Printing Embedded Circuits

Automated manufacturing technologies such as freeform fabrication can greatly reduce the cost and complexity of infrastructure required to manufacture unique devices or invent new technologies. Multi-material freeform fabrication processes under development have the potential to automatically build complete functional devices including electronics. Making this technology available to creative individuals will revolutionize art and invention, but requires extensive simplification and cost reduction of what is still a laboratory technology. The combination of a Fab@Home Model 1 personal fabrication system and commercially available materials allows the demonstration of simple and inexpensive freeform fabrication of functional embedded electrical circuits, and useful devices. Using this approach, we have been able to demonstrate an LED flashlight, functional printed circuit boards in 2-dimensions and 3- dimensions that are actually entirely printed, and a child’s toy with embedded circuitry. These results, and the materials and methods involved in producing them will be presented in detail.Mechanical Engineerin

Health and Safety in the Fire Service

The fire service in the United States has problems that span for decades in any aspect you can think of. There has been hardly any improvements on the safety culture for fire departments. There is a need to define these issues and find solutions to the problem. I will be looking at research across the country and some even around the world from the last decade to piece together what is right and what is wrong with the safety culture and the fire service in general and to determine what the best solution and controls to fixing it

Eigenproperties of nonclassically damped dynamic systems

This thesis develops perturbation series solutions for the eigenvalues and eigenvectors of nonclassically damped dynamic systems for the case where the unperturbed system has repeated eigenvalues. The case of repeated eigenvalues is much more complicated than the case of perturbing a system with distinct eigenvalues. Because of this difficulty, only a specific category of dynamic systems with repeated eigenvalues is addressed. Namely, only those systems that when perturbed have series solutions of the form of a power series. This category of systems can be easily identified by an a priori check developed in the application section of this thesis. The issue of existence and convergence of the series solutions is also addressed. To adequately present and defend the above material, the perturbation theory of linear operators is discussed. The more abstract case of defective systems is also discussed in the context of solving such systems with the Puiseux series. The application section of this thesis presents a second order solution for a nonclassically damped system. It demonstrates the application of the convergence condition for the case of repeated eigenvalues and also demonstrates the a priori check that verifies the correctness of a power series solution. Also as a part of this thesis a paper is presented on the series solution of gyroscopic systems with nonclassical damping. This paper develops a series solution for damped gyroscopic system. Also the convergence condition of Peres-Da-Silva et al. is modified to be applicable to gyroscopic systems --Abstract, page iv

Practical experiences in concurrent, collaborative ontology building using Collaborative Protégé

Creation of an ontology according to some common plan is best accomplished collaboratively. This is sometimes contradicted by the distribution of the ontology’s developers. An obvious solution therefore is to build collaboration into ontology development tools. Such support necessarily includes both the technical means to perform editing operations upon an ontology, but also support for the communication that makes collaboration such a vital part of much ontology development. To investigate the distributed, collaborative ontology engineering process and the corresponding capabilities of the Collaborative Protege 3 (CP) tool, members of the OntoGenesis network came together and enriched the Ontology of Biomedical Investigations (OBI) with new content. The communications and interactions of the participants with each other, directly or through the tool, were tracked and analyzed. Our initial analysis of the degree to which this new tool fulfills the practical requirements of collaborative ontology engineering suggests the approach is promising. We present some observations and recommendations for CP based upon this experience

Case Study: Transition to a Vegan Diet in an Elite Male Gaelic Football Player

Vegan diets are increasingly of interest to athletes, but require a well-planned approach in order to mitigate the risk of potential adverse effects on nutrient intakes, and consequently performance. This case study reports the process of an elite male Gaelic football player (age 25 years; height, 1.88 m; body mass, 87.8 kg; lean body mass, 73.26 kg; body fat, 11.3%) transitioning from an omnivorous diet to a vegan diet at the beginning of a competitive season. The report encompasses key considerations in the planning and provision of nutrition support in this context, in addition to iterations needed based on challenges presented by the athlete. Analysis of nutrient intake (Nutritics Dietary Analysis Software), body composition (dual X-ray absorptiometry; Lunar iDXA, GE Healthcare), and running performance during match-play (global positioning system-based tracking; STATSports Apex) each indicated that with adequate knowledge and education, and appropriate planning, commitment and iterative feedback, the athlete was able to meet nutrition targets on a vegan diet without compromising key performance indicators compared to the omnivorous diet of the previous season. We anticipate that this case study will assist practitioners to recognize the key considerations to address when working with athletes transitioning to a vegan diet

MIREOT: the Minimum Information to Reference an External Ontology Term

While the Web Ontology Language (OWL) provides a mechanism to import ontologies, this mechanism is not always suitable. First, given the current state of editing tools and the issues they have working with large ontologies, direct OWL imports have sometimes proven impractical for day-to-day development. Second, ontologies chosen for integration may be under active development and not aligned with the chosen design principles. Importing heterogeneous ontologies in their entirety may lead to inconsistencies or unintended inferences. In this paper we propose a set of guidelines for importing required terms from an external resource into a target ontology. We describe the guidelines, their implementation, present some examples of application, and outline future work and extensions

Modeling Accuracy and Variability of Motor Timing in Treated and Untreated Parkinson’s Disease and Healthy Controls

Parkinson’s disease (PD) is characterized by difficulty with the timing of movements. Data collected using the synchronization–continuation paradigm, an established motor timing paradigm, have produced varying results but with most studies finding impairment. Some of this inconsistency comes from variation in the medication state tested, in the inter-stimulus intervals (ISI) selected, and in changeable focus on either the synchronization (tapping in time with a tone) or continuation (maintaining the rhythm in the absence of the tone) phase. We sought to re-visit the paradigm by testing across four groups of participants: healthy controls, medication naïve de novo PD patients, and treated PD patients both “on” and “off” dopaminergic medication. Four finger tapping intervals (ISI) were used: 250, 500, 1000, and 2000 ms. Categorical predictors (group, ISI, and phase) were used to predict accuracy and variability using a linear mixed model. Accuracy was defined as the relative error of a tap, and variability as the deviation of the participant’s tap from group predicted relative error. Our primary finding is that the treated PD group (PD patients “on” and “off” dopaminergic therapy) showed a significantly different pattern of accuracy compared to the de novo group and the healthy controls at the 250-ms interval. At this interval, the treated PD patients performed “ahead” of the beat whilst the other groups performed “behind” the beat. We speculate that this “hastening” relates to the clinical phenomenon of motor festination. Across all groups, variability was smallest for both phases at the 500-ms interval, suggesting an innate preference for finger tapping within this range. Tapping variability for the two phases became increasingly divergent at the longer intervals, with worse performance in the continuation phase. The data suggest that patients with PD can be best discriminated from healthy controls on measures of motor timing accuracy, rather than variability

Building Effective Community Partnerships

Community Engagement H2O (CE-H2O) is a faith-based student organization that works to serve the community in the Columbus area. This student organization leverages building effective community partnerships with motivating and equipping university teams to advance the health and wellness of four key demographics in the Columbus area. These four communities are the immigrant and refugee population, those suffering in poverty, the orphan population and the widow population. CE-H2O has been effectively equipping university teams to lead community service projects in Columbus for more than five years and has created a model for sustainable, volunteer-based community engagement through a foundation in shared motivation with partner organizations. To create enduring and impactful community partnerships, a shared motivation is needed between the university teams and partnership organizations. For CE-H2O, this shared motivation comes from faith-based motivations for serving the community out of a genuine care for the health and well-being of those in need. CE-H2O is partnered with organizations that serve communities in Columbus through medical clinics, education, hunger relief and human-trafficking abolition. CE-H2O connects student lead university teams with these community partners to promote the health and wellness of these communities. Team development is paramount in maintaining these partnerships, and CE-H2O works diligently to foster growth and leadership in the university teams. Leadership preparation involves monthly CE-H2O meetings in which partnership events are organized; and leaders volunteer to liaison with partner organization to plan and prepare the student teams for the community engagement events. The leaders work to prepare university teams by connecting students to the community partners and lead teams through community engagement events. Student participants have multiple choices in serving with the community partners listed previously. This diversity enables the student to match their passions with the passions of a community partner, which promotes enduring relationships between the students and community partners. Team leaders hold briefings before and after each event to prepare teams for the event and inspire participants to become further involved in community engagement. This presentation is intended for organizations and administrators wanting to learn a sustainable model for creating community partnership with university teams. This presentation is also intended for students seeking community engagement partnerships. The individuals giving this presentation have expertise including more than five years of building effective community partnerships in Columbus, two years of being a student leader for university teams fostering these community relationships, and six months of direct internship experience with a community partner.AUTHOR AFFILIATION: Mike Malone, Pastor, CE-h2o, [email protected] (Corresponding Author); Megan Luthie, Student, CE-h2o; Sarah Stewart, Student, CE-h2o; Daniel Richie, Graduate Teaching Associate, Mechanical and Aerospace Engineering.Community Engagement h2o (CE-h2o) is a faith-based student organization that works to serve the community in the Columbus area.
