this paper explains offset and develops a strategic approach for the implementation of offset-policy for a buyer country. offset emerges when a country cannot afford to pay cash for non-essential imports, and cannot get cash for many of its products. offset arrangements are most frequently found in the defense-related sector. however, recently, it refers to a range of industrial and commercial ...
This paper explains offset and develops a strategic approach for the implementation of offset-policy for a buyer country. Offset emerges when a country cannot afford to pay cash for non-essential imports, and cannot get cash for many of its products. Offset arrangements are most frequently found in the defense-related sector. However, recently, it refers to a range of industrial and commercial ...
Despite many advantages of BrushLess DC motor, torque pulsation is one of the most important disadvantages of it. At first, an optimum primary design of BLDC motor is done using PSO algorithm. Then, other parameters for reducing the torque pulsation are considered by finite element method. It is shown that fractional slot structure has many advantages than conventional one. Both cogging and rip...
The effect of Gibberellic Acid (GA3) and Benzyladenine (BA) on Aloe vera was evaluated at pot cultivation conditions. This study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 and BA at 0, 100...
کنترل برداری مستقیم موتورهای القایی با جهت یابی شار استاتور، یکی از انواع روشهای کنترل برداری موتور القایی است که دارای مزایایی نسبت به سایر روشهاست. مهمترین ضعف این روش وجود انتگرال گیر خالص در تخمینگر شار استاتور است. زیرا وجود dc offset در جریان و ولتاژ اندازه گیری شده، باعث ایجاد خطا در شار تخمینی می شود. در این مقاله ابتدا مشکلات ناشی از dc offset در انتگرال گیرهای فوق بیان می شود. برای حل...
one of the limitations of orthogonal frequency division multiplexing (ofdm) in many applications is its sensitivity to frequency shifts, errors normally referred to as carrier frequency offset (cfo). although, this small offset is negligible in conventional single carrier communication systems, it is a severe problem in the ofdm systems. because, the carriers in ofdm are inherently closely spac...
