Urbanization affects streams by modifying hydrology, increasing pollution and disrupting in-stream and riparian conditions, leading to negative responses by biotic communities. Given the global trend of increasing urbanization, improved understanding of its direct and indirect effects at multiple scales is needed to assist management. The theory of stream ecology suggests that the riverscape an...

We present an approach to learning complex dependencies among multiple streams of time-series data incrementally. Given a set of input streams that contain categorical values that change over time, we characterize recurring structure with a set of dependency rules that can be used to predict stream values in the future. These rules are general in the sense of ignoring noisy values in streams.

With the advances in audio encoding standards and wireless access networks, voice over IP (VoIP) is becoming quite popular. However, real-time voice data over lossy networks (such as WLAN and UMTS), still posses several challenging problems because of the adverse effects caused by complex network dynamics. One approach to provide QoS for VoIP applications over the wireless networks is to use mu...

We consider the read/write streams model, an extension of the standard data stream model in which an algorithm can create and manipulate multiple read/write streams in addition to its input data stream. Like the data stream model, the most important parameter for this model is the amount of internal memory used by such an algorithm. The other key parameters are the number of streams the algorit...

the aim of this study was to empirically investigate the effect of death-awareness on state mindfulness and state integrative self-knowledge. for existentialists, confrontation with the fact of one’s personal death and tolerance of its inevitable anxiety is the most fundamental conflict of human beings. if such confrontation occurs, it leads to enhancement of one’s self-awareness. empirical tes...

Data streams have emerged as an important research area in recent years due to its ubiquitous presence in various application domains including stock market analysis in finance. Therefore, it has become increasingly demanding to develop efficient techniques to discover useful patterns from such data streams. Among many issues, analyzing the correlation between two data streams is an important t...

Video streaming technique is widely used in the Internet with the development of access networks. Although some techniques such as Forward Error Correction or Content Distribution Network are effective for video streaming services, they are not sufficient in the case that streams are suffered from heavy packet loss. For this problem, we propose a novel error correction method called “ECLIPSE: E...

We present a general theory for the computation of stream transformers of the form F : (R! B)! (T ! A), where time T and R, and data A and B, are discrete or continuous. We show how methods for representing topological algebras by algebraic domains can be applied to transformations of continuous streams. A stream transformer is continuous in the compact-open topology on continuous streams if an...
