Borehole heat exchangers, especially deep ones, are usually drilled through different geological layers having varying properties. Homogeneous and layered models can be used for borehole performance predictions. The homogeneous model considers all as a single layer effective properties while the separately gives better accuracy, although it is more complicated time consuming to calculate. In th...

This paper proposes an algorithm that can reduce the estimation error of surface spectral-reflectance(SR) when using a conventional 3-band RGB camera. In the proposed method, the estimation error is reduced by using adaptive principle components(PCs) for each color region. To build an adaptive set of PCs, n SR populations are organized for n PC sets using the Lloyd quantizer design algorithm. T...
This paper describes the contributions of rapid ethnography to the design of a web-enabled educational toy, specifically installation and registration. While HCI practitioners increasingly advocate rapid ethnography for early discovery and requirements phases, we discuss the role played by ethnography that spans open ended observation, story telling, conceptual design and iterative prototype ev...
the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...

Traumatic brain injury (TBI) is described as a situation in which the brain is damaged by an external force. It is considered to be a chief problem in health care. Pharmacotherapy and stem cell therapy are the main treatments used in TBI. The purpose of these procedures is to control the inflammation in injured regions of brain.

the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
