Comparison of predictions from a ray tracing microcellular model with narrowband measurements [PDF]
, 1997 In this paper predictions from a 3-D 'image-based' ray tracing model for microcellular environments are compared with three sets of narrowband measurements performed in a typical urban area. The comparisons illustrate that good agreement can be obtained,

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Adaptive Building Envelope Structures
CONECT. International Scientific Conference of Environmental and Climate TechnologiesClimate changes which are increasing year by year are impacting not our environment but also our daily lives. One of the problems is the emission of greenhouse gases which are produced by householdings using heating fuel. Buildings in the Europe Union represents for 40% of energy consumption and 36% of greenhouse gas emissions.

An evaluation of the hygrothermal performance of 'standard' and 'as built' construction details using steadystate and transient modelling [PDF]
, 2005 Accurate assessment of both surface and interstitial condensation risk at the design stage of buildings is of great importance - not just to minimise the damaging effects moisture can cause to building envelopes, but also to contribute to the provision ...

Advanced Engineering Materials, EarlyView.The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Performance of Retro-Reflective Building Envelope Materials with Fixed Glass Beads
Applied Sciences, 2019 Urban heat islands (UHI) are growing in size and intensity, which is partly attributable to the large amount of anthropogenic waste heat. Moreover, heat emitted from building exterior walls accounts for a large portion of the total anthropogenic waste ...

Comparative Analysis of Energy Demand and CO2 Emissions on Different Typologies of Residential Buildings in Europe [PDF]
, 2019 The building sector accounts for one third of the global energy consumption and it is expected to grow in the next decades. This evidence leads researchers, engineers and architects to develop innovative technologies based on renewable energies and to ...
