OPTIMIZATION-BASED MONITORING-SUPPORTED CALIBRATION OF A THERMAL PERFORMANCE SIMULATION MODEL

Building performance simulation is being increasingly deployed beyond the building design phase to support efficient building operation. Specifically, the predictive feature of the simulation-assisted building systems control strategy provides distinct advantages in view of building systems with high latency and inertia. Such advantages can be exploited only if model predictions can be relied u...

Communication Strategies Revisited: Looking beyond Interactional and Psycholinguistic Perspectives

Second language (L2) communication strategies (CSs) have traditionally been dealt with through either interactional or psychological perspectives. However, this paper is a critical attempt to question the status of the particular kinds of psycholinguistic and interactional approaches that currently dominate the field of second language acquisition (SLA). In this way, it expands the significance...

High-Fidelity FEA Simulation through Linking with Experiment Data: A Neural Network Methodology

This paper proposes a novel computational framework for improving realism and fidelity of finite element analysis simulations through experimental test data. The proposed scheme utilizes an artificial neural network to learn and compensate for the differences between a finite element analysis model simulation and corresponding experiment. The proposed computational methodology is poised to sign...

Deep Multi-fidelity Gaussian Processes

We develop a novel multi-fidelity framework that goes far beyond the classical AR(1) Co-kriging scheme of Kennedy and O’Hagan (2000). Our method can handle general discontinuous cross-correlations among systems with different levels of fidelity. A combination of multi-fidelity Gaussian Processes (AR(1) Co-kriging) and deep neural networks enables us to construct a method that is immune to disco...

Quantum phase transitions and quantum fidelity in free fermion graphs

In this paper we analyze the ground state phase diagram of a class of fermionic Hamiltonians by looking at the fidelity of ground states corresponding to slightly different Hamiltonian parameters. The Hamiltonians under investigation can be considered as the variable range generalization of the fermionic Hamiltonian obtained by the Jordan-Wigner transformation of the XY spin-chain in a transver...
