Traditional approaches to simulate airflow movements in buildings are computationally expensive and do not achieve real-time prediction of results. This paper discusses an Adaptive Localization Method (ALM) that significantly minimizes the simulation domain to achieve close to real-time predictions. As the user interacts with the space by modifying boundary(More)
Adapting legacy applications for use in a modern heterogeneous environment is a serious challenge for an industrial software vendor (ISV). The adaptation of the NUMECA FINE/Turbo computational fluid dynamics (CFD) solver for accelerated CPU/GPU execution is presented. An incremental instrumentation with OpenACC directives has been used to obtain a global(More)
We establish nearly optimal rates of convergence to self-similar solutions of Smolu-chowski's coagulation equation with kernels K = 2, x + y, and xy. The method is a simple analogue of the Berry-Esséen theorems in classical probability and requires minimal assumptions on the initial data, namely that of an extra finite moment condition. For each kernel it(More)
This paper presents the development and implementation of an Energy-based Decision Support System (EDSS) that will enhance the selection process of replacement building features. EDSS includes dynamic databases that utilize data/web mining concepts, Knowledge Base System (KBS) and a thermal simulation engine. The system allows decisions to be made based on(More)
This paper discusses a framework for integrated Augmented Reality (AR) architecture for indoor thermal performance data visualization that utilizes a mobile robot to generate environment maps. It consists of three modules: robot mapping, Computational Fluid Dynamics (CFD) simulation, and AR visualization. The robot mapping module enables the modelling of(More)
Communications between buildings and their occupants through multimodal Human Computer Interactions (HCI) can dramatically enhance the way buildings are experienced. Although building performance data is becoming more readily available, no research has been established to enable visualization of and interaction with this information in a robust way. This(More)
1.0 ABSTRACT Dynamic data visualization in real-time involves rapid simulations of computerized models. Although computing power has increased exponentially in the last few decades, detailed simulations using software introduce time-delay that defeat the notion of real-time data visualization of the generated results. Approximate techniques can pave way for(More)
