Abstract:
Stable mine backfill is necessary for safe working conditions, maximum ore recovery and underground and surface stability. Due to the fact that cement costs can be a significant part of the operating costs in large underground mines, the consumption of cement (or binder) should be minimized. Therefore, developing a safe and economical backfilling method for the large underground mining operations is very significant.<br>In this thesis, first laboratory tests and in-situ tests are implemented to determine backfill material properties and backfill stress distribution.

Abstract:
This dissertation is an in depth study of the design and behaviour of tensegrity space structures. It deals with various aspects of these systems including form-finding and analysis. The dynamic relaxation method is employed to develop a software solution for the design and analysis of tensegrity systems with a focus on its application to irregular forms. This method employs an iterative finite difference approach to integrate nodal parameters over time increments.

Landfill covers are designed as impermeable caps on top of waste containment facilities after the completion of landfill operations. Geocomposite drain (GD) materials consist of a geonet or geospacer (as a drainage core) sandwiched between non-woven geotextiles that act as separators and filters. GD provides a drainage function as part of the cover system. The stability performance of landfill cover system is largely controlled by the interface shear strength mobilised between the elements of the cover. If a GD is used, the interface shear strength properties between the upper surface of the G

Abstract:
The motions of a ship in the semi-displacement region are investigated. The focus is on the vertical dynamic forces which should not be neglected at this speed range. Two approaches are used to identify these dynamic forces. The first is an synthetic approach that uses a database of dynamic forces acting on the ship depending on the running attitude and speed of the ship. This database can be obtained from either CFD calculations or experiments.

The objective of this thesis is to investigate the dynamic behaviour of road traffic flow based on theoretical traffic models. Three traffic models are examined: the classical car-following model which describes the variations of speeds of cars and distances between the cars on a road link, the logit-based trip assignment model which describes the variations of traffic flows on road links in a road network, and the dynamic gravity trip distribution model which describes the variations of flows between O-D pairs in an O-D network.

The main limitation of these materials is their reduced macroscopic ductility at room temperature, resulting from an inhomogeneous deformation concentrated in narrows shear bands.

Abstract:
It is well known that boiling water reactors can experience inadvertent power oscillations. When such instability occurs the core can oscillate in two different modes (in phase mode and out of phase mode). In the late 90’s a stability benchmark was created using the stability data obtained from the experiments at the Swedish nuclear power plant of Ringhals-1. Data was collected from the cycles 14, 15 , 16 and 17. Later on, this data was used to validate the various models and codes with the aim of predicting the instability behavior of the core and understand the triggers of such oscillations.

Differences in said behaviour between the different lanthanide metals are attributed to the increasing occupation of the 4f electron shell as Z increases. Upon compression, or as Z decreases, the trivalent lanthanides (La to Lu, excluding Eu and Yb) undergo a common phase transformation sequence through various close packed structures: hcp → Sm-type (the structure adopted by samarium at ambient conditions) → dhcp → fcc → distorted fcc (d-fcc).
