In China, 260 million people migrate to cities to realize their urban dreams. Despite that these migrants play an important role in the rapid urbanization process, many of them fail to settle down and eventually leave the city. The integration process of migrants thus raises an important issue for scholars and policymakers. In this paper, we use Shanghai as an example to investigate migrants’ b...

Time-domain eoders use long-term predietors to exploit the quasiperiodie strueture of voiced speech. However, one major drawbaek with classical predictors is the restriction of the delay to integer values, reducing the performance especially when the pitch period is short. This paper presents an extension of the prediction technique to encompass non-integer delays enabling more aeeurate represe...

This study utilized energy simulation in support of a forensic pathology time of death analysis for a corpse discovered in a single family residence two years prior to the study. In order to produce an accurate estimate of the interior temperature profile at the time of death, a thermal model was constructed using EnergyPlus and calibrated using environmental monitoring data from the site. The ...

The prediction of protein structure is an important problem in molecular biology. It is also a diicult problem since the available data are incomplete and uncertain. This paper describes models for the prediction of a particular level of protein structure, known as the topology, which handle uncertainty in a qualitative fashion.

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...
