Web-based logs contain potentially useful data with which designers can assess the usability and effectiveness of their choices. Most guides to World Wide Web (Web) design derived from artistic or usability principles feature no empirical validation, while empirical studies of Web use typically rely on observer ratings. Several sources of unobtrusive usage data are available to Web designers, i...

Application console logs are a ubiquitous tool for diagnosing system failures and anomalies. While several techniques exist to interpret logs, describing and assessing log quality remains relatively unexplored. In this paper, we describe an abstract graphical representation of console logs called the identifier graph and a visualization based on this representation. Our representation breaks lo...

The Groningen gas field in the Netherlands is an ideal test bed for in-situ reservoir monitoring techniques because of availability both active and passive in-reservoir seismic data. In this study, we use deconvolution interferometry to estimate reflection transmission response using borehole data within at ∼3-km depth separate up- downgoing P- S-wave fields by f-k filtering. We validate result...

4-(acetoacetamido) arsanilic acid (ii), which was then condensed with aryl aldehydes. the resulting product on reaction with hydrazine hydrate and hydroxyl amine hydrochloride yielded pyrazolines (iv) and isoxazolines (v), respectively. the antimicrobial activity of compounds against a number of microorganisms was evaluated. some of these compounds showed significant antimicrobial activity

AVO studies have enjoyed a mixed success rate in predicting the existence of hydrocarbons in sediments. Sometimes AVO predictions are accurate, but other times they can be quite wrong. It seems likely that the success rate might increase if more sophisticated AVO methods could be employed such as full wave inversion. In fact elastic wave equation inversion has been applied to seismic data with ...

The objective of this work was to study maritime pine (Pinus pinaster Ait.) wood characteristics and their impact on the sawing yield using virtual stem models and sawing simulation procedures. In the first part of the work, a characterisation of maritime pine as raw material for the wood industry was performed. The stem shape, distribution of knots, and heartwood/sapwood contents were studied....
