Abstract:

By reducing ships’ fuel consumption, shipowners can achieve lower operating costs while at the same time reducing their impact on the environment. This report is a study of different measures that can be taken in order to improve ships’ energy efficiency, and a study of how various engine parameters can be related to efficient running of the engine. Several measures have been assessed and related to a specific ship’s energy profile in order to find the fuel and diesel oil savings potential. The ship’s profile has been updated largely based on the different manufacturers’ own estimations of the

Abstract:

Diesel engine and generator sets (gensets) have been extensively used for standby and remote power generation over the past hundred years. Due to their use for standby power, these diesel gensets are designed to operate in conjunction with the grid, which relates to a fixed speed operation with a 60 Hz AC output. For operation in remote conditions, such as military and disaster relief applications, this fixed speed operation results in limiting the power output available from the engine, as well as the overall efficiency of the system. The removal of this grid connectivity requirement coul

Abstract:

In this thesis, we analyze allocation of two separate resources in wireless networks: transmit power and buffer space. Controlled allocation of power can provide good performance for both users and the network. Although centralized mechanisms are possible, distributed power control algorithms are preferable for efficient operation of the network. Viewing distributed power allocation as the collection of rational decisions of each user, we make game theoretic problem formulations, devise distributed algorithms and analyze them. First, equilibrium analysis of a vector power control game based on

In the face of the internationally tightened requirements and regulations for CO2 emissions from the transportation sector, waste heat recovery using a thermoelectric generator (TEG) has become the most significant research interest. A vehicular TEG, converting otherwise wasted thermal energy from engines to electricity directly for use in the vehicle systems, is a promising approach for vehicle original equipment manufacturers (OEMs) to reduce fuel consumption and lower CO2 emissions.

The aim of this study was to investigate the technologies and policy instruments available to improve efficiency in data centres. Data centres consume a significant and increasing proportion of the world’s electricity, and much of this electricity is consumed in cooling the computing equipment housed in these facilities. Significant potential exists to improve the efficiency of cooling in data centres. One popular method for improving efficiency in data centre cooling is to physically separate the hot and cold air streams using ‘aisle containment’ systems. This has been shown to reduce ‘bypass

We found that the entropy production rate of distillation could be reduced up to 50%. In order to achieve this reduction, heat exchangers were added on each tray. The characteristics of an optimum distillation column were presented. Furthermore, the entropy production rate of a SO<sub>2</sub> converter

Abstract:

To allow access to the network at all times a base station has to continuously stay active. While being active, a base station does not usually transmit data constantly. Typically, the base stations either send out lots of data or barely anything at all, yet, the network is actively drawing power the whole time. Succeeding in lowering the power consumed when the data rate is often so low would therefore lead to great benefits, both economically and environmentally, as well as new prospects of innovation in engineering.

Imbalances are controlled by many decisions made at various stages before real-time. A decision can be to increase the flexibility in production and consumption.

Abstract:

Security Operation Centers (SOCs) have become an integral component of business organizations all over the world. The concept of a SOC has existed for a few years now yet there is no systematic study documenting the occurrences of their operations. A lack of documented operational knowledge makes it a challenge for security researchers interested in improving operational efficiency through algorithms, tools, and processes. SOC environments operate under a secrecy culture as a result of which researchers are not trusted by analysts and their managers. This lack of trust leads to only superfi

Abstract:

Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. However, due to the deregulation of electricity markets and the growth in the share of power generation by uncontrollable renewable energies such as wind and solar, power system simulations are more challenging than earlier. Thus, new techniques for simplifying these simulations are needed. One important example of such simplification techniques is the power system reduction. Power system reduction can be used at least for four different purposes:

Abstract:

Every positive integer has a unique radix 2 representation which uses the digits {0,1}. However, if we allow digits other than 0 and 1, say {0,1,-1}, then a positive integer has many representations. Of these <i>redundant</i> representations, it is possible to choose one that has few nonzero digits. It is well known that using representations of integers with few nonzero digits allows certain algebraic operations to be done more quickly. This thesis is concerned with various representations of integers that are related to efficient implementations of algebraic operations in crypto
