Passive Guaranteed Simulation of Analog Audio Circuits: A Port-Hamiltonian Approach

open access: yesApplied Sciences, 2016
We present a method that generates passive-guaranteed stable simulations of analog audio circuits from electronic schematics for real-time issues. On one hand, this method is based on a continuous-time power-balanced state-space representation structured

A Comprehensive Mathematical Model for the Estimation of Solar Radiation and Comparative Analysis in Greenhouses with Two Distinct Geometries and Covering Materials: Case Study in Psachna, Evia, Greece

open access: yesEng
This study calculates the intensity of radiation received by two types of greenhouses: Even Span and Modified Arched geometry. The Even Span greenhouse is covered with glass, while the Modified Arched greenhouse is covered with polyethylene plastic ...

The effects of multiple covers with condensation and optical degradation of a polyethylene windscreen on the performance of a sky cooling system

open access: yesInternational Journal of Sustainable Energy, 2019
This study evaluates the performance of a heat-pipe-augmented sky radiator system modelled using MATLAB. It was developed to simulate thermal networks with the following nodes: polyethylene cover(s), radiator plate with selective surface, heat pipe ...

Design parameters and control strategies for a combined passive heating and cooling system in Louisville, KY

open access: yesInternational Journal of Sustainable Energy, 2019
Conventional passive solar systems can significantly reduce a building's heating load. However, the integration of passive heating and cooling systems in the same building and the benefits of actively controlling passive systems has largely been ...

Towards a passive DNS monitoring system [PDF]

open access: yesProceedings of the 27th Annual ACM Symposium on Applied Computing, 2012
The domain name system (DNS) is a complex distributed database on which several Internet services rely on. As its monitoring is critical, researchers and internet service providers continuously monitor DNS traffic for identifying anomalies, measuring performance, and generating usage statistics.

Parameterized Interpolation of Passive Systems

open access: yesSIAM Journal on Matrix Analysis and Applications
We study the tangential interpolation problem for a passive transfer function in standard state-space form. We derive new interpolation conditions based on the computation of a deflating subspace associated with a selection of spectral zeros of a parameterized para-Hermitian transfer function.
