description: © 2018 by the authors. Licensee MDPI, Basel, Switzerland. Background: Pediatricians following clinical practice guidelines for tobacco intervention (“Ask, Advise, and Refer” [AAR]) can motivate parents to reduce child tobacco smoke exposure (TSE). However, brief clinic interventions are unable to provide the more intensive, evidence-based behavioral treatments that facilitate the knowledge, skills, and confidence that parents need to both reduce child TSE and quit smoking. We hypothesized that a multilevel treatment model integrating pediatric clinic-level AAR with individual-level, telephone counseling would promote greater long-term (12-month) child TSE reduction and parent smoking cessation than clinic-level AAR alone. Methods: Pediatricians were trained to implement AAR with parents during clinic visits and reminded via prompts embedded in electronic health records. Following AAR, parents were randomized to intervention (AAR + counseling) or nutrition education attention control (AAR + control). Child TSE and parent quit status were bioverified. Results: Participants (n = 327) were 83% female, 83% African American, and 79% below the poverty level. Child TSE (urine cotinine) declined significantly in both conditions from baseline to 12 months (p = 0.001), with no between-group differences. The intervention had a statistically significant effect on 12-month bioverified quit status (p = 0.029): those in the intervention group were 2.47 times more likely to quit smoking than those in the control. Child age was negatively associated with 12-month log-cotinine (p = 0.01), whereas nicotine dependence was positively associated with 12-month log-cotinine levels (p = 0.001) and negatively associated with bioverified quit status (p = 0.006). Conclusions: Pediatrician advice alone may be sufficient to increase parent protections of children from TSE. Integrating clinic-level intervention with more intensive individual-level smoking intervention is necessary to promote parent cessation.

description: Various disorders closely linked to gut dysbiosis have been associated with poor dietary patterns. Dietary prebiotic fibers play an essential role in modulating the gut microbiome by enhancing the abundance of beneficial microorganisms and improving the production of short-chain fatty acids. Arabinoxylan (AX) is a major component of most dietary fibers and has been shown to exhibit potential prebiotic properties and modulate gut microbiome composition. This study aimed to investigate the in vitro impact of bioengineered wheat arabinoxylan on depression-inversely linked gut microbes and human gut microbiome diversity and metabolism. This study demonstrates the ability of bioengineered AX to stimulate the growth of depression-inversely linked gut bacterial species (Faecalibacterium prausnitzii and Lacticaseibacillus rhamnosus LGG). On the microbiome composition, the bioengineered AX induced an increased abundance of beneficial bacterial taxa (Bacteroides, Bifidobacterium, Anaerofustis, and Eubacterium) compared to the control and native AX. These effects on microbes translated into significant metabolic activity and produced primary SCFAs (acetate, butyrate, and propionate). The findings from this study suggest that bioengineered wheat arabinoxylan could be considered a promising strategy for fostering next-generation prebiotics targeting depression-inversely linked gut microbes and also supports the structure-function relationship between AX and the human gut microbiome.

description: We investigate the properties of the nonequilibrium steady state for the stochastic system driven by a nonlinear drift force and influenced by noises which are not identically and independently distributed. The nonequilibrium steady state (NESS) current results from a residual part of the drift force which is not cancelled by the diffusive action of noises. From our previous study for the linear drift force the NESS current was found to circulate on the equiprobability surface with the maximum at a stable fixed point of the drift force. For the nonlinear drift force, we use the perturbation theory with respect to the cubic and quartic coefficients of the drift force. We find an interesting potential landscape picture where the probability maximum shifts from the fixed point of the drift force and, furthermore, the NESS current has a nontrivial circulation which flows off the equiprobability surface and has various centers not located at the probability maximum. The theoretical result is well confirmed by the computer simulation.

description: We study the semigroup C*-algebra of a positive cone P of a weakly quasi-lattice ordered group. That is, P is a subsemigroup of a discrete group G with P\cap P^{-1}=\{e\} and such that any two elements of P with a common upper bound in P also have a least upper bound. We find sufficient conditions for the semigroup C*-algebra of P to be nuclear. These conditions involve the idea of a generalised length function, called a "controlled map", into an amenable group. Here we give a new definition of a controlled map and discuss examples from different sources. We apply our main result to establish nuclearity for semigroup C*-algebras of a class of one-relator semigroups, motivated by a recent work of Li, Omland and Spielberg. This includes all the Baumslag--Solitar semigroups. We also analyse semidirect products of weakly quasi-lattice ordered groups and use our theorem in examples to prove nuclearity of the semigroup C*-algebra. Moreover, we prove that the graph product of weak quasi-lattices is again a weak quasi-lattice, and show that the corresponding semigroup C*-algebra is nuclear when the underlying groups are amenable.

description: Low Temperature Oxidation (LTO) reactions are known to modify the composition and properties of crude oils during air injection process such as In Situ Combustion/High Pressure Air Injection. What is less understood is the effect of these reactions when residual oxygen is present in a CO2 stream that is injected into a light oil reservoir during an EOR/CO2 sequestration process. The objective of this study is to examine the compositional changes of a sample of Swan Hills light oil due to low temperature oxidation reactions during CO2 flooding. The experimental data were generated by Jia (2007), in which CO2 was injected into Swan Hills light oil with oxygen as an impurity. The experiments were performed in batch reactors under different temperatures, initial pressures, oxygen concentrations in CO2, and times. Kinetic model development for light oil in this research is based on Jia’s Athabasca bitumen LTO model. The model proposed in this thesis involves phase behavior and mass transfer process during the mixing of the injected fluid and the light oil. Oxygen addition and oxygen induced cracking reactions were assumed to happen in the hydrocarbon rich phase with combustion reactions occurring in both the hydrocarbon rich and CO2 rich phases. This model describes detailed kinetic mechanisms and concentration changes of individual pseudo-components during the LTO reactions. To simplify the calculation process, the hydrocarbon is characterized in terms of maltenes, asphaltenes and coke. The model results show that for light oil LTO reactions, phase behavior plays an important role. The asphaltenes product may restrict oxygen from transferring from one phase to another at low temperatures. Five reactions were proposed and the kinetic parameters were optimized to meet satisfactory results.

description: © 2018 The Authors We extend the improved Collins–Soper–Sterman (iCSS) W+Y construction recently presented in [1] to the case of polarized observables, where we focus in particular on the Sivers effect in semi-inclusive deep-inelastic scattering. We further show how one recovers the expected leading-order collinear twist-3 result from a (weighted) qT-integral of the differential cross section. We are also able to demonstrate the validity of the well-known relation between the (TMD) Sivers function and the (collinear twist-3) Qiu–Sterman function within the iCSS framework. This relation allows for their interpretation as functions yielding the average transverse momentum of unpolarized quarks in a transversely polarized spin-[Formula presented] target. We further outline how this study can be generalized to other polarized quantities.

description: The acquisition of precise and reliable nuclear data is a prerequisite to success for stellar evolution and nucleosynthesis studies. Core-collapse simulators find it challenging to generate an explosion from the collapse of the core of massive stars. It is believed that a better understanding of the microphysics of core-collapse can lead to successful results. The weak interaction processes are able to trigger the collapse and control the lepton-to-baryon ratio ($Y_{e}$) of the core material. It is suggested that the temporal variation of $Y_{e}$ within the core of a massive star has a pivotal role to play in the stellar evolution and a fine-tuning of this parameter at various stages of presupernova evolution is the key to generate an explosion. During the presupernova evolution of massive stars, isotopes of iron, mainly $^{54,55,56}$Fe, are considered to be key players in controlling $Y_{e}$ ratio via electron capture on these nuclide. Recently an improved microscopic calculation of weak interaction mediated rates for iron isotopes was introduced using the proton-neutron quasiparticle random phase approximation (pn-QRPA) theory. The pn-QRPA theory allows a microscopic \textit{state-by-state} calculation of stellar capture rates which greatly increases the reliability of calculated rates. The results were suggestive of some fine-tuning of the $Y_{e}$ ratio during various phases of stellar evolution. Here we present for the first time the fine-grid calculation of the electron and positron capture rates on $^{54,55,56}$Fe. Core-collapse simulators may find this calculation suitable for interpolation purposes and for necessary incorporation in the stellar evolution codes.

description: The objective of this study was to explore facilitators and barriers to chronic disease management programs and resources among Calgarian sub-Saharan African (SSA) immigrants with cardiovascular disease (CVD)/ related risk factors (i.e. hypertension, diabetes, and hypercholesterolemia). Utilizing mixed methods design, descriptive statistics from a survey assessing CVD management practices and service use was collected, among a sample of adult SSA immigrants in Calgary. Participants with related risk factors were selected for interviews on barriers to self-health management. Participants with CVD-related conditions accessed health care services through primary access points; mostly family doctors (n=68, 88.31%). Participants over 40 years with CVD-related conditions reported highest management difficulties (n=26, 25.49%). Thematic analysis showed, low morbidity and good healthcare provider relationships, were facilitators to successful CVD-related disease management; whereas, high morbidity and work stress were barriers. Differences in age and morbidity appear to influence CVD testing and health management styles for this sample.

description: Starting from a recent model of the eta'N interaction, we evaluate the eta'-nucleus optical potential, including the contribution of lowest order in density, t rho/2m_eta', together with the second order terms accounting for eta' absorption by two nucleons. We also calculate the formation cross section of the eta' bound states from (pi+,p) reactions on nuclei. The eta'-nucleus potential suffers from uncertainties tied to the poorly known eta'N interaction, which can be partially constrained by the experimental modulus of the eta'N scattering length and/or the recently measured transparency ratios in eta' nuclear photoproduction. Assuming an attractive interaction and taking the claimed experimental value |a_eta'N| = 0.1 fm, we obtain a eta' optical potential in nuclear matter at saturation density of V_eta' = -(8.7 + 1.8i) MeV, not attractive enough to produce eta' bound states in light nuclei. Larger values of the scattering length give rise to deeper optical potentials, with moderate enough imaginary parts. For a value |a_eta'| = 0.3 fm, which can still be considered to lie within the uncertainties of the experimental constraints, the spectra of light and medium nuclei show clear structures associated to eta'-nuclear bound states and to threshold enhancements in the unbound region.

description: © 2018 John Wiley & Sons, Ltd. Fog computing, a non-trivial extension of cloud computing to the edge of the network, has great advantage in providing services with a lower latency. In smart grid, the application of fog computing can greatly facilitate the collection of consumer's fine-grained energy consumption data, which can then be used to draw the load curve and develop a plan or model for power generation. However, such data may also reveal customer's daily activities. Non-intrusive load monitoring (NILM) can monitor an electrical circuit that powers a number of appliances switching on and off independently. If an adversary analyzes the meter readings together with the data measured by an NILM device, the customer's privacy will be disclosed. In this paper, we propose an effective privacy-preserving scheme for electric load monitoring, which can guarantee differential privacy of data disclosure in smart grid. In the proposed scheme, an energy consumption behavior model based on Factorial Hidden Markov Model (FHMM) is established. In addition, noise is added to the behavior parameter, which is different from the traditional methods that usually add noise to the energy consumption data. The analysis shows that the proposed scheme can get a better trade-off between utility and privacy compared with other popular methods.

The utterance of our names : the practice and the person in vocal work

Publisher: name: University of British Columbia

description: The author’s intention in undertaking a Master of Fine Arts degree in Theatre was to gain a deeper understanding of vocal training for actors and to investigate the methodologies of a number of master voice teachers. Her program of study undertaken within the Department of Theatre and Film had a voice specialization. The learning framework included graduate courses in directing, assisting Gayle Murphy in voice classes and Neil Freeman in Shakespeare text classes in the Bachelor of Fine Arts Acting program at the University of British Columbia (UBC), and vocal coaching on theatre productions at UBC. The author was a participant and then an associate instructor at Canada’s National Voice Intensive led by David Smukier and Judith Koltai. As well as observing Dale Genge’ s voice class at Langara College’s professional theatre training program, Studio 58, she participated in Richard Armstrong’s International Voice Workshop at the Bauff Centre for the Arts. From this multi-layered learning experience, the author examined a variety of approaches to vocal and physical practices which increased her understanding of the evolution of voice work. She also reviewed her own early vocal development as well as her experience as a voice teacher and coach, and reflected on her pedagogical practice. In this thesis the author describes a greater awareness of the critical role the body plays in vocal work and outlines her discovery of the importance of examining the language used by teachers. She found that asking students to articulate their direct, lived experience aided in student development. As well, she reviewed her previous assumption that teachers choose either a prescriptive teaching model or an exploratory one exclusively, and concluded that there is value in both. Her investigations into the connections between voice and body provide a clearer sense of the breadth of possibility within this work. For the author, this course of study has reinforced the universality of the work: to begin an inquiry into the mysteries of the human voice is to begin to ask ourselves, at the deepest level, who we are.

Stochastic differential equations of fractional order driven by single or multiple fractional Gaussian noise terms are introduced to describe retarding and accelerating subdiffusion and superdiffusion. Short and long time asymptotic limits of the mean squared displacement of the stochastic processes associated with the solutions of these equations are studied. Specific cases of these equations are shown to provide possible descriptions of retarding or accelerating anomalous diffusion.

description: We study the structural and dynamical mechanisms of reinforcement of a polymer nanocomposite (PNC) via coarse-grained molecular dynamics simulations. In a regime of strong polymer-filler interactions, the stress at failure of the PNC is clearly correlated to structural quantities, such as the filler loading, the surface area of the polymer-filler interface, and the network structure. Additionally, we find that small fillers, of the size of the polymer monomers, are the most effective at reinforcing the matrix by surrounding the polymer chains and maximizing the number of strong polymer-filler interactions. Such a structural configuration is correlated to a dynamical feature, namely, the minimization of the relative mobility of the fillers with respect to the polymer matrix.

description: Polymer nanocomposites (PNC) are of great interest owing to the many potential property enhancements possible via introducing different types of nanofillers in polymer matrices. In recent decades, increasing attention has being paid to PNCs due to their light weight, low cost, and ease of processability compared to metal alternatives and due to their novel capability to tune properties. Depending on the end-use application, certain PNCs properties are targeted and the PNC formulation and processing can be manipulated to achieve the desired properties. In this PhD thesis, different PNC properties have been improved by employing different strategies: (1) modification of nanofillers, (2) synthesis of novel nanofillers, (3) implementation of hybrid fillers, and (4) amendment of PNC production methods. For nanofiller modification, chemical treatment of nanoclay, multiwall carbon nanotube (MWCNT) and graphene nanoribbon (GNR) were performed. For the second strategy, GNR was synthesized from parent MWCNT to benefit from higher surface area and interaction of the novel nanofillers with the polymer chains. The main objective of these two strategies is to improve the affinity and dispersion of nanofillers in the host polymer to enhance PNC properties. Utilizing a secondary filler to further enhance the desired properties was the third strategy and was accomplished via a hybrid filler PNC consisting of MWCNT and nanoclay. Finally, the fourth strategy was to develop optimized PNC production methods. The aim of the last two strategies was to obtain an improved morphology for the nanocomposite and it is well known that nanocomposite structure can be used to control the final PNC properties.

description: © 2018 Wickens, Bangasser and Briand. Alterations in glutamate, the primary excitatory neurotransmitter in the brain, are implicated in several psychiatric diseases. Many of these psychiatric diseases display epidemiological sex differences, with either males or females exhibiting different symptoms or disease prevalence. However, little work has considered the interaction of disrupted glutamatergic transmission and sex on disease states. This review describes the clinical and preclinical evidence for these sex differences with a focus on two conditions that are more prevalent in women: Alzheimer’s disease and major depressive disorder, and three conditions that are more prevalent in men: schizophrenia, autism spectrum disorder, and attention deficit hyperactivity disorder. These studies reveal sex differences at multiple levels in the glutamate system including metabolic markers, receptor levels, genetic interactions, and therapeutic responses to glutamatergic drugs. Our survey of the current literature revealed a considerable need for more evaluations of sex differences in future studies examining the role of the glutamate system in psychiatric disease. Gaining a more thorough understanding of how sex differences in the glutamate system contribute to psychiatric disease could provide novel avenues for the development of sex-specific pharmacotherapies.

description: © 2002-2012 IEEE. Mobile edge computing usually uses caching to support multimedia contents in 5G mobile Internet to reduce the computing overhead and latency. Mobile edge caching (MEC) systems are vulnerable to various attacks such as denial of service attacks and rogue edge attacks. This article investigates the attack models in MEC systems, focusing on both the mobile offloading and the caching procedures. In this article, we propose security solutions that apply reinforcement learning (RL) techniques to provide secure offloading to the edge nodes against jamming attacks. We also present lightweight authentication and secure collaborative caching schemes to protect data privacy. We evaluate the performance of the RL-based security solution for mobile edge caching and discuss the challenges that need to be addressed in the future.

We obtain polarimetry data in the J, H, and K_s bands using the SIRIUS polarimeter SIRPOL at the Infrared Survey Facility 1.4 m telescope. We measure the Stokes parameters of 2562 point-like sources to derive the degree of polarization and the polarization position angles. We discuss the statistics of the groups classified by color-magnitude diagram and proper motions of the sources, in order to separate the Galactic foreground sources from those present in the LMC. We notice that groups classified by the proper motion data show a tendency towards different polarimetric properties.

description: Landscape connectivity is the degree to which landscapes are connected among resource patches. Resource patches provide core habitat for wildlife. Considering that connectivity is essential to survival of wildlife, the aim of this research was to model landscape connectivity for wildlife movement over a regional landscape. Functional connectivity was computed for assessing corridors and linkage zones of wildlife movement. Human footprint data was used to compute graph theoretic betweenness centrality for shortest path, current flow and network flow methods. As a result, shortest paths identified a set of geodesic paths; current flow identified a number of movement zones; and network flow identified linkage zones with and without considering costs in the network. The model output was validated with camera-captured and road-killed wildlife data and found strong correspondence. The author concluded by analyzing comparison of the approaches and recommending suitable planning and management options for the study park and the landscape.

description: This dissertation looks back through the lens of a conflict that emerged during the development of social work education in Alberta, and captured by a dispute about the name of the school. The difference of a single word – welfare versus work – led through selected events in the history of social work where similar differences led to disputes about important matters. The themes of the dispute are embedded in the Western Tradition with the emergence of social work and its development at the focal point for addressing the consequences described as a ‘painful disorientation generated at the intersections where cultural values clash.’ In early 1966, the University of Calgary was selected as the site for Alberta’s graduate level social work program following a grant and volunteers from the Calgary Junior League. Initiated in the early 1960s by the AASW, social agencies, representatives from Calgary and Edmonton and the University of Alberta, to conduct a study led by the Alberta Social Work Education Research Committee. The Study completed in 1965 concluded with a recommendation to establish a school of social work in Alberta; the University of Alberta, Board of Governors assigned the school to the new University of Calgary. The Study examines the history of the School of Social Welfare and the controversy surrounding the name associated with the broad view of social work. The critique led to a narrative that its graduates were not prepared for practice. Several efforts were made to change the name; however, AASW aligned itself with the School’s critics to oppose the name change. Following the appointment of a new Dean in the early 1980s, the direction and vision of the program changed. Although the program increasingly reflected a narrow view of social work, its scholarly work in the form of research and publications established its legitimacy and credibility particularly within the University and created the condition for changing the name to the Faculty of Social Work. The role of ideology and the theoretical framework of new institutionalism include a discussion of agency and structure, emergence, philosophical anthropology and the development of the tendency toward isomorphism as the predictor and explanation for organizations in the same field adopting similar organizational forms.

description: In this work we are going to perform a simulation of a wire-cylinder-plate positive corona discharge in nitrogen gas, and compare our results with already published experimental results in air for the same structure. We have chosen to simulate this innovative geometry because it has been established experimentally that it can generate a thrust per unit electrode length transmitted to the gas of up to 0.35 N/m and is also able to induce an ion wind top velocity in the range of 8-9 m/s in air. In our model, the used ion source is a small diameter wire, which generates a positive corona discharge in nitrogen gas directed to the ground electrode, after which the generated positive ions are further accelerated in the acceleration channel between the ground and cathode. By applying the fluid dynamic and electrostatic theories all hydrodynamic and electrostatic forces that act on the considered geometries will be computed in an attempt to theoretically confirm the generated ion wind profile and also the thrust per unit electrode length. These results are important to establish the validity of this simulation tool for the future study and development of this effect for practical purposes.

description: We introduce pymovements: a Python package for analyzing eye-tracking data that follows best practices in software development, including rigorous testing and adherence to coding standards. The package provides functionality for key processes along the entire preprocessing pipeline. This includes parsing of eye tracker data files, transforming positional data into velocity data, detecting gaze events like saccades and fixations, computing event properties like saccade amplitude and fixational dispersion and visualizing data and results with several types of plotting methods. Moreover, pymovements also provides an easily accessible interface for downloading and processing publicly available datasets. Additionally, we emphasize how rigorous testing in scientific software packages is critical to the reproducibility and transparency of research, enabling other researchers to verify and build upon previous findings.

description: The kd-tree is a fundamental tool in computer science. Among other applications, the application of kd-tree search (by the tree method) to the fast evaluation of particle interactions and neighbor search is highly important, since the computational complexity of these problems is reduced from O(N^2) for a brute force method to O(N log N) for the tree method, where N is the number of particles. In this paper, we present a parallel implementation of the tree method running on a graphics processing unit (GPU). We present a detailed description of how we have implemented the tree method on a Cypress GPU. An optimization that we found important is localized particle ordering to effectively utilize cache memory. We present a number of test results and performance measurements. Our results show that the execution of the tree traversal in a force calculation on a GPU is practical and efficient.

subject: Transportation Planning

description: The aim of this research is to better understand the relationship between the presence of hills and the frequency of walking trips for transportation purposes in the City of North Vancouver. The study also explores how a number of other barriers may impact walking frequency. A mixed-method research approach was used that included site analysis, a distributed survey, and the statistical analysis of the collected data. Based on these results, hills were found to have a relationship with walking frequency among certain groups of residents, including individuals over the age of 55 and those with physical disabilities. Other barriers with stronger relationships to walking frequency than hills were, distance to destinations and time constraints. Recommendations based on the study’s findings include providing a greater mix of land uses, more variety of destinations throughout the case study area and direct pedestrian routes that cut down walking trip distance.

Headless but not harmless : the thematics and aesthetics of decapitation in martial epic
Creators: name: McClellan, Andrew Michael
Publisher: name: University of British Columbia
Year: 2010

description: This study looks at decapitation in epic poetry from Homer to the early Imperial Roman epics of Lucan and Statius (Thebaid). I examine a variety of epic instances of decapitation, paying particular attention to the significance and symbolism of decapitation in each author in terms of thematic scope and aesthetics. In Chapter 1, I begin by tracing the development of the theme of decapitation from Homer onwards, culminating in an investigation of the elaborations of the theme by Lucan and Statius. Of particular note here are the sensationally graphic scenes of Pompey’ s murder and headembalming in Lucan (esp. BC 8.663-91), and Melanippus’ decapitation, and Tydeus’ subsequent “brain-eating” of his killer-victim in Statius (Thebaid 8.735-66), which receive fuller treatment in Chapter 2. I also, in an elaboration of Elaine Fantham’ s “Lucan’s Medusa-Excursus: Its Design and Purpose,” and Martha Malamud’s article “Pompey’s Head and Cato’s Snakes,” (CF 2003) consider the figure of Medusa and her decapitation by Perseus as a paradigm for the scenes in Lucan and Statius. Lucan presents a Medusa excursus in Book 9.619-69, framed by Pompey’s decapitation and Caesar’s ‘confrontation’ with the head in Egypt (9.1035-1108), which must be understood as a thematic unit. And frequent references in Statius to the gorgon-head on Pallas Athena’s aegis, particularly in the “brain-eating” scene of Book 8, receive similar analysis. The second chapter also consists of a discussion of audience reaction to scenes of decapitation, and the play of focalization Lucan and Statius create to complicate our viewing of the scenes. I examine reactions that the authors and characters within the epics themselves have to scenes of decapitation as a means of metaliterary readership response. The final chapter examines briefly the aesthetic attraction to scenes of the horrific and grotesque, and specifically the tension and dilemma these scenes create in the reader/viewer. Part of my analysis involves consideration of relevant literature treating the aesthetics of horror, including Plato’s Republic, Aristotle’s Poetics, Julia Kristeva’ s Powers of Horror: An Essay in Abjection (1982), and Noel Carroll’s Philosophy of Horror (1990), to gauge the inherent aesthetic attraction to scenes of the horrific and grotesque.
Mixerless Transmitters for Wireless Communications

description: There is immense research in developing digital transmitters that are multi-standard and reconfigurable. A promising technique is RF Digital to Analog Converter (RFDAC), where the input digital baseband signal is directly converted to an analog RF signal. The existing RFDAC based transmitters use mixers and adopt filtering to avoid mixer spurs. Polar transmitters too use mixers and need filtering. The use of RF filtering in these transmitter topologies limits the bandwidth and therefore the multi-standard reconfigurability of such transmitters. This thesis aims to develop mixerless transmitter architectures that are reconfigurable. A mixerless polar modulator-based transmitter and a mixerless three-way amplitude modulation based transmitter are proposed for OFDM signals. The proposed architectures translate the baseband signal to RF without using mixers. The topologies do not have any emissions over a wide frequency band. The large RF bandwidth and the absence of filters make the designs more reconfigurable and suitable for integration.
