Vegetation index (VI) time series derived from satellite sensors have been widely used in the estimation of vegetation parameters, but quality VI is easily affected by clouds and poor atmospheric conditions. The function fitting method a effective noise reduction technique for series, it vulnerable to noise. Thus, ancillary data about are utilized alleviate interference However, this approach l...

This paper describes our experiments with unsupervised methods for back-of-the-book index construction. Through comparative evaluations performed on a gold standard data set of 29 books and their corresponding indexes, we draw conclusions as to what are the most accurate unsupervised methods for automatic index construction. We show that if the right sequence of methods and heuristics is used, ...

Coccidioidomycosis is a fungal infection endemic to the southwestern United States, particularly Arizona and California. Its incidence has increased, potentially due in part to the effects of changing climatic variables on fungal growth and spore dissemination. This study aims to quantify the county-level vulnerability to coccidioidomycosis in Arizona and California and to assess the relationsh...

This work provides algorithms and heuristics to index text documents by determining important topics in the documents. To index text documents, the work provides algorithms to generate topic candidates, determine their importance, detect similar and synonym topics, and to eliminate incoherent topics. The indexing algorithm uses topic frequency to determine the importance and the existence of th...

One of the useful method to improve a designed control system performance is utilization of the future desired signal and/or disturbance signal, if possible. Until now, optimal preview control system and preview pre-compensator are considered on the basis of optimal regulator theory and model matching approach. Effectiveness of the preview control system is shown in the application to servo sys...

A citation analysis of core library and information science journals was conducted to identify factors associated with subjective rankings of a journal's value in promotion and tenure decisions. Prestige rankings from a 1982 survey of ARL directors and library school deans were correlated with nine citation measures: total citation count, impact factor, immediacy index, references per paper, Pr...

Based on the current state of practice, this paper examines the issues in measuring disaster preparedness, and the process of constructing indicators and indices. Existing indices are examined, and a proposed framework of creating a Disaster Preparedness Index (DPi), and Resiliency Index (Ri) with a suggested list of measurement indicators is put forward. The framework and indicator list is unw...

[Purpose] Maintaining high quality of life is crucial for the rehabilitation of patients with Parkinson's disease. The quality of life scales currently in use do not assess all quality of life domains or their importance for each individual. Therefore, a new quality of life measure, the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting, was used to investigate quality o...
