    Identification of a two pivot human neck model using linear anterior-posterior perturbations

    Eight healthy young adult males seated in a rigid chair and restrained by a five point harness belt underwent anterior-posterior random appearing multisine perturbations with a frequency range of 0.3-20 Hz. Six different conditions were tested differentiating in maximum acceleration level ([1;2;4;8] m/s²) and in task (mental arithmetic and blindfolded). The head and neck kinematics were captured by a Qualisys motion capture system and Xsens accelerometers. Muscle activity of the trapezius and sternocleidomastoid muscles was collected by a Delsys EMG system. A two pivot neck model was developed representing the head-neck kinematics separating upper and lower neck kinematics. The kinematics were described with an error margin of 2.5 % of the maximum range of motion of the head. The amount of neck deformation relative to the perturbation is expressed in gain and phase, the linearity is expressed in squared coherence. For the head-neck kinematics a significant (P < 0.05) increase in gain was found for decreasing acceleration levels, indicating non-linearity of the human reflexes and/or the passive neck mechanics. At lower frequencies, the mental arithmetic task resulted in a 9 % decrease of neck deformations (P < 0.01). At lower frequencies, blindfolding resulted in a 16 % increase of neck deformations (P < 0.05). The pivot rotations showed for low acceleration levels similar gain and phase characteristics for both the upper and lower pivot up to 3 Hz. Increasing acceleration levels resulted in a major decrease of relative upper neck deformations (P < 0.05) and an increase of relative lower neck deformations (P < 0.01), suggesting different control strategies for both pivots. For frequencies above approximately 5 Hz an increasing phase lag up to 180º for the upper pivot with respect to the lower pivot is found, indicating C-shaped neck bending for low frequencies and S-shaped neck bending for high frequencies. With the exception of the upper pivot response the squared coherence showed globally values above 0.5 between 1-12 Hz.BMechEMechanical, Maritime and Materials Engineerin

    Dystopian and Utopian Homecomings in Shimmer Chinodya’s Harvest of Thorns and Olley Maruma’s Coming Home

    No full text
    The two novels chosen for this paper represent divergent versions of homecoming. Most interestingly, Harvest of Thorns (1989), a victim of scathing attack by cultural nationalists for its suggestively anti-establishmentarian title, and Coming Home (2006), are novels written at different times and feature two different characters whose versions of homecoming do not agree with their particular ‘callings’. The central character in Harvest of Thorns is an ex-guerrilla of the Second Chimurenga (war of liberation that ushered in Zimbabwe’s independence in 1980) who is depicted by the author as having failed to integrate into the ‘home’ he was fighting for. This dystopian depiction of the ‘home’ to which the central character, Benjamin, comes back after the war does not agree with the clichéd rhetoric of nationalist narrative that sees the birth of the new nation in 1980 as the pinnacle of nationalist achievement. On the contrary, Coming Home was written by a euphoric homecoming author and intellectual; his narrator is also ‘coming home’ (and celebrates all the associated nationalist utopias of that period) at a period leading towards 1980. Why would Coming Home be written in 2007 at a time when the majority of Zimbabweans were exiting home? These divergent views beg for closer analysis of the texts especially focusing on how Harvest of Thorns shatters nationalist narration while Coming Home desperately reconstructs it

    In Search of the "Telling Detail": Ian McEwan, Briony Tallis, and the Demands of Authorship

    No full text
    Much scholarly interest surrounding Ian McEwan's Atonement has focused on the abrupt shift that occurs in the novel's final section, "London, 1999." This essay argues that this section makes it clear that the main story of the novel is not Briony, Robbie, and Cecilia's entanglement due to Lola's teenaged rape but Briony's development as a writer, her kunstlerroman. As such, it is crucial to the novel, not simply a metafictional ploy, because it illuminates the lengths she has gone to in writing her final book and fulfilling her youthful promise. McEwan's response to a real-life plagiarism accusation reinforces his depiction of Briony as an author who searches for "the telling detail," as opposed to one who sticks to verifiable, historical accuracy

    The use of Charts, Pivot Tables, and Array Formulas in two Popular Spreadsheet Corpora

    No full text
    The use of spreadsheets in industry is widespread. Companies base decisions on information coming from spreadsheets. Unfortunately, spreadsheets are error-prone and this increases the risk that companies base their decisions on inaccurate information, which can lead to incorrect decisions and loss of money. In general, spreadsheet research is aimed to reduce the error-proneness of spreadsheets. Most research is concentrated on the use of formulas. However, there are other constructions in spreadsheets, like charts, pivot tables, and array formulas, that are also used to present decision support information to the user. There is almost no research about how these constructions are used. To improve spreadsheet quality it is important to understand how spreadsheets are used and to obtain a complete understanding, the use of charts, pivot tables, and array formulas should be included in research. In this paper, we analyze two popular spreadsheet corpora: Enron and EUSES on the use of the aforementioned constructions.Software Engineerin

    An experimental study of the effects of pitch-pivot-point location on the propulsion performance of a pitching airfoil

    An experimental investigation was conducted to characterize the evolution of the unsteady vortex structures in the wake of a pitching airfoil with the pitch-pivot-point moving from 0.16C to 0.52C (C is the chord length of the airfoil). The experimental study was conducted in a low-speed wind tunnel with a symmetric NACA0012 airfoil model in pitching motion under different pitching kinematics (i.e., reduced frequency k=3.8-13.2). A high-resolution particle image velocimetry (PIV) system was used to conduct detailed flow field measurements to quantify the characteristics of the wake flow and the resultant propulsion performance of the pitching airfoil. Besides conducting "free-run" Ply measurements to determine the ensemble-averaged velocity distributions in the wake flow, "phase-locked" PIV measurements were also performed to elucidate further details about the behavior of the unsteady vortex structures. Both the vorticity-moment theorem and the integral momentum theorem were used to evaluate the effects of the pitch-pivot point location on the propulsion performance of the pitching airfoil. It was found that the pitch-pivot-point would affect the evolution of the unsteady wake vortices add resultant propulsion performance of the pitching airfoil greatly. Moving the pitch-pivot-point of the pitching airfoil can be considered as adding a plunging motion to the original pitching motion. With the pitch-pivot-point moving forward (or backward), the added plunging motion would make the airfoil trailing edge moving in the same (or opposite) direction as of the original pitching motion, which resulted in the generated wake vortices and resultant thrust enhanced (or weakened) by the added plunging motion.

    Teaching in the Age of AI Tools: Considerations for Xavier\u27s Writing Program

    No full text
    The release of OpenAI’s ChatGPT and other artificial intelligence technologies have raised multiple concerns for educators, including uncertainty about the platform’s abilities and questions on how best to respond to students potentially using AI to complete assignments. In order to address these concerns, research into the current capabilities and limitations of AI programs like ChatGPT was conducted. These metrics were determined based off statements released by OpenAI and other experts in the field of artificial intelligence, along with manual testing of the technology. Building off of these parameters allowed the research to then pivot to potential AI policies that would be the most beneficial to both students and faculty in Xavier University’s Writing Program. The policy was shaped by articles from other educators, advice from organizations such as the Modern Language Association (MLA) and American Psychological Association (APA), statements from educational committees, and resource pages from other Jesuit universities to determine what approaches are encouraged by experts and to see how other institutions of higher education are responding to the hurdles that AI poses
