A framework is developed for studying the implementation process, as a stepwise process in which an abstract specification is successively transformed to reach a final compilable specification adapted to the computer environment. In this context, an implementation relation is referred to as the relation which should link any ``valid'' implementation to its abstract formal specification. In other words, the implementation relation is intended to express formally the notion of validity. Our framework allows the exact characterization of the transformations which may take place at each step for a given implementation relation. This framework is essential for dealing with non-transitive implementation relations. In the second part of the paper, these results are exemplified in LOTOS on some existing relations, and an apparent paradox is presented. Some new results about these relations are also derived.

The implementation of the Water Framework Directive (EU 2000) requires a groundwater quality monitoring. It is used for characterisation of the 'good' chemical status of each groundwater body and for the restoration or protection purposes of those bodies already at 'good' status. Interpretative aspects are lying in the design of monitoring network and in the way of building global indicators. Attention is given here to the global chemical status of the groundwater bodies and to the role of diffuse pollution, much of which is brought via groundwater to surface water. Monitoring 'local' pollution associated with individual sites is not addressed. Groundwater bodies with different contrasted hydrogeology conditions, land use and topography have been considered to establish an approach for choosing an optimised monitoring network. Then, a quality assessment system has been developed and applied for qualifying the general status of each groundwater body. The use of non-dimensional indexes allows us to process with all kinds of chemical parameters in a normalised way and, by means of adequate aggregation rules, to qualify the general quality status of a groundwater body. The obtained diagnostic, even if not fully validated, is closely linked to the pragmatic objectives contained in the EU Water Directive. [less ▲]

The purpose of this note is to propose a complexity framework for the analysis of high multiplicity scheduling problems. Part of this framework relies on earlier work aiming at the definition of output-sensitive complexity measures for the analysis of algorithms which produce "large" outputs. However, different classes emerge according as we look at schedules as sets of starting times, or as related single-valued mappings. [less ▲]

OBJECTIVES: Different types of '-omics' data are becoming available in the post-genome era; still a single -omics assessment provides limited insights to understand the biological mechanism of complex diseases. Genomics, epigenomics and transcriptomics data provide insight into the molecular dysregulation of neoplastic diseases, among them urothelial bladder cancer (UBC). Here, we propose a detailed analytical framework necessary to achieve an adequate integration of the three sets of -omics data to ultimately identify previously hidden genetic mechanisms in UBC. METHODS: We built a multi-staged framework to study possible pair-wise combinations and integrated the data in three-way relationships. SNP genotypes, CpG methylation levels and gene expression levels were determined for a total of 70 individuals with UBC and with fresh tumour tissue available. RESULTS: We suggest two main hypothesis-based scenarios for gene regulation based on the -omics integration analysis, where DNA methylation affects gene expression and genetic variants co-regulate gene expression and DNA methylation. We identified several three-way trans-association 'hotspots' that are found at the molecular level and that deserve further studies. CONCLUSIONS: The proposed integrative framework allowed us to identify relationships at the whole-genome level providing some new biological insights and highlighting the importance of integrating -omics data.

The possibility for market participants to place their bids in all the markets of an interconnection irrespective of where they are physically connected is investigated in this paper. A mechanism is proposed for managing the resulting congestion. It consists in iteratively sharing the transmission line capacities between the different market operators based each time on their present schedules. The algorithm is applied on a small test system. The results are assessed in terms of their property of being Nash equilibria and of their distance of the set of Pareto optimal operating points. [less ▲]

The Kou watershed in south-western Burkina Faso has suffered from poor water management for several decades. Covering 1,800 km², this small watershed is the site of the second largest city in Burkina Faso (Bobo-Dioulasso), a former State-run irrigated rice scheme and several informal agricultural zones. Notwithstanding the abundance of water resources, most water users regularly face water shortages due to a population increase and low irrigation inefficiency. Local stakeholders therefore need low-cost, easy-to-use decision-support tools to enable them to monitor and exploit the water resources to best advantage at different spatial and user levels. A top to bottom series of adapted water management tools has been successfully installed to address current problems, from watershed level (top) to individual field level (bottom), and including the 1,200 ha irrigated rice scheme. Remote sensing techniques have been developed to map the agricultural lands. Combined with data from a network of hydrologic gauging stations, regional water-use maps have been compiled. SIMIS software is being used for the public-private management of the irrigated rice scheme. A simple field-crop-water balance model, AquaCrop, is being used by extension workers to draft optimal irrigation charts. Day to day water use on irrigated plots was monitored by soil humidity and crop canopy measurements. Each water management tool is applied independently, requiring only limited data, but their combined results are contributing to improved integrated water management. [less ▲]

Reliability of electrical transmission systems isvpresently managed by applying the deterministic N-1 criterion, or some variant thereof. This means that transmission systems are designed with at least one level of redundancy, regardless of the cost of doing so, or the severity of the risks they mitigate. In an operational context, the N-1 criterion provides a reliability target but it fails to accurately capture the dynamic nature of short-term threats to transmission systems. Ongoing research aims to overcome this shortcoming by proposing new probabilistic reliability criteria. Such new criteria are anticipated to rely heavily on component failure rate calculations. This paper provides a threat modelling framework, using the Icelandic transmission system as an example, highlighting the need for improved data collection and failure rate modelling. The feasibility of using threat credibility indicators to achieve spatio-temporal failure rates, given minimal data, is explored in a case study of the Icelandic transmission system. The paper closes with a discussion on the assumptions and simplifications that are implicitly made in the formulation, and the additional work required for such an approach to be included in existing practices. Specifically, this paper is concerned only with short term and real-time management of electrical transmission systems. [less ▲]

The Kou watershed, situated in the Southwestern part of Burkina Faso, has succumbed since a couple of decades to a typical theater play of anarchistic water management. With its 1.800 km², this small watershed includes the second largest city of Burkina Faso (Bobo-Dioulasso), a former state run irrigated rice scheme and several informal agricultural zones. Despite the abundance of water resources, most water users find themselves regularly faced with shortages due to an increase in population and low irrigation efficiencies. Local stakeholders are hence in need of easy to use and low-cost decision support tools for the monitoring and exploitation of the water resources at different spatial and user levels. A top-to-bottom string of adapted water management tools has successfully been installed to tackle the problems: from watershed (top) to field level (bottom), not to mention the 1200 ha irrigation scheme. Land use maps have been derived from satellite and aerial images. Combined with data from a network of hydrologic gauging stations, regional water use maps were established. Hot spots in inefficient water use could be geographically identified and more detailed actions undertaken. Scheme Information Management Information System (SIMIS) was put in place for the management of the regions irrigated rice scheme. A more equitable distribution for the ever diminishing available water resources could be elaborated. A public-private partnership was installed to guarantee its sustainability. Day to day water use on irrigated plots was monitored by soil humidity and crop canopy measurements. A simple field-crop-water balance model AquaCrop was calibrated and validated, and is used by extension workers to draft optimal irrigation charts. Each tool is applied independently, requiring only limited data; but their combined results contribute to an improved integrated water management. [less ▲]

The determination of comprehensive activity-travel patterns is important in the context of agent-based micro-simulation modelling. This paper presents an improved method based on profile Hidden Markov Models (pHMMs) able to include information related to the agents’ residential locations. As proposed in the framework of Liu et al. (2015), pHMMs only characterize activity-travel patterns from the activity sequences perspective. In this context, information related to the primary activity locations (e.g. home, work) is not available and, as a result, it cannot be extracted from the pHMMs themselves. With respect to this limitation, we propose to apply the framework of Liu et al. (2015) with an extension to include characterization of residential locations. Following the established guidelines, the activity sequences and their related residential locations are extracted from the activity-travel diaries in order to estimate the regularity of the activities as well as their sequential order. Subsequently, within each residential activity, we include a categorization at an aggregate level (provinces). The methodology is powerful as it characterizes any length of sequence, allowing the generation of unlimited agent plans with information about residential location. Regarding data collection, the activity-travel diaries are provided by the Belgian Household Daily Travel Survey (2010). The results obtained after the simulations indicate a good match between the predicted and observed residential locations at both the national and provincial levels. [less ▲]

Framing empirical research analyzes the construction (frame building) and influence (frame effects) of the frames with which different social agents interpret and communicate reality. Based on Entman’s (2004; 2008) and Kuypers’ (2008; 2009) contributions, this paper proposes and applies a qualitative methodology for the analysis of frame building in political discourse. It is located, therefore, on the strategic and methodological lines of framing research in political communication (Bartolomé; Rodríguez & Sádaba, 2012). As Kinder and Sanders state, frames are “invented and employed by political elites, often with an eye on advancing their own interests or ideologies, and intended to make favorable interpretations prevail” (Kinder & Sanders, 1990, p. 74). The paper includes a theoretical framework that reviews the evolution of framing literature in Communication, focusing especially on empirical studies. The contributions adopted for the elaboration of the methodology and the application process are explained in detail. The context of the case study, Bush’s discourse about the War on Terror on his trip to Europe in February 2005, is revised. Finally, the results obtained and the conclusions are detailed. [less ▲]

Public diplomacy is an international political communication activity to which States and other organizations resort in order to achieve political objectives abroad and to establish positive relations with foreign publics. It is an activity that has evolved to adapt to the new global context, adding new characteristics and giving place to the so-called “new public diplomacy”. One of the different variants of public diplomacy is mediatic diplomacy, whose end is to get the public diplomacy’s message transmitted by institutional media or to get a positive coverage by foreign media. This article proposes a specific process to apply the framing theory as a tool for political discourse analysis, an essential element of mediatic diplomacy. The process is applied to George W. Bush’s political discourse during the first months of the “War on Terror”. [less ▲]
