Deterrence, preparedness, and response to evolving chemical, biological, radiological, and nuclear CBRN threats are being strengthened by international communities and states. These threats require closer top-down and bottom-up cooperation at all levels in order to enable collaborative shared efforts, foster an environment for learning from one another, pool resources and expertise, and take advantage of synergies with an ultimate objective of improving institutional and collective safety and security. Improving preparedness and response necessitates closer and stronger interactions among various stakeholders, including security practitioners, researchers, policy makers, innovation providers, small
and medium-sized enterprises (SMEs), and industry. In this context, forging a dynamic multidisciplinary CBRN network could be a more effective approach to promote synergies and addressing the need for stronger cooperation. A resource pooling strategy helps build a highly cooperative CBRN stakeholder community and ensures the network’s
long-term viability and sustainability. This study examines practical methods to ensure sustainability in pooling and sharing resources, knowledge, and best practices in the field of CBRN training and capacity building. It details how a solution-oriented strategy was created, including a generalised method for combining resources and maximising institutional and government investments. This study was conducted by combining the results of a literature review on best practices in resource pooling and sharing, determining its applicability to CBRN defence, and examining the Horizon 2020 project, European Network of CBRN Training Centres (eNOTICE), as a case study to draw real-time input from the project activities. This work proposes a novel and strategic contribution to the field of CBRN defence in the form of a practice-oriented concept and methodology, for establishing and maintaining CBRN networks at local, regional, and global levels. This top-down and bottom-up transversal strategy offers a way forward that can help CBRNrelated dynamic interdisciplinary networks to establish, maintain, and develop in a
sustainable way.

Semantic-level multimodal integration of video and speech data streams Olga Vybornova Universite Catholique de Louvain Hildeberto Mendon¸ ca Universite Catholique de Louvain Benoit Macq Universite Catholique de Louvain Abstract: A method of multimodal multi-level fusion integrating contextual information obtained from spoken input and visual scene analysis is defined and developed in this research. The resulting experimental application poses a few major challenges: the system has to process unrestricted natural language, free human behaviour, and to manage data from two persons in their home/office environment. The application employs various integrated components: speech recognition, person identification, syntactic parsing, NL semantic analysis, image processing, human behavior analysis, the domain ontology and the decision-making engine. In our approach the high level fusion of input streams is performed in three stages: (i) early fusion that merges information at the recognitio...

Deployment of an on-site laboratory to contain an expanding outbreak and protect public health through rapid diagnosis of infected patients and identification of their contacts is a challenging and complex response, further complicated by time limitation and dramatic consequences of failure. Effective operations management and decision-making are critical for a successful Fieldable Laboratory (FL) mission at each phase of the mission. To analyze the principles and challenges of the operations management and associated decision-making process, the FL mission has been broken down into five successive interlinked phases defined as the “FL mission cycle” (FL-MC). Each phase comprises a set of operational functions (OFs) corresponding to the mission activities. Some decisions are associated with a single OF, whereas others are taken across different OFs and FL-MC phases. All decisions are treated as logical entities inherently linked to each other and to the whole situational context wit...

In the case of rapid outbreaks of infectious diseases in remote locations, the lack of real-time information from the field and rapid spread of misinformation can be a major issue. To improve situational awareness and decision-making at all levels of operational deployment, there is an urgent need for accurate, reliable, and timely results from patients from the affected area. This requires a robust and fast channel of communication connecting first responders on-site, crisis managers, decision-makers, and the institutions involved in the survey of the crisis at national, regional, and international levels. This has been the rationale sustaining the development of advanced communication tools in the Biological Light Fieldable Laboratory for Emergencies (B-LiFE). The benefit of terrestrial (TETRA, LTE, 5G, and Wi-Fi-Fi) and SatCom communications is illustrated through a series of missions and exercises conducted in the previous five years.

Effective coordination and information sharing are vital for the response to sudden onset disasters, and aim at em¬powering the responding organizations as well as the affected commu¬nities to respond to and recover from the impact of a disas¬ter in a well-orchestrated manner. The response to Typhoon Haiyan, however, revealed many organizational and tech¬nical obstacles that impeded the efficient sharing and re¬trieval of information or alignment of operations. This paper presents findings from field research that was conducted in the Philippines in De-cember 2013, and outlines approaches centered around decision-makers’ information needs to direct future work on standardization and information sharing

This paper presents a knowledge-based method of early-stage high level multimodal fusion of data obtained from speech input and visual scene. The ultimate goal is to develop a human-computer multimodal interface to assist elderly people living alone at home to perform their daily activities, and to support their active ageing and social cohesion. Crucial for multimodal high level fusion and successful communication is the provision of extensive semantics and contextual information from spoken language understanding. To address this we propose to extract natural language semantic representations and map them onto the restricted domain ontology. This information is then processed for multimodal reference resolution together with visual scene input. To make our approach flexible and widely applicable, a priori situational knowledge, modalities and the fusion process are modelled in the ontology expressing the domain constraints. Here, we illustrate ontology-based multimodal fusion on a...

User Profiling in Assistive Interface for Aged People Cognitive Assessment, Stimulation and Training Olga Vybornova Institute for Systems Analysis, Russian Academy of Sciences (ISA RAS) Abstract: Development of an interface aimed at elderly people assistance in their everyday activities and support of their independent life and social contacts, as well as at cognitive assessment, stimulation, training and rehabilitation, needs a detailed user profile. The user profile in the form of an ontology makes the knowledge base for individual communication, providing all the information about the users collected in advance and updatable in the course of interaction, making the interface personalized, attractive and usable for each particular person. In the presented work the ontology manages the application metadata describing the user’s socio-demographic data, living conditions, psycho-social well-being, social contacts, state of physical health and cognitive abilities qualitative assessmen...

The present document has been prepared in the framework of the FP7-SEC 2007-2013 PRACTICE project as an UCL-CTMA deliverable reporting on the activities funded under PRACTICE and as a preparation for the mission executed by UCL-CTMA with support of the Belgian Ministry of Defence for PRACTICE Demo-exercise PIONEX in Pionki, Poland, in April 2014. Description of work includes development of a tool that aims at bringing to the field a laboratory field station allowing execution of high performance identification tests. One of the main issues here is to maximize rapid deployment under the constraint of a limited budget. As a consequence the option selected by the UCL consists in minimizing the size and the weight of the laboratory components.

Fast on-scene deployment of an analytical laboratory capacity to help contain an outbreak of infectious disease requires set-ting up an appropriate policy framework and a range of operating procedures to ensure efficient support to decision-making, as well as the optimal engagement and use of dedicated resources. This work focuses on fully autonomous deployment when the mobile capacity operators themselves need to make decisions and implement all the operational functions (OFs), from basic needs like provision of equipment, power supply, food and accommodation for the staff, to complicated procedures like logistics of transportation and supply chain. A model of the identity and structure of specific decision-making requirements for a generic deployment of laboratory capacities was built from the real experience during specific deployments of the operators and managers of the Belgian capacity Biological Light Fieldable Laboratory for Emergencies (B-LiFE). Self- and external assessments were conducted and lessons learned successively reviewed after each deployment by B-LiFE labora-tory operators and managers and observers in the framework of European demonstration projects and joint exercises. The result was consolidated by integrating the assessment of European Commission-appointed certifiers during the certification procedure of B-LIFE as a self-sufficient module of the European Medical Corps, namely the European modules exercise “Modex” in April 2017 (Revinge, Sweden) followed by the “ModTTX 4” Table-top in May 2017 (Bruges, Belgium). A complete and updated set of Fieldable Laboratory operational functions is presented, including their contents, cross-links, inter-dependencies, information needs for implementation, and related decisions.

Application overview We present a method for knowledge-based context sharing within multimodal high level fusion integrating data obtained from spoken input and visual scene analysis. The goal of our work is to develop a multimodal interface as an "intelligent diary" to proactively assist elderly people living alone at home to perform their daily activities, to prolong their safe and secure personal autonomy, to support their active ageing and social cohesion. To provide natural interaction with the user(s) a system must be able to comprehend the fully coordinated mind-and-body behavior, to handle semantic-level input data fusion, i.e. to combine information arriving simultaneously from different modalities into one or several unified and coherent representations of the user's intention. Our context-aware user-centered application should accept spontaneous multimodal input – English speech, 3D gestures (pointing, iconic, possibly metaphoric) and user's physical act...

Improved information collection, interpretation and processing are vitally important for optimized crisis response. A comprehensive information management (IM) system using ontology-based approach is aimed to handle heterogeneous information and to model the operational domain knowledge associated with the deployment of a light fieldable laboratory (LFL) during the recent Ebola crisis in Guinea. This LFL mission was part of the B-LiFE (Biological Light Fieldable Laboratory for Emergencies) project which integrates analytical and space-based technologies. LFL can be considered as a toolbox where all operational functions and related tools are incorporated into a single information space. An ontology can therefore be applied to facilitate the preparation and management of next LFL missions. The aim is to provide technical compatibility of information shared between tools and to align terminology and definitions while complying with guidelines, best practices and procedures. Accordingly, the LFL domain becomes a formalized and structured modeling of LFL concepts, procedures and functions which, in turn, helps distinguishing functions which are necessary for the mission from those which are incompatible according to a given mission or scenario. Such consistent logical modelling allows then to efficiently plan and configure any LFL mission by selecting and activating in due time, among all available functions and tools, those which are strictly mandatory.

Deployment of an on-site laboratory to contain an expanding outbreak and protect public health through rapid diagnosis of infected patients and identification of their contacts is a challenging and complex response, further complicated by time limitation and dramatic consequences of failure. Effective operations management and decision-making are critical for a successful Fieldable Laboratory (FL) mission at each phase of the mission. To analyze the principles and challenges of the operations management and associated decision-making process, the FL mission has been broken down into five successive interlinked phases defined as the " FL mission cycle " (FL-MC). Each phase comprises a set of operational functions (OFs) corresponding to the mission activities. Some decisions are associated with a single OF, whereas others are taken across different OFs and FL-MC phases. All decisions are treated as logical entities inherently linked to each other and to the whole situational context within the FL operational domain. Being part of the laboratory information management system (LIMS), the FL domain ontology is developed as the main knowledge management tool supporting the decision-making process. This is an essential way to promote interoperability and scalability between different FL modules and health care capacities during cross-border biological crises.
