particular location for nesting from all possible sites (Burger 1985). The exact location of a nest may have important consequences for breeding success, for example influencing predation risk (Regehr et al. 1998) or probability of flooding (Lauro & Burger 1989). Consequently, birds carefully choose nest-sites in order to maximize their possibilities of a successfully breeding outcome. Nest-sit...

in this study, in addition to estimating meat demand, live animal supply and marketing services supply for beef and lamb, economic behavior of marketing margin with respect to determinants of meat demand, live animal supply and marketing services supply have been evaluated for years 1998-2004. results indicate that, as examples, beef and lamb marketing margin elasticity with respect to feed pri...

Exact solutions of nonlinear partial differential equations (NPDEs) are obtained via the enhanced (G'/G)-expansion method. The method is subsequently applied to find exact solutions of the Drinfel'd-Sokolov-Wilson (DSW) equation and the (2+1)-dimensional Painlevé integrable Burgers (PIB) equation. The efficiency of this method for finding these exact solutions is demonstrated. The method is eff...

In this paper, a sensor fusion technique is proposed for Autonomous Underwater Vehicles (AUVs) to track underwater cables. The work presented here is an extension of the vision based cable tracking system proposed in [1,2,3,4]. The focus of this paper is to solve the two practical problems encountered in vision based systems; namely 1) navigation of AUV when cable is invisible in the image, and...

Although beef demand improved modestly in 1999, 20 years of declining demand has plagued the beef industry. Inflation-adjusted retail beef prices were collapsing at the same time per capita consumption was declining. The result, beef demand declined precipitously from 1980 through the late 1990s. For example, Purcell’s beef demand index indicates 1998 Choice retail beef prices were 50 percent l...
