Surface passivation is a promising technique to improve the power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs). Upper surface passivation has been widely used to passivate surface traps which are responsible for interfacial recombination loss. The bottom surface (or...

Purpose This study aims to the complex and unpredictable terrain environment of the Qinghai-Tibet Plateau scientific research station, such as cement road, wetland, gravel desert, snowfield, ice surface, grassland, slimy ground, steep slope, step, etc., a reconfigurable walking mechanism based...

Employment is the greatest livelihood. Whether the impact of industrial robotics technology materialized in machines on employment in the digital age is an “icing on the cake” or “adding fuel to the fire” needs further study. This study aims to analyze the impact of the installation and...

With the rapid development of big data and the national big data strategy is put forward, the Web server cluster facing more complex and severe challenges. The traditional load balancing algorithm has obvious limitations. This paper proposes a dynamic load-balancing model based on the SSAWF...

Purpose – The purpose of this paper is to propose a method that calibrates the hand-eye relationship for eye-to-hand configuration and afterwards a rectification to improve the accuracy of general calibration. Design/methodology/approach – The hand-eye calibration of eye-to-hand...

This research investigates the drivers and barriers to the adoption of FTTx broadband across the world. More specifically it explains the reason for wide disparity in adoption between countries of similar socio-economic structure. The barriers and drivers for both the demand for and the supply...

This research analyses the adoption of very high speed broadband (e.g. fiber to the home) and provides diffusion forecasts (i.e. yearly changes in subscription) for countries across the world. We present econometric models which estimate the diffusion rate according to a set of supply and demand...

Prior theoretical models on investors' disagreement and trading volume such as Banerjee and Kremer (2010) and Banerjee (2011) assume the convergence speed of investors' disagreement is exogenously given and constant over time. This paper extends the prior literature by including the...

This research identifies the reason for wide disparity in the investment in high speed broadband infrastructure through technologies such as Fiber-to-the-Home (FTTH) and Fiber-to-the-Building (FTTB) i.e. FTTx broadband. We employ a panel data analysis technique to identify the factors impacting...
