In a distributed cooperative environment, synchronization is a major issue. Especially when OFDM is employed in the physical layer, frequency offset synchronization is of great significance. In addition, transmitter and receiver IQ imbalances are known to be important implementation issues in OFDM systems. In this paper, the use of a strategy is investigated that enables blind estimation of Car...

Sparse Dictionary Learning has recently become popular for discovering latent components that can be used to reconstruct elements in a dataset. Analysis of sequence data could also bene t from this type of decomposition, but sequence datasets are not natively accepted by the Sparse Dictionary Learning model. A strategy for making sequence data more manageable is to extract all subsequences of a...

After a brief review of the major group cooperative learning strategies, this article presents the format and use of Process-Oriented Guided-Inquiry Learning (POGIL) as a recommended teaching strategy for occupational therapy classes. This recommendation is based upon evidence of effectiveness of this strategy for enhancing critical thinking, content retention, and teamwork. Strategies for lear...

The present study was an attempt to investigate the effectiveness of reading instructional approach called MCSR- Modified Collaborative Strategic Reading on reducing intermediate EFL learner's reading anxiety. Based on a pretest-posttest design, MCSR was implemented with 64 EFL learners at intermediate level. They received EFL reading instruction according to MCSR over two and a half months. A ...

this paper presents a new three-dimensional curvelet transform based dictionary learning for automatic segmentation of intraretinalcysts, most relevant prognostic biomarker in neovascular age-related macular degeneration, from 3d spectral-domain optical coherencetomography (sd-oct) images. in particular, we focus on the spectralis sd-oct (heidelberg engineering, heidelberg, germany) system, and...

This paper considers the advertising, pricing, and service decisions simultaneously to coordinate the supply chain with a manufacturer and a retailer. The amount of market demand is influenced by advertising, pricing and service decisions. In this paper, three well-known approaches to the game theory, including the Nash, the Stackelberg-retailer, and the cooperative game are exploited to study ...

the purpose of this study was twofold. firstly, it attempted to investigate whether language learning strategies (llss) can predict foreign language (fl) proficiency. secondly, it examined what kind of llss iranian learners of english use more frequently in fl institutes. to do so, 112 intermediate iranian efl learners participated in the study. oxford’s strategy inventory for language learning...

Both appt~oaches have their advantages and disadvantages; dictionary lookup fails for unknown words (e.g., proper nouns) and letter to sound rules fail for irregular words, which are all too common in English. Most speech synthesizers adopt a hybrid strategy, using the dictionary when possible and turning to letter to sound rules for the rest. I discussed letter to sound rules at the last meeti...

Cognitive Radio (CR) networks enable dynamic spectrum access and can significantly improve spectral efficiency. Cooperative Spectrum Sensing (CSS) exploits the spatial diversity between CR users to increase sensing accuracy. However, in a realistic scenario, the trustworthy of CSS is vulnerable to Spectrum Sensing Data Falsification (SSDF) attack. In an SSDF attack, some malicious CR users deli...
