  • Monitoring active species in an atmospheric pressure dielectric-barrier
           discharge: Observation of the Herman-infrared system
    • Authors: Adriana Annušová; Peter Čermák, Jozef Rakovský, Viktor Martišovitš, Pavel Veis
      Abstract: An electronic and spectroscopic study of dielectric-barrier discharge transition from the Townsend to the filamentary mode is presented. The discharge is generated under pure nitrogen flow at atmospheric pressure in a reactor with parallel configuration of cylindrical electrodes covered with Al2O3 dielectrics, applying a frequency of 4.85 kHz. The goal of the study was to find optimal conditions for observation of the Herman-infrared (HIR) transition (C”5Πu+ A'5Σg+) in a perspective to develop and test a ro-vibrational model for this quintet band. We have focused on finding the maximum emissivity of the HIR transition in the homogeneous discharge regime as it offers a more suitable source for calibrating the HIR model. Besides the capability of generating a spatially homogeneous type of radiation, our discharge design also allowed the observation of HIR without detectable interference from the first positive system of nitrogen which is not common for atmospheric pressure discharges. In the study, a time-resolved observation of the NOγ system, the second positive and the HIR nitrogen systems were performed and their emissivities analysed as a function of the discharge period and power. The optimum for the observation of the HIR system was found at 2.94 W (power density of 6 W/cm3), corresponding to the Townsend discharge just before its transition to the filamentary one.

  • Production of long, laminar plasma jets at atmospheric pressure with
           multiple cathodes
    • Authors: Cheng Wang; Haichao Cui, Zelong Zhang, Weiluo Xia, Weidong Xia
      Abstract: Plasma jets from conventional non-transferred arc plasma devices are usually operated in turbulent flows at atmospheric pressure. In this paper, a novel non-transferred arc plasma device with multiple cathodes is introduced to produce long, laminar plasma jets at atmospheric pressure. A pure helium atmosphere is used to produce a laminar plasma jet with a maximum length of >60 cm. The influence of gas components, arc currents, anode nozzle diameter, and gas flow rate on the jet characteristics is experimentally studied. The results reveal that the length of the plasma jet increases with increasing helium content and arc current but decreases with increasing nozzle diameter. As the gas flow rate increases, the length of the plasma jet initially increases and then decreases. Accordingly, the plasma jet is transformed from a laminar state to a transitional state and finally to a turbulent state. Furthermore, the anode arc root behaviours corresponding to different plasma jet flows are studied. In conclusion, the multiple stationary arc roots that exist on the anode just inside the nozzle entrance are favourable for the generation of a laminar plasma jet in this device.

  • Heat flow through a plasma sheath in the presence of secondary emission
           electron from plasma–wall interaction
    • Authors: Jing Ou; Xiaoyun Zhao
      Abstract: The formation of a plasma sheath in front of a negative wall emitting secondary electron is studied by a one-dimensional fluid model. The model takes into account the effect of the ion temperature. With the secondary electron emission (SEE) coefficient obtained by integrating over the Maxwellian electron velocity distribution for various materials such as Be, C, Mo, and W, it is found that the wall potential depends strongly on the ion temperature and the wall material. Before the occurrence of the space-charge-limited (SCL) emission, the wall potential decreases with increasing ion temperature. The variation of the sheath potential caused by SEE affects the sheath energy transmission and impurity sputtering yield. If SEE is below SCL emission, the energy transmission coefficient always varies with the wall materials as a result of the effect of SEE, and it increases as the ion temperature is increased. By comparison of with and without SEE, it is found that sputtering yields have pronounced differences for low ion temperatures but are almost the same for high ion temperatures.

  • Nonlinear Waves in Nonuniform Complex Astrocloud
    • Authors: A. Haloi; P. K. Karmakar
      First page: 5
      Abstract: The global nonlinear gravito-electrostatic eigen-fluctuation behaviors in large-scale non-uniform complex astroclouds in quasi-neutral hydrodynamic equilibrium are methodologically analyzed. Its composition includes warm lighter electrons, ions; and massive bi-polar multi-dust grains (inertial) with partial ionization sourced, via plasma-contact electrification, in the cloud plasma background. The multi-fluidic viscous drag effects are conjointly encompassed. The naturalistic equilibrium inhomogeneities, gradient forces and nonlinear convective dynamics are considered without any recourse to the Jeans swindle against the traditional perspective. An inho-mogeneous multiscale analytical method is meticulously applied to derive a new conjugated non-integrable coupled (via zeroth-order factors) pair of variable-coefficient inhomogeneous Korteweg de-Vries Burger (i -KdVB) equations containing unique form of non-uniform linear self-consistent gradient-driven sinks. A numerical illustrative scheme is procedurally constructed to examine the canonical fluctuations. It is seen that the eigenspectrum coevolves as electrostatic rarefactive damped oscillatory shock-like structures and self-gravitational compressive damped oscillatory shock-like patterns. The irregular damping nature is attributable to the i -KdVB sinks. The aperiodicity in the hybrid rapid small downstream wavetrains is speculated to be deep-rooted in the quasi-linear gravito-electrostatic interplay. The phase-evolutionary dynamics grow as atypical non-chaotic fixed-point attractors. We, finally, indicate tentative astronomical applications relevant in large-scale cosmic structure formation aboard facts and faults. (© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

  • Study on a New Ignition Method of the Spark Gap Based on Plasma Ejection
           in Air
    • Authors: D. Huang; L.J. Yang, P. Huo, J.B. Ma, S. Liu, W. Wang, W.D. Ding
      First page: 20
      Abstract: A new ignition method of the spark gap based on plasma ejection is proposed in this paper, as the conventional trigatron spark gap performs poorly under the low working coefficient (the ratio of the charging voltage to the self‐breakdown voltage) in air. The plasma is generated by the capillary discharge, which has high pressure, high temperature and high velocity. The capillary discharge device is placed inside the low voltage electrode. As long as the triggering signal is sent to the device, a column of the plasma flow is ejected in axial direction and develops rapidly towards the high voltage electrode. Subsequently, the gap is broken down and a high resistive channel is formed, where the thermal ionization takes place and the arc across the whole gap is generated and develops into a well conductive channel. The process of the thermal ionization of the high resistive channel varies with the change of the spark gap distance. The breakdown delay and the delay jitter of the spark gap increase with the spark gap distance, as both parameters are mainly determined by the developing process of the plasma ejection. The characteristics of the plasma flow determine the possibility of the breakdown of the spark gap under the low working coefficient. The ignition method based on capillary plasma ejection has been proved by the preliminary experiments, which indicate that under the gap length of 8 cm and the working coefficient of less than 3%, the effective ignition is still achievable.

  • THz Radiation Generation via the Interaction of Ultra-short Laser Pulses
           with the Molecular Hydrogen Plasma
    • Authors: M. S. Soltani Gishini; A. Ganjovi, M. Saeed
      First page: 29
      Abstract: In this paper, a two dimensional Particle In Cell-Monte Carlo Collision simulation scheme is used to examine the THz generation via the interaction of high intensity ultra-short laser pulses with an underdense molecular hydrogen plasma slab. The influences of plasma density, laser pulse duration and its intensity on the induced plasma current density and the subsequent effects on the generated THz signal characteristics are studied. It is observed that the induced current density in the plasma medium and THz spectral intensity are increased at the higher laser pulse intensities, laser pulse durations and plasma densities. Moreover, the generated THz electric field amplitude is reduced at the higher laser pulse durations. A wider frequency range for the generated THz signal is shown at the lower laser pulse durations and higher plasma densities. Additionally, it is found that the induced current density in hydrogen plasma medium is the dominant factor influencing the generation of THz pulse radiation. (© 2016 WILEY-VCH Verlag GmbH & Co.

      Abstract: An absolutely straightforward study is presented to characterize the space-charge limited region in a planar diode with non-zero uniform initial velocity which brings about Liu's result. Unlike Liu's work, our approach is free of mathematical intricacies. In addition to its great simplicity, the presented method gives a good physical insight about the problem.

  • Individual Creativity and Team Climate in Software Development Projects:
           The Mediating Role of Team Decision Processes
    • Authors: Atif Açıkgöz; Ayşe Günsel
      Pages: 445 - 463
      Abstract: This study investigates how individual creativity is related to the quality of team decision processes and team climate, and the mediating role of team decision processes between individual creativity and team climate. A multi-level theoretical model was proposed and partial least squares structural equation modelling (PLS-SEM) was conducted on a sample of 139 software development projects. The results suggest that: (i) individual creativity improves the quality of team decision processes, (ii) team decision processes are positively associated with four dimensions of team climate (organizational support, innovation orientation, goal orientation and informal structure), and (iii) team decision processes partially mediate between individual creativity and team climate. In particular, the obtained results stress the role of individual creativity in the formation and evolution of a positive climate by means of team decision processes. The study implies that managers should recognize the value of creative individuals as the basic source of competitive advantage and success. It further discusses the managerial implications of the findings as well as limitations and constructive new directions for future studies to improve software development team performance.

  • Gambling versus Designing: Organizing for the Design of the Probability
           Space in the Energy Sector
    • Authors: Sophie Hooge; Olga Kokshagina, Pascal Le Masson, Kevin Levillain, Benoit Weil, Vincent Fabreguettes, Nathalie Popiolek
      Pages: 464 - 483
      Abstract: The objective of this paper is to elucidate an organizational process for the design of generic technologies (GTs). While recognizing the success of GTs, the literature on innovation management generally describes their design according to evolutionary strategies featuring multiple and uncertain trials, resulting in the discovery of common features among multiple applications. This random walk depends on multiple market and technological uncertainties that are considered exogenous: as smart as he can be, the ‘gambler’ must play in a given probability space. However, what happens when the innovator is not a gambler but a designer, i.e., when the actor is able to establish new links between previously independent emerging markets and technologies? Formally speaking, the actor designs a new probability space. Building on a case study of two technological development programmes at the French Center for Atomic Energy, we present cases of GTs that correspond to this logic of designing the probability space, i.e. the logic of intentionally designing common features that bridge the gap between a priori heterogeneous applications and technologies. This study provides another example showing that the usual trial-and-learning strategy is not the only strategy to design GTs and that these technologies can be designed by intentionally building new interdependences between markets and technologies. Our main result is that building these interdependences requires organizational patterns that correspond to a ‘design of exploration’ phase in which multiple technology suppliers and application providers are involved in designing both the probability space itself and the instruments to explore and benefit from this new space.

           Design Innovation Capabilities
    • Authors: Paolo Landoni; Claudio Dell'Era, Gregorio Ferraloro, Mattia Peradotto, Helena Karlsson, Roberto Verganti
      Pages: 484 - 499
      Abstract: The strategic role of design-driven innovation is being increasingly recognized. Many studies show that investments in design positively influence the innovative capacity of firms and consequently their competitive performance. However, few researchers have explored how this relationship comes about. The studies that over the years have contributed to the understanding of design have identified two main barriers: the lack of a common language on design, and poor analysis of the dynamics that characterize the relationship between investment in design and competitive performance. In this paper, we investigate six small and medium-sized enterprises (SMEs) located in the Lombardy region of Italy that have received funding from a policy aimed to develop design innovation capabilities. We identify and discuss five different design innovation capabilities and we analyse their role in mediating the relationship between investment in design and competitive performance.

  • Managing Controversies in the Fuzzy Front End
    • Authors: John K. Christiansen; Marta Gasparin
      Pages: 500 - 514
      Abstract: This research investigates the controversies that emerge in the fuzzy front end (FFE) and how they are closed so the innovation process can move on. The fuzzy front has been characterized in the literature as a very critical phase, but controversies in the FFE have not been studied before. The analysis investigates the microprocesses around the controversies that emerge during the fuzzy front end of four products. Five different types of controversies are identified: profit, production, design, brand and customers/market. Each controversy represents a threat, but also an opportunity to search for new solutions in the unpredictable non-linear processes. The study uses an ethnographic approach using qualitative data from interviews, company documents, external communication and marketing material, minutes of meetings, informal conversations and observations. The analysis of four FFE processes demonstrates how the fuzzy front requires managers to deal with controversies that emerge from many different places and involve both human and non-human actors. Closing the controversies requires managers to take account of the situation, identify the problem that needs to be addressed, and initiate a search for solutions. Management is actively involved in this process, in many different ways. Among the implications from this analysis is that the managers' role in the FFE is multifaceted and each controversy seems to require different skills and competencies.

  • Social Conduct, Learning and Innovation: An Abductive Study of the Dark
           Side of Agile Software Development
    • Authors: Maria Carmela Annosi; Mats Magnusson, Antonella Martini, Francesco Paolo Appio
      Pages: 515 - 535
      Abstract: Agile methodologies have been adopted by an increasing number of organizations to improve their responsiveness. However, few studies have empirically analysed the effect of Agile on long-term organizational goals such as learning and innovation. Using an abductive approach, this study examines the relationships between self-regulated teams' social conduct and their resulting learning and innovation. Results indicate that the time pressure induced by the implementation of Agile impedes team engagement in learning and innovation activities. Time pressure is affected by a set of different control strategies, more specifically concertive, belief, diagnostic and boundary controls, and these need to be adequately addressed in order to minimize the potential dark side of Agile.

  • Democratizing Journalism – How User-Generated Content and User
           Communities Affect Publishers’ Business Models
    • Authors: Michael A. Zeng; Bianca Dennstedt, Hans Koller
      Pages: 536 - 551
      Abstract: Publishers, today, are struggling with their business model: Their efforts to convert traditional content into digital products seem to be insufficient as recipients expect more than simply the mere digitalization of content. Dissatisfied with solely being informed by selected journalists, modern recipients are often interested in acquiring information from various sources, in discussing with others, or even in contributing with their own content. Hence, recipients seem to evolve from being simply readers to contributors themselves. With regard to the established term ‘user-generated content’, we refer to those co-creating recipients as users. To underline these assumptions, the present study explores (1) users’ expectations of sources of content and (2) their willingness to provide their own content. Our findings show that both user-generated content and professional journalists’ content is of value to users. Second, we show that users are mainly driven to contribute by their own expertise, welfare of others, and personal acceptance in the community. With this study, we consider mainly the changed user behaviour in order to derive implications of user involvement for future business models of publishers, in particular on the customer value proposition as well as key resources and key processes.

  • The Antecedents of Individual Innovative Behaviour in Temporary Group
           Innovation
    • Authors: Anna-Maija Nisula; Aino Kianto
      Pages: 431 - 444
      Abstract: This study examines the antecedents of individual innovative behaviour in short-term innovation camp conditions. Innovation is increasingly a joint activity conducted in various kinds of temporary settings that collect widely diverse people together for a brief time to work on a particular problem. As innovativeness of interplaying individuals is key for the success of collaborative innovation, it is important to study what factors enhance individual innovative behaviour in temporary settings. Data from 103 innovation camp participants were the basis of PLS-SEM analysis. Results show that individual creative self-efficacy, perceived task orientation and experimentation have significant effects on individual innovative behaviour. In contrast, participative safety, support for innovation, and vision are not associated with individual innovativeness. These findings suggest that the antecedents of individual innovativeness in temporary settings differ from those identified in conventional groups, pointing to a new field for future research.
