Localization for Anchoritic Sensor Networks

We introduce a class of anchoritic sensor networks, where communications between sensor nodes is undesirable or infeasible, e.g., due to harsh environment, energy constraints, or security considerations

The role of built environment energy efficiency in a sustainable UK energy economy

Energy efficiency in the built environment can make significant contributions to a sustainable energy economy. In order to achieve this, greater public awareness of the importance of energy efficiency is required. In the short term, new efficient domestic appliances, building technologies, legislation quantifying building plant performance, and improved building regulations to include installed plant will be required. Continuing these improvements in the longer term is likely to see the adoption of small-scale renewable technologies embedded in the building fabric. Internet-based energy services will see low-cost building energy management and control delivered to the mass market in order that plant can be operated and maintained at optimum performance levels and energy savings quantified. There are many technology options for improved energy performance of the building fabric and energy systems and it's not yet clear which will prove to be the most economic. Therefore, flexibility is needed in legislation and energy-efficiency initiatives

TECHNICAL DOCUMENTATION OF I3E MODEL VERSION 2. ESRI SURVEY AND STATISTICAL REPORT SERIES NUMBER 77 September 2019

This paper provides a technical description of the Ireland Environment, Energy and Economy (I3E) model. The I3E model is an intertemporal computable general equilibrium model with multiple firms, one representative household group, multiple commodities, government, enterprises, and rest of the world accounts. It describes the Irish economy in sectoral detail. This model includes a detailed description of energy inputs and concomitant greenhouse gas emissions and has been developed with the purpose of investigating the economic and environmental impacts of climate policies for Ireland

Enlightening the European Debate : Environment, Energy and Climate

The environment, energy and climate are transboundary issues that require cooperative action to sustainably address. To meet our energy requirements, both the UK and Europe are heavily reliant on energy imports. As international concerns rise over the impacts of climate change and over increasing levels of geopolitical unrest, UK Government energy policy must balance the need for competitive energy prices, with the requirements to ensure security of supply and to achieve environmental sustainability. Much of the UK’s environmental policy and legislation derives from EU Directives. Some sectors of industry may argue that this imposes a burden on their business, whilst others may argue that it leads to stability of Government policies and that it enables long-term decision-making and investment. Environmental groups do contend that European Directives provide a much-needed safety net, to protect the environment over timescales longer than a UK electoral cycle. This safety net is particularly effective because the successful implementation of EU Directives must be evidenced, protecting the progress of these policies, particularly during periods of financial stress.As part of a larger grouping of countries, negotiations on the world stage (such as climate negotiations) can be conducted with more authority than would be possible as an individual country, since the countries represented by the EU collectively represent a larger proportion of the global population, and account for a larger proportion of consumption and emissions. Cross-European R&D projects have a wider geographical scope, cover a broader range of environments and draw upon a larger pool of skills and researchers than would be possible if projects were centred within a single country. Such projects are facilitated by a number of EU mechanisms– though it is possible that non-EU countries can gain access to EU research activities, e.g. through associate country status.The implications for energy, environment and climate, of a move to leave the European Union are not clear. It is clear, however, that environmental policy in the UK has historically been driven by European legislation, that the UK is deeply embedded within the European energy market, and that the UK (and European) economies are heavily reliant on energy imports. Whatever the UK decides, it is critical that improved energy security remains a Government priority, and that we adopt a move towards a fully integrated energy, environmental and climate policy

Energy efficiency of error correction on wireless systems

Since high error rates are inevitable to the wireless environment, energy-efficient error-control is an important issue for mobile computing systems. We have studied the energy efficiency of two different error correction mechanisms and have measured the efficiency of an implementation in software. We show that it is not sufficient to concentrate on the energy efficiency of error control mechanisms only, but the required extra energy consumed by the wireless interface should be incorporated as well. A model is presented that can be used to determine an energy-efficient error correction scheme of a minimal system consisting of a general purpose processor and a wireless interface. As an example we have determined these error correction parameters on two systems with a WaveLAN interfac

A Socio-technical Analysis of Interdependent Infrastructures among the Built Environment, Energy, and Transportation Systems at the Navy Yard and the Philadelphia Metropolitan Region, USA

This paper reports on a research initiative that explores the interdependencies of the system of systems — the built environment, energy, and transportation — related to the redevelopment of The Navy Yard in Philadelphia and the Philadelphia Metropolitan Region. The overarching goal of the project is a clearer understanding of the dynamics of multi-scale interactions and interdependencies of systems of sociotechnical systems that will be useful to system practitioners. The understanding and the subsequent planning and design of sociotechnical systems are “wicked” problems and one characteristic is there is no definitive formulation. One of the main findings or lessons learned of the work reported for the understanding of interdependencies of infrastructure is the identification of what are the problems or challenges because for wicked problems “[t]he formulation of the problem is the problem!” We find that systems practitioners have an overarching concern of a fragmented regional policy and decision making process. Four main themes of 1. Vulnerability of aging infrastructure, 2. Integration of emerging technology into existing infrastructure, 3. Lifestyle and value changes, and 4. Financial innovations were identified as challenges. Continuing research work explores three possible infrastructure projects for further study as well as the development of a high-level systems of systems model. The principle outcome is the initiation of a planning process so that the system practitioners will learn to better understand the connections among related sociotechnical systems and the constellation of problems they face not within their immediate scope of responsibility yet influences the operations of their systems

Optimization of depth-based routing for underwater wireless sensor networks through intelligent assignment of initial energy

Underwater Wireless Sensor Networks (UWSNs) are extensively used to explore the diverse marine environment. Energy efficiency is one of the main concerns regarding performance of UWSNs. In a cooperative wireless sensor network, nodes with no energy are known as coverage holes. These coverage holes are created due to non-uniform energy utilization by the sensor nodes in the network. These coverage holes degrade the performance and reduce the lifetime of UWSNs. In this paper, we present an Intelligent Depth Based Routing (IDBR) scheme which addresses this issue and contributes towards maximization of network lifetime. In our proposed scheme, we allocate initial energy to the sensor nodes according to their usage requirements. This idea is helpful to balance energy consumption amongst the nodes and keep the network functional for a longer time as evidenced by the results provided
