Sir, I am a M.tech student of Computer Science and Engineering Department ,Indian Institute of technology, Kharagpur(India). I have to do a project in trusted computing field. I went through LLVM Project site. and I want to work in some project of LLVM. Can u suggest me some project which is somehow related to trusted computing and i can work on that ? In hope of your reply, Amit Suthar

Hello Sir, I am a third-year student at the Department of mathematics at IIT Kharagpur. I have good experience in Information Retrieval and Machine Learning. I have read many chapters of the book Introduction to Information Retrieval. Recently I am doing a project on tagging a question on a Q&A Forum using ranking the tags and probabilistic inference. I also have software development

Hello, I'm using fArma package to estimate the value of Hurst exponent using R/S method. However, for a certain set of data I get H ~ 1.8. How do I interpret this? Following are the output that I get for this set: > mean(data[,2]) [1] 400.5433 > sd(data[,2]) [1] 1139.786 > > rsFit(data[,2], levels = 64) Title: Hurst Exponent from R/S Method Call: rsFit(x = data[, 2], levels

I am new in R. Can anyone tell : 1. how we can write our own functions in R ? 2. how we can save those functions and recall to use them? 3. what extensions are used for saving a file? -- Siddharth Arun, 4th Year Undergraduate student Industrial Engineering and Management, IIT Kharagpur [[alternative HTML version deleted]]

I am using AUTO ARIMA for forecasting. But it is not detecting 'seasonality term' of its own for any data. Is there any other method by which we can detect seasonality and its frequency for any data? Is there any method through which seasonality and its frequency can be automatically detected from ACF plot? -- Siddharth Arun, 4th Year Undergraduate student Industrial Engineering and

Hello I am currently working on forecasting hourly electricity prices where I am required to do wavelet transformation. First I need to calculate decomposition coefficients of the wavelet transform, then I need to select wavelet function using multiresolution technique. I would be really grateful if I can find any help in this matter. Thanking You with regards, -- Name : Tarun Trivedi Senior

Hello, I'm an absolute beginner with R. I'm hoping to do some time-series analysis on my data. The data looks like #time value 18 153 20 426 70 7 83 130 84 7 and so on where time could be in seconds or hours or days (not all at the same time). How could I import such a file to R and do some simple stuff (say plot the values)? As per the tutorials on time series, I could use the ts()

Hi All, I have installed rysnc-2.6.3 on my debian linux ( 2.2.20-idepci #1 Sat Apr 20 12:45:19 EST 2002 i686). While configuration it was successful and i installed it without any error. Now, in default installation it should create rsyncd.conf as detault configuration file.. but it has not been created anywhere in system. root@jike:/tmp/temp/rsync-2.6.3# which rsync /usr/local/bin/rsync In

I thought if a daemon is already running on the default port, I thought the additional ones started on the same port will result in an exit with error, but somehow it seems to work just fine. If I kill the first process, the second process seems to take control of the port. As far as I know you can't have two processes binding to the same port, so does that mean the second process is just

Respected Sir/Madam, I have a question regarding calculation of LD50 (Lethal Dose) and IC50 (50% inhibitory concentration) of an antimicrobial experiment. I have used a compound isolated from a plant and observed its effect on the fungus *Fusarium oxysporum* by the food poisoning method. Solutions of the compound at concentrations of 0, 50, 100, 150, 200 and 250µg/ ml were added to

I am using auto.arima() for forecasting.When I am using any in built data such as "AirPassangers" it is capturing seasonality. But, If I am entering data in any other format(in vector form or from an excel sheet) it is not detecting seasonality. Is there any specific format in which it detects seasonality or I am doing some thing wrong? Does data have to be entered in a specific

1. I have a R program in a file say "functions.R". I load the "functions.R" file the R using source("function.R") and then call functionsf1(), f2() etc. which are declared and defined within "function.R" file. I also need to load a couple of R libraries using library() before I can use f1(), f2() etc. My question is can I acheive all this (i.e. calling

Hello, I'm using the fArma package to estimate Hurst exponent by R/S method. I've some measurements in the following format: Call_number Call_duration I'm using the following steps. Am new to R, so it would help if someone could please confirm if my steps are correct. Further, this method seems to give a value H ~= 0.8 (> 0.5). Is the use of R/S method to estimate H OK? >
