During the last few decades, significant changes have been made in the area of building construction and management, especially regarding climate control and energy conservation. A significant turning point was reached in the early 70s with the oil crisis driving a movement for airtight buildings to minimize energy consumption. Unfortunately this turn resulted in a significant deterioration of ...

This work presents a design and implementation an information system called LoRa-Building Energy Management System (Lo-BEMS). research proposes engaging data transmission (read write), that combines the HTTP MQTT protocols using third party broker has monitor control features for energy usages. Data retrieving uses single LoRa modulation delivery to Application Programming Interface (API) in La...

The water–energy–food (WEF) nexus approach is gaining attention due to the challenge of better managing natural elements. Agro-industrial companies, given their environmental impacts, need take sustainability into proper account. However, this sector lacks novel tools needed integrate current methodologies with additional quality frameworks, such as business excellence models (BEMs). Therefore,...

Simulating wave propagation in 3D configurations is becoming a very active area of research. Themain advantage of the BEM is that only the domain boundaries are discretized. As a result, thismethod is well suited to dealing with unbounded domains. However, the standard BEM leadsto fully-populated matrices, which results in high computational costs in CPU time and mem-ory require...

The analysis of seismic wave propagation and amplification in complex geological structures requires efficient numerical methods. In this article, following up on recent studies devoted to the formulation, implementation and evaluation of 3D singleand multi-region elastodynamic fast multipole boundary element methods (FM-BEMs), a simple preconditioning strategy is proposed. Its efficiency is de...

The fact that the information can be collected not only by the government and power companies but also individual users adds seriousness to the problem. In this paper examined this issue by focusing on the load management system based on BEMS that uses the privacy policy-based protection system in the smart grid environment. The structure of the privacy policy-based protection system using load...

Recently, BEMS(Building Energy Management System) are emerging in the field of energy savings. Energy management approaches for Unmanned Building often become unreliable in complex building controls due to False detection, lighting changes, and other factors. We present a new framework to robustly and efficiently to detect people staying and going out based on background subtraction and foregro...
