The main factors affecting the load-bearing capacity of new and damaged stone structures are given. One most common types damage to buildings is their cracking. According statistics, frequent reasons for formation cracks in are: uneven settlement foundations, load on structures, temperature deformations, moisture deformations. walls depends compressive strength bricks mortar, but it difficult m...

In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

Fluid film forces are generated in multirecess journal bearings by two types of lubrication mechanism: the hydrostatic lubrication in the bearing recesses and hydrodynamic lubrication in the bearing lands, when operating in rotation. The combination of both lubrication mechanism leads to hybrid journal bearings (HJB). When part of hydrostatic pressure is also dynamically modified by means of hy...

The rate at which information can be exchanged between nodes in a hybrid network is investigated. The network includes n ad hoc nodes and b base stations, where the ad hoc nodes can share information through the wired infrastructure in addition to wireless ad hoc communication. The per-node throughput scaling achievable in this hybrid network as n (and b) grows was studied in previous work for ...
