Abstract: Since Technology Computer Aided Design (TCAD) is an important component of modern semiconductor manufacturing, a new framework is needed for microelectronics education. An integrated measurement-based microelectronics and VLSI engineering laboratory with simulation-based technology CAD laboratory is described. An Internet-based laboratory management system for monitoring and control of a real-time measurement system interfaced via a dedicated local computer is discussed. The management system allows the remote students to conduct remote experiments, perform monitoring and control of the experimental setup, and collect data from the experiment through the network link as if the student is physically in a conventional laboratory. The management system is also capable of evaluating of a student’s performance and grading laboratory courses that involve preliminary quiz and viva-voce examinations, checking of experimental data and submitted online laboratory reports. The proposed online TCAD teaching methodology will provide an opportunity for expanding microelectronics education.

Abstract: Cranial morphology in lepidosaurs is highly disparate and characterised by the frequent loss or reduction of bony elements. In varanids and geckos, the loss of the postorbital bar is associated with changes in skull shape, but the mechanical principles underlying this variation remain poorly understood. Here, we sought to determine how the overall cranial architecture and the presence of the postorbital bar relate to the loading and deformation of the cranial bones during biting in lepidosaurs. Using computer-based simulation techniques, we compared cranial biomechanics in the varanid Varanus niloticus and the teiid Salvator merianae, two large, active foragers. The overall strain magnitude and distribution across the cranium were similar in the two species, despite lower strain gradients in V. niloticus. In S. merianae, the postorbital bar is important for resistance of the cranium to feeding loads. The postorbital ligament, which in varanids partially replaces the postorbital bar, does not affect bone strain. Our results suggest that the reduction of the postorbital bar impaired neither biting performance nor the structural resistance of the cranium to feeding loads in V. niloticus. Differences in bone strain between the two species might reflect demands imposed by feeding and non-feeding functions on cranial shape. Beyond variation in cranial bone strain related to species-specific morphological differences, our results reveal that similar mechanical behaviour is shared by lizards with distinct cranial shapes. Contrary to the situation in mammals, the morphology of the circumorbital region, calvaria and palate appears to be important for withstanding high feeding loads in these lizards.

Abstract: Modern semiconductor manufacturing is recognized as a specialized field in electrical engineering curricula. Teaching micro- and nanoelectronics in university environment is a challenging task and a new framework is needed. An integrated measurement-based microelectronics laboratory along with technology computer aided design (TCAD) simulation laboratory has been developed and is in use for imparting hands-on laboratory experience to the students. An internet-based laboratory management system for monitoring and control of a real-time measurement system interfaced via a dedicated local computer is discussed. TCAD process/device simulations generate a vast amount of data and handling of the data is a challenge for web-based applications. A simple architecture for implementation, visualization and analyses of the generated data from process/device simulations is reported.

Abstract: Regulatory Technology (RegTech) is an emerging set of computing and network-based information systems and practices intended to enhance and improve regulatory compliance processes. Such technologies rely on collecting exclusive information from the environment and humans through automated Internet of Things (IoT) sensors and self-reported data. The key enablers of RegTech are the increased capabilities and reduced cost of IoT and Artificial Intelligence (AI) technologies. This article focuses on a survey of RegTech, highlighting the recent developments in various sectors. This work identifies the characteristics of existing implementations of RegTech applications in the financial industry. It examines the critical features that non-financial industries such as agriculture must address when using such technologies. We investigate the suitability of existing technologies applied in financial sectors to other industries and the potential gaps to be filled between them in terms of designing information systems for regulatory frameworks. This includes identifying specific operational parameters that are key differences between the financial and non-financial sectors that can be supported with IoT and AI technologies. These can be used by both producers of goods and services and regulators who need an affordable and efficient supervision method for managing relevant organizations.

Abstract: Smart workplace Internet of Things (IoT) solutions rely on several sensors deployed efficiently in the workplace environment to collect accurate data to meet system goals. A vital issue for these sensor-based IoT solutions is privacy. Ideally, the occupants must be monitored discreetly, and the strategies for maintaining privacy are dependent on the nature of the data required. This paper proposes a new sensor design approach for IoT solutions in the workplace that protects occupants’ privacy. We focus on a novel sensor that autonomously detects and captures human movements in the office to monitor a person’s sedentary behavior. The sensor guides an eHealth solution that uses continuous feedback about desk behaviors to prompt healthy movement breaks for seated workers. The proposed sensor and its privacy-preserving characteristics can enhance the eHealth solution system’s performance. Compared to self-reporting, intrusive, and other data collection techniques, this sensor can collect the information reliably and timely. We also present the data analysis specific to this new sensor that measures two physical distance parameters in real-time and uses their difference to determine human actions. This architecture aims to collect precise data at the sensor design level rather than to protect privacy during the data analysis phase.

Abstract: The role of soft tissues in skull biomechanics remains poorly understood. Not least, the chondrocranium, the portion of the braincase which persists as cartilage with varying degrees of mineralization. It also remains commonplace to overlook the biomechanical role of sutures despite evidence that they alter strain distribution. Here, we examine the role of both the sutures and the chondrocranium in the South American tegu lizard Salvator merianae . We use multi-body dynamics analysis (MDA) to provide realistic loading conditions for anterior and posterior unilateral biting and a detailed finite element model to examine strain magnitude and distribution. We find that strains within the chondrocranium are greatest during anterior biting and are primarily tensile also that strain within the cranium is not greatly reduced by the presence of the chondrocranium unless it is given the same material properties as bone. This result contradicts previous suggestions that the anterior portion (the nasal septum) acts as a supporting structure. Inclusion of sutures to the cranium model not only increases overall strain magnitudes but also leads to a more complex distribution of tension and compression rather than that of a beam under sagittal bending.

Abstract: Practical learning activities are effective ways to increase the interest of students in Science, Technology, Engineering and Mathematics (STEM) topics. Attracting school students to STEM careers is a challenge in many parts of the world. Remote Access Laboratories (RAL) allow for offsite control of state-of-the-art science and technology experiments. Such learning activities, while mostly used in universities, can also provide additional learning opportunities in schools. Current RAL technologies are targeted at undergraduate engineering education and offer limited operational autonomy. Opportunities for collaboration and experiment design are not well supported. However, both are important components of STEM education in schools. This paper discusses how RAL can be adapted to better support enquiry based learning in the context of STEM education. The limitations of current architectures are discussed and approaches to address these are presented.

Abstract: Remote Access Laboratories are being used around the globe to enable engineering students to practice practical skills and enhance their knowledge through hands-on experimentation. These facilities also increase access by allowing users to undertake experiments anywhere anytime thus offering more flexibility and mobility. Several RAL systems have successfully met these goals. However, the role of experiment designers has rarely being explored or expanded since the conception of RAL systems. Experiments are designed and put on internet by a small group of experts in their respective fields. While these systems have been successful for universities where experts and suitable environment are available, they have rarely been used in the schools and Science, Technology, Engineering and Mathematics (STEM) education. As the pedagogical design is now seen as a critical development in the instigation of new experiments, any RAL for STEM education initiative must address pedagogical considerations from the onset. In this paper, the common attributes of the leading RAL systems are discussed and the basic denominators are identified to establish common feature that are widely implemented in RAL systems. Limitations for their use in STEM education are analysed. The paper concludes that RAL architectures need to incorporate new aspects such as the peer-to-peer access paradigm in order to become viable STEM-based education tools.

Abstract: Augmented Reality (AR) is the process of overlaying meaningful interactive information in a live video stream for creating an enriched visual experience for users. Within Remote Access Laboratories (RAL) this enables users to gain design experience along with gaining knowledge about the particular experiment in question and potentially collaborate on design experiences. This paper focuses on the issues related to the applications of AR in RAL, the levels of AR in context of RAL and their effect on the learning tools. This paper also discusses the challenges of integrating a Natural User interface into the AR for RAL experiments. Finally it presets two ex le applications for AR in RAL experiment - Virtual Objects Creation and Object Identification and Tagging.

Abstract: The rapid growth of modern Radio Frequency (RF) and wireless communication systems requires experienced professionals in the RF and wireless areas. In the curriculum of engineering education, university departments are introducing courses on high frequency telecommunication or radio communication related courses to equip students for the needs of industry. Effective learning in education can only be achieved by combining theoretical course with the corresponding laboratory. Distant access of robot-supported laboratories through the Internet is an important and new issue in distance education. This study is an application of new technologies for active learning methodologies, in order to increase both the self-learning and comprehension of the students. This study aims to find out requirements and needs to be fulfilled in developing a robot-supported remote-controlled RF and wireless laboratory. Development and implementation of a robot-operated internet-based RF and wireless laboratory is described in detail.

Abstract: The lizard species Salvator ‘ Tupinambis ’ merianae and Varanus ornatus evolved independently in South America and Africa but share similar ecology and feeding behaviour, despite having notable differences in their skull structure. Tupinambis has a compact, relatively short and wide snout, whereas that of Varanus is more slender and narrow. In addition, a postorbital bar (POB) is present in Tupinambis but absent in Varanus , and the former lacks the mid-frontal suture that is present in the latter. Here, we explore the biomechanical significance of these differences using 3D computer-based mechanical simulations based on micro-computed tomography, detailed muscle dissections, and in vivo data. First, we simulated muscle activity and joint-reaction forces during biting using Multibody Dynamics Analysis. Then, the forces calculated from these models were used as an input for Finite Element Analysis, to investigate and compare the strains of the skull in these two species. The effects of the presence/absence of structures, such as the POB, were investigated by constructing artificial models which geometry was altered. Our results indicate that strains in the skull bones are lower in Tupinambis than in Varanus , in particular at the back of the skull. The presence of a POB clearly reduces the strains in the bones during posterior biting in Tupinambis , but not in Varanus . Our results hence highlight how the morphological differences between these two taxa affect the mechanical behaviour of their respective skulls during feeding.

Abstract: Remote Access Laboratories (RAL) are online platforms for performing experiments from remote locations usually following a centralised service oriented paradigm. This short article presents RALfie - Remote Access Laboratories for Fun, Innovation and Education using a peer-to-peer RAL architecture where some participants or makers can create, host and share experiments for other users. The system is built upon a VPN service that establishes end-to-end connections between learner and makers’ experiential rigs. A graphical programming platform - SNAP is the basis of programming and designing the interface with the experimental rig. The experiments are then shard using an activity-based learning strategy that presents the experiments as a set of hierarchical groups of activities or activities. This distributed design of RAL allows more hands-on experience to build experimental setup and provides opportunities to collaborate with fellow peers. The environment is suitable foe STEM Education. This approach requires the makers among the users to create and host the experiments, which demand certain responsibilities and offers new learning opportunities.

Abstract: Mobile devices are becoming more powerful, reliable and common every year. Hence we can use mobile devices for conducting laboratory sessions in distance education. This paper discusses issues of integrating Short Message Service (SMS) to operate instruments of hardware-based remotely triggered laboratories. Components of the system include searching an experiment, performing experiment, result handling, error handling and method of exchanging information. It is designed using the National Instruments (NI) Laboratory Virtual Instrument Engineering Workbench (LabVIEW) development system and web services. The scheme will enable students to conduct hardware experiments with mobile devices using SMS from anywhere and anytime.
