Both Royal Australian Air Force (RAAF) and Border Protection Command (BPC) aircraft fly maritime surveillance missions for the Australian Government on a regular basis. These missions involve searching particular areas of interest (AIs) for illegal fishing or people smuggling activities. In this work a square AI is considered, with an aircraft tasked to search for ships using its sensors (e.g.,...

The ability to detect conception and/or conception failure in cattle would be beneficial to producers in formulating reproductive management plans. A new diagnostic test, the early conception factor (ECF) test, has been developed forthis application yetthe accuracy of this test has not been adequately determined. The objectives of this study were to evaluate the effectiveness of the ECF test fo...

STUDY OBJECTIVE To study the effect of the antioxidant N-acetylcysteine (NAC) in the development of elastase-induced emphysema in rats. MATERIALS AND METHODS Wistar rats (n = 72) were orotracheally instilled with 75 IU elastase or saline solution. Eighteen rats from each group received the antioxidant NAC from 2 days before induction of the lesion until they were killed 2, 8, and 28 days afte...

Algebraic attacks have received a lot of attention in studying security of symmetric ciphers. The function used in a symmetric cipher should have high algebraic immunity (AI) to resist algebraic attacks. In this paper we are interested in finding AI of Boolean power functions. We give an upper bound on the AI of any Boolean power function and a formula to find its corresponding low degree multi...

In the discussions on the limitation of Artificial Intelligence (AI), there are three major misconceptions, which identify an AI system with an axiomatic system, a Turing machine, and a system with a model-theoretic semantics, respectively. Though these three notions can be used to describe a computer system for certain purposes, they are not always the proper theoretical notions when an AI sys...

BACKGROUND Flock surveillance systems for avian influenza (AI) virus play a critical role in countries where vaccination is not practiced so as to establish the epidemiological characteristics of AI needed for the development of prevention and control strategies in such countries. MATERIALS AND METHODS As part of routine AI monitoring in southwest Nigeria, a competitive ELISA was used for det...

The food habits and niche overlap based on diet composition and prey size of two species of understorey insectivorous birds were investigated in an area of montane rain forest in the state of Minas Gerais, southeastern Brazil. A total of 43 birds were captured: 33 individuals of Conopophaga lineata (Conopophagidae) with 13 recaptures, and 10 individuals of Myiothlypis leucoblephara (Parulidae) ...
