CERN Multimedia. Students from Norway, Italy and Geneva college Voltaire cam to CERN to follow seminars on cosmic rays and to assemble a special cosmic ray detector prototype, PolarquuEEEst, to be installed on board Arctic sailing vessel Nanuq to detect cosmic rays close to the North Pole this summer. The project is part of the EEE initiatives launched by prof. Zichichi and organized by Centro Fermi. The EEE Project status and perspectives.
The Extreme Energy Events EEE project plans to build and use an array of cosmic ray telescopes for muon detection, distributed over the italian territory. The use of such telescopes, based on Multigap Resistive Plate Chambers MRPC will allow the study of cosmic ray showers and the correlation between multiple primaries producing distant showers. The project is also intended to involve high school teams in an advanced research work.
The physics items which can be addressed by such array, and the present status and perspectives of the project are here discussed.
Storage of EEE part represents a key process in space electronics activity. In order to cope with projects time schedule on one hand and with economical procurement constraints on the other hand, parts are often to be stored for quite a long time. Obsolescence issues could make us to build strategic stock in order to be able to still manufacture equipments over time.
Up to now several documents ruled the way to de-store relifed EEE part in such a way we are able to guaranty their reliability despite their long period of storage. None of these documents backed up their figures and rules with consistent approach and physics. No field return existed or was used to assess these rules. In the frame of a contract from CNES we established an updated rule taking into account field-return and failure mechanisms analysis.
We ended up by a new storage and de-storage procedure that is to be included in the ECSS format. The computing and data infrastructure to interconnect EEE stations. The Extreme Energy Event EEE experiment is devoted to the search of high energy cosmic rays through a network of telescopes installed in about 50 high schools distributed throughout the Italian territory.
This project requires a peculiar data management infrastructure to collect data registered in stations very far from each other and to allow a coordinated analysis. In EEE started to use it for collecting, monitoring and reconstructing the data acquired in all the EEE stations. All data folders are syncronized with the central repository in real time to allow an immediate reconstruction of the data and their publication in a monitoring webpage. We present the architecture and the functionalities of this data management system that provides a flexible environment for the specific needs of the EEE project.
Noferini, F. EEE environmental engineering economics attributes for oil and gas industry. This paper outlined the basic attributes of environmental engineering economics EEE with reference to the oil and gas industry in Australia.
The paper was designed as a reference guide for policy-makers, educators, and environmental engineers. Methods of calculating the Pareto Optimum status were discussed, and environmental values and principles were identified. Air quality indicators were outlined. The paper considered multidisciplinary approaches to EEE and sustainable development, as well as the application of statistics and qualitative methods in addressing contemporary issues.
The ethical aspects of environmental policies were discussed. Issues related to environmental toxicity and public health were also examined.
Various taxation approaches and financial incentives were reviewed. Environmental laws related to the oil and gas industry were outlined. Environmental assessment procedures were presented. It was concluded that environmental regulations within the industry will help to ensure appropriate pollution reductions.
In the cold flow calculation, the AUSM scheme predicts a much stronger reverse flow in the central recirculation zone. In the reacting flow calculation, we test two cases: gaseous fuel injection and liquid spray injection.
In the gaseous fuel injection case, the overall flame structures of the two schemes are similar to one another, in the sense that the flame is attached to the main nozzle, but is detached from the pilot nozzle. However, in the exit temperature profile, the AUSM scheme shows a more uniform profile than that of the JST scheme, which is close to the experimental data.
In the liquid spray injection case, we expect different flame structures in this scenario. We will give a brief discussion on how two numerical schemes predict the flame structures inside the EEE using different ways to introduce the fuel injection. This presentation includes an FY18 program overview. S; Zichichi, A; Zouyevski, R. Data from two different telescopes of the EEE network have been analyzed and compared to those measured by neutron monitor stations. The variation of the muon counting rate during the Forbush decrease was also extracted for different intervals of the azimuthal angle of the incoming muons.
The EEE Project: a sparse array of telescopes for the measurement of cosmic ray muons. Rocca, P. La; Abbrescia, M. Baldini; Batignani, G. De; Pasquale, S.
De; Bencivenni, G. Di; D'Incecco, M. To this aim, more than 50 telescopes have been built at CERN and installed in high schools distributed all over the Italian territory. Each EEE telescope comprises three large area Multigap Resistive Plate Chambers MRPCs and is capable of reconstructing the trajectories of the charged particles traversing it with a good angular resolution.
The excellent performance of the EEE telescopes allows a large variety of studies, from measuring the local muon flux in a single telescope, to detecting extensive air showers producing time correlations in the same metropolitan area, to searching for large-scale correlations between showers detected in telescopes tens, hundreds or thousands of kilometers apart.
In addition to its scientific goal, the EEE Project also has an educational and outreach objective, its aim being to motivate young people by involving them directly in a real experiment. High school students and teachers are involved in the construction, testing and start-up of the EEE telescope in their school, then in its maintenance and data-acquisition, and later in the analysis of the data.
During the last couple of years a great boost has been given to the EEE Project through the organization of simultaneous and centralized data taking with the whole telescope array. The raw data from all telescopes are transferred to CNAF Bologna , where they are reconstructed and stored. The data are currently being analyzed, looking at various topics: variation of the rate of cosmic muons with time, upward going muons, muon lifetime, search for anisotropies in the muon angular distribution and for time coincidences between stations.
In this paper an overall description of the experiment is given, including the design, construction and performance of the telescopes. The operation of the whole array is also presented by showing the most recent. With growing acceptance of service-oriented computing, an emerging area of research is the investigation of technologies that will enable the discovery and composition of web services. Tool 1 comes in form of a handbook. The purpose of this handbook is to ease the work with developing more environmentally sound The handbook describes 5 productfamilies: mobile phones, vacuum cleaners, industrial valves with electronic controls, lighting, ventilation.
Tool 2 comes in form of a software tool The tool provides the basic understanding of how EEE -products in general interact with the environment. The tool gives an overview of the tasks and responsibilities involved in Eco-Desing, and examples of how to choose and quantify Blondel, A. This sensitivity is made possible by exploiting modern silicon pixel detectors providing high spatial resolution and hodoscopes using scintillating fibres and tiles providing precise timing information at high particle rates.
Time correlation measurements from extensive air showers detected by the EEE telescopes. Time correlated events due to cosmic muons from extensive air showers have been detected by means of telescope pairs of the EEE Extreme Energy Events Project array. The coincidence rate, properly normalized for detector acceptance, efficiency and altitude location, has been extracted as a function of the relative distance between the telescopes.
The results have been also compared with additional measurements carried out by small scintillator detectors at various distances. The Extreme Energy Events EEE project started to use an array of cosmic ray telescopes for muon detection, distributed over the italian territory. The use of such telescopes, based on Multigap Resistive Plate Chambers MRPC allows the study of the local muon flux, the detection of cosmic ray showers and the search for correlations between distant showers.
The present status of the installation and the first physics results are discussed here. Abbrescia, M. Fermi, Roma Italy ; Blanco, F. Fermi, Roma Italy ; Cicalo, C. The EEE Extreme Energy Events Project, conceived by its leader Antonino Zichichi, is an experiment to study very high-energetic air showers EAS through the detection of the shower's muon component using a network of tracking detectors, installed in Italian high schools.
The data collected by the telescopes will be used for studies of air showers and also for the search of time correlations between sites which are far apart. The first telescope, recently installed in the Liceo B. Touschek in Grottaferrata Rome , is successfully running, and other telescopes are going to be installed in a short time in other towns, opening up the way for the first search of long-distance coincidences over a total area of. Operation and performance of the EEE network array for the detection of cosmic rays.
The main scientific goals of the Project are the investigation of the properties of the local muon flux, the detection of Extensive Air Showers EAS and the search for long-distance correlations between far telescopes. The Project is also characterized by a strong educational and outreach aspect since the telescopes are managed by teams of students and teachers who had previously constructed them at CERN.
The operation of the whole array, which currently consists of more than 50 telescopes, is also presented by showing the most recent physics results. This Standard reflects current practices, instead of changing them. A gap analysis clearly shows the differences that exist among the different centers and with respect to the NASA Parts Policy.
Once approved, the new standard can be referenced in contracts and agreements with organizations outside of NASA. Coneixem als nostres estudiants? Directory of Open Access Journals Sweden. The objective of this paper is an assessment of high voltage electronic components required for high horsepower electric thrust vector control TVC systems for human spaceflight launch critical application.
The scope consists of creating of a database of available Grade 1 electrical, electronic and electromechanical EEE parts suited to this application, a qualification path for potential non-Grade 1 EEE parts that could be used in these designs, and pathfinder testing to validate aspects of the proposed qualification plan. Advances in the state of the art in high power electric power systems enable high horsepower electric actuators, such as the electromechnical actuator EMA and the electro-hydrostatic actuator EHA , to be used in launch vehicle TVC systems, dramaticly reducing weight, complexity and operating costs.
Furthermore, the perception of risk, the lack of qualification methodoloy, the absence of manned space flight heritage and other barriers impede the adoption of commercial grade parts onto the critical path.
