Recent works in the boundary element method (BEM) community have been devoted to derivation of fast techniques perform matrix-vector product needed iterative solver. Fast BEMs are now very mature. However, it has shown that number iterations can significantly hinder overall efficiency BEMs. The robust preconditioners is inevitable increase size problems be considered. Analytical offer a interes...

Energy consumption in buildings represents approximately one-third of total energy produced globally. Towards efforts to reduce energy consumption of buildings while also improving its operational efficiency, building controls based on the Multi-Agent Systems (MAS) paradigm have been proposed and developed for use in building operations due to its key features such as learning and adaptation. T...

This research is focusing on the implementation of an Information System (IS), more specifically a building energy management system (BEMS) within several organisations. One of the EU’s 7 Framework Programme’s (FP7) objectives is to “transform the current fossil fuel based energy system into a more sustainable one combined with enhanced energy efficiency (EE)”. This research is concerned with t...

In electroencephalographic (EEG) source imaging as well as in transcranial current stimulation (TCS), it is common to model the head using either three-shell boundary element (BEM) or more accurate finite element (FEM) volume conductor models. Since building FEMs is computationally demanding and labor intensive, they are often extensively reused as templates even for subjects with mismatching a...

The construction of geometry models of heart-torso is critical for solving the forward and inverse problems of magnetoand electro-cardiography (MCG/ECG). Boundary element method (BEM) is a commonly used numerical approach for the solution of these problems and it requires the modeling of interfaces between various tissue regions. In this study, a new BEM (h-adaptive type) has been applied to th...

The concept of sustainability has gained importance over the last years and organizations worldwide are trying to adapt their strategies economic, environmental, social goals in order achieve what is called corporate sustainability. Despite its organizations, there no universally accepted approach for implementing measuring Business Excellence Models (BEMs) widely used all world as a means achi...

This article is mainly devoted to a review on fast BEMs for elastodynamics, with particular attention on time-harmonic fast multipole methods (FMMs). It also includes original results that complete a very recent study on the FMM for elastodynamic problems in semi-infinite media. The main concepts underlying fast elastodynamic BEMs and the kernel-dependent elastodynamic FM-BEM based on the diago...

Accurate geometrical models of the head are necessary for solving the forward and inverse problems of magneto- and electro-encephalography (MEG/EEG). Boundary element methods (BEMs) require a geometrical model describing the interfaces between different tissue types. Classically, head models with a nested volume topology have been used. In this paper, we demonstrate how this constraint can be r...

The practice of validation and uncertainty analysis (UA) building energy models (BEM) is critically reviewed. background for this review the recognized need improvement accuracy in prediction performance, e.g. as part an efficient mitigation response to climate change. was performed using benchmark comparison verification (V&V) frameworks obtained from field scientific computing. First, current...
