A smart tool for the diagnosis of Parkinsonian syndrome using wireless watches
No full textThis work is licensed under a Creative Commons Attribution 3.0 License.Early detection and diagnosis of Parkinson disease will provide a good chance for patients to take early actions and prevent its further development. In this paper, a smart tool for the diagnosis of Parkinsonian syndromes is designed and developed using low-cost Texas Instruments eZ430-Chronos wireless watches. With this smart tool, Parkinson Bradykinesia is detected based on the cycle of a human gait, with the watch worn on the foot, and Parkinson Tremor shaking is detected and differed by frequency 0 to 8 Hz on the arm in real-time with a developed statistical diagnosis chart. It can be used in small clinics as well as home environment due to its low-cost and easy-use property
Why aren't we all living in Smart Homes
No full textVisions of the Future, like the Jetsons cartoons, show homes which are smart and able to control household appliances, to make living easier and more comfortable. Although much research has been carried out into the effectiveness of different visualisation techniques for conveying useful energy consumption information to householders, and in techniques for controlling the timing and coordination of appliance use, these techniques have failed to achieve widespread penetration, and the vision still seems far from a reality. This paper examines the reasons why smart home technologies have so far failed to have any real impact, which is intricately intertwined with the design of visualisations in this context, and why we are not already living in Smart Homes. It examines these questions under four sections: Technology, Consumers, Electricity retailers and Government agencies, using examples from New Zealand’s electricity sector
Response to Commentary "efficacy of inspiratory muscle training in chronic heart failure patients"
No full textIn their letter Plentz and colleagues attempt to highlight discrepancies between their review work and that of Smart et al. Plentz and colleagues suggest that the search by Smart et al. was too narrow. We challenge Plentz and colleagues to find omitted studies that were published in the stipulated time frame as, in addition to the stipulated search, extensive hand searching was conducted. The discrepancy between the previous works and the work of Smart et al. may be explained by the fact that we only recorded papers where we were required to read more than the title (e.g. abstracts or full manuscripts) in order to come to a decision to exclude a study. Second, Plentz and colleagues suggest our review included too many studies, which perhaps contradicts their comment above? We do however acknowledge that journal word limits permitting the inclusion of a sensitivity analysis (e.g. removal of studies of Winkelmann and Laoutaris) may have been helpful in teasing out any effects of heterogenic studies
Intelligent Energy Optimization for User Intelligible Goals in Smart Home Environments
No full textIntelligent management of energy consumption is one of the key issues for future energy distribution systems, smart buildings, and consumer appliances. The problem can be tackled both from the point of view of the utility provider, with the intelligence embedded in the smart grid, or from the point of view of the consumer, thanks to suitable local energy management systems (EMS). Conserving energy, however, should respect the user requirements regarding the desired state of the environment, therefore an EMS should constantly and intelligently find the balance between user requirements and energy saving. The paper proposes a solution to this problem, based on explicit high-level modeling of user intentions and automatic control of device states through the solution and optimization of a constrained Boolean satisfiability problem. The proposed approach has been integrated into a smart environment framework, and promising preliminary results are reporte
Smart Grid Technologies in Europe: An Overview
No full textThe old electricity network infrastructure has proven to be inadequate, with respect to modern challenges such as alternative energy sources, electricity demand and energy saving policies. Moreover, Information and Communication Technologies (ICT) seem to have reached an adequate level of reliability and flexibility in order to support a new concept of electricity network—the smart grid. In this work, we will analyse the state-of-the-art of smart grids, in their technical, management, security, and optimization aspects. We will also provide a brief overview of the regulatory aspects involved in the development of a smart grid, mainly from the viewpoint of the European Unio
An investigation into the depiction of smart grid technology
No full textIncreasing climate change concerns and depletion of fossil fuels demand greater efficiency in electricity production and consumption. Smart Grid is a vision of an enhanced electricity grid that integrates the electric grid with communication and sensing technologies to improve energy delivery. A number of initiatives have been embarked upon to reach this vision. Databases of Smart Grid projects are being kept to hallmark the state of development and advise future project design. However, to date, there is no method of comparing projects‟ results. This means that it is difficult to identify the most successful projects. In addition, details of projects tend to be descriptive and there is no standard method of representing Smart Grid systems. The first Smart Grid technologies are about to be deployed in homes, and yet, there are little research examining how domestic consumers would react to a full set of Smart Grid technology. This is important because the opinions and participation of domestic consumers could lead to the success or failure of the Smart Grid system. This research aims to device a representation system that enables the comparison of smart grid technology available for the residential consumers in the UK. The objectives are to: (i) review and identify existing representations of home Smart Grid technology; (ii) review and identify the general system representation methods; (iii) develop a representation method that maps and enables the comparison of Smart Grid technology in homes; (iv) validate the design of the representation method with relevant stakeholders. Through a four step methodology these objectives were achieved.
Thirty Smart Grid diagrams taken from journals and conference papers were analysed and categorised into five groups based of the type of communication features they contained. The results from this analysis guided the development of a Smart Grid representation method. Two Smart Grid systems that are available on the market were depicted using the representation method and were used to validate the design through interviewing 10 residential electricity consumers. As an outcome, this research had delivered a validated representation method that could be used to depict electricity management systems. It could be adopted by energy companies to convey the functions and benefits of Smart Grid technologies to potential customers
A Systems Approach to the Smart Grid
No full textThis paper presents the case for using a systems approach to analyse the requirements and behaviours of the Smart Grid as well as designing relevant solutions. By linking systems thinking to agent-based modelling, we discuss how a Smart Grid can be modelled as Multi-Agent Systems by reviewing some related state-of-the-art research. This paper goes on to outline two research areas that we are developing, namely, demand response using dynamic pricing and emergent behaviours of a Smart Grid.This paper presents the case for using a systems approach to analyse the requirements and behaviours of the Smart Grid as well as designing relevant solutions.

Smart Regulation for Smart Grids
No full textClimate change and security of supply policies are driving us towards a decarbonization of the electricity system. It is in this context that smart grids are being discussed. Electricity grids, and hence their regulatory frameworks, have a key role to play in facilitating this transformation of the electricity system. In this paper, we analyze what is expected from grids and what are the regulatory tools that could be used to align the incentives of grid companies and grid users with what is expected from them. We look at three empirical cases to see which regulatory tools have already been applied and find that smart grids need a coherent regulatory framework addressing grid services, grid technology innovation and grid user participation to the ongoing grid innovation. The paper concludes with what appears to be a smart regulation for smart grids.Regulation, innovation, electricity, grids, transmission, distribution
Secure and energy-efficient multicast routing in smart grids
No full textA smart grid is a power system that uses information and communication technology to operate, monitor, and control data flows between the power generating source and the end user. It aims at high efficiency, reliability, and sustainability of the electricity supply process that is provided by the utility centre and is distributed from generation stations to clients. To this end, energy-efficient multicast communication is an important requirement to serve a group of residents in a neighbourhood. However, the multicast routing introduces new challenges in terms of secure operation of the smart grid and user privacy. In this paper, after having analysed the security threats for multicast-enabled smart grids, we propose a novel multicast routing protocol that is both sufficiently secure and energy efficient.We also evaluate the performance of the proposed protocol by means of computer simulations, in terms of its energy-efficient operation
