Photovoltaics (PV) can make a significant contribution to achieving carbon neutrality in buildings. Geographic information systems (GIS) it easy model cities and simulate PV with high accuracy. However, the computational burden from 3D urban models remains high. In this study, complex geometry of city was represented 2D images, we propose method for performing multiple simulations short amount ...

The unequal area facility layout problem (UA-FLP) refers to the reasonable arrangement of a certain number facilities in given area. should satisfy constraints and optimize optimization objectives as far possible. In this paper, method combining improved lowest horizontal line particle swarm algorithm is proposed solve UA-FLP, which achieves multi-objective material handling cost, adjacent valu...

In communicative exchanges, sentences are uttered against a background of shared beliefs or attitudes which helps the audience to determine the content of what the speaker has said. Unfortunately, different agents may have different views of this common ground. From this standpoint, one of the most familiar phenomena is accommodation, which enables the addressee to incorporate the speaker’s pre...

BACKGROUND The number of hip fractures occurring worldwide in 1990 was estimated at 1.7 million and is predicted to rise to 6.3 million by 2050. The vast majority occur as a result of simple falls and the impact of the femoral trochanter with the floor. Previous studies have addressed the problem from the patient's side of the impact. Little research has been carried out on the other surface in...

In mine roadway support operations, floor bolting not only played a role in floor heave control, but also in reinforcing roof and its two sides. Correspondingly, bolting of roof and two sides also played a part in floor heave control. To quantify the effect of such bolting, based on roadway support in extremely weak rock, three physical models were produced and tested in laboratory. Through com...

Poplar laminated veneer lumber (LVL) orthogonal rib box floor is a new type of composed LVL beams and oriented strand board (OSB). To study the creep performance floor, four 3600 mm × 4800 specimens were designed manufactured. The tests with local damage, repeated load, different stress ratio loads conducted. increased ambient temperature humidity. Because damage increased. Repeated loading def...

How can we construct the multidimensional evaluation framework of urban vitality from perspective spatial structure? Under current intensity land development, does population density in downtown area Shanghai have potential to be improved? Can a subdistrict an appropriate scale for evaluating central Shanghai? First, based on multisource geospatial big data, comprehensive theoretical influence ...
