Devices with ZnCdS/ZnS heterojunction partner layer have shown better blue photon response due to higher band gap of these compounds as compared to devices with CdS heterojunction partner layer. CdS heterojunction partner layer has shown high photovoltaic conversion efficiencies with CIGS absorber layer while efficiencies are lower with CuIn1-xGaxS2 (CIGS2). A negative conduction band offset has been observed for CdS/CIGS2 as compared to near flat conduction band alignment in case of CdS/CIGS devices, which results in higher interface dominated recombination. Moreover, it has been predicted that optimum band offsets for higher efficiency solar cells may be achieved for cells with alternative heterojunction partner such as ZnS. With varying ratio of Zn/ (Zn+Cd) in ZnxCd1-xS a range of bandgap energies can be obtained and thus an optimum band offset can be engineered. For reducing interface dominated recombination better lattice match between absorber and heterojunction partners is desirable. Although CdS has better lattice match with CuIn1-xGaxS2 absorber layer, same is not true for CuIn1-xGaxS2 absorber layers. Utilizing ZnxCd1-xS as heterojunction partner provides a range of lattice constant (between aZnS= ~5.4 Ǻ and aCdS= ~5.7 Ǻ) depending on Zn/(Zn+Cd). Therefore better lattice match can be obtained between heterojunction partner and absorber layer. Better lattice match will lead to lower interface dominated recombination, hence higher open circuit voltages. In the present study chemical bath deposition parameters are near optimized for high efficiency CIGS2 Solar cells. Effect of various chemical bath deposition parameters on device performance was studied and attempts were made to optimize the deposition parameters in order to improve the device performance.In/(In+Ga) ratio in absorber layer is varied to obtain good lattice match and optimum band alignment. Solar cells with conversion efficiencies comparable to conventional CdS/CIGS2 has been obtained with ZnxCd1-xS /CIGS2. High short current as well as higher open circuit voltages were obtained with ZnxCd1-xS as alternative heterojunction partner for CIGS2 solar cells as compared to SLG/Mo/CIGS2/ CdS / i-ZnO/ZnO:Al.

Title: Mission Impossible? A case study on how to manage the tension between openness and secrecy in the defense industry. Background: This thesis is built upon a unique case exhibiting open innovation within the defense industry. Practicing open innovation is a challenge for all organizations today but as a consequence of the defense industry’s high secrecy, open innovation becomes even more challenging. On one hand, they need to share internal knowledge to practice open innovation but on the other hand, sharing too much can endanger its country’s national security. The tension emerging from the need to open up an organization to practice open innovation while simultaneously maintaining secrecy results in an emergence of paradoxical tension. The literature has highlighted this tension as the paradox of openness. Purpose Research the paradox of openness within the defense industry. Methodology: An abductively qualitative single case study at the Swedish defense company Saab AB. The empirical data were collected from13 semi-structured and unstructured interviews. Findings: Selective revealing, a strong relationship and trust, internal rules and processes, and the understanding of customer capabilities are ways defense organizations can use to manage the paradox of openness in offset agreements. Keywords: Open innovation, The paradox of openness, Differentiation and integration approach, Defense industry, Saab AB, Offset, Transfer of Technology, Brazil.

In March 2011, the European Commission submitted a proposal for a Council Directive on an optional common consolidated corporate tax base (CCCTB). If this proposed CCCTB system comes into force, taxes calculated under the currently existing system of separate accounting might be replaced by a system of group consolidation and formulary apportionment. Then, multinational groups (MNGs) would face the decision as to whether to opt for the CCCTB system. Prior research focuses mainly on the differences in economic behaviour under both systems in general. By con-trast, we study the conditions under which one or the other tax system is preferable from the per-spective of an MNG, with a particular focus on loss-offsets. We identify four effects that determine the decision of an MNG: the tax-utilization of losses, the allocation of the tax base, the dividend and intragroup interest taxation. We find mixed results, e.g., that the CCCTB system proves ad-vantageous for increasing loss/profit streams (e.g. from start-ups or R&D projects) of the individual group entities, whereas the system of separate accounting is beneficial for decreasing profit/loss streams (e.g. caused by a decrease in return from a mature product). The results of our analysis are helpful for MNGs facing the decision as to whether to opt for the CCCTB system and can also support legislators and politicians in the EU but also in other regions in their tax reform discussions.

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / The Nova HYPERMOD demodulator operates in three modes, the classic pulse-code modulation/frequency modulation (PCM/FM), sometimes known as continuous phase frequency shift keying (CPFSK) mode, shaped offset quadrature phase shift keying (SOQPSK) mode, and continuous phase modulation (CPM) mode. Of interest to this paper is SOQPSK mode which is a waveform similar to the Advanced Range Telemetry (ARTM) Tier I waveform, Feher’s Quadrature Phase Shift Keying, B version (FQPSK-B) revision (Rev) A1. Also considered is another variant, FQPSK-JR. This paper will outline the cross compatibility and resynchronization speed of these waveforms based upon ARTM-adopted demodulator performance tests. The results of these laboratory tests comparing the HYPERMOD demodulator, the enhanced Tier I demodulator, and the current Tier I reference demodulator, both from RF Networks, will be presented.

An experimental study was designed to investigate the effect of different parameters on the development and structure of turbulent 3D offset jets. The present investigation considered the effects of offset height ratio, expansion ratio, surface roughness and rib placement on the flow dynamics of a turbulent 3D offset jet. The velocity measurements were performed using an acoustic Doppler velocimetry (ADV) and particle image velocimetry (PIV). Measurements were conducted within the symmetry and lateral planes. For the PIV technique, the measurements in the symmetry and lateral planes were conducted over a streamwise range of 0 ≤ x/bo ≤ 80 and 12 ≤ x/bo ≤ 60, respectively (where bo is the nozzle height). Likewise, velocity measurements using the ADV technique were conducted over a range of 4 ≤ x/bo ≤ 45 in both the symmetry and lateral planes. The velocity measurements were analyzed using both one-point and multi-point statistics. The one-point statistics included profiles of the mean velocities, Reynolds stresses and some of the budget terms in the turbulent kinetic energy transport equation. The quadrant analysis technique was used to investigate the dominant events that contribute towards the Reynolds shear stress. The two-point correlation analysis was used to investigate how the turbulence quantities are correlated. Information obtained from the two-point correlation analysis was also used to investigate the inclination of vortical structures within the inner and outer shear layers of the 3D offset jet. The direction of the positive mean shear gradient played an active role in the inclination of these vortical structures within the inner and outer shear layers. The reattachment process resulted in the breakdown of these structures within the developing region. Similarly, various length scales were estimated from these structures. The proper orthogonal decomposition was used to examine the distribution of the turbulent kinetic energy within the offset jet flow. Also, the dynamic role of the large scale structures towards the turbulent intensities, turbulent kinetic energy and Reynolds shear stress was investigated. / October 2016

The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. The work covers laboratory studies, a pilot coating trial designed to produce coated material with a span in surface chemistry and structure, and an industrial offset printing trial. The lab scale studies quantified ink-paper coating adhesion failure during ink setting with a developed laboratory procedure based on the Ink-Surface Interaction Tester (ISIT) and image analysis. Additional polyacrylate dispersant resulted in slower ink setting and reduced ink-paper coating adhesion, with a dependence on its state of salt neutralisation and cation exchange, mainly in the presence of moisture/liquid water. The industrial printing trial on pilot coated papers was designed to study how these laboratory findings affected full scale offset print quality. These trials confirmed the dispersant-sensitive effect on ink-paper coating adhesion, especially at high water feeds. Evaluation of prints from the printing trial resulted in two fundamentally different types of ink adhesion failure being identified. The first type being traditional ink refusal, and the second type being a novel mechanism referred to as ink-lift-off adhesion failure. Ink-lift-off adhesion failure occurs when ink is initially deposited on the paper but then lifted off in a subsequent print unit. In this work, ink adhesion failure by this ink-lift-off mechanism was observed to occur more often than failure due to ink refusal. Print quality evaluation of the industrial prints suggested that water induced mottle was caused by a combination of ink-surface adhesion failure, creating white spots on the print, together with variation in ink layer thickness due to emulsified ink. / <p>QC 20161019</p>

Malgré ce que l’on a pu croire, le régime commun pourrait présenter un grand intérêt pour le droit international de l’environnement sous réserve de la prise en compte de certaines considérations environnementales. Il s’agit d’une part, du déclenchement de la responsabilité et, d’autre part, de la réparation. Si, en raison de certaines insuffisances normatives environnementales, l’engagement de la responsabilité pourrait soulever des difficultés, le fondement du régime commun, à savoir le fait illicite, facilite la prévention des dommages environnementaux. Quant à l’invocation de la responsabilité, une évolution concernant les droits des États agissant pour un intérêt collectif pourrait empêcher que de nombreux espaces et espèces échappent à la sphère de la responsabilité des États. Concernant les modalités de la réparation, l’importance d’une réparation en nature ou par équivalent en nature impose une adaptation à l’appréciation ou à la mise en œuvre de la restitution et de l’indemnisation. En revanche, la présente thèse propose une nouvelle forme de satisfaction : la compensation écologique. / Despite some authors’ scepticism, the international environmental law can find certain solutions in the law of state responsibility. However, the success of finding such solutions depends on the introduction of a number of environmental considerations to as conditions of state responsibility, its invocation and reparation. Regarding the first, although the state responsibility, which is based on breach of obligations, may lack normative environmental aspect, its preventive role vis-a-vis the environmental harm should not be underestimated. As to the invocation, the positive law has to acknowledge the right of an injured state acting for the collective interest in order to include spaces and species beyond the state’s sovereignty to the law of state responsibility. Regarding the forms of reparation, restitution and compensation must be adapted taking into consideration the importance of environmental restoration towards baseline conditions. However, satisfaction needs to transform into a multiform and flexible form of reparation. For this purpose the present study suggests the biodiversity offset mechanism as a form of satisfaction.

Tentant d’accommoder protection de l’environnement et artificialisation de la nature, les mesures de compensation consistent techniquement à rééquilibrer un dommage écologique par un gain écologique. Imposées juridiquement dans les années 1970, la place de ces dispositifs interroge toujours. Mesures de police administrative par nature, elles s’assimilent à un mode de réparation en dehors de tout régime de responsabilité par leur finalité : remédier en nature aux atteintes causées aux milieux naturels. Échappant à toute définition en dépit de la variété des régimes juridiques actuels, les compensations à visée écologique demeurent inabouties sur le plan juridique. De cette hétérogénéité des régimes juridiques, peut-il émerger un concept unique propre à garantir sa nature curative ? Leur vocation commune est desservie par les indéterminations juridiques dont souffrent ces compensations et qui résident tant dans la pluralité juridique des compensations que dans les défaillances pratiques lors de leur mise en œuvre. Se créé alors un hiatus entre les décisions prises fondées sur une compensation idéalisée, à savoir un instrument de lutte contre la perte de biodiversité, et la réalité des mesures le plus souvent sans équivalence écologique, précaires voire inexistantes. C’est pourquoi il convient de mettre fin à cet amalgame grâce à une caractérisation juridique de ce que devrait être la compensation écologique. Cette tentative de définition s’accompagne d’une exploration des perspectives d’avenir de la compensation écologique notamment sous l’angle d’une mutualisation des sites de compensation. / The aim of ecological offsets is to combine environmental protection with the social and economic opportunities of implementing new projects on natural spaces. Technically, these measures involve restoring balance between ecological damages and ecological benefits to be provided for by the ecological offset. Ecological offsets measures became mandatory in the seventies, yet their adequacy is still questioned today. They are administrative policy measures, distinct from liability. Although several different ecological offsets exist, no law explicitly defines them. It appears then very important to know whether it’s possible to draw one global legal definition of ecological offset, in order to assure the achievement of the ecological goals of all this measures: providing effective reparation of the damages caused to the ecosystems. All the more as the lack of legal offset criteria is adding to already existing practical difficulties which may in term bring about the downfall of ecological offset.Actually, though it is widely presented as a legal instrument to reverse the loss of biodiversity; reality shows that this purpose may not be attained, especially because of a lack of unanimous ecological measurement model. That’s why ecological offset deeply needs a legal characterization of what it should be. After this attempt at a definition, the thesis proposes to explore the future of the ecological offset, including the opportunities offered by shared sites of natural remediation.
