The stabilization of landslide is usually very costly, which is why optimal slope reinforcement should be based on exact geological investigations. The described case of a small landslide on the road in the Carpathians presents the process of documenting, stability analysis and design solutions for slope reinforcement. Depth of slip surface was the most important information for slope reinforcement first-design. Collapsed slope was subjected to re-analysis of stability, taking into account additional data already obtained during slope reinforcement. Stability modeling results indicate a different range and depth of the slip surface than those use for design, which had a major impact on the costs of stabilization.

6G of mobile networks plays a crucial role in improving the capacity and enhancing the quality of services of Vehicle-to-Everything (V2X) based networks evolving in an intelligent environment. VANET is a promising project in the intelligent transportation field using V2X communications. The emergence of several 5G and 6G technologies has raised several challenges for scientists and researchers to allow vehicles and road users to enjoy several services while ensuring their safety on the road. Among these technologies, the unmanned aerial vehicle (UAV), which can perform different tasks for road users and vehicle drivers such as data caching, packet relaying and processing. In this article, we present a new approach based on 6G Unmanned Aerial Vehicles (UAV) technology on a vehicular cloud architecture while exploiting the exchange support of information-centric networking (ICN) for the improvement of network capacity.

<p><span>The modeling of a car is essentially done by taking into consideration the driving terrain, traffic conditions, driver’s behavior and various other factors which may directly or indirectly affect the vehicle’s performance. A vehicle is modeled for given specifications and constraints like maximum speed, maximum acceleration, and braking time, appropriate suspension for the gradient of the road and fuel consumption. Henceforth, a profound study and analysis of different drive cycles are essential. A time dependent drive cycle is a condensed form of data that helps us to determine the time taken to conduct the driving test on the road. This article highlights the development of a real driving cycle in the area of Tamilnadu, India. On-road vehicle’s speeds versus time data were obtained along the selected route. The data obtained were analyzed first and then a new driving cycle was developed.</span></p>

Is “the new modernism” in domestic architecture—sometimes called “internationalism”—a useful step on the road toward sustainable buildings? Mindless recreations of traditional forms from other times and places are no better, as many writers have noted, but any building's natural and cultural context must play a fundamental role in the design, materials selection, and even the detailing, if sustainability is to be more readily achieved. The role of place-based planning has been well researched and reported (Clarke 2006; Mant 1998, 2000; NSW Department of Urban Affairs and Planning 2001). Less well understood is the role of “localness” in building design. This informs the overall form of buildings, and their detailing, as well as their technical functionality. A local understanding stems from a sense of materials, climate, and indigenous or local culture, and informs the design process at every level. In this article, the position of internationalist domestic architecture (espoused in glossy architecture publications) is criticised, drawing also on previous research (a case study of the outcomes of a place-based planning instrument, by the author, and a joint paper on locality-based design written jointly with Trevor King). The internationalist design approach is shown not to provide culturally appropriate or technically sustainable buildings.

Slope uncertainty predominantly originates from the imperfect analysis model and the inaccuracy and imprecision of the observations. The strength reduction method (SRM) is widely used to attain the safety factor (SF) of the slopes, which is similar to interpretation of the limit state (LS). In this paper, the spectral element method (SEM), using an elasto-plastic Mohr–Coulomb failure criterion, is employed to project the plausible LS of the soil slopes. An iterative SRM search method is proposed to evaluate the SF of the slopes regardless of the LS interpretation. The proposed SRM paradigm encompasses the design trigger to trace the uncertain parameters in decision-making. This method is applied to three numerical examples: (1) a homogeneous dry slope, (2) a dry slope with a weak layer, and (3) a partially-wet slope with a weak layer. It is shown that for the case study examples, the proposed SRM reasonably converges to the required precision. Results further are compared and contrasted with some of the conventional and standard techniques in slope stability. This hybrid procedure paves the road for fast and safe stability analysis of man-made and natural slopes.

This study demonstrates through a case study that detailed analyses, even after the construction of a project, are feasible using current technologies and available data. A case study of highway 25 is used to illustrate the method and verify the levels of air contaminants from additionally induced traffic during and after the construction of highway. Natural traffic growth was removed from the effect of observed gas emissions by comparing observed levels on other further locations in the same metropolitan area. This study estimates air pollution from the additional traffic during and after the construction of A-25 extension project. NO2 levels were spatially interpolated during peak and off-peak hour traffic and traffic density simulated on the road network for four scenarios. Comparing the four scenarios, it was found that levels of NO2 concentrations were reduced at neighbor areas due to less traffic during the construction period. Levels of NO2 after the construction were higher than those in 2008. The simulated traffic density for four scenarios revealed that traffic density was significantly increased on both arterial and access roads within the close vicinity of the extension project during and after its construction.
