Soil Compaction and Soil Tillage – Studies in Agricultural Soil Mechanics

Keller, T. 2004. Soil Compaction and Soil Tillage Studies in Agricultural Soil Mechanics Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6769-1 This thesis deals with various aspects of soil compaction due to agricultural field traffic, the draught force requirement of tillage implements and soil structures produced by tillage. Several field experiments were carried out to study the mechanic...

Soil mechanics: breaking ground.

In soil mechanics, student's models are classified as simple models that teach us unexplained elements of behaviour; an example is the Cam clay constitutive models of critical state soil mechanics (CSSM). 'Engineer's models' are models that elaborate the theory to fit more behavioural trends; this is usually done by adding fitting parameters to the student's models. Can currently unexplained be...

The Role of Micro-Mechanics in Soil Mechanics

COMPONENTS FOR IMMERSION Alexandre

A person is immersed when they feel part of an environment they experience and influence. While virtual immersion systems are usually designed on a case by case basis, and are not easily reusable or scalable, our goal is to specify and develop a framework for the design and integration of immersive systems. We address the issues raised in the design and implementation of the middleware componen...

This paper presents the Clustering Search (CS) as a new hybrid metaheuristic, which works in conjunction with other metaheuristics, managing the implementation of local search algorithms for optimization problems. Usually the local search is costly and should be used only in promising regions of the search space. The CS assists in the discovery of these regions by dividing the search space into...
