The cellular network coverage in sparsely populated and mountainous areas is often patchy. That can be a significant impediment for services based on connections between vehicles and their environment. This article presents a method to reduce the waiting time occurring when a vehicle intends to send a message via a cellular network but is currently in a dead spot, i.e., an area without sufficient coverage. The authors introduce a data dissemination protocol that allows vehicles to connect through an ad-hoc network. The ad-hoc network peers can then find out which one will most likely leave the dead spot first. The selected vehicle stores then the messages of all connected vehicles and forwards them to the remote infrastructure as soon as it regains cellular network access. This research also discusses message flows in larger dead spots in which a vehicle may consecutively form several ad-hoc connections. Further, the authors describe an initial implementation of the protocol using the technology Wi-Fi Direct that is realized on most modern mobile phones.

Cyber physical systems open new ground in the automotive domain. Autonomous vehicles will try to adapt to the changing environment, and decentralized adaptation is a new type of issue that needs to be studied. This article investigates the effects of adaptive route planning when real-time online traffic information is exploited. Simulation results show that if the agents selfishly optimize their actions, then in some situations, the cyber physical system may fluctuate and sometimes the agents may be worse off with real-time data than without real-time data. The proposed solution to this problem is to use anticipatory techniques, where the future state of the environment is predicted from the intentions of the agents. This article concludes with this conjecture: if simultaneous decision-making is prevented, then intention-aware prediction can limit the fluctuation and help the cyber physical system converge to the Nash equilibrium, assuming that the incoming traffic can be predicted.

The user acceptance of technology determines its success and failure. Digital health is having a major impact on the improvement of health care and its delivery. My Health Record (MyHR) is the digital health solution that Australia implemented nationally to facilitate accessibility of health summaries data anywhere and anytime. The objective of this study is to explore the adoption of MyHR in general practices – one of the vital key players – in the state of Victoria. This article presents the current status of adoption in these general practices, using the lens of a proposed conceptual framework. This framework is based on a novel integrated model of user acceptance that merges three well-known user acceptance theories with some contextualisation to MyHR. It enables a comprehensive review of current system adoption, as well as factors such as the organisation, technology, people and perceived task fitness.

The focus of the current chapter is on humanoid robots as part of an inclusive education. It presents a brief overview of the main features of cyber physical systems which could be used as an advantage with children with special educational needs. Based on the specifics of the main types of special educational needs, a list of suggestions about the practical implications of educational robots to the classroom has been generated. A pilot study of the perception and attitude of children and teachers in a local Bulgarian school towards the application of cyber physical systems in education has been conducted. Based on previous research and the fundings of the pilot study, a few gaps of knowledge have been identified. First, the lack of empirical work on the application of technology to subjects, such as biology, chemistry, history, or to the development of social skills and creativity. Second, the scarce evidence of the long-term effects of interventions with children with special educational needs. Third, the lack of research on the attitudes of teachers with and without special educational needs children in the class towards educational robots. Last, but not least, the need for comparison of the perceptions and expectations of users of such technology across cultures.

Dynamic data management for multiprocessor systems in the absence of an operating system (OS) is a challenging area of research. OSs are typically used to abstract developers from the process of managing dynamic data at runtime. However, due to the many different types of multiprocessor available, an OS is not always available, making the management of dynamic data a difficult task. In this article, we present a hardware and software co-design methodology for the management of dynamic data in multiprocessor system on chips (MPSoC) development environments without an OS. We compare and contrast the method of sharing dynamic data between cores with standard methods and also to static data management methods and find that the proposed methodology can improve the performance of dynamic memory operations by up to 72.94% with negligible power and resource consumption.

The Internet of Things is seen as the progressive version of internet involving the transmission of information between things/objects with the aim of context-aware processing. The IoT can be anything ranging from home appliances, vehicles, almost anything networked and fitted with sensors, actuators or embedded computers. The IoT aims to make the internet sensory while maintaining a minimum quality of service (QoS) guarantee. In such an environment, job scheduling becomes very important, ensuring the minimum response time for message transfer. This work proposes an SCM based scheduling model for the IoT with the aim of minimization of the response time to optimize the scheduling performance of the underlying network and minimize the execution costs. After being serviced by a given node with its queue acting as a server for the message, appropriate next node for message forwarding is selected offering the least response time until the message reaches the destination. The effect of message scheduling to account for both the prioritized and non-prioritized message delivery has been studied.
