Comparative Study of Scheduling Algorithms in LTE HetNets with Almost Blank Subframe

The trend and human lifestyle have been changing, which lead to the tremendously increasing demand for data usage over wireless communication systems even on the go. Traffic offload has been used for LTE Heterogeneous Networks (HetNets) to optimize overall system capacity via load balancing mechanisms among network tiers. In this work, the two main techniques used for interference coordination in the multi-tier systems i.e. Almost Blank Subframe (ABS) and Cell Range Expansion (CRE) have been focused on. Resource scheduling is one of the major issues in LTE HetNets aimed at efficient radio resource allocation. Based on the implementation of ABS and CRE mechanisms, this work investigates the system performance while different scheduling schemes are implemented. Five scheduling schemes including Round Robin (RR), Best-Channel Quality Identification (Best-CQI), Maximum Throughput (Max-TP), Proportional Fairness (PF), and Resource Fairness (RF) are considered here. The simulation studies include a comparison of the LTE HetNet system performance under different ABS and CRE configured parameters as well as employing different scheduling mechanisms. System performance is observed in terms of the average throughput, the peak throughput, the edge throughput, and the fairness index. The results provide recommendations on the system configurations as well as the choice of a scheduler that can be considered or suitable for different scenarios and network planning objectives. Coined from these results, the Best-CQI and the Max-TP mechanism offer the highest peak throughput and the high average throughput. The RR, PF, and RF provide the high cell edge throughput and fairness index, however, the peak throughput has been compromised

Mixing-Performance Evaluation of a Multiple Dilution Microfluidic Chip for a Human Serum Dilution Process

This paper is aimed to propose a numerically designed multiple dilution microfluidic chip that can simultaneously deliver several serum dilutions in parallel. The passive mixing scheme is selected for dilution and achieved by the serpentine mixing channel in which Dean vortices are induced to increase the contact area and time for better diffusion. The mixing performance at the exit of this dilution chip is numerically evaluated using five commonly-used mixing indices with the goal that the homogeneity of the mixture over the exit cross-sectional area of the mixing channel must be greater than 93.319% to fulfill the six-sigma quality control

Knowledge sharing for pediatric pain management via a web 2.0 framework

The experiential knowledge of pediatric health practitioners encompasses vital insights into the clinical efficacy of diagnostic and therapeutic methods for pediatric pain management. Yet, this knowledge is not readily disseminated to other practitioners and translated into practice guidelines. We argue that a peer-to-peer knowledge sharing mechanism can serve as a key change agent to improve the attitudes, beliefs and methods for pediatric pain management. We are using collaborative technologies, in the realm of Web 2.0, to develop a web-based knowledge sharing medium for fostering a community of pediatric pain practitioners that engages in collaborative learning and problem solving. We present the design and use of a web portal featuring a discussion forum to facilitate experiential knowledge sharing based on our LINKS knowledge sharing model

Children's pain assessment in Northeastern Thailand : perspectives of health professionals

Deficiencies in pain care within the developing world are starting to be realized. Children, in particular, are vulnerable, as preliminary studies suggest that these children receive less pain treatment because of health professionals’ attitudes and beliefs. This article reports on some of the findings of the first study in a larger program of research aimed at improving pediatric pain care in Thailand. Improvements in practice are not simply the result of providing evidenced-based knowledge, but a complex process that includes the context of care. Given that little is known about the pain management experiences of Thai health professionals, including the challenges they face, we used focus groups to capture their stories. Data revealed a need for both updating pain knowledge and for supporting an increased use of appropriate practices. In this article, we focus on the issues concerning the assessment of pain resulting from underrecognizing children’s pain and complex issues in communicating findings of children’s pain
