Electrified Vehicles

The U.S. Department of Energy’s Vehicle Technologies Office (DOE-VTO) supports research and development (R&D), as well as deployment of efficient and sustainable transportation technologies, that will improve energy efficiency and fuel economy and enable America to use less petroleum. To accelerate the creation and adoption of new technologies, DOE-VTO has developed specific targets for a wide range of powertrain technologies (e.g., engine, battery, electric machine, lightweighting, etc.). This paper quantifies the impact of VTO R&D on vehicle energy consumption and cost compared to expected historical improvements across vehicle classes, powertrains, component technologies and timeframes. We have implemented a large scale simulation process to develop and simulate tens of thousands of vehicles on U.S. standard driving cycles using Autonomie, a vehicle simulation tool developed by Argonne National Laboratory. Results demonstrate significant additional reductions in both cost and energy consumption due to the existence of VTO R&D targets compared to predicted historical trends. It is observed that, over time, the fuel consumption of different electrified vehicles is expected to decrease by 40–50% and a reduction of 45–55% for vehicle manufacturing costs owing to significant improvements through various VTO R&D targets.

The U.S. Department of Energy’s Vehicle Technologies Office (VTO) supports research, development, and deployment of efficient, sustainable transportation technologies that will improve energy efficiency and fuel economy, and enable America to use less petroleum. To accelerate the development and adoption of new technologies, VTO has developed specific targets for a wide range of powertrain components, including the energy storage system. In this study, we use Autonomie, Argonne National Laboratory’s (Argonne’s) vehicle system simulation tool to evaluate future energy storage requirements (power, energy, etc.) for different vehicle classes, powertrains, component technologies and timeframes. BatPac, Argonne’s tool dedicated to energy storage pack design and costs, is then used to quantify the materials required for each pack. Market penetrations are then used to estimate the overall material demand worldwide and in the United States, with or without recycling. The results demonstrate that the positive impact of VTO research and development will lead to significant reduction in material compared to business-as-usual due to new anode and cathode designs, along with acceleration in battery cell chemistry penetrations. In terms of material demands, it is observed that lithium demand reaches about 80,000 tons (by a factor of 42–45), nickel demand reaches about 500,000 tons (by a factor of 47–56), manganese demand reaches about 30,000–50,000 tons (by a factor of 20–34), and cobalt demand reaches about 30,000 tons (by a factor of 13–28) in the future by 2050. The individual material demand per unit energy, however, decreases significantly in the future due to advances in VTO research and development activities. The increase in battery material demands is mostly driven by increased electrified vehicle fleet penetration in the markets.

The growth prospects for coal production in Russia are not so clearly evident as it may seem. Today there is a wide range of alternative avenues of advancement for the coal sector, which can be explained by the external and internal challenges critical to the development of the coal industry in Russia. The basic risks potentially capable to cause the most adverse effect on the coal industry performance in the years to come include: the coal market slump in the world; ecological risks; risks due to sanctions imposed by the USA and European Union to restrict import of new technologies and attraction of financial assets; social risks. Aiming to evaluate the impact of these risks on the coal industry performance in the coming years, four look-ahead scenarios are developed: baseline, hazardous (baseline), moderate, and hazardous (moderate). The moderate scenario is found to be more innovative than the baseline scenario. The highest rate of introduction of technological innovations is representative of the technologies with lower level of the predicted output of coal. This study has been partly supported by the Russian Foundation for Basic Research in the framework of R&D Project No. 18-010-00467 Development of Economic Indicators and Production Data for the Coal Industry Development in Russia up to 2035 with the Changing Vector of Global Technological Innovation due to Implementation of Industry 4.0 Program.

People whose professional activity is associated with high energy consumption have a completely different lifestyle, unusual for the average person engaged in mental activity. They are directly related to one thing in common - high levels of physical activity. This leads to a large expenditure of the body's own energy and the breakdown of muscle tissue. To maintain the optimal state of a person during a period of intense activity, it is necessary to replenish energy costs in order to avoid the development of an extreme state, which is characterized by a severe state of the body, which develops under the influence of extreme emergency factors of the external and internal environments and is characterized by significant disorders of the body's vital functions. The article discusses issues related to rations for people with increased physical activity in extreme situations. Despite the fact that on the food market for people with increased physical activity there is a wide range of various snacks that are part of pocket and dry rations, one of the important tasks is to develop a modern food product that provides an increase in nutritional value. The existing rations are of insufficient nutritional value. The solution to this problem is possible through new technologies. The most promising are finely ground mixtures of various vegetables and fruits in combination with grain products. The creation of a new product in the form of a mixture for biscuits will expand the range of functional products and increase the profit of enterprises, since sales of such products in 2019 amounted to 274 billion rubles, which is 16 billion rubles more than in 2018. Biscuits from a multicomponent mixture with a high-grade protein in the composition will allow you to quickly restore the energy consumption of highly active people.

Abstract The impact of information and communications technologies (ICT) on the environment is a complex highly-debated subject. Indeed, ICT can have both positive and negative impacts on the environment. While ICT tools and devices can be used to improve energy efficiency, which results in reduced CO2 emissions and environmental degradation, the manufacturing and use of ICT devices can become a major source of emission. Also, many ICT devices contain non-renewable and non-recyclable components that can cause significant environmental damage. Therefore, one may question that whether ICT improves environmental quality in countries with different income levels? To answer this question, this study investigated the environmental impacts of ICT in three groups of high, middle, and low-income countries from 2005 to 2019 using the Generalized Method of Moments (GMM). The ICT Development Index (IDI) was used as the measure of ICT development. Empirical results showed that the use of ICT led to reduced total CO2 emissions, CO2 emissions from solid fuel consumption, CO2 emissions damage, particulate emissions damage, and energy consumption in the studied countries. Therefore, ICT was found to have a generally negative (favorable) impact on environmental degradation in these countries. Considering this effect of ICT on environmental degradation and pollution, governments are recommended to pursue their energy consumption and emission objectives by promoting the use of ICT in the environmental sector and the implementation of green ICT projects.

The Impact

The body of literature on climate change impacts on building energy consumption is rising, driven by the urgency to implement adaptation measures. Nevertheless, the multitude of prediction methodologies, future scenarios, as well as climate zones investigated, results in a wide range of expected changes. For these reasons, the present review aims to map climate change impacts on building energy consumption from a quantitative perspective and to identify potential relationships between energy variation and a series of variables that could affect them, including heating and cooling degree-days (HDDs and CDDs), reference period, future time slices and IPCC emission scenarios, by means of statistical techniques. In addition, an overview of the main characteristics of the studies related to locations investigated, building types and methodological approaches are given. To sum up, global warming leads to: (i) decrease in heating consumptions; (ii) increase in cooling consumption; (iii) growth in total consumptions, with notable differences between climate zones. No strong correlation between the parameters was found, although a moderate linear correlation was identified between heating variation and HDDs, and total variation and HDDs. The great variability of the collected data demonstrates the importance of increasing specific impact studies, required to identify appropriate adaptation strategies.

It is devoted to the problem of analyzing memes as a tool of information warfare. The article analyzes the history and origin of the study of memes as a phenomenon of information interaction and social technology. Memes can be interpreted as: image, idea, symbol, action, any cultural information copied by one person from another; the collective unconscious at the moment of acquiring verbal and visual form; specially created information message, which is distributed in the information space and is intended to form the necessary picture of the human world and make appropriate decisions. The meme influences the perception of reality and drives action. Different types, types of memes and their characteristics are considered. There is a diversity of spread of this phenomenon: global Internet memes, understandable to a wide range of people, and local memes that require specific awareness (gaming, hacking, scientific, professional). Emphasis is placed on the use of memes in contemporary armed conflicts. The information war, combined with the peculiarities of the modern information society, led to the use of new technologies to influence the mass consciousness, in particular, memetic weapons. The article analyzes memetic weapons as a technology of using memes for the distribution of beneficial information in the information space of the object of information confrontation. Particular attention was paid to the analysis of the perceptions of memes by ATO participants and volunteers. The urgency of the problem is determined by the need to analyze the impact of ideas reflected in Internet memes on the mass consciousness during the Russo-Ukrainian war. Within the framework of the Polish-Ukrainian project "Crisis Intervention – Support for NGOs in Ukraine Working with ATO Soldiers and Their Families", 20 flexible interviews were conducted. The focus of the study may be to analyze the perception and functioning of political Internet memes on social media. Empirical studies of the influence of Internet memes on the structural components of the psyche of Internet users are also promising. The war in eastern Ukraine reaffirmed the paradigm shift of modern warfare, demonstrated the thoroughness of a thorough study of the phenomenon and the need to develop entirely new approaches to the realization of political and military goals.

This abstract starts with the purpose of the study of the impact of using new technologies on cropping pattern particularly in the case of the Eastern hills. It also examines the role of governmental organizations and non-governmental organizations to improve agricultural systems of this area. Relevant data have been obtained from both primary and secondary sources. It draws on the data collected from interview, focus group discussion, key informant survey, and field observation. For this, 30 percent sample households were selected from three altitude belts such as upper, middle and lower, ranging from 300 to 2,250 masl along the Koshi-highway. It has a wide range of climates, ranging from sub-tropical to alpine with monsoon precipitation in the summer for three and half months, and therefore it has diversity in flora and fauna and people. Similarly, secondary data have been collected from various books, journals and official records. This paper has showed that the crucial impact of acceptance of innovative methods in agriculture in the study area is a joint effort of local people, government, and non-government agencies too. The government with the development agencies and non-government organizations has contributed to impart knowledge of the agriculture innovative methods to the local farmers. At the same time, the farmers were enthusiastic to learn and adopt those methods. Consequently, one can easily see the remarkable changes in cropping pattern due to the impact of such innovations. The cereal crops based on agricultural system is gradually moving towards high value off-season crops farming.

[Id]Berkembangnya penggunaan mesin e-voting dan meningkatnya penerapan pemilu dalam jaringan (daring) mengindikasikan bahwa masyarakat percaya akan performansi teknologi informasi dalam meningkatkan proses pemilu. Kesuksesan implementasi teknologi informasi mutlak dibutuhkan, Sebagai dukungan kesuksesan tersebut diperlukan analisis yang mendalam. Sebelum mengimplementasikan teknologi e-voting, pemerintah perlu mengetahui tingkat kesediaan (willingness) masyarakat untuk menggunakan teknologi baru. Tingkatan tertentu bahwa ekspektasi seseorang dapat terpenuhi dengan baik adalah definisi dari kepercayaan (trust). Kepercayaan masyarakat teridentifikasi sebagai faktor utama untuk mempengaruhi niat/ kemauan masyarakat menggunakan sebuah teknologi. Penelitian ini menganalisis pengaruh dari faktor kepercayaan terhadap niat untuk menggunakan e-voting. Penelitian ini mengusulkan sebuah model yang menggambarkan niat masyarakat untuk menggunakan e-voting (Intention to use) dengan mengidentifikasi kepercayaan masyarakat terhadap teknologi (trust of technology). Trust dibagi menjadi beberapa faktor yang lebih spesifik. Kuisioner kertas disebarkan kepada 370 masyarakat negara Indonesia dan 346 di antaranya valid. Kuisioner disebarkan secara langsung oleh surveyor kepada masyarakat yang telah memiliki hak pilih dan disebar secara merata kepada golongan umur yang bervariasi, serta tingkat Pendidikan maupun profesi yang beragam. Hasil penelitian menunjukkan bahwa semakin tinggi Trust of Technology (TOT) dapat meningkatkan niat masyarakat untuk menggunakan e-voting (Intention to Use E-voting - ITU). Ditemukan juga beberapa faktor dapat mempengaruhi pengaruh positif terhadap kepercayaan masyarakat terhadap teknologi. Hasil dari penelitian ini menunjukkan bahwa pemerintah diharapkan untuk memperhatikan fakto-faktor yang mempengaruhi kepercayaan masyarakat yang berujung niat dan kemauan masyarakat untuk menggunakan e-voting sebelum menerapkan e-voting tersebut.Kata Kunci: Kepercayaan, Keinginan, Keamanan, Validitas, Pemilu.[En]Increasing adoption of the electronic voting machine and rising pilot testing of internet voting suggests people believe that ICT can improve the electoral process. Since every new technology adoption needs to achieve successful implementation, deeper analysis on several sides was needed to support it. Before implementing a particular e-voting technology, the government needs to know the level of citizen willingness to adopt those new technologies. The expectancy that promise of an individual or group can be relied upon is defined as trust. The citizen trust can be identified by certain factors that lead to intention to use actual system. This study analyzes the impact of trustworthiness on citizen intention to use e-voting system in a developing country. The research proposes a model of e-voting adoption intention by investigating citizen trustworthiness from trust of technology (TOT). The trust was expanded to more specific unique factors. Offline questionnaires were spreaded to 370 respondents and 346 of them were valid. Questionnaires were distributed directly by surveyors to people who have the right to vote and distributed equally for a wide range of ages, as well as varying levels of education and professions. The results indicate that higher TOT increase citizen intention to use e-voting, and also several key determinants have positive influence on the citizen trust. This result suggested that government should first comply with several factors in citizen trustworthiness before conducting an e-voting system.

Research to develop new technologies for increasing the safety of passengers and crew in rail equipment is being directed by the Federal Railroad Administration’s (FRA’s) Office of Research, Development, and Technology. Crash energy management (CEM) components which can be integrated into the end structure of a locomotive have been developed: a push-back coupler and a deformable anti-climber. These components are designed to inhibit override in the event of a collision. The results of vehicle-to-vehicle override, where the strong underframe of one vehicle, typically a locomotive, impacts the weaker superstructure of the other vehicle, can be devastating. These components are designed to improve crashworthiness for equipped locomotives in a wide range of potential collisions, including collisions with conventional locomotives, conventional cab cars, and freight equipment. Concerns have been raised in discussions with industry that push-back couplers may trigger prematurely, and may require replacement due to unintentional activation as a result of service loads. Push-back couplers (PBCs) are designed with trigger loads meant to exceed the expected maximum service loads experienced by conventional couplers. Analytical models are typically used to determine these required trigger loads. Two sets of coupling tests have been conducted to demonstrate this, one with a conventional locomotive equipped with conventional draft gear and coupler, and another with a conventional locomotive retrofit with a push-back coupler. These tests will allow a performance comparison of a conventional locomotive with a CEM-equipped locomotive during coupling. In addition to the two sets of coupling tests, car-to-car compatibility tests of CEM-equipped locomotives, as well as a train-to-train test are also planned. This arrangement of tests allows for evaluation of the CEM-equipped locomotive performance, as well as comparison of measured with simulated locomotive performance in the car-to-car and train-to-train tests. The coupling tests of a conventional locomotive have been conducted, the results of which compared favorably with pre-test predictions. This paper describes the results of the CEM-equipped locomotive coupling tests. In this set of tests, a moving CEM locomotive was coupled to a standing cab car. The primary objective was to demonstrate the robustness of the PBC design and determine the impact speed at which PBC triggering occurs. The coupling speed was increased for each subsequent test until the PBC triggered. The coupling speeds targeted for the test were 2 mph, 4 mph, 6 mph, 7 mph, 8 mph, and 9 mph. The coupling speed at which the PBC triggered was 9 mph. The damage observed resulting from the coupling tests is described. Prior to the tests, a lumped-mass model was developed for predicting the longitudinal forces acting on the equipment and couplers. The test results are compared to the model predictions. Next steps in the research program, including future full-scale dynamic tests, are discussed.
