    Using the X-ray Emission Lines of Seyfert 2 AGN to Measure Abundance Ratios

    Full text link
    We measure the metal abundance ratios in the X-ray photoionized gas located near the narrow line region of a sample of Seyfert 2 AGN. The high-resolution X-ray spectra observed with the Chandra high- and low-energy transmission grating spectrometers are compared with models of the resonant scattering and recombination emission from a plasma in thermal balance, and with multiple temperature zones. The abundance ratios in the sample are close to the Solar values, with slight over-abundances of N in NGC 1068, and of Ne in NGC 4151. Our X-ray spectral models use fewer degrees of freedom than previous works.Comment: 2 pages, 1 figure, to appear in the proceedings of the conference "Multiwavelenth AGN Surveys", held in Cozumel, Mexico, December 200

    Thermodynamic modeling of micro heat engines for power generation

    No full text
    The need for compact, high power-density power sources has led to significant research interest in micro heat engines. However, there is a lack of suitable thermodynamic models which can be used to evaluate the power performance of micro heat engines by taking into consideration the effect of leakage and finite heat input. This work is the first to develop such a thermodynamic model to predict the upper limit of performance of micro heat engines. The model allows investigation of the effects of design parameters such as length and material properties on the theoretical output which can be used for design guidance. Results from this model are further illustrated by comparison to the reported P3 micro engine

    The method of decomposition for complex multivariate problems of management, based on the account of situations during the moment of acceptance of operating decisions is offered. Unlike known methods of decomposition, it does not show special requirements to structure of a problem of management. Assumes data of an initial problem of management to the modified problem considering situations, and a problem of identification of the situations, solved in common at two levels

    With the development of today's technology, information will quickly spread. Because of this, false information easily reaches the public. People who get false information often share it again without knowing that the information is fake. Therefore, this study aims to determine the level of trust of WhatsApp users in false information among the people of Batam. This quantitative research was conducted by distributing online questionnaires and as many as 326 respondents were involved in this study. The method used in this research is the regression method with the help of SPSS software. This study concludes that most people do not seem to care about the truth of the information being spread and will immediately share the information because they think the information is important for others

    Fabrication and characterisation of tellurite planar waveguides

    Tellurite glasses, which contain Tellurium dioxide as the main component, have some remarkable optical properties which are well recognised and exploited in the bulk optics and fibre fields. They include a high acousto-optic figure of merit, wide mid infrared transparency, the highest optical nonlinearity amongst oxides, and excellent rare earth hosting, etc. Despite these attractive properties, until now, no one has succeeded in fabricating low loss planar waveguides in these materials. This work develops high quality optical planar waveguides in Tellurium dioxide for the first time. The project investigates the materials science for optical Tellurium dioxide films and discovers an appropriate waveguide fabrication method. The thin films have been fabricated by reactive radio frequency magnetron sputtering using a Tellurium target in an oxygen and argon atmosphere. Propagation losses at 1550nm in the planar films are 0.1dB/cm or lower in stoichiometric composition. The properties of films have been also found to be stable with thermal annealing up to 300 degree Celsius. Plasma etching of tellurite glasses has been systematically studied. High quality etching of Tellurium dioxide and chalcogenide glass films has been demonstrated with a Methane/Hydrogen/Argon gas mixture. As a result, a fabrication recipe which produces low loss (0.1dB/cm) planar waveguides has been discovered. The nonlinear coefficient of the sputtered TeO2 has been characterised by self-phase modulation (SPM) experiments and the second order nonlinear coefficient has been measured to be around 25 times that of silica. Significant signal conversion, -4dB, has achieved with large bandwidth of 30nm in the four-wave mixing (FWM) experiment pumped at 1550nm in a slightly normal dispersion waveguide. Erbium doped Tellurium oxide thin films have also been fabricated by co-sputtering of Erbium and Tellurium targets into an Oxygen and Argon atmosphere. The obtained films have been found to have good properties for Erbium doped waveguide amplifiers. The Erbium concentration can be controlled within the range of interest with Erbium/Tellurium ratios ranging from 0.1% to 3% or more. The 1.5 micrometre photoluminescence properties of the films are excellent with effective bandwidth of more that 60nm and intrinsic lifetime of order of 3ms. Despite the fact that there was OH contamination in the films, single mode Erbium doped waveguide amplifiers with high internal gain have been successfully obtained. The 1480nm pumped amplifier achieved internal gain from below 1520nm to beyond 1600nm. The peak gain of 2.8dB/cm and 40nm 3dB gain bandwidth have been accomplished. These results are a major stepping stone towards ""system-on-chip"" optical applications for telecom and mid infrared optics given the multifunctional nature of tellurite materials. -- provided by Candidate

    As we know, the development of the furniture business in Batam City in the early twenty-first century has been developing very rapidly and is still undergoing a process of continuous development. This encourages the emergence of many new types of businesses that can become one of the threats for PT Saf Mitra Abadi. PT Saf Mitra Abadi is a company engaged in the field of furniture that has been established since 2009 in Batam City. The purpose of this study is to determine whether there is an influence between promotion, service quality and product quality partially and simultaneously on consumer purchasing decisions at PT Saf Mitra Abadi. In this study, the authors used a descriptive quantitative research method using 155 populations. In this study, the authors used the Simple Random Sampling technique in determining the population used. SPSS (Statistical Product and Service Solution) version 25 is a program used by the author to process data obtained from respondents. The results in this study indicate that there is a positive and significant influence between promotion, service quality and product quality partially and simultaneously on the consumer purchasing decisions of PT Saf Mitra Abad
