Computer circuit card puller

The invention generally relates to hand tools, and more particularly to an improved device for facilitating removal of printed circuit cards from a card rack characterized by longitudinal side rails arranged in a mutually spaced parallelism and a plurality of printed circuit cards extended between the rails of the rack

Fringe Science: Defringing CCD Images with Neon Lamp Flat Fields

Fringing in CCD images is troublesome from the aspect of photometric quality and image flatness in the final reduced product. Additionally, defringing during calibration requires the inefficient use of time during the night to collect and produce a "supersky" fringe frame. The fringe pattern observed in a CCD image for a given near-IR filter is dominated by small thickness variations across the detector with a second order effect caused by the wavelength extent of the emission lines within the bandpass which produce the interference pattern. We show that essentially any set of emission lines which generally match the wavelength coverage of the night sky emission lines within a bandpass will produce an identical fringe pattern. We present an easy, inexpensive, and efficient method which uses a neon lamp as a flat field source and produces high S/N fringe frames to use for defringing an image during the calibration process.Comment: accepted to PAS

What Lies Beneath: How Paranoid Cognition Explains the Relations Between Transgender Employees\u27 Perceptions of Discrimination at Work and their Job Attitudes and Wellbeing

With the recent public gender transitions of celebrities like Caitlin Jenner, greater visibility of transgender characters on television (e.g., Transparent), and controversial laws enacted in some U.S. states and cities banning transgender employees from accessing bathrooms that align with their gender identities, issues of gender expression have been thrust into the national spotlight. In order to promote greater awareness and acceptance of transgender people, greater knowledge of their life experiences is needed. Adding to a small, but growing, body of research on the work experiences of transgender individuals, the goal of the present study is to examine the cognitive processes that shape these individuals\u27 experiences in the workplace. Drawing on existing theory and research on paranoia, we examine the role of paranoid cognition, defined by hypervigilance, rumination, and sinister attributional tendencies, in explaining the relations between transgender employees\u27 perceptions of workplace discrimination and their job attitudes and psychological wellbeing. Our findings suggest that perceptions of transgender discrimination in the workplace are positively related to paranoid cognition at work; paranoid cognition is positively related to transgender employees\u27 turnover intentions and emotional exhaustion and negatively related to their job satisfaction; and paranoid cognition at work mediates the relations between perceptions of discrimination and each of these outcomes. We conclude by discussing the implications of our results, as well as avenues for future research on the work experiences of transgender employees

Potential Theory on Trees, Graphs and Ahlfors Regular Metric Spaces

We investigate connections between potential theories on a Ahlfors-regular metric space X, on a graph G associated with X, and on the tree T obtained by removing the "horizontal edges" in G. Applications to the calculation of set capacity are given.Comment: 45 pages; presentation improved based on referee comment

From Sanctuary to Home in the Post-Interstate City

The removal of New York Interstate- 81’s (I-81) 1.4 mile stretch of raised, four-lane highway in Syracuse will highlight the critical role of socioeconomics, accessibility, and community building in urban neighborhood reclamation. The removal of what had been previously deemed an urban renewal project, presents Syracuse with new opportunities for space restoration and place-making efforts, atoning for careless and traumatic historic divisions, all the while exploring more substantive design responses tailored to the realities of the City. This thesis explores these fundamental planning considerations through a design lens; by proposing a comprehensive and integrated vision of physical and spatial opportunities provided by the removal of the Viaduct. Through a series of demographic, socioeconomic and spatial analyses, this thesis begins by working to understand the effect of these proposed changes on the communities most directly affected both by I-81’s construction and now its destruction. Then, the thesis examines what it means to be a Sanctuary City in the United States and explores methods in which the vacancy of this land can be found to serve Syracuse’s most disadvantaged and at-risk populations. If Syracuse deems itself a home for everyone, what types of facilities could exist to serve that designation, both built and imagined? In this thesis I propose my own theories about the role of architecture in helping to create a true sense of sanctuary. Finally, the thesis explores the design and programming of a series of buildings, spaces, and urban interventions which serve as a means to this end. In so doing, the thesis critically examines the role of socially integrated urban renewal in Syracuse, NY, and offers design explorations that might mediate social inequities
