the present study was designed to investigate the impact of applying fill-in-the-map and construct-a-map techniques on efl learners’ knowledge of tenses. to this end, sixty efl elementary female students, who were selected based on their performance on a standardized teacher-made proficiency test, were randomly assigned into two equal experimental and control groups. in order to be convinced of...

organizations’ success depends on planning. today, this task iscarried out through a multi-stage process such as defining outlook, devisingstrategies, implementation, performance evaluation, and data analysis andplanning for improvement. on one hand, defining and devising goals, and onthe other hand, implementation and performance evaluation have become themain challenges of top managements. fo...

In this paper, we present a video saliency detection method by spatio-temporal sampling and sparse matrix decomposition. In the method, we sample the input video sequence into three planes: X-T slice plane, YT slice plane, and X-Y slice plane. Then, motion saliency map is extracted from the X-T and Y-T slices, and static saliency map is extracted from the X-Y slices by low-rank matrix decomposi...

In this study, a method for hierarchical examination and visualization of GSM data using the Self-Organizing Map (SOM) is described. The data is examined in few phases. At first temporally averaged data is used and then, in each phase some of the data is discarded and the rest is examined in more detail. The SOM is used both in clustering and in visualization. The actual clustering is performed...

In recent years, with the improvement of computer processing power and the development of sophisticated visualisation software, the traditional static views of geological maps, cross-sections, and other analogue representations have been replaced by digital, three dimensional (3D) models. Building these 3D models involves the assembly of many previously isolated and disparate datasets into a si...

We present metrics to evaluate the performance of video object segmentation and tracking methods quantitatively when groundtruth segmentation maps are not available. The proposed metrics are based on the color and motion differences along the boundary of the estimated video object plane and the color histogram differences between the current object plane and its temporal neighbors. These metric...

In this paper we have adopted anchor models to solve a multi-class problem of automatic emotion recognition from children's speech. The likelihood scores of an utterance over the emotion models are normalized using their within-class covariance matrix (WCCN) in order to increase the difference in the characteristic behavior of scores between classes. After normalization, we find that WCCN not o...

The aim of this paper was to verify the capability of ENVISAT/ASAR images in providing soil moisture maps of agricultural areas. SAR images were collected in two sites in Italy (Alessandria and Montespertoli) in 2003 and 2004, along with ground measurements of soil moisture and roughness. The performances of some inversion statistical algorithms (Regression, Bayes, Neural Network, Nelder-Mead) ...

An edge network deployment consists of many (tens to a few hundred) satellite data centers. To optimize enduser perceived performance, a Global Traffic Management (GTM) solution needs to continuously monitor the performance between the users and the data centers, in order to dynamically select the “best” data center for each user. Though widely adopted in practice, GTM solutions based on active...

Navigating consists of coordinating egocentric and allocentric spatial frames of reference. Virtual environments have afforded researchers in the spatial community with tools to investigate the learning of space. The issue of the transfer between virtual and real situations is not trivial. A central question is the role of frames of reference in mediating spatial knowledge transfer to external ...
