This study investigated the extent to which subjectively and objectively measured street-level perceptions complement or conflict with each other in explaining property value. Street-scene can be assessed from self-reported survey questions, quantified land use data pixel ratios of physical features extracted street-view imagery. Prior studies mainly relied on objective indicators describe found that a better street environment is associated price premium. While very few have addressed...

Cities are frontlines to tackle climate change challenges including the urban heat island (UHI) effect. The classification and mapping of local zones (LCZs) can effectively consistently describe surface structure across regions. This study pays attention two mainstream methods in classifying LCZs, namely, by using geographic information system (GIS) data such as building footprints or remote sensing (RS) satellite images. Little has been done compare divergence coherence abovementioned...

As for the stability control problem rotary inverted pendulum, two closed-loop fractional order PID scheme is used to pendulum. First, mathematical model of pendulum established according Euler-Lagrange equation. Then, a controller designed based on Bode ideal transfer function. Finally, (FOPID) controller, PD (FOPD) and integer (IOPD) are applied system which Quanser company loop simulation experiment platform. The results show that FOPID better than FOPD IOPD in stabilizing angle closest...
