Non-CPU devices on a modern system-on-a-chip (SoC), ranging from accelerators to I/O controllers, account for a significant portion of the chip area. It is therefore vital for system energy efficiency that idle devices can enter a low-power state while still meeting the performance expectation. This is called device runtime Power Management (PM) for which(More)
In order to understand the impact of the financial crisis on the software outsourcing enterprises, to recognize the essence of the internal resources and capabilities, and to figure out which element or elements have a huge influence on the competence of the software outsourcing enterprises after the financial crisis, a survey about the software outsourcing(More)
Street parking spots for automobiles are a scarce commodity in most urban environments. The heterogeneity of car sizes makes it inefficient to rigidly define fixed-sized spots. Instead, unmarked streets in cities like New York leave placement decisions to individual drivers, who have no direct incentive to maximize street utilization. In this paper, we(More)
In an era of downsizing and financial cutbacks, the operational efficiency of third party logistics providers dictates their competitiveness and/or survival, in order to help the third party logistics providers in China to enhance their productivity and price leverage in the increasingly competitive third party logistics market, this paper proposes a data(More)
The experiment teaching is very important in a physics course. But the fact is students think and do little during the whole experiments. A virtual physics experiment teaching system (VPETS) with high degree of realism has been developed to improve the experiment teaching. This system enables students to use any PC to do virtual physics experiments just(More)
"Open-source Project for a Network Data Access Protocol (OPeNDAP)" provides a discipline-neutral means of requesting and providing data across the World Wide Web. The paper elaborates on the design and building of the OPeNDAP-based Physical Oceanographic Data Service System of South China Sea, which uses the GDS, TDS and Dapper data servers to implement the(More)
Device drivers are responsible for disabling and enabling devices on a System-on-Chip (SoC) at runtime, a practice known as device runtime Power Management (PM). Based on the observations of drivers and their evolution, we consider it harmful to rely on drivers for device runtime PM. We identify information essential to device runtime PM and show that it(More)
