Building information modelling promises model-based collaboration between stakeholders in the project design stage. However, data exchange between physical and analytical building models used for architectural design and structural analysis respectively rarely takes place due to numerous differences in building element representation, especially the representation of geometry. This paper presents the realization of a novel data exchange framework between architectural design and structural analysis building models, based on open interpretations on central storage. The exchange is achieved with a new system architecture, where the program redDim was developed to perform the interpretations, including the most challenging transformations of geometry. We deliver a proof of concept for the novel framework with a prototype building model and verify it on two further building models. Results show that structural-analysis models can be correctly automatically created by reducing dimensionality and reconnecting building elements. The proposed data exchange provides a base for missing standardization of interpretations, which facilitates the non-proprietary automated conversion between physical and analytical models. This research fills the gap in the existing model-based communication that could lead to a seamless data exchange.

The heterogeneity of the architecture, engineering and construction (AEC) industry reflects on digital building models, which differ across domains and planning phases. Data exchange between architectural design and structural analysis models poses a particular challenge because of dramatically different representations of building elements. Existing software tools and standards have not been able to deal with these differences. The research on inter-domain building information modelling (BIM) frameworks does not consider the geometry interpretations for data exchange. Analysis of geometry interpretations is mostly project-specific and is seldom reflected in general data exchange frameworks. By defining a data exchange framework that engages with varying requirements and representations of architectural design and structural analysis in terms of geometry, which is open to other domains, we aim to close the identified gap. Existing classification systems in software tools and standards were reviewed in order to understand architectural design and structural analysis representations and to identify the relationships between them. Following the analysis, a novel data management framework based on classification, interpretation and automation was proposed, implemented and tested. Classification is a model specification including domain-specific terms and relationships between them. Interpretations consist of inter-domain procedures necessary to generate domain-specific models from a provided model. Automation represents the connection between open domain-specific models and proprietary models in software tools. Practical implementation with a test case demonstrated a possible realization of the proposed framework. The innovative contribution of the research is a novel framework based on the system of open domain-specific classifications and procedures for the inter-domain interpretation, which can prepare domain-specific models on central storage. The main benefit is a centrally prepared domain-specific model, relieving software developers from so-far-unsuccessful implementation of complex inter-domain interpretations in each software tool, and providing end users with control over the data exchange. Although the framework is based on the exchange between architectural design and structural analysis, the proposed central data management framework can be used for other exchange processes involving different model representations.

Abstract: This research tackles essential elements of Syrian state-building processes through a structural analysis incorporating several theories and concepts including but not limited to colonialism, nationalism, military interventions, institutional development, minority rule, and eventually neocolonialism. The article reveals how minority rule and different implications of military interventions shaped today’s Syria, as well as addresses some of the current issues such as the absence of domestic political consolidation. The primary aim of this research is to contextualize the role of France—as a former colonizer, within the state-building process of Syria by examining different phases of Syria’s historical past. An examination of Syria’s political developments proved that having inherited a colonial past, the current state of Syria has also inherited an unavoidable legacy of political instability from its colonial past. Keywords: Syria, Middle East, State-Building, Colonialism, Military Interventions.

Objective: The primary aim of this study was to summarize the current state-of-science for principles and practices of intervention in acquired pediatric aphasia (APA). A secondary aim was to identify gaps in research regarding interventional frameworks, and to identify key areas of future inquiry to optimize language outcomes. Conclusions: Although epidemiologic data indicate rising incidence in  APA, limited research on recovery and intervention exists. Results suggest that language intervention supports aphasia recovery; however, available data lack adequate description of methodologies to make crosscomparisons and dosage recommendations possible. Evidence from observational studies suggests that a) pediatric recovery is not necessarily more rapid nor complete than adult recovery; b) principles of neuroplasticity may be applied to pediatric aphasia; however prognostication may be affected by developmental stage and presence of immature language networks; and, c) aphasia symptoms related to literacy may extend into adulthood, even after functional communication has been established. Clinical implications as well as recommendations for research are discussed in light of evidence.

The study examines the current state of implementation of the UN Convention on the Rights of People with Disabilites (CRPD) with regard to the inclusion of children with special needs in mainstream schools in the German states. It provides a comprehensive structural analysis of this area. Article 24 of the convention obliges the signatory states to guarantee an inclusive education system at all levels. In order to examine the extent to which the German states (Länder) implement this requirement in law and practice in their school systems, empirically measurable indicators were formed on the basis of the provisions of the CRPD. Even more than 10 years after ratification of the CRPD, the majority of the German states still face major challenges. Only a few German states are currently undergoing a process of transformation, which is why the majority of children and young people with special educational needs continue to be trained in special and segregated structures.

The aim of this paper is the analysis of the contemporary state of implementation of artificial intelligence in the area of unmanned aerial vehicles (UAV), and a proposal of further use of artificial intelligence systems in this area in the future. We analyse three essential areas in which artificial intelligence systems are currently being implemented to some extend – path following, object detection and tracking, and anti—collision systems. In each mentioned area we apply different solution methods, technical requirements, but also advantages and disadvantages of those solutions. We present an overview of artificial intelligence as a scientific branch. Finally, we present an overview of how artificial intelligence in the field of UAV could be implemented in the future, based on an analysis of the current state and direction of research and development in the present. We describe the possibilities of use artificial intelligence systems in two areas that are currently receiving the most attention at concept level, namely the flight of autonomous UAV swarms and the improvement of communication and data exchange between individual UAVs using artificial intelligence.

This paper describes an initial study towards characterizing model associativity gaps and other engineering interoperability problems. Drawing on over a decade of X-analysis integration (XAI) research and development, it uses the XAI multirepresentation architecture (MRA) as a means to decompose the problem and guide identification of potential key metrics. A few such metrics are highlighted from the aerospace industry. These include number of structural analysis users, number of analysis templates, and identification of computing environment components (e.g., number of CAD and CAE tools used in an example aerospace electronics design environment). One problem, denoted the fine-grained associativity gap, is highlighted in particular. Today such a gap in the CAD-CAE arena typically requires manual effort to connect an attribute in a design model (CAD) with attributes in one of its analysis models (CAE). This paper estimates that 1 million such gaps exist in the structural analysis of a complex product like an airframe. The labor cost alone to manually maintain such gaps likely runs in the tens of millions of dollars. Other associativity gap costs have yet to be estimated, including overand underdesign, lack of knowledge capture, and inconsistencies. Narrowing in on fundamental gaps like fine-grained associativity helps both to characterize the cost of today’s problems and to identify basic solution needs. Other studies are recommended to explore such facets further.
