Tourist maps are designed to direct tourists to tourist attractions in unfamiliar areas. A well-designed tourist map can provide tourists with sufficient and intuitive information about places of interest. Thus, providing up-to-date information on places of interest and selecting their representative icons are fundamental and important in automatic generation of tourist maps. In this article, approaches for determining places of interest and for determining their representative icons are introduced. In contrast to general digital tourist maps that use text, simple shapes, or three-dimensional models, we use photos that offer abundant visual features of places of interest as icons in tourist maps. The photos are automatically extracted from a repository of photos downloaded from photo-sharing communities. Tourist attractions and their corresponding image icons are determined by means of photo voting and photo quality assessment. Qualitative analyses, including a user study and experiments in several areas with numerous tourist attractions, indicated that the proposed method can generate visually pleasant and elaborate tourist maps. In addition, the analyses indicated that the map produced by our method is better than maps generated by related methods and is comparable to hand-designed tourist maps.

SummaryComputational elucidation of membrane protein (MP) structures is challenging partially due to lack of sufficient solved structures for homology modeling. Here we describe a high-throughput deep transfer learning method that first predicts MP contacts by learning from non-membrane proteins (non-MPs) and then predicting three-dimensional structure models using the predicted contacts as distance restraints. Tested on 510 non-redundant MPs, our method has contact prediction accuracy at least 0.18 better than existing methods, predicts correct folds for 218 MPs (TMscore>0.6), and generates three-dimensional models with RMSD less than 4Å and 5Å for 57 and 108 MPs, respectively. A rigorous blind test in the continuous automated model evaluation (CAMEO) project shows that our method predicted high-resolution three-dimensional models for two recent test MPs of 210 residues with RMSD ∼2Å. We estimated that our method could predict correct folds for 1,345–1,871 reviewed human multi-pass MPs including a few hundred new folds, which shall facilitate the discovery of drugs targeting at membrane proteins.

Puncak Menara Api in Gunung Saribu Village, Munte Sub-District, Karo Regency, is a buffer zone of the protected forest area in Karo Regency. In 2020, all the local communities through village funds are trying to pioneer the development of Puncak Menara Api as a new tourist attraction. In relation to such an effort, the community service team of Universitas Sumatera Utara assisted the people in Gunung Saribu Village in creating the concept of developing Puncak Menara Api as a nature-based and education-based tourist attraction in Karo Regency. The assistance includes but not limited to improving the capacity of tourism management for rural communities, mapping the tourist sites, marketing the tourist sites, and so forth. For the many development activities items that must be done, the team selected mapping tourist sites as the only activity to be carried out in 2020. This study was conducted using a qualitative method. The data were collected using focus group discussion, observation, and interview techniques. The data were analyzed using visual analysis, including visualizing the point object attributes, visualizing point object distribution, and visualizing spatial groupings. The results of the study are: (i) the visualization on the point object attributes finds four main components related to tourism: Attractions, Accessibility, Amenities, and Ancillary Services; (ii) the visualization on the point object distribution results in predicting the initial picture of the arrangement of tourist attractions in Puncak Menara Api; and (iii) the visualization on the spatial groupings results in designing the tourist location in a three-dimensional design.

The objective definition of footprint margins poses a central problem in ichnology. The transition from the footprint to the surrounding sediment is often continuous, and the footprint wall complex, requiring interpolation, approximation, and a priori assumptions about trackmaker anatomy to arrive at feasible interpretations of footprint shapes. The degree of subjectivity of such interpretations is substantial, and outlines produced by separate researchers can differ greatly. As a consequence, statistical shape analysis, regardless if based on linear and angular measurements or on the shape as a whole, are neither fully repeatable nor objective. Here I present an algorithm implemented in the programming environment R that is able to generate continuous footprint outlines based on three-dimensional models—fully automatically, objectively, and repeatable. The approach, which is based on contour lines extracted from the model, traces the outline at the point where the slope of the track wall is steepest. An option for automatic landmark placement is implemented for tridactyl footprints. A case study was carried out on 13 footprints of a single trackway of a theropod trackmaker from the Lower Cretaceous of Münchehagen, Germany. Analysis of the landmark coordinates returned by the script did reproduce statistical results published in an earlier study that was based on human-made interpretative drawings, demonstrating the applicability of the present method for the objective and quantitative shape analysis of tracks. Although faint anatomical details are not always recorded and features not related to the foot anatomy may be included, the generated outlines tend to correspond with human-made interpretative drawings regarding the overall shape. While not suited as a full replacement of interpretative drawings, these generated outlines may be used as an objective basis for such interpretations.

Indonesia is a country that is well known for the charm of its tourist attractions. The area in Indonesia having the most striking tourist objects is Bali. Bali has been an area known as the island of a thousand temples; the thickness of traditional culture combined with modern culture is its main attraction. One of the tourist objects offering aesthetic value in Bali is Tirta Empul, a place that is believed to be a place for bathing (melukad) with several springs that can make a person’s condition better than earlier. The purpose of this research is two-fold: to examine the management of the Tirta Empul tourist attraction in the Manukaya Let Tampaksiring Customary Village and to reveal the obstacles experienced by the customary villages in maintaining and managing these tourist objects. This study uses a normative legal research design. The results show that the village government made an agreement with the Tourism Office with the aim of developing Tirta Empul tourism attraction and preserving local culture. Some problems or deficiencies in smoothing the goal of cooperation include the lack of intention of the village community in managing the Tirta Empul tourist attraction, equipment and facilities that support cleaning of their respective tourist attractions and the number of tourists who do not pay attention to cleanliness by littering carelessly despite the many trash cans provided, thus creating heas.

Abstract The content of the research is divided into four points. The first part considers the need of 3D models creation - good practices applied in different countries related to Internet services for urban development and planning, preservation of cultural heritage, as well as scientific research. The second part focuses on the nature of 3D modeling, addressing theoretical issues concerning conceptual modeling, classification of three-dimensional models, geometry and topology. Different data formats are described. The third part focuses on an overview of the different 3D data sources and 3D modeling methods. The fourth part includes the description of a specific software for creating, editing and presenting 3D models - City Engine. The functionality, the specific possibilities for additional analysis and extraction of attribute information from the created models are described, as well as the programming language used in creating three-dimensional models in the software environment. In the fourth part, practical tasks are performed, which aim to make a comparison between the actual state of construction with the set project values in the general development plan for Sofia Municipality. 3D models of buildings in a neighbourhood in the Lozenets region were created, after which an additional analysis of the current state of construction was performed. The possibilities of the software for automatic generation of a street network are considered, as well as the functionality related to the modeling of facades.

The relation between authoritarianism and social dominance orientation was analyzed, with authoritarianism measured using a three-dimensional scale. The implicit multidimensional structure (authoritarian submission, conventionalism, authoritarian aggression) of Altemeyer’s (1981, 1988) conceptualization of authoritarianism is inconsistent with its one-dimensional methodological operationalization. The dimensionality of authoritarianism was investigated using confirmatory factor analysis in a sample of 713 university students. As hypothesized, the three-factor model fit the data significantly better than the one-factor model. Regression analyses revealed that only authoritarian aggression was related to social dominance orientation. That is, only intolerance of deviance was related to high social dominance, whereas submissiveness was not.

Abstract An integrated model is under development which will be able to predict the interior noise due to the vibrations of a rolling tire structurally transmitted to the hub of a vehicle. Here, the tire belt model used as part of this prediction method is first briefly presented and discussed, and it is then compared to other models available in the literature. This component will be linked to the tread blocks through normal and tangential forces and to the sidewalls through impedance boundary conditions. The tire belt is modeled as an orthotropic cylindrical ring of negligible thickness with rotational effects, internal pressure, and prestresses included. The associated equations of motion are derived by a variational approach and are investigated for both unforced and forced motions. The model supports extensional and bending waves, which are believed to be the important features to correctly predict the hub forces in the midfrequency (50–500 Hz) range of interest. The predicted waves and forced responses of a benchmark structure are compared to the predictions of several alternative analytical models: two three dimensional models that can support multiple isotropic layers, one of these models include curvature and the other one is flat; a one-dimensional beam model which does not consider axial variations; and several shell models. Finally, the effects of internal pressure, prestress, curvature, and tire rotation on free waves are discussed.

Meanwhile, owing to the large pore size (11.4 Å) and suitable intermolecular distance of aligned TPE (7.2 Å) in JUC-555, the obtained material demonstrates an excellent performance in the molecular recognition of hazardous chemicals, e.g., nitroaromatic explosives, PAHs, and even thiophene compounds, via a fluorescent quenching mechanism. The quenching constant (<i>K</i><sub>SV</sub>) is two orders of magnitude better than those of other fluorescence-based porous materials reported to date. This research thus opens 3D functionalized COFs as a promising identification tool for environmentally hazardous substances.</p>
