Abstract Real-Time Precise Point Positioning (RT-PPP) has been one of the research hotspots in GNSS (Global Navigation Satellite System) community for decades. Real-time precise products satellite orbits and clocks are prerequisite RT-PPP. Thus, it is great importance to investigate current multi-GNSS real-time State Space Representation (SSR) from different analysis centers. In this article, S...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

cache, performance evaluations, prefetching As processor clock rates increase the memory hierarchy is hard pressed to keep up. One way of mitigating the increasing gap between processor and memory is by prefetching items from memory before they are requested by the processor. Various algorithms perform better or worse depending on how accurately they predict the needed items and in how timely a...

To become a medical home, providing patients with comprehensive, coordinated primary care, practices need to meet multiple requirements. These include some form of round-the-clock access for patients; managing chronic or complex conditions; carrying out timely, clear communication between providers and patients; and engaging in continuous quality improvement. The recently enacted health reform ...

There has been a rapid growth in demand for computational power which has led to the creation of large data centers. These consume enormous amounts of electrical power resulting in high cost of operation and carbon dioxide emissions. The computing model of cloud usage is also increasing the power consumption by the ICT equipments involved in between a service provider and the user across the ne...

In this study, the authors examine the extent to which the characteristics of caregivers or recipients determine the probability that caregivers stop being caregivers. We find that caregivers' characteristics such as working outside their homes, raising children, or having their own health problems do not increase this probability. Nor does the emotional distress of caregiving increase the prob...

Satellite orbit error and clock bias are the keys to precise point positioning (PPP). The traditional PPP algorithm requires precise satellite products based on worldwide permanent reference stations. Such an algorithm requires considerable work and hardly achieves real-time performance. However, real-time positioning service will be the dominant mode in the future. IGS is providing such an ope...

The University Teaching Hospital in Lusaka, Zambia, is the nation’s premier tertiary referral hospital and a teaching centre for the University of Zambia as well as a research centre of excellence. It was one of the five sites chosen as part of a multinational injury surveillance project conceived to provide preliminary data in response to observations made by public health agencies such as the...

A surge of interest in data-intensive computing has led to a drastic increase the demand for data centers. Given this growing popularity, centers are becoming primary contributor increased consumption energy worldwide. To mitigate problem, paper revisits DVFS (Dynamic Voltage Frequency Scaling), well-known technique reduce usage processors, from viewpoint distributed systems. Distributed system...
