The Apopka Voice will publish them starting today and running until Friday, December 30th. During the New Year’s weekend (Friday, December 30th – Sunday, January 1st) we will publish a poll and let the readers decide on which story is the most impactful of the year. Originally Published: June 15th, 2016The Apopka City Council voted 5-0 last night to approve Chuck Carnesale as Apopka’s new fire chief. He takes over a department of more than 80 firefighters.“He started as an Explorer at age 13, graduated high school, Fire Academy and EMT school simultaneously in 1989, and was a dispatcher at age 17,” said Mayor Joe Kilsheimer. ” he has filled almost every position at The Apopka Fire department.”“I hate to mention I’ve been on this journey for 33 years when my mother dropped me off to look at fire trucks,” said Carnesale. “Thank you. I won’t let you down. I won’t let the public down. I won’t let the firefighters down.”Carnesale has served as assistant fire chief since 2013, heading up the fire department’s emergency medical and ambulance services. He is certified as a firefighter, EMT/paramedic, fire officer, fire inspector and instructor in various fields. In 1990, Carnesale was hired as a full-time firefighter/EMT. In 2000 he was recognized by then Gov. Jeb Bush as Apopka’s Firefighter of the Year.Chuck CarnesaleHe was promoted to engineer in 2001, lieutenant in 2005, captain and EMS coordinator in 2006 and assistant fire chief in 2013. Carnesale attended Seminole State and Valencia colleges, Florida State Fire College and the National Fire Academy in Emmitsburg, MD.He has served on several medical boards, and this year Orange County Medical Director Dr. George Ralls appointed him to the Orange County EMS Advisory Council.The City Council was pleased with Kilsheimer’s choice.“Chuck is an amazing person,” said Commissioner Kyle Becker. I know he is going to do a fantastic job. I couldn’t be more happy for you (Carnesale).”“I’m glad we brought someone in from our own fire department,” said Commissioner Billie Dean. “We have the best fire department in America. We should hire from within. I commend you (Kilsheimer) on the choice.”Carnesale replaces former Fire Chief Lee Bronson.

Brain can navigate based solely on smells This has many applications in VR. Our recent work at the University of Bath has applied this method to solving a problem with how people estimate distances when using virtual reality headsets. A driving simulator for teaching people how to drive could lead to them compressing distances in VR, rendering use of the tech inappropriate in such a learning environment where real world risk factors come into play.Understanding how people integrate information from their senses is crucial to the long-term success of VR, because it isn’t solely visual. Maximum likelihood estimation helps to model how effectively a VR system needs to render its multi-sensory environment. Better knowledge of human perception will lead to even more immersive VR experiences.Put simply, it’s not a matter of separating each signal from the noise; it’s about taking all signals with the noise to give the most likely result for virtual reality to work for practical applications beyond the entertainment world. Virtual reality isn’t confined to the entertainment world. There has also been an uptake of VR in more practical fields – it’s been used to piece together parts of a car engine, or to allow people to “try on” the latest fashion trends from the comfort of their home. But the technology is still struggling to tackle a human perception problem. One theory blends together computer science and psychology. Maximum likelihood estimation explains how we combine the information we receive across all our senses, integrating it together to inform our understanding of the environment. In its simplest form, it states that we combine sensory information in an optimal fashion; each sense contributes an estimate of the environment but it is noisy.Noisy signalsImagine a person with good hearing walking at nighttime in a quiet country lane. They spot a murky shadow in the distance and hear the distinct sound of footsteps approaching them. But that person can’t be sure about what it is they are seeing due to “noise” in the signal (it’s dark). Instead, they rely on hearing, because the quiet surroundings mean that sound in this example is a more reliable signal. This article was originally published on The Conversation.

At the University of Bath we’ve applied VR to exercise; imagine going to the gym to take part in the Tour de France and race against the world’s top cyclists. But the technology doesn’t always gel with human perception – the term used to describe how we take information from the world and build understanding from it. Our perception of reality is what we base our decisions on and mostly determines our sense of presence in an environment. Clearly, the design of an interactive system goes beyond the hardware and software; people must be factored in, too.It’s challenging to tackle the problem of designing VR systems that really transport humans to new worlds with an acceptable sense of presence. As VR experiences are becoming increasingly more complex, it becomes difficult to quantify the contribution each element of the experience makes to someone’s perception inside a VR headset. When watching a 360-degree film in VR, for example, how would we determine if the computer-generated imagery (CGI) contributes more or less to the movie’s enjoyment than the 360-degree audio technology deployed in the experience? We need a method for studying VR in a reductionist manner, removing the clutter before adding each element piece by piece to observe the effects on a person’s sense of presence. This scenario is depicted in the image below, which shows how the estimates from human eyes and ears combine to give an optimal estimate somewhere in the middle. The blue curve shows a compromise of the audiable and visual senses. It is also taller, which means it corresponds to a higher likelihood in its estimate of what can be perceived in the dark.
