Subjects: subject: Engineering, Electronics and Electrical.

description: Wavelength Division Multiple Access (WDMA) networks are likely to play a key role in future telecommunication infrastructure. The research work is divided into two parts. In the first part, the design of WDMA ring ATM-based local-area network architectures and the photonic components, including optical Add-Drop Multiplexers for architectural implementation, are studied. Based in this, the physical constraints of these components on the overall network performance are explored. The emphasis is placed on gaining a theoretical understanding from the modeling of the random gain of cascaded optical amplifiers in WDMA ring ATM-based local-area networks with optical Add-Drop Multiplexers. With the advent of fiber optic LAN research, a major issue that has surfaced is the interconnection of optical LANs using fiber optic technology. In the second part of this thesis, the WDMA fiber ring ATM-based LANs proposed previously are taken as the basic building elements in the low layer of the proposed hierarchical three-layer all-optical wide-area network architecture. At the top layer, an ultra-high capacity photonic ATM switch based on ultra-short optical pulse time/frequency division and wavelength division multiplexing is proposed and studied as a part of the backbone wide-area lightwave network that interconnects the intermediate layer networks.

Subjects: subject: Engineering, Electronics and Electrical.

description: Impulse noise is an ever increasing impediment to successful digital data transmission in the telephone local cable plant. Two major factors have caused this to happen. Firstly, remedies have been found for nearly all the other causes of signal degradation, such as crosstalk and intersymbol interference, leaving impulse noise outstanding. Secondly, the user's demand for higher and higher data rates and the proliferation of repeaterless operation at extended loop ranges, have made the effects of impulse noise more prominent. This thesis covers the subject of impulse noise in the local plant. It begins with experimental data obtained from field studies of the local loop segments of digital transmission systems. The theoretical aspects of impulse noise are next addressed, including the various methodologies for modeling it. Burst errors in the recovered data stream, and their relationship with impulse noise, their principal cause, are described. The methodologies for modeling burst errors are then discussed. Finally, the techniques for minimizing the harmful effects of impulse noise are examined. Included in this is a novel scheme, referred to as "Pulse Sharpening", now being introduced.

description: Metaphyton is a poorly studied algal community that can develop into large floating mats in rivers, wetlands and lakes. In this thesis, I examined the role of nutrients in determining differences in metaphyton biomass both seasonally and spatially within a lowland temperate river, the Rideau River, Ontario. The source of nutrients was also examined by analyzing the stable isotope signature of the mats in relation to adjacent land-use. Metaphyton in the river was restricted to slow-flowing areas of the littoral zone and was mainly comprised of filamentous green algae (Spirogyra and Cladophora). From the results of this study, conditions for the presence of large metaphyton communities in rivers include: (1) shallow littoral zones with minimal current, (2) the presence of macrophytes (as a substratum), and (3) moderate to high nutrient concentrations (particularly dissolved inorganic nitrogen). To control metaphyton in the Rideau River, the nitrogen loading to the system must be considered as well as phosphorus. (Abstract shortened by UMI.)

description: Background Obesity and its health consequences will dominate health care systems in many countries during the next decades. However, the body mass index (BMI) optimum in relation to all-cause mortality is still a matter of debate. Material and Methods Data of the Vorarlberg Health Monitoring & Prevention Program (VHM&PP, 1985-2005) and data provided by the Main Association of Austrian Social Security Institutions (MAASSI, 2005-2015) were analyzed. Information was available on age, sex, smoking status, measured height and weight, and mortality. Generalized additive models were used to model mortality as a function of BMI, calendar time, age, and follow-up. Results In MAASSI (N=282,216, 46.0% men), men and women were on average 2.7 years older than in VHM&PP (N=185,361, 46.1% men). Average BMI was slightly higher in men (26.1 vs. 25.7 kg/m2) but not in women (24.6 vs. 24.7 kg/m2). We found an interactive effect of age and follow-up on the BMI optimum. Over age 35 in men and 55 years in women, the BMI optimum decreased with length of follow-up. While keeping covariates fixed, BMI optimum increased slightly between 1985 and 2015 in men and women, 24.9 (95%-CI, 23.9-25.9) to 26.4 (25.3-27.3), and 22.4 (21.7-23.1) to 23.3 (22.6-24.5) kg/m2, respectively. Conclusion Age and length of follow-up have a pronounced effect on the BMI associated with the lowest all-cause mortality. After controlling for age and length of follow-up, the BMI optimum increased slightly over 30 years in this large study sample.

description: Earthworms are important ecosystem engineers, and assessment of the risk of plant protection products toward them is part of the European environmental risk assessment (ERA). In the current ERA scheme, exposure and effects are represented simplistically and are not well integrated, resulting in uncertainty when the results are applied to ecosystems. Modeling offers a powerful tool to integrate the effects observed in lower tier laboratory studies with the environmental conditions under which exposure is expected in the field. This paper provides a summary of the (In)Field Organism Risk modEling by coupling Soil Exposure and Effect (FORESEE) Workshop held 28â€Ì30 January 2020 in Düsseldorf, Germany. This workshop focused on toxicokineticâ€Ìtoxicodynamic (TKTD) and population modeling of earthworms in the context of ERA. The goal was to bring together scientists from different stakeholder groups to discuss the current state of soil invertebrate modeling and to explore how earthworm modeling could be applied to risk assessments, in particular how the different model outputs can be used in the tiered ERA approach. In support of these goals, the workshop aimed at addressing the requirements and concerns of the different stakeholder groups to support further model development. The modeling approach included 4 submodules to cover the most relevant processes for earthworm risk assessment: environment, behavior (feeding, vertical movement), TKTD, and population. Four workgroups examined different aspects of the model with relevance for risk assessment, earthworm ecology, uptake routes, and crossâ€Ìspecies extrapolation and model testing. Here, we present the perspectives of each workgroup and highlight how the collaborative effort of participants from multidisciplinary backgrounds helped to establish common ground. In addition, we provide a list of recommendations for how earthworm TKTD modeling could address some of the uncertainties in current risk assessments for plant protection products. © 2020 SETAC
Movement interference effects during the tracking of biological and non biological movement

description: Are the neural and behavioural mechanisms underlying the tracking of another human's movement different from that of tracking the movement of a non-biological system? In an experiment by Kilner, Pauligan, Blakemore, (2003) an interference effect was found during the observation and tracking of incongruent biological movements (another human performing a different action), but not so with incongruent nonbiological movements (a robot performing a different action). They defined this interference effect as the degree of change in the movement trajectory of the observer due to observed movement. Recent studies have shown that interference of this kind was subject to both biological and non biological stimuli. However, the question of whether a similar interference effect is present during the observation of movements that possess the same invariant characteristics of human movement such as minimum jerk trajectories with bell-shaped velocity profiles but are not produced by a human (Flash & Hogan, 1985) has not been previously addressed. The present experiment asked eight participants to perform vertical and horizontal movements either congruently or incongruently to novel non-biological movement stimuli sets that resemble human movement (added invariant characteristics) ranging from point light displays to 3D virtual models of humans. This was followed by an interpersonal task while tracking the movements of a human experimenter. Results demonstrated that a congruency effect was observed where incongruent human movements exhibited the most interference. In other conditions, similar congruency effects were observed where the magnitude of the interference was dependent on the biological similarity of the stimuli to actual human movement. Also a main effect of "biologicalness" (Sinusoidal vs. Sinusoidal with noise vs. Minimum Jerk), type (3d human vs. Human) and a main interaction of type and congruency (3d human vs. Human) were observed. We argue that the central nervous system is highly attuned to biological characteristics at the most deep-rooted level. It seems that biological characteristics such as movement optimality leading to the abstract representation of human movement are tightly coupled as they elicit similar interference effects as tracking movements performed by a human.
PR ethics: a simpler (but not simplistic) approach to the complexities

description: Professional public relations bodies internationally have established ethics codes in an attempt to regulate members' ethical behaviour. This paper critiques the code-based framework on philosophical and practical grounds, suggesting that such frameworks are inadequate because they leave practitioners free to interpret these guides in ways that advance their own and their clients' interests. We argue that this latitude does not foster ethical behaviour. We then contrast rule-following, action-based ethics with agent-based ethics, conceived in Aristotelian terms, and suggest that the virtue ethics advanced by Aristotle and his interpreters represents a more challenging but more authentically ethical path for practitioners to consider.
Doing time, doing gender: Hyper-masculinity as a coping strategy among male prisoners

subject: Sociology, Criminology and Penology.
subject: Gender Studies.

description: This thesis assesses the role conceptions of masculinity, more particularly hyper-masculinity play in male prisoners' strategies for coping with the challenges posed by a virtually unisexual prison environment. The study used eight autobiographies by former male prisoners who served sentences in either Canada or the United States in the last forty years. The findings were gathered using a qualitative three-stage coding process and were analyzed using masculinity theories. The results reveal that male prisoners use both hyper-masculine, violent coping strategies and non-violent strategies depending on the circumstances. Critical masculinity theory is better able to explain the violent strategies rather than the non-violent ones. This research is significant because it illuminates the impact of gender on male prisoners' lives and their abilities to cope with imprisonment. The results can be used to inform both treatment and policies regarding male prisoners' incarceration.

description: A sustainable energy supply requires a stepped-up change to renewable sources of energy. By 2050, assuming the demand on the security of supply remains the same, at least 60 percent of the gross final consumption of energy in Germany is to be covered by renewable energy sources. A major challenge is the natural fluctuation in power output, particularly with wind and solar power. In order to guarantee a consistent supply of electrical energy, there are a number of flexibility options available to help balance out the difference between energy supply and demand. In addition to grid expansion, load management and the use of highly flexible conventional power plants, this includes the utilisation of suitable storage methods. Nanotechnology innovations are already contributing to improved energy conversion, storage and transmission. In future, nanotechnology solutions (including the targeted use of nanomaterials) could play a prominent role in the energy sector, especially in the development of innovative approaches to energy storage.

Exploring perceptions of chronic neuropathic pain in spinal cord injured persons
Creators: name: Henwood, Penelope Kathleen
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Health Sciences, Nursing.

description: The purpose of this thesis was to explore the effects of chronic neuropathic pain (CNP) and the process of acceptance of pain as it relates to adjustment to CNP in spinal cord injured (SCI) persons. The participants in two qualitative studies were community-living SCI persons who have CNP. They were currently or had previously received treatment at the out-patient clinic of a regional rehabilitation center. The first study involved a constant comparative analysis of narrative data obtained during three focus groups with 24 SCI persons. The second study involved a grounded theory approach to develop a conceptual framework that describes the process of 'acceptance' of CNP in SCI persons. The data was obtained during in-depth interviews with seven SCI persons with CNP. In Study 1, four interrelated themes emerged that illustrate the multidimensional impact of CNP in SCI. These themes include 'nature of pain', 'coping', 'medication failure', and 'pain impact'. In Study 2, the basic social process to describe acceptance of pain was 'moving forward with pain'.

A psychoanalytic exploration of media exposure to terrorism intrapyschic correlates of adult resilience to the Bali bombing
Creators: name: Curtis, Anne E.
Publisher: name: Swinburne
Year: 2024

description: This thesis explored the utility of psychoanalytic object relations theory as a framework for understanding the intrapsychic processes that predicate adult resilience following exposure in the media to a large-scale terrorist attack. Little, if anything, is known about how people respond to media coverage of a large-scale terrorist attack when they reside in a different country from where a terrorist attack occurred, but their nationality is highly represented in the directly exposed group. The Bali bombing on October 12, 2002 was investigated as an exemplar of this exposure type in the Australian population. More than two thirds of the dead and injured in the bombing were Australian citizens, and the event attracted national grief and mourning (Raphael, 2005).
xPheve: An extensible physics engine for virtual environments

Subjects: subject: Computer Science.

description: Almost any Virtual Reality application requires having a basic set of physical rules and properties such as gravity and collision elasticity. Traditionally, these physical laws were hard-coded within the application, adding an extensive amount of confusing codes that have little to do with the project requirements but more to do with satisfying the basic physics of the scene. Since every VR application would have its own implementation of physical behaviors, we face a problem that is commonly known as the "reinvention of the wheel"! To avoid the redundancy problem and to adequately separate the application components from the low-level physics components, modern programmers use a generic library called physics engine. A physics engine contains within itself all the codes required for dynamic computation of physical behaviors and provides these services to other applications through its application interface (API). There are several commercial physics engines available for programmers. Although they are computationally efficient, they lack a proper architecture. As a result, they face problems with extensibility and maintenance issues. In parallel to the above improvement opportunity, there is another industrial consideration. Sun Microsystems introduced a new technology for constructing portable virtual worlds called Java3D. Since Java3D is new, there are no physics engines available for Java3D programmers. This thesis proposes a new framework for developing virtual environments that obey physical laws. It introduces a new generation of physics engines that are fully customizable and extensible. This is due to a novel architecture that uses a container/plug-in pattern for implementing physical laws and attaching them to the physics engine. The physics engine is named xPheve (Extensible Physics Engine for Virtual Environments) and its current implemented is in Java and on top of Java3D libraries.

description: Both delayed study entry (left‐truncation) and competing risks are common phenomena in observational time‐to‐event studies. For example, in studies conducted by Teratology Information Services (TIS) on adverse drug reactions during pregnancy, the natural time scale is gestational age, but women enter the study after time origin and upon contact with the service. Competing risks are present, because an elective termination may be precluded by a spontaneous abortion. If left‐truncation is entirely random, the Aalen‐Johansen estimator is the canonical estimator of the cumulative incidence functions of the competing events. If the assumption of random left‐truncation is in doubt, we propose a new semiparametric estimator of the cumulative incidence function. The dependence between entry time and time‐to‐event is modeled using a cause‐specific Cox proportional hazards model and the marginal (unconditional) estimates are derived via inverse probability weighting arguments. We apply the new estimator to data about coumarin usage during pregnancy. Here, the concern is that the cause‐specific hazard of experiencing an induced abortion may depend on the time when seeking advice by a TIS, which also is the time of left‐truncation or study entry. While the aims of counseling by a TIS are to reduce the rate of elective terminations based on irrational overestimation of drug risks and to lead to better and safer medical treatment of maternal disease, it is conceivable that women considering an induced abortion are more likely to seek counseling. The new estimator is also evaluated in extensive simulation studies and found preferable compared to the Aalen‐Johansen estimator in non–misspecified scenarios and to at least provide for a sensitivity analysis otherwise.
Molecular mechanisms for IL-10 induced CD14 expression in human monocytic cells

Year: 2004
Subjects: subject: Health Sciences, Immunology.

description: IL-10, an immunoregulatory cytokine with biological effects primarily on inhibition of inflammatory responses, has also been shown to stimulate a variety of functions including CD14 expression on human monocytic cells. CD14, a receptor for lipopolysaccharide (LPS), plays a critical role in the synthesis of proinflammatory cytokines by LPS-stimulated monocytic cells. Herein, I show that LPS-induced CD14 expression on monocytic cells may be mediated by endogenously produced IL-10. In this study, I have investigated the molecular mechanisms by which IL-10 enhances CD14 expression in normal human monocytes and a promyelocytic HL-60 cells as a model system. IL-10 induced the phosphorylation of PI3K and p42/44 extracellular signal-regulated kinase (ERK) MAPKs. By employing specific inhibitors for PI3K (LY294002) and ERK MAPKs (PD98059), I provide evidence that LY294002 either alone or in conjunction with PD98059 inhibited IL-10-induced phosphorylation of STAT1 and consequently CD14 expression. However; IL-10-induced STAT3 activation remained unaffected under these conditions. Furthermore, LY294002 and PD98059 inhibited the binding of STAT1 transcription factor to its binding site in the CD14 promoter. Finally, STAT1 siRNA inhibited IL-10-induced CD14 expression. Taken together, results show for the first time that IL-10-mediated CD14 upregulation may be mediated by STATI activation independently of STAT3. Furthermore, IL-10-activated STAT1 may be regulated through PI3K either alone or in concert with the ERK MAPKs.

description: Binary and ternary vapor-liquid equilibrium data were determined at 75°C for the mixture of benzene, n-heptane and n-propyl alcohol using a modified Gillespie type of still. The equilibrium data for the three binary and the ternary systems are considered to be thermodynamically consistent as shown from the consistency test. Correlating the data with the Redlich-Kister equations for the binary and ternary systems shows that these equations would represent the data accurately over the entire range of compositions. The experimental results indicate that two binary systems, namely, n-heptane-n-propyl alcohol and n-propyl alcohol-benzene form an azeotrope at 75°C. Nevertheless no ternary azeotrope is found from the experiment.

description: The core focus for this research project is to analyze what alternative university based venture based funding mechanisms are currently being used to promote entrepreneurship and regional development, who is managing those funds, what returns are expected, and outcomes of the investments. The research project is intended to provide a benchmark for universities considering financing options for entrepreneurial development. The questions on size, type, qualifications, management, purpose, management and results are all intended to help in the decision making process. The underlying belief is that a venture fund should somehow help accomplish the universities overarching goals. These goals typically include: Educating students; Promoting research/knowledge acquisition; Enhancing economic development; Creating opportunities for students and faculty; Identification of sustainable resources; and Community outreach. The development of venture funds (of whatever type) is seen as a possible alternative method to achieve any or all of these core university goals and the research will tell us the prevailing views of a broad mix of universities.
Distinct roles of Gi/o protein subunits in signaling by dopamine D2S receptors in rat pituitary adenoma cells.

description: In GH4ZR7 lactotroph cells dopamine-D2S receptor activation inhibited forskolin-induced cAMP production, BayK8644-activated calcium influx, basal B-raf kinase and blocked TRH-mediated c-Raf activity, phosphorylation of MEK 1/2 and p42/44-MAPK. These actions were blocked by pretreatment with PTX, indicating mediation by Gi/o proteins. Following PTX treatment, D2S receptor signaling was rescued in cells stably transfected with individual PTX-insensitive Galpha mutants. Inhibition of adenylyl cyclase (AC) was partly rescued by Galphai2 or Galphai3. By contrast, Galphao alone completely reconstituted D2S-mediated inhibition of L-type calcium channels. Galphao and Galphai3 mediated D2S inhibition of p42/44-MAPK. In cells transfected with GRK-carboxylterminal domain to inhibit Gbetagamma signaling, only D2S-mediated inhibition of calcium influx was blocked, but not inhibition of adenylyl cyclase or MAPK. These results indicate that the dopamine-D2S receptor couples to distinct Gi/o proteins depending on the pathway addressed, and suggest a novel Galphai3/Galphao-dependent inhibition of MAPK that is independent of Gbetagamma signaling.

description: Heart transplantation patients generally demonstrate exercise capacities that are below the minimal standards for firefighting. Therefore, it is unlikely that heart transplantation patients will receive medical and/or employer clearance for active duty. We report a case of a firefighter who sought to return to full-time active duty following heart transplantation. We examined his physiological readiness to return to work during occupation-specific testing. Remarkably, the patient was able to meet the minimal requirements for full active firefighting. This finding provides direct evidence to support the potential of transplant patients returning to active duty in physiologically demanding occupations.

description: Cancer stem cells (CSCs) are defined as a subpopulation of “stem”-like cells within the tumor with unique characteristics that allow them to maintain tumor growth, escape standard anti-tumor therapies and drive subsequent repopulation of the tumor. This is the result of their intrinsic “stem”-like features and the strong driving influence of the CSC niche, a subcompartment within the tumor microenvironment that includes a diverse group of cells focused on maintaining and supporting the CSC. CXCL12 is a chemokine that plays a crucial role in hematopoietic stem cell support and has been extensively reported to be involved in several cancer-related processes. In this review, we will provide the latest evidence about the interactions between CSC niche-derived CXCL12 and its receptors—CXCR4 and CXCR7—present on CSC populations across different tumor entities. The interactions facilitated by CXCL12/CXCR4/CXCR7 axes seem to be strongly linked to CSC “stem”-like features, tumor progression, and metastasis promotion. Altogether, this suggests a role for CXCL12 and its receptors in the maintenance of CSCs and the components of their niche. Moreover, we will also provide an update of the therapeutic options being currently tested to disrupt the CXCL12 axes in order to target, directly or indirectly, the CSC subpopulation.

description: Prognosis for diffuse intrinsic pontine glioma (DIPG) and generally for diffuse midline gliomas (DMG) has only marginally improved over the last ~40 years despite dozens of chemotherapy and other therapeutic trials. The prognosis remains invariably fatal. We present here the rationale for a planned study of adding 5-aminolevulinic acid (5-ALA) to the current irradiation of DIPG or DMG: the 5aai regimen. In a series of recent papers, oral 5-ALA was shown to enhance standard therapeutic ionizing irradiation. 5-ALA is currently used in glioblastoma surgery to enable demarcation of overt tumor margins by virtue of selective uptake of 5-ALA by neoplastic cells and selective conversion to protoporphyrin IX (PpIX), which fluoresces after excitation by 410 nm (blue) light. 5-ALA is also useful in treating glioblastomas by virtue of PpIX’s transfer of energy to O2 molecules, producing a singlet oxygen that in turn oxidizes intracellular DNA, lipids, and proteins, resulting in selective malignant cell cytotoxicity. This is called photodynamic treatment (PDT). Shallow penetration of light required for PpIX excitation and resultant energy transfer to O2 and cytotoxicity results in the inaccessibility of central structures like the pons or thalamus to sufficient light. The recent demonstration that keV and MeV photons can also excite PpIX and generate singlet O2 allows for reconsideration of 5-ALA PDT for treating DMG and DIPG. 5-ALA has an eminently benign side effect profile in adults and children. A pilot study in DIPG/DMG of slow uptitration of 5-ALA prior to each standard irradiation session—the 5aai regimen—is warranted.

description: Die Arbeit analysiert mit Hilfe eines systemischen Ursache-Wirkungsmodells einen umfangreichen Gesamtzusammenhang der verschiedenen Aspekte und Dimensionen vonNachhaltigkeit. Ausgangspunkt des zugrundeliegenden Modells ist die Frage "Wovon hängt eine nachhaltige Gesellschaft ab?" Hierzu wurden verschiedene Experten und Akteure aus Wirtschaft, Verbraucher, Medien und Politik systematisch eingeladen, ihre Sichtweise einzubringen. Damit gelingt es, unterschiedliche Sichtweisen und Ansichten gemeinsam abzubilden und zudem auch jeweils nach dem WARUM einzelner Wirkungen zu fragen. So steht nun am Ende ein Erklärungsmodell zu den möglichen Hebeln und den tatsächlichen Hindernissen für eine nachhaltige Gesellschaft, welches über viele aktuell vorliegende, rein beschreibende Arbeiten hinausgeht.

description: Die Studie verfolgte das Ziel, einen Überblick über den Stand des Umweltbewusstseins, die Verhaltensbereitschaften der Menschen im Alltag sowie die Akzeptanz der Umweltpolitik hinsichtlich aktueller umwelt- und nachhaltigkeitsbezogener Politik- und Themenfelder zu geben. Hierzu werden wesentliche Veränderungen im Zeitverlauf beschrieben und das spezifische Umweltbewusstsein und -verhalten von Befragten in unterschiedlichen sozialen Milieus untersucht. Im Zentrum des neuen Schwerpunktes steht das alltägliche Handeln mit seinem Potenzial, sich innovativ auf die Anforderungen nachhaltiger Entwicklung einzustellen. Es geht um die Frage, welche Anknüpfungspunkte sich für nachhaltige Lebensweisen im Alltag der Menschen finden lassen. Untersucht wird diese Frage für die Handlungsfelder Mobilität, Lebensmitteleinkauf, Haushaltsführung/größere Anschaffungen sowie Wohnen/Wohnumfeld. Methodisch stand bei der Studie eine Repräsentativumfrage für Deutschland im Jahr 2012 im Mittelpunkt, die durch Gruppendiskussionen, Experteninterviews und eine Medienanalyse zur Rio+20-Konferenz ergänzt wurde.
p-p plots and precedence tests for planar point processes

description: Let X1, X2,..., Xn be a random sample of size n from a continuous distribution F and Y1 , Y2,...,Ym be a random sample of size m from a continuous distribution G. One of the ways to test the hypothesis of equality of F and G against the alternative that F < G when both distributions are univariate is to perform a precedence test -a test that not only requires only a portion of the samples, but which is distribution-free under the null hypothesis. The initial purpose of this thesis was to extend the notion of a precedence test to higher dimensions. In doing so, we found two different tests that are appropriate for both partial and complete data sets. These tests are based on two different extensions of the usual definition of a procentile-procentile plot -which is closely related to the precedence test statistic on the line- to the plane. The first of the above mentioned extensions involves the contours formed by the distribution function F; the second of our tests uses the marginal quartiles of F. For both extensions of the empirical p -- p plot, we have proven a Glivenko-Cantelli type of result. Also, we have developed their asymptotic convergence to Gaussian limits. The choice between tests based on these two plots depends on the kind of information that the data of our experiment generates. All the results presented here, although mostly presented for R2 , are valid for ℜd -valued data.

description: n recent years, the energy production sector has experienced a growing interest in new energy vectors enabling energy storage and, at the same time, intersectoral energy applications among users. Hydrogen is one of the most promising energy storage and carrier media featuring a very high gravimetric energy density, but a rather low volumetric energy density. To this regard, this study focuses on the use of aluminum as energy storage and carrier medium, offering high volumetric energy density (23.5 kWh L−1), ease to transport and stock (e.g., as ingots), and is neither toxic nor dangerous when stored. In addition, mature production and recycling technologies exist for aluminum. Herein, the performance of power systems driven by aluminum powder in terms of electrical efficiency (η(I)) and round-trip efficiency (RTE) is analyzed. Along with the additional advantages relating to high volumetric energy density, and safety and management aspects, the aluminum-based technology appears to outperform the power-to-power systems based on hydrogen and liquid fuels.

Searches for radio transients

description: Exploration of the transient Universe is an exciting and fast-emerging area within radio astronomy. Known transient phenomena range in time scales from subnanoseconds to years or longer, thus spanning a huge range in time domain and hinting a rich diversity in their underlying physical processes. Transient phenomena are likely locations of explosive or dynamic events and they offer tremendous potential to uncover new physics and astrophysics. A number of upcoming next-generation radio facilities and recent advances in computing and instrumentation have provided a much needed impetus for this field which has remained a relatively uncharted territory for the past several decades. In this paper we focus mainly on the class of phenomena that occur on very short time scales (i.e. from ~milliseconds to ~nanoseconds), known as fast transients, the detections of which involve considerable signal processing and data management challenges, given the high time and frequency resolutions required in their explorations, the role of propagation effects to be considered and a multitude of deleterious effects due to radio frequency interference. We will describe the techniques, strategies and challenges involved in their detections and review the world-wide efforts currently under way, both through scientific discoveries enabled by the ongoing large-scale surveys at Parkes and Arecibo, as well as technical developments involving the exploratory use of multi-element array instruments such as VLBA and GMRT. Such developments will undoubtedly provide valuable inputs as next-generation arrays such as LOFAR and ASKAP are designed and commissioned. With their wider fields of view and higher sensitivities, these instruments, and eventually the SKA, hold great potential to revolutionise this relatively nascent field, thereby opening up exciting new science avenues in astrophysics.

description: A generation of young people in Canada has grown up in the face of the so-called "War on Terror". Where previous generations have confronted the Cold War or the World Wars, this is the war that has shaped today's young people's narratives of collective memory. My study investigates the following research questions: How young people in Canada understand "the War on Terror"? How they see "the War on Terror" affecting their lives and their constructions of imagined communities (Anderson, 1983)? How they make collective memories of "the War on Terror" based on these understandings? I collect my data in the form of written narratives, follow-up interviews, and demographic questionnaires. Building on theoretical models from the field of collective memory studies (Halbwachs, 1980; Wertsch, 2002), nationalism studies (Anderson, 1983; Billig, 1995), and cultural representations (Said, 1980; Hall, 1980, 1997, 2000, 2002), I explore the understandings, representations and experiences of young people in the form of the collective memories of "the War on Terror". I find that the terrain of collective memory is like the topography. This topography has three main features: human agents, technologies of memory (Wertsch, 2002) and different social groups or communities. My participants construct collective memories through processes that involve a collectivity of significant 'others', including parents and teachers, or what I call 'interpretative communities'. Significantly, the hegemonic narrative, according to the participants of my study, is not the official Canadian government's narrative of "the War on Terror", rather my participants reject the image of Canada as a military nation in favor of that of a multicultural peaceful nation. I also find that "the War on Terror" has personally affected the young Canadian Muslim participants of this study in ways that it has not the non-Muslim participants.
