The increasing capacity of modern computers, driven by Moore’s Law, is accompanied by smaller noise margins and higher error rates. In this paper we propose a memory device, consisting of a ring of two identical overdamped bistable forward-coupled oscillators, which may serve as a building block in a larger scale solution to this problem. We show that such a system is capable of storing one bit...

In this master thesis, a model is proposed to enable profitable market participation of wind power plants considering the availability of second-party owned energy storage. A novel concept of storage capacity reservations is presented using which the wind power producer hedges against wind outcomes which are unfavourable with respect to its day-ahead market bids. The idea that wind power produc...

In this information age, importance of data in human life is no more just secondary. Electronics plays a vital role in our daily life. In the present world of electronics, there are various ways that are present for storage of any type of data electronically, today’s most used & portable device is pen drives or USB mass storage devices. Under normal circumstances, as an intermediate device, if ...

In areas with rapidly changing loads of large magnitude, utility companies often experience large deviations in frequency and area control error. Inadvertent tie-line power flow also occurs. The purpose of this research is to examine the effects a large scale energy storage device has on the system response to a rapidly changing load. Two control areas connected by a tie-line are modelled and s...

This paper discusses the use of energy storage device to assist FES-cycling for paraplegics and at the same time to eliminate the dead points of the pedal cycle. Implementation of an energy storage device has many desirable influences on FES-cycling. In this study, simple elastic cables are used as energy storage device. Elastic cables can store elastic potential energy due to either compressio...

Storage device performance prediction is a key element of self-managed storage systems and application planning tasks, such as data assignment and configuration. Based on bagging ensemble, we proposed an algorithm named selective bagging classification and regression tree (SBCART) to model storage device performance. In addition, we consider the caching effect as a feature in workload character...

This paper presents the design and implementation of a mobile storage system called a PersonalRAID. PersonalRAID manages a number of disconnected storage devices. At the heart of a PersonalRAID system is a mobile storage device that transparently propagates data to ensure eventual consistency. Using this mobile device, a PersonalRAID provides the abstraction of a single coherent storage name sp...

In large scale data centers, controlling tail latencies of IO requests keeps storage performance bounded and predictable, which is critical for infrastructure resource planning. This work provides a transparent mechanism for applications to pass prioritized IO commands to storage devices. As a consequence, we observe much shorter tail latencies for prioritized IO while impacting nonprioritized ...

This paper introduces the Object-Based Storage Device (OSD) interface, an extension to the SCSI protocol that was developed by the Storage Networking Industry Association (SNIA) over several years and ratified by ANSI in September 2004. This new command set can be carried over the same physical interfaces as SCSI is today, but it represents a major shift of functionality and intelligence into t...
