Partial Answers for Unavailable Data Sources
Many heterogeneous database system products and prototypes exist today; they will soon be deployed in a wide variety of environments. Most existing systems suffer from an Achilles’ heel: they ungracefully fail in presence of unavailable data sources. If some data sources are unavailable when accessed, these systems either silently ignore them or generate an error. This behavior is improper in e...
متن کاملObserving long-term changes in rice phenology using NOAA–AVHRR and DMSP–SSM/I satellite sensor measurements in Punjab, India
The paper reports a unique observation from remote sensing records that the temporal rice growth pattern in terms of time of emergence and peak vegetation stage has been advanced by 3–4 weeks in Punjab, India from 1981 to 2000. Analysis was carried out using multi-temporal remote sensing data from the optical sensors such as Advanced High Resolution Radiometer (AVHRR) and the passive microwave ...
متن کاملThe Artificial Sky Brightness in Europe Derived from Dmsp Satellite Data
We present the map of the artificial sky brightness in Eu-rope in V band with a resolution of approximately 1 km. The aim is to understand the state of night sky pollution in Europe, to quantify the present situation and to allow future monitoring of trends. The artificial sky brightness in each site at a given position on the sky is obtained by integration of the contributions produced by ever...
متن کاملInterference effects from grammatically unavailable constituents during sentence processing.
Evidence from 3 experiments reveals interference effects from structural relationships that are inconsistent with any grammatical parse of the perceived input. Processing disruption was observed when items occurring between a head and a dependent overlapped with either (or both) syntactic or semantic features of the dependent. Effects of syntactic interference occur in the earliest online measu...
متن کاملEvaluating Saturation Correction Methods for DMSP/OLS Nighttime Light Data: A Case Study from China's Cities
Remotely sensed nighttime lights (NTL) datasets derived from the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) have been identified as a good indicator of the urbanization process and have been widely used to study such demographic and economic variables as population distribution and density, electricity consumption, and carbon emission. However, one issue m...
