Abstract
For the last 15 years, cutting extinguishers and the cutting extinguisher method have been used in thousands and yet thousands of fire interventions by municipal firefighters around the globe.
The numbers of cutting extinguishers installed on ships are few in comparison to the numbers in use by the fire and rescue services. Adding the higher level of safety awareness on-board naval vessels, compared to the general public, naval shipboard fires, and thus experience, tend to be scarce. It’s hard to find real cases.
However, in many areas, special units from municipal fire and rescue services, such as Maritime Intervention Response Groups and similar teams, are assigned to shipboard firefighting when vessels are near or alongside quays. These units are trained to fight fires on board ships and have great routine and experience in fighting fires, on-board as well as on shore.
Cross discipline learning is crucial to reach high efficiency in introducing new technology and methods. This paper will describe and illuminate the experiences, procedures and methods from fighting real fires on-board ships using the cutting extinguisher and its method. It will also conclude in lessons learned from the actual incidents.
Tactical ventilation and cutting extinguishing method in shipboard firefightingAnders Trewe
Methods and Procedures including Positive Pressure Ventilation and Positive Pressure Attack on board Naval Vessels
A discussion on studies and practical results of the Royal Swedish Navy; onboard traditional mild steel naval vessels as well as light weight composite stealth vessels
Abstract
Tactical ventilation, both positive and negative pressure, has been used for at least two decades in civilian firefighting as an optional tool or method to clear out smoke and gain visibility, as well as mitigating hot fire gases to spread through the construction while fighting the fire.
Adding great volumes of air, under pressure, to a fire incident at sea might seem to be a dangerous and volatile venture. Is positive pressure ventilation a feasible method on board a ship, particularly on board a naval vessel? What precautions and preventive measures could or should be taken if applying positive pressure ventilation while shipboard firefighting? What other methods should be considered in combination with positive pressure ventilation in order to leverage the outcome?
Royal Swedish Navy has initiated tests and trials of combining various methods with the ambition to determine a short list of the most efficient and effective methods and method combinations. The Visby Stealth Corvette Class vessels are in addition engineered to provide dynamic ventilation solutions to various fire incident scenarios.
Cutting extinguishers and SOP's onboard naval vesselsAnders Trewe
The document discusses a presentation given at the MAST Asia 2015 conference in Yokohama, Japan about integrating cutting extinguishers with naval firefighting standard operating procedures. The presentation focused on the Swedish Navy's experience using cutting extinguishers on both traditional steel vessels and new lightweight composite stealth vessels. It described how cutting extinguishers were implemented as a new firefighting tool and the opportunities and challenges this presented for naval methods, doctrines, and standard operating procedures. The Swedish Navy found additional value from integrating cutting extinguishers beyond more effective firefighting, including enhanced shipboard firefighting and safer procedures for crews.
Efficient and Safe Shipboard Firefighting – More Cooling with Less WaterAnders Trewe
Mitigation of austerity has recently closed upon the level of importance of mitigation of fire among naval forces. Budget cuts combined with demands to keep the naval fleet’s operational levels intact have created new opportunities of cooperation and thinking outside the box in extending present vessels’ life span. Investing in new technology could not only add lifetime, but enhance the safety of the crew and the ability to stay focused on the mission with less effort.
Fires onboard naval vessels will not only impact the vessel, but threaten to compromise the mission as a whole. Traditionally, shipboard firefighting on steel hull vessels engage a lot of crew members, consumes a lot of water and takes focus off of the mission.
Modern composite light weight material structures require immediate intervention in the fire compartment, less the supporting structure will be damaged. In addition, societal changes impose alignment to civilian work safety regulations.
High pressure water mist has been scientifically proven a very efficient extinguishing agent; cooling and inerting combustible smoke gases with less water than otherwise. It rapidly cools the fire room, mitigates backdrafts and makes the re-entry procedure safer for the BA-crew.
Fixed installed high pressure water mist systems are often limited to designated high risk fire areas due to cost and limitation of auxiliary emergency power. Breach of such systems, or fires caused by external attacks at a non-designated area, would require traditional boundary cooling and/or BA-attack; both crew and water consuming, high risk tasks, thus mission compromising.
A mobile, versatile high pressure water mist system with cutting/penetrating abilities would add the redundancy necessary to handle a breach in the fixed installed systems. It would also add efficient and safe fire protection to compartments not protected by other systems.
The Swedish Navy has invested in cutting extinguishing systems to effectively enhance safety and comply with RMS 2010/NSC; for redundancy on their new Visby Class Composite Stealth Corvettes, as well as retrofitting on steel hull vessels for cost effective and enhanced bulkhead fire protection. Of course, the overall argument is securing the ability to succeed with the mission.
The Cutty Sark ship underwent a major restoration project after being damaged by a fire in 2007. The project faced challenges due to the ship's historic status but implemented an innovative, fully fire-engineered approach. This included raising the ship above the dry berth, developing a fire strategy that considered life safety and heritage protection, and using computational modeling to evaluate fire risks and evacuation. The fire-engineered solutions allowed increased visitor capacity while protecting the Grade I listed ship.

The Dutch DK Group has converted an old cargo vessel to test their Air Cavity System (ACS) technology, which aims to reduce ship fuel consumption by pumping air under the hull to create an air cushion. Extensive sensors will monitor the performance of the ship during sea trials to evaluate if the ACS lives up to promises of 15% fuel savings. Germanischer Lloyd is assisting with certification and measurements to objectively assess the viability and fuel savings potential of the new technology. If successful, ACS could be adopted widely and significantly reduce the industry's environmental impact and costs.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).
AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork
Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.
Organizational culture includes values, norms, systems, symbols, language, assumptions, beliefs, and habits that influence employee behaviors and how people interpret those behaviors. It is important because culture can help or hinder a company's success. Some key aspects of Netflix's culture that help it achieve results include hiring smartly so every position has stars, focusing on attitude over just aptitude, and having a strict policy against peacocks, whiners, and jerks.

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray
1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework.
2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections.
3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.

Figure 16 Vincenzo Florio at Palermo (2009) and Lisco Gloria at Fehmarn Belt (2010)
In essence, this made it possible for the salvor to enter the car deck on the Vincenzo Florio once it was
alongside in Palermo, to fight off the fires in the vehicles using the cobra, and finally save 75% of the
property, at a loss of €20 000 000. The Lisco Gloria was a 100% loss, at €60 000 000. Johan Luijks, one of
the contracted salvors of Yang Ming Green and Vincenzo Florio, later said that if there had been a cobra
onboard the Lisco Gloria, the fire could have been limited to the truck that originally caused the fire.46
This was also one of the driving facts for the German Havariekommando to invest in five marine cobra
units in 2011 for their MIRG’s operating out of five coastal cities in the Baltic Sea and the North Sea.
The Dieppe Seaways incident originated from an oil leakage in a boiler furnace. As the situation evolved,
the fire spread through expansion of hot fire gasses from the furnace into the surrounding compartment.
The situation deteriorated due to preconceived conclusions of the ship’s chief engineer, lack of or
misinterpreted liaisons between the ship master and the command of the FRS. The situation prior to
opening the door was not assessed properly. If the risk of back draft had been on the agenda, one would
probably not been content with the dry power action and one would probably had checked whether the
fixed water mist system had been activated automatically – after all, water mist is the best extinguishing
media to mitigate risk of back draft.47
However, immediately after the backdraft, proper liaisons were set up, thorough risk assessments were
made and evaluations of available actions were done. In the course of this work, it became apparent that
the automatic function of the fixed high pressure firefighting had not gone off. This was engaged
manually, but did not have significant effect based on the monitoring of the exhaust temperature from
the furnace. Eventually, a firefighter suggested that the cobra should be used, which, when finally
engaged, showed significant temperature drop of the exhaust temperature. Again, suggesting and using
the cutting extinguisher at this situation, requires knowledge and understanding of the efficiency of the
