We seek to extract and explore statistics that characterize New York City traffic flows based on 700 million taxi trips in the 2010–2013 New York City taxi data. This paper presents a two-part solution for intensive computation: space and time design considerations for estimating taxi trajectories with Dijkstra's algorithm, and job parallelization and scheduling with HTCondor. Our contribution is...
By adjusting structures of the nozzle and mixing-chamber , effects of the structure on the steam ejector performance were analyzed. An improved CFD program which was proved suitable for simulating flow profile in a steam ejector formerly was used here. The results of this study would be useful for designing a steam ejector with high performance when working condition was given.
Identifying proper business processes, formalizing and documenting them has always been a challenge. Maintaining them in synchronization with changing business needs makes the problem harder. It becomes even harder when business processes are fully or partially implemented in IT systems where changes to the business cause changes in IT configurations. This paper presents an approach how IT configurations...
We introduce a new cache architecture that can be used to increase performance and reduce energy consumption in Network Processors. This new architecture is based on the observation that there is a strong correlation between different memory accesses. In other words, if load X and load Y are two consecutively executed load instructions, the offset between the source addresses of these instructions...
In spite of the widespread acceptance by academics and practitioners of structured programming precepts, relatively few formal empirical studies have been conducted to obtain evidence that either supports or refutes the theory. This paper reviews the empirical studies that have been undertaken and critiques them from the viewpoints of the soundness of their methodology and their ability to contribute...
