Geomorphological modelling and mapping of the Peru-Chile Trench by GMT
No full textThe author presents a geospatial analysis of the Peru-Chile Trench located in the South Pacific Ocean by the Generic Mapping Tool (GMT) scripting toolset used to process and model data sets. The study goal is to perform geomorphological modelling by the comparison of two segments of the trench located in northern (Peruvian) and southern (Chilean) parts. The aim of the study is to perform automatic digitizing profiles using GMT and several scripting modules. Orthogonal cross-section profiles transecting the trench in a perpendicular direction were automatically digitized, and the profiles visualized and compared. The profiles show variations in the geomorphology of the trench in the northern and southern segments. To visualize geological and geophysical settings, a set of the thematic maps was visualized by GMT modules: free-air gravity anomaly, geoid, geology and bathymetry. The results of the descriptive statistical analysis of the bathymetry in both segments show that the most frequent depths for the Peruvian segment of the Peru-Chile Trench range from -4,000 to -4,200 (827 recorded samples) versus the range of -4,500 to -4,700 m for the Peruvian segment (1,410 samples). The Peruvian segment of the trench is deeper and its geomorphology steeper with abrupt slopes compared to the Chilean segment. A comparison of the data distribution for both segments gives the following results. The Peruvian segment has the majority of data (23%) reaching 1,410 (-4,500 m to -4,700 m). This peak shows a steep pattern in data distribution, while other data in the neighbouring diapason are significantly lower: 559 (-4,700 m to -5,000 m) and 807 (-4,200 m to -4,400 m). The Chilean segment has more unified data distribution for depths of -6,000 m to -7,000 m. This paper presents GMT workflow for the cartographic automatic modelling and mapping deep-sea trench geomorphology
Machine learning techniques for calorimetry
No full textThe Compact Muon Solenoid (CMS) is one of the general purpose detectors at the CERN Large Hadron Collider (LHC), where the products of proton-proton collisions at the center of mass energy up to 13.6 TeV are reconstructed. The electromagnetic calorimeter (ECAL) is one of the crucial components of the CMS since it reconstructs the energy and position of electrons and photons. Even though several Machine Learning (ML) algorithms have been already used for calorimetry, with the constant advancement of the field, more and more sophisticated techniques become available, which can be beneficial for object reconstruction with calorimeters. In this paper, we present two novel ML algorithms for object reconstruction with the ECAL that are based on graph neural networks (GNNs). The new approaches show significant improvement compared to the current algorithms used in CMS
Current Development of Tourism and Recreation on Baltic Sea Coasts: New Directions and Perspectives
No full textResearch work analyzes current situation and development of tourism in the region of Baltic Sea. Specific case study of this paper is Pärnu Bay, Estonia. This region is known for unique environmental settings: mild maritime climate, broad beaches, coniferous pine forests on the coastal zone and high esthetic value of the surrounding landscapes. However, after the end of USSR, Estonia survived a difficult period of re-structuring of economic and social system. This affected touristic cluster, rapidly developing in new directions. Soviet touristic areas became abandoned and re-constructed, new hotels are being actively created, intensive privatization of recreation houses is actively ongoing. Main problem in the touristic cluster in Estonia consists in its specific location on the Baltic Sea with cold climate in summer period. It causes low popularity among tourists, comparing to Mediterranean. Another problem consists in ongoing development of the country, reflected in low investments into tourism, comparing to other European countries. Therefore, the main perspective for the tourism development in Estonia includes active redirection towards eco-style sustainable tourism: camping, biking, sea side recreation, construction of summer cottages for vacations, organized tours to Natural Parks. This paper, supported by fieldwork, has analytical character reviewing current Estonian tourism dynamics. Sociopolitical effects on current tourism directions are discussed, while modern touristic system in Estonia compared to Soviet. The overview of the recreation resort places was performed in Häädemeeste municipality, Pärnu district, and resulted in series of thematic author photos. The research was performed at the University of Tartu
‘Nuclear weapons are our best friends’: A Discourse-Historical Analysis of the Cold War Era Rhetoric of Nuclear Militarism
No full textThis contribution focuses on a case study involving two prominent conservative activists – Phyllis Schlafly and Chester Ward – who authored an extended election brochure, The Gravediggers (1964), in a bid to boost the 1964 election campaign of the Republican candidate Barry Goldwater. The main author of The Gravediggers, Schlafly was concerned with what she saw as the erosion of American nuclear capacity and the weakening of the nation’s security in the Cold War era of the 1960s. As a religious, anti-Communist and (later) anti-feminist activist, Schlafly was adamant that the Democratic Kennedy-Johnson Administration’s defence policy
and its disarmament mindset were making America vulnerable to nuclear attack and complete annihilation by the Soviet Union. She sought to protect America’s nuclear superiority by producing campaign literature that exhorted her conservative readers to vote for Barry Goldwater, who stood for the policy of nuclear superiority and strong strategic defence.
Schlafly’s powerful rhetorical style has been described as “militaristic” (Calahane 2022) and “bellicose” (Critchlow 2015). Using the Discourse-Historical Approach (Wodak 2015), the study combines linguistic analyses with historical and sociological methodologies in a bid to shed light on The Gravediggers as a pro-nuclear text representative of a sample of larger conservative defence literature of the period under investigation. The main focus of the investigation is on the role of argumentation strategies realised mainly as topoi of danger/threat, history, evil and (impeded access to) the people’s democratic participation, that Schlafly and Ward made use of to argue against the policy of nuclear disarmament and in favour of maintaining a confrontational attitude towards the USSR
Climatic influence on the lake drainage processes and vegetation dynamics in arid ecosystems of southern Africa
No full textDroughts and climate fluctuations can lead to seasonal drying in Etosha Lake, located in northern Namibia. Repetitive rises in temperature and lack of precipitation affect the hydrology and ecosystem health of using landscape of the Etosha Pan. Land cover dynamics of this salt ephemeral basin, located in Namibia, are subject to the climate and meteorological setting. To date, the spatiotemporal monitoring of this specific region of southern Afri-ca, including the driving factors of salinity and the water cycle, and the drainage dynamics of the lake, remains unclear. The remote location of this area and the extreme desert climate make fieldwork in this region a challenge. Using a series of six multi-spectral Landsat 8-9 OLI/TIRS satellite images and cartographic products (CORINE and GEBCO for thematic and topographic mapping), we identify seasonal variations in the surface of the Etosha National Park affecting drainage events in the lake basin. Extreme heat periods (summer-early autumn) resulted in the drying of the basin, which was covered by the crust of salt and minerals, while wet periods in winter and early spring favour the growth of vegetation. Technically, this paper presents the use of the Machine Learning (ML) methods of GRASS GIS by libraries of Python Scikit-Learn for image classification by an ensemble learning approach with a Random Forest (RF) classifier. Land cover types were identified using ML modules of GRASS GIS and scripting techniques. The methodology of scripts is presented in the GitHub repository of the author. The results demonstrated seasonal landscape dynamics in Etosha Pan. The ML method of image classification proved to be an effective tool for monitoring changes in the landscapes of northern Namibia, Africa
“How am I to answer this in English?”. Pragmatic fluency in a nineteenth-century English-language teaching text
No full textAbstract – In this contribution, I discuss the pragmatic dimension of a curious little volume entitled Friends at Home and Abroad; or, Social Chat: A connected tale in a series of imaginary conversations, illustrative of English phraseology and idioms to facilitate the acquirement of English as a living tongue (1890 [1876]), published by Theophilus C. Cann, a prolific and popular author of English language teaching materials. So far, only a handful of studies have examined the history of English language learning and teaching in Italy and my investigation aims to further our knowledge of how English was taught and learned in Italy in the second half of the nineteenth century. More specifically, in my analysis of Social Chat I am interested in identifying specific learning goals that were associated with the acquisition of pragmatic fluency, the uses of the text in the teaching and learning of English, and the type of learners who would have been Social Chat’s intended primary audience
