To speak or not to speak - A multiple resource perspective

The desirability of employing speech response in a dynamic dual task situation was discussed from a multiple resource perspective. A secondary task technique was employed to examine the time-sharing performance of five dual tasks with various degrees of resource overlap according to the structure-specific resource model of Wickens (1980). The primary task was a visual/manual tracking task which required spatial processing. The secondary task was either another tracking task or a spatial transformation task with one of four input (visual or auditory) and output (manual or speech) configurations. The results show that the dual task performance was best when the primary tracking task was paired with the visual/speech transformation task. This finding was explained by an interaction of the stimulus-central processing-response compatibility of the transformation task and the degree of resource competition between the time-shared tasks. Implications on the utility of speech response were discussed.

Measured influence of overhead HVAC on exposure to airborne contaminants from simulated speaking in a meeting and a classroom

Tracer gas experiments were conducted in a 158 m 3 room with overhead supply diffusers to study dispersion of contaminants from simulated speaking in physically distanced meeting and classroom configurations. The room was contained within a 237 m 3 cell with open plenum return to the HVAC system. Heated manikins at desks and a researcher operating the tracer release apparatus presented 8-9 thermal plumes. Experiments were conducted under conditions of no forced air and neutral, cooled, or heated air supplied at 980-1100 cmh, and with/out 20% outdoor air. CO 2 was released at the head of one manikin in each experiment to simulate small (< 5 µm diameter) respiratory aerosols. The metric of exposure relative to perfectly mixed (ERM) is introduced to quantify impacts, based on measurements at manikin heads and at three heights in the center and corners of the room. Chilled or neutral supply air provided good mixing with ERMs close to one. Thermal stratification during heating produced higher ERMs at most manikins: 25% were ≥ 2.5 and the highest were > 5× perfectly mixed conditions. Operation of two within-zone air cleaners together moving ≥400 cmh vertically in the room provided enough mixing to mitigate elevated exposure variations.

Do Research Software Engineers and Software Engineering Researchers Speak the Same Language?

Anecdotal evidence suggests that research software engineers (RSEs) and software engineering researchers (SERs) often use different terminologies for similar concepts, creating communication challenges. To better understand these divergences, we have started investigating how software engineering fundamentals from the SER community are interpreted within the RSE community, identifying aligned concepts, knowledge gaps, and areas for potential adaptation. In conclusion, our preliminary findings reveal opportunities for mutual learning and collaboration, and our systematic methodology for terminology mapping provides a foundation for a crowdsourced extension and validation in the future.

MS-SPEAK: Final Report and Implementation Roadmap

This report describes the scope and results of a project undertaken to help consumer-owned electric utilities improve the cybersecurity of their system interfaces. The team developed a cybersecurity reference architecture for the MultiSpeak interoperability standard, which is used by many of these consumer-owned utilities and their supporting vendors. The analysis and use cases focused on the Remote Connect/Disconnect (RCD) interface, and its vulnerabilities. An open-source toolkit has also been developed to facilitate customized intrusion detection systems (IDS) for MultiSpeak applications. This report includes a roadmap for others to use and customize this IDS toolkit for additional MultiSpeak versions and interfaces.

Speaking Volumes About 3-D

In 1999, Genex submitted a proposal to Stennis Space Center for a volumetric 3-D display technique that would provide multiple users with a 360-degree perspective to simultaneously view and analyze 3-D data. The futuristic capabilities of the VolumeViewer(R) have offered tremendous benefits to commercial users in the fields of medicine and surgery, air traffic control, pilot training and education, computer-aided design/computer-aided manufacturing, and military/battlefield management. The technology has also helped NASA to better analyze and assess the various data collected by its satellite and spacecraft sensors. Genex capitalized on its success with Stennis by introducing two separate products to the commercial market that incorporate key elements of the 3-D display technology designed under an SBIR contract. The company Rainbow 3D(R) imaging camera is a novel, three-dimensional surface profile measurement system that can obtain a full-frame 3-D image in less than 1 second. The third product is the 360-degree OmniEye(R) video system. Ideal for intrusion detection, surveillance, and situation management, this unique camera system offers a continuous, panoramic view of a scene in real time.

Clear Speaking about Machines: People are Exploring Mars, Not Robots

The primary responsibility of all scientists is to ensure the integrity of their work. For cognitive and social scientists, this means first and foremost preserving clarity about what we know about people, and not allowing descriptions of technology to demean or obscure the reality of how people think, behave, and live. Without this clarity, engineering requirements analyses, tool design, and evaluations of people will be confused. A sharp, uncompromising understanding about the nature of people is essential if we are to design and fit new technologies that are appropriate and successful for NASA's mission operations.

Launch Risk Acceptability: The Public Speaks

The perspective of those assuming risk has become increasingly important to launch agencies. The IAASS white paper "An ICAO for Space?" proposed four ultimate goals of any international regulatory framework. The first of these was to "Ensure that citizens of all nations are equally protected from "unreasonable levels" of risk from overflight by missiles, launch vehicles and returning spacecraft". A key component of this concept is the issue of what is an "unreasonable level" of risk from the perspective of those assuming the risk.

Let’s speak FRETish

FRET (https://github.com/NASA-SW-VnV/fret [github.com]) is a framework for the elicitation, formalization and analysis of requirements. FRET allows its user to enter requirements in a structured natural language called FRETish. Requirements written in FRETish are assigned unambiguous semantics. FRET supports its users in understanding this semantics and repairing requirements if applicable, by utilizing a variety of forms for each requirement: natural language description, formal mathematical logics, diagrams, and interactive simulation. FRET exports requirements into forms that can be used by a variety of analysis tools, including state-of-the-art model checkers and runtime monitoring tools. The talk will cover some of the theory behind the framework, present case studies from the aerospace and robotics domains, as well as current work on extending FRET for specifying requirements for software that learns.

A Picture Speaks 360,000 Words - Virtual Reality as a Decommissioning Planning Tool - 19364

Whiteshell Laboratories, located in Manitoba, Canada, provided research facilities for the Canadian nuclear industry since the early 1960's. Decommissioning of Whiteshell Laboratories has been ongoing since 2002 under Atomic Energy of Canada (AECL) and, more currently, since 2015 under the WL Closure Project managed by Canadian Nuclear Laboratories (CNL). One of the key steps to ensuring safe decommissioning operations is effective planning, including pre-job briefings, and post-job verification and review. Effective planning involves clear and concise communication of the field conditions, system configurations, hazards, and task goals or achievements to front line employees, and task approvers and verifiers. In many instances, employees can enter, view, inspect, verify or otherwise familiarize themselves with the task and task location. However, in several cases, hazardous conditions in the task location make it difficult for employees to easily access the location themselves, due to hazardous conditions, PPE requirements, training qualification gaps or space limitations. Since 2016, 360 deg. cameras have been used to create a virtual 'tour' of the hazardous task locations at Whiteshell Laboratories, which can be viewed by one or all of the employees involved in a task, from a position of safety. This allows a task to be discussed with all employees involved without the need for added risk of exposure to dose or industrial hazards or costly PPE, and supports ALARA control techniques of removing the hazard by moving work planning walk downs away from hazardous locations and guarding the worker by limiting the time a worker is exposed to the hazard. This paper provides an overview of the technologies used to capture and present the 360 virtual tours, the benefits from a safety, schedule and cost perspective, and the limitations of the current implementation that could be improved upon in a future iteration.

Risk

Speaking up, i.e. expressing ones concerns, is a critical piece of effective communication. Yet, we see many situations in which crew members have concerns and still remain silent. Why would that be the case? And how can we assess the risks of speaking up vs. the risks of keeping silent? And once we do make up our minds to speak up, how should we go about it? Our workshop aims to answer these questions, and to provide us all with practical tools for effective risk assessment and effective speaking-up strategies..

Research and development of a versatile portable speech prosthesis

The Versatile Portable Speech Prosthesis (VPSP), a synthetic speech output communication aid for non-speaking people is described. It was intended initially for severely physically limited people with cerebral palsy who are in electric wheelchairs. Hence, it was designed to be placed on a wheelchair and powered from a wheelchair battery. It can easily be separated from the wheelchair. The VPSP is versatile because it is designed to accept any means of single switch, multiple switch, or keyboard control which physically limited people have the ability to use. It is portable because it is mounted on and can go with the electric wheelchair. It is a speech prosthesis, obviously, because it speaks with a synthetic voice for people unable to speak with their own voices. Both hardware and software are described.
