Governance and economics of smart cities: opportunities and challenges

Anand, Prathivadi B., Navio-Marco, J. 11 October 2018 (has links)
Yes / This editorial introduction to this special issue provides an overview and a conceptual framework of governance and economics of smart cities. We begin with a discussion of the background to smart cities and then it focuses on the key challenges for consideration in smart city economics. Here it is argued that there are four dimensions to smart city economics: the first is regarding the scale of global market for smart cities; the second issue concerns data to be used for smart city projects; the third concerns market competition and structure and the fourth concerns the impact on local economy. Likewise, smart city governance framework has to be considered a layered and multi-level concept focusing on issues of transparency and accountability to the citizens.

Secure and compromise-resilient architecture for advanced metering infrastructure

Alfaheid, Khalid 01 March 2011 (has links)
In recent years, the Smart Grid has grown to be the solution for future electrical energy that promises to avoid blackouts as well as to be energy efficient, environmentally and customer-friendly. In Smart Grid, the customer-friendly applications are a key element that provides the feature for recognizing the active expenditure of current energy via an Advanced Metering Infrastructure (AMI) subsystem. In fact, the smart meter, as a major part of AMI that is installed in residences, which provides more details about a consumer‟s usage. The smart meter measures hour-by-hour usage of a house, and then instantly transmits the record to the utility via two-way communications, unlike the previous electrical system that collects all usage monthly. However, the live measurement of the usage creates a potential privacy leak since each electrical usage records the behaviour of consumers in the home. Therefore, any communication channel between customers and utility should have some sort of confidentiality which protects consumer privacy. In reality, smart meters are generally located in an insecure area of the house (outside), therefore anyone can potentially tamper with the device, noting the fact that it is low-end device. As a result, there is a great possibility of compromising the smart meter, resulting in disclosure of consumer usage. Actually, the nature of a smart meter, and the cost constraints, create a challenge to secure the network. Therefore, the dual motivating problems are the protection of consumer privacy as well as achieving cost efficiency. In this research, we propose a new secure and compromise resilient architecture that continues two major components: a smart meters compromise attack detection scheme and a secure usage reporting protocol. Firstly, the smart meters compromise attack detection scheme improves the security of the smart meter, preventing an adversary from compromising the smart meter. Secondly, the secure usage reporting protocol improves the security of communication between the smart meter and the utility, preventing an adversary from identifying each household's usage reported by smart meters. / UOIT

Design and Implementation of SIM Functionality for TETRA-system on a Smart Card / Design och implementation av SIM-funktionalitet i ett smartcard för TETRA-systemet

Olofsson, Jonas January 2012 (has links)
TETRA is an open radio standard developed by ETSI. It is specifically designed for use bygovernment agencies, emergency services such as police forces, fire departments, and ambulance,public safety networks, train radios, transport services, and the military. The TETRAstandard is used in the Swedish public safety net Rakel. Today the hand-held devices inRakel do not use a SIM card to hold the user identity. Instead, the terminal is personalisedby hard coding the user information in the terminal. As the users group grows a need forSIM cards will probably emerge since it simplifies the handling of the users for the networkadministrator, and allows the user to replace a broken terminal by simple moving his/herSIM card to another terminal. This master thesis examines the TSIM standard and extractsa specification of requirements, proposes a suitable software architecture, and partially implementsTSIM functionality on a smart card. The conclusion is that a TSIM applicationcan be integrated with an E2EE application but some modifications are needed compared toonly having the TSIM functionality in the smart card. The design and architecture describedin this master thesis can be used in systems that already use the SIM slot of the hand-helddevices for a smart card that extends the functionality of the terminal.

Economic evaluation of smart well technology

Al Omair, Abdullatif A. 17 September 2007 (has links)
The demand of oil and gas resources is high and the forecasts show a trend for higher requirements in the future. More unconventional resource exploitation along with an increase in the total recovery in current producing fields is required. At this pivotal time the role of emerging technologies is of at most importance. Smart or intelligent well technology is one of the up and coming technologies that have been developed to assist improvements in field development outcome. In this paper a comprehensive review of this technology has been discussed. The possible reservoir environments in which smart well technology could be used and also, the possible benefits that could be realized by utilizing smart well technology has been discussed. The economic impact of smart well technology has been studied thoroughly. Five field cases were used to evaluate the economics of smart well technology in various production environments. Real field data along with best estimate of smart well technology pricings were used in this research. I have used different comparisons between smart well cases and conventional completion to illustrate the economic differences between the different completion scenarios. Based on the research, I have realized that all the smart well cases showed a better economic return than conventional completions. The offshore cases showed a good economic environment for smart well technology. Large onshore developments with smart well technology can also provide a lucrative economic return. These situations can increase the overall economic return and ultimate recovery which will assist in meeting some of the oil demand around the globe.
