The strength of clay-rich sandstone decreases significantly when in contact with water due to softening effects.This scenario can pose a severe threat to the stability of water diversion tunnels during construction and operation periods.To address the issues related to water-induced softening in clay-rich sandstone zones in a water diversion tunnel
Illegal labour activity is a multi-sided notion, which shows a whole set of processes dealing with arising, realizing and terminating labour relations between worker and employer, in case infringement of law and formal standards takes place.The goal of the research is to work out trends of lowering risks of illegal labour activity in national and s
In cluster analysis, a common first step is to scale the data aiming to better partition them into clusters.Even though many different techniques have throughout many years been introduced to this end, it is probably fair to say that the workhorse in this preprocessing phase has been to divide the data by the standard deviation along each dimension
The results of research on diagonal crack width in a single Lemonade span RC beams were presented in the article.Eurocode 2 rules do not require the direct control of shear crack width.It is assumed, that reinforcement designed to carry the transverse force is also enough to limit the crack width.Experiments were led on beams grouped into four seri
