At last, an adjustable parameter is employed to compensate the degrada- tions of BER at low and moderate SNR regions. Case studies indicate that the improvements of BER for turbo codes with short frame size are significant at a wide range of SNR展开更多

Accounting and Auditing Organization for Islamic Financial Institutions （AAOIFI）, as an international standard-setting organization for Islamic finance, raised an issue that 85% issuances of Musharakah and Mudharabah sukuk have breached the shariah rulings and do not comply with Islamic principles （AAOIFI, 2002）. Consequently, the performance of equity-based sukuk in Malaysia was affected. This study used a secondary data for size of issuances which are gathered from Bank Negara Malaysia （BNM）＇s Bond Info website and Securities Commission （SC） website. The performance of equity-based sukuk, either Musharakah or Mudarabah, is robust in the study year period of 2000-2012 as regards their sizes of issuances.展开更多

The control combines a model-free fuzzy control, a fuzzy sliding-mode control and a model-based fuzzy control. The model-free fuzzy controller designed for the upswing ensures that the energy of the acrobot increases with each swing. Then the fuzzy sliding-mode controller is employed to control the movement that the acrobot enters the balance area from the swing-up area. The model-based fuzzy controller, which is based on a Takagi-Sugeno fuzzy model, is used to balance the acrobot. The stability of the fuzzy control system for balance control is guaranteed by a common symmetric positive matrix, which satisfies linear matrix inequalities.展开更多
