This paper demonstrates robust video streaming for IPTV over an IEEE 802.16e (WiMAX). In the proposed method, an H.264/AVC video bit-stream is data partitioned according to source coding priority. Raptor channel coding is adaptively applied to the partitioned data. In the event of outright packet drops, redundant partition bearing packets serve to protect priority data. Further, to guarantee a ...

In this paper, we apply a Raptor code-based forward error correcting scheme right above the medium access control (MAC) layer in order to ensure the reliability of the video multicast over IEEE 802.11 wireless LANs (WLANs). Both Raptor code rate and physical layer (PHY) transmission rate are dynamically adapted according to the channel condition. We consider a number of MAC schemes for data tra...

Persecution has continued to negatively impact the density and range of many Bird Prey (raptor) species, both nationally internationally, despite existing legal protection. Departing from relatively small body statistical analyses indicating elevated raptor mortality in proximity shooting estates, this qualitative study draws on in-depth interviews with retired (hence, free employment pressure)...

OBJECTIVE Normal adipose tissue growth and function is critical to maintaining metabolic homeostasis and its excess (e.g. obesity) or absence (e.g. lipodystrophy) is associated with severe metabolic disease. The goal of this study was to understand the mechanisms maintaining healthy adipose tissue growth and function. METHODS Adipose tissue senses and responds to systemic changes in growth fa...

Minnesota contains many areas of good raptor breeding habitat. The open agricultural lands, hardwood forests, coniferous forests, wetlands and combinations of these habitats provide the diversity and productivity necessary to support many species of hawks, owls, and falcons as well as the Bald Eagle and the Osprey. Additionally, the fall and spring migrations funnel thousands of birds through t...

The impact of commercially reared house fly parasitoids released into nine dairy calf coverall facilities were evaluated over 3 yr. Individual and equally mixed ratios of the pteromalid parasitoids Muscidifurax raptor Girault and Saunders and M. raptorellus Kogan and Legner were released at a rate of 500 parasitoids per calf per week for 8 wk. Prerelease, release, and postrelease parasitism was...
