We demonstrate here an electrostatic MEMS system capable of transporting particles 5-10pm in diameter in air. This system consists of 3-phase electrode arrays covered by insulators (Figs. I , 2). Extensive testing of this system has been done using a variety of insulation materials (silicon nitride, photoresist, and Teflon), thickness (012pm), particle sizes (11 Opm), particle materials (metal,...

Many errors in software systems do not manifest themselves until the system has been deployed into production use. Fatal errors can have especially severe consequences in such situations as they may completely deny the user any of the service that the program is designed to supply. The standard approach to dealing with errors is to notify the organization that produced the system of the problm,...

Traffic congestion causes huge economic loss worldwide in every year due to wasted fuel, excessive air pollution, lost time, and reduced productivity. Understanding how humans move and select the transportation mode throughout a large-scale transportation network is vital for urban congestion prediction and transportation scheduling. In this study, we collect big and heterogeneous data (e.g., G...

Transportation planning is an important part in the development of a region. An effective transport system and associated urban forms will improve the economic and social opportunities. Accessibility and mobility are the two main parameters which contribute to the effective transportation system. In this paper, the accessibility to the public transportation system is identified for the selected...
