In this paper, we consider the energy-efficient coordination of a set of appliances in a smart-building. We introduce a theoretical formulation of the coordination problem and an Integer Linear Programming model for its resolution. Our formalization is complemented by an analysis of the properties and limits of the model. We also define a practical smart-building setting in which our formalization...
We introduce the Qarnot platform, a new edge computing platform for the design of smart-buildings. Our proposition is based on a new model of servers that also serve as heaters. As a use case, we consider the recognition of acoustic events. We describe a reference architecture for the processing of acoustic flows in the Qarnot platform. We also present some experimental results on the recognition...
In a previous publication by the same authors, a computational design system was described that identifies aesthetical color combinations. In that work the type of color aesthetics pursued was to be determined prior to the design representing a given design objective. Complementing the previous study, in this work, the type of color aesthetics that is most suitable for a given scene at hand is pursued...
In the recent years, the cloud approach to computing has become increasingly popular, in part because it provides location- and device-independent access to applications and data. This feature, in turn, allows to implement a computing system with unified data, in which one's data can be accessed and modified from any device one uses. However, pure cloud computing architectures may be a relatively...
The complexity and diversity of future energy systems will require co-simulation solutions that enable the integration of tools from multiple domains for research and development. We introduce an open-source framework, OpenBuildNet, for distributed co-simulation of large-scale smart energy systems. Using a loose-coupling approach to co-simulate parallel processes, it can leverage and seamlessly integrate...
Chunking has emerged as a basic property of human cognition. Computationally, chunking has been proposed as a process for compressing information also has been identified in neural processes in the brain and used in models of these processes. Our purpose in this paper is to expand understanding of how chunking impacts both learning and performance using the Computational-Unified Learning Model (C-ULM)...
Being a particular structure of ancient architecture in China, a large amount of wooden architectures were inscribed on the World Heritage List. The components can be perceived as the carriers of multivariate information which will increase and update over time in a long term. To strengthen the correlation between digital information and components of architectural entities, and meet the growing demands...
DACCOSIM is a multi-simulation environment for continuous time systems, relying on FMI standard, making easy the design of a multi-simulation graph, and specially developed for multi-core PC clusters, in order to achieve speedup and size up. However, the distribution of the simulation graph remains complex and is still the responsibility of the simulation developer. This paper introduces DACCOSIM...
The architectural design studio could be considered with no doubt as the principal pillar of the architectural education process, and it plays one of the most important roles in developing this process. Regardless of the rise of the use of computing in architecture profession, the main focus -at least in developing countries- is on presentations as compared to other realms of the practice. The current...
Many agent simulations involve computational models of intelligent human behavior. In a variety of cases, these behavior models should be high-fidelity to provide the required realism and credibility. Cognitive architectures may assist the generation of such high-fidelity models as they specify the fixed structure underlying an intelligent cognitive system that does not change over time and across...
In this article, we propose a new behavioral thermal modeling method for fast building performance analysis, which is critical for energy-efficient smart building control and management. The new approach is based on two recurrent neutral network architecture to obtain the compact nonlinear thermal models for complicated building. We start with a more realistic building simulation program, EnergyPlus,...
Enterprise Architecture Modeling (EAM) approaches all use multiple, inter-related views to describe the properties of an enterprise system and its surrounding environment -- that is, they are multi-view specification (MVS) approaches. However, there is still little consensus on how such modeling environments should be realized and on the pros and cons of the different fundamental design choices involved...
Heating, ventilation, and air conditioning (HVAC) systems in large industrial or office buildings are complex systems with many data points that pose enormous challenges to engineering and control. From an engineering viewpoint, the classical, centralized approach of system design has obvious limitations in flexibility regarding later reconfigurations and layout changes during system operation. Moreover,...
Lifecycle and effective dada management has become and still remains a difficult task in architecture, engineering, and construction domain. Recently, the emerging Building Information Modeling (BIM) gains more and more momentum in construction data presenting, processing, and sharing. With precise 3D digital geometry graphs, BIM has the potential to integrate diverse data from construction phases...
With the decreasing Mean Time Between Failures (MTBF) of high performance computing systems, process failure has become a normal phenomenon rather than an exception. The failures in high frequency lead to fault tolerance, a key feature of high performance applications. To provide fault tolerance interfaces for active message programs, this paper proposes a novel model called event-driven fault tolerance...
Performance models offer a convenient tool to assess design alternatives and predict the execution time of distributed simulation (DS) systems at design time, before system implementation. Currently, performance models are to be manually developed and the related extra effort often becomes the limiting factor for their cost- and time-effective use. In this paper, we aim to reduce this extra effort...
Nowadays, Infrastructure as a Service (IaaS) clouds are considered a viable solution for the on-demand provisioning of computational resources. Since its popularization in 2006 by the Amazon Elastic Computing Cloud (EC2), the IaaS paradigm is being adopted by many organizations not only to lease resources from a Cloud provider, but also to implement on-premise IaaS Clouds. The former, and original...
Given the importance of clients in service-oriented computing, and the ongoing evolution of distributed system and application realization technologies from client/service architectures, through distributed-object and service-oriented to cloud computing, there is a growing need to lower the complexities and barriers involved in the development of client applications. These range from large scale business...
When the finite element analysis of masonry structure are conducted by using micro-model, the stress-strain curves of brick and motar are necessary. 20 sintered shale brick prisms, 20 autoclaved lime-sand brick prisms and 40 mixed mortar prisms in axial compression were tested. The stress-strain curves, prism compressive strength, elastic modulus and Poisson's ratio of brick and mortar were obtained...
