Bike-sharing is adopted as a valid alternative to traditional public transports since they are eco-friendly, prevent traffic congestions, reduce the probability of social contacts which happens on most means. However, some problems may occur such irregular distribution bikes stations/racks/areas, and difficulty knowing in advance rack status with certain degree confidence, whether there will be...

In recent trends the development of structural steel using cold formed section plays a vital role in main frame construction portal frames. These frames find its use economic industrial, agricultural and residential buildings due to lightweight robustness. With major claims comparison with hot rolled profiles, possesses low cost, highly versatile standard design procedures. Among various design...

In this research, the influence of global slenderness and sliding pallets factor on seismic design steel storage racks are assessed. Variations in span length, height levels, live load, percentage load considered mass studied for different levels zone soil type. The models were designed according to Chilean Code NCh2369. Subsequently, a sensitivity analysis was developed analyze each parameter ...

In this paper, a question due to Heckenberger, Shareshian and Welker on racks in Heckenberger et al. (Trans Am Math Soc, 372:1407–1427, 2019) is positively answered. A rack set together with self-distributive bijective binary operation. We show that the lattice of subracks every finite complemented. Moreover, we characterize modular lattices terms complements subracks. Also, introduce certain c...

Given a finite bijective non-degenerate set-theoretic solution (X,r) of the Yang–Baxter equation we characterize when its structure monoid M(X,r) is Malcev nilpotent. Applying this characterization to solutions coming from racks, rediscover some results obtained recently by Lebed and Mortier, Vendramin on description abelian racks quandles. We also investigate multipermutation (not necessarily ...

Liveability is a complex, multifaceted concept with various definitions, but an agreed core set of features (e.g., safety, walkability). Typically, liveability measured at the macro-level (city or regional-level), and has been used in advocacy by local populations. However, micro-level (street-level) measurements could also/alternatively be to identify modifiable environmental impacting health ...
