Hi,

I want to show some letters in Bibliography as capital. For example:

@misc{libsvm,  
abstract = {LIBSVM is an implbmentation of Support vector machine (SVM).},  
author = {Chang, Chih-Chung},  
howpublished = {\url{http://www.csie.ntu.edu.tw/~cjlin/libsvm/}},  
keywords = {svm},  
posted-at = {2010-04-08 00:05:04},  
priority = {2},  
title = {LIBSVM.},  
url = "http://www.csie.ntu.edu.tw/~cjlin/libsvm/",  
year = {2008}  
}  

But "LIBSVM" is not shown as it is:

[3] Chih-Chung Chang. Libsvm. http://www.csie.ntu.edu.tw/ ~cjlin/libsvm/, 2008.

How can I make the letters capital? Thanks and regards!
