Wearable Flexible Sensors: A Review

Abstract: This paper provides a review on some of the significant research work done on wearable flexible sensors (WFSs). Sensors fabricated with the flexible materials have been attached to a person along with the embedded system to monitor a parameter and transfer the significant data to the monitoring unit for the further analyses. The use of wearable sensors has played a quite important role to monitor the physiological parameters of a person to minimize any malfunctioning happening in the body. This paper categorizes the work according to the materials used for designing the system, the network protocols, and different types of activities that were being monitored. The challenges faced by the current sensing systems and future opportunities for the WFSs regarding its market values are also briefly explained in this paper.

A cognitive behavioral model of social anxiety disorder: update and extension

Abstract: Publisher Summary This chapter focuses on the original 1997 cognitive behavioral model for social anxiety disorder (SAD), which delineates the processes by which SAIs are affected by their fear of negative evaluation in potentially social-evaluative situations. The original model has provided a solid framework for understanding the factors that comprise and maintain SAD. Since the publication of Rapee and Heimberg (1997), updates are provided in the form of reviews of the literature that support various aspects of the model, applied the model to a case study of a person with SAD, and conducted a comparison between the model and the very influential and productive model proposed by Clark and Wells. Given that there has been over a decade of intervening research, however, there are areas in the model that warrant expansion, as well as additional factors that necessitate inclusion in the model. The chapter presents a revised cognitive behavioral model of SAD and the research supporting these modifications. The chapter's primary focus are five areas: the important role of imagery (and imagery perspective), PEP, the combined cognitive biases hypothesis, fear of positive evaluation (FPE), and the potential role of difficulties in the regulation of emotional responses, including but not limited to anxiety.

Augmented Reality in education – cases, places and potentials

Abstract: Augmented Reality is poised to profoundly transform Education as we know it. The capacity to overlay rich media onto the real world for viewing through web-enabled devices such as phones and tablet devices means that information can be made available to students at the exact time and place of need. This has the potential to reduce cognitive overload by providing students with “perfectly situated scaffolding”, as well as enable learning in a range of other ways. This paper will review uses of Augmented Reality both in mainstream society and in education, and discuss the pedagogical potentials afforded by the technology. Based on the prevalence of information delivery uses of Augmented Reality in Education, we argue the merit of having students design Augmented Reality experiences in order to develop their higher order thinking capabilities. A case study of “learning by design” using Augmented Reality in high school Visual Art is presented, with samples of student work and their feedback indicating that the...

A reverse‐engineering approach to subsystem structure identification

Abstract: Reverse-engineering is the process of extracting system abstractions and design information out of existing software systems. This process involves the identification of software artefacts in a particular subject system, the exploration of how these artefacts interact with one another, and their aggregation to form more abstract system representations that facilitate program understanding. This paper describes our approach to creating higher-level abstract representations of a subject system, which involves the identification of related components and dependencies, the construction of layered subsystem structures, and the computation of exact interfaces among subsystems. We show how top-down decompositions of a subject system can be (re)constructed via bottom-up subsystem composition. This process involves identifying groups of building blocks (e.g., variables, procedures, modules, and subsystems) using composition operations based on software engineering principles such as low coupling and high cohesion. The result is an architecture of layered subsystem structures. The structures are manipulated and recorded using the Rigi system, which consists of a distributed graph editor and a parsing system with a central repository. The editor provides graph filters and clustering operations to build and explore subsystem hierarchies interactively. The paper concludes with a detailed, step-by-step analysis of a 30-module software system using Rigi.
