In recent years, Android has gained a lot of popularity with smartphone users, making it a target platform for malware. To protect the user, Android uses a permission system which limits an application’s access to private data. However, the users have no fine-grained control over which permissions are granted to the application. In order to mitigate this problem, this project introduces a novel...

First published September 16, 2015; doi:10.1152/ajpregu.00164.2015.—An adequate supply of oxygen is important for the survival of all tissues, but it is especially critical for tissues with high-energy demands, ...

IEEE 802.11 called service integration multiple access (SIMA) is proposed in this paper. SIMA is designed to support voice and data transmissions over wireless local area networks (WLANs). Since both voice and data traffics have different characteristics and service requirements, we use a hybrid scheme between time division multiple access (TDMA) which is suitable for constant-bit-rate (CBR) vo...

An adequate supply of oxygen is important for the survival of all tissues, but it is especially critical for tissues with high-energy demands, such as the heart. Insufficient tissue oxygenation occurs under a variety of conditions, including high altitude, embryonic and fetal development, inflammation, and thrombotic diseases, often affecting multiple organ systems. Responses and adaptations of...

Photorealistic 3D models, representing an object’s surface geometry textured with conventional photography, are used for visualization, interpretation and spatial measurement in many disparate fields, such as cultural heritage, archaeology and throughout the earth sciences, including geology. Virtual models of geological outcrops allow for large quantities of geometric data, such as sizes of fe...

ABSTRACT Dwarf sperm whales (Kogia sima) are small toothed that produce narrow-band high-frequency (NBHF) echolocation clicks. Such NBHF clicks, subject to high levels of acoustic absorption, usually produced by small, shallow-diving odontocetes, such as porpoises, in keeping with their short-range and fast click rates. Here, we sought address the problem how little-studied deep-diving Kogia ca...

The evolution of IP and ATM share some common drivers. Both of them are addressing efficient network resource utilisation. In order to evaluate the options and combinations offered by these technologies the DIANA project is looking into the areas where ATM and IP both overlap and complete each other, that is QoS interworking between ATM and IP. This is achieved by investigating RSVP-over-ATM ap...
