Pakistan vs Afghanistan, Headingley Cricket Ground: Leeds weather Update on Saturday

first_imgRiding high on confidence after two back-to-back wins, Pakistan will look to carry on the winning momentum when they face Afghanistan in their crucial World Cup encounter at Headingley on Saturday.A win against Afghanistan will keep Pakistan in the hunt for the semifinal race. With seven points from seven games, Pakistan need to win both their remaining matches and hope for favourable results in matches of other teams too to make it to the top four by the end of the tournament.After their defeat to India, the Green Brigade had to face harsh criticism, both from fans and former cricketers. However, they kept aside all those negativities and registered thumping wins over South Africa and New Zealand.Their last win against the Black Caps would have bolstered their confidence immensely, considering the kind of performance they came out with against the Kiwis who were one of the two unbeaten sides in the tournament till then.Their bowling looks in firm form with Mohammed Amir, Shaheen Afridi and Wahab Riaz all chipping with crucial wickets. Their batting has also been bolstered by the inclusion of Haris Sohail who has contributed heavily in Pakistan’s last two wins. Also, with Babar Azam coming to his usual best, one can expect Pakistan to outstage Afghanistan.WEATHER FORECAST (Accuweather screengrab) (Accuweather screengrab)Afghanistan, on the other hand, have not been able to register a single win in the tournament so far. Their bowling has looked ok with all their spinners performing. But it’s their batting which has let them down in all the matches. The batsmen just have not been able to score and it has been a cause of concern for them.advertisementHowever, with nothing to lose, Afghanistan would hope to enjoy their game and come out with a surprise win against Pakistan, thus hampering their chances of making it to the knockout stage.Squads: Pakistan: Sarfaraz Ahmed (c, wk), Asif Ali, Hasan Ali, Shaheen Afridi, Mohammad Amir, Babar Azam, Mohammad Hafeez, Mohammad Hasnain, Imam-ul-Haq, Shadab Khan, Shoaib Malik, Wahab Riaz, Haris Sohail, Imad Wasim, Fakhar ZamanAfghanistan: Gulbadin Naib (c), Noor Ali Zadran, Hazratullah Zazai, Rahmat Shah (wk), Asghar Afghan, Hashmatullah Shahidi, Najibullah Zadran, Samiullah Shinwari, Mohammad Nabi, Rashid Khan, Dawlat Zadran, Aftab Alam, Hamid Hassan, Mujeeb ur Rahman, Ikram Ali Khillast_img read more

Scientists harvest energy from beams selfinduced selfsustaining vibrations in airflow

first_imgThe energy harvester consists of a carbon fiber beam with a piezoelectric sensor and stepper motor to adjust the angle of attack of the airflow in the wind tunnel. Unlike previous designs, the system does not require a secondary vibrating structure because the beam itself vibrates, reducing the volume of the harvester and increasing its efficiency.

Zakaria, et al. “Experimental analysis of energy harvesting from self-induced flutter of a composite beam.” Applied Physics Letters. DOI: 10.1063/1.4926876 Journal information: Applied Physics Letters © 2015 Phys.orgcenter_img The researchers, Mohamed Y. Zakaria, Mohammad Y. Al-Haik, and Muhammad R. Hajj from the Center for Energy Harvesting Materials and Systems at Virginia Tech, have published a paper on the new energy-harvesting method in a recent issue of Applied Physics Letters.”The greatest significance of the work is the reduction of the volume of the harvester, which translates to an increase in the power density, by eliminating the need for a secondary structure to be attached to the beam,” Zakaria said. “This reduction is important in the design of very small harvesters that can be used to develop self-powered sensors.”The research shows that subjecting a flexible beam to wind at the right angle of attack can cause the beam to bend so much that the beam’s “flutter speed” is significantly reduced. A large degree of bending also induces a change in the beam’s natural frequencies that basically results in a synchronization of the beam’s bending and twisting frequencies. Specifically, the beam’s second bending frequency and torsional frequency coalesce, resulting in “self-induced flutter” of the beam. Complex aerodynamic effects ensure that the vibrations are self-sustaining, allowing for continuous energy harvesting.The researchers demonstrated the design using a flexible cantilever beam with a piezoelectric transducer, which they hung from the ceiling in a wind tunnel. They found that the amount of energy harvested depends on a combination of factors, including the wind speed and the angle at which the wind hits the beam. At a wind speed of 10 m/s and 5.4° angle, the method can harvest approximately 0.3 mW of power. Although the researchers plan to improve the power levels, even this small value can be used to power individual sensors, which, as Zakaria explained, have a wide variety of applications.”Future monitoring of different systems and platforms such as air and water systems, structures, vehicles, infrastructure, etc., as well as secure data transmission and reception from these sensors, will require the use of hundreds or thousands of sensors, data loggers and hardware components,” Zakaria said. “The ability to integrate energy harvesters within these sensors or data loggers to develop such self-powered instruments is very much needed to enable their use without the need to replace batteries on a regular basis.”In the future, the researchers plan to design even smaller beams with specific geometries and capabilities, as well as to improve the performance of the piezoelectric elements.

(Phys.org)—In an attempt to harvest the kinetic energy of airflow, researchers have demonstrated the ability to harvest energy directly from the vibrations of a flexible, piezoelectric beam placed in a wind tunnel. While the general approach to harvesting energy from these “aeroelastic” vibrations is to attach the beam to a secondary vibrating structure, such as a wing section, the new design eliminates the need for the secondary vibrating structure because the beam is designed so that it produces self-induced and self-sustaining vibrations. As a result, the new system can be made very small, which increases its efficiency and makes it more practical for applications, such as self-powered sensors. Explore furtherlast_img read more

Eco Parks car painting festival sees stellar response from auto enthusiasts

first_imgKolkata: The three-day car painting festival at Eco Park has evoked great response among young car owners.The motto behind painting cars, which has become a popular form of art, is to construct a bridge between automobile and art and also to ensure that the owners maintain their cars and do not drive recklessly. The theme of the festival is closely associated with Chief Minister Mamata Banerjee’s Safe Drive Save Life programme, where stress is laid on careful driving. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseA group of ‘cartists’ have arrived at the city from Jaipur and are painting modern cars. Many young vintage car owners have brought their vehicles to paint them in beautiful and vibrant colours. The art of car painting has become famous globally after gaining popularity in USA. The cartists said there was tremendous enthusiasm among car owners in Kolkata to paint their vehicles. The paintings are done free of cost. They said: “We want the owners to maintain their cars. They should not drive recklessly and damage the vehicles.” They take one day to complete a vehicle. One or more artists work on one vehicle at a time. The paintings include abstract art, scenery or scenes from a poem or a play. The cartists will also paint two walls near the medical clinic situated inside Eco Park.last_img read more
