The number of large coal power plants, characterized by pithead is increasing rapidly in major mining countries around the world. Overburden movement caused and greenhouse gas emissions thermal generation are intertwined, have become important challenges for mine ecological environment protection at present future. In order to provide more options green a base northwest China was taken as resea...

Self-assembly provides an information-economical route to the fabrication of objects at virtually all scales. However, there is no known algorithm to program self-assembly in macro-scale, solid, complex 3D objects. Here such an algorithm is described, which is inspired by the molecular assembly of DNA, and based on bricks designed by tetrahedral meshing of arbitrary objects. Assembly rules are ...

The application of steel fiber reinforced polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing squ...

This paper presents the study of a two-hundred-year-old, demolded solid clay brick using rebound hammer test for estimation compressive strength. During test, location and face type influence on values are monitored recorded. In addition, calculation average value has been modified to encounter types. Furthermore, estimated strength is compared with normalized mean check accuracy if it within c...

The paper presents a case study where the energy demand for a listed building constructed in 1900 is reduced. Many older buildings are listed and have restrictions that include the entire building or that include only its exterior. For the building presented, only its exterior facade is listed. The paper demonstrates measures for the improvement of the thermal insulation of the building with so...

LEGOsheets was created. LEGOsheets is an educational environment implemented in Agentsheets, a grid-based tool for creating visual programming languages [5]. Programming can serve as a vehicle to create learning opportunities in the constructionist sense [3]. The LEGO1 Programmable Brick gives children the ability to create physical artifacts, such as vehicles and robots, and program them with ...

In this study, five one-way brick slab specimens were manufactured to investigate the behavior of slabs composed various types bricks (solid bricks, perforated and cellular concrete blocks (thermostone). The span ranges from 600 800 mm, while camber 0 30 mm. Previously, blocks, solid clay employed as building materials. These samples tested by being subjected flexural three-point loading. resul...

In this paper, we discuss the applicat[ons ant! implications of the Programmable Brick-s-s tiny, portable computer embecfded ~nside a LE~Q'J brick, capable of interacting with the phys!cal world in a large variety of ways. We describe how Programmable Bricks make possible a wide range of new design activities for children, and we discuss experiences in using Programmable Bricks in three types o...
