▼ Receiving false and nuisance alarms is a well known
problem in industrial alarm systems. The main cause of this problem
is poor alarm design which is the result of huge number of
configured alarms and lack of automatic and analytical design
methods. This study targets deriving analytical methods for
designing alarm parameters such as alarm limits, alarm deadbands
and delay timers. The relation between false and missed alarm rates
along with chattering is investigated with alarm limits and
deadbands. There are two equations presented to estimate the
optimal alarm limit with respect to deadbands and statistical
characteristics of the process data. Since reduction of alarm
chattering is a primary goal in redesigning the alarm parameters,
the analytical relation between chattering with alarm parameters
and process data is also investigated. The alarm chattering index
is derived as a mathematical function of alarm limits, deadbands,
time delays and statistical characteristics of the process
data.

▼ A incontinência urinária, é um problema de saúde com múltiplas repercussões, que interferem negativamente na qualidade de vida dos doentes. Aliado a este facto, está a dificuldade em realizar diagnósticos corretos acerca do grau de incontinência. Sem um diagnóstico correto o tratamento, que já por si é complicado, incorre em dificuldades adicionais. Assim, tem-se assistido ao desenvolvimento de vários produtos para incontinência, cujo objetivo é melhorar a qualidade de vida dos pacientes, face aos danos causados pela doença. Tratam-se de sistemas concebidos para aumentar a autoestima das pessoas na sua presença em público, face ao receio de algum evento de incontinência. Nesse sentido, o principal objetivo deste trabalho, é a criação de um sistema de alarme para incontinentes, que é constituído por uma componente de deteção de líquido, incorporada em roupa interior específica para incontinentes e uma componente de geração de alarme, que corresponde a um dispositivo android . A comunicação entre os dois dispositivos é estabelecida, através do protocolo Bluetooth. A componente de deteção de líquido, inclui a implementação de um sensor de líquido baseado em materiais fibrosos, integrado no substrato têxtil específico para incontinentes. É também responsável por, processar a informação proveniente do sensor e por comunicar com o dispositivo android . Os resultados provenientes do sensor consistem na resistência elétrica produzida, relacionada com a quantidade de líquido libertado. Por sua vez, a componente de geração de alarme, é uma aplicação móvel, concretizada com o propósito de emitir alarmes, quando recebe sinais provenientes do dispositivo. Além disso, fornece uma interface de configuração do dispositivo de deteção, para o nível de alarme desejado. Permite ainda registar eventos de incontinência numa base de dados local. O trabalho desenvolvido tornou possível a conceção e implementação de um sistema de alarme para incontinentes, sendo que o nível de alarme pode ser configurado em função da quantidade de líquidos. A existência duma base de dados com registo de eventos permite a monitorização em modo offline por períodos mais longos.

▼ As plantas industriais são compostas por processos que somam milhares de variáveis.
Visando garantir segurança e qualidade à operação, esses processos são monitorados e
alarmes são configurados de modo a indicar algum possível mau funcionamento. Dentre
os problemas mais comuns associados aos alarmes industriais podemos citar: alta ocorrência de falsos alarmes, alarmes perdidos e alarmes ruidosos, sobrecarga dos operadores
e enxurrada de alarmes. Estes problemas estão relacionados com o processo de seleção
das variáveis monitoradas, as técnicas de ativação e desativação de alarmes, entre outras
características do processo e do sistema de alarme. Este trabalho tem como foco definir
uma abordagem para configurar alarmes eficientes e significativos para o operador. A
abordagem aqui proposta tem inspiração no fluxo de trabalho de um cientista de dados
que inicialmente precisa identificar as características das bases de dados utilizadas para
então aplicar transformações que tornem os dados mais adequados possibilitando a extração de informações valiosas. Muitas vezes o cientista está interessado em criar um
modelo que descreve os dados ou possibilita predições. Esta é uma tarefa muito similar a
de configuração de alarmes onde é necessário selecionar as variáveis relevantes e definir
as configurações de cada alarme de maneira a classificar o funcionamento do processo
como adequado ou não e auxiliar a identificar a falha. A abordagem proposta aqui é
constituída de quatro partes: descrição dos dados, seleção de variáveis, sintonia e avaliação de desempenho. Durante a etapa de descrição são obtidas informações relevantes
sobre os dados como presença de eventos, quantidade de eventos distintos, duração de
eventos, etc. Na etapa de seleção são definidas as variáveis relevantes para detecção de
anormalidades. A sintonia dos alarmes é similar a um processo de treinamento, onde um
modelo é construído para descrever o comportamento dos dados. Finalmente durante a
avaliação, as configurações encontradas são aplicadas a um histórico do processo para
aferir se as configurações se comportam de maneira a atender restrições de segurança e
qualidade. Como estudo de caso, uma configuração de alarmes industriais foi obtida para
o Tennessee Eastman Process que é um simulador amplamente usado pela comunidade
acadêmica.

Advanced Alarm Monitoring Based on Alarm Data.

▼ Alarm systems are critical assets of modern industrial
plants to assist operators in managing plant upsets and hazardous
situations. A good alarm system must detect abnormalities and warn
the operators promptly and yet at the same time not mislead,
overload or distract the operators. However, in many actual cases,
alarm systems often function poorly, and distract and overload
operators due to nuisance alarms and alarm floods. Consequently,
operators might be confounded by these problems, and be less alert
to true alarms. To ensure process safety and improve efficiency of
alarm systems, this thesis focuses on the development of advanced
alarm management techniques, specifically using alarm data. Four
problems have been solved. First, a new method is developed to
detect and quantify correlated alarms in the presence of occurrence
delays, which are identified as the main causes leading to
erroneous conclusions from existing methods. The effectiveness of
the method is ensured by a statistical test based on the
distribution of occurrence delays and a signal conversion mechanism
of generating continuous-valued pseudo alarm sequences. Second, in
order to assist prediction of alarm floods and prevention of their
negative consequences, an accelerated local alignment method is
proposed to find similar alarm flood sequences, which are very
likely caused by the same root cause. To improve the computational
efficiency and accuracy, three novel strategies are incorporated,
including the priority-based similarity scoring strategy, the
set-based pre-matching mechanism, and the modified
seeding-extending steps. Third, to identify abnormality propagation
paths and detect root causes, a causality inference method based on
binary-valued alarm data is developed as an alternative in the
absence of process data. A modified transfer entropy (TE) and a
direct transfer entropy (DTE) are formulated based on the two
characteristics of alarm signals, namely, the random occurrence
delays and the mutual independence of alarm occurrences. Lastly, a
data-driven technique is proposed to discover association rules of
mode-dependent alarms from historical Alarm & Event
(A&E) logs. The proposed method can help process engineers
in discovering consequential nuisance alarms, and configuring
state-based alarming strategies. The effectiveness and
applicability of the proposed methods are validated by case studies
using real industrial alarm data. Using the proposed methods,
interesting patterns can be extracted from the alarm data, and used
to improve alarm monitoring by reducing nuisance alarms, addressing
alarm floods, and tracking the propagation of
abnormalities.

▼ In the process industry, the alarm system acts as a
layer of protection between the Basic Process Control System (BPCS)
and the Safety Instrumented System (SIS). The BPCS is designed for
automatic regulation of day to day process operation and SIS comes
into picture when emergency shutdown is required. There are
specific standards worldwide that define how BPCS and SIS system
are to be designed and expected to work. However, not many well
defined standards are available for design and management of
industrial alarm systemsmainly due to the heavy involvement of
human factors. Alarm management has gained complexity mainly due to
increasing size of process plants and also due to the Distributed
Control System (DCS) that presents little motivation for limiting
the number of variables on which alarms can be configured. Alarm
management lifecycle for maintaining an efficient alarm system as
suggested by the International Society of Automation standards (ISA
SP18.02) is discussed in this work with emphasis on monitoring and
assessment and design stages. In this work, novel tools for
assessment of alarm system based on routinely collected alarm event
data are proposed and demonstrated. The primary focus of these
tools is to identify nuisance alarms such as chattering and
redundant alarms. Alarm event data is represented mathematically
and indices are proposed to calculate the extent of similarity
between two alarms and also to estimate the extent of chattering in
an alarm. Two of the most commonly used techniques for reducing
alarm chatter, delay timers and latches are discussed in detail.
Effect of varying the size of on-delay, off-delay timers and
latches on the accuracy of detection is discussed in the Receiver
Operating Characteristic (ROC) framework from a theoretical view
point by modeling them using Markov chains. Use of Return to Normal
(RTN) information in addition to alarm events information in
designing delay timers is also discussed. Finally, advantages of
multivariate techniques such as Principal Components Analysis (PCA)
based T2 and Q statistic as opposed to univariate monitoring are
discussed in the same framework using simulation examples and an
industrial case study.

▼ Today’s intensive care units monitor patients through the use of various medical devices, which generate a high ratio of false positive alarms due to a low alarm specificity. The false alarms have resulted in a stressful working environment for healthcare professionals that are getting more desensitized to triggered alarms and causing alarm fatigue. The patient safety is also compromised by having high noise levels in the patient room, which disturbs their sleep. This thesis has developed an intelligent alarm system with an improved alarm management and the use of 23 intelligent algorithms to minimize the number of false positive alarms. The suggested system is capable of improving the alarm situation and increasing the patient safety in critical care. The algorithms were modeled with fuzzy logics consisting of delays and multi parameter validation. The results were iteratively developed by having focus groups with various experts.

▼ All information systems are prone to failures, whether they’re human, infrastructural or applicational, therefore requiring constant monitoring in order to prevent service unavailability affecting business.
Sputnik is a platform for graphical and intuitive representation of infrastructural and applicational monitoring, allowing to represent circuits, tables, graphs or for example checking the availability of a server or the accumulation of records in a table. This platform allows real-time problem detection/visualization and supports it’s resolution/escalation
in a efficient way.
The Checklist is a centralized platform where knowledge and information are organized/ structured in CI’s (Configuration Items) and relationships between them. Intended as a framework for searching any type of relevant information, including relationships between the existing CIs.
Asterisk Gateway is a pilot platform (proof-of-concept), designed to trigger automatic
phone calls replacing the need for human action, thus speeding the process of scaling. In the context of this PEI, calls are triggered when a CI falis, alerting the respective support team.
In this PEI I intended not only, to improve/develop alarmistic platforms over the PTSI systems but also to improve my technical knowledge, management and effective input on the process of monitoring and alarms, minimizing human action and helping them when necessary.

▼ The large quantity of alarms characteristic of clinical settings have resulted in nursing staff suffering from a phenomenon termed ‘
alarm fatigue’.
Alarm fatigue is desensitization via habituation – as these commonly heard noises cause caregivers to have delayed or no response to alarms.
Alarm management was ranked number one on the annual top ten list of technology hazards afflicting healthcare institutions published by the ECRI Institute for 2012. Several patient safety organizations have established
alarm fatigue as a priority concern, and are working to eradicate the issue from the healthcare environment by 2017. To better understand the problem, a simplified simulation model was created using AutoMod
® to investigate the routine processes involved in responding to cardiac arrhythmia alarms on a telemetry unit as well as the sources of noise attributing to
alarm fatigue. By quantifying these workflows and response strategies, this model can be utilized to aid administrators and managers in selecting
alarm escalation times as well as modifying hospital protocols to minimize
alarm response time and enhance nursing efficacy. The results also support the identification of hospital policy elements where clinical workflow could be augmented based on the physical layout of the telemetry floor, use of distributed
alarm notification systems and staff roles and responsibilities.

▼ Modern hospitals are plagued by excessive alarms generated by patient monitoring technologies with very high sensitivity and low selectivity leading to high rates of false and clinically irrelevant alarms. Multiple studies have shown that these false and clinically irrelevant
alarm rates can negatively impact patient care and lead to "
alarm fatigue".
Alarm hazards have been named the number one health technology hazard by ECRI Institute for 2012 and 2013. A review by the FDA revealed 566
alarm related deaths in a recent four year period.
At a large, teaching hospital in Massachusetts, a quantitative, database driven approach to
alarm management was adopted in the acute care and medical/surgical environment with the intent to identify and implement technological, clinical, educational, and workflow practice changes to curtail excessive alarming. A database representing a subset of the total
alarm burden from patient monitoring devices was analyzed. The measured subset revealed a combined total of 31.5 arrhythmia and pulse oximetry alarms per patient per day. Observations determined the database contained 35%-55% of the total
alarm burden.
Two countermeasures were successfully deployed, two were deployed with inconclusive results and four were developed and not deployed. The result of this ongoing effort was a reduction in the number and duration of clinically irrelevant, non-actionable alarms generated and a gradual shift in the culture surrounding monitoring alarms. The work conducted will serve as a roadmap for future process improvement work with patient monitoring systems.

▼ Pipelines transport millions of barrels of petroleum products every day. Oil and gas pipelines have become important assets of the economic development of almost any country. Government regulations or internal policies regulate the safety of the assets for the population and environment where these pipelines run. Various strategies and technologies have been introduced for monitoring pipelines, but the most common technology to protect pipelines from occasional hazardous incidents is Computational Pipeline Monitoring (CPM). This technique collects and gathers information from the field related to pressures, flows, and temperatures to estimate the hydraulic behavior of the product being transported. Using the gathered information CPM systems compare its values with standard values and provides a notification if any anomaly or unexpected situation occurs. The result is an alarm to an operator in a supervisory control room. According to Hollifield, it is becoming an increasing problem that there is no standard for plant operators yet, whereas improved design can lead to better performance (Hollifield et. al., 2007). So, the objective of this experiment was to explore the effect of different alarm interfaces on controller response at different alarm rates. A simulated liquid pipeline system was developed and a between subject experimental design was performed to evaluate three different types of alarm window interfaces (Categorical, Chronological, and Revised Categorical), two alarm rates (10 in 10 minutes and 20 in 10 minutes), and three levels of alarms (high, medium, and low). Thirty one participants participated in this research, and the performance of participants was measured in terms of acknowledgement time, response time and the accuracy of response. Results showed that the participants’ performance in terms of response time, acknowledgement time, and accuracy of response was significantly different between chronological, categorical, and revised categorical displays. Data analysis showed that the means were shorter in revised categorical display in terms of response time, acknowledgement time, and accuracy of response. This study will be useful in developing new standards for alarm display.

▼ The dispersal behaviour of apterous pea aphids, Acyrthosipon pi sum (Harris) was studied in the laboratory and field. In the laboratory, aphids exhibited two types of behaviour while on the ground, after dropping from plants in response to predators. Most aphids showed a high frequency of turning and tended to return to the plant they left, while a smaller proportion walked in straight lines and did not return to the plant they left. Adults and older nymphs had the highest proportion of individuals which showed the second type of behaviour and adults showed the greatest tendency to disperse to plants more distant than the nearest available plants. Young instar aphids were less successful at locating a host than older nymphs and adults.
Aphids were placed on the central bean seedlings within plots, inside large field cages. Adult coccinellids were released into two of the cages while the other cage remained predator-free. Aphids in the cages with predators frequently moved between plants, while aphids in the predator-free cage did not. Adult aphids colonized more plants and had a lower mortality while on the ground than all other instars. Aphids did not show a preferred dispersal direction and the distance dispersed by aphid nymphs was proportional to the density of aphids on the plant they left. The importance of emigrating apterae in the exploitation of new resources and the regulation of aphid populations is discussed.
Bean plants infected with an aphid transmitted virus were transplanted into the central position of bean plots in the field cages.
Aphids were placed on the central infected plants and adult coccinellids were released into two of the three cages for three days. Aphids frequently moved to other plants from the centre infected plant in the two cages with predators but not in the predator-free cage. When plants were examined two weeks later, significantly more plants were infected with virus in the cages with predators than in the predator-free cage. New virus infections were correlated with plants that were visited or colonized by aphids from the central infected plant. The influence of predators in the spread of aphid transmitted diseases is discussed.
In laboratory experiments, pea aphids from Vancouver were presented with alarm pheromone from irritated conspecifics. Adult and fourth instar aphids responded to the pheromone by either dropping, running or backing up. Instars one, two and three responded to the pheromone only when a vibratory stimulus accompanied it. A high proportion of all instars responded to the double stimulus by dropping. When adult aphids from Vancouver and Kamloops were presented with alarm pheromone, the Kamloops adults exhibited a more conservative reaction to alarm pheromone. Kamloops adults also were more conservative about leaving their plant when confronted by a coccinellid predator.
A hypothesis is presented, which accounts for the differences in escape reactions between instars and biotypes. The hypothesis takes into consideration predation risk, escape behaviour…

▼ Alarm floods are a crucial problem in the process
industry. An alarm flood makes it difficult for an operator to
react and take necessary actions, which often can lead to risking
an emergency shutdown or a major upset. In many cases, alarm floods
are caused by interrelated process variables, which can be
identified via similar patterns in alarm annunciations. This
similarity can be investigated through alarm pattern analysis of
industrial alarm flood data. In this work, alarm floods are
discussed based on the standards presented in the new ISA 18.2
guidelines and the discussion given in EEMUA 191. A new analysis
method is proposed to identify alarm floods that are similar from
the historical alarm data and group them on the basis of patterns
of alarm occurrences. Patterns in alarm sequences can be
investigated through different distance measures. To calculate a
distance between alarm patterns in two different sequences,
preprocessing of industrial alarm data and effective flood period
isolation are required. Hence, definitions of alarm floods and
alarm flood periods are given based on the new ISA 18.2 standards.
The effect of chattering alarms on alarm floods is also discussed.
Three different distance scores, suitable for capturing alarm
patterns in alarm flood sequences, are introduced. Finally, a case
study on real industrial alarm data is presented to demonstrate the
utility of the proposed analysis.

▼ Fishes in the Superorder Ostariophysi have specialized epidermal club cells that contain an
alarm substance. Damage to these cells causes the release of the
alarm substance which can serve as a useful indicator of predation risk for nearby conspecifics. The majority of research involving
alarm substances has investigated the roles that cues play in anti-predator contexts including learned predator avoidance. In this study I tested the effects of non-predatory stressors including pathogens, pathogen conditioned water, social dynamics, and skin-burrowing parasites on epidermal variables including
alarm cell investment. In experiment 1, fathead minnows, Pimephales promelas, were exposed to different levels of the pathogenic water-mold, Saprolgenia ferax to determine the effect it would have on the epidermis. Minnows exposed to Saprolgenia had significantly more
alarm cells than those exposed to the control solutions. The treatments had no effect on body condition,
alarm cell size, mucous cell density, mucous cell size, or epidermal thickness. In experiment 2, social dynamics were manipulated by pairing minnows with either a familiar partner or an unfamiliar individual and exposing them to Saprolgenia ferax. The treatments had no effect on body condition,
alarm cell density,
alarm cell size, mucous cell density, mucous cell size, or epidermal thickness. In experiment 3, minnows were exposed to either Saprolgenia or Saprolgenia conditioned water to determine whether the physical presence of zoospores was required to induce a change in epidermal properties. The treatments had no effect on body condition,
alarm cell density,
alarm cell size, mucous cell density, mucous cell size, or epidermal thickness; suggesting that water conditioned by Saprolgenia may be sufficient to induce a change in
alarm cell investment. In experiment 4, minnows were exposed to three different infection rates of skin burrowing parasites (trematode cercariae) to determine its effect on the epidermis. Minnows exposed to high levels of tramatode cercariae had significantly more
alarm cells than those exposed to either low levels or those in the control treatment. The treatments had no effect on body condition,
alarm cell size, mucous cell density, mucous cell size, or epidermal thickness. In experiment 5 and 6, cultures of Saprolegnia ferax were exposed to skin extracts from various fishes. S. ferax cultures exposed to fathead minnow skin extracts, which contain
alarm cells showed the least amount of growth, while cultures exposed to swordtail skin extracts, which lack
alarm cells, showed an intermediate amount of growth. Cultures exposed to fathead minnow skin extracts showed the least amount of growth compared to cultures exposed to either the synthetic
alarm cue or the control. The results of these experiments suggest that disease does appear to influence
alarm cell investment and there appears to be some property found in fathead minnow skin that inhibits S. ferax growth.

▼ Alarm fatigue, the progressive desensitization of clinical staff to audible alarms in their environment, has been re-established as a National Patient Safety Goal by The Joint Commission as of January 1, 2014. In order to manage the number of alarms experienced by hospital employees, facilities are charged with finding a way to monitor their existing
alarm load and then develop methods and policies by which to reduce or mitigate the threat of
alarm fatigue. This study used an archive of 9.76 million patient monitoring alarms collected over an eight-month period in order to develop a process by which patient monitoring alarms could be analyzed with high specificity across multiple units of differing specialties and acuity levels.
Trends in the distributions of patient monitoring
alarm data were identified, with the greatest potential contributors to
alarm fatigue being confirmed as the medium and low priority alarms, comprising greater than 70% of all patient monitoring alarms observed, and condition-based distributions showed strong correlation to average distributions across patient care units of differing specialties and acuity levels. These distributions demonstrated the expected exponential decay in frequency of alarms as the condition shifted farther away from the physiologically acceptable range, with one exception. A trend of spikes in high heart rate alarms at heart rate values that were multiples of 10 was observed, and at multiples of five for low heart rate alarms, suggesting that heart rate limits should be considered differently than those for other vital signs. The time of day in which alarms initiated was also analyzed, showing a direct relation between periods of time where patients are interacted with by clinical and/or support staff, with a physiological sensitivity to these interactions increasing as the acuity level of the unit increased.

▼ Background and Objective: In most hospitals, alarms
from physiologic monitors are frequent, and the vast majority of
alarms are not actionable. Concerns about
alarm fatigue prompted
The Joint Commission to urge hospitals to take immediate action to
improve
alarm management in 2013. Understanding the types of alarms
that occur most frequently will guide hospitals striving to reduce
alarm frequencies. The objective of this study was to evaluate the
burden of
alarm frequency and to describe the patterns of
physiologic monitor alarms at a single, free-standing children’s
hospital including the rates of alarms and the most common causes
of alarms.Methods: This was a cross-sectional study of physiologic
monitor alarms at a freestanding children’s hospital. Data were
collected from all inpatient units over 7 consecutive days in
August 2014 for each physiologic monitor
alarm using a central
alarm collection system. Alarms were classified by
alarm cause
(e.g. low blood oxygen level), and sensor (e.g. pulse oximetry
probe). Procedural, radiology, rehabilitation, and psychiatry units
were excluded. Each unit census was determined by four daily
measurements during the study period from the electronic health
record.Results: There were a total of 220813 alarms over the study.
The most common cause of alarms during the week was technical
alarms, or alarms generated for issues with the monitoring
equipment (e.g. probe off or low battery), followed by clinical
alarms for low blood oxygen level and high heart rate. Pulse
oximetry probes were the most common sensor to cause alarms.
Alarm
rates varied significantly by unit and by cause.Conclusion:
Alarm
rates at a children’s hospital were quite high. Technical alarms, a
type of
alarm unrelated to a change in patient physiologic status,
were the most common cause of
alarm. Strategies targeted at
reducing technical alarms from physiologic monitors may help reduce
overall
alarm frequencies.

▼ In this thesis, two Graphical User Interfaces (GUIs)
are designed in MATLAB to perform causality analysis and alarm
management. Finding out the root-cause of a fault scenario or an
abnormality in a large industrial process typically requires one to
logically analyze cause and effect relationships between variables.
Causality analysis can play a vital role to capture process
connectivity and topology and to identify relationships among the
variables in a process. The availability of large volumes of
industrial process data has now opened the way to develop
data-driven methods for causality detection. In the first tool,
different techniques of data visualization along with three
data-driven methods of causality analysis, namely,
cross-correlation, transfer entropy, and Granger causality, have
been implemented. Case studies are provided to illustrate the
capture of process connectivity using both transfer entropy and
Granger causality methods. Recent studies have shown that the
number of alarms in process industries is far more than the
approved standards because of a very high number of false and
nuisance alarms. The large number of alarms distracts the operator
from safe and regulatory monitoring of the processes, which leads
to plantwide upset and affects overall productivity of the system.
Therefore root cause identification of faults and alarm management
have become very important for process industries. The second tool
for alarm management is proposed where historic alarm data can be
used to find out the top bad actors in the system. Also functions
for correlated alarms and similarity between different alarm flood
analysis have been implemented in the GUI for easier root cause
identification.

▼ To meet the demands of safety, quality and efficiency,
process monitoring is of great importance. However, a serious
problem exists in the industry: too many alarms are raised for
operators to handle. Consequently, techniques need to be developed
in order to reduce nuisance and false alarms to an acceptable
level. Motivated by this, my thesis focuses on alarm systems
improvement, specifically the development of data-driven techniques
for the analysis and design of alarm systems. Developed methods are
based on either process data or alarm data, the two types of data
mainly used in alarm systems. Three problems are considered. First,
a univariate alarm signal filtering technique is discussed. The
design of an optimal alarm filter for the best alarm accuracy,
namely, minimizing a weighted sum of false and missed alarm rates
(probabilities), is presented. Moreover, a sufficient condition for
moving average filters being optimal linear alarm filters is also
provided. Second, alarm flood pattern analysis based on
multivariate alarm data is addressed. A modified Smith-Waterman
algorithm considering time stamp information is proposed for alarm
flood pattern matching. Third, the application of a new
multivariate statistical analysis technique, the principal
component pursuit (PCP) method, to process monitoring is thoroughly
discussed. An optimal scaling method is proposed as the
preprocessing step. A coordinate descent algorithm is provided to
search for the optimal scaling vector, whose global convergence is
proved. After multivariate process modeling, a PCP-based fault
detection and diagnosis approach is introduced. An industrial
project on a major extraction process in Alberta to improve its
alarm system is described. Based on the historical data, a
predicted reduction on the alarm rate by applying a variety of
alarm system rationalization techniques is estimated. A significant
improvement on the alarm system is expected.

▼ As animal behaviour theory has developed over the past 70 years, much attention has gone toward social information use. Social cues in a variety of forms can be critically important in finding food and mates, in defending territories, and in avoiding predators. A wide variety of prey species are capable of learning from social information regarding predation threats, but little attention has gone toward factors that influence the acquisition of such information, how it compares to other learning mechanisms, or how prey learn socially about the absence of risk. Herein, I present research with fathead minnows, Pimephales promelas, where I first showed that learned fear responses were similar between social learning and individual learning, but socially-acquired information was more persuasive and had an overriding effect on previously learned safety. Using repeated exposures to general predation cues that lacked specific information about the predator’s identity, I induced uncertainty in naïve individuals (observers) or in knowledgeable individuals (models) within a social pairing. Repeated exposure to risk, regardless of uncertainty, promoted a high-risk phenotype that was characterized by propensity to freeze, stereotypic route-tracing, and neophobia – a phenomenon where animals show generalized fear responses toward novel stimuli. Attempting to weaken this phenotype, I paired high-risk individuals with models that were experienced with an odour as safe, but a single conditioning with one ‘safety model’ had little effect. Instead, interacting with high-risk individuals caused models to indirectly acquire the high-risk phenotype. Hence, this social transfer of information caused models to behave fearfully, making them poor demonstrators of safety. To counteract this, I used groups of calm models, or multiple, individual calm models in succession. Both strategies weakened fear in observers, as well as socially-transferred fear in models, but surprisingly this effect was much stronger among individuals exposed to risk in isolation, despite their tendency for stronger neophobia initially. While our basic knowledge of social systems has grown substantially in recent years, rarely has it been applied to human issues. My work bridges animal behaviour theory and human psychology, arguing that our understanding of predation-related fear and the information transfer in social animals can prove fruitful in understanding post-traumatic stress and behavioural therapy for its recovery.

▼ A novel model was developed to test the use of short data sets for testing various
alarm thresholds as part of an energy management program. Several years of 15-minute interval data were utilized from five buildings in Jacksonville, Florida. The model aggregated the data by day type and occupancy so that there were four period types used. For all of the buildings’ meters, their daily usage by period type was tested against the threshold to determine if an
alarm would be triggered, which would then be assigned a reward and cost based upon the type and duration of response. The risk management value was converted to dollars, in order to normalize the energy and time. It was determined that the 5-month short data set was the most appropriate choice for short data sets. In addition, it was concluded that the thresholds should be set between 0.8 and 1.0 standard deviation above the average of the short window. Several recommendations for further study are also enclosed.

▼ Background: Critical care nurses are exposed to an excessive number of clinical alarms in the patient care environment. Prior studies show that the vast majority of arrhythmia alarms are false and can lead to alarm fatigue. Patients with both true and false arrhythmia alarms present a unique challenge, because exposure to false alarms can desensitize nurses to true alarms and may lead to missed true events. Objectives: The purpose of this study was to examine patients with both true and false arrhythmia alarms and determine: (1) frequency of patients with true and false arrhythmia alarms in a sample of 461 intensive care unit (ICU) patients, (2) patient, clinical, and electrocardiographic characteristics associated with both true and false alarms, and (3) the number and types of true and false arrhythmia alarms (e.g., asystole, ventricular fibrillation, ventricular tachycardia, accelerated ventricular rhythm, pause, and ventricular bradycardia). Methods: This was a secondary analysis utilizing data from the UCSF Alarm Study. Results: In 461 ICU patients, 71 (15%) patients had a total of 10,699 true and false arrhythmias alarms: 1,348 (13%) were true and 9,351 (87%) were false. Compared to patients without true and false alarms, the presence of ventricular pacemaker, bundle branch block, altered mental status, mechanical ventilation, left ventricular assist device, and cardiac ICU admission were associated with the presence of true and false alarms (p = 0.001). Patients with both true and false alarms had longer length of ICU stay than patients without both true and false alarms (208 hours versus 75 hours; p = 0.001). Accelerated ventricular rhythm was the most common alarm (37%), followed by ventricular tachycardia (31%). Conclusion: We found that 15% of ICU patients have both true and false alarms and the vast majority are false. Further research is needed to build and test improved ECG arrhythmia algorithms that adjust for clinical and ECG characteristics associated with false alarms. Nurses’ awareness of these characteristics may help them identify patients at risk for excessive alarms and aid in developing unit specific solutions to decrease alarm fatigue.

▼ Examensarbetet bygger på en egen observation av brister som finns i de trygghetslarm som kommunerna använder sig av idag. Idén är att personer ska känna sig trygga på allmänna platser. Arbetet kommer att baseras på tre grundparametrar, position, fall och puls. Det är både teoretiskt fakta men även att testa olika system. Första fasen i arbetet är att strukturera ner grundparametrarna i mindre delar. Arbetet utförs genom att avläsa marknadens sortiment på trygghetslarm. Därefter utföra en egenskapad testanalys på komponenterna. Den andra fasen är att testköra och sammanfoga grundparametrarna till en produkt och att avläsa både marknaden och prisbilden. Även hur armbandet ser ut i dag och att tillverka en konstruktion som passar bättre dagens behov. Tredje fasen är en analys på vad som blev bra och vad som blev mindre bra, för att kontrollera att samtliga kriterier uppfyllts. En kontroll så att samtliga kriterier som har angetts uppfyllts. Produktens slutliga konstruktion för detta projekt ska ha en instruktionsmanual och en tillverkningsmanual. Konstruktion av ett nytt trygghetslarm genomfördes. Ett antal komponenter och analyser utfördes för att välja rätt komponenter till rätt grundparameter. Grundparametrarnas mål uppfylldes, ett av dem var trygghet på allmänplats.

▼ An
alarm is a warning of an approaching situation which requires a response. This study considered the influences of alarms in the clinical health environment. The Emergency Care Research Institute considered
alarm hazard as the number one health technology hazard for the years 2012 through 2014. The Joint Commission set a standard for all hospitals in the US to assess
alarm fatigue in their monitoring process and to develop a systematic, coordinated approach to clinical
alarm system management. In order to comply with this requirement, a working definition of
alarm fatigue is necessary. To the very best of our knowledge, there have been no studies proposing a quantitative definition of
alarm fatigue, a way to measure it, or exploring the influence of
alarm fatigue on performance deterioration. This observational study undertook the objective of defining
alarm fatigue and its role on performance deterioration in a quantitative way. A survey using a questionnaire proposed by the American College of Clinical Engineering Healthcare Technology Foundation was conducted before the observations to assess the attitude of nurses toward the existing
alarm monitoring system at the hospital where the research took place. An extensive literature review and Hierarchical Task Analyses were conducted in order to reveal all the possible influencing factors behind
alarm fatigue. From these,
alarm fatigue was defined and measured in terms of mental workload and three types of affect: boredom, apathy, and distrust. A conceptual model was developed considering the significance of working conditions and staff individuality on
alarm fatigue and, consequently,
alarm fatigue on staff performance. Staff performance was measured in terms of response (yes/no), response time and number of ignored alarms. Several analytical approaches were performed to find association between
alarm fatigue and staff performance. The results show that, in general, performance deterioration is actually influenced by a combination of
alarm fatigue with working conditions and staff individuality. In the case of nurses and response time,
alarm fatigue plays no role, only working conditions and staff individuality. These findings suggest that the role of
alarm fatigue as a health hazard in the clinical environment should be reevaluated.

▼ Pipelines transport millions of barrels of petroleum products every day. These systems have significant safety concerns. The BP oil spill in the Gulf of Mexico, while concerned with oil and gas extraction rather than distribution, shares many of the same safety and reliability issues as distribution systems, and demonstrates the significant potential for major disasters in the pipeline industry. In this work, a research study is being conducted to further understanding of the role of operators in the management of alarm systems and to measure the performance of operators in handling abnormal situations like pressure loss, liquid inflow/outflow variation and alarm floods. In an Abnormal Situation Management (ASM) consortium traditional interface study, improving the human machine interaction (HMI) in designing the operator’s user interface resulted in 41% less time for the operators to deal with events like leaks, power failures, equipment malfunction and equipment failures in an unstable plant (Errington, 2005). To evaluate the impact of different alarm rates and interfaces on operator performance, a liquid pipeline simulation experiment of 1 hour was developed and the operators ran the experiment repeatedly at different alarm levels: chronological and categorical displays with the alarm rate of 15 alarms per 10 minutes (chronological display only), 20, 25 and 30 alarms per 10 minutes (the last rate with the categorical display only). Twenty five pipeline and refinery operators participated in this research, and the performance of operators was measured in terms of acknowledgement time, response time and the accuracy of response. Results showed that the operator’s performance in terms of response time was significantly different between 25 and 30 alarm rates. Experiments to compare the response times in both the alarm windows did not show significant difference statistically, but the means were better in categorical display. This study will be useful in developing new standards on operator performance.

▼ Objective assessment for the effect of hearing protectors, background noise levels, and backup
alarm acoustic features on listeners' abilities to localize backup
alarm signals in the horizontal dimension, as well as on their ability to detect backup
alarm signals in the distance dimension, is lacking in the acoustics and safety literature. Accordingly, two research experiments were conducted for this dissertation.
In the first experiment, the effect of seven hearing protectors, two background pink noise levels (60 dBA and 90 dBA), and two backup
alarm signals (standard and spectrally-modified) on the ability of normal hearing listeners to localize backup
alarm signals in the horizontal dimension was investigated. Results indicated that a diotic sound transmission earmuff significantly degraded localization accuracy as compared to all other hearing protectors and the open ear condition. In addition, no significant difference existed between the open ear condition and the other hearing protectors in localization accuracy in most of the conditions tested. However, the E-A-R/3M HiFiTM earplug was advantageous in localization performance since it provided a significantly higher percentage correct localization than the Moldex foam earplug, the diotic earmuff, and the dichotic earmuff in 90 dBA pink noise. As for main effects of the other independent variables, the 90 dBA pink noise significantly degraded localization performance as compared to the quiet condition of 60 dBA, and a spectrally-modified backup
alarm significantly improved localization performance as compared to the standard (narrowband) backup
alarm. Potential application of these results includes the revision of backup
alarm standards. In addition, these results provide clear advice for safety professionals to avoid the application of diotic sound transmission earmuffs for workers if localizing backup alarms is important.
In the first experiment, listeners' feeling of comfort for each hearing protector was assessed subjectively by using a comfort rating scale. In addition, a subjective assessment for listeners' confidence in their localization decisions was established. Results indicated no significant difference between the hearing protectors in terms of comfort. However, in terms of listeners' confidence in localization decisions, their confidence was significantly degraded when they were fitted with the diotic earmuff. By contrast, they showed significantly more confidence in their localization decisions when they were fitted with the E-A-R/3M HiFi™ earplug as compared to when they were fitted with the Moldex foam earplug, the E-A-R/3M Ultrafit™ earplug, and the Bilsom passive earmuff.
In the second experiment, listeners' performance in detecting a stationary backup
alarm signal, including both a standard (narrowband) and broadband (pulsed white noise)
alarm, was determined while they were equipped with various passive and electronic hearing protection devices. Listeners' performance was quantified by detection distance, which was defined as the…

▼ In process plants, alarms are configured to notify
operators of any abnormalities or faults. However, in practice a
majority of raised alarms are false or nuisance and create problems
for operators as they face an increasing number of alarms to
handle. In the past, many catastrophic incidents happened only
because of poor performance of alarm systems. Therefore, a
dependable and efficient alarm system is needed to ensure plant
safety and uninterrupted operation. To assess performance of a
plant's alarm system, it is necessary to evaluate various
performances indices. Motivated by this, this thesis develops
quantitative relationships among commonly used alarm attributes and
performance indices. Alarm design techniques, like, deadbands and
delay-timers can significantly reduce false and nuisance alarms.
However, these techniques introduce some delay in raising the alarm
(detection delay). In this thesis, detection delays are calculated
using Markov processes for deadbands and delay-timers. A design
procedure is then proposed that compromises between detection
delay, false alarm rate (Type I error) and missed alarm rate (Type
II error) for an optimal configuration. Inclusion of these indices
in alarm design makes the system more reliable and effective in
nature. Filtering is another widely used alarm design technique in
industries. Two most commonly used filter types in industry are the
moving average filter and the exponentially weighted moving average
filter. However, the effect of filter parameters on the alarm
detection delay is not well known. We investigated this
relationship for the moving average filter and proposed a method to
design filter order. We proposed a generalized delay-timer
framework where instead of consecutive n samples in the
conventional case, n_1 out of n consecutive samples (n_1 <=
n) are considered to raise an alarm. For the generalized
delay-timer, three important performance indices, namely, the false
alarm rate (FAR), the missed alarm rate (MAR) and the detection
delay (EDD) are calculated using Markov processes. Also the
performance and sensitivity of generalized delay-timers are
compared with conventional delay-timers. All theoretical
development and alarm design technique proposed in this thesis are
validated through simulations and several case studies are
conducted to illustrate industrial applications.

▼ In many high-risk domains, such as aviation, driving, and space operations, safety depends greatly on the timely detection and correct identification of alarms. However, due to high levels of system complexity and coupling in those environments, a large number of alarms is sometimes triggered within a short period of time, a so-called
alarm flood.
Alarm floods pose a challenge for operators at various stages of information processing, including detection, identification and response selection. The detection of alarms during an
alarm flood can be difficult due to masking effects. Masking occurs when one signal is obscured by the presence of another simultaneous or asynchronous stimulus. To date, various forms of simultaneous and asynchronous masking, such as change blindness and attentional blink, have been studied almost exclusively for only two stimuli and in single-task conditions. The effects of masking in the presence of a large number of signals and in multi-task environments are not well understood.
Therefore, the goals of this dissertation were to (1) establish the relative contributions of simultaneous and asynchronous masking to missed and misdiagnosed visual and auditory alarms during routine operations and in an
alarm flood, (2) identify the stimulus onset asynchronies (SOAs) at which masking effects are observed in demanding multitask environments, (3) investigate the impact of the number and temporal distribution of alarms on
alarm detection and identification and (4) develop and test countermeasures to overcome observed performance breakdowns. To this end, a series of four experiments were conducted using a simulation of a drone-based package delivery service.
Both simultaneous and asynchronous masking were observed, intramodally and crossmodally, for visual and auditory alarms. The SOA at which asynchronous masking was observed was longer (around 800ms) than reported in basic studies of the phenomenon. The effects of both simultaneous and asynchronous masking were stronger with an increase in the number of alarms; this increase was more pronounced for simultaneous masking. Simultaneous masking also had a stronger effect on auditory alarms, compared to visual alarms. In clusters of 4 or 6 sequential alarms, the first and last alarms were more likely to be detected and correctly identified. During
alarm floods, a speed-accuracy tradeoff was observed, i.e., the response time to alarms was shorter but the identification accuracy was lower, compared to routine operations. Finally, when the criticality of alarms was mapped to preattentive features of the
alarm signal (color and pitch), the masking effects were alleviated, especially for clusters of 4 or 6 concurrent visual alarms.
The findings from this dissertation contribute to a better understanding of the effects of two types of masking on the detection and identification of large numbers of critical signals in high workload multi-task environments. They help inform the development and expansion of models and theories of human perception and cognition…

▼ Desenvolvida em 1987 na Motorola, a metodologia Seis Sigma busca, mediante redução na variabilidade dos processos-chave, obter características críticas para a qualidade (CTQs) com probabilidades de defeitos próximas de zero. Tem-se um processo Seis Sigma quando a distância entre o valor-alvo (VN) da CTQ e o limite de especificação mais próximo for igual ou superior a seis desvios-padrão (σ). Na prática, por maior que seja a atenção dispensada ao processo, a média da distribuição de probabilidades da CTQ pode deslocar em até 1,5σ do valor-alvo, que ainda assim o processo será considerado Seis Sigma. Então existe um intervalo de 4,5 a 6σ, no qual o processo pode variar sem que perca o nível de qualidade considerado de classe mundial. Desta forma, neste trabalho, buscou-se estabelecer recomendações para o planejamento de gráficos de controle de Shewhart ̅ e R para o monitoramento de processos Seis Sigma. Para tanto, estabeleceu-se um desempenho de referência no qual se admitiu a probabilidade do alarme falso conjunto igual ou inferior a 0,01; e a probabilidade do alarme verdadeiro conjunto crescendo de acordo com a redução do nível Sigma do processo, passando de 0 em processos 6σ para 0,10 naqueles 5σ, atingindo 0,90 em processos 4,5σ até atingir a unidade para processos 3σ e inferiores. Nesse sentido, investigou-se planejamentos com combinações entre n = 2, 3, 4 e 5 e k = 2,5, 2,6, 2,7, 2,8, 2,9 e 3,0. Identificou-se que o par de gráficos em questão apresentou bom desempenho quando o processo esteve sob efeito somente do deslocamento da média e perdeu desempenho à medida que ocorreu o aumento da variação como única perturbação ou quando as duas anomalias estiveram atuando. Foi possível identificar que o deslocamento da média é o problema mais observado, a ocorrência simultânea das duas anomalias é menos frequente e a presença exclusiva do aumento da variação é rara. Logo, recomendou-se o planejamento com n = 5 e k = 2,9, para o monitoramento de processos Seis Sigma Práticos (isto é, com nível sigma entre 4,5 e 6σ), que apresentou bom desempenho apenas quando o processo esteve principalmente sob efeito do deslocamento da média. Portanto, é provável que o nível de qualidade dos processos caia sem que os gráficos de controle em questão sinalizem a perda da qualidade em função do aumento da variação, com ou sem a presença do deslocamento da média.
Developed at Motorola in 1987 the Six Sigma methodology seeks, by reducing the variability of key-processes, obtain critical to quality characteristics (CTQs) with defect probabilities close to zero. It has a Six Sigma process when the distance between the CTQs target value (VN) and its nearest specification limit, is equal or greater than six standards-deviations (σ). In practice, despite the big attention being paid to the process, the average of the CTQs probabilities distribution is able to shift until 1,5σ from the target value which even so, the process will be considered Six Sigma. So there is an interval between…
