Pigeons (Columba livia) searched for food hidden in the center of a square enclosure. On occasional tests without food, the enclosure was (a) unchanged from training (control tests), (b) moved to different corners of the testing room (corner tests), or (c) doubled in size (expansion tests). The birds showed localized search in the center of the enclosure on control and corner tests. On expansio...

The National Zoological Gardens of South Africa (NZG) is involved in the ex situ conservation of Gyps coprotheres, the Cape Griffon vulture (CGV) and houses 24 birds in a 100-yr-old aviary. Following the death of one vulture with high liver lead concentrations, an investigation was launched to ascertain the source(s) and consequences of lead toxicity in this breeding colony. Whole blood from 24...

Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and...

We introduce a new type of probabilistic boundary coverage problem where a robot has to enclose unknown target fields (UTFs) with large perception uncertainty and limited sensing range. When the robot gets closer to UTF and accumulates sufficient sensory readings, it employs Gaussian processes (GPs) as a local belief function to approximate field boundary distribution in an ellipse-shaped local...

This report describes a low cost, shielded enclosure that was developed to contain the electromagnetic radiation generated by electronic equipment in order to reduce the potential for radio frequency interference (RFI). The enclosure is made from thin wire mesh screening that is attached to a wooden framework for support. Allowances are made at both ends of the enclosure for large cable bulkhea...

We give a short survey on methods for the enclosure of the solution set of a system of linear equations where the coefficients of the matrix and the right hand side depend on parameters varying within given intervals. Then we present a hybrid method for finding such an enclosure in the case that the dependency is polynomial or rational. A general-purpose parametric fixed-point iteration is comb...

Several recent studies have shown that chickens, fish, and humans trained to find a reward in a corner of a rectangular enclosure with distinctive features rely more on the geometry of the enclosure in small enclosures and rely more on the features in large enclosures. Here, these results are modeled using a recent associative model of geometry learning [Miller, N.Y., Shettleworth, S.J., 2007. ...

Fluids have played and still play a vital role in attaining an optimized output from industrial processes. However, due to technological advancement, fluids with high hydrothermal characteristics are required. In order overcome these challenges, researchers developed dispersed nanoparticles, which recognized as nanofluids. Various types of nanoparticles can be added base produce thermally enhan...
