The idea on Linked Open Data (LOD) for Disaster Management was stimulated by the experience with the integration of heterogeneous environmental data based on well-known OGC based web services. A lot of spatial data is available 'via the Web' but not “really on the web': many datasets can be viewed, queried and downloaded via web services, but it is usually not possible to reference an entity wi...
A huge amount of geographical datasets are becoming available in distributed environments like Spatial Data Infrastructures (SDI). These datasets are very heterogeneous since they come from different independent sources and surveys and are structured in different formats. In the context of a national SDI that needs to assure an adequate quality level of the data it provides, it is necessary to ...
Technological development and increasing awareness of geodata and its use has caused an explosion of digital content. However, this was not accompanied by dissemination and accessibility measures. Spatial Data Infrastructures (SDIs), allowing extensive reuse of geoinformation, may offer a solution. SDIs face organisational, technological, legal, cultural and linguistic challenges. The enrichmen...
OBJECTIVE The Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) is a validated instrument for assessing organ damage in systemic lupus erythematosus (SLE). Trained physicians must complete it, thus limiting utility where this is impossible. METHODS We developed and pilot tested a self-assessed organ damage instrument, the Lupus Damage Index...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
drought is random and nonlinear phenomenon and using linear stochastic models, nonlinear artificial neural network and hybrid models is advantaged for drought forecasting. this paper presents the performances of autoregressive integrated moving average (arima), direct multi-step neural network (dmsnn), recursive multi-step neural network (rmsnn), hybrid stochastic neural network of directive ap...
A survey has been performed to determine the measurement requirements of space power related parameters for anticipated SDI systems. These requirements have been compared to present state-of-the-art metrology capabilities as represented by the calibration capabilities of the National Institute of Standards and Technology. Metrology areas where present state-of-the-art capabilities are inadequat...
Information and communication technology (ICT), information infrastructure (II), geographic information system (GIS), and spatial data infrastructure (SDI) have interdependences. However, there has not been systematic exploration of their dependences, and therefore the nature of their relationships is not precisely known. Here, we use the “Bermuda” metaphor to initiate the discussion on which o...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
gilles fauconnier and mark turner have considered the issue of conceptual metaphor as a special case of more general and comprehensive matter. this vast matter is the analysis of mind system mechanism when it exposes to conceptual domains. to describe such a process, fauconnier and turner use the term of mental or conceptual space. they believe that in order to understand much of human thought ...
