NEW YORK, Jan. 25, 2021 /PRNewswire/ — Kaylee Franklin, a student at Middletown High School in Middletown MD, has been named winner of the fourth annual Drive Safe D.C. PSA Contest, sponsored by The National Road Safety Foundation in conjunction with the Washington, D.C. Auto Show. 

The contest invited teens from D.C., Virginia and Maryland to submit their ideas for a 30-second public service announcement that warns of the dangers of speeding, which is a factor in 26 percent of fatal crashes nationwide, killing an estimated 9,000 people every year.  

Kaylee, 14, will receive $2,000 and an Emmy Award-winning director will work with her virtually to make her idea into a finished TV public service announcement that will air on more than 160 TV stations nationwide.  It will be featured on the nationally-syndicated TV program «Teen Kids News.»   

Kaylee’s public service message opens with two cars talking to each other in a parking lot.  A new car brags to an older car about all its new features.  The older car admits it doesn’t have all the new features.  The new car talks about how fast it can go.  The spot closes showing a tow truck pulling a smashed car, as a mother and child get into the older car.  As the child buckles herself into the car seat, the older car says to the new one, «I may not be a smart car, but I have a smart driver.»  The words «Be a SMART driver, speeding kills» come onto the screen.

«I’ll be driving in about a year, and while I’m not nervous about my own driving, I don’t want to be afraid of others on the road around me,» Kaylee said.  «My message is that you need to be cautious on the road, and that includes not speeding.»

«Kaylee’s message will help make people think about their behavior when they get behind the wheel,» said Michelle Anderson of The National Road Safety Foundation, a non-profit that promotes safe driving.  «It conveys a message that no matter how advanced your car is, you as the driver have to be responsible and speeding can have much more serious consequences than getting a ticket.»

«We salute Kaylee for an idea that we think will resonate with teens and, in fact, drivers of all ages,» said Washington Auto Show President and CEO John O’Donnell.  «It shows that even as today’s cars have many great features to help keep us safe, the ultimate safety feature is a safe driver.»

Ryan Corbin, 18, of Stevensville, MD, was named runner-up and will receive a $1,000 prize.  He is a student at Kent Island H.S.

The National Road Safety Foundation, Inc. (NRSF) is a 501 (c)(3) non-profit organization that for nearly 60 years has been dedicated to reducing crashes, deaths and injuries on our nation’s highways by promoting safe driving habits through greater public awareness.

CAMBRIDGE, Mass., Jan. 25, 2021 /PRNewswire-PRWeb/ — Detecting the presence of an unmanned underwater vehicle (UUV) is usually achieved by intercepting the noise radiated by its propeller. In a noisy harbor, this task is hindered because the acoustic signature of a UUV and the noise in the local environment often present too much signal complexity for current technologies to process.

That may be about to change. Researchers at Draper, Massachusetts Institute of Technology (MIT) and Woods Hole Oceanographic Institute (WHOI) have developed an acoustic remote sensing method for high-precision propeller rotation and speed estimation of unmanned underwater vehicles.

The new method is detailed in a study published in the Journal of the Acoustical Society of America.

UUVs are marine platforms that are untethered and autonomous and often used for a variety of applications, including national security and ocean exploration. The robots selected for this study belong to the smallest class of vehicles called micro-UUVs, which have a diameter of six or fewer inches.

Detection, classification and tracking of ships are important tasks for improving port security and the security of coastal and offshore operations, explains Kristen Railey, who led the study as a Draper Fellow. «However, identifying UUV signatures and using those signatures to estimate a UUV’s speed for passive tracking is a relatively unexplored research area in comparison to other marine vessels.»

A state of the practice technique for identifying the presence of ships is by analyzing passive acoustic data with the Detection of Envelope Modulation on Noise (DEMON). The DEMON method, which operates by filtering propeller noise, varies by vessel, and can be challenged in a noisy and dynamic environment such as the shallow waters of harbors.

In the study, the authors set out to isolate and characterize motor noise, so they focused on brushless DC (BLDC) motors because of their prevalence in UUV propulsion systems. They designed a passive acoustic, high-precision method for estimating a micro-UUV’s propeller rotation frequency.

In field experiments, the new method outperformed the DEMON algorithm. When boats passed by the UUV, the new method could detect the motor noise, but the DEMON spectrum was dominated by the interfering boats’ propeller noise.

Quieter UUVs could have many benefits, the researchers explain in their paper. «Understanding the origins of acoustic noise in autonomous platforms can inform quieter UUV propulsion design to avoid interference with onboard sensors and disturbance to marine life. In the future, based on these findings, quieting techniques for BLDC motors in UUVs can be compared and assessed.»

While the current work is focused on micro-UUVs, the new method can apply to other robotic platforms that are powered by mass-manufactured BLDC motors. Brushless motors are found in electric vehicles, hybrid vehicles, personal transporters and electric aircraft.

Co-authors of the journal paper include Railey, a Ph.D. candidate in mechanical and ocean engineering at Massachusetts Institute of Technology (MIT) / Woods Hole Oceanographic Institute (WHOI); Henrik Schmidt, Railey’s academic advisor and a professor of mechanical and ocean engineering at MIT; and Dino DiBiaso, a computer scientist, systems engineer and distinguished member of the technical staff at Draper.

MIAMI, Jan. 25, 2021 /PRNewswire/ — Carnival Cruise Line today released plans for additional ship deployments as it continues to refine its phased in approach to a return to guest operations for 2021, resulting in some ship-specific cruise cancellations and movements.  Those plans include:

• Related to already-announced dry dock plans for Carnival Magic, Carnival Paradise and Carnival Valor, those ships’ return to operations will be delayed until November 2021. Consequently, voyages on Carnival Magic from Norfolk (embarkations from Sept. 29-Oct. 30), Carnival Paradise from Tampa (embarkations from June 5-Oct. 28) and Carnival Valor from New Orleans (embarkations from Sept. 16-Oct. 28) have been cancelled.
• Carnival Miracle’s planned seasonal service from San Diego has been suspended until further notice, and sailings out of San Diego that were available for sale through April 2023 have been cancelled, with the exception of seven voyages to Hawaii, which will move to Long Beach.
• Carnival Radiance’s dry dock and transformation has been moved to September, with a planned arrival to Long Beach in November 2021.
• With Carnival Miracle’s reposition to Long Beach, the ship will assume the three- and four-day itineraries for Carnival Radiance from May 3-Nov. 1, 2021 as well as the seven Hawaii Carnival Journeys referenced above. In addition, Carnival Miracle will launch a new program of four- and five-day cruises to Mexico during the winter season, beginning November 2021 and continuing through April 2023.

Carnival is advising guests and travel agents of these changes.  Where possible, West Coast guests are being accommodated in a transfer to Carnival Miracle (from Carnival Radiance), or the retention of their Hawaiian itinerary via a Long Beach embarkation instead.  With this change, Carnival will eventually run a three-ship operation from its port facility at Long Beach:  Carnival Panorama sailing seven-day Mexican Riviera itineraries and Carnival Radiance operating three- and four-day  itineraries year-round, with Carnival Miracle operating four- and five-day Mexico and 14-day Hawaii itineraries during the winter.

«Like so much about this current global situation, we are adapting our plans as circumstances evolve and we are able to confirm alternatives.  We are disappointed that our return to seasonal ports like Norfolk and San Diego has been impacted and appreciate the support of those port partners and communities.  The support of our guests, travel agents, ports and business partners has truly been overwhelming as we work through this situation,» said Christine Duffy, president of Carnival Cruise Line.

LJUBLJANA, Slovenia, Jan. 25, 2021 /PRNewswire/ — The Slovenian Tourist Board’s key PR and marketing focus on authentic and sustainable tourism has led to the country being included in many global media’s picks of the top travel destinations to visit in 2021.

Media outlets from across the world praised Slovenia’s sustainable tourism initiatives, particularly the Slovenia Green Scheme, which now has over 100 members. Slovenia’s popularity also proves that sustainability will be key to earning the trust of early foreign travellers following the global pandemic. 

MSc. Maja Pak, Director of the Slovenian Tourist Board: «The exposure of Slovenia as a sustainability-oriented tourist destination in such high-profile global media outlets is a great success and the result of many years’ active and systematic acceleration of sustainable tourism and cooperation with influential foreign media companies.

This is excellent exposure for Slovenia, especially since it contributes to Slovenia’s additional global positioning as a leading country in sustainable tourism, which will be one of the key advantages in tourism recovery after the COVID-19 pandemic.»

Last week, Condé Nast Traveller, became the latest publication to praise Slovenia’s efforts, placing it in a list of their top ten sustainable destinations in the world to visit in 2021.

Slovenia was chosen among top ten recommended destinations or, as stated in the article, «positive-impact escape ideas». An image of Bled Island is featured in the article, while Slovenia is presented as a Central European country with exceptional natural assets, picturesque landscape and numerous attractions.

Ljubljana is mentioned as being a welcoming and walker-friendly capital, as well as an attractive destination for eco-minded city breaks. The article highlights the high percentage of Slovenia’s protected landscape marked by vibrant diversity from the Alpine peaks, ancient forests, Karst plateaus, the Pannonian plains’ vineyards and thermal waters to the Adriatic Coast.

In recent weeks, leading British media including The Financial Times, The Guardian and The Sun have all placed Slovenia within their recommended destinations for 2021, while American outlet Forbes named Slovenia a bucket list destinations for wine-lovers. In late 2020 Slovenia was named one of Conde Nast Traveller’s best holiday destinations for 2021 and Bled was named one of the world’s ten best travel experiences in Lonely Planet’s annual Ultimate Travel List.
