We examine how firms interact with government officials within a corruption environment. Using convictions to measure the extent of political at province level and sample Chinese listed firms, we find that located in more corrupt provinces invest building connections than less provinces. These results are robust instrumental variable approach, adjacent matching, propensity score matching altern...

Wireless indoor networks employing Radio over Fiber technique combining 60 GHz wireless networks with wired networks is a new solution to provide high definition in-home multimedia applications. About 5 Gbps is available around 60 GHz band. In 60 GHz band each antenna can cover a small space such as a single room in a building. Thus more antennas are needed to cover the whole building. This lea...

The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(2)(H(2)O)(5)]Cl(2), contains two Li(I) cations, one with a distorted trigonal-bipyramidal and the other with a distorted tetra-hedral coordination geometry. Two symmetry-related asymmetric units constitute a building block of the structure, in which both ligand carboxyl-ate O atoms are bidentate and bridge the metal ions, formi...

In the hydro/solvothermally synthesized title compound, Na(4)[Cu(2)(H(2)Ge(2)O(7))(H(2)GeO(4))(2)]·H(2)O, the framework building units include CuO(4), GeO(2)(OH)(2) and GeO(3)(OH) tetra-hedra, the latter being condensed into H(2)Ge(2)O(7) (4-) dimers. All the tetra-hedra are connected by corner-sharing into four-membered-ring (4MR) secondary building units containing two CuO(4), one GeO(2)(OH)(...

Detection and geometric reconstruction of man-made objects from high resolution, multiple view interferometric SAR data gets feasible. IFSAR data is corrupted by blur, speckle noise, and other view dependent effects as e.g., layover and shadows. Especially in case of buildings, these phenomenological features may also provide valuable information about the underlying structure. In this paper we...

The Solar Envelope is a three dimensional envelope on a site which ensures adjacent neighbors a specified minimum direct solar access time per day throughout the year. The solar envelope was developed as a tool to give buildings in an urban setting the mutual opportunity to employ passive and active solar design strategies. Parametric computeraided-design (CAD) environments significantly ease t...

Building a map of the environment is a prerequisite for mobile robot navigation. In this paper, we present a semantic map building method for indoor navigation of a robot using only the image sequence acquired by a mon‐ ocular camera installed on the robot. First, a topological map of the environment is created, where each key frame forms a node of the map represented as visual words (VWs). The...

The ‘wind-rain’ house has a courtyard with glazed roof, which allows more direct sunlight to come into indoor spaces during the winter. The glazed roof can be partially opened or closed and automatically controlled to provide natural ventilation in order to adjust for indoor thermal conditions and the roof area can be shaded by reflective insulation materials during the summer. Two field studie...
