Processing high-throughput data-streams has become a major challenge in areas such as real-time event monitoring, complex dataflow processing, and big data analytics. While there been tremendous progress distributed stream processing systems the past few years, low-latency (a.k.a. high sustainable-throughput ) requirement of modern applications is pushing limits traditional infrastructures. Thi...

A flight of marine terraces along the central California coastline provides a unique setting for the study of topographic evolution. Wavecut platforms manfled by 2-6 m of marine terrace cover deposits are separated by10-50 m tall decaying sea cliffs. Palcocliff edges become more rounded with age, yet the details of the profries and frequent bedrock exposure on the upper slopes imply weatheringl...

Many ephemeral streams in western North America flowed over smooth valley floors before transformation from shallow discontinuous channels into deep arroyos. These inherently unstable streams of semiarid regions are sensitive to short-term climatic changes, and t’o human impacts, because hillslopes supply abundant sediment to infrequent large streamflow events. Discontinuous ephemeral streams a...

In this paper, we analyze the thermal radiation and chemical reaction impacts on MHD peristaltic motion of the Eyring-Powell fluid through a porous medium in a channel with compliant walls under slip conditions for velocity, temperature, and concentration. Assumptions of a long wave length and low Reynolds number are considered. The modeled equations are computed by using the perturbation metho...

Surface runoff is one of dominant factors in hydrological environment, whose spatial pattern and hydrological feature represent the composite factors of its corresponding drainage. And the stream network nodes present spatial structure and attributes of geography and hydrology in a watershed. A quantified method to analyze stream network nodes is proposed in this paper. The typical area of the ...
