Efficient Index Maintenance for Moving Objects with Future Trajectories

Recently, more research has been conducted on moving object databases (MOD). Typically, there are three kinds of data for dynamic attributes in MOD, i.e., historical, current and future. Although many index structures have been developed for the former two types of data, there is not much work to deal with the future data. In particular, the problem of index update has not been addressed with e...

Performance Evaluation of SSD-Index Maintenance Schemes in IR Applications

— With the advent of flash memory based new storage device (SSD), there is considerable interest within the computer industry in using flash memory based storage devices for many different types of application. The dynamic index structure of large text collections has been a primary issue in the Information Retrieval Applications among them. Previous studies have proven the three approaches to ...

Integrated Inspection Planning and Preventive Maintenance for a Markov Deteriorating System Under Scenario-based Demand Uncertainty

In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied.  The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...

Influences of Track Structure, Geometry and Traffic Parameters on Railway Deterioration

The roles of the several parameters that influences railway track deterioration most, are examined in this research with a view to make railway track maintenance more effective and cost efficient. The results presented are based on a comprehensive study of railway track degradation on super structure, sub-structure and geometrical aspects. The changes in TQI (Track Quality Index), the track set...
