spatial perception and Operational Behavior of drivers in approaching to an obstacle
Systems Man and Cybernetics, 2020Co-Authors: Shintaro Kawai, Masakazu Hirokawa, Naohisa Uesugi, Satoru Furugori, Toshihiro Hara, Kenji SuzukiAbstract:This study aims for the new driving skill improvement support system based on driving skill evaluation. We try to define driving skill in terms of "spatial perception" and "prediction". This research can be roughly divided into two steps. The first step is to establish an objective skill evaluation model. The second step is to verify effects of the support system for driving skill improvement. In this paper, we describe that we evaluated driving skill based on parking performance, Operational Behavior like steering and cognitive Behavior like head motion and gazing points. We conducted driving Behavior measurement experiment by using a real vehicle to get Operational and cognitive data during driving. In consequence, we confirmed that driving skill could be defined by spatial perception and Operational Behavior of drivers in approaching to an obstacle.

Modeling Operational Behavior of plug-in electric vehicles' parking lot in multi-energy systems
2016 IEEE PES Transmission and Distribution Conference and Exposition (T&D), 2016Co-Authors: Maziar Yazdani-damavandi, Miadreza Shafie-khah, Mohsen Parsa Moghaddam, Mahmoud-reza Haghifam, Joao P. S. CatalaoAbstract:Development of distributed energy resources (DER) introduces high level of interdependency and the need for integrated models in a multi-energy system (MES). Moreover, highlighting environmental aspects facilitates electrification in the transportation sector and integration of plug-in electric vehicles (PEV). In this paper, aggregation of PEVs' batteries in parking lots (PL) is considered as a bulk electric storage in MES. The energy hub approach is employed for modeling MES considering PL. Due to the profitable Behavior of PL in the reserve market, the energy hub model is modified to consider the reserve sources as ancillary services in the output energy vector. Moreover, the uncertain traffic pattern of PEVs' owners in PL is modeled by a stochastic approach. The numerical results demonstrate the proficiency of the proposed model, determining the changes in the Behavior of other MES's elements in the presence of PL.

Impacts of participating in different demand response programs on Operational Behavior of plug-in electric vehicle parking lots
Proceedings - 2015 International Symposium on Smart Electric Distribution Systems and Technologies EDST 2015, 2015Co-Authors: Miadreza Shafie-khah, Fabio A.s. Gil, Jamshid Aghaei, Joao P. S. Catalao, Mostafa BaraniAbstract:With increasing environmental concerns, the electrification of\ntransportation plays an outstanding role in the sustainable development.\nIn this context, plug-in electric vehicle and demand response have\nindispensable impacts on future smart grid. Since integration of\nelectric vehicles into the grid is a key element to achieve sustainable\nenergy systems, this paper studies the Behavior of plug-in electric\nvehicle parking lots in the electricity markets. Participation of these\nnew market players, as responsive demands, is modeled in both\nprice-based and incentive-based demand response programs. Moreover,\nimpacts of different demand response programs on optimal Operational\nBehavior of the parking lots are investigated. In addition to\nuncertainties of activated reserve, uncertainties of electric vehicle\nclass, arrival and departure times, and initial battery state-of-charge\nare also considered. Stochastic programming is used to address the\nmentioned uncertainties. Numerical studies indicate that the\nparticipation of parking lots in different demand response programs can\nincrease their profit.

Symbolic model checking composite Web services using Operational and control Behaviors
Expert Systems with Applications, 2013Co-Authors: Jamal Bentahar, Hamdi Yahyaoui, Melissa Kova, Zakaria MaamarAbstract:This paper addresses the issue of verifying if composite Web services design meets some desirable properties in terms of deadlock freedom, safety (something bad never happens), and reachability (something good will eventually happen). Composite Web services are modeled based on a separation of concerns between business and control aspects of Web services. This separation is achieved through the design of an Operational Behavior, which defines the composition functioning according to the Web services' business logic, and a control Behavior, which identifies the valid sequences of actions that the Operational Behavior should follow. These two Behaviors are formally defined using automata-based techniques. The proposed approach is model checking-based where the Operational Behavior is the model to be checked against properties defined in the control Behavior. The paper proves that the proposed technique allows checking the soundness and completeness of the design model with respect to the Operational and control Behaviors. Moreover, automatic translation procedures from the design models to the NuSMV model checker's code and a verification tool are reported in the paper.

Operational Behavior and Reforming Kinetics over Ni/YSZ of a Planar Type Pre-Reformer for SOFC Systems
International Journal of Hydrogen Energy, 2014Co-Authors: Van Nhu Nguyen, Ludger Blum, Roland PetersAbstract:Abstract At Forschungszentrum Julich GmbH, a multi-component SOFC design based on planar stacks has been developed, in which all hot system components are scaled to a nominal SOFC stack power of 5 kW. To optimize the SOFC system it is necessary to investigate the effects of design and operating parameters on the system components like pre-reformer and afterburner. A special designed 5-layer planar type steam pre-reformer on basis of Ni/YSZ has been built and tested for Operational Behavior and kinetics of steam reforming with methane. This paper summarizes and discusses the experimental results on the global reaction kinetics of a Julich planar pre-reformer in the temperature range between 350 °C and 620 °C at ambient pressure (1 bar). The species compositions of product gas at different feed compositions, flow rates and temperatures are determined by using gas-chromatographic methods and dew-point measurements. The reproducibility of experiments in the low temperature range (especially less than 430 °C) was only assured, when the catalyst has been reduced before every kinetic experiment. The proposed kinetic expression of Arrhenius type (second order with respect to mole fraction of methane and first order with respect to mole fraction of water) gives a good agreement with the experimental results of the methane steam reforming. It is general effective for different steam to carbon ratios. The temperature distribution in the pre-reformer and the loss of heat are also discussed.
