Abstract:

Paper artifacts are important carriers of history and culture. As they age and are affected by environmental factors, their protection and restoration become increasingly important. This paper discusses the restoration techniques for paper artifacts, including cleaning, acid removal, strengthening, and surface protection. It also considers the application of digital technologies in artifact restoration. Digital scanning, virtual restoration, and digital display provide new solutions for artifact restoration, effectively protecting artifacts from further damage, enhancing accessibility, and pro

Abstract:

In this paper I present a new dimension for philosophical and scientific analysis of artifacts as anthropogenic abiotic objects along the lines of the distinction between real and virtual. This distinction purports to replace the classical opposition material–ideal as a better way of defining what an artifact is and as one more compatible with the scientific description and explanation of artefacts. The virtual relativity of the virtual artifacts is their relatedness to local language forms as an adequate coordinate system. The real relativity of artifacts is their relatedness to local and glo

Abstract:

With the rapid development of artificial intelligence, automated artifact recognition technology has gradually replaced the traditional manual quality evaluation method. The existing samples of CT images containing artifacts are small, and the relationships between the images are of great significance. In this study, firstly, a method for CT image artifact recognition was developed by transforming the problem into a node classification framework. Secondly, the characteristics of this complex network and the features of the CT image texture were extracted. Finally, the combination of the comple

Abstract:

In this study, a novel algorithm named the Edge-enhanced Generative Adversarial Network (EGAN) is proposed to address the issues of noise corruption and edge fuzziness in the super-resolution of remote sensing images. To build upon the baseline model called Deep Blind Super-Resolution GAN (DBSR-GAN), an edge enhancement module is introduced to enhance the edge information of the images. To enlarge the receptive field of the algorithm, the Mask branch within the edge enhancement structure is further optimized. Moreover, the loss of image consistency is introduced to guide edge reconstruction, a

Because receiver wavefields reconstructed from observed data are not as stable as synthetic source wavefields, the source-propagation vector and the reflector normal have often been used to calculate angle-domain common-image gathers (ADCIGs) from reverse time migration.

Video Compression Artifact Reduction aims to reduce the artifacts caused by video compression algorithms and improve the quality of compressed video frames.

Abstract:

Over recent years, there has been an increase in popularity of the acquisition of dermoscopic skin lesion images using mobile devices, more specifically using the smartphone camera. The demand for self-care and telemedicine solutions requires suitable methods to guide and evaluate the acquired images’ quality in order to improve the monitoring of skin lesions. In this work, a system for automated focus assessment of dermoscopic images was developed using a feature-based machine learning approach. The system was designed to guide the user throughout the acquisition process by means of a preview

Abstract:

In a small coastal vacation community heavily dependent upon foreign workers, in-depth interviews with employers, participant observations, and an analysis of social artifacts evidence patterns of neo-assimilation, in the form of fused cuisine on menus, altered attitudes towards native-born workers among employers, and in a small number of cases, intermarriage. Findings also illustrate employer engagement with the culture of their workers and a sophisticated understanding of the global dynamics of international migration and work.

From May 9–14, 2008, the Salzburg Global Seminar convened its 453rd session—and its annual arts and culture session—on “Achieving the Freer Circulation of Cultural Artifacts” at Schloss Leopoldskron in Salzburg. Sixty two participants from twenty-nine countries gathered for the five-day session, aimed at building consensus among cultural authorities and museum representatives from around the world on ways to overcome legal, political, and practical obstacles to the circulation of cultural objects. Participants worked together to identify and assess new and better ways to promote the sharing of

Abstract:

Ice patches are permanent snow and ice fields that survive through the summer months but are not massive enough to become glaciers. Prehistorically, people used ice patches for hunting, and organic hunting-related artifacts have been recovered from them. As a result of global warming, the ice patches are melting and exposing artifacts and other material that were preserved under the ice for millennia. Once exposed, the organic artifacts deteriorate. Recovery of these artifacts before they are lost is critical to understanding the paleoecology of and the prehistoric people who used the Teton hi

Abstract. Advances in trace gas analysis allow localised, non-atmospheric features to be resolved in ice cores, superimposed on the coherent atmospheric signal. These high-frequency signals could not have survived the low-pass filter effect that gas diffusion in the firn exerts on the atmospheric history and therefore do not result from changes in the atmospheric composition at the ice sheet surface. Using continuous methane (CH4) records obtained from five polar ice cores, we characterise these non-atmospheric signals and explore their origin. Isolated samples, enriched in CH4 in the Tunu13 (

Anxieties associated with global conflict surround youth and ideological narratives mediating these conflicts can be seen in the popular media youth consume. This investigation uses contemporary cultural-theoretical conceptualizations of ideology to analyze several important popular screen-based cultural artifacts created for youth consumption to determine how young audiences are invited into the ideoscapes and discourses of global politics in the age of the “war on terror.” The analysis shows that these youth-oriented media artifacts script fundamental understandings of conflict and provide s

AbstractThe International Satellite Cloud Climatology Project (ISCCP) dataset and the Pathfinder Atmospheres–Extended (PATMOS-x) dataset are two commonly used multidecadal satellite cloud records. Because they are constructed from weather satellite measurements lacking long-term stability, ISCCP and PATMOS-x suffer from artifacts that inhibit their use for investigating cloud changes over recent decades. The present study describes and applies a post hoc method to empirically remove spurious variability from anomalies in total cloud fraction at each grid box. Spurious variability removed inclu

Accomplishing long-term plans to harvest and modify natural resources has been a crucial skill for the survival of our species since early Prehistory. Research on this first step of production mostly focuses on the provenience study of lithic artifacts uncovered at archaeological sites, using petrographic and geochemical analyses to correlate the artifacts with potential geological outcrops. Although fundamental for understanding key aspects of landscape use and mobility, regional raw material economy, and extraction technology, Palaeolithic raw material sources have been less intensively inve
