    Opis:
    Ambient concentrations of CO, as well as NOx and O3, were measured as a part of the PARADE campaign conducted at the Taunus Observatory on the summit of the Kleiner Feldberg between the 8th of August and 9th of September 2011. These measurements were made in an effort to provide insight into the characteristics of the effects of both biogenic and anthropogenic emissions on atmospheric chemistry in the rural south-western German environment. The overall average CO concentration was found to be 100.3±18.1 ppbv (within the range of 71 to 180 ppbv), determined from 10-min averages during the summer season. The background CO concentration was estimated to be ~90 ppbv. CO and NOx showed bimodal diurnal variations with peaks in the late morning (10:00-12:00 UTC) and in the late afternoon (17:00-20:00 UTC). Strong correlations between CO and NOx indicated that vehicular emission was the major contributor to the notable CO plumes observed at the sampling site. Both local meteorology and backward trajectory analyses suggest that CO plumes were associated with anthropogenically polluted air masses transferred by an advection to the site from densely populated city sites. Furthermore, a good linear correlation of R2 = 0.54 between CO and O3 (∆O3/∆CO=0.560±0.016 ppbv/ppbv) was observed, in good agreement with previous observations.

    Opis:
    Line current differential (87L) protection schemes face extra challenges compared with other forms of differential protection, in addition to the traditional requirements of sensitivity, speed, and immunity to current transformer saturation. Some of these challenges include data communication, alignment, and security; line charging current; and limited communications bandwidth. To address these challenges, microprocessor-based 87L relays apply elaborate operating characteristics, which are often different than a traditional percentage differential characteristic used for bus or transformer protection. These sophisticated elements may include adaptive restraining terms, apply an Alpha Plane, use external fault detection logic for extra security, and so on. While these operating characteristics provide for better performance, they create the following challenges for users: x Understanding how the 87L elements make the trip decision. x Understanding the impact of 87L settings on sensitivity and security, as well as grasping the relationship between the traditional percentage differential characteristic and the various 87L operating characteristics. x Having the ability to transfer settings between different 87L operating characteristics while keeping a similar balance between security and dependability. x Testing the 87L operating characteristics. These issues become particularly significant in applications involving more than two currents in the line protection zone (multiterminal lines) and lines terminated on dual-breaker buses. This paper is a tutorial on this relatively new protection topic and offers answers to the outlined challenges.

    Opis:
    It has been claimed by Patil et al., that Ce$\text{}_{3}$Cu$\text{}_{3}$Sb$\text{}_{4}$ is the first Ce-based semiconducting ferromagnet. In this paper it is shown, mainly with Hall effect and far infrared spectroscopy that no gap in the excitation spectrum exists, as well above as below the magnetic ordering temperature. A maximum in the resistivity near T$\text{}_{C}$ is due to trapped magnetic polarons. The resistivity is an effect of the mobility of the charge carriers. The structure of the magnetic unit cell has been determined with elastic neutron scattering.

    Opis:
    We investigated the n-type doping of the wide-gap II-VI semiconductor (CdMg)Te. The n-type doping of (CdMg)Te has previously been achieved in only a small range of magnesium concentration. By the use of zinc iodine as dopant source material, we obtained highly doped (CdMg)Te layers up to a magnesium concentration of 40%. The limiting factor for the free carrier concentration at room temperature is the occurrence of a deep level, which dominates the electrical properties at room temperature of layers with more than 30% magnesium. Compensating defects or defect complexes are considered, to explain the observed properties of the deep level, which do not seem to be characteristic of an isolated donor state.

    Opis:
    Rapidly increasing numbers of ships and ship sizes pose an ever-growing challenge to the maritime industry. Although statistics indicate improved levels of safety in the industry which carries 90% of the world’s trade, the risk of navigational accidents, among other issues, remains a prime concern and priority (EMSA, 2010; 2014). In order to address these concerns, the authors turned to another high-risk industry for inspiration. Specifically, they turned to the aviation industry, which has often been used as a source of comparisons and ideas by researchers in the maritime domain. Keeping up with the trend, the authors of this paper turn to a tried-and-tested system used widely in modern aviation: the Airborne Collision Avoidance System (ACAS). The prime idea behind ACAS is to construct two virtual 3D zones around an aircraft. These zones are dynamic, and depend on the manoeuvring characteristics of a given aircraft. If the system detects an “intruder” (another aircraft) in either of the two well-defined virtual zones, it provides warnings and/or instructions to pilots of both aircraft to take certain precautionary or emergency measures. In the current paper, the authors explore whether or not such a system is feasible for use in the maritime domain and, if so, how. The paper provides a detailed analysis of the potential benefits and drawbacks of using an ACAS-like system onboard vessels. It also discusses possible means of implementation and integration with current equipment, and explores how the introduction of e-navigation may impact the proposed solution.

    Opis:
    We have performed photoluminescence measurements in order to study the optical properties of hydrogenated GaAs$\text{}_{1-y}$N$\text{}_{y}$/GaAs heterostructures for y ranging from 0 to 0.03. Hydrogen irradiation leads to: (i) a progressive passivation of N-related recombination lines for low N content (y≈ 0.001); (ii) a sizable blue shift of the band gap in the "alloy" limit (y≈0.01). Thermal annealing restores the optical properties samples had before hydrogenation. These results can be accounted for by the formation of N$\text{}^{-}$ -H$\text{}^{+}$ complexes and demonstrate that hydrogen irradiation provides a powerful tool for the analysis of photoluminescence spectra of GaAs$\text{}_{1-y}$N$\text{}_{y}$.

    Opis:
    The effects of atomic hydrogen irradiation on the optical properties of (InGa)(AsN) single quantum wells investigated by means of photoluminescence spectroscopy. For increasing hydrogen dose, the photoluminescence band peak energy of each nitrogen-containing sample blue-shifts and for high hydrogen dose it reaches that of a corresponding nitrogen-free reference sample. This effect is accompanied by a broadening of the photoluminescence band line width and by a decrease in the photoluminescence efficiency. Thermal annealing at 550ºC fully restores the original band gap value and the photoluminescence line width of the sample before hydrogenation. An interpretation of these phenomena is proposed in terms of an H perturbation of the charge distribution around the strongly electronegative N atoms, leading most likely to the formation of H-N complexes, and to an ensuing electronic passivation of nitrogen.
