“…The development cycle of the ES prototype is done according to the incremental model. Such a model is well-suited for expert systems and was previously used in [31][32][33]. In the incremental model, each new version has a new set of rules that gradually extends the knowledge and the functionality of the system (Fig.…”

“…In this way, the ES is a proper approach to perform energy diagnostics in industrial plants and to recommend actions for improving EE and promoting KM. A successful ES application related to EE technology is the design of cogeneration plants [31][32][33] presented a combined rule-based/data mining approach to detect EE anomalies in smart buildings and Faia et al [34] shown an ES combining case-based reasoning and swarm intelligence to determine the potential for energy reduction in buildings.…”

This article presents the application of an expert system (ES) prototype as an intelligent tool for preliminary diagnostics of energy efficiency (EE) potential in Brazilian industrial plants and knowledge management (KM) in organizational environments, aimed especially to small-and medium-sized enterprises. The prototype provides the diagnostics rationale through a module for an explanation to support the decision making and provide insights regarding the adoption of EE actions. The knowledge base required by the prototype is built from the expertise and experience of a group of experts in EE and professionals from the industrial sector. The knowledge acquired from this interaction is represented in the form of rules, which are computationally implemented through a well-known tool for developing ES. Then, the resulting prototype is validated by the same group of multidisciplinary experts. Two different applications are presented to demonstrate the possibilities of EE improvement in industrial plants. These applications also show the ES as a valuable resource for organizational KM. In such a context, the ES creates a permanent corporate memory regarding EE, so that the access to this knowledge is independent on the availability of the human experts in the area. The ES also turns EE expertise into lasting value through sharing and retention actions, contributing to further improvements and processes continuity.

“…Results have shown that emission level is well below the NEQS (National Environmental Quality Standards), Pakistan, level that makes rice husk an environmental-friendly fuel [33]. CO level is high because carbon gets converted to CO as illustrated in (14). Following the optimised parameters mentioned in the parametric study, CO level can be reduced.…”

To control the drastically changing environment, fossil fuels to sustainable resources transition are indispensable. Biomass has huge potential as sustainable power generation fuel, but the detailed investigation is needed to ensure the profitable usage of biomass. The principal aim of this study is to investigate the energy conservation opportunities in a biomassfuelled boiler. An extensive thermodynamics analysis (using energy and exergy mathematical models) of a rice husk-based fixed bed boiler has been conducted. Research has provided measures to optimise the operational parameters of the boiler. Energy and exergy pathways of the boiler have been critically analysed to trace the pivotal cause of losses and irreversibilities in the boiler. A robust parametric study has evaluated the impacts of excess air percentage, stack gas temperature, and stack gas oxygen content on the boiler performance. Cycle tempo software is used to trace the energy losses through the stack gas. Based upon recommended improvements, analysed boiler efficiency can be increased by 3-4% with minimum savings of 150,000 US$/year. It is concluded that rice husk is an environmental-friendly fuel and it has huge potential as sustainable cogeneration fuel. This comprehensive analysis has provided a framework for future studies to analyse the performance of any boiler.

In deep space manned travels, the crew life will be totally dependent on the environment control and life support system of the spacecraft. A life-support system for manned missions is a set of technologies to regenerate the basic life-support elements, such as oxygen and water, which makes resilience a paramount feature of this system. The resilience of a complex engineered system is the ability of the system to withstand failures, continue operating and recover from those failures with minimum disruption. Resilient design is a new design framework on which the main goal is to quantify system resilience upfront in order to guide the design team during the conceptual design stage. In this article, we present a tool that combines a rule-based approach with a Monte Carlo-based approach to evaluate the resilience of a proposed environment control and life support system designed for deep space travel. Based on the results found, we explore a few design alternatives in order to increase system resilience.
