With the increasing popularity of open-source platform Hadoop, the meteorological industry is available to create a Meteorological Cloud (MeteCloud) platform to store and deploy applications. In this paper, we propose an idea to build the MeteCloud platform for meteorological departments using Hadoop. We also present a backup policy for meteorological data. In addition, one kind of storage proc...

Analytical models are mathematical models built after a thorough analysis of the underlying system. The models work as follows: they use information about the workload and the underlying system to predict the performance for different configurations. For example, an analytical model of the cache requires a trace of cache accesses, the cache replacement policy, and the cost of cache hit and miss...

Grid computing enables the virtualization of distributed computing and data resources such as processing, network bandwidth and storage capacity to create a single system image. The complexity of resource management in Grid significantly increases as the grid computing grows. To solve the problem we propose grid policy administrator with MDP-based resource management scheme. The grid policy adm...

Traditional memory allocation mechanisms are not suitable for new DRAM-based storage systems because they use memory inefficiently, particularly under changing access patterns. In contrast, a log-structured approach to memory management allows 80-90% memory utilization while offering high performance. The RAMCloud storage system implements a unified log-structured mechanism both for active info...

We investigate the problem of storage assignment in a warehouse served by milkrun logistics, i.e. vehicles circulating according to a pre-defined schedule between the warehouse and the production facilities of the plant. Such a logistic system results in an easy-to-characterize correlation among the request probabilities of the items in the warehouse. A MIP model is proposed that exploits this ...

In recent years, we have seen the development of key assignment schemes that use cryptography to enforce time-based authorization policies. One of the most important aspects of these schemes is the balance between the time required to derive keys and the amount of storage required for the public information from which keys are derived. The derivation time and storage are dependent on the number...

This paper presents a policy-based framework for managing shared data among distributed participants in a dynamic collaboration. First, we identify three different types of entities, namely resources, participants and their relations, and the set of policies applicable to them. We then propose an integrated framework to provide a solution for managing shared data in dynamic collaborations. We d...

A tight upper bound of the lumped disk seek time for the Scan disk scheduling policy is presented. The tight upper bound is based on an accurate disk seek time model. One of the most important applications of the tight upper bound is in multimedia storage system design. Without a tight upper bound based on an accurate disk seek time model, the designers of multimedia storage systems would be fo...

Driven by policy changes and technological advancement, wind power installations are booming as compared to any other types of power generation. However, the increased penetration of renewable generation in the power systems has resulted in high level of curtailment. Advanced energy storage technologies have been increasingly scrutinized as a feasible mitigation option in smart grids. This pape...
