Abstract (sommario):

This research leverages insights from both social cognitive theory (SCT) and stimulus-organism-response theory (S-O-R) to investigate how digital entrepreneurship education (DEE) influences undergraduate students’ digital entrepreneurial alertness (DEA), motivation (DEM), and intentions (DEI). The main objective of the study was to examine whether individual levels of DEA and DEM independently and sequentially mediate the relationship between DEE and DEI. To collect the data, convenience sampling was utilized, involving 221 students from a single public university in Saudi Arabia, and a theoretical model was examined utilizing structural equation modelling (SEM) techniques in SPSS AMOS (Version 27). The results found that DEE had a significant positive impact on students’ DEIs, DEA had a significant positive impact on students’ DEI, and DEM had a significant positive impact on students’ DEI. Moreover, the results of the serial mediation analysis indicated that DEA and DEM served as independent and sequential mediators in the relationship between DEE and DEI. These findings provide further insight into the association between DEE and DEI, offering valuable implications for both entrepreneurship education curriculum developers and government policymakers. This study adds substantial contributions to the existing literature on entrepreneurship education and DEI.

Abstract (sommario):

This paper presents a new numerical method for multiscale modeling of composite materials. The new numerical model, called DECM, consists of a DEM (Discrete Element Method) approach of the Cell Method (CM) and combines the main features of both the DEM and the CM. In particular, it offers the same degree of detail as the CM, on the microscale, and manages the discrete elements individually such as the DEM—allowing finite displacements and rotations—on the macroscale. Moreover, the DECM is able to activate crack propagation until complete detachment and automatically recognizes new contacts. Unlike other DEM approaches for modeling failure mechanisms in continuous media, the DECM does not require prior knowledge of the failure position. Furthermore, the DECM solves the problems in the space domain directly. Therefore, it does not require any dynamic relaxation techniques to obtain the static solution. For the sake of example, the paper shows the results offered by the DECM for axial and shear loading of a composite two-dimensional domain with periodic round inclusions. The paper also offers some insights into how the inclusions modify the stress field in composite continua.

Abstract (sommario):

Since the land surface has been changing naturally or manually, DEMs have to be updated continually to satisfy applications using the latest DEM at present. However, the cost of wide-area DEM production is too high. DEMs, which cover the same area but have different quality, grid sizes, generation time or production methods, are called as multi-source DEMs. It provides a solution to fuse multi-source DEMs for low cost DEM updating. The coverage of DEM has to be classified according to slope and visibility in advance, because the precisions of DEM grid points in different areas with different slopes and visibilities are not the same. Next, difference DEM (dDEM) is computed by subtracting two DEMs. It is assumed that dDEM, which only contains random error, obeys normal distribution. Therefore, student test is implemented for blunder detection and three kinds of rejected grid points are generated. First kind of rejected grid points is blunder points and has to be eliminated. Another one is the ones in change areas, where the latest data are regarded as their fusion result. Moreover, the DEM grid points of type I error are correct data and have to be reserved for fusion. The experiment result shows that using DEMs with terrain classification can obtain better blunder detection result. A proper setting of significant levels (α) can detect real blunders without creating too many type I errors. Weighting averaging is chosen as DEM fusion algorithm. The priori precisions estimated by our national DEM production guideline are applied to define weights. Fisher’s test is implemented to prove that the priori precisions correspond to the RMSEs of blunder detection result.

Abstract (sommario):

The main cause of the protracted droughts and floods that occur in different regions of the country is poor water resource management, which also impedes national development. The only solution is to build a canal from the neighboring dam or rivers to the drought- affected communities. GIS and remote sensing can be used to conduct multidisciplinary research on agricultural and horological elements, which is necessary for the enormous task of building canals. With consideration for geomorphology, soil, land use and land cover, slope, and DEM (digital elevation model), this project outlines the design of an appropriate canal building route from Jayakwadi Dam to Dudana Dam. Rivers can also be connected by canals. The SOI data provides digital topography and drainage pattern information, whereas the LISS III picture provides land use/cover pattern information. Using the ASTER DEM picture, 1 meter contours were created. The canal was aligned horizontally and vertically using the Digital Elevation Model (DEM), which was obtained by interpolating contour lines. A number of possible options have been considered based on the GIS analysis. When determining the canal alignment, the study considered a number of elements, including slope, drainage, ground contours, and DEM. First, a proposed 84-kilometer canal between the Dudana and Jayakwadi dams has been put forth. The interlinking canal would be around 102 km long up to the Dudana Dam. Gravity is this canal's main purpose. In the current study cutting and filling reach zones have also been identified. Key Words: Canal system, Remote Sensing, GIS, DEM

ZusammenfassungAnfang der 2000er Jahre bildeten sich einige Berufsgewerkschaften, die das alte System der Tarifeinheit lockerten, bis das Bundesarbeitsgericht schließlich 2010 die Tarifpluralität grundsätzlich zuließ. Mit dem Tarifeinheitsgesetz von 2015 sollte die Macht kleiner Berufsgewerkschaften wieder eingegrenzt werden. Die Regeln im Tarifeinheitsgesetz sind jedoch zu unbestimmt um zu verhindern, dass es zu Konflikten der Gewerkschaften innerhalb eines Unternehmens kommt. Die Bahn bietet hier ein gutes Beispiel.

Abstract (sommario):

The 1772 cemetery reform of Catherine the Great, Empress of Russia, resulted in great changes in the cemetery culture of Russia’s Baltic provinces. The ban on burials in churches and the vicinity of churches resulted in the rapid development of cemetery parks outside of settlements. The strong political relations of Estonia’s manor owners with the Russian central government resulted in the nobles being given the privilege to establish burial plots in the churchyards, but in Livonia, this was strictly prohibited. Simultaneously with the parish cemeteries, the owners of private manors established family cemeteries on their manors. The new cemeteries were not only places to bury the dead, but, inspired by contemporary poets, they were seen as family altars, which were visited regularly and which was accessed by path that was attuned to contemplation.The cemetery is complex, which includes a garden, chapel and allée, and if possible, a body of water. Noble trees were planted along the path leading to the cemetery. Oaks were preferred, which due their mighty shape were considered to be the symbol of family and nobility. Influenced by the poetry of the Enlightenment, evergreens – silver firs, thuja trees, and spruces – were called “sad trees”. The French poet Jacques Delille, whose works were popular among the Baltic Germans, sees women as mourners. And many family cemeteries were established at the initiative of women. Examples of Ancient Greek architecture, in the form of temples with porticos or antas, or the small-scale copies of the Pantheon from Ancient Rome, dominated in cemetery architecture. The chapel was comprised of underground burial chambers and above-ground memorials. A so-called memorial altar was located in the end wall of the chapel, which have survived until the present day in a few places. The Barclay de Tolly monument is the most majestic in Estonia.Already in the 1830s, the family chapels became memorials and burials no longer took place there. However, chapels continued to be built until in Estonia until the early 20th century.

Abstract (sommario):

Airborne aircrafts are dependent on the Global Navigation Satellite System (GNSS), which is susceptible to interference due to the satellite base-station and cooperative communication. Synthetic aperture radar altimeter (SARAL) provides the ability to measure the topographic terrain for matching with Digital Elevation Model (DEM) to achieve positioning without relying on GNSS. However, due to the near-vertical coupling in the delay-Doppler map (DDM), the similarity of DDMs of adjacent apertures is high, and the probability of successful matching is low. To this end, a novel neural network of terrain matching and aircraft positioning is proposed based on the airborne SARAL imagery. The model-driven terrain matching and aircraft positioning network (TMP-Net) is capable of realizing aircraft positioning by utilizing the real-time DDMs to match with the DEM-based DDM references, which are generated by a point-by-point coupling mechanism between the airborne routine and ground terrain DEM. Specifically, the training dataset is established by a numerical simulation method based on a semi-analytical model. Therefore, DEM-based DDM references can be generated by forward deduction when only regional DEM can be obtained. In addition to the model-based DDM generation, feature extraction, and similarity measurement, an aircraft positioning module is added. Three different positioning methods are designed to achieve the aircraft positioning, where three-point weighting exhibits the best performance in terms of positioning accuracy. Due to the fact that both the weighted triplet loss and softmax loss are employed in a cooperative manner, the matching accuracy can be improved and the positioning error can be reduced. Finally, both simulated and measured airborne datasets are used to validate the effectiveness of the proposed algorithm. Quantitative and qualitative evaluations show the superiority.
