Invasive Weed Optimization for Combined Economic and Emission Dispatch Problems

In this paper, Invasive Weed Optimization (IWO) algorithm is used to find the optimum solution of Combined Economic Emission Dispatch (CEED) problem. The main objective is to minimize the fuel cost as well as emission level, while satisfying the power demand and associative operational constraints. The bi-objective problem is made to a single objective function using the price penalty factor. S...

Duckling Survival of Mallards in Southland, New Zealand

The southern portion of New Zealand’s South Island is a productive area for mallards (Anas platyrhynchos) despite a notable lack of permanent or semi-permanent wetlands. Most broods are reared in pastures that may or may not be flooded with ephemeral water. In recent years, there has been an increased conversion from continuous to sporadic grazing that has resulted in a functional change in the...

The sand dunes of Kawakaputa Bay and Haldane Bay, Southland

The Conservation Estate, administered by the Department of Conservation (DOC), contains areas of land of undetermined conservation value. These include coastal lands, obtained and managed by the Government of the day for other than conservation purposes. One such purpose was to stabilise coastal sand dunes where drifting sands presented a hazard to adjacent railway lines or roads. The Sand Drif...
