In the past decade wind-based electricity generation has grown rapidly, and is likely to grow even more in the future. Since generation sites—wind farms—tend to be remote, they require transmission lines to transport electricity to markets. These wind farms can be augmented by co-locating them with an electricity storage facility, for example, an industrial battery. This storage facility enable...

The picking process is a critical supply chain component for many companies. A proper warehouse configuration, storage policy, trays replenishment policy, and other factors are also important to reduce not only the delivery time, but also increase productivity while maintaining quality factors at competitive costs. This paper presents an integrated approach to tackle the complexity of warehouse...

There has recently been resurgent interest in energy storage, due to a number of developments in the electricity industry. Despite this interest, very little storage, beyond some small demonstration projects, has been deployed recently. While technical issues, such as cost, device efficiency, and other technical characteristics are often listed as barriers to storage, there are a number of non-...

This paper examines the argument for dataflow architectures in “Two Fundamental Issues in Multiprocessing[5].” We observe two key problems. First, the justification of extensive multithreading is based on an overly simplistic view of the storage hierarchy. Second, the local greedy scheduling policy embodied in dataflow is inadequate in many circumstances. A more realistic model of the storage h...

MEMS-based storage devices should be energy efficient for deployment in mobile systems. Since MEMS-based storage devices have a moving media sled, they should be shut down during periods of inactivity. However, shutdown costs energy, limiting the applicability of aggressive shutdown decisions. The media sled in MEMS-based storage devices is suspended by springs. We introduce a policy that explo...

This paper presents an efficient content-based version management system for managing XML documents. Our proposed system uses complete deltas for the logical representation of document versions. This logical representation is coupled with an efficient storage policy for version retrieval and insertion. Our storage policy includes the conditional storage of complete document versions (depending ...

Cloud storage service is one of cloud services where cloud service provider can provide storage space to customers. Because cloud storage service has many advantages which include convenience, high computation and capacity, it attracts the user to outsource data in the cloud. However, the user outsources data directly in cloud storage service that is unsafe when outsourcing data is sensitive fo...

We introduce a racing model with multiple product generations, product innovation, spin-outs, and licensing. Industry conditions and innovation characteristics affect who wins the race and who markets the resulting product. Small firms market their innovations when they pioneer a new generation or improve quality in a young generation and license their innovations in mature generations. If old ...

Capacity demands for computer memory are increasing. A multilevel storage system provides an economically feasible solution without seriously affecting the total response time. An M-level storage system is considered in this paper. The capability of a digital computer with a multilexel storage system is best enhanced in a multiprogramming environment. In a high level storage system, determinati...
