Machine Learning Based AFP Inspection: A Tool for Characterization and Integration

Automated Fiber Placement (AFP) has become a standard manufacturing technique in the creation of large scale composite structures due to its high production rates. However, the associated rapid layup that accompanies AFP manufacturing has a tendency to induce defects. We forward an inspection system that utilizes machine learning (ML) algorithms to locate and characterize defects from profilometry scans coupled with a data storage system and a user interface (UI) that allows for informed manufacturing. A Keyence LJ-7080 blue light profilometer is used for fast 2D height profiling. After scans are collected, they are process by ML algorithms, displayed to an operator through the UI, and stored in a database. The overall goal of the inspection system is to add an additional tool for AFP manufacturing. Traditional AFP inspection is done manually adding to manufacturing time and being subject to inspector errors or fatigue. For large parts, the inspection process can be cumbersome. The proposed inspection system has the capability of accelerating this process while still keeping a human inspector integrated and in control. This allows for the rapid capability of the automated inspection software and the robustness of a human checking for defects that the system either missed or misclassified

Lenhoff, & Bentley A. Krause, PhD, AT Ohio University, College of Health Sciences & Professions, Division of Athletic Training. ____________________________________________________________________ Context: Athletic trainers (ATs), more than any other healthcare professional, has expertise in areas of on-field assessment and management of sport related concussion and spinal cord injury. A search of the key words “brain” (n=\u3e100) or “spinal cord/spine” (n=~50) were identified in National Athletic Trainers’ Association Position Statements on Concussion and Spinal Cord Injury. However, a significant gap exists in the basic science knowledge of neuroscience and neuroanatomy. Objective: The goal of this study is to identify the basic science coursework in professional and post-professional athletic training curricula. Design and Setting: This is a descriptive, curricula analysis of CAATE Professional and Post-Professional Athletic Training Programs using web-based search and review. Participants: Curricula for accredited Professional (n=336) and Post-Professional (n=15) Athletic Training Programs were reviewed and analyzed to characteristics basic science content. Interventions: This web-based program review of CAATE standard course content and elective options occurred. Main Outcome Measures: Course titles, numbers and descriptions were accessed at CAATE.net and offerings of anatomy, gross anatomy, neuroanatomy and neuroscience, human physiology, exercise physiology, psychology, chemistry and physics content were quantified. Main outcome measures include frequencies and distributions of courses in each subject area. Results: We reviewed 309 programs (91.2%) of the total 336 professional programs. Anatomy (91.59%), physiology (88.35%) and exercise physiology (92.56%) were most frequently required basic science courses. However, only 4.85% (n=15) of programs have human gross anatomy dissection or prosection in their curricula and just 2.59% (n=8) of athletic training programs require a course in neuroscience/neuroanatomy. Conclusions: Our data demonstrates a gap exists in athletic training education in the area of neuroanatomy/neuroscience content. The BRAIN ( Brain Research through Advancing Innovative Neurotechnologies) Initiative is new federal research and healthcare task-force aimed at revolutionizing the understanding of the human brain. The Sports and Health Research Program is a partnership between the National Institutes of Health and the National Football League to fund sport concussion research. With the future professional degree change eminent, professional and post-professional athletic training education must seriously consider the inclusion of neuroanatomy content. We present several wet-brain specimen and active learning laboratory options that educators may adopt to provide added depth toneuroscience/neuroanatomy knowledge base. Key words: brain, anatomy, education, and neuroscienc

Low-Altitude UAV Imaging Accurately Quantifies Eelgrass Wasting Disease From Alaska to California

Declines in eelgrass, an important and widespread coastal habitat, are associated with wasting disease in recent outbreaks on the Pacific coast of North America. This study presents a novel method for mapping and predicting wasting disease using Unoccupied Aerial Vehicle (UAV) with low-altitude autonomous imaging of visible bands. We conducted UAV mapping and sampling in intertidal eelgrass beds across multiple sites in Alaska, British Columbia, and California. We designed and implemented a UAV low-altitude mapping protocol to detect disease prevalence and validated against in situ results. Our analysis revealed that green leaf area index derived from UAV imagery was a strong and significant (inverse) predictor of spatial distribution and severity of wasting disease measured on the ground, especially for regions with extensive disease infection. This study highlights a novel, efficient, and portable method to investigate seagrass disease at landscape scales across geographic regions and conditions

A giant planet undergoing extreme-ultraviolet irradiation by its hot massive-star host

The amount of ultraviolet irradiation and ablation experienced by a planet depends strongly on the temperature of its host star. Of the thousands of extrasolar planets now known, only six have been found that transit hot, A-type stars (with temperatures of 7,300-10,000 kelvin), and no planets are known to transit the even hotter B-type stars. For example, WASP-33 is an A-type star with a temperature of about 7,430 kelvin, which hosts the hottest known transiting planet, WASP-33b (ref. 1); the planet is itself as hot as a red dwarf star of type M (ref. 2). WASP-33b displays a large heat differential between its dayside and nightside, and is highly inflated-traits that have been linked to high insolation. However, even at the temperature of its dayside, its atmosphere probably resembles the molecule-dominated atmospheres of other planets and, given the level of ultraviolet irradiation it experiences, its atmosphere is unlikely to be substantially ablated over the lifetime of its star. Here we report observations of the bright star HD 195689 (also known as KELT-9), which reveal a close-in (orbital period of about 1.48 days) transiting giant planet, KELT-9b. At approximately 10,170 kelvin, the host star is at the dividing line between stars of type A and B, and we measure the dayside temperature of KELT-9b to be about 4,600 kelvin. This is as hot as stars of stellar type K4 (ref. 5). The molecules in K stars are entirely dissociated, and so the primary sources of opacity in the dayside atmosphere of KELT-9b are probably atomic metals. Furthermore, KELT-9b receives 700 times more extreme-ultraviolet radiation (that is, with wavelengths shorter than 91.2 nanometres) than WASP-33b, leading to a predicted range of mass-loss rates that could leave the planet largely stripped of its envelope during the main-sequence lifetime of the host star

After coal: Affective-temporal processes of belonging and alienation in the deindustrializing Nottinghamshire coalfield, UK

This article advances conceptualizations of belonging and alienation among deindustrializing people toward (i) pluralistic temporal and (ii) affective processes. The focus is on belonging and alienation among a deindustrialized generation in the Nottinghamshire coalfield, UK, exploring how various affective-temporal processes mediate capacities, claims, and senses of belonging and alienation. Extant studies suggest that multiple temporal processes constitute deindustrialized places, particularly intergenerational transmissions, declarative memory, and place-histories. Recent work has explored the affective, emotional, and embodied dynamics of these temporal processes. While these literatures are insightful in locating affective and temporal processes of belonging, studies do not have much to say on the relational dynamics of affective-temporal processes in everyday becoming lives and experiences of deindustrializing places. The significance of foregrounding multiple affective-temporal processes of belonging and alienation is because of their relational nature. Advancing understandings of belonging is critical as a coherent sense of belonging is fundamental for individual and social well-being, and the loss of belonging, namely, alienation, informs how former industrial places are lived. Based on autoethnographic, interview and Observant Participation research with participants born between 1984 and 1994, I use ethnographic vignettes to delineate multiple relating affective-temporal processes of belonging and alienation of a generation that came after coal. The first vignette concerns the embodied and affective relationalities of intergenerational transmission and becoming in a deindustrialized world through the lens of masculinity, place and belonging. The second vignette examines nostalgic and traumatic shared declarative memories contingent of living through and with deindustrialization. The third vignette looks at intersections of place histories, silenced memory and local pride and shame, drawing out the significance of space and place to class-based experiences. Weaved through the stories are thematic threads of class, place, alienation, belonging, and temporality. Bringing these threads together, the paper then discusses the relationalities between issues covered, emphasizing the mutual contingencies between affective-temporal processes of belonging and alienation. I end by calling for shared affective-temporal processes of belonging and alienation to form the basis of a renewed solidarity, attenuation of alienation and a means to belong

The First Post-Kepler Brightness Dips of KIC 8462852

We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometric surveillance started in October 2015, and a sequence of dipping began in 2017 May continuing on through the end of 2017, when the star was no longer visible from Earth. We distinguish four main 1-2.5% dips, named "Elsie," "Celeste," "Skara Brae," and "Angkor", which persist on timescales from several days to weeks. Our main results so far are: (i) there are no apparent changes of the stellar spectrum or polarization during the dips; (ii) the multiband photometry of the dips shows differential reddening favoring non-grey extinction. Therefore, our data are inconsistent with dip models that invoke optically thick material, but rather they are in-line with predictions for an occulter consisting primarily of ordinary dust, where much of the material must be optically thin with a size scale <<1um, and may also be consistent with models invoking variations intrinsic to the stellar photosphere. Notably, our data do not place constraints on the color of the longer-term "secular" dimming, which may be caused by independent processes, or probe different regimes of a single process
