Automatically detecting asymmetric running using time and frequency domain features

Human motion analysis technologies have been widely employed to identify injury determining factors and provide objective and quantitative feedback to athletes to help prevent injury. However, most of these technologies are: ex- pensive, restricted to laboratory environments, and can require significant post processing. This reduces their ecological validity, adoption and usefulness. In this paper, we present a novel wearable inertial sensor framework to accurately distinguish between symmetrical and asymmetrical running patterns in an unconstrained environment. The framework can automatically classify symmetry/asymmetry using Short Time Fourier Trans- form (STFT) and other time domain features in conjunction with a customized Random Forest classifier. The accuracy of the designed framework is up to 94% using 3-D accelerometer and 3-D gyroscope data from a sensor node attached on the upper back of a subject. The upper back inertial sensors data were then down-sampled by a factor of 4 to simulate utilizing low-cost inertial sensors whilst also facilitating a decrease of the computational cost to achieve near real-time application. We conclude that the proposed framework can potentially pave the way for employing low-cost sensors, such as those used in smartphones, attached on the upper back to provide injury related and performance feedback in real-time in unconstrained environments

Chris Farrell's Sound Money Guide to Sharing the Wealth

All across the country, Americans get together to share their concerns and passions, especially when it comesto improving their communities. The philanthropic spirit moves people to support the arts, contribute to theiralma maters, construct low-income housing, improve education and tackle all kinds of social ills. America'scharities, nonprofit organizations, and religious congregations are remarkably diverse, ranging from smallgroups of volunteers working out of basement offices to national fraternal organizations with several hundredthousand members to multi-billion dollar enterprises with skyscraper headquarters and global ambitions.Generosity, whether measured in time or money, is on the rise after stagnating for almost a quartercentury following the economic turmoil of the 1970s. Americans gave some $190 billion, or 2.1 percent ofGross Domestic Product, to charities in 1999, according to figures compiled by the American Association ofFund-Raising Counsel. That's up from$124 billion and 1.5 percent of GDP in 1997 (see chart on page 4).Volunteerism is strong, too. Among adults age 18 or over, more than half volunteer their time. In a sense,the nonprofit community is the nation's largest employer with some 109 million volunteers donatingan average of 3.5 hours a week.This guide is designed as an introduction to the major options available for giving money away

First geodetic observations using new VLBI stations ASKAP-29 and WARK12M

We report the results of a successful 7 hour 1.4 GHz VLBI experiment using two new stations, ASKAP-29 located in Western Australia and WARK12M located on the North Island of New Zealand. This was the first geodetic VLBI observing session with the participation of these new stations. We have determined the positions of ASKAP-29 and WARK12M. Random errors on position estimates are 150-200 mm for the vertical component and 40-50 mm for the horizontal component. Systematic errors caused by the unmodeled ionosphere path delay may reach 1.3 m for the vertical component.Comment: 11 pages, 6 flgures, 4 table

Expanding Paramedicine in the Community (EPIC): study protocol for a randomized controlled trial.

BackgroundThe incidence of chronic diseases, including diabetes mellitus (DM), heart failure (HF) and chronic obstructive pulmonary disease (COPD) is on the rise. The existing health care system must evolve to meet the growing needs of patients with these chronic diseases and reduce the strain on both acute care and hospital-based health care resources. Paramedics are an allied health care resource consisting of highly-trained practitioners who are comfortable working independently and in collaboration with other resources in the out-of-hospital setting. Expanding the paramedic's scope of practice to include community-based care may decrease the utilization of acute care and hospital-based health care resources by patients with chronic disease.Methods/designThis will be a pragmatic, randomized controlled trial comparing a community paramedic intervention to standard of care for patients with one of three chronic diseases. The objective of the trial is to determine whether community paramedics conducting regular home visits, including health assessments and evidence-based treatments, in partnership with primary care physicians and other community based resources, will decrease the rate of hospitalization and emergency department use for patients with DM, HF and COPD. The primary outcome measure will be the rate of hospitalization at one year. Secondary outcomes will include measures of health system utilization, overall health status, and cost-effectiveness of the intervention over the same time period. Outcome measures will be assessed using both Poisson regression and negative binomial regression analyses to assess the primary outcome.DiscussionThe results of this study will be used to inform decisions around the implementation of community paramedic programs. If successful in preventing hospitalizations, it has the ability to be scaled up to other regions, both nationally and internationally. The methods described in this paper will serve as a basis for future work related to this study.Trial registrationClinicalTrials.gov: NCT02034045. Date: 9 January 2014

Bilayer Button Graft for Endoscopic Repair of High-Flow Cranial Base Defects

Closure of dural defects in trans-nasal, extended, endoscopic techniques remains a challenge, and published cerebrospinal fluid (CSF) leak rates are higher than rates for trans-cranial approaches. Development of a technique that used a vascularized, nasoseptal flap (NSF) significantly reduced the rate of CSF leak, and several groups have developed ways to buttress the NSF. A closure technique developed at our institution uses a bilayer “button” of fascia lata. The initial series of twenty patients repaired with this method from 2007 to July 1, 2009 were presented, with a CSF leak rate of 10% (Luginbuhl et al 2010)

Slack, Location, Diversification, or R&D Intensity? How the Most (and Least) Innovative Firms Deploy Resources

Firms frequently innovate by recombining knowledge components. Through bringing together diverse scientific or technological concepts, firms can reassemble these extant knowledge components into novel and useful innovations. At the same time, many of the mechanisms firms use to recombine knowledge components carry substantial agency costs. When firms conduct research and development, diversify, hold slack resources, or locate near close competitors, they become vulnerable to misappropriation of investor resources due to opportunistic actions by agents. Using patent citation data from semiconductor firms, we study how firms, which consistently produce high-quality innovations, balance the need for knowledge recombination with the need to protect investors from opportunism. Our results indicate that, consistent with an agency lens, innovative firms operate under a significant debt load. Consistent with the knowledge recombination perspective, however, innovative firms typically engage in multiple activities that lead to innovation via knowledge recombination.https://digitalcommons.odu.edu/gradposters2023_business/1002/thumbnail.jp

Cluster Typologies and Firm Survival: Complementary and Substitutive Effects

Agglomerations, or clusters, are typically defined as the idea that firms can benefit from shared locations through mutual knowledge, labor pools, and suppliers, and have long been a subject of scholarly interest. However, research in geographic economics has identified a broad array of agglomeration externalities beyond such supply-side clusters, which problematizes the use of the term cluster to refer to any geographic grouping of firms. Clusters can be groups of firms from the same country ( country-of-origin clusters), demand side (clustering to lower search costs for customers), Jacobsian clusters (tight groups of diverse firms), internal (groupings of firms from the same parent company), or urban (focused in areas of high population density). Since the nature of inter-firm interactions should differ in each type of agglomeration, our study contributes to the agglomeration literature by identifying complementary and substitutive relationships between agglomeration typologies. Specifically, we extend prior work which has examined the mutual effects of Jacobsian and Marshallian externalities by attempting to answer our research question, i.e., what combination of agglomeration externalities consistently leads to firm survival? Using establishment-level data from the software and clothing industries in the state of Texas, we identify multiple combinations of cluster types (and their absence) which lead to firm survival on a consistent basis. The results find several combinations of causal mechanisms that lead to the equifinal outcome of firm survival. Our configurations exceed levels supported by prior literature with PRI scores over .7 and coverage scores between .05 and .109.https://digitalcommons.odu.edu/gradposters2023_business/1001/thumbnail.jp

The effect of bubble size on the performance of ebullated bed hydroprocessors

A recent cold-flow study has revealed that modifying gas distributor design in three-phased fluidized beds can have a significant effect on overall phase hold-ups and regime transition velocities, even at equivalent phase velocities. It is conjectured that this can be attributed to changes in the bubble-size distribution within the reactor. This study aims to develop a complete kinetic-hydrodynamic model of a resid hydroprocessing ebullated bed reactor with internal recycle in order to study the effects of bubble size distribution on performance metrics of industrial significance. The model consists of combined catalytic and ther-mal reaction models, phase separation efficiency correlations obtained through CFD modelling, catalyst fouling and deactivation models, boiling-point based Vapour-Liquid Equilibria (VLE) relations, and specialized phase hold-up corre-lations developed for resid hydroprocessing applications. A preliminary hydrodynamic model comparing monodisperse bubble sizes between 0.5 mm and 4 mm has been performed. At the lowest bubble size, gas entrainment (and hence gas hold-up) were maximal, while ideal phase separation was achieved at the largest bubble size. Bed gas hold-ups ranged from 10 % to 40 %. Increased gas entrainment was also associated with a decrease in internal liquid recycle ratio required for design ebullation height. The effect of bubble size was most pronounced near a diameter of 1 mm. Ongoing analysis into the effect of bubble recycle on bed gas phase com-position in a reactive system is being performed. The effect of bubble size on liquid residence time and hence conversion will be studied with the objective of determining the optimal bubble size for maximizing key conversion parameters
