Introduction to the special issue: Applications of internet of things

© 2018 by the authors. This editorial introduces the special issue, entitled "Applications of Internet of Things", of Symmetry. The topics covered in this issue fall under four main parts: (I) communication techniques and applications, (II) data science techniques and applications, (III) smart transportation, and (IV) smart homes. Four papers on sensing techniques and applications are included as follows: (1) "Reliability of improved cooperative communication over wireless sensor networks", by Chen et al.; (2) "User classification in crowdsourcing-based cooperative spectrum sensing", by Zhai andWang; (3) "IoT's tiny steps towards 5G: Telco's perspective", by Cero et al.; and (4) "An Internet of things area coverage analyzer (ITHACA) for complex topographical scenarios", by Parada et al. One paper on data science techniques and applications is as follows: "Internet of things: a scientometric review", by Ruiz-Rosero et al. Two papers on smart transportation are as follows: (1) "An Internet of things approach for extracting featured data using an AIS database: an application based on the viewpoint of connected ships", by He et al.; and (2) "The development of key technologies in applications of vessels connected to the Internet", by Tian et al. Two papers on smart home are as follows: (1) "A novel approach based on time cluster for activity recognition of daily living in smart homes", by Liu et al.; and (2) "IoT-based image recognition system for smart home-delivered meal services", by Tseng et al

SikkerhetsLøypa-Knowledge Toward Sustainable and Secure Paths of Creative and Critical Digital Skills

Children spend numerous hours on the Internet daily. While online, they meet a great number of opportunities as well as risks. Of these risks, cyber bullying and privacy violations are of major concern, in addition to exploitation and child pornography. Our hypothesis is that the solution is not to keep children and teens away from the Internet, but to ensure that young citizens are empowered with the necessary knowledge and skill set to become critical consumers and creators of new secure and sustainable digital services and products. Our objective is to develop a knowledge and skill set base and offer learning through playful solutions for empowering children and young people with creative and critical digital skills, in an engaging and motivating way. The aim is to build on the method and lessons learns of Kodeløypa, one of the scientific offerings for children at the Norwegian University of Science and Technology (NTNU), and the related scientific efforts made to empower a new generation of online users to avoid risks in the modern digital society. The project, SikkerhetsLøypa, is highly inter-disciplinary and spans across the fields of information security, user experience, software engineering, and computer science education. The scientific results of this project aims at strengthen education methods and practices in secure and privacy-aware behavior in the digital world.submittedVersio

Enhancing learning management systems to better support Computer Science education

Many individual instructors -- and, in some cases, entire universities -- are gravitating towards the use of comprehensive learning management systems (LMSs), such as Blackboard and Moodle, for managing courses and enhancing student learning. As useful as LMSs are, they are short on features that meet certain needs specific to computer science education. On the other hand, computer science educators have developed--and continue to develop-computer-based software tools that aid in management, teaching, and/or learning in computer science courses. In this report we provide an overview of current CS specific on-line learning resources and guidance on how one might best go about extending an LMS to include such tools and resources. We refer to an LMS that is extended specifically for computer science education as a Computing Augmented Learning Management System, or CALMS. We also discuss sound pedagogical practices and some practical and technical principles for building a CALMS. However, we do not go into details of creating a plug-in for some specific LMS. Further, the report does not favor one LMS over another as the foundation for a CALMS
