in regions with deficient or no data, it is necessary to apply indirect methods to estimate the peak flow. regional flood analysis is the most accurate and reliable technique in such cases. one of the regional flood methods for flood analysis in arid and semi arid regions is hybrid technique, which was applied on data of khorasan razavi province watersheds to estimate the peak flow. hybrid meth...

In music performance, vibrato is an important artistic effect, where slight variations in pitch are introduced to add expressiveness and warmth. Automatic vibrato detection and analysis, although well studied for monophonic music, has rarely been explored for polyphonic music, because of the challenge in multi-pitch analysis. We propose a video-based approach for detecting and analyzing vibrato...

The universal principle that an open system can be driven to a state far from equilibrium, or organized, by strong negative entropy flow from its surroundings has been validated in numerous fields from physics and chemistry to the life science. In this paper, entropy flows for a severe storm are calculated via the entropy flow formula using the National Centers for Environmental Prediction/Nati...

The paper uses Data Envelopment Analysis (DEA) to assess the efficiency of the Depertments of the University of Trieste, considering both research and teaching issues. General guidelines for selecting input and output flows are proposed, different DEA models are considered and discussed, and the quantitative outcomes of the evaluation are analyzed.

In this paper, we develop a compiler algorithm for detecting references to stale data in shared-memory multiprocessors. The algorithm consists of two key analysis techniques, stale reference detection and locality preserving analysis. While the stale reference detection finds the memory reference patterns that may violate cache coherence, the locality preserving analysis minimizes the number of...

We present ongoing work on developing an automated integration system for freight flow analysis and planning. To overcome the limitations of current estimation methods for commodity flows, we use reliable secondary sources, such as employment data, and derive estimates in a principled way by means of a computational workflow. When available, we extract the data automatically from online sources...

From 06.04. to 09.04.2010, the Dagstuhl Seminar 10141 Distributed Usage Control was held in Schloss Dagstuhl Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this...

Recently, scientific workflows have emerged as a platform for automating and accelerating data processing and data sharing in scientific communities. Many scientific workflows have been developed for collaborative research projects that involve a number of geographically distributed organizations. Sharing of data and computation across organizations in different administrative domains is essent...

Context-free approaches to static analysis gain precision over classical approaches by perfectly matching returns to call sites— a property that eliminates spurious interprocedural paths. Vardoulakis and Shivers’s recent formulation of CFA2 showed that it is possible (if expensive) to apply context-free methods to higherorder languages and gain the same boost in precision achieved over first-or...
