Human-based electronic services (people services) provide a powerful way of outsourcing tasks to a large crowd of remote workers over the Internet. Because of the limited control over the workforce in a potentially globally distributed environment, efficient quality management mechanisms are a prerequisite for successful implementation of the people service concept in a business context. Resear...

As computers become more and more networked, and more bandwidth will be consumed by network flow because customers will be connected through networks which will transfer files and data, such as video files (MPEGn, AVI, WMV, etc.) to be watched at a customer?s computer. The main purpose of this paper is to optimize large scale network handling capabilities for large system inventories and to imp...

Multisensor data fusion is a powerful solution for solving difficult pattern recognition problems such as the classification of bioelectrical signals. It is the process of combining information from different sensors to provide a more stable and more robust classification decisions. We combine here data fusion with multiresolution analysis based on the wavelet packet transform (WPT) in order to...

Palmprint is one of the most useful physiological biometrics that can be used as a powerful means in personal recognition systems. The major features of the palmprints are palm lines, wrinkles and ridges, and many approaches use them in different ways towards solving the palmprint recognition problem. Here we proposed to use a set of statistical and waveletbased features; statistical to capture...

OBJECTIVE Increasing evidence suggest that neuronal damage is an early and diffuse feature of Multiple Sclerosis (MS) pathology. Analysis of the optic pathway may help to clarify the mechanisms involved in grey matter damage in MS. Purpose of our study was to investigate the relationship between inflammation and neurodegeneration and to achieve evidence of trans-synaptic degeneration in the opt...

Crowdsourcing is an effective tool for human-powered computation on many tasks challenging for computers. In this paper, we provide finite-sample exponential bounds on the error rate (in probability and in expectation) of hyperplane binary labeling rules under the Dawid-Skene crowdsourcing model. The bounds can be applied to analyze many common prediction methods, including the majority voting ...

watermelon mosaic virus is the most prevalent potyvirus infecting cucurbits in iran. in order to determine the distribution and frequency of the virus, 326 watermelon, melon, cucumber, winter and summer squash samples were collected from 22 villages around urmia during summer 2010 and tested by das-elisa with a polyclonal antibody. ninety four samples were detected as infected by elisa. to dete...

Abstract Coat protein (CP) is required for potyviruses to move and establish a systemic infection in plants. π-stackings formed by aromatic residues play critical roles maintaining stability functions. As we know, many located the core region of potyvirus CPs are conserved. However, their remain largely unknown. Here, through analysis three-dimensional model tobacco vein banding mosaic virus (T...
