Nowadays there is a plethora of independent radio access technologies (RATs), each supporting distinct coverage, mobility, data rates, and quality of service (QoS). The cornerstone of all visions on future wireless networks is that there will be a multiaccess network environment, where users will be able to select from various available multiple heterogeneous access networks the most appropriate one to satisfy specific application requirements. On the other hand, emerging applications call for the vehicular networks to support multimedia and real-time services. © 2010 IEEE. Source

Richard Shim discusses how tablets impact the notebook market. The tablet PC, in its short lifetime, has already influenced the mobile PC market in numerous ways, but none more concretely than in inspiring the emergence of the Ultrabook. The notebook market is not in decline, but the shipment forecast is not anywhere near as promising as that of the tablet market. In 2011, DisplaySearch estimates over 72.8 million tablets will ship, as compared to 187.5 million notebooks. By 2015, tablet shipments will reach 271.1 million units, as compared to 332.5 million notebooks. For 2011, DisplaySearch estimates over 71 million tablets using ARM processors will ship, and by 2015 that number is expected to increase to nearly 258.3 million units. The role of ringleader among Ultrabook backers in large part belongs to Intel. Though Apple's MacBook Air can arguably be pointed out as the first notebook to fit the Ultrabook description, Intel has been working to define the category and to lower it from premium status to make it available to the mainstream market.

The challenge of estimating video quality in video communication applications is discussed. Video delivery over modern communication networks is becoming ubiquitous through its use with an ever larger range of different applications. For the viewer to experience high-quality video, the captured video should have minimal undesired attribute. The compressed video may be afflicted by compression artifacts, such as blocking, ringing, or blurring. The display device, environmental viewing conditions, and viewer have a significant effect on the perceived quality. A video quality estimator (VQE) need only be effective for its intended usage. Full-reference VQEs require access to both the decoded video and the original video in the same physical location to estimate the quality. No-reference pixel-based VQEs attempt to estimate quality by decoding the video but without access to the original. No-reference bit stream-only VQEs attempt to estimate quality without completely decoding the video to obtain decoded pixels. Source

Recent advances in plating technology for the pediatric femur fracture have demonstrated early mobilization of the extremity and early weight bearing. Submuscular techniques allow for minimal soft tissue disruption and provide a theoretical healing advantage. This article presents results of the treatment of pediatric femur fractures using a locked submuscular bridge plating technique. The authors reviewed 16 patients between 6 and 12 years of age who sustained a femoral shaft fracture treated with minimally invasive submuscular locked plating. Patients were followed for an average of 25 months and made full weight bearing within 6 weeks of surgery. All patients achieved radiographic and clinical union with an average time of 2.6 months. Range of motion of the knee and hip were equivalent to the contralateral extremity at 2.1 months. Average time of hardware removal was 11 months. Benefits of locked plating of pediatric femur fractures include high union rates, early weight bearing, early recovery of range of motion, and minimal complications. Source

The use of smart antennas in multihop wireless networks has garnered significant attention over the last few years. Given the unique capabilities of smart antennas, and how they can improve performance in a typically constrained multihop wireless network (MWN) environment, the attention is with merit. However, not much light has been shed on MWNs that have nodes with varying antenna capabilities. While homogeneous MWNs with all nodes having the same antenna capabilities will have certain applications, we argue that MWNs with nodes having heterogeneous antenna capabilities are more likely to be the norm due to a variety of motivating factors. In the context of such heterogeneous smart antenna networks (HSANs), we investigate and motivate the need for a simple form of node cooperation called retransmit diversity. We show that while such a simple form of node cooperation cannot bring significant benefits to homogeneous omni-directional antenna networks, they can bring great gains (several folds improvement) to heterogeneous smart antenna networks. We then present several key properties pertaining to node cooperation in HSANs along with analytical reasoning. In the process, we identify a fundamental trade-off between exploiting smart antenna gain and cooperation gain, that undermines the ability of HSANs to leverage node cooperation to their maximum potential. To address this trade-off, we then present an adaptive cooperation mechanism and incorporate this mechanism through the design of a simple but efficient MAC protocol. The performance of the MAC protocol is evaluated through ns2 simulations along with a realistic physical layer channel model for smart antenna environments. © 2006 IEEE. Source
