Life cycle assessment of nuclear-based hydrogen production via thermochemical water splitting using a copper-chlorine (Cu-Cl) cycle by Ahmet Ziyaettin Ozbilen( Book )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

"The energy carrier hydrogen is expected to solve some energy challenges. Since its oxidation does not emit greenhouse gases (GHGs), its use does not contribute to climate change, provided that it is derived from clean energy sources. Thermochemical water splitting using a Cu-Cl cycle, linked with a nuclear super-critical water cooled reactor (SCWR), which is being considered as a Generation IV nuclear reactor, is a promising option for hydrogen production. In this thesis, a comparative environmental study is reported of the three-, four- and five-step Cu-Cl thermochemical water splitting cycles with various other hydrogen production methods. The investigation uses life cycle assessment (LCA), which is an analytical tool to identify and quantify environmentally critical phases during the life cycle of a system or a product and/or to evaluate and decrease the overall environmental impact of the system or product. The LCA results for the hydrogen production processes indicate that the four-step Cu-Cl cycle has lower environmental impacts than the three- and five-step Cu-Cl cycles due to its lower thermal energy requirement. Parametric studies show that acidification potentials (APs) and global warming potentials (GWPs) for the four-step Cu-Cl cycle can be reduced from 0.0031 to 0.0028 kg SO2-eq and from 0.63 to 0.55 kg CO2-eq, respectively, if the lifetime of the system increases from 10 to 100 years. Moreover, the comparative study shows that the nuclear-based S-I and the four-step Cu-Cl cycles are the most environmentally benign hydrogen production methods in terms of AP and GWP. GWPs of the S-I and the four-step Cu-Cl cycles are 0.412 and 0.559 kg CO2-eq for reference case which has a lifetime of 60 years. Also, the corresponding APs of these cycles are 0.00241 and 0.00284 kg SO2-eq. It is also found that an increase in hydrogen plant efficiency from 0.36 to 0.65 decreases the GWP from 0.902 to 0.412 kg CO2-eq and the AP from 0.00459 to 0.00209 kg SO2-eq for the four-step Cu-Cl cycle."
Design and optimization of a three-fingered robot hand by Nasim Jafargholibeik( Book )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

"Humanoid robots have proven to be very useful and could revolutionize the way humans live. Knowing human anatomy and behaviour helps improve a robotic mechanisms ability to perform human tasks. The following thesis introduces the concept of a threefingered robot hand and its driving mechanism. The hand includes two fingers and a thumb. Using the concept of "an under actuated system", each finger consists of three revolute joints which are driven by two actuators and tooth belt transmission system. The thumb has two joints but only one joint is active and actuated by one motor. The passive joint is designed to set the initial position of the thumb on the piano key if necessary. Required angle of rotation for each joint has been calculated through Inverse Kinematics. Once the fingertip presses the piano key, it should apply 1N force to play a note. Force Sensing Resistors at each finger tip, as a control method, are introduced to the system to accurately measure the amount of applied force from the finger tip on the key and increase the angle of rotation of the motor if needed. Stress and deformation of the joints have been studied through Finite Element Analysis. A prototype model, consisting of a single finger was built to better understanding the functionality of the concept. Analysis of this model, led to necessary modification of the transmission system and some design revisions to each link. Genetic Algorithm using MATLAB was used to optimize the performance Index of a finger. Finally the hand assembly including all the components and driving mechanism was constructed and experimented in the playing mode."
Development and optimization of new generation start-up instrumentation systems (SUI) for domestic CANDU reactors by Elnara Nasimi( Book )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

"Due to the age and operating experience of Bruce Power units, equipment ageing and obsolescence has become one of the main challenges that need to be resolved for all systems, structures and components in order to ensure a safe and reliable production of energy. The research objectives of this thesis will focus on methodology for modernization of Start- Up Instrumentation (SUI), both in-core and Control Room equipment, using a new generation of detectors and cables in order to manage obsolescence. The main objective of this thesis is to develop a new systematic approach to SUI installation/replacement procedure development and optimization. Although some additional features, such as real-time data monitoring and storage/archiving solutions for SUI systems are also examined to take full advantage of today?s digital technology, the objective of this thesis does not include detailed parametrical studies of detector or system performance. Instead, a number of technological, operational and maintenance issues associated with Start-Up Instrumentation systems at Bruce Power will be identified in this project and a structured approach to developing a replacement/installation procedure that can be standardized and used across all of the domestic CANDU stations is proposed. Finally, benefits of Hierarchical Control Chart (HCC) methodology for all stages of plant life management, such as system design, development, operation and maintenance are demonstrated. Keywords: Task Breakdown and Analysis methodology, installation/removal procedure development and optimization, risk-based analysis and optimization, Hierarchical Control Chart (HCC) methodology for system maintenance and troubleshooting, Start-Up Instrumentation (SUI), Ion Chambers, Fission Chambers, proportional counters, Shutdown System 1 (SDS1), Shutdown System 2 (SDS2)."
Investigation of sustainable hydrogen production from steam biomass gasification by Abdussalam Goma Abuadala( Book )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

"Hydrogen is a by-product of the gasification process and it is environmentally friendly with respect to pollution and emission issues when it is derived from a CO2-neutral resource such as biomass. It is an energy carrier fuel and has flexibility to convert efficiently to other energy forms to be used in different energy applications like fuel cells. The proposed research presents literature on previous gasification studies regarding hydrogen production from biomass and updates the obtained results. The main objectives of the thesis are: a) to study hydrogen production via steam biomass (sawdust) gasification; b) to evaluate the produced hydrogen by performing comprehensive analysis by using thermodynamic, exergoeconomic and optimization analyses. Despite details specific to the gasifier, in general, there is a special need to theoretically address the gasifier that gasifies biomass to produce hydrogen. This further study of gasification aspects presents a comprehensive performance assessment through energy and exergy analyses, provides results of the optimization studies on minimizing hydrogen production costs, and provides a thermo-economic analysis for the proposed systems (Systems I, II and III). This thesis also includes the results from the performed study that aims to investigate theoretical hydrogen production from biomass (sawdust) via gasification technology. Results from the performed parametric study show that the gasification ratio increases from 70 to 107 gH2 per kg of sawdust. In the gasification temperature studied, system II has the highest energy efficiency that considers electricity production where it increases from 72 % to 82 % and has the lowest energy efficiency that considers hydrogen yield where it increases from 45 % to 55 %. Also, it has the lowest hydrogen cost of 0.103 $/kW-h. The optimization results show that the optimum gasification temperatures for System I, System II and System III are 1139 K, 1245 K and 1205 K, respectively."
Social-based trustworthy data forwarding in vehicular delay tolerant networks by Abdulelah Alganas( Book )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

"Vehicular ad hoc network (VANET) is an emerging new communication technol-ogy which has attracted a lot of research attention from academic community and indus-try. For many applications in VANETs, information has to be transmitted through mul-tiple hops before it reaches its destination that makes it a subject to various security at-tacks and privacy breaches. Thus, security and privacy issues could limit its adaption by the public community. In this study, we propose and evaluate social based trustworthy data forwarding scheme for VANET. First, by using social network analysis techniques, we provide a framework to strategically deploy Road-Side Units (RSUs) infrastructure in order to im-prove reliability, efficiency, and high packet delivery for VANET. It is based on multiple social centrality assessments of street network which help in placing RSUs at high social intersections. This social placement of RSUs will dramatically improve data dissemina-tion as the opportunity of contacting vehicles increase while costs of RSU deployment can be kept under control. Second, we propose a secure and privacy-preserving message forwarding protocol, which utilizes RSUs to forward messages between vehicles. The protocol takes advantage of high performance capability of RSUs to store and forward messages to their destinations, where these RSUs utilize re-encryption technique to form a mix network to provide adequate privacy for senders and receivers. Then detailed anal-ysis in terms of security, message overhead, delivery ratio, and average delay are per-formed to evaluate the efficiency and effectiveness of our proposed scheme. Lastly, we tackled the security and privacy challenges existing in social-aware data diffusion by proposing an efficient vehicle social evaluation (EVSE) scheme. Our scheme enables each vehicle to show its authentic social evaluation to others while not disclosing its past location information. As a result, it can meet the prerequisites for the success of social aware data diffusion in VANETs."
Novel opposition-based sampling methods for efficiently solving challenging optimization problems by Ali Esmailzadeh( Book )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

"In solving noise-free and noisy optimization problems, candidate initialization and sampling play a key role, but are not deeply investigated. It is of interest to know if the entire search space has the same quality for candidate-solutions during solving different type of optimization problems. In this thesis, a comprehensive investigation is conducted in order to clear those doubts, and to examine the effects of variant sampling methods on solving challenging optimization problems, such as large-scale, noisy, and multi-modal problems. As a result, the search space is segmented by using seven segmentation schemes, namely: Center-Point, Center-Based, Modula-Opposite, Quasi-Opposite, Quasi-Reflection, Supper- Opposite, and Opposite-Random. The introduced schemes are studied using Monte-Carlo simulation, on various types of noise-free optimization problems, and ultimately ranked based on their performance in terms of probability of closeness, average distance to unknown solution, number of solutions found, and diversity. Based on the results of the experiments, high-ranked schemes are selected and utilized on well-known metaheuristic algorithms, as case studies. Two categories of case studies are targeted; one for a singlesolution- based metaheuristic (S-metaheuristic) and another one for a population based metaheuristic (P-metaheuristic). A high-ranked single-solution-based scheme is utilized to accelerate Simulated Annealing (SA) algorithm, as a noise-free S-metaheuristic case study. Similarly, for noise-free P-metaheuristic case study, an effective population-based algorithm, Differential Evolution (DE), has been utilized. The experiments confirm that the new algorithms outperform the parent algorithm (DE) on large-scale problems. In the same direction, with regards to solving noisy problems more efficiently, a Shaking-based sampling method is introduced, in which the original noise is tackled by adding an additional noise into the search process. As a case study, the Shaking-based sampling is utilized on the DE algorithm, from which two variant algorithms have been developed and showed impressive performance in comparison to the classical DE, in tackling noisy largescale problems. This thesis has created an opportunity for a comprehensive investigation on search space segmentation schemes and proposed new sampling methods. The current study has provided a guide to use appropriate sampling schemes for a given types of problems such as noisy, large-scale and multi-modal optimization problems. Furthermore, this thesis questions the effectiveness of uniform-random sampling method, which is widely used in of S-Metaheuristic and P-Metaheuristic algorithms."
Data hiding and detection in Office Open XML (OOXML) documents by Mohammad Ali Raffay( Book )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

"With the rapid development and popularity of information technology, criminals and mischievous computer users are given avenues to commit crimes and malicious activities. One of the commonly used tactics, called steganography, is to hide information under a cover media so that except participants, no one else knows the existence of such information. Many techniques have been proposed for hiding data in images, videos and audios, but there is not much research devoted to data hiding in the popular MS Office documents which have recently adopted Office Open XML (OOXML) format. In this research, we first focus on identifying several data hiding techniques for OOXML documents. Then, we design and develop a fast detection algorithm based on the unique internal structure of OOXML documents, which contains multiple XML files, by using multi-XML query technique. Experimental results show the proposed detection algorithm outperforms the traditional one in terms of detection speed and completeness, where performance is the key to success of detecting hidden data in OOXML documents due to the fact that millions of documents are generated and transferred over the internet every day."
Secure and compromise-resilient architecture for advanced metering infrastructure by Khalid Alfaheid( Book )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

"In recent years, the Smart Grid has grown to be the solution for future electrical energy that promises to avoid blackouts as well as to be energy efficient, environmentally and customer-friendly. In Smart Grid, the customer-friendly applications are a key element that provides the feature for recognizing the active expenditure of current energy via an Advanced Metering Infrastructure (AMI) subsystem. In fact, the smart meter, as a major part of AMI that is installed in residences, which provides more details about a consumer"s usage. The smart meter measures hour-by-hour usage of a house, and then instantly transmits the record to the utility via two-way communications, unlike the previous electrical system that collects all usage monthly. However, the live measurement of the usage creates a potential privacy leak since each electrical usage records the behaviour of consumers in the home. Therefore, any communication channel between customers and utility should have some sort of confidentiality which protects consumer privacy. In reality, smart meters are generally located in an insecure area of the house (outside), therefore anyone can potentially tamper with the device, noting the fact that it is low-end device. As a result, there is a great possibility of compromising the smart meter, resulting in disclosure of consumer usage. Actually, the nature of a smart meter, and the cost constraints, create a challenge to secure the network. Therefore, the dual motivating problems are the protection of consumer privacy as well as achieving cost efficiency. In this research, we propose a new secure and compromise resilient architecture that continues two major components: a smart meters compromise attack detection scheme and a secure usage reporting protocol. Firstly, the smart meters compromise attack detection scheme improves the security of the smart meter, preventing an adversary from compromising the smart meter. Secondly, the secure usage reporting protocol improves the security of communication between the smart meter and the utility, preventing an adversary from identifying each household's usage reported by smart meters."
