Traditionally, inventory models with trade credit policy deal with contain demand or merely dependent on the retailing price. Therefore, this paper tries to incorporate the retailer’s inventory-dependent demand and storage space limited in the retailer’s inventory model, which will make the decision-maker of inventory system to know whether to rent RW and how to order. Two easy-touse theorems a...

The Mach external pager interface allows applications to supply their own routines for moving pages to and from second-level store. Mach doesn’t allow applications to choose their own page replacement policy, however. Some applications have access patterns that may make least recently used page replacement inappropriate. In this paper, we describe an extension to the external pager interface th...

This paper describes a network storage system, called Venti, intended for archival data. In this system, a unique hash of a block’s contents acts as the block identifier for read and write operations. This approach enforces a write-once policy, preventing accidental or malicious destruction of data. In addition, duplicate copies of a block can be coalesced, reducing the consumption of storage a...

We present a generic API suitable for provision of highly generic storage facilities that can be tailored to produce various individually customised storage infrastructures. The paper identifies a candidate set of minimal storage system building blocks, which are sufficiently simple to avoid encapsulating policy where it cannot be customised by applications, and composable to build highly flexi...

The main issues characterizing current video applications are their strong requirements for huge storage spaces and their need for timing synchronization Video data storage is a critical research topic due to the so called I O bottle neck problem which a ects the quality of service of video applications This paper introduces a two level video data representation model in order to guide video da...

We present and benchmark an approximate dynamic programming algorithm that is capable of designing nearoptimal control policies for time-dependent, finite-horizon energy storage problems, where wind supply, demand and electricity prices may evolve stochastically. We found that the algorithm was able to design storage policies that are within 0.08% of optimal in deterministic comparisons and wit...

EEcient storage management of objects is an important part of any persistent object system. Storage management algorithms, such as those for clustering, caching, and garbage collection, are often complex, since they must simultaneously satisfy a number of constraints, including low CPU overhead, minimum space usage, and low latency. We have designed a simulation system that can be used to evalu...

Storage and secondary use of bloodspots collected for newborn screening raises controversies because of the particularly sensitive nature of the information that can be derived from them and the lack of national standards and consistent provincial policies that can serve to guide storage facilities. This report, derived through a review of Canadian and provincial policy statements, a survey of ...
