SatNOGS: Satellite Networked Open Ground Station

Abstract—The SatNOGS, or Satellite Network Open Ground Stations, project promotes and supports free and open space applications. It seeks to solve the problem of connecting many satellite users/observers to many ground station operators. Modern open software, web, and hardware techniques are used in implementing the Network, Database, Client, and Ground Station sub- projects. Modularity in all the systems promotes the dual-use of ground stations by not interfering with local operation while utilizing the great amount of time a civilian, non-commercial ground station would otherwise sit idle

Is Demonstrating the Concept of Multi-Use Too Soon for the North Sea?:Barriers and Opportunities from a Stakeholder Perspective

Multi-use (MU) has been promoted as a viable approach to the effective planning and mitigation of user-conflicts in the marine realm. Despite several research and pilot projects demonstrating the approach’s feasibility and benefits, commercially viable MU applications remain patchy and few. Further, MU is neither systematically applied nor purposively planned for even in the imminent event of incompatible and conflicting use of marine space. This paper seeks to identify barriers and opportunities for mainstreaming MU based on desktop study and iterative stakeholder consultation. The findings reveal that the MU concept was frequently framed as ‘co-location’ or ‘co-existence’ and aimed toward mitigating conflict among users. Practice was ahead of theory with little attention to synergistic and efficiency aspects. Barriers for MU application include shortcomings in legislation, sectoral thinking, and burdensome administrative procedures. The main opportunity lies in creating a conducive policy environment where MU risks and transaction costs become low and competitive, respectively. Solutions at the sea basin and national level, upon which further MU application can be anchored, are proposed

Impact assessment of its applications for vulnerable road users

The EU-sponsored VRUITS project has prioritized ITS applications which have a potential to improve the safety, mobility and comfort of vulnerable road users (VRUs) and performed a quantitative safety, mobility and comfort assessment for the 10 most promising systems. The assessment methodology addresses not only the direct effects of the systems, but also unintended effects and effects through changes in mobility patterns. The 10 selected ITS were: VRU beacon system, Powered Two Wheelers oncoming Vehicle information, Bicycle-to-vehicle communication, Cooperative Intersection safety, Green wave for cyclists, Pedestrian & Cyclist detection with Emergency Braking, Blind spot detection, Intelligent pedestrian traffic signal, Crossing adaptive lighting and Information on bike rack vacancy. The paper presents the quantitative estimates for the impact on safety, mobility and comfort. The outputs of the impact assessment are translated into socioeconomic indicators via a social cost-benefit analysis

AMITRAN methodology for CBA and CEA of ITS measures

The Amitran project provides a methodology for evaluating the effects of ICT measures in traffic and transport on energy efficiency and CO2 emissions. Last step of the methodology is the possibility to carry out a CBA or CEA of the ITS measures which are investigated. This paper presents the Amitran quick-scan CBA: the results will give the user an overview of the relevant effects in monetary terms that will give him or her a first indication to determine whether or not the ITS implementation is profitable for society

Growth Development, Physiological Status and Water Footprint Assessment of Nursery Young Olive Trees (<em>Olea europaea</em> L. ‘Konservolea’) Irrigated with Urban Treated Wastewater

Application of urban treated wastewater (TWW) has been practiced globally as an alternative irrigation water source in areas where access to safe and abundant freshwater is limited. Water footprint (WF) has been employed over the last decades as a tool for the assessment of the sustainable management of water resources. In the present study, the suitability of TWW for the irrigation of nursery young olive trees (Olea europaea L. ‘Konservolea’), one of the main table olive cultivars in Greece, the second global table olive exporter, was tested and compared to tap water irrigation and application of zeolite on soil. Plant growth and physiological parameters and stress indicators were measured. Additionally, a WF assessment was performed, distinguishing TWW from freshwater (blue water) resources in order to examine the possibility of minimizing the environmental impact through the limitation of freshwater use. Plants irrigated with TWW performed better in most of the growth and physiological parameters measured compared to the other treatments. Stress indicators revealed that TWW did not induce any additional stress. TWW could be used as an irrigation water source for young olive trees for at least a short period during their growth as a safe and sustainable alternate of blue water resources. Additionally, the WF assessment showed that the application of TWW could be a significant blue water saving measure

Validation and uncertainty estimation for conformity declaration of a method to assess the stability of nitrocellulose-based propellants

The scope of the present study was to develop and validate a rapid and precise method for the evaluation the stability and the chemical life of nitrocellulose-based propellants which contain as stabilizers diphenylamine, N-nitrosodiphenylamine, 2-nitrodiphenylamine, 4-nitrodiphenylamine and ethyl centralite. This was made by using the calculation of the weight percentage concentration (% w/w) of the initial effective stabilizer, the calculation of the weight percentage concentration (% w/w) of the effective stabilizer after artificial ageing, as well as the reduction of the concentration as a % percentage. All crucial parameters were investigated and optimized. The validation and the uncertainty estimation of the method was based on the Eurachem Guidelines. The recovery of the method was found higher than 95% and the RSD values were found less than 10%. The ageing procedure was found to be the most important factor influencing the uncertainty. The present study describes a very important procedure for ammunition management and the way to provide a declaration of conformity for safe use and storage

Recommendations for actions concerning supporting ITS developments for VRUs

Abstract Introduction This paper presents some of the work conducted in FP7 VRUITS project to draw a set of general recommendations for actions at the EU level aiming to enhance the deployment of ITS systems directed to improve the safety, mobility and comfort of vulnerable road users. Method The work started by identifying potential barriers, as well as recommendations to overcome these barriers. After that, similar recommendations were combined and prioritised, which are discussed via a workshop and questionnaire. In addition, a qualitative analysis was used to select thirteen main recommendations, for which a quantitative Benefit Analyses and a Multi-Criteria analysis were conducted. Results In total, over 200 barriers and recommendations were identified for the 10 selected ITS systems. After several steps 13 main general recommendations were selected and ranked according to priority. Conclusions 1) A wide range of different type of measures directed to different stakeholders is needed 2) Focus should be on facilitating the implementation of the 13 main recommendations, 3) Benefits of implementation of the recommendations can be in the order of billion(s) of euros, and 4) Main challenges are achieving cooperation between the different stakeholders, the different environments, the long time horizon for implementation and the high implementation costs
