Artificial intelligence to measure collaborative capacity of students

14 hours ago e-learning.

Tecnalia works on the development of semantic descriptors applied to collaboration indicators on e-learning platforms.

E-learning platforms are becoming particularly relevant now that training is a key factor for people, and both companies and universities or training centres are aware that they are going to be an essential training pillar in the future, thanks to their flexibility, dispersion and adaptation to the different study rates of students. One of the key aspects is the potential of collaborative learning between students; the ability to resolve a problem between several people, divide and spread out the work and learn from it, has a clear advantage over individual learning.

It is essential to be able to measure the degree of collaboration of each student, and have transferable metrics and indicators so that any e-learning platform can monitor the degree of collaboration of its students. In this way, this platform can generate recommendations to encourage collaboration between its members, or correct inappropriate trends in a collaborative learning process.

Artificial Intelligence techniques are used to obtain this data and hence generate the opportune recommendations: Machine Learning and Data Mining, which provide metrics and indicators that are transferable to any e-learning programme, through semantic techniques that can be used on any learning platform for adaptive and recommendation purposes.

Alcoa, VSMPO in joint venture to develop aerospace products

NEW YORK (Reuters) - U.S. aluminium company Alcoa Inc (NYS:AA) has formed a joint venture with Russia's VSMPO-Avisma Corp (MCX:VSMO), the world's No. 1 titanium producer, to develop high-end aerospace products to feed growing demand from the sector, Alcoa said on Tuesday.

The two firms will collaborate on manufacturing high-specification products, such as landing gear and forged wing components, at Alcoa's Samara facility in Russia, where it makes flat-rolled products, forgings and hard alloy extrusions.

Few other details were available, although a statement said the new venture is expected to be operational in 2016.

The news comes as Alcoa shifts its focus downstream to value-added aluminium products, aimed at the aerospace and automotive sectors, as it cuts its exposure to weak primary metal prices.

In the Samara venture, VSMPO will increase output and gain access to forging equipment, marking the company's continued shift towards value-added products, general director Mikhail Voevodin said in the statement.

Alcoa has previously projected the aerospace market will grow by 9 percent to 10 percent this year. While the outlook for aerospace industry growth is encouraging, the race to produce high-strength, lightweight and low-cost materials in planes has accelerated and the global aluminium industry is facing intense competition from new carbon composites in aerospace.

The move comes after Alcoa expanded its aluminium lithium capacity in the United Kingdom earlier this year. The firm is also building a new U.S. facility in Indiana to produce 20,000 tonnes per year of aluminium lithium.

Aluminium lithium alloy is used in forgings, sheet and plate applications in airplane wings and fuselage components. Alcoa says it is more fuel efficient and lower-cost than carbon composites.

The Indiana facility is expected to come onstream by the end of next year.

PPG Aerospace Designs Innovative Cockpit Windows For Dassault Falcon 5X Jet

HUNTSVILLE, Ala.--(BUSINESS WIRE)--

PPG Industries (PPG) aerospace transparencies group has designed uniquely shaped, lightweight glass windshields and side cockpit windows for the new Dassault Falcon 5X business jet that accentuate the cockpits aerodynamics and afford expansive visibility.

According to Mark Hood, PPG global market director for general aviation transparencies, PPG is under contract with Dassault Aviation to provide production and spare windshields and side cockpit windows, which are the largest for a Falcon jet.

Dassault Aviation wanted curved glass transparencies having the lightest weight possible, and our unique bending and materials expertise enabled us to propose designs exceeding their expectations, Hood said. We are proud we were selected and look forward to growing our relationship with Dassault Aviation.

Arthur C. Scott, PPG global market director for commercial transparencies, had been in Hoods current role when PPG secured the business. Scott said, This is the first Dassault airplane for which we will supply production cockpit windows, and we are pleased we will be able to join Dassault in creating a great new aircraft.

The windshields and side cockpit windows are designed with three plies of HERCULITE(R) II chemically strengthened glass to be strong and lightweight and resist impact by a 4-pound bird at 350 knots. The aircraft will not have windshield wipers, so the windshields and windows have SURFACE SEAL(R) coating to enhance water shedding for visibility. The heating system has been designed to meet challenging requirements including aesthetics and visibility.

Hood said PPG has completed qualification testing for Safety of Flight and is ready to begin production to support the program schedule as directed by Dassault. The windshields and windows will be made at PPGs Huntsville, Ala., plant.

Foot and mouth disease in sub-Saharan Africa moves over short distances, wild buffalo are a problem

PUBLIC RELEASE DATE:

22-Oct-2013

Contact: Jim Sliwa jsliwa@asmusa.org 202-942-9297 American Society for Microbiology

New research shows that in sub-Saharan Africa the virus responsible for foot and mouth disease (FMD) moves over relatively short distances and the African buffalo are important natural reservoirs for the infection. The study, published in mBio, the online open-access journal of the American Society for Microbiology, sheds light on how the type of FMD virus called SAT 2 emerged in sub-Saharan Africa and identifies patterns of spread in countries where SAT 2 is endemic.

"The data suggest that the common ancestor of all SAT 2 was in [African] buffalo. It's very clear that historically infections have moved from buffalo to cattle," says corresponding author Matthew Hall of the University of Edinburgh in Scotland.

Foot and mouth disease (FMD) is devastating to livestock all over the world, but it's a particular problem in Africa, where wildlife that harbor the virus are thought to pass it on to their domesticated cousins.

FMD strikes cloven-hoofed animals, presenting as a high fever, blistering in the mouth and feet, decline in milk production in females, and weight loss. Although most animals recover over the course of months, some die of complications from the disease. In wild buffalo, the disease is very rarely symptomatic and animals can be persistently infected for a period of several years. The SAT 2 serotype of the virus is endemic in sub-Saharan Africa, but it has crossed the Sahara and caused outbreaks in North Africa and the Middle East between 1990 and 2012.

In the hopes they could eventually predict future outbreaks, Hall and his colleagues wanted a better picture of the diversity of SAT 2 viruses in sub-Saharan Africa and how they move around from one location to another. They used 250 genetic sequences of the VP1 section of the genome from SAT 2 isolates taken from all over sub-Saharan Africa and tracked the appearance of the various unique 'topotypes' over the region.

Hall says the patterns in which the topotypes appear in different places gives strong support to the idea that the virus is spread by infected hosts in land movements over relatively short distances. What's more, African buffalo are an important "maintenance host", meaning they maintain a reservoir of the virus that can re-infect domesticated animals after time and culling has ended an outbreak among livestock. The relationships between the 250 sequences also indicate that it's possible the original source of the SAT 2 viruses that are now found in wild and domesticated animals was African buffalo.

To Hall, these results indicate that genetic tracking of viruses has a lot of potential for making inferences about viral spread and heading off future outbreaks.

Physician First Choice Now Offering IV Stem Cell Therapy for Numerous Medical Conditions with US Board Certified Stem …

Orange County, CA (PRWEB) October 21, 2013

The premier stem cell therapy clinic on the West Coast, Physician First Choice, is now offering IV stem cell treatment for numerous medical conditions. This includes stem cell treatment for Alzheimer's disease, Diabetes, Parkinson's, Liver Disease, Cardiac Disease, COPD and much more. The treatments are provided by US Board Certified Stem Cell Doctors and for more information call (888) 988-0515.

Stem cell therapy has become available for numerous medical conditions and can dramatically improve the patient's baseline. Increasing amounts of research are showing the benefits of IV stem cell therapy for conditions such as diabetes and COPD. Prior to stem cell therapy, these conditions could be managed with traditional medications, but the disease itself could not be altered. With stem cell therapy, that possibility exists.

The Board Certified stem cell doctors at Physician First Choice have over 20 combined years of experience working with patients for both stem cell injection treatment and IV therapy. The clinic treats patients at multiple Southern California locations along with an international location in Mexico. Patient treatment is performed by the same US Board Certified doctors before, during and after therapy to ensure continuity of care.

The program in Mexico involves four days worth of treatment at a first rate clinic, and patients stay at a beautiful hotel with transportation included. IV stem cell therapy is performed along with growth factor treatments to enhance the effect of the bone marrow stem cells.

For conditions such as multiple sclerosis, Alzheimer's or Parkinson's, watching a loved one deteriorate can be disheartening even when the best care is received. Physician First Choice has been having excellent results with IV stem cell treatment for diabetes and these conditions, and the program has been growing exponentially as a result.

The 4 Day Stem Cell Therapy IV Program is offered as a package. Transportation to and from San Diego is included along with the Hotel Stay, All Medical Treatment, Breakfast Each Day, and Transportation between the Gorgeous Hotel and the Stem Cell Treatment Facility. Patients must be approved for program inclusion with a full medical record review and evaluation by the Southern California doctors.

To inquire about program inclusion for IV stem cell therapy, call Physician First Choice at (888) 988-0515.

Late bishop a 'humble priest' whose spirituality touched thousands

Rockville Centre, N.Y.

The "humility, sense of humor and, above all, spirituality" of retired Auxiliary Bishop James J. Daly of Rockville Centre, who died Oct. 14, "touched thousands and thousands of the faithful in a very deep and personal way," said the head of the diocese.

Bishop William Murphy said the late auxiliary bishop, who was 92 years old, was "truly a trailblazer and visionary during the early formative years of this diocese."

A funeral Mass was celebrated for Daly on Friday at the Cathedral of St. Agnes, followed by burial at St. Boniface Cemetery in Elmont, N.Y.

Murphy was the main celebrant, and concelebrants included Cardinal Timothy Dolan of New York and several priests. The homilist was Msgr. James McNamara, episcopal vicar of the diocese's central vicariate and pastor Our Lady of the Miraculous Medal Parish in Point Lookout.

In an Oct. 15 statement, Murphy noted that "so many of the people of God of this great diocese" experienced the late bishop's "witness as humble priest and later as auxiliary bishop."

"Please do not let up, as you fill our cups with hope as well as knowledge." - A donor from Seetonk, MA

Daly "was always a calm, peaceful and reassuring presence," he added.

Born Aug. 14, 1921, in the Bronx and raised in Queens, Daly was ordained a priest of the diocese of Brooklyn in 1948. He served in the Brooklyn diocese and then Rockville Centre as an assistant pastor, as a teacher and as procurator at the diocesan seminary, Immaculate Conception in Huntington.

Cygnus cargo craft readies to leave space station

5 hours ago This photo courtesy of NASA shows the Orbital Sciences Corporation Antares rocket, with the Cygnus cargo spacecraft aboard, as it launches on September 18, 2013, NASA Wallops Flight Facility, Virginia

A private cargo ship built by Orbital Sciences Corporation is preparing to leave the International Space Station early Tuesday and burn up on re-entry into Earth's atmosphere, NASA said Monday.

The Cygnus spacecraft is scheduled to detach from the orbiting research outpost at 1000 GMT Tuesday and leave the ISS an hour and a half later.

"Orbital engineers then will conduct a series of planned burns and maneuvers to move Cygnus toward a destructive re-entry in Earth's atmosphere," NASA said in a statement.

Orbital said Cygnus is expected to re-enter the atmosphere on Wednesday, October 23 at 1818 GMT over the Pacific Ocean east of New Zealand.

The unmanned spaceship attached itself to the ISS on September 29, marking the first successful demonstration mission of a cargo resupply flight by Orbital Sciences.

It is the fourth such mission by a private company to ferry supplies to global astronauts, a capacity the United States lost when the space shuttle program ended in 2011.

The California-based SpaceX, owned by entrepreneur Elon Musk, in 2012 became the first private enterprise to send its own cargo-bearing spacecraft to the ISS and back.

Both companies have billion-dollar NASA contracts to deliver cargo to the ISS on multiple missions over the coming years.

Unlike SpaceX's Dragon capsule, Cygnus cannot return to Earth intact and will be destroyed after its mission is complete.

Old volcanic rock to represent Victoria in space flight

A small piece of pumice that originatedduring the Taup eruption almost 1,800 years ago has been selected by aVictoria University of Wellington professor to go on a European space flight.

The pumice will accompany European Space Agency (ESA) astronaut Dr Alexander Gerst on a six-month mission to visit theInternational Space Station, which is currently orbiting Earth.

Dr Gerst is a formerVictoria University student, who studied under geophysicsprofessor Martha Savage at the Institute of Geophysics several years ago.

He will serve as a flight engineer on the mission, which is scheduled to leave Earth at the end of May 2014 and return six months later in mid-November.

He invitedProfessor Savage to contribute an item to take on the journey to the International Space Station and she selected a small, rectangular piece of pumice, measuring two and a half centimetres in width and weighing just over 14 grams.

I chose it because its lightweight andsmall, and beautifully represents the University and the highly regarded earthsciences programme we run here, which Dr Gerst was part of for a time, says Professor Savage.

She says being able to provide an item for the flight provides an exciting opportunity for Victoria University to be part of Dr Gersts first-everspace exploration.

Its also a reminder of the kind of things talentedstudents like Dr Gerst go on to achieve with a Victoria Universityeducation.

NASA reverses trajectory on Chinese ban – report

by Agence France-Presse Posted on 10/21/2013 1:00 PM |Updated 10/21/2013 1:00 PM

BEIJING, China NASA has reversed a decision to ban 6 Chinese scientists from a space conference, Chinese state media said, after prominent US astronomers vowed to boycott the meeting in a row over academic freedom.

The US space agency had barred them from participating in the meeting on exoplanets bodies outside the solar system in California in early November, saying it was legally obliged to do so because of their nationality.

A NASA committee has now written to the 6 to change course, China's official Xinhua news agency reported.

"We have since been able to clarify the intent of the referenced legislation and are pleased to inform you that this decision has been reversed and your paperwork is being reviewed for clearance," Xinhua quoted the letter as saying.

"We hope you will be able to join us," it added.

The initial decision to block the 6 led to an academic uproar and some leading US astronomers, including Yale University's Debra Fischer, announced plans to boycott the conference.

Geoff Marcy, an astronomy professor at the University of California, Berkeley, wrote in an email to the organizers: "The meeting is about planets located trillions of miles away, with no national security implications."

China's foreign ministry also blasted NASA's denial of the researchers' applications as discriminatory, arguing that politics should have no place at academic meetings.
