Intelligent tower crane has large structure deadweight. The service life of the whole machine is dependent on the life of the structure. As a result, the metal structure should be designed by using correct and reasonable methods to obtain excellent fatigue properties. And it can guide the design, manufacturing, use and maintenance process for crane. And it has great significance to prevent the ...

Pykrete is a material used for temporary structures in cold environments. In the last decade, this has generally been shell that were constructed using inflatable fabric formwork and ropes. Recently, research carried out to use pykrete made of linear elements some low heights have able be built. A tower-like structure was built 2019 International Ice Snow Innovation Design Construction competit...

A heuristic method for optimizing a solar power tower system is proposed, in which both heliostat field (heliostat locations and number) and the tower (tower height and receiver size) are simultaneously considered. Maximizing the thermal energy collected per unit cost leads to a difficult optimization problem due to its characteristics: it has a nonconvex black-box objective function with compu...

In the design of DC system, more than one MVU tower may be used between pole-to-neutral voltages. This is especially common for UHVDC systems. The insulation design of these MVU’s need to be verified by dielectric type tests as specified by international standards. However, the application of several MVU’s in series makes the test set-up complicated. One straightforward solution is to install a...

Application of structural optimization to transmission tower design is facilitated since major costs, e.g. material, transportation, erection and maintenance, are directly proportional to structural mass and economies of scale exist. In this paper, Structural Topology and Shape Annealing (STSA), a structural topology optimization method that combines structural grammars with simulated annealing...

The purpose of this work was to develop a continuous fermentation system operating with a tower reactor using some flocculent yeast strains isolated from an industrial process. The strain was an used in the trial of the proposed system, composed of two serial glass tower reactor. The effects of the following variables were studied on the yield and productivity of the system: total reducing suga...
