Boundary-element methods (BEMs) for solving integral equations numerically have been used in many fields to compute the induced charges at dielectric boundaries. In this paper, we consider a more accurate implementation of BEM in the context of ions in aqueous solution near proteins, but our results are applicable more generally. The ions that modulate protein function are often within a few an...

Recently, building automation system (BAS) and energy management (BEMS) technologies have been applied to efficiently reduce the consumption of buildings. In addition, studies on utilizing large quantities data actively conducted using artificial intelligence machine learning. However, high cost installation difficulties limit use measuring devices sense indoor environment all Therefore, this s...

In this paper, we introduce a flexible box erecting machine (BEM) that swiftly and automatically transforms cardboard into a three dimensional box. Recently, the parcel service and home-shopping industries have grown rapidly, and there is an increasing need for various box types to ship various products. However, workers cannot fold thousands of boxes manually in a day. As such, automatic BEMs ...

This communication summarizes recent investigations on the identification of defects (cavities, inclusions) of unknown geometry and topology by means of the concept of topological sensitivity. This approach leads to the fast computation (equivalent to performing a few direct solutions), by means of ordinary numerical solution methods such as the BEM (used here), the FEM or the FDM, of defect in...

Abstract: The current Building Energy Performance Simulation (BEPS) tools are based on first principles. For the correct use of BEPS tools, simulationists should have an in-depth understanding of building physics, numerical methods, control logics of building systems, etc. However, it takes significant time and effort to develop a first principles-based simulation model for existing buildings—m...

<p>Building energy management systems (BEMS) are critical tools for managing and controlling a facility's technical services, such as lighting, ventilation, heating, air conditioning, to ensure that the building operates at peak efficiency while decreasing waste. The Mabini Building De La Salle Lipa has nearly hundred rooms, 70 of which used by college students lecture laboratory classes....

The thermal inertia of a building envelope endows with heat storage capability, introducing scheduling flexibility to energy microgrid (BEM). is usually modelled as virtual (VES) and used optimize the operation BEMs reduce electricity costs. However, VES capacity impacted by varies variations in indoor/outdoor temperature. If only envelope's effect on transfer considered, without proper quantif...

The Lighthill's wave equation provides an accurate characterization of the hydrodynamic noise due to interaction between a turbulent flow and obstacle, that is needed get in many industrial applications. In present study, solve expressed as boundary integral equation, we develop efficient numerical method determine three-dimensional Green's function Helmholtz presence obstacle arbitrary shape, ...

The miombo woodland is the most extensive dry forest in the world, with the potential to store substantial amounts of biomass carbon. Efforts to obtain accurate estimates of carbon stocks in the miombo woodlands are limited by a general lack of biomass estimation models (BEMs). This study aimed to evaluate the accuracy of most commonly employed allometric models for estimating aboveground bioma...

We bring together time series data on trade, production, and input-use to compute the value added content of trade over the past four decades (1970-2009). Comparing the ratio of value added to gross exports, we measure changes in production fragmentation for the world as a whole, individual countries, and bilateral trade partners. For the world, the share of value added in trade falls by 10 to ...
