Interference Modelling and Analysis of OFDM in Wireless Environments

The ubiquity of mobile broadband wireless communication systems in today’s world is a testament to the robustness and success of radio-based telecommunications. Since the emergence of commercial cellular systems in the early 1980s, there has been an explosive growth in the demand and development of high data rate, large capacity and low cost wireless systems. Furthermore, the demand for mobile broadband connectivity is growing at an exponential rate with so many devices available to consumers that have inbuilt wireless connectivity, e.g. smart phones, laptops and tablets. However, as more wireless systems are deployed in the license-exempt bands (e.g. the ISM band), they are more likely to interfere with close proximity systems due to the inherent nature of the unlicensed radio spectrum. Interference is one of the key factors that limit the performance of wireless systems. Therefore, to deliver high-performance wireless systems, understanding the interference mechanism(s) to a particular system is crucial. One prominent technology that is gaining popularity with contemporary wireless systems (both in the licensed and unlicensed radio spectra) is Orthogonal Frequency Division Multiplexing (OFDM). Most current wireless local area networks (WLANs) and fourth generation (4G) cellular systems, such as the long term evolution (LTE) have adopted OFDM as their physical layer air interface technology. This popularity of OFDM among contemporary wireless systems is one of the major motivations for the research presented here. This thesis presents an analysis into the error rate performance of OFDM-based wireless networks in the presence of multiple interferers as well as a performance comparison with DS-SS wireless systems under identical environmental conditions. Novel analytical expressions that accurately predict the raw error rate (symbol and bit) performance of a generic M -ary QAM OFDM system in the presence of multiple narrowband and generic Z-ary QAM OFDM interferers are derived. The OFDM interferers are considered to be of the same type as the desired system, e.g. all desired and interfering OFDM systems are IEEE 802.11g WLANs. The analytical expressions are validated against Monte Carlo numerical methods. A computationally efficient algorithm that estimates the OFDM raw error rate performance with sufficient accuracy levels is also proposed. The analytical models developed in this thesis are independent of a particular wireless standard and thus can be used as a tool in the design and planning of OFDMbased wireless systems. These models are used in conjunction with experimental RF measurements to test the implications for system deployment in indoor environments.

The Anticoagulants of Choice for Platelet Transfusions

A study was made of the recovery of Cr51‐labeled platelets transfused to normal recipients using various anticoagulant solutions. With ethylenediamine‐tetra‐acetate (EDTA) recoveries averaged 27 per cent (range 15% to 35%). With ACD (N.I.H. formula A) recoveries averaged 37 per cent (range 34% to 41%). With a citrate solution containing additional acid so as to reduce the pH of platelet‐rich plasma to 6.5 before concentration of cells, recoveries averaged 62 per cent (range 37% to 81%). Platelet clumping, usually a problem when platelets are concentrated in citrate, was prevented at pH 6.5. It is suggested that a citrate solution containing sufficient acid to buffer platelet‐rich plasma at pH 6.5 will increase the effectiveness of platelet concentrates.
Library Services for Users of Personal Digital Assistants: A Needs Assessment and Program Evaluation

Research was undertaken to guide development of services for personal digital assistant (PDA) users at the University of Alberta Libraries. A variety of qualitative methods were used to assess user satisfaction with current PDA services and identify potential PDA services for the libraries and resources. The research and needs assessment results demonstrate an emerging interest in PDA technologies supported by the libraries, as well as the types of services and resources users would value. Results guided the libraries' direction and encouraged further expansion of services.
A survey of Kolmogorov quotients

Every topological space has a Kolmogorov quotient that is obtained by identifying topologically indistinguishable points, that is, points that are contained in exactly the same open sets. In this survey, we look at the relationship between topological spaces and their Kolmogorov quotients. In most natural examples of spaces, the Kolmogorov quotient is homeomorphic to the original space. A non-trivial relationship occurs, for example, in the case of pseudometric spaces, where the Kolmogorov quotient is a metric space. We also look at the topological indistinguishability relation in the context of topological groups and uniform spaces.
Effectiveness of Telephone-Based Therapy in the Management of Depression: A Systematic Review and Meta-Analysis

Background: There are a couple of independent studies examining the effectiveness of telephone based therapy for the treatment of depression. However, up-to-date systematic reviews are lacking. Objective: To evaluate the effectiveness of telephone-based therapy in the management of patients suffering from depression compared with the usual care. Methods: A systematic review and meta-analysis of randomized controlled trials was conducted that compared telephone-based therapy with usual care for depression. We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and CENTRAL (up to August 28, 2012) to identify eligible studies. The primary outcome was depression level at the end of the intervention. We pooled the mean depression level data from the studies using standardized mean difference using the random-effects model. Results: A total of 11 studies met the inclusion criteria. Nine of these studies was considered for the pooled analysis. Comparison of depression levels in the immediate post-intervention period from the seven studies included in the pooled analysis was in favour of telephone-based therapy (standardized mean difference = -0.43; 95% CI: -0.74-0.12). In the remaining two studies, telephone-based therapy resulted in a statistically significant improvement in clinical outcomes and patient satisfaction. A longer duration of intervention and the presence of known medical comorbidity was positively associated with the effectiveness of telephone-based therapy. The overall effect was stable when studies with extreme characteristics were excluded. Intervention results were found to be sustained throughout the follow-up period.
Comprehensive Care for Children With Cancer and Their Families: A Social Ecological Framework Guiding Research, Practice, and Policy

Comprehensive care for children with cancer is complex, multisystemic, and dynamic. At its optimum, it includes an organizing model or framework, effective and cost efficient clinical services for children and their families, and a close feedback link between clinical research and practice. Treatment teams for children with cancer at most children's hospitals in the United States include psychosocial professionals. Using a social ecological perspective, we illustrate multiple opportunities and challenges related to the sustenance of a comprehensive care program for children with cancer and their families program over time, and across systems. The interplay between clinical practice and research is emphasized, along with examples of interdisciplinary family-centered collaboration related to procedural pain, psychological sequelae of childhood cancer survival, and assessment of risk for ongoing psychological distress.

Low-cost, multiplexed biosensor for disease diagnosis

Cost-effective disease diagnosis in resource-limited settings remains a critical global health challenge. Qualitative rapid tests based on lateral flow technology provide valuable screening information, but require relatively expensive confirmatory tests and generally lack quantitation. We report on a fluorescence technology that combines low cost instrumented readout with passive pumping in a disposable cartridge. The detection system utilizes a novel waveguide illumination approach in conjunction with commercial CMOS imagers. Total instrument cost in production are projected to be around $100 This cost structure and instrument ease of use will enable use in point-of-care settings, outside of centralized laboratories. The system has been used for detection and analysis of proteins, antibodies, nucleic acids, and cells. Here we will report first on our development of a multiplexed, array-based serology assay for HIV and common AIDS co-infections. Data will be presented for HIV/HCV antibody testing in human serum samples. In addition, we will present data on the use of the system for sensitive detection of bacterial RNA. Current detection limit for the model multiplexed RNA sandwich assay is 1 femtomolar target RNA. Finally, a high magnification version of the system is used to image immunostained human T cells.
Links among perceived service quality, patient satisfaction and behavioral intentions in the urgent care industry: Empirical evidence from college students.

Patient perceptions of health care quality are critical to a health care service provider's long-term success because of the significant influence perceptions have on customer satisfaction and consequently organization financial performance. Patient satisfaction affects not only the outcome of the health care process such as patient compliance with physician advice and treatment, but also patient retention and favorable word-of-mouth. Accordingly, it is a critical strategy for health care organizations to provide quality service and address patient satisfaction. The urgent care (UC) industry is an integral part of the health care system in the United States that has been experiencing a rapid growth. UC provides a wide range of medical services for a large group of patients and now serves an increasing population. UC is becoming popular because of the convenient locations, extended hours, walk-in policy, short waiting times, and accessibility. A closer examination of the current health care research, however, indicates that there is a paucity of research on urgent care providers. Confronted with the emergence of the urgent care industry and the increasing demand for urgent care, it is necessary to understand how patients perceive urgent care providers and what influences patient satisfaction and retention. This dissertation addresses four areas relevant to the above mentioned issues: (1) development of an instrument to measure perceived service quality in the urgent care industry; (2) identification of the determinants of patient satisfaction and behavioral intentions; (3) empirical examination of the relationships among perceived service quality, patient satisfaction and behavioral intentions; and (4) comparison of the perceived service quality across several primary urgent care providers, such as urgent care centers, hospital emergency departments, and primary care physicians' offices. To validate this new instrument and examine the hypothesized relationships proposed in this study, an electronic web based survey was designed and administered to college students. Both exploratory and confirmatory factor analysis were employed to assess the reliability and validity of the developed instrument. The contextualized relationships were evaluated using structural equation modeling. The results of this research could potentially contribute to urgent care management and quality improvement.
Single-trial analysis of post-movement MEG beta synchronization using independent component analysis (ICA)

The human brain /spl sim/20 Hz rhythm measured by electroencephalography (EEG) and magnetoencephalography (MEG) has been used as a clinical examination index of motor function which originates in the anterior bank of the central sulcus in the human brain. In human voluntary movement, it is composed of three phases, planning, execution and recovery which has been suggested that localized event-related alpha desynchronization (ERD) upon movement can be viewed as an EEG/MEG correlate of an activated cortical motor network, servicing planning and execution, while beta event-related synchronization (ERS)may reflect deactivation/inhibition during the recovery phase in the underlying cortical network. The single-trial detection of /spl sim/20 Hz rhythm is challenged because of its low signal amplitude and its signal-to-noise ration (SNR) in EEG/MEG measured neural activities. This present study proposes a method based on independent component analysis (ICA) for extraction of the sensorimotor rhythm from magnetoencephalography (MEG) measurements of right finger lifting task in a single trail. ICA decomposes a single trial recording into a set of temporal independent components (IC) and corresponding spatial maps in which the task-related components are selected by visual inspection. Pertinent ICs are then selected by visual inspection to reconstruct task-related components beta oscillatory activity which is then subjected to beta rebound quantification and source estimation in further analyses. Since the event-related oscillatory activity of human brain is related to subject's-related oscillatory activity of human brain is related to subject's performance and state, the ICA-based single trial method enables the possibility of studying a single-trial, which in turn may shed light on the intricate dynamics of the brain.
Compliant motion control and redundancy resolution for kinematically redundant manipulators

An augmented hybrid impedance control (AHIC) scheme is proposed for kinematically redundant manipulators. The hybrid impedance control (HIC) scheme, which has been used in the past for compliant motion control of non-redundant manipulators, is extended to the redundant case. It is shown that by appropriately combining redundancy resolution with the hybrid impedance control scheme, one can simultaneously achieve the regulation of the end-effector interaction with the environment and satisfy user defined additional tasks. This is done by augmenting the task space by additional constraints. An augmented Cartesian target acceleration (ACTA) trajectory is generated in real-time. An extension of the configuration control approach at the acceleration level is then used to find the joint target acceleration (JTA) trajectory. A feedback linearization loop is implemented in joint space to ensure the tracking of the JTA trajectory. Different additional tasks are represented by appropriate kinematic functions and the possibility of having a multi-point force-control scheme is presented.
Basic Polynomial Algebra Subprograms

The Basic Polynomial Algebra Subprograms (BPAS) provides arithmetic operations (multiplication, division, root isolation, etc.) for univariate and multivariate polynomials over prime fields or with integer coefficients. The code is mainly written in CilkPlus [11] targeting multicore processors. The current distribution focuses on dense polynomials and the sparse case is work in progress. A strong emphasis is to put on adaptive algorithms as the library aims at supporting a wide variety of situations in terms of problem sizes and available computing resources. One of the purposes of the BPAS project is to take advantage of hardware accelerators in the development of polynomial systems solvers. The BPAS library is publicly available in source at www.bpaslib. org.

Antioxidant capacity and radioprotective properties of the flavonoids galangin and kaempferide isolated from Alpinia galanga L. (Zingiberaceae) against radiation induced cellular DNA damage

Background: Alpinia galanga L. belonging to the family Zingiberaceae is widely grown in the state of Kerala, India. They are effec ve an oxidant and free radical scavenger under both in vitro and in vivo condi on. The efficacy of the isolated flavonoids in conferring protec on from radia on induced damages to genomic DNA was studied. Materials and Methods: The bioflavonoids, galangin and kaempferide were isolated from the AE frac ons Alpinia galanga. The isolated flavanoids ‐ galangin and kaempferide, and the crude extracts (AE and EE) were assayed for their various free radical scavenging ac vi es like DPPH (1,1‐diphenyl‐2‐picryl‐hydrazyl), hydroxyl and superoxide radical scavenging ac vi es. The in vitro DNA damage was monitored by assessing the radia on induced relaxa on of supercoiled plasmid DNA (pBR 322). Damage to cellular DNA of human peripheral blood leukocytes induced by γ‐radia on (4 Gy) was monitored by alkaline single cell gel electrophoresis or comet assay. Results: The extracts and pure compounds scavenged hydroxyl radicals in a concentra on dependent manner. The compounds demonstrated a concentra on dependent scavenging capacity by neutralizing the superoxide radicals. A considerably lower concentra on (400‐1000 ppm) of the pure flavonoids showed good an oxidant capacity. The presence of 10 mM kaempferide helped in reducing the extent of DNA damage following 4 Gy gamma irradia on (P<0.001). Galangin (10 mM) also facilitated in reduc on of comet parameters. Conclusion: The extracts of Alpinia galanga or the isolated bioflavonoids ‐ galangin and kaempferide can protect DNA from radia on induced lesions resul ng from radia on exposures under in vitro and ex vivo condi ons.
