Business Process Management (BPM) has been an important research field for decades. Latest technological advances have increased the transparency that can be created over processes. Although associated to various advantages, organizations struggle to identify processes for which investments in visibility-creating technologies are profitable. Existing research has largely investigated the outcom...

1. Introduction. In the study of evolution equations that describe the dynamics of natural and man-made systems, it is always useful to determine the way in which information is propagated by the said equations. In other words, the manner in which different scales present in the solution of an evolution equation travel and decay through space and time. The ideal tool to determine the propagatio...

The mechanisms of information transmission are investigated in a lattice of coupled continuous maps, by analyzing the propagation of both finite and infinitesimal disturbances. Two distinct regimes are detected: in the former case, both classes of perturbations spread with the same velocity; in the latter case, finite perturbations propagate faster than infinitesimal ones. The transition betwee...

Rumor propagation has been well studied in the past decade, the main concentration is focused on the dynamic behavior analysis of model system, but little attention is paid to the limited information exchange among nodes in the network topology. In this paper, we numerically investigate the limited information transmission influence the rumor spreading. The information packet transmission quant...

Vehicular Ad-hoc Networks (VANETS) have recently received great attention as a tool to disseminate information among vehicles with the dual purpose of increasing road safety and comfort in driving. Most of the messages that vehicles exchange are characterized by a finite lifetime period, after which, their level of usefulness is greatly reduced. Thus, an important problem in VANETS is to find e...

The IR group participated in the crosslanguage retrieval task (CLIR) at the sixth NTCIR workshop (NTCIR 6). In this paper, we describe our approach on Chinese Single Language Information Retrieval (SLIR) task and English-Chinese Bilingual CLIR task (BLIR). We use both bi-grams and single Chinese characters as index units and use OKAPI BM25 as retrieval model. The initial retrieved documents are...

The topic of this thesis is Opportunistic Networks (opnets), a type of mobile ad hoc network in which data are propagated by the movement of the network devices and by short-range wireless transmissions. This allows data to spread to many devices across large distances without the use of any infrastructure or powerful hardware. Opnet technology is in its fairly early stages of development and h...

Music is beautiful, and music communication is a dissemination of beauty, which could make more people enjoy that kind of beauty. MicroBlogging, as a new media, is more and more popular for users, especially for younger people. The timeliness of Microblogging makes it more convenient for music communication on the Internet. In this paper, we study how a musical event is propagated according to ...
