Fast spatial interference canceller based on the Dobson algorithm
No full textThe Dobson algorithm, an algorithm for adaptive antenna arrays, was first described in 1988. In this work only narrow-band signals were assumed and a brief look was taken at the theoretical aspects of the algorithm. In the simulations non realistic signal to noise ratios, SNR, were assumed. This report contains a presentation of a theoretical analysis of the Dobson algorithm. Furthermore, the theory was extended to wide band systems and a criterion is presented which detects jammers in noisy signals. This criterion is based upon predicting the expected noise power at the output of the array. Simulation results are given for realistic SNR ( 10-20 dB). Simulation results support the theory. The power of the jammers can easily be suppressed, to a level of the same order as the noise power. The problems that may arise with the implementation of the algorithm are discussed. A new application for a semi-mobil system is presented. At this moment no results of experiments with systems using the Dobson algorithm are available. Therefore the next step in the research should be the implementation and testing of a system based on the Dobson algorithm.Electrical Engineering, Mathematics and Computer ScienceTelecommunicatie- en Verkeersbegeleidingssysteme
We Are Already Ghosts: Reflections on Composition
No full textIn this piece, author and critic Kit Dobson discusses and analyzes the composition of his debut novel, We Are Already Ghosts (University of Calgary Press, 2024). He analyzes the novel along at least three axes: first, as a novel that can be classified as a character-driven “summer read”; second, as a work of experimental fiction; and, third, as a text that analyzes and interrogates the spaces that make up the Canadian province of Alberta. Dobson notes influences on the novel from Virginia Woolf’s To the Lighthouse; to the poetics of bpNichol; to the tension between settler and Indigenous understandings of land, territory, haunting, and presence. Throughout, Dobson notes that the time in which the novel is set, between 1996 and 2011, marks a period of transition for the Briscoe-MacDougall family members who populate the book, and for the world and society that these characters represent
Fitness implications of seasonal climate variation in Columbian ground squirrels
No full textThe influence of climate change on the fitness of wild populations is often studied in the context of the spring onset of the reproductive season. This focus is relevant for climate influences on reproductive success, but neglects other fitness‐relevant periods (e.g., autumn preparation for overwintering). We examined variation in climate variables (temperature, rainfall, snowfall, and snowpack) across the full annual cycle of Columbian ground squirrels (Urocitellus columbianus) for 21 years. We investigated seasonal climate variables that were associated with fitness variables, climate variables that exhibited directional changes across the study period, and finally observed declines in fitness (−0.03 units/year; total decline = 37%) that were associated with directional changes in climate variables. Annual fitness of adult female ground squirrels was positively associated with spring temperature (r = 0.69) and early summer rainfall (r = 0.56) and negatively associated with spring snow conditions (r = −0.44 to −0.66). Across the 21 years, spring snowmelt has become significantly delayed (r = 0.48) and summer rainfall became significantly reduced (r = −0.53). Using a standardized partial regression model, we found that directional changes in the timing of spring snowmelt and early summer rainfall (i.e., progressively drier summers) had moderate influences on annual fitness, with the latter statistically significant (ρ = −0.314 and 0.437, respectively). The summer period corresponds to prehibernation fattening of young and adult ground squirrels. Had we focused on a single point in time (viz. the onset of the breeding season), we would have underestimated the influences of climate change on our population. Rather, we obtained a comprehensive understanding of the influences of climate change on individual fitness by investigating the full lifecycle.Ye
A Balancing that is Beyond the Scope of the Common Law: A Discussion of the Issues Raised by Dobson v. (Litigation Guardian of) Dobson
No full textThis article examines whether a child should have the legal right to sue its mother for harms alleged to have been caused by her negligence during pregnancy. The author begins with an overview of relevant jurisprudence on the legal status of the fetus and on the right of children to sue a third party for pre- birth injury. Jurisprudence on the right of a child to sue its mother for pre-birth injury is also outlined.
The author then critically examines the decision of the Supreme Court of Canada in Dobson (Litigation Guardian of) v Dobson where the court held, on public policy grounds, that a child did not have the legal right to sue its mother. In the author\u27s view, this decision is correct given the limitations of the common law, although it does not appropriately balance the interests of pregnant women with those of injured children who require compensation for their special needs.
She advocates legislative reform because the legislature is better equipped to deal with polycentric issues and would be able to provide a particularized, results-oriented response. Specifically, the author recommends legislation, patterned on the United Kingdom\u27s Congenital Disabilities Act, 1976, which would allow a child to sue its mother only where the alleged negligence relates to the operation of a motor vehicle. The author argues that such legislation is the best way to provide children like Ryan Dobson with the care they need, while avoiding the harmful consequences of imposing a general tort liability on pregnant women vis-a-vis their fetuses

The author skilfully explains complex and daunting concepts in an unpretentious manner that simultaneously demystifies the research process and illuminates the complexity and messiness of actual research, writes Christina Dobson
Review of \u3ci\u3eSeldom Seen: A Journey into the Great Plains\u3c/i\u3e by Patrick Dobson
No full textThe Great Plains often are dismissed as ho-hum fly-over country lacking in significance or appeal. But in the skillfully written narrative of Seldom Seen, Patrick Dobson describes how he finds the Plains a source of emotional sustenance and, ultimately, rejuvenation. Seldom Seen is the story of the author\u27s trek, largely by foot, from Kansas City, Missouri, to Helena, Montana. Along the way Dobson-- a 32-year old blue-collar worker seeking relief from a variety of intense personal frustrations-meets a long string of open-hearted if often dirt-poor souls and comes to find hope in what he\u27d largely considered a mean and unforgiving world.
Seldom Seen stands as a heartfelt if idiosyncratic expression of affection for the Plains region. But the book is above all an exploration of self. At times it risks losing the reader by ladling out so many heavy dollops of Dobson\u27s angst. Still, the author displays a keen literary sense, and the vignettes he presents of a wide variety of Plains locales are often vivid. Dobson ably describes significant cultural tangents such as a young Kansan\u27s intense love of farming-emblematic of small farmers\u27 devotion to agriculture even in the face of enormous challenges-as well as Native American bemusement at whites\u27 mistaken stereotypes and fears
An assessment of the stray light in 25 years of Dobson total ozone data at Athens, Greece
No full textIn this study, we investigated the susceptibility of the Dobson spectrophotometer No. 118 to stray light interference. In this regard, a series of total ozone content measurements were carried out in Athens, Greece for air-mass values (μ) extending up to μ = 5. The monochromatic-heterochromatic stray light derived by Basher's model was used in order to evaluate the specific instrumental parameters which determine if this instrument suffers from this problem or not. The results obtained indicate that the measurements made by the Dobson instrument of the Athens station for air mass values up to 2.5, underestimates the total ozone content by 3.5 DU in average, or about 1 % of the station's mean total ozone content (TOC). The comparison of the values of the same parameters measured 15 years ago with the present ones indicates the good maintenance of the Dobson spectrophotometer No. 118. This fact is of crucial importance because the variability of the daily total ozone observations collected by the Athens Dobson Station since 1989 has proved to be representative to the variability of the mean total ozone observed over the whole mid-latitude zone of the Northern Hemisphere. This stresses the point that the Athens total ozone station, being the unique Dobson station in south-eastern Europe, may be assumed as a ground truth station for the reliable conversion of the satellite radiance observations to total ozone measurements. © Author(s) 2015
