Nine-grid algorithm is an image processing algorithm used in screen monitoring software. It divides the screen into nine equally sized grid regions and analyzes and compares the pixel values in each region to achieve precise analysis of the screen image. The analysis of the Nine-grid algorithm in screen monitoring software is as follows: ...

Greedy algorithm is an algorithm based on the greedy approach, which is commonly used to find the globally optimal solution by selecting the locally optimal solution at each step, considering the given constraints. The application of the greedy algorithm in computer monitoring software can include several aspects: File scanning: When...

I want sentiment based category wise dictionary which categories words like fruits, vehicles, conjunctions, articles etc. Dictionary which categorize negative and positive words are available easily but this I could not find out.

Hi, everyone. I am developing an application to simulate signal processing, and I would like to generate a channel that introduces distortion to a signal. I would like to generate the coefficients of the z-transform of the channel in a random fashion, but what is the possible range of values for each coefficient? Would it be the real values from 0...

Hello, Can someone please help me determine the Matlab code that we required in order to produce a Matlab figure of the pattern I have attached. This is a somewhat helical like graph. I have been breaking my head over this and haven't got anywhere useful. Any help would be greatly appreciated. Thanks so much.

#include<stdio.h> #include<time.h> #include<conio.h> #include<assert.h> int main() { clock_t start, stop; int n,i,j,temp,a; scanf("%d",&n);

Dijkstra’s algorithm is a method for solving the single-source shortest path problem on a graph, and can be applied in various fields such as computer networks and transportation. In the context of company monitoring software, Dijkstra’s algorithm can be used to calculate the shortest path between different nodes in the monitoring system, allowing...

Can someone please help me with this question. I'm unsure as how to get the function to error when N<2... i really need help!!!

i have a waveform: y2(x)= sin(x*1.2)+sin(x*1.8 ) the first 6 nodes, meaning the parts of the wave where y2=0 come up on my graph at around x = 2.094 4.189 5.236 6.283 8.377

write an alogrithm to find out average milage per liter?

hi, i am research student, my research topic is about to compare the crawling process for Bfs and Dfs, have anyone willing to share their sample crawler code? Thank You!

How many random people do you have to select before you find three people who share the same birthday? That is, all three people were born on the same day in the same month, but not necessarily in the same year.the month and day should appear but i don't know how to do it.. can you help me?

Does anybody give me suggestions in implementing an algorithm using a programming language such as C#. For example, lets say; I had a stream of data continuously coming to me. I want to filter the data based on certain conditions such as "if new data is lessthan 10", discard the new data. I can implement the same by 'C# generic collection',...

Hi Folks, I am writing a simple parser to parse SPICE code ( Spice is a transistor level simulator ). The spice code looks like this - ======================== R10 2 3 0.5e-3 C11 4 6 0.2e-6 L13 4 4 0.1e-9 ========================= As you can see each line has 4 items - a character string followed by an integer then another integer and...

Finding 5 missing numbers from array of 1 million numbers ( array can be any order but there is no repeated numbers )

which sort is best for sorting numbers upto 10^6 and each number is upto 10^6 large?

I recently discovered the goodness of system modelling by means of Formal Concept Analysis. I think it is a great technique which I want to research deeper. I have a concern though and I would like to hear your comments about it. Once I create my tables with the different concepts for my formal objects and attributes, I feed those tables in...

I need to convert the size of a Mobile phone pixels into mm the screen size is 800x480 pixels

Hello everyone. I am new here and I am sorry if a topic like this has already been posted, but I am taking a graduate level course in Design and Analysis of Algorithms this semester and I pulled a real hard ass of a professor, the kind you pray you don’t get for a class like Algorithms but which if you are unlucky enough to get it will be in just...

what algorithm is used for NDIS driver in c language

Hello, im currently working on a small project to create a program that allows a user to input text, select an encryption alogrithm and cipher his text. I found this DES class and was wondering would be to comment on it in order for to understand what is going on class DES { public string DES_Encrypt(string originalString, string...

could you please suggest me books(or e-books) for "intro to algorithms "!!!! right now i'm learning it through googling,it is very tedious job .A book starting from the basic level(step by step explanation) .

hi there, i need to know how to merge over segmented cells that occur due to watershed transformation.can anybody help me with some functions that can do this in matlab or some code that can rectify this over segmentation problem.

I'm having two almost the same images. Only one has an extra transparent blueish circle over a part of the image, and the original not. How do I get the RGBA or ARGB of this circle (thus not the RGB)? I guess the original image should be subtracted form the modified image and from the result I want the RGB + alpha. If code is required I...
