in order to evaluate times and rate applications of zinc fertilizer on quantity and quality of faba bean, an experiment was carried out to form factorial in randomized of complete block design with four replications at farm research of gonbad kavous university during 2009 – 2010. two times of application were including before flowering and beginning of pod setting and five rates of application ...

Red beds, conglomerates and salt were considered azoic and problematic rocks, but Paleopalynology and Inorganic Geochemistry proved to be useful for placing them in time and space. In the early last century, in Mexican NE region, only three Mesozoic red bed units were differentiated, dated as Late Triassic to Late Jurassic. It was important tratigraphically to place them properly as they were c...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...

In this work, the problem of detecting and tracking targets with synthetic aperture radars is considered. A novel approach in which prior knowledge on target motion is assumed to be known for small patches within the field of view. Probability densities are derived as priors on the moving target signature within backprojected SAR images, based on the work of Jao. Furthermore, detection and trac...

Track-before-detect methods operate directly upon raw sensor signals without a separate, explicit detection stage. An efficient implementation of a Bayesian track-before-detect particle filter is described for tracking of a single target in a sequence of images. The filter provides a sample based approximation to the distribution of the target state directly from pixel array data. The filter al...

Consider an asynchronous system consisting of processes that communicate via message-passing.The processes communicate over a potentially incomplete communication network consisting of reli-able bidirectional communication channels. Thus, not every pair of processes is necessarily able tocommunicate with each other directly.The goal of the algorithms discussed in this paper ...

Context-consistency checking is challenging in the dynamic and uncertain ubiquitous computing environments. This is because contexts are often noisy owing to unreliable sensing data streams, inaccurate data measurement, fragile connectivity and resource constraints. One of the state-of-the-art efforts is CEDA, which concurrently detects context consistency by exploring the happened-before relat...
