to- ward realizing their goals, agents are also able to negotiate to change roles as a situation changes, if reorganization is required or perceived to be in the team interest. The hierar- chical 'position' of an agent and the 'relationships' between agents govern the authority and obligations that an agent adopts. Such sophisticated agents might work in a collabora- tive team with people to self-organize and manage a critical incident such as a bush-¯re. We are planning to implement a team of agents to interface with a bush-¯re simulation, working with people in real time, to test our architecture.

- Description: The use of virtual worlds and video games offer exciting new avenues for the treatment of communication disorders and ongoing client support. But these new avenues need time to be envisaged, developed and rigorously evaluated. Also, perhaps the potential users themselves of such systems will need additional time to become comfortable and able to interact efficiently with them. Conceivably during this era of rapid technological advancements some basic virtual systems could be more swiftly introduced and trialled in order to complement existing therapy and support methods. A video-based simulation platform called Scenari-Aid fits this criterion. The aim of this study was to survey the perceptions of people who stutter who had used Scenari-Aid to assist them with their fluency and related anxieties. Could a simple, and relatively cheap to develop, simulation system have perceived benefits for a person who stutters and could these perceived benefits be translated beyond their practice environment? Over a six month period starting in late 2011, a 54 question online survey was made avail able to people who stutter and who were members of Speak Easy Australia and the McGuire Programme (Australia). To be eligible for the study you had to be over 18, have worked through a majority of the scenarios that were included in the Scenari-Aid application and have given the application more than one single attempt. It was assumed that most of the respondents would have been actively using a fluency shaping technique of some form during that time period. Questions were themed in terms of product quality, perceptions of fluency, value to therapy, effect on anxiety and product worth. Overall 37 completed responses were gathered and analysed using descriptive statistics. The results of this study were very encouraging in terms of the perceived effects that a simple simulation system could offer a person who stutters. Broadly speaking a majority of the users of Scenari-Aid found the system intuitive to use and understand. The most encouraging results stemmed from respondent's perception of their fluency and anxiety. Users indicated that by using this simple system that they felt their levels of fluency and speech confidence increasing. In terms of anxiety a majority of the users indicated that the system helped to ease anxieties related to speaking in public. Importantly though a majority of the users indicated that the system assisted them to better manage their speech and aided with self-critiquing speech progress. The results of this study indicate that there are perceived benefits for people who stutter to use video-based simulations to assist them with overall levels of fluency and social speaking confidence. The study also indicates that such a system could perhaps compliment conventional speech therapy and related support systems. More research is now required to investigate beyond user perceptions and to evaluate if indeed a simple video-based simulation system has real positive effects on rates of fluency, levels of anxiety and worth to conventional therapy techniques.

- Description: The emerging unmanned aerial vehicles (UAVs) pose a potential security threat for terrestrial communications when UAVs can be maliciously employed as UAV-eavesdroppers to wiretap confidential communications. To address such an aerial security threat, we present a friendly jamming scheme named terrestrial mobile jamming (TMJ) to protect terrestrial confidential communications from UAV eavesdropping. In our TMJ scheme, a jammer moving along the protection area can emit jamming signals toward the UAV-eavesdropper so as to reduce the eavesdropping risk. We evaluate the performance of our scheme by analyzing a secrecy-capacity maximization problem subject to the legitimate connectivity and eavesdropping probability. In addition, we investigate the optimized position for the jammer as well as its jamming power. Simulation results verify the effectiveness of the proposed scheme. © 2021 IEEE.

- Description: Causal loop diagrams (CLD) that emerged from systems thinking disciplines have been used to simulate complex inter-dependencies between causal factors in diverse phenomena. This paper highlights a process for generating a casual loop diagrams to represent the quality of electronic health record (EHR) ecosystem in a medical context. The quality inherent in the use of electronic health records for specific clinical purposes is taken to depend on factors including data integrity, reliability, relevance, timeliness and completeness. By improving the electronic health record ecosystem quality, health care providers can enhance their data sharing practices, and personalised patient care, while reducing the probabilities of medical errors. Ultimately the CLD can be used to run multiple simulations for several clinical case scenarios to understand the impact of various case phenomena on the quality of the electronic health record ecosystem. © 2023 ACM.
