Alan Hovhaness (1911年3月8日－2000年6月21日），亞美尼亞-蘇格蘭裔美國作曲家，20世紀最多產的古典音樂作曲家之一。
Regarding your fax transmission dated September 28, 2005, your colleague is set to arrive at the Taoyuan International Airport in Taiwan.
According to our government’s tax system, a technical service fee is subject to a 20% tax levy. Your company must prepare an invoice that includes the amount of money received by ABC Institute (EU____) and taxes(EU___). Our organization will cover the transportation fee (save your receipt) and counterfoil of your return ticket. Therefore, you must copy the receipt and the counterfoil for us to pay for the transportation fee. What is the best method of reimbursing your expenses? We look forward to hearing from you.

工程計劃建構 Direct-sequence code-division multiple-access (DS-CDMA) has been adopted in 3rd generation (3G) cellular systems owing to its higher data rate, enhanced quality, and larger capacity than the modulation schemes of available systems. Mobile stations must acquire cell-specific spreading codes or code phases before receiving system information from cell sites in DS-CDMA systems. Code acquisition (CA) procedures inevitably require enormous operations to correlate and sum up each chip of the spreading codes. Application-specific hardware or digital signal processors (DSPs) can be used to implement CA procedures. Additionally, software defined radio (SDR) concept has received increasing attention. More than one system specification will be incorporated into user equipment in the near future. How to implement various CA procedures efficiently is thus of priority concern. 工程計劃問題 Implementing CA procedures by software on DSP is feasible for SDR-based user equipment – regardless of cost and power consumption. Although state-of-the-art DSPs can provide more than 1 giga-instruction-per-second (GIPS), most CA procedures are still implemented using application-specific hardware because intense data dependency of CA operations minimizes the benefits of pipelining and parallelizing of arithmetic architecture in DSPs. Various spreading codes necessitate long design progresses of application-specific hardware, respectively. Additionally, individual CA modules can significantly elevate hardware costs. 工程計劃問題的量化 For instance, DSPs can provide around 1 to 2 GIPS using pipelining and parallelizing schemes. These calculating capabilities will be degraded to 100 to 200 MIPS only due to data dependency of CA procedures. Unfortunately, more than 1 giga-operation-per-second (GOPS) is required in CA procedures. These CA operations normally require more than one instruction. Application-specific hardware thus becomes the only viable means of implementing various CA procedures on the same platform. 工程計劃問題的中心 The inability to develop a generic CA architecture makes it impossible to simplify the design of application-specific hardware and control hardware costs. 工程計劃需求 Therefore, a generic CA architecture must be designed to execute various CA procedures on the same platform.
