Mountain beech (Nothofagus solandri var. solandri) trunk diameters were measured in each of two catchments, a control, and a stream catchment (a putative lahar path), to assess the vulnerability of a hut sited on the Wakapapaiti Stream, Tongariro National Park, to disturbance events. Beech forest margins were more abrupt, terraced, and were adjacent to rocky areas in the stream catchment, while...

1. Anthropogenic activities in prairie streams are increasing nutrient inputs and altering stream communities. Understanding the role of large consumers such as fish in regulating periphyton structure and nutritional content is necessary to predict how changing diversity will interact with nutrient enrichment to regulate stream nutrient processing and retention. 2. We characterised the importan...

Data stream mining has become a research area of some interest in recent years. The key challenge in data stream mining is extracting valuable knowledge in real time from a massive, continuous, dynamic data stream in only a single scan. Clustering is an efficient tool to overcome this problem. Data stream clustering can be applied in various fields such as financial transactions, telephone reco...

The discharge of grains from a hopper or silo has received considerable attention, both because it is relevant to numerous industries, and a model system for examining general features of granular flow [1, 2]. These studies have generally focused on the motion of grains inside the hopper and the flow rate of material out of the nozzle. It is known that these systems can exhibit intermittent jam...

Fluvial processes and channel development on landscapes have recently received more attention as designers attempt to establish or replace natural streams on disturbed or degraded sites. Several approaches using similar parameters have been developed to evaluate stream development and erosion processes on natural soils and landscapes. Such approaches include the Manning’s and stream power equat...

At 1 AU there is a distinct boundary (the stream interface) at the leading edge of a stream in the solar wind, characterized by an abrupt drop in density, a similar increase in temperature and a small increase in speed. In some cases this is a tangential discontinuity; in others it is probably evolving into a tangential discontinuity. It is suggested that stream interfaces form in the interplan...
