Evaluating Small Uas Operations And National Airspace System Interference Using Aeroscope, Ryan J. Wallace, Kristy M. Kiernan, Tom Haritos, John Robbins, Jon M. Loffi

Journal of Aviation Technology and Engineering

A recent rash of near mid-air collisions coupled with the widespread proliferation of small unmanned aircraft systems (sUAS) raise concerns that integration is posing additional risk to the National Airspace System. In 2016, sUAS sighting reports by manned aircraft pilots averaged 147 per month. In the first three quarters of 2017, sUAS sightings jumped to 188 per month. The purpose of this study was to evaluate sUAS operator behavior to determine potential interference with aviation operations. While previous research has indeed yielded findings about operator behavior, such studies were generally based on data derived from Aviation Safety Reporting System filings …

A Critical Appraisal Of The Dark Triad Literature And Suggestions For Moving Forward, Joshua D. Miller, Colin E. Vize, Michael L. Crowe, Donald R. Lynam

Department of Psychological Sciences Faculty Publications

Since its introduction in 2002, dark-triad research—the simultaneous study of psychopathy, narcissism, and Machiavellianism—has exploded, with the publication of hundreds of peer-reviewed articles, books, and chapters, as well as coverage by the lay media. Unfortunately, several limitations to this research are unrecognized or ignored. These limitations include (a) the treatment of dark-triad constructs as unidimensional, contrary to evidence for their multidimensionality; (b) the indistinctness between current measures of Machiavellianism and psychopathy; (c) the use of multivariate statistical approaches that pose statistical and interpretive difficulties; (d) failure to test dark-triad relations directly against one another; and (e) methodological concerns related to …

Urban Underground Infrastructure Monitoring Iot: The Path Loss Analysis, Abdul Salam, Syed Shah

An Underground Radio Wave Propagation Prediction Model For Digital Agriculture, Abdul Salam

Computer Information Technology Faculty Publications

Underground sensing and propagation of Signals in the Soil (SitS) medium is an electromagnetic issue. The path loss prediction with higher accuracy is an open research subject in digital agriculture monitoring applications for sensing and communications. The statistical data are predominantly derived from site-specific empirical measurements, which is considered an impediment to universal application. Nevertheless, in the existing literature, statistical approaches have been applied to the SitS channel modeling, where impulse response analysis and the Friis open space transmission formula are employed as the channel modeling tool in different soil types under varying soil moisture conditions at diverse communication distances …

Le Personnel Est Politique: Médias, Esthétique Et Politique De L'Autofiction Chez Christine Angot, Chloé Delaume Et Nelly Arcan, Mercédès Baillargeon

Purdue Studies in Romance Literatures

Regardant les questions de témoignage, de confession, de traumatisme, de sexualité et de violence dans les œuvres (semi-)autobiographiques, ce livre explore la co-construction d’identités personnelles et collectives par des femmes écrivains à l’ère des médias et de l’autoreprésentation. À une époque où la littérature française est souvent accusée d'être égocentrique et trop narcissique, Mercédès Baillargeon avance que l’autofiction des femmes a été reçue avec controverse depuis le tournant du millénaire parce qu’elle perturbe les idées reçues à propos des identités nationale, de genre et de race, et parce qu’elle questionne la distinction entre fiction et autobiographie. En effet, ces écrivaines …

Structural Damping By Layers Of Fibrous Media Applied To A Periodically-Constrained Vibrating Panel, Yutong Xue, J Stuart Bolton, Thomas Herdtle, Seungkyu Lee, Ronald W. Gerdes

Publications of the Ray W. Herrick Laboratories

It has recently been demonstrated that layers of fibrous, "acoustical" material can effectively damp structural vibration in the sub-critical frequency range. In that frequency range, the acoustical near-field of a panel consists of oscillatory flow oriented primarily parallel with the panel surface. When a fibrous layer occupies that region, energy is dissipated by the viscous interaction of the near-field and the fibrous medium, and the result is a damping of the panel motion. Previously, the damping effect has been demonstrated to occur for line-driven, infinite panels and panels with isolated constraints. In this article, the focus is instead on periodically-constrained …

General Aviation Hypoxia And Reporting Statistics, Timothy Holt, Jacqueline Luedtke, Jennah Perry, Michelle Hight, Claire Schindler, Pamela Ward

Journal of Aviation Technology and Engineering

Hypoxia is defined as a lack of oxygen throughout the body, which can be caused by several factors at any altitude. General aviation (GA) pilots may argue that most GA aircraft cannot attain the required altitudes where one might be more affected by hypoxia, but it is exactly that attitude that may makes pilots more susceptible to hypoxia. The impact of this hazardous attitude is even more apparent if one considers that out of the 590,038 certificated pilots in the USA, a little over 30% of them are GA pilots (FAA, 2015). The problem is that unlike airline pilots or …

Child Maltreatment Disclosure To A Text Messaging-Based Crisis Service: Content Analysis, Laura Schwab-Reese, Nitya Kanuri, Scottye Cash

Purdue University Libraries Open Access Publishing Fund

Background: Disclosure is a difficult but important process for victims of child maltreatment. There is limited research on child maltreatment disclosure. Young people have been reluctant to disclose victimization to adults, but short message service (SMS) crisis services may represent one novel method of engaging young people around sensitive topics.

Objective: The purpose of this study was to determine characteristics of child maltreatment disclosure to an SMS-based crisis service.

Methods: We conducted a content analysis of all conversations (N=244) that resulted in a mandatory report by an SMS-based crisis service between October 2015 and July 2017. We coded characteristics of …

Indiana Tpims, Donna Luley

Purdue Road School

This session provides a construction and go-live update on the Truck Parking Information Management System (TPIMS). Safe, convenient parking is essential for long-haul truck drivers, the lifeblood of our freight transportation network. Yet drivers often struggle for up to an hour each day to find areas to safely rest. That’s why eight states—Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Ohio, and Wisconsin—have joined together to develop this real-time, multistate system.

Lessons Learned From An International Airport Safety Competition: A Risk Analysis Approach, Caroline Marete, Mary E. Johnson

Purdue Road School

According to the Flight Safety Foundation, about 27,000 ramp accidents and incidences occur annually. These accidents and incidences affect airport operations, result in personnel injuries, and damage aircraft, facilities, and ground support equipment. Purdue students participated in the 2018 Air Transport and Aeronautics Education and Research Association (ATAERA) safety competition to improve airport safety at Kigali International Airport in Rwanda. This presentation focuses on the practical use of risk analysis and proposed solutions.

Incidence Of An Astronaut Not Sealing The Pressure Garment Visor On Reentry, Cameron M. Smith, Trent Tresch

Journal of Human Performance in Extreme Environments

Audiovisual records of a Project Mercury pilot’s activities during an orbital flight indicate that his visor was left open during reentry and descent to the sea surface, phases of flight during which cabin pressure loss was to be mitigated by suit pressurization; however, the suit could not have been pressurized with the visor open. Thus, for a presently unknown reason, a critical safety step—sealing the visor and making a pressure suit integrity test before reentry—was overlooked in this flight. Later, Space Shuttle flights were carried out with visors unsealed for much of the launch and landing phases, with the false …

Shoulders....Not Just For Snow Storage, Emilie Worley, Brian Toombs

Hard shoulder running (HSR) is an innovative strategy for squeezing additional capacity out of existing infrastructure, targeting facilities with short-duration peak periods where congestion is noticeable. Using the recent HSR design completed in Ohio, conversations with state DOTs that have implemented HSR, and a tour of Michigan’s HSR corridor, this presentation defines what HSR is, details the safety analysis requested by FHWA, and provides lessons learned during design and implementation.

Vulnerability And Resistance In Carmen Aguirre’S Mexican Hooker #1, Cinta Mesa

CLCWeb: Comparative Literature and Culture

In her article, “Vulnerability and Resistance in Carmen Aguirre’s Mexican Hooker#1,” Cinta Mesa examines Chilean-Canadian playwright and actress Carmen Aguirre’s latest autobiographical novel, Mexican Hooker#1, to analyze Latina vulnerability in relation to exile, emigration, gender violence and stereotypes. The article relies upon Judith Butler’s definition of vulnerability (20), which is excluded from official texts. The consequences of these types of trauma, which are written on female bodies, are expressed through post-traumatic stress disorder. The author expresses the difficulty of acting because of her post-traumatic stress disorder symptoms and the challenges she meets on her way to heal herself and …

Motherhood, Vulnerability And Resistance In The Elysium Testament By Mary O’Donnell, María Elena Jaime De Pablos

CLCWeb: Comparative Literature and Culture

Mary O’Donnell’s novel The Elysium Testament (1999) narrates the story of Nina, an accomplished grotto restorer, but a neglectful wife and mother according to the Irish patriarchal symbolic order –the “register of regulatory ideality” (Butler, Bodies that Matter 18). Estranged from her husband, Neil, she sends him a series of letters, her “testament,” where some of the most significant aspects of her life are exposed. Readers discover that Nina’s and Neil’s marriage begins to crumble after the birth of their second child, Roland, to whom Nina attributes a frightening dual nature, which she tries to control through physical and psychological …

Chase Riboud’S Hottentot Venus (2003) And The Neo-Victorian: The Problematization Of South-Africa And The Vulnerability And Resistance Of The Black Other, Maria Isabel Romero Ruiz

CLCWeb: Comparative Literature and Culture

This article touches upon issues of captivity, suppression, misrepresentations and exclusion of black people from a historical and cultural point of view through the analysis of Chase-Riboud’s neo-Victorian novel Hottentot Venus (2003). It also focuses on the implications and consequences for contemporary South Africa of situations of slavery and exploitation of African descended peoples. Notions of identity and moral and legal inclusion of black women into past and contemporary societies and communities will be also discussed from the point of view of postcolonial and gender and sexuality studies. The complexities of blackness and the violation of human rights as a …

Sex Between Women And Indianness: Vulnerable Casted Bodies, Antonia Navarro-Tejero

CLCWeb: Comparative Literature and Culture

In her essay, "Sex Between Women and Indianness: Vulnerable Casted Bodies," Antonia Navarro-Tejero examines the lesbian experience, using two heterosexual voices representing the lesbian abject: Shobha Dé’s popular bestseller novel Strange Obsession (1992) and Karan Razdan’s Bollywood film Girlfriend (2004), as they espouse the dominant ideology of heteronormativity, rendering homosexuality as a western illness that taints the Indian culture. First, the author provides an overview of the history of lesbian desire in India, and how it is rendered by Hindu nationalists. Then, following the postulates of Michel Foucault, she analyzes both cultural texts with respect to how same-sex desire is …

Memory In T/Rubble: Tackling (Nuclear) Ruins, Marilena Parlati

CLCWeb: Comparative Literature and Culture

The 1945 bombs at Hiroshima and Nagasaki seem to have recently started to recede back in the memory of Western culture. 9/11 and the age of global warfare which we are in have averted our gazes away from that past, in our tremulous expectations of the next traumatic event. In the twentieth century, poets like Tony Harrison have tackled this delicate topic, while Japanese culture has in many ways been forced and willing to reconsider its own agendas and sense of identity from those ‘ground zeroes’ onwards. In both A Pale View of Hills (1982) and An Artist of the …

The Commodified Body And Post/In Human Subjectivities In Frears’S Dirty Pretty Things And Romanek’S Never Let Me Go, Rocio Carrasco

CLCWeb: Comparative Literature and Culture

Following new materialist analysis, this article takes the body as the central locus of analysis, and relates it to broader questions such as ethics, ideology, power and/or technologies. Specifically, it revolves around the idea of embodied subjectivity as articulated by scholars Rosi Braidotti, Sherryl Vint or Cary Wolfe, whereby body and subjectivity are indissolubly and interestingly connected. Stephen Frears’s Dirty Pretty Things (2002) and Mark Romanek’s Never Let Me Go (2010) exploit the idea of the commodified body, understood here as a vulnerable body, a disposable commodity at the service of powerful and/or wealthy people. Victims of the cruelties inflicted …

Subverting Transnormativity: Rage And Resilience In Kim Fu’S For Today I Am A Boy, Andrea Ruthven

CLCWeb: Comparative Literature and Culture

This article analyzes the affective politics of rage and resilience in the novel For Today I Am a Boy (2014) by Kim Fu. The novel explores the dis-identification (Muñoz 1999) of gender identity through the protagonist, focusing on the rage, sadness, fear, and secrecy that function as the glue holding the body together, but that also work to constrain the process of self-identification. The novel is not the celebration of self-realization, nor is it the lamentation of a traumatized protagonist. Instead, the narrative pays attention to the various ways in which non-binary, or non-normative gender identities are marginalized, and to …
