Accurately predicting industrial electricity consumption is essential for optimizing energy efficiency, and reducing costs in industrial operations. This study presents a novel hybrid prediction model based on radial basis function neural network (RBFNN) and kernelized support vector regression (KSVR) methods (RBFNN-KSVR) for estimating industrial electricity consumption. Key...
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), as the cause of Coronavirus Disease 2019 (COVID-19), may survive in sewage or wastewater treatment plant (WWTP). This condition increases the risks of reusing treated wastewater (TW), particularly in developing countries. We introduced a new index, Viral Risk Index (VRI), for risk classification based on available...
Energy and its related services are crucial to the well-being of society. Access to clean water and sanitation is dependent on energy supply, and so is the provision of quality education and healthcare services. Of equal importance is the manner in which energy is produced and consumed, as the livelihood of future generations depends largely on this. Recently, policymakers have...
This study presents a comprehensive carbon footprint analysis of polypropylene production within an Iranian petrochemical facility, employing a broad scope that encompasses all relevant processes across the entire factory, rather than focusing solely on the polypropylene production unit. Utilizing a life cycle assessment (LCA) approach aligned with ISO standards, the research...
This study aims to design a model for the relationships between the indices of a creative city and creative economy development in the creative city of Rasht, Guilan Province, Iran. In this research, the grounded theory was employed to conduct a qualitative analysis, and semi-structured interviews were carried out for data collection. For this purpose, eight interviews were given...
Virtual power plants (VPPs) have gained significant attention in recent years as a promising solution for optimizing the operation of power systems. VPPs allow for the integration and coordination of Distributed Energy Resources (DERs), such as renewable energy sources, to provide grid support and stabilize the power supply. This paper presents a VPP that utilizes a three-phase...
This study investigates how pulverized wood-derived biochar affects leaching and release behavior of Chromium (Cr), Copper (Cu), and Nickel (Ni) from construction and demolition waste (CDW) towards groundwater. CDW constitutes a large portion of total waste generation in both developed and developing countries, prompting attention due to its substantial volume, resource...
Life cycle assessment (LCA) is a widely recognized tool for environmental assessment, which has experienced a strong development both in methodology and applications. This paper aimed to perform a bibliometric analysis of LCA research during 2000-2022, considering publication types, publication trends, subject categories, journals, institutions, countries, and author keywords...
The sprawling growth of urban settlements is a dominant spatial process in many cities of developing countries. This development's most severe apparent effect is the loss of ecological infrastructure. In this way, consequently, the ecosystem services that have been provided for human settlements for thousands of years will be lost. Urban ecological infrastructure is also very...
In Tehran, Iran's most populous province, there has been a notable surge in livestock production in recent years, prompting a critical examination of water resource allocation through the water footprint indicator. This study uniquely concentrates on livestock productions at a provincial level, specifically within four key counties boasting the highest production rates in Tehran...
Due to rapid development of cities, number of municipal wastewater treatment plants (WWTP) has faced drastic growth in recent decades. Reviewing the literature indicates that WWTPs in urban areas are one of the essential energy consumers, and it is necessary to evaluate their energy consumption. In Tehran, the capital of Iran, the number of WWTPs has increased to meet the demands...
The banking industry is one of the most important pillars of the economy of any country, which plays a decisive role in the economic development and growth of countries due to the provision of various financial and credit services. With the globalization of the banking industry, it is very important to use income diversification strategies to improve value and efficiency. Using...
Encouraging foreign and private sectors to participate in renewable projects in developing countries, which not only experience rapid growth in energy demand but also encounter challenges in financing clean projects, presents a complex issue for their governments. To address this challenge, two contentious issues must be addressed concurrently: 1) accurate long-term valuation of...
Global attention has focused on the general deterioration of water quality due to rapid industrialization, population growth and a steady decline in the amount of safe water available. This study provides a new framework for waste load allocation from an fair and equitable perspective. First, the optimal scenarios are generated by calling the (Streeter-Phelps) S-P equation with...
The rapid growth of urbanization, along with the extensive construction of infrastructure and real estate projects, has resulted in higher rates of Construction and Demolition Waste (C&D waste). This condition, combined with the lack or inefficiency of municipal programs to manage C&D waste, has exacerbated urban issues related to C&D waste collection, transportation, and...
