MOTIVATION Recently there has been increasing interest in the effects of cell mixture on the measurement of DNA methylation, specifically the extent to which small perturbations in cell mixture proportions can register as changes in DNA methylation. A recently published set of statistical methods exploits this association to infer changes in cell mixture proportions, and these methods are prese...

This paper analyzes a discrete-time infinite-buffer Geo/Geo/2 queue, in which the number of servers can be adjusted depending on the number of customers in the system one at a time at arrival or at service completion epoch. Analytical closed-form solutions of the infinite-buffer Geo/Geo/2 queueing system operating under the triadic (0, Q N, M) policy are derived. The total expected cost functio...

2. OVERVIEW OF GIR SYSTEM 2.1 Pre-process The GIR system requires a text index and a geographic index. As the text index, those created for existing full-text search can be used. The geographic index is made by using NE recognizer, which locates place name expressions in texts as geo-references and geo-coder, which assigns coordinates to each geo-reference. The geographic index of our method al...

Groundwater is of the most reliable sources of water for agriculture and drinking. In coastal areas due to saltwater intrusion, determine the interface between fresh and salt water for residents of these areas is very important. In this study, the characteristics of coastal aquifers West and East Babolsar, using geoelectrical studies and geo-electromagnetic studied that these methods are of the...

In the last 30 years, China’s economic power has experienced great changes and has brought about a profound impact on the world economy. This led us to ask a question: do changes in China’s economic power shift the geo-economic relationships between China and its neighboring countries? To answer this question, we researched the evolution of geo-economic relationships between China and the Assoc...

In this paper, we propose an approach for locating an additional facility—to add to a chain of existing facilities—based on geo-statistical methods. This approach does not make assumptions on customer demand behavior with respect to distance from the nearest facility (as is commonly made in location models) but rather implicitly takes into account intrinsic factors. The goal is to maximize the ...
