Abstract English for Specific Purposes (ESP) and Needs Analysis (NA) have been studied to a great extent, since couple of decades ago. The review the related studies also shows that needs analysis has much concern researchers interested in ESP field. However, students marine engineering not investigated terms task-based language needs. used quantitative survey. To collect data, researc...

information on animal daily forage needs is essential for an estimation of rangeland grazing capacity. accordingly, weight and animal unit equivalent (aue) for each individual class of animal should be determined. live weights of baloochi sheep as based on average live weights of 3 and 4 year old ewes were determined. five herds of baloochi breed sheep were selected for the task. in each herd, ...

In knowledge-based organizations, workers need task-relevant knowledge and documents to support their task performance. A knowledge flow (KF) represents the flow of an individual’s or group members’ knowledge-needs and the referencing sequence of documents in the performance of tasks. Through knowledge flows, organizations can provide task-relevant knowledge to workers to fulfill their knowledg...

Quantizers play a critical role in digital signal processing systems. Recent works have shown that the performance of acquiring multiple analog signals using scalar analog-to-digital converters (ADCs) can be significantly improved by prior to quantization. However, design such hybrid quantizers is quite complex, and their implementation requires complete knowledge statistical model signal. In t...

Different methods of language teaching have tried to help EFL learners to develop good language skills based on their various perspectives. Research findings have underscored the effect of using task types in promoting language skills in terms of accuracy in written discourse. Therefore, this study set out to investigate whether there is an evidence of correct use of simple past tense (Accuracy...

This paper investigates an ensemble feature selection algorithm that is based on genetic algorithms. The task of ensemble feature selection is harder than traditional feature selection in that one not only needs to find features germane to the learning task and learning algorithm, but one also needs to find a set of feature subsets that will promote disagreement among the ensemble’s classifiers...
