Broadband facts, fiction and urban myths
Creators: name: Tucker, Rodney S.
Publisher: name: Swinburne
Year: 2024

description: There has been a lively debate surrounding the Australian Governments plan to build a fibre-based National Broadband Network. Unfortunately, a variety of urban myths about the NBN have evolved and spread over the past 12 months. Some of these myths are based on misunderstandings of the capabilities and limitations of broadband technology and some are out of alignment with experience in countries where broadband access is more advanced than in Australia. The objective of this article is to correct some of these misconceptions, to debunk some of the more common urban myths and to provide some basic facts for the lay person on the capabilities and limitations of various broadband technologies.

description: The recent influx of retail investors into the stock market raises concerns about how best to protect and inform these investors as well as questions on the broader impact of financial democratization. Using retail brokerage website outages as a negative shock to retail investor activity, I find that lower retail trading causes underreaction to earnings news, particularly in firms with high retail ownership. This evidence is consistent with retail investors acting as informed participants who contribute to efficient price discovery, especially for firms with less institutional support. In addition, I find significant heterogeneity in the sophistication of retail investors based on their brokerage of choice. I find less change in market reaction to earnings news when retail investors using less established brokerages experience an outage, indicating that retail investors on these platforms are less informed than their counterparts on more established brokerages. In aggregate, my results suggest that retail investors play an important role as informed investors who aid in price discovery after earnings announcements.

description: Arctic tundra ecosystems exhibit small-scale variations in species composition, micro-topography as well as significant spatial and temporal variations in moisture. These attributes result in similar spectral characteristics between distinct vegetation communities. In this study we examine spectral variability at three phenological phases of leaf-out, maximum canopy, and senescence of ground-based spectroscopy, as well as a simulated Environmental Mapping and Analysis Program (EnMAP) and simulated Sentinel-2 reflectance spectra, from five dominant low-Arctic tundra vegetation communities in the Toolik Lake Research Area, Alaska, in order to inform spectral differentiation and subsequent vegetation classification at both the ground and satellite scale. We used the InStability Index (ISI), a ratio of between endmember and within endmember variability, to determine the most discriminative phenophase and wavelength regions for identification of each vegetation community. Our results show that the senescent phase was the most discriminative phenophase for the identification of the majority of communities when using both ground-based and simulated EnMAP reflectance spectra. Maximum canopy was the most discriminative phenophase for the majority of simulated Sentinel-2 reflectance data. As with previous ground-based spectral characterization of Alaskan low-Arctic tundra, the blue, red, and red-edge parts of the spectrum were most discriminative for all three reflectance datasets. Differences in vegetation colour driven by pigment dynamics appear to be the optimal areas of the spectrum for differentiation using high spectral resolution field spectroscopy and simulated hyperspectral EnMAP and multispectral Sentinel-2 reflectance spectra. The phenological aspect of this study highlights the potential exploitation of more extreme colour differences in vegetation observed during senescence when hyperspectral data is available. The results provide insight into both the community and seasonal dynamics of spectral variability to better understand and interpret currently used broadband vegetation indices and also for improved spectral unmixing of hyperspectral aerial and satellite data which is useful for a wide range of applications from fine-scale monitoring of shifting vegetation composition to the identification of vegetation vigor.

description: Small non-coding RNAs play a key role in many physiological and pathological processes. Since 2004, miRNA sequences have been catalogued in miRBase, which is currently in its 21st version. We investigated sequence and structural features of miRNAs annotated in the miRBase and compared them between different versions of this reference database. We have identified that the two most recent releases (v20 and v21) are influenced by next-generation sequencing based miRNA predictions and show significant deviation from miRNAs discovered prior to the high-throughput profiling period. From the analysis of miRBase, we derived a set of key characteristics to predict new miRNAs and applied the implemented algorithm to evaluate novel blood-borne miRNA candidates. We carried out 705 individual whole miRNA sequencings of blood cells and collected a total of 9.7 billion reads. Using miRDeep2 we initially predicted 1452 potentially novel miRNAs. After excluding false positives, 518 candidates remained. These novel candidates were ranked according to their distance to the features in the early miRBase versions allowing for an easier selection of a subset of putative miRNAs for validation. Selected candidates were successfully validated by qRT-PCR and northern blotting. In addition, we implemented a web-server for ranking potential miRNA candidates, which is available at: www.ccb.uni-saarland.de/novomirank.

description: In 1985 Hull was declared the Capital of Crime. Hull had won Quebec's unenviable title of having the highest crime rate in the province for 1984. The two dailies in the region, Le Droit (French) and The Citizen (English) closely followed the search for what was happening in the otherwise peaceful "village." The reason was simple: the concentration of bars on la promenade du Portage. The Street had been completely remodelled in the seventies by the federal government; in order to re-launch Hull's downtown core, several bars had converged on the old Main Street. La promenade's criminality and its cleanup was the subject of a large amount of newspaper articles. In this thesis I compare the ways in which the two newspapers covered the Street and the events which surrounded it. I do this at different levels: as a careful reader, through quantitative content analysis and through discourse analysis. The results show that the newspaper use very different perspectives from which to write about the same place. These perspectives help us to understand the fundamental differences in the way each community thinks the bar Strip and what it represents. The representations of this contested street inform the way the communities understand each another as well as themselves. Cultural geography is preoccupied with representations; it is through these that we learn to recognize ourselves and to recognize our place within society as well as within place. The Strip was covered in such a way as to help configure the myth that surrounds it. By using stereotypes and recurrent images, the newspapers increased the mystique and the myth of the place. In this thesis, I explore the links between place, media and representation.

description: The relationship between the sensitivity of microtubules (Mts) to MeHg-induced disassembly and the extent apoptosis was examined in undifferentiated and neuronally differentiated P19 cells. The extent of Mt disassembly was examined qualitatively by immunofluorescence microscopy and quantitatively by polymer and soluble protein extractions, followed by dot blotting or by SDS-PAGE and western blotting. In both undifferentiated and neuronally differentiated P19 cells MeHg treatments disassembled Mts in a time- and dose-dependent manner, as assessed by immunofluorescence microscopy. However, when the extent of Mt disassembly was assessed by quantitative dot blotting or by SDS-PAGE followed by western blotting there was no change observed in the amount of tubulin in the polymer and soluble fractions between control and MeHg-treated samples. These data suggest that MeHg treatments disassemble Mts into a form which is not extractable as soluble protein. MeHg-induced apoptosis was assessed using a combination of assays including single cell gel electrophoresis (Comet assay), TUNEL, conventional agarose gel electrophoresis, and pulsed field gel electrophoresis.

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis addresses the emerging field of mobile agents. The mobile agent communication paradigm is viewed as the extension of the client/server communication model. Mobile agents are self-contained objects that travel autonomously in a computer network, executing on different machines until their assigned task is solved. Mobile agents offer many advantages over the client/server model such as asynchronous operation and support for mobile users and lightweight devices but also new issues and challenges such as security and privacy. A multimedia mobile agent system is designed and implemented to asynchronously execute tasks on behalf of the user. The mobile agent system is composed of a multimedia agent platform and agent-based applications. The agent platform provides a migration facilitator, an agent execution environment, an agent transport protocol and a simple API to the basic agent operations such as build and jump. The agent-based applications are built on top of the agent platform and offer asycnchronous services such as search, retrieve and send multimedia documents. (Abstract shortened by UMI.)

description: This Interpretative Phenomenological Analysis (IPA) study aims to understand the lived experience of older adults who survived a COVID-19 hospitalization during the first year of the pandemic. COVID-19 is a topic of great concern and relevance for older adults. The COVID-19 experiences of older adults are particularly valuable as older adults have been extremely disproportionately impacted by COVID-19 morbidity and mortality. This study recruited older adults living in Iowa who were English speaking, age 50 and older, having at least one overnight stay in a hospital due to COVID-19 during the first year of the pandemic. In-depth, semi- structured interviews were conducted via Zoom. Interviews were transcribed verbatim and coded according to IPA methodological standards. Case and cross-case IPA data analysis informed three major group experiential themes (GETs). Participants describe navigating the ever-changing landscape of the American healthcare system during the global health crisis. Through their experiences readers get an understanding of the severity of the situation, the perceptions of the healthcare received, and the short and long-term impacts on the older adults’ personal identity. These overarching themes significantly add to our understanding of older adults’ lived experience of a COVID-19 hospitalization and surviving a major health crisis. Implications for social work practice and future research are discussed.

description: Feminism in Islam has received increased scrutiny in the last three decades (Ali et al., 2017) as the visibility and attention to Muslim women’s issues have increased. This examination is particularly important for Muslim women in the current political climate. The purpose of this study is to examine the overarching themes of online comments in response to an article discussing journalist Noor Tagouri’s argument for Muslim women’s freedom of choice to dress modestly in hopes to better understand people’s conceptions of Muslim women. This study employs an intersectional feminist lens, uncovering overlapping Islamophobia and misogyny that some Muslim women may experience. This research will provide further insight into people’s perceptions of Muslim women in their own words without consequence of personal identifiers. The results provide valuable information for psychologists working with Muslim women so they may broaden their understanding of the dialogues and attitudes their clients receive in a Western environment. Considering the increasing Islamophobia and xenophobia in the Western world (Council on American-Islamic Relations, 2008) and the historical and present day political issues regarding the policing of women’s bodies (Chesney-Lind, 2017), the intersectional experiences of Muslim women are particularly critical to understand.
Central mechanisms of pain transmission

description: Chronic pain, broadly classified as inflammatory (caused by tissue damage) or neuropathic (caused by nerve damage), affects approximately 100 million Americans and only a minority of patients experience satisfactory pain relief with currently available pharmaceutics. The immune system plays a critical role in the pathogenesis of acute and chronic pain triggered by injury or illness. Here, I examine how the complement system, a principal component of the innate immune system affects pain signaling in the spinal cord. This is based on the accumulating evidence that complement, and particularly C5a/C5aR1 signaling, are important in the development and maintenance of neuropathic pain. Using a mouse model of neuropathic pain, I found that C5a signals via its receptor C5aR1 after injury, and that blockade of this signal can promote analgesia for mechanical hyperalgesia but not for cold allodynia. Furthermore, I found that microglia are responsible, in part, for this signaling by using a selective microglia knockout of C5aR1, and by demonstrating that microglia have clear cellular responses to C5a via C5aR1. I also evaluate the impact of C5a on projection neurons in the spinal dorsal horn and how nerve injury affects calcium signaling in the central terminals of the primary afferents.
description: Additionally, I examined how neuronal signaling changes with sensory perception altering decision making and motor movement, since one of the primary complaints of people with chronic pain is in how it can make them fearful to move affected limbs due to a fear of pain with movement. I found that mice demonstrate a clear preference for walking on innocuous tactile surfaces and that neuronal signals change based on sensation and motor movement.
description: In conclusion, I have demonstrated that C5a/C5aR1 signaling plays a critical role in the development and maintenance of chronic neuropathic pain in the spinal dorsal horn. I have also developed a method to integrate behavior and imaging in the context of pain while uncovering how a previously understudied brain region is impacted by both sensory qualities and motor movement.
Plastic interaction relations for hollow structural steel sections.

Subjects: subject: Engineering, Civil.

description: The first part of this study reports an experimental program consisting of six full-scale tests on pipe sections under load combinations of shearing forces, bending moments, and twisting moments. The experimental results agree very well with the predicted failure loads based on recently developed interaction relations. The experimental program establishes the validity of the analytical techniques used to derive the interaction relations for pipe sections. The verified methodology is extended to derive interaction relations for square hollow structural sections under combinations of normal forces, twisting moments, biaxial bending moments, and biaxial shearing forces. Careful consideration is given to the applicability limits of the developed interaction relations. A stress resultant transformation scheme is devised in order to reduce the number of interaction relations from 20 cases to only three fundamental cases.
Importing the revolution: The image of America in French-Canadian political discourse, 1805-1837.
Creators: name: Harvey, Louis-Georges.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: American Studies.

description: Between 1805 and 1837, the image of America assumed very different meanings within French-Canadian political discourse. America, which had appeared as a globally negative model before 1815, came in the 1830's to serve as an inspiration for the establishment of a French-Canadian republic, resistance to colonial rule and eventually the necessity of rebellion against that rule. Essentially though, these changes were effected within the same pattern of political discourse, one emphasizing the continuing conflict between the forces of virtue and corruption. Indeed, it is this very pattern which can explain the prominent place of the American image. Once virtue was associated with North America and corruption with Europe, no other political image could acquire the meaning which was ultimately associated with that of the United States. The failure of the Rebellions and the survival of the French-Canadian identity under British rule should not obscure this important stage in the development of French-Canadian political discourse.
Detection of in vitro vertical root fractures with and without a metal artifact reduction algorithm.
Creators: name: Bisnett, Derrick
Publisher: name: University of Iowa
Year: 2025
Subjects: public abstract

description: Introduction: Vertical root fractures are a diagnostic challenge due to their non-specific clinical symptoms, small size, and slow progression. The clinical situation is made more complex as they often occur in endodontically treated teeth. Both clinical symptoms and radiographic findings are important for the diagnosis of vertical root fractures. Cone beam computed tomography (CBCT) is recommended for diagnosis when two-dimensional imaging is inconclusive. Although CBCT has many advantages over two-dimensional imaging, there can be artifacts in the scans when there are high density materials such as gutta-percha or metal in the scan. These high-density materials are often found within endodontically treated teeth in which vertical root fractures occur. Many techniques have been proposed to reduce the metal artifacts present in these scans. Several CBCT manufacturers have produced proprietary post-processing algorithms, yet very little is known about their efficacy. To date, no study has evaluated the Carestream 9600 (Carestream Dental LLC, Atlanta Georgia) metal artifact reduction algorithm in the evaluation of vertical root fractures.
description: Materials and Methods: Vertical root fractures were induced in 50 teeth and backfilled with gutta-percha while 50 control teeth were endodontically treated without vertical root fractures. Three clinical scenarios were used to assess how both intracanal artifacts and extracanal artifacts are influenced by the metal artifact reduction algorithm. Three hundred randomized and anonymized scans were evaluated independently by two calibrated oral and maxillofacial radiology residents. Half of the scans had metal artifact reduction algorithm while the other half did not. Cohen’s Kappa was calculated for inter-rater reliability, intra-rater reliability, and the gold standard.
description: Results: Intra-rater reliability ranged from substantial to slight for one viewer and moderate to slight for the other viewer. Inter-rater reliability ranged from moderate to poor. Both viewers ranged from moderate to poor when compared to the gold standard.
description: Conclusion: There is no difference in the accuracy of detecting a vertical root fracture with and without a metal artifact reduction algorithm using a Carestream 9600 (Carestream Dental LLC, Atlanta Georgia).
The effects of modulating potassium(ATP) channel activity in normal and 1-week denervated mouse EDL and soleus muscles.

description: During exercise, the metabolic rate of muscle increases considerably, and hence the concentration of various metabolites is altered. Surprisingly, the concentration of ATP is not decreased significantly even at exhaustion. This suggests that the muscle may have a safety mechanism that shuts down force generation in order to avoid energy depletion, as the latter causes irreversible damage to the muscle cell. The K+(ATP) channel, which is activated by decreased ATP levels, might be involved in this safety mechanism. According to its postulated mechanism, once activated the channel can contribute to decreasing force generation by decreasing the excitability of the muscle membrane. The scope of this thesis will deal with the physiological role of the K+(ATP) channel in skeletal muscle during fatigue. The main objectives of this study were to understand the physiological role of the K+(ATP) channel and how this role is affected by 1-week denervation in mouse EDL and soleus muscles. K +(ATP) channels were either blocked with 10 muM glibenclamide, or activated with 100 muM pinacidil, while muscles were fatigued by tetanic contractions every sec for 3 min.

description: The objective of this research was to broadly study the topic of non-equity strategic alliances in the high technology sector. The a priori assumptions were that non-equity alliances were different, and that treatment of non-equity alliances in high technology firms was different from other industries. The objectives of the study were to understand: (a) why are non-equity alliances chosen in the high technology sector; (b) what roles do strategy and core competencies play in the choice of non-equity alliances; and (c) what role do technology and market factors play in high technology alliances? This study investigated twelve alliance formation decisions among three firms in the Ottawa-Carleton Region, in Ontario, Canada. The firms in the sample ranged in size from $150 million in annual revenues, to more than \$10 billion. The partner organizations reflected an international scope with headquarters in Japan, Europe and North America. The sample covered non-equity strategic alliances formed from 1990 to 1996.

description: Intact melanocortin signaling via the G protein-coupled receptors (GPCRs), melanocortin receptor 4 (MC4R), and melanocortin receptor 3 (MC3R) is crucial for body weight maintenance. So far, no connection between melanocortin signaling and hypothalamic inflammation has been reported. Using a bimolecular fluorescence complementation library screen, we identified a new interaction partner for these receptors, ring finger protein 11 (RNF11). RNF11 participates in the constitution of the A20 complex that is involved in reduction of tumor necrosis factor α (TNFα)-induced NFκB signaling, an important pathway in hypothalamic inflammation. Mice treated with high-fat diet (HFD) for 3 days demonstrated a trend toward an increase in hypothalamic Rnf11 expression, as shown for other inflammatory markers under HFD. Furthermore, Gs-mediated signaling of MC3/4R was demonstrated to be strongly reduced to 20–40% by co-expression of RNF11 despite unchanged total receptor expression. Cell surface expression was not affected for MC3R but resulted in a significant reduction of MC4R to 61% by co-expression with RNF11. Mechanisms linking HFD, inflammation, and metabolism remain partially understood. In this study, a new axis between signaling of specific body weight regulating GPCRs and factors involved in hypothalamic inflammation is suggested.

description: The nucleolus is a non-membrane bound organelle within the nucleus that is the center for ribosome biogenesis. It has three identifiable, phase-separated subdomains: the fibrillar center, the dense fibrillar component, and the granular component. These domains host the canonical domain markers RNA Polymerase I, Fibrillarin, and Npm1, respectively. Most of what we know about the phase separation of the nucleolus is based on studies using these canonical domain markers, however, they are only three of the hundreds of proteins involved in ribosome biogenesis, many of which are suspected of phase separation. Using Xenopus laevis oocyte nucleoli, a system particularly advantageous due to large nucleolar size, I mapped the domain localization of numerous nucleolar proteins suspected of phase separation. I used these proteins to observe nucleolar morphology under conditions that inhibit ribosome biogenesis and to probe phases of aggregation. I also investigated properties of proteins that contribute to domain localization by examining the contribution of intrinsically disordered regions and binding as part of a multi-component complex.
description: This thesis provides a more nuanced model of the nucleolus. It supports a model for phase separation and grouping of proteins involved in temporally-sequential events of ribosome biogenesis. It provides evidence that borders between nucleolar domains are less fixed for some proteins compared to others, and that domain morphology is affected under conditions that inhibit ribosome biogenesis. I show that a single set of rules with respect to the role of intrinsically disordered regions in phase separation does not apply when comparing nucleoli to other condensates. I also show that protein complex binding plays an important role in correct domain localization for some nucleolar proteins. Specifically, correct dense fibrillar component localization for members of the box H/ACA pseudouridylation complex depends on their ability to bind to the complex. My findings led me to conclude phase separation and compartmentalization in the nucleolus is best thought of as shifts in concentration equilibrium.

description: Cognates are words in different languages that have similar spelling and meaning. They can help second-language learners with vocabulary expansion and reading comprehension tasks. Special attention needs to be paid to pairs of words that appear similar but are in fact false friends: they have different meanings in all contexts. Partial cognates are pairs of words in two languages that have the same meaning in some, but not all, contexts. Detecting the actual meaning of a partial cognate in context can be useful for Machine Translation and Computer-Assisted Language Learning tools. Our research on cognate and false-friend words between two pair of languages (French and English in our case) consists in automatically classifying a pair of words from two languages as cognates or false friends. We use Machine Learning techniques with several measures of orthographic similarity as features for classification. We study the impact of selecting different features, averaging them, and combining them through Machine Learning techniques. The methods work on different pair of languages as long as a small amount of annotated pairs of words is provided as training data. In addition to the work done on cognate and false-friend identification we propose a supervised and a semi-supervised method that uses bootstrapping for disambiguating partial cognates between French and English. The proposed methods use only automatically-labeled data and therefore they can be applied to other pairs of languages as well. The data that we use is automatically collected from parallel corpora. The impact of data collected from different domains is also taken into account in our research. To complement the studies that we did on cognates, false friends and partial cognate pairs of words, we developed an annotation tool for this special type of words. The tool can automatically annotate cognates, false friends and partial cognates for any French text. The tool uses UIMA (Unstructured Information Management Architecture) from IBM and BaLIE (an open-source Java project designed to extract information from free text).

description: Cette recherche s'intéresse au programme "Fonds Mémoire canadienne" du ministère du Patrimoine canadien par le biais des dossiers numériques à portée éducative mis en ligne par Les Archives de Radio-Canada/CBC Archives. Elle vise à observer (a) comment ces dossiers numériques sont employés en classe et (b) de quelle manière et dans quelle mesure l'utilisation de ce matériel a pu laisser des traces sur l'identité culturelle et la conscience historique des élèves de niveau secondaire. Les résultats de cette recherche, réalisée à Ottawa-Gatineau, à Terrebonne ainsi qu'à Montréal, démontrent que le matériel est largement méconnu en milieu scolaire. Dans les classes observées, les archives de Radio-Canada ne font pas partie des ressources pédagogiques utilisées, ce qui limite considérablement leur portée sur la conscience historique et l'identité nationale des élèves.
Expression of the interleukin-7 receptor alpha-chain is down regulated on CD4 T-cells by the HIV-1 Tat protien

description: HIV infection elicits defects in CD4 T-cell homeostasis in both a quantitative and qualitative manner. Interleukin-7 (IL-7) is essential to T-cell homeostasis and several groups have shown reduced levels of the IL-7 receptor alpha-chain (CD127) on both CD4 and CD8 T-cells in viremic HIV+ patients. Our lab has demonstrated that soluble HIV Tat protein specifically down regulates cell surface expression of CD127 on human CD8 T-cells. Once taken up by CD8 T-cells, Tat enters the cytoplasm and interacts directly with the cytosolic tail of CD 127 inducing receptor capping, endocytosis and degradation. The purpose of this study is to determine if, similar to CD8 T-cells, HIV Tat down regulates surface CD127 expression on CD4 T-cells and if this down regulation affects IL-7 signaling. To investigate this, primary CD4 T-cells isolated from healthy HIV-negative volunteers were incubated in medium alone or with Tat protein (10 ug/ml) for up to 72 hours and then analyzed by flow cytometry. As anticipated, soluble HIV Tat protein induces a significant decrease in surface CD127 expression on CD4 T-cells relative to cells cultured in medium alone. The effect was dose and time dependent, reversible, and could be blocked with anti-Tat antibodies or heparin. Tat down regulated CD127 equally on naive and memory cells and did not require new protein synthesis to have its effect. Tat's down regulation of CD127 was not associated with cell activation as there was no change in overall cell phenotype including expression of CD25 and CD56. Further, expression of CD132, the common gamma-chain which associates with CD127 to form the IL-7 receptor, was also unaffected by Tat. Notably, down regulation of CD127 by Tat resulted in lower induction of the anti-apoptotic protein Bd-2 following stimulation with IL-7. In view of the important role IL-7 plays in CD4 T-cell proliferation, homeostasis and survival, this down regulation of CD127 by Tat may well play a role in HIV-induced immune dysregulation and CD4 T-cell decline. Understanding this effect could lead to new therapeutic approaches to reverse the CD4 T-cell loss evident during HIV infection.
The nature of the metal-insulator transition in silicon germanide quantum wells.

description: A study of the temperature dependence of the resistivity of gated SiGe quantum well structures has revealed a metal-insulator transition as a function of carrier density at zero magnetic field. Although early scaling theories (Abrahams et al., 1979) have argued against the existence of a metal-insulator transition at zero temperature in infinite 2D and 1D systems, more recent theoretical results using a random set of two-dimensional point potentials have shown that such a transition is allowed in two dimensions (Az'bel, 1992). Mounting experimental evidence for such a transition in 2D systems with short range scattering has accumulated in both semiconducting and superconducting structures (Kravchenko et al., 1995, and others). Pseudomorphic, CVD-grown p-type Si/Si$\sb{0.87}$Ge$\sb{0.13}$/Si quantum wells of various widths (65-200 A) have been studied. The samples were gated using a Ti-Au Schottky gate to allow for carrier density variation. Measurement of the transport to quantum lifetime ratio indicates that the transport is dominated by short range scattering. In the temperature range from 400 mK - 4.2 K, the temperature dependence shows a transition from a metallic phase in the high density regime to an insulating phase in the low density regime with a transition boundary close to 2.2 $\times$ 10$\sp $ cm$\sp{-2}$. The scaling properties of the observed metal-insulator transition will be discussed, and compared to previous scaling results from silicon MOSFETs. Below 400 mK, the onset of another transition is accompanied by a sharp drop in resistivity with temperature followed by a monotonic decrease in resistivity below 115 mK. The phase diagram was explored using temperature and density dependences of the current-voltage characteristics.

description: This paper deals with the concept development of a gearbox design for optimum brake energy recovery of a truck trailer with the use of a synchronous reluctance machine. Planetary and or spur gears are selected on the basis of a utility analysis. Based on this, a computer-aided gearbox design tool is developed, which generates an ideal gearbox concept for brake energy recovery on the basis of a motor/generator characteristic and a drive cycle. The optimal gear ratio as well as possible gearbox topologies and gearing are calculated automatically. The possible gearbox topologies are 1- to 3-stage gears consisting of planetary or spur gear stages, and in the case of multi-stage gearboxes, permutations of them. In addition, the configuration of axle drive (one generator with differential) or wheel drive (two generators) can be specified as a starting condition. A joint integration and design process of the gearbox and generator offers many advantages such as compactness, easier handling and faster calculation. An optimization criterion is used to select the appropriate gear unit. As a result, the user receives the optimum gearbox topology, the distribution of the total gear ratio among the stages and the gear geometry, as well as further information on mass, costs, installation space and energy yield. Finally, the gear concept synthesis is validated using analytical equations and commercial gear design software, such as KISSsys and KISSsoft. For this reason, a combination of real driving data determined in VECTO and the analytical calculation of the gearbox generator system is used.
