THE ECONOMICS OF MOBILE INTERNATIONAL ROAMING
International roaming is a hot topic in the telecommunications industry. Many countries have witnessed a downward trend in mobile domestic prices. On the contrary, international roaming prices remained reluctant to follow the domestic trend. In Europe, the service has been regulated with price cap …

Improving rabies control in free-roaming dogs
… in Asia and Africa where domestic dogs are free-roaming. The disease can be effectively controlled through vaccinating at least 45% of the dogs in a population; however the impact of vaccinations on disease incidence may be affected by dynamic demographic and immunological processes. …

A cross-layer mobility management framework for next-generation wireless roaming
… that allows the challenges of next-generation roaming to be met. The framework features tools that gather context and content information, guarantee low-level QoS, provide security, and offer link and handoff management. The framework aims to be scalable and reliable for all-IP heterogeneous …

Evaluation of roaming and download times in universal cellular/wireless LAN systems
… environment as for example in the case of global roaming. There are a great number of international organizations and forums for software defined radios around the world. In this thesis, a generalized state diagram of a SDR reconfigurable, multi-mode mobile station that could roam/handoff between …

Quantifying Ungulate-Rangeland Interactions: From Monitoring Free-Roaming Horse Condition to Vegetation Response Following Herbivore Exclusion
… a quantitative framework for calibrating free-roaming horse body-condition scores from camera-trap imagery, comparing observer and veterinarian assessments to correct qualitative bias. The second analyzes a seventeen-year record of herbivory removal in a winterfat-dominated community in …

The photodissociation of small Aldehydes: a refined understanding of prototypical dynamical systems
… the T1 and So surfaces dominant elsewhere. The roaming channel branching fraction is constant, accounting for -20 % of CO produced. Roaming occurs on a timescale shorter than the vibrational predissociation of HCO. The quantum yield of the triple fragmentation channel grows exponentially above …

`ROAMING IN THE GARDEN OF FREEDOM:' CONSTRUCTIONS OF U.S. IDEOLOGY, IDENTITY, AND THE PAST IN TELEVISION NEWS'S ANNIVERSARY COVERAGE ABOUT THE BERLIN WALL
<p>This study employs a multimodal close reading to examine and compare how NBC's Nightly News and various primetime CNN news shows construct the story of the Berlin Wall's opening from 1990 through 2009. It does so first by examining the networks' 1989 coverage and assessing the themes and …

Soft Mobility Techniques For Ensuring Network Availability
… of Denial-of-Service (DoS) attacks. Adaptive roaming replica scheme is proposed for ensuring the availability of the data and Dynamic Early Filtering of Internet Traffic (DEFT) is proposed for ensuring the availability of network resources.</p> <p>For ensuring data availability, the current …

Sensory and Neuromodulatory Entrainment of Foraging States in C. Elegans
… behavior: previously described high arousal roaming and low arousal dwelling states reflect long-term changes in locomotory patterns, whereas an Autoregressive Hidden Markov model that classifies behavior on shorter time scales effectively segments food leaving behaviors. Adaptive foraging …

Technology in ecology: determining the location, behaviour, and energy expenditure of free-ranging carnivores
… data to improve accuracy when monitoring free-roaming animals. Furthermore, I examine how urban environments and seasons influence the roaming behaviour of domestic cats (Felis catus), and quantify how large wild predators, mountain lions (Puma concolor), minimise energetic costs in …

The Wild Diamond Diaries: Healing Alongside America's Wild Horses
<p>To some, America’s free-roaming Mustangs and burros symbolize liberty and beauty. To others, these equines are feral at best, invasive at worst. They have a reputation for being useless, destructive, and untrainable. Yet my childhood horse—gifted to my family when I was three—was a gentled …

Inactivity and overfeeding related changes in skeletal muscle composition and metabolism in captive felids - are they at risk of developing metabolic syndrome?
… are physically inactive, with a group of free roaming wild lions. Skeletal muscle biopsies were collected from the Triceps brachii and analysed for fibre type composition, fibre size, and maximum oxidative (citrate synthase (CS), 3-hydroxyacyl CoA dehydrogenase (3HAD) and glycolytic …

Genetic Analysis of Bacterial Food Perception and its Influence on Foraging Behavior in C. elegans
… and foraging behaviors known as dwelling and roaming; scd-2(syb2455) animals roam more and scd-2 loss-of-function animals roam less than wild type. Additionally, in contrast to wild-type animals, which express the gene encoding the TGF- signaling ligand DAF-7 exclusively in the ASI …

Quality of food and voluntary intake of male impala (Aepyceros melampus) in the Timbavati area
The study was conducted on free-roaming male impala in the Timbavati Private Nature Reserve. The aim was to obtain information on quality of diet selected during different seasons, to determine intake and to convert this data into estimates of energy requirements which can be used when calculating …

Characterizing the Role of Magnetic Cues Underlying Spatial Behavior
… to collect behavioral and spatial data from free-roaming mammals. Specifically, a previous observational study of free- roaming red foxes found a 4-fold increase in the success of predatory 'mousing' attacks when foxes were facing ~north-northeast, consistent with magnetic alignment responses …

MOVING THE GOALPOSTS: MIGRATORY BIRDS IN A CHANGING WORLD
… and abundant introduced predators such as free-roaming domestic cats (Felis catus), yet their behavioral responses to cats have been little studied during migration. Using an aviary experiment, I exposed wild Gray Catbirds Dumetella carolinensis to either a hawk or a domestic cat and observed …

Habitat use, feeding ecology and the impact of re-introduced elephants (Loxodonta africana) on trees within a restricted conservation area in the semi-arid, Little Karoo, South Africa
The reintroduction of free-roaming elephants on the 540 km2 Sanbona Wildlife Reserve in the Little Karoo, Western Cape, South Africa, raised concerns over the possible negative impacts that these animals may have on the biodiversity of the property, especially the tree component. The main …

Progressively communicating rich telemetry from autonomous underwater vehicles via relays
… – as a result, current telemetry from free-roaming autonomous marine vehicles remains limited to ‘heartbeat’ status messages, with minimal scientific data available until after recovery. Increasing the challenge, longdistance communication may require relaying data across multiple acoustic …
