The main purpose of this project is to add a new scheduling algorithm to GeekOS and to implement a simple synchronization primitive (semaphore). As you might have already noticed, GeekOS uses a simple priority based preemptive Round Robin algorithm. In this project, you will change this to a multilevel feedback scheduling. In addition, you will provide user programs with semaphores, a means to check the system s current time and a mechanism for passing command-line arguments

Scotia Airlines is a new budget airline operating between Glasgow Airport and the Western Isles. It operates two 24-seater light passenger aircraft and requires a flight booking system. Because Scotia offers low cost air travel, there is a need to treat each flight as single cost centre and to be able to ascertain, at any moment, the amount of the cash taken for that flight. Reservations and bookings cannot be made until the flight details have been finalised (flight number, departure and arrival airports). A seat on a flight is considered booked when payment as been received for it. When a reservation is confirmed (changed to booked), the passenger name is checked against the original reservation. A flight can be in any of the following states: Available for bookings Checking in Boarding Closed

Just what is a regular expression, anyway? Take the tutorial to get the long answer. The short answer is that a regular expression is a compact way of describing complex patterns in texts. You can use them to search for patterns and, once found, to modify the patterns in complex ways. You can also use them to launch programmatic actions that depend on patterns. A tongue-in-cheek comment by programmers is worth thinking about: "Sometimes you have a programming problem and it seems like the best solution is to use regular expressions now you have two problems." Regular expressions are amazingly powerful and deeply expressive. That is the very reason writing them is just as error-prone as writing any other complex programming code. It is always better to solve a genuinely simple problem in a simple way when you go beyond simple, think about regular expressions. Tutorial: Using regular expressions

As a consequence, more exact models of devices can be retained for analysis rather than the approximate models commonly introduced for the sake of computational simplicity. A computer icon appears in the margin with each introduction of MATLAB analysis.

編程題（15_01.c） 結構 struct student { long num char name[20] int score struct student *next } 鏈表練習： (1).編寫函數struct student * creat(int n),創建一個按學號升序排列的新鏈表,每個鏈表中的結點中 的學號、成績由鍵盤輸入，一共n個節點。 (2).編寫函數void print(struct student *head),輸出鏈表，格式每行一個結點，包括學號，姓名,分數。 (3).編寫函數struct student * merge(struct student *a,struct student *b), 將已知的a,b兩個鏈表 按學號升序合并，若學號相同則保留成績高的結點。 (4).編寫函數struct student * del(struct student *a,struct student *b),從a鏈表中刪除b鏈表中有 相同學號的那些結點。 (5).編寫main函數，調用函數creat建立2個鏈表a,b,用print輸出倆個鏈表；調用函數merge升序合并2個 鏈表，并輸出結果；調用函數del實現a-b,并輸出結果。 a: 20304,xxxx,75, 20311,yyyy,89 20303,zzzz,62 20307,aaaa,87 20320,bbbb,79 b： 20302,dddd,65 20301,cccc,99 20311,yyyy,87 20323,kkkk,88 20307,aaaa,92 20322,pppp,83
