Assessment of the suitability for agriculture of the north-west Packsaddle area Kununurra

A brief assessment of the suitablility for agriculture of about 260 ha in the North-west Packsaddle area was conducted in early September 1993. Nine map units based on soil and landform were identified, and their suitability for broadscale flood irrigated agriculture and spray or trickle irrigated horticulture assessed. The map units are based on field observations and extrapolation from existing surveys. The map was prepared at a scale of 1:20,000 and is only accurate at that scale

Assessment of the suitability for horticulture of the Packsaddle infill area, Kununurra

A brief assessment of the suitability of 142 ha in the Packsaddle infill area for horticulture was conducted in late August 1993. Of this area 100 ha is Crown Land, and 42 ha was recently sold as freehold. Eleven map units based on soil and landform were identified, and their suitability for horticulture assessed. The map units were based on field observations and extrapolation from existing surveys

Hierarchical reinforcement learning with multi-step actions

In recent years hierarchical concepts of temporal abstraction have been integrated in the reinforcement learning framework to improve scalability. However, existing approaches are limited to domains for which a decomposition in subtasks is known a priori. In this paper we propose the concept of multi-step actions on different time scales in one single action set. It is suited for learning optimal policies in unstructured domains where a decomposition is not known in advance or does not exist at all. At the same time this approach enables learning at multiple levels of temporal abstraction. Thus, multi-step actions offer the possibility to obtain faster learning algorithms for unstructured domains

LS3: Latent Semantic Analysis-based Similarity Search for Process Models

Large process model collections in use today contain hundreds or even thousands of conceptual process models. Search functionalities can help in handling such large collections for purposes such as duplicate detection or reuse of models. One popular stream of search functionalities is similarity-based search which utilizes similarity measures for finding similar models in a large collection. Most of these approaches base on an underlying alignment between the activities of the compared process models. Yet, such an alignment seems to be quite difficult to achieve according to the results of the Process Model Matching contests conducted in recent years. Therefore, the Latent Semantic Analysis-based Similarity Search (LS3) technique presented in this article does not rely on such an alignment, but uses a Latent Semantic Analysis-based similarity measure for retrieving similar models. An evaluation with 138 real-life process models shows a strong performance in terms of Precision, Recall, F-Measure, R-Precision and Precision-at-k, thereby outperforming five other techniques for similarity-based search. Additionally, the run time of the LS3 query calculation is significantly faster than any of the other approaches

Soils of the Knox Creek Plain East Kimberley Western Australia and Northern Territory

An assessment of the soils and landforms of approximately 12,000 ha in the Knox Creek Plain in Western Australia and the Northern Territory was conducted in May and June 1994. Seventeen map units were identified and their soils, landform and vegetation characteristics were described. Grey or brown cracking clays predominate on the plain, however variable red or brown soils on the coarser alluvium of remnant levees are common in the south and south-east

Soils of the Mantinea Loop Ord River Valley East Kimberley Western Australia

A brief assessment of the soils of 1,186 hectares in the Mantinea Loop, and their suitability for irrigated agriculture, was conducted in June 1994. Four map units based on soil, landform and vegetation were identified. The soils are mainly calcareous brown fine sandy loams. The landform is an alluvial plain, with numerous small depressions and channels caused by the meandering and flooding of the Ord River

Soil groups of Western Australia: a simple guide to the main soils of Western Australia (4th edn)

This publication provides a simple, standardised and easy-to-understand way to recognise the most common soils in Western Australia. It is designed to: 1) Provide a standard way of giving common names to the main soils of the State; 2) Provide a simple method to identify them; 3) Assist with the communication of soils information at a general level

Land systems of the Kimberley region, Western Australia

The Land Systems of the Kimberley Region Report describes and maps the landscapes, soils and vegetation of the Kimberley region. This report is a consolidation of surveys carried out by different organisations, across different areas of the Kimberley, since the 1940s. The Kimberley region, as defined in this bulletin, covers 330 070km². The report categorises the Kimberley region into 111 land systems. Under each land system, the report identifies the vulnerabilities of those areas, and provides recommendations on how to achieve sustainable use. The report also publishes pasture types for the entire region and the grazing potential for each pasture, ranging from high to very low

Approach range and velocity determination using laser sensors and retroreflector targets

Rockwell International is conducting an ongoing program to develop Laser Docking Sensors (LDS) that provide high performance and high intrinsic value while meeting all mission objectives. These LDS systems are now being required to aid future spacecraft docking, station keeping, and berthing/capture systems. Improved automated tracking, rendezvous, soft docking, and capture will be required in the construction and support of SSF and future orbiting platforms. The development of a practical LDS requires an easy-to-operate, low-cost, compact system. A wide range of options for laser range detection equipment, ranging from commercial technology to specialized military systems, was evaluated. This evaluation focused on both direct applicability of existing systems and usability of specific technologies contained in these systems. From these efforts it was determined that a new approach provided the greatest promise of fulfilling all mission requirements at the lowest life-cycle cost
