This paper considers short-term energy management of a wind power plant with battery storage, in order to smooth the variations of power output to the external grid. An optimal on-line heuristic is developed for a control environment, in which decision-making is independent of wind historical data and forecasts.

The use of flash-based solid state drives (SSDs) in storage systems is growing. Adding SSDs to a storage system not only raises the question of how to manage the SSDs, but also raises the question of whether current buffer pool algorithms will still work effectively. We are interested in the use of hybrid storage systems, consisting of SSDs and hard disk drives (HDDs), for database management. ...

© The Ecological Society of America www.frontiersinecology.org E of the principal greenhouse gas (GHG), carbon dioxide (CO2), are driven primarily by the burning of fossil fuels, but the Earth’s biosphere also plays a major role in the global carbon (C) budget. Forest biomes are an important component of the global C budget, because of the large quantities stored in live biomass, detritus, and ...

As users’ and companies’ dependence on shared, networked information services continues to increase, we will see continued growth in large data centers and service providers. This will happen both as new services arise, and as services and servers are consolidated on one hand (for ease of management, outsourcing, and reduced duplication), and further distributed on the other hand (for fault-tol...

Existing garbage collection algorithms for the flashbased storage use score-based heuristics to select victim blocks for reclaiming free space and wear leveling. The score for a block is estimated using metadata information such as age, utilization, and erase count. To quickly find a victim block, these algorithms need to maintain a priority queue in the SRAM of a flashbased storage controller....

Over the last few years there has been a revolution in DNA sequencing technology that has brought down the cost of DNA sequencing and made the sequencing of an increasing number of genomes both feasible and cost effective. There has also been a dramatic shift in the type of sequence data being generated, with vast numbers of short reads or pairs of short reads replacing the traditional relative...

Motivated by the importance of energy storage networks in smart grids, we provide an algorithmic study of the online energy storage management problem in a network setting, the first to the best of our knowledge. Given online power supplies, either entirely renewable supplies or those in combination with traditional supplies, we want to route power from the supplies to demands using storage uni...

Beginning with MVS/ESA SP3.1.3, IBM redesigned the logical swapping algorithms, integrated the page stealing process with logical swapping, and revised the algorithms controlling processor storage (central storage and expanded storage). This logic has been enhanced with MVS/ESA SP4.2 and SP4.3. A major goal of the changed logic is to take advantage of increasingly large amounts of processor sto...

Data management and monitoring is an important issue in scientific computation. Scientists want to access their data as quickly as possible. Some experiments need to store a lot of data which have to be secure. By saying this we mean that this data can not disappear or be damaged also the data storage should be as cheap as possible. In this paper we present an approach to the automation of moni...

Perspective is a decentralized data management system for the growing collection of consumer electronics that store and access digital content. Perspective uses a new construct, called the view, to concisely describe which data objects each device may store and access. By knowing the views in the system, a device can know which devices may need to hear about any particular update and which devi...
