高的工作電壓高達100V N雙N溝道MOSFET同步驅動 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.

Tug of War(A tug of war is to be arranged at the local office picnic. For the tug of war, the picnickers must be divided into two teams. Each person must be on one team or the other the number of people on the two teams must not differ by more than 1 the total weight of the people on each team should be as nearly equal as possible. The first line of input contains n the number of people at the picnic. n lines follow. The first line gives the weight of person 1 the second the weight of person 2 and so on. Each weight is an integer between 1 and 450. There are at most 100 people at the picnic. Your output will be a single line containing 2 numbers: the total weight of the people on one team, and the total weight of the people on the other team. If these numbers differ, give the lesser first. )

．數據結構 假設有M個進程N類資源，則有如下數據結構： MAX[M*N] M個進程對N類資源的最大需求量 AVAILABLE[N] 系統可用資源數 ALLOCATION[M*N] M個進程已經得到N類資源的資源量 NEED[M*N] M個進程還需要N類資源的資源量 2．銀行家算法 設進程I提出請求Request[N]，則銀行家算法按如下規則進行判斷。 (1)如果Request[N]<=NEED[I，N]，則轉(2)；否則，出錯。 (2)如果Request[N]<=AVAILABLE，則轉(3)；否則，出錯。 (3)系統試探分配資源，修改相關數據： AVAILABLE=AVAILABLE-REQUEST ALLOCATION=ALLOCATION+REQUEST NEED=NEED-REQUEST (4)系統執行安全性檢查，如安全，則分配成立；否則試探險性分配作廢，系統恢復原狀，進程等待。 3．安全性檢查 (1)設置兩個工作向量WORK=AVAILABLE；FINISH[M]=FALSE (2)從進程集合中找到一個滿足下述條件的進程， FINISH[i]=FALSE NEED<=WORK 如找到，執行(3)；否則，執行(4) (3)設進程獲得資源，可順利執行，直至完成，從而釋放資源。 WORK=WORK+ALLOCATION FINISH=TRUE GO TO 2 (4)如所有的進程Finish[M]=true，則表示安全；否則系統不安全。

Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution ％ ％ compute the forward/backward Campbell/specgtrogram ％ ％ INPUT: ％ y (n x 2) each column is measured from a different sensor ％ /////// ％ __ ％ |s1| y(:,1) ％ |__| ％ __ ％ / \ ________|/ ％ | | | s2 |/ y(:,2) ％ \____/ --------|/ ％ ％ Fs Sampling frequnecy ％ ％ OUTPUT: ％ B spectrogram/Campbel diagram ％ x x-axis coordinate vector (time or Speed) ％ y y-axis coordinate vector (frequency [Hz])
