Levels of abstraction in human supervisory control teams

This paper aims to report a study into the levels of abstraction hierarchy (LOAH) in two energy distribution teams. The original proposition for the LOAH was that it depicted five levels of system representation, working from functional purpose through to physical form to determine causes of a malfunction, or from physical form to functional purpose to determine the purpose of system function. The LOAH has been widely used throughout human supervisory control research to explain individual behaviour. The research seeks to focus on the application the LOAH to human supervisory control teams in semi-automated “intelligent” systems

Spacelab J: Microgravity and life sciences

Spacelab J is a joint venture between NASA and the National Space Development Agency of Japan (NASDA). Using a Spacelab pressurized long module, 43 experiments will be performed in the areas of microgravity and life sciences. These experiments benefit from the microgravity environment available on an orbiting Shuttle. Removed from the effects of gravity, scientists will seek to observe processes and phenomena impossible to study on Earth, to develop new and more uniform mixtures, to study the effects of microgravity and the space environment on living organisms, and to explore the suitability of microgravity for certain types of research. Mission planning and an overview of the experiments to be performed are presented. Orbital research appears to hold many advantages for microgravity science investigations, which on this mission include electronic materials, metals and alloys, glasses and ceramics, fluid dynamics and transport phenomena, and biotechnology. Gravity-induced effects are eliminated in microgravity. This allows the investigations on Spacelab J to help scientists develop a better understanding of how these gravity-induced phenomena affect both processing and products on Earth and to observe subtle phenomena that are masked in gravity. The data and samples from these investigations will not only allow scientists to better understand the materials but also will lead to improvements in the methods used in future experiments. Life sciences research will collect data on human adaptation to the microgravity environment, investigate ways of assisting astronauts to readapt to normal gravity, explore the effects of microgravity and radiation on living organisms, and gather data on the fertilization and development of organisms in the absence of gravity. This research will improve crew comfort and safety on future missions while helping scientists to further understand the human body

Regulatory oversight of nuclear safety in Finland : Annual report 2019

Introduction This report is a report on regulatory oversight in the field of nuclear energy provided by the Radiation and Nuclear Safety Authority (STUK) to the Ministry of Economic Affairs and Employment once a year as required by Section 121 of the Nuclear Energy Decree. The report will also be provided to the Ministry of Social Affairs and Health, the Ministry of the Environment, the Finnish Environment Institute and to the environmental authorities of the nuclear facility municipalities. The report is a summary of regulatory oversight of safety in the use of nuclear energy performed by STUK and of the related results in 2019. The regulatory oversight concerned the design, construction and operation of nuclear facilities, decommissioning planning, nuclear waste management and nuclear safeguards. In addition to actual regulatory oversight of safety, the report describes, among other things, the development and implementation of the regulations concerning the use of nuclear energy during the year and the main characteristics of the safety research programmes pertaining to nuclear safety and nuclear waste management in Finland. The annexes to the report contain significant events at the nuclear power plants and inspection summaries of STUK’s inspection programmes. In addition, a summary of the licences accordant with the Nuclear Energy Act granted by STUK in 2019, as required by the Nuclear Energy Decree, is appended to the report. STUK’s Financial Statements and Annual Report 2019 includes an assessment of meeting the performance targets under the performance agreement between the Ministry of Social Affairs and Health and STUK also in view of regulatory oversight in the use of nuclear energy

First International Microgravity Laboratory

This colorful booklet presents capsule information on every aspect of the International Microgravity Laboratory (IML). As part of Spacelab, IML is divided into Life Science Experiments and Materials Science Experiments. Because the life and materials sciences use different Spacelab resources, they are logically paired on the IML missions. Life science investigations generally require significant crew involvement, and crew members often participate as test subjects or operators. Materials missions capitalize on these complementary experiments. International cooperation consists in participation by the European Space Agency, Canada, France, Germany, and Japan who are all partners in developing hardware and experiments of IML missions. IML experiments are crucial to future space ventures, like the development of Space Station Freedom, the establishment of lunar colonies, and the exploration of other planets. Principal investigators are identified for each experiment

China in the Transition to a Low-Carbon Economy

China, from its own perspective cannot afford to, and from an international perspective, is not allowed to continue on the conventional path of encouraging economic growth at the expense of the environment. The country needs to transform its economy to effectively address concern about a range of environmental problems from burning fossil fuels and steeply rising oil import and international pressure to exhibit greater ambition in fighting global climate change. This paper first discusses China’s own efforts towards energy saving and pollutants cutting, the widespread use of renewable energy and participation in clean development mechanism, and puts carbon reductions of China’s unilateral actions into perspective. Given that transition to a low carbon economy cannot take place overnight, the paper then discusses China’s policies on promoting the use of low-carbon energy technologies and nuclear power and efforts to secure stable oil and gas supplies during this transition period. Based on these discussions, the paper provides some recommendations on issues related to energy conservation and pollution control, wind power, nuclear power, clean coal technologies, and overseas oil and gas supplies, and articulates a roadmap for China regarding its climate commitments to 2050.Energy Saving, Renewable Energy, Clean Development Mechanism, Nuclear Power, Power Generation, Oil and Gas, Post-Copenhagen Climate Negotiations, China

Calculating CARMA: Global Estimation of CO2 Emissions from the Power Sector

This paper provides a detailed description and assessment of CARMA (Carbon Monitoring for Action), a database that reports CO2 emissions from the power sector. We built CARMA to assist the millions of concerned global citizens who can act to reduce carbon emissions once they have timely, accurate information about emissions sources. CARMA also lays the groundwork for the global monitoring system that will be necessary to ensure the credibility of any post-Kyoto carbon emissions limitation agreement. CARMA focuses on the power sector because it is the largest carbon dioxide emitter (26% of the global total), and because power plants are much better-documented than many sources of carbon emissions. The CARMA database and website put anyone with web access a few keystrokes away from detailed knowledge about power plants and the companies that own and operate them. CARMA includes many aggregation tools, so it can be used for local, regional, national and international comparisons. The database also offers complete information about power plants and companies that do not emit carbon because they use non-fossil energy sources (nuclear, hydro, solar, wind, biofuels, geothermal, etc.). In this paper, we provide a description of CARMA’s methodology, an assessment of its strengths and weaknesses, and some tests of its accuracy across countries and at different geographical scales. While CARMA performs well in these tests, we recognize that it is far from perfect. We therefore extend the following invitation to any power plant or company that disputes our estimates: Provide us with better data, verified by an appropriate third party, and we will incorporate them in CARMA.global warming, climate change, emissions, energy
