In this paper we propose an approach to lightweight acquisition, sharing and annotation of experience-based corpora via mobile devices. Corpora acquisition is the crucial and often costly process in speech and language science and engineering. To address this problem, we have built a system for creating a location based corpora annotated with multimedia tags (e.g. text, speech, image) generated...

NameNode * Metadata: Information about file + plus set of block IDs + location of all replicas of all blocks * Treats each FS operation as transaction Maintains all information in memory Logs to EditLog file (Possibly outdated) backup copy stored on disk. Can bring this copy up to date by replaying entries in EditLog * Periodic checkpoint: Apply transactions in editlog to disk image Delete old ...

The rate at which CO2 is released from woody debris post-clearcut affects the long term carbon consequences of such disturbances. Changes in microclimate post-clearcut may alter the rate of woody debris decomposition from that in a mature forest. However, very few studies have explored post-disturbance rates of woody debris respiration and the possible influence of an altered microclimate, and ...

~ Riparian vegetation increases stream channel complexity and directly contributes to aquatic habitat through inputs of logs and branches. In turn, the provision of complex habitat has a major influence on aquatic biodiversity. ~ Logs and branches can enhance stream stability, regulate sediment transport and exert significant control on channel complexity in bedrock rivers and channel geomorpho...

A potential problem for persisting large volume of streaming logs with conventional relational databases is that loading large volume of data logs produced at high rates is not fast enough due to the strong consistency model and high cost of indexing. As a possible alternative, state-of-the-art NoSQL data stores that sacrifice transactional consistency to achieve higher performance and scalabil...

-Authentication is the process of identifying an individual, usually based on username and password. Authentication merely ensures that the individual is who he or she claims to be. This forestalls the activities against confidentiality and integrity. Shoulder surfing is the main problem of graphical passwords. To overcome the problem of shoulder surfing we introduced a novel Scheme. This schem...

The ImageCLEF Photo Retrieval Task 2009 focused on image retrieval and diversity. A new collection was utilised in this task consisting of approximately half a million images with English annotations. Queries were based on analysing search query logs and two different types were released: one containing information about image clusters; the other without. A total of 19 participants submitted 84...

estimation of reservoir water saturation (sw) is one of the main tasks in well logging. many empirical equations are available, which are, more or less, based on archie equation. the present study is an application of radial basis function neural network (rbfnn) modeling for estimation of water saturation responses in a carbonate reservoir. four conventional petrophysical logs (pls) including d...

Image logs of 13 wells in the Rag Sefid Anticline show two systems of fractures developed under two deformation phase in the Dezful Embayment. This deformation phases are folding resulted from Zagros NE contraction and reactivation of the basement fault rotated the fold axial trace within the Hendijan-Izeh fault zone. Folding phase comprises four sets of fractures, which include axial and cross...

The formal concept of a workflow to single-particle analysis of cryo-electron microscopy (cryo-EM) images in the RELION program is described. In this approach, the structure-determination process is considered as a graph, where intermediate results in the form of images or metadata are the vertices, and different functionalities of the program are the edges. The new implementation automatically...
