Consider the Geo/Geo/1 queue with impatient customers and let X reflect the patience distribution. We show that systems with a smaller patience distribution X in the convex-ordering sense give rise to fewer abandonments (due to impatience), irrespective of whether customers become patient when entering the service facility. © 2005 Elsevier B.V.

background: sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. this study was carried out for assessing co, ni, and zn in sediment samples of mighan wetland using geo-accumulation index in 2013. methods:the sediment samples were taken from 11 stations. the samples were subjected to bulk digest...
Modern cloud infrastructures are geo-distributed. Geodistribution offers many advantages but can increase the total cloud capacity required. To achieve low latency, geo-distribution forfeits statistical multiplexing of demand that a single data center could benefit from. Geo-distribution also complicates software design due to storage consistency issues. On the other hand, geodistribution can l...
Rich geo-textual data is available online and the data keeps increasing at a high speed. We propose two user behavior models to learn several types of user preferences from geo-textual data, and a prototype system on top of the user preference models for mining and search geo-textual data (called PreMiner) to support personalized maps. Different from existing recommender systems and data analys...
The Group on Earth Observations Biodiversity Observation Network (GEO BON) has been in formal existence for three years, following several years of design and discussion. It is the realisation of the biodiversity societal benefit area envisaged in the GEO System of Systems (GEOSS). GEO BON links together existing networks, each covering particular aspects of biodiversity or parts of the world, ...
