Energy and emission

Emission from vehicles is one of causes of environmental pollution and threat to human health. Magnetic levitation (Maglev) train with high speed, comfort, low energy consumption and low emission is a good solution to this problem. This paper studies Maglev system as a foundation to develop Maglev trains. The paper also presents a sliding mode control (SMC) combining PID (PID-SMC) control for issues of regulation and tracking of a Maglev system with uncertainty.

The eco-efficiency indicator is recognized as an effective tool to measure sustainability in construction. This study proposes s indicators to measure eco-efficiency at project and component levels during the roadway life cycle. Conventional cost over energy consumption and conventional cost over GHG emissions are two most prominent indicators in the material production stage, whereas conventional cost over solid waste is the most prominent in the disposal/recycling stage.

Enhancing the engine thermal efficiency is an effective way to improve the vehicle fuel economy and vehicle emissions that have drawn extensive efforts toward achieving a sustainable society. However, the lower thermal efficiency of the stoichiometric concept is one of the challenges to meet the fuel economy and emissions regulations of spark ignition (SI) engines.

To the best of our knowledge, a very few studies have focused on the effects of energy consumption on climate change in developing and developed countries. The purpose of this paper is to study the effects of energy consumption on carbon dioxide emission in the South-east Asian countries, including Cambodia, Indonesia, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam.

The surging rate of CO2 emission in the past few years has raised concerns on environmental security for the government and Vietnamese citizens. Rising demands for social development, economic and population growth, enhancing standards of living require the use of energy and possibly increasing carbon dioxide emission, having direct impacts on the environment and human health. Hence, it is necessary to have different analyses assessing the degree of influences on each factor causing CO2 emitted and appropriate approaches to effectively control and reduce the carbon emission.

This paper covers a systematic mapping of the academic sustainability transitions literature, compiling existing evidence on the potential risks and adverse effects of using NG. Methane emissions in particular pose large climate risks, while the main barriers to sustainability transitions caused by NG include a crowding-out effect of low-carbon technologies, stranded assets, infrastructure lock-in, and behavioural lock-ins.

This emissions paradox is explained by differences in building age, rates of home ownership, and floor area in these communities. In African-American neighborhoods, homes are older, home ownership is lower (reducing the likelihood of energy retrofits), and there is less floor area per person compared to Caucasian neighborhoods. Statistical models suggest that historical housing policies, particularly “redlining”, partially explain these differences.

The art industry has commercialised and popularised non-fungible tokens (NFTs), with the volume and value of NFT transactions rapidly growing to US$ 10.7 billion in Q3 2021. The increase in NFT transactions has drawn the attention of the art market to the consequent carbon emissions resulting from verifying transactions in proof-ofwork blockchains supporting NFT transactions.

The study is based on a combination of qualitative and quantitative methods. A multi-level perspective (MLP) is deployed to discuss how exogenous trends and uncertainties interact with processes and strategies in the national energy system, and how this influences the transition potential associated with Norwegian hydrogen production.

Although the western Anatolian region is a foci for hydrothermal systems, this region has several high heat-generating granitic intrusive bodies that qualify to be candidates for enhanced geothermal systems (EGS). Considering the future energy requirement, carbon dioxide emissions reduction strategies, food, and water security issues, these granites appear to be the future clean energy source for the country. One such granite intrusive is located in the Kestanbol area in the western Anatolian region.

The noncondensable gases in most geothermal resources include CO2 and smaller amounts of other gases. Currently, the worldwide geothermal power is a small sector within the energy industry, and CO2 emissions related to the utilisation of geothermal resources are consequently small. In some countries, however, such as Turkey and Iceland, geothermal energy production contributes significantly to their energy budget, and their CO2 emissions are relatively significant.

The as-deposited thin films were characterized by powdered X-ray diffraction and field emission scanning electron microscopy. Thin films of CdS deposited at low temperature (350◦C) consist of densely packed granular crystallites with an average size of ca. 150 nm, while at higher temperatures (400 and 450◦C) particles with varying sizes and mixed morphologies are observed. The ZnS thin films deposited at 400◦C showed rod-like structures, whereas dense globular-like structures were obtained at 450◦C.

This paper presents the evaluation of the Thick Target Particle Induced X-rays Emission (TTPIXE) technique using standard samples. The element-dependent standardization factor, H, as a function of X-ray energies is calibrated using standard sample NIST-611 and validated with two standard samples: IAEA-Soil7 and NIES-Pepperbush. The obtained results are in good agreement with the reference data.
