Measurement of Prandtl number as a function of Richardson number avoiding self-correlation

first_imgThe empirical dependence of turbulence Prandtl number (Pr) on gradient Richardson number (Ri) is presented, derived so as to avoid the effects of self-correlation from common variables. Linear power relationships between the underlying variables that constitute both Pr and Ri are derived empirically from flux and profile observations. Pr and Ri are then reconstructed from these power laws, to indicate their interdependence whilst avoiding self-correlation. Data are selected according to the stability range prior to regression, and the process is iterated from neutral to higher stability until error analysis indicates the method is no longer valid. A Butterworth function is fitted to the resulting Pr (-1)(Ri) regression to give an empirical summary of the analysis. The form suggests that asymptotically Pr (-1) decreases as Ri (3/2). Scatter in the data increases above Ri similar to 1, however, indicating additional constraints to Pr are not captured by Ri alone in this high stability regime. The Butterworth function is analytic for all Ri > 0, and may be included in suitable boundary-layer parameterisation schemes where the turbulent diffusivity for heat is derived from the turbulent diffusivity for momentum.last_img read more

Committee Focuses on Fort Hancock Repair, Future Use

first_imgBy John BurtonSANDY HOOK – In what is expected to be a two- or three-year process, a citizens’ committee studying the future of Fort Hancock and its historic structures has begun its work.The National Park Ser­vice (NPS) has convened a 20-member committee from a variety of fields to look at the possible future use and pre­servation of 38 structures at the former military installation, located at the northern tip of Gateway National Recreation Area at Sandy Hook.Officers Row at Fort Hancock after Super Storm SandyMany of the location’s structures, most of them more than a century old, have been deteriorating. “Some of these buildings, it may be too late to save already,” NPS spokesman John Harlan Warren said.Warren said Linda Canzanelli, superintendent for Gateway recreation areas, told the committee as they gathered for the first time last week it was “the last best chance to save Fort Hancock.”“I think that sums it up quite nicely,” Warren said.Warren also acknowledged “There will be little or no NPS money for the long-term preservation.”Among the committee members is Lynda Rose, president and chief operating officer of the Eastern Monmouth Area Chamber of Commerce. Rose said, while it was “way too soon” to be talking about possible strategies for the location’s future, “there are some wonderful ideas out there.”Eventually, “like any good strategy session, we’ll put everything on the table and then talk about what’s possible, what’s not possible and why isn’t it possible,” Rose said.Another committee member, Mary Eileen Fouratt, executive director of the Monmouth County Arts Council, the arts education and advocacy organization headquartered in Red Bank, is looking to “see where the possibilities are.“I just think it is a beautiful place and has such a great history,” Fouratt said, “I’d like to see something happen other than buildings falling down.”Rose said that as a chamber of commerce president she would “like to see some hotels out there. I’d like to see some B and Bs out there.” But, she would also like to see arts venues and educational components and all should be accomplished while keeping with the park’s natural beauty and environment in mind.“There are ways to do things: wrong ways and right ways,” she said.While the committee is the first convened by the park service under the Federal Advisory Committee Act of 1972 (FACA) to investigate ways to rehabilitate the former Army fort’s structures, it is not the first time the NPS has tried to work out a strategy to preserve them by way of a public/private partnership.The park service struck a deal with a private developer in 1999 to renovate the buildings that the developer then would lease out for a variety of for-profit and not-for-profit uses. The plan became quite controversial. A bitter battle lasted for about 10 years with opponents going to federal court to block the plan, alleging it would allow for the commercialization of parkland intended for the public’s recreational use. Proponents, including the park service, contended the plan was a means of preserving a historic resource without relying on taxpayer dollars.The park service eventually canceled the agreement when the developer failed to obtain the necessary financial backing to move the project forward. Only two buildings were renovated.Rose said the public/private partnership “can be done,” pointing to other national park areas, including The Presidio and Cavallo Point, located in Northern California. Those locations are “very respectful of the community, of the property and more important, the history,” of the sites, she said.During the committee’s first meeting last week at the Ocean Place Resort in Long Branch, George Moffatt offered a different view. “The only use for those buildings should be educational and recreational,” he said.Moffatt was a board member of Save Sandy Hook, the group that had opposed the park service’s plan to work with the developer.Prior to Super Storm Sandy – which resulted in the park being temporarily closed due to damage – fort buildings were used by educational, nonprofit and government entities. While sections of the recreation area sustained considerable storm damage, Fort Hancock managed to escape the worst of it.Work to fix and rehabilitate the park is ongoing, but major projects, including the repair of the sewerage system, will have to wait until money from the Sandy relief bill, signed Tuesday night by President Obama, makes its way through the funding system, Warren said.Committee members, who are volunteers with experience in science, real estate, cultural arts, education and local and county government, are expected to meet four to six times a year during the next two to three years to devise recommendations for the site.last_img read more

Behind enemy lines, 49ers at Washington: 5 questions with Post reporter

first_imgSANTA CLARA — Here is what Washington Post reporter Les Carpenter said of Sunday’s 49ers visit to Washington:Question: Why did Bill Callahan’s succession of Jay Gruden immediately produce a win, or was this more about the winless opponent?Carpenter: The easiest answer to this is to say the Redskins were playing a team ranked last in the league in almost every meaningful category. That said, they still almost blew the game and won only because Miami’s coach, Brian Flores, went for two …last_img

How I Determined My Three Words for 2016

first_img Essential Reading! Get my 3rd book: Eat Their Lunch “The first ever playbook for B2B salespeople on how to win clients and customers who are already being serviced by your competition.” Buy Now Today I recorded a podcast with Jeffrey Gitomer. He asked me the question about how I set up my Three Words for 2016.Ken Wilber is likely the greatest mapmaker of all time, having created a map of the entire universe including human psychological and cultural development. If that sounds like an exaggerated claim, I assure you it isn’t.The last time I was with Ken Wilber, I asked him the secret of making maps.The following is what Ken told me to do. He told me to write everything I could think of as it pertained to a map I was creating. Then he told me to spend time bundling these ideas into the logical categories that present themselves. Once those categories were bundled together, move up a level and see if there are other natural ways to bundle things together. You want as few pieces as necessary, and as many as you need. It sounds easier than it is, especially after you have gone through the process a few times.And this is how I established my Three Words for 2016.I made a list of goals and gaps. I looked at my successes from the past year and decided to increase my goals massively in 2016. And then I looked at the differences between my current performance and my future goals. I started to bundle together ideas.Growth: As I looked at my work, I recognized that there were areas where I needed to develop and increase my skills and my results. As I bundled those together, the word “growth” was a common theme. It was in every category of goals. It made sense to start there.Multiplier: Recognizing that time is our only non-renewable resource, I acknowledged that there’s nothing I can do to add more hours to my day. To me, this meant I needed a “multiplier.” I still only have one hour a day to workout at the gym. Limited time, in this and other areas, requires that I do things that multiply the outcome of my efforts.Focus: There were some goals and gaps that I recognized needed more of my time and attention. There are so many things I want to do, but there is not enough time to do all of them. As I looked at these, the common theme was “focus.” Focus is a narrowing. It’s concentration of attention and energy. It also means eliminating some things that are outside of what’s most important.After I had finished developing these themes, I went back over my goals and outcomes for 2016 to work them through the Three Words framework. I applied these ideas to the revised vision of my 2016 plan. The iteration is important. It solidifies things.You can use this methodology in any area of your life. If you haven’t used the Three Words methodology, I recommend it. And if you’ve already chosen your three words, run back through your goals and dreams and make sure they’re all aligned with your themes.last_img read more

Alexander Zverev sets up Thiem showdown after another five-set grind

first_imgAlexander Zverev had not played a five-set match in two previous visits to Roland Garros. On Sunday he completed his third in five days, guided by his Russian-born father, to beat the talented young Muscovite Karen Khachanov 4-6, 7-6 (4), 2-6, 6-3, 6-3 in just under three and a half hours.To borrow from Fred Trueman, if the 21-year-old Zverev does win this French Open “he’ll be bloody tired”, although he gave no indication he was about to collapse in a heap on Court Suzanne Lenglen after breaking down the resistance of the 22‑year‑old Khachanov, the world No 38.The two youngest players left in the draw needed all the energy of youth on a hot, still day. Zverev, seeded second here in Roger Federer’s absence, will take 11 hours and 46 minutes of muscle-sapping baggage into the quarter-finals against the bustling Austrian Dominic Thiem, who stopped him in the third round two years ago.That might not be long by the standards of the past decade but, cumulatively, it is a significant workload, and one Zverev says he is still getting used to, although he bridles at suggestions he lacks staying power over five sets – and he now has a respectable 6-6 record.Asked if he thought Khachanov was flagging at the end, he said: “At the beginning of the fourth I thought ‘OK I can turn this match around’, especially when I saved a few break points. He’s a very fit player, so I don’t think it’s that easy to make him tired. Obviously playing five sets, anyone would get tired a little bit.”He added: “I know who I am. It’s not about learning any more. It’s about trying to find a way and trying to win. That’s what I am able to do in the last few matches, and I’m very happy about that. I’m very happy about being in the quarter-finals here, going the hard way, going the distance every single time and showing myself, showing everybody, that I can play for as long as I need to. If you’re mentally fatigued then something is wrong with you. Physically, it’s not easy to play back‑to‑back‑to‑back five-set matches – but I will manage it somehow.” Alexander Zverev Reuse this content Share on WhatsApp French Open Tennis Share on LinkedIn Share on Messenger Share on Twitter news Topics Support The Guardian Thiem, who outlasted a weary Kei Nishikori 6-2, 6-0, 5-7, 6-4, is one of the busiest and quickest players on clay. There will be no rest for Zverev when they return on Tuesday.“That’s the match-up most of the fans in Germany and Austria were hoping for when they saw the draw,” Thiem said. “We just played in Madrid [where Zverev won in the final]. He’s an amazing player – probably now the third-best after Rafa [Nadal] and Roger.”He did not expect stamina to be a problem for Zverev. “He has an amazing team [including Andy Murray’s former conditioner, Jez Green]. He’s super fit.”For Zverev to become the first from his country to win the title since Henner Henkel beat Bunny Austin in 1937, he has to win three more matches. The most daunting challenge will be in the final, barring calamity, against the greatest player in history on clay, the 10-times champion Nadal.To eliminate the Spaniard from the equation, Zverev’s countryman Maximilian Marterer will have to pull off the upset of the tournament, year, decade and millennium on Monday – and then all bets are off. The 22-year-old left-hander from Nuremberg, ranked 70 in the world, can only hope Nadal stubs his toe on the morning of the match.In the top half of that side of the draw, Novak Djokovic served his way through some scrappy moments to a 6-3, 6-4, 6-2 win against the Spaniard Fernando Verdasco, whose blistered feet in the second set can hardly have added to the experience over two hours and 25 minutes on Chatrier.Having dropped just one set on his way into the second week, he said courtside: “I like my connection with the public here. He’s a clay specialist and it wasn’t an easy match. He stayed concentrated with a good deal of intensity.”Djokovic has an unexpected opponent in the quarter-finals – the 25‑year‑old Sicilian world No 72, Marco Cecchinato, who upset David Goffin 7-5, 4-6, 6-0, 6-3, and becomes the lowest-ranked man to get this far here since Ernests Gulbis in 2008.

Trudeau government preparing for longawaited Indigenous Languages Act

first_imgMartha Troian APTN InvestigatesThe federal government is finally getting ready to live up to one of its promises made to Indigenous people on the campaign trail.Canadian Heritage will spend up to $100,000 for the next 10 months to hire a supplier to assist and provide policy advice in the development and drafting legislation to promote, preserve and revitalize Indigenous languages.To date, the government has the intention of awarding this Advance Contract Award Notice to a former General Counsel with the Department of Justice, if no other suppliers step forward. J. Paul Salembier’s name is on the tender notice.During his 2015 campaign, then-Liberal leader Justin Trudeau pledged substantial new funding to communities to support Indigenous languages and culture.As prime minister in Dec. 2016, Trudeau announced the government would work with national Indigenous political organizations to develop legislation to create an Indigenous languages Act.Read: Trudeau doubles-down on promises made to First Nations, pledges new Indigenous languages lawIn June 2017, Canadian Heritage, the Assembly of First Nations (AFN), Inuit Tapiriit Kanatami and the Metis Nation launched the co-development of Indigenous languages legislation. Since the announcement, engagement sessions were held with the department, national Indigenous organizations, Indigenous experts and with language keepers.In Dec. 2017, the AFN passed a resolution named the Support for Continued Co-Development Work on the Indigenous Languages Act calling on the federal government to officially recognize Indigenous languages like the English and French languages. Since the 1980s, AFN has passed close to 20 resolutions dealing with language preservation.According to the latest census, there are 70 Indigenous languages in Canada with 260,000 language speakers. Several of these Indigenous languages are considered endangered.‘The masters of the long promise’Quebec NDP MP Romeo Saganash hopes the government will make Indigenous languages official and that it’s not just mere window dressing.NDP MP Romeo Saganash“I think time is running out for them, like other promises that they’ve made,” Saganash said about Trudeau’s campaign promises.“It’s a lot of talk and no action for most of the files…I call them ‘the masters of the long promise’ because that’s what it looks like to me.”Saganash said he was not advised of the contract coming out of Canadian Heritage despite being an Indigenous speaker himself in the House of Commons.Earlier this year Saganash spoke his Cree language during a Procedure and House Affairs Committee proceeding, which required the MP to first receive permission from the House of Commons. The committee is looking into how Indigenous languages can be heard and understood in Parliament.Read: Committee considers Indigenous languages use on Parliament Hill Punished for speaking the languageIndigenous leaders say the perilous state of Indigenous languages has its roots in government policy and the residential schools system.More than 150,000 children entered these church-run, government-funded residential schools, many of them were regularly punished if they were caught speaking or practicing their language and culture.In June 2008, then Prime Minister Stephen Harper apologized to survivors, acknowledging the profoundly negative and damaging impacts of residential schools on people, language and culture.The final report of the Truth and Reconciliation and its Calls to Action, released in Dec. 2015, urges all levels of government to create change as a means to correct past wrongdoings and includes specific calls relating to languages.Susan Blight, a member of the Couchiching First Nation in northwestern Ontario and an Ojibwe language learner is concerned this process will become bureaucratic and less about the people themselves.Susan Blight is a member of the Couchiching First Nation in northwestern Ontario and an Ojibwe language learner.“It needs to be designed by our people, by individual nations for individual nations,” says Blight about the proposed legislation.A media spokesperson with Canadian Heritage said currently the department along with several national Indigenous organizations are “developing common and distinction-based legislative elements” that will form the department’s community-based engagement process.This process will commence late spring to the end of summer.The government intends to table the legislation in Parliament before the end of the current mandate.When asked if the government intends to make Indigenous languages official in Canada, the spokesperson did not directly answer.The contract for this bid will run 10 months from the time awarded to March 31, 2019. So far the department has not received any formal expressions of interest in the contract.Bidding for the contract closes on May [email protected]@ozhibiiigelast_img read more

Chamber of Commerce VP joins delegation to Alberta supporting Kinder Morgan

first_imgThe trip occurred with less than two weeks until Kinder Morgan’s May 31st self-imposed deadline, when it will make a decision to scrap or proceed with the project, depending on whether it feels it has enough support from the federal government. EDMONTON, A.B. — The First Vice President of the Fort St. John & District Chamber of Commerce, Julie Ziebart, was among 100 delegates from across B.C. who travelled to Edmonton on Thursday in support of Kinder Morgan’s Trans Mountain pipeline expansion.Ziebart was one of the group of officials that included Greater Vancouver Board of Trade and the BC Chamber of Commerce, and brought members’ concerns and support for the Kinder Morgan project to the forefront as part of the trip, titled ‘Federation Flight: Rebuilding Confidence in Canada.’ Federation Flight also included business, community, Indigenous and labour leaders, and was aimed at reinforcing the fundamental partnership that is the Canadian federation. Chamber of Commerce Executive Director Lilia Hansen said she believes that, “The Chamber’s greatest benefit is the power to advocate for our members at all levels of government, attend high level meetings such as this one where we can have face to face conversations with decision makers, and build bridges that will benefit our community.”last_img read more
