ICT Trust, Security and Dependability Research Strategy beyond 2010.

This paper, entitled ICT Trust, Security & Dependability Research strategy beyond 2010, will describe the final outputs of the IST SecurIST [1] project, whose objective was to create a clear European level strategy to drive ICT Security and Dependability research beyond 2010. The focus in the paper is on short to medium (up to 3 years) to long-term objectives (~3-10 years). This paper will develop the context of the project, the approach taken, research strategy, setting its objectives and results with reference of various inputs and outputs from a large constituency involved in ICT Trust, Security and Dependability areas that was ultimately co-ordinated by the SecurIST project

A Match in Time Saves Nine: Deterministic Online Matching With Delays

We consider the problem of online Min-cost Perfect Matching with Delays (MPMD) introduced by Emek et al. (STOC 2016). In this problem, an even number of requests appear in a metric space at different times and the goal of an online algorithm is to match them in pairs. In contrast to traditional online matching problems, in MPMD all requests appear online and an algorithm can match any pair of requests, but such decision may be delayed (e.g., to find a better match). The cost is the sum of matching distances and the introduced delays. We present the first deterministic online algorithm for this problem. Its competitive ratio is $O(m^{\log_2 5.5})$ $= O(m^{2.46})$, where $2 m$ is the number of requests. This is polynomial in the number of metric space points if all requests are given at different points. In particular, the bound does not depend on other parameters of the metric, such as its aspect ratio. Unlike previous (randomized) solutions for the MPMD problem, our algorithm does not need to know the metric space in advance

Developing general cultural awareness in a monocultural English as a foreign language context in a Mexican university: a wiki-based critical incident approach

© 2013 Association for Language Learning. This article explores what the ‘intercultural turn’ might mean in the case of teaching English to speakers of other languages (TESOL). The discussion is contextualised in what has been termed the ‘expanding circle’ of English and focuses on an English as a foreign language (EFL) class in a Mexican university, a context where the full implications of a shift from EFL to English as a lingua franca (ELF) have yet to be addressed. We consider how the intercultural turn might be understood in this Mexican context and then present the rationale for, and design of, a technology-based (wiki) extra-curricular pilot project which adopted less of an EFL/cultural and more of an ELF/intercultural approach. We evaluate the evidence from this small-scale project in terms of students\u27 developing general cultural awareness and suggest that this type of project, an example of the intercultural turn, might be more widely applicable in similar ‘expanding circle’ EFL contexts

A review of new and existing non-extractive techniques for monitoring marine protected areas

Publication history: Accepted - 23 June 2023; Published - 19 July 2023.Ocean biodiversity loss is being driven by several anthropogenic threats and significant efforts are required to halt losses and promote healthy marine ecosystems. The establishment of a network of Marine Protected Areas (MPAs) can help restrict damaging activities and have been recognised as a potential solution to aid marine conservation. When managed correctly they can deliver both ecological and socio-economic benefits. In recent times, MPA designations have increased rapidly while many countries have set future MPA targets for the decades ahead. An integral element of MPA management is adequate monitoring that collects data to assess if conservation objectives are being achieved. Data acquired by monitoring can vary widely as can the techniques employed to collect such data. Ideally, non-destructive and non-invasive methods are preferred to prevent damage to habitats and species, though this may rule out a number of traditional extractive sampling approaches such as dredges and trawls. Moreover, advances in ocean observation technologies enable the collection of large amounts of data at high resolutions, while automated data processing is beginning to make analyses more logistically feasible and less time-consuming. Therefore, developments to existing marine monitoring techniques and new emerging technologies have led to a diverse array of options when choosing to implement an MPA monitoring programme. Here, we present a review of new and existing non-extractive techniques which can be applied to MPA monitoring. We summarise their capabilities, applications, advantages, limitations and possible future developments. The review is intended to aid MPA managers and researchers in determining the suitability of available monitoring techniques based on data requirements and site conditions.This research was funded through the Marine Protected Area Monitoring and Management (MarPAMM) project, which is supported by the European Union’s INTERREG VA Programme, managed by the Special EU Programmes Body (SEUPB) with matching funding from the Government of Ireland, the Northern Ireland Executive, and the Scottish Government. This research was also carried out with the support of the Marine Institute under the Marine Research Programme with the support of the Irish Government

Crystallization of calcium carbonate and magnesium hydroxide in the heat exchangers of once-through multistage flash (MSF-OT) desalination process

YesIn this paper, a dynamic model of fouling is presented to predict the crystallization of calcium carbonate and magnesium hydroxide inside the condenser tubes of Once-Through Multistage Flash (MSF-OT) desalination process. The model considers the combination of kinetic and mass diffusion rates taking into account the effect of temperature, velocity and salinity of the seawater. The equations for seawater carbonate system are used to calculate the concentration of the seawater species. The effects of salinity and temperature on the solubility of calcium carbonate and magnesium hydroxide are also considered. The results reveal an increase in the fouling inside the tubes caused by crystallization of CaCO3 and Mg(OH)2 with increase in the stage temperature. The intake seawater temperature and the Top Brine Temperature (TBT) are varied to investigate their impact on the fouling process. The results show that the (TBT) has greater impact than the seawater temperature on increasing the fouling
