Preparing for the energy crisis, many research and development are underway to reduce the energy consumption and consume the energy more efficiently. BEMS (Building Energy Management System) is one of the essential technologies for saving the energy in the field of building. Commonly, existing BEMS is operated and controlled by the system operators or energy experts manually and also provides limited...
Goal of this paper is to determine actual trends in geocontext extraction methods and to understand which types of geocontext information are the most interesting for users. For this purposes comparison of recent researches about geocontext analysis was done. Researches were compared by the type of achieved result, used formalism, source data and limitations. As the main result of comparison new approach...
Energy efficient building refers to building with an integrated system that is aware toward energy usage and has an effort to automatically reduce all electrical energy wasting by turning some unused devices off. In order to decide an appropriate decision, such a system needs surrounding contexts, such as location and activity that are obtained from sensors around the environment. We propose a novel...
The article presents a case study of applying data cleansing methods and segmentation procedures in order to correct and enhance the structure of the domain corpus of fire service. During the study we present our approach and the results in the task of correcting the misspellings, as well as the method of segmenting the corpus into sentences.
This paper presents a new approach to multi-robot environment exploration based on label maps building through recognition of frontiers. At first, the model of multi-robot environment exploration is built and analysed, in which, the label map building, the formation and role modeling, and the task assignment are synthetically considered. Then the behavior coordination towards exploration process is...
The research question of this study is: How Integration Readiness Level (IRL) metrics can be understood and realized in the domain of border control information systems. The study address to the IRL metrics and their definition, criteria, references, and questionnaires for validation of border control information systems in case of the shared maritime situational awareness system. The target of study...
Learning how to think critically, analyze sources, and develop an evidence-based account is central to learning history. Often, learners struggle to understand inquiry, to apply it in specific scenarios, and to remain engaged while learning it. This paper discusses preliminary design of a mobile AR system that explicitly teaches inquiry strategies for historical sources and engages students to practice...
Recent technological developments can provide technical assistance to support disabled people in their everyday tasks and improve their quality of life. This paper presents the results of preliminary experiments focused on the design of a software-based system for assisting visually impaired individuals Saudi Arabia. The proposed system will help these users in experiencing safer and yet independent...
In this paper the problem of discovering a Petri net (PN) from sampled events sequences representing the execution of industrial or business processes is addressed A method for building a 1-bounded PN from a single event sequence S composed of numerous execution traces is presented; it is based on determining causal and concurrency relations between tasks. A technique for computing the t-invariants...
In recent years, the study of norm-regulated multi-agent systems (MAS) has attracted a lot of attention. The Kanger-Lindahl theory of normative positions has great potential of serving as the logical foundation for normative systems for MAS, but its generality, which allows for great freedom when interpreting the theory, may also become a challenge for practical applications. As an important step...
The objective of this paper was to develop an immersive Web-based learning model to assure the quality of learning through the flipped classrooms. The proposed model was guided theoretically by the flipped classroom as a new Web-based learning trend. It was also guided pedagogically by active and reflective learning principles that support transforming the teaching and learning practices from content...
Classical process discovery approaches usually investigate logs generated by processes in order to mine and discovery corresponding process schemas. When the collaboration processes case is addressed, such approaches turn to be poorly effective, due to the fact that: (i) logs of collaboration processes are usually stored in heterogenous data storages which also expose different data types; (ii) it...
Communities of Practice (CoPs) are groups of experts who share a common interest or topic and collectively want to deepen their knowledge. The use of CoPs is one of the practices that agile practitioner literature suggests for knowledge sharing and coordination in large-scale agile software development. Even though CoPs are largely used and studied in other industrial contexts, their usage in industrial...
The paper presents a method of dynamic composition of interactive augmented reality (AR) scenes based on distributed data sources and depending on the context. For this purpose, a novel declarative language for modelling ubiquitous, contextual AR environments is employed. The language, called CARL - Contextual Augmented Reality Language, enables modularisation of the structure of AR scenes and the...
In the current web, end-users' involvement on creating content for the modern web applications and participation on tailoring their own web applications is increasing. These applications are often called Personalized Web Tasks. Thus, in addition to software developers, end-users are now participating in the service development through personal service configurations. End-user driven development poses...
Formal Concept Analysis is a theoretical framework which structures a set of objects described by properties. Formal Concept Analysis is a classification technique that takes data sets of objects and their attributes, and extracts relations between these objects according to the attributes they share. This structure reveals and categorizes commonalities and variability in a canonical form. From this...
Initiatives to use, in single or hybrid configurations, solar collectors, photovoltaic panels and wind turbines require an approach of such technologies as an integral part of the organic whole of the built environment, in which quality, in their objective or subjective aspects, includes a range of specific social-environment variables. These variables must be deeply associated with the equipment...
Randomized coordinate descent (RCD), attractive for its robustness and ability to cope with large scale problems, is here investigated for the first time in an adaptive context. We present an RCD adaptive algorithm for finding sparse least-squares solutions to linear systems, in particular for FIR channel identification. The algorithm has low and tunable complexity and, as a special feature, adapts...
Service-oriented architecture (SOA) is realized by independent, standardized, and self-describing units known as services. This architecture has been widely used and verified for automatic, dynamic, and self-configuring distributed systems such as in building automation. This paper presents a building automation system adopting SOA paradigm with devices implemented by device profile for web service...
Integration of distributed information systems, autonomous and in real time, heterogeneous and auto adaptable to the context. Thos impact can resolve many problems in different system based on SOA and web services. In this paper, we are interested in defining an approach to provide the different needs of a self-adaptability of SOA to context based on workflow, define the real time goal in our approach...
