    Abstract. The main aim of this research is to improve communication between student and teacher by using the developing mobile information technologies. Implementing such technologies in education may help to develop learning environments to share the knowledge among students and increase their motivation to possible highest level. Based on mobile equipments used in daily life an online student announcement system has been developed which aims to provide sharing of documents and communication ways between students and teachers.

    Abstract-In this paper, simple autonomous chaotic circuits coupled by resistors are investigated. By carrying out computer calculations and circuit experiments, irregular self-switching phenomenon of three spatial patterns characterized by the phase states of quasi-synchronization of chaos can be observed from only four simple chaotic circuits. This is the same phenomenon as chaotic wandering of spatial patterns observed very often from systems with a large number of degrees of freedom. Namely, one of spatial-temporal chaos observed from systems of large size can be also generated in the proposed system consisting of only four chaotic circuits. A six subcircuits case and a coupled chaotic circuits networks are also studied, and such systems are confirmed to produce more complicated spatio-temporal phenomena.

  • ISIS Timer Design

    A design about 8051 (running at 12MHz) based system with 3 7-Seg displays and two buttons to implement the following functions.  1. When press the + button, the display C = A+B.  2. When press the button, the display C = A - B.  “A” and “B” are 8-bit inputs when “C” is 9-bit output.

  • java入門編程合集

    題目:古典問題:有一對兔子,從出生后第3個月起每個月都生一對兔子,小兔子長到第三個月后每個月又生一對兔子,假如兔子都不死,問每個月的兔子總數(shù)為多少?    //這是一個菲波拉契數(shù)列問題 public class lianxi01 { public static void main(String[] args) { System.out.println("第1個月的兔子對數(shù):    1"); System.out.println("第2個月的兔子對數(shù):    1"); int f1 = 1, f2 = 1, f, M=24;      for(int i=3; i<=M; i++) {       f = f2;       f2 = f1 + f2;       f1 = f;       System.out.println("第" + i +"個月的兔子對數(shù): "+f2);          } } } 【程序2】    題目:判斷101-200之間有多少個素數(shù),并輸出所有素數(shù)。 程序分析:判斷素數(shù)的方法:用一個數(shù)分別去除2到sqrt(這個數(shù)),如果能被整除, 則表明此數(shù)不是素數(shù),反之是素數(shù)。    public class lianxi02 { public static void main(String[] args) {     int count = 0;     for(int i=101; i<200; i+=2) {      boolean b = false;      for(int j=2; j<=Math.sqrt(i); j++)      {         if(i % j == 0) { b = false; break; }          else           { b = true; }      }         if(b == true) {count ++;System.out.println(i );}                                   }     System.out.println( "素數(shù)個數(shù)是: " + count); } } 【程序3】    題目:打印出所有的 "水仙花數(shù) ",所謂 "水仙花數(shù) "是指一個三位數(shù),其各位數(shù)字立方和等于該數(shù)本身。例如:153是一個 "水仙花數(shù) ",因為153=1的三次方+5的三次方+3的三次方。 public class lianxi03 { public static void main(String[] args) {      int b1, b2, b3;
