BACKGROUND The role of nurses in providing high quality healthcare to patients is so important that creating a desirable working environment to enhance their overall performance is unavoidable. This paper aimed to explore the impact of psychological capital on mental health by investigating the mediating effects of job burnout on this relationship. METHODS AND MATERIAL The data used in this r...

We study a variety of image deblocking algorithms for improving quality of visual signals degraded by blocking artifacts from compression. The image improvements afforded by these algorithms is measured using the PSNR, PSNR-B, and SSIM. Rather than relying on PSNR, which correlates poorly with subjective judgment, we propose a new Deblocking quality index that is sensitive to blocking artifacts...

We develop Markov models for various schedulers in order to evaluate their performance tradeoffs at wireless links. While FIFO scheduling aggregates flows into a single flow just prior to the wireless link, Channel-State Dependent (or CSD) schedulers maintain a queue for each flow, and use predicted channel information to make scheduling decisions. We present results of tradeoffs in terms of ov...

In mobile applications, the energy consumed by OS and application tasks primarily comes from limited DC battery source, which imposes an upper bound to the amount of time available for execution of tasks. To achieve the best Energy-aware Quality-of-Service (EQoS), it is important to prioritize the scheduling of critical tasks over non-critical tasks to improve overall performance while extendin...

The assessment of image quality is very important for numerous image processing applications, where the goal of image quality assessment (IQA) algorithms is to automatically assess the quality of images in a manner that is consistent with human visual judgment. Two prominent examples, the Structural Similarity Image Metric (SSIM) and Multi-scale Structural Similarity (MS-SSIM) operate under the...

Structural change plays an important role in developing any economy, so understanding it is critical to make policies that increase total factor productivity. The structural change that leads to an efficient resource allocation after trade reforms is desirable; the key factor that can affect the relation of "structural change and trade liberalization" with productivity is the quality of institu...
