Integration of an energy– economy model with an urban energy model

open access: yesBuildings and Cities, 2021
A proliferation of energy models has been developed across disciplines to explore energy and greenhouse gas (GHG) emissions-reduction strategies in cities. Hybrid models are especially useful because they incorporate more dynamics to simulate realistic results informed by relevant high-level policy decisions and building-level factors.

Aging in the Random Energy Model [PDF]

open access: yesPhysical Review Letters, 2002
In this letter we announce rigorous results on the phenomenon of aging in the Glauber dynamics of the random energy model and their relation to Bouchaud's 'REM-like' trap model. We show that, below the critical temperature, if we consider a time-scale that diverges with the system size in such a way that equilibrium is almost, but not quite reached on ...

Modeling the Energy Performance of LoRaWAN [PDF]

open access: yesSensors, 2017
LoRaWAN is a flagship Low-Power Wide Area Network (LPWAN) technology that has highly attracted much attention from the community in recent years. Many LoRaWAN end-devices, such as sensors or actuators, are expected not to be powered by the electricity grid; therefore, it is crucial to investigate the energy consumption of LoRaWAN.

Energy Models in the Loop

open access: yesProcedia Computer Science, 2018
Abstract For transiently powered systems a reliable power management is essential. Power management methods in software allow for run-time decisions about the utilization of system resources based on energy models, performance counters and sensor readings.

N=2 supersymmetry partial breaking and tadpole anomaly

open access: yesNuclear Physics B, 2015
We consider the U(1)n extension of the effective N=2 supersymmetric U(1)×U(1) model of arXiv:1204.2141; and study the explicit relationship between partial breaking of N=2 supersymmetry constraint and D3 brane tadpole anomaly of type IIB string on Calabi–

Experimental Energy and Exergy Analysis of an Automotive Turbocharger Using a Novel Power-Based Approach

open access: yesEnergies, 2021
The performance of turbochargers is heavily influenced by heat transfer. Conventional investigations are commonly performed under adiabatic assumptions and are based on the first law of thermodynamics, which is insufficient for perceiving the ...

Designing Unknown Input Observers for Fault Reconstruction in Disturbed Takagi-Sugeno Fuzzy Systems

open access: yesEngineering Proceedings, 2023
Fault occurrence in practical systems, if not addressed, can cause diminished performance or even system breakdown. Therefore, fault detection has emerged as a crucial challenge in ensuring system safety and reliability. This paper presents a novel fuzzy
