ABSTRACT

The prudent teaching of the forensic fire engineering analysis of complex building fires must include the subject of computer fire modeling, particularly the use of the Fire Dynamics Simulator (FDS), developed by the National Institute of Standards and Technology (NIST).  However, the problems associated with FDS require that large buildings be divided into rooms or zones, with each assigned to an individual computational mesh.  These mutli-mesh models often produce relatively long execution times of days or weeks and typically require parallel processing computing clusters, which require technically challenging set up and maintenance.  These performance gains can only be accomplished using high performance parallel processing computer clusters designed specifically to use operating systems and hardware that exploit the parallel functions of the FDS code.  This paper presents best practices from the latest research in constructing small, medium, and large-scale high performance parallel processing computing clusters for use in academic environments to support NIST’s FDS fire model.

Hypothesis vs. Theory

http://www.diffen.com/difference/Hypothesis_vs_Theory September 15, 2017

A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable.

Purpose: To present an uncertain possibility that can be explored further through experiments and observations. To explain why a large set of observations are consistently made.

From Out of the Abyss...

This week’s article from the past is titled Incendiary Fires Can Be Spotted and was written by Benjamin Horton, CPCU, who was President of the National Adjuster Traing School in Louisville, Kentucky..  It is taken from the Decembe 1968 Vol. XVI No.5 issue.

Incendiary Fires Can Be Spotted 

In the new issue of NFPA Journal®, President Jim Shannon said the Association will focus on the leading causes of home fires, including cooking. "We also need to continue to push hard for home fire sprinklers. That's still a large priority for NFPA, and we plan to work very aggressively in 2014 on our residential sprinkler initiative," he said.

NFPA 921, Guide for Fire and Explosion Investigations plays a fundamental role in fire and explosion investigations. A new edition of NFPA 921 is scheduled to be published in 2014. For years, this document has played a critical role in the training, education and job performance of fire and explosion investigators. It also serves as one of the primary references used by the National Fire Academy to support its fire/arson-related training and education programs. It is imperative that investigators understand the scope, purpose and application of this document, especially since it will be used to judge the quality and thoroughness of their investigations.

SAN DIEGO - A Team 10 and Scripps News investigation found arson fires are not investigated properly in many American cities -- including San Diego -- due to a chaotic patchwork of reporting systems and standards.

Many deliberately set building fires are not reported to the federal government.

Nationally, just 5 percent of all residential building fires are intentionally set, according to the National Fire Incident Reporting System, which is part of the Department of Homeland Security.  Data collected by Scripps News suggests the national arson rate to be significantly higher.

Advanced Explosive Recognition 2013

The Central Valley Arson Investigators association continued the tradition of providing outstanding training at their annual Advanced Explosive Recognition class.  The training was held once again at the Tulare International Agri-Center grounds.  This year’s topic was the history of the American criminal bombings.  Guest speaker Ed Nordskog, LA Sheriff’s Department, lead the class through the history of American bombings, from the earliest bombings in America right up to the most current-day events.

Practical Approaches for Recouping Good Faith Payments

Larry-Arnold-article

by: Larry Arnold

Faced with growing losses, insurance companies are focusing on fraud management and implementing risk mitigation controls, while at the same time remaining cognizant of their duty of good faith to policyholders.  So what happens when an insurer makes good faith payments on legitimate elements of an insurance claim but subsequently uncovers fraud in other elements of the claim?  Is the insurer entitled to recover all monies paid as part of the claim?  Or only the amount paid in reliance on the insured's misrepresentations?

Previously, there was no clear answer.  It was safe to assume that an insurer could recover monies paid on a claim under the right circumstances – the difficulty occurred when trying to recover payments made prior to the established fraud date.  For example, in California, the insurance code states, “If a representation is false in a material point, whether affirmative or promissory, the injured party is entitled to rescind the contract from the time the representation becomes false.”

Recent trial court rulings in favor of insurance companies, however, are changing the claims landscape.  These rulings will impact the way insurance companies handle genuine claims that are subsequently tainted by fraud, encouraging them to be proactive in recouping good faith payments.

Water and Burning Cooking Oil

The three pictures below show the effect of putting one cup of water in a pan of one cup of oil on fire. You should always choose to cover the burning pan with a lid or cookie sheet and then turn off the burner. If you put water on the oil fire, the effects will almost always be deadly.

Surviving fires: How common mistakes can lead to devastating fires

Shared by Jamie Novak, St Paul Fire Department

Surviving_firesCOON RAPIDS, Minn. - Fire does not schedule home visits, nor do firefighters arrive by appointment.

In the interest of fire safety, we decided to change that.

During two days of shooting, a crew of firefighters and KARE 11 photographers with a dozen cameras gathered at the most deadly place for fires in Minnesota: home.

Jamie Novak, a St. Paul Fire investigator, helped us locate a three-bedroom rambler in Coon Rapids that was already scheduled for demolition.
