Landscape Values And Wind Generation In West Mayo, Ireland, Ken Boyle
Landscape Values And Wind Generation In West Mayo, Ireland, Ken Boyle
Conference Papers
The landscape of west Mayo, in North West Ireland, is dominated and shrouded by an extensive area, 3,539Km2, of blanket peat soils. The landscape and its habitats have multiple values associated with them including a source of peat for fuel, agriculture, forestry, conservation, tourism, biomass production, tourism, cultural and archaeological. Historically communities have relied on peat as a source of energy and in the 20th century the state harvested peat on an industrial scale to generate electricity. Biomass production using willow (Salix spp) on cutover blanket peat and extensive planting, on deep peat, of Picea sitchensis and Pinus contorta was …

An Assessment Of The Accuracy Of Ppp In Remote Areas In Oman, Audrey Martin, Rashid Al Alawi

Traditionally, high accuracy Global Navigation Satellite Systems (GNSS) positioning has involved differential techniques. Such techniques significantly reduce or eliminate inherent biases in the GNSS measurement by referencing simultaneous measurements to one or more known reference stations. On a national scale, these differential techniques rely heavily on a costly spatial infrastructure of accurately known points usually occupied by Continually Operating Reference Stations (CORS). In recent years, the development of Precise Point Positioning (PPP) techniques have been shown to reduce many of the inherent observation errors and biases in GNSS solutions which eliminate the need for a ground based reference station. Such …

Available Work Rate Of A Reversible System Bounded By Constant Thermal Resistances Linked To Isothermal Reservoirs, Jim Mcgovern
Conference Papers
Exergy analysis is based on the concept of an idealized, all-enclosing reference environment that has infinite heat capacity and thermal conductivity, and is in equilibrium. The actual surroundings of a real plant such as a heat engine, a heat pump or a refrigerator may differ significantly from the ideal. First law performance parameters and second law rational efficiency are examined. The concepts of finite time thermodynamics are applied in an attempt to refine the concept of T0, the environmental reference temperature, thereby making exergy analysis more reflective of reality.

Detection Of Dns Based Covert Channels, Stephen Sheridan, Anthony Keane
Conference Papers
Information theft or data exfiltration, whether personal or corporate, is now a lucrative mainstay of cybercrime activity. Recent security reports have suggested that while information, such as credit card data is still a prime target, other data such as corporate secrets, employee files and intellectual property are increasingly sought after on the black market. Malicious actors that are intent on exfiltrating valuable data, usually employ some form of Advanced Persistent Threat (APT) in order to exfiltrate large amounts of data over a long period of time with a high degree of covertness. Botnets are prime examples of APTs that are …

Professional Formation Of Engineers: Enhancing The First Year Student Experience, Eileen Goold
Conference Papers
This paper reports on a study investigating engineering students’ perceptions of engineering practice and whether engineering students’ cognitive engagement benefits from bridging the gap between the technical issues in their education and the practical realities of modern engineering practice.
