Ferrocement, Carbon, and Polypropylene Fibers for Strengthening Masonry Shear Walls.

This paper describes an experimental investigation into the feasibility of using ferrocement jacketing, polypropylene fibers, and carbon fiber reinforced polymer sheets (CFRP) to enhance the shear resistance of unreinforced brick masonry. The study involved testing 12 wall panels in diagonal compression, three of which were strengthened using each of the above-mentioned techniques. The results showed that all three strengthening techniques led to a significant improvement in the shear resistance and deformation capacity of the unreinforced walls.

Speed violation analysis of heavy vehicles on highways using spatial analysis and machine learning algorithms.

With the development of technology in the world, vehicles that reach high speeds are produced. In addition, with the increase of road width and quality, faster and more comfortable transportation can be provided. These developments also increase the speed violation rates of road vehicles.

Public transit usage and air quality index during the COVID-19 lockdown.

The people suffering from coronavirus have to lead unprecedented actions including limiting travel especially using public transportation. Therefore, lockdown measures and social distancing to decelerate the distribution of the COVID-19 has become the new norm. Nevertheless, improvement in the ambient air quality of the cities globally has appeared as a key advantage of this lockdown.

A GIS and microsimulation-based MCDA approach for evaluation of pedestrian crossings.

Pedestrian crossings are sites in which vehicles and pedestrians can crash into each other, and are very important in terms of urban traffic. Drivers and pedestrians are more likely to violate traffic regulations, and thus adversely affect traffic safety and flow, in streets that have many such crossings. Careful planning of pedestrian crossing locations provides a solution to these problems.
