Norms have been extensively studied to coordinate multi-agent systems, and the literature has investigated two general approaches to norm synthesis: off-line (synthesising norms at design-time) and on-line (runtime synthesis). On-line synthesis is generally recognised to be appropriate for open systems, where aspects of the system remain unknown at design-time. In this paper we present LION , a...

The paper \Two Practical and Provably Secure Block Ciphers: BEAR and LION" AnBi96] by Ross Anderson and Eli Biham is summarized. The paper presents two new block ciphers (BEAR and LION) which can be built using a hash function and a stream cipher. Both these ciphers are provably secure in that a successful attack on them can be used as an attack on the underlying hash function and stream cipher...

In this paper, we present the development of a reconfigurable hybrid unmanned aerial vehicle (UAV): U-Lion [Ang et al., 11th IEEE Int. Conf. Control Automation (ICCA), pp. 750–755]. U-Lion is a small-scale UAV that is capable of vertical takeoff and landing (VTOL) and fixedwing Cruise modes through its unique mechanical design. Mainly built with carbon fiber and expanded polyolefin (EPO) foam, ...

An 8-yr-old intact female African lion (Panthera leo) presented with a 3-day history of lethargy, anorexia, and vomiting. Hematologic and biochemical abnormalities included a leukocytosis, 41,700/microl (4,700-15,300) with a neutrophilia (37,530/microl; 2,000-9,200) and a left shift (1,250/microl bands; 0-300), and mild hypokalemia of 2.1 mEq/L (2.8-4.8). Abdominal radiographs revealed evidence...

Despite legal protection, deliberate killing by local people is one of the major threats to the conservation of lions and other large carnivores in Africa. Addressing this problem poses particular challenges, mainly because it is difficult to uncover illicit behavior. This article examined two groups of Maasai warriors: individuals who have killed African lions (Panthera leo) and those who have...

Various forms of intensive sport place stress on the musculoskeletal system of the horse, during both racing and training. The musculoskeletal system of the horse has an inherent ability to adapt to the demands of high speed exercise, but exceeding the threshold of adaptive capacity may result in some form of damage. Continuing racing or training may delay the repair process and put the horse a...

In 1972 a conference of biologists from diverse disciplines was held at Washington under the auspices of the Wild Animal Propagation Trust (WAPT), the National Zoological Park, and the New York Zoological Society. Its purpose was to review and summarise information pertinent to marmoset and tamarin biology. It was hoped also that the cross-fertilisation of ideas and knowledge would especially b...

A stranded yearling male California sea lion was admitted to a rehabilitation center June 2003. On presentation, the sea lion was emaciated and had diarrhea and neutrophilia. Two weeks later, the animal became anorexic, blood and mucus were observed around the oral cavity, and corneal opacity was noted in the right eye. Hematology results at that time included leukocytosis consisting of neutrop...
