Abstract:

The thesis describes an investigation of the kinetics of certain electrochemical energy storage systems. The work mainly involves A.C. impedance measurements made over a wide frequency range on some primary and secondary cells. In a number of cases this was sufficient to establish the electrochemistry and evaluate the magnitudes of the circuit elements of the analogue for the cell. In some other cases (secondary cells) the electrode behaviours of anode and cathode had to be established in order to produce the composite cell behaviours.

Koeberg Nuclear Power Station (KNPS) is the only nuclear power station in Africa and it stores its spent nuclear fuel (SNF) onsite in the spent fuel pool (SFP). Additional aged SNF assemblies are stored in dry storage casks in a facility located on the KNPS site. This minor research dissertation aims at evaluating various dry storage cask found in open literature. The dissertation provides an overview of cask types, heat transfer, radiation shielding and storage facility types. Specific criteria are required in the selection of casks and the storage facility to house the casks on site. The sel

Abstract:

To meet the predicted increase in demand for energy storage in tomorrow's society, the development of inexpensive, flexible, lightweight and sustainable energy-storage materials is essential. In this respect, devices based on electroactive organic molecules, such as conducting polymers, are highly interesting. The aim of this thesis was to evaluate the use of nanocellulose as a matrix material in composites of cellulose and the electroactive polymer polypyrrole (PPy), and the use of these composites in all-polymer paper-based energy-storage devices.

Abstract:

INTEGRATING local renewable resources into the low voltage distribution system can create weak micro-grids with limited power capabilities and challenging control requirements. The low inertia in these micro-grids can result in significant frequency excursions when large load or generation changes are seen. Micro-grids may also be more susceptible to high harmonic distortion in their voltage due to non-negligible supply impedance. This calls for advance control techniques to regulate frequency and maintain voltage at the standards required of the utility grid. Failure to do so may incur discon

Abstract:

The world’s increased energy storage demand, as well as the environmental concerns related to the combustion of fossil fuels, has triggered a transition to intermittent renewable energy sources as well as to electrical and hybrid vehicles. Current day rechargeable batteries are, due to the invention and development of lithium ion batteries, technologically well positioned to answer to some of these demands. Conventional batteries, however, utilize inorganic materials of limited supply that require large amounts of energy during refining and processing. The materials also add a significant cost

Abstract:

The consequences of over-reliance on fossil fuels for energy supply, namely climate change and security of supply, are pushing for the use of local, renewable energy sources which are usually variable in nature, prompting the need for energy storage. Today, there is a trend towards distributed energy storage, justified by the distributed nature of renewable energy sources and the important share of energy consumption in buildings. Important information on such small scale energy storage installations, however, is still missing and the results of the existing literature vary widely. To account

Abstract:

Europe aims for a transition towards less greenhouse gas emission and dependency on fossil fuels. The integration of intermittent renewable energy sources, as wind or solar power, can be facilitated by, among others, temporally decoupling demand and supply of electricity. If technologies for electrical energy storage are profitable, wide implementation could support the transition. Therefore, this study assesses the revenues and costs of long-term storage technologies and evaluates the possibility to stack several services provided by a storage unit to fully utilise it.

Dependence of the noise on various system parameters such as focal length, pixel size, number of pixels and material parameters are studied. An algorithm is developed to design pseudorandom phase masks which can improve the signal-to-noise ratio for a given system. The noise reduction

One major security concern is the integrity and freshness of data stored on the cloud, that is, whether a storage provider can guarantee that the data received by its clients is always correct and up-to-date. Recent studies have focused o

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2011.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 83-85).<br>Quantum networks enable the long-distance communication of quantum states through teleportation, but require, in advance, the robust distribution of entanglement between relevant parties. Engineering these networks requires quantum interconnects, which convert quantum states in one physical system to those of another reversibly, and with high fidelity. In this thesis, we describe imple

Thesis (M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 1998.<br>Includes bibliographical references (p. 113-118).<br>Given today's tangle of digital information, one of the hardest tasks for computer users of information systems is finding anything in the mess. For a number of well documented reasons including the amazing growth in the Internet's popularity and the drop in the cost of storage, the amount of information on the net as well as on a user's local computer, has increased dramatically in recent years. Although this readily availa

Abstract:

There is considerable growth in the renewable energy sector to contribute to sustainable development, environmental conservation and most importantly to provide affordable energy to isolated rural communities of sub-Saharan Africa. Renewable energy sources such as solar and wind require energy storage since the source of energy is intermittent. Electrochemical batteries especially from lead acid are commonly used to store energy in Solar Home Systems (SHS) for rural electrification in sub-Saharan Africa. Disadvantages such as low efficiencies, low life cycle costs, high maintenance, comparativ

Abstract:

In this thesis, we first define the concept of scalability and describe its three types, namely SNR, spatial and temporal scalability. This is followed by a review of the various techniques reported in the literature for achieving scalable image compression. We then investigate the algorithms for scalable image compression within the framework of JPEG standard. An extension to the hierarchical mode algorithm of JPEG is presented which provides an improved coding performance. This is followed by evaluation of the performance of these algorithms for image transmission over ATM networks. JPEG pro
