Full textAbstract:
We determined whether alerting stimuli cause cutaneous vasoconstriction in conscious rabbits. We compared ear blood flow with renal, mesenteric, and femoral flows at rest and in response to nonnoxious alerting stimuli, which induced theta-rhythm (4-9 Hz) in the simultaneously recorded hippocampal electroencephalogram (EEG). theta-Inducing stimuli (e.g., whistles and fur touches) reduced ear flow by 95 +/- 6%, commencing 1-2 s after the EEG change and lasting 45 s. Renal flow did not significantly change with alerting stimuli, mesenteric and femoral flows slightly decreased, arterial pressure transiently rose (+10 +/- 3 mmHg), and heart rate fell (+43 +/- 9 beats/min). At rest, the coefficient of variation for ear flow (62 +/- 6%) was greater than for other flows (P < 0.01). Phentolamine (1 mg/kg iv) reduced this coefficient to 29 +/- 4% (P < 0.01). Our study demonstrates that alerting responses in conscious rabbits are associated with selective cutaneous vasoconstriction, without increase in flow to skeletal muscle.

Full textAbstract:
The alerting network, a subcomponent of attention, enables humans to respond to novel information. Children with ASD have shown equivalent alerting in response to visual and/or auditory stimuli compared to typically developing (TD) children. However, it is unclear whether children with ASD and TD show equivalent alerting to tactile stimuli. We examined (1) whether tactile cues affect accuracy and reaction times in children with ASD and TD, (2) whether the duration between touch-cues and auditory targets impacts performance, and (3) whether behavioral responses in the tactile cueing task are associated with ASD symptomatology. Six- to 12-year-olds with ASD and TD participated in a tactile-cueing task and were instructed to respond with a button press to a target sound /a/. Tactile cues were presented at 200, 400, and 800 ms (25% each) prior to the auditory target. The remaining trials (25%) were presented without tactile cues. Findings suggested that both groups showed equivalent alerting responses to tactile cues. Additionally, all children were faster to respond to auditory targets at longer cue–target intervals. Finally, there was an association between rate of facilitation and RRB scores in all children, suggesting that patterns of responding to transient phasic cues may be related to ASD symptomatology.

Full textAbstract:
Earthquake-related behaviors in Mexico and Japan have highlighted the need to better understand responses to demanding alerting scenarios. Both countries appear to have benefitted from an established early earthquake warning system for several years. However, recent alert responses documented in these settings have been unlikely to protect residents from death or severe injury. This represents a gap between alerting system investments and effectiveness which, among other implications, could result in very large numbers of avoidable injuries and even deaths. To help better understand and address this gap, the current paper presents a theoretical explanation of why alerted residents have responded in the ways that they did. Behavioral and cognitive theories are discussed towards an integrated but simple model of alert response behavior that can be used to guide further research. Challenges and opportunities for this further research are also outlined.

Full textAbstract:
The purpose of this study was to design an automated mental alerting task that could be utilized when performing vestibular testing on a broad range of patient populations, including certain difficult-to-test populations, such as the hard-of-hearing. A device was developed that utilized vibrotactile stimuli output to two vibrators placed on the subject's left leg, and responded to activation of two momentary pushbuttons controlled by the subjects. Fourteen normal-hearing subjects without history or symptoms of vestibular involvement participated. Each participant underwent three mental-alerting conditions, defined as no task, verbal task, or vibrotactile task. Each condition involved four irrigations of the ear canals, two with warm water and two with cool water. The resultant nystagmus was recorded and analyzed using four measures to compare the effect of the mental alerting task condition. No significant difference was found between verbal and vibrotactile alerting both of which provided better responses than the no alerting task (F=8.443; df=2,13; p=0.001). Between-subjects analysis showed that the number of gaps, which are undesirable periods of absent nystagmus during test recordings, was smallest for the verbal and vibrotactile tasks, and largest for the no task condition. Overall, the results showed that the vibrotactile tasking device (VTD) is an effective alternative means of providing mental alerting during vestibular testing, specifically that of caloric examination.

Full textAbstract:
Minimum Operational Performance Standards (MOPS) are being developed to support the integration of Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS). Input from subject matter experts and multiple research studies have informed display requirements for Detect-and-Avoid (DAA) systems aimed at supporting timely and appropriate pilot responses to collision hazards. DAA alerting is designed to inform pilots of potential threats to “DAA well clear”; the two highest alert levels – caution and warning – indicate how soon pilot action is required and whether there is adequate time to coordinate with the air traffic controller (ATC). Additional empirical support is needed to clarify the extent to which warning-level alerting impacts DAA task performance. The present study explores the differential effects of the auditory and visual cues provided by the DAA Warning alert, and performance implications compared to caution-only alerting are discussed.

Full textAbstract:
Both human and animal studies have demonstrated that respiratory parameters change in response to presentation of alerting stimuli, as well as during stress, yet central neuronal pathways that mediate such responses remain unknown. The aim of our study was to investigate the involvement of the amygdala in mediating respiratory responses to stressors of various intensities and duration. Adult male Wistar rats ( n = 8) received microinjections of GABAA agonist muscimol or saline into the amygdala bilaterally and were subjected to a respiratory recording using whole body plethysmography. Presentation of acoustic stimuli (500-ms white noise, 40–90 dB) caused transient responses in respiratory rate that were proportional to the stimulus intensity, ranging from +13 ± 9 cpm to +276 ± 67 cpm for 40- and 90-dB stimuli, respectively. Inhibition of the amygdala significantly suppressed respiratory rate responses to the high-intensity stimuli (70–90 dB). Submitting rats to the restraint stress significantly elevated the mean respiratory rate (+72 ± 8 cpm) and the dominant respiratory rate (+51 ± 12 cpm), as well as the fraction of high-frequency respiratory rate (+10 ± 3%). Inhibition of the amygdala by muscimol significantly suppressed these responses. We conclude that the amygdala is one of the key structures that are essential for expression of respiratory responses to stressful or alerting stimuli in rats.

Full textAbstract:
Freely moving rats exhibit complex motor and cardiovascular responses to tactile stimulation (12.5 psi air puff, 100-ms duration). In naive Wistar-Kyoto rats, the behavioral response is characterized by a short-latency (25 +/- 1 ms) jumping event, the magnitude of which habituates to repeated stimuli. In a paradigm of consecutive tactile stimuli, each delivered at 30-s intervals, the arterial pressure (AP) response is consistent in profile (36.4 +/- 1.7 mmHg, initial stimulus) and habituates rapidly (15.4 +/- 2.2 mmHg, at 20th stimulus). Rates of habituation of the jumping behavior and AP increase are similar and significantly correlated (P less than 0.01), suggesting partial common mediation. Heart rate changes are bimodal and highly dependent on stimulus number. Initial stimuli elicit bradycardia (-42 +/- 7 beats/min), habituating to extinction by stimulus 10. A temporally delayed tachycardia becomes evident by trial 5 (19 +/- 5 beats/min) and persists unchanged throughout the remainder of the 30-stimulus session. Delayed tachycardia may represent activation of secondary autonomic mechanisms. The nature of cardiovascular responses elicited by the tactile stimulus suggests a somatomotor reflex mediated through the ventrolateral medulla. Adrenal enucleation exaggerated the magnitude of transient bradycardia and abolished extinction of bradycardia with repeated stimuli. Adrenal medullary secretion has only minor importance in direct mediation of the response, but this study suggests that adrenal function plays an important role in tonically setting the level of cardiac responsiveness to parasympathetic vs. sympathetic stimulation.(ABSTRACT TRUNCATED AT 250 WORDS)

Full textAbstract:
Decisions in almost all domains of life receive support from automation in the form of alerts, binary cues, recommendations, etc. People often use automation or decision aids without having experience with the system, because the system may be new or because they rarely use it. When such experience is unavailable, people will base their use of the system on information they may have received about it and on descriptions, often given as probabilities or proportions. Examples are the sensitivity and specificity of a diagnostic procedure in medicine or the True Positive and False Positive rates of a detector. People use these descriptions to decide to what extent they can rely on the information. So far, it is unclear which aspects of the information about a system determine people’s evaluation of the system from a description. These evaluations will determine the trust they put in the indications from the system and the adjustment of system properties, such as thresholds. To gain some insights into this issue, we conducted an experiment. We developed descriptions of 12 systems in a quality control setting, in which participants had to detect faulty items in a production process. We used Signal Detection Theory (Green & Swets, 1966) to determine the system properties. The systems differed in d’ (1.5 or 2.5), the threshold setting lnβ (-1, 0 or 1) and the prior probability for a signal pS (.05 or .2). Half of the participants saw diagnostic values, receiving descriptions in terms of the probabilities of Hit and False Alarms, while the other half saw descriptions as predictive values, receiving the Positive Predictive Value (PPV) and the Negative Predictive Value (NPV) of each system. In the past, we have shown that people adjust system thresholds better when they see predictive values (Botzer, Meyer, Bak, & Parmet, 2010). Fifty-six students evaluated the systems in a classroom setting on a scale between 0 (completely useless) and 10 (perfect). In addition to the d’ and lnβ, which we specified when we designed the systems, we also computed for each system the Probability of Correct Indication (pCorrect), the Expected Value (given the costs and benefits in the description), and the transmitted information according to Information Theory. We analyzed the results with multivariate analyses of variance and by computing the correlations between the evaluations and system properties. The results showed that participants’ responses were mainly correlated with d’. The effects of the threshold setting lnβ and of pS were small, compared to the effects of d’. The correlations with the Expected Value and the transmitted information were smaller and could be explained through d’. Thus, people evaluated a system in terms of its ability to differentiate between signal and noise. They did not evaluate the system according to the economic value it provided or the transmitted information. In addition, participants evaluated systems with different thresholds (lnβ) similarly. This means that in our experiment participants did not differentiate between more and less appropriate threshold settings. The ability to identify better or worse settings is important, because these settings are often the main system parameter users can adjust. These findings, in addition to the inherent problems that already exist in user adjustments of systems (Meyer & Sheridan, 2017), make it unlikely that people can adjust system settings correctly.

Full textAbstract:
ABSTRACT The ShakeAlert earthquake early warning system aims to alert people who experience modified Mercalli intensity (MMI) IV+ shaking during an earthquake using source estimates (magnitude and location) to estimate median-expected peak ground motions with distance, then using these ground motions to determine median-expected MMI and thus the extent of MMI IV shaking. Because median ground motions are used, even if magnitude and location are correct, there will be people outside the alert region who experience MMI IV shaking but do not receive an alert (missed alerts). We use 91,000 “Did You Feel It?” survey responses to the July 2019 Mw 6.4 and Mw 7.1 Ridgecrest, California, earthquakes to determine which ground-motion to intensity conversion equation (GMICE) best fits median MMI with distance. We then explore how incorporating uncertainty from the ground-motion prediction equation and the GMICE in the alert distance calculation can produce more accurate MMI IV alert regions for a desired alerting strategy (e.g., aiming to alert 95% of people who experience MMI IV+ shaking), assuming accurate source characterization. Without incorporating ground-motion uncertainties, we find MMI IV alert regions using median-expected ground motions alert fewer than 20% of the population that experiences MMI IV+ shaking. In contrast, we find >94% of the people who experience MMI IV+ shaking can be included in the MMI IV alert region when two standard deviations of ground-motion uncertainty are included in the alert distance computation. The optimal alerting strategy depends on the false alert tolerance of the community due to the trade-off between minimizing missed and false alerts. This is especially the case for situations like the Mw 6.4 earthquake when alerting 95% of the 5 million people who experience MMI IV+ also results in alerting 14 million people who experience shaking below this level and do not need to take protective action.

Full textAbstract:
Opioid users are an at-risk community. Risk of opioid overdose among substance users has increased tremendously in the last decade. Many factors, including adulterated drugs and hesitation in calling emergency response services, have led to many individuals not receiving the required harm reduction treatment, during an overdose incident. The problem is further compounded by the fact that many users are using alone in private residences and hence, no support mechanisms are available for them to assist them in case of an overdose situation. To circumvent this scenario, citizen training in Naloxone, an overdose harm reduction drug, has been promoted. However, there lies an essential communication gap between the citizens who have the training and the Naloxone kit and an active overdose event. Many at-risk communities may face the same challenge, especially if they are at risk of social isolation and voluntary/involuntary self-harm.
Through our work, we wish to mobilize change in such at-risk communities, by studying the backend infrastructure of a crowdsourced emergency response system, called as a Peer Alerting Lifeline. The system would be responsible, for connecting peer responders, to an actual emergency event. Specifically, in the case of substance overdose, this would allow Naloxone kit holders to be informed of an overdose event in their vicinity and respond to the same. We aim to study the design infrastructure of such a system.Graduate

Full textAbstract:
The Acute Care of at-Risk Newborns (ACoRN) program trains health care providers to stabilize that most challenging and enigmatic of medical patients: the unwell newborn. Early assessment, intervention, and management of at-risk or unstable infants can be critical for their survival and long-term health. Clinical care standards and educational programs to address these requirements are needed. The ACoRN program provides a unique, prioritized, and systematic approach to newborn stabilization for health care professionals with any degree of experience. ACoRN-trained providers learn to gather information, prioritize, intervene appropriately, and deliver high quality care to at-risk and unwell newborns in any setting. Because research and practice have advanced dramatically in recent years, the need for a new ACoRN text, the program’s centrepiece, became essential—hence the development of this new edition, which reflects current guidelines and evidence-based best practices. ACoRN teaches the concepts and skills required to stabilize unwell newborns through system-based algorithms (Sequences), each with its own chapter: respiratory, cardiovascular, neurology, surgical conditions, fluid and glucose, jaundice, thermoregulation, and infection. The ACoRN mnemonic defines stabilization steps and chapter structure: alerting signs, core steps, organization of care, response, next steps, and specific diagnosis and management. Each chapter includes educational objectives, key concepts, learning points, and at least one case scenario with questions and answers to reinforce content and learnings. This book is written for any health professional who may be required to participate in the stabilization of sick or preterm babies within their scope of practice.

Full textAbstract:
While hyperinsulinemia is a common contributing mechanism in the pathogenesis of polycystic ovarian syndrome (PCOS), other mechanisms may give rise to or add to the effects of hyperinsulinemia, as well as other causes of hyperandrogenism, in the pathogenesis of PCOS. Such underappreciated causes may include autoimmune, insulin receptor mutations, mutations of post-receptor insulin signaling response elements, polymorphisms of LH, androgen, and estrogen signaling pathways, epigenetic alterations in hormonal signaling cascade response elements, infestations and infections with organisms capable of endocrine disruption by various mechanisms, as well as drugs and other chemicals which may be endocrine disruptors. In addition, alterations in the gut, oral, or vaginal biome may be associated with PCOS and insulin resistance and may, in some instances, have a role to play in its pathogenesis. In this chapter I plan to review what is known about these lesser-known causes of PCOS, in the hopes of alerting clinicians to consider them and stimulating investigators to better understand PCOS pathogenesis in general and, hopefully, develop more individualized, precision treatment and prevention strategies for the people in our care.

The ACoRN process chapter shows how ACoRN works, step by step. ACoRN’s goal is to identify and manage the unwell or at-risk newborn at, or very soon after, birth or resuscitation. Nine key steps in the ACoRN process are explained, assessing the requirement for resuscitation, followed by 8 systems-based chapters and Sequences (a system-based algorithm for care): respiratory, cardiovascular, neurology, surgical conditions, fluid and glucose, jaundice, thermoregulation, and infection. The ACoRN mnemonic determines the structure of the chapter: alerting signs, core steps, organization of care, response, next steps, and specific diagnosis and management. Essential components, such as the ACoRN Primary Survey, the Sequence, the prioritized Problem List, and the Level of Risk, are described. Diagrams and examples illustrate this process, and the first case scenario shows when and why stabilization should be initiated.

Full textAbstract:
The infection chapter captures all the clinical indicators of possible neonatal infection that appear as Alerting Signs (marked with an asterisk [*]) in almost every ACoRN Sequence. Infection signs require appropriate response and follow-up, but these and associated risk factors for infection are now evaluated as ‘higher risk’ (red flags) or ‘lower risk’ (non-red flags) in the Infection Assessment Table. Care and treatment of suspected infections, including early antibiotics while awaiting cultures, are determined by the presence and number of red flags and non-red flags. The presence of two or more non-red flags heightens risk for sepsis in the newborn, an often subtle condition which impacts stabilization across multiple systems. Diagnostic tests to determine infection site and causative organism are described and evaluated. Close observation and frequent reassessment of infant status using the ACoRN Primary Survey and Sequences are recommended. Two case scenarios compare respiratory distress risk for infection.

Context: Parkinsonism is a clinical syndrome characterized by bradykinesia, tremor at rest, muscle stiffness and postural instability. Parkinson’s disease is the most common cause of parkinsonism. Pathogenic mutations in the leucine- rich repeat kinase 2 gene (LRRK2) have been identified in PARK8-linked autosomal dominant parkinsonism. This mutation is the most common and explains about 1–7% of family cases of parkinsonism of European and American origin and 1–3% of sporadic PD.

Full textAbstract:
Abstract Oil & Gas offshore platforms are industrial "towns", ranked among the most hazardous working environments. Emergency situations in such environments are unpredictable and characterized by time pressure and rapidly changing conditions. OffshoreMuster brings together the latest technological advancements in real-time personnel tracking and e-mustering, complementing the existing Health and Safety (HSE) procedures, by enabling situation awareness over personnel location and status which is a key factor supporting better decision-making towards zero casualty in emergency situations. The system's underlying technology, developed after years of dedicated research and development efforts, consists of specialised low-power wireless wearable devices, customised gateways and a secure backbone network infrastructure feeding a modular decision support software system with real-time streams of data for processing and visualisation of information relevant to personnel situation assessment. HSE processes have been transformed into systematic procedures, allowing additional computer-aided decision support features, like the real-time observation of the fire-fighting team response status, the concentration of people in specific areas, instant alerting or the last-known position of a missing person. Lightweight ubiquitous devices in the form of a bracelet or embedded in the uniform are assigned to People on Board (PoB) and periodically transmit real-time location and status awareness data. A network of dedicated gateways, which are placed at specific locations on the platform or vessel, connected through the infrastructure's ethernet or wireless network, relay the data to a central decision support system. Specialised localisation algorithms and data analytics tools process the data to estimate the personnel positions and PoB status information, interactively visualising in real-time location awareness, incident escalation and alerting, which can significantly reduce response time and speed up a safe evacuation procedure. Computer-aided decision support combined with ultra-low power autonomous IoT technologies systems play a significant role in controlling, managing, and preventing critical incidents in harsh working environments, contributing into minimisation of accidents occurrence in Oil & Gas environments. The presented underling technology has been validated in maritime environments with more than 500 people taking part in real drills (TRL-8). The technology has been tailored to enhance the safety of personnel working in offshore Oil & Gas assets, currently being under laboratory testing and evaluation while a full-scale industrial deployment is scheduled for the autumn of 2021. The OffshoreMuster hardware and software components, integrated into a unified solution tailored for the offshore Oil & Gas industry, are presented for the first time. The system has been designed and developed with the support of the European Commission, co-funded by the Fast Track to Innovation Program (Grant Agreement Number 878950).

The George A. Smathers Libraries at the University of Florida (UF) are participating in an innovative program to explore whether making electronic theses and dissertations (ETDs) available in print through online retail sites can have positive impacts for graduates, the University, and the general public. Digitization and metadata enhancement have improved discoverability and ease of access for ETDs in the Institutional Repository at the University of Florida (IR@UF). However, through this new program, research can be shared widely beyond academe with practitioners, corporate researchers, independent scholars, and international readers. This paper will describe how the Smathers Libraries have worked with a corporate partner, BiblioLabs, to leverage online retailers’ discovery engines to promote print versions of ETDs while alerting readers to the free digital versions available in the IR@UF. This paper will also share how alumni, current graduate students, and other campus stakeholders have responded to the pilot of this new service. The Libraries are monitoring referred traffic to the IR and sales data. UF is the first university to contribute content to this effort, but we expect others to follow suit if the data supports the expectations of the University, the Libraries, and our graduates.

In InSITE 2022: Informing Science + IT Education Conferences. Informing Science Institute, 2022. http://dx.doi.org/10.28945/4991.
Full textAbstract:
Aim/Purpose: The purpose of the present study was to examine the relationship between a converged wireless-sensor/cellular network architecture and cybersecurity, in terms of transmission delay, to deliver remote grassfire alerts to firefighters in Southeast (SE) Colorado. Background: Agriculture, rural communities, a thriving cattle industry, and a kaleidoscope of flora and fauna characterize the plains of SE Colorado. Unfortunately, the hot and dry climate of SE Colorado combines with the ever-expanding wildland-urban interface (WUI), presenting an enormous grassland fire risk. A review of the literature revealed a deficit of research that addressed the alerting mechanism between remote WSN-based fire detection and response forces. Methodology: The present research pursued a converged-network solution from two courses of action (COA) to address the wildfire risk. COA-A and COA-B coupled the ZigBee-Pro and ZigBee-IP WSN protocols, respectively, with the 4G-LTE infrastructure prevalent throughout SE Colorado to bolster alert information availability. Following construction of the simulation models, the Ostinato packet generator performed 194 end-to-end transmissions with each COA to ascertain the better-performing solution in terms of network transmission delay. Contribution: The study’s findings offer a starting point for subsequent research that will lead to a proposal for SE Coloradans – and beyond – to help bridge the gap between detective WSNs and the response forces that can subdue remote grassfires. To the extent the authors could surmise, the current research effort was the first to model and simulate a one-way, UDP-based wireless network that comprised a WSN node, two WSN-Cellular gateway designs, and several 4G-LTE infrastructure components. The simulated environment also measured and compared the end-to-end network transmission delay for two unique solutions, including the convergence process within the WSN-Cellular gateway. Findings: COA-B proved the superior solution with a 16.2% delay improvement over COA-A. An independent-samples t-test confirmed the statistical significance between the results’ means. Recommendations for Practitioners: COA-B offered a remote SE Colorado grassfire alerting solution that minimized network transmission delay and maximized alert payload to responding firefighters. However, the generalizability of the current research’s results indicates utility for firefighters providing overwatch to grasslands throughout the world – wherever valuable grasslands intersect with a 4G-LTE on-ramp. Within the United States and outside SE Colorado, 4G-LTE from multiple carriers exists throughout the Great Plains. U.S. industries, communities, and ecosystems that rely on the abundance of Great Plains grasslands abound and feature use cases ripe for benefit from the present research. Recommendations for Researchers: Additional studies could offer more depth and recommend solutions to bolsters the alert mechanism between fire detection and response capabilities. The literature is teeming with research that improves the efficacy of fire-detective WSNs. However, the dearth of practice-oriented research that delivers an alert to firefighters in SE Colorado and elsewhere warrants further work on top of the present study. Impact on Society: The study’s findings need not apply only to grassfires. Much research and residual challenges exist on the topic of forest and wildfire alerts throughout the world. Although the generation mechanisms may differ, propelling an alert over available infrastructure – 4G-LTE or other – offers a workable solution to ensure timely response to unsolicited fires. Future Research: The current research’s incremental construction of delay measurements for COA-A and COA-B encourages the creation of an end-to-end model in network simulators such as NS3 or OMNeT++. A network simulation framework like OMNeT++ would allow a more comprehensive representation of wireless channel effects on overall delay. The creation and testing of a physical COA-B prototype would provide a proof of concept for the current study. Future work could bridge the gap between any varietal of remote sensor network and the audience that consumes sensor data anywhere in the world.

"'The Application of Human Factors in Wake Vortex Encounter Flight Simulations for the Reduction of Flight Upset Risk and Startle Response."

Full textAbstract:
The current top safety risk concern for commercial air travel in Europe is known as “Flight Upset”. This term, also known as “Loss of Control in Flight”, entails the flight crew suddenly finding themselves in an unexpected, complex, and even confusing situation that if not resolved quickly can lead to a major accident. Accidents such as AF447 and the two B737 Max accidents fall into this category. An undesirable aspect of such events is known as the “startle response”, wherein one or both flight crew, finding themselves in dire and dangerous conditions, may experience ‘startle’, which temporarily affects their cognitive functioning. This may only last half a minute, but its effect can have a severe impact on the survivability of such events. A Horizon 2020 research project called SAFEMODE, which aims to integrate Human Factors techniques into a unified framework for designers in aviation and maritime domains, is exploring the use of state-of-the-art flight simulation facilities to measure pilot performance in severe wake turbulence events, which can induce the startle effect. This is part of a broader use case within SAFEMODE to validate the design of a new Wake Vortex Air Traffic Alert for the Cruise phase of flight. A tactical short-term alert to the Flight Crew, ahead of the wake encounter, is seen as beneficial to reduce the startle effect and support the appropriate management of these conflicts. The envisaged risk-alerting logic relies on a ground-based predictor, connected to the Air Traffic Control system, displaying an alert to the En-route Air Traffic Controllers, who can then provide a cautionary advisory to the Flight Crew so they can take appropriate actions.The cockpit flight simulations involve type-rated flight crews in realistic and representative cruise flight conditions, using a Type VI Boeing 737-800 full flight motion-based simulator (also used for Upset Prevention and Recovery training programs). During the simulation runs, pilots are exposed to simulated wake vortex encounters, corresponding to a strong wake-induced upset (between 30 and 40 degrees of bank), with or without prior ATC wake caution, and varying the initial direction of roll between left and right to limit the simulation training effect.Human Factors measurements include workload, situation awareness, trust, acceptability-based user feedback, as well as psychophysiological measures such as eye-tracking and Electro-Dermal Activity (EDA). In particular, eye-tracking is expected to support the refined determination of the sequence of actions before and after detection, and the reaction of flight crews to the en-route ATC Wake alert.A cockpit flight simulation, via combining the analyses of psychophysiological measures, flight parameters, expert observations and subjective pilot feedback, enables evaluation of Flight Crews performance in preparing for, managing or avoiding wake encounter upsets with the new ATC wake alerts, showing the net safety benefits. Early results indicate that the simulations can indeed induce startle effect, and that repeated exposure enables flight crew to overcome it and manage the situation in a more measured and controlled fashion.

Full textAbstract:
Abstract In the recent past, there has been cases of carbon dioxide leak related incidents and casualties. Carbon dioxide has been recognized as a significant worthy hazard in the industrial environment for about 100 years. low concentrations of carbon dioxide are not harmful, but on a high concentration can affect the respiratory function and the central nervous system. This prompted the development of this carbon dioxide gas leakage detection system as a safety measure to reduce this risk. This carbon dioxide gas leakage detection is developed with an Arduino microcontroller and an MQ-135 sensor for a highly accurate and fast response system. The detection system incorporates an LCD Screen for displaying the status and level of concentration of the gas leakage, a buzzer as an alarm to give audio alerts, indicating and alerting users on the gas leakage, a number of LED lights to indicate the gas leakage status. The system also incorporates a GSM Module which sends SMS alerts and make calls to users during the gas leakage regardless distance. The Arduino microcontroller is programmed using embedded C++ language and all the peripherals connected to it through its pins. When the detector is in normal state, the LED light is lit on Green to show a normal range in concentration of gases and/or absence of a gas leakage. When there is gas leakage, the system transitions into a harmful state. The system displays the status of the gas leakage on the LCD Screen just as other LED lights light up in conjunction with an alarm buzz giving an audiovisual alarm to the monitoring mobile device. Also, the GSM Module sends out SMS alerts and calls to designated users regardless of their distance from the gas leak vicinity to notify them of the gas leak in order to take immediate action to control the gas leakage situation. The gas leakage detection is not only highly accurate but cheap and portable and can be used for industrial and domestic safety.

Full textAbstract:
When Hurricane Harvey hit the Texas coast as a category 4 hurricane on August 25, 2017, it resulted in $125 billion in damage, rivaling only Hurricane Katrina in the amount of damage caused. It also resulted in the deaths of 88 people and destroyed or damaged 135,000 homes. Much of that devastation was the result of flooding. The storm dumped over 27 trillion gallons of rain over Texas in a matter of days. Some parts of Houston received over 50 inches of rainfall. The potential liability that dam and reservoir operators may face for decisions they make during storm and flooding events has now become a major concern for Texas citizens and its elected officials. Law suits have now been instituted against the federal government for its operation of two flood control reservoirs, as well as against the San Jacinto River Authority for its operation of a water supply reservoir. Moreover, the issues and concerns have been placed on the agenda of a number of committees preparing for the 2019 Texas legislative session. This report reviews current dam and reservoir operations in Texas and examines the potential liability that such operators may face for actions and decisions taken in response to storm and flooding events. In Section III, the report reviews dam gate operations and differentiates between water supply reservoirs and flood control reservoirs. It also considers pre-release options and explains why such actions are disfavored and not recommended. In Section IV, the report evaluates liabilities and defenses applicable to dam and reservoir operators. It explains how governmental immunity can limit the exposure of state and federally-run facilities to claims seeking monetary damages. It also discusses how such entities could be subject to claims of inverse condemnation, which generally are not subject to governmental immunity, under Texas law as well as under the Fifth Amendment to the U.S. Constitution. In addition, the Section discusses negligence and nuisance claims and concludes that plaintiffs asserting either or both of these claims will have difficulty presenting successful arguments for flooding-related damage and harm against operators who act reasonably in the face of storm-related precipitation. Finally, Section V offers recommendations that dam and reservoir operators might pursue in order to engage and educate the public and thereby reduce the potential for disputes and litigation. Specifically, the report highlights the need for expanded community outreach efforts to engage with municipalities, private land owners, and the business community in flood-prone neighborhoods both below and above a dam. It also recommends implementation of proactive flood notification procedures as a way of reaching and alerting as many people as possible of potential and imminent flooding events. Finally, the report proposes implementation of a dispute prevention and minimization mechanism and offers recommendations for the design and execution of such a program.
