Year: 1995
Subjects: subject: Information Science.

description: This study discusses the generation of the minimum length checking sequences for FSM-based protocol conformance testing. The discussion focuses on finding the minimal length of resulting checking sequences for an FSM under different conditions. Without interleaving state identification and transition verification sequences, four methods (D-method, W-method, Wp-method and UIOv-method) of generating minimum length test sequences for FSM$\rm \sb{s}$ with reliable reset feature are reviewed and provided to construct checking sequences. These four methods are then improved to generate minimum length checking sequences for FSM$\rm \sb{s}$ without reliable reset feature and provided to construct checking sequences. Moreover, the effects of interleaving the state identification and transition verification sequences on the length of the checking sequences are studied. An algorithm for interleaving the state identification and transition verification sequences generated by the above four methods with reliable reset feature is proposed. It is observed that the reduction in the length of checking sequences due to interleaving is significant. Finally, the two general models for constructing minimal length checking sequences using distinguishing sequences with interleaved state identification and transition verification sequences are proposed. The proof for the first model to find a minimum length checking sequence in polynomial time is provided. The sequences generated by using both models are proved to be checking sequences. Examples are provided as applications of all the proposed methods and models.
Aerodynamics of rectangular slot-burners and combustion in tangentially-fired furnace

description: The power generation industry in the state of Victoria, Australia stands to gain significantly from process improvements and optimization which can potentially lead to cleaner production of cost effective electricity. The efficient operation of lignite based tangentially-fired combustion systems depends on critical issues such as ignition and combustion of the fuel, which are largely controlled by burner aerodynamics. The geometry of the burner and the ratio of velocities between the primary and secondary jets play an important role in achieving stable combustion, high burnout of fuel, low production of pollutants and control of fouling. Slot-burners are a vertically aligned stack of rectangular nozzles delivering primary fuel and secondary air jets, and are commonly used in tangentially-fired boilers. To obtain a better understanding of the overall combustion process, it is important to understand the aerodynamics of jet development from these burners. The starting point of this research was a CFD investigation of aerodynamics in the near-burner region of isolated rectangular slot-burners, using isothermal conditions, for various secondary to primary jet velocity ratios (φ). Cross-flow was then added to replicate a near-burner flow field similar to that found in a tangentially-fired furnace and the effect of changing φ in the near-burner region of the developing jets was again investigated. Experiments were carried out on an isothermal physical-burner model to obtain mean velocity and turbulent statistics for different nozzle geometries and a range of φ. A computational fluid dynamics investigation of these same jets was also performed to gain further insights into the complexities of flow field with experimental results used to validate CFD predictions. The primary jet substantially deviated from the geometric axis of the burner towards the furnace wall and became very unstable for higher φ. The causes of unfavourable aerodynamics were discussed and suggestions were made on possible remedies for such behaviour. Conventional lignite combustion in a full-scale tangentially-fired furnace was modelled. The model was used to assess the possibility of utilizing a new type of mechanically thermally dewatered (MTE) coal in existing furnaces.

description: This study compared the cardiovascular responses to the PWC 140, cold pressor test (CPT), and isometric hand grip (IHG), to evaluate the consistency in the blood pressure response among these physical stressors. Eighteen resting normotensive males were classified as either normotensive at exercise or exercise hypertensive on the basis of their blood pressure response to the first stage of the Canadian Aerobic Fitness Test (CAFT) for their age group. Subjects were administered a 6-min PWC 140 bicycle ergometer test, a 120 sec CPT (forearm and hand immersion), and a 120 sec IHG at 30% MVC. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), stroke volume (SV), cardiac output (CO), and ejection fraction (EF) were recorded every 5 seconds during a one min resting period, during exercise, and for 3 min post exercise using a Finapress 2000 BP monitor and BoMed bioimpedance cardiac monitor. The results of this study indicate that: (1) there were no significant differences between the two groups for the cardiovascular responses to the PWC 140, IHG, and CPT with the exception of a greater CO and SV in normotensives on the PWC 140, and a higher HR in exercise hypertensives on the CPT; (2) the exercise hypertensives had a greater rate of increase in SBP and DBP than the normotensives over the first 90 seconds of the CPT; (3) there was no consistent pattern in the individual responses to the CAFT, CPT, and IHG with respect to $\Delta$SBP. It was concluded that within the context of this study, the blood pressure responses to dynamic exercise, isometric exercise, and cold stress were not consistent among the subjects and tests.

description: A synthetic wastewater containing 20 mg/L 2,4-dichlorophenol (2,4-DCP) and medium-strength carbonaceous co-substrate (7 g COD/L) was used to investigate the feasibility of treating chlorophenols in laboratory-scale sequencing batch upflow anaerobic sludge blanket reactors, designated as SBAR. The specific organic loading rate (SOLR) and specific 2,4-DCP loading rate (SDCPLR) tested were 0.35, 0.53, 0.70 g COD/g VSS/d and 1.0, 1.5 and 20 mg 2,4-DCP/g VSS/d, respectively. For each SOLR and SDCPLR operating condition, three different fill/react ratios, 0.33, 0.66 and 1.00 were examined in order to assess the performance of SBAR operating strategies. One continuous upflow anaerobic sludge blanket (UASB) reactor used as the control was operated at three SOLR and SDCPLR corresponding to those applied to SBARs. Experimental results show that laboratory-scale SBARs were able to treat 2,4-DCP contaminated wastewater in addition to medium-strength carbonaceous co-substrate. The over all removal efficiencies of SBARs were almost 100% for 2,4-DCP and ranged from 72.5% to 94.2% for carbonaceous co-substrate. Under studied conditions, the performance of the continuous flow reactor was quite similar to that of sequencing batch reactors. Removal efficiencies for the continuous flow reactor were almost 100% for 2,4-DCP and ranged from 84.2% to 93.3% for COD. The major biodegradation product of 2,4-DCP in both sequencing batch and continuous UASB reactors was 4-monochlorophenol. This experimental work also confirmed earlier observations that SOLR significantly influenced the overall COD removal efficiency of the SBAR, and SOLR based on fill time (SOLR)$\sb{\rm f}$ is an important design parameter for SBAR systems. Experimental data from this study were also compared with the simulated results obtained using a previously developed dynamic SBAR model. It was verified that this model can predict the SBAR performance reasonably well.

description: Childhood maltreatment (CM) is associated with an increased risk for the development of psychiatric and somatic disorders in later life. A potential link could be oxidative stress, which is defined as the imbalance between the amount of reactive oxygen species (ROS) and the neutralizing capacity of anti-oxidative defense systems. However, the findings linking CM with oxidative stress have been inconsistent so far. In this study, we aimed to further explore this association by investigating biological markers of DNA and lipid damage due to oxidation in a comprehensive approach over two study cohorts of postpartum women (study cohort I and study cohort II). The severity of CM experiences (maltreatment load) was assessed in both studies using the Childhood Trauma Questionnaire. In study cohort I (N = 30), we investigated whether CM was associated with higher levels of structural DNA damage in peripheral blood mononuclear cells (PBMC) by two methods that are highly sensitive for detecting nuclear DNA strand breaks (comet assay and γH2AX staining). In study cohort II (N = 117), we then assessed in a larger cohort, that was specifically controlled for potential confounders for oxidative stress measurements, two established serum and plasma biomarkers of oxidative stress, one representing oxidative DNA and RNA damage (8-hydroxy-2′-deoxyguanosine and 8-hydroxyguanosine; 8-OH(d)G) and the other representing lipid peroxidation (8-isoprostane). In study cohort I, the analyses revealed no significant main effects of maltreatment load on cellular measures of nuclear DNA damage. The analyses of peripheral oxidative stress biomarkers in study cohort II revealed a significant main effect of maltreatment load on free 8-isoprostane plasma levels, but not on total 8-isprostane plasma levels and 8-OH(d)G serum levels. Taken together, by combining different methods and two study cohorts, we found no indications for higher oxidative DNA damages with higher maltreatment load in postpartum women. Further research is needed to investigate whether this increase in free 8-isoprostane is a marker for oxidative stress or whether it is instead functionally involved in ROS-related signaling pathways that potentially regulate inflammatory processes following a history of CM.
The role of providence in the "New Science" of Giambattista Vico.

description: The question of how to interpret the role of providence in the New Science of Giambattista Vico (1668-1744) is one of the most vexing problems of interpretation surrounding Vico's magnum opus. In this essay I come at the problem by attempting to understand Vico's theory of knowledge and how it comes to bear upon his interpretation of history. In chapter one I offer a phenomenology of the historical world according to Vico. I consider the problem of historical knowledge as such and attempt to show that Vico makes an original contribution by his insistence that we need to critically appropriate the historical texts from the past. In chapter two I explore some of the main features of Vico's epistemology. I then attempt to get more deeply into Vico's view of history by looking at him through important interpretations. In chapter three I discuss the interpretation of Leon Pompa. In chapter four I discuss the interpretation of Vichian epistemology found in the work of Donald P. Verene. In a fifth and final chapter I attempt to then make some determination of how providence functions in the NS. I seek to interpret Vico's providence doctrine as requiring a transcendental referent or God, based on the verum-factum principle as the central epistemic model. (Abstract shortened by UMI.)

description: A fourfold subdivision and a correlation of the calcareous parts of the Tully Formation in New York and Pennsylvania are based on the ratios of the abundance of the conodonts Polygnathus linguiformis, P. varca, P. iuvenis and Icriodus. The statistical distribution of the four taxa is independent of the local lithology, but follows stratigraphical units. The studied conodont faunal succession of the Tully Formation includes a conodont zone not yet described from Europe. This new zone is thought to be younger than the base of the Assise de Fromelennes (Upper Devonian, France) and is furthermore correlated with the lowest part of the to 1alpha zone (Upper Devonian, Germany). The conodonts of the Tully Formation are considered to be similar to those of the lower Geneseo Shale, the Alto Formation (Illinois), and the Cedar Valley Limestone (Minnesota).

description: Sediments, located near Cornwall have been historically contaminated with Hg and other metals by local industries. Cornwall was designated an area of concern by the International Joint Commission (IJC) in 1985. The concentrations of mercury in these sediments exceeded the sediment quality guideline (SQG), of 170 ng g-1 set by Environment Canada for the protection of aquatic biota. To identify the role of these contaminated sediments on mercury dynamics in the river, I measured concentrations of total mercury (THg) and methyl mercury (MeHg) in both the porewater and solid phase of sediment cores and in the overlying water to determine whether sediments are a net source or sink for Hg. A comparison of porewater profiles in June, July and August of 2007 revealed little seasonal variation in MeHg concentrations. I also compared THg and MeHg vertical profiles in sediments with complimentary redox-dependent variables, including sulfate, sulfide, and Fe2+ distributions which showed that zones of active sulfate reduction and Fe reduction have little effect on the distribution of dissolved MeHg in the sediments. THg in sediment cores was related to the sediment accumulation rates by 210Pb radiochronology which showed the history of industrial Hg emissions to the river. MeHg contributed 4% to 100% of the THg in the porewater samples, whereas in the solid phase it contributed less than 1% of the THg. There was little to no diffusion of THg and MeHg from sediments to the overlying water. I have concluded that sediments are a major sink for THg and MeHg to the St. Lawrence River near Cornwall.

description: Nitrogen (N) is critical to the quantity and quality of agricultural yields. Excess N fertilization is costly, both economically and environmentally (nitrate leaching, eutrophication, greenhouse gas release, soil degradation). This research identifies zones that could substitute the field-long N-rich strips by using spatial analysis of the nitrogen sufficiency index (NSI) and the relation with Apparent Electrical Conductivity (ECa), Elevation, Slope and Soil. NSI calculated from ECa grouped into three classes was capable of minimizing the effects on NDVI. Correlation coefficients (R) between three-class NSI and NSI calculated from the nearest ECA values were very high for all the fields with values between 0.82< R <0.94, with the highest coefficients associated with fields in 2005 and 2007. Meanwhile, three-class NSI coefficients were consistently significant in relation to the NSI reference, with an average of R=0.79 for all the fields. The highest coefficient was detected for 2007, with R=0.89, whereas the lowest values were associated with 2006 (R=0.67). In the case of elevation grouped into four classes, the correlation results were not statistically significant, with overall average values of R<0.70. The maps elaborated from the NSI for ECa grouped into three classes show a high level of accuracy compared to the NSI reference map. The new N-rich zones not only can contribute to mitigating the environmental impact of agricultural practices (reducing 77% of N inputs) but also be an accurate source of data for the analysis of NSI and within-field N variability.

description: Stability in genome organization has been widely studied by comparing physical and genetic maps of different genomes and, by comparing complete sequences from different genomes. Many of these comparative studies between related species have shown some measure of conservation in gene organization. In order to determine if rearrangements in gene organization occur gradually over time, a set of related species needed to be compared in detail. My research consisted of a comparative sequence analysis of a selected region of the genome of various crenarchaeotal species belonging to the order Sulfolobales. More specifically, the gene organization of an equivalent 40-50 kbp region that surrounds the 16S rRNA gene of seven related strains or species was compared. The hypothesis of this research was that rearrangements in gene organization mirror phylogenetic history. Results from the analysis showed many blocks of conserved gene organization. A qualitative tree based on these similarities in gene order was constructed for comparison with the actual distance tree based upon the 16S rRNA sequences. My hypothesis was refuted on the basis that changes in gene organization did not mirror the phylogeny. Instead, my comparative analysis supported a punctuated model of genomic evolution. The use of gene order as a parameter to build phylogenies is discussed.

description: The model of Clem and Hao and others is extended to account for the enhancement of the Meissner effect observed in single crystals of hysteretic type II superconductors upon thermal cycling below Tc in static applied magnetic fields. Predictions are made about the features of the final closed thermal hysteretis loop achievable by extensive cycling and their dependence on the temperature limits T1 and T2 < Tc chosen for the cycles. A large variety of observations, by several workers, of a narrow peak of enhanced Meissner effect near Tc in polycrystalline type II superconductors upon slow warming in static applied fields after fast field cooling, are qualitatively and quantitatively accounted for by a model where we introduced the scheme developed above for single crystals into a weak-linked intergranular network (matrix). This "two tier" framework is then extended to describe the enhancement of the Meissner effect observed by Hyun by thermal cycling of weak-linked Nb3Sn below Tc in a static field. A simple framework is presented which quantitatively develops the proposal of Evetts and Glowacki that the superposition of the applied field H a and the return field, Hr of the magnetized grains, is the cause of the hysteretic behaviour of Ic in weak-linked high T c superconductors and the occurrence of a peak in Ic versus Ha descending and reascending, after an excursion to various values, denoted Hcycle, or after field cooling in different H cool. Observations by several workers on the dependence, of the position of four categories of peaks of Ic, on Hcycle and Hcool are reproduced by this model and yield estimates of the "compression" factor C in the linear dipole approximation, H r = C Mg. We also show that, ratios of the measured plateau values for the position of these peaks, lead to an estimate for C which is independent of H·g, the penetration field into the grains, and of the model chosen to calculate the dependence of the magnetization of the grains, Mg, on Ha. Instead of the artificial pseudo-Josephson - junction expression generally used by other workers in the analysis of Ic hysteresis phenomena, we develop a family of formulae based on the critical state concept applied to idealized planar geometry. Exploiting an especially simple case from this family of formulae we reproduce a panoply of experimental curves of Ic versus Ha displayed in the literature and exhibiting a variety, of features. Analysis of the extensive data of List et al reveals that our approach leads to results in accord with observations whereas the Josephson junction format does not. (Abstract shortened by UMI.)

description: This thesis provides a comparative analysis of sentencing patterns in two time periods separated by seventeen years. Research of this type has not been attempted previously, due to the limited availability of historical sentencing data. Using statistics obtained from the Royal Canadian Mounted Police's Fingerprint System from 1983--1984 and the Canadian Centre for Justice Statistics' Adult Criminal Court Survey for 1999--2000, this study examines whether recommendations made by various federal inquiries into sentencing have affected judicial decision-making at the trial court level. At the core of this discussion is an examination of those initiatives aimed at reducing the use of imprisonment as a sanction. Comparisons reveal that sentencing patterns in 1983--1984 differed significantly from those present in 1999--2000. In some cases, it appears as though the changes were in accordance with recommendations of the federal inquiries whereas in others, the patterns that were discovered seemed to indicate that judges ignored or even defied the directives given. With regard to the promotion of community sanctions, there was an overwhelming increase in the use of probation. In contrast, the findings with respect to the use of imprisonment were more ambiguous; while the overall decrease in the rate of incarceration had been a stated objective, the manner in which this reduction was achieved appears to contradict the recommendations of the inquiries. Essentially, this study shows that, despite the wealth of time and research devoted to the reform of the sentencing process in this country, the impact of these efforts on judicial practices has been minimal.

Mixing and temporal variation in the groundwater flow system at the Con Mine, Yellowknife, Northwest Territories, Canada: An analogue for a radioactive waste repository.
Creators: name: Douglas, Malcolm Charles.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Geology.

description: The spatial and temporal variations in geochemistry and isotopes of groundwaters at the Con Mine in Yellowknife, N.W.T., Canada, have provided insights to the impact of mining on the local hydrogeological environment. The study explores the use of mine hydrology in an analogous setting to assess the impact of a radioactive waste repository on groundwater flow, and surface to depth pathways in the Canadian Shield. The 50 years of mining activity at the Con mine fit the time frame envisaged for the construction and operation of a repository. Inflow at eighteen boreholes and three faults was periodically monitored from 1994 to 1996. Groundwater discharge in the mine is a mixture of fresh water to brine, with maximum TDS of 290 g/L, at depths of 701 m to 1,615 m below surface. Three end-members are identified: (1) Shield brine typical of deep crystalline environments, (2) early Holocene precipitation and glacial melt water, and (3) recently recharged meteoric water. A body of glacial water emplaced at the time of deglaciation, has remained stable under the low hydraulic gradients in deep groundwater flow in the low-relief setting of the shield terrain, until disturbed by the steep surface to depth gradients imposed by mining activities.

Year: 2024

description: We take a closer look at the probable demand for bandwidth that is presumed to motivate the deployment of new broadband access technologies. We construct plausible estimates of what a 'typical home' might need given two different service provision scenarios – managed bandwidth and best-effort statistical multiplexing. We estimate a household of five people requires between 58 and 113Mbit/sec if bandwidth is managed on a per-application basis. If statistical multiplexing is used, the same family's bandwidth requirements jump to between low hundreds of Mbit/sec to almost a Gbit/sec.

Alcaeus and the sea.

Subjects: subject: Literature, Classical.

description: The first usage of the ship of state allegory is commonly attributed to the seventh century B.C. poet Alcaeus. While it is true that in his corpus of poetry we see the first explicit usage of such imagery, the possibility that it was employed by earlier poets is strong. This thesis is a detailed examination of five fragmentary poems and commentaries, its purpose being to determine Alcaeus' sources of inspiration for the ship of state allegory and to assess the degree of his originality and his effectiveness in using it. After surveying contemporary literary sources for definitions of allegory, it can be established that the ancients viewed it as a lengthened metaphor or metaphorical sequence, employed to veil the meaning of a text. The expressions chosen by Alcaeus to describe the travails of the ship are then examined to determine whether he has directly imitated or adapted phrases from his literary predecessors and if this is so, to assess the effectiveness of the imitation in terms of an allegorical representation of political strife. Although it is evident that Alcaeus adopts images and expressions previously employed, this study reveals that he is creative in assigning new meaning to certain expressions and that he imitates passages for their power to evoke a particular image. The association with the model is subsequently elaborated upon through the employment of unusual choices in vocabulary, either to sustain dual imagery or predispose his audience to think in figurative terms. Thus the evocation of images from earlier authors coupled with key internal allegorical indicators allows Alcaeus to convey successfully to his closed audience their political plight in the guise of danger at sea.

The relationship between statistical power and predictor distribution in multilevel logistic regression: a simulation-based approach

description: Background: Despite its popularity, issues concerning the estimation of power in multilevel logistic regression models are prevalent because of the complexity involved in its calculation (i.e., computer-simulation-based approaches). These issues are further compounded by the fact that the distribution of the predictors can play a role in the power to estimate these effects. To address both matters, we present a sample of cases documenting the influence that predictor distribution have on statistical power as well as a user-friendly, web-based application to conduct power analysis for multilevel logistic regression. Method: Computer simulations are implemented to estimate statistical power in multilevel logistic regression with varying numbers of clusters, varying cluster sample sizes, and non-normal and non-symmetrical distributions of the Level 1/2 predictors. Power curves were simulated to see in what ways non-normal/unbalanced distributions of a binary predictor and a continuous predictor affect the detection of population effect sizes for main effects, a cross-level interaction and the variance of the random effects. Results: Skewed continuous predictors and unbalanced binary ones require larger sample sizes at both levels than balanced binary predictors and normally-distributed continuous ones. In the most extreme case of imbalance (10% incidence) and skewness of a chi-square distribution with 1 degree of freedom, even 110 Level 2 units and 100 Level 1 units were not sufficient for all predictors to reach power of 80%, mostly hovering at around 50% with the exception of the skewed, continuous Level 2 predictor. Conclusions: Given the complex interactive influence among sample sizes, effect sizes and predictor distribution characteristics, it seems unwarranted to make generic rule-of-thumb sample size recommendations for multilevel logistic regression, aside from the fact that larger sample sizes are required when the distributions of the predictors are not symmetric or balanced. The more skewed or imbalanced the predictor is, the larger the sample size requirements. To assist researchers in planning research studies, a user-friendly web application that conducts power analysis via computer simulations in the R programming language is provided. With this web application, users can conduct simulations, tailored to their study design, to estimate statistical power for multilevel logistic regression models.

Subjects: subject: Engineering, System Science.

description: One important application of image processing and computer vision is traffic monitoring and control. In this thesis, a system for detection of moving vehicles approaching an intersection from a sequence of color images acquired by a stationary camera in the context of traffic light control systems is presented. As the system is dedicated to outdoor applications, efficient and robust vehicle detection under various weather and illumination conditions is examined. To deal with these ever changing conditions, vehicle detection relies on motion segmentation and on an original algorithm using color mapping to achieve feature space segmentation. Experimental results on real outdoor sequences of images demonstrate the system's robustness under various environmental conditions.
