The researchers from the University of Cambridge have developed an algorithm, which gives an accurate measurement of tree diameter, an important measurement used by scientists to monitor forest health and levels of carbon sequestration. The algorithm uses low-cost, low-resolution LiDAR sensors that are incorporated into many mobile phones, and provides results that are just as accurate, but much faster, than manual measurement techniques
Previous material solution for industrial inverter applications was PC/ABS for more than 10 years. Recently, PC/ABS has been reduced in the market due to customer needs for improved performance of existing materials and market trends for improved material like raising carbon credits are emphasizing the need for eco-friendly environmental technologies and rapidly growing smart factories to deliver, smart power consumption technologies for environmental protection and energy saving. This trend is rapidly changing in common life and various industries, so new material solutions are required to improve effective material solutions such as less or no outgassing, thermal stability and lower process temperature availability, color stability, better flame retardant properties and so on. In this study, according to new industry requirements, material evaluation was conducted with SABIC NORYLTM N-series PPE resins and incumbent PC/ABS material. Through various experiments, we confirmed the
As we move towards greener technologies in the transportation sector, it becomes mandatory to monitor its impact or the utilization of such a technology in the intended manner. Improper usage results in lesser utilization of benefits of such green technologies. One such scenario is the range anxiety; users of parallel hybrid vehicles face a dilemma between charging and refueling the vehicle. If the hybrid vehicle is operated in a gas-powered mode most of the time, the emission levels would be comparable to those of gas-powered vehicles. On the other hand, gas-powered vehicles have no mechanism to completely cut CO2 emissions, unlike hybrids (electric drive). Emission regulatory bodies are facing difficulties in regulating each road vehicle. Therefore, the actual emission levels emitted from the vehicles are higher than the estimate provided by regulations. This paper discusses the possibility of implementing a Carbon Credit Scoring for each class of vehicles. The paper also proposes
Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the carbon dioxide (CO2) can be released in a controlled way and collected to be reused or disposed of responsibly
As it became clear at the onset of COVID-19 pandemic that the novel coronavirus was transmitted through the air, several companies realized their NASA-derived air-quality technologies could help combat its spread. And they soon found themselves overwhelmed by demand from schools to hospitals, shopping centers, office buildings, airports, and even buses
Recent technical advances have enabled flywheel energy storage systems (FESS) to become more compact and able to support higher-power applications. Due to their proven reliability, low cost of ownership, and favorable green environmental aspects, engineers and managers of data centers, hospitals, industrial systems, electric rail, and microgrid applications are reaping the benefits of clean energy storage that flywheels offer
Recent automotive trend shows that customer demand is moving towards bigger size vehicle with more comfort, space, safety, feature and technology. Global market of SUV is projected to surpass 21 million units by 2020. Despite economic slowdown and weak new car sales worldwide, India and China will continue to be primary market for SUV due to sheer size of population, urban expanding middle class and larger untapped rural market. However, stricter emission norms push for clean and green technology and unfavorable policy towards use of diesel vehicle has made the SUV design very challenging due to conflicting needs. Due to bigger size of vehicle, aerodynamic design plays an important role in achieving emission targets and higher fuel efficiency. This paper highlights the aerodynamic development of Maruti Suzuki Vitara Brezza, which is an entry level SUV vehicle with high ground clearance of 198 mm and best in class fuel economy of 24.3 kmpl. CFD has been extensively used for exploring
Aerodynamics plays a key role in nowadays vehicle development, aiming efficiency on fuel consumption, which leads to a green technology. Several initiatives around the world are regulating emissions and efficiency of vehicles such as EURO for European Marketing and the INOVAR Auto Project to be implemented in Brazil on 2017. In order to meet requirements in terms of performance, especially on aerodynamics, automakers are focusing on aero-efficient exterior designs and also adding deflectors, covers, active spoilers and several other features to meet the drag coefficient. Usually, the aerodynamics properties of a vehicle are measured in both CFD simulations and wind tunnels, which provide controlled conditions for the test that could be easily reproduced. During the real operations conditions, external factors can affect the flow over the vehicle such as cross wind in open highways. The aerodynamic behavior of the vehicle can also be affected by the influence of the user such as by
Nowadays, one of the most important roles in vehicle development is the aerodynamic, which aims efficiency on fuel consumption and leads to a green technology. Several initiatives around the world are regulating emissions and efficiency of vehicles such as EURO for European Marketing and the INOVAR Project to be implemented in Brazil on 2017. Thus, this study intend to perform an optimization to minimize the drag force of a hatchback vehicle. The main goal of this work is demonstrate the potential of optimization techniques to provide an aerodynamic shape improvement for the driver side outside rear view mirror of a hatchback vehicle. The optimization solver used in this work is the Adjoint Solver, which makes shape sensitivity analysis and mesh/volume morphing. The study was conducted using CFD simulations to reduce the drag force of current production hatchback vehicle previously validated and correlated in wind tunnel test. Firstly, the optimization solver is used to improve the
Electric Motor and Drivetrain (Electric Mobility) Testing is a critical part of bringing any electric drivetrain into production. In this paper the requirements for an electric drivetrain test cell are discussed. The implementations of such test cells are described and examples of test results are provided. In particular, the energy and power requirements for PM brushless DC dynamometers and a PM brushless Unit Under Test (UUT) connected through a common dc bus are described. Simulation of the set-up is developed using MATLAB/Simulink and verified using empirical data from the test bench. The data used represents various steady state load conditions during durability test cycles. This “Smart Green Technology” concept not only reduces the energy requirement from the grid but also eliminates the inefficiencies related to putting energy back on the grid
Due to the air pollution and energy crisis, the added values to environmental protection from the green technology passenger cars have received scrutiny by consumers. In order to enhance the comprehension of consumers' acceptance in green technology passenger cars, the goal of this study is to promote automotive designer's understanding on the affective response of consumers on automotive form design. In general, consumers' preference is mainly based on the vehicles' form features that are traditionally manipulated by designers' intuitive experience rather than an effective and systematic analysis. Therefore, when encountered the increasing competition in automotive market nowadays, enhancing the car designer's understanding of consumers' preference on the form features of green technology passenger cars to fulfill customers' demands has become a common objective among automotive makers. In this paper, adjective evaluation data of customers were screened first from questionnaire to
The environmental issues confronting the automotive industry are legion at a time when the industry has not been in the best position to respond. Concerns have been raised that the industry needs to be producing “green mobility products” without definition, specificity, or expression of customer need. Business infrastructure and the regulatory landscapes are uncertain, but likely to be restrictive for the automotive sector, especially with regard to the environment and green issues. Actions the automotive industry could consider include: develop a common dictionary of terms related to “green mobility products”; address the issues affecting the industry before regulations are imposed; make the Mobility Sector part of the solution; focus on being environmentally responsive, cost-saving, and time-sensitive; and assure that the Mobility Sector is recognized as a leader for new, green technology. Following an SAE workshop that addressed these issues and was supported by the State of
The deal transferring Volvo's ownership to the Zhejiang Geely Holding Group is expected to be sealed before the fourth quarter of this year, offering a lower cost base that could see Volvo sales up from about 390,000 this year to a million by 2016. There was a time not so long ago when the mere possibility of Volvo (which managed to retain its quintessentially Swedish identity under Ford) becoming part of a Chinese industrial organization would have seemed as unlikely as General Motors filing for Chapter 11 protection. But as the auto industry entered the 21st century, it emerged that the only certainty was uncertainty, and the deal transferring Volvo's ownership to the Zhejiang Geely Holding Group is expected to be sealed before the fourth quarter of this year, offering a lower cost base that could see Volvo sales up from about 390,000 this year to a million by 2016
The increasing emphasis on green technologies has focused more attention on low power design. Microcontroller vendors are responding by increasing their offerings of ultra low power devices that consume as little as 350 uA/MHz and have sub-uA sleep modes
