A Digital Classification System to Assess Project Failures
Abstract:
Failure classification schemes are often used to categorize events that cause failures in projects. Despite the frequent publication of studies on project failure and success classification, there has been no analysis of failure classification schemes. Specifically, an open question concerns the similarities and differences of failure classification schemes between and within disciplines. Answering this question will provide insight into the applicability of a scheme across a range of disciplines and the challenges that may exist when multiple disciplines are collaborating on a project. Understanding the contents and nature of failure classification schemes is critical to improving theoretical study and practical implementation of schemes on projects.
The research presented in this presentation identifies 400 failure classification schemes through a systematic review, extracts over 4000 perceived causes of failure from the schemes as meta-data, and analyzes the schemes with a focus on disciplinary differences in the perceived causes of failure. Meta-analysis of the perceived causes of failure in the 400 failure classification schemes identifies that the content of failure classification schemes are diverse, both within and across disciplines. Significant differences are shown between schemes used in different disciplines. Within disciplines, the schemes show patterns in the perceived causes of failure that appear most frequently and there are some common perceived causes of failure among many disciplines. The findings of the research conclude that caution must be taken if applying a scheme across multiple disciplines.

Accelerating the Innovation Cycle of Nanophotonic Systems Design
Abstract:
The general process for nanophotonics systems innovation involves identifying/generating a new concept, proposing a device design that can capture the concept, and validating the device design with an electromagnetic simulator. The latter two steps are typically performed iteratively by a researcher with specialized domain knowledge until a satisfactory device is identified, thereby requiring significant expenditure in time and computational cost. We will discuss computational algorithms based on deep neural networks that can accelerate the design and simulation of nanophotonic devices.
We will discuss the use of generative networks to perform population-based optimization and elucidate how the neural network architecture can be tailored to effectively search for the global optimum in a non-convex design landscape. We will also discuss how physics-informed deep networks can be trained with a combination of data and physical constraints to serve as accurate surrogate electromagnetic solvers. We anticipate that the ability for deep learning models to accelerate and even automate the simulation and design of photonic systems will push the innovation cycle of photonics research in academia and industry.

Creativity - A Human Factors Challenge
Our world is changing rapidly, and work follows suit. Considering the traditional division of work in physical and mental labor, it is primarily physical labor that has been systematically analyzed and optimized over the last century. This made it possible to break down many manual tasks into small entities that could eventually be automated. This widespread automation is one of the main drivers of a changing world of work. While non-routine tasks have been considered fairly safe from automation in the past, recent advances in cognitive computing and artificial intelligence suggest that mental work might be next in line. In fact, some basic cognitive tasks have already been automated. A final frontier on the road towards ubiquitous automation, however, seems to be the generation of creative ideas. This suggests that the human capability to create will become increasingly important.
The present talk therefore aims to characterize creativity and its role in the modern workplace. Starting form a shared understanding of what creativity is, we examine the different areas in which human factors/ergonomics can support creative work. More specifically, we take stock in how creativity can be measured, analyze the pitfalls these types of measurement entail, and show how creativity support systems are now a staple in HMI Design. Concluding, human factors/ergonomics is recognized as particularly suited discipline to tackle creativity measurement and amplification in a human-centered way.

Electromagnetic Thermocouple (TC) Anomaly Mechanisms During Atmospheric Entry
Thermocouples (TCs) are a critical diagnostic sensor for high enthalpy environments including Thermal Protection Systems (TPS) for atmospheric entry, hypersonic wind tunnels, and arc jet test facilities. They are used for both evaluating facility environmental conditions (enthalpy, and heat flux) as well as for measuring in-situ material thermal response under test conditions (thermal conductivity, heat capacity, etc.). Consequently, accurate TC measurements are fundamental for both material and facility Verification and Validation (V&V). However, a number of electromagnetic TC anomalies have been observed in both ground tests and flight instrumentations. These anomalies are caused via various coupling mechanisms: surface voltage coupling, Hall effect currents, and RF rectification. All of these mechanisms can, if unaddressed, result in obviously compromised results or worse, non-physical measurements which appear reasonable. This talk will provide an overview of each of these anomaly mechanisms and discuss ongoing efforts to quantify and mitigate them.

Facilitating (and not Interfering with) Work System Resilience with New Technology
Traditionally, the negative unintended consequences of introducing new technologies into complex systems have not been explicitly assessed and mitigated. Recently, our understanding of how to identify, protect, and facilitate sources of resilience in a work system has advanced. In particular, there are lessons learned from two case studies of technologies: 1) voice loops, an auditory shared space that supported NASA Johnson communication and coordination, and 2) the introduction of bar coding in the medication administration process throughout the Veteran’s Health Administration. BCMA was designed to improve patient safety by reducing medication errors at the time of medication administration.
During and after implementation, there were unintended consequences on the ability of work systems to: 1) have a shared awareness of demands and deviations, 2) progressively respond to changing circumstances, 3) guide local control with policies and procedures, 4) flexibly adapt by reducing constraints on actions, and 5) coordinate across the system.

Abstract:
“Spacecraft large enough for crew to move around inside them have traditionally used handrails and foot restraints to enable crew mobility. The mass of this hardware can become significant in large spacecraft such as the Common Habitat. Additionally, handrails and foot restraints in a multi-gravity habitat are trip hazards when the habitat is in a gravity environment. Further, ISS crew have noted risks of breaking ankles and wrists when using handrails for translation and have noted places where not enough handrails are present. Robotic gecko-derived grippers developed by JPL to retrieve satellites can be adapted to crew-worn pads that can adhere to surfaces to enable crew translation in microgravity.
This technology will help to eliminate the need for handrails and foot restraints for mobility in crewed microgravity spacecraft cabins. It has the potential to achieve significant mass reductions in future space habitats, with application to suborbital flight, LEO, cislunar space, interplanetary space, the Moon, and Mars. Additionally, it can prevent crew injury and discomfort. Project goals and objectives are to prepare gecko uniform prototypes for use in multi-gravity testing and conduct initial investigations into human factors of postures and motions needed for intravehicular activity (IVA) translation and restraint in multiple gravity environments, without the use of handrails or foot restraints. Gecko grippers have been tested for use as robotic end effectors terrestrially, on microgravity aircraft, and aboard the ISS.
Using the grippers as a body-mounted system to achieve IVA crew mobility is a new application that has not been pursued outside of this effort. This work will continue paper studies performed by NASA student interns by developing physical prototypes of spacecraft crew uniforms with gecko-derived body-mounted grippers. Clothing prototypes may include long sleeves, short sleeves, long pants, shorts, gloves, and/or booties equipped with gecko gripper pads. Forward work is to test these uniforms in a 1g environment to verify that the design does not introduce obstructions, trip hazards, or other consequences when used in terrestrial gravity. Based on the 1g test results, the uniform prototypes will be refined, and a test plan developed for testing at 0g, (1/6)g, and (3/8)g.

Generation Y Perspectives
Discipline: Environmental Control/Life Support
Are you familiar with the famed Generation Y, or “Gen Yers?” Generation Y is projected to be 47 percent of the workforce by 2014. They were born roughly between 1977 and 2000, but that is definitely not their only defining factor. But who is this group, and what do they have to do with the future of the space program and the Johnson Space Center (JSC)? During 2007, a group of Gen Yers at JSC participated on a committee to address the NASA Headquarters strategic communications plan. Garret Fitzpatrick, along with his co-authors, created a presentation to share the Gen Yers’ perspective on their generation in conjunction with the strategic communications strategy released. This knowledge capture (KC) event is that presentation.

Getting Better at Getting Better: Caring and Candor in Feedback Conversations
Simultaneously improving performance and relationship in feedback conversations can be challenging. It is easier to focus just on performance (with confronting feedback that can harm the relationship) or just on the relationship (by sugar-coating the feedback). This session draws on cross-industry insights from research on learning from accident and error in high-hazard chemical processing and nuclear power, and on feedback and debriefing challenges in clinical care. The session illuminates 1) why it is so hard to hold the polarities of candor and caring at the same time, 2) the internal “ninja mind-training” needed to do so, and 3) a method of advocating for one’s own point of view while exploring other people’s that can be used advance learning and performance in conversation or email. The session blends didactic and experiential approaches to understanding and mastering the approach.

Inspection Considerations from the ISS Program
Discipline: Nondestructive Evaluation
The International Space Station Program has maintained a permanent human presence in space since November, 2000. Through the assembly of the vehicle, multiple on-orbit anomalies, and now the transition to full utilization many needs for inspection techniques have been identified. Some of these needs have been satisfied and others remain desired capabilities. An overview of the types of inspections needed, such as visual indications, measurement of structural damage, and thermal performance, will be discussed. Key risks that define inspection methods as part of the mitigation plan will be summarized, along with methods we use to demonstrate these techniques both for ISS needs as well as looking forward to Exploration capabilities using the ISS as a demonstration platform.

Integrated Photonics and Nanophotonic Devices Using Transparent Conductive Oxides
Transparent conductive oxide (TCO) materials have attracted tremendous research interests for integrated photonics and nanophotonic devices in recent years due to the extraordinary perturbation to the refractive indices achieved either through oxygen vacancy doping or electrical gating. In addition, high quality TCO materials can be deposited using DC- or RF-sputtering on various substrates. Therefore, TCO materials promise unprecedented potentials for heterogeneous integration with silicon photonic integrated circuits (PICs) and nanophotonic platforms.
In this talk, I will review recent research progress in my group for the development of TCO-gated silicon photonic devices to achieve ultra-high energy efficiency, high speed photonic devices, including photonic crystal nanocavity modulators and microring resonators with ultra-large E-O tuning efficiency. We also achieved 5Gbit/s E-O modulation speed and will also discuss the strategy to further improve the energy efficiency to atto-joule/bit and implement large-scale integration for data centers. TCO based metasurface devices will also be discussed with envisioned applications in optical filtering and beam control.

Launch, Entry & Abort, Intra-Vehicular Spacesuits
Discipline: Environmental Control/Life Support
Kenneth Thomas, senior spacesuit expert, presented information about Launch, Entry & Abort (LEA) spacesuits–part of an overall vehicle crew escape and survival system. These LEA spacesuits are worn during the launch and reentry to enhance crew survival. The U.S. has traditionally called these spacesuits Intravehicular Activity (IVA) spacesuits. The Russians refer to this type of spacesuit as “Rescue Suits.” Thomas discussed the success of the LEA suits and the consequences of eliminating their use or providing inadequate systems.

Microfluidic Sensing Systems to Study and Seek Microbes Beyond Earth
Abstract:
We develop miniaturized integrated bio/analytical instruments and platforms to conduct economical, frequent, autonomous life-science experiments in outer space. The technologies of our multiple “free-flyer” cubesat missions are the basis of a rapidly growing suite of miniaturized biologically- and chemically-oriented instrumentation now enabling a new generation of in-situ space science experiments. Over the past decade, our missions have included studies of space-environment-related changes in gene expression, drug dose response, microbial longevity and metabolism, and the degradation of biomarker molecules. The science and technology of the GeneSat (2006) and BioSentinel (2022, via Artemis-1) missions will be highlighted in the context of conducting biological and chemical experiments in outer space using miniaturized integrated systems.
We also adapt and apply our spaceflight-compatible microfluidic and bioanalytical technologies to the challenge of finding molecular and structural indications of microbial life on the so-called icy worlds of our solar system, particularly the moons Enceladus and Europa. The Sample Processor for Life on Icy Worlds (SPLIce) system, a microfluidic sample-processing “front end” to enable autonomous detection of signatures of life and measurements of habitability parameters on icy worlds, will be described. SPLIce is under development to support several mission scenarios, including a fly-through of Enceladus’ icy plumes, expected to yield ~ 2 µL of ice particles, and a Europan lander, the sampling system of which is anticipated to deliver 1 – 5 mL of icy solids for analysis.

Thermal Glove Wrist-Hand Orthoses and Rheumatoid Arthritis
Rheumatoid arthritis (RA) is an autoimmune disease affecting nearly 1% of the world’s population with symptoms such as inflammation, pain, and reduced strength. Physicians and scientists work to develop pharmaceuticals and medical devices aimed at decreasing the symptoms associated with RA to better the lives of those affected. One of the most recent developments is the addition of thermal therapy gloves to the array of upper limb orthoses available to patients with RA. It was hypothesized that this study will show that orthoses in the form of thermal therapy gloves are beneficial to the patients by reducing symptoms such as pain and allowing them an increased range of motion and overall hand functionality. Patients in stage 2 were recruited and asked to first complete a personal history survey including the Health Assessment Questionnaire (HAQ) and Pain Catastrophizing Scale (PCS). Range of motion tasks and the Arthritis Hand Function Test (AHFT) were completed to determine the effect of two thermal therapy gloves on the range of motion and activities of daily living. This webcast will give an overview of the pilot study, results, and suggestions for future studies.

Using PZT Sensors for Tank Health Monitoring and Propellant Mass Gauging
Abstract:
The technology in the presentation utilizes a random white noise vibration source to drive a transducer which acts as an actuator with identical transducers used as sensors based on PZT materials. The sensors are recorded and used to produce Frequency Response Functions (FRF) which indicate unique stiffness and mass information for tanks (or other structures) near real-time. The data also shows the level of the fluid with amplitude variations based on the change in vibration transmission coupling as the fluid transverses the inside tank opposite the transducers. All transducers are non-invasive, applied to a tank with adhesive allowing for measurements of many fluids including cryogenic and toxic fluids used on space vehicles. This presentation will describe the unique technology and propellant tank test results including low gravity sub-orbital flights.
