“We are doing this together”: Processes of Feminist Identity Among Professional Counsellors

description: Feminist counsellors can quite simply be understood as counsellors, therapists, or psychologists whose professional identities and related practices are aligned with the values, beliefs, aims, and theoretical underpinnings of feminist ideology. However, feminist ideology, or rather ideologies, are not monolithic or unified undertakings. Instead, feminist counsellor professional identity is informed by feminism(s)’ complex history, rife with incommeasurabilities, heterogeneities, and tensions among the various discourses informing the ideology. As a result, feminist counsellor professional identities represent ongoing relational negotiations that involve encountering and navigating ideological dilemmas − a complexity often overlooked in feminist counselling research. Using social constructionist, situational analysis (SA), I explored the messiness of feminist counsellor professional identity construction and maintenance through an analysis of interviews with nine self-identified feminist counsellors. Through the analytic mapping of participants’ rich descriptions, I identified human and non-human elements related to feminist counsellor professional identity, including “hot-button” tensions: power, feminist values, and responsibility/accountability − sites of discursive contest over the thinking, saying, and doing of feminist counsellors. Through a juxtaposition of these results with a commonly cited developmental model, I invite new conversations regarding what is involved in processes of feminist identity among professional counsellors, advocate for pluralism in the counselling profession, and offer sentiments of feminist solidarity across differences.

description: We present a new publicly available tool (DustPol) aimed to model the polarised thermal dust emission. The module DustPol, which is publicly available, is part of the ARTIST (Adaptable Radiative Transfer Innovations for Submillimetre Telescopes) package, which also offers tools for modelling the polarisation of line emission together with a model library and a Python-based user interface. DustPol can easily manage analytical as well as pre-gridded models to generate synthetic maps of the Stokes I, Q, and U parameters. These maps are stored in FITS format which is straightforwardly read by the data reduction software used, e.g., by the Atacama Large Millimeter Array (ALMA). This turns DustPol into a powerful engine for the prediction of the expected polarisation features of a source observed with ALMA or the Planck satellite as well as for the interpretation of existing submillimetre observations obtained with other telescopes. DustPol allows the parameterisation of the maximum degree of polarisation and we find that, in a prestellar core, if there is depolarisation, this effect should happen at densities of 10^6 cm-3 or larger. We compare a model generated by DustPol with the observational polarisation data of the low-mass Class 0 object NGC 1333 IRAS 4A, finding that the total and the polarised emission are consistent.

description: In this Thesis, I investigate two disparate topics in the fields of quantum information processing and macromolecular biochemistry, inter-related by the underlying physics of nonadiabatic electronic transitions (i.e., the breakdown of the Born-Oppenheimer approximation). The main body of the Thesis is divided into two Parts. In Part I, I describe my proposal for a two-qubit quantum logic gate to be implemented based on qubits stored using the total orbital angular momentum states of ultracold neutral atoms. I carry out numerical analyses to evaluate gate fidelity over a range of gate speeds, and I derive a simple criterion to ensure adiabatic gate operation. I propose a scheme to significantly improve the gate's fidelity without decreasing its speed. I contribute to the development of a “loophole-free” Bell inequality test based on the use of this gate by carrying out an order-of-magnitude feasibility analysis to assess whether the test is viable given realistic technological limitations. In Part II, I investigate electron transfer reaction experiments performed on native and mutant forms of the MADH--amicyanin redox complex derived from P. denitrificans. I implement molecular dynamics simulations of native and mutant forms of the solvated MADH--amicyanin complex. I analyze the resulting nuclear coordinate trajectories, both geometrically and in terms of electronic redox coupling. I find that the interprotein solvent dynamics of the mutant systems differ dramatically from those of the native system, and that the stability of an electron-transfer-mediating ``water bridge'' is compromised in the mutant complexes. I conclude that the mutations disrupt a protective “molecular breakwater” on the surface of amicyanin that stabilizes the interprotein water bridge. I discuss parallels between the nonadiabatic effects as they manifest themselves in the two systems, and I suggest how my findings in Part I promote technological developments to better characterize systems like that examined in Part II.

description: In Germany, transfers of assets between generations are subject to inheritance and gift tax.1 However, there are different views on whether or not the present level of taxation is high enough. Our study looks at the potential for applying increases. We show that the constitutional framework does indeed allow for higher taxation in the case of intergenerational property transfers. We identify the essential points in current German inheritance and gift tax law, which make it possible to transfer large assets with no or low inheritance tax burden. For these points as well as the determination of tax rates, we propose reform approaches and present options for the use of possible additional income.

Mind the gap: inheritance and inequality in retirement wealth

Subjects: Household finance; Retirement saving; Private pension; Intergenerational wealth transfers; Bequest; Inheritance

description: Drawing on detailed German panel data, we find that gifts and inheritances substantially increase households’ private pension savings in accounts which are costly or impossible to withdraw prematurely. Back-of-the-envelope calculations suggest that (a) the average difference in bequest-induced private pension savings between heirs and non-heirs accrues to more than 40,000 euros at retirement, and that (b) it would take an average non-heir household roughly 14 years to match this gap. The sizable difference in private pension savings between heirs and non-heirs persists when we take into account other investments of heirs and non-heirs potentially intended to provide for old age. Our evidence supports the impact of gifts and inheritances on inequality in retirement wealth highlighted in recent research on intergenerational justice. We discuss several policy implications of our results. Online appendix

Questioning the Past: The Fragebogen and Everyday Denazification in Occupied Germany

description: This dissertation examines the infamous denazification questionnaires – Fragebögen – that were distributed by the four Allied occupying powers in Germany following the Second World War and designed to identify Nazi party members and sympathizers. These self-administered surveys, alongside the Nuremberg Trials, were the public face of denazification, but in reality the Fragebogen process dwarfed all other activities in scale, expense, and impact. The questionnaires determined what employment opportunities were available for German citizens and provided the basic personal information for the Allies’ initiatives to deconstruct the Nazi state, establish democratic government, and rebuild Germany’s economic infrastructure. Upwards of twenty million civilians and returning soldiers completed one of these forms, making it the largest international survey in history. This study explores the origin, development, and implementation of this innovative – and highly criticized – instrument of denazification in the American, British, French, and Soviet occupation zones, and evaluates its impact on the lives and livelihood of individual Germans as they recovered from and responded to war and dictatorship. This dissertation ultimately describes how the Fragebogen lay at the heart of the postwar campaign to cleanse the German polity of Nazism. It was a highly experimental solution to the problem of denazification, one that was overseen by the military but written and implemented by civilian specialists and academics. Acting as the fundamental underpinning of each of the Allies’ denazification campaigns, the Fragebogen was never a sufficient instrument for the complex task of screening and judging the German population. But still, the questionnaire had a tremendous impact on the economic security, social standing, and emotional wellbeing of individual Germans. The act of completing the form had a psychological effect, allowing and even encouraging respondents to construct politically and morally acceptable narratives regarding their recent lives under the Third Reich and to establish new identities in order to process wartime experiences of violence and loss and to reconsider notions of guilt and accountability. This study explores the origins of this peculiar instrument of denazification, its influence, consequences, and legacies, and the space that it created for Germans to recreate themselves in the immediate postwar years.

description: We have studied the effect of time-dependent ionization and recombination processes on magnetic reconnection in the solar corona. Petschek-type steady reconnection, in which model the magnetic energy is mainly converted at the slow-mode shocks, was assumed. We carried out the time-dependent ionization calculation in the magnetic reconnection structure. We only calculated the transient ionization of iron; the other species were assumed to be in ionization equilibrium. The intensity of line emissions at specific wavelengths were also calculated for comparison with {\it Hinode} or other observations in future. What we found is as follows: (1) iron is mostly in non-equilibrium ionization in the reconnection region, (2) the intensity of line emission estimated by the time-dependent ionization calculation is significantly different from that with the ionization equilibrium assumption, (3) the effect of time-dependent ionization is sensitive to the electron density in the case that the electron density is less than $10^{10}$ cm$^{-3}$, (4) the effect of thermal conduction lessens the time-dependent ionization effect, (5) the effect of radiative cooling is negligibly small even if we take into account time-dependent ionization.

On Hydraulic Fracturing of Tight Gas Reservoir Rock

subject: hydraulic fracturing

description: Production of shale and tight gas resources is increasing which is helping to counterbalance the conventional gas resource production decline. In 2014, shale and tight gas were 4% and 47% of total Canadian natural gas production, respectively. By 2035, the National Energy Board forecasts shale and tight gas production together will represent 90% of Canada’s natural gas productions. In Canada, shale and tight gas production activities are located mainly in Western Canada Sedimentary Basin (WCSB). The tight gas Glauconitic Formation in the Hoadley Field in Alberta, Canada requires hydraulic fracturing of horizontal well completions because of its low permeability of 0.07 mD. Fracture network drainage volume and enhanced permeability created by the hydraulic fracture and the natural fracture interaction are the major enabler of commercial production. The research documented in this thesis investigates the characteristics of the fracture network or stimulated rock volume (SRV) caused by hydraulic fracturing. Specifically, the dimensions of SRV, permeability, pore pressure, and in-situ stresses are examined during hydraulic fracturing and production. Even though this topic has been examined since the early 2000s, the results provide new techniques to determine SRV properties. Three different approaches were investigated. The first handles the impact of SRV dimensions and Young’s modulus on the SRV effective permeability during hydraulic fracturing by using three-dimensional finite element analysis including an investigation of fracture aperture and spacing within the SRV using a new semi-analytical approach. The second investigates the impact of rock mechanical properties and injected volume during hydraulic fracturing on SRV dimensions using a new analytical model. The third explores a new nonlinear partial differential equation together with rate transient analysis to evaluate how the SRV evolves versus distance and time with a history match of the gas flow rate profile. The results demonstrate that the dimensions and characteristics of the hydraulic fracture network can be estimated for the Hoadley Field.

description: We analyze the dynamical generation of entanglement in systems of two interacting spins initially prepared in a product of spin coherent states. For arbitrary time-independent Hamiltonians, we derive a semiclassical expression for the purity of the reduced density matrix as function of time. The final formula, subsidiary to the linear entropy, shows that the short-time dynamics of entanglement depends exclusively on the stability of trajectories governed by the underlying classical Hamiltonian. Also, this semiclassical measure is shown to reproduce the general properties of its quantum counterpart and give the expected result in the large spin limit. The accuracy of the semiclassical formula is further illustrated in a problem of phase exchange for two particles of spin $j$.

Anti-Hermes: Examining Deleuze, Communication, and Power in the Twenty-First Century

Publisher: name: Graduate Studies
Year: 2017
Subjects: subject: Mass Communications
subject: post-structuralism
subject: control
subject: power
subject: communication theory
subject: movement

description: This dissertation conceives of a post-structuralist philosophy of communication as informed by Gilles Deleuze (1925-1990). This philosophy of communication is based upon two things. First, within the primary literature, the problem of power is a consistent thread around which Deleuze organizes his concepts. Two, concurrent with his analysis of power, Deleuze produces a disparate critique of communication itself that develops and matures across the decades of the 1970s, 1980s, and 1990s, in which he moves from ideas of transmission, information, and opinion, respectively, to focus his analysis of the relationship between power and communication. However, while the history of Communication Studies has also evinced an interest in this relationship between power and communication, the field has not taken up Deleuzian philosophy as a viable mode of theoretical inquiry to further address this association. This dissertation seeks to address this gap. To make the Deleuzian perspectives about power and communication translatable in terms that are relevant to Communication Studies, this dissertation engages in a close reading of Deleuze’s “Postscript of the Societies of Control” essay (1992), in which control is described as several things—the opening of confined spaces, the breakdown of social institutions, and the materialization of communication in practices of technology, labour, and economics. However, this dissertation explains, expands upon, and critiques these perspectives on control that Deleuze only sketches in this essay. Additionally, to make the link between Deleuzian post-structuralism and Communication Studies more cogent, the Deleuzian descriptions of control are thematized on the level of movement, which are treated as both concrete and analogical, which situates one’s freedom by modulating the capacity to move altogether. On one hand, control-as-movement is concrete, since messages, smartphones, capital, information, and people are all things in the world that move from one point to another. On the other hand, control-as-movement is analogical, as much as power and communication have been modelled by Communication Studies as being unilinear and unidirectional, from a sender to a receiver. And yet, today, control is multilinear and multidirectional, within which power and communication are omnipresent.

Within a quantum field theoretical model a two-step Gaussian approximation allows to capture the main features of the quantum phase diagram. We show that a repulsive boson-boson interaction is necessary for thermodynamic stability. The quantum phase diagram is mapped in chemical potential and density space, and both first and second order quantum phase transitions are found. We discuss typical characteristics of the first order transition, such as hysteresis or a droplet formation of the condensate which may be searched for experimentally.

Targeting the PI3K and Ras Signal Transduction Pathways in a Murine Model of Osteolytic Breast Cancer Metastasis

description: Bone metastasis frequently occurs in patients with advanced breast cancer, and leads to widespread bone destruction. Aberrant activation of the PI3K and Ras-MAPK pathways are consistently observed in high-grade metastatic breast cancers, making these pathways attractive targets for therapeutic intervention. Complex signal crosstalk between these pathways is implicated in cancer cell perpetuation; therefore, dual inhibition should theoretically provide maximal targeting. The PI3K and MEK inhibitors, PX866 and AZD6244 were employed to investigate the therapeutic potential in an in vivo model of MDA-MB-231-EGFP/Luc2 human breast cancer osteolytic metastases. PI3K inhibition did not directly affect bone-colonized cancer cells, however, it demonstrated an attenuation of bone loss, whereas MEK inhibition resulted in a significant reduction of both tumor growth and osteolysis. Simultaneous inhibition of PI3K and MEK resulted in a reduction of tumor growth, but paradoxically exhibited an exacerbation of bone damage. These findings suggest that MEK inhibition alone may be a valuable additional treatment for breast cancer osteolytic metastasis.
Making a Model Metropolis: Boosterism, Reform, and Urban Design in Minneapolis, 1880-1920

Subjects: subject: History--United States

subject: Progressive Era

description: In 1883, the Minneapolis Park Board commissioned Horace Cleveland to develop a system of parks. Cleveland delivered more than lines on a map. He urged Minneapolitans to recognize the important roles that aesthetics and environment played in developing a successful city. This became part of a foundational ethos for civic leaders and social reformers who worked to cultivate an identity for Minneapolis as a beautiful city that would, by design, evade the slums and overcrowding of older cities and to set it apart from all others. The collaboration between Cleveland and the Park Board was but one project of middle- and upper-class civic leaders and social reformers who positioned themselves as stewards of the city’s social and physical development. Though their motivations occasionally diverged, they shared the same goal: to help Minneapolis avoid the perils of urbanization and make it a model metropolis. Combining programming with environmental interventions, they targeted workplaces, homes, schools, sites of consumption and leisure, and city parks. Using studies on contemporary conditions produced by civic leaders and social reformers, personal papers, and plans for civic space, this dissertation examines the sites social reformers and civic leaders targeted and the ways that they sought to reform the people by re-forming the city. This dissertation examines both physical and ideological developments in the process of city formation in Minneapolis. It situates Minneapolis as engaged in and contributing to national and international ideologies on labor, education and schools, consumption, leisure and recreation, urban design, and housing. It interrogates how the city’s eastern-born civic leaders and boosters conceptualized an identity for Minneapolis that transcended its location on the edge of the West. Unlike many other municipalities during this time, civic leaders and social reformers attempted to guide rather than control the behavior of the city’s working class. In so doing, they built a network of stewardship that developed programming and redemptive places to entice Minneapolitans away from “deleterious” venues with “base” content and used environmental interventions to reconfigure the city into an uplifting and beautiful place.

description: High-precision measurements of the temperature and polarization anisotropies of the cosmic microwave background radiation have been previously employed to set robust constraints on dark matter annihilation during recombination. In this work we improve and generalize these constraints to apply to energy deposition during the recombination era with arbitrary redshift dependence. Our approach also provides more rigorous and model-independent bounds on dark matter annihilation and decay scenarios. We employ principal component analysis to identify a basis of weighting functions for the energy deposition. The coefficients of these weighting functions parameterize any energy deposition model and can be constrained directly by experiment. For generic energy deposition histories that are currently allowed by WMAP7 data, up to 3 principal component coefficients are measurable by Planck and up to 5 coefficients are measurable by an ideal cosmic variance limited experiment. For WIMP dark matter, our analysis demonstrates that the effect on the CMB is described well by a single (normalization) parameter and a "universal" redshift dependence for the energy deposition history. We give WMAP 7 constraints on both generic energy deposition histories and the universal WIMP case.

Influence of Roughness on the Flow Behavior along the Hydrodynamic Interface for Steady Laminar Flows

description: The increasing implementation of mini and microchannels in industrial or biomedical applications is a source of novel challenges for pressure drop. Pressure loss due to surface roughness for flows in microchannels is reported to deviate from conventional macroscale theory in both the laminar and turbulent regime even for small relative roughness (less than 5% of the hydraulic diameter). This work aims to characterize the influence of the geometry parameters of Q-type structured surface roughness on the hydraulic performance in two-dimensional rectangular channels under steady laminar flow. The surface roughness is modeled as spatially periodic rectangular elements, which is commonly used for micro heat exchangers. Computational Fluid Dynamics (CFD) is used to solve the governing continuity and momentum equations. The selected roughness parameters are typical for industrial microdevices (e.g. micro heat exchangers) and biomedical systems. It is shown that the pressure drop is larger in both mini and microchannels when compared to conventional channels for relative roughness less than 5%. Different flow regimes are identified. A novel correlation between pressure drop and roughness characteristics is developed. Predictions are compared to the available literature for similar roughness configuration and results show good agreement. Although the proposed correlation is defined for Q-type structured roughness, the predictions are of acceptable accuracy for other roughness geometries. The results led to the proposal of a simplified approach for modeling the influence of distributed surface roughness on bulk flow parameters through a prescription of boundary condition on the rough wall for laminar and steady duct flows. This approach promises to predict the averaged velocity profile above the roughness amplitude without detailing flow behavior near the rough wall.
Fundamentals of software design science
Creators: name: Ralph, David Paul
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation comprises three essays on software design science, the philosophical, theoretical and empirical study of software creation and modification including its phenomenology, methodology and causality. The essays consider three limitations evident in the software design science literature: 1) lack of a precisely-defined, well-understood vocabulary; 2) difficulties surrounding empirical research; 3) lack of theory concerning the design process’s structure and organization. The first essay presents an extensive review of definitions of design, revealing nontrivial disagreements regarding its nature and scope. Following this, a formal definition of design and a conceptual model of design projects are constructed. The definition incorporates seven elements – agent, object, environment, goals, primitives, requirements and constraints. The conceptual model views design projects as temporal trajectories of work systems, in which human agents design systems for stakeholders, using resources and tools. This provides a detailed, defensible basis for theoretical and empirical software design science research. The second essay addresses the difficulties of empirical software design science research by elucidating a broad, bipolar conflict in design literature between two incompatible beliefs: 1) the belief that design is an innately cognitive, approximately rational, plan-centered activity (Reason-Centric Perspective); 2) the belief that design is an emergent phenomenon, improvised through continual interaction between agents and environments (Action-Centric Perspective). Each perspective is operationalized through a software design process theory: the Function-Behavior-Structure Framework (chosen for the Reason-Centric Perspective) and the Sensemaking-Coevolution-Implementation Framework (proposed for the Action-Centric Perspective). The third essay presents a survey study comparing these perspectives and theories. Responses from 1384 software development professionals in 65 countries indicate that the Sensemaking-Coevolution-Implementation Framework more accurately describes the structure and organization of their design processes than the Function-Behavior-Structure Framework. Gender, education, experience, nationality, occupation, team size, project duration, firm size, methodologies in use, and the nature of the software had no measurable effect on this finding. This supports a theory of the design process’s structure and organization and facilitates several streams of empirical research including studies of design project success.

description: Context. OB stars are important building blocks of the Universe, but we have only a limited sample of them well understood enough from an asteroseismological point of view to provide feedback on the current evolutionary models. Our study adds one special case to this sample, with more observational constraints than for most of these stars. Aims. Our goal is to analyse and interpret the pulsational behaviour of the B3 IV star HD 43317 using the CoRoT light curve along with the ground-based spectroscopy gathered by the Harps instrument. This way we continue our efforts to map the Beta Cep and SPB instability strips. Methods. We used different techniques to reveal the abundances and fundamental stellar parameters from the newly-obtained high-resolution spectra. We used various time-series analysis tools to explore the nature of variations present in the light curve. We calculated the moments and used the pixel-by-pixel method to look for line profile variations in the high-resolution spectra. Results. We find that HD 43317 is a single fast rotator (v_rot ~ 50% v_crit) and hybrid SPB/Beta Cep-type pulsator with Solar metal abundances. We interpret the variations in photometry and spectroscopy as a result of rotational modulation connected to surface inhomogeneities, combined with the presence of both g and p mode pulsations. We detect a series of ten consecutive frequencies with an almost constant period spacing of 6339 s as well as a second shorter sequence consisting of seven frequencies with a spacing of 6380 s. The dominant frequencies fall in the regime of gravito-inertial modes.

National university system.

description: The Sri Lankan education system is structured into three key stages, spanning 13 years, starting from primary school to college-level education. The journey comprises primary education (Grades 1-5), junior secondary education (Grades 6-9), senior secondary education (Grades 10-11), and college-level education (Grades 12-13). Notably, the Grade 5 scholarship and General Certificate Examination, Ordinary Level (GCE O/L), are highly competitive, as they hold the key to better educational opportunities. Success in the Grade 5 scholarship exam opens doors to improved schools, while a strong performance in the O/L exam offers students the chance to choose between different subject streams, including Arts, Science, Maths, and Commerce. Furthermore, the GCE Advanced Level (GCE A/L) examination is a pivotal point in the educational journey, as it grants access to government universities. Exceptional achievers at the A/L examination can secure admission to the national university system.

description: A theoretical and experimental study of the propagation of sound beams in- and behind three-dimensional sonic crystals at frequencies close to the band edges is presented. An efficient collimation of the beam behind the crystal is predicted and experimentally demonstrated. This effect could allow the design of sources of high spatial quality sound beams.

Can planting trees bring co-benefits? : smallholder tree planting for development and carbon mitigation
Creators: name: Anderson, Emily Kathryn
Publisher: name: University of British Columbia
Year: 2010

description: There has been a growing interest in land-use change and forestry activities for advancing the global goals of climate change mitigation and rural development. Because of its links to agriculture, the main livelihood activity of the rural poor in most developing countries, one particularly promising land-use is agroforestry, the use of land for both agricultural and silvicultural activities. The potential for agroforestry to deliver rural development and climate change mitigation benefits is well documented. There is considerable hope and expectation that agroforestry will be able realize co-benefits, where projects seek simultaneous goals of improving human welfare and mitigating climate change. However, it is less clear how and whether both goals might be accomplished in practice. Through an analytical literature review of rural development and carbon forestry literature, and a qualitative case study of participant experiences and understandings in smallholder tree planting initiatives in Uganda, this thesis explored the following overarching research questions: 1. What are areas of likely tension and synergy when smallholder agroforestry projects in developing countries attempt to realize co-benefits for rural development and climate change mitigation? 2. How should smallholder planting projects be designed to effectively maximize the delivery of benefits for both development and carbon goals? Both the case study and review of the literature suggest that projects seeking co-benefits from smallholder tree planting initiatives will encounter substantial tension between practices best suited to realizing development versus carbon benefits. These projects have considerable potential to fail in meeting expectations. Explicitly seeking ancillary benefits in projects that have primary goals of development or climate change mitigation may be a more effective way to more quickly expand the use of smallholder planting projects and attain both types of benefits, while concurrently providing opportunities to learn from experience and move towards the development of best practice for delivering returns for carbon and development on the ground. Alternative approaches to project design and pathways to deliver development benefits may be more appropriate in smallholder carbon projects to overcome expected tensions in projects attempting to deliver both development and climate benefits.
Homogenization of a stochastic nonlinear reaction-diffusion equation with a large reaction term: the almost periodic framework

description: Homogenization of a stochastic nonlinear reaction-diffusion equation with a large non- linear term is considered. Under a general Besicovitch almost periodicity assumption on the coefficients of the equation we prove that the sequence of solutions of the said problem converges in probability towards the solution of a rather different type of equation, namely, the stochastic non- linear convection-diffusion equation which we explicitly derive in terms of appropriated functionals. We study some particular cases such as the periodic framework, and many others. This is achieved under a suitable generalized concept of sigma-convergence for stochastic processes.

COOPERATIVE COMMUNICATIONS FOR LTE-ADVANCED SYSTEMS: DOWNLINK RELAY AND PERFORMANCE OPTIMIZATION

description: The Third Generation Partnership Project's Long Term Evolution-Advanced (LTE-A) is considering an option for relay networks to provide cost-effective throughput enhancement and coverage extension. While analog repeaters have been used to enhance coverage in commercial cellular networks, the use of more sophisticated fixed relays is relatively new. The main challenges faced by relay deployments in cellular systems are designing an improved and efficient relaying protocol, improving the desired signal and overcoming the extra interference added by the presence of relays specifically at cell-edge regions. Most prior works on relaying do not consider relay integration in cellular LTE-A systems. In this dissertation, we propose and investigate the performance of a modified relaying protocol, the Enhanced-Decode-and-Forward (E-DF), which improves diversity and data rate and reduces the symbol error rate. The dissertation also proposes and analyzes the performance of several half-duplex downlink relay schemes in interference-limited cellular systems. These schemes are – The Omni-Relay (OR) scheme, The Directional-Relay (DR) scheme and The In-band Relay (IR) scheme. The average signal-to-interference plus noise ratio and average capacity performances of each scheme are analyzed for each relay type, antenna pattern as well as power and frequency resources allocation.

description: Pumping of electrons through nano-scale devices is one of the fascinating achievements in the field of nano-science with a wide range of applications. To optimize the performance of pumps, operating them at high frequencies is mandatory. We consider the influence of fast periodic driving on the average charge transferred through a quantum dot. We show that it is possible to reverse the average current by sweeping the driving frequency only. In connection with this, we observe a rectification of the average current for high frequencies. Since both effects are very robust, as corroborated by analytical results for harmonic driving, they offer a new way of controlling electron pumps.
