GE Global Research, the technology development arm of the General Electric Company (GE), today announced research that could significantly impact the design of future wind turbine blades. Utilizing the power of high-performance computing (HPC) to perform complex calculations, GE engineers have overcome previous design constraints, allowing them to begin exploring ways to design reengineered wind blades that are low-noise and more prolific power-producers.Partnering with the Sandia National Laboratories (Sandia) in Albuquerque, New Mexico, GE’s work focused on advancing wind turbine blade noise prediction methods. Aerodynamic blade noise is the dominant noise source on modern, utility-scale wind turbines and represents a key constraint in wind turbine design. Efforts to reduce blade noise can help reduce the cost of wind energy and increase power output. In fact, GE predicts a 1 decibel quieter rotor design would result in a two-percent increase in annual energy yield per turbine. With approximately 240GW of new wind installations forecasted globally over the next five years, a two-percent increase would create 5GW of additional wind power capacity. That’s enough to power every household in New York City, Boston, and Los Angeles, combined.“There’s no question, aerodynamic noise is a key constraint in wind turbine blade design today,” said Mark Jonkhof, Wind Technology Platform Leader at GE Global Research. “By using high-performance computing to advance current engineering models that are used to predict blade noise, we can build quieter rotors with greater blade tip velocity that produce more power. This not only means lower energy costs for consumers, but also a significant reduction in greenhouse gas emissions.” Jonkhof added: “Having access to Sandia’s supercomputer was invaluable in our ability to conduct these experiments and make discoveries that will bolster wind power’s potential. Access and availability to HPC resources offers a critical advantage to companies trying to compete in a global environment.”To ensure that GE’s wind blades do not pose noise issues today, airfoil level acoustic measurements are performed in wind tunnels, field measurements are done to validate acceptable noise levels, and noise-reducing operating modes are implemented in the control system. Better modeling will help maintain the current low noise levels while boosting output.“Sandia and other DOE national laboratories are using high-performance computing resources to tackle complex design problems in wind energy, such as reducing turbine blade noise to achieve significant reductions in cost-of-energy. Sandia helped GE gain valuable insights into blade noise mechanisms and how design engineers can improve their models,” said Matt Barone, of Sandia’s Aerosciences Department, formerly of the Wind Energy Technologies Department.GE’s testing involved Sandia’s Red Mesa supercomputer running a high-fidelity Large Eddy Simulation (LES) code, developed at Stanford University, to predict the detailed fluid dynamic phenomena and resulting wind blade noise. For a period of three months, this LES simulation of the turbulent air flow past a wind blade section was continuously performed on the Red Mesa HPC. The resulting flow-field predictions yielded valuable insights that were used to assess current engineering design models, the assumptions they make that most impact noise predictions, and the accuracy and reliability of model choices.“We found that high fidelity models can play a key role in accurately predicting trailing edge noise,” Jonkhof went on to say. “We believe that the results achieved from our simulations would, at the very least, lay the groundwork for improved noise design models.” [mappress]Press release, August 15, 2013; Image: GE

Margaret RobertsonPartner profits at Withers have soared by over 40% in a bumper year for the international firm, which announced it was furloughing staff in April.According to figures for the year ended 30 June, profit per equity partner rose by 42% to £501,000, while profit stands at £42.1m. Revenue is up 14% at £219.7m.Chief executive Margaret Robertson said: ‘Going into lockdown, we had a full pipeline of work and had experienced a very good financial year thanks to investments made in the prior few years. Although the final three months of the year were quieter in some areas, client demand actually grew in dispute resolution, technology and estate planning and structuring.‘This all led to a strong financial performance. We are approaching next year cautiously but, as a firm focused on private capital, we find our clients are very active in volatile times and we hope that will continue to fuel our growth.’ Withers originally furloughed 57 staff and 21 have now been brought back on a permanent basis. No salaries have been cut, however, and the decision was taken not to reduce or defer partner pay.The firm declined to comment on why it made use of the government job retention scheme..

WASHINGTON D.C., United States, CMC – The United States Citizenship and Immigration Services (USCIS) says six Caribbean countries are among 63 countries worldwide that are eligible to participate in two visa programmes this year.The H-2A and H-2B Visa programmes allow US employers to bring foreign nationals to the United States to fill temporary agricultural and non-agricultural jobs, respectively.The USCIS identified the Caribbean countries eligible to participate in the visa programmes as Barbados, Belize, the Dominican Republic, Grenada, Haiti and Jamaica.Generally, USCIS said it only approves H-2A and H-2B petitions for nationals of countries the Secretary of Homeland Security has designated as eligible to participate in the programmes. USCIS also said it may approve H-2A and H-2B petitions for nationals of countries not on the list if it is determined to be in the interest of the United States.Effective January 18, 2014, USCIS said nationals of the identified Caribbean countries are eligible to participate in the H-2A and H-2B Visa programmes.It said the notice does not affect the status of beneficiaries who currently are in the United States in H-2A or H-2B status unless they apply to change or extend their status. The USCIS said each country’s designation is valid for one year from January 18, 2014.Caribbean Media Corporation Share Sharing is caring!

The ‘sambung bayar’ practise is quite a regular thing among Malaysian motorist. Sambung bayar literally translates to “Continue Payment” in English, and this happens when a person is no longer able to pay his car or motorcycle loan, and somebody else steps up to continue payment for the loan while the car or bike remains in the original owners name.This is risky business for the original owner as the person who continues his payment may just up and leave with the owner’s car or motorcycle. This has caused the number of individuals black listed by financial institutions to rise. So the standard practise is for the owner to take a deposit for the car or bike.This has been happening for a while now, and the owner of the vehicle sometimes prefers the ‘sambung bayar’ method as he does not need to find someone to buy over his vehicle, which will take time while the owner continues to service the monthly payments.It is so popular that there are entire Facebook pages dedicated to it, you can click here to view a page on cars available for sambung bayar, or click here for a page on sambung bayar motorcycles.Well, the good days for those who practise sambung bayar are about to come to an end.In an article published by Malaysian daily Berita Harian, it was reported that vehicle owners who give their vehicles away to a third party to service their loans without approval will be fined or jailed.In a reply to a question posed by a member of parliament, the Malaysian Home Ministry has clarified that such practices is against the Hire-Purchase Act of 1967. In a statement issued to the House of Commons (Dewan Rakyat), it was stated that “Action can be taken against owners who pawn their vehicles or ‘sambung bayar’ to third parties without the bank’s knowledge and approval.”The law is explicit – Section 38 of the Hire Purchase Act states that an owner who sells or leases their vehicle while the hire purchase agreement is in force can be sentenced to a RM3,000 fine or three years jail, or both, if found guilty.So if you are currently riding or driving a vehicle that belongs to someone else while you pay the monthly installments or if you have let someone else service your loan for you, it will be a good time to return the vehicle as more stringent enforcement is on the way.Read the original article by Berita Harian. –Ads–
