Early practical experience, based upon empirical observations strongly indicates that using classes as the basis for eeort estimation, can help to achieve DeMarco's holy grail. In providing evidence for this claim this position paper will describe (i) empirical size observations; (ii) estimations processes, based upon these observations ; and (iii) initial experiences using these processes. Thi...

This paper develops a series of performance models for predicting performance of applications on virtualized systems. It introduces the main ideas of performance modeling and presents a complete case study of an application running on Linux that is migrated to a virtualized environment consisting of Linux and Xen. The paper describes the models, the process of obtaining measurements for the mod...

The paper presents the basic requirements that must cover distance education processes (“e-learning”) in universities. We show the concepts of instruction design, an adaptive learning model for evaluating necessities, accreditation, and quality proposal. The experience indicates that to obtain good results we should evaluate the differences between the criteria of the professor and the criteria...

Understanding secondary structures of RNAs helps to determine their chemical and biological properties. Only a small number of RNA structures have been determined currently since such structure determination experiments are timeconsuming and expensive. As a result, scientists start to rely on RNA secondary structure prediction. Unlike protein structure prediction, predicting RNA secondary struc...

In this paper we present a probabilistic approach to analysis and prediction of protein structure. We argue that this approach provides a exible and convenient mechanism to perform general scienti c data analysis in molecular biology. We apply our approach to an important problem in molecular biology|predicting the secondary structure of proteins|and obtain experimental results comparable to se...
