Show moreNetwork Function Virtualization (NFV) is an emerging technology that transforms legacy hardware-based network infrastructure into software-based virtualized networks. Instead of using dedicated hardware and network equipment, NFV relies on cloud and virtualization technologies to deliver network services to its users. These virtualized network services are considered better solutions than hardware-based network functions because their resources can be dynamically increased upon the consumer’s request. While their usefulness can’t be denied, they also have some security implications. In complex systems like NFV, the threats can come from a variety of domains due to it containing both the hardware and the virtualize entities in its infrastructure. Also, since it relies on software, the network service in NFV can be manipulated by external entities like third-party providers or consumers. This leads the NFV to have a larger attack surface than the traditional network infrastructure. In addition to its own threats, NFV also inherits security threats from its underlying cloud infrastructure. Therefore, to design a secure NFV system and utilize its full potential, we must have a good understanding of its underlying architecture and its possible security threats. Up until now, only imprecise models of this architecture existed. We try to improve this situation by using architectural modeling to describe and analyze the threats to NFV. Architectural modeling using Patterns and Reference Architectures (RAs) applies abstraction, which helps to reduce the complexity of NFV systems by defining their components at their highest level. The literature lacks attempts to implement this approach to analyze NFV threats. We started by enumerating the possible threats that may jeopardize the NFV system. Then, we performed an analysis of the threats to identify the possible misuses that could be performed from them. These threats are realized in the form of misuse patterns that show how an attack is performed from the point of view of attackers. Some of the most important threats are privilege escalation, virtual machine escape, and distributed denial-of-service. We used a reference architecture of NFV to determine where to add security mechanisms in order to mitigate the identified threats. This produces our ultimate goal, which is building a security reference architecture for NFV.

Show more“Tomorrow is Saint Valentine’s Day” is a manic line of dialogue spoken by Ophelia in Shakespeare’s Hamlet. I have chosen that line as the title of my thesis and exhibition. Much of my graduate work has emanated from scenes in Shakespeare’s plays. I make dimensional paintings, prints, and sculptures that leverage a wide variety of media, material, and processes. I have chosen the intense drama of Ophelia’s final appearance on stage to inspire this body of work. The drama and imagery of Shakespeare’s plays has been a profound source of ideas for me. They motivate me to connect with all available resources in an energetic way to create visually captivating pieces of art. My objective is not to illustrate any given scene but to leverage the text for a personal artistic experience. The result is an abstraction that captures the energy of a dramatic moment. The art I produce is an expressive record of my relationship with the literature.

Because of this disconnect, there exists a need for a portal to find Who’s Who in Engineering Education in the Americas. The objective of this thesis is to built an object-oriented architecture for this proposed portal. The Unified Modeling Language (UML) model developed in this thesis incorporates the basic structure of a social network for academic purposes. Reverse engineering of three social networks portals yielded important aspects of their structures that have been incorporated in the proposed UML model. Furthermore, the present work includes a pattern for academic social networks.

Show moreSilenced for almost half a century, testimonies of those who lost the Spanish Civil War are now surfacing and being published. The origin of this dissertation was the chance discovery that Martín Herrera de Mendoza, a Spanish Civil War exile living in the United States, was truly a Catalonian anarchist named Antonio Vidal Arabí. This double identity was a cover for the political activist dedicated to the fight for change in the anarchist workers’ union CNT (National Confederation of Workers) and the FAI (Federation of Iberian Anarchists). He founded the FAI chapter in Santa Cruz de Tenerife and planned a failed assassination attempt on General Franco’s life in an effort to avoid the military takeover in 1936. This dissertation is the reconstruction of Antonio Vidal Arabí’s life narrative. It is based on the texts written during his seventeen-month stay as a refugee in Great Britain. Copies of his writings were left in a suitcase with a fellow anarchist who he instructed to have sent to his family upon his death. In 1989, “The English Suitcase” was delivered to his children in Barcelona. Based on his own account, this study follows his service as an intelligence agent for the Spanish Republic during the War. When it was over, he attempted to evacuate his family from France, to save them from the threat of the Nazi invasion and reunite with them in England or America. The analysis of the letters he wrote to his wife and children in France documents how he hid from Franco’s spies using his dual identity. In his letters, always signed as Martín Herrera de Mendoza, he invents a persona in order to help his family. The present study narrates his transformation into the persona he created and the events that brought about his translation into his “other.” Antonio Vidal Arabí’s bilinguism and biculturality is underlined as the main factors in his change into Martín Herrera de Mendoza. His was a voyage into exile documented by his own words; a story of survival and reinvention.

Show moreIn the field of machine prognostics, vibration analysis is a proven method for detecting and diagnosing bearing faults in rotating machines. One popular method for interpreting vibration signals is envelope demodulation, which allows a technician to clearly identify an impulsive fault source and its severity. However incipient faults -faults in early stages - are masked by in-band noise, which can make the associated impulses difficult to detect and interpret. In this thesis, Wavelet De-Noising (WDN) is implemented after envelope-demodulation to improve accuracy of bearing fault diagnostics. This contrasts the typical approach of de-noising as a preprocessing step. When manually measuring time-domain impulse amplitudes, the algorithm shows varying improvements in Signal-to-Noise Ratio (SNR) relative to background vibrational noise. A frequency-domain measure of SNR agrees with this result.

Now, as the technological advancements made in new media lead us to this point, there is the need to reconcile the connection of the narrative with that of new media. Many theorists such as Manovich believe the narrative is slowly dying as new media continues to evolve. While others such as Bolter and Grusin think the story and traditional media is merely reinserting itself into new media. In the augmented reality story, The Seven Ages of Susanna, I seek to create a marriage of conventional media narrative and illustration techniques. By using new media tools of Vuforia and Unity, I aim to create an immersive experience that reconciles this issue.

Show moreA fundamental question in Complexity Science is how numerous dynamic processes coordinate with each other on multiple levels of description to form a complex whole - a multiscale coordinative structure (e.g. a community of interacting people, organs, cells, molecules etc.). This dissertation includes a series of empirical, theoretical and methodological studies of rhythmic coordination between multiple agents to uncover dynamic principles underlying multiscale coordinative structures. First, a new experimental paradigm was developed for studying coordination at multiple levels of description in intermediate-sized (N = 8) ensembles of humans. Based on this paradigm, coordination dynamics in 15 ensembles was examined experimentally, where the diversity of subjects movement frequency was manipulated to induce di erent grouping behavior. Phase coordination between subjects was found to be metastable with inphase and antiphase tendencies. Higher frequency diversity led to segregation between frequency groups, reduced intragroup coordination, and dispersion of dyadic phase relations (i.e. relations at di erent levels of description). Subsequently, a model was developed, successfully capturing these observations. The model reconciles the Kuramoto and the extended Haken-Kelso-Bunz model (for large- and small-scale coordination respectively) by adding the second-order coupling from the latter to the former. The second order coupling is indispensable in capturing experimental observations and connects behavioral complexity (i.e. multistability) of coordinative structures across scales. Both the experimental and theoretical studies revealed multiagent metastable coordination as a powerful mechanism for generating complex spatiotemporal patterns. Coexistence of multiple phase relations gives rise to many topologically distinct metastable patterns with di erent degrees of complexity. Finally, a new data-analytic tool was developed to quantify complex metastable patterns based on their topological features. The recurrence of topological features revealed important structures and transitions in high-dimensional dynamic patterns that eluded its non-topological counterparts. Taken together, the work has paved the way for a deeper understanding of multiscale coordinative structures.

Show moreThis thesis identifies the price inconstancies between male and female consumer personal care products, such as razors and deodorants. Economic research suggests consumers purchase products based on their willingness to pay, which depends upon satisfaction granted from the product. If this is true, the question must be asked: what grants these consumers high satisfaction from product purchasing? To answer this question, this thesis investigates the rhetorical effect that stems from product design. Using a rhetorical criticism technique, I analyze how product design allows consumers to project their gender identity. I assert that consumers are interpellated to choose products based on their gender. Once this interpellation takes place, a constitutive rhetoric formed by the product’s design already assumes the consumer’s wants by embedding masculine or feminine ideologies. The analysis shows product design perpetuates clear gender dichotomy and fortifies the belief of gender binaries.

A content analysis of five television programs (Black-ish, Dear White People, Empire, Grown-ish, and The Carmichael Show) were analyzed. Through the analysis, darker complexion women were analyzed and it was found negative attributes were used to describe them in terms of beauty, and for lighter skinned females positives attributes were used throughout the show. In the five episodes examined that aired in the 21st century, beauty was defined based on one’s complexion as it was before in previous centuries. Issues of colorism are still displayed in 21st century television shows and through positive and negative caricatures. Colorism has a direct impact on how women of color are perceived and it can directly impact their self-esteem.

Show moreWithin the Caribbean, the islands of Guadeloupe and Martinique are unusual: they are French overseas departments and thus also European Union members. As such, they must assimilate to French national culture even though their heterogeneous populations, mainly descendants of exploited imported labour, have their own unique island identity. Their heavy economic dependence on France and the effects of modernization and globalization pose further identitarian challenges for them. Franco-Antillean literature clearly reflects this long-standing identity confusion. This thesis explores two very recent novels— Toxic Island by Guadeloupean Ernest Pépin and L’Empreinte à Crusoé by Martinican Patrick Chamoiseau— and their divergent stylistic treatments of individuation. Both are inspired by Édouard Glissant’s theories of Relation and Tout- Monde; both engage questions of language, orality, the island space, race, the subject of alterity and the role of the arts and artists in identity formation. Yet both are also marked by distinctly unique forms of ambivalence.

The major performance parameters are delay time and the average number of active processors, called processing power. The bus arbitration methods are described using state and timing diagrams. Multiprocessor systems using these methods of arbitration are then modeled using Markov chains to enable the formulation of processing power. From processing power other performance parameters can be derived. A comparison is then made among the two bus arbitration methods based on the analytical results where processors access the bus at an equal rate. Simulations of multiprocessor systems using either of the two arbitration methods were performed to validate the analytical models for equal bus request rates. Simulations are also performed of a system of processors using the main bus at unequal rates.

Show moreIn recent years, many protocols for efficient Multicasting have been proposed. However, many of the Internet Service Providers (ISPs) are reluctant to use multicastenabled routers in their networks. To provide such incentives, new protocols are needed to improve the quality of their services. The challenge is to find a compromise between allocating Bandwidth (BW) among different flows in a fair manner, and favoring multicast sessions over unicast sessions. In addition, the overall higher level of receiver satisfaction should be achieved. In this dissertation, we propose three new innovative protocols to favor multicast sessions over unicast sessions. Multicast Favored BW Allocation- Logarithmic (MFBA-Log) and Multicast Favored BW Allocation-Linear (MFBALin) protocols allocate BW proportional to the number of down stream receivers. The proposed Multicast Reserved BW Allocation (MRBA) protocol allocates part of the BW in the links only to multicast sessions. Simulation results show the increase in the overall level of Receiver Satisfaction in the network.

This dissertation presents a novel hybrid MANET routing protocol, Adaptive On-demand MANET Routing (AOMAR) protocol. AOMAR borrowed the concepts of temporal location updates in operating systems and cache memories to reconstruct broken routes. Each route entry in a mobile host will have a reference field that is set to indicate whether the route is used within a certain period of time called refresh time. Using the refresh time parameter and the route reference field, AOMAR behavior can be controlled to behave as pure On-demand, Adaptive, or history related Proactive protocol. The three versions of AOMAR, On-demand, Adaptive and Proactive, have been simulated using different network sizes, loads and mobility patterns. Three performance metrics---throughput, delay and overhead---are collected. The results show that AOMAR on-demand has the same pattern of results when compared with other exiting on-demand protocols. On-demand AOMAR shows better performance when compared to Adaptive AOMAR for simulation sessions with uniform workloads. On the other hand Adaptive AOMAR outperforms On-demand AOMAR for simulation sessions with non-uniform workloads. Proactive AOMAR reconstructs recently used routes that have broken. Therefore, its routing overhead results change with the change of the network loads and mobility rates. This is not the case for traditional proactive protocols. Proactive AOMAR has lower control overhead and saves the bandwidth when compared with traditional existing proactive routing protocols. In addition to developing and simulating AOMAR, a new mobility model is proposed. Synchronized Random Direction Model of Motion with Constant Speed (SRDMCS) is a model that is suitable to emulate objects that move in random directions with a constant speed and within a certain area of movement. A new formula, Movement Related Update (MRU), is proposed and implemented. In MRU, the refresh period parameter value is linked to the network mobility level. Using MRU in the simulation gives AOMAR a third dimension such that the protocol not only adapts with how frequently the routes are used and how frequently they are broken, but also with how dynamic the network is.

Show moreThe road traffic along with other key infrastructure sectors such as telecommunication, power, etc. has an important role in economic and technological growth of one country. Traffic engineers and analysts are responsible for solving a diversity of traffic problems, such as traffic data acquisition and evaluation. In response to the need to improve traffic operation, researchers implement advanced technologies and integration of systems and data, and develop state-of-the-art applications. This thesis introduces three novel web applications with an aim to offer traffic operators, managers, and analysts’ possibility to monitor the congestion, and analyze incidents and signal performance measures. They offer more detailed analysis providing users with insights from different levels and perspectives. The benefit of providing these visualization tools is more efficient estimation of the performance of local networks, thus facilitating the decision making process in case of emergency events.

This study examines the representation of women in Emile Zola’s famous series Les Rougon-Macquart. Critics have described Zola’s novels and their presentation of women as misogynist, yet this judgment obscures many of the textual details establishing the female protagonists’ relationships to industrial capitalism and the rapidly changing social landscape in late nineteenth century France.

Show moreThis study examines the representation of women in Emile Zola’s famous series Les Rougon-Macquart. Critics have described Zola’s novels and their presentation of women as misogynist, yet this judgment obscures many of the textual details establishing the female protagonists’ relationships to industrial capitalism and the rapidly changing social landscape in late nineteenth century France. This study reexamines the narrative synthesis between Zola’s naturalist “objective” narrator and his female protagonists. It also highlights one particular pairing that of Adelaide Fouque and her opportunist daughter-in-law, Felicité Puch: Whereas Adelaide, the biological matriarch of the family who figures in each of the twenty novels, does not have an active voice, Felicité as maternal protectrice of the family speaks frankly, even aggressively. Zola uses this pairing to link one generation to the next, a key structural element of his naturalist project. Ultimately, Zola’s representation of women is more complex than might otherwise be understood.

Show moreThis study is a focused effort on elucidating the performance aspects of modern, handheld wireless devices and associated mobile network services. Specifically addressed thereof are: (i) Assessing the performance details on certain hardware sections of smart handheld devices and (ii) determining the performance profile of market penetration considerations vis-à-vis provisioning mobile networks. To meet the scope of this research, the projected efforts are exercised in compiling relevant literature and deciding the said hardware and technoeconomic performance issues. Hence, written in two parts, Part A is devoted to hardware performance details of smart, handheld devices relevant to (a) delay issues in PCB layouts; (b) crosstalk problems at the baseband level (audio/multimedia) using EMI concepts and (c) ascertaining non-catastrophic EMP/EMI effects at the RF-sections so as to implement protection strategies via compensating networks. Part B is concerned with the technoeconomics of wireless networks in supporting mobile (handheld devices). Correspondingly, two market related considerations versus service performance details are considered. The first one refers to deducing a relative performance index that includes technology (mobile speed) details plus economics profiles of the users in the service area. The second task refers to elucidating a performance index of such services in terms of hedonic pricing heuristics. The theoretical aspects of the test studies as above are supplemented with experimental and/or simulation details as appropriate. Hence, the efficacy of performance details are discussed in real-world applications. Lastly, possible research items for future studies are identified as open-questions.
