This collaborative research work between multiple universities demonstrates and rigorously analyses a number of innovative and new teaching methodologies that incorporate the use of new technology to encourage students to participate and take an active role in learning. More precisely, we introduce the ‘Automatic Virtual Lecturing’ teaching methodology which utilises live student feedback to dynamically reorder the lecture slides content of the teacher combined with an online video repository to substitute repeated lecture presentations both during and after class. We also present research outputs of our patented teaching concept SHARED and collaborative learning which creates a paperless collaborative learning environment in our classrooms where students can take virtual notes on their wooden tabletops, while the teacher can give instant feedback on student progress without leaving his personal desk. The methodologies were researched thoroughly in a number of classrooms which resulted in a significant increase in the performance of the students, showing real promise of such unique teaching methodologies. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Environmental consciousness has become critical in the design and operation of globally integrated supply chain networks. This research examines the carbon footprint across supply chains and thus contributes to the knowledge and practice of green supply chain management. The analytical model uses the long-range Lagrangian and the Eulerian transport methods. Analytical and finite difference methods are used to approximate the three-dimensional infinite footprint model. A simplified numerical example validates and illustrates the proposed approach. The results show that carbon emissions across stages in a supply chain can constitute a significant threat that warrants careful attention in the design phase of supply chains. © 2010 Elsevier B.V.All rights reserved.

An entity passes through four stages of life cycles during its lifespan. These life cycle stages reflect a set of financial characteristics that lead to different information on income and cash flows, which are also supplied by the cash flow statement. Therefore, combining the life cycle theory with an analysis of the cash flow statement may be useful as a performance measure and an indication of how entities are managing the flow of their funds. This paper evaluates an entity in the food and beverage sector by means of income and cash flow during the growth cycle. Steps are followed for analysing income and cash flows and for comparing the application thereof to a benchmark in the growth phase of an entity's life cycle. In theory an entity will have typical income and cash flow patterns during each life cycle stage. © 2017 Inderscience Enterprises Ltd.

We consider the pressure and correlation functions of d-dimensional classical continuous models of Kac type. We prove that if the kth moments of the potential exist, then the system cannot have phase transitions of order lower than k. We also obtain a better formula for the higher derivatives of the pressure that leads to more precise estimates of the truncated correlations. © 2017 World Scientific Publishing Company.

As large-scale sensor networks become more feasible, properties such as stateless nature and low maintenance overhead make position-based routing increasingly more attractive. Motivated by the fact that sensor networks would probably be deployed in a three-dimensional space, we present a novel 3D geographical routing (3DGR) algorithm that makes use of the position information to route packets from sources to destinations with high path quality and reliability. The locality and high scalability of this algorithm make it suitable for wireless sensor networks. It provides high adaptability to changes in topology and recovery of link failures which increases its reliability. We also incorporate battery-aware energy efficient schemes to increase the overall lifetime of the network. To reduce latency, a method of keeping a small record of recent paths is used. We also show that location errors will still result in good performance of our algorithm while the same assumptions might yield bad performance or even complete failures in other popular geographical routing algorithms. We evaluate the 3DGR protocol using simulation. Compared to other geographic routing algorithms, we find that 3DGR exhibits noticeably longer network lifetime, smaller path stretch, smaller end-to-end delay, and better packet delivery ratio.

Integrating social presence theory and social identity theory, this study brings system design and social influence aspects together to explain their joint effects on knowledge contribution in virtual communities (VCs). Different from most prior information systems (IS) research that adopts a uni-dimensional approach and restricts social presence to be the subjective nature of media, we developed and empirically tested a model explaining the effects of multi-dimensional social presence on social identification processes and knowledge contribution. An online survey was conducted with four different VCs of interest. The results showed the difference in relative contribution of social presence dimensions on social identity as well as knowledge contribution. Both practical and theoretical implications are discussed. © 2010 Taylor & Francis.

Common transverse reinforcement of reinforced concrete members with circular cross-section consists of round ties or spirals. Its purpose in members that are not subjected to significant shear loading is to provide proper confinement for concrete, and eliminate buckling of the longitudinal reinforcement bars. If spirals are to be used as both shear enabler and confiner for reinforced concrete beams then, under combined action of moment and shear, spirals will be required to provide or contribute to proper shear resistance. Hence, a proper assessment for spiral shear contribution is required. The validity of concepts which underline current methods for shear design used in design codes will be investigated in this paper, especially for beams with the shear configuration, which violates basic code rules on forming a truss. A simplified sectional model based on sectional crack analysis and a corresponding approach in assessing the shear contribution of spiral shear reinforcement are presented. A method for evaluating the shear capacity of beams with spirals has also been proposed.

The advances in computer science and structural designs are deeply intertwined. Rising energy costs and a growing green movement are driving the adoption of Wireless Sensor Networks (WSN) for building automation. While previous WSN products have been applied in a variety of smart applications including supply chains and industrial applications, a cross industry effort between civil engineers and network engineers is underway to unify sensor networks with construction management that will simplify development, attract new entrants, and encourage innovation. With the prospect of installing sensors almost anywhere, buildings can optimize their energy consumption, improve safety and security, and reduce operating expenses. We model a sensor node as a replacement of a solar panel. A significant efficiency increase of solar energy gains can only be obtained by optimal exposure of the panels to sunlight. In this paper, we propose a system that controls the movement of rotating buildings in order to optimize the energy gained by the use of solar panels installed both on the building rooftop horizontally and on the sides of the building vertically. © 2013 IEEE.

Various and independent studies are showing that an exponential increase of chronic diseases (CDs) is exhausting governmental and private healthcare systems to an extent that some countries allocate half of their budget to healthcare systems. To benefit from the IT development, e-health monitoring and prevention approaches revealed to be among top promising solutions. In fact, well-implemented monitoring and prevention schemes have reported a decent reduction of CDs risk and have narrowed their effects, on both patients' health conditions and on government budget spent on healthcare. In this paper, we propose a framework to collect patients' data in real time, perform appropriate nonintrusive monitoring, and propose medical and/or life style engagements, whenever needed and appropriate. The framework, which relies on service-oriented architecture (SOA) and the Cloud, allows a seamless integration of different technologies, applications, and services. It also integrates mobile technologies to smoothly collect and communicate vital data from a patient's wearable biosensors while considering the mobile devices' limited capabilities and power drainage in addition to intermittent network disconnections. Then, data are stored in the Cloud and made available via SOA to allow easy access by physicians, paramedics, or any other authorized entity. A case study has been developed to evaluate the usability of the framework, and the preliminary results that have been analyzed are showing very promising results. © 2013 IEEE.
