Abstract: Least cost scheduling of construction projects is obtained by time management with optimum cost which is also termed as crashing. Although papers published in major journals have documented real applications for schedule crashing such as working overtime, working double shifts, adding additional resources, employee productivity, and relaxing activities. The objectives of the paper are to study the algorithms from the previous studies and their impact on the real-life project crashing. And in addition to that the paper discussed the main idea of crashing PERT/CPM network. To achieve such objectives, studies about crashing algorithm/programing, data collection, and PERT/CPM network crashing technique were carefully explored and scrutinized. Suggestions for further research are for preventive actions for nonconformance risk activities may suffer additional cost, and to use this data to create new procedures that incorporate quality concepts into project scheduling difficulties.

Keywords: Least Cost Scheduling, Crashing using algorithms, PERT/CPM network.

Abstract: Vapor Recovery Units (VRUs) are pivotal technologies in the oil refining industry, designed to capture and repurpose volatile organic compounds (VOCs) released during refining operations. These emissions, if left unchecked, can significantly contribute to air pollution and climate change, making VRUs essential for both environmental compliance and corporate responsibility. This paper provides a comprehensive analysis of the operational principles of VRUs, their integration into refinery processes, and their multifaceted benefits.

Keywords:  benefits include Environmental Compliance, Resource Efficiency, Economic Advantages, Corporate Reputation, Future-Proofing Operations.

Abstract: Vapor recovery unit systems (VRU) have become essential in mitigating volatile organic compounds (VOCs) emissions from fueling stations, which are significant contributors to urban air pollution. This paper explores the two main types of vapor recovery systems—Stage I and Stage II—discussing their mechanisms, efficiency, and regulatory landscape across various countries. Real-world examples from the United States, Europe, Canada, and Australia illustrate the practical applications of these systems. The benefits of implementing a VRU, not only enhances the environmental quality but also promotes public health and regulatory compliance. Through a comprehensive analysis, this paper underlines the importance of vapor recovery technologies in achieving a sustainable fuel delivery system.

Keywords: Vapor recovery unit systems (VRU), volatile organic compounds (VOCs), fuel delivery system.

Abstract: The reliance on internal combustion engines (ICEs) powered by fossil fuels has significantly contributed to global environmental challenges, including climate change, air pollution, and public health risks. As the demand for sustainable energy solutions intensifies, alternative fuels have emerged as a pivotal component in reducing harmful emissions and improving energy efficiency in ICEs. This research paper explores the impact of biofuels, hydrogen, electrofuels, and other renewable energy sources on mitigating ICE-related pollution. The study utilizes a systematic review of recent advancements in alternative fuel technologies, supported by case studies of real-world applications. Key findings highlight the significant reduction in greenhouse gas emissions, nitrogen oxides, and particulate matter when using alternative fuels compared to traditional fuels. The paper also discusses challenges such as economic feasibility, infrastructure requirements, and technological limitations, offering insights into potential solutions. By analyzing emission data, technological innovations, and policy implications, this paper underscores the transformative potential of alternative fuels in driving global sustainability.

Abstract: Mechanical engine oil plays a critical role in reducing friction, preventing wear, and managing heat dissipation in internal combustion engines. However, its viscosity—a key property that determines its ability to form a lubricating film—is highly susceptible to elevated temperatures. This paper explores the impact of high temperatures on the viscosity of engine oil, detailing the mechanisms of degradation, consequences for engine performance, and innovative approaches to enhancing oil performance. By analyzing empirical research, the study provides insights into optimizing lubrication systems to meet the demands of modern engines operating under extreme conditions.

Abstract: As the global climate continues to warm, cities face the challenge of higher energy consumption for cooling purposes. One of the most effective and sustainable strategies to reduce this energy use is shading building roofs. This research paper explores different techniques used for shading roofs, including cool roofs, green roofs, and architectural shading. These techniques not only reduce the amount of energy needed to cool buildings but also mitigate the urban heat island (UHI) effect, lower air conditioning costs, and improve thermal comfort. The findings indicate that roof shading is a cost-effective strategy with numerous environmental and economic benefits.

Keywords: shading building roofs, architectural shading, global climate, economic benefits.

Abstract: The braking system is one of the most critical safety components in automobiles. The system's performance largely depends on the frictional interaction between the brake pad and the disc rotor. Dust accumulation, both from external sources (environmental dust) and internal wear (brake pad debris), significantly impacts this interaction. This study explores the effects of dust on the frictional performance, wear characteristics, and thermal properties of brake systems. It highlights the mechanisms by which dust influences brake efficiency, the challenges posed by dust accumulation, and potential solutions to mitigate these effects.

Keywords: braking system, critical safety components, automobiles.
