The unpredictable nature of wind energy makes its integration to the electric grid highly challenging. However, these challenges can be addressed by incorporating storage devices (batteries) in the system. We perform an overall assessment of a single domestic power system with a wind turbine supported by an energy storage device. The aim is to investigate the best operation mode of the storage ...

We study the properties, design, implementation and performance of trusted storage, an architecture that ensures the integrity, confidentiality and accountability of data, by enforcing storage policies at the lowest layer of a storage system, within the hardware and firmware of disk enclosures. The guarantees provided by trusted storage depend only on the integrity and correctness of the truste...

In this paper, the effect of a static synchronous compensator (STATCOM) influence on the frequency of islanded microgrids based on frequency control using fuzzy cooperative control is investigated. To achieve fast frequency control, instantaneous power balance between generation and consumption is inevitable, and it can be supplied through energy storage systems such as battery with a proper fr...

The current storage models for Object-Oriented DataBase (OODB), which organize data as objects according to the Object-Oriented Data Model (OODM), are mainly established on the block storage devices. In this way, the storage manager does not have detailed knowledge of the characteristics of the underlying storage devices, and the storage subsystem does not have the semantic knowledge of the dat...

Device Locks are mechanisms used in distributed environments to facilitate mutual exclusion of shared resources. They can further be used to maintain coherence of data that is cached in several locations. The locks are implemented on the storage devices and accessed with the SCSI device lock command, Dlock. This paper presents the Dlock command and discusses how it can be used as a mutual exclu...

There are available today many data storage devices that serve the diverse application requirements of the consumer, professional entertainment, and computer data processing industries. Storage technologies include semiconductors, several varieties of optical disk, optical tape, magnetic disk, and many varieties of magnetic tape. In some cases, devices are developed with specific characteristic...

Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important for accurate assessment of indoor and outdoor exposure. Solid phase microextraction (SPME), needle trap device (NTD) and hollow fiber- liquid phase microextraction (HF-LPME) are...

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...

Emerging non-volatile memory technologies as a disk drive replacement raise some issues of software stack and interfaces, which have not been considered in disk-based storage systems. In this work, we present new cooperative schemes including software and hardware to address performance issues with deploying storage-class memory technologies as a storage device. First, we propose a new polling ...
