The combinatorial core of the OVSF code assignment problem
that arises in UMTS is to assign some nodes of a complete binary
tree of height h (the code tree) to n simultaneous connections, such that
no two assigned nodes (codes) are on the same root-to-leaf path. Each
connection requires a code on a specified level. The code can change over
time as long as it is still on the same level. We consider the one-step code
assignment problem: Given an assignment, move the minimum number of
codes to serve a new request. Minn and Siu proposed the so-called DCAalgorithm
to solve the problem optimally. We show that DCA does not
always return an optimal solution, and that the problem is NP-hard.
We give an exact nO(h)-time algorithm, and a polynomial time greedy
algorithm that achieves approximation ratio Θ(h). Finally, we consider
the online code assignment problem for which we derive several results
Instead of finding the longest common
subsequence, let us try to determine the
length of the LCS.
Then tracking back to find the LCS.
Consider a1a2…am and b1b2…bn.
Case 1: am=bn. The LCS must contain am,
we have to find the LCS of a1a2…am-1 and
b1b2…bn-1.
Case 2: am≠bn. Wehave to find the LCS of
a1a2…am-1 and b1b2…bn, and a1a2…am and
b b b
b1b2…bn-1
Let A = a1 a2 … am and B = b1 b2 … bn
Let Li j denote the length of the longest i,g g
common subsequence of a1 a2 … ai and b1 b2
… bj.
Li,j = Li-1,j-1 + 1 if ai=bj
max{ L L } a≠b i-1,j, i,j-1 if ai≠j
L0,0 = L0,j = Li,0 = 0 for 1≤i≤m, 1≤j≤n.
Reads/writes text as a character stream, buffering characters so as to provide for the efficient reading/writing of characters, arrays, and lines.
The buffer size may be specified, or the default size may be used. The default is large enough for most purposes.
In general, each read request made of a Reader causes a corresponding read request to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders.
1. This BSP can support 2443EVT0 board.
If you want to use EVT0 BSP, set followings.
In smdk2443\smdk2443.bat file
set BSP_EVT1=1
-> set BSP_EVT1=
In smdk2443\src\inc\bsp_cfg.h file
#define EVT1
-> #define EVT0
2. Default system tick mode is changed. The value is fixed tick.
Fixed tick means that tick interrupt is occurred every 1ms.
Variable tick means that timer interrupt period is changed when power mode is in idle.
For changing to variable tick
In smdk2443\src\inc\bsp_cfg.h file
#define FIXEDTICK
-> #define VARTICK
In smdk2443\src\Common\Timer\Sources file
SOURCES= timer_fixedtick.c watchdog.c
->
SOURCES= timer_vartick.c watchdog.c
I was trying to develope a programme to make a slide show of all the pictures of a folder using vb.net. I have spent lot of time in net for searching this but all in vain, I didn t get a simple programme to solve the same and lastly I gave myself a try for the same and developed the code, I have used there a folderbrowserdialogue and a timer with a picture box control and in coding I have used IO name spaces to get the pathe and folder info here is the code.
Enjoy

This is a Flex UIComponent that can be used 謀n a FLEX 3 mxml application as component written in action script 3.0, provides you to create items that cab be filled from an XML or Query ResultSet or etc. and is viewed in a container that can preview images and additional info like a store item and can be added to shopp謀ng chart , and also can be deleted from that shopp謀ng chart
This is a desktop application written in java which sends email using gmail smtp. You do not need to go to the browser to send email. If you do not have a gmail account that is ok too because you can send email by a default account and of course by your own account. You need jdk 1.6 or higher to run it.
