Abstract:
Abstract. Earthquakes are one of the natural disasters that often occur in Indonesia, especially on the island of Sumatra. Earthquakes become a frightening spectre because they cannot be predicted when they will come, where they will be located, and how strong the vibrations are, so they often cause damage and casualties. To minimise losses due to earthquakes, it is necessary to divide areas easily affected by earthquakes. One method that can be used to divide these areas is clustering techniques. This study uses a clustering method, namely Spatio Temporal-Density Based Spatial Clustering Appl

AbstractThe spectre of music as a transcendent artistic ideal figures prominently in the literary criticism of Victorian aestheticism, though the extent to which aestheticism of the movement actually influenced the thinking of British composers has received only marginal scholarly attention. By the first decades of the twentieth century, aestheticism had become decidedly unfashionable even in literary circles, so it is unsurprising that composers of the time would choose to distance themselves from its rhetoric.

Mon article constitue une analyse du concept d’authenticité chez Jean-Jacques Rousseau. Ce qui m’intéresse particulièrement dans cette analyse c’est la triade dialectique mémoire-oubli-souvenir. Rousseau met cette triade en œuvre pour définir « le sentiment de l’existence », synonyme de l’authenticité et de la transparence des consciences humaines. Or les méfaits de la culture, dont l’homme seul est responsable en tant qu’être historique, ont défiguré cette authenticité et cette transparence primordiales.

Abstract:
The Big Trio programme was aimed to search for distant radio galaxies for the purpose of cosmological research. A selection of sources with steep and ultra-steep spectra was made from the radio sources discovered in a series of surveys by the Cold Experiment, which was carried out on the RATAN-600 radio telescope. The results of the studies of 113 sources in this sample were the optical identification of almost the entire sample, spectral studies of the majority of the objects (70%), spectral redshift determinations for half of them, and the discovery of three unique radio galaxies with redshi

Abstract:
Abstract Real-time and automatic radioisotope identification using gamma spectrum is an important issue in the field of nuclear safety. It is widely used in vehicle mounted radioisotope monitoring, Marine radioisotope monitoring and nuclear decommissioning verification scenarios. At present, the focus of radionuclide identification is fast and stable recognition under low count conditions. In this paper, a radionuclide recognition method based explainable artificial neural network is proposed, and a synthetic gamma spectrum data set is created. The data set contains gamma-ray spectra of 12 dif

Abstract:
We have investigated the resonance fluorescence spectrum from two identical atoms driven by a strong standing wave field. We found interesting modifications of the Mollow spectrum, caused by interferences between the two atoms, and in particular a succession of dark and bright states as one of the atoms is moved to successive nodes of the field. Large enough separation between the atoms leads to the disappearance of these interferences, and the atoms act then as independent radiators, the fluorescence spectrum becoming then independent of the interatomic distance.

Abstract:
It was recently shown that the spectrum of partially coherent light can change on propagation.1 So far most of the work has applied to propagation in free space and has been limited to far-zone observation points. In this paper we consider the propagation of partially coherent light through homogeneous and inhomogeneous media. Our formulation is based on the analysis of Agrawal et al.,2 which applies to graded-index fibers whose index of refraction changes quadratically as a function of the radial distance from the core center. With this formulation we derive expressions by using the paraxial

Abstract:
Commercial agriculture has come under increasing pressure to reduce nitrogen fertilizer inputs in order to minimize potential nonpoint source pollution of ground and surface waters. This has resulted in increased interest in site specific fertilizer management. One way to solve pollution problems would be to determine crop nutrient needs in real time, using remote detection, and regulating fertilizer dispensed by an applicator. By detecting actual plant needs, only the additional nitrogen necessary to optimize production would be supplied. This research aimed to develop techniques for real tim

Abstract:
"Doppler boosting / de-boosting" is a well-known relativistic effect that alters the apparent luminosity of approaching/receding radiation sources. "Doppler boosting" alters the apparent luminosity of approaching light sources to appear brighter, while "Doppler de-boosting" alters the apparent luminosity of receding light sources to appear fainter. While "Doppler boosting / de-boosting" has been successfully accounted for and observed in relativistic jets of AGN, double white dwarfs, in search of exoplanets and stars in binary systems it was ignored in the establishment of Standard Candles for

Abstract:
Diamond mining via open pit mining has been ongoing within the Tlicho region of the Northwest Territories for several decades, which includes the habitat range of the Bathurst Caribou Herd. This has led to the importance of quantitative characterization of the Zone Of Influence (ZOI), where resource development activities may be influencing the natural behaviour of the caribou herd in the tundra environment. As part of better defining and understanding the ZOI in this region, an initiative to evaluate the potential of detecting and mapping mine waste rock dust in the surrounding environment is
