However there is a significant lack of understanding of what MaaS actually is on conceptual level. Reviewing the state-of-the-art of MaaS research we deduct that MaaS has all the attributes of a `hyped' socio-technical phenomenon: it seems to be a loosely connected patchwork of optimistic political dogma, activists' enthusiasm, anecdotal evidence of successful services and a firm belief of investors in companies such as Uber. However, as a paradigm shift, MaaS has electrified public decision makers and unleashed a wave of innovation in SMEs. In addition, MaaS forces researchers to work in multi-disciplinary collaborations, transcending `traditional' competence areas, such as traffic planning, computer science, social sciences, transport systems and organisational psychology. Consequently, while embracing the innovative spirit of the MaaS paradigm shift, we aim to outline key conceptual issues of MaaS. These issues are 1) the nature of travel (including purpose, mode, means, distance etc.); 2) MaaS interoperability within intelligent traffic services; 3) the end-user perspective, with a focus on user attitudes and behaviours; and 4) sustainability, including work during the journey, and ultimately not traveling at all (e.g. teleworking). We exemplify our tentative concept through applying it to the existing mobility services Uber, Lyft, Car2Go, DriveNow, Tuup, UbiGo and Moovel. Through our study, we provide an initial research based conceptual foundation for MaaS researchers, developers and implementers.","PeriodicalId":412230,"journal":{"name":"2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115775913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is claimed that the new concept can significantly outperforms traditional wind turbines in terms of reducing the diameter of wind turbine, improve aerodynamic characteristics under the same wind conditions, and delivers significantly higher output at reduced cost. The innovative feature of the wind turbine is the elimination of tower-mounted turbines. It is believed that the entry of such systems is crucially important because external flows over nozzle or diffuse devices are different from classically known internal flows. Shrouded wind turbines and wind catcher systems are normally use a diffuser shape at entry, however, the INVELOX concept suggest using a nozzle at entry. In this paper, two different simpler systems than INVELOX are designed with nozzle or diffuser at the entry using general methods in design of blower wind tunnels. In the first phase of this work, CFD (computational fluid dynamics) method is applied to solve external flows around nozzle and diffuser flows by solving the modelled RANS (Reynolds average Navier-Stokes) equations. The initial results indicate that the wind speed retarded at the entry of nozzle while wind speed accelerated at entry of a diffuser device.","PeriodicalId":412230,"journal":{"name":"2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129326349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydraulic drives are often characterized by low efficiencies, heavy maintenance, frequent oil leaks and large weight and size. To overcome these draw-backs, in this paper a concept design of a full-scale permanent magnet linear synchronous motor directly coupled to the shipboard fin stabilizer, is presented, used as a servo-motor. The innovative electric drive is based on prototype of high thrust linear motor built in a previous research. A complete Simulink model, where electric, mechanical and hydraulic domains can be connected, has been realized. Simulations has been performed to evaluate the hydraulic drive efficiency and in order to assess the servo-assistance capabilities. The results show the feasibility of the proposed solution for a future practical application. This research has been carried out in the framework of the Italian Defence Research National Program for the development of `dual use' technologies.","PeriodicalId":412230,"journal":{"name":"2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127798377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combing the ignition characteristics and demands specifically for the FPLG system, the breakdown voltage and conduction duration of the primary coil are determined theoretically with the Townsend and Paschen Laws. A computational fluid dynamics (CFD) mode is developed to investigate the in-cylinder pressure and temperature at various igniting moments. The theoretical minimum ignition energy is determined with the laminar combustion theory, which contributes to the design and optimization of the sparking system. The effects of the ignition points and initial in-cylinder temperature on the breakdown voltage and minimum ignition energy are analyzed. The results show that advanced ignition contributes to decreasing the breakdown voltage and the conduction duration of the primary coil, meanwhile has no negative influence on the minimum ignition energy. However, rising initial in-cylinder temperature lowers the breakdown voltage, shortens the conduction duration of the primary coil and reduces the minimum ignition energy.","PeriodicalId":412230,"journal":{"name":"2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130077648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
