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...

Systematic excavations at the site of the Sima de los Huesos (SH) in the Sierra de Atapuerca (Burgos, Spain) have allowed us to reconstruct 27 complete long bones of the human species Homo heidelbergensis. The SH sample is used here, together with a sample of 39 complete Homo neanderthalensis long bones and 17 complete early Homo sapiens (Skhul/Qafzeh) long bones, to compare the stature of thes...

The genus Kogia, which comprises only two extant species, Kogia sima and Kogia breviceps, represents one of the least known groups of cetaceans in the global ocean. In some coastal regions, however, stranding events of these species have been relatively common over the last decades. Stranding provides the opportunity to investigate the biology of these cetaceans and to explore the epidemiologic...

فرایند sima یکی از فرایندهای تولید مواد اولیه مورد استفاده در فرایند تیکزوفرمینگ است. در این پژوهش اثر فرایند تیکزوفرینگ بر ساختار میکروسکوپی، خواص مکانیکی، نوع شکست و خواص خوردگی آلیاژ a356 تولید شده توسط فرایند sima بررسی شد. با استفاده از نتایج بدست آمده یک پارامتر ترکیبی به نام شاخص spa معرفی شد. این پارامتر خواص مکانیکی و مکانیزم شکست نمونه های تیکزوفرم شده آلیاژ a356 را به اندازه کشیدگی و...
